Title: Monitoring instantaneous accumulator capacity - measuring terminal voltage using voltage-to-time display indicator matrix
Inventor: PREUSS PETER DIPL ING
IPC: G01R31/36
Filed: 1980-07-03
Abstract: A circuit tests the capacity of accumulators by measuring the terminal voltage during discharging. The necessity of replacement of a battery owing to declining efficiency is detected in good time. The terminal voltage is measured and stored at defined time intervals whilst the accumulator is being discharged at constant current. The amplitudes of the stored values are displayed against time. All stored values are displayed simultaneously. Timing pulses of constant periodic duration are produced by a controller and used to drive successively the columns of a matrix of indicator elements (66) whose lines are driven by a signal derived from the battery voltage. The indicator elements receiving both voltages are lit to show a given level at a given time.

Patent DE-3120415-A1 (DE)
Title: Device arranged on the vehicle roof of cars and intended for covering the body
Inventor: BIERWIND WOLFGANG
IPC: B60J11/00
Filed: 1981-05-22
Abstract: The object of the application is a device for covering bodies of cars to protect them against the effects of the weather. The device is in the form of an aerodynamic hood which is arranged on the vehicle roof and contains at least four webs which can be pulled out of slits on the longitudinal and transverse side and can be connected to one another at the wings spread out from the sides of the webs by a zip fastener or the like. In the hood, the webs are rolled or gathered up on spring or gathering blind mechanisms. The blind mechanisms are self-locking. At their ends, the webs are provided with closure plates which close the slits when the webs are reintroduced into the hood. The spreading of the webs to form the wings takes place by using a transversely extensible fabric or by folding the wings which can be let down. The hood is attached to the vehicle roof or is integrated into the vehicle roof. <IMAGE>
Patent DE-3132226-A1 (DE)
Title: Arrangement for detecting and cancelling ghost signals in a television signal
Inventor: HOLMES DAVID DUNLAP
IPC: H04N5/21
Filed: 1981-08-14
Abstract: In this arrangement, the horizontal synchronisation pulses of a first sequence of lines of the vertical retrace interval are used as reference signals for detecting and verifying the existence of a ghost signal. This detection process leads to the generation of a signal which reliably indicates the position of the ghost signal in time with respect to the main television signal. The position indicating signal is then used for selecting the appropriate tap of a tapped delay line (290). The video signal taken from the tapped delay line is supplied to the control amplifier (302, 312) of a ghost signal cancelling device in order to generate a pseudo ghost signal during one or more subsequent lines of the vertical retrace interval. The pseudo ghost signal is combined with the original video signal in a combining circuit (320) in order to cancel the ghost component. The detection and cancelling of ghost signals is rapid and accurate due to successive ghost signal detection and cancelling over a number of lines of the same vertical retrace interval. <IMAGE>

Title: Process for recovering sulphuric acid from waste waters
Inventor: WINSEL AUGUST PROF DIPL PHYS D
IPC: H01M10/08
Filed: 1982-02-03
Abstract: A process for recovering sulphuric acid from waste waters makes use of the operating principle of the lead storage battery, in accordance with which the sulphuric acid electrolyte participates directly in the cell reaction. In order to bind the sulphuric acid selectively as lead sulphate by a discharge process, it is even sufficient to supply the waste water containing sulphuric acid to an electrolytic cell in which only one of the two electrode polarities of the lead storage battery (Pb or PbO2) is present, paired with a reversible H2 or O2 electrode as counterelectrode. After interrupting the flow, the sulphuric acid is liberated from the lead sulphate by recharging the cell (regeneration) and is able to pass through the manufacturing process again.

Title: Method for measuring the internal pressure of mass-produced products which are located in containers and in which pressurised gas has to be held
Inventor: SHIMA YASUYUKI
IPC: G01M3/24
Filed: 1982-03-20
Abstract: This invention relates to a method for establishing defective fuel rods (1) in a nuclear fuel assembly. The internal gas pressure of a defective fuel rod (1) is very much lower than that of a normal fuel rod (1), and as a result of this fact there is a drop in the natural frequency of the vibration in the interior of the tube jacket (2) enveloping the fuel rod (1). In the present invention, the natural frequency of the tube jacket (2) is measured in order to detect a defective fuel rod (1). This invention also relates to a method for establishing "inferior" pressurised nuclear fuel rods (1) when testing after production. The method can be applied in non-destructive detection of "inferior" containers for items which must have pressurised gas in the interior. <IMAGE>

Title: Ignition circuit for thyristors connected in antiparallel
Inventor: KONISHI SHIGEO DIPL ING
IPC: H02M1/096
Filed: 1982-03-22
Abstract: The invention relates to an ignition circuit for a thyristor arrangement in which two branches having at least two thyristors (TH1, TH3 and TH2, TH4), connected in series in the same direction of conduction, are connected in antiparallel. The ignition circuit contains a photo-ignitable auxiliary thyristor (PTH1), one terminal of which is connected to the junction between two diodes (D1, D2) connected in series in the opposite direction of conduction. The second terminal of the photo-ignitable auxiliary thyristor (PTH1) is connected to a line (L) which connects corresponding junctions of the thyristors (TH1, TH3 and TH2, TH4) of the antiparallel-connected branches. All thyristors (TH1 to THn) are ignited via the photo-ignitable auxiliary thyristor (PTH1) and the diodes (D1, D2). Thus only one photo-ignitable auxiliary thyristor (PTH1) is required for igniting several thyristors (TH1 to TH4). This is only loaded with the voltage from one of the thyristors (TH1 to TH4). <IMAGE>

Title: Device for feeding bulk material into a pneumatic pressure-conveying installation
Inventor: STEGNER MATHIAS
IPC: B65G53/46
Filed: 1982-03-30
Abstract: For feeding bulk material into a pneumatic pressure-conveying installation (1), use is made of a squeeze-valve sluice chamber (5) which is connected directly by way of its outlet opening (8) or with interposition of a metering device to the pressure-conveying installation (1) and the supplying opening (4) and outlet opening (8) of which can be closed by means of pivotable closure flaps (3, 9). Arranged inside the sluice chamber designed in the manner of a squeeze valve is a squeeze-valve tube (7) which can be supplied from outside with a pressure medium in order to displace the chamber volume as soon as the closure flap (9) of the outlet opening (8) has been opened. A backflow of the pressure-conveying medium from the pressure-conveying installation (1) through the sluice chamber (5) is thus prevented. <IMAGE>
