Patent GB-2217854-A (GB)
Title: Testing logarithmic amplifiers
Inventor: CHADWICK PETER EDWARD
IPC: G01R27/28
Filed: 1988-04-26
Abstract: The method includes measuring the transfer characteristic accuracy of a logarithmic amplifier using a modulated signal and an attenuator of lower accuracy than that of the amplifier. The method may utilise two modulated signals and the attenuator may be a PIN diode. The degree of departure of the detected signal solid line from a constant level indicates the degree of departure of the amplifier from a logarithmic response. <IMAGE>

Title: Method and apparatus for the quenching and transformation of steel shot
Inventor: MOORE JOHN
IPC: C21D1/62
Filed: 1988-07-14
Abstract: Austenitic steel shot at above 720 DEG C is fed into a fluidised bed of steel shot in a first container (20). Fluidising coolant air is passed through the bed to quench the steel shot to a temperature in the range of 250 DEG C to 450 DEG C.

Title: Multiple source physical vapour deposition.
Inventor: BICKERDIKE ROBERT LEWIS
IPC: C22C1/00
Filed: 1989-04-21
Abstract: An improved method and apparatus for the production of alloys by a process of evaporating and condensing constituent vapours utilises at least two evaporation sources communicating with a conduit which has a single discharge outlet facing a collector. Means are provided to heat the walls of the conduit to a temperature at least as high as the hottest source to suppress condensation and to promote mixing of the respective vapour streams by scattering from the hot walls. In a preferred arrangement sources (1, 2) are mounted vertically, one above the other, in a flue (4) heated by radiant heater (7). The flue radiates heat onto second source (2). The more volatile constituent is evaporated from lower source (1) by heater (6) and its vapour flows upwards past second source (2) into mixing zone (8). Here it mixes with vapour from source (2) and the mixture passes from the flue onto collector (5).

Title: Overwriting display memory without clearing speeds computer animation
Inventor: JOY WILLIAM
IPC: G09G5/14
Filed: 1989-05-18
Abstract: To reduce the time interval between frames in a computer animation system the display memory is not cleared between frames. The display system has a first full screen bitmapped display memory 13, 14 and a second memory 17, 18. The second memory 17, 18 holds, for each pixel in 13, 14, the number of the frame that that particular pixel appears in. Thus only those pixels relating to frame O are read out during frame O, etc., and rather than clearing the display memory data can be overwritten because the frame numbers in the second memory 17, 18 will prevent the production of spacious images. A similar system (Fig 2) is used in a windowing system. <IMAGE>

Title: Liquid applicator
Inventor: HAMMOND JOHN MICHAEL
IPC: A47L13/17
Filed: 1990-03-29
Abstract: A liquid applicator for, e.g. liquid shoe polish, has a capsule (18) containing the liquid disposed within, and surrounded entirely by, an enclosure (12, 14). The enclosure is formed of two blocks (12, 14) of foamed plastics glued together along an interface. One block (12) of the enclosure is liquid impervious and relatively rigid, but the other (14) is flexible and porous. The capsule is formed of a thermoformed sheet plastics member (20) having a peripheral flange (30) to which a diaphragm closure is attached. Two reentrant spikes (32) which are integrally formed in the sheet plastics member are capable of puncturing the diaphragm (22) to release the liquid product onto the porous block (14) when the applicator is compressed. The porous material can then be used to brush the liquid onto a surface to be treated.

Title: Apparatus for securing a load
Inventor: HELANDER DICK
IPC: B60P7/08
Filed: 1991-09-06
Abstract: An apparatus for using a lashing strap to secure a load to a load carrier, particularly the bed of a truck, includes a profiled rail 9 and a tensioning winch 1 which can be longitudinally displaced thereon into any desired lashing position. The tensioning winch 1 includes a profiled slot 21 whose cross-sectional configuration conforms to that of the upper portion of the profiled rail 9 so as to enclose the upper portion and lock the tensioning winch to it. The profiled rail 9 and the profiled slot 21 together form a closed guide. The cross-sectional configuration of the upper portion of the profiled rail 9 is adapted exactly to the profiled configuration of the profiled slot 21. The cross-sectional configurations of the upper portion of the profiled rail 9 and of the profiled slot 21 are asymmetrical, which permits the tensioning winch 1 to be pushed onto the profiled rail 9 only if it is correctly oriented with respect to the rail. <IMAGE>

Title: A process for treating cereal grain prior to milling
Inventor: FORDER DENNIS EDWARD
IPC: B02B3/00
Filed: 1993-07-09
Abstract: A process for treating cereal grain prior to milling in which the stock is initially wetted to soften and loosen an outer portion of the bran coat. It then passes through a debranning stage in which the first portion of the bran coat is removed by a mechanical treatment after which the grains are cleaned and then tempered by the addition of water to penetrate into the grains. After tempering further wetting is effected to soften and loosen the remaining bran coat which is subsequently removed in a final debranning stage, again by mechanical treatment, thus rendering the stock easy to handle for transfer to a milling machine without the risk of agglomeration of the grains which might otherwise occur if the entire bran coat were removed prior to tempering. At the separate debranning stages the bran is collected for further treatment and use.

Title: Reinforced base plate for cooking vessel
Inventor: KIM MYUNG-SUK
IPC: B21D51/22
Filed: 1994-06-28
Abstract: A cooking vessel is disclosed which comprises a stainless steel body (10) and a plate attached to the base of the body (20). This plate can be composed of copper, copper alloy, aluminium or aluminium alloy. The plate is reinforced by introducing material in the form of a mesh or net into the plate (30, 31). The reinforcing material has a different heat conductivity to the plate and may comprise ferrous or non-ferrous metals e.g. steel or copper. The reinforcing material may be made of magnetized material thus allowing the cooking vessel to be used with induction heat. The net or mesh material may form different patterns e.g. diamond (32), spiral. The net or mesh is inserted into the plate by the use of heat and a friction press which inserts the reinforcing means until it lies flush with the surface of the plate. <IMAGE>

Title: Beds and backrests therefor
Inventor: MINSHULL ROBERT JOHN
IPC: A61G7/07
Filed: 1994-07-06
Abstract: A bed has a backrest framework (61) which includes a back support member (63) comprising a generally rectangular frame (64) enclosing a mesh panel (74) or cross bars. A linkage (68, 71, 72, 73) is adjustable for retaining the back support member (63) at the head of the bed in a generally upright position, and at various locations axially spaced from the head of the bed. The back support member (63) is pivotally movable (via (69), (75)) with respect to the linkage which is in turn pivotally mounted to the head of the bed (80, 81, 82, 83). This permits the back support member (63) to be secured in various inclined positions. This arrangement is advantageous in that, if an occupant of a bed wishes to adopt a sitting position, the back support member (63) can be moved out towards the occupant and thus it is not necessary to lift and drag the occupant to the head of the bed. The backrest may also have armrests (fig. 3, not shown). <IMAGE>
