A tyre repair patch comprises a main body 12 of cured rubber having a feathered edge 12a which extends beyond the feathered edge 16b of a connecting layer 16 of uncured rubber disposed on one face of the body 12. The main body 12 may be reinforced by cross-laid layers 13, 15 of rubberized nylon fabric which are separated by a neutralizing layer 14 of rubber. The central portion 16c of the connecting layer 16 may be thicker than the rest of the layer to provide a reservoir of uncured rubber to fill the cut or hole being repaired. The patch may be made by stacking on to a base layer 12 of uncured rubber, the fabric layer 13, a disc 14 of uncured rubber, and the fabric layer 15 which is disposed at right angles to the layer 13. The stack is then cured under heat and pressure to bond the layers together and to form the feather edge 12a. The connecting layer 16 of uncured rubber is preformed to the shape of the cured stack, but to smaller dimensions, and is united to the cured stack and protected by a layer 17 of foil. In use the projecting edge 12a forms a sealing flap.

Title: Improvements in and relating to data processors
Inventor: BARTON ROBERT STANLEY
IPC: G06F12/04
Filed: 1968-08-30
Abstract: 1,207,427. Data processors. BURROUGHS CORP. 30 Aug., 1968 [18 Sept., 1967], No. 41511/68. Heading G4A. In a data processor, an information item is handled in accordance with the value of a tag in the item which specifies if it has one or a plurality of words. The top two stages of a last-in-first-out stack each consist of two one-word registers, the rest of the stack being a series of consecutive wordlocations in a core memory the top-most of which is addressed by an S-register. Operands stored in the stack each consist of one or two words each word having a (3-bit) tag to indicate which (or in the case of 2-word operands only the more significant word may have the tag). An instruction address counter addresses the memory to obtain successive operators which operate on the top of the stack treating the operands as single or double word (precision) according to their tags. An ADD operator moves up the stack if necessary, until the top two stages are occupied with respective operands, then performs floating-point addition on the operands by a conventional algorithm which omits unnecessary steps in the case of one or two zero mantissas or equal exponents, the result being stored in the second stage. A parallel adder is provided, fed serially by word in the case of 2-word operands. A LOAD operator pushes down the stack until the top stage is empty (if either of the top two stages is initially empty, the memoryportion of the stack is not interfered with), then addresses the memory from a buffer register to obtain an operand to load into the top stage. A STORE operator moves up the stack if necessary, until the top stage is occupied (if the second stage is initially occupied, and thus can provide the operand for the top stage, or if the top stage is already occupied, the memoryportion of the stack is not interfered with). The top stage operand is then inserted into a memory address or addresses specified by the buffer register. In this, if the operand from the stack is of one word and the address it is bring transferred to is part of a two-word operand, the operand from the stack is converted to two-word form. Conversely a twoword stack operand is rounded-off to a oneword operand if the address it is being transferred to holds a one-word operand. In either case the tags are updated. Polish notation in which the operator follows the operands is mentioned.

Abstract: 1,173,120. Cigarette-making machines. BRITISH-AMERICAN TOBACCO CO. Ltd. 3 Sept., 1968, No. 41781/68. Heading A2C. In a means for exercising control, in a cigarette-making machine, in dependance upon short-term variations of air pressure detected by a pressure-responsive device at a point in the machine at which longer-term variation of pressure also occurs, wherein the detected varying pres-. sure is applied directly to one side of an air pressure unit and a compensating pressure applied to the other side, the effect of longer-term variation is compensated for by deriving the compensating pressure via a low-pass filter circuit from the same detected varying pressure. An air cell (not shown) is connected directly by a tube 6 to one side of a pneumatic capsule 2 and indirectly, via branch 14 leading to an integrating low-pass filter circuit comprising a capillary 13 and a reservoir 12, to the other side of the capsule 2. Dimensions of its components are given for a filter circuit having a time constant of 8 to 10 seconds and suitable for controlling the level of a tobacco-trimming knife of a cigarette-making machine in response to the resistance to air flow through the bed of tobacco on an air pervious collecting band of the machine as detected by an air cell.

