Title: Classification of mixts. in centrifuges - using system with double coupling to two bowls and spring suspension to balance out imbalance when the bowl is at speed
Inventor: BALSTER HUGO DIPL PHYS DR
IPC: B04B9/12
Filed: 1979-03-13
Abstract: Finely divided pumpable materials e.g. with a liquid component are sepd. in a centrifuge bowl which is supported on one side. The heavier component is sepd. out by the centrifugation process due to differences in specific gravity. During or after the centrifugation, any deviation or inbalance of the bowl due to the distribution of weight inside it is compensated for. If the amt. of material which has to be removed is large and an excessive braking force is needed on the bowl, this energy can be absorbed by an adjoining bowl by a spring clutch drive mechanism to conserve the rotational energy of the bowl. Used for sepg. mixts. contg. fine divided solids etc. The system allows the bowl to locate its own gravitational axis of rotation and thus balance out no matter how loaded. This allows the application of higher centrifugation loads.

Title: Electrical warp-stop motion - activated by contact of heald wires with conducting heald rail in bottom shed position
IPC: D03D51/32
Filed: 1979-05-30
Abstract: A warp stop motion for looms comprises heald rails having two conductive sections sepd. by a layer of insulation which can be electrically connected by the heald wire resting across the top edge of the rail. The rail forms part of a control circuit having a condenser which is charged whilst the heald shaft is raised, and discharges when the shaft is lowered and the heald wire is lifted from the rail by the warp yarns. The circuit includes a counter which re-sets the device after each trip, and which stops the loom only after a pre-set number of repeated trips. No mechanical connections to the shedding motion are required to determine the position of the heald shaft, and the device does not respond to accidental trips due to oscillations of low-tension ends. It is simpler and less expensive than existing designs, and operates reliably at high speeds.

Patent DE-2930085-A1 (DE)
Title: DC converter for stabilised power supply - uses component of output current to produce auxiliary control voltage
Inventor: KLOTZ HERMANN DIPL ING
IPC: H02M3/155
Filed: 1979-07-25
Abstract: A converter produces a stabilised power supply reducing the losses which may arise in the switching transistor (1). A transformer (7) is connected with its prim. winding (8) in series between the switching transistor and the rectifier coupled to the output terminal (UA). As the stabilised voltage is generated by operating the switching transistor to a controlled mark-space ratio a voltage is induced in the transformer sec. winding (9). The transformer output is rectified (11), smoothed by a capacitor (12), and added to the unregulated input voltage (UE) applied to the driver transistor (5). The effect is to increase the current applied to the base of the switching transistor when the control transistor is turned on by the controller (S,4). The switching transistor is thereby made to operate fully saturated thus reducing losses. As it is normal to include a smoothing choke in the output, the substitution of a transformer adds little to cost or complexity of the circuit.

Title: Laser anemometer for flow speed detection - uses laser light pulse train for illumination of flow suspended particles under electronic control
Inventor: BAYERER REINHOLD DIPL PHYS
IPC: G01P5/00
Filed: 1979-09-13
Abstract: The flow velocity in high speed flow fields is determined by a contactless process, using laser light for illuminating particles, introduced into the flow field, under different motion conditions. The light dispersed by the particles is recorded. The particles are illuminated by a train of laser light pulses of known time intervals, generated by an electronic quality control of the laser. Pref. a pocket cell is used for the laser control. A solid state laser may be used, and its pulsed beam may be fanned out in a beam plane which may irradiate the measuring plane in an intersecting manner. During the quality control, at least one pulse in the train may obtain a different intensity. The time interval of the pulse train may be calibrated. A solid-state laser stroboscope is used in the process, whose pulses are transmitted into the measuring region by beam light guides.

Title: Differential polarography system - applies ramp voltage with modulated square pulses to drops of long dropping time
Inventor: GAJDA VLADISLAV
IPC: G01N27/48
Filed: 1979-12-28
Abstract: Differential pulse polarography method uses growing Hg drop on working electrode with dropping time of several 10 secs. Few seconds after fall of preceding drop, polarisation ramp voltage is applied with superimposed modulating rectangular pulses at frequency of several pulses per sec. Measurement is taken after second drop has fallen. Applying drops with long drop time reduces time required for analysis and results in lower Hg consumption. Measuring on drop with large surface improves sensitivity, and gives very accurate and reproducible results.

Patent DE-3015827-A1 (DE)
Title: Testing digital data transmission system for faults - by short circuiting line at successive repeater positions and sending test signal
Inventor: POSPISCHIL REGINHARD DR ING
IPC: H04B17/40
Filed: 1980-04-24
Abstract: Digital data transmission lines are tested by a relatively small addition to the circuitry in repeater stations. At each end of each repeater a short circuit (SS1,SS2) can be applied across the send and transmit lines. For this purpose each repeater has two identical regulator units (Reg1,Reg2). Each has receive (EAZ1,EAZ2) and output amplifier (V1,V2) sections. Connected to each receive section is a command pulse evaluator (KE1,KE2) whose output is connected to a conditional counter (ZZ1,ZZ2) and also, to pass on a command, to the output amplifier. The inputs to the conditional counters are interconnected. The counter (ZZ1,ZZ2) output orders the condition of the repeater, and can order closure of the short circuiting switch. It is arranged that a short circuit command is only acted upon the second time that the command is received. The correctly timed arrival of a command from the opposite direction can suppress action. By these means a specific repeater on the system can be selected to apply the short circuit whilst keeping all repeaters identical.
