Title: Spray system for cooling liq. bodies - by forcing air through liq. spray chimney
Inventor: ROSE CLARK B
IPC: B01F3/04
Filed: 1976-11-04
Abstract: A novel liq. spray system for cooling a body of liq. comprises a press. nozzle for producing from the surface of a liq. a liq. spray chimney of inverted frusto-conical shape. The liq. spray chimney encloses a mechanically generated air draft produced by a fan having an exhaust outlet positioned within the frusto-conical spray trajectory configuration. The system is used for cooling water in a river or tank heated by the hot discharge from nuclear or fossil-fuel powered electricity generators. Cooling is not dependent upon natural wind conditions to produce the air velocities necessary for efficient cooling. Liq. loss from the system is reduced because the droplets in the liq. spray chimney are sufficiently large not to be entrained and carried away in the air draught.

Title: Combined rotating and tilting window - has readily disconnected stay lock at moving frame top member
Inventor: MAYER SIEGFRIED DIPL ING
IPC: E05D15/526
Filed: 1976-12-23
Abstract: The combined rotating and tilting fitting is arranged on an optionally rotating or tilting window. The moving frame carrier actuating rods may be adjusted between closing, rotating and tilting position. The actuating linkage of the moving frames can be locked against adjustment. The locking element acts in conjunction with a locking element catch on the actuating rod (26). This locking element is disconnected by the adjustment of the actuating rod from the locking catch, and an actuating element is moved in relation to the tilting movement of the moving frame (12). This actuating element facilitates the displacement movement of the locking element when the window moving frame is closed and it also prevents the displacement of the locking element when the window is fully or partly open.

Title: Transportable jack-up offshore well drilling rig - is moved to or from site on bow or stern of floating vessel
Inventor: DYSARZ EDWARD DAVID
IPC: E02B17/02
Filed: 1977-06-02
Abstract: A transportable jack-up offshore well drilling rig has a relatively light openwork superstructure and three legs, and is transported to or from site in an upright position on a vessel which supports the rig at one end such that two of the legs extend down opposite sides of the vessel, while the third leg extends down in front of or behind the vessel. If the legs extend into the water during transport then the rig is typically arranged at the stern of the vessel but if the legs are clear of the water during the transport then the rig may be arranged at the bow of the vessel. The rig may be designed for tender assistance, in which case it carries only the drill works (derrick, draw works and rotary table) and a crane and all the other equipment (mud pumps, spare drill pipe, crew's quarters etc.) is carried on a floating tender moored to the rig, or it may be self-contained and require no permanent tender assistance. In either case, it may be converted to a well prod. platform after the drilling is completed. It is cheaper to construct than conventional rigs, towed to or from site, and is less likely to be damaged during installation or recovery.

Title: Hydrostatic sea water heat storage - has buoyancy force compensating sand ballast with warm water storage hoses
Inventor: VINZ SIEGFRIED DIPL KFM ING GR
IPC: F28D20/00
Filed: 1977-10-26
Abstract: The hydrostatic system is used for heat storage from sea water. Warm sea water in the summer is stored for heating purposes in the winter. Buoyancy forces generated by warm water in cold water are compensated. Buoyancy forces are compensated by sand ballast within the plastics hoses storing warm water. Weight of hoses is increased by cold water replacing the warm water drawn for use. This cold water also generates additional delivery pressure. Buoyancy forces can be also compensated by upright vertical plastics hoses. These hoses can project above water by the extent of weight required for compensating buoyancy forces.

Title: Ink jet printing machine head - has air exclusion system with valves preventing peak pressure transmission to ink reservoir
Inventor: FISCHBECK KARL-HEINZ
IPC: B41J2/19
Filed: 1978-06-12
Abstract: The system avoids air being drawn in during the suction phase of an ink-jet-type printing head. Ink is delivered via a chamber in which peak pressures are briefly generated, the passages to and from the chamber being alternately opened and shut. The feed and discharge passages (20, 21) each have a valve reacting to the peak pressures and preventing their transmission to the ink reservoir. Each valve has a seat formed by ribs (14, 17) and their edges, against which a diaphragm bears in the unpressurised state, together with an antechamber (10) holding the portion of the diaphragm thrust clear when the valve opens.
