Title: Railway vacuum braking systems
Inventor: MARSH GERALD CRANTON
IPC: B60T13/46
Filed: 1965-08-23
Abstract: 1,113,502. Railway vehicle braking system. GRESHAM & CRAVEN Ltd. 5 Aug., 1966 [23 Aug., 1965], No. 36004/65. Heading F2F. A railway vehicle vacuum braking system comprises at least one brake cylinder having two chambers 4, 5, a train pipe 10 connected to one 5 of the chambers and a further train pipe 11, for separately charging the other chamber 4 during a brake application. A piston 3 separating the chambers 4, 5 is provided with a one-way valve 6 such that gas can pass from chamber 4 to chamber 5 and, on movement of the piston 3 in the brake applying direction, a rolling ring 36 moves past a port 7 in the piston to cut off all possible connection between the two chambers 4, 5. An automatic isolating valve 14 is interposed between the train pipe 11 and the chamber 4, vacuum above a diaphragm 26 of the valve allowing atmospheric pressure on a flange 27 of a stem 25 to overcome the bias of a spring 30 such that the stem 25 moves to unseat a valve member 23. The ultimate pressure in both train pipes is limited, the ultimate pressure in train pipe 10 being lower than that in train pipe 11 such that the train pipe 11 can be evacuated through the valves 14 and 6 although an exhauster is connected to this train pipe 11. A reservoir 18 is also evacuated. Thus a brake application can be effected even if the train pipe 11 is defective, the valve 14 closing automatically. When the brakes are applied communication between chambers 4, 5 is cut off with the result that on release of the brakes the pressure in chamber 5 becomes lower than that in chamber 4, the piston 3 then moving to the brake release position. A manually actuated valve 35 is provided between the two chambers.

Title: Surface sealing structures
IPC: E04D5/10
Filed: 1975-09-02
Abstract: 1519045 Sealing structures DYNAMIT NOBEL AG 2 Sept 1975 [3 Sept 1974] 36176/75 Heading B2E [Also in Divisions B5 and El] A sealing structure for application to an exposed surface of a building or civil engineering construction comprises a synthetic thermoplastic or plastic sheet having embedded therein a fabric reinforcement and a plurality of zones which impart to the sheet a greater reinforcing effect than the remainder of the fabric extending in strips lying across the fabric in one direction or in two directions disposed at right angles to one another, the thermoplastic material on the two sides of the fabric being the same, but differing insofar as they contain different contents of stabiliser and/or filler. The fabric reinforcement may be completely embedded in the sealing sheet and the sealing sheet may be of soft polyvinyl chloride. The reinforcing zones may be obtained by a greater concentration of filaments of the fabric and/or by thicker filaments than those found elsewhere in the fabric reinforcement. The thicker filaments may be formed from a material different from that from which the remainder of the fabric reinforcement is made. Alternatively, the reinforcing zones may be constituted by pre-formed strips of a further material such as polyester, polyamide, polyethylene, polypropylene or polycarbonate or of metal. The metal may be ferromagnetic. The material may be made by applying a first plastisol of a synthetic plastics material e.g. polyvinyl chloride, polyisobutylene, and butyl rubber to a continuous support at ambient temperature, laying on the plastisol while it remains in an ungelled state the reinforcing fabric, heating the assembly to 160-200‹C to partially gel the plastisol and bond the plastisol with the fabric, applying a second plastisol of a synthetic plastics material which is the same as the first, but differing in the content of stabilizer and/or filler, heating the assembly to 160- 250‹C to effect substantially complete gelling of the two layers and removing the composite assembly thus formed from the continuous support.

Title: Improvements in or relating to temperature control circuits for electric furnaces
IPC: G05D23/22
Filed: 1960-10-28
Abstract: 963,703. Automatic temperature control. STANDARD TELEPHONES & CABLES Ltd. Oct. 28, 1960, No. 37140/60. Heading G3R. A furnace 6 having a heating element R4 embedded in an electrical insulating material is supplied through a variable ratio transformer T1 from a mains A.C. supply. The temperature of the furnace is sensed by a device Y connected to a temperature controller 6<SP>1</SP> which actuates contacts TC1, TC2 in dependence on the temperature deviation to drive the motor M and position a slider 8 of the transformer T1 so as to correct the temperature deviation. A current transformer T2 through a rectifier W1 energizes a contact-making meter C/1 having a moving contact arm C1 which normally engages a fixed contact a to actuate a relay D/2 closing contacts D1, D2 in series with contact TC1. When the heating element current is at a preset value the contact arm is free and above the preset value the contact arm engages a contact b to actuate a relay F/1 to close a contact F1 and energize the motor M to move the slider 8 in a direction which will reduce the heating element current below the preset value. Simultaneously, the relay D/2 is deenergized to open the contacts D1, D2 and isolate the temperature controller contact TC1. The preset current is adjusted by resistors R1, R2. The system is started up by closing contacts S2 to operate a contact or A/3 having a hold-on contact A3 in parallel with contacts S2 and contacts Al, A2 in the supply to the transformer T1. A lower limit switch BLS of the transformer T1 is also in series with the contactor and prevents start-up except with minimum heating element-current. Contacts E1 of a relay E/1 across the supply short-circuit contacts BLS when contactor A/3 is closed. The system is manually shut down by opening contacts S1 and a overload relay B/1 automatically shuts down the system by opening contacts B1. The resistance element of the furnace may be tungsten, molybdenum or silicon carbon and hydrogen is passed through the furnace.

