Patent GB-2061660-A (GB)
Title: Modifying the contrast of an image
IPC: H04N5/20
Filed: 1979-10-17
Abstract: A method of image contrast enhancement compares the brightness value of a pixel at a selected position with the individual brightness values of each other pixel in a surrounding local area and determines how many values are greater than, equal to or less than the selected pixel value. The result of this determination is used to produce an output brightness code for the selected pixel. The local area is rippled by at least one pixel at a time over the frame with the brightness value of the pixel at the selected position in the local area being recoded in accordance with the brightness of the pixels around it. The method may be used for infrared systems, medical X-rays and perhaps television.

Title: Process for Preparing Aromatic Polyphosphites
IPC: C08K5/527
Filed: 1980-01-29
Abstract: A process for preparing aromatic polyphosphites comprises reacting a pentaerythritol diphosphite compound having "leaving" groups with an excess of a bis-(hindered phenolic) compound. The resulting aromatic polyphosphite is free of phenol which fact enlarges its sphere of utility as a polymer stabiliser, especially for olefin polymers. The aromatic polyphosphites have the structure   <IMAGE> where the O atoms linking P to the benzene rings are in the 2- or 4-positions; each R is alkyl ortho to the OH or aryloxy group; R' and R'' are each H or alkyl; n is at least 1, preferably 1-10; and A is alkylidene or S. The pentaerythritol diphosphite compounds have the formula:   <IMAGE> in which X and Y are each halogen, amino, dialkylamino, anilino, morpholino or methylanilino.

Title: Alternating current motor with an electrical braking system
IPC: H02P3/24
Filed: 1980-08-15
Abstract: Capacitive braking of an a.c. motor M is effected by capacitance network (CX) whose reactance at motor supply frequency is substantially equal to twice the resistance of the motor winding(s). When the motor is stopped or the supply fails, contacts 1,5; 2,6; 3,7 open and contacts 9,13; 10,14; 11,15 close to connect the network (CX) to the motor windings. A d.c. braking source C4, as disclosed in G.B. patent 1551738, is connected to the motor windings after network (CX) has been disconnected, the source C4 completing the braking by DC injection and being switched into the motor circuit by delayed-operation switch means 36-40, 37-41, which is actuated by a contactor AC2 having a coil L2 energised by a.c. or, Figure 9 (not shown), a d.c. energised coil (DC). In a modification the braking system has an intermediate braking stage in which one of the capacitors in a star- connected network (CX) is short- circuited before completion of braking by the source C4. The embodiment of Figure 9 (not shown) has fail-safe operation to ensure that the motor is switched- off and braked in the event of (1) the welding-closed of the contacts of contactors AC1A, AC2A; (2) failure of bridge R or capacitor C4 or (3) failure of a capacitor (C5) controlling the coil (DC). <IMAGE>

Patent GB-2090195-A (GB)
Title: Data imprinters
IPC: B41L47/56
Filed: 1980-12-29
Abstract: A data recorder for imprinting credit card data onto paper sales forms for credit card transactions. The recorder includes a printing bed and a platen mounted for movement across the bed, whereby, when the card and form are in position on the bed, a roller on the platen moves over indicia on the card so transferring the data to the form. A lever is pivotally mounted and has two fingers projecting through apertures in the bed. When a card is correctly positioned the lever is pivoted so that the fingers are retracted whereby a form can be correctly positioned without disturbance upon movement of the platen. When the card is not correctly positioned, the lever is biassed so that the fingers stand proud of the bed whereby movement of the platen displaces the form.

Title: Load-responsive brake in brake trolley for track system
IPC: B61H9/02
Filed: 1982-06-04
Abstract: To take account of weight and track inclination variations, a brake trolley (1) has a longitudinally extending tie rod (11) which is movable by coupling forces applied thereto to cause working surfaces (16) of the tie rod (11) to act on projections (17) of brake cylinders (8a) to move the cylinders (8a) against the force of further springs (18) to supplement the brake applying force applied by springs (9) so that the braking force is related to the coupling forces applied to the tie rod (11). The trolley brakes are spring loaded brakes normally held off by pressure medium in chambers (8d) of piston/cylinder arrangements (8). Upon a determined speed being exceeded, the pressure of the pressure medium in the chambers (8a) is relieved to allow the stored force in the springs (9) to move levers (6) to apply the brakes. <IMAGE>

Patent GB-2127143-A (GB)
Title: Heat pipe
Inventor: RATTCLIFF GRAHAM
IPC: F28D15/04
Filed: 1983-02-24
Abstract: In order to prevent the vapour flow within a heat pipe from resisting the return of condensed, heat transfer liquid towards the evaporator section 23, the heat pipe is arranged so that it has separate paths for the vapour flow and liquid return, this being achieved by means of an open-ended tube 24 located coaxially within the heat pipe. The tube 24 is supported by means of a semi-porous plug 25 which causes the liquid to collect as at 26 and slowly drain into the evaporator section. Numerous modifications of the heat pipe, including one where the condenser section is at a greater angle to the horizontal than the evaporator section, are also disclosed. Where a wick for condensate return is provided, this may be sandwiched between the wall of the heat pipe and a coaxial inner tube to increase the area of plain wettable surface contact with the wick to improve the wicking performance. <IMAGE>
