IPC: G01N1/18
Filed: 1969-11-03
Abstract: 1286697 Fraction collectors W E GILSON 3 Nov 1969 [12 Nov 1968] 53785/69 Heading B1X [Also in Division F2] An interconnected series of containers 26 for collecting fractions from a filling assembly 36 are mounted spirally on a freely rotatable table 24 and individual containers are sequentially aligned with the filling assembly by a tooth 50 on the assembly which moves in a closed path and has surfaces which engage the wall of a container in the manner of a cam to incrementally rotate the table and cause the filling assembly to slide along an arm 40 attached to a drive leg 42 towards the centre of the table. The containers 26 are supported on the table 24 in a tray 28 which is frictionally held on the table and includes a hub 28a and a flange 28b. Lugs 30, 32 interconnected by a spring 34 fix the series in place on the tray 28. The drive leg 42 transmits motion to the tooth 50 and is reciprocated vertically and oscillates about its end remote from the arm 40 by the action of a system of levers (72), (86), Figs. 5-9 (not shown), which engage a shaft (43) fast with the leg and are actuated by cams (80), (90) rotated by a motor (84). A filling tube 52 of the assembly 36 is secured to an L-shaped support member (106), Fig. 11 (not shown), which is pivoted at (108) and maintains the tube in a container-filling position by the engagement of a pin (116) in an aperture (118a) in a spring latch (118). A stop 120 which is placed in the container following the container at which it is desired to terminate the filling operation engages the latch (118) to release the member (106) which is pivoted by a spring (124) to move the tube 52 to a position over a drainage trough 126. The filling operation for each container is controlled by an electronic drop counter, an adjustable timer or a volume measuring or sensing device.
Patent GB-540319-A (GB)
Abstract: 540,319. Calculating- apparatus. BALL, W., KEEN, G. P., and BRITISH ADDING & CALCULATING MACHINES, Ltd. April 29, 1939, No. 7765/40. Divided out of 540,283. [Class 106 (i)] In a machine wherein the transfer movement is effected by imparting an additional movement to the differential actuator rack the said rack is restored to normal position by the operating mechanism during the same cycle of operation after the totalizer wheels have been disengaged. The invention is shown applied to a machine with a differential rack mechanism as described in Specification 540,283. This mechanism comprises totalizer engaging racks 12 each of which has an extension carrying a pinion 15 engaging corresponding racks 13, 14. The rack 14 is normally fixed but can be conditioned for a step movement by a transfer member or bell crank 106 actuated by a totalizer wheel or lower denomination to free the rack as described in the above mentioned Specification. Each rack 13 carries an abutment plate 22 with a pin engaging an inclined slot in the extension of the rack 12. Reciprocating motion is imparted to each set of racks by a link 32 attached to the corresponding pinion 15 and having a slotted or lost motion connection with a spring controlled bell crank lever 35 operated by a corresponding cam 42 on the main shaft 43. The cams 42 are formed with depressions 237. During the clockwise rotation of the cams the racks 12 are set differentially after which the totalizer pinions are engaged through the intermediate pinions 49. During the return stroke the cams again pick up the bell cranks 35 to enter the setting on the totalizer pinions after which the pinions 49 are disengaged. Near the end of this movement a projection 110 on each rack 12 releases a latch 109 to free the racks 14. If a transfer position is reached the bell crank 106 is conditioned to permit the rack 14 to undergo a step of movement. The roller 41 on the appropriate bell crank 35 thereupon enters the depression 237 and causes the rack 14 to return to neutral position. Specifications 263,505, 288,672, [both in Class 106 (i)], 343,448, 343,473, 343,474, 343,475, 343,476, 352,958, 540,315 and 540,320 also are referred to.

Abstract: 1360469 Detecting power cable faults BOWDEN BROS Ltd 4 Dec 1972 [2 Dec 1971]  56017/71 Headings G1N and G1U Faults in an overhead power line are detected by sensing any significant change in the ground level magnetic field. Fig. 1 shows the system in outline; a ferrite cored winding 1 responds to changes in the field, and its signal is amplified at 2 and fed via a sensitivity potentiometer 3 to a bi-stable switch 4. When a test switch 8 is manually pressed, either a green or a red light is illuminated depending on the state of the bistable switch. A further manual switch 9 allows the red light to be tested. In use the system is placed on the ground when the power line is functioning normally; if switch 8 is pressed the green light operates. If there is a subsequent field change of magnitude sufficient to operate the bi-stable switch, the red light will operate when switch 8 is pressed. The bi-stable switch may be a flip-flop, Fig. 3 (not shown) or an SCR Fig. 4 (not shown). A delay is preferably built into the system to avoid switching by transients. The bi-stable switch may be automatically reset when the original field is restored by correcting the fault.

Abstract: 1,244,897. Controlling clutches. DOMINION ENG. WORKS Ltd. 1 Dec., 1969 [23 Dec., 1968], No. 58611/69. Heading F2L. Load sharing between, and prevention of overload of, two A.C. electric induction motors 17, 19 driving a common output member 11, e.g. in a grinding mill, through air controlled clutches 18, 181, is achieved during start up by starting the motors unloaded and then engaging the clutches and controlling their slip in accordance with the individual motor loadings to limit these loadings to a predetermined percentage, e.g. 175%, of normal full load. The clutches are controlled by controllers 24 which as shown receive amplified signals from electrical load sensors 30 in the motor stator inputs. Again, torque sensors may be attached to the motor stator, or the output shafts to the pinions 12, 13 driving the member 11. Alternatively, temperature sensing means may be utilized on the motor rotor. When the mill speed reaches that of the motors, i.e. clutch slippage ceases, the motor torque decreases to its full load value and the motor and mill accelerate together to their full load speed.

Abstract: 1,187,709. Control of A.C. motors. ROBERT BOSCH G.m.b.H. 19 Dec., 1968 [20 Dec., 1967], No. 60500/68. Heading H2J. [Also in Division G3] In a system for controlling the slip frequency of an asynchronous machine 20 which is supplied at controlled frequency from a source 27 adapted to receive regenerated power, the stator 21 is connected to inverter 22 associated with generator 28 whereby the motor voltage increases with frequency to maintain constant flux. The control generator 28 is connected to oscillator 31 producing a wave whose frequency is proportional to the voltage derived from an integrator 32 associated with a digital-analogue converter 33. The latter is connected with a bidirectional counter 34 whose input r receives pulses from the oscillator 31, whilst input v is fed from summer 35. The output slip frequency signal from oscillator 38 is applied to the input 36 of the summer 35, this signal being determined by the setting of an accelerator pedal 39 or the output of a comparator 42 forming part of a speed-regulating system. A signal from tachometer generator 24 is fed to the input 37 of adder 35. If the motor speed exceeds a predetermined value, an increased rate of pulses is fed to input v of the counter 34, exceeding the rate fed to the input r, whereby the frequency of the oscillator 31 is increased until a new steady state is obtained and the counter 34 returns to zero output. When the machine 20 operates as a generator, the inputs to the summer 35 are changed over. The bi-directional counter comprises counting stage 46 (Fig. 2) receiving signals V, R, from stage 49 to decide the direction of counting in dependence upon the state of flip-flop 47. When stage 46 reaches its maximum count, this information is fed to stage 49 whereby the counter is influenced only by pulses which reduce its number. A coincidence gate 50 eliminates simultaneous pulses tending to move the counter in opposite directions. An adder stage 56 receives a constant frequency signal from oscillator, 64 which determines the transition from motor to generator operation, as well as the signal from generator 24. Adder stage 55 receives a feedback signal from oscillator 31 and the slip reference signal from oscillator 61.
