Title: Improvements in or relating to jigs for washing coal, ore, and the like
IPC: B03B5/24
Filed: 1946-07-25
Abstract: 645,823. Washing granular materials. PREPARATION INDUSTRIELLE DES COMBUSTIBLES, July 25, 1946, No. 22184. Convention date, July 6, 1945. [Class 82(ii)] [Also in Group XXIX] In a device for automattically controlling the discharge from coarse grain, fine grain or filter bed washing jigs for coal; ore &c. the movement of the control members, e.g., an air cock and/or flaps or gates, is dependent on the movement of a float to each position or to the-highest position of which there corresponds one position of the control members, the latter being operated by a hydraulic servomotor having a double-acting piston. A piston reciprocates water in the jig causing the water to pass through a washing bed to discharge the heavy products. When a float 9, Fig. 2 detects a decrease in the thickness of the layer of heavy products to be discharged, it operates a servo-motor 22 to open a valve 8 of an air chamber 7 connected between the reciprocating piston and the bed so that reciprocation of water through the bed is reduced. The float moves a screen 20 over a wall of the servocylinder containing ducts 23 into which pressure liquid is directed from nozzles 24. At rest the servo-piston 21 lies opposite the screen, but when the screen moves the ducts carried by it exhaust pressure liquid from one side of the cylinder so that the piston follows the movement of the screen and adjusts the valve. In the modification shown in Fig. 7, the float 47 oscillates up and down with the reciprocation of the water through the bed and carries an abutment 52 on the float stem 49 which, at its highest point, contacts a lever 55 of a lever system for moving a sector 60 over the ported wall of 'the servo-cylinder supplied at both ends .31, 32, with pressure liquid. At rest the servo-piston lies opposite an exhaust connection 30 in the sector and when the sector moves the piston follows the movement of the exhaust connection to adjust the valve. The lever 55 is connected to a piston 57 having a check valve 62 which retards the downward movement of the lever but not its upward movement. In another embodiment, the ducts contain spring-loaded ball valves which are opened by a cam replacing the screen or sector. In a further embodiment, a coarse grain jig has discharge gates and flaps which are-operated by the servo-motor controlling the air valve.

Title: Improvements in the control of hydraulic power steering mechanisms at extreme steering positions
IPC: B62D12/00
Filed: 1968-05-10
Abstract: 1,221,082. Steering articulated vehicles. EATON YALE & TOWNE Inc. 10 May, 1968 [23 May, 1967], No. 22235/68. Heading B7H. In hydraulic steering mechanism for an articulated vehicle having a pair of steering rams 20 (only one shown) connected between relatively rotatable frame sections and supplied with pressure fluid from a control valve 13 actuated by a steering wheel 15 through a pitman arm 14 and linkage 16, 17, 19, there are provided piston devices 23, 24 which are arranged to co-operate with the pitman arm 14 as it approaches either extreme position and are connected to the pressure supply to the valve 13 so that the pitman arm 14 is forced away from an extreme position should the supply pressure rise due to retention of the steering wheel at full lock when the frame sections have reached the limit of their permitted relative rotation. Each piston device 23, 24 includes a piston 27 which carries an adjusting screw for engagement with the pitman arm 14 and is subjected through a line 30 to the pressure in a supply line 33 between a pump P and the control valve 13. A relief valve 34 discharges fluid into a return line 35 to a reservoir R if the supply pressure exceeds a predetermined maximum. The pitman arm 14 is mounted on one frame section, the valve 13 on the other section, and one element 17 of the linkage pivots on the axis 18 about which the sections are connected to provide a follow-up action. As the operator turns the steering wheel 15 and the pitman arm 14 approaches an extreme position, the arm depresses one of the pistons 27 against the pressure existing in the supply line 33 and the operator senses that the extreme position is approaching. When the frame sections reach their limit position, the supply line pressure increases and, unless a considerable force is exerted on the steering wheel, the piston 27 moves the arm 14 from the extreme position to prevent the valve 13 further supplying the rams 20.

