Title: Improvements in or relating to radio communication systems
IPC: G01S13/87
Filed: 1941-04-11
Abstract: 566,785. Wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., and ULLRICH, E. H. April 11, 1941, No. 4850. [Class 40 (v)] [Also in Group XXXVI] A signal is isolated from the echoes due to reflection in the upper atmosphere by transmitting the signal on two or more wavelengths, and at the receiver changing the received waves to the same wavelength by heterodyning, and then combining the resulting waves in suitable phase relation. Either the direct signal or the echoes may be made available for reception, or they may be used in combination if time delay networks are interposed. The system may be used in locating objects by reflection. The receiving-circuit shown comprises filters 2, 3 passing respectively the two wavelengths #1, #2. The former passes directly to a transformer 12, and the latter is heterodyned by a source 6 through a phase-adjuster 5 to produce a wavelength #1 which is selected by a filter 7 and passed to a transformer 13. Each transformer has two secondary coils which are crossconnected to produce an adding effect in one detector 8 and a subtracting effect in the other detector 10. The Specification shows that by suitable choice of the frequency difference in relation to the time lag of the echo signal behind the direct signal, these signals are separately available at the output of the detectors 8, 10. As shown, they are combined in the telephones 11, the direct signal being suitably delayed by a network 9. The Specification discusses the case when more than two wavelengths are employed, and indicates that frequency-modulated transmissions may be used. For purposes of adjustment pulse signals from the transmitter may be received on a cathode-ray indicator to show the time-lag between the direct signal and the echoes, and thus enable optimum frequencies to be found. Specification 296,827, [Class 40 (v)], is referred to.
Patent GB-1600657-A (GB)
Title: Disc brake
IPC: F16D55/02
Filed: 1978-02-07
Abstract: The disc brake has brake anchor plates for accepting the braking torque, which brake anchor plates are connected to brake-lining carriers (24). Provided on the outer periphery of a pull-action application device (26, 28) are partially annular noses (30), behind which there engage cut-outs (31) of brake-lining carriers (24). The noses (30) are axially displaceable and, during their axial displacement, they release the brake-lining carriers (24). The replacement of the brake linings (25) is thus simpler, even when the disc surface is used to the full. <IMAGE>

Abstract: 555,018. Controlling aircraft. FAIREY AVIATION CO., Ltd., and DARE, W. J. April 15, 1942, No. 4962. [Class 4] [Also in Group XXIV] Consists in linkwork for moving a member angularly by a member moving in a substantially rectilinear path and in such manner that equal increments of movements from a neutral position along the rectilinear path will produce progressively increasing increments of movement of the angularly movable member. Conversely, if the latter member be moved through equal increments, the rectilinearly movable member will be moved by progressively decreasing increments. The invention is particularly applicable as a control for elevators, ailerons and other pivotally mounted aerofoil surfaces. The member a is to be moved angularly by the member b which moves substantially along the straight path shown in broken lines. Attached to member a is a connecting-rod c which together with the member b is pivoted at g to an intermediate point in a link f. This link is pivoted at its ends h, j to the free ends of links k, m the other ends of which are pivoted at fixed points n, o. The neutral positions are indicated at O and the increments of movement on either side of these positions by lu - - 7u, and 1d - - 7d, for the members b, and 11u - - 17u and 11d - - 17d for the member a.

Abstract: 194,679. Conley Foil Co., (Assignees of Conley, E. J.). March 10, 1922, [Convention date]. Paper and like bags, making; materials, special, for linings.- Relates to a method of uniting sheets of foil applicable to the formation of packages such as are described in Specification 173,783, and consists in forming a package composed of relatively thin tin foil and a wrapping of paper by folding the foil*upon itself and folding the paper around it, a heated sealing instrument being applied adjacent the edges, and sealing the paper along its overlapping edges. As shown in Fig. 3, a rectangular sheet 1 - - 4 of foil is placed on an irregularly-shaped sheet 5 - - 12 of paper. The sheets are folded about the line 6, 11 with the foil inside, and the ends are folded inwards about the lines 17, 18 and 19, 20. This brings four thicknesses of foil together at the folds F<1>, Fig. 1, and leaves two flaps P<1> of paper on the outside. The flaps are secured as by gluing and a sealing instrument is applied to the folds so that fusion of the foil is effected by heat conducted through the paper. In another form, the double fold is dispensed with and a single layer of paper overlies two thicknesses of foil. In another form, sheets F, P, Fig. 12, of foil and paper respectivelv and of the same size and shape are folded as shown. The overlapping edge of foil and paper is then folded between the outstanding flap of paper and the remainder. The outer flap of paper is glued and the seam fused by conducted heat. The ends of the tube thus formed may be folded up and the corners 43, 44 folded in and fused in the same way. A cigar &c. may be inserted and the top closed in the same way. The foil used is preferably of a thickness of less than 3/1000".

