Title: Broadband spectrum analyzer for testing jammers and the like
IPC: G01R23/00
Filed: 1960-10-13
Abstract: 900,707. Frequency spectrum analysis. GENERAL MILLS Inc. Oct. 13, 1960 [Oct. 15, 1959], No. 35105/60. Class 37. [Also in Group XL (c)] A broadband spectrum analyser, particularly for testing " jammers " on aircraft, comprises a resonant cavity 16, swept by a vane 24 so that an output pulse will be obtained from the cavity each time it is tuned to the frequency of the transmitter, the results being displayed on an oscilloscope, and a movable frequency marker being also provided on the oscilloscope by means including a disc 88 which rotates with the shaft 26 carrying vane 24. The output from detector 30 is applied to a pulse amplifier 32 and a signal proportional to the amplitude of the output from 32 (and therefore to power) to the vertical deflection plates 48 of the C.R.O. via an amplifier 40, stretching circuit 42 and adder 46. A signal corresponding to the detected pulse frequency is applied to the horizontal C.R.O. plates 52 from amplifier 32 via amplifier 58, a gated amplifier and trigger generator 66, " time demodulator " 74 and stretching circuit 84. The " time demodulator " 74 relates the frequency output from 16 to the time position of vane 24 in cavity 16 so that a signal will be located correctly along the horizontal axis. The cavity 16 sweeps through the complete tuning range twice for each rotation of shaft 26 since vane 24 produces a pulse both as it enters and leaves the cavity and, in order to prevent ambiguity, only one of the sweeps is used. This is achieved by gating out any input to demodulator 74 not lying within an interval (so that no pulse occurring outside the time interval is displayed) predetermined by a multivibrator 96 which is triggered via an amplifier 94 from a magnetic pick-up 92 coacting with a slug 90 in disc 88, the arrangement being such that a pulse is generated in pick-up 92 each time vane 24 is at its maximum insertion. The adjustable frequency marker referred to above is generated by an adjustable magnetic pick-up 112 associated with a second slug 110 (at a different radial location from 90), the pulse from which corresponds to a particular cavity frequency depending on the position of pick-up 112. The frequency is indicated on dial 118. The output from pick-up 112 is connected to a pulse forming circuit 120 through a multivibrator 122 and integrator 124 as a sawtooth waveform to the vertical plates of the C.R.O. The input to the horizontal plates (for the frequency marker) is applied from circuit 120 via the second input 62 of amplifier 58. A counter 138 enabled for only a fixed time interval indicates the FM sweep rate of the jammer.

Title: Improvements in or relating to presses
IPC: B30B9/30
Filed: 1960-10-13
Abstract: 952,190. Presses. COW & GATE Ltd., G. M. ROBERTSON, and G. K. CHARLES. Sept. 29, 1961 [Oct. 13, 1960], No. 35187/60. Heading B5F. [Also in Division B8] A press applies pressure to at least two pairs of opposite faces of a body by a plurality of spaced pressure pads at each face, binding bands being passed between the pads when the body is compressed. Rotatable shafts 21, 22 on frame members 11, 12 each carry three L-shaped levers 41, 42 having pressure pads 46, 47, Fig. 2, whilst a rotatable shaft 20 on frame member 10 has three levers 60 with pads 61, Fig. 1. The fourth frame member 13 rigidly carries three levers 50 with pads 51, Figs. 1, 2. A base member 120-127, Fig. 4, is fixed to rod 103 of a pneumatic or hydraulic ram 100 on whose casing 101, Figs. 1, 2, the frame members are attached by members 15, 16, 17, 18; a channelled member 134, 135 rests on the base member. In operation, with the ram extended a bottom panel and a cheese block, for example, are placed on member 134, 135; the ram is lowered and members 134, 135 come to rest on members 10, 11, 12, 13, side, end and top panels being then inserted. Rotation of a handle 73 and shaft 70, Fig. 1, moves levers 41, 42 inwardly via flange 77 and levers 81-84, Fig. 2, until the side panels abut the end, top and bottom panels. Levers 60 are then moved inwardly via shaft 70, cam surface 95, follower 96, and lever 97, Figs. 1, 3; a panel 140 then engages a notch in shaft flange 76 to prevent reversal of the shaft 70. Ram 100 is then extended to move the base upwardly. Metal bands are then passed through channel member 134, 135 and fastened around the container. The ram pressure is then released and lowers rod 103 which releases panel 140 allowing rotation of handle 73 to relieve pressure on the side and end panels. The ram is fully extended to remove the packaged cheese. The press in Figs, 6-9, not shown, has a rectangular frame with two sets of movable pads which apply pressure only to side and end panels, the pads being operated by two rams, one of which is supplied with pressure fluid through a restriction to initiate movement of one set of pads before the other. One frame side is pivotably mounted on another side to allow sideways insertion of a body to be compressed. Specification 937,441 is referred to.

