Title: Improved slider for slider-clasp fasteners
IPC: F16F1/38
Filed: 1939-08-30
Abstract: 532,431. Sliding-clasp fasteners. KUNA. J. and BREVETIA, Ltd. Aug. 30. 1939, No. 24923. Convention date, Aug. 30, 1938. [Class 44] The slider of a sliding clasp fastener is held against unintentional opening movement by a slidable plate 31 housed in a recess 30 in the upper wing 14 of the slider and guided by lateral flanges 32. In the position shown in Fig. 2 these flanges are clear of the converging channels 18, 19 and allow free passage of the fastener members. In the other extreme position, Fig. 4, the flanges project into and restrict channels 18, 19 to prevent movement of the slider. Member 31 is moved automatically by frictional engagement with the fastener members so that on closure movement of the slider it automatically assumes the free position, Fig. 2, but any movement of the slider in the opposite or fastener releasing direction moves member 31 to the locking position, Fig. 4, to prevent further such movement, unless the slider is operated by the pull tab 28, in which case a tongue 34 on plate 31 and projecting through a slot in wing 14 is engaged by the end 29 of the pull tab, as in Fig. 1, so that the plate is positively moved to and held in the free position, as in Fig. 2. The above construction avoids damage to the fastener members by the locking device.

Abstract: 448,031. Television. CORK, E. C., 50A, Kenilworth Road, Ealing, London, MANIFOLD, M. BOWMAN-, Heathcot, near Worplesdon Station, Woking, Surrey, and BROWNE, C. O., 29, Monk's Drive, West Acton, London. Aug. 31, 1934, Nos. 25181/34, 29874/34, and 7205/35. [Class 40 (iii)] The framing-signals in an interlaced scanning system have leading edges at a multiple of the strip frequency which is equal to the number of partial scans in a complete scan, and some of the leading edges are in phase with the strip signals. When there are two partial scans to a complete scan, each mirror on a drum 77 sweeps the image of an illuminated aperture 64 over photo-electric cells 81, 68, 69 in succession. The cell 69 is connected to an amplifier in one sense to produce stripsynchronizing signals, and the cells 68, 81 are connected in an opposite sense to produce suppressing-impulses, which occur just before the strip impulses and mid-way between these positions. Long framing-impulses in the same sense as the strip impulses are applied across terminals 72. A valve 71 has grid-bias 73 such that the suppressing-impulses are cut off except during the framing-impulses, and grid current through a high resistance 74 cuts off the strip signals during the framing impulses, Fig. 6 (not shown). According to modifications : the synchronizing-signals are generated as described in Specification 445,912, Figs. 9-12 (not shown) ; or by an apertured disc, Figs. 15-16 (not shown); the synchronizing signals and the suppressing- impulses, which are generated as described in Specification 442,938, are mixed in a hexode and a tetrode valve in parallel, Fig. 14 (not shown).

Title: Improvements in or relating to navigation aiding radar systems
Inventor: WELLS EDWARD MARSHALL
IPC: G01S13/60
Filed: 1962-07-02
Abstract: 983,883. Radar systems. MARCONI CO. Ltd. April 4, 1963 [July 2, 1962], No. 25245/62. Heading H4D. A radar system suitable for use on a hovercraft H, Fig. 1, comprises two directional aerials A and B, mounted on the craft so as to be directed with downward inclination towards a common area of reflecting surface separate from the craft, aerial A transmitting continuous waves of frequency fo and receiving the echoes of these waves from the said area, and aerial B also receiving the said echoes, means deriving signals representative of the Doppler difference fA in the frequencies of the waves transmitted and received by aerial A, means deriving signals representative of the Doppler difference fB in the frequencies of the waves transmitted by aerial A and the waves received by aerial B, and means utilizing the two Doppler frequency responsive signals to ascertain the forward speed and drift of the craft with respect to the reflecting surface, or a compounded resultant of said speed and drift. In a preferred embodiment the aerials are inclined downwards at angles of 45 degrees, and are inclined inwards at angles of 45 degrees to the fore-and-aft line of the craft. It is shown that if d is the drift angle of the craft (i.e. the angle between its fore-andaft line, and direction of motion), v is the velocity of the craft in the fore-and-aft direction, and D is the depression angle of the aerials, then In one arrangement, Fig. 2, aerial A is fed by transmitter T at a frequency fo via a T/R box C. Echo signals received by aerial A are passed to a detector mixer X1, which delivers a signal at a frequency fA to an amplifier A1. Echo signals received by aerial B are passed, together with signals from the transmitter T, to a second detector mixer X2, which delivers a signal at a frequency fB to an amplifier A2. The fA and fB signal outputs from the amplifiers are fed to a first computer U1 which delivers signals representing v and d. These outputs are in turn fed to a second computer U2, together with signals from a compass unit CU, to produce signals representing the course and speed made good or direction and distance made good. These signals are fed to an indicator and/or recorder unit RU to indicate or record, course and speed and/or direction and distance, or may be arranged to continuously predict the position of the craft. The reflecting area is preferably within the " wake " or region of brushed water trailing the craft.

