Patent DE-2522855-A1 (DE)
Title: Hot rolling ingots into tube with uniform wall thickness - where ingot is rotated before entering piercing mill
Inventor: UHLMANN OTTO
IPC: B21B23/00
Filed: 1975-05-23
Abstract: This is an addn. to 2505769, which described the mfr. of seamless metal tubes, where a red hot ingot is straightened, descaled by a high pressure spray, and fed into a rolling mill for piercing and stretching using a mandrel and several skew rolls. In the present invention, specifically prior to rolling, the ingot is rotated on its longitudinal axis at a peripheral speed corresp. to the magnitude and direction of the forces exerted by the rolls on the ingot. The pref. device consists of a long guide-cage which is rotated on its axis and contains rows of guide rolls arranged round the periphery of the ingot on axles which are at 90 degrees to the longitudinal axis of the cage, the guide-rolls being spring loaded in the radial direction. Ingots which are very long w.r.t. their dia. can be rolled to tubes with a uniform wall thickness, because the rotating guide cage prevents distortion of the ingot.

Title: Coupling element for underground mining machines - is esp. for roller coal cutters, connecting control line with contacts
Inventor: FROESE WILFRIED
IPC: G01R31/50

They control through a relay each (19-21) circuits (26-27) of signaling device (28, 29) or a circuit (25) of an electric unit (11).
Patent DE-2531866-A1 (DE)
Title: Sound absorbing wall element - exploits coincidence effect of resonance with penetration velocity to damp surface waves
Inventor: BSCHORR OSKAR DIPL ING DR
IPC: G10K11/16
Filed: 1975-07-17
Abstract: A sound absorbing wall element has a sealed surface and high mechanical, corrosion and thermal resistance. It is constructed to utilise the coincidence effect so that the velocity of the surface waves of the wall element is matched to the penetration velocity of the sound waves in the surrounding medium to be damped. Special border suppressors prevent penetration of the sound into the body of the wall. The separate impedance of the wall elements is equivalent to the wave resistance of the surrounding medium, and the surface waves in the wall element are reduced by the resistance of the wall surface. Honeycomb or wave-formed matter in the wall can be used to increase the frequency range of the exploited coincidence effect.

Title: Supercharged IC engine crankcase ventilation system - with a flow limiting orifice and supplementary air supply
Inventor: MARX WILHELM
IPC: F01M13/02
Filed: 1975-07-18
Abstract: The crankcase ventilation system for superchanged IC engines comprises a pipeline (5) from the sump (1) to the inlet side of the blower (2), embodying an orifice (6) to limit the max. flow regardless of blower speed. In addition, a spring-loaded valve (7) upstream of the orifice can admit air to the system to avoid an excessively high vacuum, minimising the risk of explosive mixture conditions in the crankcase. The system also reduces blower fouling, which is further diminished by fitting a filter (8) to the supplementary air inlet.

Title: Boring tool setting gauge - has micrometer for direct precision setting and alignment of cutter on boring bar
Inventor: EICHHOLZ WILLI
IPC: B23Q17/22
Filed: 1975-07-26
Abstract: The micrometer gauge is used for setting the boring cutter accurately relative to the boring bar centre in high precision boring of holes. The gauge is placed directly on the boring bar for cutter setting and the gauge can be clamped by magnetic force, by clamping screws or by clamps. The gauge has an adjustable stop in the form of a built in micrometer. This stop is brought directly into contact with the cutting tool tip. The micrometer reading can be used directly without any conversion calculations. The gauge has a contact surface which ensures that the centre of the boring bar, the cutting tool tip and the centre line of the micrometer are correctly aligned.

