Title: Noise reduction for flow systems with gaseous or fluid media - has elements constructed from sheet metal in jet engines
Inventor: HAYDEN RICHARD EARLE
IPC: G10K11/16
Filed: 1973-06-29
Abstract: The flow system includes e.g., propellor blades for turbines, jet engines etc., with high noise levels produced due to current flow over the surface of the element. This noise is reduced by a reduction of the fluidic friction between the fluid and the surface of the element, by providing the latter with an outer covering of porous matl., or shaping its leading and trailing edge. Pref. the porosity of the matl. varies along its length e.g., with a minimum value midway along the element.

Title: Heating element for hair dryers - spacings between the heating coil layers increase towards air outlet aperture
Inventor: ARBTER ERHARD
IPC: A45D20/38
Filed: 1973-10-04
Abstract: A heating element for hair driers especially of the hand-held type. The design aims to produce an even temperature of the heating wire over the complete winding. The danger of overheating and glowing of the forward turns of the winding is avoided. The spacings between the coil layers are varied so that the spacing increases in the direction towards the air outlet aperture in uniform or non-uniform steps. The distances between the windings on the ceramic, or other insulating material, core are, for instance, uneven or chosen from the formula a + (n-1)k, where a is the distance between two windings, n the number of windings counted from the air inlet and k a constant, for example 0.2 mm.

Title: I.C. engine electronic optimum ignition timing regulation - work content of individual cycles is electronically computed and difference is used as setting parameter
Inventor: KUNZ WUNNIBALD
IPC: G06F7/62
Filed: 1974-03-15
Abstract: Electronic regulation for the maximum output adjustment of the ignition point of combustion engines working on the Otto principle especially for reciprocating and rotary piston engines for motor vehicles where the work content of the individual cycles is computed via the pressure variation in the cylinder and this computation is electronic. The difference in these work contents is used as a setting parameter to vary the ignition point. To evaluate the contents the pressure variations are not measured over the full operating cycle but only during the compression and expansion strokes. To reduce the electronic components, the contents of one cylinder only are used.
Patent DE-2415629-A1 (DE)
Title: Temporary voltage dependent blocking cct. - triggers current branch on max. operating voltage, while reblocking on values below max.
Inventor: NUTZ KARL-DIETHER DIPL ING
IPC: H02H3/24
Filed: 1974-03-30
Abstract: The circuit is intended for temporary current blocking, dependent on the operating voltage value. The current is switched through on a maximum value being reached, and blocked again when this value drops below this maximum. Thus it protects the sensor circuit in a triac phase control circuit from high switch-on noise. A transistor switch is coupled to the sensor and to the input by its collector, and its base is connected to a second transistor switch and a constant current source. A second current source is coupled over a zener diode and a voltage divider to the second transistor base. The zener diode is shunted by two transistors together acting as a thyristor.

Title: Air tight valve for granulated material - has pneumatic cylinders for clamping valve slider blade against O-ring seal
Inventor: LORENZ KURT DR
IPC: B65D90/58
Filed: 1974-07-02
Abstract: An air tight shut off valve for granulated material has a slider bladed which is actuated by a double acting cylinder from outside the valve body. When the slide blade is in the closed position, it is located between a pressure ring and a seal ring which carries an O-ring. Single acting clamp cylinders act axially on the pressure ring so that the slider blade is pressed against the O-ring, thus producing an air-tight valve seat.
Patent DE-2437534-A1 (DE)
Title: Converter synchronous machine with AC excitation - has stator supplied from externally-commutated converter and rotor supplied from polyphase supply
Inventor: BOEHRINGER ANDREAS PROF DR ING
IPC: H02P25/024
Filed: 1974-08-03
Abstract: The machine has a.c. excitation, and the polyphase stator of an a.c. machine receives its electrical energy from an externally-commutated static converter. This a.c. machine has a rotor which is supplied from a polypphase supply such that the machine can deliver its full rated torque at any speed between zero and its maximum without requiring that the static converter coupled to the stator of the machine be subjected to forced commutation. The machine can therefore operate simply and reliably as a commutated converter and it is capable of functioning as either an inverter or rectifier.

Title: Press for applying pressure and heat to chipboard - has closely spaced short roller chain sections for load transmission
IPC: B30B15/34
Filed: 1975-01-09
Abstract: The press for exerting surface flattening pressure together with supply of heat on a longitudinal section of a moving strip is used especially for continuous production of chipboard. The material is fed on a wide belt in the press. The pressure and the heat are applied to the material by a system with rolling chain supports, and these chains are relatively short even if the pressing region is long, in order to ensure ready handling. The chains transmit the working pressure from the support structure to the conveyor belt. The chain arrangement is subdivided in the longitudinal direction into a number of closely succeeding independent endless chains (14, 14'). These chains roll around support plates (40, 40') on upper and lower sides of the moving material strip.
