Title: Improvements in gramophone disc records and methods of manufacture thereof
IPC: G11B3/70
Filed: 1928-09-19
Abstract: 321,014. Thornton, J. E. Sept. 19, 1928. Addition to 319,038. Compound sheet materials. - A gramophone record of the kind described in the parent Specification, comprising a paper or like core or base having attached thereto one or more layers of chemically-hardened glue or gelatine in which sound-grooves are impressed, is made by coating or impregnating the paper with adhesive colloid, and applying thereto, by heat and pressure, the face layer or layers as preformed sheets of the colloid material. Preferably glue is used as the adhesive, and sheet gelatine for the outer face or faces. A chemical hardener is, during the process of manufacture, diffused throughout the whole mass. The base or core consists of a very thick sheet of absorbent paper or thin board, and after coating or soaking it in a stiff solution of glue or gelatine, containing if required a small proportion of a flexing agent such as molasses or glycerine, it is dried. The coated base is then moistened with a chemical hardening agent such as formalin or alum, and a sheet of the colloid in which the record grooves are subsequently impressed is laid in contact with each side of the base (or, for a single-sided record, on one side only), and attached by applying heat and pressure. Alternatively, instead of applying the hardening agent separately, as described above, it may be mixed with the colloid adhesive during the coating or impregnating. In either case, attachment of the face layer or layers is effected before the chemical action of the hardener upon the adhesive has taken place. A further modification consists in incorporating a hardening agent with the outer colloid sheets before they are applied to the base or core. The composite sheet is dried by exposure to warm air, free from dust, and is finally impressed with sound-grooves in the usual way when the face layers have hardened sufficiently. A flexing agent such as sugar or molasses may be mixed with the outer gelatine sheets, or may be provided both in these and in the adhesive with which the core is coated. Instead of making the record blanks in single sheets, they may be formed in continuous webs, the constituent layers being cemented by pressure between heated rollers. The impression of sound-grooves on separate sheet blanks may be effected simultaneously with the uniting process. The core may embody a layer of linen or the like, as described in Specification 820,963. Barium sulphate, paris white, chalk, or colouring pigments &c., may be incorporated with the colloid of the central core, or in the outer layers. Specification 319,062 is referred to.

Patent GB-824651-A (GB)
Title: Improvements in or relating to traffic indicating or control apparatus
IPC: G08G1/081
Filed: 1955-09-20
Abstract: 824,651. Automatic traffic control. EASTERN INDUSTRIES Inc. Sept. 20, 1955 [Sept. 21, 1954], No. 26912/55. Drawings to Specification. Class 118 (2). [Also in Group XL (c)] An analogue computer is used to measure traffic density and in accordance with the measurement to switch a traffic controller on to an appropriate operating cycle. Each traffic detector when operated by a vehicle generates a pulse which is shaped by a thermionic valve circuit, passed through an isolating diode to a common pulse shaper and triggers a flip-flop circuit which gives one pulse for each two input pulses (or one for one if only one detector is switched in). The output pulse is again shaped and operates a one shot timed multivibrator. The period of the multivibrator is variable and preset in accordance with the number of detectors in operation and the traffic engineer's judgment of road conditions. The pulses from the multivibrator are accumulated in a C.R. circuit with a constant leak and thus a voltage is developed over the capacitor which is proportional to " instantaneous density " aggregated over a running period of 20 seconds. This varying voltage is applied via a cathode follower to a second aggregating capacitor with a time constant variable between 1 and 9 minutes. The circuit is arranged through a diode and a preset resistance, two diodes in opposition being wired so that one or the other resistance is in circuit, depending on whether the instantaneous voltage is rising or falling. By this means the C.R. rate of the circuit may be different for each of these conditions. The average control voltage thus obtained is applied to five parallel valves each with a different cut-off point and having switching relays in their anodes (see Group XL (c)). The valves are arranged with a different cut-off point when non-conducting so that hunting is prevented. The switching relays are used to effect the operating cycle change over. U.S.A. Specifications 2,288,601 and 2,594,276 are referred to.

Title: Improvements in or relating to microwave transmission systems
IPC: H01P1/02
Filed: 1958-08-22
Abstract: 845,253. Waveguides. WESTERN ELECTRIC CO. Inc. Aug. 22, 1958 [Aug. 29, 1957], No. 27043/58. Class 40(8). Losses due to attenuatior and generation of un wanted modes in a curved circular waveguide design ed for the H 01  mode are minimized by the use of a dielectric liner 28 made of dielectric e.g. polyethylene or polystyrene tape. The tape is first wrapped in a spiral around a mandrel 29. The wrapped mandrel is inserted in the guide and given an anti-clockwise twist to tighten the tape on the mandrel. The mandrel is then withdrawn and the direction of twist reversed to press the tape against the waveguide wall. The Specification draws a distinction between curvatures of radius greater than 200a<SP>2</SP> feet, designated "bends", and those of radius less than this quantity, designated "elbows" (a is the radius of the waveguide in inches). It is stated that losses in bends are mainly due to attenuation of the H 01  mode and a thickness of dielectric liner for minimum attenuation is given as a function of the guide radius, the curvature andthe dielectric constant of the liner. It is stated that the optimum thickness is independent of frequency. Losses in elbows are stated to be due to generation of the H 11 , H 12  and E 11  modes. By making the dielectric liner thicker the phase difference between the H 01  and H 11  modes may be increased, but at the same time the phase difference between the H 01  and H 12  modes is decreased. An optimum thickness may be achieved for which conversion losses to the E 11  and H 12  modes are equal and conversion to the H 11  mode is small. This optimum thickness is given as a function of guide radius, the dielectric constant of the liner, the propagation constants of the various modes and the curvature coupling coefficients between them.

