Abstract: 1,155,032. Potassium salts of ether-acids. IMPERIAL CHEMICAL INDUSTRIES Ltd. 17 Nov., 1966 [24 Nov., 1965], No. 49943/65. Heading C2C. A potassium salt of an ether of a p-hydroxy benzoic acid is produced by heating a potassium salt of an ester of an alcohol having at least one hydroxy group and p-hydroxy benzoic acid or of an alcohol having at least one hydroxy group and an alkyl or alkoxy substituted phydroxy benzoic acid. The said potassium salt of the ester may be produced in situ by using the free ester and KOH, K 2 CO 3  or KHCO 3 . The ester starting material may be the ester of a monohydric alcohol or the mono- or di-ester of a dihydric alcohol. The products of the process of the invention may be converted to the free acids by acidification.

Filed: 1974-11-19
Abstract: 1463735 Exposing and developing heat sensitive materials XEROX CORP 19 Nov 1974 [27 Dec 1973] 49975/74 Headings G2A G2C and G2X A copy of an original 10 is produced by forming a heat image on a heat-sensitive member 12 by exposing both to a heat source 26 by passing them past the source, separating them, and passing the member 12 to a developing station 36, 38. The  image, which is tacky, is developed by dusting with pigmented toner particles. The member 12 is then returned past the source 26 which either transfixes the image to a copy sheet 14 or fuses it on the member 12, the same edge of the member 12 being the leading edge throughout the process. The original 10 enters the apparatus at 4 with the member 12, and leaves at 6, whilst the sheet 14, which enters at 8, leaves with the member 12 at 4. The paths of the three parts 10, 12, 14, 15 evident from the Figure, the direction of rotation of rolls 16, 26 being reversed after passage of 10, 12 and before arrival of 12, 14, see Fig. 2 (not shown). The heatsensitive sheet 12 comprises a support e.g. of poly-  ester, cellulose acetate or triacetate film, coated with a delayed tack adhesive which on being activated to a tacky condition by heat and subsequently cooled to room temperature remains tacky for a period varying from at least 30 seconds to several days depending on the composition involved. The tack coating may contain particles of a resin e.g. indene or esterified resin and particles of a plasticizer e.g. diphenyl phthalate or N-cyclohexyl paratoluene sulphonamide.dispersed in a binder such as styrene-butadiene copolymer.

Abstract: 1403334 Marine vessel water intake I HIKITA 2 Nov 1973 [15 Dec 1972 17 May 1973] 51048/73 Heading B7S A cooling water intake for the engine cooling system of a marine vessel which uses sea water as the engine coolant comprises a block 3 having a throughbore, the block being secured in a hole 2 through the hull 1 of the vessel, an intake pipe 4 which is slidably inserted in the block 3 and is held therein by a pipe holding means 6, a strainer 5 carried at the outer end of the pipe 4 and a closing means 7 in the form of a shut-off plate 71 pivoted on a shaft 73a, which can be actuated to close the throughbore in the block 3 when the outer end of the pipe has been withdrawn sufficiently far inboard of the vessel. In this arrangement the pipe 4 which is connected by piping 40 to the engine may be withdrawn into the vessel for cleaning of the strainer 5. In its normal operating position the outer end of the pipe 4 projects beyond the block 3 and is held by the holding means 6 which comprises a ring 61b on the block 3 to which is secured by screws 61c a frame 61 carrying at its inboard end a coupling ring 61a in which is screwed a coupling pipe 62 mounted rotatably on but fixed axially with respect to the pipe 4. By rotating the handle 62b of the pipe 62 the pipe 4 may be withdrawn from the position shown and the shut-off plate 71 may then be pivoted by means of a handle 73b on its shaft 73a to close the throughbore in the block 3, a spring 73d round the shaft 73a and a packing 8c provided on the internal surface of a cover 721 preventing the entry of sea-water when the plate 71 is in this position. In a simplified embodiment the outboard end of the pipe 4 does not project beyond the block 3 so that the shutoff plate 71 may be actuated when desired, the pipe 4 in this case being retained in its working position by a screw-threaded collar.

Abstract: 1,191,271. Trimming moulded articles. DUNLOP CO. Ltd. 5 Dec., 1966 [15 Dec., 1965], No. 53345/65. Heading B5A. Table-tennis balls are removed from surrounding sheet material by pressing the sheet against a plurality of oversized circular blades through which the severed balls pass. The resultant equatorial flash on each ball is removed by rotating it relative to a fixed cutting tool. As shown in the figure, the sheet containing the balls is initially carried by spring biased members 719 above circular hollow blades 718. Located below the blades are a horizontally reciprocable tailstock 724, the underside of which carries a plurality of freely rotatable suction pads 727 adapted to engage the upper surfaces of the balls, and a vertically reciprocable headstock 730 carrying rotatable suction pads 732 adapted to engage the lower surfaces of the balls. Located to the sides of the heads-bock are cutting blades 730, each of which is mounted upon a horizontal slide 744 itself mounted upon a vertical slide and is movable through an arc about the equatorial region of each ball by means of a cam follower 750 which rides over cam surface 752. In operation the sheet is pressed downwards against the blades, to sever the balls from the rest of the sheet, by means of pressure pads carried by a reciprocable upper member (see Fig. 1A, not shown). During this time the tailstock is positioned to the right as viewed to the figure over a discharge station and the headstock is in its uppermost position so that pads 732 project into the blades and receive the cut balls. The pads 732 are then lowered, the tailstock moved to the left to a position in which pads 727 overlie the balls, and the pads 732 re-raised to clamp the balls between them and pads 727. The pads 732 are then rotated and the blades 730 forwarded into cutting engagement with the equatorial regions of the balls thus trimming them. The pads 732 are finally lowered, the balls being returned by the upper pads, and the tailstock moved to the right to the position over a discharge station into which the balls are dropped.

Abstract: 1,165,429. Pedal mechanisms. FORD MOTOR CO. Ltd. 24 Nov., 1967 [2 Dec., 1966], No. 53514/67. Heading B7E. [Also in Division F2] An actuating and tension regulating mechanism for a cable 42 operating a clutch or brake, comprises a cable arm 32 attached to the cable 42, a pedal arm 10 frictionally contacting the cable arm 32, and a coupling coil spring 28 which locks the cable arm 32 to the pedal arm 10 when the pedal arm 10 is moved away from the rest position and unlocks the arms when the pedal arm 10 moves back to its rest position. The coil spring 28 is anchored to a member 26 which is secured to pedal arm 10 by a bracket 22 and the spring surrounds a shaft 12 splined to the cable arm 32. One end of the spring 28 terminates in a tang 30 which engages a stop member 46 in the rest position of the pedal arm 10. Friction material 34 may or may not be located between the arms 10 and 32. Adjustment of the frictional force may be effected by a nut 38 on a screwed portion 14 of shaft 12 and engaging a Belleville washer 40 acting on a pressure plate 36. On actuation of pedal arm 10, coil spring 28 tightens around shaft 12 to transmit movement to cable arm 32. When pedal arm 10 is released it returns to its rest position, under the influence of a spring 50, and the grip of spring 28 on shaft 12 is loosened. The cable arm 32 returns to a position in which the torque acting on it due to the cable 42 is balanced by the frictional torque between the arms 10 and 32 whereby a minimum tension in the cable is maintained.
