Inventor: HOLMES THOMAS JOSEPH
IPC: G05D1/08
Filed: 2023-06-26
Abstract: Est présenté un système de contrôle d’attitude pour un satellite qui peut déterminer des valeurs de temps de fonctionnement pour des propulseurs de contrôle d’attitude sans utiliser de détecteurs de variation d’attitude, tels que ceux basés sur des gyroscopes. Les systèmes de contrôle d’attitude utilisent les valeurs d’attitude d’un suiveur stellaire pour déterminer à la fois des valeurs d’ajustement d’attitude et des valeurs de variation d’ajustement d’attitude directement à partir des valeurs de suiveur stellaire, où le traitement est réalisé à l’aide de quaternions. À partir des valeurs d’ajustement d’attitude et des valeurs de variation d’ajustement d’attitude, un ensemble de valeurs de temps de fonctionnement des propulseurs sont déterminées.

Title: Medicament containing disulphiram
IPC: A61K9/50
Filed: 1969-03-21
Abstract: The inconveniences accompanying the use of disulphiram (I, Et2N. CS. S. SC. NEt2) in sufficiently large doses to hinder the normal metabolism of alcohol in the body to pyruvic acid, CO2, etc. are overcome by coating the particles of I with up to 20 layers of material which produces its slow release in the stomach. The coating is done by repeated steepings in a soln. or suspension of the coating material with intermediate dryings. Suitable coating materials are lactose, starch, stearic acid, shellac, and film-forming polymerisates e.g. polyvinylpyrrolidone.

Title: Short crust pastry cases suitable for moist fillings
IPC: A21D13/08
Filed: 1969-04-23
Abstract: Method of making pastry cases, particularly of short crust pastry, in which an edible wafer is inserted between the case and the filling so that moisture from the filling cannot be transferred into the pastry. When the pastry is made the sugar is added, after or concurrently with the fluor, to a premixture of all the other ingredients; the final mixture is poured or spread on to a wafer in a baking tin, and cooked. Because the sugar is added after or together with the flour, it remains for a while in crystalline form without dissolving. During cooking, the sugar dissolves partly in the fat and forms a caramel which soaks into the wafer. After cooking, the wafer is securely united to the pastry with no gaps.

Title: Cpd glass fibre nozzle plate - with charge glass sealed joints
IPC: C03B37/083
Filed: 1972-05-19
Abstract: The plate forms the bottom of a resistance melting vessel and comprises ceramic nozzle elements consisting of silica-, alumina- or magnesite base material, the abutting joints of which are closed by glass from the melt which solidifies and crystallises out in the gaps between the nozzle elements.

Title: Cooling system using liq. as coolant - contg helical coils, one inside the other
IPC: F28D7/02
Filed: 1973-03-09
Abstract: System consists of two helical coils, kept concentric by uniformly spaced supports. Refrigerant liq. flows through the inner coil. Cooling liq. is pumped from a tank through the annular space between the coils to the external circuit which can be open or closed. In the case of a closed circuit, the pressure is maintained constant at a predetermined level by a vertical branch, fitted between the coil outlet and a control cock, the height of the branch determining the pressure. A sight glass enables observation that the vertical pipe is full. In the case of open circuits, the coolant liq. returning to the tank after performing the duty flows through a filler and a decanter contg. descaling salts. Liquid level is maintained constant in the tank by overflows and by a float controller and valve connected to e.g. town water supply. The double helical coil ensures uniform efficient heat-transfer and economical fabrication and the system ensures uniform flow in the external circuit.

Title: Vaulted floor container production method - has plate edges welded to intermediary ring and curvature achieved by pressure
IPC: B23K9/028
Filed: 1973-12-28
Abstract: Method for the production of containers with vaulted floors, in which the edges of the plates intended to construct the container floor are set up, and then each two plates with set up edges are connected to a hollow body. Inside the hollow body a pressure is produced which causes the plates to arch outwards. The hollow body then divides into two vaulted floors, and finally each floor is welded to a cover part of the container. The set-up edges of the plates are cut away at the point where the curvature process begins, and the union of the two plates is achieved by means of an intermediary ring, the edges of which are welded to the edges of the plates. The division of the hollow body occurs at the level of the intermediary ring.

Title: Starting device for free piston engine - uses slide valve to reduce and then increase pressure of air cushion
IPC: F02B71/02
Filed: 1974-03-15
Abstract: The free piston engine has a main piston with a combustion chamber, a compressor piston formed by a local increase in diameter of the main piston, and an air cushion. The air cushion is surrounded by a reservoir of compressed air. When the slide valve is operated by pressing a plunger air from the reservoir is delivered to a pump, causing the piston to rise and reduce the pressure of the air cushion. This reduction of pressure causes the piston to move, opening a valve which in turn opens a further valve, allowing high pressure air to enter the cylinder and return the piston and so start the engine.
