Title: Improvements in controlling mechanism for windows, doors, panels and like sliding elements
Inventor: PERNETTA CHARLES
IPC: E05D13/00
Filed: 1953-11-20
Abstract: 723,056. Sliding window opening and closing apparatus. BECKETT, LAYCOCK & WATKINSON, Ltd. Nov. 20, 1953 [Aug. 21, 1952], No. 21061/52. Class 20 (3). [Also in Group XXXIV] Sliding panels, e.g. windows, doors, &c., are operated, or balanced, by means of a coil spring 17 which is secured to a bobbin 16 rotatably mounted by a pin 15 on a bracket 14 secured to the underside of the lower frame member 11, e.g. of a vertically sliding window 10 of a vehicle, the uncoiled portion 18 of the spring being anchored at 58 to a fixed rail 13 and preferably constrained within a channel guide member, not shown. In an alternative arrangement, Fig. 4, the spring 20 is freely housed within a box 28 secured to the lower frame member 11, the open side of the box being directed downwards and the uncoiled portion of the spring being led through a slot in the side of the box. An absorbent lubricating pad 25 is provided on the edge of the slot to wipe the uncoiled portion of the spring as it is led therethrough, the casing being similarly lined to engage the outer surface of the body of the coil. In a modification, Fig. 3, a pad 29 is mounted to ensure continuous contact with the coil as it winds and unwinds, a friction locking device 30, 31 being also provided. For heavy panels a plurality of springs can be mounted side by side in a single casing or they can be so arranged that the unwound portions of the coils are superposed upon one another. When the arrangement is adapted for sliding doors, the coil body is housed in a casing at one end of the track, the free end of the coil being secured to a hanger for the door. In further modifications the coil or coils are mounted in side pillars, or in the lintels, of the panel frames, the free ends of the spring, or springs, being attached to the frames. The springs can also be mounted in boxes, as shown in Fig. 4, one at each lower corner of the panel, with their axes normal to the plane of the panel.

Abstract: 755,897. Dry plate rectifiers. WESTING- HOUSE AIR BRAKE CO. July 20, 1954 [Aug. 12, 1953], No. 21088/54. Class 37. In Figs. 1 and 2 a nylon yoke or frame 2 having arcuate sides 4 encloses a rectifier disc 8 and U-shaped phosphor bronze contact members 6 are seated over the flat end walls 3 of frame 2 in resilient pressure contact with the disc 8. Each contact member 6 has a bowed inner leg 6b and a shorter outer leg 6a to which is connected a lead-in wire 7. The sub-assembly, Fig. 2, is coated with varnish &c. and inserted in a brass tube 9 which is then filled with an insulating potting compound 10. The inner diameter of tube 9 is substantially equal to the diameter of the arcuate side walls 4. The assembly in Fig. 3 comprises a bowed spring 11 between two rectifier discs 8 and further discs 8 may similarly be accommodated by adding springs 11. The invention provides miniature assemblies, e.g. using <SP>1</SP>/ 16  inch diameter rectifier discs. The relatively large surface area of the contact members 6 effectively dissipates the heat produced when soldering the lead-in wire 7 into an external circuit. Short lead-in wires 7 may therefore be used. The discs 8 may be of copper oxide or selenium.

Filed: 1978-05-22
Abstract: In the case of the conductor, a plurality of conductor wires (20) which are composed of superconductor material and metal which is electrically normally conductive at the operating temperature of the superconductor material are twisted or braided to form a flat conductor element (1). In order to increase the current carrying capacity, a plurality of flat conductor elements (1 to 19) are combined in the manner of a transposed conductor. The individual conductor wires (20) of the conductor elements (1 to 19) in this case consist of a matrix of metal which is electrically normally conductive and of filament wires which are supported therein and consist of superconductor material. Conductors of such construction are suitable particularly for magnetic coils which are subjected to variable fields. <IMAGE>

Title: Tensioned webs
IPC: H01P1/163
Filed: 1972-05-05
Abstract: 1416331 Circular-electric mode waveguides POST OFFICE 3 Aug 1973 [5 May 1972] 21130/72 Heading H1W The TE 11  and other undesired modes are suppressed in a circular waveguide intended for propagation of the TE 01  mode by means of a resistive radial web 4 inserted under tension into the waveguide by a method involving elastic deformation of the latter. For this purpose, the waveguide is divided longitudinally into halves 1, 2 of semi-circular section. The web 4, which consists of a dielectric sheet with resistive layer, is attached to the mating surfaces 3 of section 1 by means of, e.g. a cyanacrylate adhesive whilst the section is under radial compression, so that after the adhesive has set and the compression forces have been removed, the resilience of the section produces lateral tension in the web. The upper section 2 is placed in position and the sections held together by a closely fitting sleeve 5. Preferably, the base (non-resistive) surface of the web is attached to the section 1. Compression may also be applied to the section 2. The sleeve 5 may extend beyond the sections 1, 2 and may serve as a locating means for additional lengths of waveguide. Conductive continuity between the sections 1, 2 may be obtained by providing one of them with teeth which penetrate the web or by providing edges of the web with holes which are filled with conductive material. The web may be apertured and has a resistance equal to the wave impedance of the unwanted mode. It is stated that the web may support gyromagnetic material.