Title: Improvements relating to space and water heating systems
IPC: F24F3/00
Filed: 1961-06-22
Abstract: 942,688. Heat pumps; refrigerating; hotwater supply systems; air conditioning. B. R. LEIGH. June 22, 1962 [June 22, 1961], No. 22639/61. Headings F4A, F4H and F4V. A heat pump includes first and second heat exchangers which respectively heat air for space heating and water for a hot-water system. As shown in Fig. 1, the first heat exchanger 3 is located in a duct 11 through which air is circulated by a fan 12 when space heating is required and the second heat exchanger 4 is located in an auxiliary water tank 14 which is connected to a hot-water storage tank 16 by flow and return lines 17, 15. A water circulating pump 18 is included in line 17 and the tank may be provided with supplementary heating means, e.g. an immersion heater, and baffles for reducing convection circulation therein. The evaporator 6 of the heat pump is utilized when space cooling is required and is defrosted by anti-freeze liquid dripped over it from a device 9. The defrosting is initiated and the heat pump compressor 2 stopped by switch means 8 in the suction line when the pressure therein rises above a predetermined value. Switches 20 on the high pressure side of the compressor have contacts in a control circuit (Fig. 4, not shown) which are arranged to control the water pump 18, the compressor 2 and a fan 29 in dependence on the refrigerant pressure at the compressor outlet and hence on the temperature of the water in tank 14. Thermostatic control of fan 12 is also provided. As shown in Fig. 2 the evaporator 6 is located in a duct 26 and the heat exchanger 3 in an aperture between a duct 38 and a chamber 36. When space heating is required the fan 12 draws filtered air from the interior of the building through an opening 37, chamber 36, exchanger 3 and a duct 41 which communicates with the exchanger 3 through an aperture 42, the heated air being supplied to the building through an outlet 13. The fan 29 is located in a duct 28 and blows air over the evaporator and through adjustable louvres 24 to atmosphere. When cooling is required flap valves 32 and 33 are raised (Fig. 3, not shown) separating ducts 26 and 28 and establishing communication between ducts 26 and 41 and between ducts 28 and 38. The aperture 42 in duct 41 is closed and the fan 12 now draws air from the exterior of the building through louvres 24, evaporator 6 and duct 41 while fan 29 blows air over heat exchanger 3 when the water in tank 14 is sufficiently hot to dissipate heat therefrom to atmosphere through a window 39. A window 31 in the duct 26 may be opened to allow air to be recirculated from the interior of the building to the evaporator.

Title: Signal control circuit
IPC: G11B20/04
Filed: 1973-05-11
Abstract: 1412702 Compounders SONY CORP 11 May 1973 [13 May 1972] 22702/73 Heading H4R In a rectifying circuit, particularly for providing the control signal for a compressor or expander in a magnetic recording system, a rectifier rectifies an incoming signal to produce a control signal and a circuit connects rapidly changing portions of either polarity of the input signal to the control signal output in the appropriate polarity to reinforce the control signal. As described a control signal for a variable impedance formed by transistor 36 in a variable filter 32 to 34, is derived from the filter output by the control circuit 18 the last stage of which provides three outputs to the rectifier circuit 18<1>. Under steady state conditions a high value capacitor 63 feeds the signal to rectifier 64 to provide a D.C. control signal across capacitor 67. When a negative going transient appears at the base of transistor 56 a corresponding positive signal at the collector of transistor 56 causes a positive potential to be applied across resistor 65, adding to the signal across capacitor 67 for application to the variable impedance circuit. When a positive potential is applied to the base of transistor 56 the resulting negative potential at its collector does not appear across resistor 65 because of conduction of diode 60, however the positive potential across the lower part 62 of the emitter load of transistor 56 is transmitted by capacitance 67 to appear at the control output, in addition to the normal voltage on capacitor 67. The control voltage varies the cut-off frequency of the high pass filter 17 which is connected either in the forward path relative amplifier 12, to provide high frequency pre-emphasis to a recording head during recording, or in the feedback path of amplifier 12, to provide deemphasis, on playback.