Title: Frequency modulated relaxation oscillator
IPC: H03K3/281
Filed: 1963-07-09
Abstract: 1,044,384. Frequency modulation; pulse modulation systems. NORTHERN ELECTRIC CO. Ltd. July 9, 1963 [July 9, 1962], No. 27111/63. Headings H4L and H3R. In a relaxation oscillator, Fig. 2a, one side of a reactive element, e.g. a capacitor 10, is charged over a resistor 11 at a variable rate depending on a modulating voltage V m  (in series with a D.C. supply E) until a voltage - V t  is reached when a circuit 13 triggers a switch 15 to connect the charged side of the capacitor to a fixed voltage e.g. earth, and the modulation input to the other side of the capacitor 10, so that the other side of capacitor 10 is charged over resistor 12 until, at voltage - V t , a similar trigger circuit 14 reverses the switch 15. The capacitor voltage is thus a triangular waveform and oscillates between a value + V t  and the triggering value - V t , Fig. 2b (not shown). The output pulses frequency modulated by the source V m  may be used for producing an F.M. signalling sub-carrier. The capacitor may be charged over a resistor alternately to opposite polarities by one or a pair of D.C. sources and trigger in turn at voltages + V t  and - V t  respective trigger circuits which actuate a switch reversing the polarity of the D.C. input voltage E (and modulation V m ) charging the capacitor. An F.M. square waveform may be derived from the integrator circuit formed by the capacitor and resistor. The circuits 13, 14, Fig. 5, may be Schmitt transistor trigger circuits producing pulses of opposite polarity at their transitions which operate through a transistor bi-stable circuit T5, T6 to open and close in turn the emitter/collector paths of two switch transistors T7, T8 (switch 15) connected to the sides A, B of the capacitor 10. Resistors in series with each side of the capacitor 10, Fig. 7a (not shown), may be used to linearize the frequency modulation for different modulation frequencies. In Fig. 8 the reactive element is an inductor 95. Two series connected tunnel diodes 73, 74 are switched to different voltage states at times determined by the peaks and minima of a symmetrical sawtooth voltage input to their junction 77, of variable slope dependent on the modulation V m  so that rectangular waves are generated of variable width and applied through an emitter follower T 9  and amplifier T 10  to a double diode limiter circuit 72, 92 which modulates the rectangular wave amplitudes to values determined by the modulation V m . This output is then integrated by the series resistor inductor (or capacitor) circuit 94, 95, to form the input sawtooth waves of variable slope to point 77. A tunnel diode 79 in the emitter circuit of T 9  shortens the output pulse rise time.

Abstract: 789,589. Angular bending. GENERAL ELECTRIC CO. Sept. 5, 1956 [Sept. 6, 1955], No. 27176/56. Class 83 (4). A portable power-operated bending tool comprises a power-actuated clamping means, a fixed abutment spaced from the clamping means and a power-driven abutment movable about the clamping means substantially in a plane containing the fixed abutment and the clamping means. Rectangular sectioned wire 4 is placed in the bending tool so that a roller 26, fixed in a tool housing 19, and a roller 12, carried by a sleeve 10, 11 mounted to rotate about a fixed block 1 in the housing 19, lie to one side of the wire and a rod 2, axially movable in the block 1 and carrying a clamp plate 3, lies to the other side of the wire. A button 22<SP>1</SP> of a three-way valve 22 is then depressed to allow compressed air through an inlet conduit 24 to the lower end of a cylinder 6, in which is movable a piston 5 secured to the rod 2, and to allow compressed air through a conduit 25 to a motor, e.g. an airdriven vane type turbine motor, in a housing 20 mounted on the housing 19. Thus simultaneously the clamp-plate 3 moves up to clamp the wire 4 against the block 1 and the sleeve 10 is rotated by the motor, through gearing, to move the roller 12 about the rod 2 to bend the wire therearound. To remove the bent wire, the roller 12 is backed off therefrom by operating control means 21 to reverse the motor and the button 221 is released to allow a spring 7 on the rod 2 to disengage the plate 3 from the wire. The roller 12 and clamp-plate 3 may be driven electrically or by steam.
