Patent GB-2152313-A (GB)
Title: Dc-ac converter
Inventor: BRADFORD RAYMOND ERNEST
IPC: H02M3/156
Filed: 1984-11-08
Abstract: A low voltage converter is operative to up-convert an unstabilised input voltage of the order of one volt to a much higher output level, typical about 9 volts. A current transformer having three windings is used, one winding of which generates from a primary winding a base current for a switching transistor. The third winding reverses the magnetic flux when the transformer core saturates, thereby forming an oscillatory cycle, the mark- to-space ratio of which determines the voltage step-up ratio. Once the converter has generated a sufficiently high output voltage, a control circuit can take over to produce a precisely controlled output level. <IMAGE>

Title: Using traffic generated airflow to generate electrical energy
Inventor: MCSHANE DEREK WILLIAM
IPC: F03G7/08
Filed: 1984-12-12
Abstract: Tunnels are constructed on roads, motorways, rail or underground rail systems. The wind force created by traffic going through the tunnels drives a system of fans and associated generators built into the tunnels. A tunnel system can be adapted, and built from a single type of unit for roads, and carriageways, or as a conglomerate of fans and generators for motorways and rail systems. A tunnel may be provided with re-charging facilities, for electric vehicles enabling them to travel on motorways and to travel much further distances. The energy can be used for factories, farm projects, and small towns, anywhere in the world, where a cheap source of energy is required. The tunnels can be set up on any busy road, rail or underground system. Since traffic uses road and railways night and day, energy can be collected 24 hours a day 365 days a year.

Patent GB-2180112-A (GB)
Title: Transparent tone-in band transmitters receivers and systems
Inventor: MCGEEHAN JOSEPH PETER
IPC: H04L27/02
Filed: 1986-07-29
Abstract: In transparent tone-in-band communication systems a notch in the frequency band is usually formed and then the resulting spectrum is translated in frequency to an intermediate frequency range as part of the transmission process. In a transmitter of the present invention a more simple arrangement is used in which the notch is formed directly in an intermediate frequency range by using mirror filters 11a and 11b to divide an input signal into two portions and supply respective mixers 12 and 14, each having one output sideband in the intermediate frequency range. The mixers 12 and 14 receive different reference frequencies from oscillators 27 and 28. The mixer outputs are supplied to a summing circuit 16 whose output is passed to a band pass filter to remove the unwanted sidebands. The original frequency spectrum is restored at the receiver (Figure 3) by mixer processes of shifting the two selected sidebands similar to, but the inverse of, those used in the transmitter. In modifications (Figures 5 and 6) one of the portions from 11a and 12a is fed to the summing circuit 16, the other portion from 116 is fed to the summing circuit 16 via two mixers (35, 38 or 57,58) and the other portion from 12b is fed to the summing circuit 16 via two mixers (44,47) or a frequency converter (55'). <IMAGE>

Title: Motion detent arrangement
Inventor: MANK JAMES LEON
IPC: E21B33/038
Filed: 1988-02-11
Abstract: A motion detent arrangement 14' for inhibiting unwanted axial displacement of an elongate tubular core member 10 relative to a surrounding sleeve member 11 by an extraneous axial force has detent teeth 16 formed on the core and toothed detent dogs 17 carried by the sleeve, the dogs being biased towards the core to mesh with the teeth and retractable therefrom by a cranked operating lever 20 pivotally mounted with an arm 24 extending radiaily of the sleeve. Application of an operating axial force between the core member e.g. a pipe, hose or cable and operating lever arm firstly removes the detent and then acts to displace the sleeve in relation to the core. This detent actuation enables a single acting source of force 26 to provide both detent release and displacement functions. Preferably the operating lever arm 24 lies alongside a flange 29 which limits lever displacement and permits large forces to act on the sleeve. <IMAGE>
