Title: Hovercraft skirts
Inventor: BERCZI CHARLES NICHOLAS
IPC: B60V1/16
Filed: 1967-11-24
Abstract: 1,261,014. Coated fabric. DEERING MILIKEN Ltd. 7 Nov., 1968 [24 Nov., 1967], No. 53620/67. Heading B2E. [Also in Divisions B5, B7 and D1] A hovercraft skirt is made from an elasto- .mer coated, non-square woven fabric of multiply cords, in which the area of void space in the uncoated fabric is at least 5% of the total area, of the uncoated fabric and the twist factor (defined) for the yarns of the cords is from 1.0 to 9.7 and that for the the cords is from 1.4 to 16.8. Preferably the yarn twist factor is 1.6 to 6.3 and that for the cords 2.2 to 10.9. The cords which may be of two or three plies are preferably made of continuous filament organic synthetic fibres, e.g. nylon, with the filaments of the individual yarns lying substantially along the axial direction of the cords. The elastomer coating is natural or Neoprane rubber and is bound to the fabric by an adhesive comprising an adhesive resin and an elastomer. The elastomer may be the same as that of the coating or polyvinyl chloride. The adhesive resin may be a resorcinol-formaldehyde resin and the adhesive may also contain a styrene-butadiene latex or a vinylpyridine-styrene-butadiene terpolymer. The cords of the fabric may be preshrunk by heating and may be coated with the adhesive prior to weaving. The skirt may be made by applying a dip of adhesive composition to the fabric on a padding mangle, drying the so-treated fabric, spread-coating elastomer onto the dried fabric and cutting and shaping the elastomer coated fabric to form a hovercraft skirt.

Title: Improvements in or relating to apparatus for removing dust and waste from textile machines
IPC: D01G15/80
Filed: 1966-11-30
Abstract: 1,148,518. Cleaning textile machines. SOC. ANON DES ETABLISSEMENTS NEU. 30 Nov., 1966 [30 Nov., 1965], No. 53707/66. Heading D1F. In a cotton card, dust and reps generated in the region of the taker-in 3, the entry to the flats 5 and the doffer comb 7 are withdrawn through horizontally extending slots 13 in suction tubes 8, 9 and 10. In the vicinity of the underlying floor, waste fibre produced by the taker-in 3 and main cylinder 4 is entrained by an air current created by a suction mouthpiece 11 extending over the entire width of the machine and of effective cross-section regulated according to the position of a vertically displaceable portion 12<SP>1</SP> of a guide plate. The aspirated waste is delivered by a fan assembly 15 through conduits 16, 17 and 18 to a filter 20 in a casing 19 from which a conduit 22 (opposite an inspection door 21) returns a portion e.g. two thirds, of the air into the region of mouthpiece 11 to provide, under the control of a damper 27, a balanced air circuit, and an elbow directs the remaining air delivered by the fan to a cloth filter sleeve 24 (reinforced by rings and opening into a box 25) and to atmosphere. Periodic and/or automatic opening of a servomotor operated valve 26 discharges dust circulating temporarily under the machine in the space between conduit 22 and mouthpiece 11 and the waste held in readiness in casing 19 and from the inner surface of filter 24 into the suction manifold 28 of a pneumatic conveyor device (not shown) serving a number of machines. A modification, Fig. 4 (not shown) comprises an auxiliary conduit connecting another suction mouthpiece to the box 25 (in this case partitioned) for periodic removal of card flats waste under the control of a shut-off valve mounted on an extended spindle of valve 26 and operating in unison therewith. In another modification, Fig. 6 (not shown) waste collected by tubes 8, 9, 10 and mouthpiece 11 are delivered through conduit 18 into the sleeve filter 24 which constitutes a temporary collecting station. A flapvalve in a three way connection pipe is normally held closed by pressure of air delivered from fan 15 so that mouthpiece 11 is not directly connected with sleeve 24: accumulated waste is periodically and automatically removed to a central pneumatic conveying device and the change in air pressure opens the flap-valve so that additional suction occurs at mouthpiece 11.

