Title: Tool to form loops at rope ends - comprises needle with clamp for drawing end axially along core
Inventor: ROSENBERGER LUDWIG
IPC: D07B1/18
Filed: 1977-12-23
Abstract: A loop capable of resisting tensile loading is formed on the end of a rope. Without being opened, the rope end gripped by a clamp on a needle-like device, is threaded into a zone of the rope some distance from its end, and is drawn through over a distance extending centrally in the opposite direction to the end of the rope. The device is then drawn out of the rope, and the rope end released; the zone enclosing the rope end being then tightened. Replaces splicing esp. for sailing boat ropes, which do not have to have their strands unwound. Whilst spliced joints present no problem to the expert, they still take up a good deal of time, and an unskilled boatman may make an inefficient loop which is a risk in itself.

Patent DE-2811400-A1 (DE)
Title: Surface hardening of workpieces by arc remelting - esp. cast iron camshafts, where local remelting is followed by slow cooling to prevent cracking and martensite formation
Inventor: REINKE FRIEDHELM DR ING
IPC: C21D5/00
Filed: 1978-03-16
Abstract: The workpieces are made of cast iron contg. carbon; and a path on the surface is melted by an energy beam, esp. an arc. Cooling then proceeds by the transfer of heat to the workpiece below the surface; and this cooling is retarded so that the austenite below the surface zone solidifying as ledeburite does not cool so fast that martensite is formed. The workpiece is pref. preheated so that after arc melting, the temp. of the workpiece underneath the molten zone is just below the lower transformation point A1. In conventional surface hardening, martensite is formed below the surface ledeburite, thus resulting in stresses which lead to cracks, e.g. on the surfaces of hardened cams. The process prevents the formation of martensite.
Patent DE-2814989-A1 (DE)
Title: Lifter mechanism for ring rail of spinning frames - using a variable-length driving belt regulated by a worm wheel
Inventor: SOCHA JOHANNES DR ING
IPC: D01H1/36
Filed: 1978-04-07
Abstract: Lifter mechanism for the ring rail of a ring spinning frame, which is driven by the action of a cam on a lifting lever whose motion is transmitted by means of belts to the ring rail, whereby an eccentric on the cam operating via a pawl and ratchet wheel and a worm and worm wheel effects a gradual shortening of the main lifter belt to produce a slow traverse of the ring rail which gives the desired package build. The lifting motion is altered smoothly without the transmission of shocks and vibrations to the ring rail.

Title: Stamp for electrical machinery laminations - has four punches working in sequence to stamp circular location holes
Inventor: BERGMANN EWALD ING GRAD
IPC: B21D28/22
Filed: 1978-04-12
Abstract: In the stamping of laminations for electrical machinery the variation in thickness across the width of the strip creates a difficulty in assembly. This is beacuase the thicker edges of the laminations will all lie on the same side of the stack. To overcome this problem the metal strip passes the press (10) which houses a large punch and die to stamp out the circular lamination. Inside the main punch are four smaller punches which stamp location notches in the lamination. These smaller punches work in sequence so that the location notch is in a different position in consecutive laminations.
