Title: Improvements in or relating to traffic control systems
IPC: G08G1/082
Filed: 1936-03-30
Abstract: 472,832. Road signals for controlling traffic. AUTOMATIC ELECTRIC CO., Ltd., RENSHAW, A. P. B., and THOMPSON, G. W. March 30, 1936, No. 9394. [Class 118 (ii)] In a system in which signals at a number of adjacent intersections are fully vehiclecontrolled, a vehicle passing one intersection controls the transmission of a signal to an adjacent intersection which ensures that, if right of way is with the main road, the normal maximum timer recommences to measure the maximum period after a given time period, this time period being adjusted to allow green wave signalling along the main road. The invention is described as applied to three intersections X, Y and Z, Fig. 3, the equipment at intersection Y being indicated in Figs. 1 and 2, and the interconnecting equipment being shown in Fig 4. The apparatus at each intersection comprises the normal timer FA, A, QA controlled over resistance AR to time the initial and vehicle intervals and the amber period, a maximum timer B, FB, QB and an additional timer C, FC, QC. In ordinary practice the apparatus at Y is controlled by pads DB, Fig. 2, in the side streets and by pads band e, Fig. 3, which energize relays O and P, Fig. 4, to control relay E, Fig. 2, If an approaching vehicle crosses pad a and the right of way is with the cross-street, relay 10, Fig. 4, is energized and locks relay 1RA (not shown), being operated in parallel with the red lamp similarly to relay RA, Fig. 1, at Y. When the signals change to amber, relay 1AA (not shown), pulls up and contacts Q, R are bridged to energize relay E, Fig. 2, and relay OR, Fig. 4. If the right of way at Y is with the crossstreet, relay E initiates transfer to the mainroad in the normal way. Relay OR connects up the timer C, FC, QC, which is adjusted to take the same time as a vehicle travelling at a normal speed takes to travel from pad a to pad b. At the end of this period relay C operates and relay MR pulls up to release OR. If, at Y, right of way is with the main road, so that relays AA and RA are both back, relay M also energizes and locks so that the maximum timer is connected over switch MA. At the same time relay C discharges condenser QB so that the maximum timer recommences to measure the maximum period. The release of relay OR releases relay C and discharges condenser QC. If contacts 10 and 11, Fig. 2, are joined as indicated, the relay M is energized when C pulls up irrespective of whether right of way is with the main or cross-streets, and this may help to bring the units at the crossings into synchronism more quickly. If vehicles are approaching over pad d, the operation is similar, the control being through relay PR and switch PD2. The pads at intersection Y exert similar control on the apparatus at intersections X and Z. Specifications 403,732 and 446,288 are referred to.

Title: Improvements in electrically and thermostatically controlled apparatus
IPC: G05D23/30
Filed: 1923-04-05
Abstract: 195,974. Aktiebolaget Birka Regulator. April 6, 1922, [Convention date]. Thermal switches, cut-outs, and interrupters.-The operating circuit of an electrically heated thermostat 3 for controlling switches, for regulating current supply to an electric heater or for controlling the admission valves of radiators, is controlled by an auxiliary thermostatic switch 7, brought into operation by the closure of the said operating circuit and operating to reduce the supply of energy to the thermostat 3. after a period of time substantially the same as that required for causing the thermostat 3 to function. The thermostat 3 is normally closed to complete the circuit from the main leads 2 through a switch 15 to an electrical radiator 1. A thermostatic relay 5, having an adjustable contact 11, normally opens the operating circuit of the thermostat 3. When the temperature of the room heated by the radiator reaches a certain value, the relay 5 closes the operating circuit, so that the thermostat 3 becomes rapidly heated and opens the radiator circuit. The auxiliary thermostat then causes intermittent breaking and making of the operating circuit, the arrangement being such that the thermostat 3 receives just enough energy to keep the radiator circuit open while the relay 5 is closed. If desired, the thermostat 7 may insert a resistance in the operating circuit without breaking the latter, and the heating coil 6 may be in a separate circuit closed by the thermostat 3 when in operation. A lamp 14 is arranged in the operating circuit. The thermostats are shown as bimetallic strips, but any expansible solid or fluid may be used. The thermostats 3, 7 are arranged in evacuated or gas-filled receptacles 12, 13, and the contacts are preferably of tungsten, molybdenum or tantalum. The Specification as open to inspection under Sect. 91 (3) (a), states that the apparatus may be used for controlling rheostats, and that the relays 5 may be replaced by a purely mechanical device. This subject-matter does not appear in the Specification as accepted.

Abstract: 443,093. Hydraulic brakes. EVANS, W. E., 27, Chancery Lane, London.-(Veremigte Stahlwerke Akt. - Ges. ; 67, Breitestrasse, D³sseldorf, Germany) May 14,1934, No. 9487. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 21, 1935.] [Class 103 (i)] Brakes mounted on the railway track, hydraulically controlled and in which the weight of the vehicle produces the braking force are provided with a pressure regulator having a control lever o, a supply valve i adapted to close the supply pipe h, an exhaust valve k adapted to connect the cylinder d to the exhaust pipe m and a pressure-limiting valve n which can be variably loaded by the lever o through the spring p to allow discharge of liquid from the cylinder d. The supply of pressure medium is taken from an accumulator or a water main. The cylinder d operates the track brake to raise it to operative position, through a spring g, and plunger f connected by a pipe b to the brake cylinder a. The weight of the brake is balanced by a weight f<1>, connected to the plunger f. In a modified form of regulator fluid is normally circulated by a pump through passages 1, 19, 3, Fig. 2. To apply the brake a valve 2 is closed by the lever 4 and pressure develops in the pipe 11 leading to the brakes and the cylinder 18, the piston 13 of which re-opens the valve 2 when the brake pressure attains the desired value. A check valve 10 maintains the pressure in the brake. The same self-lapping action takes place when the brake is exhausted by the valve 17.

Abstract: 564,237. Projection screens. KODAK, Ltd. June 16, 1943, No. 9675. Convention date, June 30, 1942. [Class 97 (i)] A rear projection screen comprises a light-absorbing layer into which external light - refracting bodies each forming alight aperture therethrough. The bodies may be spherules 17 of glass, natural or synthetic resin, &c., and may be coloured or colourless. The lightabsorbing layer 16 may be dyed thermoplastic material, gelatin, lacquer, Brunswick black, asphalt varnish, exposed, developed and fixed photographic emulsion, &c., and may support the spherules 17. The layer 16 may be supported on a glass or other transparent sheet 15, or may be stripped therefrom, and the spherules may contact with the sheet 15, or may be separated therefrom by a thin portion of the layer 16. The screen may be made by feeding the sheet 15 by an endless belt under a hopper delivering the light-absorbing medium thereto, into a drying chamber, under a box delivering the spherules on to the layer 16, and into a heating chamber ; the spherules then settle into the layer 16 and may be rolled into it. Distribution to form a single layer may be effected by a doctor, or air jets, or by agitation of the sheet 15. The layer 16 hardens when the screen has passed from the heating chamber and may be stripped from the sheet 15.
