Title: Eccentric helical plastics pump rotor - has metal core with torque transmitting coupling
Inventor: DAUNHEIMER ERICH
IPC: F04C2/107
Filed: 1975-07-04
Abstract: Rotor screw made from plastics and used in a helical screw pump, in which rotor strength is increased by using a metal core. Rotor of helical shape has metal core (1) which has at one end the coupling element (3) which projects beyond the plastics part of the rotor helix. The rotor core can be joined by pressing or sliding fit can be used between these two components, a clamping screw may be used which passes through the metal core. The driving torque is transmitted to the rotor by a metal coupling element on the core end. Since no torques are transmitted through plastics, the plastics rotor therefore has a significantly longer life. Splines or serrations are used to prevent any relative slip between the core and the rotor.
Patent DE-2534278-A1 (DE)
Title: Pulsed tungsten inert gas welding - with pulsed current decay to avoid end crater defects
Inventor: KRUEGER FRIEDRICH
IPC: B23K9/12
Filed: 1975-07-31
Abstract: A constant distance is maintained between the electrode and the workpiece and the current alternates between a higher pulse current and a lower base current. Relative movement takes place between the welding head and the workpiece, and the current is slowly reduced at the end of the joint. The relative speed of the welding head and the workpiece is reduced during the current decay; alternatively it may be zero. The process avoids the formation of an end crater and porosity by a simple technique.

Title: Double push pull modulator - avoids selected transistors by forward biasing emitter to base junctions in absence of carrier
Inventor: SONNTAG FRITZ DIPL ING
IPC: H03C1/54
Filed: 1975-07-31
Abstract: The double push-pull modulator is highly symmetric and requires no specially selected transistors for its push-pull pair. The input signal is coupled via a transformer to the bases of two complementary transistors forming a push-pull pair. The collector outputs are coupled to an output transformer. A biasing voltage source (UV) is coupled to the centre tapping on the second winding of the input transformer (4) such that when the carrier signal is absent the base/emiter junctions of the two transistors are forward biased. The bases of the transistors are coupled via resistors to the ends of the input transformer's secondary, and their common emitters are earthed via an RC circuit.

Title: Cct breaker - has contact for vacuum current less zones behind main current-carrying zones to speed arc extinction
Inventor: GOETSCH ALFRED
IPC: H01H33/664
Filed: 1975-10-16
Abstract: The contact is intended for a vacuum circuit breaker and has special almost currentless zones (2) behind the main current-carrying regions (12). The currentless zones have a resistivity that is higher than that of the surrounding contact material and have Slater coefficients below 3 or above 7.7 and/or insulating material and/or surrounded by a vacuum. These currentless zones extend at least as far as the edges of main current-carrying regions. The currentless zones ensure that the light arc produced between the main current regions migrates as quickly as possible under the arcing regions of the switch, where it then circulates and is extinguished.
Patent DE-2546785-A1 (DE)
Title: X:ray photograph to reform spatial image - utilises X:rays from several sources which pass through same raster to create 3-dimensional image
Inventor: KLOTZ ERHARD ING GRAD
IPC: G03B35/00
Filed: 1975-10-18
Abstract: The object (19) is irradiated from several X-ray sources at once (16), and the transmitted beams pass through a raster of holes or slots (20); the sources are so positioned with respect to the raster, that the several beams passing through the holes do not overlap at the photographic surface (21), though they preferably cover it completely. A second raster screen (22), chosen not to intercept any rays that contribute to the photographic image, may be placed in front of the object. A three-dimensional image of the object may be reconstructed from the shadow-graph and raster by illumination from behind, using a lens to focus light on the points (16) where the X-ray sources were. Thus the rays that formed the photographic image are re-constructed, at their shadow-graph intensities, and may be intercepted and displayed, section by section, on a screen held where the object was. Alternatively, a computer can be used to calculate sections from the known geometry.
Patent DE-2550137-A1 (DE)
Title: Wedge anchorage for cable load on concrete members - has inside serration pressing in at full height and high transverse pressure

Title: Roller shutter for window or door - avoids heat loss using wear resistant IR reflective surface coating
IPC: E06B9/58
Filed: 1975-11-15
Abstract: Heat preserving installation e.g. of a roller shutter, on a window or door, where the greatest heat loss from a building normally occurs, is made so as to have pronounced infra-red reflecting qualities, on the inside and/or outside, with max. wear resistance. This can be applied to traditional roller shutters, which can also be made draught-proof with the slats pressed close together, these may be in the form of hollow foamed profiled. A draught-proof layer (10), which is infra-red reflecting, and may be transparent, may be fitted on either side, and this can be stiffened with batten-type strips (11). Intervening spaces may be foam-filled. This prevents heat loss, esp. in winter when the long hours of darkness result in the closing of shutters for more than half the time.

Title: Mixer for resin and sand - where resin constituents are fed via separate pipes onto profiled mixing rotor
Inventor: HALLER WALTER
IPC: B22C5/02
Filed: 1976-04-07
Abstract: Resin and sand mixer has walls which form a sand inlet followed by an annular channel through which the sand flows into a mixing zone. The mixing zone includes a profiled stator located above a rotor leaving an irregular gap through which the mixt. is compelled to flow in an undulating manner towards the mixer outlet. The individual constituents of the resin are fed through separate pipes into the mixing zone so that at least one of the constituents falls onto the upper profiled surface of a dish fixed on the top of the rotor. A ring is pref. mounted above the dish so as least one of the resin constituents falls through the axial hole in the ring onto the dish. Used for foundry moulding sands. In conventional sand mixts., the two constituents of the binding resin are made into mists using air, and the air-mists are explosive. The invention does not use compressed air to assist mixing, avoiding the danger of explosions.
