Abstract: 983,750. Indicating clogging of filters. V. D. ROOSA. Oct. 30, 1961 [Oct. 31, 1960], No. 38775/61. Heading B1D. [Also in Division F1] Clogging of a fuel filter 12 in the inlet pipe 18 of a fuel injection pump 22 is indicated by a pressure-sensitive switch 30 which, when operated by a drop in pressure in the pipe 18 occasioned by clogging of the filter, actuates a signal means. The switch 30 is formed as an end cap for the housing of the supply and injection pumps 21, 22, and includes a diaphragm 46 normally urged to close contacts 49, 60 by a spring 50 in a recess 32 connected to the inlet passage 26 by a port 78. In Fig. 3 the contacts 49, 60, are in series with a coil 86 which, when energized by closing of the ignition switch 84, breaks a switch 91 in the circuit of a signal lamp 90. Clogging of the filter causes breaking of the contacts 49, 60, to de-energize coil 86, causing lamp 90 to light. In a modification the indicator 90 is normally lit and is put out of operation to indicate filter clogging. In Fig. 5 the contacts 49, 60 are in series with a normally energized solenoid 82 which holds a stop valve open in the fuel delivery line. Breaking of the contacts 49, 60 upon clogging of the filter de-energizes coil 82 and cuts off the fuel supply temporarily, whereupon engine speed decreases and, due to a pressure rise in pipe 18 the contacts 49, 60, reclose to reopen the feed supply so that the cycle is repeated and the clogging is indicated by intermittent engine operation. Specifications 647,707 and 656,906 are referred to.

Title: Process and device for burning fuel in furnaces
IPC: F23C9/00
Filed: 1929-12-20
Abstract: 347,174. Preheating and igniting fuel in furnaces. STOCKHOLMS AKTIEBOLAGET PRIVAT, 18, Regeringsgatan, Stockholm. Dec. 20, 1929, No. 39079. Convention date, Jan. 17. [Class 51 (i).] In furnaces in which the fuel has a progressive movement upon or over grates, particles of incandescent fuel or fuel residues are blown up through the front portion of the grate for igniting the fuel supplied by a hopper. Where the fuel is preheated or dried in a hopper, this may also be effected. by the incandescent particles. In the furnace shown in Fig. 1 having a travelling grate 7, a fan 6 draws incandescent particles with hot air and gases from the rear of the combustion chamber through a perforated channel 4 and delivers them through a pipe 7 to a spiral. housing 8 from which they are supplied through the front portion of the grate into the fuel layer supplied by the hopper 3. A preheating hopper 2 may be provided into which hot air and gases may be delivered in any known way. In the modification shown in Fig. 3, incandescent particles and gases are withdrawn from the rear of the furnace by a fan 6 through a pipe 4a, having an air inlet at 10; and delivered through pipes 7, 7a below the front portion of the grate and to the fuel hopper respectively. A fan 12 exhausts gases containing water vapour from the front part of the furnace through a pipe 16, having an air inlet connection at 15 and a connection 11 with the fuel hopper and delivers them through channels 13, 14 to the centre and rear of the grate. The invention is also described and shown as applied to a stationary inclined grate, the incandescent particles being withdrawn from various parts of the furnace flues, and as applied to an underfed grate in which the fuel is delivered to the centre of the grate by a screw and is then fed over lateral grates.

