Abstract: 746,515. Gun mountings. BREVETS AERO-MECANIQUES SOC. ANON. Sept. 15, 1954 [Oct. 15, 1953], No. 28490/53. Class 92. In order to maintain the balance of the mounting of a gun despite loss of weight due to expenditure of ammunition supplied from a magazine k, Fig. 3, a collector m for receiving spent ammunition components (spent cartridges and clips) is so arranged with respect to the trunnion axis x, that it has a mean line of leverage x<SP>2</SP> to this axis effective in the same direction as the mean line of leverage x<SP>1</SP> of the magazine to such axis and x<SP>2</SP> : x<SP>1</SP> are in the same ratio as the weight of a live ammunition component is to the weight of a spent ammunition component. Since in Fig. 3 the trunnion axis intersects the training axis the mounting about the training axis is not effected. In another embodiment shown in Fig. 4 the training axis ZZ is to the rear of the trunnion axis y so that the weight of the gunner is balanced by the weight of the gun and the centre of gravity of the magazine s is on the trunnion axis, but has a moment with respect to the training axis ZZ which is reduced as ammunition is expended. This is compensated by arranging' the collector t for spent ammunition components on the forward end of the turret p, the mean lines of leverage x<SP>4</SP> : : x' to the training axis ZZ being in the same ratio as the weight of a live ammunition component is to the weight of a spent ammunition component.

Abstract: 1288149 Making sparking plugs; forging; jointing by stamping CHAMPION SPARK PLUG CO 12 June 1970 [16 June 1969] 28550/70 Headings B3A B3H and B3Q A sparking plug, comprising a hollow tubular shell 10 and an insulator 34, is assembled by inserting the insulator in the shell and applying an axial force on the insulator to deform a shoulder 22 to provide an effective seat between the insulator and the shell. The shoulder 22 is formed either by inserting a die 28 into the shell or by machining. The insulator 34 is of vitreous material and it has a shoulder 38 which is preferably glazed and has a slightly different angle to the shoulder 22, the difference being at least 5 degrees. Sealing material 50, preferably a resilient material such as asbestos or talc, is packed in the space between the insulator and shell and tamped by a tool (52), Fig. 4 (not shown). A die 54 crimps the upper end 30 of the shell 10, which is then collapsed axially at a thin-walled portion 56 by the application of a high axial force to the die 54. As the shell collapses, the axial load is transmitted through the sealing material 50 to the insulator 34, which is forced downwardly to deform the shoulder 22 against the shoulder 38. Alternatively a metal gasket may be inserted in the shell over the portion 48 of the insulator and abutting its flange 36. The end 30 of the shell is crimped over the gasket and the portion 56 heated prior to being collapsed axially. A third assembly method comprises inserting the insulator and applying the axial force to deform the shoulder 22. Sealing material is then compacted between the shell and insulator, and the shell is then crimped.

IPC: B05C9/00
Filed: 1921-11-04
Abstract: 171,110. Paisseau, J. Nov. 4, 1920, [Convention date]. Coating-machines.-In a machine for coating beads with varnish or the like the beads are mounted on wires b, Fig. 3, attached at each end to spring-pressed hooks 17 which are rotated by gearing 19 from a shaft 20. The hooks are arranged staggered in two vertical planes one behind the other so that part of the varnish which escapes past the first row is intercepted by the second row. The varnish may be applied by a brush or by the nozzle 16, Fig. 1, of an atomizer 15 supported by a carriage 7. The carriage is moved on guides 8, 9 by means of a belt 28 which is jammed between a pivoted arm 33 and one or other of two springs 31, 32. The arm 33 is mounted at 34 on a pivot which also carries an arm 35 provided with a spring 39 which engages one of two pins 40 to force the arm 33 against the belt. The change over of the direction of motion of the carriage may be effected by hand or automatically at the end of each traverse. The walls of the receptacle containing the beads are removable and serve to collect the non-volatile parts of the varnish which escapes past the beads, the volatile part being removed by a fan. After a number of reciprocations in front of a row of beads the carriage is raised for the next row of beads. A spring hook 42 engages successive teeth on a rack 43 and is attached to a socket 13 moving on the vertical guide 1 and carrying the carriage 7. The lifting and reciprocation of the carriage may be performed automatically, as shown in Fig. 6. One or other of two pivoted arms 49 geared together engages the belt 28, being held in position by a spring-pressed detent 48 carried by an arm 46 pivoted at 45 and having studs 47 capable of engaging bell-crank levers 70, 71 at either end of the traverse of the nozzle carriage 7. Prior to the engagement with the bell-crank 71, a stop 76 on the carriage engages a stop 97 on a rod 56 to compress a spring 60 against a rocker arm 55. Simultaneously with the engagement of the arm 46 and bell-crank 71, a cam 85 on the carriage rocks a shaft 79 by means of a finger 83 and thereby withdraws a stop 86 from the path of the rocker arm 55 to allow it to swing suddenly to the symmetrical position shown, dragging with it the rod 67 to operate the bell-crank 71. The consequent rocking of the arm 46 shifts the belt grips. Simultaneously, one of the two teeth 96 on the arm 55 forces one of the hooks 94 on spring-pressed detent rods 90 which are in engagement with the teeth of a rack 46 and when released the hook moves up under spring action the distance of two teeth.
