Title: Electronically variable delay
IPC: H03H17/00
Filed: 1965-03-12
Abstract: 1,105,432. Automatic phase control systems; line transmission systems. STANDARD TELEPHONES & CABLES Ltd. (International Telephone & Telegraph Corporation). 12 March, 1965, No. 10676/65. Headings H3A and H4R. A variable delay line comprises a plurality of delay sections 1-3, Fig. 1, each of a value one half that of the preceding section, a by-pass associated with each section, and switch means S1-S4 for selectively cascading the delay sections to produce a desired delay. As shown in Fig. 1, the delay line may be controlled by a binary counter, each pair of switches connecting one section to a succeeding section being controlled via a. logic circuit 34 in accordance with the state of one stage and two succeeding stages of the counter. Four outputs from the delay line on terminals 00-11, Fig. 6, are connected to respective segments of a pair of segmented switches 361 and 362 whose rotary contacts are driven in common by the switch control 364 responsive to stages f6 and f7 of the binary counter. When one rotor is situated centrally of a segment the other rotor is situated in the gap between segments which are connected to delays differing by one unit above and below that connected to the first rotor. A rotary potentiometer 263 connected between the two rotors is driven by the final stages of the binary counter and smooths the transitions from one desired delay to the next. Phase-locking signals from magnetic tapes.- Fig. 7 shows a system for combining several telemetry tape recordings into one, and producing the best composite record. In Fig. 7 one tape record is the master, and a second tape record is the slave, and the two tapes are initially positioned so that the slave tape is several milliseconds behind the master. The two recorders are started and timing pulses on the tapes are compared and used to control the speed of the slave capstan. When the tapes are almost in phase, an output from correlator 2 inhibits this servo control of speed, and the signals are brought into phase by the delay unit 3 which is as shown in Figs. 1 and 6. The slave signal is delayed in unit 3 and the delayed slave signal and the master signal are converted to higher frequencies in units 4 and 7 and brought into phase by a phase correction unit 5 which operates on the local oscillator of converter 4. The signals are then fed to a combiner 6, a down-converter 9, and a recorder. The signals are also fed to correlator 2 which produced a positive or negative output according to whether the slave leads or lags the master; the sign of the output determines whether clock pulses feeding the binary counter (Fig. 1) controlling the delay line in unit 3 are fed additively or subtractively. The first significant digit in the counter may control the slave capstan to prevent the time delay between master and slave exceeding that which can be compensated by the delay line.

Title: Ferroelectric device, ferroelectric body and method of fabrication thereof
IPC: H01G7/06
Filed: 1963-03-18
Abstract: 1,005,080. Ferroelectric devices. RADIO CORPORATION OF AMERICA. March 18, 1963 [March 30, 1962], No. 10674/63. Heading H1K. A ferroelectric body or layer is formed of ferroelectric particles in a binder, a proportion of the particles being of acicular form with their long geometric axes extending predominantly in a common direction. The body may be formed by gravity feed of a liquid suspension of the particles on to a revolving metal drum 55, Fig. 2. Between the drum 55 and an electrode 59 is applied an electric field to align the particles with their ferroelectric axes parallel to the field prior to solidification of the binder. The dry coating 21 may then be cut, punched, or otherwise formed to any desired shape. Alternatively, the suspension may be coated on a foil or web, of either insulating or metallic material, to form a recording medium in which the ferroelectric axes may be aligned with either the thickness, Fig. 4 (not shown), or the breadth, Fig. 7 (not shown), of the layer by a transverse electric field. The layer may be instead used as a capacitor by means of electrodes either on or in the binder. Known compounds, which are photo-conductive, of elements in Periodic Groups V and VI and VII may be used for the particles, such as antimony or bismuth with sulphur or tellurium, with chlorine or bromine or iodine. Organic materials suitable as a binder are also mentioned.

