Title: Spread spectrum linear fm communications system
IPC: H04B1/69
Filed: 1972-11-28
Abstract: 1368678 Radio signalling SPERRY RAND CORP 28 Nov 1972 [20 Dec 1971] 54852/72 Heading H4L  A pulse compression communication system comprises a transmitter including a source of triggering pulses, a generator for providing under the control of the triggering pulses a plurality of frequency-swept carrier oscillations which produce a plurality of signals within a limited timefrequency region, each signal having a different time versus frequency characteristic, and means which transmit the plurality of frequency-swept signals, and a receiver including an antenna responsive to the transmitted signals and a pulse compression processor for providing a plurality of output pulses in which each output pulse corresponds to a selected one of the plurality of transmitted signals. The frequency swept may be varied for equal duration pulses or the pulse duration may be varied for equal frequency sweeps, or a combination of these arrangements may be used. Additional signals may be provided by using both positive and negative frequency sweeps. In a synchronized system, first a short duration low time-bandwidth synchronizing signal is transmitted and using the same large time-bandwidth of fixed frequency slope the centre frequency of subsequent transmitted signals is moved backwards and forwards in time so that the output signals occupy different time slots. To increase the number of signals transmitted in the synchronized system, additional sinusoidal frequency modulation may be imposed on the linear frequency sweep, which produces paired sideband signals which are time displaced about a central portion in accordance with the frequency used. By varying the amplitude of the additional frequencies further signals may be obtained. In the synchronized system, the receiver is in a hunting mode until the sync signal is received and a single dispersive filter handles all the channels, additional decoding circuits following the filter. In one embodiment Fig. 5 (not shown), one signal is transmitted at a time, the signal characteristics forming an address signal. In a second embodiment, Fig. 12 (not shown), using the synchronized mode with additional frequency modulation, two signals may be transmitted at a time, one using a positive frequency sweep and the other an orthogonal negative sweep. In this type different FM slopes may be used to convey message information or may be used as addresses for single receivers or groups of receivers.

Title: A method of and apparatus for continuously casting thin metal sections, such as ribbon, wire or like sections
Inventor: MORITZ GUNTHER
IPC: B22D11/045

Abstract: 1,236,291. Continuous casting. VEREIN- 1GTE ALUMINIUM-WERKE A.G. 11 Nov., I969 [12 Nov., 1968], No. 55211/69. Heading B3F. A continuous casting mould comprises a chamber 6 in which a thin cast strip 10 is shaped and indirectly cooled by coolant flowing in a duct 8 and a further chamber 11 in which the cast strip is directly cooled by impinging coolant issuing from bores 8. The second chamber 11 includes a constriction 15 and bores 17 leading to air-boxes 18. In operation this construction produces a reduced pressure behind the constriction 15, to suck air through bores 17 into the cooling water jets from bores 8 and thereby reduce the cooling effect of the water jets upon the casting. In addition, the reduced pressure extends along the walls of the cavity 6 into meniscal cavities 19 formed at the end of the molten metal introduction pipe 3. Lubricant from passages 20 is sucked by the reduced pressure through a wadding 21. To vary the cooling properties of the direct coolant stream both air and coolant flow can be varied, and a highly thermally conducting gas can replace air in the boxes 18.

Filed: 1974-12-27
Abstract: 1487861 Magnetic domain devices INTERNATIONAL BUSINESS MACHINES CORP 27 Dec 1974 [1 Feb 1974] 55911/74 Heading H3B Mutually repellant, variable size elements (especially magnetic bubbles) are propagated in a closed loop channel by selectively holding an element and changing the size of an element to cause interaction between the elements in the channel effective to propagate the elements when the held one is released. In Fig. 1 the channel is formed by ion-implanting, conductor patterns, grooves, or permalloy strip or discrete element overlays. A current pulse to conductor 26 expands bubbles labelled 1, 2, 3 to fill the space defined by the conductor and squash the others together. Bubble 33 is held outside the conductor by the current until it ceases whereupon the bubbles 31, 32, 33 enter the conductor loop as bubbles 1, 2, 3 contract. The current is at 100-500 kHz and may be accompanied by a bias field of 20 Oe possibly with a 60 Hz modulating field of 5 Oe. Bubbles may be nucleated within the channel by local laser heating or may be transferred laterally into it from Y and I-bar overlays or a conductor shift register by parallel conductors (A, B, C, Figs. 4, 6, 7, not shown), the shift register being operated by multiphase interlaced conductors (Fig. 8, not shown). Alternatively a lattice of bubbles may be formed by a large in-plane field and those in the channel contracted to a single strip whilst others are added by a conductor loop or by splitting; or an array of strip domains formed transverse to the conductor loop by an in plane field and the conductor pulsed to cause splitting.

Abstract: 1,119,953. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 22 Dec., 1966 [27 Dec., 1965], No. 57378/66. Heading H4K. In a national network comprising for example switching centres or offices W . . . Z interconnected by groups of trunks 1 . . . 5, the routing of calls is effected from a register at the originating office under the control of a programmer which contains information as to the availability of the inter-office trunks and supplies the addresses to be forwarded to each tandem office. The order of preference for the routing of a call between W and Z is indicated in Fig. 1. The layout in Fig. 2 assumes that such a call is routed through tandem offices X, Y. A programmer 27 receives information from a so-called status processor 54 which records the availability of trunks outgoing from W and obtains information concerning the tandem trunks over an independent network. The originating register 24 interrogates the programmer 27 through a translator 26. If, in spite of the routing supplied by the programmer, an all-trunks-busy is found at a tandem office, the connection is released, and the register 24 again interrogates the programmer for a fresh route. Calls are graded as high priority and low priority and certain of the trunks are allocated primarily to high priority traffic. An indication is given to the status processor, Fig. 3 (not shown), when all such trunks outgoing from an office are occupied with high priority traffic. As regards the other trunks, indications are given when a high percentage are in use and when all are occupied. Conditions such as carrier failure and power failure are also notified.

Abstract: 1,167,922. Radar displays. PLESSEY CO. Ltd. 27 Dec., 1967 [28 Dec., 1966],No. 58016/66. Heading H4D. The Specification describes a radar display system, wherein the presentation of responses from the antenna rotating in azimuth is converted from a PPI display to a type B display, with targets appearing dark against a bright background, and with the facility for interrupting the raster and adding labels &c. to the type B display. The invention is said to be useful in a secondary surveillance radar wherein height &c. information, obtained from interrogating an aircraft, may be written on the display opposite its response and viewed in bright control tower ambient lighting. To facilitate exact relocation of the interrupted raster scan, the scan deflection signals are produced digitally in staircase form, clock pulses being counted in respective line and from digital counters, the outputs thereof being fed to the frame and line coils via digital to analogue converters, and gate means being provided in the clock feed to the counters for stopping the counting during the writing of the label and temporarily resetting counters to zero whereby the spot is returned to the centre of the display screen for commencement of the label writing. To overcome the high-voltage requirements normally caused by the fly-back in a T.V. raster, no fly-back is used, and alternative line scans are in opposite directions.

Further cam means gives a movement proportional to " gravity-drop " which is a function of the total time and a measure of the tangent elevation to be applied to the gun.
