Title: Improvements in or relating to electric safety switching devices, more particularly for fluid-cooled instruments
IPC: H02H5/08
Filed: 1938-02-25
Abstract: 511,862. Actuation of switches. FOSTER INSTRUMENT CO., Ltd., and FOSTER, C. E. Feb. 25, 1938, No. 5997. [Class 38 (v)] An electric switch which is operated upon cessation of a stream of fluid such as water or air used for cooling pyrometers or other instruments, has a lever 3 pivoted at 4 with one arm 3b which carries a mercury switch 5 and another arm 3c which carries a beaker 6. Cooling water 7 flows from a pipe 8 into the beaker which empties through a hole 9 of a size not quite sufficient to carry away all the water. The beaker therefore fills and overflows at a lip 6b, and the arm 3 rocks to close the switch 5. Upon diminution or cessation of flow the beaker empties through the hole 9, the arm 3 rocks to the dotted position, and the switch 5 opens and an alarm circuit may be operated. In another arrangement, gas flows through a bellows kept extended by a satisfactory flow, but which closes to operate a switch upon diminution of the flow, by gas escaping from the bellows through a small hole. The time taken to empty the beaker or bellows provides a time delay in the operation of the switch.

Title: Improvements in or relating to briquetting
IPC: C10L5/10
Filed: 1953-03-05
Abstract: In a process of briquetting materials such as ores and mixtures of ores and fuels there is used as a binding agent a dispersion comprising a hot coal tar pitch or other pitch containing aromatic hydrocarbons such as wash oil pitch, water, a water-dispersible clay-like material other than bentonite, and at least 0.5 per cent and preferably from 1 to 4 per cent by weight based on the dispersion of one or more cyclic compounds containing two or three rings.  The base material which may contain 15-25 per cent of moisture is mixed with the binding agent and shaped, the shaped articles may then be air dried or dried by heat or be subjected to a heat treatment, e.g. sintered at 600-700 DEG  C.  The water-dispersible material may be kaolin and suitable cyclic compounds are naphthalene, anthracene and phenanthrene.  When naphthalene is used it may be added in the form of a condensate obtained by cooling coke-oven gas.  This condensate may also be used to wet the materials to be briquetted.  Materials capable of being briquetted are dry and wet ores, for example blast furnace dust, ore dust, roast pyrites, blast furnace dust sludge and ore flotation sludge alone or in conjunction with a fuel such as coke slack sludge, coke slack, coal dust and fine anthracite dust.  In an example, 1 kg. of water or gas condensate are mixed with 1.3 kg. of powdered kaolin and 2.5 kg. of hot coal tar pitch which contains 2 per cent of naphthalene or anthracene, based on the entire dispersion, are added, the temperature being kept at 60-80 DEG  C. Finally a further 2 kg. of water or gas condensate are added to the mixture.  The resulting dispersion is added to a mixture of 26 kg. of coal dust and 42 kg. of coke fines which have been moistened with 8 kg. of gas condensate.  The mixture is shaped and dried at room temperature for 1-1 1/2 days.

Abstract: 497,900. Regulating; re - admitting exhaust gases. HAPKINS, D. N. Feb. 28, 1938, No. 6280. [Classes 7 (ii) and 7 (vi)] During overrunning, the flow of mixture to the engine cylinders is prevented by an auxiliary throttle valve which is closed bv the action of the suction on a diaphragm carrying a valve which is moved to transmit the suction to a piston connected to the auxiliary throttle. A block 22 inserted between the carburetter and the intake manifold carries an auxiliary throttle valve 50 mounted on a shaft 51 connected by rods 55, 37 to a piston 32 in a cylinder 31. During overrunning with the main throttle closed, the suction in the intake manifold, transmitted through passages 70, 85, moves a diaphragm 79 carrying a valve 76 to the left to establish communication between the passage 70 and the cylinder 31 ; the suction then moves the piston 32 to shut the valve 50, and simultaneously a piston 40 connected to the piston 32 uncovers an annular groove 44 to admit exhaust gases, delivered past a filter 39, through a passage 42 containing an adjustable valve 63 into the intake manifold. When the main throttle is opened, a cam plate 102 adjustably connected to the control arm 16, opens a ball valve 99 to admit air through a passage 93 to the cylinder 91 to permit the valves 50, 40 to return to their normal positions. To prevent stalling, an orifice in the valve 50 maintains a small depression in the carburetter when the valve 50 is closed when the main throttle is opened. An auxiliary diaphragm 91 prevents leakage around the valve 76. Specification 454,615 is referred to.

The intermediate portion of the tubular cylinder may be radially displaced by radial expansion of the intermediate assembly 15 while bead-shoulder-forming means 65 are maintained in their bead-shoulder-forming positions to restrain axial movement of the tyre bead regions towards each other. Then the bags 80 of means 65 are deflated to allow the tyre bead regions to move axially towards one another while the assembly 15 continues to move radially outwardly to form the tyre carcass material 175 into substantially torus configuration. This method of building pneumatic tyres may be carried out using a tyre building drum described in Specification 1,253,869.

Abstract: 541,748. Carding-engines; treating fibrous webs. VARGA, A. April 8, 1940, No. 6302. [Classes 120 (i) and 120 (iii)] [Also in Group XXXV] The fibrous web produced on a carding engine is submitted to a moist vapour or steam treatment which renders the surrounding air capable of forming a continuous conductive path between the web and a convenient earthing means so that static electricity is discharged from or about the web and its spinning properties increased; the web may be passed between a pair of rollers or cylinders which crush impurities in the web. As shown the web 2, after passage through the rollers or cylinders 22, 23 which crush the impurities in the web, passes between rollers 3, 4 geared together and supplied through pipes 5 and hollow stub axles 7 with moist steam; the rollers are lightly pressed together by springs or the pressure may be sufficient to cause the crushing of the impurities in the web. The web is delivered over a roller 16 driven from the roller 4 and carried in a pivoted bracket so that it may be adjusted relative to the roller 4. The lower heated roller 4 is disposed in a water trough 24 so that steam is released to moisten the web and create a conductive path from the rollers, or steam pipe or both to earth; a shield 25 concentrates the vapour before the rollers and the roller 16 may be cleaned by an adjustable device 26. The web may be dried before passing between the crushing rollers. In another arrangement the web is led around heated rollers to three crushing rollers from which it is carried through a chamber or partly enclosed area by a lattice where moist vapour or steam is released within the websupporting means. Specification 444,043 is referred to.