Abstract: 914,223. Gyratory crushers. NYBERG, J. E. Oct. 17, 1961 [Oct. 19, 1960], No. 37260/61. Class 59. A gyratory crusher shaft 30 which supports a crushing head 72 through the medium of yielding members 88, 94, Fig. 1, is driven by a crank or eccentric mechanism 42. The crankpin 42 is arranged to rotate in a roller bearing casing 36 attached to the shaft 30 which is supported in a spherical bearing 66 at its lower end. The crusher head 72, which has a wear jacket 74, is mounted between a spherical portion 78 on the shaft 30 and a sleeve 88 slidable on the shaft. The sleeve 88 has a conical upper surface 84 engaging a corresponding surface 82 on the lower end of the head 72 and is axially and resiliently supported by piles of resilient washers 94 on a collar 96 fixed on the shaft. In operation, the crank 42, which is provided with a balance weight 56, is rotated by a motor 58 to roll the head 72 around the crushing chamber and, upon an uncrushable object entering the chamber and dropping to a point A, the head, guided by the spherical portion 78 of the shaft moves against the sleeve 88 so as to force the latter down on its resilient mounting. In the modification shown in Fig. 2, the sleeve 88 has an extension in the form of a tubular piston 104 hydraulically supported in a cylinder 106, and, in the event of the sleeve being displaced, the liquid in the cylinder is forced through a bore 110 in the shaft and conduits 114, 128 against a pressure which restores the sleeve when the uncrushable object leaves. Movement of the sleeve and the resultant increase in hydraulic pressure may be used to operate a warning signal device, stop the crusher motor 58 or lift the head and shaft clear of the chamber casing. The piston extension 104 of Fig. 2 may be replaced by a cylinder arranged to co-operate with a piston secured to the shaft 30 and a jaw clutch may also be provided to prevent unnecessary wear of the faces 82, 84 of the head 72 and sleeve 88.

Title: Automatic Fire Alarm System
IPC: G08B17/06
Filed: 1966-08-19
Abstract: 1,160,760. Fire alarms. HOLGER NIELSEN & CO. A/S. 19 Aug., 1966 [21 Aug., 1965], No. 37366/66. Heading G4N. A fire alarm system comprises a plurality of temperature-responsive relaxation oscillators coupled to a central station and a further relaxation oscillator arranged to feed pulses of different amplitude to the central station for line testing purposes. All the temperaturesensitive oscillators and the line-testing oscillator are coupled in parallel to the central station by means of one signal conductor 6 and a pair of power supply conductors 4, 5. Each temperature-responsive oscillator may comprise a capacitor C1 (Fig. 4) chargeable at a rate depending on the relative values of an adjustable resistor R1 and a temperature- or radiation-responsive resistor T, unijunction transistor T1 breaking down when C1 is charged sufficiently, the frequency of pulses thus generated being a function of temperature around resistor T. The pulses produced by T1 are amplified by T2 and fed to the central station on a common signal lead 6. The breakdown voltage of transistor T1 is made independent of the voltage on supply lines 4, 5 by means of a Zener diode Ze1 Fig. 3 (not shown) depicts a line-testing oscillator generally similar to that shown in Fig. 4 but omitting the temperature dependent resistor T and including a Zener diode in the collector circuit of T2 so as to provide pulses of different amplitude from those of the temperature sensors. Central station (Fig. 6).-Alarm signal pulses on line 6 are arranged to swing from + 12 V. to 0 so that they can pass diode D2 to an integrator comprising capacitors C1, C2 and transistor T1 If the frequency is sufficiently high (indicative of a high-temperature condition), unijunction transistor T2 will break down, triggering SCR, energizing a lamp AL and a relay RE2. Line testing pulses are arranged to swing from + 12 V. to + 9 V. and thus cannot pass diode D2 but are fed only into the integrator C3, C4, T3 which is coupled via a super emitter follower T4, T5 to a relay RE1. Under normal operation this relay is energized, so as to light a lamp KL, but under fault conditions the relay becomes released, energizing a fault lamp FL. The supply to the local sensors on line 4 is also disconnected under these conditions. The alarm circuit may be reset by operating push button TR. The sensitivity of all sensors is adjustable by potentiometer 21.
