Title: Roof supported frame for ladders
Inventor: MOORE MICHAEL JOHN
IPC: E06C1/34
Filed: 1987-05-13
Abstract: A roof supported frame for ladders has two cross-shaped side members 10, 11. These are laterally spaced, substantially parallel and interconnected by a common rod 12. The cross-shaped members 10, 11 straddle a roof ridge 15 and have limb portions 13A, 14A which extend downwards over each side 16, 17 of the roof and limb portions 13B, 14B which diverge upwardly. A tie bar 18 connects these upwardly divergent limbs 13B, 14B once the limbs 13, 14 are in their proper angle of divergence on the roof. The depending limbs on one or both sides of the roof, i.e. limbs 13A, 13A or 14A, 14A, or both sets of limbs can be attached to the stiles 21 of a ladder 22. Alternatively, the limbs 13 or 14 can be replaced by a ladder 22 to the stiles of which the other limbs 14 or 13 and tie bars 18 are directly attached.   <IMAGE>

Title: Termination of mineral insulated electric cable
Inventor: POSTILL ALAN
IPC: H02G15/04
Filed: 1987-06-17
Abstract: A sealing pot 11 in the form of a metal sleeve 12 fits over a cable sheath 4 at the cut-back end of the cable 1 and, at the end of the sleeve remote from a closure disc 17, is so swaged or otherwise radially inwardly distorted throughout its periphery that the sleeve makes a sound mechanical and electrical connection with the sheath. Over a minor end part 15 of the length of the sleeve 12 at the end to be swaged, the internal radius of the sleeve is greater than that of the adjoining part of the sleeve. A nut 20 is screwed into a die 30 so as to compress an undeformed pot 11 and thereby distort it. <IMAGE>

Title: Clamping device
Inventor: STOLL KURT
IPC: B25B1/06
Filed: 1987-07-01
Abstract: The device comprises a mount (2,2') with a moving clamping jaw (5,5') thereon. The driven side of the clamping jaw is opposite to a supporting means (10,10'). Between the clamping jaw (5,5') and the supporting means there is a step- down thrust transmitting means with at least one transmitting member (16,16'). There is furthermore a transmitting rod (17,17') which displaces the transmitting member(s) as it moves into the step-down transmitting means, the transmitting member(s) then bearing against the supporting means (10) and acting on the clamping jaw so that the latter is shifted. <IMAGE>

Title: Phased array antenna system
Inventor: BRENNAN PAUL VICTOR
IPC: H01Q3/26
Filed: 1987-10-26
Abstract: A self-focussing phased-array antenna system for use with a combined intelligence signal (5) and pilot- signal (P) which may lie in the signal band. Each element (1, 3, 5, etc.) of the array has a phase-locked loop (21) which produces a signal ( theta s- theta v) having a fixed offset from the pilot/intelligence difference in both phase and frequency. Automatic pilot-phase compensation is thereby achieved both in poor S/N situations and for pilot frequencies within the signal band. <IMAGE>

Title: Recording discs and magnetic disc recording/reproducing apparatus
Inventor: KUTARAGI KEN
IPC: G11B7/007
Filed: 1988-07-01
Abstract: A record disk has a read-only track area and a writable track area in which a guard band of a sufficient width is formed between such two areas for prevention of erroneous writing into the read-only track area during data writing into the writable track area.

Patent GB-2217097-A (GB)
Title: Separation process and apparatus
Inventor: ISSEL WOLFGANG
IPC: G21C19/46
Filed: 1989-03-17
Abstract: In a process for the separation of uranium and plutonium as well as fission products from a nitric acid feed solution (fuel solution), the fuel solution is treated with an extraction agent by the contraflow process. The resulting charged extraction agent is treated with a washing solution and subsequently with a reducing agent for the separation of the uranium from the plutonium and from fission products not washed out in the contraflow process. In order to improve the separation of uranium from the fission products particularly technetium and obtain a cleaner uranium end product, the treatment with reducing agent is effected in one or more stages by the crossflow process instead of by the contraflow process or in addition a single- or multi-stage pretreatment with reducing agent by the crossflow process is provided, operative before the contraflow treatment with reducing agent.

Patent GB-2221610-A (GB)
Title: Apparatus for brewing coffee
Inventor: COUGHLAN MARTIN
IPC: A47J31/00
Filed: 1989-08-03
Abstract: A coffee brewing apparatus 10 comprises a water reservoir 11 with heating means and a coffee urn 12, the reservoir 11 having an inlet port 13 and an outlet port 22. The level of water in the reservoir 11 is primarily controlled by a level detector 19 and a water inlet valve 15. To brew coffee, the detector 19 is deactuated and water flows into the reservoir 11 which results in an overflow of water through the outlet 22. A second water level detector 20 closes the valve 15 when the water level reaches it. The water level falls below the second detector 20 and the valve 15 is opened again. Water from the outlet 22 flows over coffee in a filter located in the mouth of the urn 12. This cycle continues until a pre-set time has elapsed or the liquid level in the urn 12 reaches a third water level detector means 21. <IMAGE>

Title: Transceiver with noise immune voice operated transmission/reception switch
Inventor: WILSON COLIN ALEXANDER
IPC: H04B1/46
Filed: 1989-10-11
Abstract: A mobile transmitter receiver intended for simplex radio communication via a base station with another mobile transmitter receiver, the mobiles being intended for use in vehicles, has a microphone 1 connected to envelope detectors 3 and 4. The latter receive the same signal A, but detector 3 has faster time constants than detector 4, so that the envelope B produced as output is representative not only of speech signals but also of noise signals in the vehicle. The envelope detector 4 is slower acting and does not respond to normal speech signals and consequently only represents the slower varying vehicle noise. When these signals are subtracted from each other an envelope D representative substantially only of speech is produced. This output can be used to trigger the mobile into transmit mode, and permits hands-free operation in a vehicle environment. <IMAGE>

Title: Light emitting diode scanner
Inventor: METLITSKY BORIS
IPC: G06K7/10
Filed: 1991-06-06
Abstract: A portable scanning head emits and receives light from a light-emitting diode (10) to read symbols, such as bar-code symbols. The optics (12,18) within the scanner are operative for focusing a light beam (11) and the view of a light sensor (17) in different planes (13,22) exteriorly of a scanner housing. Imaging means are provided in the unit for imaging a viewing window. The viewing window has an area smaller than that of the scan spot. The system can employ an LED (10) as a light source and tolerate the relatively large-sized (on the order of millimeters) scan spot without sacrificing reading performance since the photodiode (17) "sees" only that portion of the scan spot visible through the viewing window.

Title: Extensible mast structure for an industrial lift truck.
Inventor: WARNER BARRY MICHAEL
IPC: B66F9/22
Filed: 1992-02-20
Abstract: Lift truck has a mast structure (10) comprising a fixed mast (11), a movable mast (13) and a load carrying structure (20) and lift means comprising a primary jack (25) for raising the load carrying structure up the movable mast and a secondary jack (33) for extending the mast structure. In operation, the secondary jack begins to extend before the end of the operational stroke of the primary jack, the remainder of the operational stroke of the primary jack assisting the secondary jack to extend the mast structure whilst continuing to raise the load lifting structure relative to the mast structure, the secondary jack thereafter completing its operational stroke. For this purpose, the movable part of the primary jack (shroud 25) engages stop means (17) on the fixed mast at an intermediate point in its stroke. The overlap in the operation of the two jacks effectively minimises any interruption or jerkiness in the upward or downward movement of the load lifting carriage. <IMAGE>
