Title: Device for forming electrical coils and transferring the coils for subsequent insertion into a slotted magnetic core
Inventor: WALKER ROBERT GERALD
IPC: H02K15/04
Filed: 1984-03-01
Abstract: A coil winding and inserting device has a coil form engageable with coil placer tooling and a rotatable flyer to generate coil turns while previously formed turns migrate downwards along the coil form and into fingers of the placer tooling. To enable coils to be pushed downwardly into spaces between selected pairs of fingers of the placer tooling without adjacent spaces between fingers being closed by overflexing of the fingers, a coil pusher has coil stripping portions with a laterally extending part 79 having diametrically opposed pairs of fins 81, 83, 85, 87. One fin of each pair enters a space to depress the coils, the other fin maintains the adjacent space to enable subsequent coil insertion. <IMAGE>
Patent GB-2158275-A (GB)
Title: DC-to-DC converter
Inventor: MERCER PETER ATHERTON
IPC: H02M3/335
Filed: 1984-04-28
Abstract: A DC-to-DC converter which provides a highly stabilized output (not shown), also provides a relatively high voltage output which need not be as highly stabilized as the other output. This is done by using a booster technique in which the voltage from one converter output is added to the DC input voltage VIN. In the present arrangement, stability of that output is improved and power consumption reduced by giving the smoothing choke an extra winding (L2) coupled to the smoothing winding (L1). This winding (L2) is returned via a diode (D1) to the zero voltage rail. With proper proportioning of the windings (L1 and L2) the above objects are attained. <IMAGE>

Patent GB-2147125-A (GB)
Title: Power supply
Inventor: PARKINSON KENNETH
IPC: H02M3/335
Filed: 1984-09-26
Abstract: A power supply comprises a pair of transformer primary windings (21, 22) connected in anti-parallel across a bridge rectifier (23). A number of secondary windings of the transformer (7) are connected to apply predetermined terminals (26 A-F). One output terminal (26C) is designated the regulated terminal and has its output monitored through a control loop (28-30) in order to vary the duty ratio of a transistor (25) connected in series with one of the primary windings (21). A further secondary winding (6) of the transformer (7) is connected to a rectifying and filtering circuit (8-11) to provide a voltage indicative of variations in power flow through the transformer. The voltage is compared with a reference voltage to alter the resistance of a current transformer (1) connected in series with the regulated output. Thus, a second control loop is provided to reduce the variation in the duty ratio of the transistor (25) to increase thereby the stability of all the output terminals. <IMAGE>

Title: Improvements in drive mechanisms
Inventor: EPTAS JOHN
IPC: F16D3/18
Filed: 1984-10-19
Abstract: A drive mechanism particularly suitable for a retractible azimuth thruster includes a vertical output shaft (10) keyed at (12) to hub (14) of a rotary coupling. The hub (14) is connected via spacer (16) to a sleeve (18) having splines (22) engaged by crowned teeth (36) of an inner hub (24) that rotates with the hub (14) whilst accommodating a limited degree of misalignment. The hub (24) is shrunk onto an upper portion (28) of a telescopic drive shaft which is suspended by a flexible tie wire (30) from the output shaft (10). Abnormal upward loads on the shaft (28) tending to buckle the wire (30) are resisted by distance piece (40). The weight of the shaft (28) is carried simply as a tensile load in the wire (30) without the need for bearing surfaces and misalignment is accommodated simply by bending of the wire (30). <IMAGE>

Title: Abrading tool
Inventor: JONES JOHN SYDNEY
IPC: B25D17/02
Filed: 1987-06-23
Abstract: An abrading tool has a matrix of identical elongate elements 60 arranged in parallel, each having an abrading head and, at the rear, a striking head. (An element may be U-shaped, thus providing two abrading heads.) A rotating striker 40 has projections 56 extending towards the striking heads. Rotation of the striker causes the projections to strike the striking heads, and thus to urge the elements forwardly.

Patent GB-2199460-A (GB)
Title: Image display
Inventor: RICHARDS NORMAN DENNIS
IPC: H04N7/26
Filed: 1987-11-18
Abstract: Pixel information representing an image for display is coded using data compression. The data compression consists in obtaining the pixel information as a first matrix of high resolution pixel values, subtracting from this first matrix a second matrix composed of lower resolution pixel values, produced by low pass filtering the first matrix, to produce a third matrix of difference values, sub-sampling the second matrix to produce a fourth matrix of less density lower resolution pixel values and coding the third and fourth matrices. Complementary decoding consists in restituting the second matrix by interpolation filtering the decoded fourth matrix, and combining the restituted second matrix with the decoded third matrix. Loss of accuracy in the decoding method is reduced by coding and then decoding the fourth matrix during the coding method before it is interpolated to full pixel density to form the restituted second matrix which is subtracted from the first matrix to produce the third matrix of difference values. In this way, any sub-sampling and interpolation errors in the restituted fourth matrix occur in both the coding method and the decoding method and therefore cancel out. Figure 3 illustrates the coding method including these coding and decoding steps.

Title: Process and device for making a fibre rod for the tobacco processing industry
Inventor: SIEMS WOLFGANG
IPC: A24C5/34
Filed: 1987-11-30
Abstract: A process and device for making a fibre rod are described, in particular for making filters or cigarettes or like smokable articles. A mobile fibre material rod (4) contains an additional material component (softener, water). By means of two measuring arrangements (37, 38) which record the influence of the rod components differently, the rod density is measured and differing first and second rod density signals are produced. In an evaluation arrangement (42) the first and second rod density signals are processed to form a difference signal, which represents a measure of the proportion of additional component in the rod, and is used to control an arrangement (33) which influences the proportion of additional component. The measuring arrangement (37) comprises an X-or beta-ray transmission sensor, and the arrangement (38) comprises an infra-red, light or ultra-violet transmission sensor. The arrangement (37) may be replaced by weighing scales (31a). In the case of cigarette rods, the difference signal may be used to control trimming disks which remove surplus material. <IMAGE>
