Title: Steel units for composite floors - has downwardly opening channel with longitudinal series of perforations
Inventor: SOWA WALTER DR ING
IPC: E04B5/40
Filed: 1974-07-03
Abstract: The steel plate forms part of the composite floor in conjunction with concrete in which it is embedded. The plates contain shear surfaces which transfer loads in the area of the edges of their upper rib. These surfaces are produced by cutting or perforation, or by cutting or perforation accompanied by local plastic deformation. The shear surfaces are located in a transverse direction in relation to the direction of the applied forces, and the perforations extend between rib and webs.

Title: Tubular reaction chamber and heating bath - for ninhydrin detection of amino groups e.g. in amino acids, from chromatographic analysers
Inventor: FELLENZER HELMUT DR DIPL PHYS
IPC: G01N33/487
Filed: 1974-07-04
Abstract: In a reaction system for carrying out the ninhydrin reaction at raised reaction temp. in the continuous liquid chromatography of substances contng. amino groups, partic. aminoacids, having a reaction chamber, in the form of a long thin plastic, partic. PTFE, tube (reaction coil) immersed in a heating bath, for the reception of the mixture of the eluate from the chromatographic column and the nin-hydrin solution, the heating bath consists of a liquid in which oxygen solubility, i.e. partial pressure, at the reaction temp. is low, more especially glycerol. The use of PTFE coils which are relatively cheap, thermally stable and easily handled, eliminates or considerably reduces the risk of blockage of the coils e.g. from corrosion products or precipitates as compared to the experience with steel coils which must be flushed out wherever the operation of the appts. is interrupted.

Title: Air-cooled engine valve play control system - has split rocker arm housing head bolted on cylinder head
Inventor: VYKOUKAL RUDOLF DIPL ING
IPC: F02F7/00
Filed: 1974-08-08
Abstract: The valve actuation system of an air cooled engine compensates thermal expansion in order to maintain valve play at minimum value. The rocker arms (4) of the valves (11) are arranged within a split rocker arm box with top (20) and base (17). The rocker arm is held on a ball (6) by a nut (5) on a rod (7) which is held in the plate (10) in the cylinder head (2). The stem of this rod is guided by the upper part of the cylinder head. Expansions are reduced by the air flow in the cylinder head and a hollow push rod transfers oil to the cylinder head for cooling. Reduction of valve play reduces noice considerably in air cooled high speed diesel engines.

Title: Safety fixing of ski-boot to ski - limits load exerted on boot but prevents complete separation of ski
Inventor: LUTZ DIETRICH DIPL ING
IPC: A63C9/00
Filed: 1974-11-21
Abstract: The ski-boot (1) is held by the retaining devices (2) to the ski (3).

Title: Plasma burner with adjustable coaxial arcing electrodes - with circular gap width set rapidly after arc formation
Inventor: DOMRES HANS GEORG ING GRAD
IPC: H05H1/34
Filed: 1975-01-23
Abstract: The plasma burner is for generating an open or closed arc, has an outer water-cooled cylindrical electrode surrounding a water-cooled axially-sliding central electrode. A differential cylinder (26) is located on the head (2) that carries the cylindrical electrode (1) and separated from the head by an insulator (29). The cylinder piston (25) is connected rigidly to the support (18) of the central electrode (11). The head with tube (3-5), the end plate (7) and the cylindrical electrode guide nozzle (8) form one weld unit. The advantage lies in being able to set the width of the circular gap between electrodes in as short a time as possible after the arc has been generated by bringing the two electrodes together.

Title: Local fuel burn up obtained by comparison of readings - from in core detectors containing different fissile materials
Inventor: FLECK CARL M DR
IPC: G21C17/06
Filed: 1975-04-28
Abstract: Local fuel burn up in a reactor is measured by obtaining at least two readings, using detectors, the values of which are determined by the changing concn. of specific nuclides in the fuel during burn up; the burn up is determined by comparing these readings. Pref. the readings are obtd. from fission chambers contg. different fissile materials, which are mounted in the core and/or introduced into it, esp. simultaneously. Two fission chambers may be combined into a unit either as compensating chambers or to obtain the ratio between the readings. Improved accuracy is achieved esp. by simultaneous readings, with no control rod movements taking place between them. One detector may contain U-235 and the other Pu-241, both shielded by a material which is selective to thermal neutrons. The ratio of the readings after processing, gives a measure of the burn up.

Title: Variable safety belt mounting - with self locking pivoted plate on door frame to accommodate different heights
Inventor: RENK ROLF ING GRAD
IPC: B60R22/20
Filed: 1975-09-04
Abstract: The shoulder belt of the safety belt system is fitted to a door pillar by a central bolt.

Title: Water pasteurising plant - with high-temp. storage boiler joined by heat exchanger to storage tank
Inventor: SEIFFERT MANFRED DR
IPC: C02F9/00
Filed: 1975-09-18
Abstract: A water treatment installation for the prodn. of pasteurised water consists of a storage boiler in which tap water is heated to a high temp. by heating elements. Water which is not required at a high temp. is passed into a storage tank. Pref. the tap water is passed through a storage boiler with heating elements, after it has been preheated in a heat exchanger. The hot water is taken through the heat exchanger to a storage tank. A negative pressure in the latter, when pasteurised cool water is taken from it, is prevented by a non-return valve, fitted with an air filter. The high temp. kills bacteria and converts halogens into soluble harmless cpds. or free gas. The installation is simple to operate and prevents reinfection from the atmosphere.

Title: Centrifugally casting metal dental restorations - using preheated lost wax mould hardened at high temp
Inventor: TAKAHASHI SHIGEO
IPC: A61C13/00
Filed: 1975-11-17
Abstract: In the prodn. of dental restorations by centrifugally casting a Cr-Co and/or Ni alloy into a mould formed by mounting a wax pattern on a support pin in a metal ring lined with a cushioning or elastic material, casting moulding material around the pattern, drying the mould, melting out the wax and hardening the mould, the improvement is that the mould is hardened at 700-950 degrees C for 20-150 mins. and the mould temp. is 100-500 degrees C before centrifugal casting. Hardening of the mould in the above temp. range ensures that combustible and volatile cpds. in the cushioning material and moulding material are driven off. Use of a hot mould reduces the formation of cracks by thermal shock. The castings produced have accurate dimensions and good surface finish.