Abstract: 989,950. Making bags; seaming non-metallic sheet material; cutting webs. GRISWOLD CORPORATION (1961) Ltd. Aug. 14, 1962 [June 13, 1961], No. 21281/61. Headings B5D and B5K. [Also in Divisions B6 and B8] A machine for making, filling and sealing bags forms a tube from a web, seals the tube transversely and severs it to provide the bags, feeds the bags into grippers which carry them to opening means and beneath a filling head and finally seals and discharges the packages. The bags may be gusseted. The web W, which may be a laminate of aluminium foil and sulphite paper, is fed from a braked roll 21 by rollers 29, 31 operating in response to the rise of a dancer roller 43 which contacts a switch to set them in motion. The dancer roller is raised by the intermittent tube feed described below. The web is reversed and passes round stationary shaping plates 93 to former means 65, 81, Fig. 10. It is drawn intermittently through the cylinder 81 and over the element 65 by gripper means comprising fingers 115, 115a on a piston rod 102 and gripper pads 117, 119. In forming the tube, the web margins are brought face to face and the upstanding fin then laid flat by a slot 83 and resilient finger 84 in the cylinder 81, a normally lowered heat sealing element 163 sealing the overlap, Figs. 10, 15. The gripper pads 117, 119 are reciprocated in unison with the fingers 115, 115a by a piston rod 107a, and pneumatic means 129 presses them on the web tube against the fingers during the forward (e.g. to the right as in Figs. 1, 10) stroke. Plates 151, spread the tube and rails 114 projecting into slots 79 and between the plates from side gussets. The machine is arranged to stop when the pad 163 is manually raised. The completed tube passes through sealing and severing means E comprising transversely divided upper and lower jaws 213, 215 and 217 respectively, Fig. 19. The lower jaw is resiliently mounted relative to a member 179 and a cutter 181 mounted on the member is projected through the jaw by pneumatic means 191. The part 213 of the upper jaw forms a heat seal and the part 215 merely grips the tube. The upper jaw is lowered by pneumatic means through a yoke 188 and rod 193. The bags are finally filled and sealed (see Division B 8).

Title: Procedure for measuring group delay-time
IPC: H04B3/46
Filed: 1965-05-20
Abstract: 1, 115, 064. Group delay measurement. TAVKOZLESI KUTATO INTEZET. May 20, 1965 [May 20, 1964], No.21470/65. Heading G1U. In an arrangement for measuring group delay time, a varied frequency is transmitted through the network under test and at the receiver is passed into two channels in one of which it is delayed. The outputs from the two channels are compared in phase, and since the delay has the effect of giving one output a frequency shift relative to the other at any given instant (since the frequency of the input to the system is continuously changing) this phase difference represents the group delay at each instant. Signals from a fixed frequency generator 1 and a wobbulator 2 are mixed at 3 and passed to the network X under test. The output from X is converted to an I. F. frequency at 5 by mixing with a signal from a generator 6 varied in accordance with the wobbulater 2. The I. F. signal is passed to a buffer circuit 7 which passes it directly to a phase difference measuring circuit 8 and also to a delay 9 whose output provides the other input to the circuit 8. The output from the phase difference circuit 8 passes via a channel switch 9 to be displayed on an oscillograph 14 which is calibrated by frequency markers derived through a channel 4. Calibration of the system is achieved through a separate phase adjusting, measuring and delay system 10, 11, 12.

Abstract: 1,126,944. Helmets; ear protectors. L. P. FRIEDER. 13 May, 1966 [2 June, 1965], No. 21474/66. Heading A3V. [Also in Divisions A5 and H4] A sound attenuating device comprises an ear cup adapted to receive an ear of a wearer and having an aperture spaced from the rim of the cup, a valve movable between a closed position withinthe aperture and an open position completely outside the aperture, and means connecting the valve to the ear cup in all positions of the valve. As illustrated in Fig. 2, an ear cup 14 comprises a wall 30 from the rim of which extends an annular flange 33 to which is fixed a ring 34 of resilient material, for example sponge rubber, having a cover 35 of pliant material, for example leather; extending radially about the wall of the cup are annular flanges 36 and 37 which retain an endless cord 38 about which are looped straps, such as 15, by means of which the cup may be secured by screws, such as 17, to a helmet. Disposed within the cup is resilient sound absorbing material in the form of a body 40 and a layer 42 which are shaped to define a pocket 41 for receiving telephonic equipment, for example a receiver, and a passageway 43 for providing communication from the outside of the cup via an aperture 49 formed in the wall of the cup to a space 32 defined within the cup by the sound absorbing material. The aperture is formed in a boss 48 which is integral with the wall of the cup and which provides a valve seat 47 formed by the cylindrical surface 49a defining the aperture and by planar annular boss surfaces 49b and 49c which surround the aperture. As illustrated in Fig. 9, the valve includes a valve plug 46 formed of a resilient non- porous material, for example a plastics material, and comprising a drum 46a to one end of which is joined a flange 46b, the drum being adapted to be received in the aperture in the wall of the cup and the flange being adapted to engage the outer surface of the cup in the closed position of the valve. The flange is formed with the first tab 50 forming a flexible hinge, which connects the valve to the ear cup, and with a diametrically opposed second tab 51 forming graspable means for moving the valve between the open and closed positions; to facilitate grasping, the rib 51a may project transversely from the surface of the second tab. A screen, for example a fine wire mesh, may extend across the inner end of the aperture to prevent ingress of foreign objects into the cup when the valve is open. The drum defines a closed chamber filled with a gas, a liquid or a particulate solid material, preferably a fluent sound absorbing material, for example lead oxide. Two constructions of the drum and associated flange are fully described and illustrated in the Specification.
