Patent DE-2659276-A1 (DE)
Title: Strap clamp for seat-belt with automatic retractor - has resilient V-shaped body with enlarged leg ends to retain holding ring in position
Inventor: MEYER ERNST
IPC: B60R22/19
Filed: 1976-12-29
Abstract: The webbing (A) is fitted with a clamp (K) made of an elastic material. In its original condition, the clamp has a V - shape with turned-over leg ends. One of the webbing edges fits into the apex of the V- shape and by pressing together the two legs (B) and slipping on ring (E) the clamp is held in position. The grip of the clamp on the webbing is positive enough to prevent the retractor mechanism from an undesirable tightening of the belt, but still allowing additional adjustment by hand.

Title: Flue gases purification process - separates impurities by hot gas drying between scrubber and heat exchanger
Inventor: TAUBERT GUENTER DIPL ING
IPC: B01D53/34
Filed: 1977-01-29
Abstract: Flue gases from furnaces which have to be heated in heat exchangers after leaving a scrubber are first dried by admitting hot gases. The dried impurities are then separated before the flue gases enter the heat exchanger. This prevents the severe corrosive attack of the heat exchangers and increases the service life of them considerably.

Title: Corrosion resistant exhaust gas systems for motor vehicles - where silencer and exhaust pipe are coated with baked vitreous enamel to prevent corrosion
Inventor: HEIDTMANN ERICH
IPC: C23D5/02
Filed: 1978-05-03
Abstract: The silencer is made in a conventional manner from a casing which is subsequently welded to an end plate contg. a pipe which will be joined to the exhaust pipe. Another end plate is used to close the silencer after it has been filled with sound absorbing material. Before assembly of the individual components employed to make the silencer, they are cleaned and descaled and then partly or completely immersed in an enamel slurry, followed by baking to obtain a vitreous enamel coating internally and/or locally, and externally if required. The exhaust pipe can be filled with the slurry and then drained before baking to obtain an internal coating. During enamell ling, zones which are employed for subsequent welding are kept free from enamel, e.g. by masking.

Title: Gas tightness tester for plastics vessel - uses expanding vessel to move slide valve and register threshold pressure
Inventor: GAUCHEL MANFRED ING GRAD
IPC: G01M3/36
Filed: 1978-08-31
Abstract: The assembly tests the gas-tightness of plastic vessels (2). The pressure supply top (5) is lowered on to the vessel and air (7) is pumped in to it until the side of the expanding vessel moves the valve stem (6). The valve then cuts off the air supply. If the pressure drops during the recommended test period, the vessel contracts, the valve is released and the failure signal is given. Alternatively, a second lead through the supply top is connected to a pressure membrane which moves the valve stem as before.
Patent DE-2843202-A1 (DE)
Title: Turbocharger for IC engine - has perforated plate between inlet volute and turbine wheel for better low speed performance
Inventor: BRANSCHEID WERNER
IPC: F02C6/12
Filed: 1978-10-04
Abstract: A tturbine driven by the engine exhaust gases drives a centrifugal compressor which supercharges the intake to the engine. The gases flow radially into the turbine from a volute surrounding the impeller. There is an annular ring between the volute and the impeller. It has openings spaced round its circumference through which the gases flow. The openings are shaped as nozzles and inclined to the tangent to the circumference. At low engine speeds the plate restricts flow and converts the impulsive discharge of the engine into a steady flow onto the turbine blades. This gives effective supercharging at low speeds.
Patent DE-2845468-A1 (DE)
Title: Oil stabilising tube for dipstick measurement during operation - projects into trough in gearbox floor for protection against dynamic pressure
Inventor: LEIMANN DIRK-OLAF ING GRAD
IPC: G01F23/04
Filed: 1978-10-19
Abstract: An oil stabilising chamber enables the oil level in a gearbox or similar unit to be measured whilst the unit is operating using a dipstick despite oil frothing, spraying, wave formation, circulation etc. The dipstick is protected from oil disturbances by a tube with its lower end immersed in the oil bath and with an upper breather. The lower end projects into a trough in the floor of the gearbox to protect it from dynamic pressure arising from changing flow characteristics. A measurement lag is achieved by a narrowing of the tube at a point below the end of the dipstick. If the position of the gearbox prevents easy removal of the dipstick a flexible stick, e.g. a link chain, may be used.

Patent DE-2849136-A1 (DE)
Inventor: SCHILLING KLAUS
IPC: E04B1/32
Filed: 1978-11-13
Abstract: In the case of the lightweight-construction hall, not only are any loads occurring, be they caused by the pressure of snow and/or by wind forces, absorbed by the actual load-bearing structure, but also the roofing skin serves, owing to a corresponding combination with the load-bearing structure, as a load-bearing element. The lightweight-construction hall (1) is provided with an arcuate load-bearing structure (3) comprising individual load-bearing-structure portions (4). These load-bearing-structure portions (4) are made up of individual load-bearing elements (5). The hall (1) comprises a base frame (7). A single load-bearing-structure portion (4) is provided at each end of the hall (1), whereas the other load-bearing-structure portions (4) are combined in pairs and connected at the gable by an articulation connection. Said pairs of load-bearing-structure portions have purlins (9) which can be braced and are arranged in the region of entrances (10) to the hall (1). Otherwise, there are no connections in the form of purlins and the like between the load-bearing-structure portions or the pairs of load-bearing-structure portions. The two end-side load-bearing-structure portions (4) are supported in the base frame (7) by means of supports (12). A roofing (13) is drawn over said arcuate load-bearing structure and is inherently capable of resisting tension such that it can transfer large forces, such as snow loads, without difficulty onto the arcuate load-bearing structure (3). <IMAGE>
