Patent GB-2220547-A (GB)
Title: Electric immersion heaters
Inventor: TAYLOR JOHN CRAWSHAW
IPC: A47J27/21
Filed: 1989-07-06
Abstract: An electric immersion heater having an element head for use with a thermally sensitive control (1), said element head being thinned in the region of or over an area (12) surrounding or including the region of the hot return portion (5). Under boil dry or switch on dry conditions this thinning will impede the radial diffusion of heat in the head and reduce the conduction of heat to the periphery of the head to give further protection to the peripheral seals. Impeding the radial diffusion of heat also concentrates the heat near the hot return position and enhances and directs heat conduction to the primary protector switch 11, thus reducing the response time of the primary protector and hence overshoot temperatures, and allowing secondary protection switch 18 to be set to operate at a lower temperature whilst minimising nuisance tripping. <IMAGE>

Patent GB-2233212-A (GB)
Title: Article of attire
Inventor: BOOTH PATSY
IPC: A41D1/18
Filed: 1990-05-04
Abstract: An article of attire which is suitable for quick changes comprises a garment with an attached neck decoration 21 to 24. The garment may comprise only part of a conventional garment, e.g. a shirt 11, the absence of the remainder of the garment being camouflaged by a covering garment (a jacket, Fig. 3).

Title: Branched supply network earth continuity testing by DC injection into each branch
Inventor: WRIGHT STEVEN LAWRENCE
IPC: H02H11/00
Filed: 1991-01-29
Abstract: The installation comprises a branched power socket chain connected (at A) to a power source through a control unit B, with a pilot conductor E linking each branch end C3-C6 to the control unit B. A network with (n-1) branching points will have n branch ends, and in the present case n will be between 1 and, Bay, 5. The control unit B includes a current source for driving a controlled DC current through the pilot conductor E into the earth conductor through terminating impedances F1-F4 at each branch end C3-C8, thereby establishing a pilot potential on the pilot conductor E. The control unit B has a model circuit adjustable in steps according to the value of n and generating a reference potential that will normally equal the nominal pilot potential. The control unit B compares the reference potential to the pilot potential and disconnects the supply when the difference exceeds a predetermined amount in either direction. The terminating impedances are preferably equal resistors. The installation may be used with office furniture. <IMAGE>

Patent GB-2368188-A (GB)
Title: Infrared detector
Inventor: KNOWLES PETER
IPC: H01L31/024
Filed: 1991-05-10
Abstract: An infrared detector for operation at a cryogenic temperature has a photoconductive element (10) supported by a mounting substrate (26) which is formed as a sandwich comprising at least two superimposed thin layers (27, 28) of a material of high thermal diffusivity separated by a layer (29) of bonding cement which is sufficiently thin to leave the thermal properties of the substrate (27) substantially unaffected. The substrate (27) is very rapidly cooled by suitable cooling means (20), such as an open cycle Joule-Thompson mini-cooler (17), but its sandwich construction (27, 28, 29) reduces the incidence of electrical noise induced in the photoconductive element (10) thereby enabling increased performance. The element (10) may be epitaxially grown on a gallium arsenide layer (27).

Abstract: A method and circuit process image data of a dot matrix printer in a page printer. Dot matrix image data is received 501 and how many dots in the page printer correspond to one dot of the image data is calculated 503. A bit number representative of the location in vertical pins of a dot matrix printer head is initialized to a most significant pin numbed 505. A bit corresponding to the bit number of the input data is checked 509 to form a line segment 511 and the line segment is converted into raster data 513. Further, the raster data is inserted in an image buffer 513 and data of the image buffer is stored in a symbolic buffer 515. A check is made to see if the bit number of the input data is a least significant pin number 517. If the bit number of the input data is not the least significant pin number, a next pin number is redesignated. <IMAGE>
