Title: Visualisation method for crack patterns - main stress lines are photographed and state of stress evaluated
Inventor: KERENYI GYULA
IPC: G01B11/16
Filed: 1975-01-22
Abstract: A brittle coating with pine and/or synthetic resin as basic material is used. Cracks are produced in it by stressing, and a white indicator paint is used. The surface of the coat is treated with a 10 to 12% aqueous solution of sodium carbonate for 5 to 20 minutes, and then rinsed. It is then treated with a 10 to 12% aqueous solution of sodium hydroxide for 2 to 10 minutes, rinsed and dried. Then a mixture of 2 to 3 pts. wt. of a watery dispersion of a fine grain indicator pigment with grain size of 1 to 20 mu m, and 1 to 2 pts. wt. of titanium dioxide power pigment, is applied on the coat. The surface between cracks can be treated with a watery dispersion of a white matt synthetic resin.

Title: Dough charging machine - with scrapers on endless chain conveyor tiltable between storage hopper and charging funnel
Inventor: PFRANG GUSTAV KARL
IPC: A21C3/00
Filed: 1975-04-16
Abstract: The charging device for a pastry dough moulding machine is an endless chain conveyor with return drums near the charging funnel and over a dough storage container. The endless chain carries a number of transverse flights with cutter blades at an acute angle to the direction of motion. The blades are to dip into the dough surface and carry pinnacle-like teeth at the leading edge; the teeth are offset from one flight to the next by the width of one tooth. This combines a compact design of minimum space requirements with great ease of operation. It ensures a continuous supply of dough for the moulding machine.

Title: Continuous casting tundish - lined with ribbed porous insulating plates for better refining action
Inventor: NEUHAUS HERBERT DR ING
IPC: B22D11/118
Filed: 1975-12-09
Abstract: The tundish is used in continuous casting plant between the steel ladle and the continuous casting mould. The steel is poured into a tray inside the tundish through an immersed tube. The tundish lining includes insulating plates on the bottom, sides and top, made of a silicate fire-brick material with a high pore volume and excellent heat insulation. All lining surfaces in contact with the molten bath are profiled with inclined raised strips. This results in a much more intensive refining of steel which has been killed by silicon and/or aluminium without any necessity of a refining slag layer. The porosity and the profiling of the lining ensure great turbulence and up to 40% of the inclusions are removed in the tundish.

Title: Tubular heating element with tape shaped resistor - has air blown over resistor tape wound along cross shaped former inside tube
Inventor: GLUCKSMAN DOV Z
IPC: H05B3/16
Filed: 1976-03-02

Title: Electrically insulated pipe connection - has O:ring seals in contact with flexibly mounted seal plate
Inventor: WALZ GEORG
IPC: F16L25/03
Filed: 1976-03-16
Abstract: A coaxial pipe connection which is joined by axial clamping bolts or by a radial welding seam, is non-conducting to electricity due to two internal insulating rings (4, 5). The insulating rings are made from rigid material and located between the radial flange (1a) of the inner tube (1) and the two similar flanges of the outer location sleeve (3). Two O-ring seals (10) which are located in axial grooves (1b) of the inner tube flange (1a) are in contact with a metal seal ring (9). The seal ring is bonded to a flexible mounting ring (8). The axial compression of the flexible mounting ring ensures that the tube joint is leakproof yet flexible at the same time.

The suspension can be used in the mass prodn. of machine parts. The life of the mould is increased due to the H3PO4 deriv. acting as a buffer despite the vaporisation of HCl in the reactions taking plate with the impurities in the charge. The mechanical and physical properties of the mould are improved due to the strong adhesion of the phosphates to the particles in the charge and to the reaction of the H3PO4 deriv with the amorphous, silica present in the alkyl silicate binder. The suspension has a viscosity which increases slowly (1-2 s/h for continuous stirring). Uniform coatings are obtd.

Title: Pipeline shut:off stop, esp. for foodstuffs industry - has leakage cavity preventing pressure build up rinsed continuously
Inventor: MIETH HANS OTTO DIPL ING
IPC: F16K25/02
Filed: 1976-05-25
Abstract: In parent patent, a shut-off stop for a pipe line, esp. applicable in the foodstuffs industry, is arranged as a double valve with leakage control. The stop has two valve dishes movable relatively to each other, and during the opening process, after one valve has lifted a little way from its seat, it comes into contact with the other valve, and as the lift continues opens this valve also. The design of the valves create a leakage cavity between them both in the closed and in the open position, which is connected to the atmosphere by control and waste bores, so that the leakage zone is flushed out continuously. In this addn., the valve spindle is bored through and connected by cross drillings to a leakage storage cavity between the valve spindle and the upper valve steam. This modification makes it possible to feed the cleaning water into the storage cavity and from there through the leakage chamber and away to atmosphere, in a simple and efficient manner either from above or from below.

A pigment may be added to material (b); and at least two aggregates (a) of different colours may be used. Different colours can be obtd., giving artistic effects. The hard coating prevents water being driven into capillaries in the clay during pumping of the concrete mixt. being transferred e.g. from a mixer lorry to a site.