Title: Improvements relating to the handling of biscuits
Inventor: MORRISON ROBERT HENRY
IPC: B65B23/14
Filed: 1965-02-08
Abstract: 1,111,619. Feeding biscuits in counted batches. BAKER PERKINS Ltd. 9 May, 1965 [8 Feb., 1965], No. 5402/65. Headings B8A, B8C and B8S. After a predetermined number of biscuits has been delivered from the bottom of a shoot 1 (Fig. 2), by flights 5, the spacing between the flights and the bottom biscuit is altered to interrupt delivery. In one form, a follower roller 14 controlling the position of each flight as it passes under the magazine 1 is deflected from a cam surface 22 which permits it to deliver biscuits, to an alternative surface 30 which results in no delivery. The movement of the follower 14 is effected by a bell-crank 25, 26 operated by a solenoid 28, and the follower and flight are held in their deflected position by a toggle link 17. Interruption of delivery, at the proper count, is effected by one of several cams operating control switches and selected by manuallyoperated switches. Delivery is also interrupted if the biscuits in the magazine fall below a predetermined level, and the device detecting this preferably operates at a curved portion of the magazine where the slope of the biscuits depends on the rate at which they are supplied. In an alternative arrangement (Fig. 3, not shown), the path of the flights 5 is fixed, and either the magazine 1, or the base of the magazine, is moved, under the control of solenoid 28, to clear the path of the flights when the count is complete. The biscuits may be delivered directly to a horizontal conveyer (9), (Fig. 1, not shown), or may be carried by steps (75), (Fig. 4, not shown), on a rotor carrying the flights 5 to a conveyer 77 where they are arranged in horizontal stacks. A check-weigher may automatically vary the number of biscuits counted into each batch.

Filed: 1953-02-27
Abstract: 744,766. Thermionic valves. RADIO CORPORATION OF AMERICA. Feb. 27, 1953 [March 13, 1952], No. 5624/53. Class 39 (1). A cathode shield for an electron power tube for use at high frequencies having a multifilament cathode comprises two metallic members 61, 65, one of which is apertured and which are welded together round their edges forming a hollow space. The ends of the filaments are bunched around a central plug 59 and are arc-welded in the aperture of the shield. The shield is preferably made of molybdenum and the upper member may be frusto-conical in shape. This shield prevents grid and anode current due to electron emission from the top of the cathode, whilst enabling the control grid to be open at the top, thus reducing grid capacity and lowering the operating temperature of the grid. The filaments are arranged to form a cylindrical cage. The upper ends are bent radially inwards to engage the shield while the lower ends are supported alternately from plates 69 and 71 by means of clamps 51 to supports 55a and 55b respectively. These clamps are merely pinched on during assembly and it is stated that the filaments sinter themselves to the supports during normal tube processing but may be easily detached for replacement. A channel beamforming section 79 is placed behind each filament to direct the electron streams away from the grid support rods 81 and 33. The beam channels are maintained at filament potential, the lower end of each channel being clipped to a filament support 55a. The grids are mounted by means of screws, for ease of dismantling, to the conical metallic parts 5 and 9, which are so shaped to prevent heating of the insulating sections 15a, 15b. and 17 by radiation from the cathode or by electron bombardment. The anode carries a flange 29 which prevents overheating of the insulating section 19 as described in Specification 744,769.
