Title: Manipulator for checking circular and longitudinal seams of bends in nuclear power stations
Inventor: SEIFERT WALDEMAR ING GRAD
IPC: G01N29/265
Filed: 1983-10-15
Abstract: The invention relates to a manipulator for checking circular and longitudinal seams of bends in nuclear power stations, in which two similar checking carriages 13a and 13b can be moved on a semicircular sickle-shaped cantilever 12. The sickle-shaped cantilever 12 is guided, in turn, in a sickle-shaped cantilever guide 11 curved concentrically therewith, and is driven by a pinion 14 of a motor 13. In this arrangement, the sickle-shaped cantilever 12 concentrically embraces a pipe bend 2 to be checked, so that when the basic carriage 4, in which the sickle-shaped cantilever 12 is mounted above the sickle-shaped cantilever guide 11, is stationary, the checking carriage 13a, 13b with the checking systems 14a, 14b can trace an annular weld in one operation. In the checking of the longitudinal seams 1a, 1b, the sickle-shaped cantilever 12 with the checking carriage 13a, 13b situated thereupon is moved out of the starting position by 90 DEG , and in this position they can trace the longitudinal seams 1a and 1b for checking purposes by moving the basic carriage 4 on the guiderails 5, which are curved concentrically with the pipe bend 2. Since it is not necessary to change the checking system when checking is switched from circular to longitudinal seams, staff are protected against unnecessary radiation action. <IMAGE>

IPC: C08G73/20
Filed: 1984-03-29
Abstract: Highly heat-resistant polyimidazole and polyimidazopyrrolone relief structures can be manufactured in a very pure form and with short exposure times by applying radiation-sensitive soluble polymer precursors in the form of a layer or a foil to a substrate, irradiating the layer or foil through negative patterns with actinic light, or electrons, or by guiding a light, electron, ion, or laser beam, removing the non-irradiated layer or foil parts, and optionally subsequently annealing. Thereby reaction products, which are prepared in the presence of carbodiimides, of aromatic and/or heterocyclic tetraamino compounds and either: (a) olefinically unsaturated monocarboxylic acids and dicarboxylic acids, or (b) olefinically unsaturated monocarboxylic acids and aromatic and/or heterocyclic tetracarboxylic acid dianhydrides, or (c) olefinically unsaturated tetracarboxylic acid diesters in the form of addition products of the tetracarboxylic acid dianhydrides and olefinically unsaturated alcohols are used as polymer precursors. The relief structures prepared according to the invention are particularly well suited for use as a resist, surface protection, and because of their high purity, as a durable protective and insulating material in the semiconductor area.

Title: Continuous tunnel furnace for drying varnished articles
Inventor: GLASS WALTER ING GRAD
IPC: F26B25/00
Filed: 1984-08-16
Abstract: The continnuous tunnel furnace (1), which is preferably intended for drying varnished bodies (6) for motor vehicles, is equipped with a temperature measuring device (8). The temperature measuring device consists of a pyrometer which is arranged outside the tunnel and which is directed towards the bodies through an opening in the tunnel wall (2), as well as a light barrier (26) which is actuated by the bodies as they pass through the tunnel and brings about contactless measuring of the body temperature when a predetermined measuring surface (M, D) of a body is situated opposite the pyrometer. In order to ensure that, even in the event of a fault, a pyrometer is always opposite a measuring surface, the temperature measuring device (8) has a number of measuring points (10, 11, 12) arranged one after another in the passing-through direction, the distance (a) between adjacent measuring points (10, 11; 11, 12) in each case being smaller than the length of the smallest measuring surface (M) extending in the direction of movement, and the measuring points which are the furthest removed from one another (10, 12) having a distance (A) between them which is greater than the length of the largest space between two measuring areas (D, M) directly following one another in the direction of movement. <IMAGE>

Title: Pressure control in the working air chamber of an air-pulsed jigging machine
Inventor: WEIFFEN KARL-HEINZ
IPC: G05D16/20
Filed: 1984-12-17
Abstract: If the set value of a control of the pressure in the working air chamber of a jigging machine is made dependent on the operating states of the jigging machine, all the faults of a jigging machine which are caused by an excessively large pulsation movement can be automatically counteracted with a single bypass line between working air chamber and relief chamber, the cross-section of which bypass line is of such a size that the pressure in the working air chamber can become smaller than the overall static pressure in an air chamber. The deviations are detected with suitable signal sensors (4); said deviations trigger a preselectable signal (7 to 10) which is matched to the faults and is connected to the controller (1) as a new control variable. Thus, for example even with reduced charging of material, the jigging machine can continue to be operated safely. Even special processes such as the washing out of the bed, which must take place with reduced pulsation can be carried out easily according to the method or with the device, respectively. <IMAGE>

Title: Bag filter for the separation of dusty products and for the absorption of gaseous pollutants from gases
Inventor: JIPP ROLF DIPL ING
IPC: B01D46/00
Filed: 1984-12-24
Abstract: As a result of the arrangement of dirty gas channels 1 and 2 above and from filter bag cells 9 within the dust chamber 5, in the bag filters of Patent Application P33 09983.9, a uniformly distributed flow of the dirty gas from top to bottom and of the clean gas from bottom to top is achieved in the dust chamber 5, which has advantageous effects on the load, wear and operating life of the filter bags 8. The use of a quick-closing flap 19 controlled by compressed air for cleaning of dust from the filter bags 8 by a tapping and blowing effect likewise contributes to an improvement of the functioning of the bag filter. Moreover, a smaller number of large filter bags 8 having relatively large diameters and bag lengths can be used. The object of the invention is to further achieve, apart from these advantages, a high-efficiency absorption of the gaseous pollutants by hydrated lime with the aid of vortex devices 6 and 7 beneath the dirty gas channels 1 and 2 which impart a turbulent flow advantageous for the absorption to the dirty gas in the dust chamber 5. In addition, bag changing is no longer carried out by a laborious removal of the filter bag cells 9 at the side from the filter housing, but by their removal in the upwards direction with the aid of a raisable collection chamber 10 on the bag plate 4 and of a hinged removal door 23 on the bag filter cover.

Title: Adjustable cyclone separator and method for operating it
Inventor: DEWITZ THOMAS SEAN
IPC: B04C5/103
Filed: 1985-02-21
Abstract: The invention relates to a method and a device for changing the drop in pressure at an operations separator without terminating its operation and without considerably reducing the effectiveness of the separation. A flow of a fluid which has particles suspended in it and whose density is lower than the density of the particles suspended in it is allowed to flow tangentially into an upper component of a generally cylindrical eddy chamber so that particles are separated off by radial outward and downward movement in the direction of a particle outlet arranged on the floor, whilst purified fluid is allowed to flow upwards in the direction of an outlet arranged at the top end. The drop in pressure at the separator is increased or lowered by moving an eddy stabilising device in the direction of the fluid outlet opening, or away from it, without interrupting the flow of the fluid or of the particles in the separator.

Title: Device for determining trend channels
Inventor: BOGEN WOLFGANG
IPC: G06G1/00
Filed: 1985-04-29
Abstract: Using this device based on the principle of the parallelogram, parallel straight trend channel lines can be determined from course variations of effects, currencies and so forth graphically recorded on quotations sheets. The action is based on, on the one hand, that with a parallel shift of the device sides, line distances measured along the quotations axis are retained even though the distances between the lines, measured at right angles to the lines, can be shortened or lengthened by this means, and on the other hand, on the finding that trend channels of fluctuations in quotations also become smaller or larger.
