Patent DE-3421172-A1 (DE)
Title: Device for controlling hydraulic drives
Inventor: THIEME GERHARD
IPC: F15B13/01
Filed: 1984-06-07
Abstract: Hydraulic drives for working cylinders of hydraulic excavators which work both in excavating operation and in lifting-gear operation have a lowering-brake stop valve (5) which combines a spring-loaded stop valve (5.1, 5.2) as a non-return valve and a flow-control valve with a control piston (5.3), which can be acted upon by an internal control pressure on the side remote from the stop valve (5.1), in such a way that the control piston (5.3) can open the stop valve (5.1) against the spring loading. To be able to render the lowering-brake stop valve (5) inoperative, a releasable non-return valve (4) is arranged in the bypass. A reversing valve (10) directs an external control pressure (x) to the opening piston (4.2) of the non-return valve (4). <IMAGE>

Title: Drum chopper with waste separation
Inventor: SUENDERMANN KONRAD
IPC: B27L11/02
Filed: 1984-06-19
Abstract: The invention relates to a comminution device, in particular for chopping complete trees, tree crowns and felling remnants. The separation of waste materials during the comminution operation is to be improved by an air flow coming into effect against the flight direction of the separated wood particles in order to sift the flow of material. According to the invention this is achieved by the configuration of the drum chopper similar to the type of construction of a radial fan. The air passes from the end faces of the chopping drum into an axially arranged air-feed duct and flows via connecting ducts through the chip pockets in an approximately radial direction to the outside. The air flow is regulated by further devices.

Title: Mobile (movable) baking oven insert
IPC: F24C15/16
Filed: 1984-06-25
Abstract: For better utilisation and easier cleaning of gas and electric cookers with baking ovens, instead of the previously conventional baking-oven flaps or the fixed inserts, a movable insert is used, which can be used directly for transporting and serving the baked or grilled articles. As a result of the possible omission of holding devices in the interior of the baking oven and with the insert removed, easier cleaning than in conventional baking ovens is also possible.
Patent DE-3427151-A1 (DE)
Title: Application of pure oxygen in practical spray cans as a luxury and utility product
Inventor: TSVETCOVICZ VELIMIR
IPC: A62B7/00
Filed: 1984-07-24
Abstract: The application of pure oxygen in spray cans represents a long overdue innovation in the market for luxury and utility products. The article is environment-friendly, since no additives are used for filling the spray cans. Application as a luxury product: The spray/inhaler can will certainly find many adherents as an environment-friendly alternative to smoking. Application as a utility product: Anyone whose movements have caused him to spend an extended period in a traffic jam or in smog will always carry an oxygen spray can with him as a precaution. A good many traffic accidents have occurred simply because the thinking capacity of the driver or his attentiveness have been lowered as a result of oxygen deficiency and he has been concentrating only on endeavouring to escape from the oppressive traffic jam. Although exhaust gas volumes are soon to be dramatically lowered by law, the OXYGEN SPRAY CAN will render valuable service to the driver for years to come in slow-moving and stationary traffic. The same applies to residential and commercial premises, when exhaust gases outside do not permit the opening of the windows, and the interior air has to be enriched with oxygen.

Title: Process and apparatus for continuous extraction of solid substances by compressed gases
Inventor: SCHULMEYR JOSEF DIPL ING
IPC: C12C3/10
Filed: 1985-03-07
Abstract: By means of a pellet press built onto a high-pressure autoclave, solids can be continuously pressed into an autoclave under pressure. Compressed (sub- or supercritical) inert gas is pumped in counter-current through the bed and becomes loaded with the extractable constituents. By reduction of pressure, the solvent is freed from dissolved substances in a second vessel and, after compression, can be returned to the vessel. The extracted residue is essentially continuously withdrawn at the bottom of the vessel, for example via a ball valve cock, the ball of which is closed on one side.
