Filed: 1969-11-20
Abstract: 1325000 Digital transmission; phase shift systems PLESSEY CO Ltd 12 Nov 1970 [20 Nov 1969] 56833/69 Heading H4P  A phase shift system has data defined by the relationship between pairs derived from three or more consecutive signal elements by comparison of phase difference between, for example a first and second element with the phase difference between the second and third &c. It is stated that phase changes over at least three elements due to a Doppler shift, provided this is reasonably constant, are cancelled by the double phase comparison. In a, triple element arrangement described, the incoming signal is applied to three transmission lines 12-14, elements on line 13, [14] being delayed by 1, [2] element period[s]. Adjacent pairs of elements are phase compared at 15, 116 and the result passed to a level comparator 17 giving a mark or space output from lines 18, 19. In a double element arrangement, Fig. 5 (not shown) only two lines (20, 21) and one delay (23) are provided at the input with a further delay element (24) in the level comparator input. The delays may be shift registers or any conventional form of phase and level comparators may be used. It is envisaged in the Specification that higher order differential phase shift systems than the triple element system disclosed with reference to Fig. 4 may be constructed. It is assumed that unwanted phase shifts extend one more signal element more [e.g. four, than the number of primary phase comparisons [e.g. three].

Filed: 1970-10-15
Abstract: 1332111 Information retrieval SHELL-MEX & BP Ltd 15 Oct 1970 [15 Sept 1969] 45338/69 Heading G4C In a data store in which the stored data is organized in pages under a number of keywords a page containing data which is to be accessed is located using electrical signals representing successive characters of a keyword which are analyzed and used to generate a further signal indicative of the required page. A keyboard unit 1 is provided to enable an operator to generate signals indicative of the data which is to be accessed. The signals consist of two groups the first of which relate to a data category, e.g. clerical staff in a business organization, and the second to name details which may include index letters, e.g. the first three, to specify the name in sufficient detail for the relevant page in the store to be located. As described three stores (directories) are provided each having a corresponding page selector selected by a coded combination of category and name detail signals. If after the first index letter has been typed the relevant page can be determined, i.e. if all the names in the selected directory beginning with that first index letter appear on a single page, the letter counter 7 is reset and a page identifying signal is generated. However if names beginning with the first index letter appear on more than one page an indication is passed to the operator indicating that a further index letter is required and this further letter is handled by letter counter 7a and a corresponding section in the page selector. The process repeats until the required page is selected from a combination of the signals representing the index letters used. Two page selectors 6 are described. In the first the selector is divided into a number of sections one for each index letter, each section comprising a matrix array of gates interconnected to generate signals in accordance with the organization of the store. Each section is interconnected with the succeeding section so that the signals representing a number of index letters may be combined to select the required page. In the second a register stores the signals representing three index letters are sequentially compared with coded data accessed from, e.g. a magnetic tape and representing the keywords associated with successive pages of the store until a match is obtained. The specification described the page selectors and the remaining components in the system in some detail and states that the store pages may be formed of microfilm frames or of tracks on a magnetic drum. The accessed pages may be presented visually or audibly to the operator so that selection of the required name may be made. Details relating to that name may then be accessed audibly or visually.

Abstract: 1347986 Driving vehicle auxiliaries BRITISH LEYLAND TRUCK & BUS DIVISION Ltd 4 Oct 1972 [12 Oct 1971] 47339/71 Heading B7H [Also in Division F2] A gas turbine vehicle is equipped with a pneumatic brake system A, the brakes being operated by a pedal-operated valve B which acts to connect the brakes to a storage bottle 1; the gas turbine engine 2 has its compressor 3 arranged to supply to the storage bottle 1 the quantity of air required for the brakes and a separate compressor 4, driven by the engine 2, boosts the pressure of this air to the extent necessary for operating the brake system A. As shown in Fig. 1 the compressor 4 is supplied with air from the compressor 3 via a pipe 5, a check valve 6 and a cooler 7. The high pressure air from compressor 4 is delivered through a line to an unloader valve 10 which direct the air to bottle 1 or back to compressor 3 via a line 12, and air from compressor 4 also enters a non- return valve 14, which may be contained within the same casing as valve 10. When the pressure in bottle 1 reaches a predetermined value a bellows (15) in valve 10, see Fig. 1A, overcomes a compression spring (16) to open valve 10 to pass air from line 9 to line 12 and back to the engine 2. The pressure in line 9 is thus reduced and valve 14 closes to prevent further delivery to bottle 1 until the pressure therein falls to a value sufficient to cause valve 10 to close, whereon valve 14 will open again under increasing pressure. In the embodiment of Figs. 2, 2A excess pressure in bottle 1 will open a valve 17 and act via a pipe 18 to move a control piston 20 in a delivery valve 21 to cut off pipe 6 from a duct 24 and connect the duct 24 to a vent 26 to thereby cut off air supply from the engine. An inlet valve 27 is also opened by the excess pressure in pipe 18 until sufficient excess pressure is vented.
