Patent GB-2226701-A (GB)
Title: Electrical switch
Inventor: SHE WILLIAM YUNG-LEE
IPC: A63H1/24
Filed: 1988-12-30
Abstract: An electrical switch including a contact member which comprises a coil spring (22), said coil spring (22) being resiliently deformable between a non-contacting or OFF position and a contacting or ON position with respect to opposed limbs (25) of a metal bracket.

Patent GB-2217123-A (GB)
Title: Power control circuit with electronic protection
Inventor: ARENDT BODO
IPC: H05B39/04
Filed: 1989-03-30
Abstract: A power control circuit, such as a lamp dimmer, has a load connected in series with a bridge rectifier (GL) (Fig 1), across a supply, FET T1 connects across a diagonal of the bridge (FL) and turned on at each zero-crossing of the supply and turned off by a monostable M at an adjustable time in each supply half-cycle, and circuit elements R1, R2 C1, C2 which cause the FET T1 to turn off gradually with an S-shaped voltage-time characteristic (c) (Fig 3). Capacitor C2 acts as a Miller capacitor and its presence also causes FET T1 to turn on in the case of an excess voltage due to spikes. Current limiting is effected by means of transistors T2, T3 responsive to the voltage drop across resistors R4, R5 in series with FET T1, resistor R4 has a greater value than R5. Excess current results in a transistor T3 grounding the output of monostable M to give a gradual turn off of FET T1 and transistor T2 may subsequently turn on to ground the gate of FET T1 to achieve a faster turn off. A further transistor (T4), (Fig 4), may respond to switch an additional resistor R13 into the R-C circuit R1, R2, C1, C2 to give a reduced time constant whereby FET T1 is turned off faster and power dissipation is reduced. <IMAGE>

Title: Bending without interference
Inventor: WAKAHARA TAKASHI
IPC: B21D5/02
Filed: 1989-08-04
Abstract: A process setting device for a bending machine (1, Fig 4) comprises data input means 201, 203, calculation means 205, interference check means 205 and preparatory bending calculation means 207. Data concerning the original shape of the workpiece and the bent shape of the workpiece is input to the device. The device calculates the optimum bending process and checks, in a simulation of that process, that no interference between the workpiece and bending machine 1 will take place. If interference is found to take place the bending process is amended to include preparatory bending and the interference check is again carried out. If interference is still found to take place, an alternative bending process is calculated and checked. …<IMAGE>…

Title: Apparatus for handling packaged bottles, cans, or the like
Inventor: RICHARDSON EDWARD JAMES
IPC: B66F9/18
Filed: 1989-08-07
Abstract: The apparatus comprises a rectangular frame (20) disposed horizontally, which is fixed to the forks at (23), of a lift truck. Gates (29) depend downwards from the sides of the frame, and each gate carries a pad (32). When the gates are operated hydraulically the pads clamp a pallet-sized layer (43) of cardboard cases (36) therebetween. Other layers of cases resting on the clamped layer may be picked up along with the clamped layer. The layer is clamped on all four sides, and the pads are long enough that no bottle (38) can "escape" the clamping force. The apparatus allows a high clamp force to be used, without the danger of damaging the cases or bottles. <IMAGE>

Title: Oil recovery apparatus
Inventor: GORST IAN RONALD
IPC: E02B15/10
Filed: 1991-04-03
Abstract: An oil recovery apparatus comprises a buoyant body (10, 12, 14) with a conduit (32) mounted on the buoyant body and connectible to a suction pump.

Title: Non-contact measuring device
Inventor: FUKASE HIROSHI
IPC: G02B26/12
Filed: 1991-07-24
Abstract: A non-contact measuring device applies a scanning light beam, moving at a constant speed, to an object 120 to be measured and measures the shape of the object in accordance with the time for which the beam is obscured by the object. To provide the scanning beam, light generated from a source of light 102 is allowed to pass through a lens 142 to a polygonal mirror 104 rotating at a constant speed, and the light reflected by the polygonal mirror is allowed to enter a collimator lens 108. As it is necessary that the beam be focused at the position of the object to be measured, the distance between the light source and lens can be adjusted automatically according to the position of the object which is sensed by position sensor 156. <IMAGE>

IPC: G01S5/28
Filed: 1992-01-15
Abstract: Gas-operated apparatus 2 for making a noise underwater, comprises a body 4, a diaphragm 6 which extends over the body 4 to define a chamber 8 between the body 4 and the diaphragm 6, a gas inlet nozzle 10 which extends into the chamber 8 and which, in the non-operative condition, engages an inner surface 12 of the diaphragm 6, and a gas outlet means 14 for enabling gas in the chamber 8 to leave the chamber 8, the diaphragm 6 being made of an elastic material, and the apparatus 2 being such that in use gas under pressure passes through gas inlet nozzle 10 and causes the diaphragm 6 to expand and collapse over the region in contact with the gas inlet nozzle 10 thereby to create noise. The outer surface 16 of the diaphragm is preferably in contact with the water for optimum underwater transmission. Alternatively the diaphragm may be in contact with a liquid filled cavity (50, Fig 3) whose outer membrane (46) is in contact with water. The frequency and/or amplitude of noise is controllable by tightening the diaphragm via screw means 20 and/or by varying the gas pressure via a valve 28. The apparatus can be used as an alarm, for signalling or for range finding (Fig 6). <IMAGE>

Title: Reversing drum brake
Inventor: TURNER BRIAN
IPC: B60T7/20
Filed: 1993-02-12
Abstract: A reversing drum brake 1 comprises brake shoes 7, 8 and a collapsing mechanism 8 having pivotally mounted cranked members 20, 21 which engage respective brake shoe web members 2, 3. The members 20, 21 cooperate with one another by means of a pin 41 slidably engaging slot 40. In normal braking under forward motion (arrow 50), the pin 41 is urged against the bottom of slot 40 and web members 2, 3 are urged outwardly to effect braking. In braking under reverse motion (arrow 51), the pin 41 slides upwardly within slot 40 and members 20, 21 move inwardly, thereby allowing brake web members 2, 3 to move inwardly into a "collapsed" state. A self-adjusting device 4 (see Figs. 4 and 5) is also described which includes an adjuster screw 68 arranged to be screwed outwardly by an indexing finger 70 when the brake shoes have worn a predetermined amount. A cable 79 extends between indexing finger 70 and cranked member 20 and is arranged to disengage finger 70 from engagement with adjuster screw 68, when the brake is in a collapsed state. <IMAGE>
