Patent DE-2505665-A1 (DE)
Title: Atmospheric pollution free plasma torch cutting - is carried out just under surface of a water bath
Inventor: RASCHE SIGURD DR
IPC: B23K10/00
Filed: 1975-02-11
Abstract: In the flame cutting of metal by autogenous or plasma torches using air or a nitrogen-contg. gas, both the workpiece and the plasma torch are immersed into a liquid bath, pref. a water bath, so that the cut is effected at a slight distance below the water level. The preferred plasma cutting jet is fluid-stabilised. This eliminates the emission of toxic gases, noxious fumes and dust into the environment completely. The liquid absorbs noise, which is thereby reduced from over 90dB(A) to under 70dB(A). The damaging ultraviolet radiation is also absorbed by the liquid. The cut workpieces suffer no distortion.
Patent DE-2508675-A1 (DE)
Title: Belt saw for cutting planks of wood - with several saw blades in parallel
Inventor: GEBERT FRANZ
IPC: B27B15/08
Filed: 1975-02-28
Abstract: The belt saw cutting operation is considerably speeded up by arranging several power driven saw blades behind the other on both sides of a vertical conveying plane of the trunk. The four blades rotate over two rollers each positioned on either side of the timber to be cut. Roller units are separately supported, independently adjustable, so that the saw blades may be clamped independently from each other. An adjusting device facilitates acceleration of the saw unit w.r.t. a vertical transporter.

Title: Electrical drive for rotating drum - having rotor attached directly to extension of drum with adaptor section for different sizes
Inventor: HEINEMANN OTTO
IPC: F26B11/02
Filed: 1975-03-11
Abstract: Rotating drum has electrical drive as an integral unit, the rotor being directly connected to an extension of the drum while the central stator is attached to the drum mounting. The rotor is mounted to the inner side of the drum extension, this being of cylindrical shape at least in the portion to which the rotor is attached. It can have the same dia. as the drum. or have a smaller dia. with a conical reducing piece or have a larger dia. with a conical adaptor from small to large. The stator is mounted on a hub which extends into the extension and which is firmly attached to the mounting. The width of the motor section can be varied for different power loadings. For use on drum mills such as pebble mills. The use of integral electrical drives is known but has been limited to drives of the same dia. as the drum. The invention claimed extends this principle by using a single size of drive for different drum sizes.

Title: Appts. determining angle of inclination - limits effect of disturbing vibrations of non-protruding member
Inventor: SCHEDROWITSKY SAWELY SOLOMONOW
IPC: G01C9/12
Filed: 1975-04-18
Abstract: The apparatus determines the angle of inclination especially in systems automatically controlling the position of the working components of coke levellers, land-improving installations such as drainage and soil conservation etc. Accuracy is increased by limiting the effect of disturbing vibrations of the non-protruding member. The angle is ascertained from the non-protruding member situated on the mounting axis. The inclination of the member is converted into an electrical signal. A vibration suppressor is provided for the non-protruding member. In the preferred embodiment this member is the the form of a ring (1) whose centre of gravity with respect to the mounting axis (3) is moved below the value of the square root of half the sum of the squares of the outer and inner radii of the ring.

Title: Connecting clamp for plastic gutter sections - resistant to high stress due to expansion and contraction caused by temp. change
Inventor: HAAGE KARL DIPL ING
IPC: E04D13/068
Filed: 1975-07-02
Abstract: Connecting clamp for gutter sections made of plastic e.g hard PVC comprises a self-adhesive strip which is applied to the inner surface of the clamp to provide sealing properties. The strip pref. consists of permanently elastic plastic material, e.g. based on butyl rubber, and is covered with a protective strip of e.g. oiled paper up till the time of its installation. The strip provides a firm adhesive joint between the components, and allows the clamp to withstand high stress due to temp changes.

Title: Water heater with protected heating element - has thin sheet metal surround completely enclosing elements and disposable when furred up
Inventor: ZEIER HANS
IPC: F24H9/18
Filed: 1975-07-11
Abstract: The water heater comprises a vessel with a heating element having a heat dissipating surround mounted with a sealed-off section. This surround (10) completely surrounds the heating element to protect it. The surround is made of thin sheet metal and is disposable when furred up. This obviates the necessity for any other defurring operations. The surround has a heat flow surface mounted in the heat distribution or evolution surface. The heat surface is compressed by elastic deformation of the surround (10) to bring it into flat, efficient contact with the necessary stability.

Title: Impact resistant sand blast nozzle - with insert of brittle wear-resistant material and casing of ductile impact-resistant material
Inventor: REININGER HANS
IPC: B05B1/00
Filed: 1976-01-29
Abstract: The cavity between the insert and the casing is filled with rubber-like material, pref. a synthetic or natural polymer organopolysiloxane-base elastomers, pure organic-base synthetic elastomers, or natural rubber, e.g. acrylic rubber, polychloroprenes and polysulphides. Rubber-like material completely absorbs impact energy which is not consumed by deformation of the casing or protective cap, thus protecting the brittle insert against breakage. Working life of the nozzle is therefore determined only by wear in the blast channel.

Title: Railway track signalling and emergency braking system - has track transmitter linked with visual signals to initiate emergency braking
Inventor: ZIMMER RUDOLF ING GRAD
IPC: B61L3/00
Filed: 1976-07-08
Abstract: The track signalling and emergency braking system for automatically- or manually-operated locomotives, comprises isolated track sections with AC generators and track-side transponders and signals. A further track-mounted signalling unit prior to a visual signal transmits a signal to the locomotive to indicate the stop or clear situation as shown on the signal gantry. This is registered in the automatic monitor and controller so that if the visual signal is ignored, when in the 'stop' condition, the actual train speed is compared with a specified max. speed and if necessary an emergency braking sequence is initiated. This is based on a retardation curve (BR) designed to bring the locomotive to rest within the safe stopping distance (BA).
