Patent GB-1257784-A (GB)
IPC: B60T8/52
Filed: 1968-11-15
Abstract: 1,257,784. Antiskid braking systems. DEFENCE, SECRETARY OF STATE FOR. 13 Feb., 1970 [15 Nov., 1968; 12 Sept., 1969], Nos. 54416/68 and 45141/69. Headings F2E and F2F. In a vehicle braking system comprising a brake shoe carrier or back plate 2, the plate 2 is mounted for limited rotation relative to the vehicle chassis and during braking a torque opposed to that applied by the braking force in conjunction with adhesion between the road wheel and ground is applied to the back plate to rotate it when the reaction is reduced due to loss of adhesion by the incidence of slip and on said rotation braking force is reduced to restore adhesion between the road wheel and the ground. In one form of the invention for use with a mechanical braking system, the opposed torque is supplied by a spring 6 acting, in a cylinder 5 secured to the axle casing, on a piston 4, the rod 3 of which engages an arm 1 secured to the back plate 2, the piston-rod 3 extending through the cylinder 5 and carrying a bearing member 7 in which is formed an arcuate slot 8 centred about an axis 9 of a bell-crank lever 10, one arm 10a of which is forked and has formed therein slots 11. A pin 12 mounted in slot 8 extends through slots 11 and has pivoted thereto the yoke 13 of a pull rod 14 connected to a brake shoe operating lever 15, the second arm 10b of lever 10 being connected to a linkage 17 actuated by a brake pedal. In operation the movement of plate 2 varies the mechanical advantage of the system by causing pin 12 to slide relatively to the axis 9 of lever 10. In a second embodiment, for an hydraulic brake system, the wheel cylinder is connected by a flexible pipe 26 to the pressure chamber 24 of an auxiliary cylinder 25 in which a piston 27 can slide to vary the volume of the chamber 24 and has a rod 31 engaging an arm la secured to the back plate 2a. Extending radially from cylinder 25 is a smaller valve cylinder 36 across the end of which extends a guide tube 42 for a plunger 43 forming a valve detent, the piston 27 and plunger 43 being interconnected by a lever 46 pivoted at 47. When the brakes are applied and slip occurs, piston 27 is moved against the reduced reaction of the back plate 2a to compress a spring 29, move plunger 43 under the influence of lever 46 to bring a notch 45 into register with a ball 44 and allow a valve orifice 37 to be opened so that brake fluid flowing into chamber 36 releases braking pressure. In an embodiment intended for a pneumatic braking system, the rod 96 of a piston 68 operates a toggle device to close an inlet valve 85 and open an exhaust valve 86.

Abstract: 1,258,417. Obtaining oxygen-rich gas from air. T. TAMURA. 30 Dec., 1968 [27 Dec., 1967], No. 61745/68. Heading B1L. A cyclic process for obtaining oxygen-rich gas from air employs pretreatment columns 2, 3 packed with an adsorbent having a higher adsorption power for carbon dioxide and water than for oxygen and nitrogen, e.g. silica gel and alumina, and column 1 packed with an adsorbent having a higher adsorption power for nitrogen than for oxygen, e.g. a Type 5A or 13X molecular sieve or one of two specified natural tuffs from Japan. Initially, with valves 5, 6', 7', 9, 10 and 11 closed and valves 6, 7 and 8 open, the beds 1, 2 are desorbed or adsorbed gases from the previous cycle by evacuation through line 12. Valve 8 is then closed, valve 5 opened, and dry,- high purity oxygen introduced by line 13 until normal adsorption pressure is reached; the oxygen so introduced may be product gas or pure oxygen. Valve 9 is then opened, introduction of oxygen through line 13 stopped, and air introduced through line 14. Carbon dioxide and water are adsorbed in pretreatment column 2, and the purified air stream, with displaced oxygen, then passed through column 1 where nitrogen is preferentially adsorbed, oxygen-rich gas leaving through line 13. When adsorbent in pretreatment column 2 is exhausted, column 3 is brought on-stream, by opening valves 6', 7'. Valves 6, 7 are closed, valves 10, 11 opened, heater 4 actuated and a stream of air passed through the column to desorb it. In a preferred embodiment (see Fig. 2, not shown), continuous cyclic operation is achieved using a battery of three such units.

