Title: Flanged water vessels for fire prevention in mines - with airtight lids held by plastic clamps which are removed by the explosion
Inventor: THY JOSEF
IPC: E21F5/14
Filed: 1973-06-30
Abstract: To prevent evaporation and contamination of the water in vessels placed in mines to reduce fire risk after explosions, the lid must be fitted airtight, but be removable by the explosion or shockwave. The lid is fastened to existing vessels with flanged edges, by means of four plastic clamps, one along each edge of appropriate length. The upper surface of the clamp covers more of the flange than the under surface whose edge is bent backwards to facilitate fitting. The tightness of the clamp is determined by the hardness of PVC used. As an additional fastening, the known metal clamps can be fitted over the plastic ones.

Title: Converter for binary logic signal levels - converts them into higher potential signals levels, including telegraphy signals
Inventor: HOLTE STIAN DIPL ING
IPC: H04L25/02
Filed: 1973-11-21
Abstract: The input circuit is electrically separate from the output circuit delivering the high potential signals to transmission lines. The output circuit generates two signals symmetrical to the frame potential, corresponding to two logic levels, and a potentiometer delivers at its wiper voltages which control absolute values of the higher potential signal currents. A voltage clipping circuit flattens transitions between the signals corresponding to the two logic levels; and a bipolar constant current source with two complementary transistors is connected by its two terminals to the voltage source delivering the higher potentials, whose terminals are alternately connected to the transmission line, depending on which of the above two transistors is conducting, so that the flattened signals are applied to the line retaining their shape.

Title: Electromagnet with several exciting sources - has movable armature and uses subdivided pole shoes for additional control windings
Inventor: MEINKE PETER DR ING
IPC: H01F7/08
Filed: 1974-02-12
Abstract: The electromagnet consists of a magnetizable yoke, an exciting coil system and two or more pole shoes and an armature movable between the pole shoes which consists of magnetizable material and conductor loops. The face area of one or several pole shoes is divided into two or more non-continuous sub-areas. In the gaps between the sub-areas one or more current carrying conductors are laid which form part of control coil system fed from control sources. The parts of the control coil system carrying the control current are so arranged that the magnetic flux due to this control current leaving the pole shoe has a direction opposite to the direction in other sub-areas of this pole shoe. The arrangement avoids unwanted coupling between exciting system and control systems.

Title: Flow- and non return valve - is truncated cone with three radial separating cuts on top forming elastic flaps
Inventor: SCHREINER ERNST
IPC: F16K15/14
Filed: 1974-08-20
Abstract: A truncated cone-shaped body, has a flange at the base and a cone-shaped cut-out. The top of the truncated cone has through-cuts starting from the centre and extending radially (1, 1"), which create three triangle-shaped flaps. The flaps open when fluid flows in the direction of the cone top and close to flow in opposite direction. When the flaps are open, they form a flow passage centrally located in teh pipeline. This feature makes the arrangement suitable for applications, where fluids with amounts of suspended solids are handled. To increase the closing response or to render the valve suitable for applications in higher pressure ranges the flaps can be provided with moulded-in steel plates.
Patent DE-2451675-A1 (DE)
Title: Overflow valve for heating systems with thermostatic radiator valves - is adjustable to delivery of circulation pump to prevent flow noises
IPC: F24D3/02
Filed: 1974-10-31
Abstract: The overflow valve assembly located between the delivery and return branches of the circulation pump in the heating system has a spring-loaded valve and a thermostat identical to the one which measured delivery temp. The spring-loaded valve can be adjusted manually by turning a control knob to actuate the spindle acting on the spring until the temp. at the overflow valve matches the delivery temp., thus determining the pump delivery. When the radiator valves are throttled, the press. in the system increases and the spring-loaded valve in the overflow assembly opens automatically, drawing off the excess press.

Title: Heat-treating yarn for twist stabilisation - wherein continuously running yarn enters shrinker box immediately on leaving processing chamber
Inventor: BOUS KARL
IPC: D02J13/00
Filed: 1975-04-09
Abstract: Yarns and similar textile materials, esp. bulky yarns to be heat treated by means of steam, gas or air, are arranged in the processing chamber, into which the heat treatment medium is delivered intermittently, in the form of a wound package and drawn off under conditions ensuring that the yarn is exposed to the action of the processing medium sufficiently long for the twist to be stabilised. From the processing chamber the yarn goes directly to a shrinking device. The tendency of the yarn to form rings and loops is eliminated whilst the yarn is running, so that the outer layers of the spool are not exposed to an unnecessary long heating to ensure the treating of the centre layers. Yarn is already heated and has undergone a preshrinking prior to shrinking.
