Title: Self-cooling pressurised beverage in disposable cans - includes gaseous refrigerant which is released when can is opened
Inventor: WIRTH ARNO H
IPC: F25D3/10
Filed: 1973-08-31
Abstract: Cooler for beverages in pressure tight containers uses refrigerant, which is gaseous in the container. The beverage container has a releasable closure which covers a smaller opening for exit of the refrigerant, that causes a drop in temp. when the press. drops, and a larger opening for exit of the pressurised liquid, e.g. beer or lemonade in disposable cans. Pref. a tear off closure is used, with the smaller opening preceding the larger in the direction of tearing, in the container cover; or there may be two spatially separate tear off closures. There may be a separate refrigerant container within the beverage container, with a separate filling and exit opening for the refrigerant. Cooling is effective only on use, and the liquid is cooled, not the container; no refrigerator is needed.

Title: Locking-device for washing-machine and spin-dryer lids - comprises magnetisable bolt operated by magnet in lid seating
Inventor: HUBER HEINRICH
IPC: D06F37/42
Filed: 1973-09-19
Abstract: A heating-coil, located in the electric circuit, heats a bimetallic element and holds the door-locking device in the locking position; the locking-device catches into the seating of the closed lid, as the bimetallic element obstructs the unlocking movement of the locking-element. A balance is operated by way of a handle for switching off the circuit and opening the lid, can be locked by way of a switch-bar that can be adjusted by the bimetallic element and the door-locking device, which can be retracted from th lid-seating by way of the balance and the handle by a mechanical connection. It consists of a locking-bar for the lid, made of magnetisable material and adjustable within the housing frame and is operated, in opposite direction, by a magnet, located in the lid-seating. Intrusion of water on to electrical locking-parts is prevented is what is a simply constructed washing-machine, esp. the type charge from the top.

Title: Pressurised sealed can - has membrane bearing for whole area against underside of lid
Inventor: WONS INGEBORG
IPC: B65D51/20
Filed: 1973-11-16
Abstract: The can is particularly suitable for accommodating freeze-dried foodstuffs and tennis balls etc., being subjected to internal pressure. The lid is secured in a flange ring, to which a thin sealing membrane is attached. The membrane bears against the lid over its whole area.

Title: Fluid bed coating - of powdered active components with lower melting agents to increase their free-flow and/or solubility or to combat hygroscopicity
Inventor: BRUENDL GERHARD DR
IPC: B01J2/00
Filed: 1974-09-02
Abstract: Powder particles may be coated individually by intensive mixing of a mixture of 92-99% active powdered component and 1-8% of pulverised coating material with a lower melting point than the active component, in a fluid mixer at a temperature above that of the coating material. The powder is then cooled to room temp. The process is used to obtain free-flowing powders for tabletting etc. even for hygroscopic materials, or to increase their solubility. The process is fast and economical and greatly increases the free-flowing and/or solubilising properties of the active components. The coating agents used are high-molecular polyglycolethers with reasonably low melting point such as esp. cetylstearylalcohol, castor oil etc. The powder mixture is heated in the fluid bed mixer whereby the coating material melts and coats the particles of active component. Hygroscopic material treated in this way no longer agglomerate. Coating agents contg. fatty acid salts such as sodium laurylsulphate-contg. cetylstearylalcohol increases the solubility of e.g. phenacetin in water.

Title: Actuating cam for switches and valves - is held in adjusting groove by wedging screw and expanding piece
Inventor: JENZ ERNST
IPC: B23Q3/10
Filed: 1974-12-18
Abstract: The actuating mechanism with cams operates switches and valves. The cam blocks are held in a fastening groove by clamping bolts. The cam blocks are held reliably without tilting and without undesirable displacement in the fastening grooves and the cam blocks are relatively cheap to produce.

Title: Data processing system with separate memory stages for peripherals - avoids need for peripheral instructions to be stored
Inventor: LOEFFLER KARL-HEINZ
IPC: G06F15/78
Filed: 1974-12-20
Abstract: A number of peripherals are readily coupled without undue demand on the main programme memory capability. The main processor system consists of a read-only-memory providing the main programme control of the central processor. A keyboard input communicates over control circuitry. A read-write memory provides storage for data from the keyboard and a general two way bus communicates information between units.

Title: Electronic cabinet bank centrally driven air cooling - provides one general air supply to entire cabinet and allows individual tray treatment (SW290376)
Inventor: CACCIA AURELIO
IPC: H05K7/20
Filed: 1975-08-21
Abstract: A centrally driven adaptable air cooling system is for electronic cabinets containing trays of printed circuit cards, with only one central air driving mechanism. An incoming air duct (4) is provided below a whole row or bank of cabinets between each of which is a vertical partitioned column up through which the air is directed. At each tray level within the cabinet is an adjustable vent (10) and the air travels through this, laterally across the cabinet cooling the circuitry as it does so, through a similar vent (10) and up through a similar column to the top of the cabinet. Here it is collected in a return duct (5) and returned to the drive. The adjustable vents allow different degrees of cooling at different levels in the cabinets.
