Title: Measuring pull in conveyor chains during operation - using measurement link strain gauges and moving telemetry unit
Inventor: ROTHACKER HARRY
IPC: G01L5/10
Filed: 1980-10-28
Abstract: The arrangement is for measuring the pull of rotating supply chains and contains a measurement chain element arranged to be object to the fore of the supply chain. The measurement element is terminally elastic and has an associated arrangement measuring and displaying its elongation. The pull of various types of supply chain or conveyor is measured without interrupting operations. The measurement is performed during at least a full conveyor rotation cycle. The element (3) conforms to the shape of the remaining chains links (8). A measurement circuit measures the electrical resistance of strain gauges (5) stuck onto the sides (4) of the measurement elements. The measured valves are transmitted by a telemetry transmitter (7) which moves along with the measurement chain testelement.
Patent DE-3101413-A1 (DE)
IPC: C08J3/12
Filed: 1981-01-17
Abstract: A pulverulent polymer composition which is readily pourable, has a low tendency to form dust and has good stability on storage is composed of a mixture of a vinyl ester polymer and a small proportion of a hydrophobic silica. The composition is prepared by spray drying an aqueous vinyl ester polymer dispersion in the presence of a hydrophobic silica. The silica is preferably a product from the reaction of a hydrophilic silica with an organochlorosilane. The composition can be redispersed in water and the films produced from such dispersions are transparent; they are suitable for the production of paints, glues and adhesives.

Inventor: OBERLAENDER GEORG
IPC: F02B43/08
Filed: 1981-05-14
Abstract: In order to operate internal combustion engines with fuels carbonisable at low temperatures such as peat, wood, brown coal, etc., a gas generator is used. According to the invention this gas generator is enclosed by a pressure shell, which receives a partial flow of compressed air from the intake system of the internal combustion engine.

Title: A disc brake operated hydraulically from one side, with active ventilation of both brake linings
Inventor: LUEPERTZ HANS-HENNING PROF DR
IPC: F16D55/2265

Title: Method for producing a concrete floor-wall structure under water
Inventor: SCHWEIGER BALDUR
IPC: E02D23/00
Filed: 1981-07-03
Abstract: The invention relates to a method for producing a concrete floor-wall structure under water, in which a primary floor made of underwater concrete is laid on the base located below the water level, on which primary floor at least one wall is subsequently erected, as is a complete formwork structure for implementing the method. According to the invention, a sealing frame is embedded into the primary floor, which frame acts as a support and a lower seal for a complete formwork structure which is watertight and the interior of which is pumped out while the structure is standing in the water. Then the wall is dry-concreted in the complete formwork structure, in individual adjoining longitudinal sections if necessary, in the latter case the formwork moving onto the sealing frame and being sealed off in the rear region in each case by the already finished longitudinal section of the wall. The complete formwork structure has a sealing profile on its lower edge, which profile stands up against the sealing frame and ensures that the interior is sealed off. The method has the advantage that the wall can be reinforced and dry-concreted in a way which can be monitored without having to pump out the surrounding water. If two such walls are to be connected to one another by means of a ceiling and, if desired, a secondary floor, the ceiling is mounted between the walls to stabilise the latter by means of pressure before the water is pumped out of the interior. When the water has been pumped out of the interior, the secondary floor can be dry-concreted and connected to the base regions of the two walls.

Title: Method and device for imaging sound fields, in particular ultrasonic fields, with the aid of optical holographic interferometry
Inventor: CROSTACK HORST-ARTUR PROF DR
IPC: G01S15/89
Filed: 1981-11-04
Abstract: The invention is intended, in particular, for testing devices and components for damaged sites, and for monitoring devices and components. It is based on the object of enabling improved detection of material defects and an improved resolution and description of the type of defect. This is achieved according to the invention when a pulse of the sound field to be imaged is illuminated in at least two extreme values at different times by means of a laser beam with a duration which is shorter by comparison with the period of the illuminated sound paths, and in the process the relative phase of the laser parts and of the reference or object beam brought to interfere therewith after illumination is varied between the individual illuminations by a preselectable amount which differs from  pi  and suppresses the optical and/or acoustic noise in the interferogram, as is illustrated in the schematic sketch according to Figure 2. The device according to the invention is characterised by a time delay which initiates the first illuminating process upon the achievement of an extreme value at the start of the sound pulse to be imaged, by the counter, started by this time delay, for counting the half and quarter waves of the sound pulse, which after the achievement of a preselectable odd number initiates a further illuminating process by means of a comparator, a phase shifter, which can be adjusted with respect to the level of the phase jumps, for varying the relative phase between the object beam and reference beam, and a clock generator, which digitises the frequency of the sound signals and controls the phase jumps at the rate of the carrier frequency of the sound signals. <IMAGE>

Title: Method and apparatus for electroplating (zinc-plating) metal strip
Inventor: AVELLONE RICHARD C
IPC: C25D19/00
Filed: 1981-12-14
Abstract: A description is given of a method and an associated apparatus for electroplating one or both sides of a steel workpiece. A row of insoluble (unconsumed) electroplating anodes (206, 206a, 206b; 208, 208b) provided with perforations are disposed at a distance from the workpiece (12). To electroplate only one side, one (206a) or more anodes are preferably disposed above the strip, whereas to electroplate both sides anodes are disposed both above and below the strip. Electroplating solution is pumped through holes in the anodes in order to come into contact with the workpiece for a short time and then drop into a stock container for recirculation. A voltage difference between the anode(s) and the workpiece produces a current flow through the electrolyte solution in order to electroplate the workpiece. Solution collected in the stock container is led to a reaction station and replenished with zinc metal ions. The solution is then pumped back to a main stock container and is fed from that point to the electroplating anodes again. <IMAGE>
