Title: Cleaning membrane exchange device - using a plug flow of air-entrained droplets
Inventor: JENNINGS JAMES LAWRENCE
IPC: B01D65/06
Filed: 1975-09-27
Abstract: A rapid method of cleaning the membrane surfaces of membrane separation units comprises partially filling the passageways of the units with water, periodically purging the passageways with a continuous air stream at super-atmospheric pressure to cause a non-plug flow of water droplets at high speed to remove deposits, this operation being performed after conducting an osmotic back flushing, the purging step being repeated to effect removal of all deposits and all water droplets without permitting drying of the membrane at any stage. The method is much faster than plug flow liquid cleaning solns., and uses minimal amounts of cleaning liquid.

Title: High compression vehicle IC engine - has inlet valve arranged to shut late and small vol. combustion space
Inventor: PIECH FERDINAND
IPC: F02D13/02
Filed: 1975-10-07
Abstract: The otto cycle four stroke engine operating process is particularly for motor vehicles. The inlet valve shuts so late after bottom dead centre that the smaller effective compression stroke gives the desired compression ratio in conjunction with a smaller clearance volume. In the speed range corresponding to maximum torque a quantity of mixture roughly equal to the capacity of the clearance volume can be pumped back through the inlet valve into the inlet manifold. The inlet valve can be arranged to shut at up to 90 degrees after bottom dead centre. Fuel can be injected continuously via a nozzle in the inlet manifold, aimed at the inlet valve.

Patent DE-2555055-A1 (DE)
Title: Position sensor with two outputs - has separate amplifiers in each channel with set response threshold
Inventor: MUELLER ROLF DIPL ING DR ING
IPC: H02K29/08
Filed: 1975-12-06
Abstract: The sensor (11) is typically a Hall generator and may be of integrated circuit type incorporating output amplifiers. Instead of the conventional differential amplifier for processing the output separate amplifiers, typically transistors, are used (17, 22), each receiving the full voltage from the sensor but in the opposite sense. As the transistors have a threshold voltage before they begin to conduct small sensor errors due to stray fields have no effect on the circuit. Use of amplifiers coupled in this way eliminates the output which is always present in a differential amplifier, and ensures that the circuit only responds to a legitimate, large, signal. Applications are brushless DC motors and other position sensing duties.

Title: Diagnostic X:ray appts. with variable tube heating voltage - has voltage set by shunting out resistors in series chain using relay contacts
Inventor: KLAUMUENZER HARTWIG ING GRAD
IPC: H05G1/34
Filed: 1976-01-08
Abstract: The diagnostic X-ray appts. uses several fixed resistors to set the X-ray tube heating voltage. Starting from the first resistor, each subsequent resistor has twice the value of its predecessor. Each resistor can be shunted out of the series chain by relay contacts in parallel with it. The relays are controlled by binary counters. The count is converted into analog form and compared with a given voltage. The count is then adjusted so that these two voltages are the same. The given voltage is set by to the required value by means of a potentiometer or stepping switch.

Title: Heat store for solar energy - using radiation trap panel which passes radiation in solar wavelength but reflects other
Inventor: PUSCH GUENTER DR ING
IPC: F24J2/40
Filed: 1976-06-29
Abstract: Solar energy is stored by using a radiation trap panel. This transmits solar radiation in the wavelength range 0.3-2 mu m but largely reflects radiation in the range 3-20 mu m. This filter panel is made from a transparent material on which a metal layer is vaporised on the side facing the sum of several nm thick. A dielectric coating can be applied which has an optimum transparency for solar energy. The dielectric layer serves to protect the applied metal coating. The carrier material is a thin, transparent plastic foil. Several such radiation traps can be separated by a diathermal gas layer. Several layers of metal can be applied, sepd. by thin insulating layers. Prevents the reradiation of energy picked up by the store.

Title: Granular building materials of coated plastics particles - for incorporation into concrete, bitumen, etc.
Inventor: HABERL PAUL
IPC: C08J11/06
Filed: 1976-08-11
Abstract: Granular building materials consisting of polymeric (pref. thermoplastic) particles (A) whose surface is extensively covered with another material, (B) such as finely divided sawdust, sand, a silicate, metal powder, or a (semi) continuous rubber film. Used for the dispersion of additives in concrete (e.g. setting accelerator or retarders, fillers, etc) or in bitumen (e.g. materials to improve bond to mineral fillers, flow behaviour or foaming). Accurate weighing and homogeneous dispersion of the additive are simplified, and a standard freer flowing granular material is obtained, regardless of the form of (B) or the temp. Mixing conditions (temp., moisture, etc) are not critical and prolonged hot mixing of bitumen is not required for homogeneous dispersion. Typically scrap PE film is cut into chips, with heating to around 90 degrees C and latex is sprayed in whole mixing. Those cools the chips and covers their surface, with evaporation of part of the water. The product can be stored in sacks.

Title: Light liquids separator esp. for oil sepn. - has baffle plate upstream of outlet to improve arrest effect
Inventor: NOEH HORST
IPC: B01D17/02
Filed: 1976-08-31
Abstract: A separator for light liquids comprises a tank with an inlet near the top and an oulet at the opposite end or side and near the bottom for the heavier liq. In the general, central region of the tank. a baffle plate, with a surrounding gap between it and the vessel wall, is mounted on the upstream side of the outlet. Pref. this baffle plate does not project above the liq. surface. Pref. also it is concave on its upstream face. Used as a separator for removing light liqs. from effluent, surface water or the like, in particular as an oil separator. The use of a baffle plate enables the speed of flow through the tank to be increased for a given efficiency of sepn. or in other words the total through put for a given size of tank to be increased. Very small oil droplets which would otherwise enter the outlet are trapped by the plate. They thus combine with other droplets and ascend to the surface to be sepd. with the light fraction.

Inventor: FONTANA ALBERTO EMILIO DR
IPC: A61M21/00
Filed: 1976-11-05
Abstract: Research has proved that music induces repose and sleep better if it is accompanied by quiet (artificial) heartbeat sounds at 60-90 (pref. 84) per minute and even quieter (artificial) breathing sounds at 10-20 per minute. Sequences of music and natural sounds last about half an hour. The sounds are chosen for their emotional effect, and pass from cheerful to re-assuring to natural to unworldly. The heartbeats start at 20 dB below th music intensity, and rise to 10 dB below it. the breathing sounds rise from imperceptible to 15 dB below. At the end, the sound is slowly faded out.

Title: Operating mechanism for doors of model railway carriages - uses diodes connected in parallel with solenoids to open or close doors
Inventor: SCHMERENBECK PETER
IPC: A63H19/16
Filed: 1976-11-30
Abstract: The doors (1) of the carriage of a model railway are mounted on hinges attached to the door frame (2). A double solenoid (3) (4) with a common armature (5) is mounted above the door. The mid-point of the armature (15) is connected by pivoted rods (6) (7) to the edges of the doors (1). the solenoids (3) (4) are connected in series and a diode is connected in parallel with each solenoid. When a voltage is applied to the circuit the current is blocked by one diode so that the current flows through its associated solenoid. The other diode permits the flow of current so that its associated solenoid is by-passed. When the current flow is reversed the actions of the solenoids are reversed. Thus one solenoid (3) opens the doors and the other solenoid (4) closes the doors.
