Title: Theft-alarm equipment
Inventor: RICE GRAHAM
IPC: G08B25/00
Filed: 1966-11-02
Abstract: 1,212,972. Burglar alarms. G. RICE. 31 Jan., 1968 [2 Nov., 1966], No. 49130/66. Heading G4N. In an alarm system, a pair of record reproduction devices are arranged to reproduce identical recordings in synchronism, one of the reproducers being arranged to be reponsive to an unwanted condition, a comparator 18 being arranged to operate an alarm 21 if the outputs of the two reproducers is appreciably different. In the system shown, for protection of a safe at a bank, a double tape recorder 11 records random binary signals on duplicate tapes, one of which is attached to a reproducer contained in the safe whilst the other is taken in a sealed container to the police station where it is attached to a further reproducer 17. When the bank is to be vacated, an initiation signal, e.g. from a time switch, is arranged to start both reproducers in synchronism. The reproducer in the safe is arranged to be interrupted by an attempt to open the safe or by cutting line 19 whereupon comparator 18 operates an alarm 21. A delay device may be included so that the comparator only operates on selected parts of the signals from the two reproducers. The tapes may be recorded at high speed from a feedback shift register with a noise-operated gate and may be reproduced slowly over three days. Alternatively, the tapes could be replayed in steps over a period of some years. The interruption of the reproducer in the safe can be arranged also to stop reproducer 17 so that both devices may be re-operated in synchronism when the system is restored.

Title: Transportation system
IPC: B60L13/00
Filed: 1973-10-31
Abstract: 1448253 Transportation systems W W CUSHMAN 31 Oct 1973 [8 Nov 1972] 50713/73 Heading B7L A transportation system comprises a constant speed closed loop transporter means 12 formed by an interconnected series of carriers 36, and a variable speed closed loop transfer means 14 formed by an interconnected series of carriers 38, the whole of transfer means 14 being slowed down to rest for receiving passengers at stations 16, 18, 20, 22 and accelerated until its speed is substantially equal to that of the transporter means 12 for transfer of passengers between means 14 and 12 which are contiguous and coextensive with one another. In the main embodiment shown in Fig. 6 each carrier 36 has a laterally extending platform portion 134 which supports a carrier 38 for movement relative thereto on a series of roller means 156 which are interconnected by two series of endless belts 192 and 194. Similarly, the carriers 36 are suspended on wheel assemblies 84 which are interconnected by series of belts 114, 116 engaging in grooves in the axles of the assemblies 84. The interconnected roller means 156 thus form a closed loop extending around the transfer means 14, and the interconnected wheel assemblies 84 also form a closed loop. Assemblies 84 are preferably not positively connected to the carriers 36, but run freely on rails 76, 78 carried by the undersides of the carriers and on rails 72, 74 carried by a support structure 68. The carriers 36 are propelled at constant speed by a linear induction motor 264 of which stator means 268 are carried by the support structure 68 and armature means 274 are carried by the carriers 36. For transfer of passengers between carriers 36 and 38, no propulsion of the carriers 38 is needed since they are carried on the extended portions 134 of the carriers 36, but for transfer from carriers 38 to stationary platform 44 the carriers 38 must be decelerated to rest relative to the platform 44. To achieve this, the carriers 38 are drivable relative to the carriers 36 by a linear induction motor 266 of which stator means 278 on carriers 36 react with armature means 280 on carriers 38. During passenger transfer between carriers 36 and 38, gate or barrier means 126 are lowered flush with the floor of the carriers 36 and similar gate or barrier means 52 are raised as shown. During acceleration or deceleration, all of means 52 and 126 are raised, and means 52 are lowered when the carriers 38 are at rest at a station.

Title: Method employing valve management for operating a steam turbine
IPC: F01D17/22
Filed: 1973-11-05
Abstract: 1429324 Automatic control of turbines WESTINGHOUSE ELECTRIC CORP 5 Nov 1973 [15 Nov 1972] 51201/73 Heading G3N [Also in Division F1] A steam turbine having a series of steam inlet valves is controlled by sequencing the valves over a limited control range to satisfy a turbine load demand in accordance with a stored characterization which is modified to accommodate for increased flow resistance with increasing steam flow through the turbine. As shown, a turbine 10 drives an electric generator the power output of which is measured by a detector 18 and speed by detectors 58, 59. The turbine 10 includes a high-pressure turbine section 20, an intermediate section 22 and a low-pressure section 24. Steam is provided by a steam generator 26 and directed to a steam chest by throttle valves TV1-TV4 operated by actuators 42. From the steam chest flow to section 20 is controlled through inlet valves GV1-GV8, operated by actuators 44; each valve may comprise a plurality of valves in parallel. From the section 20, the steam flows through a re-heater 20 to the sections 22, 24 and exhausted to a condenser 32. Stop valves SV and interceptor valves IV, operated by actuators 46, 48 respectively, modulate steam flow under overspeed conditions. The actuators 46, 48, 42, 44 are hydraulic and fed from a supply 49. The actuators 42, 44 are positioned by controls 50, 52 respectively, actuators 48 by a position control 56 and actuators 46 are fully open except when tripped. Feedback to the controls is provided by position detectors PDT1-PDT4, PDG1- PDG8 and PD1. The set-points SP of the valves are determined by a computer and periodically updated. The turbine is controlled by a programmed computer in dependence on the number of governor valves already open, and the position of a valve takes into account a correction factor which is the ratio of the actual flow at the flow demand to the theoretical flow if the orifice flow was equal to one and the back pressure was zero. Data representative of this relationship is stored in the computer memory. In sequential valve operation the maximum flow through each governor valve in succession is subtracted from the flow demand thereby determining the number of valves to be fully opened and the remaining flow through the partially open valves. A flow chart for the steam inlet or governor valve control program is described.

Abstract: 1,070,320. Packaging-machines. AKERLUND & RAUSING A.B. Dec. 8, 1965 [Jan. 2, 1965], No. 52091/65. Heading B8C. Coffee beans are ground and packaged in an inert atmosphere such as carbon dioxide or nitrogen, the ground coffee being passed into a tube of the packaging material, which is then successively sealed to form individual unit packages. As described (Fig. 1, not shown), a web 6 of the packaging material is formed into a tube (7) around a filling pipe 4. Air is first removed from the apparatus by passing the inert gas, via a valve 9, through a conduit 11, which is introduced into the open end of the tube (7) to cause the gas to pass through the tube (7), filling pipe 4, dispensing means 3, grinding mill 2 and finally to atmosphere through a hopper 1. Sampling conduits 18 provide means for measuring the residual oxygen content. After air removal, the end of the tube (7) is closed by sealing means 12 (Fig. 2) and the valve 9 reversed to cause the gas to flow through a conduit 10 directly to the filling pipe 4. The conduit 10 may alternatively be connected at other positions such as at the mill 2 or the hopper 1. The mill 2 and the web 6 feed is started, whereupon ground coffee 16 passes into the tube (7) and together with some carbon dioxide is enclosed in packages 15 formed by successive operation of the sealing means 12. Excess gas is removed from the packages 15 by compression between plates 13 during sealing. A cut-off device may be combined with the sealing means to detach the individual packages.
