Title: Improvements in or relating to electrical signalling systems
IPC: H04Q1/446
Filed: 1931-12-08
Abstract: 393,327. Electric signalling systems. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, TERRONI, T. B. D., 20, Staplands Road, Broadgreen, and TURTON, G. D., 48, Church Road, Stanley, all in Liverpool. Dec. 8, 1931, No. 34053. [Class 40, (i).] In a signalling system employing alternating current of a plurality of different frequencies, the receiver is tuned in turn to the various frequencies and a common responding relay energizes as the circuit is tuned to the various components of the incoming signal and controls the energization of particular relays of a relay group. The tuning of the circuit is effected by a relay chain. When a signal is received over 1, 2, relay X responds and relays A-E energize. When E pulls up it breaks the circuit of A and relays A-E fall away slowly in turn. When A energized the incoming signal was connected to the tuned circuit feeding valve V2 and the tuning of this circuit is altered as each relay of the chain A-E falls away. Assuming the signal contains the third and fourth frequencies of the series, when relay B falls away the tuned circuit responds to the incoming signal and Y operates. Relay C is held energized and relays Z and CC pull up in series, relay CC locking up to x and closing a circuit over, 17. Relay Z shorts out Y and C falls away. The circuit is now tuned to the fourth frequency and Y again energizes, holding D and allowing Z and DD to pull up. DD locks and closes a circuit over 18 and Z releases Y to allow the relay chain to complete its action. The energized relays CC and DD hold up until the received pulse terminates. The valve V3, controlling relay X, may be fed directly from the line circuit and tuning may be effected by a parallel, instead of a series, circuit or by variation of capacity. The relay chain could be replaced by a step-by-step switch.

Title: Improvements in reinforced footwear and method of making same
IPC: B29D35/14
Filed: 1954-11-29
Abstract: 775,500. Moulding footwear. UNITED STATES RUBBER CO. Nov. 29, 1954 [Jan. 4, 1954], No. 34478/54. Class 87(2). [Also in Group VII] Flexible seamless footwear with a reinforced sole is made by a slush moulding method which comprises (i) pouring a resinous plastisol into a metal mould 10 to a depth sufficient to form a reinforcing layer 11 for the sole, (ii) heating the mould, (iii) pouring in additional plastisol to a height sufficient for the completed footwear, (iv) pouring out the plastisol that does not adhere to the mould, (v) heating the mould to fuse the skin of plastisol 14 remaining on the mould wall. In the last step the layers 11 and 14 are fused together to produce a reinforced sole. The method may be modified by heating the mould in the last step to a temperature insufficient to fuse the plastisol but high enough to gell it and then pouring in resinous plastisol which contains a blowing agent. After the excess, which does not adhere to the layers of material already in the mould, has been poured out the mould is heated sufficiently to blow the layer last deposited and thereby produce a celluar lining to the footwear. The heating is continued till the three layers are fused and integrally bonded together. A 'suitable plastisol for the layers 11 and 14 is produced by mixing together (i) a plasticizer comprising dioctyl phthalate. dioctyl adipate and sebacic acid polyester, (ii) an organic cadmium stabilizer, (iii) colouring pigment, and adding to the mixture, with high speed stirring, finely divided polyvinyl resin powder. A suitable temperature for heating the mould to deposit the layer 11 is 200‹F., the molud being in the oven for about 8 minutes. A suitable gelling temperature in the modified method is 420‹F. for a time of 90 seconds. A suitable temperature and time to blow the layer containing the blowing agent are 420‹F. for 5-10 minutes, but the decomposition temperature of the blowing agent should match, as closely as possible, the fusion temperature of the resinous material. A suitable blowing agent comprises dinitrosopentamethylene tetramine and inert material which, with a wetting agent, is added to the mixture of plasticizer, stabilizer and pigment before the resin is added. When the mould has been cooled to a temperature below the softening point of the resinous material the moulded footwear article is stripped from it. The mould may have wings 20 to form an expansible pocket in the footwear to facilitate insertion of the foot. The mould may be made by a process in which a low temperature setting elastomeric moulding compound is moulded about a model of the flnished article, made of wood or plastic, and so forms a mould in which a former of plaster may be made. The plaster former is coated with nylon, by spraying, and molten aluminium composition is sprayed on the nylon covered former to the desired wall thickness to form the metal mould 10. The plaster former may then be destroyed and removed from the hollow metal mould. Specification 758,058 [Group VII] is referred to.

