System for introducing additive into a container

ABSTRACT A system for introducing a flowable additive from a capsule to paint, varnish, woodstain or the like in a closed, preferably lidded, container, for example a paint container, modified by the provision of a relatively easily openable inlet into the container. Preferably, the inlet is located in a lid. The capsule comprises a chamber which defines a volume which contains the additive. The system is provided with means for creating an opening in the chamber which can communicate with the inlet and means, preferably a compressible chamber, for positively expelling additive through the opening by contracting the volume which contains the additive. The capsule and container are also provided with co-operable locating means which can co-operate to assist in locating the opening created in the chamber in communication with the inlet. Also, a capsule and a closed container for use in the system and a method of introducing additive using the system. Use of the system reduces the risk of spillage and splashing and permits more controlled tinting of paint and, therefore, is more suitable for use by inexperienced people.

Altitude loss after take-off warning system utilizing time and altitude

ALTITUDE LOSS AFTER TAKE-OFF WARNING SYSTEM UTILIZING TIME AND ALTITUDE Abstract of the Disclosure Warning systems for aircraft that provide a warning to the pilot of an excessive altitude loss or an excessive descent rate after take-off as long as he is flying below a predetermined altitude save the problem that they require a valid radio altitude signal for proper operation, and tend to generate nuisance warnings when used in low flying aircraft. This problem is solved by comparing the accumulated altitude loss after take-off (12, 14, 62, 34) with the product of a barometrically derived altitude and the length of time the aircraft has been flying (12, 14, 30, 32, 34). A warning is generated if the altitude loss is excessive for the accumulated time-altitude product after take-off (38, 40). Thus, the system is more sen-sitive immediately after take-off and becomes less sensitive as flight time is accumulated to permit low level maneuvering without generating false or nuisance warnings, and does not require a valid radio altitude signal to generate a warning.

Limb encircling exercise weight with mounting structures

A bearable exercise weight is disclosed. Several versions of the invention are disclosed, each providing a limb encircling weight having an adjustable restraint which holds the weight in a circular configuration about the distal end of a limb. An anchoring structure, in the form of a sock, shoe or glove, is also provided, and functions to keep the weight in place at the end of the limb. Several structures are disclosed which function as means of attachment, connecting the anchoring structure to the limb encircling weight. One version of the invention provides an ankle encircling weight unit with a strip of each sex of VELCRO lengthwise along its lower portion and tabs with shoe lace holes at each end of the unit. A strip of VELCRO provides similar strips of each sex of VELCRO and is adhered to the collar of the shoe. The strip folds from a first position whereby the strips are engaged by each other, to a second position where the strips engage the strips on the ankle encircling weight unit. The user then laces the shoe's existing shoe laces through the lace holes on the tabs and secures the unit in place.

Method and apparatus for detipping loose cigarettes

Cigarettes are detipped at high speed without degradation of the tobacco in the tobacco rod and regardless of the initial orientation of the filter tip and the tobacco rod in the apparatus. Cigarettes are fed onto a conveyor belt (13) so that they are travelling in a direction perpendicular to their longitudinal axis. A rolling belt (15) disposed above the conveyor belt straightens bent cigarettes and rolls uneven cigarettes. The cigarettes are then fed onto a fluted rotating drum (20) and aligned on the drum by means of an optical sensor (21) and an air jet (25) so that the filter tip portion of each cigarette is adjacent either side of the drum. Rotating knives (23) are properly oriented so that they engage the cigarettes only at the point where the filter tip is connected to the tobacco rod and cut the filters from the cigarettes.

Device and method for treatment of infections

A packing material for the treatment of infections, particularly of the teeth and gums. A biocompatible, polymeric carrier material, typically calcium alginate, has dispersed therein an antibiotic ester which typically defines at least one ester group of 10 to 18 carbon atoms per molecule. The antibiotic ester is present in the polymeric carrier in an initial concentration sufficient to allow the continuous, controlled release of at least an inhibitory concentration of free antibiotic as a hydrolysis product from the antibiotic ester. The rate of release of free antibiotic is influenced by the presence of bacterial lipase, so that a higher concentration of infectious bacteria causes the release of higher concentrations of free antibiotic, hydrolyzed from the ester, in a feedback loop.