Title: Articles distribution appts. - has parcel marking equipment and station transmitting marking on magnetic tape and to waiting stations
Inventor: TUEXEN HANS H
IPC: B65G47/50
Filed: 1975-11-05
Abstract: The apparatus moves articles or parcels delivered in containers or on goods vehicles and distributes them to wating stations, each with a transport route or a receiving distination. The plant has a number of off loading stations (A-D) for the incoming containers or goods vehicles of which each is provided with an off loading conveyor and a belt conveyor (2a-2d). The conveyors automatically move the parcels to marking equipment (4a-4d) positioned at each off loading station. Behind the marking equipment (4a-4d) the parcels are guided on a transport rack (1) with an adjoining switching station (9). At the switching station its attendant reads the marking of the past moving parcels. After each read marking the attendant starts a corresponding magnetic tape device (11a-11d) and transmits by a microphone the read marking or other receiving data of the parcel onto the magnetic tape. At the same time the attendant activates a key (12) of one of the number of waiting stations (a-m) through which the parcel provided with marking corresponding with its destination is guided. In the waiting station the parcel is automatically removed from the transport track (1).

Title: Burst duct restraint for nuclear plant - comprising multilayer band of metal strip with plastic deformation
Inventor: HOFFMANN JUERGEN
IPC: G21D1/02
Filed: 1975-11-14
Abstract: An anchorage or restraint for pipes, esp. for steam or hot water ducts in a nuclear power plant, comprises a band passing around the druct and anchored in a concrete wall. The band is endless and is composed of numerous superimposed layers of metal strip (one or more strips wound round several times). The band passes round the duct and one or more anchorages. Band esp. passes around two bolts fixed in plates partly cast in the concrete and is doubled back around the druct. Part of the band may itself be cast in the concrete, so that a concrete plug or bolt passes through its loop. Device is for restraining a burst duct. The band is stressed into the plastic range, in the event of a burst, so that the energy is absorbed over a relatively longer distance and with a lower maximum force, than with a band composed of cables operating in the elastic range. Also due to the absence of complicated spring-like characteristics, the maximum force is easier to predict.

Title: Roof mounted extractor fan with horizontal discharge - has sound absorbing cylinders arranged vertically on discharge
Inventor: KIMPEL HELMUT ING GRAD
IPC: F24F7/02
Filed: 1975-12-20
Abstract: An extractor fan (3) is held within a housing with a base which fixes onto a roof curb. The housing has a lower section (1) which curves upwards and an upper covering section (1a) which curves downwards. These leave an annular gapbetween them on the outside of the housing and the fan discharges horizontally between them. A vertical cylindrical slab (2) of acoustically absorbing material is fixed to the edge of the lower section (1). A similar cylinder (2a) is fixed to the edge of the upper section (1a) radially outside the first cylinder so that there is a vertical annular gap between them. The discharged air is turned to flow through this gap which acts as a silencer. The vertical arrangement makes replacement easier.

Patent DE-2613287-A1 (DE)
Title: Shortening the setting time of cold hardening adhesives - contg. e.g. polyvinyl alcohol resin by passing through a heating zone before application
IPC: C09J5/06
Filed: 1976-03-29
Abstract: The bonding or setting time of cold-glues e.g. PVA glues, synthetic white glues and cold-glues that do not set in absence of air, is shortened by passing the glue as it issues from a supply reservoir and before it is applied to the adherents, through a heating zone. Used in the furniture and construction industries. Setting time is shortened by =50% without the need of special heated store-rooms where the glued-together adherents used to be brought to quick-setting temp. Setting temp. can be closely controlled, thus reducing risk of warping of the components.

Patent DE-2622300-A1 (DE)
Inventor: MALASEK FRANTISEK DIPL ING
IPC: B65H65/00
Filed: 1976-05-19
Abstract: To retain the end of the thread reserve formed on the bobbin edge during the winding operation on a winding machine, especially on an automatic cross-winding machine, after the formation of the thread reserve the floating thread end which occurs is directed by means of an air stream into the winding region of the actual yarn body and is fixed by this. For this purpose, the end face of the bobbin is assigned the mouth of a blow-in tube for blowing the floating end of the thread reserve into the winding region of the actual yarn body. This allows an effective thread fixing by the simplest means.
