Abstract: 1,157,741. Preparation of aminomethylenemalononitrile. F. HOFFMANN-LA ROCHE & CO. A.G. 21 Sept., 1966 [24 Sept., 1965], No. 42125/66. Heading C2C. Aminomethylene-malononitrile is obtained by condensing formamidine or a salt thereof with malononitrile. The reaction is suitably effected in the presence of a weak base condensing agent and an inert organic solvent, preferably an alcohol, at 10-30 C., and the formamidine salt employed as starting material may be a salt with a mineral or organic acid. The reaction may also be effected by reacting a formamidine salt with a cation-exchange resin and treating the resulting formamidine resin salt with malononitrile thereby condensing the formamidine with the malononitrile and removing the condensate from the resin; the resinous material employed as the cation-exchange resin suitably contains acidic groups such as sulphonic groups and any insoluble sulphonated polymerizate of a poly-vinyl-aryl compound may be used. The resin employed is preferably of the styrene- (divinyl-benzene) type characterized by the presence of sulphonic acid groups.

The device preferably comprises a pneumatic circuit 1, Fig. 2, driving a piston 7 which is connected to the headlamps 8 through a compressed spring 19 and a rod 22, and the means are adapted to release the spring in response to loss of pressure in the circuit. The means include an electrical circuit 11 comprising a first switch 13 closed by variations in the vehicle trim and a second switch 14 closed by loss of pressure in the circuit 1. The spring 19 is compressed between abutment members 20, 21 which may be held together by a fusible link (100, Figs. 4 and 5, not shown) adapted to melt when current flows in the circuit 11. In an alternative arrangement, Fig. 7, the abutment members are interconnected by a bimetallic element 200, 202 which normally engages in slots 204 in the member 21 but expands when current flows in the circuit 11 thereby releasing the member 21 and permitting the spring 19 to expand. When the circuit 11 is de-energized the element can be re-engaged with the slots by pushing the abutment members towards one another to re-load the spring.

Abstract: 940,443. Transistors. MULLARD Ltd. Dec. 14, 1959, No. 42433/59. Heading H1K. [Also in Division G1] In the manufacture of a transistor such as described in Specification 911,292, in which recrystallized semi-conductor regions 2, 4, Fig. 1, underlie metallically conductive resolidified alloy regions 1, 3, etching is continued in successive steps to the line 20a to undercut the resolidified regions until the area of contact between the recrystallized and resolidified regions is reduced to not more than one half of the original area of contact, preferably not more than one quarter, in order to reduce the inter-electrode capacitance. During etching the slot 12 between the two alloy regions is protected by polystyrene lacquer 13 applied as a solution in ethyhnethylketone. The lacquer 13 is then removed, the whole body etched and the regions 1, 3 covered in polystyrene lacquer 14 which penetrates to the undercut areas. Cerric black resist in acetone may be used instead of polystyrene in ethylmethyl ketone. Nickel wires 9, 10 soldered to the regions 1, 3 form the base and emitter connections. Nickel wire 11 forms a connection to the resolidified and recrystallized base regions 7, 8. Main body 6 consists of P-type germanium crystal of resistivity 2 ohm-cm., to which is alloyed an alloy of lead and 1 % antimony to form region 1, an alloy of lead, antimony and aluminium to form region 3 and an alloy of indium and gallium to form region 8. Antimony diffuses into the germanium to form an N-type region 5. The transistor produced is encapsulated. An automatic manufacturing procedure is described. The invention may be applied to a transistor in which as described in Specification 906,906, two alloy zones are provided by alloying at two separated areas of a semi-conductor body. In Fig. 7, the portions 40, 41 are removed from the resolidified layers 36, 37, e.g. with a sharp blade, and the connecting wires (not shown) then connected in position. An etch-resistant layer 38 is provided and etching is progressively effected until the full line 39 is reached.

