Patent GB-681098-A (GB)
Title: Hypo-jet injector
IPC: A61M5/30
Filed: 1949-07-07
Abstract: 681,098. Hypodermic injectors. DEHN, S. G. (Scherer Corporation, R. P.). July 7, 1949, No. 18014/49. Class 81 (ii). A hypodermic injector for injecting medicament without the aid of a tissue piercing needle comprises mechanism for operating the plunger whereby a two stage medicament jet is projected the first stage being at a higher velocity than the second stage, and the second stage being sufficient to effect injection at a lower pressure than the first stage. As shown, Fig. 1, the hypo-jet injector comprises a barrel 34 having a lower head 36 connected thereto by screw threads 38. A recess 40 in the head 36 receives the flange 14 of an ampoule A which is held by a retainer plate 42 pivoted at 44 and latched at 46. From a primary cup 54, slidable within the barrel 34 and normally urged downwardly by a spring 56, depends a primary plunger 62. This plunger is slidable through a tubular member 64 which is an extension of a secondary cup 60 slidable in the head 36 and forms the secondary plunger. This plunger 64 is biased upwardly by a light spring 68. A pull rod 70 connected to the cup 54 and having a latch shoulder 74 is provided for compressing the spring 56 to the position shown in Fig. 1. The shoulder 74 is engaged by a latch plate 76 biased to coact by a spring 78. In operation the injector is usually held at right angles to the skin surface and the ampoule is pressed against the epidermis in order to effect a hydraulic seal between the edge of the jet orifice 16 and the epidermis. On release of the latch shoulder 74 the spring 56 propels the primary cup 54 until it strikes the secondary cup 60 and during this time the primary plunger 62 is acting on the follower F, causing a very high pressure tissue piercing jet to issue from the orifice 16. This high pressure drops when the cup 54 strikes the cup 60 as the spring 56 then moves both primary and second ary plungers in unison. Injection is complete when the cup 60 abuts the upwardly projecting boss 65 formed in the head 36. In a modification the cup 54 is held higher in the barrel 34 than is shown in Fig. 1, when the injector is cocked, thereby raising the primary plunger 62 out of contact with the follower F. On release of the cup 54 the travel of the plunger 62 produces an impact against F which is added to the initial high pressure stage of the operation. The primary plunger 62 may have a bullet-shaped end for engaging the follower F. In a further embodiment, Fig. 9, a single plunger 63 is used, the two stage jet action being effected by very stiff spring discs 90 and the spring 56. This embodiment may be modified by utilising a heavy coiled spring in lieu of the discs 90. Specifications 568,237 and 681,097 are referred to.

Abstract: 1,007,608. Making corrugated tubes and cable sheaths. HACKETHAL-DRAHT-UND KABEL-WERKE A.G. May 10, 1962 [May 16, 1961; Feb. 1, 1962], No. 18030/62. Headings B3A and B3E. In an apparatus for producing corrugated weld seamed thin metal tubes, for example cable sheaths, wherein the tubes are formed from strip by rollers, the abutting edges are welded and the welded tubes are moved by a draw-off means interposed between a corrugating device for the welded tubes and the welding head to prevent the corrugating torque being transmitted to the welding point, the draw-off means comprises gripping jaws having guide rollers therein for engaging stationary guide rails, one roller being eccentrically adjustable and the other displaceable on rocker arms. Two jaws 1a, 1b are brought together to grip the welded tube by the engagement of guide rollers 3a, 3b with stationary guide rails and the jaws are carried on endless chains. The jaws carry liners 14a, 14b replaceable for different tube diameters. The roller 3a is adjustable on an eccentrically arranged shaft 5 in jaw 1a and the roller 3b is carried on a shaft 6 mounted between two arms 8, 9 pivoted at one end at 7 to the jaw 1b and resiliently connected at the other end through a member 11 connected to a spring plate 13 whose tension is adjustable by a screw 12. Adjustment of the roller 3a permits clamping force adjustment. The end of the shaft 5 may carry a disc 18 graduated in clamping pressures. The carrier for the jaws may be divided into an upper part and a lower part secured to the endless chains, the two parts being dovetailed together on a slideway. A compression spring is provided between the parts and an elbow lever is pivoted to a projection on the lower part and to a projection on the upper part, the end of the lever carrying a roller. As the jaws close on to the tube the roller rides up on a rail to lock the parts together and when the roller rides off an adjustable part of the rail the upper part is displaced against the spring, the arrangement being such that the jaws exert no draw-off force as they open.
