Title: Crush-safe transportation of tubular aluminium container - involves placing resilient plastic tubes between ends of rows or containers and the box walls
Inventor: KOHL DIETER
IPC: B65D85/08
Filed: 1974-03-07
Abstract: Empty Al-tubes may be safely packed in containers esp. cartons, by stacking them, in known manner, in rows or layers staggered by half a dia. of a tube per row, and inserting at 1 or both ends of at least each 2nd row a resilient element (e.g. polyethylene) between container wall and row, the resilience of such element(s) being smaller than the denting resistanc of the Al-tubes. The resilient elements may be thin-walled plastics, esp. polyethylene, tubes. This reduces wastage of Al-tubes caused by crushing or denting in transit.

Title: Laminated rotor for small machines - is located by deformable clamp rings or bushes gripping the shaft
Inventor: KAMINSKI EGON
IPC: H02K1/28
Filed: 1974-03-30
Abstract: The application is to locate laminated cores on plain shafts which have no shoulder or similar stop. Each bush or ring has a flange which lies against the end of the laminations, and a bore slightly larger than the shaft diameter. With the punchings and bushes assembled on the shaft a die is closed, typically from each end, which pushes the parts to the correct position relative to the shaft ends. On final closing the dies deform the bushes so that they grip the shaft giving a secure location for the core. The laminations may be fitted around a pressure tube coaxial with the shaft and may be mounted in a conical section cup fitting into a face of the die which is opposite to the laminated core.

Title: Lightweight concrete plates prodn - produced by machining processes from blocks moulded in thermally insulating moulds
Inventor: RATH KARL FRIEDRICH
IPC: B28B1/50
Filed: 1974-04-02
Abstract: Lightweight plates of e. g. 'Styropor' concrete, having, if desired, channels running parallel to their width sides are mfd by (i) filling large volume and, more esp., thermally insulated block moulds with a mixt. xontg. e. g. foam material, cement, stone flour, lime, plastic binders etc.; (ii) pressing the mixture if desired, and storing it in the block moulds till it has hardened; and (iii) removing the block mouldings from the mould and sub-dividing them by machining, sawing etc. to give the parts to be produced. The block moulds are pref. closed on all sides after introduction of the mixture. Lightweight mouldings may be produced more cheaply and quickly, esp. thin plates with internal channels which slope with respect to the ends of the plate without producing the large amts. of waste inherent in known processes. Heat evolved, e. g. from the setting of cement, is conserved and utilised to accelerate hardening.
Patent DE-2416873-A1 (DE)
Title: Brake pressure modulator with non blocking valve - has pressure pegs in axial bores to hold sealing gasket away for valve ducts
Inventor: PRIEBISCH RUEDIGER
IPC: B60T11/34
Filed: 1974-04-06
Abstract: The brake pressure modulator has a special valve which is designed to provide a freely operating system. The sealing gasket for the valve piston is located in a wide groove, with the valve having axial bores leading to the groove from one side, and inclined bores leading to the other side of the piston. Special shafts are located in the axial bores with their ends resting against the sealing gasket at one end and on the modulator wall at the other end when the piston is pressed fully back. In this piston the sealing gasket could block the valve bores and jam the modulator. This is prevented by the shafts, which are joined together by a plastic ring to which the shafts are moulded.
Patent DE-2427991-A1 (DE)
Title: Direct conversion of thermal to electric energy - uses semiconductor layer to separate two substances at different temp and to form heat gradient
IPC: H01L35/00
Filed: 1974-06-10
Abstract: The direct conversion of the thermal to electric energy uses two electrically conductible substances separated by a thin semiconductor layer. The two substances are brought to a different temperature. The junction between the first substance and the semiconductor layer in the direction of the second substance is so formed as to permit low heat transfer by conduction and radiation to the second, cold substance. Alternately the heat may be rapidly dissipated from the second substance. Several such transformation elements may be series connected for summing up of the voltages of the individual elements. A parallel connection may result in increased capacity.

Abstract: The Parent Patent describes a horizontal tubular centrifuge for the continuous coating of wood fibres with adhesive in which the fibres are fed in at one end of a horizontal stationary tube and are rotated rapidly and propelled along the tube by a number of arms projecting from a longitudinal, hollow shaft revolving rapidly inside the tube, the shaft also has projecting from it radial pipes through which adhesive is centrifuge intimately into the mixture of fibres, the final product of coated fibres being discharged from the opposite end of the tube into a discharge hopper, the whole apparatus is incorporated into a pneumatic conveying line for the fibres, thereby achieving a uniform coating operation. In the Patent of Addition, each radial tube for centrifuging adhesive into the body of the wood fibres has its outlet openings in delivery tubes mounted transversely to the radial tube. In a variant (not shown), a single tube with a central opening connecting with the duct is used for both the tubes. The tube may be closed at the ends. The outlet openings are pref. disposed in the outward and rear quardrants of the tubes, as considered in the rotational direction. The delivery tubes may be continuous virtually along the entire length in which adhesive is to be distributed into the fibres. The radial tubes may reach with their tip almost to the inner wall of the vessel in which the shaft revolves. Uniform, non-clumping coating of the fibres with adhesive is obtained.

Title: Destination selector for transport units - adjustable ferrite core on unit excites stationary oscillator circuit to activate switch
Inventor: BOETTNER GUENTER ING GRAD
IPC: B61B10/04

Title: Housing for measurement and control instruments - applicable to pipelines having inlet and outlet pipes, esp. for water supply
Inventor: SCHMIDT KARL
IPC: G01F15/18
Filed: 1975-04-18
Abstract: The housing for measurement and control instrument consists of a C-shaped bracket to be fatened on a wall.

Abstract: A central heating system uses a heat pump and a refrigeration circuit with a compressor, evaporator and condenser for circulating a refrigerating medium combined with an accumulating and generating system which uses a combination of air temperature, water flow, the temperature of the ground underneath and around the site, the water contained within this region, and water pumped up from a much greater depth, and their temperature. These can be used in a closed or part closed hydraulic circuit which can be connected to the heat pump by an exchanger located at the outlet of the evaporator. The temperature and flow of water to this exchanger can be controlled in accordance with its temperature. The speed of rotation of the compressor can be controlled in accordance with the state of the refrigerating fluid at the outlet of the condenser.
