Patent GB-761762-A (GB)
Title: Microwave transmission systems and impedance matching devices therefor
IPC: H01P5/18
Filed: 1953-05-01
Abstract: 761,762. Impedance matching. STANDARD TELEPHONES & CABLES, Ltd. May I, 1953 [May 8, 1952], No. 12111/53. Class 40 (8). A discontinuity in a transmission line of the " line-ground " type described in Specifications 704,050, 708,601 and 761,764 is tuned out by means of a further discontinuity separated from the first discontinuity by a resonant spacing. Fig. 1 shows a junction between a " lineground " transmission line and a coaxial cable in which the outer conductor 4 of the coaxial cable is connected to a " ground " conductor 2 and the inner conductor 5 to a comparatively narrow " line " conductor 1. The conductors 1, 2 of the transmission line are separated by a layer 3 of dielectric a small fraction of a quarterwavelength thick. According to the invention, the mismatch presented by the junction is tuned out by a piece of wire 7 spaced from the junction by a distance d smaller than half a wavelength. The wire 7 is soldered in position, adjustments being made whilst the solder is still molten. The wire 7 may extend around the edge of the dielectric layer 3 to contact the " ground " conductor 2, thus forming a short circuit. Such a shorting loop may be formed integrally with the line conductor 1, adjustment being effected by cutting away portions of the loop to increase its distance from the junction. A further form of tuning susceptance (Fig. 6, not shown) comprises a short conductive post extending through the dielectric layer between the two conductors. In the modification of Fig. 7, the susceptance is formed by a step 28 in the width of conductor 1. To adjust the susceptance, portions 31, 32, 28a of the conductor 1 are cut away or extra conductive material is added in the form of solder. The susceptance may be in the form of a pair of short lateral extensions on either side of the line conductor 1. These may be gradually curved into the edge of conductor I on the side of the lateral extensions remote from the junction. A further form of tuning element for the resonant space between the junction and the susceptance comprises a threaded post which extends by a variable amount into the dielectric layer 3. Specification 708,598 also is referred to.

Abstract: 1,081,524. Movable magnet switches. WILLIAM EWART & SON Ltd. Jan. 26, 1966 [March 23, 1965], No. 12190/65. Heading H2B. [Also in Division D1] A thread-break detector specially for use in the wet-spinning of linen comprises a permanent magnet movable between two positions to actuate a reed contact device and connected to a feeler which engages the yarn and holds the magnet in one of the two positions against the influence of another magnet urging the magnet towards the other position. The contact device 13 is carried in clips bent out of a bracket 14 of non-ferrous material. Upstanding from one of the clips near the contacts is a pin on which is rotatably mounted a cap 16, bearing, at right-angles to one another, a bar magnet 17 and a feeler arm 18. A second magnet 19 is carried by the bracket and tends to rotate the first magnet to a position where it closes the contacts, but the magnet is prevented from so rotating when a thread engages the end of the feeler. When the thread fails, the magnet is free to rotate and close the contacts to operate a stop motion or a signal or both. The end of the feeler is of U-shape to prevent the arm being released when the yarn balloons; the U-portion is coated with P.T.F.E.; a small weight is disposed near the U-portion to dampen vibrations, and when the device is used in a wet environment, the external parts are of brass, stainless steel or are coated with plastics. A soft iron pin may be used to limit the rotation of the magnet and to hold it clear of the yarn-track when desired.

