Title: Arrangement for operating an electrochemical energy storage device
Inventor: URSTOGER RUPERT
IPC: H01M12/08
Filed: 1984-07-23
Granted: 1987-05-07
Abstract: In an electrochemical storage device such as a zinc-bromine or zinc-chlorine accumulator containing groups of electrochemical cells connected in series to a load, nonuniformly distributed deposits of the active electrochemical material on the electrodes are removed by a complete discharge of the cells. While the storage device energizes a principal load, the cell groups of the storage device are discharged in a cyclic sequence via an auxiliary load and disconnected from the series circuit of the cell groups no later than the time at which the respective cell group has attained its operational use limit. The disconnected discharging cell group is further discharged via the auxiliary load until the nonuniformly distributed deposits on the electrodes of the cell group are totally removed. The cell group is then recharged and reinserted into the series circuit of the cell groups or, alternatively, reconnected to the series circuit and then recharged. The method of operation enables the energization of a load by the storage device while the device is being regenerated.

Title: Process for the preparation of polyimide and polyisoindolo-quinazoline dione relief structures
Inventor: AHNE HELLMUT DR
IPC: G03F7/027
Filed: 1984-12-12
Granted: 1988-04-28
Abstract: Highly heat resistant polyimide and polyisoindoloquinazoline dione relief structures can be produced by applying radiation-sensitive soluble polymer precursors in the form of a film or foil on a substrate, irradiating the film or foil through negative patterns with actinic light or electrons or a light, electron, ion or laser beam, removing the unirradiated film or foil portions and optionally by subsequent annealing. The relief structures are produced in an inexpensive manner with high purity and in a chloride-free form as well as having economically acceptable exposure times as a result of using as polymer precursors poly-condensation products which are prepared in the presence of carbodiimides. The polycondensation products are prepared from diamino compounds or diamino compounds having at least one orthopositioned amido group and olefinically unsaturated tetracarboxylic acid diesters of aromatic and/or heterocyclic tetracarboxylic acid dianhydrides and olefinically unsaturated alcohols. The relief structures produced by the method according to the invention are suitable in particular for use as resist, surface protection, and because of the high purity as durable protective and insulating material in the semiconductor field.

Title: Coin checking apparatus
Inventor: PARTRIDGE DAVID

Filed: 1984-10-30
Granted: 1989-08-31
Abstract: A coil 1 is wound on a former 2 having a central opening 4 of a shape corresponding to the outline of a coin 3 to be checked and mounted with the plane of the opening at an angle to the horizontal. The opening 4 has, towards its lower side, a cross member 6 located below the transverse centre line of the coil 1 so that a coin 3b can momentarily rest on the cross member with its plane in the plane of the coil and can then turn about the cross member under its own weight and pass edge-wise through the opening in the former. A coin guide 10 guides coins edge-wise in a generally vertical direction towards the lower side of the coil so that a coin emerging from the guide enters the part of the opening 7 in the former 2 on the side of the cross member 6 away from the diameter and then turns about the cross member into the plane of the coil, at which point an output signal dependent on the characteristics of the coin as a whole is obtained. A lever 12 is included for clearing jammed coins.

The ratio of the individual amino acids in the flagellar antigen of the individual H-serotypes is stated. For producing the polydisperse native Pseudomonas flagellar (H) antigens (FAg) methods are indicated, wherein Pseudomonas aeruginosa bacterial cultures or fractions thereof are treated with a detergent and the flagellar antigens are separated from the cultures. Prior to treatment or in the presence of the detergent, the bacterial culture is subjected to a shearing procedure, i.e. exposed to shearing forces. Thereafter, the flagellar antigens separated from the bacterial mass are isolated by a chromatographic treatment. For this chromatographic treatment a molecular sieve can be used and a further purification by chromatography on a column can be carried out for obtaining flagellar antigens of high purity.
