Abstract: 1,274,284. Automatic control of speed. T. B. WOOD'S SONS CO. May 21, 1969 [May 22, 1968], No. 51303/71. Divided out of 1,274,283. Heading G3R. The description is identical to that of the parent Specification but the claims are directed to the use of a capacitor (340) in the circuit which comprises the feedback signal with a control signal so as to nullify the effects of high frequency pulses present in the feedback signal while enabling an amplifier to respond to its average value.

Abstract: 1,198,139. Developing electrostatic images. RCA CORPORATION. Nov. 10, 1967 [Nov. 10, 1967], No. 51319/67. Heading G2H. [Also in Division B2] Liquid is applied to the surface 12 of a record sheet 24 by a head 30 reciprocated over the surface by a chain 56. The liquid may be water, a liquid developer consisting of toner particles dispersed in a carrier liquid, or a rinse liquid e.g. (Registered Trade Mark) "Freon TF". The head 30 has a removable liquid supply conduit 32 within a liquid removal conduit 34. A metal manifold 74 fixed to an electrically insulating block 64 Fig. 4 (not shown) has a longitudinal slit 76 Fig. 3, to provide the required rate of liquid flow from any one of tubes 14, 16, 18, 20, 22. The manifold 74 may be electrically biased with respect to a conductive support for the sheet 24. Exhaust conduits 82, 84 are enlarged at (83), (85) Fig. 2 (not shown) for connection to exhaust hoses 94, 96 Fig. 1, connected through a hose 98 to a vacuum pump. Air at atmospheric pressure is drawn into the head 30 through conduits 100 and 102 and in the direction of arrows 82a, 84a, thus removing excess of liquid deposited on the surface 12 and preventing liquid leaking out from under the head. An electric heater 103 reduces condensation within the head 30 during operation.

In a first embodiment (Fig. 1) the wall is constituted by three superimposed tubes 6a, 6b, 6c and the floor 2 is stiffened by concentric members 3, non-radial members 4 and taller radial bulkheads 7 e.g. 7a1, 7a2 which divide the base into open topped compartments. The structure is towed to its site with these compartments at least partially filled to provide stability and there sunk by flooding compartments in the tubes and ducts in the legs which have valves 10a-d for controllably connecting these ducts to the ambient medium. In plan the base may be circular, polygonal square or rectangular and may have a roof structure (not shown) above the floor 2 which with the peripheral wall encloses a chamber for storage purposes. To secure the platform to the bottom, the floor 2 may carry on its underside depending projections which engage the bottom material or it may have apertures with depending divergent nozzles through which gravel passes from storage compartments on the floor 2 when the apertures are opened by remote control (Figs. 9 and 10: not shown). In an alternative embodiment (not shown) the peripheral wall of the base is formed by one tube supported by two vertical circular walls and the space so defined may be used for ballasting or storage. A perforated roof structure may be provided above the floor and projections on the underside of the floor define compartments which can be partially evacuated to create a pressure gradient and thereby facilitate penetration of the projections into the bottom material.

Abstract: 1,126,671. Making wire strand; creels. BRITISH ROPES Ltd. 20 Dec., 1965 [22 Dec., 1964; 2 June, 1965], Nos. 51983/64 and 23558/65. Headings D1J and D1T. A method manufacturing a wire strand, comprises supporting a plurality of supply packages 2, Fig. 1A, of round wire on means 5 in stationary attitudes, leading wires I from the packages 2 to a plying point 6, pulling a resultant plied strand away from the plying points while the strand rotates, restraining rotation of each wire I at a first point 4 between the package 2 and the plying point 6, and positively rotating each wire about its own axis at a second point 7 between the first point 4 and the plying point 6 at a speed so related to the speed of rotation of the strand at the plying point 6, and the rates of pulling of strand away from the plying point 6, that each wire undergoes elastic and plastic tortional deformation on passing the first point 4, and undergoes at least partial elastic recovery on passing the second point 7. As illustrated the means for positively rotating each wire about its own axis at the second point 7 comprises two pulleys mounted in a rotating carrier, the wire being wrapped around each pulley and the groove of each pulley being in a plane containing the axis of rotation of the carrier. In a modified construction there is only one of these pulleys per wire. The means at the first point 4, for preventing the twist in the wire from travelling back to the package 2, comprises at least one pulley tangential to the axis of rotation of its associated carrier at the second point 7. The or each of these pulleys rotate about a fixed axis and the wires are wrapped round these pulleys. In Fig. 1A, the core wire 18 is supplied from a separate package 44. In a preferred form of the method each wire undergoes between two and ten twists per length equal to 100 times the diameter of the wire. Each wire between the first point and the second point may have an unsupported length not exceeding 500 times the diameter of the wire. The apparatus includes a cage 26 which rotates and carries rollers 28 that nip the strand to make it straight and of uniform construction, and to neutralise tortional stresses. Fig. 1B, (not shown) shows the pulling means 10 for the wire. The pulling means comprises a drum 62 around which the strand 8 is wrapped several times, the drum rotating about its own axis as well as the axis of the strand 8 by means of a supporting frame 58 mounted in trunnions 56. Fig. 1B, also shows a take-up drum 94 mounted in a non- rotatable cradle 92 surrounded by a flier frame 12. The device 162 in Fig. 1A, is a tensioning device.

Title: Electrical Stepping Motor Control System

Filed: 1968-11-19
Abstract: 1,175,918. Control of stepping motors. INTERNATIONALE BUSINESS MACHINES CORP. 19 Nov., 1968 [26 Dec., 1967], No. 54811/68. Heading H2J.  A signal for starting a stepping motor in either direction is applied to an OR-gate 56 to initiate a single-shot 54 and provide a signal through OR-gate 48 and a stopping sequence generator 18 which produces a pulse for the motor. An up-to-speed latch 52 deactivates a discriminator 42 by removing its output from AND-gates 38, 40. Removal of a signal from latch 52 to AND-gate 46 blocks pulses from oscillator 43 passing through gate 48. A signal from latch 52 allows feed-back pulses from gate 34 to re-set oscillator 43 through gate 60, and to re-set a binary trigger 45. Movement of the motor generates feedback pulses through transducer 20a which pass through gate 34 to initiate an output from single-shot 36 and re-set the oscillator 43 to maintain it in synchronism with the feed-back pulses. The feed-back pulses are also applied through gates 47, 48, and generator 18 to effect stepping of the motor.  The latch 52 is re-set by a feed-back pulse when its interval is shorter than the oscillator period. This prevents further resetting of the oscillator 43 and stops feed-back pulses arriving at the output by blocking gates 60, 47. The inverted feed-back signal from unit 32 sets a latch 66 which is re-set by the oscillator, which also re-sets latch 64. Coincidence of feed-back pulses, with latch 66 being on, re-sets the latch 52 and transfers the control of the stepping motor from the feed-back pulses to the oscillator output. The output of the single-shot 36 is applied through gates 38, 40, to the discriminator 42 for determining the sampling period thereof and the magnitude of the stored error voltage. A correction is made by comparing the phase relationship of the oscillator with that of the feed-back signal. When the signal applied to gate 56 is terminated inverter 70 blocks gate 48 to inhibit the application of further feed-back pulses to generator 18. A signal from inverter 70 acts through resistor 77 to permit the next pulse from trigger 45 to reset a latch 76 through capacitor 78. The latch 76 applies a signal to the generator 18 which produces a train of three pulses at predetermined intervals to stop the motor.