Title: Improvements in or relating to sealing of cavitated assemblies
IPC: B22C7/06
Filed: 1956-08-17
Abstract: 818,381. Core boxes and moulds. OLSON, R. L. Aug. 17, 1956 [Aug. 19, 1955], No. 25247/56. Class 83 (1). [Also in Group XXVI] A sand core-box has the joint-faces between mating-members 20, 33, Fig. 4, sealed by filling a sealing chamber formed by confronting grooves 28, 34 in the joint-faces with a non- metallic sealing material which is bonded in one groove and separable from the other. The sealing material may consist of natural or synthetic elastomer and be introduced into the grooves 28, 34 by pressure or injection, or it can be introduced as a preformed strip into the groove 28 and then pressure-moulded into the grooves 28, 34 by the application of the second member 33. Preferably, the material contains an agent such as nitrogen or ammonia adapted, when heat is applied to cure the material, to release a gas for the purpose of expanding the material into engagement with the walls of the grooves and giving it a cellular structure with an air-tight skin. The material is caused to adhere to the surface of groove 28 by priortreatment of the latter with a bonding-agent. The surface of the groove may be previously etched to perfect the bond. To ensure separation of the material from the groove 34, the latter may be treated with a suspension of graphite or mica-particles. In order that the grooves 28, 34 on the two members 20, 33 may mate, the position where the groove 34 is to be cut in its member is marked by applying a coating of paint to the ungrooved surface of the member 33 and of powder to the areas between the groove 28 of the member 20; the two members are then engaged and upon separation, the position of the groove 34 is indicated. Sand is blown into the mould through ports 22, Fig. 1, vents 23 also being provided. For venting gases during pouring of metal around the finished core, a longitudinal hole is moulded in the core by the temporary insertion of a rod 41 which is sealed at its ends 41a. As local wear takes place on the seal, the affected portion may be cut away and a low-melting-point alloy-insert cast into its place. If desired, one or more such inserts may be initially formed in the seal to assure correct alignment of the members 20, 33. A three-piece moulding- unit comprising two cavitated members 57, Fig. 11, located by pins 56 to form a casting cavity 58, and a blow-plate 54, has the joint between the members 57 sealed by a strip 61 which is notched-out to receive a horizontal sealing strip 62. To seal a core-box having multiple cavities 67, 68, Fig. 12, a double-rib seal 65 is mounted in grooves formed in adjacent walls 63, 64. Ports 66 extending from the cavities are provided with screens 69 to trap sand particles.

Abstract: 615,096. Locking rods. BURMAN & SONS, Ltd., and BRIGGS, W. H. Aug. 26, 1946, No. 25398. [Class 80 (iii)] In vehicle steering mechanism of the rack and pinion type, friction locking means are combined therewith responsive to lateral force exerted on the pinion, and are adapted to be operated only by forces transmitted from the road wheels. As shown, the spindle a of the pinion b carries a roller c in peripheral contact with two smaller rollers d on either side of it, and such that the lines joining the axes of the larger roller with the two smaller are parallel with the direction of pressure between the operative pinion tooth and the contiguous teeth of the rack. The rollers d are carried on fixed spindles i having shoulders and quick pitch oppositely handed screw threads k, and are arranged between the shoulders and thrust pieces n in screw-thread connection with the spindles i, the pieces n being spring pressed towards the rollers d. The spindle a is supported in the housing f by a single bearing at the end opposite to the pinion b, so that a component of the force between the rack and pinion can cause the larger roller c to be pressed into contact with one of the smaller rollers d. On turning the steering column, the roller c will engage one of the rollers d, and frictional contact will cause the thrust piece n to unscrew, to relieve the pressure between it and the roller d, and allow free rotation of the spindle a. In response to forces from the road wheels however the roller c will engage one of the rollers d to tighten up the thrust piece n and lock the spindle a.

Abstract: 1,030,384. Image intensifier systems. BENDIX CORPORATION. June 19, 1964 [July 8, 1963], No. 25497/64. Heading H4F. [Also in Divisions G2 and H1] In an image intensifier, the effect of fixed pattern noise, due to non-uniform sensitivity of the photocathode 4, electron multiplier 10 or luminescent screen 12, is reduced by the provision of a correspondingly non-uniform radiation attenuating member 16. As shown, an intensifier tube comprises an electron-multiplier 10 formed by an array of resistive and secondary-emissive channels, and a luminescent screen 12 on the tube face, which may be a fibre-optic plate 24. The opposite surface of plate 24 carries a silver bromide emulsion film 16 which is initially exposed to light from screen 12 due to uniform illumination of the photocathode 4 and is then developed whereby the optical attenuation of the film is directly proportional to the initial exposure, so that subsequent uniform illumination of the photocathode gives rise to a uniform light output from film 16. In an alternative arrangement, the film 16 is provided on a transparent substrate spaced from the tube and arranged in the image plane of an optical system used to view the screen 12.
