Patent DE-2528298-A1 (DE)
Title: Soap bar with core of expanded polystyrene - capable of floating and allowing complete consumption of soap
Inventor: BUERGER KURT
IPC: C11D17/02
Filed: 1975-06-25
Abstract: Complete consumption of soap is allowed by introducing into a soap bar a core of expanded plystyrene or similar matl. during mfr. of the soap bar, so that the soap bar will float on water, thus preventing it from slipping out of the hands in the bath tub. It is partic. important with the ever increasing scarcity of raw matls. that the soap should be used up completely by the user, and not partially thrown away due to the difficulty of using a small piece of soap. In an example, the soap completely surrounds the polystyrene core, which has approx. the same cross-section as the whole soap bar.

Title: Slit-shaped extrusion die with variable extrusion width - obtd. by liq. cooled slide valve which increases local viscosity
Inventor: PENROD WILLIAM R
IPC: B29C48/08
Filed: 1975-08-01
Abstract: Nozzle regulating device, esp. for varying the width of a slit-shaped nozzle, e.g. for extrusion of thermoplastics sheet consists of a slide valve which can be moved transversely across the outlet slit of the nozzle. The slide valve contains a cooling liq. circuit, and a heat transfer plate or similar device which transmits the cooling effect of the circuit to the flowing material in the obturated part of the nozzle, thus increasing the viscosity of the material. The increased viscosity improves the sealing action at the valve, enabling accurate adjustment of the width of the extruded sheet to be attained. In addn. the hydrostatic press. on the valve is reduced, making sliding easier.

Title: Hydraulic crimping tool making gas-tight seal - in copper capillary tube used to evacuate containers
Inventor: MEYER MANFRED
IPC: B23K20/02
Filed: 1975-10-09
Abstract: Metal pipes are closed so a gas-tight seal is obtd., esp. capillary tubes used to provide a high vacuum in a container. The pipe wall is squeezed so the metal flows to make a crimped joint. The pipe wall is pref. squeezed between two convex jaws with radii of curvature 1.5 mm using a load of 900 t.

Title: Gas or steam turbine system - uses same size parts with varying stage press. drops and changing nozzle with shape to vary conditions
Inventor: HIRSCH PETER
IPC: F01D5/14
Filed: 1976-05-22
Abstract: The gas or steam turbine design uses the same size parts for a variety of stage press. drops and is partic. suitable for small, single-press.-stage turbines. In such a design with a design flow/velocity ratios u/co=u1/co1 for the first or determinant stage, blading dimensions and arrangement for up to 3 rows of velocity-compounded blades need not be changed just because of a change in the design press. drop. What is required is to change the aperture ratio and flaring of the inlet nozzles, to produce the appropriate reaction. Similarly, the same blades can be used with flow/velocity ratios (u/co) varying by up to plus-or-minus 20% from the design figure. For variations in output, blade width only need be changed.

Title: High speed tunnel kiln for baking porcelain - with indirect cooling of the slides carrying the porcelain through the kiln
Inventor: BAUMANN HELMUT
IPC: F27D9/00
Filed: 1976-08-03
Abstract: Tunnel kiln for the high speed baking of workpieces, esp. porcelain, where the workpieces travel through the kin on slides. At least the high temp. zone of the kiln is fitted with a device for the indirect cooling of the longitudinal sides and/or the underside of the slides. The cooling device pref. employs tubes with a rectangular cross-section, where the tubes are laid parallel with the direction of slide travel so >=1 outer wall of the tubes is near the longitudinal sides of the slides; and each tube has an inlet and outlet for air obtd. from the atmos. surrounding the furnace. High speed tunnel kilns are ued for sintering ferrites, and the short cycle time would be very useful for porcelain prods., bu the slides have not been able to withstand the baking temp. of >1400 degrees C. The invention provides local cooling of the slides so porcelain can be baked in high speed kilns.

Title: Steam husking machine for fruit is purged of air - before pressurised steam is introduced thus reducing energy consumption
Inventor: KUNZ PAUL
IPC: A23N7/00
Filed: 1976-09-14
Abstract: A steam husking machine for fruit or the like comprises a rotatably mounted pressure vessel, in which the opening is closed by an externally actuated lid. When closed and sealed, the vessel is filled with a pressurised medium, esp. steam. The vessel contains a supply line for the introdn. of the pressurised medium, arranged in such a way that air already inside the vessel is displaced out of it. By displacing the air from the vessel, the need to raise the temp. and thus also the operating pressure of the steam is eliminated. As a result, a saving of about 40% of hot steam is achieved.
