Title: An element with several stable structural shapes
Inventor: DATON-LOVETT ANDREW JAMES
IPC: E04C2/40
Filed: 1990-06-25
Abstract: An element which can be held in more than one stable structural shape comprises a tensile layer arranged to be relatively inelastic longitudinally. This layer may be formed from a plurality of parallel bands (2) of carbon fibre. A plurality of compressive blocks (4) are attached to the bands (2) to extend in rows along the bands. Furthermore, a plurality of transversely extending, inelastic bands (10) are also fixed to the blocks (4). If the bands (10) are curved transversely of the longitudinal extent of the element they are tensioned against the action of compressive forces produced by the blocks (4). This means that any structure formed from the tensioned element exhibits good structural rigidity.

Title: Tile clips
Inventor: POWELL JEFFREY BRIAN
IPC: E04D1/34
Filed: 1991-01-18
Abstract: A tile clip (15) includes a plastics moulding having a generally planar body portion (16) provided at one end with a jaw within which an edge of a tile can be received, and an elongated slot (22) the side edges of which are of saw-tooth formation to provide a ratchet which cooperates with a locking member (26) which fits within the slot (22) and can be nailed to a support beam. After the locking member (26) has been nailed in position, the body portion (16) of the clip (15) is slid relative to the locking member (26) until the edge of the tile fits in the jaw. The action between the ratchet and the locking member (26) then prevents movement of the body portion (16) in the opposite direction and holds the tile securely in position. <IMAGE>

Title: Separator/folder bag machine
Inventor: HATCHELL PETER
IPC: B65H35/10
Filed: 1991-11-07
Abstract: A pair of high speed separation rollers 44, 46, intermittently nip a continuous plastic web 12 travelling at relatively lower speed to separate individual plastic bags at perforations formed in the web. Upper roller 46 is periodically lowered into nip engagement with roller 44 by a motor driven linkage (not shown) which includes an eccentric. A pair of parallel, wide belts 96, 98, and a pair of similar, overlying bolts 100, 102 engage both sides of the separated bags 22 and transport the bags to a plurality of folding stations 34, 36, 38. Air jets 74, 76, 78 controllably direct the bags through pairs of nip rolls 62, 64, 66 to fold the bags along predetermined fold lines. Sensors in the folder/separator sense abnormal conditions and deactivate particular fold stations to reject improperly formed bags. At the discharge end of the separator-folder, two-speed rollers 84. 86 slow the folded bags to facilitate downstream handling. A stacker and indexing conveyor 30 automatically stacks predetermined numbers of folded bags, aligns and compresses the bags to form an easily handled stack, and conveys the formed and compressed stack to downstream apparatus for further handling. <IMAGE>

Title: Semiconductor switching device with quantised resistance
Inventor: WILLIAMS DAVID ARFON
IPC: H01L29/80
Filed: 1991-11-27
Abstract: A semiconductor switching device comprising a nanostructured conduction region (10) that for particular operating conditions exhibits a resistance which can be at one of a plurality of discrete levels, and a control electrode (11) for switching the resistance of the region between the discrete levels selectively. The device includes a GaAs/GaAlAs heterojunction which can generate a 2DEG constrained by parallel gate electrodes 6a, 6b which have protrusions 7, 8 forming a quantum dot 10 in the channel. Ohmic contacts 12a, 12b are formed at opposite ends of the channel and the device also has a back electrode. A control potential applied to the electrode 11 alters the electron occupancy of the quantum dot 10 and switches the resistance of the channel between quantised levels. <IMAGE>
Patent GB-2265482-A (GB)
Title: Security system data transmission
Inventor: TIBBETTS ROBERT JOHN
IPC: B60R25/10
Filed: 1992-03-28
Abstract: A motor vehicle alarm system has a radio transmitter convenient for carrying by the driver of the vehicle, and a radio receiver suitably located inside the vehicle. The transmitter can be operated remotely to transmit a numerical rolling or dynamic code whereby a different code is transmitted each time. Such a code is determined by the use of a preselected security number and a randomly selected step number, the latter being altered in each transmission. The transmitter uses the security and step numbers in an algorithm, and the receiver, provided with the security number, can use the latter and the code in a reverse algorithm in order to reproduce the step number. Comparison with a previously stored step number is then made by the receiver to prevent a response to an unauthorised transmission.

IPC: H03C3/00
Filed: 1992-06-13
Abstract: This invention relates to a frequency modulator (Fig. 2), such as for non-return-to-zero (NRZ) FM Modulation. A sample and hold element (12) is provided having an analog input for receiving an analog input signal, a control input (18) for receiving first and second control signals and an output. It is arranged to pass the analog signal to its output when the first control signal is applied to the control input and to provide a nominal middle voltage (u0) on its output when the second control signal is applied to its control input. Binary modulation elements (20, 21, 22) are provided, arranged to commence binary modulation of the output about said nominal middle voltage when said second control signal is applied to said control input. The arrangement avoids disturbance of voltage stabilising circuitry associated with the analog modulation portion by the binary modulation signal. <IMAGE>

Title: Fire alarm system in appliances
Inventor: MALIK SOHAIL
IPC: G08B17/10
Filed: 1993-02-26
Abstract: Appliances such as washer-driers and tumble driers use heating elements and are prone to catching fire. Invariably, such appliances are installed in or close to kitchens where smoke detectors are impractical due to cooking fumes. Consequently, a fire generated in the said appliances may not be detected until smoke has resulted in substantial quantity to activate a distant smoke detector. This delay increases the chances of the fire becoming serious before detection and increases the risk to life and property. A dedicated smoke sensor unit 10, 15 installed proximate the appliance and wired to a isolating relay unit 23 housed in a module that plugs into the mains socket 13 enabling the said appliance power lead in turn to be connected into the mains circuit via the said module, a remote alarm unit is connected through the mains wiring and the system draws power from the mains supply to drive each unit. Alternatively, the system can be battery powered and use radio frequency technology. When smoke is detected in the body of the said appliance the remote alarm unit, battery or mains powered, is activated by coded signals and the circuit simultaneously isolates the mains power to the said appliance whilst activating fire extinguishers 24 when fitted. <IMAGE>
