Patent PL-175718-B1 (PL)
Title: Heat transfer apparatus provided with a forcibly driven circumscribing scraper bar
Inventor: LI YAO-TZU
IPC: F25C1/14
Filed: 1994-06-16
Abstract: A heat transfer apparatus for processing a liquid continuously has a positive mechanical drive for a set of vertical whip rods each disposed in a vertical heat transfer tube. Each whip rod is free-standing on its lower end and is sufficiently flexible to conform closely to the inner surface of the tube as it orbits. The orbital drive propels the whip rod directly through a pair of horizontal, vertically spaced plates that engage the rods in loose openings that serve as fluid inlets from the drive plate. A motor rotates a drive shaft coupled to at least one of the drive plates through at least one eccentric crank. Each plate can be an opposed pair of plates with a separate eccentric drives 180 DEG  out of phase with one another for a self balancing. Another form of drive plate uses a rigid circular ring that mounts rod-engaging sleeves via a network of wires supported by the ring. Fluid distribution can also be from a water supply held between a fixed plate and the upper drive plate with gravity feed to each tube through a properly sized inlet opening in the upper tube end. To isolate the heat transfer process, various seals are used to transmit rotary power through a housing without conventional rotary seals.

Title: Method of and apparatus for producing mineral wool by free centrifugal spinning
Inventor: DUPOUY VALERIE
IPC: C03B37/05
Filed: 1999-04-22
Abstract: The invention concerns a method which consists in simultaneously feeding material (30) to be drawn out in fibres to at least two machines (1, 2) placed side by side, comprising a series of centrifugal wheels (7, 8, 9, 10) arranged in cascade and driven in rotation about axes all having substantially the same direction (main axis 13, 14), two consecutive wheels rotating in opposite direction. The melted material (30) is poured on the first wheel (7), accelerated and conveyed onto the second wheel (8), then optionally on the following wheels (9, 10), to be transformed into fibres by centrifugal ejection, the fibres being carried by a gas stream and collected by a receiving member. The main axes (13, 14) of two adjacent machines (1, 2) are arranged at a non-null angle, such that the two gas streams emitted by the two adjacent machines (1, 2) join and combine with each other. The invention is useful for making products based on mineral fibres.

Title: Substrate for epitaxial growth
Inventor: PERLIN PIOTR
IPC: H01L21/00
Filed: 2010-04-06
Abstract: A surface of the substrate consists in plurality of neighbouring stripe shaped flat surfaces of a width from 1 to 2000 mum. Longer edges of the flat surfaces are parallel one to another and planes of these surfaces are disoriented relatively to the crystallographic plane of gallium nitride crystal defined by Miller-Bravais indices (0001), (11-22) or (11-20). Disorientation angle of each of the flat surfaces is between 0 and 3 degree and is different for each pair of neighbouring flat surfaces. Substrate according to the invention allows epitaxial growth of a layered AlInGaN structure by MOCVD or MBE method which permits for realization of a non-absorbing mirrors laser diode emitting a light of the wavelength from 380 to 550 nm and a laser diodes array which may emit simultaneously light of various wavelengths in the range of 380 to 550 nm.