Title: Method and apparatus for regulating simultaneously the feed of an engine operated with heavy oil gas and of an associated oil gas generator
IPC: F02M21/00
Filed: 1930-12-31
Abstract: 368,887. Vaporizers. CHILOWSKY, C., 15, Rue du Lunain, Paris. Dec. 31, 1930, No. 39306. Convention date, Jan. 3. [Classes 7 (iii) and 7 (vi).] In an oil-gas generator of the type in which gasification of the heavy oil is effected by partial combustion of the oil in a charge of compressed air, the admission of air to the compressor is controlled by a pressure-sensitive member which depends for its movement on the difference between the air pressure at the compressor inlet and the gas admission pressure. An air-controlling member 1, Fig. 1, movable in a cylinder 2 having air admission ports 6, is subjected on its top face to the pressure existing in a collector through which the gases pass from the generator to an engine, whilst the lower face is subjected to the suction pressure of the compressor 10. Non-return valves 12, 13 are located in the compressor inlet and outlet pipes 9, 14 respectively. In a modified arrangement, Fig. 3, the proportion of air to the quantity of gas produced may be controlled, without interfering with the automaticity of the apparatus, by means of an additional calibrated air-admission orifice 19 which ensures a proportionately increased output from the compressor at low engine speeds. The output of the compressor may be normally greater than is required by the engine, in which case a controlled byepass 15 may connect the outlet with the suction side of the compressor, the outlet 16 from the byepass being regulated automatically in accordance with the position of the moving member 1 by an obturating device 18 attached thereto. The Specification as open to inspection under Sect. 91 (3) (a) describes an arrangement in which a moving member 1, Fig. 4 (Cancelled), controls the admission of oil gas to an engine manifold ; the suction pipe 24 of the compressor 25 is connected to the space above the member 1 whilst the space below communicates tnrough a pipe 21 with the engine manifold 22, to which the gas from the generator is admitted from a collector 20 through controlled ports 6. This subject-matter does not appear in the Specification as accepted.

Title: Nuclear reactor fuel assembly
IPC: G21C3/322
Filed: 1970-08-14
Abstract: 1318303 Fuel elements GENERAL ELECTRIC CO 14 Aug 1970 [15 Aug 1969] 39420/70 Heading G6C A fuel assembly comprises a plurality of fuel rods in spaced array between tie plates, an openended tubular flow channel surrounding the array, a leakage control member positioned between one of the tie plates and the flow channel for controlling or preventing leakage of coolant, and a coolant by-pass flow passage formed in the assembly and providing a by-pass flow of coolant from the interior to the exterior of the assembly. In one embodiment (Fig. 5), the control member is a resilient bellows 58 secured at its lower end by rivets 59 to the lower tie plate 27 and extending upward to engage at its upper end the lower edge of the flow channel 36. It is not necessary for the bellows 58 to extend around the corners 49 of the tie plate 27 since the flow channel 36 bears tightly against these corners and an increase in pressure within the channel tends to circularize the channel with a resultant even tighter fit against the corners 49. By-pass flow passages 50 through the lower nose piece portion of the tie plate 27 and/or bypass flow passages 51 through the lower portion of the flow channel 36 provide the desired bypass flow of the coolant between adjacent fuel assemblies. In another embodiment (Fig. 4, not shown), the leakage control member is a resilient split ring retained in a circumferential groove in the lower tie plate, which ring provides an outward bias against the lower inner surface of the flow channel sufficient to compensate for the maximum anticipated expansion of the flow channel due to changes in pressure. In a further embodiment (Fig. 6, not shown), the leakage control member is a radially extending flange formed on or secured to the lower tie plate between the latter and the flow channel. The lateral thickness of the flange is sufficient to provide an interference fit with the flow channel sufficient to preload the flow channel to the expected maximum deflection.

A device for the protection of electrical apparatus against excess voltage appearing on a line L, comprises a transformer T2 connecting the apparatus with the line, two oppositelypoled rectifiers D1, D2 connected in series across a winding of the transformer and a direct current source B connected between the junction of the rectifiers and a tap on the transformer winding to back-bias said rectifiers. The invention is applied to a telephone subset in which the apparatus to be protected is a push-pull transistor amplifier TS1, TS2 connected over transformer T1 to the microphone. The transformer T2 is a hybrid serving to connect the microphone amplifier and the loud-speaker amplifier H to line. When a surge occurring in line L exceeds the bias voltage, then according to the polarity of the surge one of the diodes, say D1, conducts to protect TS1. The consequent loading is also reflected, by the transformer T2, across the transistor TS2 which is thereby also protected. The battery B serves also to provide biasing potential for the transistors and has a voltage equal or less than half the maximum voltage which can be tolerated by the transistors.
