Title: Electrostatic solids separator - using fluidised bed with top extraction of charged particles
Inventor: BRANDHOFF WILLI
IPC: B03C9/00
Filed: 1971-07-01
Abstract: Appts. for sepg. of solids comprises a porous floor through which gases flowing upwards form a fluidised bed of the solids; an electrical field is produced in the fluidised bed by contact electricity and/or the porous floor acting as an electrode, while the extraction tray at the top of the fluidised bed constitutes the second electrode. The second electrode components of the extractor tray is insulated on the underside but uninsulated on the upper side. This largely prevents the additional extraction by the top tray of a proportion of those particles of opposite polarity from the set of particles extracted by this tray.

Title: Reducing radial force variations in tyres - by hot stretching eccentrically and cooling under pressure
Inventor: ZIERMANN KONRAD DIPL PHYS DR
IPC: B29D30/06
Filed: 1972-12-06
Abstract: A mould, to accept the pneumatic tyre, is enlarged radially and therefore eccentrically outwards over a segment which embraces 160 degrees at the centre in the plan view. The tyre is placed in posn. and stretched outwards at that segment by applying water pressure of 10-25 atmos. at 140-200 degrees C. After 2 mins. the tyre is cooled under 10 atmos. The radial forces are thereby increased in the segmental zone where they were originally minimal, and are therefore now altogether within an acceptable tolerance.

Title: Monitoring fuel ball pneumatic transport - using change in feed tube pressure caused by ball to give ball count signal
Inventor: FABER RALF
IPC: B65G51/36
Filed: 1973-09-01
Abstract: Continuous monitoring of fuel element balls in nuclear plant during pneumatic transport in feed tubes loaded with a conveying gas. The balls are charged into the tube singly so that the change in effective pressure can be measured by a venturi arranged in the gas inlet together with an integrated differential manometer. The measurement is converted into an electrical signal. The signals are used to count the number of balls fed into the tube, whilst the period of the pressure change provides information on ball behaviour in transit. The effective pressure on a time basis during ball transit should be recorded and displayed by an oscillograph memory.

Title: Ultrasonic generator - reflecting radially inwardly direct ultrasonic waves with electromechanical transducer around outside of metal ring
Inventor: MORI EIJI PROF
IPC: G10K11/32

Abstract: The electromechanical transducer of the ultrasonic generator is fastened to the outer perimeter of the metal ring and excites the ring to resonance vibrations which are reflected into the empty interior of the ring so that the metal body vibrates radially with an acoustic resonance frequency. It is possible for several ultrasonic generators to be connected together by tubes which are embedded in circular grooves formed in the adjacent end faces of the metal rings. The tubes are connected to the rings at an oscillation or vibration joint of the radial vibration of the ring so that material which is capable of ultrasonic vibration can be moved longitudinally or axially through the tube and the ring. The outer perimeter of the ring(s) may have the shape of a regular polygon, with each transformer fastened to a surface corresponding to one side of the polygon.

Patent DE-2402634-A1 (DE)
Title: Safety belt take up reel - has two spiral springs arranged in series to become consecutively operational
Inventor: PENZKOFER FRANZ
IPC: B60R22/405
Filed: 1974-01-21
Abstract: The requirement that the pull experienced on the operating ball during its use should be as uniform as possible is envisaged with the present arrangement. There should be some spring reserve in the take up reel even after the belt is completely taken up when not in use. On the other hand the pull on the belt should not be excessive when it is taken out during use. A ratchet arrangement operated by a steel ball guided in a trough with pitched bottom becomes operative at a sudden deceleration of the vehicle due to the ball surging forward, deviating the ratchet arm into engagement with the ratchet teeth and causing the axle of the reel to rotate against the delaying force of the spiral springs.

Title: Gas-tight two-part firing pin - has impact mandrel with lubricant channels and sealing cone
Inventor: POLITZER ANTON DIPL ING
IPC: F41A19/13
Filed: 1974-02-07
Abstract: Firing pin for firearms without cartridges comprises an impact mandrel with lubricant channels which at the loading chamber end ends in a sealing cone which abuts against a wall and at the other end protrudes into a lubricant chamber. A cup spring in this chamber engages the mandrel. The impact-transmitting pin protrudes into the lubricant chamber from the other side. The firing pin can be manufactured in short length and of reduced weight. A good close, firm working is reached since the firing pin rapidly returns to the rest position after the firing point has been reached. Tears on the endangered cross-sections of the pin caused by recoil on the breech plate are avoided. It is kept free of firing remains.

Title: Sound broadcast receiver - has numerical frequency display operated by periodic counting of input frequency by electronic counter
Inventor: KLANK OTTO
IPC: H03K21/14
Filed: 1974-02-14
Abstract: The receiver has a quartz crystal oscillator serving as the time base, and a circuit producing the necessary control functions. In order to display, if required, the clock time instead of the received frequency, a second electronic counter is provided, and can be connected to the decoder and the display device. Each counter reading can be transferred in series by shifting pulses to a common main store in the decoder, and the corresponding digits displayed in series. The second counter has a feed-back so that the reading transferred by the shifting pulses to the main store, is alos supplied at the same time to the second counter. Thus its reading is restored in the counter after its transfer to the main store.

Title: Activated sludge effluent treatment - using an after-clarifier with a stabilised sludge compaction zone and constant sludge recycling
Inventor: ALDAG WILHELM DR
IPC: C02F3/12
Filed: 1974-05-30
Abstract: In the wholly biological purification of effluents from sludge and impurities by (a) compaction of these materials in a rising flow in hopper or channel-type after-clarifiers and (b) sucking away and recycling of these materials to the activated sludge tank using the height-adjustable pumps and pipes or other aggregates and forces, (c) the recycling takes place via at least two superimposed openings or removal positions, one of which lies below the compaction zone though spaced from the tank bottom and has a greater recycle capacity e.g. by having a greater nominal dia. than that of the pipe lying within the compaction zone. Gives an improvement in the 5-day BOD value equivalent to an increase of purification from 92% to 98%.
