Abstract: 482,714. Surgical syringes. NOVOCOL CHEMICAL MANUFACTURING CO. OF CANADA, Ltd. Oct. 1, 1936, No. 26654. Convention date, Aug. 12. [Class 81 (ii)] A medicament container of the " ampoule " or " cartridge " type, for use in hypodermic syringes, includes means for sealing an end of the container, a plunger positioned in the container near said end and forming with the container a relatively small compartment, undissolved medicament disposed in said compartment, the means sealing the container being adapted for unsealing to permit entry of a cannula, and the plunger being provided with means for attaching thereto a plunger bar insertable in the opposite end of the container. By " container of the cartridge type " is meant one consisting of a tube sealed by a closure puncturable by a cannula; by " container of the ampoule type" is meant one consisting of a tube having a tapered tip or nipple, which is broken off for insertion of the cannula. As shown in Fig. 2, the container consists of a tube 1, preferably of glass, formed at one end with a constricted neck 6 terminating in a flange 7 over which is fitted a cap 2 constructed as disclosed in Specification 391,177. The plunger 4, which is disposed near cap 2 forming small chamber 5a for the medicament in the form of capsules 5 or powder, consists of a centrally tapped member 15 embedded in rubber 16. It is formed with grooves 17 filled with a viscous medium such as glycerine. A cap 3 of rubber, gelatine, &c., is placed over the other end of tube 1. The tube 1, after removal of cap 3, is inserted through aperture 19 in the syringe, and is clamped therein by the engagement of a flange 24 formed on a plug 20 which is in screwed-threaded engagement with the upper part of the holder 18. A knurled portion 23 is provided whereby the plug is manually rotatable. A plunger bar 25 passes through the plug and its lower portion is screwthreaded for attachment to the tapped member 15 of the plunger 4. An enlarged portion 33 of the cannula 32 is clamped between a centrally drilled stud 30 on the lower part of the holder 18 and a sleeve 31. When the tube 1 is introduced into the holder 18, the upper end of the cannula pierces the cap 2, and after the plug 20 is screwed down, and the plunger bar 25 screwed into the plunger 4, liquid is drawn into the tube to dissolve the medicament. In Fig. 5, the lower closure cap consists of a plug portion 36 and a sleeve-like portion 37 flexed over flange 7. A central indentation 38 is preferably provided. The Specification as open to inspection under Sect. 91 comprises also a construction similar to that of Fig. 1, except that the plunger 4 is disposed at the end of tube 1 remote from the cap 2. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,044,684. Delivering measured quantities of liquid; container closures. WADDINGTON & DURAL (HOLDINGS) Ltd. July 15. 1963 [July 13, 1962], No. 26964/62. Headings B8N and B8T. [Also in Division F2] A liquid delivery tap 7 having an integral handle 9 and filling and emptying ports 15, 16 is slidably held within a sealing member formed with an external circumferential groove 2 by means of which it is located axially by a wall 14 of an aperture in a liquid container. A circumferential rib 5 engages the aperture wall radially when the sealing member is located and a shallow annular groove 6 permits deformation of the sealing member as the rib 5 is pressed inwardly by the aperture wall. The sealing member may be injection-moulded from polyethylene. The ports 15, 16 of the tap 7 are so positioned that one of them is always closed by the sealing member when the other is open. Reciprocation of the tap results in delivery of liquid from the container in a series of identical quantities. Movement of the tap inwardly of the sealing member is limited by an increased diameter portion 10 of the tap engaging with the lower side of a circumferential groove 6 in the sealing member. Before use, the handle 9 is crumpled in the recess formed at the top of the tap-and-sealing member assembly and held in the recess by a transit seal, Fig. 2 (not shown), which is torn away when the assembly is to be used.

Patent GB-206498-A (GB)
Title: Method of producing oxides of nitrogen
IPC: C01B21/26
Filed: 1923-10-29
Abstract: Nitrogen oxides are obtained by burning a cyanamide such as calcium cyanamide or a cyanide with air, oxygen or ozone.  The cyanogen compound may be mixed with other substances such as lime, quartz, a metallic oxide such as ferric oxide, or the residue of a previous operation.  The air or oxygen may be mixed with another gas such as carbonic acid, and may be employed at ordinary or reduced pressure. Preferably the cyanogen compound is pulverized and injected into a chamber or tube heated to a suitable temperature such as 600-1000 DEG C., but as the reaction is exothermic it is not necessary to supply heat when the reaction is started and it may be necessary to cool to prevent the temperature rising much above 1000 DEG  C. which would decompose the nitrogen oxides.  In an example the powdered material is injected into a heated tube in counter-current to a stream of air or oxygen.

Title: Improvements in electric knife switches
IPC: H01H1/54
Filed: 1925-10-30
Abstract: 244,058. Akt.-Ges. Brown, Boveri, et Cie. Dec. 8, 1924, [Convention date]. Mechanical switches with contacts reinforced electromagnetically. The electromagnetic action of a heavy current flowing through a knife switch prevents the switch from opening by increasing the frictional pressure between the knife blade and the fixed contact. According to the construction shown in Fig. 1, a slot d in the knife blade b engages a pin c on the fixed contact a and one or both of the insulators f, g are mounted so as to be slightly movable. A heavy current tends to force the insulators f, g apart and hence causes the pin c to press with great force against the side of the slot. In a modification, the slot d is inclined, and in another modification a pin on the knife blade engages the outer edge of the contact a. According to the construction shown in Fig. 3, the fixed contact consists of two U- shaped springs. The outer arms of the springs are held fast by a member e and the current flowing through the springs causes their inner arms to squeeze the knife blade b. Instead of the member e a bolt passing through the springs may be used, which also co-operates with a slot in the knife blade as in Fig. 1. In a further modification, two knife blades connected by a pin embrace a double U-shaped fixed contact.
