Title: Improvements in or relating to the making of hollow articles by metal spraying
IPC: C23C4/18
Filed: 1968-07-02
Abstract: 1,215,184. Making hollow-ware; casting processes; mould-coating materials; casting composite articles. CHELTON (FORMING) Ltd., and I. C. G. BERRY. 2 Oct., 1969 [2 July, 1968], No. 31582/68. Headings B3A and B3F. A method of making a hollow article by metal spraying on to a former comprises coating the former with graphite suspended in a highly volatile liquid, evaporating the liquid, coating with a cellulose lacquer, coating with polyvinyl alcohol and then spraying with the metal. Instead of graphite a silicone may be used and the cellulose lacquer may be replaced by a plating "stopping-off" solution. Usually a thin layer of metal is sprayed initially and the article is built up by further spraying, casting or the application of other materials, e.g. reinforced plastics materials. The former is then removed.

Title: Data processing system
IPC: G06F13/16
Filed: 1969-06-25
Abstract: 1,223,809. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 25 June, 1969 [11 July, 1968], No. 31975/69. Heading G4A. A data processing system includes a plurality of processors and a store and means whereby each processor can specify to the store a "store", "fetch" or "information - transmission - toanother - processor" instruction to be performed by the store, the store being provided with the identity of a recipient processor whenever a "fetch" or "information - transmission" instruction is specified and retaining this identity until the store transmits the information specified by the instruction. A bussing mechanism considers each processor and each of a plurality of storage modules in turn (first processor, then first storage module, then second processor, the second storage module, &c.) to detect if it wishes to transfer a word to a storage module (in the case of a processor) or a processor (in the case of a storage module), transfer being between a memory data register in the storage module, via a local register in the bussing mechanism, and either a send register or a receive register in the processor. If the word is from a processor it specifies (a) operation, (b) storage address, including module, (c) data, (d) destination processor, field (d) not being used in the case of a store operation. The word, if from a storage module, has fields (b), (c), (d) only. The registers above each hold all of the word as transferred, though only the data field of the memory data register is read into or from the store itself. The memory data register also holds a "ready" bit to indicate if transfer is required, and the receive register also has a "filled" bit. Each processor includes a request array for buffering words to be transferred out, addressed by an in counter and an out counter, and a fetch array addressed by a counter for receiving data fetched from storage. Each location of the fetch array has a data field, an address field loaded from the relevant word in the request array, and a "valid" and an "in use" bit, data received in the receive register being placed into the location in the fetch array which contains an address agreeing with the address in the receive register (and has the "in use" bit at 1 and the "valid" bit a 0), or into a message array addressed by a counter if no address matches (the message array thus receiving data transferred from other processors as distinct from data fetched from storage at the request of its own processor, which goes into the fetch array). In the processor-to-processor transmission via the memory data register of a storage module, storage in the store itself is not involved, but as a modification it could be. A message word received by a processor from another processor could be executed as an instruction without altering the instruction counter (unless the word is a branch instruction) or could be treated as the address field of an execute instruction or the immediate data field of a supervisor call instruction. Part of the word might determine how the rest of the word should be treated.

Title: Improvements relating to colour television systems and receivers therefor
IPC: H04N9/455
Filed: 1964-11-26
Abstract: 1,092,455. Colour television. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Nov. 26, 1964 [March 13, 1964, No. 32114/67. Divided out of 1,092,454. Heading H4F. In a P.A.L. system the colour synchronizing " burst " which is transmitted in the intervals between lines consists of two quadraturephase components, one of which assumes the same fixed phase in all lines and the other of which alternates in sign in successive lines. The two components 103, 104 may be transmitted in succession, Fig. 1, or may be transmitted simultaneously, Fig. 2, whereby the resultant signal 7, 7<SP>1</SP> alternates in phase Œ45 degrees with reference to the fixed phase 103. In a receiver for use in the system, Fig. 5, a transittime demodulator 3, 4, 16 is used to separate the I<SP>1</SP> and Q<SP>1</SP> components of the chrominance subcarrier signals and also functions to separate the components of the " burst " signal such that the fixed phase components 103 alone appear in the Q<SP>1</SP> signal channel and the alternating phase components 104 alone appear in the I<SP>1</SP> signal channel. The subcarrier and " burst " components are separated by appropriately timed gates 5, 6, 115, 122, the subcarrier components passing to demodulators 20, 24 and the " burst " components being applied to synchronize oscillators 9, 117 which supply reference signals to the corresponding demodulators. Oscillator 9 is synchronized at the fixed phase of component 103, but oscillator 117 is caused to alternate in phase in agreement with component 104 so that demodulator 24 is operated in the appropriate phase in successive lines to cause the output to be + I<SP>1</SP> despite the alternation of the subcarrier input in accordance with P.A.L. method of operation. The " burst " components function to establish the oscillators in the correct phase at the beginning of a line whilst synchronism during a line is maintained by the I<SP>1</SP> and Q<SP>1</SP> subcarrier components which are applied to control the oscillators via a frequency doubling circuit as described in Specification 1,070,193. The successive components of Fig. 1 may be separated without a delay line system (as in Fig. 5) by the use of appropriately timed gate circuits. The fixed phase component 103 may then be used to synchronize a quartz crystal oscillator which synchronizes a second oscillator via a phase shifter which is switched at line frequency in response to the alternating phase component 104. Reference is also made to the use of the " bursts " of Figs. 1 or 2 to synchronize a quartz crystal oscillator so that it is established at a phase midway between the " burst " phases of two successive line intervals. The production of a synchronizing signal as shown in Fig. 5, by adding components in successive lines with aid of a delay line, forms the subject of Specification 1,092,454.

Abstract: 629,163. Shoes with detachable uppen. JONES, O., and DANIELIUS, E. Dec. 5, 1947, No. 32195. [Class 17 (ii)] Retaining means on the edge of a shoe upper are engaged in a detachable manner by longitudinally moving them along a groove which extends around the top or sides of a sole member. In the form shown, grooves run on opposite sides of the sole 1 and have mouths 2a, 3a which lead to enlarged portions 2b, 3b into which may be slid enlargements 5, 6 on the opposite side edges of the upper 4, so that the two shoe parts 1, 4 are prevented from separation except by longitudinal movement of the enlargements 5 in the portions 2b, 3b of the grooves. Hooks 7a on the upper may be engaged with the sole to prevent disengagement. In a further modification, the sole may be in two parts both of which have open grooves so that when the two parts are assembled together closed grooves into which retaining means may be slid are formed on both sides of the sole. In a still further modification, the grooves may have metal reinforcing members, especially where the sole is of leather, and the retaining member on the upper may be discontinuous and formed by separate pieces which may be interlocked with equally spaced separate portions of a metal reinforcing member. Where a shoe upper is closed at the heel, the two parts may be constructed so as to be fastened together after the upper has been engaged with the sole.
