Дорожный знак из полимерных материалов

Номер: RU0000209532U1

Автор: Каменчуков Алексей Викторович

Принадлежит: Федеральное государственное бюджетное образовательное учреждение высшего образования "Тихоокеанский государственный университет"

Полезная модель относится к знакам дорожным и может быть использована при строительстве и реконструкции автомобильных дорог, городских улиц и парковых зон для регулирования движения автомобилей и пешеходов, а также их информирования. В процессе эксплуатации корпус и стойка знака приходит в неудовлетворительное состояние под воздействием природных факторов и механического повреждения. Дефектные дорожные знаки подлежат утилизации и замене, что приводит к увеличению расхода невозобновляемых природных ресурсов. Технической задачей, на решение которой направлена заявленная полезная модель, является повышение технологичности изготовления и долговечности деталей знака, а также упрощение крепления знака к стойке. Поставленная задача достигается тем, что дорожный знак из полимерных материалов, включающий основу знака с дополнительными ребрами жесткости, закрепленную к кронштейну на обратной стороне знака, выполненного с возможностью их крепления хомутом к стойке или парной установки основ знака, с креплением их между собой и жесткой фиксации на стойке, причем основу знака и крепления изготавливают с помощью 3D-печати, что обеспечивает высокую точность деталей, причем кронштейны имеют форму прямоугольной пластины с углублением для фиксации стойки и стягиваются между собой элементами соединения (разборного соединения, заклепкой и т.д.), достигается тем, что основа знака выполнена из полимерного материала на основе полиэтилен высокой плотности (HDPE) с каркасом из вертикальных и горизонтальных ребер жесткости с внутренней стороны знака, к которым приваривается кронштейн термопластическим способом.

Foam patterns

Номер: US20120007266A1

Автор: Anil R. Chaudhry, Faurice D. Neece, Nipendra P. Singh, Richard M. Harrington, Robert Dzugan, Travis Westendorf

Принадлежит: FOPAT LLC

A method of creating a foam pattern comprises mixing a polyol component and an isocyanate component to form a liquid mixture. The method further comprises placing a temporary core having a shape corresponding to a desired internal feature in a cavity of a mold and inserting the mixture into the cavity of the mold so that the mixture surrounds a portion of the temporary core. The method optionally further comprises using supporting pins made of foam to support the core in the mold cavity, with such pins becoming integral part of the pattern material simplifying subsequent processing. The method further comprises waiting for a predetermined time sufficient for a reaction from the mixture to form a foam pattern structure corresponding to the cavity of the mold, wherein the foam pattern structure encloses a portion of the temporary core and removing the temporary core from the pattern independent of chemical leaching.

Hybrid method for dental implant treatment planning

Номер: US20120046914A1

Автор: Fei Gao

Принадлежит: Individual

A hybrid method for dental implant treatment planning and a corresponding approach to make a surgical guide. After digital treatment planning is performed with CT scan data, a master model is created, which embodies the patient anatomy and entire treatment plan. Jaw bone, tooth surfaces, soft tissues and nerves are all contained by the master model. The plan details including implant sizes and positions, surgical guide drill options, as well as the choice of a surgical kit, are all conveyed by the master model. Meanwhile, models of specially designed “implant inserts (or replicas)” are also generated, which have one end that fits into the implant holes on the master model and another end to make the surgical guide. The master model and inserts are manufactured with rapid prototyping technology. A surgical guide is later on made from them with conventional lab processes. A main characteristic of this approach is that the master model and the inserts are the physical embodiment of a virtual treatment plan. With them, the surgeons can continue the treatment planning for operations like tooth extractions and bone modifications before making the surgical guides. Therefore the treatment planning workflow is a combination of digital treatment planning and a physical model based planning, in other words, a hybrid approach. A differentiator in this invention is the generation of a closed solid model of the soft tissue, as part of the master model, from the scan data. This approach can be applied to create both bone-borne and tissue-borne surgical guides with low cost process, which is a big advantage over other approaches.

A method of indirect bonding and a physical model that allows for optimal positional alignment of orthodontic appliances on a patient's teeth is disclosed. The physical model of the patient's teeth has pods and ridges on the facial surface of the teeth. Adhesive is applied to an orthodontic appliance and the appliance is placed on a tooth of the physical model against the ridge and on top of the pods. The adhesive fills the space in between the appliance and the facial surface of the tooth and adheres to the model, resulting in a dimensionally correct custom base that is properly aligned with the tooth to account for all five positional elements of a tooth. Once all the orthodontic appliances are applied to the model, the appliances can then be removed from the model and bonded to the patient's teeth in the optimal position using a transfer template.

An inserter can be used to implant a distractible intervertebral body fusion device into a disc space and expand the device. The inserter includes a shaft frame and a drive shaft assembly for expanding the device and a support shaft assembly for stabilizing the device extending distally from the shaft frame. A drive housing can be operably connected to the shaft frame and extend outwardly from shaft frame distal of a proximal end of the shaft frame. Drive housing can have an internal passage that provides access into the shaft frame to a proximal end of the drive shaft assembly. An actuation tool can be disposed with the drive housing with a distal end extending through the access into the shaft frame to interface with the proximal end of the drive shaft assembly such that activation of the actuation tool rotates the drive shaft assembly to expand the device.

Tunable Valve Assembly

Номер: US20140021398A1

Автор: Barbara C. Gilstad, Dennis W. Gilstad

Принадлежит: Individual

A tunable valve assembly reduces valve-generated vibration. One embodiment comprises a valve body and valve seat having substantially collinear longitudinal axes. A rebound characteristic frequency is associated with rebound of the elastic valve body base plate from forceful contact with the valve seat. A central cavity in the valve body encloses a spring-mass damper optionally immersed in a dilatant liquid and having a damper resonant frequency approximating a pump housing resonance. A lateral support assembly adjustably secured to the valve seat has a support resonant frequency designed in conjunction with the rebound characteristic frequency and the damper resonant frequency. Combined hysteresis heat loss associated with the above three vibration frequencies is reflected in lower closing energy impulse amplitude and damping of associated vibrations. Compliance of the elastic valve body base plate mating with the valve seat increases closing energy impulse duration and narrows the corresponding induced vibration spectrum.
