Title: Endless casting belt - comprises copper alloy belt welded with tin bronze before cold rolling to final size
Inventor: TUSCHY ECKHARD DR RER NAT
IPC: B22D11/06
Filed: 1977-01-17
Abstract: The belt is made of a pptn. hardening Cu-0.15% Zr alloy with or without 2.4% Fe. The alloy is rolled into strip of 4 mm thickness and cut to size with the two ends at an angle of 30 degrees or 45 degrees. The strip is butt-welded by the TIG process using a Cu-Sn alloy as the filler metal. The belt so produced is cold rolled to the final dimension of 2.5-2.6 mm with at least 30%, but better 50% reduction in area. The belt is finally annealed at 550 degrees C for 4 h for the Fe-contg. alloy or at 450 degrees C for two h for the Fe-free alloy. The quality of the weldment is checked by X-ray examination after welding and again after the final cold rolling operation before annealing. Tests showed that the strength of the parent metal and the filler metal was almost identical. Rolling and final heat treatment after welding the strip into an endless belt improves the mechanical properties, partic. the tensile strength. High strength and long service life are necessary for the belts which cover the casting wheels of continuous casting machines.

Title: Fluid source for photometric analyser - with heater for constant viscosity and flow rate of calibrating fluid
Inventor: FEHLAU ROBERT
IPC: G01N21/85
Filed: 1977-12-17
Abstract: A fluid source with a controllable flow rate, for use in photometric wet analysis techniques, is fitted with a controlled heating device, consisting of a heater and a thermoprobe, for the outflow area of the fluid container. The container in the outer casing consists of a corrosion-resistant material with a small thermal expansion coefft., such as alloy steel, for the calibrating fluid. A plunger has a clearance of 10-20 mu relative to the bore of the neck, through which the fluid reaches a connection to the piping of the analyser. A heating device with a heating element and a thermoprobe keeps the viscosity and thus the flow rate constant. This keeps the flow rate of the photometric calibrating fluid absolutely constant by varying the viscosity through the temp. The container and the outflow are easy to clean.

Title: Multistep metering circuit for industrial transducers - has switchable transducer groups and bridge compensation units and changeover switch between metering points
Inventor: GALKIN MICHAIL MICHAILOVITSCH
IPC: G01D3/00
Filed: 1978-05-24
Abstract: The multi-step measuring device is based on a bridge circuit whose diagonal (ab) is fed from a pulse source (1). The measuring transducers are arranged into two groups. Both groups of transducers are switched alternately via a selector switch (7) and compensating units (8-10) (9, 11). These compensate for the contact and circuit resistances.

Title: Permanent magnet operated switch - has two fixed and one pivoted magnet providing two stable positions
Inventor: ZACH WOLFGANG
IPC: H01H36/00
Filed: 1979-03-10
Abstract: A freely moving control magnet of a switch reduces the size of the unit by separating the actuating and switching sections. The holding and securing magnets (1, 3) are fixed while the switching magnet (2) is attached to a pivot (4) between the other two magnes. The space between magnets (2, 3) exceeds the spacing between the other magnets (1, 3). The repelling force of similar poles in the closing position of the switch due to magnets (1, 2) force magnet (2) towards magnes (3) while forces of the latter end to push magnet (2) to magnet (1). The reaction is taken up by friction resistance of switch contacts (21, 22).
