Title: Improvements in hypodermic syringes
IPC: A61M5/315
Filed: 1959-10-27
Abstract: 871,854. Hypodermic syringes. FAURE, J. M. Oct. 27, 1959 [Oct. 27, 1958], No. 36392/59. Class 81 (2). A syringe ampoule 1 has two pistons 5, 6 joined by a rod 7 so as to provide a chamber 10 in which powdered medicament is stored and a second' chamber 9 which contains a liquid medicament or solvent for the powder. When it is to be used, a plunger is engaged with the recess 8 and the piston assembly is drawn back, so creating a partial vacuum in chamber 10, until the pistons 5, 6 reach by-pass recesses 11, 12, respectively. At this point air passes around piston 5 into chamber 9, so allowing the medicament therein to be drawn around piston 6 into the chamber 10. The closure cap 3 is then perforated by an injection needle. Modified arrangements described for admitting air to the upper chamber include an internal projection in the bore for deforming the plunger, a channel cut in the plunger stem where it passes through an otherwise sealed end-cap, a closure plug which is packed clear of the barrel by a projection on the plunger rod and a sealed diaphragm which is broken when the plunger is withdrawn.

Filed: 1967-08-10
Abstract: 1,194,054. Sheet feeding apparatus. USM CORP. 10 Aug., 1967 [11 Aug., 1966], No. 36754/67. Heading B8R. In a sheet feed aparatus in which the top ply of a stack of folded fabric plies is fed to a conveyer system by pick-off means the normally upwardly moving table supporting the stack is automatically momentarily lowered during each sheet feed in order to relieve any friction between the top ply and the remainder of the stack. Pile tables and supports.-The stack F, Fig. 1, mounted in a pallet 32 is placed on a vertically movable table 19 the chain actuation of which is controlled by limit switches such that the table is moved generally upwardly during normal feed with a momentary interval of downward movement during each sheet feed operation by the pick-off means 22. Photo-electric detector means associated with the conveyer system act to return the table to its lowest position in the event of either the absence or a jamup of fabric plies. Such an eventuality also effects shut down of the apparatus. Separators.-To assist the separation of each ply from the top of the stack ply fluttering means comprising a plate 36 and an air discharge tube 38 are provided. The pick-off means 22, Fig. 11, comprises a plurality of holders 33 each of which consists of a central diametral slot 24 therein by which the holders 33 are each slidably mounted on associated flatted bush members 25a secured to the shaft 25. The holders 33 are thus adapted to be rotated with the shaft 25 while sliding about the bush members 25a due to gravity. The holders 33 each comprise a slot in its periphery in which a portion of card cloth 34 is secured. Each portion of card cloth is adapted for unidirectional pick-off action. Rotation of the shaft 25 causes the card cloths 34 to move from a work engaging position, in which the fibres of the uppermost layer of the folded ply are engaged to a work release position, the shaft 25 being adapted for oscillatory movement to firstly move the holders 33 in one direction from the work engaging position to the work release position and then in an opposite direction to return the card cloths to the work engaging position. The pickoff means also comprises a belt conveyer of pulleys 26, 26a and belts 27 and a belt conveyer 23. A device for retaining the leading edge portion of each successive uppermost ply in a desired position until fed forwardly by the holders 33 comprises a tubular element 78 through which air is blown on to the leading edge portion held by a spring 79.

Abstract: 357,869. Safety razors. IRELAND, W. F., 55, Bath Road, Wolverhampton. Dec. 8, 1930, No. 36904. [Class 30.] In a clamped-blade type safety razor wherein the cutting edge of the blade may be adjusted over a wide range by varying the clamping tension, the blade is held firmly in any adjusted position by so forming the clamping members that the transverse radius of curvature of the edge parts of the blade is less than that of a circle through the outer edges of the clamping cap and the part thereof nearest the centre of the blade. In Fig. 1 the blade 8 is flexed to a triple curvature by means of a single central rib 13, or a double rib or row of projections on the clamping cap 5, the guard 1 being recessed at its central part and supporting the blade on raised parts 11. The middle part of the guard may be flat instead of recessed and may act as a stop for the blade, or the raised parts 11 may act as stops. The outer part 12 of the clamping cap has a curved inner surface beyond the raised parts 11, the intermediate parts being flat. The blade may be engaged by the edges of the clamping cap instead of by its curved surfaces, thereby giving a fivepoint support. In a modification the middle parts of the guard and clamping plates are flat, the rib 13 being omitted so that the blade is clamped, curved at its ends and flat at its centre. Alternatively, the clamping cap may have an elliptical clamping surface, or its outer curved parts may be flat and its middle part flat or curved. The flat face of the guard may be made narrower to increase the range of adjustment. The usual clamping screw is provided, together with aligning pins on either the guard or clamping plates, or in the case of slotted blades, a rib projecting from the rib 13.

