Title: Window friction stay.
Inventor: LANAWAY RONALD PHILIP
IPC: E05D15/30
Filed: 1991-07-03
Abstract: In a window friction stay, tracks 10 are fixed to opposed members of a window frame and a window sash is fixed at opposed edges to respective members 16, forming part of a link arrangement in a conventional manner. At one end each track 10 is closed by a member 30 providing upstanding cam surfaces 36, 38 facing towards respective opposite sides of the track 10. A guide 48 is pivotally mounted on the member 16 by means of a rivet 50 to have limited pivotal movement in either direction. On closing of the window from one side, the guide 48 initially engages with the cam surface 36 by way of a radiussed point 60, and can pivot to then bring a guide surface 56 in to face to face contact with the cam surface 36. Subsequent engagement of a guide face 58 with the other cam surface 38 guides the link arrangement into a correctly aligned closed position. <IMAGE>

Title: Decoding of composite television signals
Inventor: CROLL MICHAEL GEORGE
IPC: H04N/
Filed: 1991-08-21
Abstract: A broadcast system is provided in which the effects of differential distortions on composite television signals are reduced. At predetermined intervals, the broadcast signal includes a test signal having high frequency components at at least three average video signal levels. In a suitably equipped receiver, following demodulation by the receivers vision demodulator (20), a test signal is identified by a test signal detector (34). Measurement apparatus (24) then measures the distortion of the test signal at a number of different average video signal levels, calculates the correction required to minimise the effect of distortion at each measured signal level, and stores the corrections in a memory (28) at address locations derived from the demodulated signal by a filter circuit (32). The stored corrections are applied to an interpolator (40) which derives further corrections for other average video signal levels, the derived corrections being applied to subsequently received television signals by a controllable equaliser (38). <IMAGE>

Title: Displacement measurement apparatus
Inventor: JOHNSTON JAMES STEWART
IPC: G01D5/347
Filed: 1991-10-17
Abstract: Displacement measurement apparatus (1) measures the position of a reading means (4) relative to a coded track (2) which carries a sequence of code elements (5). The track is encoded with a binary sequence such that reading a binary word at any position along the track uniquely identifies its position. The binary word is remotely sensed by a decoding means (18) via a fibre optic link (12). Position information is encoded optically by the reading means (4) using an interferometer to frequency modulate the transmitted light and the decoding means (18) has a second interferometer to analyse received light and produce an electrical output representing the binary word. <IMAGE>

Title: Automatic umbrella safety catch system
Inventor: LIU FU-TIEN
IPC: A45B25/14
Filed: 1992-04-29
Abstract: A full self-opening and partial self-closing umbrella comprising an upper rib linkage runner (4) and a lower latch runner (5) slidable on a collapsible centre-post (2) has an arrangement of safety catches to prevent accidental opening. When the centerpost is collapsed against the bias of the extension spring (10), the rib linkage and latch runner are latched by a primary latch hook (72) on a lever (7) urged by a spring in position adjacent the umbrella's handle. Also, the umbrella includes on the lever (7) a safety hook (73) that engages the linkage runner (5) to prevent opening of the centerpost if the umbrella's push button (6) is inadvertently pushed when the umbrella is closed and the umbrella's cover is wrapped with a closure strap. The safety hook prevents the umbrella from opening prematurely when the closure strap is released. A secondary latch hook (71) prevents inadvertent opening of the ribs and cover when the cover is being furled and strapped. <IMAGE>

Title: Optical analysis system and positioning apparatus therefor
Inventor: COLEMAN CLIVE IAN
IPC: G01N21/86
Filed: 1992-12-02
Abstract: An optical analysis or processing system for use, for example, in the analysis of microscopic spots of material by their effect on a very fine polarized beam of light (e.g. FPIA). For multiple "spot" analysis the spot samples are disposed on a substrate in predetermined relation with an optical pattern, bars, chevrons, etc. The substrate (1) is mounted in the path of the fixed and focused beam with three degrees of freedom of movement. A video camera (9) records the optical pattern very accurately and controls the substrate mounting to position a selected sample spot at the beam focus. Multiple and rapid sample analysis can thus be performed.

Title: Wheel examination apparatus
Inventor: HIRANO AKIRA
IPC: G01M17/06
Filed: 1993-08-20
Abstract: Apparatus for examining a wheel (1) of a vehicle is provided. A support roller assembly (30) supports a wheel (1) both for translational as well as rotational movement in a plane when unlocked. A wire (35) extends between the free end of the reciprocatable rod (34b) of a cylinder actuator (34a) and the support roller assembly (30). When the rod (34b) is located at its extended position, the wire (35) is slack to establish a static examination mode of operation, in which the support roller assembly (30) can move freely in a plane without constraints. Under this condition, the static characteristic of the wheel is measured and adjusted, if necessary. When the rod (34b) is located in its retracted position, the wire (35) is under tension, and the cylinder actuator (34a) is operatively coupled to the support roller assembly (30) whose movement is controlled by the wire (35). Thus, a dynamic examination mode of operation is established. In this state, the wheel (1) is rotated and the dynamic characteristic of the wheel is measured and adjusted, if necessary. <IMAGE>

Title: Transponder
Inventor: CLARKE DAVID JOHN
IPC: G01S13/82
Filed: 1993-12-21
Abstract: A transponder transmits a reply signal at a radio frequency determined by the frequency of a received interrogation signal which is an amplitude modulated by a wake-up signal causing the transponder (used for meter reading) to switch from a dormant to an active state and a receiver circuit to be switched from AM to FM. The receiver circuit has amplitude demodulators 118, 120, 122 feeding a summer 124 and fed from respective cascaded IF amplifiers 106, 112, 116. The receiver characteristics are chosen so that the first demodulator 118 will never be overloaded so that the wake-up signal can still be detected even if a strong AM signal overloads demodulators 120, 122. <IMAGE>

Patent GB-2303255-A (GB)
Title: Magnetic reluctance motor
Inventor: ASPDEN HAROLD
IPC: H02K15/02
Filed: 1995-07-07
Abstract: A magnetic reluctance motor has a rotor which comprises several laminated rotor sections 19 axially spaced along a supporting spindle 1. Between these rotor sections there are permanent magnets 18 or ferromagnetic ring cores with rotor excitation windings serving as electromagnets. The rotor sections have salient poles interacting with a set of elongated stator cores 17 mounted parallel with the axis of the spindle and around which there is a magnetizing winding 16 which powers the motor by current pulses which promote magnetic flux switching H affecting the magnetic attraction between the stator and rotor poles. The motor has an efficiency dependent upon the recovery of inductive energy fed to the magnetizing winding and a dual motor combination is described in which such recovery involves energy exchange between the two motors. A primary feature is the use of a solenoidal magnetizing winding which determines the polarization of all the stator cores in the same motor.
