Abstract: 835,040. Toothed gearing; linkwork. COLLINS RADIO CO. Dec. 3, 1956 [March 1, 1956], No. 36908/56. Classes 80 (1) and 80 (3). Backlash between gears 20, 21 is taken up by means of permanent magnets 22, 23 secured thereto respectively and arranged so that poles of alternate polarity on one gear come between poles of alternate polarity on the other. One gear is thus always biased in one direction relative to the other and provided that the magnetic force is greater than any peripheral force to be transmitted the play is maintained in one direction. A coupling between a pin 27 on gear 20 and an indicating pointer 25 comprises a magnet rod 26 to which is secured a saddle 30 of-non-magnetic material which embraces with play a magnetic rod 28 carrying the pointer 25. The adjacent ends of the magnets 26, 28 are of opposite polarity so that they are mutually repulsed to take up the play in saddle 30.

Title: Improvements in or relating to a Control System for a Pump Driven by an Electric Motor.
IPC: H02K5/132
Filed: 1967-08-15
Abstract: 1,156,123. Centrifugal pumps. SVENSKA PRECISIONSVERKTYG A. B. Aug.15, 1967 [Aug. 23, 1966], No.37517/67. Heading F1C. [Also in Division G3] Rise of conductive liquid to a predetermined level in an auxiliary chamber communicating with a main chamber is detected by an electrode so that an electric motor-driven pump is started to exhaust the main chamber, the auxiliary chamber having an air outlet above which an air cushion is formed through which the electrode passes. In Fig. 10, when the liquid in auxiliary chamber 13 rises to the level of an electrode 20, a transistor 79 is rendered conductive to energize a relay winding 82 through a rectifier 80 from the secondary of a transformer 68. Relay contacts 83 then start a three-phase extraction pump motor 6. To avoid interruption of the motor circuit due to water disturbance on starting the pump, further relay contacts 84 connect a lower electrode 21 to the control circuit. The two insulated platinum-tipped electrodes are show in Fig. 1 depending from a removeable plastic stopper 17 at the top of the auxiliary chamber 13 which is arranged in the casing containing pump 10 and its driving motor 6. Stopper 17 is rotatable to earth either electrode connection and thus provide manual control of motor 6. Contaminated water to be pumped enters inlets 11 and rises to the electrodes. The pump starts as described above and water is discharged through outlet 5. Pumping pressure influences an acid-proof rubber membrane surrounding a valve 41 so that a vent 40, connecting the upper portion of the chamber 13 to holes 43 in a carrying handle 42, is closed to trap air at 51. Operation of the pump then continues until the level of water has fallen to below the bottom of a tube 15 so that air can enter chamber 13. In a modification, the vent valve is dispensed with and the pump is stopped when the level falls below the bottom of a long electrode provided in chamber 13. Use of delay units instead of auxiliary electrodes to maintain operation of the pump is referred to.

Title: Sheet feed mechanism
IPC: B65H7/12
Filed: 1965-09-02
Abstract: 1,122,625. Feeding sheets. RANK XEROX Ltd. 2 Sept., 1965 [30 Sept., 1964], No. 37590/65. Heading B6B. Sheets which are separated sequentially from the top of a stack by suckers 365 and placed between suction belts 414 and an idler feed roller, are passed through a caliper device which detects the presence of two or more superposed sheets and causes a device to strip the superposed sheets from the belts 414. The belts 414, Figs. 3 and 4 (not shown), have perforations 415 therein and are mounted on a driven roller 417 and an idler roller 420, and a suction chamber 401 is arranged within the belts to co-operate with the lower runs thereof. The caliper device comprises an enlarged central portion 422 on the roller 420, and a roller 439, Figs. 5 and 6 (not shown), on an arm 437 which is pivoted about a shaft 435 supported on a fixed base 436. The roller 439 is urged towards the portion 422 of the roller 420 by a spring 438, and is adjusted relative to the portion 422 by a depending lever 437a on the arm 437 engaging a stop-screw 444 on the base 436. When two superposed sheets pass between the roller 439 and the enlarged portion 422 of the belt roller 420, the roller 439 and arm 437 are rocked to allow an actuator arm 434 on the shaft 435 to close a switch 9LS and thus operate a solenoid SOL-3, Figs. 2 and 3. An arm 432 on the solenoid then rooks a shaft 427 having a number of reject fingers 426 secured thereto, so that the fingers move downwardly below the lower run of the suction belts 414 and strip the superposed sheets from the belts. The rejected sheets fall into a reject tray beneath the belts.

