Title: Method and apparatus for the adjustment of boring tools
IPC: B23Q17/22
Filed: 1945-10-09
Abstract: 604,315. Boring. HAUSEN, A. E. Oct. 9, 1945, No. 26255. Convention date, Nov. 16, 1942. [Class 83 (iii)] A method of setting tools in a boring- bar comprises measuring apparatus such as a micrometer, set to the diameter of the bore required, mounted on a frame for movement in the direction of its measuring axis, one end of the frame abutting a dial indicator and characterised in that the micrometer is centred in relation to the boring-bar axis and then located against movement away from the dial indicator, movement in the opposite direction being permitted against spring pressure, the boring tool being set and checked again in a position at 180 degrees to the first position. The micrometer 1, or similar gauging-device, is first adjusted over the cylindrical part to which the bore to be machined is to correspond and is then laid in the frame 2 adjustable along the base 5. A tapered bush 9 is a sliding fit on the boring bar 6 and is brought into position between the measuring faces of the micrometer, the measuring axis of the micrometer and the axis of the bush and bar intersecting at right angles. When the micrometer has thus been centred in the frame, a stop 3 is moved against it and clamped by the screw 11 to prevent movement to the right, Fig. 4. The frame is then brought into position to adjust the tool 17 which should contact the face of the adjusting spindle 20 of the micrometer. The boring-bar is next rotated through 180 degrees and if the tool is accurately set it will contact the anvil 21. In order that a deeper cut may be given the tool for clearance purposes &c., a dial gauge 14 is mounted on a bracket 15 slidable in the same channel which takes the micrometer and is brought up to contact the arm of the micrometer, clamped and adjusted to give a zero reading. The tool is next adjusted by the screw 18 until the dial gauge shows the amount of extra cut required.

FUR MOTORISCHE KRAFTERZEUGUNG, 12, Freigutstrasse, GRAEMIGER, B., 29, Guggerstrasse, Zollikon, both in Z³rich, and LUDIN, W., 29, Ruhtalstrasse, Winterthur, both in Switzerland. Sept. 13, 1934, No. 26329. [Class 59] In a jet-pulverizer, passages or the like are provided through which, at least, a portion of the coarse material separated out in the pulverizer can flow back separately into the jet. In Fig. 1 raw material is fed into an inner chamber 15 and surrounds a mixing tube 4 which may be movable. The outer casing 1 forms with the chamber 15 an annular chamber 13 into which coarse material, thrown off by the vanes 6 surrounding the impact block 5, collects, and is again carried by the gas issuing from jet 2 through the mixing tube. The bottom of chamber 15 is provided with an orifice 16 coaxial with the jet 2 and forms part of the mixing tube. The coarse material picked up by the gas from the jet 2 passes through the orifice 16 and entrains raw material from the chamber 15, the amount of raw material entrained depending on the amount of coarse material already in the jet ; overcharging is thus prevented and an automatic adjustment of the feed effected. The amount of the charge of raw material is determined by the heap angle and additional coarse material falls thereon and overflows at 31 into chamber 13. In Fig. 5 the raw material fed in at 3 is entrained by the gas from the nozzle 2 and passes through an orifice 21 forming the first part of the mixing tube where it entrains the coarse material from chamber 22 and passes through the mixing tube 4. The flow of raw material to the jet is accelerated by the flow of air through passage 23 and when the coarse material in chamber 22 overflows into passage 23 the feed of raw material is restricted and automatic regulation effected. Air supply to the feed end of the mixing tube may be provided by surrounding the tube with a casing provided with inlet passages controlled by the deposit of coarse material, or the air supply may be provided by a pipe projecting above the surface of the raw material and terminating at the lower end of pipe 4.

