Title: Differential pressure transducer and indicator - has curved tube with ball bearing as actuator and indicator element rolling inside tube
Inventor: SCHMITT GEB OETINGER ELFRIEDE
IPC: G01L7/00
Filed: 1977-05-27
Abstract: The transducer comprises an inclined, slightly curved tube (2) with a high-pressure inlet at the lower end and a low-pressure inlet at the top end. Inside the tube is placed a ball bearing (1) which is slightly smaller than the inside dia. of the tube to reduce friction. The tube can be transparent and fitted with a scale to indicate the pressure difference. Alternatively, the ball may be permanently magnetised in order to operate proximity switches. Instead of the circular tube, one with a square cross-section may be used. This has an internal channel in which the ball is guided. Friction is further reduced by this design. To provide a wider measuring range, the channel may be given an inlet jet and a steadily increasing cross-section towards the free end or output. To measure positive and negative pressures, a tube which is turned up at both ends is used.

Title: Bending thermoplastics members esp. for window frames - using rubber guide strips to provide continuous smooth curved surface
Inventor: HEINRICH KLAUS DIPL ING
IPC: B29C53/08
Filed: 1977-09-02
Abstract: A device for uniformly bending thermoplastics members having a continuous, uniform complicated cross-section, such as a window frame member of the like consists of support strips along which the member slides and weights to apply the necessary force, heat being used during bending. The support strips are composed of flush-faced sections of heat-resistant material such as rubber. They possess low flexibility and can thus accommodate to the necessary curve of bending. More specifically the support strips may be supported by a skeleton framwork. A continuous curved surface is obtd. as a result of using flexible rubber, as compared with a polygonal surface which resulted from the previous method of using a series of sections end to end of rigid material.

Inventor: BUCKENAUER GUENTER
IPC: E01D19/06
Filed: 1977-10-15
Abstract: In the device for spanning expansion joint gaps in bridges, or other structures on roadways there are lamellae aligned transversely to the traffic route.

Title: Agitator rotor with adjacent blades of opposite curvature - esp. producing uniform radial component of velocity
Inventor: KIMMEL HANS
IPC: B01F7/00
Filed: 1978-01-26
Abstract: A rotor assembly for an agitator or mixer comprises >=1 pairs of blades curved to a sickle-shape in their plane of rotation. Adjacent blades have opposite curvature, as measured using the centre of rotation as the starting point. Where there is only one pair of blades, the centres of gravity of the individual blades are diametrally opposite to one another. Pref. the curvature of the blade at the impact face is such that the radial component of the velocity imparted to the material on impact with the blade is the same at all points of the impact surface. A high degree of turbulence is produced, resulting in a shearing action between adjacent flows of the mixed material.

Title: Selective extn. of aminoacid hydrogen sulphate salts - with soln. of partially neutralised cumene sulphonic acid in ketone
Inventor: ELLENBERGER WILLI
Filed: 1978-05-26
Abstract: Selective extn. of aq. amino acids (AA) into an organic phase is effected by reacting an aq. soln. of HSO4- salts of AA with a soln. of cumene sulphonic acid (CSA), partially neutralised with alkali, dissolved in a 4-8C nonaromatic ketone. Used for treating H2SO4-hydrolyzed proteins. the system contains no physiologically unacceptable components; is not corrosive to Mo-contg. Cr-Ni steels and improves selectivity and space-time yields. Use of ketones rather than alkanols minimises formation of soap-like gels and facilitates phase sepn. the NH3 salt of CSA is easily soluble in the ketones so AA canbe pptd., by neutralising the extract with NH3, free of impurities.

Title: Crash protection for rear of lorry - has frame mounted on servo supports to control height over road
Inventor: LUETZE HANS DIPL ING
IPC: B60R19/56
Filed: 1978-10-06
Abstract: The crash protection for the rear of the lorry has a frame (4) held under the rear of the chassis on height adjusting supports (1) and operated by servo rams (5). Height sensors (11, 12) on the suspension provide correction signals for the servos so that the frame is hald at a constant height above the ground for maximum protection for following vehicles. The height sensors operate in conjunction with deflection sensors to determine the amplitude of the suspension on rough roads. The frame is lifted to maximum height during reversing.

Title: Winding jig for stator coils of electric motors - prevents bending, abrasion and electric stress on wire insulation and damage by spark-over
Inventor: HAUPT RUDOLF
IPC: H02K15/095
Filed: 1978-11-13
Abstract: The tool accessory is for more efficiently winding a stator pole lamination package (1) through use of insulating sleeves (15) fitted over part of the support arms (6, 5) which in turn are secured to the tool support (9) constituting part of a fixture (4). The insulating sleeves are movable on the support arms and pressed by spring pressure against a stop thereby defining its relative position. The outer edges of the rectangular insulating parts are rounded off to increase the bending radius of the inner winding layers. The sleeve-like parts may open up at one end to facilitate the withdrawal of the support arms on completion of the winding job. This jig also prevents damage to the wire insulation on account of spark-over breakdown between the coil windings and the stator housing when coil wires are electrically heated to fuse the enamel coating.

Title: Composite mine lining mats connection - involves intervening link with plug holes and counterpieces for protruding bar ends
Inventor: WEYAND KARL
IPC: E21D11/15
Filed: 1978-11-18
Abstract: Bars running lengthways and crossways are welded together to make up the composite mat used in underground mining. In one direction, at least, these bars protrude, with the end parts in the form of key elements shaped by cross-sectional variations. These are notched inwards, in a connecting element provided between two adjacent mats, and this has plug in openings on opposite sides, as counterpieces for the key elements. The bar ends may have thickened head configurations. This design gives better results than direct connection between mats, being more easily manipulated in difficult conditions and preventing sagging.

Title: Maintaining constant output from gas laser - by holding buffer-gas pressure constant using permeable wall and controlling pressure in buffer-gas reservoir
Inventor: REYNOLDS THOMAS B
IPC: H01S3/134
Filed: 1979-02-06
Abstract: The gas laser has the pressure of the buffer gas inside its evacuated tube continuously held at a constant value. This continuous control is achieved by using a permeable wall between the tube and a reservoir containing the buffer gas. The pressure in the tube and in the reservoir and the physical properties of the wall determine the rate at which the gas penetrates into the tube. The reservoir's pressure may be increased by heating the reservoir using a coil whose current is controlled by a detector measuring the pressure in the tube. Alternatively, the wall's physical properties properties may be controlled directly.