Title: Improvements in power transmissions for cycles with auxiliary motors
IPC: B62M25/00
Filed: 1952-04-28
Abstract: 710,991. Centrifugal friction clutches. ATELIERS DE LA MOTOBECANE. April 28, 1952 [Nov. 30, 1951], No. 10692/52. Class 80 (2) [Also in Group XXXI] A cycle with an auxiliary motor is provided with an automatic centrifugal clutch, consisting of a supporting plate 2 on which are pivoted at 17 at least two masses 3 and associated clutch shoes 6, the internal periphery of a drum 1 being engageable by the shoes, and is characterized in that the drum is fixed on the output shaft 16 of the motor while the plate is freely mounted on that shaft and is connected by transmission to a road wheel. The masses are held inwardly, to keep the clutch disengaged until the cycle has achieved a speed slightly in excess of walking speed, by springs 5, and carry sockets 9 through which pass freely rods 10 fixed in pivoted sockets 7 in the clutch shoes; plates 12 and 13 on the rods 10 are separated by springs 11 transmitting the clutch engaging force. The arrangement is such that the low speed centrifugal engaging force of the weights is multiplied by the lever system; alternative multiplication means, such as cams, or the position of the friction linings on the shoes, &c., may also be employed. Stops 15 are provided on the clutch shoes and are engaged directly by the centrifugal masses, when a sufficiently high speed of revolution of the driven parts is achieved, so that at still higher speeds the centrifugal forces produced thereby are not multiplied by the lever system to an extent which damages the clutch; alternatively the stops 15 can be provided directly on the plate 2 or a part rotating therewith. When the cycle slows down, the centrifugal clutch disengages as walking speed is approached; so that the motor does not stall. The coil springs 11 shown may be replaced by, e.g. blade springs, rubber blocks, torsion bars, &c.

Abstract: 457,845. Making woven wire fabrics. TENNANT, W. J., 111, Hatton Garden, London.- (Buell, E. J.; Niagara Falls, New York, U.S.A.) April 14, 1936, No. 10736. [Classes 83 (ii) and 83 (iv)] Soldering; uniting by fusion.-The ends of woven wire fabrics such as Fourdrinier belts, are soldered or fusion - welded together by progressively moving a heat applicator such as a torch by power actuated means across the fabric. The fabric may be passed round rolls and is arranged with its ends over a bed 12, Fig. 3, of width equal to that of the fabric. Over the bed is arranged a guide beam 14 provided with a rack 36 for traversing a box-like carriage 30 by a motor 33, Fig. 1, through reduction gear 34 and pinion 35. The beam is transversely adjustable by hand-operated screws 24 on guides secured to columns 17. The carriage is provided with pressure adjusting screws 45 on which a vertically adjustable cradle 40, 41, 42 is mounted. The part 42 of the cradle is formed with T-shaped guideways 48 for receiving the blocks 46 for conducting heat away from the fabric. The blowpipe 50 is mounted in a member 51 secured to the blocks 46. When joining the ends in stages intermittently the carriage is traversed into desired position together with the blocks, and the blocks and blowpipe are then moved by hand in the cradle guides to effect the joining operation and the carriage then moved to the next stage. If the joining is to be effected continuously the blocks are clamped to the cradle by a screw 52 and the carriage traversed with uniform velocity along the seam. Weights 54 are applied to the fabric at each side of the joint to hold the fabric in position. A joint may be effected by an interposed fusible metal strip or by an unfused strip coated with fusible metal. In a modification, the blowpipe carriage may be provided with a shoe 70, Figs. 5 and 6, of shape similar to the inverted hull of a canoe, and is traversed in guides 71 in a block 62 so that the ends of the fabric are raised over the shoe and then lowered so as to separate the ends slightly and admit an interposed strip 75 which is passed from a reel 76 through a slot 99 in the plate 78. This plate which carries the blowpipe 89 is provided at one end with the heat-conducting portion 87 having a slot with inclined sides, and at the other end is provided with feet 79 cooperating with the shoe. The plate 78 is mounted on studs 80 screwed in the shoe, springs 82, 83 being provided between the plate and adjusting-nuts 84 and an interposed member 85 so as to press the tail end of the plate 78 into contact with the fabric after the strip 75 has been laid in position. The blowpipe carriage is traversed by an endless chain 91 through reduction gear 97 and motor 95, one run of the chain being secured to the shoe 70.

Abstract: 748,590. Double-glazed units. PITTSBURGH PLATE GLASS CO. Oct. 22, 1953 [Oct. 25. 1952], No. 10750/55. Divided out of 748,576. Class 56 In the making of double-glazed units wherein the edges of two spaced glass sheets are welded together, the carriage 26 conveying the sheets into the welding chamber 11 is made so that it may be withdrawn without the transfer and supporting means in the welding chamber touching the under face of the top sheet or the upper face of the lower sheet. For this purpose the carriage is formed with an open side 32. In the form shown the carriage is run into the welding chamber and supporting means 80 are projected through the bottom of the carriage to engage the under face of the sheet 90 and lift that sheet off the carriage which is then retracted, the open side of the carriage permitting this. The supporting means are now lowered and the carriage again run into the welding chamber where the upper face of the sheet 91 is engaged by a vacuum head and that sheet raised. After the carriage has been again retracted the sheets are brought close together and their edges welded. Alternatively the carriage need be run into the welding chamber once only by placing the upper sheet directly on the lower sheet on the carriage.
