Title: Actuator with a torque limiting device
IPC: F15B15/12
Filed: 1973-02-20
Abstract: 1448224 Automatic torque-dependent brakes; full-face disc brakes LUCAS INDUSTRIES Ltd 28 Jan 1974 [20 Feb 1973] 8210/73 Heading F2E A rotary actuator comprises a housing, a drive shaft 11 and a coaxial output shaft 18 both journalled in the housing, a coaxial coupling member 17 movable axially of the drive and output shafts, a reduction gear train 16 connecting the drive shaft 11 to the coupling member 17, coupling means 21 &c. between the coupling member 17 and the output shaft 18 arranged to transmit power from the coupling member to the output shaft and to cause axial displacement of the coupling member when the torque transmitted through the coupling means exceeds a predetermined value, and a brake 23 on the drive shaft 11 arranged to be actuated by such axial displacement of the coupling member 17. Preferably the brake comprises interleaved sets of rotor and stator plates 24, 26, respectively, located between an abutment on a fixed member 27, to which the stator plates are splined, and a thrust bearing 28 adjacent one end of the coupling member 17. The coupling member 17 is slidable relative to the final gear of train 16 and is urged to the right by an assembly of spring washers 22 located between a flange on a spigot part 19 of the output shaft 18 and an internal shoulder on coupling member 17. Balls 21 are thereby normally retained each between a V-notch in the right-hand end of member 17 and a corresponding V-notch in the left-hand end of the (remaining) tubular part 20 of output shaft 18. In operation, power from an air motor 10 can be transmitted via gear train 16 and coupling member 17 to output shaft 18 when the torque load on shaft 18 is below a predetermined value. When this value is exceeded, the balls 21 are forced to ride up the V-notches, forcing member 17 leftwards to actuate brake 23.

Title: A method of producing gold-silicon alloy contacts
IPC: H01L21/00
Filed: 1960-03-09
Abstract: In a method of forming a gold alloy contact on silicon, the latter is heated to a temperature between 150 DEG  C. and the eutectic point of the silicon-gold alloy system, coated under vacuum with gold, which may contain up to 15% of germanium, and then slowly cooled to room temperature, e.g. over at least 15 minutes.  The final alloy may contain an activator from Group III or V of the Periodic Table, particularly antimony or aluminium, and is produced by heating the coated silicon in contact with aluminium or with a gold-antimony alloy to 400-800 DEG  C. in an inert atmosphere.

Patent GB-684699-A (GB)
Title: Improvements in the production of linear polyhydrazides
IPC: C08G73/08
Filed: 1950-04-06
Abstract: Linear polyhydrazides suitable for films, foils, filaments and fibres are prepared by reacting a dicarboxylic acid or ester, acid halide or anhydride thereof with a dihydrazide of a dicarboxylic acid, preferably in an inert and neutral solvent such as nitrobenzene, the xylenols and cresols, o- and p-dichlorobenzene and nitroparaffins. For high molecular weight substantially equimolecular quantities are used.  The acid may be in slight excess, e.g. 5 per cent by weight, to ensure a heat-stable product.  Specified acids are (i) straight chain: oxalic, malonic, succinic, glutaric, adipic, pimelic suberic, azelaic, sebacic; (ii) branched chain: a -methyl adipic, b -methyl adipic, a ,b -dimethyl adipic, iso-pimelic (2-methyl-a -ethyl succinic); (iii) cyclic: cyclo-hexane dicarboxylic acids; cyclo-hexene dicarboxylic acids, cyclohexane diacetic acids, phthalic, iso-phthalic and terephthalic acids and phenylene diacetic acids. Simple hydrazides of dicarboxylic acids may be employed or N-alkyl substituted dihydrazides of dicarboxylic acids provided each nitrogen atom retains a reactive hydrogen atom.  The dihydrazides may be prepared by reacting a diester of the acid with hydrazine or an alkyl hydrazine; e.g. adipic ester and methyl hydrazine gives N,N1-dimethyl adipic dihydrazide.  Examples are given of the preparation of polymers from equimolecular proportions of reactants selected from those listed.

Abstract: 1377462 Toy gramophone VICMA SA 22 Feb 1973 [5 Dec 1972] 8783/73 Heading G5R In a toy gramophone in which a stylus 8 is mounted on a pick-up arm 12, having a part contacting a plate 4 on a resilient diaphragm speaker, and reproduces sound from a record 6 when this is driven from motor shaft 1, a gear arrangement is provided for repeat play of the record. The record disc rotates on a fixed shaft and is supported on a spring 5. An axial extension of the record disc is secured to a coaxial gear 10 having 18 teeth and this is coupled by pinion 3 to a second coaxial gear 11 having 19 teeth which is free to rotate on the fixed shaft. The coaxial gears thus rotate in the same direction but at different speeds and each carries a projection on its face directed towards the other gear. As these engage the lower gear and hence the record disc are momentarily moved downwardly against the action of spring 5 and during this period the pick-up arm is freed to move under the action of spring 7 to a start position on the record defined by stop 9.
