Patent GB-2052992-A (GB)
Title: A device for use as an aid to loading a hypodermic syringe
IPC: A61J1/00
Filed: 1979-07-13
Abstract: A device for assisting blind or partially blind diabetics to load a hypodermic syringe with insulin comprises an annular guide member 24. The member 24 has a frusto-conical internal surface 26, which converges smoothly from a relatively large inlet 28 for receiving the needle of the syringe to a relatively smaller outlet 30. A part- cylindrical resilient skirt member 36 projects coaxially downwardly from the periphery of the member 24, and is adapted to fit over and coaxially surround a typical cylindrical insulin bottle, thereby locating the member 24 such that the outlet 30 is close to and aligned with the entry into the bottle. The guide member 24 thus guides the needle into the entry of the bottle. <IMAGE>

Title: Method and apparatus for straightening plate pallets
IPC: B21D1/00
Filed: 1980-01-24
Abstract: The method includes contacting the substantially concave surface of the plate (37) by at least one hard element (11), the or each element being so shaped as to have a small area of contact with said surface, applying, via said contact area or areas, a controlled force to this surface to at least exceed the elastic limit of the plate material at or near said surface, and traversing the element or elements in a controlled manner to bring it or them in contact with at least a selected part of said surface. <IMAGE>

Title: Fuel Pumping Apparatus
IPC: F02M59/10
Filed: 1980-04-23
Abstract: A fuel pumping apparatus for supplying fuel to an injection nozzle 17 of an internal combustion engine comprises a pumping plunger 23 housed in a bore and a piston 24 connected to the plunger. Valve means constituted by a pair of sleeves 25, 26 is provided to control the application of fuel under pressure to the one or other side of the piston. The sleeve 25 is movable and is connected to the output member 33 of an electrically controlled actuating means 27. A spring 35 is interposed between the piston 24 and the output member 33 so that during the return movement of the piston and plunger following delivery of fuel an increasing force will be applied by the spring 35 to the output member to move the output member and sleeve in a direction to cut off the application of pressure to the piston. The final position of the piston and plunger will therefore depend on the force exerted by the actuating means which is a function of the magnitude of the electric current flowing therein. <IMAGE>

Title: Small scale chlorine dioxide plant
IPC: C01B11/02
Filed: 1980-05-29
Abstract: Chlorine dioxide solution for use in waste water treatment is produced in an automated small scale plant wherein sodium chlorate solution is reacted with sulphur dioxide at subatmospheric pressure by countercurrent flow in a reaction tower. Water ejectors are used to withdraw gaseous chlorine dioxide from the upper end of the tower and form therefrom chlorine dioxide solution and also to withdraw liquid effluent from the bottom of the tower for discharge. The plant is fully automated to form chlorine dioxide solution in response to inventory requirements. The chlorine dioxide-producing reaction is only permitted to operate if each of a plurality of sensed parameters is within predetermined ranges.

Title: Balancing Reciprocating-piston Mechanisms
IPC: F02B75/18
Filed: 1980-12-04
Abstract: A two cylinder reciprocating piston mechanism is balanced by three meshing gear-wheels 10, 12 and 14, each of which carries a balance weight 11, 13 and 15 respectively.

Patent GB-2064914-A (GB)
Title: Method of impressing and reading out a surface charge on a multilayered detector structure
IPC: H01L31/06
Filed: 1980-05-14
Abstract: A latent charge image is recorded on and reproduced from a multilayered detector (10) by first providing the detector (10) with a uniform surface charge on its photoconductive layer (16). The photoconductive layer (16) is then biased with an electric field whose polarity opposes that of the uniform surface charge and then the detector is exposed to a modulated radiation flux to cause at least partial discharge of the photoconductive layer (16). The latent charge image of the modulated radiation flux is thus stored and later read by scanning the surface of the photoconductive layer (16) with a small diameter photon beam to further sequentially discharge the photoconductive layer (16) and the changing electrical potential of this sequential further discharge is detected and processed into a video signal by a processor (106) for storage or display.

Title: Amino-polyamides and derivatives thereof useful as plastisol adhesion improvers
IPC: C08G69/26
Filed: 1981-03-25
Abstract: 1 to 2 equivalents of polyamines H2N(CH2)x-(NH(CH2)g)n-NH2, wherein x, g and n are each independently at least 2, are homo- or co-polymerised with (a) 1 to 0.5 equivalents of dicarboxylic acids and (b) 0 to 0.5 equivalents of polymeric fat acids.
