Title: Multi-processor calculating system with flexible topology - has individual and independent control of different processing operations
Inventor: DAVIES JACK L
IPC: G06F9/38
Filed: 1974-11-19
Abstract: The multi-processor calculating system has a flexible topology and individual control of the various processing operations as desired. The system comprises a central calculating unit, a central control, a program store, and data inputs as well as data output units. The central calculating unit has a number of different processors (arithmetical modules AM1 to AM13). These processors can be connected with each other in selected series of rows and with the data input and output units at least in a group fashion from pulse to pulse by continuous data flow. The path is from the central control via channel selectors. Simultaneous control of the processing operations can be carried out independently and individually. Several such operations take place in a working store as parallel-time multiplex operation without intermediate storage.

Title: Living tree trunk thickness measurement - using nondestructive oscillations involves use of resonant peak bands for spotting of rotted trees
Inventor: SCHUELER MANFRED
IPC: G01N29/12
Filed: 1974-12-06
Abstract: A non-destructive method of testing the thickness of living trees, imposes mechanical oscillations on the bark of the tree trunk. The oscillations of the tree trunk are sensed by an acoustic microphone, and are fed to an amplifier and suitable indicator. With trunks having rotten interiors there are additional oscillations in the low frequency range. An oscillator in the 100 to 10000 Hz range is used and the measurement part includes an amplitude indicator following an amplifier. Bands of resonant peaks are produced by rotten trees giving an low frequency band.

Title: Sludge filtrate purificn. - in first basin part sepd. by flilterplate from second with spray nozzle water pump
Inventor: BAEHR ALBERT
IPC: B01D29/00
Filed: 1975-06-05
Abstract: Filtrate, produced during the dewatering of sludge, e.g. in sewage treatment plant, is purified by passing in into one of two compartments, sepd. by a filter plate in a basin. Deposited sludge is periodically recycled by a pump. Another pump in the other compartment for purified filtrate produces water for spray nozzles. Some of them are directed against the filter plate to keep it clean. This reduces the consumption of fresh water very greatly with very simple means. The efflux is clean enough to meet all regulations regarding pollution.

Title: Discharge valve of railway tanker wagon - has hydraulically assisted manual actuation with eccentrc shaft positioning piston
Inventor: KRAMER ROLF DIPL ING
IPC: F04B9/14
Filed: 1975-07-09
Abstract: The railway tank wagon has manually-actuated, hydraulically-operated discharge valves. Two hand wheels on shafts (31) can be axially moved to engage a coupling (4) with the eccentric shaft (3). The eccentric shaft is linked to a piston (1) through a connecting rod (2). The position of the hand wheel shaft (31) determines if integral check valves are open or closed. This is achieved by linking the valve piston to the coupling (4) of the hand wheel shaft. The hydraulic flow from the oil reservoir to the discharge valve is thus governed by the position of piston (1) and the check valves.

Patent DE-2534102-A1 (DE)
Title: Rapid starting static converter - particularly for standby supplies provides full power with minimum start up time and uses batteries for energy store
Inventor: UDVARDI-LAKOS JANOS DIPL ING
IPC: H02M7/517
Filed: 1975-07-30
Abstract: The static converter circuit provides its full output power with a correct phase relationship to the supply which it will be replacing in a very short time. During normal supply periods energy is stored to be fed into the load system, and when priming or firing signals are allowed through to the inverter by interruption of the normal supply, the inverter is supplied by some standby d.c. source such as batteries providing both polarities. This ensures that the correct polarity is available at the instant of switching. Switching is by electromechanical relays, thyristors or triacs (Tr1, Tr2), the switching operation being synchronised from sensors in the switching network.
Patent DE-2537662-A1 (DE)
Title: Concrete stressed tendon anchorage and connection - has pitch of softer anchor thread exceeding that of bar thread
IPC: E04C5/16
Filed: 1975-08-23
Abstract: The anchorage system for bar-shaped stressed tendons (2, 3) as used in stressed concrete, or other similar tensioned rods consists of cutting a thread which can mesh with an anchoring unit with a counter-thread cut in it. The anchoring unit is made of material less rigid than that of the tendon member, and the pitch of its thread is slightly greater than the pitch of the thread on the tension member. The tension rod thread may be an intermittent thread made up from ribs lying on a helical line. This system helps to reduce stress peaks, and spreads out the transmission of forces from a tension member onto the anchoring unit. The difference in relative tooth position changes by a constant increment with turns of thread.
