Title: Process and apparatus for extracting starch and gluten from a dough of wheat flour
IPC: C08B30/04
Filed: 1965-07-29
Abstract: <PICT:1094145/C3/1> In a process for extracting and separating starch and gluten from a dough of wheat flour, wherein a wash liquid entrains the starch and carries it out of a treatment zone while gluten forms into lumps in the treatment zone, the gluten is caught and pushed through the zone, whereby small gluten particles or lumps stick to or are absorbed by the caught gluten lumps, and the wash liquid is caused to discharge from the treatment zone without accumulating therein.  In one embodiment (Fig. 1) dough is introduced at 5 into one end of a trough 3 from which gluten is discharged at 7. Rotating shaft 1 bears various means 2 for working and conveying the dough transversely and longitudinally of the wholly or partly perforated bottom of trough 3, which is also provided with pipes 8-11, fed from pipes 12 through which wash liquid, e.g. water or starch milk, is sprayed on to the dough.  As the starch is carried away through the perforated sections 14, the remaining lumps of gluten are squeezed and spread between sabre-like members 21 and the trough bottom, and are repeatedly lifted out of the trough by scrapers 18 and returned thereto.  Small gluten particles are collected by the lumps during their passage towards exit 7.  The wash liquid is continually withdrawn via collectors 30 and pumps 29 from perforated bottom portions 14, and may be recycled to return small gluten particles to the treatment zone.

Patent GB-860454-A (GB)
Title: Method and apparatus for the polymerization of olefines
IPC: C08F10/00
Filed: 1959-09-29
Abstract: Olefins are polymerized at low pressures by catalysts consisting of organo-metallic compounds and compounds of the transition metals with recycling of the olefin to be polymerized by exposing the olefin at a lower than polymerization temperature to liquefying pressures, the liquid olefin being introduced into the polymerization reactor without expansion where the pressure conditions are such that it evaporates in a quantity sufficient for the removal of the heat evolved in the polymerization, the olefin then being withdrawn and returned to the liquefaction cycle.  In addition to this olefin, further olefin may be circulated through the system.  The pressure may be the same throughout the circulation and solvents having a boiling point of more than 120 DEG  C. are preferably used. Propylene and butene-1 are specified olefins, while the usual Ziegler-type catalysts are listed.  The process may be carried out in the absence of a solvent (two such examples are given) while apparatus for carrying out the process is described.

Title: Improvements in and relating to hydraulic ram drives for underfeed stokers
IPC: F23K3/12
Filed: 1939-12-30
Abstract: 536,777. Liquid-pressure engines. CLARKSON, A. H. (Machinefabriek Geb. Stork & Co., N.V.). Dec. 30,1939, No. 33101. [Class 69 (ii)] In a hydraulic drive for an under-feed stoker comprising a piston working in a cylinder to which liquid is supplied under control of a main valve operated at variable speeds by a continuously rotating pump-driving shaft, the supply-passage of the cylinder is quickly opened before the feed-stroke by means of an auxiliary valve which remains in cut-off position during opening of the main valve and is then quickly opened. The arrangement causes the feed-strokes to be made at the same speed notwithstanding the variable speed of the main valve. The main valve 19 shown in Figs. 2 and 3 is intermittently rotated by a worm 17 on a sleeve 14 provided with a ratchetwheel co-operating with a pawl on a rock-shaft 10 which is operated by an eccentric 8 on the motor-driven pump-shaft 7. The stroke of the pawl, and consequently the speed of the valve, is adjustable by means of a hand-wheel. The valve is provided with a port 31 for successively opening passages 27 ... 30 leading to the front and rear ends of two ram-cylinders. The valve is provided with an auxiliary valve consisting of a slidable sleeve 33 which is moved in opposition to a spring 34 by co-operation of dogs 37, 38 on the cover 36 and the sleeve. In the outer position of the sleeve, ports 35 therein register with ports 21 in the main valve. When the port 31 is opening communication with the passage 27 or 29, the dogs hold the sleeve in the inner position, and the ports 21 are closed. When the port 31 fully opens the passage 27 or 29, the dogs disengage, the sleeve is moved outwards, and the ports 21 are quickly opened to establish connection with the ram-cylinders during the feed-movement of the ram. Additional dogs may be provided for controlling the sleeve when the port 31 opens communication with the port 28 or 30 to effect return-movement of the ram. A duplicate valve-arrangement for controlling two additional rams may be provided.
