Title: Protective coating for steel or other - corrosion prone material containers
Inventor: WERNER NOLL DR
IPC: B65D25/34
Filed: 1969-06-04
Abstract: The steel surface is covered with a corrosion inhibiting glue and open-pored foam material is then stuck over all. This foam is then treated with either a fluid or a paste and later a permanent impervious plastic or other covering. The space between the steel and the plastic is thus hermetically sealed and is subjected to either electric or electronic evacuation and control.

Title: Pressure di e casting hydraulic power system - with accumulators and intensifyer for casting piston
IPC: B22D17/32
Filed: 1971-05-08
Abstract: The casting piston in the casting chamber is powered from a hydraulic cylinder, which is connected in front of the piston with a pressure source and two accumulators, one of which incorporates an intensifyer. In the latter the accumulator piston is mechanically connected with a smaller piston near the main piston chamber at least, when travelling towards the latter. A control chamber is coaxially disposed to the second accumulator, its working space being bounded by two pistons, the one near the main cylinder having a smaller dia. than the accumulator piston. The system does away with the need for a one way valve between accumulator and pressure piston thereby effecting faster power transmission from the accumulator resulting in increased cycle speed of the machine.

Patent DE-2239069-A1 (DE)
Title: Finned heat exchange tubes - have fins shaped and bent up from rectangular tube body
Inventor: KRITZER RICHARD W
IPC: F28F1/12
Filed: 1972-08-08
Abstract: Heat exchanger tubes have fins shaped from the tube body on opposing sides along its axis, the whole forming an integral appts. component. Fins are approximately tongue shaped with their base remaining part of the tube body, from which they are bent up at approximately right angles. Their surfaces facing into the bending direction have a thickened portion below their tips, and are rougher than those opposite, so representing a larger heat exchanging area. These faces are made to front the gaseous medium stream by twisting uniformly along their axis their upper portions and tips w.r.t. their base by up to 90 degrees. A long rectangular block pierced by a series of parallel channels may be used with the fins shaped upon it side by side in line with the channels and sepd. by rectangular grooves, the whole resembling a (double-sided) harrow in external appearance. Working from one tube ends towards the other, such fins are formed one at a time by limited length cuts, first at a relatively steep, then at a shallower angle into the tube body. This operation together with the bending over produces automatically the inner "rougher" surface with its thickened ridge.

Patent DE-2302142-A1 (DE)
Title: Coupled metering pump for filter press - having diaphragm the back pressure on which causes the pump output to vary proportionately
Inventor: STAHLKOPF FRIEDRICH
IPC: B01D37/02
Filed: 1973-01-17
Abstract: Filter aid is metered into a slurry prior to entering a filter press from a metering pump running in tandem with the slurry pump. Both are diaphragm pumps with a secondary fluid behind the diaphragm. The max. pressure is controlled by a relief valve and the stroke is controlled by the flow of secondary fluid. As the pressure in the filter rises, the diaphragm on a flow governor rises and restricts the flow of secondary fluid, thus limiting the pumping diaphragm stroke and reducing the pumping rate. As both pumps operate on the same principle, the flow filter aid reduces pro rata with the slurry flow, giving constant composition.
Patent DE-2312097-A1 (DE)
Title: Rapid injection of thermoplastic foam into moulds - by using explosive pressure
IPC: B29C45/50
Filed: 1973-03-10
Abstract: The outlet of a screw extruder is fitted with a non-return valve, through which the material passes into a chamber where the mould injector nozzle is located in the base. A ram fits down into the top of this chamber, the top end of the ram is connected to a piston in a cylinder. When the dose of material has collected in the chamber, the screw is slowed down and the non-return valve closed. The nozzle is brought to the mould and the nozzle outlet is opened. An explosive charge is ignited in the cylinder above the ram, so that the ram injects the dose rapidly into the mould.
Patent DE-2321673-A1 (DE)
Title: Device for driving conveyor belts - coated with a compsn. contg. a plastics granulate
Inventor: SANDEN JOSEF VON DEN
IPC: B65G39/07
Filed: 1973-04-28
Abstract: A device for driving conveyor belts of rubber or rubberlike materials comprises a drum or belt which is itself coated with rubber or similar material. The coating of the drum is admixed with deformable plastics granulate (e.g. polyurethane, polyolefins,polystyrene) amounting to 2-30% based on vol. of the coating. The granules have dia. 0.1-1 mm. They are embedded in the rubber matrix without being adhesively bonded thereto. When the rubber coating is gradually worn away the granules emerge at the surface and are dislocated and removed from the surface, leaving tiny depressions and "craters" which appreciably increase friction between the driving device and the conveyor belt being driven. Powder transmission is improved.
Patent DE-2331433-A1 (DE)
Title: Haulage chain conveyor drive changeover system - has ramp-actuated auxiliary lever holding drive catch out of engagement
Inventor: KLING GEORG
IPC: B61B10/02
Filed: 1973-06-20
Abstract: The load-carrying crabs travel on a rail by means of front and rear bogies, the distance between which is greater than that between the two drive chains at the changeover point, and at this point the main front driving catch is held out of engagement with the lugs on the second chain by a cam operated by a first ramp on the rail, while a second ramp brings an auxiliary catch into engagement with the lugs on the first cahin. In order to effect crab transfer between chains where the radii of the two rail sections are relatively large or flat in relation to the connecting section, the actuating lever at the rear of the front carb bogie is equipped with an auxiliary lever with pins protruding at both sides, acting against a ramp beneath the rail at the transfer point, and causing retraction of the driving catch where the chain is running round the curve. Coupling between catch and driving lug of second chain thus does not take place unit the crab has reached a point where its rail and that supporting the second chain are parallel.
