Abstract: 591,604. Valves controlled by auxiliary valves. ALLMANNA SVENSKA ELEKTRISKAAKTIEBOLAGET. April 5,1945, No. 8412. Convention date, April 24, 1944. [Class 135] A valve for controlling the supply of compressed air to operate an electric-circuit breaker is provided with an auxiliary valve 17 having a spring-urged closure member 27 which, in its upper position, co-operates with a seat 29 to cut off communication between a chamber above the main closure member 3 and the atmosphere. At the same time compressed air from an inlet 14 enters the chamber through a pipe 18 and assisted by a spring 23 holds the closure member 3 on to its concentric, co-planar seats 20, 21. To open the main valve, the auxiliary valve, which may be operated either by hand, pneumatically or by an electromagnet, is moved to its lower position to close the end of the pipe 18 and open the chamber to atmosphere to relieve the pressure therein and permit the pressure on the underside of the main closure member to overcome the spring 23. In a modification, the concentric seats 20, 21 are arranged in different planes.

Abstract: 1,235,627. Rolling mills. E. W. BLISS CO. 17 Feb., 1969 [27 March, 1968], No. 8501/69. Heading B3M. A rolling mill incorporates retractable spacers between the chocks of the work rolls, the spacers being extendable to hold the chocks apart during roll-charging operations and being lockable in their extended positions. Each spacer includes a cylinder 38 located in a vertical bore 32 in a lower work roll chock 24, the the cylinder being attached to a piston-rod assembly 42. By supplying air to an inner cylinder 40 in which the assembly moves, the cylinder 38 can be raised from a retracted position. To remove the work rolls from a 4-high mill, the rolls are first raised by a pneumatic assembly 26 and are separated from one another by balancing jacks. Each cylinder 38 is then raised and is held in this position by a spring-loaded bolt 54. The bolt has a keyhole shaped slot in it (Fig. 2B, not shown) which prevents the cylinder 38 from dropping from the position shown. A wheeled dolly is inserted between the chock 24 and the backing roll chock 77 to allow removal of both work rolls from the mill stand. A tapered projection 72 of the bolt 54 causes the bolt to be retracted when the chock 24 is lowered relative to the chock 77, thus allowing the cylinder 38 to be retracted. The cylinders 38 can be located in the upper work roll chocks rather than the lower ones.

Title: Improvements in and connected with electric tumbler switches particularly for alternating current circuits
IPC: H01H23/28
Filed: 1943-06-01
Abstract: 565,960. Tumbler switches. CRABTREE & CO., Ltd., J. A., McLOUGHLIN, H. F., HARRISON, B. V., and MORGAN, R. W. June 1, 1943, No. 8743. [Class 38 (v)]' In a tumbler switch of the kind in which an initially-formed short gap is maintained for a substantial part of the opening movement prior to final separation to produce the full isolating gap, the movable contact-carrier is tiltable about a pair of spaced fulcra and rests upon both during a large part of the opening movement. The fulcra may be formed by a bent part of a contact plate k bridging the contact members l, o and carrying a stud n normally engaging contact o, the plate pivoting about the fulcrum k<2> to form the short gap and, after resting on both fulcra, pivoting about the fulcrum k3 to produce the isolating-gap. A stud m passing freely through k, l helps to locate the parts. In a modification, Fig. 9 (not shown), the fulcra may be formed by corners of an upward projection from the base or, Fig. 15 (not shown), by an upwardly-cranked tip of contact l, the plate k being plane in both cases. In another form, Fig. 18, employing an upward projection 2 from the base, transverse bridging contacts 1 on a carrier may be pressed upwards against the under-surfaces of pairs, of fixed contacts 2a forming a two-way arrangement, by means of springs 3 on either side of the projection. A snap-action is imparted by a spring c abutting on shoulders of a U-shaped plate i embracing the dolly-pivot d and a pin f on which the other end of the spring bears. The pin f is further received in recesses g of both limbs of a U-shaped member a fixed to the dolly, and in recesses h<3> in insulating blocks h carrying the plates k. In the event of sticking of the parts, the blocks h are positively driven by the bracket a. A slightly-modified form of snap-mechanism is also described, Figs. 16, 17 (not shown). The Specification refers also to ceiling switches and shows, with the aid of drawings, how the contacts are interconnected for two-way and single- and double-pole working.

