Abstract: 1,199,870. Preparation of N-acyl urethanes. FARBWERKE HOECHST A.G. 4 Sept., 1968 [4 Sept., 1967], No. 42155/68. Heading C2C. N-acyl urethanes, e.g. those of the formula wherein R represents an alkyl group containing 1-18 carbon atoms which may be substituted, a C 1-4  alkenyl group, a cycloalkyl, aralkyl or aryl group, or an alkylene group, which may be substituted, R<SP>1</SP> and R<SP>2</SP> each represent a hydrogen atom, an alkyl group or together represent a bivalent aliphatic radical, a is 0 or 1, and n is 1 or 2, are obtained by reacting an organic acid amide containing at least one hydrogen atom linked to an amide nitrogen atom with a trihalogeno acetic acid ester. The compounds of the above formula are obtained by reacting n moles of an organic amide of the formula with (a + 1) moles of a compound of the formula wherein X represents a halogen atom. The reaction is generally effected at a temperature of 0-200‹ C. in the presence of a basic catalyst and optionally in the presence of an organic solvent. The preferred catalysts are tertiary and sterically hindered amines but other compounds possessing basic properties may also be employed.

An electric power track has a casing comprising sections each consisting of parts 1, 2, 3 bolted together, the sections being connected together end-to-end by formers 11, Fig. 3 (not shown). which have spring clips 12 in V- shaped grooves to support V-section conductors 13 which are engaged by contacts 17 of a current collector. The collector comprises a plate 8 having rollers 7 running in tracks 6 formed in parts 2, 3 and is coupled to a moving carriage by a chain 9 or bar and conductor wires 10, Fig. 2. The spring clips 12 have eyes 14 through which bolts 15 pass to connect pairs of clips at a former, where an expansion gap is left between the conductors, to ensure an uninterrupted flow of current. Each contact 17 is fixed in shoe 16, Fig. 2. which is universally momted in an arm 19; the arm 19 is pivoted at 26 to block 27 pivoted at 28 to the plate 8. A spring 25 biases the contact against the condoctor and a spring 29 biases the contact upwardly and subsequently holds the rollers in engagement with the track. The gap between the track parts 2, 3 may be closed by sealing strips which are moved aside by plate 8. The part 1 of the power track casing is removable for maintainance purposes. The contact units C1, C2, C3, C4 are staggered on plate 8 to assist in self-centring of the collector assembly, so that the units are situated at the corners of plate 8 with units C1, C3 above units C2, C4. The conductors may be of figure-of-eight or of a grooved cross-section, Fig. 4 (not shown), and are preferably strained.

Title: Improvements in windscreen wiper control systems.
IPC: B60S1/48
Filed: 1968-09-06
Abstract: 1,217,375. Control of D.C. motors. REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT. 6 Sept., 1968 [18 Sept., 1967], No. 42517/68. Heading H2J. [Also in Division A4] A windscreen wiper system operates differently under the four following conditions:-(1) wet road surface following a severe rainfall, (2) drizzle, (3) rain or snow, (4) sudden shower or heavy rainfall. Under condition (1) if mud is spattered on the windscreen the windscreen washer knob is depressed which also closes bridging contact 29 to bridge contacts 26, 31 which completes a circuit from the positive of the energy source through contact 29 and terminal 22 to the high-speed brush 2 of wiper motor 1 to energize the motor at high speed. When the pressure on the washer knob is released, contact 29 is changed back to bridge contacts 27, 30 which breaks the feed to the highspeed brush. At the same time cam 5 on the motor 1 has changed over contact 6 to contact 9 so a circuit is completed from the positive of the supply to complete the circuit 37, 42, 34, 10, 9, 7, 25, 27, 30, 32, 40, 38, 41, 35, 23 to the lowspeed motor brush 3. The motor therefore operates until the end of the wiper stroke when cam 5 changes over contact 6 to contact 8 to break the motor feed and to short-circuit the motor armature through 18, 15, 13, 8, 6, 7, 25, 27, 30, 32, 40, 38, 35, 23, 3, 4, 24 which brakes the motor 1. Under condition 2 the switch 20 is closed which completes a circuit from the positive of the supply through switch 20 and heater coil 16 to earth. The heater coil heats up and bimetal 14 changes over to contact 11 completing the circuit from the positive through 37, 42, 34, 10, 9, 11, 15, 14, 13, 8, 7, 25, 27, 30, 32, 40, 38, 41, 35, 23, 3, 4, 24 and the motor is energized at low speed. During the wiper stroke contact 6 is changed over by cam 5 to contact contact 9 which completes the motor circuit through contact 6 so that when bimetal 14 cools down and retracts the circuit to the motor is still made until contact 6 is changed back to contact 8 which breaks the motor feed and short-circuits the motor thus braking it. Coil 16 then heats up again and bimetal 14 again changes over to repeat the cycle. Under condition 3 the motor control switch 33 is set to position P, thus establishing a circuit 37, 42, 41, 35, 23, 3, 4 and 24 energizing the motor at low speed until the motor control switch 33 is pushed in again to position A when if the wiper is not at the end of its stroke contact 6 completes the circuit until the end of the stroke is reached when contact 6 changes back to contact 8 breaking the motor feed and shortcircuiting the motor 1. Under condition 4 the high speed of the motor is obtained by setting switch 33 at position G, the circuit then being 37, 42, 43, 36, 22, 2, 4 and 24. The wiper again comes to rest at the end of its stroke after switch 33 is returned to its initial position A. A similar circuit, Fig. 2 (not shown), is also described for a single-speed motor.

Abstract: 1,039,601. Transformers. PLESSEY CO. Ltd. Dec. 12, 1962 [Dec. 6, 1961], No. 43695/61. Heading H1T. A cooling system for electrical equipment using an inert liquid (the vapour of which has a relatively low resistance to breakdown until heated) includes a heater controlled by a temperature-sensitive switch to heat the liquid to a predetermined temperature before the equipment is switched on. The heater may be immersed in the cooling liquid for the equipment, which may be a transformer 1 (the Figure, not shown), or mounted in thermal contact with the outside of the vessel 2 carrying the liquid 3. Provided that the ON/OFF switch at 15 is closed, then the temperature-sensitive switch 16, which may include a thermistor, and is immersed in the liquid, will operate when the required temperature is reached, thus energizing the coil 12A of a changeover switch 12 and transferring the voltage supply connected to wipers 14 from the heaters to the equipment. A second temperature sensitive switch may be incorporated to operate at a higher temperature and to switch on a further cooling system, such as a fan, to blow air along the ducts 9.

The polymer may be a homopolymer selected from the group consisting of polyacrylic acid and salts thereof or may be derived from copolymerizing an alkali-metal acrylate with a different monomer comprising an ethylenically unsaturated polymerizable compound containing a hydrophilic group in a side chain (numerous examples are provided).
