Title: Composite construction interrupted reinforced concrete slab - has parts linked by girders with cutouts or latticed
Inventor: LAUMER RICHARD DIPL ING
IPC: E01D2/02
Filed: 1975-05-06
Abstract: The reinforced-concrete element, for use in composite construction, consists of a slab which is interrupted at one or more points. The interrupted parts of the slab (1) are joined together by one or more girders (3) which project upwards. The girders are pref. provided with cutouts (4) above the slab or the girders may be in the form of a steel lattice structure. The slab may be bent upwards at the edges (2).

Title: Damper bearing for turbine shaft at super critical speed - has helical throttle groove for bearing oil regulated at reduced flow
Inventor: HAGEMEISTER KLAUS DIPL ING
IPC: F01D25/16
Filed: 1975-09-27
Abstract: The inner solid shaft of a twin shaft gas turbine rotates in the supercritical speed range which requires a damper bearing. The bearing oil arrives at the damper section through a ring chamber formed by the outer hollow shaft and the inner shaft. After passing axially through the bearing, the oil reaches the collector chamber from where radial holes in the outer shaft drain it into the outer bearing housing. When only the inner shaft is rotating, a helical groove on its bearing dia. moves the oil through the damper bearing at a reduced flow rate. A seal ring between the collector chamber and the turbine wheels reduces the amount of gas that can reach the bearing oil.

Title: Radial piston type hydraulic pump - has non return valves immediately on outlet of cylinders at discharge commencement
Inventor: BUDECKER LUDWIG
IPC: F04B1/107
Filed: 1975-11-19
Abstract: The pump has a cylinder block (4) which is driven round a stationary valve hub (3). The cylinders in the block contain pistons which press against an outer stationary guide ring (8). This is eccentric to the axis and causes the pistons to reciprocate. The valve hub has an inlet passage (10) communicating with a radial opening (12) which the ends of the cylinders pass as the cylinder block revolves. A discharge passage communicating with several radial openings (24) leads to a discharge valve. The radial passages which the cylinders pass at the commencement of discharge have ball non-return valves which are held in a valve block (20) within the hub.

Title: Electric power generating plant driven by flowing water - consists of wheels with bucket belts mounted in floating structure
Inventor: WIEDUWILT GEORG
IPC: F03B17/06
Filed: 1976-03-06
Abstract: The structure of the power generating installation is supported on floats and is anchored in a flowing river. No structural parts are used to fix the structure to the banks of the river or to support it from the river bed. Energy is extracted from the flowing water by means of chains on which buckets are mounted with the opening facing upstream. The bucket chains run over two wheels. The power from the water is extracted at the wheel shafts and transmitted via a gear drive to a generator. To increase the amount of power generated, several chain wheels can be mounted next to each other or behind each other.

Title: Nitrogen-contg. fertiliser - contains gelatin waste and a soil improving agent which can absorb oil
Inventor: POTTIEZ PAUL
IPC: C05F11/00
Filed: 1977-02-03
Abstract: A fertiliser for higher plants which can be sprayed and which contains nitrogen contains (a) highly pure gelatin-waste from the food or pharmaceutical industry comminuted so that it can be sprayed and (b) at least one soil improving agent which can absorb oil. Component (b) is suitably bark or peat. Vol. ratio (a):(b) is 20:10-20:1, pref. 20:2. The fertiliser can be used for agricultural and garden plants.

Title: Inbuilt installation switch with pressure actuator - has adjustable control elements and fastening members
Inventor: TESCH BERNHARD
IPC: H01H13/14
Filed: 1977-04-20
Abstract: The switch is intended for fixed mounting in electric appliance, or their part. It is controlled by a pressure of a moving element against the switch actuator. The members for the switch actuation, or its securing, are produced with sufficient tolerances for mounting in different appliances, or are adjustable. The design of the members preferably affords a single adjustment only, which may be obtained by permanent deformation, such as bending. Frictional connection may be also used for this purpose. If the actuator is in the form of a pressure plunger, it may consist of two telescopic parts, coupled together by friction. If the actuation is effected by a lever, the latter is flexible in a limited section.