Abstract: 893,684. Electrical insulating tapes; yarns and threads. MIDLAND SILICONES Ltd. Oct. 19, 1959 [Dec. 4, 1958], No. 35329/59. Drawings to Specification. Classes 120(3) and 142(4) [Also in Groups VIII and XXXVI] An electrical insulating tape, particularly for use in a taping machine, is shrunk before or after coating with silicone or other rubber so that it can stretch when wrapped round corners or in partly-overlapping layers. In one embodiment, all the weft and half the warp consists of three-ply glass yarns and the remainder of the warp consists of three-ply yarns wholly or partly of heatshrinkable thermoplastic material, for example two plies of glass and one of the shrinkable material or one ply of glass and two plies containing both glass and the shrinkable material; the glass may be replaced by silica or asbestos or by previously-shrunk yarns of nylon, polyethylene terephthalate, polyacrylonitrile, or a copolymer of vinyl and vinylidene chlorides. The tape is coated with the rubber on one or each side and the shrinking may occur when it is heated to cure the rubber, in which case the rubber coating wrinkles when the tape is in the unstretched state. The tape may be applied to one face of a triangular extrusion of silicone rubber, preferably of the self-adhesive kind described in Specification 868,041 [Group XXXVI]. In another embodiment, the shrinkable material is in the weft of a wide fabric which is coated with rubber and then cut into strips weftwise. The warp is entirely of three-ply glass yarns and the weft is of three-ply yarns, some of which are entirely glass and some entirely vinyl-chloride-vinylidene-chloride copolymer monofil; or the weft yarns may consist of two singles of glass plied with one monofil of the copolymer, or of two such plied yarns alternating with two yarns entirely of glass. Nylon, polyethylene terephthalate, polyacrylonitrile, or organo-polysiloxane may be substituted for the copolymer.

The discharge nozzle of a container 1 (Fig. 1) comprises a nozzle member 3 slidably mounted in a tubular guide 8 projecting from a wall 2 of the container. At one end, the nozzle member 3 is provided with a flange 6 on which a compression spring 20 bears, the other end of the spring bearing on a frusto-conical member 9 fixed to the inside of the container. The member 9 is provided with perforations 11 to allow the passage of liquid in the container into the nozzle member 3, an annular diaphragm 12 of rubberized fabric preventing liquid passing between the nozzle member 3 and the guide 8. A vent tube 16 is attached to the nozzle member 3, the latter being sealed by a valve member 17 connected to a stem 18 the other end of which is attached to the member 9 at 19. The container is filled by means of the cap 5, and to empty the contents into a tank, for instance, the container is inverted as shown and a flange 7 on the nozzle member 3 is pressed into engagement with the lip of the tank aperture. Thus the nozzle member 3 moves inwards against the force of the spring 20 and permits the flow of liquid past the valve member 17, the displaced air in the tank passing up the vent tube 16 into the container until the level of liquid in the tank closes the tube 16, whereupon no further liquid flows. In a second embodiment, (Fig. 4, not shown), the discharge nozzle is attached by screwthreads (32) to a tubular member (31) extending from the wall of the container. To fill the container, the discharge nozzle is removed and the liquid enters through the tubular member (31). To remove the contents, the container is inverted and a flange (49) is pressed against the tank aperture, as before. The nozzle member (44) then moves inwardly against the force of the spring (45) to allow the passage of the liquid past the valve member (48). A vent tube (46) is provided.
