Title: Space saving overhead power supply for electric railways in tunnels
Inventor: MACDONALD RAYMOND ALLAN
IPC: B60M1/34
Filed: 1987-02-18
Abstract: A supported overhead power suppy line for use in railway tunnels which are restricted in space or which require a resilient high capacity overhead power line for pantograph collection consists of a copper alloy box section rail supported by hinged insulators 4 from the tunnel roof and a contact line which is a flexible copper alloy wire 2 anchored to each end of a box section rail via tensioning means 3 so as to be tensioned to limit sag between the phosphor bronze spring hangers 7 (Figs 3 & 4) which suspend it from the box section rail. The combined box section in compression and the contact wire in tension are self compensating throughout a wide temperature range and thus do not need external tensioning devices. The box section rail assures high capacity, allowing single or double end feed over extremely long lengths without significant voltage drop. The contact wire has similar resilience to catenary supported systems. <IMAGE>

IPC: H04N11/24
Filed: 1987-05-08
Abstract: An HDTV video signal with 1249 lines per picture is transmitted over a transmission channel designed for 625 lines per picture by transmitting alternate samples of two lines of the 1249 line signal on a single line of the 625 line signal. An HDTV receiver can interpolate to give a 1249 line picture but a 625 line receiver will still receive a signal that is adequately compatible to give a display. <IMAGE>
Patent GB-2206453-A (GB)
Title: Laminated cores
Inventor: FRENCH WILLIAM GEORGE
IPC: H01F41/02
Filed: 1987-06-22
Abstract: A pack of laminations e.g. for a choke comprises laminations which are connected each to the next by only a single projection (4) which projects into a depression (3). The projection (4) has a height which is greater than 50% of the thickness of the lamination and the depression (3) has a depth which is greater than 50% of the thickness of the lamination. The depression (3) and projection (4) are produced by a projection punch (13) which cooperates with a die (14). The die has a lip which is either radiussed (r) or conical (C) and the punch (13) causes the metal of the lamination to be extruded past the lip into the die (14) whilst the depression (3) is being formed. The radiussed or conical lip allows the height of the projection and the depth of the depression to be greater than the normal 50% shear stress fracture depth/height. The laminations are punched and stacked in a single multi-stage progression tool. <IMAGE>

Title: Cant rail for curtain or similar-sided goods vehicle
Inventor: MCCULLAGH FRANK
IPC: B62D33/02
Filed: 1987-11-30
Abstract: A trailer or semi-trailer in which the cant rail 6 supporting the roof is so shaped and arranged as to be capable of functioning as a guide/support for the upper end of a movable support post 2 which extends down from the cant rail across the open side of the trailer or semi-trailer. This avoids the necessity of separate guide rails which can intrude into the load area. The cant rail 6 may comprise two inverted U-shaped members 4 with the closed side of one affixed in the open mouth of the other. The downward facing open mouth of the said one is provided with two inwardly projecting flanges 13 acting as guide rails for the roller wheels 26 of the upper part of the support post 2. As an alternative the two U-shaped members can be united mouth to mouth to form a box section, for use in vehicles whore intermediate support posts are unnecessary. The one member may still have its in-turned flanges. This facilitates the manufacture of standard parts which can be used for two different arrangements. <IMAGE>

Title: Duct surface testing for use in optical fibre transmission lines
Inventor: BUTLER DAVID
IPC: G02B6/44
Filed: 1988-06-20
Abstract: Apparatus for testing ducts for suitability for use in fibre blowing installations comprises a slider 5 that is projected along a sample of the duct 3 to be tested by a burst of air or gas. Velocity measurements are taken e.g. by two pairs of sensors 11, 12 as the slider decelerates due to frictional resistance in the tube and a friction or resistance value is obtained from the deceleration value determined from the velocity measurements. The slider is chosen to have a mass that exerts a force similar to the typical tension on a fibre package during blown installation, and the sample of duct is held in a curved track to present maximum resistance. A further sensor 13 may be provided to help determine the power required by the burst of air, the aim being for the slider to come to rest between sensors 12 and 13. <IMAGE>

