Title: Improvements in or relating to electric signalling systems
IPC: G01R17/08
Filed: 1930-08-12
Abstract: 360,499. Electric signalling systems LANDIS ET GYR, SOC. ANON., 1, Hof strasse, Zug, Switzerland. Aug. 12, 1930 No. 24118. Convention date, Sept. 2, 1929 [Class 40 (i).] In a signalling system for repeating at a distance measured quantities of the type wherein impulse indicative of a value of the quantity are trans mitted under the control a contact which is moved out of a neutral position by the quantity and is re stored by impulses, impulses of positive or negative polarity are transmitted over a single line circui to operate the receivers in one or other direction As shown in Fig. 1, the measured magnitude controls a contact 4 which co-operates with contacts 1, 2 to operate a motor 5 controlling interruption contacts 7. If in response to an alteration of the magnitude the contact 4 engages contact 2, the contacts 7 transmit impulses to operate the appropriate polarized stepping magnets 151, 15<11> of receivers D, E, and simultaneously operates one of the magnets 15 of a ratchet mechanism 20 which, through a spring 25, restores the contact 4 to its neutral position. Operation of the contact into engagement with contact 1, causes operation of a reversing switch 10 in addition to the operation of the motor 5. The switch 10 reverses the battery connections to the line wires, so that the impulses transmitted are of opposite polarity and affect the receivers D, E and the mechanism 20 in the reverse direction. A switch 13, which may be operated by hand or a time switch, is adapted when operated to initiate the transmission of impulses for zeroizing the receivers and contact restoring mechanism. The receivers may directly operate an indicating pointer e.g. 24<1> or control a potentiometer 27 in circuit with an indicating instrument 28. Instead of a potentiometer an induction regulator may be employed. The values of several quantities may be integrated at the receiving station, the impulses corresponding to the different quantities operating independent gears of a differential mechanism adapted to control a pointer.

Title: Improvements in brakes for railway carriages
IPC: B60T7/12
Filed: 1923-09-29
Abstract: 228,964. White, C. H., and Smiles, L. W. Sept. 29, 1923. Actuated by running axle; electric and magnetic.-In brake mechanism for railway vehicles of the kind comprising winding apparatus adapted to be driven by a running axle of the vehicle, the driving gear for the drum comprises a friction wheel adapted to be swung into engagement with the axle by a solenoid and a friction clutch adapted to be put into operation by a separately controlled solenoid for engaging the drum with the friction wheel. The winding drum 5 is freely mounted upon a shaft 3 mounted in a frame 7 which can be swung on pivots 8, 8<1> by the, plunger of a solenoid 10<1> so as to engage a friction wheel 2 with a sleeve on the axle 1. The wheel 2 forms one member of a cone clutch, the other member 6<1> of which is secured to the drum 5. Engagement of this clutch is effected by a boss 9<1> screwing upon a threaded part of the axle 3 and having an arm 9<11> connected to the plunder of a solenoid 10. The chain passes from the drum 5 around a switch drum 5<a> the free revolution of which is prevented by a braking device and which carries a ratchet wheel 5<b> arranged for engagement by a pawl 5<c> controlled by a rod 5d connected to an arm 7<1> of the swinging frame 7. To effect the application of the brakes the solenoid 10<1> is first energized to bring the friction wheel 2 into engagement with the axle 1, the subsequent energizing of the solenoid 10 causing the boss 9<1> to move the drum 5 laterally to engage the cone clutch members 6<1>, 2 and thus effect the rotation of the drum. The movement of the arm 7<1> on the frame 7 causes the pawl 5<c> to engage the ratchet wheel 5b to lock the brakes in the applied condition.

Abstract: 679,199. Sheet cutting, folding, and associating apparatus. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.-GES. Sept. 22, 1949 [May 25, 1949], No. 24331/49. Class 100 (i). Mechanism for collecting sheets cut from a web on a collecting cylinder 1 co-operating with a cutting cylinder 2 and a folding cylinder 4, comprises rows of impaling pins 5, 5<SP>1</SP>, and 5" for temporarily securing the sheets to the cylinder 1, the pins being arranged so as to be movable backwardly in the peripheral direction before the cutting of every first sheet 6 and forwardly in the peripheral direction after cutting each sheet 6 in order to produce a shorter sheet underlying a second longer sheet 7 both temporarily secured by the pins to the cylinder 1. The rows of pins 5, 5', and 5" are each mounted on a shaft 8 controlled by an eccentric disc 11 through a roller 10 and a lever 9 clamped to the shaft 8. The shaft 8 is mounted on a shaft 12 supported by eccentric pins 13, such that pivotal movement of the shaft 12 controlled by a lever 14 and a roller 15 engaging a cam 16 causes a rearward or forward movement of the pins in relation to the periphery of the cylinder 1. The cam 16 consists of two relatively rotatable parts, such that pivotal movement of the shaft 12 may be avoided by rotatable adjustment of the two parts; thus, sheets of equal length may be collected. When two sheets 6 and 7 have been collected on the cylinder 1 a folding knife 21 on the cylinder 1 pushes the sheets by their centre into a folding flap 20 on the cylinder 4.

Title: Party line ringing arrangements for automatic telephone exchange systems
IPC: H04Q5/06
Filed: 1944-12-08
Abstract: 594,137. Automatic exchange systems. STANDARD TELEPHONES & CABLES. Ltd. Dec. 8, 1944, No. 24601. Convention date, March 2. [Class 40 (iv)] In a multipotential marking system of the type described in Specification 592,846 the method which is used for double testing over two brushes as described in Specification 593,687 is modified to enable the character of the ringing current sent by the registercontroller over a party line to be determined by the test potential connected over the second brush. Each substation on the party line is designated by a different number and accessible over different terminals of the final selector. Each party line has two cut-off relays COR1, COR2 and two line relays LR1, LR2 over various contacts of which appropriate digit designating test potentials - N are connected to the T-terminals of the various substations and ringing-current determining potentials +b, +c, +d are connected to the B-terminals. When RSR and RSR2 operate under control of the registerswitch EO, AR and the power magnet P operate and the switch hunts for the characteristic -N potential on the T-terminal equal to that obtained over the brush RB in the register, and when such is found gas-valve GV1 strikes and GVR operates followed by GSR which releases GVR. Relay GRR energizes to operate RLR which connects characteristic potentials +b, +c, +d to the grids of valves V1, V3, V5. Meanwhile AR has released and if station 2, 3 or 4 has been selected potential +b, +c, or +d is connected from the B-brush to the grids of valves V2, V4 and V6. If station 1 has been selected no such potential is connected and when RSR2 releases the ringing circuit switches 33-cycle ringing current through ring trip relay DRR to the A and B brushes. Otherwise if, say, the B brush encounters +c potential gas valve GV2 fires and GVR2 operates to operate GSR2, thus causing 50-cycle ringing to be sent out. In the line circuit COR1 operating over the C- brush operates COR2 which switches over the B-terminals tu the b-wire of the party line. Relay COR1 operates LR2 and thus all the -N potentials are disconnected from the T- terminals of the substations concerned.
