Patent DE-3201910-A1 (DE)
Title: Flexible overpressure valve for pneumatically stressed bodies
Inventor: SCHULZE BERND
IPC: A62B1/22
Filed: 1982-01-22
Abstract: The invention can be used for all pneumatically stressed bodies which are operated in the low-pressure region. Use in the case of jumping cushions for rescue purposes is particularly advantageous. The aim and object of the invention are to create a device which dissipates any overpressure which occurs rapidly and safely, subsequently closes itself again automatically, and does not adversely affect packaging of the pneumatic body in a very small space. The solution according to the invention provides for the fitment of connecting pieces to jacket openings which are closed by elastic strips. When an overpressure occurs, the surface pressure on the connecting pieces affects the tension force of the strips, as a result of which the complete openings are released. Once the pressure has reduced, the original position of the connecting pieces is set again automatically. <IMAGE>
Patent DE-3206827-A1 (DE)
Title: Fire extinguishing bomb
Inventor: MODAK MALAY DIPL ING
IPC: A62C19/00
Filed: 1982-03-30
Abstract: Each year, thousands of hectares of forests are destroyed by fires. The sites of the fires are difficult, if not impossible, to approach with heavy firefighting gear. Nor is it possible to bring the fire under control by dropping water from aeroplanes. These problems have prompted me to try and design a "fire extinguishing bomb". Said "bomb" is a perspex sphere which, on its outer surface, is provided with "brake rods". Said rods contribute to a reduction in the dropping impact and to the prevention of "rolling down" on the mountain slopes or at the suitable sites. One row of said rods is located on each of the two upper parts of the two sphere halves. The third row of rods is located along the meridian of the sphere. The rods of the two upper parts of the sphere are shorter than the rods along the meridian. Furthermore, the rods on the upper parts of the two sphere halves point upwards. On the free ends of the rods, small platelet-like structures are disposed, in order to prevent "rolling down" and to allow the sphere to get caught on the plants or bushes while "rolling down". The fires occur both on the ground and above ground (on the trees). Therefore, an "extinguishing agent" would have to be found which is suitable to be used for both of these objectives. In my view, a mixture of CO2 and N2 is the most suitable agent. As is known from chemistry, N2 (nitrogen) is almost as heavy as air. Therefore N2, like air, floats above the ground. CO2 (carbon dioxide), in contrast, is heavier than air and remains lying on the ground.

Title: Press part for waste materials
Inventor: ALBERS WILHELM
IPC: B65F3/20
Filed: 1982-04-01
Abstract: A press part for waste materials, especially for filling a self-pressing container with refuse, contains a press piston which is mounted displaceably to and fro in front of an ejection orifice for the waste materials, between a retracted position defining a filling region in front of its end face and an advanced position, in which its end face reaches at least up to the ejection orifice, above a surface forming the bottom of the filling region. It contains, in its rear region, a plurality of cover segments which, as a filling-space covering, cover at least the region which is located behind the press piston and through which the latter travels. The cover segments are connected to one another in an articulated manner so as to adjoin one another without a gap and are positively displaceable in the manner of a blind along a predetermined guide track, in such a way that they swing out upwards or downwards during the return of the press piston out of its advanced position.

Title: Jacquard flat-bed knitting machine
Inventor: BEYER GUNTER
IPC: D04B15/70
Filed: 1982-04-16
Abstract: The invention concerns a jacquard flat-bed knitting machine with needles which are arranged in the grooves of the needle bed and which are each assigned a needle selector which is slidable in the direction of the needle clearing position and transversely pivotable thereto, and has for its purpose to increase the knitting speed by guiding the butts of the needles which are not knitting the pattern out of their cam track. This is achieved according to the invention when the shank of each needle is, below the loop-forming butt, freely slidable in the direction of the needle clearing position along a first abutment formed at the upper end of the needle selector and acting in the pivoting direction, and guided essentially free of play at right angles thereto, and the butts of the needles which according to the pattern are not intended for clearing are, by means of a first pressure strip acting on the associated needle selector, guidable out of their cam track and lowerable into the needle bed and, by means of a control device acting in the region of the selection point in the direction opposite to the pressure strip, translatable back into their cam track. <IMAGE

Title: Method for reducing the ageing of lubricating oil in internal combustion engines
Inventor: HECHLER HANS DIPL KFM
IPC: F01M1/12
Filed: 1982-07-07
Abstract: In the method according to the invention for reducing the ageing of lubricating oil in internal combustion engines and thereby prolonging the useful life of the lubricating oil a gas layer, which is composed of a gas free of free oxygen or any other substance having a negative effect on the lubricating oil quality constantly flows through the lubricating oil stored in the oil sump and/or in the case of dry sump lubrication in the separate lubricating oil tank. This ensures that harmful extraneous substances such as water vapour, fuel mixture residues etc. are expelled. Among other things, it is also possible to use, inter alia, the exhaust gas of the internal combustion engine as the shield gas layer.

Abstract: An apparatus for the alignment and/or level adjustment of subsurface structural members, in particular for adaptation of covers to a certain level with simultaneous alignment with a surface, has formwork parts, which can be clamped together, for defining a space developing between structural members to be arranged one on top of the other. The formwork parts (1, 2) are provided with clamping means (26, 30) for firmly clamping to the structural members, feed openings for a rapidly hardening grouting compound, and supporting devices to which top attachable structural members can be adjustably anchored. When a rapidly setting mortar is used, the formwork can be dismantled and re-used, the structural members attachable at the top being secured. Use as permanent formwork in a releasable arrangement of the auxiliary devices is also provided. This requires feed hoppers arranged on the outside at openings in strip-shaped formwork parts. <IMAGE>
