Title: Extrusion die for multi core composite - filaments offers stable long-run operation
Inventor: OKAMOTO MIYOSHI
IPC: D01D5/36
Filed: 1970-08-17
Abstract: Die for forming composite filaments has several cores of one filament material dispensed in a matrix of a second material. The core streams discharge into a chamber which converges at an angle Theta of =75 degrees and which is fed with an annular and pref. also an axial stream of the matrix material. Pref. subsidiary passages sheath each core sub-filament in matrix material (co-axial or eccentric). For preparation of multi-core filaments or for manufacture of very fine filaments by subsequently removing the matrix material. Die design maintains stable core and matrix patterns throughout long prodn. runs - the flow path of the core filament streams is almost linear to avoid material hang-up and degradation. Sheathing of each core stream by matrix material avoids internal coalescence of the core streams.

Title: Device to direct objects into separate streams - uses pivoting guides and lever system controlled by passage of objects
Inventor: BAUER EVERHARD
IPC: B65G47/71
Filed: 1974-07-26
Abstract: The objects (1) arriving through one pair of guides (2) are directed to a number of outlet channels (4, 5, 6) by pivoting guides (11, 7) driven by a connecting rod (10) and a cam or crankshaft (8, 12, 13).

Title: Vibration gear lever mounting - with split bearing shells mounted in housing using soft elastic ring
Inventor: HEYARTZ RUDOLF
IPC: F16H59/02
Filed: 1974-12-21
Abstract: The gear selector lever is fitted with a spherical bearing (10) which is located in a spherical bearing shell (7) mounted in the support housing (4). In order to reduce transmission vibrations on the gear selector linkage the spherical bearing shell is spaced from the support housing by an elastic ring (6) which has weakened sections for improved elasticity.
