Portable personal weighing scales

Portable personal weighing scales (10) have a platform (12, 14, 28) in the form of a gel-filled cushion made of a foam material. This is rectangular and very low in height (16). Within the gel is a pressure sensor which on one edge of the cushion (22) is attached by a cable to a cylindrical bolster (24) containing the digital weight display (26). The pressure change in the gel when a person stands on the scales is directly related to the weight of the person and is detected by the sensor, converted to a measure of weight and transmitted to the display. For ease of carrying, the scales can be rolled up with the display bolster inside. This helps to protect the sensor and display from damage as well as ensuring that the scales take up little space in luggage. They are also very light in weight.

Apparatus for Continuous Weight Monitoring of Beehives

An apparatus and method for continuously monitoring the weight of an object are disclosed. The apparatus does not obstruct a central portion of the bottom of the object being monitored, and is especially well-suited for monitoring the weight of a beehive. In the illustrative embodiment, a ring-shaped fluid-filled bladder is sandwiched between a ring-shaped top surface and a ring-shaped base, and a pressure hose connects the bladder to a pressure gauge. Beehive weight data can be obtained in a continuous fashion, without requiring any moving of the beehive or of the apparatus, and without any other type of disruption. Moreover, the apparatus provides a stable platform that keeps the beehive immobile during monitoring, which is beneficial for the health of the colony. Advantageously, the apparatus can be constructed from inexpensive, off-the-shelf components and materials, and is capable of obtaining accurate measurements over a wide range of temperatures and environmental conditions.

Method and apparatus for measuring physical properties of matter

A system is described for determining the physical properties of a sample of matter, including the volume, mass and density of the sample. The system uses a single chamber (12), wherein the sample is weighed by a weighing device (14). The chamber is pressurized by a gas of known properties and purity for which the thermodynamic pressure-density-temperature surface is known. As the pressure regulator (40) controls the chamber pressure. As the pressure inside the chamber is changed by regulating the pressure, the apparent weight of the sample, the fluid temperature (36), and the fluid pressure (32) are measured and recorded. A significant feature of the system is the recording of a plurality of weight and fluid density measurements as the pressure in the chamber is changed. The plurality of fluid density measurements results in an improved statistical measure of the sample density. Additionally, the determination of weight at many different densities captures any possible non-linear effects as would be evidenced in compressible media. Thus, the method and apparatus may be used to determine the compressibility or porosity of an object.

Two feeler gauges 10 extend from the beam 1 of a weighing machine each into a slot 11 between nozzles 13 and 14 supplied with air at 30 lbs. / sq. inch through restrictors Rc, RF to provide minimum back pressures of 4 and 4.5 lbs. /sq. inch at chambers 8 and 9 respectively. During the weighing the movement of the feeler gauge in chamber 8 sets up a back pressure which passes to a pneumatic relay C supplied with air at pressure of 25 lbs. / sq. inch and transmits the pressure to relay A which passes the pressure to a valve V1 which deenergizes then to relay B supplied with air at pressure of 80 lbs. /sq. inch which increases the air pressure in the chamber 7 of a section 6 controlling the supply of material from the hopper 5.

Improvements in or relating to fluid pressure transmitting devices

898,381. Dynamometers. HAMILTON, T. W. Jan. 18, 1961 [Jan. 28, 1960], No. 3151/60. Class 106 (2). [Also in Group XVIII] A pneumatic pressure transmissing device comprises a chamber with inlet means for admitting air under a pressure greater than that to be transmitted, an outlet duct in communication with the inlet and downstream thereof and a pneumatic pressure relief opening closed by a loose cover which is acted on by a damper to prevent it from vibrating and which is also acted on by a variable force, e.g. from a weighing machine (see Group XVIII), applied as a thrust along a line of action in alignment with the resultant of the pneumatic pressure in the chamber acting on the cover. When a valve 6 is opened air under pressure, from a source 5, is admitted to the pressure chamber 1 until the downward force is overcome and the cover 11 lifts, allowing air to escape between an annular projection 13, on the cover, and its seating 13a. The movement of the cover is damped by a disc 14 connected by a bolt 15 to the cover and submerged in oil in the bottom of the chamber. When there is equilibrium between the pressure and the downward thrust the valve 6 is closed gradually until the flow through the chamber is very small, under which condition the pressure in the outlet pipe 8 equals that in the chamber 1 and is in linear relation to the variable applied force. The pressure is shown by a gauge 9, calibrated to read directly in force measurement units. Alternatively, the cover 11 may be below the chamber 1, resting on the pivot point 19, its recess 12 forming the main part of the chamber.

Anti-stiction device

The invention relates to a system for determining aircraft weight by detecting the static pressure in the oleo struts of the aircraft, and relates specifically to a system for eliminating errors due to variable stiction (static friction) forces in such systems. In accordance with the invention, the pressure of the gas in the oleo chamber, formed by the walls of the oleo cylinder and the top surface of the oleo piston, is varied from a maximum peak level to a minimum peak level. In order to determine aircraft weight, both above values are detected, and the average of these two values is calculated. Aircraft weight is linearly related to this average value so that the aircraft weight is now determinable. Preferably, the pressure is varied by circulating the gas in the oleo chamber through a heater means to thereby heat the gas, and returning the heated gas to the oleo chamber. The heated gas mixes with the unheated gas in the chamber to raise the temperature of the gas in the chamber and to thereby raise the pressure of the gas in the chamber. After some time, the circulator is stopped, and the gas in the chamber will lose heat to the chamber walls so that the temperature, and correspondingly the pressure, of the gas in the chamber is decreased. Preferably again, the ON-OFF timing of the circulator is automatically controlled.
