Abstract: 469,772. Making paper bags &c. ROBINSON, Ltd., E. S. & A., DAVIES, K. W., and NICHOLAS, J. Feb. 4, 1936, No. 3366. [Class 94 (ii)] For the purpose of restricting vibration in bag-making machinery utilizing a tube-forming plate d, a breaker-plate and a beater arm, there is provided a supplementary roller e between the upper draw roll pair a, such supplementary roller being mounted eccentrically with regard thereto so that it may be adjusted as desired to co-operate with a roller f disposed below the tube-forming plate and preferably adjustably disposed on the side of the draw rolls remote from the cutting edge of the tube plate d. The carrying shaft l has an eccentric portion l<1>, the rolls a, a, e being mounted thereon and positively driven by gearing. In a modification, the roller e is driven by clutch mechanism from the carrying shaft and is mounted on an eccentric sleeve adjustable by gearing. In a still further modification, rotation of the carrying shaft is effected for adjusting the rolls a, eccentrically mounted, while adjustment as a whole, in the shaft bearings adjusts the supplementary roller.

Title: Multiple compartment ampoule and hypodermic syringe
IPC: A61M5/24
Filed: 1938-02-03
Abstract: 505,237. Ampoules; hypodermic syringes. LOZIER, M., and FROST, C. H. Feb. 3, 1938, No. 3449. Convention date, Feb. 4, 1937. [Classes 81 (i) and 81 (ii)] An ampoule containing in separated compartments liquid constituents of an injectable liquid, and adapted for use in a hypodermic syringe having a piercing member 20 carried by the plunger 17, the piercing member having a passage for transferring the contents of one compartment into another, comprises a tubular body closed by two slidable and pierceable plugs 12, 12<2> and separated in two campartments 13, 14 by a further slidable and pierceable plug 12<1>, the compartments being filled with the liquid constituents, the inner side of plug 12<2> being disposed inwardly of the end of the ampoule by a distance greater than the length of compartment 13. The passage in the piercing member 20 is constituted by an axial bore 22 opening laterally at 25. The member first pierces plugs 12, 12<1>, and then presses plug 12 against plug 12<1> transferring liquid in compartment 13 into compartment 14, and at the same-time forcing plug 12<2> outwardly until further movement is prevented by the front inner end of the syringe. Further movement of the plunger causes discharge of the mixed liquids when the piercing inner end of a double ended hypodermic needle passes through plug 12<2>. Plug 12<2> is formed with a cavity 26 to permit. entry of the projecting end of piercing element 20 so as to allow plugs 12<1> and 12<2> to contact. Alternatively, plug 12<2> may be without a cavity, and a cavity may be formed in plug 12<1>. The plugs may be of rubber, and may take the form of cup washers. The Specification as open to inspection under Sect. 91 comprises also a disclosure that one of the ingredients in the compartments may be in powder or semi-solid form, that the ampoule may be divided into more than two compartments, and that the piercing element 20 may be utilized independentlyof the plunger of the syringe. This subject-matter does not appear in the Specification as accepted.

Title: Improvements connected with marine mines
IPC: F42C14/04
Filed: 1940-03-01
Abstract: 572,509. Marine mines. JEFFERIS. M. R., and MACRAE, R. S. March 1, 1940, No. 3903. [Class 9 (ii)] A marine mine equipped with a parachute for sowing from aircraft has the firing mechanism armed automatically by a sliding assembly which is constantly urged to the arming position where elements of the assembly can be relatively displaced to fire the mine by the action of an inertia member when the mine is impacted. In the form shown, the mine comprises a casing 1 with a buoyancy compartment 3, a charge chamber 4, and a central tubular casing 12 containing the arming and firing mechanism. A detachable casing 60 contains a parachute or drogue 63 and a cork float 62, the float being connected to the mine through a cable looped through an eyelet 73<1> on a sealing disc 19 and the parachute being connected to the float by a cable including a link 65 which is disrupted after a time determined by a soluble plug to release the parachute. On launching the mine from aircraft, the cover 60 remains behind and the pull exerted when the parachute opens serves to remove the sealing disc 19. The firing mechanism comprises an assembly including a firing pin 39 having a disc 51 retained by arms 31 movable radially on pivots 32 and embracing a weight 30. The arms 31 are retained at safe by the wall of the tube 12, the firing assembly being urged upwardly by a spring 47, but being prevented from rising by a rod 27 bearing against the sealing disc 19 and having a piston member resting against a soluble plug 22. After removal of the sealing disc, water enters the chamber 20 and the firing assembly gradually rises as the plug 22 is dissolved until the upper ends of the arms 31 enter an enlargement in the tube 12. The firing mechanism is then armed and on the mine being impacted, the weight 30 can then operate to swing the arms about their pivots 32 to release the firing pin 39 on to the detonator 54 situated in the initiating charge 55.

A jet propulsion nozzle comprises an annular nozzle 14 defined by an external sleeve 13 overlying an inner wall 11 wherein are provided outflow apertures 12 for substantially radial passage of products of combustion from a propulsion charge to the nozzle, the sleeve overlying the apertures and being secured towards its front axial end to the inner wall and having different thermal characteristics so that on initial operation of the unit, the sleeve is forced away from the inner wall by the pressure of the combustion products and thereafter the area of the nozzle is varied as a result of the heat transmitted to the sleeve and the inner wall of different thermal characteristics. In a modification Fig. 2 (not shown) the sleeve is of composite form and comprises three rings of different axial length welded together at their leading edges. In another modification, Fig. 3 (not shown) the sleeve is cooled by the passage of coolant from a container in the front of the engine.

[Class 103(v)] A buffer coupling for adjoining mine cars comprises a socketed buffer, a loop like coupling link supported normally in a horizontal plane in and guided by the socket and connected pivotally at one of its ends to said buffer by a couplig pin, and balanced springs operating in tension between the buffer and link normally to centralize the link relative to the buffer and to project its other end and to permit of said link receding resiliently into the socket in the event of its projected end fouling any part of a mating buffer of an adjoining mine car. In the embodiment shown in Fig. 1, a link 5 projects from a socketed buffer head 1 under the action of springs 15 on the ends 14, Fig. 4, of a link carrier 13. A captive drop pin 9 depends through a hole 10 in the buffer and through the link 5 which is thereby retained. The projecting end 18 of the link 5 engages a mating buffer 2 and may be secured therein by a drop pin 21 slidable in a guide 19. A crank 27 connected by a rod 28 to the pin 21 is operable from the side 23, Fig. 11, of the car body by displacing the rod 24 axially against springs 11 and rotating the handle 26. A lug 29 is held, by the springs 11, behind an abutment 30 to retain the pin 21 in its inoperative position. In a further embodiment, Fig. 6, the couplings 1 and 2 are similar each comprising a link 5 and a drop pin 21 for coaction with the complementary elements of the adjoining car. The links 5, Fig. 8, project under the action of springs 15 on the link carrier 12. By the use of similar couplings all turnings of cars for coupling is obviated.
