Title: Automatically retractable astragal for double swing door - is moved horizontally by operation of crash bar
Inventor: MEISTERHEIM RICHARD A
IPC: E05B65/10
Filed: 1975-01-27
Abstract: The astragal is operatively interconnected with the panic or emergency exit bar of the door and is automatically retracted if the door is panicked. Suitable motion driving mechanism is provided for driving the astragal between its projected and retracted positions in response to vertical movement of the actuating rod (52), and additionally such motion driving mechanism constrains the actuating rods (52) to move only vertically. One or more driving pins fixed to the actuating bar ride in vertical slots in the astragal housing (42b). In order for the driving pins (54) to get from the actuating rod to the astragal housing the driving pins must pass through the astragal (50) itself, provided for by an angled slot in the astragal.

Title: Quick brewing coffee and tea filter - has centre ram for swirling water to accelerate flavour release
Inventor: SCHMIDT KARL-HEINZ
IPC: A47J31/20
Filed: 1975-11-07
Abstract: The universal coffee and tea filter is made from non-aromatic metal or plastics. It has a filter sieve (1) on a shaft (2) and a filter base (3) with or without a cleaning aperture. The preparation time for coffee and time using this filter is much faster than with conventional methods since the hot water moves round the ground coffee to release the flavour. This process is accelerated by using the ram (5) to swirl the water and ensure that the entire vol. of water comes into contact with the ground coffee. The flavour is kept in the beverage by the lid (4) which keeps back most of the steam. The water and the prepared drink are contained in a canister (6).

Title: Sealing arrangements for rotary piston engines - using several blade strip type seals in series to reduce wear
Inventor: ZOCHEW DANCHO DIPL ING
IPC: F01C1/10
Filed: 1976-01-19
Abstract: The sealing arrangements for rotary piston engines are intended for engines with a smoothly contoured lobed rotor (2) orbiting around a shaft (4) in a casing with one more working chamber (5) than the rotor has lobes. The working chamber profile closely follows that of the lobes, except in a sealing zone between chambers where there are axial seals in continuous contact with the rotor surface. Seal consists of seven strips (6) set in slots perpendicular to the casing surface, backed by corrugated-strip springs (7) which press them against shoulders in the slots. Projecting into the working chamber, these strips in turn seal against the rotor as it orbits; a similar seal arrangement is fitted in the end faces.

Title: Electrolysis furnaces for mfg. light metals e.g. aluminium - using carbon cathode contour which prevents excessive agitation of bath
Inventor: JOB WILFRIED DR ING
IPC: C25C3/08
Filed: 1976-01-30
Abstract: Cathode for electrolysis furnaces used for the winning of light metals is claimed. The novelty is that the height of the carbon bed below the anodes and above the cathode busbars increases from the middle of the furnace towards the edges. In the transverse section of the furnace, i.e. in the longitudinal direction of the busbars, the carbon bed pref. forms a well with its deepest point at the middle of the furnace and blending into the side walls. Alternatively, the carbon bed may form a well in the longitudinal direction of the furnace, i.e. at 90 degrees to the longitudinal direction of the busbars. Another alternative is that the busbars may be nearer the surface of the carbon bed in the middle of the furance than at the two ends. The invention is designed for large, modern electrolysis cells which normally suffer due to excessive stirring of the bath by the high electric currents. The vertical current density is better; the yield of Al per unit of current is improved; and the life of the furnace lining is increased.

Abstract: A rotary filtration plant has a filter (e.g. of drum or disc type) mounted on a shaft which is immersed in the suspension to be filtered in a trough. The shaft bearings are located outside the trough, and the shaft protrudes through openings in the ends of the trough which are slightly larger in dia. than the shaft. The use of seals, which are inevitably troublesome, is eliminated.

IPC: B01D33/00
Filed: 1976-02-23
Abstract: Sepn. of a two-phase mixt. contg. a liq. uses centrifugal force. The mixt. is fed into the space between two permeable endless belts. These are driven at considerable speed around a spiralling pulley system about a vertical axis. The liq. is expelled by the centrifugal action and the prod. finally removed. The belts then return continuously to the start. The belts are flexible and once the feed is enclosed can be inclined. They can be of woven or vlocked metal wire, plastic, rubber and/or canvas. An open-sided sleeve can be used. They can be hydrophobic or hydrophilic or coated with a hydrophobic or hydrophilic material. Used for dewatering slurries, muds or chemical process prods. esp. waste or sewage residues. There are many problems with existing separators, slow, inadequate sepn., bulky, expensive to install and maintain. This system improves on all these features.
