Title: Quartz glass lamp bulb pinch forming - uses L-shaped pinch jaws in mutually parallel and orthogonal arrangement
Inventor: OTT WOLFGANG
IPC: H01K3/20
Filed: 1974-08-01
Abstract: The pinch formation is intended for high melting point glass bulbs for electric lamps, such as quartz glass bulbs, whose pinch cross sections are in the form of a double T and contain sealed-in lead wires. Such quartz glass bulb pinching is produced by two pinching jaws, working on locally softened bulb up to the quartz glass softening point. The pinching jaws (2, 3) are L-shaped with shanks at right angles and parallel to each other. The pressing surfaces (5, 6) enclose an angle of 72 to 78 deg. to the pinch compression direction (A). This simple arrangement provides suitable bulb pinches without any defective seals of the lead-in wires.

Title: Knitting machine needle bed drive - has two separate and identical parallel gram driving linkages with different stroke lengths
Inventor: SOCHA JOHANNES DR ING
IPC: D04B27/08
Filed: 1974-11-12
Abstract: A process and appts. are claimed for the drive of the needle beds in a knitting machine, where the needle bars tilt on the upper edge of the comb plate against the counter movement of the guide bars, with two identical kinematic drives with different stroke lengths for the needle beds in their upwards and downwards movements, to tilt round a fixed point of the upper edge of the comb plate. During the under laying there is an additional tilting away from the upper edge of the comb plate during the upwards movement, with a forward tilting movement during over laying followed by tipping back into the extended position to be returned to the casting-off position. The system allows the guide needle bars and the needle bars to be manipulated against each other so that trouble-free stitches are executed under all operating conditions, the mechanism also being suitable for double-row knitting machines.

Title: Integrated guided transport system with interchange in transit - provides feeder transport with higher overall average speed
Inventor: NOTT KARL-JOSEF
IPC: B61B13/00
Filed: 1975-03-08
Abstract: The main transport network can be the conventional intercity railway (7) with non-stop express trains (1) between major centres, while intermediate places are served by a secondary system, illustrated in the example by a suspension monorail (8). The secondary system runs parallel to the main system's track for some distance, in this example directly above it. An automatic control system brings the feeder car and the express on to this stretch simultaneously, and the two are temporarily linked by couplings (11). Containers for either passengers or freight are then transferred from one to the other by hydraulic cylinders. When transfer is complete, interlock signals allow the couplings to be released and the express to be accelerated.

Title: Mould for kerb stone sections faced with fine concrete - has elastically mounted, instead of hinged, movable side of mould
IPC: B28B3/02
Filed: 1975-07-05
Abstract: The kerbstone sections have a coarse-concrete core, faced top and front with fine concrete. The mould is first filled with coarse concrete, then its slant side is moved to a new position by an hydraulic piston and the facing concrete added. When the side of the mould turned on a hinge, the movement opened gaps through which the fine aggregate escaped, leading to rapid wear on the equipment. To avoid this, the slant side of the mould is now attached to the side of the frame and to the hydraulic piston by deformable elastic buffers. By these means, the lower edge edge of the moving side of the mould is kept in good contact with the vibrating table that forms its floor, and leakages are avoided.

Pref. the half shell (60) can be combined with a second half shell (61) to form a cylindrical sleeve. Holes in the shell can be used to hold pencils whilst slits can be provided for sheets of paper or envelopes.

Title: Dynamic balancing of a guide roll for a papermaking machine - by means of balance weights fixed to a spring clamp ring engaging the roll interior
Inventor: BANZHAF HEINZ
IPC: D21F1/40
Filed: 1975-09-27
Abstract: In a roll for a papermaking machine, particularly a guide roll with a shell having a cap inserted in each end with associated bearing journals as well as balancing weights, the individual balance weights are fixed to the shell, but damage to this is avoided by the provision of clamping devices, e.g. spring brackets, tension rings, etc. Method permits the roll dimensions to be increased, despite the provision of balance weights which can be mounted in the most economic manner and without risk of roll breakage.
Patent DE-2546804-A1 (DE)
Title: Torque damper for motor cycle transmission - with elastic pads and asymmetric thrust ribs for thicker pads in drive direction
Inventor: ALBRECHT HANS
IPC: B62M17/00
Filed: 1975-10-18
Abstract: The motorcycle drive wheel is coupled to the transmission by interdigitated flange wheels, with radial ribs set in an interlocking pattern, and braced by elastic pad inserts. These dampen out torque vibrations to protect the transmission, especially when light alloy wheels are used instead of spoked ones. To increase the damping effect, without increasing the diameter of the damping discs, the pads are arranged symmetrically to the ribs, with the largest pad thickness in the drive direction. This optimises the pad damping and enables more ribs to be used, without increasing the diameter of the pads.