Abstract: 1277250 Filters WESTERN ELECTRIC CO Inc 11 Nov 1969 [18 Nov 1968] 55044/69 Heading H1W Filter circuits are constructed using a cascade of bimodal networks all of which are characterized by the same two normal modes, and including means, connecting adjacent pairs of the networks, for converting all of the wave energy from one of the normal modes in one network to the other of the normal modes in the next network. In the Fig. 2 embodiment, each network section 11, 12, 13, 14 is a section of a twinconductor coaxial transmission line having an outer conductor 32, the sections being coupled by phase-inverting transformers 24, 25, and 26 connected between one of the inner conductors and the outer conductor. The filter is energized by a signal source 18 through a hybrid transformer 19 such that, with the source connected to port 1, as shown, conductors 30 and 31 of section 11 are energized in phase i.e. in the symmetric mode, such that section 11 behaves as a length of transmission line of characteristic impedance Z 1 . The signal in conductor 30 undergoes a 180 degree phase shift in transformer 24, such that the signals on the two conductors of section 12 are 180 degrees out of phase i.e. section 12 is energized in the antisymmetric mode, and behaves as a length of transmission line of characteristic impedance Z 2 , where Z 2  is less than Z 1 . Thereafter successive sections are energized alternately in the symmetric and antisymmetric modes, providing characteristic impedances of Z 1  and Z 2  respectively. The filter of Fig. 4 is constructed of a cascade in which each bimodal network section is formed by a pair of quadrature hybrid couplers, the two couplers of each pair being rotated through 90 degrees with respect to one another, so that a pair of ports 3 and 4 symmetrically located with respect to one of the axes of symmetry is coupled to a pair of ports 1 and 3, symmetrically located with respect to the other axis of symmetry. Reference is made to further filters constructed by using a conductively bounded transmission line with discontinuities introduced at locations determined by the different field distributions for the different transmission modes, or employing the different response of gyromagnetic materials to oppositely rotating circularly polarized waves together with an array of longitudinally spaced half waveplates.

Said deviation responsive means comprises a rib 37 on the beam 5 which when the latter becomes tilted, due to say piston 2 advancing faster than piston 1, and opens spill valve 32 and closes spill valve 31. Each bypass line 29, 30 also includes a solenoid operated dump valve 41, 42 upstream of the spill valves and which when the beam operates limit switches 51, 52 are suddenly opened to connect the associated branch line and hence supply line to reservoir 11 and thereby arrest motion of the associated piston. Each discharge valve 64a, 64, e.g. valve 64, Fig. 3, comprises a spring- biased spool 71 having a peripheral groove 73, lateral bores 75 and an axial bore 74 provided with an orifice 76 which when the piston 63 of the main spill valve is moved to the open piston results in spool 71 being moved to the right and by-pass line 30 being connected through groove 73 to reservoir 11. The housing of the discharge valve 64 may also include a relief valve 78. Downward movement of pistons 1, 2, is initiated by moving coupled solenoid spool valves 17, 18 in lines 15, 16 to the left.

An amplifier has the first stage, for example, T 2 , T 3 , coupled to the second stage, comprising complementary transistors T 4 , T 5  in series by means of an intermediate circuit including a constant current transistor T 1 , complementary transistors T 6 , T 7  identical with T 4 , T 5  and each having its base and collector connected, the transistors T 6 , T 7  being connected to T 4 , T 5  bases and to a pair of voltage-defining devices, such as diodes D 3 , D 4 . The first stage, as described, is a differential amplifier. The load Z is connected to the common emitters of T 4 , T 5 , and the amplifier input is applied to T 2 , the bases of T 1  and T 3  being held at reference levels. Further transistors T 8 , T 9  may be connected in series with T 4 , T 5  respectively. The diode-connected transistors T 6 , T 7  maintain under all conditions, including variable temperature, a voltage between the bases of output transistors T 4 , T 5  which balances the sum of the emitter base voltages of the transistors T 4 , T 5 . In this way thermal runaway is prevented. Moreover, power dissipation in the output stage is largely concentrated in T 8 , T 9  whose base voltages are controlled respectively by diodes D 4 , D 3  and whose currents are effectively controlled by transistors T 4 , T 5 , so preventing thermal runaway conditions from developing in T 8 , T 9 . A resistor R enables the quiescent currents in T 6 , T 7  and T 4 , T 5  to be exactly balanced.

Abstract: 1278448 Palm-print recognition C H LIPTON M EBERT and N G ALTMAN 3 Dec 1969 [3 Dec 1968] 59120/69 Heading G4R A palm-print reader forms and scans an image of a palm-print pattern to produce a signal which is converted into a code number. The palm is placed on the hypotenuse of a prism in a position defined by pins and a microswitch. Light internally reflected from the hypotenuse is imaged on to a rotating disc having a radial slit backed by a photodetector to produce a waveform each leading and trailing edge of which gives a pulse in a train which is correlated with a similar pulse train obtained by comparing successive numbers from a card with a clockdriven counter. Each pulse from the comparison occurs on equality with one of the numbers, and also serves to gate the counter reading via a register to a computer, for example. Changeover of a switch results in the gating being controlled by each leading and trailing edge pulse from the palm in position, in which case the gated counter readings are used for preparing a card for use as above. Applications to employee time keeping, identity checking (cheque cashing), and security checking are described. The computer may be used for a security status check on the person identified by the succession of gated counter readings.