Filed: 1974-02-28
Abstract: 1438234 Calcining gypsum RHEINSTAHL AG 28 Feb 1974 [14 March 1973] 9177/74 Heading C1A Calcined gypsum suitable for plasterwork is produced by burning gypsum raw material (calcium sulphate dihydrate) the burnt material being carried in a stream of gas and cooling firstly to a temperature higher than 120‹ C. by means of steam-containing gas and, secondly, to a temperature below 80‹ C. by means of air. The waste gas vapours from the burning process may be used as the coolant for the first cooling stage. The process may be carried out in apparatus comprising (see Figure) preburners (2), carrier gas source combustion chamber (1), first burner (3) first cooling centrifugal separator (10), second cooling centrifugal separator (11) dust separator (17) and discharge conveyer (19). In an example, finely granulated calcium sulphate dihydrate is delivered from hopper (4) into pipe 6. The material initially burnt in the pre-burners (2) can be supplied by a regulating member 7 wholly or partly by pipe (8) to post-burner (3), or by pipe 9 direct to the first cooling cyclone (10) bypassing the first burner (3). The pre-burning stage (2) calcines the material at up to, e.g. 260‹ C. and the first-burning stage (3) calcines at up to, e.g. 420‹ C. The cooling separator (19) is charged with steam containing gas, especially with a mixture of waste gas vapours and air, and the pre-cooled material travels via pipe 14 to the second cooling separator (11) which is charged with cold air through pipe (14). The material is discharged via conveyer worm (19). In the first cooling stage, the material is cooled, e.g. to 140‹ C. and in the second stage to about 60‹ C. The method is especially suitable for producing gypsum with controlled setting behaviour for plaster-work.

Abstract: 102,454. Merriman, E. June 29, 1916. Manual exchange systems.-In a system in which a line terminates at a main instrument and also at an extension instrument, a switch is provided by which either instrument is connected to line and the ether disconnected from line, according as the switch hook at the extension instrument is in its raised or lowered position. The switch is contained in a casing which can be readily attached to a table instrument, and is operated by a plunger which is depressed when the switch hook is in its lower position. In the system shown in Fig. 2, in which the main and extension instruments cannot communicate, the exchange line ends in the springs S', S<2>, which are normally connected to the main instrument M. On receipt of a call, the depression of the key J at the main instrument rings the bell D at the extension instrument, and when the receiver of this instrument is removed from its hook, the exchange line is connected over springs d', d<2> to the extension instrument E. Signals T', T<2> indicate to the extension and main subscribers when the line is in use by the other party. In the system shown in Fig. 3, communication between the two instruments is effected by the use at the main instrument of a three-position key controlling the contacts 1<a>, 1<b>, 2<a>, 2b, 3a, 3b. In the normal position of the key, as shown, the exchange can call the main instrument over the circuit L<1>, c', 2a, G, F, K, 2b, c<2>, L<2>. If the call is for the extension instrument, the switch is moved into its second position, in which springs 1<a>, 1<b> engage their inner contacts, and springs 2<a>, 2b their outer contacts. In this position, the bell F is bridged across the exchange line L', L<2> to hold it, and the main and extension instruments M, E are connected. When the extension party replies, the switch at the main instrument is released, and the exchange line is connected to the extension instrument over contacts d<1>, d<2> and 1<a>, 1<b> in their normal position. If the main station M wishes to speak to the extension without holding the exchange line, the key is moved into its third position, in which the springs 1<a>, 1<b>, 2<a>, 2b engage their inner contacts, and the springs 3<a>, 3b their outer contacts. While the stations M, E are connected over the springs 1<a>, 1<b>, the exchange can ring up the main station over springs 3<a>, 3b.
