IPC: B23F19/12
Filed: 1983-05-06
Abstract: Method and apparatus for finishing edge or crest portions of the teeth of a workpiece, particularly teeth (13) of a bevel or other gear wheel (10) uses a resilient abrasive or polishing element, typically a rotatably driven abrasive faced disc (12) which is repeatedly deformed by passage of said edge or crest portions during relative feeding movement e.g. the rotation of the gear wheel about its axis. The finishing element may also be traversed longitudinally of the teeth in a rectilinear path. A rotating mop or brush charged with abrasive or polishing compound, or a non-rotating flexible abrasive flap or block may be employed as a finishing element, and screwthreaded components or toothed cutting tools may be treated. <IMAGE>

Title: Dyeing shrinkable textile fabrics
Inventor: WESSELY DAVID ALAN
IPC: D06C27/00
Filed: 1983-05-23
Abstract: Polyester knit fabrics are dyed in a process which involves first subjecting the fabric to a preparatory heat treatment under conditions in which the fabric is allowed complete freedom to relax and shrink, after which the fabric is wound onto a dye beam and beam-dyed. The preparatory heat treatment may be performed in a loop steamer at a temperature of 120 DEG -180 DEG C. Following dyeing the fabric may be subjected to finishing operations, such as napping, and then to a tentering operation in which the fabric is stretched widthwise to restore a predetermined width, while being heated to a temperature greater than that used in the preparatory heat treatment.   <IMAGE>

Title: Power amplifier for driving a gas discharge lamp
Inventor: STEVENS CARLILE RICHMOND
IPC: H05B41/392
Filed: 1983-06-22
Abstract: A source of regulated DC voltage (1) supplies a power amplifier section (3). The power amplifier section (3) operates in response to the output of an oscillator and amplifier drive (4) to drive a load (19) in the form of a gas discharge lamp. The power drawn by the power amplifier section (3) is monitored by a current sensor (7).

Patent GB-2148633-A (GB)
Title: Improvements in or relating to electrical circuits
Inventor: OWERS LEONARD CHARLES
IPC: H05B3/34
Filed: 1984-09-25
Abstract: An electric blanket comprises an electrical heating coil element R3, and a resistor/capacitor network (R1, R2/C1, C2) controls potentials on the trigger (G) of a thyristor (D). If heating coil R3 or its connections should suffer a break, the thyristor switch D will go into its non- conducting mode to open the circuit. If the broken ends of the heating coil R3 or its connections should touch and remake the break, the thyristor switch D will stay non-conducting, because C1 is still full charged. Hence no arcing can occur at the break. The application of supply power to the heating coil R3 cannot be re-established until isolating switch S is first opened and then re-closed. On the supply being reconnected, the pulse of current recharging capacitor C1 causes a potential to be established across resistor R1, thus charging capacitor C2 to a voltage sufficient to gate switch D to its conducting state once again. <IMAGE>

Title: Direction finding radar receiver with automatic calibration
Inventor: WONG ANDREW CHI-CHUNG
IPC: G01S3/04
Filed: 1984-12-12
Abstract: In a method for automatic calibration of an elevation finding phased array radar receiver wherein received signals are converted into digital information 16 for processing in a programmable data processor 18, the radar is set to illuminate 11, 12, 13 a predetermined patch in the far-field defined by the transmitted radar beamwidth and range cell size. The backscatter energy from the patch towards the receiver array 14a-14n must exceed a minimum level above the noise floor, so that the backscatter energy appears as a uniform field within one range cell coming nominally via a direct path and thus simulates a far- field point source, The processor 18 is programmed to calculate the expected phase gradient at the receiver array elements 14a-14n of radiation from the patch; comparison of this with the measured values allows calibration of the system. <IMAGE>

Title: Inverter or converter circuit arrangement
Inventor: JANSSON LEONARD ERIC
IPC: H02M7/5383
Filed: 1985-03-08
Abstract: In an inverter or converter circuit arrangement of the "constant current" type the handling of an input voltage applied between a pair of input terminals (34, 35) is distributed between at least two pairs of switching transistors (2, 3 and 4, 5 respectively) in a predictable way by including at least two circuit sections (12 and 18 respectively) in a current path (33) between the input terminals, which current path includes the usual choke (36). The two terminals (15, 13 and 20, 22) of each section are constituted by a centre tap (16, 21) on a respective winding (11, 17) of a transformer (1) and the junction point of the relevant pair of switching transistors (2, 3 and 4, 5). Because the switching transistors are bidirectional the arrangement is self-adjusting as regards the distribution of the input voltage between the two sections. A d.c. output voltage may be derived from the junction point (37) between the two sections and/or an a.c. output voltage may be obtained from a further winding (39) on the transformer. <IMAGE>