Abstract: 1,121,370. Textile treating apparatus. ULTRASONA A.G. 6 Oct., 1965 [12 Oct., 1964], No. 42450/65. Heading D1L. A process for treating a continuous length of synthetic textile fabric to make it softer, less glossy and more voluminous, in which the fabric is subjected to treatment in a strongly attacking shrinking bath, while at the same time being subjected to ultrasonic waves and is immediately thereafter washed with a washing liquid that may contain a neutralizing agent for the shrinking liquid, is characterized in that the fabric is passed through a shrinking bath 1 in a path extending under a perforated conveyor belt 6 immersed in the bath, the speeds of supply and removal of the fabric to and from the bath and the speed of belt 6 being so mutually adjusted that practically no tensile stresses occur in the fabric, and the latter is caused to follow a path of movement extending substantially along the underside of the belt 6. The fabric is fed into the bath from roll 13 by feed rolls 11 and withdrawn over roll 17 and the speeds of rolls 11, depositing roll 12, belt 6 and roll 17 are adjusted accurately relative to one another, depending on the degree of shrinking of the fabric, by means of known continuously variable transmissions and/or separate variable speed motors. Shrinking liquor is fed to the bath 1 by perforated tube 8 extending across bath 1 and discharged through perforated tube 9, these tubes being connected by an external circulating system (Fig. 4, not shown) including pump 41, filter 42 dosage apparatus 43 and heater 44. In the bottom of vessel 1 a battery of ultrasonic oscillators 18 is arranged for emitting ultrasonic vibrations towards the fabric on the lower run of belt 6. After withdrawal from bath 1 the fabric is fed into a neutralising and washing vessel 19 (Fig. 2, not shown) where it is conveyed on the upper surface of belt 25. The vessel 19 is divided by partitions 20 into three collecting tanks 22, 23, 24 with overflow troughs 31-35 arranged above the upper run of conveyor 25. Trough 31 is supplied with cold water and the collected liquor in tank 22 is fed back to trough 32 and so on, the liquor being heated and having a neutralising agent added before it is fed to trough 35 (Fig. 5, not shown).

Abstract: 1303405 Hydraulic brake boosters GENERAL MOTORS CORP 16 Sept 1971 [29 Sept 1970] 43223/71 Heading F2F An hydraulic brake booster 24 having an input member 70 operable via a push rod 68 by a brake pedal 40, and an output push rod 58 operable on a master cylinder 30 incorporates an open centre valve operable to control hydraulic flow between an inlet chamber 80 and,an outlet chamber 82 of the booster 24, the chambers 80, 82 being formed on opposite sides of a power piston 78; the valve comprises a valve set 94 formed with a frusto-conical face 130 and cooperable with a valve element 132 on the input member 70 which element 132 is formed with a frusto conical face 134. The valve seat 94 has a skirt portion 102 defining a cylinder 107 and a reaction piston 110 has a land 114 received in the cylinder 104 and the reaction piston 110 also has a land 112 received in a cylinder section 106 defined by a stepped recess 92 in the piston 78: the lands 114, 112 allow of slight radial movement of the valve seat 94 if it, is off centre with the valve element 132. The booster 24 has an inlet 22 for a conduit 20 from an open-centre power steering gear 18 supplied with fluid by a pump 10; an outlet 26 from the booster 24 is connected to the sump of the pump 10. With the system at rest, the circuit is completed via the open centre valve and a passage 90 in the piston 78. To operate the booster 24 the input member 70 is moved leftwards and the valve faces 130, 134 contact to restrict flow between chambers 80, 82. Hydraulic pressure is built up in inlet chamber 80 and this pressure also acts in a reaction chamber 120 to urge the reaction piston 110 rightwardly although this initial reaction pressure is not transmitted to the member 70 since a spring 128 is supported between the piston 110 and the valve seat 94. The power piston 78 is moved leftwardly to operate the master cylinder 30 and as the pressure differential increases the reaction piston 110 is moved rightwardly until a snubber piston 126 contacts a snubber 146. A poised position is reached wherein the valve opening between faces 130, 134 is sufficient to maintain the required pressure differential; any excess pressure is relieved through a valve 152. On brake release a spring 140 moves the input member 70 leftwardly and the other components return to their at rest positions; the valve element 132 is cushioned by a bumper 138 and the reaction piston 110 by a snubber 116. If the hydraulic fluid is cold or foreign matter is present the power piston 78 moves to allow enlargement, the valve opening to provide relief. The valve face 134 may be constructed as two surfaces 147, 148 having angles "a", "b" of 31 and 29 degrees relative to the axis 151 with the face 130 having an angle "c" of 30 degrees: this produces a venturi effect which is said to reduce noise: the angles "a" and "b" may be the same and the angle "c" can be as much as 45 degrees. The booster 24 also has an electrohydraulic pump 36 actuated by a flow switch 38.
