Title: Automatic weighing machines
IPC: G01G13/295
Filed: 1974-06-18
Abstract: 1499502 Automatic feed weigher TOOTAL Ltd 18 June 1975 [18 June 1974] 26862/74 Heading G1 [Also in Division G3] A weighing system is controlled by a program, e.g. for dispensing non gaseous dye colouring fluid for textile printing at a number of different stations in accordance with the program. A fluid dispensing valve lies at each station and comprises a fluid inlet 6 and an outlet 10. The latter is closed by member 16, which can be set to flood, drip, dribble and off flow-rates by pneumatic pressure acting against spring 38. A liquid container is mounted on a self powered trolley movable on tracks between the stations and a weighing device, e.g. three load cells, finds the weight of the container plus its contents. The weight is compared with a program target level for that station to give an error signal for controlling the valve at that station. A dynamic detector Fig. 5 (not shown) responds to the error and its rate of change and the valve is turned off in advance of the error reducing to zero. The program instructions are provided on punched cards or tape to give the appropriate colour mix, a printer gives the weight added at any particular station, and the trolley position is monitored using magnets placed alongside the track.

Title: Improvements in and relating to the fermentation of waste organic material for agricultural purposes
IPC: C05F17/00
Filed: 1960-08-05
Abstract: Compost is obtained by placing waste organic material together with a minor proportion of compost from a previous fermentation in an open-topped vat of which the side walls are formed to allow abundant natural aeration of the material, spraying with an aqueous solution of a nitrogenous compound to bring the water content of the mixture to 50 to 60% and the carbon to nitrogen ratio to 25 to 35:1. The vat preferably has a volume of less than 100 cubic metres and less than 85 cubic metres of household waste is placed in it. In a preferred plant refuse is unloaded by gravity from vehicles on a platform 4 into a vat 1 and about 20% of its weight of compost from previous fermentations added and also up to 30% of sewage sludge.

A received wave with horizontal polarization E 2  may be separated by a wire reflector 15 from a transmitted wave with vertical polarization E 1 . The plate 10 and reflector 11 may be replaced by a parabolic reflector 14, Fig. 8. Small side lobes are obtained by using a large diameter beamwaveguide which may be coupled to a smaller guide by a lens which images the last phase plate of one guide into the first of the next guide. The larger guide may consist of a single plate 17, Fig. 11.

Abstract: 1451171 Borehole logging TEXACO DEVELOPMENT CORP 20 June 1974 27328/74 Heading G1A Washout conditions behind the casing in a cased well borehole are detected using a neutron logging apparatus. Apparatus similar to that described in U.K. Specification 1364575, which operates by irradiating the formation with rapid bursts of high energy neutrons, is used. The detector output is gated during neutron bursts to obtain signals representing gamma radiation due to miladic scattering and for shorter intervals just before the neutron bursts, to detect the background gamma due to lingering thermal neutron populations. The signals representing the elements carbon, oxygen, silicon and calcium as provided by pulse height analyzer 24 and the background signals in the corresponding analyzer windows, are fed to computers 25, 26 to obtain background corrected ratios for C/O and Si/Ca. These are recorded with C, O, Si and Ca values at 30. The total count for these elements provides a hydrogen index which is indicative of washout conditions, Fig. 3. When the C/O and Si/Ca ratio amplitudes for washout zones are compared with calibration curves, the depth (and volume) of the washed out material may be obtained.

Abstract: 519,585. Inductor alternators ; switching systems for consumption apparatus; charging batteries. WESTINGHOUSE ELECTRIC & MANUFACTURING CO. Sept 23, 1938, No. 27727. Convention date, Sept. 30, 1937. [Classes 35 and 38 (iv) ] A polyphase inductor generator, particularly applicable to motor vehicle battery charging, comprises a relatively large toothed inductor rotor and a single small toothed salient stator member spanning a portion of the rotor periphery and mounted on a casing which encloses the rotor, the stator tooth pitch being less than that of the rotor and carrying polyphase windings in. which high frequency voltage is generated. In the form shown rotor laminae 56 with rounded teeth 58 are secured to the flywheel of a vehicle engine and co-operate with the salient pole member 52 disposed in a recess formed in the clutch and flywheel casing 48. A three-phase winding is disposed in the stator slots which preferably are so narrow as to accommodate a single row of conductors 61 only. The end stator teeth are cut back in a straight line, as at 83, to give a tapering airgap. The rotor teeth pitch is preferably 2N times the states pitch where N is the number of phases. Windings illustrated show (1) a double star full pitch winding with four turns in series under each rotor pole so arranged that one circuit in the two parallelled windings contains conductors in two top and two bottom layers while the other circuit contains the conductors in the four intermediate layers of the six conductors per slot and (2) a straight delta winding with six turns in series for each of the six rotor poles spanned by the stator. Fig. 3 shows the connections of a double - star stator winding A, B, C in a motor-vehicle system for battery-charging through a double star-connected full wave rectifier 63. The battery 76 floats on the continuous-current lines 70 and the alternator field 54 is connected directly across the rectifier output leads which are connected to the lines 70 through a reverse current switch 72 provided with shunt and series coils 73, 74 and arranged to be open when the alternator is at rest. When the engine starts, the alternator open - circuit voltage, when rectified, slightly exceeds that of the battery and causes the coil 74 to close the switch, and allow the series coil 73 to reinforce the effect of the other coil. On deceleration, when the rectified alternator voltage falls below that of the battery, a momentary field current from the battery in the series coil 74 opposes the shunt coil magnetically and the switch 72 opens. Alternating current is also taken off at 68.