Title: Production and separation of fibres from bast fibre plants
Inventor: VONDERS KAREL HENDRIK
IPC: D01B1/20
Filed: 1950-09-15
Abstract: 691,751. Preparing fibres for spinning. ZEGERS, W. F. H. Sept. 15, 1950, No. 22751/50. Class 120(i) In a process for removing woody materials from fibres in the stems of plants, the stems are simultaneously clamper at at least two different spaced points along the stems and the parts of the stems between the clamping points are jerked and stretched in rapid repetition. As shown, Fig. 1, plant stems are laid on feed table 1, and their root ends are pulverized by a vertically-reciprocating ribbed plate. The stems are gripped between a lower endless belt 2 and an upper co-operating belt 2<SP>1</SP> and carried forward, the root ends being bent downwards by an oscillating paddle 5 so as to pass between mechanism for splitting the stems longitudinally and bending them transversely. This splitting and bending mechanism comprises vertically travelling endless chains 7 carrying co-operating rollers 8, 8a, Fig. 9, between which the stems are rolled, first loosely at 14 then tightly at 15. Further bending mechanism comprises blocks 13, 13<SP>1</SP>, Fig. 10, carried on chains 7 or adjacent chains, between the S-shaped faces of which the stems are drawn; particles broken from the stems fall through apertures 19, 20 in the blocks to be sucked away in a suitable pipe beneath the bending mechanism. Additional roller sets and/or bending blocks may be used. After bending, the broken and loosened woody parts are removed by passing the stems between three pairs of lath-shaped clamping means 21, 21', a lath 21<SP>1</SP> lying behind each lath 21. Each lath 21 or 21<SP>1</SP> has a resilient toothed jaw 22 or 23, Fig. 5, co-operating with a fixed jaw of the opposing lath. Lath 21<SP>1</SP> is adjustably fixed and lath 21 is vibrated to and from lath 21<SP>1</SP> at the rate of 1000-2000 vibrations per minute. As the jaws meet at longitudinally-spaced points of a stem, and as the resilient jaws yield, the stem is bent between opposing teeth and then jerked and stretched longitudinally between the pairs of jaws. The vibrations set up in the fibres tear loose and discard the previously-broken woody parts. The stretching action progresses along the stem as the latter is fed past each pair of laths. In successive pairs of laths, the jaw teeth become finer, the jaws are spaced further apart, and the stretching action is arranged to increase. After the root ends have been treated they are lifted by a rotating paddle 26 or by a blower, and the stems are gripped at a fresh point between a lower conveyer 27 and a co-operating upper conveyer 27<SP>1</SP> while the tip ends. of the stems are similarly treated. Prior to the mechanical treatment, the stems may be intensively dried and then exposed in a humid atmosphere long enough to moisten the fibres while leaving the woody cores dry.

Abstract: 714,986. Transistor circuits. WESTERN ELECTRIC CO., Inc. Sept. 12, 1952 [Sept. 18, 1951], No. 22945/52. Class 40 (6) A signal translating circuit comprises two transistors, one of N- type material and the other of P-type material having two like electrodes (e.g. the bases) together, an input signal applied in parallel to a second pair of like electrodes (e.g. the emitters) and an output signal taken in parallel from the third pair of electrodes (e.g. the collectors). This circuit gives a push-pull type of operation in that second-order effects resulting in the generation of even order harmonics are suppressed; however balanced input and output circuits are not required. Fig. 1 shows an amplifier comprising a P-type transistor 1 and a N-type transistor 2 fed from constant current sources 3 and 4. An unbalanced input signal is applied to the emitters from the signal source 5 and the output is taken from across the load resistor 8. A closely coupled transformer 11 having unity turns ratio ensures that the signal currents in the two col!ector-base circuits shall be of equal amplitude and of opposite sign with respect to the mean collector currents. In Fig. 3 (not shown) is illustrated a similar amplifier employing constant-voltage sources instead of the constant-current sources shown in Fig. 1. It is stated that the circuit may also be employed in connection with a modulator detector or oscillator.