Title: Improvements in or relating to automatic control systems
IPC: F41G7/22
Filed: 1959-11-06
Abstract: 968,535. Automatic steering control. LAMAS DEVELOPMENTS Ltd., and A. D. PHILLIPS. Nov. 4, 1960 [Nov. 6, 1959], No. 37732/59. Heading G3R. In a system for automatically steering a vessel, a signal dependent on course error operates a steering device until reduced to zero by feedback dependent on the extent of movement of the steering device, and thereafter the feedback is progressively reduced so that if course is not corrected at the same rate as the feedback reduces, the steering device is actuated again. In Fig. 2, upon deviation of a ship from a desired couse, a repeater compass 3 operates a shutter (not shown) so that light from a lamp 8 or 9, according to the sense of deviation, illuminates a photo-transistor 6 or 7 so that, through a transistor operated relay A/4 or B/4 and a further relay C/1 or D/1, a steering motor 16 is rotated in the appropriate direction to correct the course. Release of the relays is facilitated by auxiliary contacts A1, B1 controlling transistor operation. While motor 16 is running, its back e.m.f. is effective to charge a condenser 20 or 21 through resistors 18, 25 so that a meter 19 is deflected to an extent dependent on the amount of course correction. The pointer (not shown) of meter 19 applies negative feedback to the system by moving the compass shutter until motor 16 is stopped. Thereafter condenser 20 or 21 discharges through a resistor 23 or 22 so that the feedback dies away, and if the restoration of the ship to course takes place at a different rate, motor 16 is switched on again in the appropriate direction. A relay E/1 operated by the back e.m.f. of motor 16 ensures that the latter is disconnected from the condensers while discharge takes place and a relay F/1 similarly operated controls a motor starting resistor 32. A condenser 30 is provided to damp meter 19 when motor 16 is not energized. A resistor 10 controlling the intensity of lamps 8 and 9 is included among controls which are adjustable to suit weather conditions.

Title: Process for automatically controlling the conversion distribution in reactor series operating with continuous flow
IPC: B01J19/00
Filed: 1964-09-18
Abstract: The conversion distribution of a polymerization reaction (e.g of butadiene, v.i.) taking place in at least two cooled reactors in series operating with continuous flow is controlled by (a) determining the rate of dissipation of heat from at least the first two reactors in the series, (b) computing therefrom either pneumatically or by electrical analogue the heats of reaction or conversion rates in said reactors, (c) applying a signal determined by the heat of reaction or conversion rate in the first reactor to control the flow of catalyst to said reactor so as to provide the desired conversion rate therein irrespective of temperature changes therein and (d) applying a signal determined by the heat of reaction or conversion rate in the second or following reactors to control the first reactor or the reactor preceding said following reactors so that sufficient catalyst reaches the second or following reactors to provide the intended conversion rate therein.  The process is illustrated in connection with butadiene polymerization in a series of five reactors using a benzene solution of 1:3-butadiene with a diethylaluminium monochloride/cobalt salt Ziegler catalyst formed in situ, the first two reactors being controlled as above defined, the cobalt salt being separately introduced and regarded in this case as the "catalyst".

In a process for making a conveyer belt reinforced with steel cords, lengths of steel cords are first unwound and then tensioned individually in a parallel array, and united in the array by vulcanizing rubber thereon while they are tensioned. The steel cords are unwound from drums 1 and guided over a grooved roller 3 through a tensioning clamp 4, two sets of tensioning rollers 5a, 5b, 5c, grooved roller 6, clamp 7, and grooved roller 8, to receive a rubber sheet before passing through a pre-forming and vulcanizing presses 10, 11, respectively, and between tensioning rollers 12 and a clamp 13 to a receiving drum 14. The cords are tensioned initially by closing clamp 4, and moving the drum 14, clamp 13, and tensioning rollers away from the clamp 4. The stresses in the cords are then equalized by adjustment of the tensioning rollers 5a, 5b, 5c. The clamp 7 is then closed and the presses 10, 11 moved towards it to perform the moulding and vulcanization operations.

Abstract: 897,637. Automatic temperature-control systems. FOSTER INSTRUMENT CO. Ltd. Dec. 3, 1958 [Dec. 10, 1957], No. 38367/57. Class 38 (4). [Also in Group XL (b)] In an electrical controller, a current is caused to fluctuate cyclically about a mean value and a movable member responsive to the current fluctuates towards and away from a position in which it initiates a control action. As shown, a thermocouple 1 is connected in series with a moving-coil instrument 3 and a variable resistor 5. The thermocouple current is cyclically varied about a mean value by a shortcircuiting slider 9 moved across the resistor 5 by a bi-metal strip 10 heated by an element 11. A switch 13 is actuated at the limit of travel of the slider 9 to disconnect the element. The thermal inertia of the element and the bimetal strip is such as to cause the slider to move cyclically to and fro across the resistor; the cycling rate is adjusted by a resistor 14. A pointer 3a of the moving-coil instrument carries a vane 3b that at a pre-determined position interrupts a light beam from a lamp 6 to a photo-transistor 7 to de-energize a relay 8 controlling the supply of energy to a furnace. The ratio between the on and off times of the relay is determined by the thermocouple current and -tends to maintain the furnace temperature constant. The bi-metal strip 10 and coil 11 can be replaced by a crank mechanism with an adjustable throw.