Patent GB-1219984-A (GB)
Title: Sensing device for a tape cartridge
IPC: G03B17/26
Filed: 1968-03-14
Abstract: 1,219,984. Tape cassette apparatus. PIONEER ELECTRONIC CORP. 14 March, 1968 [18 March, 1967; 17 April, 1967], No. 12487/68. Heading G5R. A two-part sensing device to be fixed to a cartridge tape recorder detects whether a cartridge includes a pinch roller or not and operates to swing a pinch roller in the recorder into an operative position accordingly. As shown, the pinch roller 1 is journalled on a plate 4 arranged to be rotated on a rod 3 against the force of spring 6 by a slide 9 carrying a pivotal member 13 itself carrying a first, sensing slide 16 having a cartridge-engaging end 16c. A second, sensing lever 21 is pivoted at 22 to the base and has a cartridge-engaging end 21a and a portion 21b designed to engage the pivotal member 13. When a cartridge is loaded the leading edge engages end 16c of slide 16 and begins to move the slide 9 to thereby raise the pinch roller 1, spring 19 coupling the member 13 and slide 16 being stronger than springs 20 and 6 together. If the cartridge has an aperture to receive a pinch roller, the slide 9 continues to move as the cartridge is loaded and when lever 21 is rotated by the cartridge its portion 21b clears pivotal member 13 and has no effect. The pinch roller 1 is held raised by co-operation of a magnet 8 with a flange 7 on the plate 4. If the cartridge contains its own pinch roller, Fig. 2, and therefore does not have a pinch roller aperture, the slide 16 is pushed relative to the member 13 against spring 19, since the pinch roller 1 then lightly engages the under-side of the cartridge, until the lever 21 is rotated by the cartridge so that the portion 21b engages the member 13 to deflect the slide 16 and allow the slide 9, and thereby the pinch roller, to be retracted. A modified device is described (Figs. 5 to 8, not shown) in which the lever 21 is replaced by a slidable and rotatable member (121) having a locking end (121b) engageable with a portion (113b) at the pivoted end of the member 13.

Title: Improvements in or relating to statistical machines
Filed: 1949-05-10
Abstract: 665,175. Punching record cards. REMINGTON RAND, Inc. May 10, 1949 [June 10. 1948], No. 12491/49. Class 31 (ii). A machine for punching statistical record cards includes differentially settable character - indicating elements, for example typecarrying elements, and follower means to follow the movement of said indicating elements, together with a differentially movable sensing bar co-operating with the follower means to sense the position thereof, a restoring bar for said sensing bar, a gag bar set differentially by the sensing bar, a lock to prevent advance of the sensing bar and a release for the lock acting only on certain cycles of the machine. The machine is provided with differential set-up mechanism on which data from a tabulating machine is stored in one cycle to be punched at a subsequent cycle, usually in combination with other data introduced into the tabulator in the meantime. This set-up or storage mechanism is capable of retaining a set-up for a plurality of punch cycles and it can also be set-up so as to be retained indefinitely, some matter being punched in all of a series of cards. The tabulator is substantially the same as that described in Specification 555,823, [Group XIX], and includes a sensing pin box 125, Fig. 4, which is reciprocated vertically, set-pins 127 and associated wiring unit 128, Fig. 3, and type-bars 135 whose setting is transmitted via sensing- levers 160 and slides 163 to Bowden wires 169 which communicate with the punch. The punches 293, Fig. 20, are operated through setpins 300 and locking slides 301 carried in a vertically-reciprocated set-pin box 296. Selection of the required punches is effected through plungers 336 selected by appropriate Bowden cables 321 housed in a removable wiring unit 311 which reciprocates with the set-pin box. Plungers 320, Fig. 13, carried in the top of the wiring unit coact with projections on gag bars 364 set in position, through pawl and ratchet mechanism, by sensing-bars 363. A Bowden wire 169 is secured to a projection of each typebar slide 362 which when moved towards the right will draw after it the wire 169 which in the tabulator, Fig. 3, draws one of a number of slides 163 towards the rear of the machine, swinging a sensing lever or bell-crank 160 counter-clockwise until arrested by the bottom of the type-bar in some numeric position. The rightward motion of the slide 362 will, therefore, be limited to one of ten positions appropriate to the numerals 0 to 9. The type-bar slide 362 is moved rightward by the sensing-bar 363, a projection 366 on which contacts a projection 367 on the slide 362. Each sensing bar is propelled by a spring (not shown) but is normally held in its extreme left-hand position by a reciprocatory universal restoring bar, not shown. When at the appropriate time this restoring bar moves to the right the sensing bar 363 follows it under the force of its spring and pushes the type-bar slide 362 with it until both of them are arrested in the appropriate position. Specifications 494,522 and 601,099, [both in Group XIX], also are referred to.
