Title: Spinning and twisting spindle
Inventor: WOLF HORST
IPC: D01H7/10
Filed: 1997-06-13
Abstract: The spindle (1) for a spinning machine, and especially a ring spinner or twister, has a coupling (20) in its drive transmission, to couple the drive unit to the rotor (3) sleeve. Preferably the drive unit is a drive belt (24), and the coupling has at least one carrier (23) ring disc (20), rotating on the stator (2) to be coupled to the rotor (3) without lateral forces. The ring disc can rotate on a carrier sleeve at the stator. The rotor (3) has a circular and cylindrical clamping cap (18) with a slit (19) at the side towards the ring disc (20) to take the carrier (23). The coupling (20) can move up and down axially to the rotor (3). The coupling (20) is permanently or ferro magnetic, and has an electro magnetic coil to mount the stator (2) on the spindle rail (6), with a reversible electro magnetic field, to move the coupling (20) up and down. A brake brings the spindle (1) to rest when the drive coupling has been disengaged. A damper (13) is at the spindle (1) mounting on the spindle rail (6), as a corrugated disc and/or a low viscose grease and/or a rubber elastic material. The roller bearings are rigidly secured to th e stator (2) and rotor (3).

Title: Melt guiding method in a polymer injection nozzle
Inventor: KERSCHENLOHR HORST
IPC: B29C45/30
Filed: 1997-07-16
Abstract: In a method for directing polymer melt in an injection nozzle (10) feeding an injection mould a single melt stream is divided into several streams passing through the nozzle body (14) to a collecting chamber (29) at the front of the nozzle. The individual streams are turbulently recombined at a central area (38) of the collecting chamber (29) after following an inward spiralling path. The injection nozzle (10) has a conical projection (31) with an outer surface (30) forming a collecting chamber (29) with the inner conical surface (32) of the front part of the nozzle housing (11). Individual flow channels (26) through the nozzle body (14) enter the rear of the collecting chamber at inlets (28). Guiding surfaces (34, 35) from the inlets (28) form a spiral flow path to a central area (38) of the collecting chamber (29). A nozzle opening (23) to the tool cavity (F) forms a seating surface for a shut off needle (19).

Title: Control circuit with protection circuit for discharge lamp
Inventor: YAMASHITA MASAYASU
IPC: H05B41/24
Filed: 1998-01-14
Abstract: The supply circuit for a discharge lamp includes a protection against abnormalities i.e. to switch off the supply if there is a failure. To cover temporary abnormalities two protection circuits are connected in parallel. One circuit isolates the supply when the abnormality persists over a set period and the other circuit operates for short abnormalities, during which time the first circuit maintains the supply. The two systems provide protection without the whole circuit supply tripping out because of transient problems. The supply circuit has a constant voltage supply which is blocked when the two protection circuits identify a problem.