Abstract: 1,258,602. Signalling apparatus. HONEYWELL Inc. 29 Jan., 1969 [29 Jan., 1968], No. 5007/69. Heading G4F. A sonar communication system, e.g. for communicating between a central station and a plurality of submerged stations, utilizes combined spaced-diversity and frequency-diversity reception.  Remote station.-The power supply at a remote station is switched on by transmitting from the central station an alert tone (unique to each remote station) which is received by transducer 60 and/or 72 the outputs of which are passed via amplifiers and frequency converters 62, ... 78 to alert tone detectors 64, 84 which turn on the power for the rest of the remote station. Binary frequency-shift-keyed signals at two different pairs of frequencies are next transmitted by the central station and received by spaced transducers 60, 72. The individual frequencies are selected by detectors 80, 82, 68, 70 and fed to a combiner 90, arranged to select the most favourable signal or combinations of signals. After decoding at 92, the signals are arranged to select required binary and incremental functions (e.g. adjustment of a diaphragm). After a period determined by timing generator 94, sensors and limit switches appropriate to the selected functions (e.g. temperature or size) are connected to a status encoder 104 which is coupled to modulators 106, 108 which in turn, provide a frequency-shift keyed signal, indicative of the values measured by the sensors and settings of limit switches, for transmission by details 112, 74, 72, back to the central station. Central station.-Fig. 1 (not shown) relates to the central station which comprises a frequency. shift transmitter (similar to blocks 104 ... 112, 74, 72 and a spaced-diversity receiver, all similar  to that shown in Fig. 2. The central station also includes an operator control system and display panel. Error-correcting codes may be employed.

In a circuit for splitting an input signal into two frequency bands, e.g. for separating the chrominance and brightness components of a colour television signal, the signal is fed via an amplifier to the inputs of two complementary filters, to pass the respective bands, and the outputs of the filters are summed to derive a negative feedback signal for the amplifier. As shown, the video signal is applied via amplifying transistors 1316, 1322 to emitter follower transistor 1330, feeding filters 1370, tuned to reject the chrominance signal, and 1346, tuned to accept the chrominance signal. The filters feed the chrominance and brightness components via respective emitter followers 1362, 1382, to the outputs and also to a resistive mixer 1370, 1390 from which the combined signal is fed back, as negative feedback, to the input stage of the amplifier 1316.

Abstract: 1,266,054. Heat-insulating slabs. FOSECO TRADING A.G. 3 March, 1970 [14 March, 1969], No. 13653/69. Addition to 1,080,647. Heading C3N. [Also in Division D2] A slab of heat insulating composition comprises, by weight, 1-20% cellulosic fibre, 1-20% of a difficultly water-soluble powdered alkali metal silicate which at 17‹ C. has a solubility in water, in one hour, of at most 10% by weight, preferably at most 5%, 0À5-5% of an alkali metal carbonate and a remainder consisting wholly or substantially wholly of granular or a mixture of granular and fibrous refractory, the said fibrous refractory constituting at most 10% by weight of the refractory mixture. The preferred difficultly water-soluble alkali metal silicate is sodium silicate having a ratio of SiO 2  to Na 2 O greater than 2 : 1, e.g. 3À375 : 1. The alkali metal carbonate is preferably sodium carbonate. The composition preferably comprises 4-20% by weight of cellulosic fibre and 4-20 % by weight of the difficultly water-soluble powdered alkali metal silicate. The slabs may be formed by vacuum dewatering through a fine mesh former an aqueous slurry of the solid constituents and thereafter drying the damp slabs. Since the bulk of the slurry liquid is expressed from the solid constituents, it is necessary to employ a relatively high proportion of alkali metal carbonate, e.g. 10-30% by weight, in order to provide in the final slab the required amount of alkali metal carbonate. Specific refractory materials are silica sand, silica flour and amosite asbestos. The cellulosic fibrous material may be waste paper. The slabs may be in the form of a hot top lining slab or a casting riser sleeve.
