Title: Tanker pneumatic granular discharger - has annular compressed air inlet tanker base to clear residue
Inventor: THURESSON BENGT RUNE VERNER
IPC: B65D88/70
Filed: 1976-07-21
Abstract: The airstream of a tanker discharge, for granular or powdered contents, converges towards the delivery pipe. The tank's truncated conical outlet is shrouded by a tapering cover, with a clearance gap. Compressed air emerging at the cover nozzles is directed downwards by the gap. The tank (1) outlet (1a) is enveloped by an overlapping (7a) cover (7), terminating at the delivery pipe (4). The cover has nozzle holes (10) and carries an annular air supply dispenser pipe (6a). The parallel gap (9) between cover and tank can be divergent if the distance piece (11) is dispensed with. A cover of different cone angle is then welded directly on to the tank.

Patent DE-2652898-A1 (DE)
Inventor: MUELLER KARL HEINZ ING GRAD
IPC: H03L7/093
Filed: 1976-11-20
Abstract: In Doppler radar devices for measurement of distance or speed, it must be possible to synchronise the oscillator over a very wide frequency range. To form the deviation between the oscillator frequency fO and the synchronisation or Doppler frequency fD, a digital filter (9) with periodic weighting function h(t) is connected in series before the oscillator (24), its data input (D) is connected to the synchronising frequency (fD), and its clock input (T) is connected to the oscillator output (25). The data input (D) and the output (14) of the digital filter are connected to the inputs (D, A) of a multiplier (10), which is connected between the digital filter (9) and the oscillator (24). The circuit arrangement makes it possible to synchronise the oscillator over the whole range of the Doppler frequency, from zero (stopped) to the Doppler frequency which corresponds to the highest speed. <IMAGE>

Title: Cable twisting rotor roller protection - has a film of wetting fluid held on roller surface to prevent wear
Inventor: MUTHMANN WALTER
IPC: F16C19/52
Filed: 1977-04-19
Abstract: To protect the plastic carrier rollers for the rotors of a cable twisting machine (to prevent wear from foreign material clinging to them), a film of wetting fluid is held on the running surfaces of the rollers. The wetting fluid is pref. driven by an air stream at an angle of >90 degrees in a spray against the roller surface, and against its rotation. The wetting fluid is pref. applied at a thickness of 2 mu m the pref. medium being an anti-static fluid such as transformer oil. The fluid film prevents the build-up of localised hot spots so that wear is prevented.

Title: Prodn. of semiconductor device with several chips in wafer - provides thin wafer sections for deposition of chips with connecting strips on thicker sections
Inventor: GAMO HIROSHI
IPC: H01L21/329
Filed: 1977-04-27
Abstract: The chips produced in the semiconductor wafer have each a pn-junction and are spaced from each other in horizontal and vertical rows. Prior to formation of different semiconductor chips, the sections of the wafer, in which the chips are to be formed, are thinner than the remaining chip sections. The thicker sections remain as a number of connecting strips in a checkerboard or grid pattern. Within the regions surrounded by the connecting strips are formed several mesa ribs for each section in the form of a circular or closed cloops after the formation of the individual semiconductor chips. The mesa ribs separate a part of the respective chip pn-junction from the adjacent pn-junction parts. Finally the different semiconductor chips are separated.

Title: Siphon in hydraulic pipeline with pump boost - has corresponding turbine on falling side of siphon
Inventor: KOERBEL WILLI DIPL CHEM DR
IPC: F04F10/02
Filed: 1977-07-25
Abstract: The object of the proposed system is to employ the principle of a hydraulic siphon in a liquid pipe line in places where the obstacle to be traversed cannot be overcome by the naturally available pressure. in order to operate the siphon a motor driven turbine pump is inserted in the upstream side of the siphon. On the downstream side a turbine driven generator is inserted in order to reclaim a substantial part of the pumping energy. Where a very high obstacle has to be surmounted the pumps and turbines can be in cascade in order to keep pressures at a reasonable level. The use of pumps allows pipe lines to be run over obstacles where otherwise expensive tunnels would have to be driven through them.

Title: Hydrodynamic brake with float housing in vent valve - has float specific gravity chosen to operate only in pure air and not fluid mixture
Inventor: VOGELSANG KLAUS ING GRAD
IPC: F16D57/04
Filed: 1978-03-15
Abstract: The hydrodynamic brake vent valve remains open as long as air flow through and also so that the escape of operating fluid from the operating chamber is prevented. The vent valve (28) has a float housing (130, 132) contg. a float (135) and two connections (28a, 28b) for the vent line. One connection (28b) in the upper part of the housing has a valve seat (134) against which the float can be pressed. The specific weight of the float is so selected that it only maintains an upward thrust in pure operating fluid and not in an air-fluid mixture.

Title: Nutrient media filling in petri discs - by mechanised disc cover lifting and controlled pouring valve
Inventor: KOELMEL KLAUS DR MED
IPC: C12M1/22
Filed: 1978-03-21
Abstract: In a device for the filling of Petri discs with nutrient media, a bracket on a moving plate causes the disc cover to slide up and leave a slot between cover and bottom glass. The discharge opening of the pouring valve enters into this. The solenoid valve which connects up the storage vessel is controlled by a time switch. Two pairs of contact springs ensure that the filling operation takes place only when a partly opened Petri disc is present. This replaces the manual operation by an automatic germ-free process.
