IPC: C04B26/30
Filed: 1950-04-24
Abstract: A moulding composition for clutch and brake linings and grinding sheets comprises a partially condensed co-hydrolysate of a mixture of 90-70 mol. per cent of a phenyl silicon trihalide and 10-30 mol. per cent of an ethyl silicon trihalide (preferably the chlorides), and a filler comprising asbestos or a mixture of asbestos and magnesium oxide.  Curing catalysts referred to are the lower alkylol-amines (many specified), the lead, cobalt or manganese salts of the naphthenic acids and 2-ethyl lead hexanoate.  Preferred ratios are 80 per cent phenyl and 20 per cent ethyl silicon trihalide, with from 1 to 4 parts of asbestos or asbestos and magnesium oxide for each part of solid hydrolysate.  Suitable magnesium oxide/asbestos ratios are from 1 : 1 to 1 : 7.5 parts by weight.  Mixing may be facilitated by using a ketone to wet all the dry ingredients or the solids may be incorporated into an ether solution of the hydrolysate.  The solvent is removed by evaporation.  The hydrolysate may be prepared by mixing the silicon halides with ethyl or isopropyl ether and the solution added to a mixture of ice and water, the cohydrolysate being recovered as a solution in ether and being subsequently dried and comminuted before or after adding the powdered filler.  The dry moulding composition is moulded at 250-350 DEG  F. and 2000-4000 lbs. pressure for 1-2 hours with a final cure of 8-16 hours (less with a curing catalyst) at 475-550 DEG  F. after removal from the mould.

Title: Gas taps
IPC: F16K31/56
Filed: 1973-03-02
Abstract: 1425891 Valves EWARTS Ltd 30 Jan 1974 [2 March 1973] 10400/73 Heading F2V A rotary plug valve, for use with natural gas, has a positive positioning device, comprising a cam plate 26 and a pair of spring loaded detent balls 32, to ensure that when the valve is moved from an "off" position to a "minimum flow" position giving a stable flow it cannot be inadvertently set to a position intermediate these two positions. The cam plate is keyed to an operating spindle 20 which is coupled to a conical valve plug 14 by means of a pair of lugs 18 on the spindle which engage in seats in the plug. A spring 22 urges the spindle outwardly from the plug so that in the "off" position the lugs 18 engage in recesses 44 in a cover plate 34 to prevent rotation of the plug until an operating knob (not shown) attached to the shaft has first been depressed. To open the valve, after first depressing the knob, the spindle is rotated in anti-clockwise direction from the "off" position shown in Fig. 3 so that the balls ride out of the recesses 50 in the cam plate until they snap into the recesses 52 which correspond to the "minimum flow" position of the valve. If the knob is released before this position is reached the spring-loaded balls will drive the cam plate, and hence the valve, back to the "off" position. Further anti-clockwise rotation allows the balls to ride along the circular surfaces 56 of the cam to permit the valve to be set in any flow position intermediate the "minimum flow" position and a "full flow" position in which the balls engage further recesses 54. In the "minimum flow" position gas may be divided through a by-pass passage containing an adjustable valve, preferably in the form of a plug having a pre-determined clearance around it.

Title: Improvements in valves or switches
IPC: G05D23/08
Filed: 1947-04-18
Abstract: 631,893. Thermally-actuated valves. WILSON CO., H. A. April 18, 1947, No. 10429. Convention date, Sept. 17, 1940. [Class 135] [Also in Group XXXVII] In a thermally-actuated valve, the free end of a spring attached to the valve bears eccentrically against a member connected to and rotatable by the thermal element so that the valve is opened or closed by the rotation of the said member. As applied to a valve controlling the flow of fuel to a burner, a thermal element 32 consisting of a bi-nickel helix can rotate a shaft carrying a friction-disc 22. The valve 15 is carried by a lever 17 of springy material which is provided with lateral arms engaging in grooves in the valve housing to constitute a fulcrum for the lever at the point 20A, and the free end of the lever is bent into #-form and bears eccentrically against disc 22. When the latter rotates in a clockwise direction, it will engage the end of lever 17 and pull it up past the dead-, centre position shown in the Figure, and the other end of the lever will then snap downwards to close the valve. During any further clockwise rotation of disc 22, the end of lever 17 will merely ride over the surface of the disc, but the first anti-clockwise rotation will carry lever 17 along with it until the lever re-passes the deadcentre position and the valve snaps open. The movement of the valve is limited by an adjustable screw 12, and the fulcrum 20A may be made adjustable by forming the grooves in a sliding plate. A gasket 24 is provided. The temperature at which the valve snaps over can be varied by adjusting nut 25. In modifications, the end of lever 17 engages in a notch in disc 22 and does not ride over the surface of the latter, or the disc 22 may be replaced by a notched lever.

Filed: 1923-04-18
Abstract: 199,699. Schember, K., and Joksch, R. June 22, 1922, [Convention date]. Apparatus fitted to cranes; indicating-mechanism; printed records, apparatus for giving.- Weighing-apparatus is controlled from a distance by mechanical connections, and the balance or otherwise of the apparatus is indicated to the operator at the distant station by electrical means, so that he may observe and record the result of the weighing. As applied to a crane, the weighing-apparatus is suspended from the crane hook 16 and the load is balanced by the adjustment of poises 4, 5 along a beam 1. The mechanism for adjusting each poise is similar and, as shown for the poise 4, comprises a horizontal rack 11 with adjuster 6. The rack is moved by a gear wheel 13, rope 23, gear wheel 21, rack 20, toothed segment 19 and a hand lever 18 in the operator's cabin. The gear wheel 21 is provided with a reading scale. Near the end of the beam 1 are two electrical contacts 27, 28 which cause the illumination of one or other of two lamps 27L, 28L in the operator's cabin except when the beam is in its equilibrium position. The operator is thus able to adjust the poises by means of the handles 18 until the load is balanced, and may then read off the weight from the indications on the gear wheels 21. By turning a handle 31 the operator may obtain a record of the weight on a strip of paper by means of type arranged on the racks 20. The record may only be obtained when the beam 1 is in equilibrium position, as otherwise the core 33 of a solenoid 32 in circuit with the contacts 27, 28 obstructs the movement of the handle 31.

Abstract: 165,977. British Thomson - Houston Co., Ltd., (General Electric Co.). April 19, 1920. Induction relays; springs, arrangement of.-In order that the contact member of a relay shall move at a predetermined current rapidly throughout its range to the closed positon without intermediate ' floating ' and rapidly return on a reduction of current, means are provided for reducing the effect of the counter-torque element when the contact-member begins to move, and to restore the counter-torque when the current falls off. In the arrangement shown in Fig. 1, the motor element of an induction-disc relay consists of a winding energized from a secondary winding of a transformer in the line, and a winding 6 supplied from another secondary through a solenoid 13. When the current in the windings 6. 7 is adequate to cause the disc to rotate towards the closed position of the contacts 10, 11, the solenoid 13 raises its core and unwinds the control spring 9 reducing the control torque. When the current falls off the plunger falls back and the relay is returned to the off position by the full control torque. As applied to a three-phase reverse-power relay shown in Fig. 2, the normally fixed end of the control spring 26 is secured to a. pin carried by a disc segment 27 acting as the armature of a magnet energized by a winding 34 in series with one of the motor elements 21, 22, 23. The current which produces initial movement of the relay causes movement also of the segment against the action of its spring 32 in a direction to take tension off the main control spring 26 so that the discs move through their complete range to close the relay. When the current falls off the control 26 is restored.
