Abstract: 1,043,611. Feeding material to an extruder. BORG-WARNER CORPORATION. Jan. 3, 1964 [Jan. 23, 1963], No. 419/64. Heading B5A.  Plastic material is fed from a plurality of feeding zones, in succession to a screw extruder. Material from a hopper above feed zone 12, falls into the path of reciprocating ram 29 and is pushed out by it through opening 14 to screw extruder 11 to be extruded through die aperture 19, a little of the material passing in the reverse direction along grooves 22 to lubricate the extrusion screw 18. Whilst this is happening the valve 36a in the feed zone 13 is shut and ram 29a is withdrawn, to allow material from another hopper 26a to fall into its path ready to be fed to the extruder screw. When ram 29 reaches the end of its stroke, it actuates a switch (Fig. 3, not shown), which causes fluid-operated control means 46 to close valve 36 across aperture 14, withdraw ram 29, open valve 36a from aperture 16 and cause ram 29a to move forward to feed material to the extruder 11. When ram 29a reaches the end of its stroke, it also abutts a switch, causing the control means 46, to operate ram 29 again in the same way as before. In a modification, spring-urged ball-type valves are used in place of the fluid-operated valves 36 and 36a.

Title: Equipment for introducing materials into liquids and smelt metals
Inventor: BATES KENNETH W
IPC: C22B9/10
Filed: 1983-11-21
Abstract: For introducing gases, wires and powders to metal melts, a multi-ducted refractory body (11) is installed in the wall (14) of a vessel (15) for the melt. The body has passage closing elements (24, 34, 35) preventing melt entering the passages (A, B, C). Two passages (A and C) serve respectively for introducing gas, and fluidised powders, to the melt; each has a movable pipe (36, 91) (for gas or fluidised powder). Upon moving gas pipe (36) towards the melt, it dislodges closing element (24) whereby gas from the pipe can enter the melt via capillary bores (25). Similarly, by moving pipe (91), closing element (35) is dislodged whereby the fluidised powder can discharge from the pipe (91). Wire is fed along passage (B) to the melt: when it reaches the closing element (34) the wire can itself dislodge this element to gain access to the melt.A method of introducing substances to liquids related to use of this apparatus is disclosed, as well as metallurgical processes involving the method.

Abstract: PURPOSE:To improve picture quality at a highlight part, and simultaneously, to improve the picture quality at a low density part as well. CONSTITUTION:The subject picture processor is to quantization-process multi- level picture data into binary data, and the remarked multi-level picture data is divided into high order data and low order data by a computing element 23. The low order data is binarized by a comparator 15 by making a normalized uniform random number generated from a random number generator 24 or a dither value from a dither generator 25 selected by a selector 22a threshold. Then, this binary data is added to the high order data of the picture signal of a remarked picture element by an adder 14, and is binarized by the comparator 18 on the basis of the binary data of the picture element binarized before the remarked picture element by an arithmetic unit 13 by making plural weighted mean values of plural picture elements in the vicinity of the remarked picture element the threshold. At that time, density is preserved by allotting a density error to be caused at the time of binarization by the adder 16 or a subtracter 17 to the adder 16, etc., to the unbinarized picture elements around the remarked picture element.
