Title: Dispensing device for fruit juice mixed from fruit juice concentrate which is not ready to drink and fresh water
IPC: B67D1/00
Filed: 1982-03-10
Abstract: The dispensing device (1) for fruit juice consists essentially of a parallelepipedal housing with, arranged in the upper region, a cool box and, arranged in the lower region, a support plate (3) for a drinking vessel (4). Provided in the cool box (2) is a plastic bag (7), packed in a cardboard envelope (6), with fruit juice concentrate. The plastic bag (7) is provided with a dispensing tube (8) which is guided through a constricted-tube pump (9). A fresh-water pipe (19) of the dispensing device (1), which pipe can be connected to the water supply network, is with its outlet opening, like the free end of the dispensing tube (8), surrounded by a funnel-like transparent screen (11). In the fresh-water pipe (10), which is assigned a cooling aggregate, there is a shut-off valve which can be actuated together with the motor of the constricted-tube pump (9). On actuation of the shut-off valve and of the motor of the constricted-tube pump (9), a quantity, fixed in each case, of fruit juice concentrate and fresh water is filled into the drinking vessel (4) and there mixed by the turbulence  which is created at the same time. <IMAGE>

Title: Rotating mechanical seal
Inventor: WILKINSON SAMUEL CLIFFORD WALT
IPC: B63H23/32
Filed: 1982-05-03
Abstract: A seal arrangement, in particular for use in the stern bearing (4) of a ship, comprises an inner and an outer face seal element (6, 7) which are mounted on a rubber body (8) for rotation together with the propeller shaft (1). Any oil from the bearing (4) which gets behind the inner element (6), or seawater which gets behind the outer element (7), enters a cavity formed by pockets (9) in the body (8). These pockets are separated from one another by inclined blades (10) which act as a centrifugal pump in order to pass the leakage material through a passage (11) in a seat (5). The arrangement can also be used in other applications where the leakage material is corrosive or has a tendency to cause blockages. <IMAGE>

Patent DE-3229212-A1 (DE)
Title: Air outlet device for ventilating and air-conditioning plants
Inventor: BOITING H PROF DR ING
IPC: F24F13/072
Filed: 1982-08-05
Abstract: For ventilating plants, the conservation of operating energy is principally dependent on conserving fan power. Conservation of fan power is, however, only possible when the values for the conditioning of the supplied air are raised due to smaller volume flows. With the conventional tangential room-air guidance systems, a reduction of the power requirement cannot be achieved with simultaneously sufficient conditioning of the supplied air and taking comfort into account. For decisive improvement, an air outlet device is proposed which uses controllable slot outlets with eccentrically mounted rotatable rollers as airstream control elements, and in which the slot outlet elements are distributed, with their outlet openings, in a star shape around a common central axis to form a circular blowing outlet vortex chamber, and are arranged in the envelope plane of the blowing outlet action.

Title: Butt connection between two sheet-metal tubular sections
Inventor: MEINIG MANFRED
IPC: F16L23/032
Filed: 1983-04-19
Abstract: A butt connection between two thin-walled round sheet-metal tubular sections has in each case one flange ring which is placed on the tube ends and has an approximately triangular profile. In order that the ends of the flange rings, which are bent out of a sheet-metal part forming an axial slot in their annular shape, cannot be displaced with respect to one another once the tube ends have been knocked on, said ends must be fixed in their respective position. This is achieved according to the invention by a bridging part which engages in a flush manner in each case in the triangular profile of the mutually opposite flange ring ends. An embodiment is described which can be produced particularly easily, operates reliably and can be actuated conveniently, as well as a device for sealing the axial slot which is produced.

Title: Solar grill
Inventor: ARRAS GEORG
IPC: F24S20/20
Filed: 1983-11-26
Abstract: A basic idea of my invention is the focusing of sunlight by means of Fresnel lenses, and the possibilities produced thereby for storing energy. The sun makes three movements over the year. The focal point absorber tube is identical in mirror fashion in two movements of the sun and tracking of the useful diurnal path reduced by the optical focusing of the cylindrical Fresnel lens. It is possible given the high temperatures of the heat carrier to carry out chemical analyses, to distil, e.g. using steam (endothermally) or to carry out electrolyses via direct or indirect production of current, e.g. to split water into hydrogen and oxygen. These substances can be stored without loss of energy. Since roads carrying traffic (motorways) require a height of only up to 6 metres, and house roofs in summer only heat up uselessly, they are the ideal location for my system. It is possible using a sailing vessel which carries the system as a sail also to use the lens as a wind sail by employing an additional horizontal rotary mechanism. Cylindrical Fresnel lenses can be produced by extrusion, injection moulding or casting, and by cutting individual prisms to size from transparent plastics.
