Patent GB-1302209-A (GB)
IPC: H01H5/18
Filed: 1970-02-05
Abstract: 1302209 Thermal switches DANFOSS AS 5 Feb 1970 [14 Feb 1969] 5523/70 Heading H1N In an electric switch having first and second fixed contacts as 56, 57 Fig. 5 mounted on opposite sides of a spring strip 37 to face in opposite directions or in the same direction (shown) with one mounted on a "U" shape extension 55 and both engageable by movable contacts 40, 58 on spring strips 36, 38 when released by a snap-acting abutment member 60 having surfaces engageable with projections as 46, 59 on the strips 36, 38. The arrangement is such that only the low mass of the strips 36, 38 and contacts 40, 58 is subjected to rebound since the larger total mass of the snap-acting part 60 and plate (12) Fig. 1 (not shown) is free to continue its movement. The snap-acting assembly is more fully described in the Specification 1,295,034. The spring strips 36, 37, 38 are located between four support walls 32, 33, 34, 35 having knife-edge projections as 42, 43, 54 to support each block at three points. In the example of Fig. 1 (not shown) at least one on the knife-edge supports may comprise an adjustable set-screw (45) whereby the response of the blades may be adjustable. The ends of each blade are bent over to form flanges 52 for welding to terminals 48, 49, 50. In the example described the initial actuator for the snapacting drive may be a thermal bimetal (not shown) or a pressure bellows (23) Fig. 1 (not shown) with its response varied by an adjustable compression spring (25).

Abstract: 253,179. Hall, R. E. March 9, 1925. Moulding pulp. - Open-mouthed, seamless containers &c. of substantial depth are produced by moving foraminous moulds intermittently through a stationary bulk supply of pulp, drawing material against the exterior of the moulds by acting upon the interior thereof and intermittently subjecting the deposited mass to pressure to remove excess water. As shown, a rotary head 34 carrying moulds 35 is rotated intermittently by ratchet mechanism 28. 36 so as to immerse the moulds in pulp in a tank 1 for the greater part of its rotation; the moulds, after immersion, are brought, in turn, beneath a compression head 61 positioned by a toggle 73, 75. The rotor 34 is fitted with axial vacuum and pressure chambers connected to each mould by branch'pipes traversing valve chambers fitted each with a rotary valve integral with star-wheels 50 which are rotated by pins attached to the tank 1; the vacuum and pressure valves are aligned and are controlled by star-wheels on opposite sides of the rotor 34. Each mould comprises a brass casting 89, Fig. 10, perforated at 90 and grooved at 91, which is covered with a sheet 92 of monel or other non-rusting metal, in turn covered by gauze 94. The compression head 61 comprises a bell 79, Fig. 9, fitted with a rubber &c. bag 88 and with a plate 85, backed by springs 86, adapted to engage the bottom of the container during withdrawal of the head.

Title: Process for manufacturing hollow bodies, in particular projectile cases
IPC: B21D51/54
Filed: 1946-03-01
Abstract: 627,697. Making projectile cases &c. COMPAGNIE GENERALE DU DURALUMIN & DU CUIVRE. March 1, 1946, No. 6459. Convention date, Sept. 15, 1944. [Classes 83 (ii) and 83 (iv)] Forging ; extruding.-Apparatus for the manufacture of hollow bodies such as projectile cases, with a wall thickness decreasing from base to lips, in a single operation by die pressing, followed by extrusion, comprises a double die having two cylindrical coaxial holes, in one of which the blank is preliminarily shaped and a second hole of less diameter into which the blank is extruded, this hole being closed during the die pressing by a movable piston and comprises also a stepped punch having a frusto conical portion for die pressing and a cylindrical portion for extrusion, the movable piston serving at the conclusion of the extrusion operation as an ejector. The blank 8 is previously heated. As shown in Figs. 5 and 6, the blank is first shaped in the upper larger opening of the die 4 by the frusto conical portion 10 of the punch. The piston 6 closing the small opening of the die is then withdrawn and the cylindrical portion 9 of the punch extrudes the blank through the space between the portion 10 and the sides of the die to form the cylindrical sides 12 of the body. In a modification the extrusion is indirect. A blank 25, Fig. 8 is arranged on a fixed punch 23 with a mandrel section 24. The concentric pistons 26, 27 carrying a die 28 move downwards simultaneously and the blank is first pressed on to the punch 23, 24, thus obtaining the shape of the bottom of the case. The travel of the piston 26 is then halted and the piston 27 moves upwards to open the extrusion chamber. The piston 26 then completes its stroke and the extrusion of the case takes place. Finally, the piston 26 returns, carrying with it the case in the extrusion chamber, from which it is ejected by the piston 27. Air may be allowed to enter the extruded case either by way of a hole through the centre of the base, which hole may subsequently serve as a primer housing, or by way of an air passage through the punch and mandrel. This passage may be controlled by a valve 44, Fig. 12. Specification 469,550 is referred to.

Baffles and deflectors; blast apparatus; doors. -The ash-pit of a steam - generator or other f u r n a c e is partially closed by an horizontal d o o r 4 hinged to a cross-bar 2 which is so arranged that a restricted airpassage 3 remains between the bar 2 and the dead-plate E, through which passage the air for combustion is induced by means of superheated steam or air issuing from an horizontal and transversely-disposed sprayer 9 situated beneath the fire-bars, the sprayer directing the steam or air obliquely upward through the firebars F. A baffle-plate 6, which may be set at different angles, is attached to the furnace front above the passage 3 to guide the entering air in a definite path. The cross-bar 2 may be supported from the dead-plate E by bolts 1. The sprayer 9 is in connexion with a super-heater, preferably arranged in the side flue, the quantity of steam or air admitted to the superheater being regulable. The connexion pipe 7 between the superheater and the sprayer 9 passes through the air-passage 3. The natural draught through the air-passage 3 may be used when working on light loads.

[Class 106 (iv)] [Also in Group XXXVI] In a revolution indicator, synchroscope, or other instrument having a graduated scale with a length of more than 180 degrees, the bridge carrying the upper jewel bearing is made of transparent material to permit the pointer to be visible throughout the scale. A cylindrical instrument case 1 of plastic material carries a glass window 2 held by a bezel 3. A base 4, also of plastic material, has moulded into it three metal studs 13 which support the scale plate 12. The movable system comprises a movable coil, an iron vane, or a magnetised rotor 5 fixed to a staff 6, secured to which are the pointer 9 and cross arm 10 carrying balancing weights 11. A central hole may be provided in the scale plate to permit insertion of the member 5 after the scale plate has been fixed. The upper bearing 7 is carried by a bridge comprising a circular glass, plastic, or other transparent plate 14, which is supported on the studs 13 by screws 17 and cup washers 16 and is spaced from the scale plate by shouldered bushings 15. As shown in Fig. 3, the V-shaped jewel 18 forming the bearing 7 is retained in a screw 19 which is threaded into a bushing 20. This is spun over a metal washer 21 to form a rigid support for the bearing. The transparent bridge 14 need not be a circular plate, but may take the general shape of the instrument case. Also the bridge need not overlie the entire instrument but may comprise a flat bar extending diametrically across the instrument.