Abstract: 358,361. Vehicles with removable bodies. KELLETT, W. P., 274, College Road, Fieldston, New York, U.S.A. Dec. 8, 1930, No. 36978. [Class 103 (iv).] In a railway freight wagon of the kind in which the goods are transported in a number of removable containers 3 adapted to be run on to transverse rails 2 on an intermediate truck 1, the sides of the containers are fitted with projecting fins 9, Fig. 3, adapted to engage under lips 5, 6<1>, 71, respectively on end and intermediate transverse beams 4, 6, 7 of the truck 1 so as to prevent longitudinal tilting of the containers, while lateral displacement thereof is prevented by means of pivoted locking blocks 15, 24 on the beams 4, 6, 7. co-acting with projecting flanges 21 on plates 20, 27 fixed to the container sides. Preferably the fins 9 are formed integrally with angle brackets 8 secured to the lower edges of the containers, while the lips 5, 6<1>, 71 are centrally disposed and of relatively short width so that the fins 9 are freed therefrom by a transverse displacement of the containers. The locking blocks 15 associated with the intermediate beams 6, 7 are, as shown in Figs. 2 and 4, disposed in open-ended pockets 11, 12 of castings 11 mounted on the ends of the beams, and are provided with elongated slots 13 and rounded corners 17 so that they may both pivot and slide on bolts 14 passing through the pockets 11. 12. The blocks 24 on the end beams 4 are of similar construction but operate in castings 22 with single pockets 23. When a container is to be run on to the truck 1 from one side, the blocks 15, 24 at that side are turned upwards, the container is run on the rails 2 until the flanges 21 abut against the turned-down blocks 15, 24 on the far side, and then the near side blocks are turned down behind the other set of flanges 21. Wedges 18, 26 cooperating with the inclined ends of the pockets 11, 12, 23 are employed to press the blocks 15, 24 against the plates 20, 27 and prevent their subsequent displacement. Specifications 275,982 and 297,422, [both in Class 103 (iv), Railway &c. vehicles, Body details &c. of], are referred to.

Filed: 1973-08-03
Abstract: 1430320 Clip, clamp and stud fasteners AEROQUIP AG 3 Aug 1973 [1 Sept 1972] 37040/73 Heading E2B A closure mechanism includes inner and outer telescoping closure sections 26, 27 each having a U-shape cross-section with a web portion connecting two spaced apart side flanges, pivots 23, 25 carried by the sections for connection to respective members 14, 15, e.g. of V-shape cross-section, to be drawn together and a bolt 37 extending through the inner section 26. A cross-pin 44 extends through apertures 43 in the section 27 and guide slots 32 in the section 26 parallel to the axis of the bolt, and a cross-pin 34 extends through apertures 33 in the section 26 and guide slots 42 in the section 27 parallel to the axis of the bolt. A nut 36 is threadedly engaged on the bolt and is drivingly engaged with one of the sections 26 and one end of the cross-bolt is connected by the pin 44 to the other section 27; axial advancement of the nut on the bolt causes relative movement of the pivots parallel to the bolt axis. As shown, the segments 14, 15 are pivotally connected by a link 18, the pin 25 being engaged in a notch in the segment 15; rotation of - the nut 37 applies a tension load to the bolt. Should failure of the closure mechanism occur, rupturing of portions 48 of the section 27 permits the cross-pin 44 to engage the outer ends of apertures 47 to limit opening movement of the coupler segments 14, 15, visual indication of such failure being given by movement of the nut away from the end of section 26. In a modification, the cross-pin 126, Fig. 7, is carried on a nut 127 which upon rotation of the bolt 118 is driven towards the head 121 of the bolt, the collar 117 forming a cross-pin 116 moving in the opposite direction whereby the bolt is placed in compression. Seating of the head 121 against the end 122 of the section 107 gives a visual indication of failure of the mechanism and that the coupler is in a partial open condition.
