Title: Electrochem. oxygen content sensor - for engine exhaust tubes using clamping contact between electrolyte and connector flanges
Inventor: FRIESE KARL-HERMANN
IPC: G01N27/407
Filed: 1973-09-01
Abstract: An electrochemical sensor of the oxygen content in the exhaust gases of internal combustion engines consists of a tube made of ZrO2 with an external coating of Pt and an internal longitudinal conductive strip as the inner electrode. The strip ends in a recess at a flange of the tube. The flange of a connector is kept in contact with it by an unsulating ring pressed against it by a union nut. This is a simpler and cheaper means of contacting than brazing or a fused glass joint. It eliminates high pressures against the thin-walled electrolyte tube or heat-resisting compression springs. A tube (19) made of ZrO2 with a Pt coating (12) is held in the housing (16); its top flange (21) with the top end of the conductive strip (14) is fixed by the flange (24) of the connector (25) through a copper or nickel washer (36). A heat-resistant insulating ring (29) with a copper or nickel washer (35) seals it against the housing (16). Another seal (37) closes the gap between tube shoulder (17) and the housing shoulder (18). The flange (24) rests with a clearance relative to the housing (16) in a recess (22).

Patent DE-2403765-A1 (DE)
Title: Sieve for melted plastics gives continuous throughput - without surge during sieve replacement and permits flushing of sieve
Inventor: FRITSCH RUDOLF PAUL
IPC: B29C48/691
Filed: 1974-01-26
Abstract: A sieve unit for melted plastics comprises two parallel ducts, each contg. a replaceable sieve, a main cut-off valve downstream of the sieve, a discharge opening with its own cut-off valve at or upstream of the sieve, and a further valve upstream of the sieve, this being also pref. a main cut-off valve. The ducts near the main cut-off valves are pref. shaped to avoid dead zones, more specif. with curved portions contg. the valve seating. When replacing one sieve, the associated downstream valve is fully closed, the further valve is throttled; the sudden increase in available volume in the duct resulting from the introduction of a new, empty sieve, e.g., in 1/10th sec., does not cause feed to be abstracted from the other, operational duct, since the throttle acts as a barrier; therefore the total throughput continues uninterrupted. Also, the discharge permits the branch to be flushed through with a charge of the matl.
Patent DE-2405670-A1 (DE)
Title: Automatic pipe cutting tool with feed mechanism - is of light weight and facilitates exact automatic rotation of pipe
Inventor: ROLLER ALBERT
IPC: B23D21/10
Filed: 1974-02-06
Abstract: The body of the pipe cutter has an axial bore for the pipe which is to be cut, and a radial guide slit, in which the cutting tool is mounted. A cover ring connected to the body by bolts closes off the front of the cutter. A coaxially arranged guide ring is located in a circular recess of the cover ring and has an outward extending cam which fits into a slit in the cutting tool. The feed mechanism sits in a bore of the cover ring and comprises an eccentric, via whose shaft a sleeve is displaced on whose mantel surface is a unit which releases the connection to the eccentric, when the cam-shaped lever is moved back to its starting position by a spring, after its swivelling motion. In this way a moment of rotation can only be transmitted in one direction.
Patent DE-2406341-A1 (DE)
Title: Two way poppet valve with bellows seal - has poppet shrouded in a tubular deformable bellows to isolate activation chamber
Inventor: KEMMLER ALFRED
IPC: F16K41/10
Filed: 1974-02-11
Abstract: A two-way valve for controlling the flow of aggressive fluids employs a tubular bellows to provide a positive sealing of the actuator chamber. Flow of liquid through the duct is controlled by a poppet mounted on the end of a spindle coupled to an actuating piston. The poppet is shrouded by a deformable bellows tube manufactured from an elastomer, or other similar material. The bellows is formed with a flange section that is sandwiched between the two body halves. A sleeve is located between the two body halves. A sleeve is located between the bellows and the spindle and has smooth grooves along its length, to facilitate deformation of the bellows. When pressure is applied to the piston, the poppet interrupts through flow by locating on a mating seat.
Patent DE-2409834-A1 (DE)
Title: Coal shearer with foremounted crusher roll - maximum and minimum flow pressure switches use valve to link or part pump and adjuster
Inventor: LANFERMANN WILLY
IPC: E21C27/08
Filed: 1974-03-01
Abstract: Coal shearer as a conveyor guided machine has a foremounted crusher or sizer roll which rotates on an arm fitted with a two-way cylinder, the arm to one side of the main machine frame and used to carry the roll motor as in 2357559. When the roll is the down position, two pressure switches allocated to the adjusting cylinder space or feedline loaded by the roll in this position take effect, one switch responding to maximum and one to minimum fluid pressure. When the low pressure switch operates, a subordinate valve between pump and cylinder links these two for flow purposes. When the high pressure switch operates, however, the valve connects the cylinder space to the sump. For use in workings where there is a firedamp hazard, the valve should be actuated by a pressure medium controlled by a magnetic valve which in turn is operated by the pressure switches and enclosed in a pressure-proof pocket within the hydraulic haulage on the machine.

Title: Glazing coating application process - uses centrifugal vapouriser discs on opposite sides of item conveyor at different angles
Inventor: SCHEJNIN JEWGENIJ I
IPC: B05B16/00
Filed: 1974-05-28
Abstract: The coating is applied to the surfaces of the items by vaporising solutions in suspension in two chambers (1, 2), one behind the other along the conveyor. One of these is turned through 180 deg. in relation to the other, and each contains centrifugal disc-type vapourisers (5, 6, 7). One of the discs in each chamber (5) is mounted rigidly to one side of the conveyor axis (3) with its jet directed perpendicularly towards the latter, while the two others (6, 7) are at the other side with their jets at an acute angle to this axis. They are so arranged that the jets from all three do not intersect. The system is particularly for the application of glazing to washbasins.

Title: Film viewer attachment for projectors - device produces image on projection table in daylight at low bulb loading
Inventor: KOWARIK WALTER
IPC: G03B21/10
Filed: 1974-08-21
Abstract: A fil viewer for viewing of films has an image gathering and transformation device which produces a projected image of the film from the projector on the surface on which the projector stands and just in front of it. The viewer has a height adjustment device which allows it to be used in conjunction with any conventional projector unit. In this way full projector bulb power is not necessary and darkening of the room in which the film is to be viewed is also unnecessary. Longer projection bulb life is thus ensured.

Title: Belt or chain conveyor for tree-trunks - with sideways tilting devices to roll-off the logs
Inventor: PERSSON JAN
IPC: B65G47/94
Filed: 1974-08-30
Abstract: The links of a double strand chain conveyor, carrying cross bars to locate the logs, are supported, at appropriate places, by two parallel rails one on each side of the main supporting beam. Each of the rails is supported on two parallel links so that, by operation of a power cylinder, either can be raised to tilt the conveyor and cause a log to roll off. This device is simpler in construction and can be controlled more easily to eject logs where required than other known designs.
