Title: Machine valve pipe fluid seal - is conical flexible element deformed around straight valve stem by clamp plate
Inventor: CONRADT RUDOLF
IPC: F16L5/06
Filed: 1973-06-22
Abstract: The flexible sealing element has a central hole to match the pipe. One end is cone shaped, the other end is cylindrical and is separated from the cone end by a rectangular groove. The mounting plate has a conical recess and the valve body has circular recess to match their respective ends of the sealing element.

Patent DE-2336530-A1 (DE)
Title: Spring-loaded rocker-operated combustion engine valve - rocker engages spring disc, releasing disc from valve stem before engaging stem
Inventor: ALTMANN WERNER
IPC: F01L1/12
Filed: 1973-07-18
Abstract: The valve spring disc is fitted to the valve stem by e.g. conical inserts or a spring ring, which will allow the valve disc to be pushed downwards relative to the stem, against the upward pressure of the spring. When released the spring disc will again engage the top of the stem and lift the valve to its closed position. The rocket has a spherical end engaging a spherical cup in the spring disc, and the spring disc is centrally open towards the top of the stem. The stem top lies below the cup surface by a small amount such that, when the rocker exerts a downward force, it first pushes the spring-disc downwards and, when the valve stem is thus relieved, it engages the stem top itself.
Patent DE-2340201-A1 (DE)
Title: Safety shutoff for condenser coolant failure - with source of gas/vapour shut off if coolant pressure falls
Inventor: ZOCHE MICHAEL
IPC: C01B31/08
Filed: 1973-08-08
Abstract: Should the coolant supply of town water or similar, to be shut off, a condenser in e.g. distillateous then the entering gases or vapours can escape into the atmosphere creating a fire or poison hazard, particularly for personnel in the vicinity. This is avoided by coupling a pressure sensor in the coolant supply line which shuts off source of gas or vapour in the event of a reduction in the coolant supply pressure by actuating a valve. This valve is fully open when coolant pressure is at the desired value, but closes or partially closes when this falls.

Patent DE-2352946-A1 (DE)
Title: End winding retaining cage for induction motor stator - is fitted with slots and locations for electrical connections
Inventor: MEHRMANN FRITZ
IPC: H02K3/50
Filed: 1973-10-23
Abstract: The end windings of the stator are contained and supported in an insulated cage or basket structure as in 2134523. This cage can be provided with slots in all or some of the axial supports of the cage. Stator coil to coil or similar connections, typically made by soldering, brazing or crimping, can then be pressed into these slots and safely retained therein without the need for further insulation. The retaining is made more effective if the slot opening is narrower than the slot width, so that the wire has to be forced into place and can only be removed with difficulty.
Patent DE-2354209-A1 (DE)
Title: Alternating voltage ozonizer - forms with high tension transformer resonant circuit with frequency adjustable to optimum
IPC: C01B13/11
Filed: 1973-10-30
Abstract: An alternating voltage ozonizer consisting of a discharge tube made of metallized ceramics receives its power from a high-tension transformer. The ozonizer forms a resonant oscillator circuit with the transformer. The ozonizer working frequency resembles the resonant frequency which can be adjusted by capacitances, inductions or magnetic transformer flux alterations. The ozone yield can be greatly improved by adjusting the optimum frequency. The operational attenuation is kept to a minimum and more energy is directed to the discharge. The ozonizers can have smaller overall dimensions.

Title: Serpentine-looped metal-tube assembly heat-exchangers - connected together with pressure generator and reducer in two sections
Inventor: STENZEL HANS-DIETER DR ING
IPC: F24D3/14
Filed: 1973-12-08
Abstract: The basic single heat-exchanger comprises a metal tube in serpentine loops held together by metal strips at a number of separate points. Two or more such heat-exchangers are joined together by connecting tubes, with a compressible medium contained in the closed system. In one of the two sections of the connection there is a pressure generator, and in the other section a device for pressure reduction.

Title: Reinforced concrete constructional elements - using mineral fibres in all or part of the cement or mortar, in addn. to steel
Inventor: MEYER ADOLF PROF DIPL ING DR
IPC: E04C5/07
Filed: 1974-02-27
Abstract: A space-forming shaped part, esp. building elements of reinforced concrete, the novelty being that the cement-bonded mortar and concrete is partially or completely, i.e. uniformly throughout the cement-bonded matrix, reinforced with synthetic mineral fibres such as glass-, stone-, slag-, or carbon-fibres, impact toughness, and for improving the distribution of fissures or cracks. The fibres may be incorporated in the element as lost shuttering a pre-fabricated part, a facing mortar, or inclused in the cement or concrete mixt, pref. using fibres with adequate resistance against the alkaline media where required and/or treating the cement mixt with CO2 to reduce the alkalinity. The improved mechanical properties, including elongation, means higher permissible stresses and/or redn in size and wt of constructional elements, fire-resistance is also increased. As compared with concrete or mortar in which no fibres are used, the bending strength can be increased 3-8 times and the elongation at fracture increased up to 20 times; bending strengths up to 600 kp/cm2 are attainable and the better distribution of fissures means less environmental corrosion.

Title: Piezoelectric ceramic resonator - produced by sintering extrusion in normal atmosphere creating lead depletion fringe zones
Inventor: FINK RUDOLF DIPL ING
IPC: H03H3/02
Filed: 1974-09-25
Abstract: Piezoelectric ceramic resonators are produced from continuous extrusions of ceramic matl., followed by a compact sintering oeration in a normal furnace atmosphere. This produces a lead depletion in the fringe zones adjacent to the surface. The extruded length is finally cut up into slices which are ground and polarised int he direction of the slice thickness. This is a simple process which is ideal for mass prodn. The transition between polarised zone and unpolarised fringe is continuous and smooth.
