IPC: B63B1/38
Filed: 1981-07-01
Abstract: A marine vessel comprises a hull (2), two chamber wall members (4) which project downwardly from the hull and extend longitudinally of the vessel, the bottom of the hull and the two wall members defining a chamber below the water line of the vessel, and air supply means (14, 16, 18) for supplying air under pressure to the chamber, the arrangement being such that in use the air forms an air layer in said chamber between the water and the bottom of the hull and the air is at least in part prevented from escape laterally of the vessel by the two wall members. One or more longitudinal dividers (11) and transverse ridges (10) or circles divide the chamber into sub-chambers, fed by respective cross-ducts.

Title: Method of operating storage tubes to compensate for positive ion charging
IPC: H01J31/18
Filed: 1981-08-04
Abstract: In a method of operating a storage tube in bistable mode, after a positive charge pattern has been written on the freshly erased tube storage surface by bombarding the latter with electrons at a potential above the first cross-over potential, a continuous train of "maintain" voltage pulse signals is applied to the tube storage mesh structure backing electrode, the pulse voltage being of such amplitude that, during the pulse, written areas of the storage surface are above, and unwritten areas are below, the first cross-over potential; wherein in operation there is eventually achieved a dynamically stable condition of both written and unwritten areas in which the effect of positive ion charging is substantially or totally cancelled by the effect of flood beam charging.

Title: Multi-processor office system complex
Inventor: JOHNSON MIZE
IPC: G06F13/37
Filed: 1982-02-24
Abstract: A multi-processor system formed by a plurality of intelligent Processing nodes (100, 101, 102, 103) interconnected by one or more transmission lines (15) to form a shared resource cluster provides two levels of modularity which facilitate system design and growth requirements. Within each node a synchronous exchange bus (25) interconnects processors (30) in any combination up to a maximum total number of units, all microprocessor controlled except for global memory and the like. Each microprocessor controlled unit (350) connected to the synchronous exchange bus includes random access memory (302) which is functionally divided into a first portion (302) for storing instructions and data for the on-board processor and a second portion acting as a global memory (43) accessible by other processor controlled units on the bus. Memory address assignment for the global memory portion of each unit memory is stored in the unit in a register (106) which is accessible by other units, so that the system can reconfigure memory address assignments by re-writing the memory address assignment in the on-board register via the bus or directly from the on-board processor. An I/O or slot address (R<u1>u) is assigned to each board as it is plugged into the bus identification lines and this I/O or slot address is used to access the board for memory address assignment.

Title: A sand casting mould apparatus having gas flow passages
Inventor: STEINEMANN DANIEL
IPC: B22C17/00
Filed: 1983-05-17
Abstract: The apparatus comprises a model (6), supporting a model plate (3), a carrier (1), and a molding frame (5) surrounding the model (6) and resting on the carrier (1) thereby defining a volume for receiving molding sand to form a casting mold. Gas flow gaps (9) are formed at the corners formed by the junctions of the model (6) and model plate (3), and gaps (10a) are formed around the edges of the model plate (3) near the molding frame (5). The gaps either admit CO2 hardening gas, or a mould release gas, to the mould, but preferably conduct gas from the mould e.g. during mould compaction by pre-pressurised or by exothermically pressurised gas, eliminating back-pressure and trapped gas pockets in the mold, facilitating formation of edge and corner sharpness of the mold and thence of the ultimate casting. The gaps can be connected to channels (11, 12, 13, 14, 15, 22, 23) permitting venting to the atmosphere or to a vacuum container, or merely accumulation and the creation of special pressure change conditions within the mold volume. <IMAGE>

Title: Electromechanical short interval timer
Inventor: FLAIG HANS
IPC: G04F3/06
Filed: 1984-01-19
Abstract: An electromechanical short interval timer has an actuating dial 1 which can be manually rotated from a rest position 11 to establish a time-elapse period. An electric motor 9 returns the dial 1 to its rest position 11. A timing circuit 12 delivers electric pulses to drive the motor 9. A frequency selector switch is connected to or within the timing circuit whereby the pulse frequency can be varied. In this way, the time elapse period which is set by a given amount of dial rotation can be varied in a simplified manner. The dial 1 activates a signal emitter before reaching its rest position 11, and simultaneously activates a timer circuit to continue returning the dial to its rest position. The dial engages a movable stop at both ends of its 360 degree travel stroke which assumes that the dial travels exactly 360 degrees. <IMAGE>

Title: Preventing surge in an axial flow compressor
Inventor: LUCAS RUPERT MORTON
IPC: F04D27/02
Filed: 1984-05-19
Abstract: In axial flow compressors of gas turbine engines it is well known to use either an air bleed valve 34 or a compressor casing treatment to improve the performance of the compressor. Air bleed valves act to keep the working line of the compressor close to the surge line. The casing treatment, which usually consists of one or more grooves 28 in the internal cylindrical surfaces adjacent the tips of a stage of upstream blades 22, acts to raise the compression ratio at which the rotor stalls. This invention combines the use of the bleed valve 34 with the grooves 28 to allow the bleed valve setting point to be reduced and ensure the bleed valve is closed at low power settings. <IMAGE>
