Abstract: 936,005. Tractor-trailer brakes. E. J. J. VAN RILLAER. Jan. 13, 1960 [Jan. 24, 1959], No. 1200/60. Class 103 (1). A trailer over-run brake mechanism comprises a master cylinder 1 fixed to. a housing 28 to which is fixed a sleeve 29 slidable on a sleeve 22, the sleeves 22, 29 being attached to a tractor and a trailer vehicle respectively. A spring 36 between a nut 26 on sleeve 22 and a part 30 fixed to sleeve 29 biases the sleeves apart until a buffer 24 supported on sleeve 22 by nut 23 engages housing 28. A rod 13, slidable in sleeve 22 is connected by an adjustable screw 10 and nuts 9 to the rod 7 of master cylinder piston 6. A pre-compressed spring 19 acts between sleeve 22 and a collar 14 on rod 13 to move piston 6 to apply the trailer brakes but is maintained compressed by a cable 16 fixed to rod 13 and in a slot 42 in hand lever 40, 41 pivoted to a square section end-piece 27 of sleeve 22, the arm 41 of the lever being connected to the tractor by a cable 43. On over-running of the trailer, members 28, 29, 30 welded together and attached to the trailer, move relative to sleeve 22 compressing spring 36 and moving rod 13 and piston 6 to apply the brakes. As soon as the trailer begins to drag, the spring 36 returns the apparatus to the release position, shown in Fig. 1. To apply the trailer brakes, when the trailer is disconnected from the tractor, lever 40, 41 is rotated to permit spring 19 to move piston 6, the spring 19 being pre-compressed to produce a pressure of 170-200 kg/cm.<SP>2</SP> in master cylinder 1. The lever 40, 41 is also rotated by cable 43 on accidental separation of the vehicles. To enable the tractor-trailer combination to be reversed without producing brake application, a valve 4 is opened, from the driver's position, to release any pressure created in master cylinder 1 to reservoir 2. The operative length of rods 7 and 10 and the tension of spring 19 are adjusted by nuts 9 and 23 respectively, through a slot 32 in housing 28 normally closed by a plate 33. Specification 394,323 is referred to.

Title: Polyurethane foams
IPC: C08J9/14
Filed: 1971-01-12
Abstract: 1328953 Polyurethane foam IMPERIAL CHEMICAL INDUSTRIES Ltd 12 Jan 1971 [21 Jan 1970] 1476/71 Heading C3R Polyurethane foam is prepared by first forming a reaction mixture of organic polyisocyanate, organic polyol and an inert blowing agent having a b.p. not exceeding 50‹ C. at atmospheric pressure. The mixture is maintained under such a pressure that the blowing agent is substantially liquid; the pressure is then released when the mixture expands to form a froth which subsequently cures to form a foam. The reaction mixture is brought to such a temperature, either before or during the release of pressure, that the rate of generation of reaction heat in the froth during the curing period is substantially equal to the rate at which heat is dissipated from the froth to its surroundings. Suitable polyisocyanates are tolylene diisocyanate and crude diphenylmethane diisocyanate. The blowing agent may be CF 2 Cl 2  or CF.Cl 3  or a mixture thereof. The polyisocyanate and polyol may be allowed to react together to some extent to form a "quasiprepolymer" before the pressure on the reaction mixture is released. The froth may be formed in a mould so as to fill the mould after which the mould outlet is closed and a further quantity of froth is introduced so as to produce a foam having a dense integral skin.

Title: Improvements relating to the recording and reproduction of colour television signals
IPC: H04N5/95
Filed: 1960-01-15
Abstract: 916,806. Automatic phase control systems. MINNESOTA MINING & MANUFACTURING CO. Jan. 15, 1960 [Jan. 19, 1959], No. 1624/60. Class 40 (5). [Also in Group XXXVIII] In playing back colour television signals recorded on magnetic tape as a carrier frequency modulated by a colour subcarrier the transverse scanning of the tape is automatically controlled in phase, i.e. timing, by comparing the phase of the colour reference burst of subcarrier played back with that of a stable oscillator in a phase detector whose output advances or retards the timing of the scan to compensate for variations in the transverse position of the tape relative to the play-back head resulting in spurious phase modulation of the recorded carrier played back. Colour carrier signals from a magnetostrictive play-back head 11 are amplified and passed to a subtracting circuit 68 also connected through potentiometer attenuators 70, 71 to two delay circuits 66, 67, each delaying the signal by the time of transversely scanning one track of the magnetic tape to free the output from cross-talk with the preceding and subsequent scanned track. The 10 Mc/s. carrier output is then limited at 74 and frequency demodulated at 75 to produce through a filter 76 the video colour subcarrier. The subcarrier colour reference burst is gated at 79, by a pulse from a line sync pulse source 80 delayed by the same amount as at 66, 67, to a phase detector 85 energized also from the reference oscillator 86, whose output variably controls a delay circuit 88 to correspondingly vary the phase (i.e. timing) of the tape scanning by the pulse source 80 to compensate any transverse speed of movement of the tape. The pulse source 80 is multiplied in frequency by six at 89, since six transverse tracks are recorded on the tape for each horizontal line of the picture. The piezo-electric, magnetostrictive head 11 may be of the type described in Specification 908,707. Specification 916,807 also is referred to.

Abstract: 450,603. Motor vehicles ; driving-gear. SMITH, S., Dingley Dell Farm, Windlesham Road, Chobham, Surrey. Jan. 18, 1935, No. 1695. [Classes 79 (ii), 79 (iii), and 79 (v)] [See also Group XXVII] Vehicle driving means of the kind in which change-speed gearing is mounted immediately below or at the base of the engine unit comprises a pair of transmission shaft housings 61 secured one to each side of the engine unit, transmission shafts 57 within the housings and driving the road wheels, and suspension means for the said road wheels mounted on or carried by the housings 61. The engine unit may be at the front or rear of the vehicle, the driving road wheels in the former case being steering wheels. In the construction shown, the engine crank-shaft 10 drives the main shaft 33 of the change-speed gear through a clutch 15 and chain or speed gear 30, 32. The layshaft 37 of the gear is at the same level as the shaft 33 and both shafts are preferably in the engine crank-case so that the same oil is used for lubricating the engine and gearing. The direction of rotation of the shafts 33, 37 is preferably such that their upper parts rotate away from each other so that grit falling on the gear teeth tends to be thrown outward and oil tends to be drawn in between the gear wheels. The final driven shaft 44 of the change speed gear drives the universally jointed transmission shafts 57 through bevel or worm gear 56 and differential gear 58. The shafts 37, 44 are arranged one on either side of the vertical plane of the crank-shaft 10 so that these shafts can be brought close to the crank-shaft without the bevel wheel 56 fouling the latter. The change-speed gear may be in a compartment separate from the crank-case or separated therefrom by a perforated partition. The driving wheels 59 are steerable on steering pivots 63 in the housings 61 and are independently-sprung by means of springs 64. The rear end of the engine unit is connected by stays 68 to the housings 61 and is supported on a transverse member 70 by a rubber mounting 72 comprising a rubber ring or a ring of rubber balls 71. The member 70 is connected at its ends by elastic joints comprising rubber balls 73 to main suspensions arms 65 which are connected by rubber bushes 67 to the housings 61 and are connected to the vehicle body by flexible or resilient connections 66 as described in Specification 412,203. The engine may be mainly behind or in front of either the front or the rear axle. The vehicle suspension may be of the laminated spring or coil spring types. The steering column 73 is supported in part by the member 70 by means of rubber balls 76 mounted between part-spherical cups on the column and the member 70. Specification 412,195 also is referred to.