Title: Improvements in or relating to balances for fine weighing
Inventor: CHAPPELL FRANK ARTHUR
IPC: G01G23/08
Filed: 1962-09-13
Abstract: 970,788. Weighing apparatus. L. OERTLING Ltd. Sept. 6, 1963 [Sept. 13, 1962; Nov. 1, 1962], Nos. 34998/62.and 41433/62. Heading G1W. Relates to a weighing apparatus which has an arrangement for obtaining the approximate weight of an article before proceeding with the accurate weighing thereof. As shown. a weigh beam 13 pivoted on a knife edge 12 suspends from one arm a selected weight carrier 14 with weights 18 and from the carrier is suspended a weigh pan (not shown). The other arm supports a counterweight 19 attached to a piston 31 of a damping device. When rough weighing an adjustable spring 24 fixed to a bracket 25 pivotal on a stationary framework 10 acts on a knife edge 22 on the weighbeam to oppose the out of balance force due to an article on the weighpan. The beam is balanced when there is no load in the pan and all the selected weights 18 are in position. The damping device has an annular air outlet between the piston 31 and a cylinder 32. When rough weighing apertures 34, 35 therein are closed to give a high degree of damping and when fine weighing a cam 41 on a spindle 21 is operated to remove a spring flap from the aperture 35, also the position of a vane 36 relative to the aperture 34 is varied to adjust the damping rate. Operation. An article is placed on the pan and the beam deflection is noted on an indicator 42 (the strength of the spring 24 being such for example that one division of the scale indicator 42 represents 1g.). The beam is then arrested by a known arresting frame (not shown) and weights 18 are removed corresponding to the weight indicated on indicator 42. The beam is released and by means of a cam 26 on shaft 21 a lever 27 deflects the spring 24 out of the path of the knife edge 22 so that it no longer obstructs the beam movement and the cam 41 releases the blade spring 38 clear of the aperture 35. The balance now operates at high sensitivity, the weight of the load being shown on the scale indicator 42. Instead of a blade spring 24, a coiled spring or a counterweight may constitute the opposing force.

Title: Improvements in or relating to timing wave generators
IPC: H03L7/081
Filed: 1961-09-29
Abstract: 994,188. Pulse code modulation systems; transistor pulse circuits. WESTERN ELECTRIC CO. Inc. Sept. 29, 1961 [Nov. 2, 1960], No. 35081/61. Headings H3T and H4L. A pulse regenerator for intermittent pulse signals, e.g. pulse code modulation signals, is controlled by timing pulses which are derived from the incoming signals by a timing pulse generator, a portion of the output of the timing pulse generator being fed back to the input thereof during the absence of pulses from the incoming signal. As shown in Fig. 1 pulse intelligence signals are supplied via an amplifier 10 to a pulse regenerator 12 controlled by timing pulses on terminal 20 and the regenerated signal pulses are supplied via an amplifier 14 to the output terminal 24. A portion of the input signal is supplied via an OR circuit 36 in a logic circuit 26 to a band pass filter 28 tuned to the basic pulse repetition rate and the resulting timing pulses, after amplification and shaping at 30, are supplied to the terminal 20. In addition the timing pulses are supplied via feedback line 32 and delay 34 to an INHIBIT circuit 38 so that if in a particular time slot a signal pulse is present the fed back timing pulses are blocked from the OR circuit 36 but if no signal pulse is present the timing pulses are fed via the OR circuit 36 to the bandpass filter 28. In the arrangement shown in Fig. 2 a variable delay is introduced between the logic circuit 26 and the bandpass filter 28 and the output of the circuit 26 and the output of the amplifier 30 are supplied to a phase detector 42 to provide an error voltage controlling the delay 46. The delay 34, Fig. 1, is replaced by a variable delay 48 and the incoming signal pulses are compared in a phase detector 44 with the timing pulses fed back to the logic circuit 26 to control the delay 48 and ensure correct alignment of the two pulse trains. Devices 46 and 48 may consist of a length of transmission line terminated by its characteristic impedance in which a voltage operated motor varies the length of the transmission line. Alternatively an inductance-capacitance ladder network in which the capacitance varies with voltage may be used. Fig. 3 shows a logic circuit 26 for radio frequency repeaters. The R/F signal is supplied via a hybrid junction 52 to detector 54 which reproduces the negative half of the envelope 58, and 56 which reproduces the positive half 60. At the same time the negative timing pulse train 62 is supplied via feedback lead 50 to the base of a transistor 64. In the absence of signal pulses in the time slots of pulse trains 58, 60, the pulses 62 pass through the transistor 64 and transformer 68 to the output terminal 70. If pulses are present in the time slots, pulses 58 pass through the diode 66 and transformer 68 to the output terminal and pulses 60 applied to the emitter of the transistor 64 prevent the passage of pulses 62 to the transformer 68.

