Abstract: 1,100,880. Monitoring P.C.M. systems. GENERAL ELECTRIC CO. Ltd., 11 July, 1966 [9 July, 1965], No. 29202/65. Heading H4L. In a monitoring arrangement for a P.C.M. communication system, a plurality of successive digits are stored periodically in stores 1 (at the coder or decoder) whose outputs are supplied to integrators 2. With the natural binary code, in which one half of the code representations of a range of magnitudes constitute a reflected image of the other half, the average level of the audio signal being aligned with the centre of the code range, each digit will have each of its two values for approximately half the total time when this total time is large compared to the period of the lowest frequency component of the audio signal. Consequently the positive and negative outputs from each of the integrating circuits 2 will be equal with normal operation. These positive and negative signals are supplied to gates 3 and 4 respectively and should a discrepancy occur one or other of the voltage-responsive devices 5, 6 will operate an alarm 7. The arrangement may be modified for other binary or other than binary codes.

Title: Improvements in and connected with installations for electrically lighting, heating and ventilating railway and like vehicles
IPC: H02J7/14
Filed: 1925-11-23
Abstract: 266,434. Stone & Co., Ltd., J., and Darker, A. H. Nov. 23, 1925. Supplying consuming devices from variable speed generators. -In lighting heating and ventilating systems for railway and like vehicles comprising a number of parallel - connected dynamobattery units, control means prevent overcharging of the batteries by stopping, reducing or diverting, e.g. into heat-storing means, the current from one or more of the generators, according to load conditions. A lamp circuit switch may insert resistance into a dynamo-field circuit or open a dynamo circuit directly or indirectly, as through the agency of a voltage relay or relays across the dynamo and battery circuit. The operation of the latter may be controlled by hand to permit a full charge to be given when desired, and such control may operate through a demagnetizing coil on the relay; an automatic switch operated when the battery volts are low may be employed for this. A separate switch or an arrangement of the flexible couplings may be used to restore normal conditions in a detached vehicle. Two generating equipments supply the five coach train shown in Fig. 1 the dynamo d<2> being adjusted to give lamp voltage only. A changer-over switch e, e<1> places one battery on charge from the dynamo d<1> at a time, the other 'floating.' The dynamo d<2> cannot cut in unless the right-hand switch o controlling half the train lights is closed since otherwise a resistance t is inserted in its field circuit. The dynamo d<2> may be designed to assist the charging when the lighting switch is closed. Fig. 2 shows a modified single-coach equipment for parallel connection in a train. The field resistance t is controlled by a potential coil v connected across the dynamo d by an auxiliary blade q on the lighting switch and across dynamo and battery when the cut-in switch h closes. The resistance t is then cut-in if the battery is fully charged when the dynamo cuts in and the dynamo then cuts out or its output is considerably reduced. When the lights are switched on the coil v is cut out and the risistance t short-circuited. The coil v may be made inoperative by a hand switch z, or by demagnetizing windings controlled by a hand switch or an automatic switch opened on low battery volts. All the coils v in a block train may be controlled by a single switch. Leads 1. 2 may be taken from the terminals of resistance t to a switch on the end of a coach so that a detached coach equipment may be made to function independently; the connection of these leads together may be automatically effected by the .uncoupling. The foregoing arrangements are designed for slipping-belt dynamos but dynamos requiring electrical regulators may have the regulator action modified by lamp circuit or battery conditions. The control means may be arranged to divert the output into resistances in shunt with the batteries.

Filed: 1939-11-07
Abstract: 536,262. Conveyers. DUMBLETON, C., and BAKER PERKINS, Ltd., Nov. 7, 1938, No. 29578. [Class 78 (i)] Articles such as biscuits are traversed alternately in opposite directions on conveyers and turned over during the process. Thus, articles carried on the conveyer 5 are delivered to the conveyer 7 moving in the opposite direction by the driven endless belt 8 of, or faced with, felt, flannel or sponge rubber, which laps the end pulley 6 of the conveyer 5 and delivers over the knife edge 11. The conveyer 7 may deliver by similar means to a third conveyer running in the same direction as the conveyer 5 and so on. A screw-adjusted tension spring 14 acts in the axis of the pulley 9 and allows the belt 8 to yield under pre-determined pressure to avoid damage to the goods. As shown, the belt 8 is driven by gear wheels from the pulley 6, but it may be driven by direct contact with a friction roller, co-operating with one of the guide rollers.

Abstract: 657,595. Charging two-stroke engines. SCHNUERLE, A. Nov. 15, 1948, No. 29591. [Classes 7(ii) and 9(iii)] In a four-cylinder two-stroke V-type engine, in which the cylinder banks 1, 2, are at an angle of 90 degress and the cylinder exhaust and scavenging ports 22, 21 are piston-controlled, the scavenging air is supplied by a blower 6 driven by constant transmission ratio gearing from the crankshaft. The crank-shaft comprises two crankpins at 180 degrees to each of which is connected side-by-side the connecting rods from a cylinder in each bank 1, 2, whereby the cylinder bank 1 is displaced rearwardly with respect to the bank 2. This displacement allows the volute of the blower 6 to increase in width in an axial direction towards its outlet 16, adjacent the bank 1, which leads into a scavenging air receiver 5 formed in the crankcase between the cylinder banks and connected by passages 20 to the scavenging ports 21. The blower induction pipe 17 has a filter 18. 'The blower casing 16 may be formed integral with the casing or as a separate member, and a fuel injection pump driven from the crank-shaft may be situated on top' of the receiver 5. In a modification the blower volute is of usual centrifugal form i.e. of constant axial width and a cross-section increasing radially through out its length.

Abstract: 249,187. Richardsons, Westgarth, & Co., Ltd., and Burn, W. S. Dec. 12, 1924. Cam-and-lever actuated pumps; stroke-varying. -The fuel pumps and the master valves for controlling the supply of starting-air to internal-combustion engines are arranged to be controlled by a single hand wheel in such a way that the starting-air valves are first brought into operation, and are afterwards put out of action as the fuel pumps begin to operate, the action of the latter being then varied by adjustments of their stroke and the opening of their suction valves by means of the same hand control. The fuel pumps 2 have their plungers 1 actuated by cams 3 and levers 4, and their suction valves 6 worked by bell cranks 7 connected by links 8 to the levers 4, the delivery valves 12 being automatically opened by the fuel pressure. The levers 4 and 7 are mounted on eccentrics 9 and 10 respectively, which are simultaneously adjusted by means of a hand wheel rotating through worm gear the shaft 19 of the eccentrics 9, cams 20 on these shafts also adjusting the eccentrics 10 through linkage connections 21, 22, 23. The eccentric 10 may be adjusted independently by a governor through a slotted connection 25, and a further adjustment of the suction valves is obtained by means of a screw 11. The master valves for the starting-air are actuated by further cams provided on one end of the shaft 26 carrying the cams 3, the levers working these valves being also mounted on eccentrics on the shaft 19. In double-acting engines, the hand control first brings into action starting-air valves at the upper ends and the fuel pumps at the lower ends of the cylinders, and afterwards cuts out of the starting-valves and brings the fuel pumps for the upper ends also into action. Reversing is obtained by axial adjustment of the cam shaft so as to bring a duplicate set of cams into action.
