Title: HF coaxial line section - has outer dia. of insulation support made smaller than or equal to nominal dia. of outer conductor
Inventor: SPINNER GEORG DIPL ING DR ING
IPC: H01B11/18
Filed: 1977-07-22
Abstract: The coaxial line section has insulation supports between the inner and outer conductors and annular slots in the inner conductor or/and in the outer conductor for compensation of the capacitive error caused by the insulation supports. The outer dia. of the insulation support is smaller than or equal to the nominal dia. of the outer conductor of the smooth, fault-free line. The inner dia. of the insulation support is greater than or equal to the nominal dia. of the inner conductor of the smooth, fault-free line. The inner conductor and/or the outer contactor are fitted with two axially spaced beads in the annular space between the inner and outer conductors. The insulation discs are hooked in between the beads and the compensation annular slots join on the side of the two beads facing away from the insulation support.

Title: Paper sheet stacking system - uses intermediate pallet to forming auxiliary stack during changeover after which stack is raised for intermediate pallet removal
Inventor: BLOECKER HORST
IPC: B65H31/32
Filed: 1977-08-16
Abstract: The system continuously delivers flat sheets of paper, cardboard etc onto pallets. An intermediate pallet is inserted above the full one on changing pallets, the sheets being delivered onto it to form an auxiliary stack, while an empty pallet replaces the full one and is then lifted to take over the auxiliary stack. The auxiliary stack is lifted from the intermediate pallet, which is extracted, after which the stack is lowered onto the empty one. This can typically be done by the formation of a gas cushion between the stack and the auxiliary pallet, this being maintained during intermediate pallet extraction.

Title: Wind and wave power plant - has bucket wheels with power transferred to flywheels connected to main shaft
Inventor: VEECUMSEE DEVENDRA HIRALAL
IPC: F03D9/02
Filed: 1977-11-26
Abstract: The wind and wave power plant has a fixed construction, which is erected on the sea bed close to the coast. Alternatively, it can be a floating construction anchored on the sea. There is a number of bracket wheels (W) which can be raised or lowered to bring them into contact with the water surface.

Title: Winding starter spools for an open=end spinning machine - uses yarn withdrawn from the inside of an auxiliary package
Inventor: KAMP HEINZ
IPC: D01H4/48
Filed: 1978-02-22
Abstract: In winding starter spools for an open-end spinning machine, yarn from one of the psinning heads is wound as a special auxiliary package from which the core can subsequently be removed to permit re-winding on to starter spools from the inside of the auxiliary package, thus preserving the original direction of travel of the yarn. The auxiliary package core is a slightly tapered cylinder of six segments which are held in fixed positions by an internal spreader device permitting the diameter of the cylinder to be adjusted between at least two different values to facilitate its removal from the yarn package. The starter yarn is not reversed in direction with respect to the yarn forming the bulk of the spool, thus eliminating a potential cause of fabric faults in later processing.

Title: Playing head adjustment in magnetic tape recorder - feeds track sync. pulses to phase comparator which operates piezo-ceramic transducer to compensate recorded track deviations
Inventor: MANGOLD HANS DIPL ING
IPC: H04N9/797
Filed: 1978-08-31
Abstract: In a magnetic tape recorder, a colour television signal is recorded using a double head onto two tracks simultaneously. The tracks run parallel side by side with no spacing. Synchronisation pulses derived from e.g. line sync pulses are recorded on both tracks. During playback, after amplification and demodulation stages, the pulses are isolated and enter a phase comparator. Any difference signal is used to operate a piezoceramic transducer. This adjusts the playback heads to compensate for deviations in the recorded tracks, thus providing a continuous, automatic correction.

Patent DE-2903265-A1 (DE)
Inventor: KOPP WALTER
IPC: G03G15/16
Filed: 1979-01-29
Abstract: Apparatus for printing of toner images wherein characters to be printed are produced on an intermediate carrier (ZT); for example, a photoconductive drum and transferred at a printing station (US) onto a recording carrier (AT) with continuous movement of the recording carrier. In order to start and stop the movement of the recording carrier there is provided, behind the printing station, a feed means (VR) engaging the recording carrier (AT) which has a drive shaft (VRW) of a drive installation with an electromagnetic coupling (EMK) and an electromagnetic brake (EMB). In order to be able to swing the recording carrier (AT) to the intermediate carrier (ZT) and to swing it away, respectively, a polarized drawing magnet (HM) is provided at the printing station. During starting of the recording carrier the feed means (VR) are first set into motion by the electromagnetic coupling (EMK) and upon reaching the nominal speed the drawing magnet (HM) is energized so that it swings the recording carrier to the intermediate carrier (ZT). During braking of the recording carrier the drawing magnet is first activated so that it swings the recording carrier away from the intermediate carrier (ZT). Subsequently, the electromagnetic brake (EMT) is actuated and thus the feed means (VR) are brought to a standstill.

Title: Multicylinder internal combustion engine - has dynamic propeller type non-return valve in inlet connection to each cylinder
Inventor: LINDTNER MIRKO DIPL ING
IPC: F02B29/02
Filed: 1979-02-12
Abstract: An engine with four cylinders has a common suction manifold supplied with a fuel mixture from a carburettor. There is a separate branch from the manifold to each cylinder. A propeller type non return valve is placed in each branch. The valve is rotated by the incoming mixture to prevent reverse flow of exhaust gases and improve the charging of the cylinder with fresh mixture. The use of separate propeller type non-return valves prevents reverse flow from one cylinder into the common manifold and thence into the other cylinders which would happen with a common valve.

The two reception antenna are coupled to a phase comparator for detecting the spaced line conductor crossing points. The rear reception antenna in the direction of movement of the train is coupled to the information channel of a processor, with the phase comparator responding to the leading reception antenna passing acrossing point, to disconnect the rear reception antenna and couple the leading antenna to the information channel, with reconnection of the rear antenna to the latter before it passes over the crossing point.

Title: Cold pilger rolling mill for mfg. long tubes - where three sets of reciprocating clamps ensure accurate feeding of tube blanks into mill, esp. in triple strand mill
Inventor: UHLMANN OTTO
IPC: B21B21/04
Filed: 1979-03-10
Abstract: The mill includes a reciprocating roll stand contg. >=1 pair of rolls for rolling >=1 tube blank located on a mandrel. Two reciprocating clamps (I), (II) which always move in opposite directions, drive the blanks stepwise towards the rolls, and also rotate the blanks. On the exit side of the mill is another clamp (III) which rotates the finished tube without hindering its longitudinal travel. Between clamp (II) and the roll stand is another clamp (IV) which is reciprocated independently from clamps (I), (II) and holds the tube blanks while the directions of travel of clamps (I), (II) are being reversed. Accidental, premature entry of the blanks into the rolls, which would damage the blanks, is prevented.

Title: Adjustment system for polarised relay parameters - is by subjecting removable contacts to corresponding field to that for adjustment of permanent magnet
Inventor: SCHNEIDER HELMUT
IPC: H01H50/34
Filed: 1979-03-30
Abstract: The relay system has the relay contact contained in a sealed casing which can be removed from the remainder of the relay, with the permanent magnet adjusted via selective demagnetisation. Before the relay contacts are assembled with the remainder of the relay, they are placed in a magnetic field with a field intensity corresponding to that for the required adjustment of the permanent magnet. The relay contacts may be subjected to this field several times, before fitting them into place. The system presents subsequent variations in the operating parameters of the relay contacts due to the demagnetisation for adjustment of the permanent magnet.
