Patent DE-2952169-A1 (DE)
Inventor: JANDA WENZEL
IPC: C02F1/04
Filed: 1979-12-22
Abstract: During evaporation for the production of soft water from raw salt water or briny water, by using uptake tubes heated from outside, the inner walls of the tubes are covered with a substantial amount of sediments. The elimination of such a layer of sediments takes place generally by stopping the evaporator and by mechanically cleaning the different tubes. It is also known to scrape the deposits during operation of the evaporator, which leads to the destruction of the tubes. Further, the cross section area for the passage of fluid is substantially narrowed. According to the invention, it is proposed to actuate, in all the tubes (4) during operation of the evaporator, spiral springs (22) which extend along the tubes; these springs have a negligible influence on the tube walls and eliminate the sediments by means of the turbulence generated.

Title: Control of gas flow to consumer - employs regulators and valves in module located below ground level, and maintains supply at given pressure
Inventor: STOVES DEREK
IPC: F17D1/04
Filed: 1980-01-03
Abstract: The pressure and/or flow of gas are regulated so that the flow to a consumer is maintained at a given pressure. Reduced size of a regulating installation allows it to be located below ground level thus obviating requirements for construction of a cabin. A regulator module (10) is isolated by valves (13, 14) and comprises a lower envelope (21) to which the inlet (52) is connected. The gas enters a chamber (24) at high pressure to pass through a filter (2) to a central chamber (25) to which the outlet (33) is connected. In this chamber, the gas flows through control (3) and active (4) regulators and also a rapid shut-off valve (5). An upper chamber (26) contains two servo controllers (7, 8) which control the regulators. A control (43) operates the shut-off valve.
Patent DE-3002452-A1 (DE)
Title: Wooden table or work top with plastics edging - has shaped cut edge faces to cause shrinkage setting of plastics withstanding stresses
Inventor: MEIER MAX
IPC: A47B13/08
Filed: 1980-01-24
Abstract: The cut faces (9) of the wooden table top are sealed round the edges by a plastics edging strip wherein directly adjoining the upper edge (11) the cut face (8) is drawn in to form a rear cut section (9) after which it then protrudes out again. Through this rear cut section and adjoining projection a build-up of material is obtained in the area of the cut face which when the plastics hardens shrinks more severely than the remaining area of the edging. Since the edging extends round the entire plate a strong tensile force arises in the direction of the cut faces owing to the shrinking forces. The edging is thus strongly biased so that even after long usage the edging does not become loose.
Patent DE-3009294-A1 (DE)
Title: Needle shaped boss prodn. on workpiece - involves progressive single pass grinding operation with axial motion
Inventor: DIENER HERBERT ING GRAD
IPC: B24B5/14
Filed: 1980-03-11
Abstract: The method produces workpieces with fine needle-type bosses, the boss being ground to its finished dia. by a progressive grinding operation in a single pass. The work is thrust axially towards the grinder disc (7) through a stationary bearing (20) during this operation, the rotary and feed movement being imparted to it without side loading. To form a taper on the boss, the bearing can be slid at right angles to the axis of the work as this is fed forward. The grinder disc can run in a stationary bearing in a frame (11), while the work bearing is fixed to the machine bed. A feed slide travels on the bed in the axial direction of the work, being equipped with a drive mechanism for work feed and rotation free of side loading.

Title: Pressure sensor screw-fitting into IC engine block - has membrane moving rod acting on piezoelectric transducer
Inventor: KLEINSCHMIDT PETER DIPL PHYS
IPC: G01L23/10
Filed: 1980-05-16
Abstract: A piezo-electric transducer (20) is connected via a rod (26) to a membrane (15). The sensor is fot fitting into the engine block (13) and detects knocking. The pressure in the piston chamber acts on the membrane, whose resulting movement is transferred by the rigid rod to the piezo-electric transducer where it is converted into an electrical signal. The transducer consists of a piezo-electric plate on a metal plate (24). The rod is made of steel and may be hollow. The bimorphous transducer has an external thread (18) that allows it to screw into a threaded hole in the engine block. The metal plate faces the piston chamber and is in good thermal contact with the sensor's casing (17), which acts as a heatsink. The membrane has a built-in curvature that does not change sign when the membrane is heated by the burning gases. The membrane consists of a thin sheet of titanium, tantalum or tungsten. A ring may be located between the rod and the membrane. The advantage lies in simplicity and in the sensor's being fitted permanently into the engine.
