Patent DE-2416385-A1 (DE)
Title: Switch-over shower/bath fitting - contains three-stage piston, with inlet between two radial outlets
Inventor: KEMKER KARL
IPC: F16K11/056
Filed: 1974-04-04
Abstract: The fitting changes the water supply from a shower to a bath. It contains a piston, loaded by the water pressure, and actuated by traction- or pressure rod against a spring pressure, to seal a valve seat to the bath inlet. When not under pressure, the piston is retracted by the spring. A piston with three stages, is guided sealed within a cylindrical sleeve, having an inlet aperture, positioned between two radial outlet apertures. The opposite active piston surfaces are of the same size, when the piston is in a position to open the outlet towards the bath. When in a position to seal this outlet, the piston surfaces are so dimensioned, that the water pressure load is high enough to overcome the spring load.

Title: Agitation of vessels using air lift pump - having gas bell above recirculation tube to reuse gas for pumping forward
Inventor: MAHIG LASZLO
IPC: B01F33/40
Filed: 1974-05-07
Abstract: Vessel is agitated by means of a gas (esp air) lift pump located in the centre of the vessel; above which is a gas bell which collects the air rising from the inlet pipe and feeds it forward to a second air lift pump which pumps the liquid to the next stage of the process. In the line between the gas bell and the second lift pump, a flow control mechanism is installed. The vessel can be divided into several sections with liquid feeding from one to the next and with the air from one zone being collected and reused to agitate the zone above before finally discharging to atmosphere. Appts. is useful for agitating slurries suspended in liquids. In multistage operations, it avoids the need for differences in level between stages or the need to stagger the mounting of the vessels. Ensures that a uniform slurry is pumped from each stage and allows a single air supply to be used to mix and to pump forward without the excessive energy required when the recycling pump is given enough head to pump forward the whole recycle. In one form, several stages can be included in a single vessel.

Title: Hop drying kiln attachment - with roller linkage and scraper loosening blades to suit square kiln rack sections
Inventor: EBERL MARTIN
IPC: C12C3/02
Filed: 1974-10-31
Abstract: An attachment for a hop drying kiln has above the first rack, on which the green hops are charged, a spider with a vertical driven spindle. The spindle carries two radial arms which are fitted with pusher blades and/or loosening tools to distribute the hops evenly in a uniform layer thickness over the whole rack area.

Title: Ceramic tiles with raised decorative pattern - obtd. by using network of grooves on lower punch in tile press
IPC: B28B13/02
Filed: 1975-05-15
Abstract: Process for mfg. ceramic plates or tiles provides with decoration, using a press die and a lower punch to press a tile blank which is then baked. The novelty is the employment of a lower punch possessing a hollow relief pattern corresp. with the desired decorative pattern, and the hollow pattern is filled with the decorative mass or glaze prior to filling the die with the ceramic and pressing the tile blank. In the pref. press, a punch provided with a grooved pattern is raised so the punch is flush with the top surface of the die while a shuttle box fills the groove with a coloured stone material, porcelain or glaze, and the punch is then lowered to form a die cavity filled by the ceramic tile material. It provides a simple and inexpensive method of mfg. products such as tiles provided with a raised, decorative pattern.
