Title: Fastener for casement windows
Inventor: JACK MICHAEL STUART
IPC: E05C1/06
Filed: 1983-12-01
Abstract: A fastener for a casement window or door comprises a base (1) which is adapted to be secured to a window or door, a handle (11) pivotally mounted on the base (1) and a linearly movable bolt (5) mounted in a slot (4) in the base (1) and adapted to be engageable with a surrounding frame of the window or door. Pivotal movement of the handle (11) about a pivot (12) is converted into linear movement of the bolt (5) by means of a pin (16) mounted on the handle (11) at a location spaced from the pivot axis (12) of the handle and a slot (8) formed in the bolt (5), the pin (16) being located in the slot (8) whereby pivoting movement of the handle (11) in one direction causes the pin (16) to engage one side of the slot (8) to move the bolt (5) in one direction and pivoting movement of the handle (11) in the opposite direction causes the pin (16) to engage the other side of the slot (8) to move the bolt (5) in the opposite direction. The pin (16) is provided with a screw-thread which is engaged with a screw-threaded bore in the handle (11) whereby the pin (16) can be screwed into a bore (9) in the base of the slot (8) in the bolt (5), when said bore (9) is aligned with the pin (16), in order to lock the bolt in position so that the window or door to which the fastener is secured cannot be opened. <IMAGE>

Title: Blended yarn
Inventor: GOLDENSTEIN BERTRAND
IPC: D02G1/18
Filed: 1984-01-11
Abstract: A high bulk olefin blended yarn includes selected percentages by weight of olefin fiber with naturally occuring fiber such as cotton or wool, which are cut and blended together to form a staple thereof which are then spun and twisted in a conventional manner to form the blended yarn, the yarn becoming a high bulk yarn under controlled high heat levels. Preferably, 60% to 85% of cotton or wool by weight and 40% to 15% of olefin by weight are blended together. In a modified form, 20% to 40% by weight of polyester can replace a like amount of weight of the cotton or wool to reduce the cost thereof. The olefin in the fabric formed from the high bulk olefin blended yarn produces a wicking action capable of transmitting moisture from the wearer's body.

Title: Transmission device assembly for vehicle
Inventor: CAMPOPIANO FELICE
IPC: B62M6/60
Filed: 1984-09-21
Abstract: A transmission drive assembly for an electrically assisted or powered vehicle e.g. a bicycle, comprises a drive plate 1 and adaptor gear 4. This assembly is located on the outer casing of a change-speed gear hub 3 fitted to a wheel 2 by means of location using its three inner teeth and held in position by a circlip. The assembly has a clutch unit 7 driven by an electric motor 6 and coupled to the drive plate 1 by a poly-V belt 12. The clutch unit 7 rotates in one direction when powered by the electric motor 6, and when the clutch unit is rotated faster than the electric motor shaft the clutch unit disengages the drive to the motor. This arrangement permits use of the variable ratios available in the hub gear 3, e.g. higher the ratio of the hub gear the greater the torque output of the electric motor. The adaptor gear 4 is detachable from the drive plate 1, and carries a sprocket connected by a chain and further sprocket to rider-operable pedals. <IMAGE>

Patent GB-2163575-A (GB)
Title: Improvements in or relating to electronic timepieces
Inventor: YABE HIROSHI
IPC: G04F5/06
Filed: 1985-06-28
Abstract: Rate change in a quartz crystal timepiece due, for example, to aging of a capacitance used for correcting the frequency-temperature characteristic of the crystal oscillator of the timepiece, is corrected by dividing the oscillator output signal to provide a minimum rate adjustment unit signal and a rate adjustment timing signal. A rate adjustment step width signal consisting of a number of minumum rate adjustment unit signals is predetermined for all of the timepieces in a production run. The number controls the repeated counting of unit signals to produce a series of step width signals. The rate adjustment required for correct timekeeping is determined as an integral number of step width signals. The latter number is set into a second counter in the timepiece to generate a rate adjustment signal. The rate adjustment signal controls the duty cycle of a switch which adds reactance to the crystal oscillator circuit to effect the rate change.

Title: Ignition systems for internal combustion engines
Inventor: DAWSON JOSEPH GIBSON
IPC: F02P3/06
Filed: 1985-12-19
Abstract: The ignition system comprises a high tension supply 5 and a distributor for sequentially connecting the high tension supply to each of a series of spark plugs fitted to the engine.

The switch supplies a signal to a control input 12 of the H.T. supply to turn on the high tension supply for a predetermined angular rotation of the distributor for each spark plug. A train of high voltage pulses is delivered to each plug. In a modification the switch 9, 11 is replaced by an optical device. <IMAGE>
Patent GB-2187312-A (GB)
Title: Switching bridge circuit
Inventor: RICHARDSON MICHAEL JULIAN
IPC: H02M7/797
Filed: 1986-02-06
Abstract: A bridge circuit for controlling the supply of current to a load 11 from a d.c. source 13 includes four semi-conductor switches Q1 to Q4 each in parallel with a diode D1 to D4. The voltage across the load 11 is fed back at 18 to be compared at 19 with the instantaneous value of an input wave form 12 of desired shape, and any error between the desired voltage and the actual voltage produces an error signal which controls by logic means a pulse width modulator for appropriate control of the switches Q1 to Q4. If the error is positive the circuit will alternately draw current through the load from the supply and allow the current to free wheel in the bridge circuit, whereas if the error is negative the circuit will alternately arranged for current in the load to be regenerated to the supply and to free wheel in the bridge circuit. Fairly accurate tracking of the input wave form can be achieved. The load 11 may be a linear motor driving a reciprocating compressor. <IMAGE>
