Title: Sealed maintenance-free battery with nickel oxide and metal electrodes - having conductive, coarse-pored gas diffuser outside each metal electrode
Inventor: BENCZUR-UERMOESSY STUTTGART DI
IPC: H01M10/34
Filed: 1979-02-24
Abstract: Sealed, maintenance-free cell or battery has Ni oxide cathodes, a fine-pored, gas-impermeable separator, metal anodes with negative charge and discharge reserve and fixed alkaline electrolyte. The novelty is that the side of the anodes way from each cathode is coated with an electrically conductive, coarse-pored gas diffuser in electrical contact with the anodes. Gas diffuser can consists of C, graphite, Ni- or Cu-plated C, Ni, Cu or steel felt, foamed C, Ni or Cu-plated open-cell organic foam or coarse-pored sintered Ni, Cu or Fe. A Cd, Co, Fe or Zn anode is used. With gas diffusers of large area in bipolar batteries, the electrodes are round discs giving optimum packing of the surface area and the separator is provided with holes across the cavities between the discs, the electrodes stack being kept under pressure acting perpendicular to the surface. Rapid O2 conversion is possible. The range of application is extended to include unipolar and bipolar Ni/Co, Ni/Fe and Ni/Zn cells.

Title: Confectionery moulding box emptying machine - with upturning mechanism on endless belt
IPC: A23G3/02
Filed: 1979-05-15
Abstract: A machine for the upturning and emptying of moulding boxes in the manufacture of confectionery includes a mechanism which grips the moulding box as it arrives and turns it through 180 degrees. The box is raised enough to allow its content to be moved on to another belt conveyor when an endless belt in the upturning mechanism is turned ON. The empty moulding box is then raised to another conveyor. This machine requires a minimum stoppage for the belt conveyors and works at a fast upturning rate.

Title: Swimming aid with handle and inflatable bodies - has easily accessible eccentric which turns to open and close locking mechanism
Inventor: HECKERT GERHARD
IPC: A63B35/06
Filed: 1979-10-03
Abstract: The swimming aid has a handle and inflatable bodies with a retaining rod running through each and fitted at the end with discs. Each disc contains a retaining spring which has two straight ends. Each disc has a rotatable eccentric. The straight ends of the spring adjoin the eccentric faces of the eccentric under tension. The retaining spring engages with the annular groove of the relevant stud located in an intermediate member when the spring touches the eccentric faces with a small radius from the longitudinal axis of the eccentric but is out of engagement when the spring touches the eccentric faces with a large radius. It is thus now possible to lock and unlock the retaining rods merely by rotating the eccentric, to widen the spring.
Patent DE-2940395-A1 (DE)
Title: Input circuit for DC and AC voltmeter - has amplifier with high input resistance whose output goes partly to inverting input of second, operational amplifier
Inventor: DITTMANN KARL-HEINZ
IPC: G01R19/00
Filed: 1979-10-05
Abstract: The first amplifier (1) of the input circuit has a high input resistance. Its output signal is supplied on one hand to a summation point (2), via a resistor (R6), and on the other hand to the inverting input of a second operational amplifier (5). The latter output is coupled to a terminal of a diode (6) whose other terminal is connected to the summation point via a second resistor (R9). This diode terminal is connected to the inverting input of the operational amplifier via a negative feedback resistor (R5). The circuit is so rates that with the diode in conductive state the current (I2), flowing across the second resistor, is approximately twice as high as the current flowing over the first resistor. Preferably the first amplifier is also of operational type and has several negative feedback resistors which can be selectively switched. Thus the output signal polarity is independent of that of the input signal.
Patent DE-2942116-A1 (DE)
Title: Mast guided pile-driver support and safety mechanism - has controlled stop release movement as rammer travels upwards
Inventor: KEHRBERGER ACHIM ING GRAD
IPC: E02D13/04
Filed: 1979-10-18
Abstract: A blocking toggle or more than one, on the mast, is movable against return spring action into a stop position, and released so as to return automatically to its free position, in a depositing device for supporting a pile driving rammer, in a raised position on the mast. The blocking toggle (36,38) is regulated back into its release position, against the action of the activating eye and cable device (74,76), by the rammer being moved upwards from the bottom, by the action of the toggle which has been moved into its stop position. Curved units may be used for this adjustment. The depositing device cannot be damaged by a rising rammer once the blocking toggle is set in the stop position.

Title: Screening process for empty reusable beer barrels - uses gas identification to check if suitable for subsequent gas refilling
Inventor: EULER HANS-DIETER
IPC: B08B9/08
Filed: 1980-03-07
Abstract: Before the re-usable barrels are refilled with beer under pressure they are tested for suitablilty. To this end the propellant gas which remains in the vessel after emptying is measured for the purpose of identification and on detecting an ideal gas e.g. carbon dioxide the vessel is released for the subsequent cleaning process but if a foreign gas is detected the vessel is siezed and handled separately. This system is based on the idea that an identification of the propellant gas which has been used to empty the vessel and which now remains in same provides a clear indication as to whether the vessel is suitable for refilling following the subsequent cleaning process.

IPC: A61J1/20
Filed: 1980-04-09
Abstract: A pipetting device for bottles and vessels comprises a cap with outwardly projecting suction components equipped with a gripping length and inwardly projecting suction pipe having an open end inside the bottle. This suction pipe (4) has grooves (10) at the end nearest the cap, to form a firm connection with the elastic suction component (3) outside the cap. The dia. of the suction pipe (4) at the end nearest the cap is smaller than the external dia. of the external suction component (3) but slightly larger than its clear internal dia. so that the grooves (10) press elastically into the inner wall of the suction component. The grooves may be in the form of a continuous thread, or separate rings. Alternatively, they may extend only around part of the circumference, typically grooves may be offset from one another by 180 degrees. Used for dispensing medicaments from bottles, e.g. for nose or ear treatment. Mfg. tolerances between the pipetting device and the bottle are compensated, but at the same time hard plastics materials having a glass translucency can be used without risk of damage.

In the flap's (2) closed position, the support can swivel into the ring mounting aperture. The support may be held on the hinge side (11) of the ring while the cable had a damping spring (6) integrated in it. This permits control of opening angles up to 180 degrees.
Patent DE-3020745-A1 (DE)
Title: Direct voltage transducer - has remote controlled switching and chokes which return remanent magnetic energy to supply
Inventor: LECHLER SIEGFRIED ING GRAD
IPC: H02M3/337
Filed: 1980-05-31
Abstract: The storage inductors are non-magnetically coupled chokes (L1,L2) which are charged in anti-phase by the action of two electronic switches (S1,S4;S2,S3). The immediately connected switches (S1,S2) are shunted by primary windings (W3,W4) of an auxiliary transformer (Tr2) whose secondary windings (W5,W6) are connected to the primary dc supply (Ue) such that the remanent energy is the chokes is alternately returned to the supply. The electronic switching is timed to give an overlap during which one choke is discharging into the load and the other is rapidly charging from the supply. At the end of the overlap the newly charged choke begins to discharge into the load. At the same time the already discharging choke is made to continue its discharge into one primary winding of the auxiliary transformer thus returning its remaining energy to the supply. There is no abrupt switching on the primary or output side of the transducer thus reducing the harmonic content of the voltages.
