Title: Liquid cooling control in dry tower cooler - using cooled liquid recirculation and liquid injection between cooling elements
Inventor: MORANNE JEAN-PIERRE
IPC: F01K9/00
Filed: 1977-09-27
Abstract: A dry tower with a series of cooling elements pref. finned tubed bundles is used to cool a hot fluid to a required temp. To prevent the cooled fluid dropping below a certain critical temp. an adjustable supplementary amount of fluid can be passed through some or all of the elements. A supplementary flow through all of the cooling elements is obtd. by putting in a recirculation, complete with pump and valve for control and recycling some of the cooled fluid to the hot fluid header at the inlet to the elements. With several cooling elements in series the flow through some of them is increased by injecting some of the hot fluid at the inlet to some of the elements in the series. The hot fluid for injection is taken off from the inlet line to the first cooling element and is branched into the required elements downstream from the first. A combination of the recycling circuit and the injection circuit both with adjustable flow can be used to provide the supplementary flow. Used in dry cooling towers for liqs. that may change state or begin to crystallise if cooled too much. Towers allow the temp. control of the final cooled liquid.

Title: Metal object fault testing using magnetic generator - involves frequency selective circuit tuning during generator calibration oscillation
Inventor: KALISCH ALFONS
IPC: G01N27/90
Filed: 1977-10-15
Abstract: A method of testing elongated metal materials for faults involves passing the material uniformly through the field of converage of a magnetic or magneto-inductive transducer in which electrical signals occurs according to the sample materials condition. These are demodulated and fed to frequeny selective circuits prior to being displayed. The frequency selective circuits are simple and quick to adjust. The transducer is first oscillated in the plane of material motion and the circuits adjusted for optimum display indication. The oscillation is then halted and the material fed through uniformly.

Title: Polarity optimisation in gas chromatography - by two column sections in series in separate thermostated spaces
IPC: G01N30/60
Filed: 1978-05-29
Abstract: A system for the electronic or electromechanical polarity optimization in gas chromatography uses a mixture chromatographic column which consists of two different phases in column sections of equal length. The two column sections are coupled in series and each section can be brought to a temperature independent of the other and be controlled independently. The chromatographic action of this mixing column can be adjusted over the widest possible range from a pure stationary phase B, simply by choosing suitable temperatures and temperature differentials.

Title: Car radiator repair stand - has pneumatic cylinders for clamping, fixing gasket, expanding tube ends and clipping on water chamber
Inventor: ROETZEL DIETER
IPC: B25H1/06
Filed: 1978-07-03
Abstract: The stand for repairing car radiators which have the water chamber pressed on, has columns (2) on feet (4). The two columns are connected at the top by a cross head (3) carrying sets of pneumatic cylinders for various operations during the repair. When the radiator (13) is clamped between two opposing jaws operated by cylinders (11), piston ends (22) of cylinders (21) come into operation pressing down the top water chamber creating a gap between edge of the water chamber and the folded-over edge of the radiator body. A hook-like tool on a pneumatically operated device draws apart the folded-over edges and the water chamber can be lifted off. As access has been gained to the radiator inside the necessary repairs on the tube connections, such as expanding the tube ends is carried out by a special tool and the water chamber is replaced and the straightened edges folded over by another special tool.

Inventor: HOCKE HORST
IPC: B60R22/405
Filed: 1978-07-06
Abstract: The seat belt retractor blocking mechanism eliminates the functional uncertainties caused by friction between moving parts. The sensor of the retractor is a pendulum-type assembly (14) with its upper ring-shaped part suspended from a collar (8) by a wedge-shaped downward protrusion seated in a corresponding notch of the collar.

Title: Yoghurt beaker sterilisation - by heated mixture of expanded saturated steam and air
Inventor: AMMANN SIEGFRIED ING GRAD
IPC: B65B55/10
Filed: 1978-09-12
Abstract: Containers, esp. yoghurt beakers, are sterilised by mixing steam and air, heating the mixt. and injecting it into the beakers. The pref. conditions involve the use of satd. steam of 138 degrees C and 3.5 bar. Mixing with air causes a pressure release and the mixt. is finally heated to 250 degrees C. This is a simple and low-cost method; it achieves satisfactory pasteurisation and leaves no residue of toxic contaminants. It requires much less capital investment than UV irradiation.
Patent DE-2842014-A1 (DE)
Inventor: TSCHIRKY WALTER
IPC: B23Q35/44
Filed: 1978-09-27
Abstract: The correction attachment serves to correct the lead error on a precision machine tool which has a worm gear mechanism consisting of a lead screw (26) and a lead-screw nut (4) and intended for the axial displacement of a machine element (11). In this arrangement, a sensing device (7) is in contact with an adjustable correction guide bar (1) in order to transmit an error-compensating, additional axial displacement to the machine element (11) via a transversely movable wedge (8). The correction guide bar (1) has an essentially plane sensing surface (2) parallel to its axis (5). The guide bar axis (5) encloses an acute angle with the lead-screw axis (6) and lies in a plane parallel to the lead-screw axis (6). The correction guide bar (1) can be rotated about its axis (5) for the correction setting. This provides a simple means of adjustably compensating for the trend lead error proportional to the thread lead of the lead screw (26). When the correction guide bar is rotated, the sensing surface is moved from a position parallel to the lead-screw axis (6) into a position at an oblique angle to the latter. The sensing device moving on the sensing surface now exerts a stroke movement on the adjusting wedge (8). <IMAGE>

Title: Steel housing for high security risk areas - with welded seams accessible to ultrasonic checks during operation
IPC: F16K27/10
Filed: 1978-11-02
Abstract: Large pipe fittings for high security risk areas, such as gate valve housings for nuclear power stations for pipes of up to 1000mm. dia. are mfd. by hot extrusion of the housing from a steel billet. A through bore is machined and its edges are upset by a three-roller expander so that straight tube ends can be welded on. The welds are thus purely circular and accessible to ultrasonic tests during operation. The mfg. costs are much less than machining a housing out of solid steel.

Title: Pretreating molybdenum and its alloys prior to electroplating - where passive oxide layer is removed by cathodic pickling in mixt. of hydrofluoric and hydrochloric acids
Inventor: BEHRINGER GEORG
IPC: C25D5/38
Filed: 1979-03-01
Abstract: The surface of the Mo workpieces is cathodically pretreated in a strong acid electrolyte (I); and is then provided with an adherent layer of Cu by electroplating, using high current density in a bath (II) with a low Cu content but a high content of cyanide and alkali. If required the Cu can be thickened via a cyanide copper electroplating bath (III). Bath (I) pref. contains large amts. of HF and HCl and is used for cathodic pickling; whereas bath (III) pref. contains 5-8 g/l Cu, and is used at 20-100 A/dm2. esp. 20-50 A/dm2 to obtain a Cu layer 0.2-1 um thick. The Cu layer is pref. increased to 2 mu m thickness in bath (III). The process removes the passive oxide layer on Mo, so adherent electroplated coatings can be deposited, e.g. in the mfr. of electric contacts.

Title: Compression of damp refuse - involves using piston to maintain compression pressure for given period of time to squeeze out excess water
Inventor: MANN GUENTER
IPC: B30B9/04
Filed: 1979-03-31
Abstract: The pressuses a pipe, and includes a piston moving to- and fro. The refuse collected from a swer etc. is moved by a conveyor belt to the compressor. It is compressed and de-watered during a stroke of the piston, and it is simultaneously moved forward. The piston remains in the compression position for an adjustable period of time, before being returned to its upper position. The system ensures that a large quantity of refuse may be collected in a tank of given size, with low wastage of power due to unnecessary transporting of water.
