Patent DE-2262254-A1 (DE)
Title: Foundry sand liquid bonding agent dispenser - consists of adjustable piston travel cylinder
Inventor: MICHEL HORST-WERNER
IPC: B01F15/04
Filed: 1972-12-20
Abstract: The foundry sand bonding agents are dispensed to the sand mixer from a two stroke dispensing unit. The first stroke involves the transfer by suction of each additive soln. from a tank through a pipe into a dispensing cylinder fitted with an adjustable travel piston, which travel can be infinitely varied for the suction stroke. The second stroke controls the injection of the liquid from the cylinder through a feed pipe into the sand mixer. In this stroke the piston travel is limited by a fixed stop. The variable suction stroke travel of the piston may be pref. effected by suitable limitations on the piston rod travel which is attached to alternative pneumatic, hydraulic, electro-magnetic, motorised drives. The system is flexible and eliminates human error.

Title: Pouring asphalt prepn. for building - by high-speed mixing of fillers and binder, followed by slow-speed mixing
Inventor: KOENITZER KARL-HEINZ
IPC: C08L95/00
Filed: 1974-07-04
Abstract: Dried and heated fillers are charged, with over 6 wt.% liquefied binder, into a twin-shaft mixer and intensively mixed at a circumferential speed of the blades of 2-3 m/sec. until converted from solid to liq. state, during which conversion the mixing speed is reduced by up to 50%. The filler is rapidly coated with binder, and incorp. of air into the compsn. during mixing is avoided, so that a final dwell period for de-aeration is unnecessary. Advantages of batch mixing, e.g. for frequent charges in compsn., are retained.

Title: Mechanical coupling with spring loaded crank - has eccentric bores and connecting sleeve operated by an actuator
Inventor: BEUCHE WERNER
IPC: F16D17/00
Filed: 1974-12-18
Abstract: The mechanical coupling between a driven and driving shaft uses crank effect. The coupling elements (2, 4) have conical and eccentric bores (3, 5) which accommodates a helical spring (6) enclosing a sleeve (7). This sleeve (7). This sleeve carries out in the idling position a corresponding swash plate movement in the eccentric bores (3, 5). The driven and driving shaft are coupled by the axial relative displacement of the eccentric and conical bores (3, 5) by means of the spring which produces a crank effect until the coupling elements (6, 7) form a crank. This mechanical coupling is used especially as a connecting and disconnecting clutch whose action depends on the crank effect.
Patent DE-2459857-A1 (DE)
Title: Pneumatic cylinder negative impulse valve - has control plunger positioned to be impacted by piston at cylinder end
Inventor: GOETTLING HELMUT
IPC: F01L25/06
Filed: 1974-12-18
Abstract: The valve is for the automatic reversing of a pneumatic double-acting working cylinder, contg. a valve control plunger. The control plunger is positioned so that with an impact of plungers on the valve ends, and the negative control thus produced, it is alternately reversed, at certain end positions of a predetermined working stroke. This causes the alternate connection of one of two working conduits, to one of two common throttle-able reliefs. The second working conduit is connected to an air supply conduit, for a control working process. Instead of relief apertures, the control chambers have control connections each with a sealing valve. Due to this, a forced ventilation of the control chambers and the control cylinders, via the control connections and the sealing valves, can be prevented.

Title: Ozone generator with two-way valve on outlet - which isolates gas stream and puts water to ejector mixer inlet
Inventor: BERGER BERND
IPC: C01B13/11
Filed: 1975-01-11
Abstract: O3 is produced from dried air in generator having cooling water inlet and outlets, and an injector mixer connected to the gas outlet which mixes the O3 into a circulating water system. A two way valve is installed on the suction line to the injector such that the cooling water outlet is joined up to it. During normal operation, the two way valve allows O3 to pass to the injector and cooling water to run to drain but when switched off, the gas outlet is isolated and the cooling water directed to the injector suction. For use with ozonising systems where the O3 is used to prevent microbiological growth in circulating water systems. When the gas outlet is connected directly to the injector there is a danger that moist air can be drawn into the generator causing short circuiting and damage to the electrodes. The system described prevents this.