Radiation in the radio frequency band may be used. <IMAGE>
Patent GB-2225062-A (GB)
Title: Dampening pressure shocks in pump outlets
Inventor: BRADE COLIN EDWARD
IPC: F16L55/05
Filed: 1989-11-03
Abstract: The dampener 10 comprises a one-way valve 12 operable in response to a drop in pressure at the pump outlet 14 to introduce compressible gas into the pump fluid 16. The compressible gas absorbs shocks caused by the drop in pressure and the resultant back flow of fluid. The pumped fluid including any shock absorbing gas passes from 16 through a one- way valve 20 into a reservoir 22 where the liquid and gas separate out. The liquid passes out of the reservoir through an outlet 18 and the gas is recirculated through a pipe 28 to the valve 12. Gas losses can be replenished through a valve 32. <IMAGE>
Patent GB-2229716-A (GB)
Title: Rooting gels
Inventor: RAINBOW ARNOLD
IPC: A01G7/04
Filed: 1990-01-31
Abstract: Containers including translucent aqueous rooting gel, wherein the end portion of a plant cutting inserted into the gel is screened from light of certain wavelengths, exhibit improved agronomic properties eg quicker and/or more reliable rooting. Particularly good results are obtained when the end portion of the plant cutting is illuminated by green light. Screening may conveniently be achieved by making the container from a coloured translucent material or by using a green gel. Results are improved still further by the addition of indolebutyric acid or a salt thereof to such gels.

Title: Waste toner collecting device for an image recorder
Inventor: OKAMOTO KEIJI
IPC: G03G21/12
Filed: 1991-06-03
Abstract: A device incorporated in an electrophotographic image recorder for collecting toner particles, paper dust and so on which are removed from a photoconductive element by a cleaning device. The collecting device 50 is constructed independently of the cleaning device 32. In a portion where the collecting device and cleaning device are connected to each other, a first and a second shutter 60, 86 which open and close respectively an opening formed through the cleaning device 62 and an opening 84 formed through the collecting device cooperate with each other. When the collecting device 50 is connected to the cleaning device 32, the second shutter 86 unblocks the associated opening 84 before the first shutter 60 does so. Conversely, when the collecting device 50 is disconnected from the cleaning device 32, the second shutter 86 blocks the associated opening 84 after the first shutter 60 has done so. <IMAGE>

Patent GB-2259376-A (GB)
Title: Voltage and current reference source
Inventor: WILD ANDREAS
IPC: G05F3/24
Filed: 1991-08-24
Abstract: The supply voltage rejection of a resistor-fed R1 diode-coupled MOSFET 4 voltage source is improved by inserting a resistor R2 in the drain circuit such that increased gate voltage due to increased drain current is counteracted by an increased voltage drop across R2. The output voltage available at the drain of MOSFET 4 can be made invariant to supply fluctuations by choice of R2, in which case the output voltage becomes twice the threshold voltage of MOSFET 4. This allows the threshold voltage to be determined by varying R2 and the supply voltage, then observing output flatness. A current source MOSFET 6 may be controlled by the output voltage. <IMAGE>

Title: Video signal interpolation and scanning line doubling
Inventor: SONG DONG-IL
IPC: H04N11/20
Filed: 1992-01-22
Abstract: An input digital video signal is applied to vertical bandpass filter 20 to produce a vertical high resolution component signal. This is subtracted 30 from the input video signal (passed through matching delay 10) to produce a vertical low resolution component signal. The vertical low resolution component signal is interpolated 40 eg by linear or slant correction interpolation and added 60 to the vertical high resolution component signal which has undergone "0" insertion interpolation 50. The output of adder 60 is then passed to a scanning line doubling circuit and displayed by progressive scanning. Deterioration of the vertical resolution is prevented by the separate treatment of low and high resolution components of the video signal. <IMAGE>
