Filed: 1977-06-28
Abstract: The parent patent describes an electric current generator. This improvement comprises using a star-shaped, rotating electromagnet assembly contg. two segments forming magnetohydrodynamic channels. Internal nozzles with ultrasonic vibrators are employed to accelerate a mixt. of metal vapours or steam with H2SO4, HCl, etc. into the channels. Ball valves control the movements of the vapours and gases in the channels and two boilers. The current generates is collected inductively or via internal electrodes. A diesel motor generator provides electric current for the magnets. The stream flowing through the channels consists of (a) high pressure K or Na held in pressure vessels with heating tubes, and accelerated via oxyhydrogen blowpipes; and (b) water contg. H2SO4 or HCl held in the boilers and fed through the channels back to the boilers.

Title: Postal sorting system operated by conveyors - uses photoelectric cell to detach post-bags from conveyor
Inventor: DENNERLEIN LOTHAR
IPC: B07C3/02
Filed: 1977-12-02
Abstract: A postal sorting system has a conveyor (1) which brings the letters to the sorting stations (2.1)(2.2)(2.3). The letters are sorted and placed in different postbags according to their destinations. Each post-bag is then attached to a conveyor (k) and as the bag passes a photo-electric cell (4.1)(4.2)(4.3) a signal is generated if the cell has been activated by the control panel (51)(52)(53). This signal is transmitted to the synchronising station (S) which controls the destination area (Z). The signal from the station (S) ensures that each post-bag is detached fromt he conveyor at the appropriate destination station (Z2800)(Z2900)(Z3000).

Title: Electrical resistance welding electrode - with heat resistant coating on working face for longer life
Inventor: BORGELT RALF
IPC: B23K35/02
Filed: 1978-02-04
Abstract: Electrodes for electrical resistance welding are made of copper or of a copper alloy with a high thermal and electrical conductivity. The entire working surface of the electrode is coated by a plated layer of a material with a higher heat resistance, pref. a copper alloy susceptible to pptn. hardening. Electrodes absorb the mechanical load by the hard and heat-resistant layer while the rest keep the temp. of the coating down. The result is a better cooling of the working area and a longer electrode life.

Title: Lavatory seat washing and drying unit - has cold water supply throttle to open main valve when heated water is released
Inventor: KURTH JUERGEN
IPC: E03D9/08
Filed: 1978-03-06
Abstract: The device for cleaning seats in water closet units has a programmed control mechanism, operated by knob pressure by hand or foot. Its motor tilts a jet assembly, normally resting above the basin and covered by the seat frame, to distribute heated rinsing water from an underspray. When operated, the programmed circuit opens a throttle (4) also attached to the cold water connection unit. When this conveys heated water, at reduced pressure, from a hot water storage unit (6) through the jet assembly, the main valve (12) is opened. The throttle may be preceded by a branching duct (9) connecting the cold water connection to the hydraulic motor.
Patent DE-2810360-A1 (DE)
Title: Heat storage pump operating by chemical decomposition - at low temps. suitable for solar collectors in temperate zones
Inventor: BRODALLA DIETER
IPC: F28D20/00
Filed: 1978-03-10
Abstract: Absorbed heat is used to decompose gaseous and solid components, the solid phase being in equilibrium with the pure gas phase at a given temp. and the resultant dissociation vapour pressure. The gaseous phase is pumped away, condensed, stored and then used when required to react with the solid phase and produce heat. Pref. the gaseous phase is reacted directly with the decompsn. prod. of th chemical cpd. in a second vessel at increased pressure. The reaction cycle is completed by alternating the uses of the two vessels. Specifically, the chemical cpd. is decomposed into a liquid and a gaseous component. The system does not require a high temp. for utilisation and is therefore esp. suitable for temperate zones.

Title: Submarine target simulator indicator - has two monitors with different scales and scene fading system in observation lens
Inventor: OELFKE MANFRED ING GRAD
IPC: G06F3/02
Filed: 1978-12-11
Abstract: The indicator is for a simulator depicting a scene with targets and surroundings as appearing in a submarine periscope on a monitor with grid. A computer forms a picture from components fed in at different scales on which the details are dependent, and other data concerning targets, characteristics of individual ships and bearings is also fed in. The number of details shown is reduced with the scale. On a second monitor with a similar grid a section of the scene can be depicted in greater detail, this being faded into an observation lens for the first monitor at the scale of the scene. The first monitor (1) is directly in line with the observation tube (2), whilst the second monitor (10) is on the same optical axis of a diminishing unit (12) and has the light beam deflected by two 45 deg. angle mirrors.
Patent DE-2853225-A1 (DE)
Title: Compressed air-supp-ied respirator mask - has lung-operated air supply assembly combined with air aspiration through filter
Inventor: GDULLA MANFRED ING GRAD
IPC: A62B18/00
Filed: 1978-12-09
Abstract: The face mask respirator for use in contaminated areas is supplied with air from a compressed air source. The compressed air supply is combined with a space air intake assembly fitted in the aspiration hose. During normal operation the respirator is supplied with compressed air while the overpressure inside the mask is higher than the breathing-in suction. Due to this overpressure the diaphragm bulges outward against the force of a spring and keeps the plug of the overpressure unit (5) in open position and the valve remains closed. If the compressed air supply fails or the hose is disconnected from the compressed air supply source, the pressure inside the mask decreases and room air intake takes place through valve and filter.

Title: Automatic determination of phenolsulphonphthalein in urine - using standard in alkaline soln. for automatic colorimetric comparison
Inventor: KAWAIN SHOJI
IPC: G01N33/52
Filed: 1978-12-27
Abstract: The presence of phenolsulphonphthalein (PSP) in urine is automatically determined by the addn. of an equal quantity of an alkaline colour reagent soln. to develop the colour in a 100% soln. The same alkaline soln. is added to urine samples taken from a patient over a series of time intervals. The reagent should have pigments stable in alkaline soln. The absorption for various wavelengths is then measured. The concn. is then calculated by a microprocessor which calculates the amt. of PSP passed by the patient over the time intervals involved. For use in checking the kidney and blood circulation of a patient by intravenous injection of PSP. Allows the urine samples subsequently collected to be automatically analysed.

Title: Interferon prodn. - using stimulators to increase yields
Inventor: SWETLY PETER DR
IPC: C07K14/555
Filed: 1979-02-17
Abstract: Interferon prodn. is carried out by incubating suitable cells with an interferon inductor and isolating and opt. purifying the resulting interferon. The cells used are either permanently cultivatable cells of lymphoblastoid origin (e.g. Nawalwa cells) or human fibroblast cells with a diploid chromosome set and a limited life or with a heteroploid chromosome set and limited divisibility.
