Abstract: 770,474. Animal feeding appliances. WILSON & CO., Ltd., T. J. Oct. 17, 1955 [Oct. 23, 1954], No. 30581/54. Class 5(2). Apparatus for discharging feed stuff into a trough, particularly for use in cow stalls as a means of feeding cows during milking, comprises a hopper 10 mounted on the rails 12 of the stall and having a hinged lid 15, a closure member 18 at its lower end and a hinged horizontal partition 21. The closure member 18 is normally held in its closed position by means of catch members 28 mounted on both ends of a rock shaft 27, one of said catch members being linked through a bell-crank lever 31, a rod 32 and a lever arm 34 to a rock shaft 35 mounted on an overhead pipe 38. A handle is provided for rotating the shaft 35 so as to raise the catch member 28 and release the closure member 18. The partition 21 is held in its horizontal position by means of catch members 23 mounted on a tubular rock shaft 24 (which houses the shaft 27) and protruding through slots in the wall of the hopper. Mounted at each end of the shaft 24 are lever members 26 having flanges 26x and 26y projecting from their top and bottom edges, the catch members 28 being housed between these flanges. The partition may be released from its horizontal position (after the closure member 18 has been released), by further rotating the rock shaft 35 so as to bring the member 28 in contact with the flange 26x thereby rotating the rock shaft 24 and the catch members 23 mounted thereon so as to release the partition. In use, the feed stuff in the lower part of the hopper is discharged into the trough while one cow is in the stall, then the horizontal partition is released so as to discharge the contents in the upper part of the hopper when a second cow is being milked.

Title: Vehicle speed-measuring systems
IPC: G01S15/60
Filed: 1972-06-30
Abstract: 1401364 Pulse radar and sonar systems SIEMENS AG 30 June 1972 [6 July 1971] 30667/72 Heading H4D In a pulse-echo system for determining the speed of a vehicle, echo signals resulting from the transmission of coherent waves are received by a transducer array on the vehicle and are compared with a reference signal in order to record both phase and amplitude information in hologram form, the hologram obtained from one transmitted pulse is cross-correlated with the hologram obtained from the next transmitted pulse, and the speed is determined from the positions of the correlation maxima. The waves may be electromagnetic or acoustic. Figs. 2 and 4 relate to a syntheticaperture side-looking sonar with a row of receiving transducers 4 extending in the heading direction of a ship. Target echo signals are mixed at 5 with a reference signal from transmitter 9 and the mixer outputs modulate a row of light sources 6. These light sources are imaged on to a photographic film 8 which is moved slowly in direction 9 and is moved in direction 10 at constant speed during the propagation of an acoustic pulse. Direction 10 thus represents target range. Direction 9 represents distance along the transducer row. The row of image points, 11, recorded for one particular target range and one particular transmitted pulse, is referred to as a "unidimensional sub-hologram". The record on film 8 thus comprises a respective set of sub-holograms for each transmitted pulse. Cross-correlation of the sub-hologram set for one pulse with the set for the next pulse, to determine the distance moved by the ship between the two pulses, is done by an optical processing system in which a matched filter is derived by recording photographically the Fourier transform of one set, the filter function is correlated with the Fourier transform of the other set, and the resulting correlation function is Fouriertransformed. In various modifications the correlation may be done by electronic computer, only the overlapping subholograms need be correlated, and the holograms and matched filter may be recorded in erasable form by the use of photochromic material or a thermoplastic or liquid-crystal display screen, or a Titus tube. By making the speed of movement of film 8 in direction 9 proportional to the ship's speed, a conventional sonar chart can be obtained from the film by a synthetic-aperture type reconstruction.

Filed: 1966-07-08
Abstract: 1,187,952. Ammonium phosphates. POWERGAS CORP. Ltd. 7 July, 1967 [8 July, 1966], No. 30688/66. Heading C1A. In making a phosphonitrogenous fertilizer, phosphate rock is acidulated with H 2 SO 4  so that a part of the calcium present in the rock is converted to CaSO 4 , the temperature being such as to give a precipitate of gypsum or hemihydrate, this product is then reacted with nitric acid so that substantially all the P 2 O 5  initially present in the rock is converted into H 3 PO 4 , Ca(NO 3 ) 2  also being formed, (NH 4 ) 2 SO 4  is added sufficient to convert the calcium present in solution into CaSO 4 , precipitated as gypsum, the CaSO 4  is removed and the reaction product withdrawn and neutralized with ammonia to convert any free phosphoric acid present into ammonium phosphate. Preferred temperatures for the acidulation with H 2 SO 4  are 60‹ to 90‹ C. or at least 90‹ C. For the addition of (NH 4 ) 2 SO 4  the range 60‹ to 90‹ C. is preferred. In a preferred embodiment the P 2 O 5  in the phosphate rock is converted in part to monocalcium phosphate and part to phosphoric acid during the initial acidulation. A potassium salt or potassium hydroxide may be added to a product solution in which the ammonium phosphate present is monoammonium phosphate to convert some or all of the mono-ammonium phosphate into diammonium phosphate and potassium hydrogen phosphate. The CaSO 4  produced by the acid treatment may be converted to CaCO 3  by reaction with ammonia and carbon dioxide, the (NH 4 ) 2 SO 4  solution produced being used in the process. An example of the process is given using Nauru phosphate rock.

