Title: Loop-gain control system in a spindle servo loop
Inventor: WATARI HARUO
IPC: G11B19/28
Filed: 1989-10-10
Abstract: A method of controlling a servo control loop for a disc player initially sets an offset value, which is used throughout search and playback to control the gain of an equalizer (15) in the servo loop. The offset value is determined by first moving a pickup head (3) to a radially central position of the disc (1) and reading the time code address data recorded at that position. The read address is compared with a calculated, expected address to determine if the two are within a given distance. If they are, the offset is set as a predetermined value, e.g., zero. If they are not within the given distance, the offset is determined in one of two ways. Either the difference is used as the offset, or the pickup head (3) is moved to the innermost circumference of the data portion of the disc (1) and the address data read therefrom is used as the offset. During search and playback, the offset is subtracted from the continuously read address data, and the difference controls the gain of the equalizer (15). …<IMAGE>…

Title: Hairdressing cape
Inventor: GRAHAM DAVID PAUL
IPC: A45D44/08
Filed: 1991-04-17
Abstract: A hairdressing cape comprises a circular sheet 1 of plastics material which has been radially cut at positions 2 and 3 so as to provide an opening and overlap when the sheet is placed around the shoulders of a client. A non-woven fabric collar 4 is provided which, when in use, makes close contact with the client's neck because it is elasticated at edge 6. Short hair clipping become entangled with the fabric of the collar and also are electrostatically attracted to the plastics sheet 1. in a second embodiment (Fig. 2) the non-woven fabric collar 4 is extended so that it is almost as large in diameter as the plastic sheet 1 and acts as an improved collector because within its fibres is induced an electrostatic charge generated by friction when the two sheets rub together in the act of placing the cape around the shoulders of the client. In both embodiments the cape is held under tension, in use, by adhesive tabs 5. <IMAGE>
Patent GB-2247815-A (GB)
Title: Dielectric heating
Inventor: OVADIA AKA DAVID GILHESPY DAVI
IPC: A21D8/06
Filed: 1991-07-10
Abstract: Products, especially gas-permeable, water-containing products such as bread dough are rapidly heated under non atmospheric pressure. Baking of dough involves placing the dough within an enclosed oven or zone (1) and subjecting the dough to dielectric (e.g. radio-frequency or microwave) heating using appropriate generators (8, 8a). Radiant heat from an appropriate source (9) and hot oven gases are simultaneously applied for crust formation. During at least a portion of the baking cycle, the gas pressure within the zone (1) is selectively elevated by steam addition (10) in response to the rise in gas pressure within the dough resulting from vaporisation of water therein. In this way, the pressure differential between the dough interior and the ambient environment is minimised, and the dough may be rapidly baked without fear of significant dough disruption. Cooling is effected by gradually reducing the zone pressure, through use of a vacuum pump (12). If desired, vacuum cooling can occur simultaneously with continued radiant heating crust formation. The process gives completely baked and cooled bread in a matter of minutes. Fruit and vegetables may be dried under vacuum and medical instruments sterilised in steam at above atmospheric pressure, using radio-frequency or microwave heating. <IMAGE>

Abstract: An adjustable shelving bracket comprises a first component 1 for attachment to a wail or other vertical surface and a second component 3 which supports a shelf panel (not shown). The components 1 and 3 are pivotally interconnected via a shaft 2 attached to component 1 which rotates within a slot 14 in component 3. A further shaft extends through component 3 and forms projections 12 which engage in a selected pair of three pairs of slots 8, 9 and 18 in an enlarged upper portion 6 of component 1. This further shaft is connected to shaft 2 by a spring 13 which acts to draw the shafts together, and thus ensures that the projections 12 remain in the slots. Each pair of slots 8, 9 or 10 defines a particular position for the component 3 relative to the component 1, and enables the angle of the shelf to be adjusted between selected positions. <IMAGE>

Title: Electric connectors formed of aluminium spray coated with copper
Inventor: DAVIDSON GORDON JAMES
IPC: C23C4/08
Filed: 1992-02-03
Abstract: A bimetallic electric connector for copper to aluminium joints is made by first forming a bulk component of aluminium (typically a stock aluminium connector) and then coating an appropriate part of its surface with copper or a conductive copper alloy (such as brass) by a thermal spray coating technique, such as plasma spraying or gas-wire metallising. The coating may be porous, in which case the use of a pore sealant e.g. an air-drying glyceride resin is recommended and this may also form a corrosion-resistant layer over the edge of the copper (or copper alloy) coating. Suitable coating and sealing techniques are commercially available. The technique is less expensive than conventional friction welding, and offers additional design flexibility. The connector illustrated in Fig. 1 comprises an aluminium tube 1 flattened at one end to form a palm 2 through which are formed holes 3, 3, the entire surface area to the left of the line 4 being coated with copper. <IMAGE>
