Title: Propulsion device comprising a block of propellant provided with a central duct of varying section
Inventor: HIVERT MICHEL
IPC: F02K9/10
Filed: 1990-05-25
Abstract: The invention concerns a propulsion device for acceleration of a self-propelled engine, such as a missile or a rocket. The propulsion device comprises a body (1) equipped with a nozzle (2) and a block of propellant (3) having a longitudinal central duct (4) of varying section. The block of propellant comprises a downstream part (5) having a cylindrical duct (6) which has a circular section whose diameter is less than two thirds of the diameter of the throat of the nozzle (2) and an upstream part (7). The duct (8) of this upstream part (7) has a diameter which exceeds the diameter of the duct (6) of the downstream part and which is less than the diameter of the throat of the nozzle (2). The duct (8) is connected to the duct (6) of the downstream part by a frustro-conical portion (9). The length of this upstream part (7) is on the one hand between two and four times the external diameter of the block of propellant and on the other hand less than the length of the downstream part (5), the total length of the block of propellant being more than six times the external diameter of the block of propellant. <IMAGE>

Title: Drier
Inventor: RATTY WILLIAM LEONARD
IPC: A47K10/48
Filed: 1990-10-16
Abstract: A drier is made up of a body having a slot allowing access by an object, such as a hand H, to be dried in a working volume 15 within the body; a plenum chamber 17 located at least part way around a periphery of the working volume; an air blade or knife slot orifice 20 communicating the plenum chamber with the periphery of the working volume; an air blower; and ducting 21 linking the plenum chamber to an outlet from the blower. The blower, ducting and slot orifice are combined to enable sufficient pressure energy to be applied to air in the plenum chamber on the upstream side of the slot orifice such that it is displaced through the slot and the pressure energy is substantially converted into kinetic energy with air speeds of the order of 800 km/hour about 10 mm downstream of the slot in the working volume. <IMAGE>

Title: Autofill valve
Inventor: GREENHOUGH JAMES MICHAEL
IPC: B63C11/08
Filed: 1991-09-11
Abstract: An air control valve for a buoyancy control diving jacket G having a manually connected inlet hose A for the air comprises a body with an inlet B, an unrestricted outlet to an instrument console E, a second outlet leading a non-return valve G allowing the air to exit via D to an emergency air reservoir, and a third outlet manually controlled by a valve F allowing air from the reservoir to flow into and inflate the jacket. The Autofill valve prevents a diver commencing his dive with an emergency air reservoir that may be empty or only part filled. The valve will also maintain high pressure air in the emergency air reservoir while the air in the main air cylinder is being depleted. The valve also enables the instrument console to be controlled so that it is easily interrogated by the diver or his companion and its potential for snagging is considerably reduced. <IMAGE>
Patent GB-2263458-A (GB)
Title: Spacecraft.
Inventor: GOULD ROBERT ANTHONY
IPC: B64G1/00
Filed: 1992-01-09
Abstract: A spacecraft has a box-like body with a plan form of a Pentagon, Hexagon, Heptagon, Octagon, Nonagon, Decagon. These all have parallel longitudinal sides, with each of them to be as a box with a lid to hinge open. Triangular wings are fitted. Reflected versions, meaning the floors are at a depth below the wings as well as above and these versions are as five floor, more like spaceship shape, which can be as Pentagon, Hexagon, Heptagon, Octagon, Nonagon, Decagon. The lids open as hinged from one of the parallel sides or one end. They have a rudder attached on a high tail on the back top of the lids. Flaps on the back part of the wings give pitch control. The jet rockets are rectangular which they curve to a point at the tops, the rockets power the craft which they turn in the upright position or to lay flat on a vertical when if they was to fly, as vertical take-off in flight, the crafts would have reverse thrust in the jets to sit down on the stands at the bottoms. The other versions are as the same designs but with two floors above the wings, and no floors below the wings. In this case a rectangular jet with a rounded front is fixed into the wings along side the 5-10 shapes, then each of them have jet stands which fix under the wings to fold up or down. In the down position the jets would blast away lifting the craft high into the air. When the rectangular jets take over thrust the jet stands die out then fold away under the wings. They would then have reverse thrust for landing. <IMAGE>

Title: Method of forming a ceramic mold for metal casting
Inventor: URAM STUART Z
IPC: B22C9/02
Filed: 1992-03-18
Abstract: A method of forming a ceramic mold (14) for producing metal castings including the step of injection molding individual mold sections from a slurry of ceramic particles and a binder, is disclosed. Each of the individual green sections of the mold (12) is low temperature fired to remove therefrom a major portion of the binder while leaving therein a minor portion of the binder sufficient to afford structural strength thereto, and the individual mold sections are inspected and assembled together to form the mold. Finally, the mold (14) is high temperature fired to complete the removal of the binder. Optionally, the individual mold sections may be assembled together to form the mold assembly before the first low temperature firing. <IMAGE>

Title: Magnetic tape cassette slack limiter
Inventor: GEBEKE CHARLES DENNIS
IPC: G11B15/43
Filed: 1992-06-11
Abstract: Magnetic tape 26 is guided by pins 30, 28. Slack limiter 34 is a post spaced from pin 30 to create a gap (width specified) through which the tape passes. When the supply reel 22 is not driven, the post 34 prevents the tape from spilling out of the cassette by forming loop 26A. Post 34 need not be round (Fig. 2, not shown), and may be moulded integral with the base and/or cover, or may be a separate item received in bosses in the base or cover. A part may be installed between pin 30 and post 34 to maintain gap width. <IMAGE>
Patent GB-2257324-A (GB)
Title: Navigation system
Inventor: STEELE STEPHEN JOHN
IPC: G01S1/70
Filed: 1992-09-11
Abstract: Systems for navigating moving bodies, particularly systems based on the detection of rotating beams of radiation, often require complex or expensive equipment, such as a number of laser modules or a specially laid floor over which the body can move. The invention overcomes this requirement by providing a navigation system, and a method of navigating a body in which two beams of the same frequency, rotating at equal and opposite angular velocities and distinguishable in form, are produced by a single radiation source and detected by at least three spaced apart sensors on the body being navigated. The outputs of the sensors are used to calculate the angular and radial position of the body relative to the radiation source. The invention is of particular use in navigating moving cameras, for instance on a studio set.
