Abstract: A bundle of helically wound metal tubes 2 is made by rotating turntable 7 and hauling off the tubes by capstan 4. Outer reels 1 unwind in cradles which are each rotated by chains about an axis parallel to the rotation axis of the turntable. Tube guides 6 are rollers. Spool rotation is braked, by one of three different described systems, so that tension in the individual tubes >/= 2Yd<2>t, DIVIDED D where Y is the yield stress of a tube, d its outside diameter, t its wall thickness, and D a diameter to which the tube is bent around a spool. The tubes are wound around a central tube. Winding pitch is constant, with the bending stress of an outermost tube equalling between one half and one times its yield stress. <IMAGE>

Title: A railway vehicle for carrying trailers
Inventor: PRIOR ALAN JOHN
IPC: B61D3/18
Filed: 1993-04-01
Abstract: A railway vehicle for carrying trailers or other road vehicles has a main frame member 2 extending between two undercarriages 10. Decks 8 extending from the main frame member 2 support the trailer's wheels. In order to reduce the overall height of the loaded vehicle, the main frame member 2 extends through the space between the trailer's wheels and under the axles of the trailer 3. The decks 8 can be fixed to the frame member 2 or alternatively can adapted so as to be movable relative to the frame member 2 in order to aid in the loading of the trailer 3. In another embodiment the trailer 3 is supported directly on the main frame member 2 with the unsupported road wheels astride the frame member 2. For loading the trailer 3, the frame member 2 can also be detached from the undercarriages 10. <IMAGE>

Title: Dielectric porosity change immunoassay
Inventor: ATHEY DALE
IPC: C12Q1/00
Filed: 1993-05-29
Abstract: A homogeneous immunoassay in which the detectable signal is produced by the effect of a reactive or catalytic species which, during the course of the reaction of the ingredients of the immunoassay, becomes immobilised at or very near to a dielectric layer covering an electrode. Said reactive or catalytic species directly or indirectly effects a reaction with the said dielectric layer wherein the dielectric layer becomes porous causing a measurable change in electrical properties at the electrode surface. The electrical property may be resistance or capacitance. The dielectric layer may be of a pH-sensitive polymer, panticularly cellulose acetate hydrogen phthalate and the species preferably causes a change in pH. The species may be urease.
Patent GB-2281835-A (GB)
Title: Phase locking system for video signals
Inventor: HUDSON JOHN
IPC: H04N5/93
Filed: 1993-09-08
Abstract: A system for synchronising an input video signal having an asynchronous frame sync frequency comprises the step of temporally interpolating output fields from the input fields, at the appropriate temporal positions. A specific embodiment disclosed, allows the input signal to be stored in a video memory at the asynchronous frame rate and read from memory at the asynchronous frame rate. The drift in write and read sync rates can cause frames to be skipped or repeated and this effect is compensated for by temporally interpolating the fields in a transition period when this effect occurs. Interpolation can be motion compensated. <IMAGE>

Patent GB-2289394-A (GB)
Title: A ring network system
Inventor: TATTERSALL DAVID
IPC: H04L12/423
Filed: 1995-05-09
Abstract: A ring network system has at least one node M which acts as a master or sender node to transmit an outgoing signal (O.S.1) having a relative address determined according to the relative location of the addressee node in the system. As the outgoing signal passes through each node in turn, it is changed and a node recognises that it is the addressee node if the relative address has a predetermined common addressee value. The addressee node generates a return signal (R.S.1) with a node identifier which is transmitted in the opposite direction to the outgoing signal and the sender node ensures that this is received for a valid poll. The master node M may automatically configure itself by retrieving the identifier of all nodes in response to outgoing signals. This allows nodes to be easily added or deleted. Each node on the return path adds data which it has captured together with its identifier so that data may be captured from all nodes between the sender node and the addressee nodes. A node M may transmit outgoing signals alternately in opposite directions in a manner whereby the addressee nodes are selected so that each communication link 3 - 8 is omitted in sequence and fault diagnosis takes place. <IMAGE>

Title: Reducing turbocharger lag
Inventor: ALFORD ADRIAN GRAHAM
IPC: F02B37/10
Filed: 1995-06-10
Abstract: For reducing turbocharger lag when increased power is required from a so-equipped engine 7, operating at part load, its compressor 8, is provided with nozzles or directing devices 3, designed to increase the speed of the rotor (9)(figures 1 and 2) or to rotate the charge entering the compressor. The devices 3, are supplied by recirculating compressed charged, via a distributor valve 2. A heat source such as a heat exchanger 4, (with a shunt 5, controlled by a distributor valve 6) using waste heat from exhaust gases, can heat the recirculating charge, thereby increasing the energy of the recirculated charge to further increase the rotational speed of the rotor or charge. Compressed air supplied to the engine 7, may pass through a cooler 10. The tendency of the turbocharger to surge may also be reduced.

Title: Washing machine motor control
Inventor: PAYNE THOMAS ROY
IPC: D06F34/08
Filed: 1993-08-20
Abstract: A washing machine has an electronically commutated motor which is brought to a halt by: generating a speed control signal which brakes the motor, repeatedly sensing motor speed, and each time the sensed speed has fallen by a predetermined increment, generating a new speed command signal. Preferably, when speed is down to a certain level, one phase of the motor is energised continuously until the motor stops. The speed increment may be 20rpm or 100rpm, depending on whether the motor is being used for washing or spinning.

Patent GB-2297863-A (GB)
Title: Gas discharge device
Inventor: PIRRIE COLIN ARCHIBOLD
IPC: H01J17/30
Filed: 1996-02-08
Abstract: A device suitable for switching large currents includes, within a gas filled envelope, a anode 1, electrodes 2 and 3 and a thermionic cathode 4. Initially, the device holds off a voltage until a triggering pulse is applied to electrode 3. This causes a electron current to be established between the thermionic cathode 4 and anode 1. When the current reaches a sufficiently large value, further conduction through the device occurs via current drawn from the surface of the electrode 2 in cold cathode mode, bypassing the cathode 4.

Title: A method for increasing capacitance of a semiconductor device
Inventor: SUN SHIH-WEI
IPC: H01L21/02
Filed: 1996-12-04
Abstract: The capacitor, e.g. of a DRAM cell, is formed by depositing a first layer of hemispherical-grained silicon (HSG-Si) 42 on a substrate such as a layer of doped polysilicon 40 e.g. by LPCVD. Growth of the first layer of HSG-Si is interrupted and then a second layer of HSG-Si 46,48 grown independently of the first layer. In one aspect, growth of the first layer of HSG-Si may be interrupted by either cooling the deposition substrate or stopping deposition for a period of time. The interruption of the growth of the first layer is sufficient to ensure that the reinitiated growth initiates in a manner that is independent of the first process. In a different aspect of the invention, growth of the first layer may be interrupted deposition of amorphous silicon or by removing the substrate from the deposition system and performing an etch back operation. After the etch back operation, the substrate is reintroduced to the deposition system and a second layer of HSG-Si is grown on the etched surface. This textured silicon structure forms the lower electrode of the DRAM capacitor.
