Title: Mechanically opened filter press - employing chain drive to separate plates individually from plate pack
Inventor: WILMS HANS
IPC: B01D25/172
Filed: 1975-12-10
Abstract: A filter press has plates movably supported by arms extending from either side of each plate on a pair of rails. Two synchronously controllable chain drives are located parallel to and one on either side of the slide rails. Striker plates on the chain drive engage corresp. projections on the arms of each plate and thereby open the plate pack by moving the plates away from one another in succession. The novelty is that the plate projections consist of levers attached to each arm of each plate. The levers are capable of swinging in a vertical direction, and when a plate is sepd. from the other plates its levers come to rest in a horizontal position parallel to the slide rails. When two plates come together, or when the first plate comes up against the end stop during the opening process the lever on the rear plate is swung vertically upwards by an inclined strip on the plate in front, so that the part of the lever which engages the chain striker comes free of the chain striker. The process of opening the filter press for removal of cake is simplified.

Title: Treatment of exhaust gases from titanium separation - using alkaline liquor sprays
Inventor: MAUER JOSEF DIPL ING
IPC: C22B34/12
Filed: 1976-07-12
Abstract: Treatment of gases and vapours evolved during the treatment of Ti contg. materials with H2SO4 is claimed. During those parts of the process in which large amounts of vapours are emitted these are at least partially condensed by passage through a hollow cylinder through which a recycling liquid is circulated. During the complete duration of the operation an alkaline liquid is introduced as a fine spray at several positions into the stream of gases and vapours. This is sepd. off from the process and is at least partially recycled. The feed to each position can be controlled in quantity, concn. and degree of atomisation. The exhaust gas after passage through the cylinder contg. the recirculating liquid enters a residence zone before it enters the chimney. Used with titanium extn. processes. Process ensures complete removal of noxious gases and vapours esp. SO3 and SO2. It gives this at all stages of the acid treatment, combining it with sparing alkali usage and permitting variations in the ratio not only between treatments but also during them.

Title: Wire reinforcing frame for concrete posts and piles - uses discs to support longitudinal wires during welding of cross wires
Inventor: PFENDER GEORG
IPC: B21F27/12
Filed: 1977-05-10
Abstract: The wire reinforcing frames for concrete posts or for construction piles can be made by using two discs which have holes to receive the longitudinal wires. The discs are mounted in a machine and are driven from separate electrical motors running at slightly different speeds. As the discs rotate a wire is wrapped around the outside of the bundle of longitudinal wires by means of a spring loaded bending roller. The intersection of the wrapping wire and the longitudinal wires are then welded. By rotating the one support disc faster than the other a helical twist is imparted to the longitudinal wires.
