Title: A Rack and Pinion Assembly
IPC: F16H55/28
Filed: 1979-01-15
Abstract: In a rack and pinion assembly in which a rack bar (1) is longitudinally displaceable through a housing (2) by rotation of a pinion (4) engaging with the rack (3), the rack bar (1) is supported in engagement with the pinion (4) by a plastics moulded bearing member (7) having a saddle- shaped bearing part (9) and a tubular retaining part (8) which is displaced longitudinally from the part (9). The bearing part (9) is of saddle-shape to straddle the rack bar (1) opposite to the region of engagement between the rack and pinion teeth and has a resilient bearing surface which biases the rack bar laterally into engagement with the pinion. The straddling portions of the saddle-shape restrain the rack bar from displacement in the direction of the pinion axis (4a). The retaining part (8) locates the bearing member (7) in the housing (2) and restrains that member from rotation (by keying engagement between rib (11) and channel (12)) and from longitudinal displacement by its co- operation in an annular recess (15). <IMAGE>

Patent GB-2033964-A (GB)
Title: Ejector
IPC: G01F1/44
Filed: 1979-05-16
Abstract: An ejector has a bore 54 which is reduced to bore 50 at an internal shoulder 48. A drawn tapered eyelet 44 is mounted in the larger bore 54 with its small end at or near the reduced bore 52 and forms an inducing fluid nozzle. The small end of the tapered eyelet is smaller than the reduced bore 50 so the high velocity flow leaving the tapered eyelet develops a reduced pressure in the annular space 52 which may be sensed or utilized through the tube coupling 56. Inducing fluid flow is controllable by a solenoid actuated valve 18, 24. <IMAGE>

Title: Continuous Cyanoethylation Process
IPC: C07C253/00
Filed: 1979-06-15
Abstract: A continuous homogeneous cyanoethylation process, in which acrylonitrile is reacted with a compound containing a labile hydrogen atom to form a  beta - substituted propionitrile derivative and in which the reaction zone is maintained at a cyanoethylation temperature, is characterised in that a relatively large amount of reactor effluent, i.e. 50-90 wt. %, is recycled to the reactor.

Patent GB-813212-A (GB)
IPC: C08G63/672
Abstract: 813,212. Linear copolyesters. DU PONT DE NEMOURS & CO., E. I. Dee. 11, 1956 [Dec. 15, 1955], No. 37878/56. Class 2 (5). [Also in Group VIII]  A linear copolyester is derived from a glycol of formula HO(CH 2 ) n OH, where n is 2-6, terephthalic acid, isophthalic acid and at least one pair of acyclic dicarboxylic in the molar ratio 0.5 to 2.0 and each having the formula HOOC-CH 2 -X-CH 2 -COOH where X is a divalent radical containing in the chain of atoms linking the two -CH 2 -COOH groups 2 to 8 atoms of which not more than 2 atoms are oxygen atoms and the rest are hydrocarbon carbon atoms and having from 0 to 3 hydrocarbon carbon atoms in side-chain substituents, the acyclic dicarboxylic acids of said pair (or each pair if there be more than one) differing from one another by at least 3 atoms in the chain of atoms linking the -CH 2 -COOH groups, the molar proportions of the acid components of said copolyester being within the following ranges: terephthalic acid 20 to 60 per cent, isophthalic acid 15 to 50 per cent and acyclic dicarboxylic acids 10 to 50 per cent. The copolyesters are made by the melt polymerization of a mixture of bis-(hydroxyalkyl esters of the acids. They are used as adhesives for joining a lamina of a polyalkylene terephthalate to another lamina (see Group VIII) or as a binding agent for a mat of non-woven fibres or as an adhesive for replacing solder in fabricating metal containers. To this end they may be used dissolved in a solvent (e.g. butyrolactone, benzyl alcohol, dimethyl sulphoxide, dioxane, dimethyl formamide, diacetone alcohol, chloroform, cyclohexane, methyl ethyl ketone preferably in admixture with toluene or dioxane, methylene chloride, nitromethane, tetrahydrofurane, toluene or carbitol acetate) or admixed with a plasticizer (e.g. chlorinated diphenyl or an alkyl or aryl phosphate). In examples copolyesters were prepared by polycondensing the bis-(hydroxyethyl) esters of terephthalic, isophthalic, adipic and sebacic acids in presence of ethylene glycol and antimony oxide; the bis-(hydroxyethyl) esters of terephthalic, isophthalic and sebacic  acids being prepared by reacting the dimethyl esters of the acids with ethylene glycol in presence of calcium acetate and the bis-(hydroxyethyl) ester of adipic acid being prepared by reacting the free acid with ethylene glycol. Specification 578,079, [Group IV], is referred to.
Patent GB-2091978-A (GB)
Title: Bias control for an image display device
IPC: H04N9/72
Filed: 1982-01-25
Abstract: To control the blanking (black) current level of a TV CRT (15), an output signal (CP) proportional to the cathode current is developed during monitoring intervals with no image displayed, e.g. after vertical retrace, in response to a grid pulse (GP). The cathode signal is processed by a digital network (22) to produce incremental bias steps for modifying the cathode bias, towards the desired cathode black current level. In the network, the signal (CP) is compared with a reference level which should lie within the noise band of the signal (CP), the comparator producing a random sequence of digital signals; but the level lying above or below the noise band when the signal is incorrect produces one of two digital signals. The network (22) under the random sequence does not change the bias but on receiving one of the digital signals in the absence of the random sequence it produces positive or negative increments. A special form of grid drive pulse prevents "hunting". In a 3-gun colour system, each cathode has its own circuit (14a, b, c), the grid 18 being common. <IMAGE>
