Patent DE-2805857-A1 (DE)
Title: Embankment soil sealing - is effected by laminate consisting of two layers of bitumastic cpds. sepd. by bitumen-proof plastics foil
Inventor: KOPS FRIEDRICH DIPL ING
IPC: E02B3/12
Filed: 1978-02-11
Abstract: Soil sealing is effected by placing a plastics foil between two bitumastic protective layers, the foil being compatible with the bitumastic compsn. The process is used for sealing surface layers of embankments or dams used for water reservoirs. Use of plastics sheets reduces costs of construction and sheets which are biaxially oriented are capable of withstanding of up to 100% distension induced by stresses caused by soil subsidence. Sheets can be thermowelded in an integral waterproof unit.

Title: Separator for gas borne dusts - has housing with profiled body forming form annular flow passage with flights to impart radial and tangential motion
Inventor: CONNER WAYNE LAWRENCE
IPC: F02M35/022
Filed: 1978-02-21
Abstract: Separator for gas borne dusts in high velocity gas streams has four zones. IT has a profiled body mounted in a circular housing. This creates a diverging annular passage and gives a radial motion to particles in the gas stream which impinge against the body. Towards the end of the annular passage are a set of flights to impart a tangential motion. The now spiralling stream is accelerated past a converging section into a sharply diverging section where it slows down again. The particles are held along the outer wall by centrifugal action and are extracted while clean gas flows from the centre. For use in internal combustion engines, diesel engines, jet engines, turbines, etc. which need a supply of clean air or other gas. High efficiency and low pressure drop are obtd.

Title: Vehicle guidance system with microprocessor control - uses stored program control for route diversion with command signals passed by inductive loop
Inventor: SCHNAIBEL EBERHARD DIPL ING
IPC: G05D1/02
Filed: 1978-04-04
Abstract: The guidance system consists of a guide cable (10) which joins one location (A) to another (B) along which the vehicle is guided. An inductive loop allows command signals to be passed to the vehicle. The control system in the vehicle operating the steering, brakes, drive etc incorporates a f.o.m. so that a programmed route or diversion may be stored and executed. At a certain point (12) along the guidance cable, the programme is fed in. The vehicle continues forward under the influence of the stored programme. The data is checked at a further point (13) for validity before the vehicle undertakes a diversion and tipping and loading operation (14) before returning to the guidance cable route.

Title: Hygroscopic safety switch has sponge-like material - soaking up condensed water and expanding to operate microswitch via lever to turn off e.g. compressor
Inventor: FRENKEL WALTER
IPC: H01H35/42

Title: Gaseous oxygen prodn. for fluctuating demand - uses liquefied buffer storage for minor fluctuations but has standby compressors for major fluctuations in demand
Inventor: GUETHER HELMAR
IPC: F25J3/04
Filed: 1980-03-28
Abstract: Prodn. gaseous oxygen by low-temp. rectification of air consists of compressing the air, cooling it and feeding it to a rectifier unit from which the oxygen is drawn off as the prod. Fluctuations in the oxygen demand are balanced out by storing excess oxygen in liquid form during low demand periods and evaporating the stored oxygen during high demand periods. During high demand periods, at least one additional compressor is connected in parallel with the original compressor. Each compressor, when under full load, supplies only a portion of the air processed in the rectifier. Pref. different air flows are supplied by the two compressors under full load. More specifically, one compressor supplies approx. 45% and the other 55% of the maximum air quantity that can be processed in the rectifier unit. Used for any industrial or other process where the oxygen demand can fluctuate, in particular for the prodn. of oxygen for effluent purificn., where the demand varies widely according to time of day and season.
