IPC: G01G13/00
Filed: 1956-07-27
Abstract: 832,354. Automatic feed weighers. NORTH THAMES GAS BOARD. Oct. 25, 1957 [July 27, 1956], No. 23330/56. Class 143 An automatic feed weigher is provided with a temporarily acting weight 13 which is lifted from the beam 5 by a solenoid 16 at the same instant as the bulk feed 22 is stopped. When the beam moves downwardly under the combined weight of the pan and weight 13 it operates a pair of switches 17, 18 which respectively stop the bulk feeder 22 and energize solenoid 16; the beam being prevented from operating further switches 19, 20 at this stage by a lever 11 which is locked by a member 15 on the weight raising rod 14. When the beam moves down for the second time under the weight of the pan 6 only, lever 11 is free, and thus the abutment 10 operates switches 19, 20 which respectively cut off the dribble feeder 23 and unlock the pan door 7 ready for subsequent manual opening. Specification 329,563 is referred to.

Abstract: 896,612. Tell-tale cameras. BERNING, H. H., [trading as ROBOT BERNING UND CO.]. July 22. 1958 [Aug. 2, 1957], No. 23425/58. Class 98(1). The approximate speed of a motor vehicle is recorded by photographing the vehicle as it enters and leaves marked sections of the road by means of two electrically operated cameras. The two exposures are separated by a fixed time interval. As shown, a light beam 8 is interrupted by the vehicle so as to operate camera 5 and start time delay relay 7 as the vehicle crosses line 2. The position of the vehicle in relation to the lines 3, 4, 4<SP>1</SP> and 4<SP>11</SP> is recorded by camera 6 after the time interval has elapsed and provides an approximate measure of the vehicle speed. The date or time may also be recorded on the photograph taken by camera 6. Advantageously, a switch is provided to render the cameras inoperable when a vehicle is approaching at too slow a speed. The film may be changed automatically after each exposure and the cameras may have interchangeable lenses. Light beam 8 may be replaced by pressure operated contacts. Electrical circuits are described in out-line.

Title: Improvements relating to pneumatic thread holders for weft replenishing looms
IPC: D03D45/50
Filed: 1938-08-09
Abstract: 511,721. Looms with automatic weft replenishment. CROMPTON & KNOWLES LOOM WORKS. Aug. 9, 1938, No. 23442. Convention date, March 31. [Class 142 (iii)] As shown diagrammatically in Fig. 10, the weft ends from the reserve bobbins. B, Fig. 3, extend through a tube 67 into an accumulator C, where they are entangled in a mass T. After a bobbin has-been transferred and its weft end cut, the latter is drawn into the accumulator, which communicates with a tube 35 leading to a pump having a piston reciprocated by connections with the lay. As this moves rearwardly a partial vacuum is thus produced. The cut weft ends from the ejected bobbins are also drawn by an extractor E through a tube 44 into the accumulator C, a baffle plate extending between the inlets of the two tubes. Rotation of the mass of thread in the accumulator is prevented by a fixed bent member 107. The accumulator comprises a transparent hollow cylinder 48 fitting snugly in a base 47 on an arm in a loom side stand. The tube 35 is connected to a hinged cover 59, which is normally held closed by a spring-controlled hooked part 54. As shown in Fig. 6., the base 47 has a bore 65 with a rear curved part fitted with the rubber tube 67, which provides frictional resistance to threads, and is represented only diagrammatically in Fig. 10. The front part of the bore receives a metal tube 70 projecting into a guide member 72, having a bore 81 receiving a second tube 80. This is plugged at 84 and is rotatable by a handle 83 between two extreme positions shown respectively in Figs. 8 and 9, a thread inlet port 82 in the tube 80 always communicating with a vertical slot 85 in the member 72. When the magazine is first supplied with reserve bobbins, the handle 83 is operated to turn the tube into the position shown in Fig. 9, and the weft ends are placed between guiding horns 87 and across the port 82. When the lay first moves backwards, the weft ends are sucked into the tube 80 and directed to its centre by a block 95. The handle 83 and tube are thereafter allowed to move by gravity to their normal position Fig. 8 with the port 82 facing the magazine. The extractor head is carried on a rod, which may be raised and lowered and is controlled by the transfer mechanism. The magazine may be rocked about its pivot in unison with the change boxes at the other side of the loom. Specifications 503,063 and 516,950 are referred to.

