Title: Method of processing plastics sheet or strip material to form a product suitable for extrusion
IPC: B29B17/00
Filed: 1970-11-19
Abstract: 1329023 Extruding scrap plastics sheet H KOCH 19 Nov 1970 [5 March 1970] 55041/70 Heading B5A Scrap plastics material, in sheet form, is fed to the circumference of a rotated hollow cutting roller whereon it is wound into an increasing thickness which is forced, by pressure rollers located around the circumference of the cutting roller, as continuous strands through openings which are provided to the hollow interior of the roller and which have an inlet, from the exterior of the roller, comprising heated edges which exert a cutting action on the wound sheet, and act also to fuse the cut edges from successive sheet coils into the continuous strands. A conveyer means located in the interior of the roller acts to divide the strands into lengths which it conveys out of the roller, to storage, or to an extruder. A sheet of greater width than that of the roller is gathered together during feeding thereto.

Abstract: 1369439 Separating particles from gases HOCCOM DEVELOPMENT Ltd 18 Nov 1971 [20 Nov 1970] 55182/70 Headings BIT and B2P Particles, e.g. of oil, are separated from an aerosol by passing it through inlet 15 into a perforated rotor 13 which supports radial vanes 18, the rotor being driven by motor 11 at such a rate that the particles are precipitated on the vanes or the wall 21 of the rotor and are then thrown off onto a surrounding annular wall 22. The purified gas flows up to an outlet mesh 25 above the casing 10. The upward motion of the gas drives the separated. coalesced liquid up the inner surface of wall 22 so that it passes through inlet 24 to drain pipe 27. A layer of soft porous material may be provided on the inner face of wall 21, on the forwardly-facing surfaces of vanes 18, and on inwardly-facing surface of wall 22. Preferably the pores of the porous material are much larger than the particles to be removed from the aerosol. The porous material may be foamed polyurethane or polyethylene. Alternatively, a felt of fibrous material could be employed

Title: Improvements in processing machines, for example timber grinding mills
Inventor: SANDBLOM HENRY
IPC: H02P29/00
Filed: 1968-12-18
Abstract: 1,241,330. Control of two motors. ALLMANNA SVENSKA ELEKTRISKA A.B. 18 Dec., 1968 [19 Dec., 1967], No. 60191/68. Heading H2J. [Also in Division G3] In a timber-grinding mill, an asynchronous motor 11 drives a grinding-stone, the logfeeding chains being driven by a direct current motor 13. Signals proportional to the voltage and armature current of the motor 11 are fed to an emitter 17 providing a pulse train whose frequency represents the power consumption of the motor. The output signal from the emitter 17 is compared with a reference signal, and the difference signal controls the speed of the motor 13. The difference signal also actuates a counter 28 for indicating the power-consumption of the mill, data processing, or for control purposes. Voltage peaks are prevented from influencing the counter by means of a discriminator 21 which responds when the difference signal exceeds a set value to block AND gates 24, 25. An analogue signal proportional to the speed, voltage, or power of the motor 13 is converted into a frequency-signal, and, when a no-load peak is absent, the output signal from the gate 24 is integrated in the counter 28 to represent the quantity of wood fed to the mill. A powersignal is supplied to the counter through gate 25, which is also blocked when there is a no-load peak, and is integrated to constitute a measurement of grinding energy. In a modification, the power consumption of the stone-driving motor is detected by a magnetostrictive torque gauge whose output signal is divided by a signal representing the amount of wood fed to the mill. The latter signal is derived from a digital converter and integrator, the integrated signal being passed through an AND-gate, having a blocking circuit, to a mean value converter. The signal from this converter is proportional to the quantity of wood per unit of time, the length of the measuring period being set by a time switch. The signal from the divider is applied to a recorder which registers the grinding energy consumed per cubic metre of wood fed to the mill, Fig. 2 (not shown). In a further embodiment, signals representing the power of the stone-driving motor and the rate of feed are applied to respective mean value units associated with a divider and a recorder, Fig. 3 (not shown).
