Title: Improvements in closed circuit turbine power plants
Inventor: VELLAN ALEXANDER
IPC: F24V50/00
Filed: 1954-08-03
Abstract: 785,035. Elastic-fluid turbines; vapour engine power plant. PRIME MOVERS, Ltd., C. V. Jan. 6, 1955 [Aug. 3, 1954], No. 22463/54. Classes 110 (3) and 122 (3). A heat source at a temperature level below 200 C. is utilized to heat a working fluid which is gaseous at normal temperatures and pressures and constitutes the working medium in a closed cycle turbine plant. The heat source is waste steam or gases or a natural source such as springs, mine water or solar heat. The working medium may be carbon or sulphur dioxide, or ammonia. The heat is supplied to the medium in a counterflow heat exchanger 5 and the turbine 2 exhausts through a second counterflow heat exchanger 12 and a condenser 13 to a vessel 14. A pump 15 recirculates the medium after raising its pressure substantially above the critical pressure.
Patent GB-250462-A (GB)
Title: Apparatus for receiving and conveying articles from a glassware-forming machine
IPC: C03B35/06
Filed: 1925-09-08
Abstract: 250,462. Pollak, J. E., (Owens Bottle Co.). Sept. 8, 1925. Blowing; taking-in devices. - Relates to a device for receiving bottles or other glass articles as they are delivered from a forming-machine and for transferring them to a conveyer or other support. The device is designed particularly for use with a machine in which a number of bottles are delivered at approximately the same time, and it comprises a number of guides each of which receives a bottle and keeps it out of contact with other bottles. The forming-machine has two finishing-moulds 11, Fig. 2, mounted on each of its arms 12, and each finishing mould is formed with three mould cavities so that six bottles are formed simultaneously by each set of moulds. As the moulds are opened near the discharging position, the bottles are supported by a pair of knock-out arms 14 each of which carries discs a - - e, Fig. 7, that press on the mouths of the bottles. When these are are lifted and swung apart by a cam 85, Fig. 2, the bottles are released and fall into funnels 33 forming part of the delivery device. The knock-out discs a - - e, Fig. 7, are adjusted so that they assume different levels when lifted off the bottles. With this arrangement the bottles are not released simultaneously but at different periods in quick succession. The funnels 33 each comprise a stationary section and a swinging section 31 which is supported and rocked by a shaft 37 in time with the movement of the forming-machine. The bottles are received from the machine and held, and then are released simultaneously by the movement of the sections 31. The bottles thus released fall into a shoot 25 which comprises a number of troughs or guideways separated from one another by walls. The bottles slide down these troughs on to a conveyer belt 63 by which they may be carried into the leer, and the walls prevent them from touching one another and sticking together. The shoot 25 is so supported that it may be moved up and down, and towards or away from the machine.

The means comprise a ram 20 for extending the arm and a ram 40 for pivoting the arm. Associated with the rams are valve assemblies that are arranged to detect when the telescopic arm is fully extended from the non-operative position into the intermediate position, to initiate action of the ram to pivot the arm towards the operative position when the arm is fully extended and vise versa when the arm is to be moved away from the operative position. A linear potentiometer is provided to sense the extension of the ram 40. The arm 11 is divided by internally located framework into compartments, in one of which is located the ram 20 and in another of which are located flexible members connecting the probe with control means on the body of the machine.

Abstract: 776,110. Musical boxes. MATTEL, Inc. Aug. 5, 1955 [April 4, 1955], No. 22664/55. Class 88 (1). [Also in Group XV] A toy vehicle is provided with a musical comb, the teeth of which are arranged for plucking by a member driven through a clutch by the turning of the wheels of the vehicle. As shown, an endless belt 53 has protuberances 54 for engagement with teeth 43 of a musical comb 41, the belt being supported at one end by a shaft 44 on which a friction wheel 51 is secured. The rear axle 14 of the vehicle is mounted in vertical slots 20 and a pivoted clip 33 is rotatable to lock the axle in its lower position or to urge the axle upwardly against the tension of a leafspring 23.

Title: Improvements in or relating to train vigilance control systems
Inventor: BOWRAN JACK
IPC: B60L3/02
Filed: 1967-05-16
Abstract: 1,244,601. Train vigilance control system. DAVIES & METCALFE Ltd. 7 Aug., 1968 [16 May, 1967], No. 22669/67. Headings B7H and B7N. In a train vigilance control system two modes of operation are provided, first a vigilance mode in which a vigilance period is followed by a warning period before application of the train brakes and second a safety mode in which on release of a dead man's pedal, the train runs for a very short period followed by a short warning period before application of the train brakes. On operation of the dead man's (DM) pedal relay RL2 picks up and on movement of its contact 3 from position 4 to 5 bias is momentarily applied to thyristors THY2 and THY4 to trigger these into conduction. Additionally, change-over of contact 9 from position 11 to 10 commences charge of capacitor C1 via R5 which determines the vigilance time cycle. During this cycle any operation of the train driving controls unbalances a thermistor bridge TH1- TH4 whereby a relay RL3 momentarily picks up to open the circuit to relay RL2 opening momentarily the circuit to Cl which discharges and then recommences charging from zero. If no driving control action occurs Cl charges up to a value which biases uni-junction transistor UJT1 into conduction and the resultant discharge of Cl triggers transistor THYl on and via capacitor C2 stops conduction of thyristor THY2. Relay RL1 now picks up to operate the bell 12 and also to apply a charge to capacitor C3 via resistor R8. In addition, the circuit of RL2 is now held via contacts 1, 3 of relay RL1 so that the apparatus can only now be returned to its initial state by momentary opening and closing of the DM pedal. If this action is not taken capacitor C3 charges to a valve which biases UJT2 on and the subsequent discharge of the capacitor triggers THY3 on and via capacitor C4 thyristor THY4 is cut off and the electro pneumatic valve 4 is released to operate the train brake. The vigilance and warning cycles are 1 minute and 30 seconds repeatively. The safety mode comes into operation when the DM pedal is released and this mode is similar in operation except that the capacitors C1 and C3 are now charged via resistors R4 and R7 giving a first period of two seconds and a second warning period of five seconds before the brakes are applied.