Title: Improvements relating to electric furnaces for glass melting
IPC: H05B3/03
Filed: 1952-12-17
Abstract: 756,382. Electrodes for electric glass furnaces. HANN, D. G. Dec. 17, 1953 [Dec. 17, 1952], No. 35117/53. Divided out of 31924/52. Class 39(3). In a glass melting furnace in which current is passed through the material in the furnace between electrodes immersed therein, the formation of seeds in the glass adjacent the electrodes is prevented by inserting a thermally resistive layer between the current supplying face of the electrode and a water-cooled stem or support of the electrode. Thus in an electrode comprising 5 molybdenum strips 10, 11 and a cross strip 12 bolted centrally at 27 to a watercooled carbon, steel or platinum stem 14, the central zone of the electrode plate carries a molybdenum plate 19 spaced outwards from the electrode but electrically connected thereto. The exposed face 20 of the plate 19 communicates current to the glass in substitution for the part 21 of the electrode which it overlies, and a thermally resistive barrier is established between the plate 19 and the central part of the electrode. The plate 19 covers one tenth to one fifth of the electrode and is rectangular with a longer dimension perpendicular to the central strip 10 and its shorter dimension equal to the width of the strip 10. The gap between the plate 19 and the electrode becomes filled with glass forming a thermal barrier, or may be filled with other material of low heat conductivity, e.g. a refractory cement, fused silica or asbestos. The thermal barrier is arranged so that the currentconveying surfaces of the electrode are at the same temperature and the current density in the glass adjacent such surfaces is uniform.

Filed: 1928-11-30
Abstract: 320,560. General Electric Co., Ltd., and Jackson, F. M. Nov. 30, 1928. Capillary - action lubricating; oil, catching. - In a bearing wherein lubricant is supplied to the journal from a reservoir by waste packing, lubricant escaping at the ends of the bearing is caused to flow to a second reservoir below the first reservoir and pneumatic means are provided for returning lubricant from the second to the first reservoir. As applied to an electric traction motor, the bush 5 is mounted in a bracket 1 adapted to be bolted to the end of the motor frame, the packing being contained in a chamber 6 one side of the bush and feeding lubricant to the shaft through openings in the bush. The chamber 6 communicates with a supply reservoir 9 on the other side of the bush through a passage 10. The outer end of the bracket 1 is closed by a disc 22 held in position by a ring 23 engaging an annular channel 24, and lubricant escaping from the outer end of the bush flows through passages 25, 26 to a lower collecting reservoir 27. Lubricant escaping from the inner end of the bush is throvrn by a grooved 'ring 17 on the shaft into annular recesses 15, whence it drains through a passage 28 into the reservoir 27. A pipe 31 leads from the reservoir 27 to an injector 32 provided with a nozzle 40 supplied with air under pressure through a pipe 47. Air discharged from the nozzle entrains lubricant flowing through the pipe 31 and carries it through a pipe 46 into a chamber 59 arranged above the reservoir 9. The air and oil are projected against the wall of the chamber 59, the oil thus separated flowing into the reservoir 9 through an orifice 61 in the dividing wall, while the air escapes through an opening 8. Alternatively, the lubricant may be returned from the reservoir 27 to a third reservoir adapted to maintain a constant level in the reservoir 9. The pipe 47 may be supplied from the motor cooling fan or by exhaust air from a brake cylinder.
