Patent DE-2966165-D1 (DE)
Title: Heat cycle system and method for producing fresh water from brine
Inventor: AMEND WILLIAM EDGAR
IPC: F01K25/04
Filed: 1979-11-27
Granted: 1983-10-20
Abstract: Steam, for example, is produced from aqueous brine, by a system that employs preferably hot waste fluid, and nozzle means and rotary separator means generally of a known kind per se. The method steps include transferring the waste heat of combustion source (22) to the brine flowing in heater exchanger coil (23), expanding the hot brine through nozzle means (24) to form a jet of steam and liquid droplets, causing said expanded flow to rotate the rotary separator means (26) for forming a liquid layer of said droplets on the separator means by centrifugal action while separating the steam (at 28), which is used to heat the incoming brine pumped by pump (11) in condensers (14, 13). The separated liquid from the rotating layer is used to drive turbine means (29) and the condensed steam provides fresh water from the brine. Several stages of separators may be employed in series or in series and parallel. Also, the steam may be used to assist in power generation. The system described is of low first cost and low operating cost, and is simple and reliable.

Title: Fuel-injection device for internal combustion engines, particularly for diesel engines
Inventor: LEBLANC JEAN
IPC: F02B3/06
Filed: 1980-12-24
Granted: 1984-09-13
Abstract: A fuel injection apparatus for internal combustion engines is proposed (FIG. 1), in which the onset and end of injection are determined by a hydraulically actuated control slide. The injection pumps of the apparatus, which are preferably combined with an injection nozzle to make a pump/nozzle unit, having a central magnetic valve assembly comprising two magnetic valves switched hydraulically in parallel, which valve assembly is inserted in a connection between a control pressure line, which can be placed under control pressure (PS) from a source of control fuel, and a low-pressure line which is under supply pressure (PV). In order to initiate the onset of injection, the control slide is placed under control pressure (PS) by the valve assembly via a distributor apparatus and closes an overflow channel leading out of the pump work chamber. In order to control the end of the injection, the control slide, during its return stroke, relieves this overflow channel toward a low-pressure line. The control pressure (PS) in the control pressure line required for actuation of the stroke movement of the control slide is built up by means of the valve assembly as a result of blocking the outflow from this line.

Title: Adjustable pitch propeller drive
Inventor: HIEBERT HAROLD LEE
IPC: B63H3/04
Filed: 1982-04-20
Granted: 1986-03-13
Abstract: A pair of axially movable abutments are spaced apart axially within a propeller hub. A plurality of adjustable propeller blades are rotatably mounted on the hub and each has an inner portion located inside the hub. Such inner portion is in the form of a pinion gear. Racks extend axially inwardly from each abutment and drivingly engage respective pinion gears on the blades. Compression spring or springs are positioned between the abutments and fluid pressure is used for applying an axially inward force on the abutments for moving both abutments axially inwardly toward each other in opposition to the force of the springs for the purpose of rotating the propeller blades in a first direction. The energy that is stored in the springs when compressed is used to rotate the propeller blades in the opposite direction when the fluid force is removed from the abutments. In two of the embodiments a driving shaft is solid, and the fluid motor for moving the abutments together is within the hub and in another embodiment the driving shaft is hollow and the fluid motor is positioned forwardly of the hub, connected to the forward end of the drive shaft. In the latter embodiment, the springs, in two sets, can be employed in the fluid motor.

Title: Filter for ostomy bags
Inventor: POULSEN FINN
IPC: A61F5/441
Filed: 1983-02-04
Granted: 1986-07-03
Abstract: In a deodorizing gas filter for ostomy bags (22), consisting of a sheet (10) of deodorizing filter material, for example a porous foamed plastic with particles of active carbon, and having a central inlet opening (12), a gas-tight connecting layer (14) to the bag on one side of the filter sheet, and a gas-tight covering layer (24) on the other side of the filter sheet, the covering layer consists of elastic film material, or is provided with a layer of elastic material at least in that part covering the central opening and an immediately surrounding zone thereof.This makes it possible to prick through the covering layer (24) and via the central opening also the bag in one with a needle, and still secure the desired passage of gas from the central opening (12) centrifugally through the fitter, since the elastic material of or on the covering layer results in the needle hole closing and remaining closed at the pressures practically occuring in ostomy bags, whereas the needle hole in the bag, having the form of one or more short tears, remains open because the bag film is of a thermoplastic inelastic material.Possibly, the filter (28) affixed to the bag (22) may be covered with a cover (34) to prevent carbon particles possibly falling out from the filter sheet (10) from dirtying the ostomy bag, said cover being tearable on account of a weakening line (38).
