Abstract: 1418651 Surgical stitching instruments A M VIOLANTE 30 Oct 1972 [14 Feb 1972 26 Sept 1972] 49896/72 Heading A5R [Also in Division Dl] A surgical stitching instrument comprises a generally tubular body 12, Fig. 1, means for mounting a spool 16 on one end 14 and means for mounting a hollow needle 20 on the other end 18, a recess 28 adjacent the end 18 and openings 24 and 26 for the passage of a thread 32 from the spool 16 into the lumen of the needle 20 via the recess 28. The needle 20 terminates in the recess 28 and the thread 32 of suture material may be payed out through the needle 20 by the action of a thumb in the recess 28. A nipple 44 may be provided at the side of the body 12 to hold the needle transversely of the body 12. The needle may take various forms (Figs 4, 5, 8a, 8b and 8c not shown). In another embodiment, a spool 152, Fig. 12, is retained in a large bore 154 and feeds a thread 160 through a bore 162 and the lumen of a hollow needle 164. A recess 166 is provided for use as described above. In addition the recess 166 is adapted to receive a flexible walled container 108 containing medicament and having a sealed tip 110. When the container 108 is inserted in the recess the tip 110 is pierced by the sharpened end of the needle 164 and the medicament expelled into it. The container 108 may also be used with the embodiment described above with reference to Fig. 1. A needle protecting sheath (120), Fig. 13, (not shown) is adapted to fit over the tip (174) of the instrument and carry a removable scalpel (176). A feed tube attached to the needle 164 may be used to introduce liquids into a body.

Filed: 1971-10-28
Abstract: 1412413 Fuel injectors C A V Ltd 19 Oct 1972 [28 Oct 1971] 50066/71 Heading F1B A liquid fuel injection nozzle comprises a fluidpressure operable resiliently loaded stepped valve member 15 opened by fuel pressure acting on a surface defined on its wider portion to allow fuel flow from inlet 18 to outlet 16, a piston 24 of smaller cross-sectional area than said surface operably associated with the valve member and located in a cylinder 22 which can be supplied with fuel at substantially the same pressure as that supplied to inlet 18 via a conduit 23 fitted with a non-return valve. This augments the force exerted by the resilient means 19 to increase the closing force exerted on the valve member. The piston and valve member are connected by push rod 21. In the system shown in Fig. 1, fuel is supplied by a pump 9 to nozzles 10, 11, 12 in turn, the peak pressure reached to cause opening of the valve member of nozzle 10 being supplied also to the cylinder 22 of nozzle 11 so that a higher peak pressure is needed to open the valve member of nozzle 11. The system thus starts from rest with a low nozzle opening pressure, which increases as the engine speed rises. In Fig. 2 (not shown), the conduit leading to the cylinder holding the piston 24 is branched from inlet 18 within the nozzle body.

Abstract: 1,248,745. Disc brakes; fluid pressure actuator. BENDIX CORP. 8 Nov., 1968 [14 Nov., 1967], No. 53070/68. Headings F2E and F2F. A disc brake comprises a rotatable disc 64, a fixed support 10 having a pair of circumferentially spaced arms 20, 22 and 24, 26, and a floating caliper with spaced end portions 30, 32 held against the arms by resilient means 34, 36, 38, 40 allowing limited rocking motion, the caliper including a housing 28 containing an actuating piston and straddling the disc to embrace friction elements 42, 44 which can be actuated by rocking the housing by means of an arm 54 extending from the housing. The caliper includes sleeves 108, 110 slidably mounted on pins extending through projections 126, 128 of the housing. When the pads are applied by actuating the piston, the caliper slides in the sleeves 108, 110 and the springs 34 ... 40 prevent rattle and allow limited sleeve movement to prevent "knock back" of the piston. The pads can also be applied when arm 54 is actuated by a parking brake cable 62. In this case the springs allow rocking movement of the caliper including the sleeves and return them to the off position when the lever is released. One piston is pivotally mounted on the housing and the other can pivot so that they remain parallel with the disc which is hollow and air cooled. The piston includes adjusting means comprising an adapter 175 slidably mounted in a hole in the piston 46 with an extension 182 carrying a spring ring 184 which frictionally engages a sleeve 180 threaded on a nut 176. The sleeve 180 cannot state but can move axially through the distance 180. A torsional spring 196 is mounted between the adapter and the nut to rotate the nut and thereby maintain the adapter against the piston as it moves forward due to brake wear. The inside of sleeve 180 is connected to the surrounding space by passages 177, 179 to allow bleeding through screw fitting 194. (For Figures see next page.)
