Patent DE-2630759-A1 (DE)
Title: Integral clock pulse regeneration circuit - retransmits regenerated bit without delay ending with end of corresponding clock pulse
Inventor: SCHETT OSKAR
IPC: H04L7/027
Filed: 1976-07-08
Abstract: Clock signals are regenerated from transmitted bits from which approx. rectangular pulses are derived by threshold switches. A delayed clock pulse train is derived by a clock pulse extractor with pulse repetition frequency equal to the fundamental frequency of the received bits. The incoming bits are scanned by this clock pulse train at the approx. middle of the bits, and the regenerated bits are retransmitted through a timing switch. Retransmission of individual bits begins without delay with the beginning of bit scanning, and ends with the end of the corresponding clock pulse.

Title: Automatically calibrated radionuclide detector - using window position identified from characteristic shape of energy spectrum
Inventor: MICHEL LOTHAR DR ING
IPC: G01T1/40
Filed: 1976-09-15
Abstract: Measurement assembly operates by counting the number of radiation events of a nuclide in an energy range, which contains a characteristic maximum of the number of events for the nuclide, and comprises a receiver which emits a voltage pulse dependent upon the energy of an event. Every voltage pulse possessing a value lying within the relevant range (i.e., characteristic of the energy range) adds 1 unit to a value contained in a counting device. Used both for medical and industrial use. The appts. enables frequent recalibration to be dispensed with, once calibration has been carried out; any further deviations in the parameters can be regularly detected during use.

Title: Moving belt position sensing appts. - has laser beam grazing edge of belt and reaching photoreceiver whose output signal controls belt position
Inventor: JOUAULT PIERRE A
IPC: B65H23/02
Filed: 1976-09-29
Abstract: The appts. senses the edges or midway position of a workpiece esp. a belt driven over end drums. A laser arranged in a nominal position above the belt projects a laser beam in the region of the belt edge. The intensity of the laser beam which is not adsorbed by the belt edge is taken up by the receiver and the receiver signal is converted in a control signal. The control signal activates an adjustment of the end drum position or alteration of the drum speed or a mechanical and hydraulic displacement of the belt to its nominal position.

Title: Solar collector based on Glauber's salt contg. borax - thickened with amorphous silica, preventing storage capacity loss through sedimentation
Inventor: GRUBMUELLER GEORG
IPC: C09K5/06
Filed: 1976-09-29
Abstract: Solar collector system uses Glauber salt, Na2SO4.10H2O, as latent heat store, with the addn. of borax as crystallisation nucleating agent and a thickener. The Glauber salt contains 2-7, (3-4)% amorphous SiO2 with a particle size is not >20 nm. as thickener and 20% excess water. This thickener prevents sedimentation into a lower layer of dense anhydride, a middle layer of Glauber salt and an upper layer of satd. soln., which reduces the storage capacity of the Glauber salt. Its action depends on the formation of a hydrophilic gel when the Glauber salt melts. Unlike conventional thickeners, it does not undergo ageing, since the excess water forms a protective sheath. At a particle size of is not >12 nm., the excess water content of 8-10, esp. 9% and at is not >7 nm., 3-5 (4)% is pref.

Title: Hydrogen recovery from gas mixts. - by controlled adsorption of impurities on carbon and desorption by evacuation
Inventor: JUENTGEN HARALD PROF DIPL CHEM
IPC: B01D53/04
Filed: 1976-11-03
Abstract: Removal of H2 from gases also contg 5 vol.% N2 and/or CO, well as CH4 (and opt. other hydrocarbons), CO2 and minor impurities, is effected by passing the mixt. through a column packed with a carbon adsorbent, so that the CO2, hydrocarbons and minor impurities are adsorbed in the part of the column near the inlet (zone 1) and the N2 and/or CO are adsorbed in the part near the outlet (zone 2), while purified H2 is withdrawn from the outlet. The adsorption phase is terminated when zone 1 extends over >=30% of the height of the column but before N2 and/or CO appear at the outlet. Then, a vacuum is applied to the inlet to desorb the gases adsorbed in zone 1, which is simultaneously purged with N2 and/or CO (and residual H2) desorbed from zone 2. Process can be used to recover 99.9% pure H2 from partially purified coke-oven gas or gases from steam-reforming, catalytic reforming or cracking plants, etc. A separate purge gas system is not required.

Title: Short circuit detector and indicator for three-phase networks - compares charge currents in actual and simulated line-earth capacitances
Inventor: WIENER ERNST
IPC: G01R27/18
Filed: 1977-03-24
Abstract: The short-circuit detection and indicating system for three-phase networks with isolated or inductively earthed neutrals, operates by comparing the polarity of the first half-cycle of the charge transfer current in the neutral line-earth capacitance with the polarity of the first half-cycle of charge transfer current in simulated line-earth capacitance. The respective currents and their polarities are detected via transformers connected to pulse circuits. The outputs of these are connected to AND-gates and to a four-input OR-gate. The output of this is delayed and drives a monostable. One or other of two OR-gates gives a pulse to switching amplifier which energises a holding relay and corresponding signal lamp to indicate whether the short-circuit is in the direction of the line or the bus bar.

Title: Laminated moulded plastic parts - produced from prepreg in heated chamber of moving tool belts
Inventor: OLBRICH KURT
IPC: B29C44/30
Filed: 1977-06-29
Abstract: Laminated moulded parts are produced of plastics by passing an endless prepreg between the four tool belts of a draw/press and hardening section which form a chamber. The prepreg strip is formed to a hose which is pressed against the tool belts and a hard foam resin is injected in the cavity. Heating hardens the prepreg and the moulded part produced is finally cut to length. This produces high-quality moulded parts or profiled sections, contg. a glass-fibre reinforced plastic, with little technical effort.

Patent DE-2801986-A1 (DE)
Title: Measuring play of nut and spindle drive for control rod - by change in field produced by magnet on nut
Inventor: ASTE INGVAR
IPC: G01B7/00
Filed: 1978-01-18
Abstract: Measurement of the play between a drive nut of non-magnetic material and a drive spindle is described for a control rod drive mechanism, in which the nut is free to move axially in a sleeve which prevents it from rotating, but is limited in its axial movement by a stop surface. A special drive mechanism is fitted to the spindle and is used for rotating it until the nut meets the stop surface; an emitter forming part of an indicator for magnetic field intensity is then placed outside the sleeve and close to a permanent magnet fixed to the nut; the spindle is then rotated in the opposite direction until the indicator indicates a change in the field intensity, which is evidence that the magnet and therefore the nut has now moved. The angle of rotation of the spindle which has occurred in this reverse direction is then measured and from this the play is calculated. Used in control rod mechanisms, where the nut typically is made of graphite, the wear is so high that about 20% of the mechanisms need replacement each year. The method enables the amount of play resulting from the wear to be determined without dismantling any part of the control rod drive mechanism.

IPC: F16H25/20
Filed: 1978-04-03
Abstract: Electromech. load handling mechanism has a telescopic arm (4) within which one or more worm drives are located and driven from brakable electric motor (80). At least one worm shaft has ball runners which convert the rotation of the shaft into a reciprocal motion of the telescopic arm (11).

The reciprocal telescopic arm (11) is non-rotatable with the fixed part (4) and the application of the drive motion to this is cushiond by spring pockets in both directions. The construction reduces the physical size of all load bearing parts.
