Title: Signal transmission circuits
IPC: H03H7/48
Filed: 1970-10-29
Abstract: 1322202 Phase shifters; matching impedances WESTERN ELECTRIC CO Inc 29 Oct 1970 [4 Nov 1969] 51428/70 Heading H1W [Also in Divisions H3 and H4] A signal transmission circuit includes an input network 19 having an input branch and providing n equal in phase signal components at n output branches 21, 22, 23, where n is greater than two, an output network 20 having n input branches 21<SP>1</SP>, 22<SP>1</SP>, 23<SP>1</SP>, and an output branch for combining n inphase signal components in the n input branches inphase in its output branch, the networks being match terminated for out of phase signal components, and n branch circuits 30, 31, 41 for coupling each of the n output branches to a respective one of the n input branches, the branch circuits including a first group of phase shifters 33, 35, 37 for providing relative phase shifts between one and each of the others of the n input signal components, each relative phase shift being different and substantially equal to 180 m/n. degrees or an integral multiple thereof, where m is less than n and a second group of phase shifters 34, 36, 38 for producing an inphase relationship among the n signal components coupled to the output network. The input and output coupling networks 19, 20 are disclosed in Specification 1,165,202 and may include capactive coupling as shown via conductive rings 28, 29 or may include inductive coupling (Fig. 3, not shown). The input and output networks 19, 20 are terminated by resistive terminations 24, 25. An input signal produces equal in-phase branch signals in conductors 21, 22, 23 and amplifiers 39, 40, 41 are connected between the phase shifters which may be formed from different lengths of transmission line. The phase shifts introduced by phase shifters 33, 35, 36 are correspondingly altered by phase shifters 34, 36, 38 so as to produce in-phase signals at the output conductors 21<SP>1</SP>, 22<SP>1</SP>, 23<SP>1</SP>. Signals reflected by each amplifier 39-41 back towards the input network 19, due to mismatch of the amplifiers, propagate through the phase shifters 33, 35, 37 twice and sum to zero in ring 28. At termination 24 they produce a net voltage between pairs of conductors which is dissipated in this termination. Similarly any out of phase signal components produced by distortion in the amplifiers are absorbed in termination 25. The phase shifters may have an input quadrative hybrid coupler (71, Fig. 4, not shown) connected to a 180 degree coupler (72) which feeds an output via a quadrative coupler (73). A unity input 1<0 degrees (at a) producing a sin#+i Cos#= i# - i# output (at m). When the relative phase shifts in the branch circuits differ by multiples of 360/n (i.e. m = 2) spuriously generated harmonics of the signal frequency are suppressed by the output network. The introduction of the Specification discusses using transistors and tunnel diodes.

Abstract: 1,196,619. Holography: stroboscopic apparatus. BRITISH AIRCRAFT CORP. Ltd. Jan.21, 1969 [Nov.13, 1967], No.51587/67. Headings G2C and G2J. A method of recording the vibrations of the surface of an object comprises recording a hologram 15 of a stationary object 13, vibrating the object 13 and stroboscopically illuminating the object with coherent light 9, 12 through a rotating slit disc 20, such that the vibrations are frozen over the surface of the object, and then reconstructing the hologram to form a reconstructed object coincident with the illuminated vibrating object whereby an interference pattern of fringes appears across the object, the apparent location of the fringes representing loci of equal amplitudes of vibration. In an alternative embodiment the stationary object is recorded as a first hologram 15, and then the stroboscopically illuminated vibrating object is recorded in the same medium to form a second hologram. The double hologram is reconstructed to form coincident reconstructed stationary and vibrating objects with the same fringe patterns as above. By altering the viewer angle the fringe pattern variations can be observed. If desired a pulsed laser may be used in place of the rotating slit disc.

Abstract: 1,175,064. Consolidated sheets; laminates; films. FORMICA CORP. 21 Nov., 1966, No. 52086/66. Headings B5A, B5B and B5N. [Also in Division B2] Consolidated, dense, plastics sheets are produced continuously by introducing finelydivided non-sintered thermoplastic polymeric material into the nip between a pair of flexible, continuous metal belts, heating it to at least its softening temperature in a first, heating, zone between the belts, continuously moving the heated material to a second, densifying zone between the belts, the spacing between the belts in the densifying zone causing greater compression than in the heating zone to conlidate the material into a sheet-like mass, cooling it below its softening temperature while continuously removing the material from the densifying zone, and cooling it to room temperature. The process is suitable for use with " intractable " materials, e.g. polyethylene, polypropylene, poly-(methylmethacrylate), a polyimide or a polyacrylonitrile, or heatdegradable materials, e.g. light-stabilized polyvinyl chloride. Other materials are also specified. Reinforcements, e.g. paper webs, fabrics of natural, synthetic or glass fibres, asbestos fibres or metal foils, may be incorporated by being introduced between the belts. The polymeric material may be applied to one or both sides of the sheet of reinforcing material or between two such sheets. In Example 10, eight sheets of glass fabric, impregnated with a solution of a polyimide are laminated together between the belts.

