Title: Dry or semi-dry cold rolling of polyolefin sheet - for enhanced mechanical and optical properties without subsequent drying
Inventor: JENKS RICHARD HENRY
IPC: B29C55/02
Filed: 1978-01-17
Abstract: Thermoplastic sheet is cold rolled with a thickness redn. of 5-95% by passing between rollers having tangential velocities matched to the sheet speed and where the haul-off stress is close to the elastic limit for the material leaving the roll nip. The roll surfaces are soaked with a fluid coolant, but the relationship ZN/P (where Z is the viscosity of the coolant, N the sheet offtake speed and P the roll nip pressure) is maintained at values which result in partial or zero lubrication of the sheet surface, i.e. the sheet leaving the roll nip has partially or completely dry surfaces. Used for producing cold rolled polyethylen or polypropylene sheet or tape having advanced mechanical properties and transparency and free from voids or tears, e.g. for fruit packaging film. Higher roll nip pressures and haul-off stresses can be sustained than when cold rolling sheet with an interfacial lubricant film, resulting in greater strength, transparency, etc. Little or no liq. has to be recovered from teh drawn sheet or tape. Process condition variations are less critical than rolling with a complete lubricant film between roll and sheet surfaces.

Title: Deposition welding on valves for IC engines - via automatic machine for induction welding ring of heat resisting alloy onto head of poppet valve
Inventor: KOZLOV ANATOLY EFIMOVITSCH
IPC: B23K13/00
Filed: 1978-03-23
Abstract: The welding machine has a chute down which the valves slide one at a time and are tipped so the head of the valve drops into a jig fitted on the top end of a piston in a pneumatic cylinder. A second chute is used to feed a ring of heat resisting alloy over the stem of the valve so it drops onto the valve head. The jig is then driven sideways by a second pneumatic cylinder so a chuck can clamp the valve stem so the head and the ring can be rotated in a high-frequency inductor, thus welding the ring onto the valve head to form a valve seat. The jig is mounted together with the first pneumatic cylinder on a slide reciprocated by the second cylinder, between the loading and heating stations. Compared with similar, conventional devices, the invention is faster and more reliable.