Abstract: 911,448. Reverse gear. PARSONS ENGINEERING CO. Ltd. Oct. 4, 1960 [Dec. 17, 1959], No. 42951/69. Class 80 (2). A bevel epicyclic reversing gear particularly for marine propulsion has a planet carrier 11 stationed by a hydraulically-operated bandbrake 27 for reverse drive, and clutched to a driving side-wheel 4 for forward drive by a centrifugally-operated multi-plate clutch 14. Centrifugal levers 17 are pivoted to the planet carrier and actuate the clutch through push-rods 19. On starting, with the driven side-wheel 3 stationary and the clutch 14 disengaged, the planet carrier 11 is driven at half the speed of the driving-shaft 5 which is speeded up until the clutch engages. This causes the planet carrier to rotate at the input speed, thus ensuring rapid full engagement of the clutch. Disengagement occurs when the input speed is half the engagement speed. The control lever controlling the application of the reverse brake 27 may also control a driving engine, movement of the lever in one direction from neutral merely opening the engine throttle, movement in the other direction first actuating a valve to apply the brake and then opening the throttle. The clutch 14 may be put out of action by sliding a collar 24 to the right so that the ends 21 of the centrifugal levers 17 are held by a groove in the collar and the clutch remains disengaged so that the engine can be run at high speed without moving the boat.

Heading F2E. An internal shoe drum brake for a heavy motor vehicle is adapted to exhibit the characteristic of a " duo-duplex brake," i.e. one in which the shoes are anchored at either end according to the direction of rotation to give two-leading shoe brake in both directions, when hydraulically applied, and to operate as a "duo-servo" brake, i.e. with both shoes floating and anchoring one on the other, when mechanically applied, so that less manual force is required to operate the handbrake of the vehicle than is the case when a conventional " duo-duplex brake " is used, this result being obtained by arranging between the non- actuated shoe ends of a duo-servo type brake a transmission arrangement which comprises a lever engaged between the shoes and between a pair of cup spring assemblies which are also acted on by an hydraulic device arranged, when the brake is applied hydraulically, to pre-stress the cup springs, to apply a damping force to movement of the shoes. As shown, a pair of shoes 2, 3 are arranged within a drum 1 in association with an actuating cylinder 4 and a transmission arrangement comprising plungers 5, which incorporate slack-adjusters (Fig. 2, not shown) arranged between the non-actuated shoe ends for sliding in a fixed bush 6, a lever 9 having one end 9a located between the plungers and engageable with the sleeve 6 after an initial clearance 10 has been taken up, the other end 9b being located in a slot in a pin 12 slidable in pistons 13 against the centralizing force of cup springs 11, and cylinders 14 in which the pistons 13 operate, the chambers 15 being connected by a line 16 to the chamber of cylinder 4. In hydraulic operation the cup springs 11 are pre-stressed so that a damping force is applied to resist movement of the lower ends of the shoes and thereby reduce the force transmitted from one shoe to the other, so that the arrangement acts as a resilient anchor for these shoe ends with limited transmission of the drag force from the primary shoe to the secondary shoe. When the brake is manually applied, as by a lever and linkage 8 the cup springs 11 are not stressed, so that the end 9b of the lever 9 is free to move and substantially the whole of the drag force of the primary shoe is transmitted to the secondary shoe. Springs 17 ensure that the lever 9 is centralized after a manual application of the brake.

In a recirculating data store, positive and negative portions of a clock signal respectively gate alternate data units in the store to one feedback loop and the other data units to a second feedback loop. Two trains of data in 8421-coded-decimal form are interleaved at bit level in a delay line and recirculated to the delay line input via respective feedback loops each including three latches and one including a serial full-adder-subtractor. The adder-subtractor also receives a data input from elswhere. Each decimal digit is followed by a two-bit gap in each train, and when the feedback loops hold such gaps presence of an "exchange" command will alter the phase of gating signals which route the bits to the appropriate feedback loops, so that the train which previously used one loop will now use the other and vice-versa.