Abstract: 1,056,479. Bag filling apparatus. IMPERIAL CHEMICAL INDUSTRIES Ltd. Dec. 6, 1965 [Dec. 23, 1964], No. 52268/64. Heading B8C. In apparatus for simultaneously filling a bag or sack and placing it in an enclosure, the bag body is supported outside the enclosure, while its mouth is clamped above the enclosure, so that, as the bag is filled, the weight of the contents causes the bag body to slide over the top of and into the enclosure. In the embodiment, a pivotable clamp 3, to which a polythene bag 4 is attached, when in the position of Fig. 1, is pivoted down until it is directly above a clamp 2, from which a jute sack 1 is suspended, Fig. 2 (not shown). In this position, the body of the bag 4 is arranged across the mouth of the jute sack and is supported by a plate 5 attached to the clamp 2. The bag is then filled through a spout, the spout either being movable with the clamp 3 or being situated directly above the clamp 2. The filling preferably takes place in two stages, the weight of the first discharge being sufficient to drag the bag into the sack, Fig. 3 (not shown), while the second discharge takes place after the bag is correctly positioned, Fig. 4 (not shown). Both clamps are then released.

Abstract: 1444919 Time division multiplex switching GENERAL ELECTRIC CO Ltd 14 Nov 1973 [14 Nov 1972] 52446/72 Heading H4K In a time-space-time switch for switching between incoming 10, 12 and outgoing 14, 16 TDM highways, a predetermined test-pattern is inserted into an incoming time slot and the outgoing time slot into which information in the incoming slot is switched is checked to see that the test pattern has been correctly received. Time switching.-To connect an incoming channel X on highway 10 to outgoing channel Y on highway 14 the speech address memory 50 of time switch and the speech address memory 54 of time switch 28 are examined to find a location A which is free in both memories, which is then marked "busy". Since the switching of the cross-point switches 36-42 is effected by cross-point address memories 44-46 at the same rate as the incoming and outgoing channel rate, a space-switch time slot A has thereby been found in which the required cross-point switch 36 is operated. Data x in incoming slot X is switched into space switch time slot A under the control of speech memory 48, speech address memory 50 and cross-point address memory 44, and hence passes to outgoing time switch 28. Here it is switched into outgoing time slot Y, under the control of speech memory 52 and speech address memory 54. Control of all the memories 44-54 is effected by supervisory signals from a switch control unit. Testing.-Each time the switch control provides data giving the identity of a calling incoming channel, a test pattern generated 104 becomes operative. The generator prevents the incoming data in the time slot to be tested from being inserted into the speech memory 48, replacing it with a test pattern. Two different patterns are inserted into alternate frames, one pattern being the logical complement of the other, e.g. 10101010 and 01010101. In this way both polarities of the circuitry are tested. When the test pattern has been switched through the system, it is checked by a checking logic circuit 105. In a further embodiment, Fig. 3 (not shown), multiplexing takes place within the incoming time switch.

Abstract: 1,160,039. Gyroscopic apparatus; accelerameters. GENERAL MOTORS CORP. Nov. 23, 1967 [Dec. 8, 1966], No.53312/67. Headings G1C and G1K. A gyroscopic device which is sensitive to changes of acceleration or rate-of-turn of a vehicle on which it is mounted, comprises an annular rotor 10 connected by aligned torsion bars 12,14 to a drive shaft 16 rotated by a motor 18, two permanent magnet masses 20, 22 being mounted on the rotor 10 so as to displace its centre of gravity axially from the pivot axis X defined by the bars 12,14, the shaft 16 in operation being rotated at an angular frequency equal to the natural oscillatory frequency of the rotor 10 about the torsion bars, oscillatory deflections of the rotor caused by acceleration along the Y-axis or by angular rotation about the same axis being detected by E-core pick-offs 26,28 disposed on the periphery of the rotor 10 along the X-axis. Pivoted movement of the rotor about the torsion bars 12,14 is limited by the provision non-magnetic members 42, 44 which carry torquer windings 46, 48 and which extend into slots in the magnetic masses 20,22. The windings 46,48 are fed with signals derived from the pick-offs 26, 28 and in this way a torque pulse will be delivered to return the rotor to its null position each time one of the members 42, 44 passes through the slots in the masses 20, 22. The torqueing member may be formed of one annular member in place of the two discrete sections if desired. A second embodiment is described in which acceleration and rate inputs can be differentiated. In this embodiment the shaft 16 carries two annular rotors, as 10, disposed with their torsion bars parallel. The centres of gravity of the two rotors are displaced by the magnetic masses in opposite directions axially from the respective torsion bar pivot axis and in this way an acceleration input will cause equal but opposite deflections of the rotors, whilst a rate input will cause equal deflections in the same direction. The resulting oscillations of the rotors will thus be either out of phase or in phase respectively, and by use of suitable logic and summation circuitry signals indicative of the acceleration and rate inputs are obtained. Sets of pick-offs are also provided in this embodiment disposed along the Y-axis, so as to sense acceleration and rate inputs along or about respectively, the X-axis.
