Title: Fire resisting cabinet
IPC: E05G1/024
Filed: 1945-07-28
Abstract: 596,521. Safes. SHAW-WALKER CO. July 28, 1945, No. 19357. Convention date, July 3, 1944. [Class 44] A fire-resisting container 10 comprising a metal casing 14 lined with a heat-resisting material 15, such as gypsum plaster, has a relatively thin layer of insulating material 19 expansible under heat, such as vermiculite, disposed in its natural unexpanded state between the casing and lining, so that, when the container is exposed to fire, the effective thickness of the insulating lining is increased (shown in part in Fig. 4), since the material 19 expands and fills the spaces which would otherwise be formed between the casing 10 and lining 15. An inner metal shell 16 (Fig. 4), to which vermiculite may also be applied, may enclose the lining 15 which may be formed by moulding or in separate slabs. The vermiculite, in its natural granular state and mixed with a light binding material, may be applied with a trowel or may be sprayed on to either the inner surface of the casing 14 or the outer surface of the lining 15, before the parts are assembled. Alternatively, when the main lining 15 has been inserted in separate slabs spaced slightly from the casing 14, the vermiculite, in its natural dry state or combined with an adhesive binder, may be poured from a hopper into the spaces so formed ; it may also be employed along the joints of the slabs.

Title: Control mechanism for reversible electric motors
IPC: H02P23/00
Filed: 1952-08-06
Abstract: 708,414. Control of A.C. motors; controllers; thermal switches; centrifugal switches. GENERAL MOTORS CORPORATION. Aug. 6, 1952 [Aug. 27, 1951], No. 19748/52 Classes 38(3) and 38(5) Relates to means for etfecting continuous automatic reversals of a split phase induction motor 20 involving the use of a cam shaft controller 70 which is driven by a pilot motor and is adapted to be manually operated in the same direction that it is driven. The operating lever 71 of the controller is moved in a clockwise direction to close contacts 81, 82, and energize the pilot motor winding 72 so that the controller is rotated clockwise at a given rate. The running winding 22 of the motor 20 is energized through contacts 81, 82, and 91, 92, the circuit to the starting winding 21 being completed through capacitor 110 as well as centrifugallycontrolled contacts 27. 28, and cam-operated reversing switches 102, 103. When the motor 20 reaches a predetermined speed, a centrifugal switch opens contacts 27, 28, and closes contacts 29, 30, whereby the starting winding is disconnected but the running winding is maintained energized independently of the contacts 91, 92. After the controller has operated for a predetermined period, cam 100 shifts the reversing switches 102, 103, and, when contacts 91, 92, and 96, 97, are next closed, the starting winding 21 is reversely energized through a thermally-operated switch 60 so that the motor 20 is braked to a standstill and then reversed. When the motor speed drops to a given value during braking the contacts 27, 28, of the centrifugal switch are engaged and the circuit of the starting winding is completed therethrough, the switch 60 being opened at a predetermined interval after reversal. At the end of a cycle of operations, involving a number of reversals, the cam 80 opens contacts 81. 82. The motor 20 may drive a laundering machine. The movable contact 63 of the switch 60 is fixed to a blade 62 having a biasing finger 67 which may be moved to either side of the blade by means of a thermo-electric wire 68. The contacts 63, 64, are opened when a current of predetermined value and duration passes through element 68 so causing the wire to expand and allowing a spring-supported actuator 66 to reverse the biasing effect of the finger 67 upon the blade 62. The centrifugal switch, Fig. 2, comprises weights 52 adapted to move outwardly from the motor shaft 42 against the effect of spring 51. The washer 53 then traverses the declining surface 55 of member 33 so that spring 45 causes the member 33 to pivot about contacts 27, 37, until, at a predetermined speed, contacts 27, 37, are opened and contacts 29, 39, are closed.

A work-holder for milling or drilling comprises hollow outer and inner co-extensive spindles 32, 38, the outer spindle having an abutment 54 to retain a collet 48 in a conical seating in the inner spindle which is axially movable, and pins 34 extending from the outer spindle, through slots in the inner spindle to a sleeve 36 within the latter.  The inner spindle 38 is moved axially to close the collet 48 by moving a handle 88 connected to a yoke 86 engaging a cam sleeve 72 which forces balls 70 against a conical surface 68. Resilient means 50, 52 release the collet when the handle is retracted. The outer spindle 32 carries an index plate 94 having a series of holes selected by withdrawing screwed plugs 102. Co-operating with the holes is a spring-pressed plunger 104 which can be withdrawn by a handle 116. The spindle can then be rotated by moving a handle 144 connected to a pawl-carrying collar 124. The work is located axially by a stop 152.

Arc lamps.-In a kinematograph or other lamp, the electrodes are fed by an electric motor connected in shunt to the arc through a resistance which can be adjusted to vary the length of arc maintained by the motor. A steadying-resistance and a hand-switch may be arranged in series with both the arc and the motor. The motor 31, adjustable resistance 40, and gearing may be mounted in a frame 32 attached to the lantern A. Transmission is effected by means of three worm gears 30, 27, 19. Two universal joints 12, 14 and an extensible coupling 13 are interposed between the shaft of the third worm-wheel 18 and a pinion 9 gearing with the electrode-holder racks. Two universal joints 23, 21 couple the second wormwheel 26 and the third worm 19, which is mounted in a bearing on a lever 34. A cam 38 may be turned by hand to force the lever and worm away from the wheel, against the action of a spring acting on the lever. A hand-wheel 17 on the shaft of the third worm-wheel 18 can then be operated to strike the arc,

Abstract: A process for the catalytic hydration of olefins to the corresponding alcohols over phosphoric acid catalysts, comprises the step of bringing crude reaction product issuing in the vapour state from the reaction zone to its dewpoint or almost to its dewpoint before passing it into a heat exchanger by introducing liquid water and/or said corresponding alcohol, or steam in sufficient quantity into the vapour stream.  The heat exchanger may be employed to transfer heat from the crude reaction product to the water and/or the olefin reactants and the material introduced into the vapour stream may be condensed reaction product obtained from the heat exchanger.  An example describes the production of ethyl alcohol from ethylene.

[Class 56] [See also Group XII] A frame for holding one or more glass sheets in an approximately vertical plane during tempering comprises two horizontal members, one above and one below the sheet, one of which carries the weight of the sheet while the other is provided with means for restricting transverse movement of the sheet. The frame comprises vertical standards 13 mounted on a truck 10 and connected by a cross-member 14. A crossmember 16 is movable along the standards 13 and can be locked in any position of adjustment. The glass sheets 18 are suspended by tongs connected by universal joints 24 to the ends of bars 23, each of which is suspended from the crossmember by a universal joint 22. To prevent the sheets from swaying, pads are arranged close to their lower edges, the pads being carried by members 35 mounted on rods 29 attached to the cross-bar 16. One of the rods can be rotated to permit removal of the sheets. In a modified construction, the members 35 are mounted on the cross-bar 16, and some of the members can be swung aside when the sheets are to be removed. A second row of sheets can also be suspended from the member 16. The glass may be heated in a furnace 51, Fig. 2, provided with electrical heating elements 52, and with metal baffle walls 54 that form a compartment 55 through which the truck 10 with the glass sheets is moved. The opening at the bottom of the compartment 55 is closed by providing troughs 57 to contain sand or similar material. The lower part of the glass-supporting frame is provided with downturned flanges 59 whch run through the sand and provide the required closure.
