Patent GB-2005818-A (GB)
Title: Headlights for vehicles
IPC: E05D1/02
Filed: 1978-09-20
Abstract: A vehicle headlight arranged for tilting adjustment has mounting means comprising a pair of spacer elements (5) that define the pivot axis for that adjustment. Each spacer element has enlarged ends (10, 11) providing a large area bearing surface (8,9) for the headlight reflector (2), or a reflector carrier, and its connection to the vehicle body (7) respectively, and a flexible flattened web (12) joining said ends. By locating the webs of the respective elements with the major dimension of their cross-sections substantially coplanar it is possible to effect tilting adjustments without producing large forces in the spacer elements that might cause deformation of the headlight reflector. <IMAGE>

Title: A machine for producing chenille yarns
IPC: D04D3/00
Filed: 1979-08-08
Abstract: A machine for producing chenille yarn has a winding member 45 on which turns E1 of effect yarn are formed. A rotating disc-shaped cutter 60 can be moved into an operative position to cut the turns on the winding member into individual lengths of effect yarn for forming conventional chenille yarn.

Patent GB-2038114-A (GB)
Title: Apparatus and method for generating waveforms which are particularly suitable for a PWM- driven motor
IPC: H03K/
Filed: 1979-12-11
Abstract: A triangle waveform having substantially linearly sloped, gradually increasing and decreasing edges and having a frequency nf is generated from an n-phase sine wave signal, each phase having a fundamental frequency f. A segment of any of the n-phases of the sine wave is detected when that segment is within a predetermined angular amount from a reference crossing level, such as the zero crossing of the sine wave signal. Successive ones of the detected segments are selected to synthesize the triangle waveform. In the preferred use of this invention, the triangle waveform is compared to a reference signal, such as the sine wave signal from which the triangle waveform is generated, this reference signal having a controllable frequency and amplitude. Pulse transitions are generated at the intersection of the triangle waveform and each of the respective phases of the reference signal. In one embodiment of this invention, the frequency of the triangle waveform is increased by an amplitude- folding technique wherein the triangle waveform (of frequency nf) is folded about a pair of equal but opposite folding levels whenever the triangle waveform reaches either of these levels, so as to produce an amplitude-folded triangle waveform of frequency mf and of peak levels determined by the folding levels.

In unconsolidated ground the store can be constructed by filling the hole with drilling mud as the excavation proceeds, installing supporting and/or insulating panels 3a, 3b, 3d and then adding the binder to consolidate the drilling mud to form the heat store. The panels may comprise a layer of low heat conductivity sandwiched between layers of steel or reinforced concrete. <IMAGE>
Patent GB-2071252-A (GB)
Title: Spin dryer safety device
IPC: F16P3/08
Filed: 1981-02-04
Abstract: A control circuit for a spin dryer has a triac (24) in the supply to drum motor (8) and controlled by a flip-flop (34). An oscillator-driven counter (21) emits a signal when a prescribed count is reached, to reset flip-flop (34) and de-activate the triac. A pulse generator (10, 32, 33) driven by the motor generates a train of pulses at a rate dependent on the motor speed and delivers them to a monostable flip-flop (19) having a resetting time in excess of the pulse interval corresponding to a prescribed low speed of the motor. When, during braking, the motor speed falls below the prescribed value, the flip-flop (19) resets between successive pulses and operates an unlocking electromagnet (31) which unlocks the lid of the spin dryer only when the spin dryer drum 7 has virtually stopped to ensure safety of the operative. <IMAGE>

Patent GB-2079914-A (GB)
Title: Drying webs
IPC: F26B3/20
Filed: 1981-04-16
Abstract: A wet web (4) and a drying felt (5) are enclosed between two air-tight surfaces having a good thermal conductivity. The surface in contact with the web is heated and the surface in contact with the drying felt is cooled by cooling water so that water is evaporated from the web into the felt and condensated in the felt. After the condensation the felt is separated from the dry web. The cooling water is discharged from the drying process at a temperature of 60 DEG -100 DEG C so that the enthalpy of the discharged cooling water can be utilized economically e.g. for heat pumping. The discharge temperature of the cooling water is controlled by adjusting the inlet temperature and/or the flow rate of the cooling water supplied to the drying process. <IMAGE>
