Title: Air compressor driven by IC engine - has exhaust gas turbine pre-compressor actuated by pressure from oil separator
IPC: F02B37/00
Filed: 1976-03-05
Abstract: IC engine (2) drives a screw compressor (5) via a shaft (4) and a coupling (3). The compressor output leads via a non return valve (7) to an oil separator (8). The oil returns to the compressor after passing through a cooler (38). Compressed air leaves the separator via a filter (11) to a min. pressure outlet valve (12). IC engine exhaust gas energy is used to turn a turbine impeller (16). The exhaust pipes (15a, 15c) (15b, 15d) are connected to pulse convertors (53a) (53b) in such a manner that the cylinder exhaust valve opening times do not overlap. The turbine impeller turns a compressor impeller (20) to draw air from a filter (21) and compress it at pref. a ratio of 1:2 in respect of the exhaust gas volume. Compressed air leaves the turbo charger (17) via an intermediate cooler (23) and non return valve (46) to a suction valve (25) and the main compressor intake. An oil separator pressure dependent starter valve (26) is fitted in the turbo charger output circuit to use the turbo charger output when a min. pressure is present.

Title: Tritium radioactivity determn. - in solns. contg. other radioactive substances
Inventor: ALI SAMEH ABDEL-HADI DR
IPC: G01T7/02
Filed: 1976-03-26
Abstract: An aliquot of the soln. under test is mixed with a strongly alkaline soln. in a container (to prevent volatilisation of radioactive impurities such as 'iodine' or HI). A body of adsorbing moisture is placed in the container in such a manner that it does not contact the liq. phase. The container (pref. a bottle) is tightly closed, e.g. with a screw cap (having a moisture-adsorbing body inside the cap). The moisture is allowed to reach the equilibrium state between the liq. phase, the gas phase and the adsorbing body (3 h at room temp.; 1 h at 50 degrees C). The adsorbing body is tehn transferred (with the cap) to another bottle contg. pure water, and the cap is screwed on. The bottle is subjected to ultrasonic vibrations whereby the adsorbing body is disintegrated and falls into the water. The radioactivity of the water dispersion is measured by the conventional method. This method is much simpler than the known methods. It is fairly accurate (plus-or-minus 5%). The detection limit is 10-7 conc. per sample.

Title: Solar energy collector with air-jacketed double-glazed window - through which cold water circulates to intercept any re-radiated energy
Inventor: SINGER KURT
IPC: F24S10/50
Filed: 1976-04-15
Abstract: The solar energy collector heats water circulated from a storage tank and to avoid loss of energy by re-radiation a thin sheet of cold water is put in front of the absorber, on the side that faces the sun. This cold water circulates (being supplied pref. from the coldest part of the storage tank) between two transparent plates, against each of which a layer of still air is held trapped by a further transparent plate. The transparent plate beside the sheet of water may have a radiant-heat-reflective coating on the side facing the absorber. The storage tank is fitted with a heat pump to tide over sunless periods.

Title: Variable geometry combustion chamber - has rotatable, axially movable outer casing and rotary slide valve, to vary secondary air
Inventor: ROHRA ALOIS
IPC: F23R3/26
Filed: 1976-05-08
Abstract: The variable geometry combustion chamber comprises an outer casing (1) which can be both rotated and moved axially with respect to the inner assembly (2, 3). A rotary slide valve (6. 6) controls secondary air drawn from the primary supply from the compressor; preheated secondary air is controlled by rotation of the outer casing (1) to vary the flow area through corresponding radial holes (17, 18) in the two casings (1, 2). Axial movement of the outer casing varies the flow area (12) for total secondary air and controls openings (16) by-passing the combustion zone (14). This also affects the degree of exhaust gas entrainment, through radial holes (15) at the combustion chamber exit via an ejector type nozzle (10).

Filed: 1976-07-02
Abstract: A bloated cellular prod. is prepd. by (a) mixing naturally occuring clayey material particles and an aq. soln. contg. dissolved nonoxidising flux and a bloating agent contg. reactable C to disperse and absorb the soln. into the clayey particles, (b) heating at a temp. and for a time sufficient to drive liq. from the soln. and cause dissolved flux and bloating agent to migrate to the particle surfaces and deposit there as water is driven off, (c) continuing heating at a temp. at which flux and bloating agent become molten and flow into the particles and (d) continuing heating at over 2100 degrees F until O contained in the clayey material reacts with C to produce a gaseous C oxide and the clayey particles become viscous, the bloating agent being so evenly dispersed in the clayey material that the gases are trapped, forming a cellular structure. The prod. has a good cellular structure and is useful as lightweight, heat insulating and fire resistant building materials, etc. The clayey material is clay or shale, esp. bentonite, fluxing agent is from hydroxides and phosphates of Na, K and Li and the bloating agent is sugar. The total time of heating steps is 10-120 min.

Title: Display device for car driver - projects map on screen and scans route by oscillatory movement of constant amplitude
Inventor: DEILE MARIE-LOUISE
IPC: G01C21/22
Filed: 1976-09-15
Abstract: The device rapidly supplies detailed information on the car position and destination. It has a projector which projects on a screen a large area map and/or a small section of it. The screen is placed in the field of vision of the driver. It uses for projection a microphotograph or a transparency in a holder. Either the microphotograph scanning device, or the photograph itself can be moved in both coordinate directions or rotated.

Title: Aromatisation time prolongation for barbecue herbs - by grinding, mixing with natural meals and pressing to pellets
Inventor: EFFENBERGER WILHELM ING GRAD
IPC: A23L27/10
Filed: 1976-09-29
Abstract: The aromatising time of seasoning herbs for barbecues is prolonged by grinding them and mixing then with ground materials such as hickory wood meal, maize metal, beech charcoal. The mixt. is pressed to the shape of pellets or tablets which are thrown on to the open fire. The herbs alone burn so fast that the desired aroma is often not imparted to the roast meat. This method extends the action time and improves the taste.
