Patent GB-1102591-A (GB)
Title: Power transmission system for a gas turbine engine
Inventor: WICKMAN AXEL CHARLES
IPC: F02C7/36
Filed: 1964-05-22
Abstract: 1,102,591. Gas-turbine engines. AUTO TRANSMISSIONS Ltd. May 12, 1965 [May 22, 1964; Aug.28, 1964], Nos. 21152/64 and 35306/64. Heading F1G. A gas turbine road vehicle power plant, similar to that described in Specification 842, 163, comprises a turbine 10 driving a compressor 11 and a separate turbine 19 driving a power output shaft 18. The drive from turbine 10 is transmitted to the compressor by a hollow shaft 13 connected to the planet carrier 12 of a step-up epicyclic gearing A. The planet gears 14 drive an annulus gear 15 integral with the compressor. A unidirectional clutch 30 prevents turbine 10 from over-running the compressor. The sun gear 16 of the epicyclic gearing A transmits power to a drive shaft 17 running inside shaft 13. Shaft 17 and the output shaft 18 of turbine 19 are coupled through a step-down epicyclic gearing B to a common power output shaft 29 driving the road wheels. Brake bands 26, 28 are engaged for forward or reverse drive respectively. Sun gear 16 is mounted on a sleeve 31 carrying a brake disc 33 within a fixed casing 34. Braking of disc 33 by pads 35 prevents power being transmitted from sun gear 16 to drive shaft 17 and thus prevents the vehicle from creeping forward when the engine is idling. A pump 36 supplies pressure fluid to brake pads 35 when a leak-off valve 39 is closed by a solenoid 41, the operation of which is initiated by the automatic closing of switches 43, 44 when the engine throttle 45 is closed and the road speed drops below a predetermined low value. A unidirectional clutch 32 allows rotation of shaft 17 with movement of the vehicle when sun gear 16 is braked. A further unidirectional clutch 53 enables shaft 17 to drive compressor 11 when the vehicle over-runs, so as to prevent stalling of the compressor. In a modification, Fig. 2 (not shown) drive shaft (17) runs parallel with the output shaft (18) from turbine 19 and the two shafts (17, 18) are geared through a non- epicyclic reduction system (B) to the common output shaft (29). The operation of the braking system for the sun gears (16) is the same as described above. The modified plant is similar to that described in Specification 1, 017, 714 and may include a reverse drive by modifying the reduction gearing (B) as described in Specification 1, 001, 639.

Title: Addressing system for computer data store
IPC: G11C15/00
Filed: 1964-05-26
Abstract: 1,022,794. Electric digital data-storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 26, 1964 [June 3, 1963], No. 21794/64. Addition to 1,018,915. Heading G4C. In a data storage system, a data string may be addressed from either its beginning or the address of the latest portion of data in the string to be accessed, for the purpose of searching through the string, the address of the said latest portion being itself stored and being continually up-dated, to enable this to be done. In the parent Specification, hierarchicallyorganized data strings of variable field length are stored in a main memory in such a way that only one level-identifier character is stored in a given machine word, the level-identifier characters being present in the strings to delineate the various hierarchical levels (e.g. paragraph, sentence, phrase). The locations of the level identifiers are specified by occurrence marks (ONE bits) in corresponding locations in auxiliary stores (one such store per hierarchical level). A given portion of data is accessed by an instruction such as, for example, " third phrase of the second sentence of the fourth paragraph before/ after address X," (X being the beginning address of a data string), by counting occurrence marks in the " paragraph " auxiliary store starting from address X until four (in the above example) have been counted and then counting marks in the " sentence " auxiliary store starting from the address thus reached &c. In the present Specification, the above mode of searching constitutes a first option (" simple mode ") but two others are provided, the option required being specified in the instruction for each hierarchical level separately. " Current mode " starts the search (in the given level) at a " current " address relating to that string and stored in the data string. When the required address (in that level) is reached, it replaces the previous current address. " Set mode " is the same as " simple mode " except that when the required address is reached, it is stored in the " current " address location. Full conventional circuitry to achieve the above is shown and described. It is mentioned that more than one current address location may be provided in each data string to enable sequential portions of a given data string to be read out in different predetermined sequences automatically. It is shown, for example, how to read out (e.g. in matrix multiplication) the first and first (sic) numbers of a sequence to enable them to be multiplied together, then the second and fourth, then the third and seventh, using one current address location for obtaining the first number of each pair and another current address location for the second, using " set mode " for the first step and " current mode " for the others. The invention may, of course, be used with fixed field length data strings.

The counter is pre-set as shown with 0 set into positions 0-5 and 1 into positions 6-9, and upon receiving 2<SP>5</SP> clock pulses, a "1" count in position 5 is taken via shaping circuits 19-20 to trigger the converter 3 to commence the discharge of the capacitor. The counter counts a further 32 clock pulses and resets to zero and counts on again until the end of the square pulse indicates the capacitor is discharged. In this event, since the bi-stable 15 is unaffected by the negative wave-front, the signal is taken to negative AND gate 21 and is applied to switch bi-stable 15 off after a delay of 4 clock pulses introduced at 22, 23.
