Title: Horticultural subsoil irrigation at plant root level - by supplying water through PVC hoses at predetermined pressure to selected locations and dispersing
Inventor: KABAI DESZOE
IPC: A01G25/06
Filed: 1976-09-22
Abstract: Horticultural subsoil is irrigated by supplying water at predetermined pressure to predetermined points of the subsoil and discharging the supplied water at the level of the plants roots continuously independently of the supply pressure and distributing the water in a capillary manner. Pref. water is supplied through PVC hoses in the subsoil. Pref. the optimal irrigation is read into a programme, whereby the moisture content of the soil is measured at selected location and the measured values are used for controlling the irrigation intensity. Supply water is treated with the required plant feeding solns., which are taken into account in the programmed supply of water. Irrigation is uniform and attendant with low water loss, whilst plant requires little servicing.

Title: Single rotor gas turbine - has rotor acting simultaneously as compressor and turbine
Inventor: MAYER KARL DIPL ING
IPC: F02C3/045
Filed: 1976-11-04
Abstract: The gas turbine has a single rotor whose shaft is fitted ex-centre to the housing centre point. The guide vanes (6) are fixed to the housing. A baffle (7) separates the hot gases from the housing outer wall and at the same time forms a cooling air channel. The rotor is set in motion by a starter motor and iar is drawn in from the rotor centre and thrown forwards by blades on the suction side. The air is forced into a widened channel in front of the combustion chamber (9) to mix with the injected fuel and become ignited. The expanding gases act on the turbine side vanes via the guide vanes (6) to accelerate the rotor. The compressor could be fitted to one side of the rotor and the turbine on the reverse side for the full circumference.

Title: Extended action lift arm ram assembly - has interconnected cylinders adjacent to each other with pistons extending in opposite directions
Inventor: WEMHOENER HERBERT
IPC: B66B9/04
Filed: 1976-08-05
Abstract: The hydraulic or pneumatic assembly is for lifts and hoists etc. having two cylinders alongside each other and inter-connected. One piston extends to one side and the other towards the other, and the working faces of the pistons are of the same size, so that they extend simultaneously. Alternatively there can be three rams, one piston having a working face of area equal to the sum of those of the other two, which extend in the opposite direction from it, or four rams, two pistons extending to each side. Compared with existing designs the invention gives double the height of lift without increasing the space required by the ram.

Title: Extra light fuel oil preparation - by electric pre-heating before atomisation in burner nozzle
IPC: F23D11/44
Filed: 1977-04-19
Abstract: In a system for preparing extra light fuel oil for combustion through oil atomiser nozzles, the oil is preheated to a constant temp. before it is passed through the atomiser nozzle. The preheating can be effected by electric current or by the heat inherent in the mixing head, pref. to a temp. of 60-120 deg.C. The burner tube (1) inside the protective sleeve (2) houses a preheating chamber (3) with heating elements, supplied with current through leads (4). Oil is atomised by the nozzle (5) in the direction of the arrow (6). The oil mist is ignited by the sparking device (7). A mixer (8) ensures intimate mixing with the primary air (arrow 9). The oil passes from the pump delivery pipe (11) into a heat exchanger (10) and through pipe (12) into the preheating chamber (3). A thermostat (13) can be used for control, ie to activate the burner when the desired temp. is reached and to cut out the electric heating when the mixer head is hot enough to keep the oil in the exchanger at the desired temp.

Title: Pressure bearing taking up shaft axial forces - has springs between it and ring nuts forming intermediate pressure surface
Inventor: JASPER JOSEF
IPC: F16C27/08
Filed: 1977-04-28

Title: Heat treatment of helical coil springs - esp. valve springs for IC engines, to improve their properties at high temp.
Inventor: BACHE JOHN KENNETH
IPC: C21D9/02
Filed: 1977-11-26
Abstract: A load is applied to the spring, which is then heated until the spring relaxes and the load is reduced to a prescribed value of which the heating process is automatically interrupted; the residual load is then removed and the spring cooled, or a coolant is used on the spring while the residual load is still present.

Title: Rotation bearing for shaft journal under loading - esp. for drafting rollers on spinning frames
Inventor: TAKATA TOSHIYASU
IPC: F16C33/74
Filed: 1977-12-19
Abstract: A bearing permitting rotation under combined loads, comprises a cylindrical housing, and extending into this, part of a shaft, the end of which is supported in a bore in the bottom of the housing, so that external pressure can be applied. A ring fitting into a circular groove in the shaft, journal takes up internal pressure and rests against the face of a bearing between the shaft and the housing. A die cast or pressed ring formed by a number of parts is arranged between the shaft and the housing and a sealing element in sections together with a flanged retaining ring separate a lubricating chamber from a sealing chamber. The bearing is esp. applicable to the upper pressing rollers in spinning machine drafting units, but also in other textile machine technology. The brearing is of simple design and is simple to mfr. Oil leakage is prevented completely so that the chamber does not need to be filled so often, whilst the lifetime of the bearing is increased. At the same time, the penetration of dust and fly are prevented.

Title: Applying fertiliser to soil or plants - using water contg. inorganic components and organic phosphate colloids
Inventor: SEIFERT ERNST
IPC: C05G5/27
Filed: 1977-12-21
Abstract: Treatment of soil or plant cultures comprises applying water contg. a mixt. of fertiliser components, i.e. (A) inorganic components, (B) acid organic phosphate colloids and opt. (C) industrial effuents. The colloid provide a strongly acid pH, buffer the H+ concn. and bind the cations and anions of phosphate-contg. mineral fertilisers. Due to the low pH, neither N-reducing, gas formation nor CO2 loss from the sol occurs. Iron components can be partially reduced, leading to colour formation. The compsns. are esp. useful in the regeneration of subsided or marshy ground, they can be used with (semi)arid soils.

Title: Crushing reclaimed sand lumps in foundries - using air streams to remove dust before crushed sand is sieved
Inventor: SCHEEL HANS-JOACHIM
IPC: B02C17/14
Filed: 1978-02-27
Abstract: The sand is fed into a vibrating hopper fitted with double walls, and each sloping inner wall (a) is perforated so the sand travels through the holes as fine particles and through at least one cross-current of air functioning as a sieve, and removing dust from the sand. The air streams are pref. horizontal, and their force is adjusted to remove dust particles up to a predetermined size. In the pref. crusher, the dust-free sand then falls onto a sieve removing grains above a desired size, whereas the remainder of the sand falls through the sieve into a collection duct. Suction fans are pref. used to create the cross-currents or air.
