Title: Vaccine applicator
Inventor: PHARAOH JAMES FREDERICK
IPC: A61D1/02
Filed: 1991-12-19
Abstract: A vaccine applicator (1<1>) has a container (2<1>) for containing the vaccine which is able to be transferred by the flexing of a diaphragm (8<1>) to a needle (6<1>) which has caused a scratch on an animal's skin. In applying pressure with the needle (6<1>) on the animal's skin to cause the scratch, the plunger (5<1>) is forced rearwardly within its housing (4<1>) which causes the flexing of the diaphragm (8<1>). Subsequent release of the pressure on the animal's skin provides for the further flexing of the diaphragm (8<1>) and the flow of vaccine through the diaphragm slots (9<1>, 18). An optional sponge member (16) can absorb the vaccine and regulate its flow over the plunger (5<1>) and onto the needle (6<1>). <IMAGE>

Patent GB-2290090-A (GB)
Title: Toilet solution dispenser
Inventor: GRAY DOUGLAS
IPC: E03D9/03
Filed: 1994-06-07
Abstract: The toilet solution dispenser comprises a container (14) of concentrated liquid, a mounting assembly and a suction chamber (5). The suction chamber draws concentrated liquid from the container as the water level in the cistern drops during toilet flushing. As the water level drops to a point just before flushing ends, the liquid mixture in the suction chamber exits and combines with the last portion of water flushing the toilet. This ensures a set amount of liquid concentrate remains in the toilet pan to perform its function every time the toilet is flushed. Water is held in the suction chamber during flushing by the action of a valve at the top of the chamber. As the cistern fills with water so does the suction chamber. The use of an externally visible container indicates when the liquid concentrate needs replenishing. <IMAGE>

Title: Control of a fusion process by determination of specific heat variation
Inventor: KUMAGAI MASARU
IPC: B29C65/34
Filed: 1994-09-26
Abstract: In a method of automatically controlling the fusion process of thermoplastic resin articles a current is fed to a resistor for fusing together the resin surfaces facing one another. Electrical characteristics of the resistor is calculated upon increase of the power to a given level, also calculating specific heat of the resin through ON-OFF control of the resistor. The power is then raised through stages based on the characteristics and the specific heat, to determine variation coefficients of the characteristics and specific heat, at each stage and through further ON-OFF control. The power is stopped as the variation coefficient becomes smaller than a given value, with the ON-OFF control continued until the specific heat becomes equal to or lower than a preset value to cease the power supply. The method may be applied to pipe joints (Figures 2 - 4) or fusible tapes (Figures 5 and 6). <IMAGE>
