Patent DE-3602425-A1 (DE)
Title: Shut-off valve
Inventor: NEMETZ JOSEF
IPC: F16K1/226
Filed: 1986-01-28
Abstract: In the case of shut-off valves exhibiting a sealing lining which is arranged in the housing and consists of a material with an insufficient restoring force, as is the case, for example, with fluoroplastics, a resilient assisting member is usually assigned to the sealing lining. The known combinations of sealing lining and resilient assisting member have different disadvantages such as restricted operating-temperature limit, no anchorage or insufficient anchorage between sealing lining and assisting member, etc. These disadvantages are eliminated in that the sealing lining, in a compressible, but relatively firm and correspondingly temperature-resistant material, is anchored in a positively locking manner via grooves.

Title: Through-passage connection piece for sanitary fittings
Inventor: LUKE RAINER DIPL ING
IPC: E03C1/02
Filed: 1986-07-26
Abstract: The invention relates to a device for the connection of water mixer units to supply lines for cold and hot water, there being provided in each case a connection piece which is configured in the form of a T, exhibits a through-channel for the connection, on both sides, of a supply line and has a connection stub which projects perpendicularly to the supply lines and is arranged, for the water mixer unit, axially offset with respect to the through-channel to such an extent that the pipes for cold and hot water are at the required mutual spacing. In order to improve said device, the invention proposes that, on the connection piece, there be configured a securing means in the form of a radially projecting extension for the other supply line, with the result that the cold-water line and the hot-water line are positioned at the predetermined spacing from one another.

Patent DE-3634828-A1 (DE)
Title: Changeable storage apparatus
Inventor: PAULS JUERGEN DR
IPC: F24F12/00
Filed: 1986-10-13
Abstract: The changeable storage apparatus serves to recover heat from humid, dust-laden and highly corrosive foul air of building rooms, preferably stables and cow sheds. The aim of the invention is to provide a heat recovery device for the specified applications which has a small specific material requirement, low production and operating costs, is easy to clean and does not freeze up. The disadvantages of known heat recovery devices for the specified field of application are thereby to be avoided. The changeable storage apparatus according to the invention is characterised by a constructional design permitting its assembly from special prefabricated components at the place of use. The central component is a flap box with flap and actuating drive and also with lateral connection openings for the storage devices, as well as with connection pieces which are connected to the incoming- and outgoing-air conduits and to corresponding ventilators for conveying the air currents. The storage devices consist of special storage elements which are stacked one on top of the other.

Title: Double belt unit for a conveying system, in particular for linking a plurality of workstations
Inventor: SCHMID EBERHARD
IPC: B65G17/00
Filed: 1986-10-15
Abstract: The invention relates to a conveying system having a so-called double belt unit, in particular for linking a plurality of workstations, two conveyor belts, which run parallel in one direction, together moving a workpiece carrier. The two conveyor belts are both endlessly circulating, flexible belts. They are deflected, at the beginning and end of a conveying section, via rollers, and the rollers at the destination end of the conveying section are driven in such a manner that the upper belt, which bears the workpiece carriers, is drawn there over this driven roller. At the same time, according to the invention, all of the rollers are mounted by means of their bearings, in a cantilevered fashion in each case in one outer wall. The driven rollers are preferably indirectly driven. The concept according to the invention permits a cost reduction and a substantially greater flexibility of such a transport system. It is easy to install and also provides more free space for the conveyed items.

Filed: 1986-10-28
Abstract: The invention relates to a piece of sectional furniture, in particular office furniture, of which the basic components for a supporting framework (13) are cross-sectionally rectangular, preferably square, elongated beams or supports of the same width. Through-holes are provided at the end regions of the beams, two holes on one broad side and a third hole offset by 90@. Two respective beams enclose with their end regions two further beams, so that extendable corner junction points (14, 15) result, in which the beams can be screwed against one another by means of screws (7). This produces a stable, variably extendable supporting framework, which can be supplemented by tabletops, shelves, drawers and the like, as the basic unit for a piece of sectional furniture. <IMAGE>

Title: Protection against low sun
Inventor: GRUNEWALD JUERGEN
IPC: B60J3/02
Filed: 1986-11-25
Abstract: The protection against low sun disclosed here consists, as is the case with sunglasses of unbreakable glass or unbreakable plastic, or similar material, which corresponds to current safety requirements and is either attached to the sun visor or installed in the sun visor. In the installed state, it is pulled out as required whilst the attached protection against low sun is folded down as required. The attached protection against low sun is also suitable, by virtue of the ease with which it is mounted, for retrofitting in already existing vehicles. The protection against low sun ensures that when the sun is low the driver can see through the protection against low sun and therefore the risk to traffic is very greatly reduced.

Patent DE-3719748-A1 (DE)
Title: Antilock device for the brake system of a motor vehicle
Inventor: BINNEWIES LUDWIG
IPC: B60T8/70
Filed: 1987-06-12
Abstract: In conventional antilock devices, the brake slip between wheel and underlying surface is detected in order to determine whether locking is occurring. For this purpose, the wheel speeds are measured by means of speed-of-revolution signal transmitters (3, 4, 5, 6). However, since the wheel speed during the braking process is generally smaller than the speed of the vehicle, an errored brake slip value is obtained. In order to avoid this error, with the antilock device according to the invention the speed of the vehicle is detected by means of an acceleration signal transmitter (2). When cornering, the speed difference between outside wheels and inside wheels is taken into account by means of a steering-lock signal transmitter (7) and a correction unit (13). <IMAGE>

Patent DE-3800863-A1 (DE)
Inventor: KARBACH ALFRED DR
IPC: F22B31/00
Filed: 1988-01-14
Abstract: The production of water vapor is controlled in a plant for combusting fine-grained and dustlike solid fuels together with air in a combustion zone of a heat exchanger in the upper region of the combustion zone, a water vapor accumulator, which communicates with the heat exchanger, and a water vapor feed line leading from the water vapor accumulator to a turbine. The rate at which water vapor is produced is continually calculated and is compared with the desired value which is required by the turbine and the rates at which fuel and combustion air are supplied to the combustion zone are adjusted in accordance therewith. The combustion plant may comprise a fluidized bed cooler for cooling a part of the part of the combustion residue. That cooler may comprise a plurality of chambers provided with heat exchangers for an evaporation of feed water or for a super heating of water vapor. Any water vapor which is produced from feed water in said chambers will also be taken into account in the calculation of the total rate at which water vapor is produced in the combustion plant.

Title: Process for purifying the exhaust air of vulcanising plants
Inventor: LADWEIN BERNHARD
IPC: B01D53/00
Filed: 1988-04-19
Abstract: The exhaust of vulcanising plants is purified by complex processes which still result in an unsatisfactory purification. The novel process is intended to enable the exhaust air of such plants to be released clean into the atmosphere with a justifiable expenditure. The invention comprises cooling the hot exhaust air stream in an absorber constructed as a multichamber scrubber by spraying with cold water so intensively that the oily water-insoluble pollutants condense, arise as concentrates in the treatment of the pollutant-laden scrubbing water of the water circulation, are taken off and are disposed of by combustion. As an essential resulting advantage, a process is available by which the exhaust air of vulcanising plants can be freed from pollutants inexpensively and no pollution of waters occurs. The process is applicable to vulcanising plants of all types.
