Patent GB-2180181-A (GB)
Title: A power-operated tool, preferably a screw-tightening tool
Inventor: STEIN DIETER
IPC: B25B23/145
Filed: 1986-07-09
Abstract: A power-operated tool is fitted with a drive, whose driving shaft (17) can, by means of a toothed connecting coupling (36) whose disconnection depends on the reaction torque and a disconnecting, toothed coupling (20), be coupled with a driven shaft (45). When a predetermined reaction torque occurs, part (35) of coupling (36) is moved axially (Figures 3a and 4a) against bias of spring (37) to interrupt drive to the driven shaft (45), and to allow cam teeth (59) on part (25) of the coupling (20) to engage cam teeth on the portion of the driven shaft (45) which forms part of the coupling (36) so as to effect axial movement of the parts (25,19) of the coupling (20) against bias of springs (29,21). Further rotation of the driving shaft (17) causes the parts (25, 35) to be returned by springs (29, 37) to their initial positions, whilst part (19) is held in a disconnected position (Figure 6) by balls (54) until the power supply is terminated. <IMAGE>

Abstract: A gold circular earring 1 of hollow construction has two hollow arc-shaped portions 2, 3 joined in end to end relationship by hinge 4. A clasp 5 is diametrically opposed to the hinge 4. The hollow portions 2, 3 of the earring may be formed from seamed tubing drawn from sheet or strip stock, in which case the earring cross-section is 0.76-1 mm and the wall thickness of the hollow portions is 0.05-0.07 mm. In an alternative embodiment the tubular portions may be formed by electrodeposition of metal on a mandrel or model. Optionally, the earring is of gold and the caratage is controlled by a computer-controlled electroforming process which controls or varies current density or temperature of the plating solution. <IMAGE>

Title: Measuring electrostatic voltages
Inventor: LE SUEUR ERIC JOHN
IPC: G01R29/24
Filed: 1988-01-15
Abstract: A voltmeter for measuring indirectly the voltage of a charged photoreceptor of xerographic reproduction apparatus (not shown), operates by sensing the leakage current from a developer roll (2) which is at a known voltage relative to the photoreceptor. The net flow of leakage current to earth from the roll (2) via a leakage path (R1, R2) is detected (R2, A) and used in a feedback loop to apply an opposing voltage Vx to maintain the net leakage current constant, at which current the voltage of the photoreceptor can be calculated from the value of the opposing voltage and the known voltage between the photoreceptor and the developer roll. As shown, the feedback voltage is used to adjust the value of R1. <IMAGE>

Title: Fluorescent lamp dimmer
Inventor: RUNYAN WESLEY J
IPC: H05B41/36
Filed: 1988-10-13
Abstract: The brightness of a fluorescent lamp 302 can be controlled by adjusting the level of direct current provided by a current regulator 500 and by adjusting the ON pulse width of transistors 410, 420 in an inverter 400 which energises the lamp 302 and is supplied by the regulator 500. The regulator 500 comprises an inductor 514 and a switching transistor 506 controlled by a pulse width modulator 516 responsive to the comparison by transistors 541, 542 between the current sensed by a resistor 533 and a reference level 538. A further inverter 600 which supplies the lamp filaments 304, 306 has a pulse width controller 624. In order to conserve power and extend lamp life time the filament power may be varied by adjusting a control input 657 to controller 624 as the brightness command input signals 538 to regulator 500, and 490 to a pulse width controller 460 in inverter 400, are adjusted. The controllers 460 and 624 are operated in synchronism with modulator 516 at a clock rate determined by a capacitor 519 and a resistor 521. The command signals 538, 490, 657 may be adjusted by potentiometers 530, 464, 644 or generated from a master dimming signal. The arrangement may provide a dimmable backlight for an avionics display. <IMAGE>

Title: Low band colour converter for use in a video tape recorder
Inventor: YUN JONG-KYOUNG
IPC: H04N9/793
Filed: 1989-07-29
Abstract: In a VTR system in which colour modulated sub-carrier components of a video signal are frequency down-converted prior to recording, the components are first demodulated and then re-modulated at the lower frequency. The latter synthesis of the sub-carrier components enables their phase and frequency to be correctly coincident with those of horizontal synchronization signal in the VTR. An apparatus for achieving the conversion comprises a burst gate pulse generator 10, a down-converted frequency pulse synthesizer 20, a first (90 DEG ) delay circuit 30, a second (180 DEG ) delay circuit 31, a burst amplifier 11, a color signal demodulator 40, a first modulator 50, a second modulator for 51, and a mixer 60. The outputs of a first detector 70 and a second detector 71 control a color gain controller 80 and a color killer switching means 110. A low pass filter 100 receives the resulting signal. <IMAGE>

Title: Apparatus for use in the production of pastries
Inventor: RAHIM SALIM KAMRUDIN
IPC: A21C11/10
Filed: 1990-02-22
Abstract: A process to produce different kinds of pastries in which an extruder 24 forms regular discs of dough with a controlled thickness and diameter by extruding dough through a central opening 26 of a lower circular plate 21 which is heated and to which an upper plate 22 descends to an adjustable distance. For producing samoosas thin discs of dough are formed which are partly cooked at one side, stacked and further pressurized and heated. Each disc is cut into four quarters in which triangles are inscribed with their top on the middle of the circular side of each quarter. Filling material is charged in the middle of each triangle whereupon the four quarters are simultaneously folded into triangles, firstly along the sides and then along the bottom by using three hinged plates, one set for each quarter to be folded. For producing filled tortillas the partly cooked disc of dough is filled and rolled by a rolling machine. For producing chapatis or other flat pastries the partly cooked disc of dough is transferred to a station for finishing the cooking. <IMAGE>