Title: Printers having a detecting device
IPC: B41J1/20
Filed: 1973-05-16
Abstract: 1432250 Printers COMPAGNIE HONEYWELL BULL 16 May 1973 [25 May 1972] 23443/73 Heading G4H [Also in Division H3] A printer having a movable support equipped with print-type-carrying fingers (e.g. a moving belt, Fig. 1) incorporates means 33, Fig. 4, for detecting when a finger has been deformed or broken off. The position of the fingers 9, 10 ... on the moving belt 1 is determined by counting the number of holes 13, &c. aligned with the fingers, which are detected by an opto-electronic or magnetic sensor C1 with reference to a datum hole 17 detected by a sensor C2. The detection of holes 13, &c. by C1 results in a sync pulse train CS, each pulse of which triggers a monostable 35, Fig. 4, whose output M1 in turn triggers a monostable 36 and causes a trailing-edge detector 37 to set a flip-flop 38; this is reset in turn by a pulse CD from a third sensor C3 which detects the passage of a finger. The outputs F (O-level pulses T F ) and B (variable-length pulses) from 36, 38 are fed to a comparator 39. Figs. 5 (c), 5(d) show in turn the cases of an undamaged finger (B wholly within T F ), a deformed finger (delayed resetting of 38 results in B extending beyond T F ) and the absence of a finger (no CD pulse, so 38 is not reset). Comparator 39 produces an alarm pulse 34 if BÀF = 1 so that a deformed finger gives rise to a short pulse and a broken finger produces an alarm until the next finger is detected.

Abstract: 1491501 Anaerobic digestion of water polluting waste material BIOMECHANICS Ltd 22 May 1975 [24 May 1974] 23467/74 Heading ClC A method of treating biodegradable waste material by anaerobic digestion comprises the steps of (a) agitating liquid containing waste material within a closed tank and digesting the waste material anaerobically, (b) ceasing agitation of the liquid containing the waste material and allowing solids in the liquid containing waste material to settle for a predetermined period of time, (c) withdrawing from the tank an upper layer of liquid having a solids concentration which is substantially less than the average concentration of the solids in the liquid containing the waste material, and (d) further agitating the liquid containing the waste material within the tank together with a further volume of liquid containing waste material substantially equal in volume to the upper layer of liquid which is withdrawn from the tank. The waste material may be water polluting material. The solids on which the gas bubbles have accumulated may be physically prevented from floating into the upper layer of liquid by a packing material which floats, e.g. plastic Raschig rings, or by a metal grid. Inert particulate material having a density greater than the density of the waste material and a particle size similar to the size of the bacteria (e.g. fly ash or digested sewage) may be added at the digestion stage to assist settling.

Title: Rotary ore-reducing kiln
IPC: C21B13/08
Filed: 1959-07-14
Abstract: 876,211. Rotary furnaces. ROUAUX, M. E. July 14, 1959 [July 24, 1958], No. 24180/59. Class 51 (2). A rotary kiln for the reduction of ore comprises throughout its length a jacket enclosing the treatment chamber and communicating with the interior of the chamber to feed a reducing gas thereto, characterized in that a large proportion of the reducing gas entering the chamber is fed into both ends of the jacket and is injected out of the medial section of the jacket into the corresponding medial section of the chamber to reintroduce the heat removed by the reducing gas off the end walls of the chamber into the medial portion of the chamber. The walls 2, Fig. 1, of the treatment chamber are surrounded by a metal casing 3 forming the annular jacket 4 through which the gas is introduced at both ends through rotary joints 6, 7 and which is injected out of the central portion of the jacket into the corresponding central portion of the chamber via radial compartments 17 and ports 20. The chamber is subdivided into transverse compartments 21, 23, 24, separated by transverse partitions to form lifters to keep the ore, which is preferably in comminuted form, in close contact with the walls of the chamber, and the central compartments 23 are subdivided into the radial compartments 17. Some reducing gas from the joint 7 enter the chamber through channels 8, Fig. 3, controlled by valves 9 and the ports 20 house nozzles 15 controlled by valves 16 to inject oxygen from a plant 10 and distributing pipes 13, 14 into the compartments 17 to burn the gas, which is exhausted through a rotary joint 43 in countercurrent to the flow of ore which is introduced into the treatment chamber from a chamber 26, Fig. 2, which forms a rotary joint 27. After exhaustion through the joint 43 the gas is fed to an arrangement 49 for regeneration and is recycled into the treatment chamber. The ore is removed from the chamber 26 by a worm conveyer 28 having a shaft 29 carried on a bearing 30 and a stuffing box 31 into a chamber 34 having transverse guiding blades 40. The ore passes through compartments 21, 23, 24, the central compartments 23 being formed by annular partitions 18 and having a tuyere fed with reducing gas and oxygen from the nozzles 15, and the metal sponge product formed in the treatment chamber enters an output port 11 to which it is guided by transverse blades 35 in a terminal chamber 36 where it is collected by a worm conveyer 37 for conveyance into a channel 38 connected with a chamber 39 forming a radial joint. The walls of the treatment chamber have helical channels 50 to collect and disperse the ore particles in a continuous manner during rotation of the kiln and the kiln may be subjected to an internal pressure by increasing the pressure of the reducing gas.