Abstract: 1425966 Measuring rms voltage SOLARTRON ELECTRONIC GROUP Ltd 28 June 1974 [29 June 1973] 31026/73 Heading G1U A circuit for measuring the r.m.s. value of an unknown input voltage 5, Fig. 1, of the type in which the unknown voltage 5 is applied to a first thermal converter 2 and a D.C. voltage is applied to a second identical converter 4, the D.C. voltage being controlled by feedback action 12 so that the output voltages of the thermal converters are maintained substantially equal, is characterized in that a bias signal from an oscillator 34 is also applied to both converters, via coupling capacitors 30, 32, the bias signal being controlled by further feedback 84 so that the total energy supplied to the second converter 4 by the bias oscillator and by the D.C. voltage, is supplied at a substantially constant rate. As a consequence both converters remain at substantially the same absolute temperature, and therefore the circuit responds faster and is more accurate. In the first feedback loop, the output of difference amplifier 12 is applied, via a square-root circuit 17, 20 to the second converter 4 and to an output terminal Vo. The output of difference amplifier 12 (= Vo<SP>2</SP>) is also applied to the second feedback loop via a resistor 98 where it subtracts from a reference voltage VR3 thereby reducing the rate of supply of energy to both converters from the bias oscillator 34 by the amount by which the D.C. voltage supplies energy to the second converter. A suitable construction of a matched pair of thermal converters is outlined Fig. 2, (not shown).

Abstract: 1309767 Welding by fusion ISHIKAWA-JIMA-HARIMA JUKOGYO KK 26 June 1970 [26 June 1969] 31250/70 Heading B3R In flux-submerged arc welding using a consumable electrode 1 placed along the joint but insulated from the workpieces 2, 3, the electrode 1 is held in position by a plurality of spaced holding means which release the electrode successively as the arc advances. The method is applied to seam welding a butt joint (Fig. 4), or a fillet (Fig. 5). The electrode 1, which is a base metal rod, is encompassed by means which space it and insulate it from the workpieces. As shown, the means may be annular spacers 4 of glass, asbestos or rock wool. Alternatively, a continuous helical spacer, or a cylindrical sleeve can be used. The electrode can comprise a number of rods. Each holding means 6 acts also as a current input; a fuse 8, or a trigger wire, arranged in advance of each holding means 6 is activated by proximal arc heat to cause its associated holding means to release from electrode l. Thus the next successive holding means along the electrode 1 assumes the current input function to maintain a continuous arc process. A known submerged-arc flux is used. The electrode and the joint can be curved. Co-pending Application 30742/70 is referred to.

Title: Improvements in or relating to apparatus for testing material by means of pulses of supersonic waves
IPC: G01N29/38
Filed: 1946-10-23
Abstract: 653,380. Supersonic inspection devices. SPERRY PRODUCTS, Inc. Oct. 23, 1946, No. 31466. Convention date, Nov. 14, 1945. [Class 118 (ii)] Relates to pulse echo systems for testing materials for the presence of defects utilizing supersonic energy of the type disclosed in Specification 641,095. When the defect is located at a distance AC, Fig. 2B, from the front surface A of the material which is less than the pulse width AB, the echo pulse CD will overlap the transmitted pulse AB and the receiver output will comprise a single resultant pulse AD, Fig. 2C, so that no clear indication of the defect is obtained and this is overcome according to the present invention by rendering the receiver unresponsive for a short period BE, Fig. 2D, at the terminaation of the transmitted pulse so that the portion ED of the pulse due to an echo may be distinguished. As shown in Fig. 1, an oscillator 30 is pulsed by negative triggering pulses applied to the grid 33 of the normally conductive trigger valve 32 and the output is applied to a piezo-electric crystal 11 in contact with the work-piece 12, the echo pulses being applied together with the output from oscillator 30 via an amplifier 15 to the Y-plates of a cathode-ray tube 16, the X-plates of which are connected to a timebase generator 20 synchronized by the mains supply. The trigger pulses are generated by synchronizing a multivibrator 40 from the time-base generator 20 and differentiating the square wave output by a C-R network to produce positive and negative pulses coincident with the leading and trailing edges of the positive portion of the square wave, the negative pulses being selected and inverted by valve 34 to give positive pulses which are further amplified and inverted by valve 35 to give the triggering pulses, the width of which is controlled by the variable resistance 37 in the differentiating network. In accordance with the invention the grid circuit constants of valve T in amplifier 15 are adjusted so that grid rectification of the pulses from oscillator 30 block the valve for a period after the termination of the pulses which is small compared with the pulse duration. The duration of the time-base is preferably adjusted so that echoes 25<SP>1</SP> from the lower surface S1 of the workpiece 12 are not displayed and in order to prevent display of the transmitted pulse 25, the time-base may be initiated at the termination of the transmitted pulse by synchronizing the time-base generator 20 from the pulse-generator 10 via a multivibrator delay circuit, the multivibrator 40 being free-running in this case, Fig. 4 (not shown).