Title: Process and apparatus for contacting two partially miscible liquids
IPC: C10G7/00
Filed: 1954-09-14
Abstract: <PICT:0772060/III/1> <PICT:0772060/III/2> <PICT:0772060/III/3> <PICT:0772060/III/4> A process for contacting a first liquid with a second liquid in three or more vertically superimposed treating stages, the second liquid being more dense than and partially miscible with the first liquid, comprises passing the two liquids concurrently and upwardly through a mixing zone in each stage, conveying the mixture of liquids from each mixing zone to the settling zone of the next highest stage, allowing the mixture to stratify in each settling zone to produce separate layers of light liquid and heavy liquid, conveying the heavy liquid from each settling zone to the mixing zone of the next but one lowest stage and conveying the light liquid from each settling zone via a weir to the entrance of the adjacent mixing zone, a liquid interface being maintained between the heavy and the light liquid in the conduit leading from each settling zone to the entrance of the adjacent mixing zone by means of the weir.  The process is applicable to the solvent extraction of petroleum oils, employing such solvents as liquid sulphur dioxide, phenol, cresol, nitrobenzene, furfural, aniline or ether, or mixtures of solvents, particularly for the purpose of removing low viscosity index constituents from the oils. The process may also be used in the acid-treating of caustic-alkali treating of mineral oils or in dewaxing, sweetening or other refining operations.  In Fig. 1, heavy liquid (e.g. phenol) enters tower 3 through conduit 11 and leaves through conduit 13, while light liquid (e.g. mineral oil) enters through conduit 10 and leaves through conduit 12.  Conduits 36, 37 and 38, which contain mixers 33, 34 and 35 respectively, constitute mixing zones, while the lower edges of plates 7, 8 and 9 constitute weirs.  Settling zones 70, 71 and 72 and the settling zone below plate 74 have light liquid-heavy liquid interfaces at 26, 27, 28 and 29 respectively.  Figs. 3 and 4 show modifications of the tower 3 of Fig. 1 in which liquid from settling zone 72 is refluxed to mixing zone 38 through conduit 80.  In Fig. 5, heavy liquid enters vessel 51 through conduit 91 and leaves through conduit 121, while light liquid enters through conduit 111 and leaves through conduit 101.  Mixing zones 251, 261 and 271 are divided into two sections by means of vertical plates 281, 291 and 301 respectively.  Mixing is provided by means of sets of perforated vibrating plates as at 371 or by means of a bed of packing material as at 331, while reflux also occurs around the vertical plates 281, 291 and 301.  Settling zones are indicated at 221, 231, 241 and 451, while the lower ends of conduits 471, 481 and 491 constitute weirs. The apparatus employed in the process may contain mixing zones which are inclined to the horizontal, while the apparatus shown in the drawings may be used in an inverted position.  Specification 689,974 is referred to.
Patent GB-730894-A (GB)
Title: Improvements in or relating to soap powders
Inventor: PARKE JOHN PEDLOW
IPC: C11D9/14
Filed: 1952-10-23
Abstract: A soap powder comprises soap, of which at least 50 per cent by weight is derived from unsaturated soap-forming acids, in admixture with sodium or potassium carbonate and disodium or dipotassium orthophosphate, the carbonate and orthophosphate being in such conditions that, when the powder is added to water, they dissolve before an appreciable amount of soap has dissolved.  This ensures that these compounds react with the salts of hard water before the soap reacts therewith and is wasted.  The unsaturated acids from which the unsaturated soap portion is derived may comprise rosin acids or unsaturated fatty acids containing a straight chain of at least 14 carbon atoms and liquid at 20 DEG  C. The acids specified comprise oleic acid, linoleic acid, linolenic acid, palmitoleic acid, liquid unsaturated polymerized whale, fish and linseed oil fatty acids or rosin acids or mixtures thereof.  Suitable oils for making the soaps comprise groundnut oil, sunflower seed oil, palm oil, linseed oil and rosin or mixtures thereof with more saturated oils, such as tallow and coconut oil.  Preferably at least 60 per cent by weight of the soap constituent is derived from unsaturated soap-forming acids. The soap powders may contain 5-70 per cent of soap and preferably at least 20 per cent.  To ensure that the carbonate dissolves before the soap, the carbonate may be added as separate particles to the soap particles, the particle size being within the usual range for soap powders; or the carbonate may coat the soap particles; or a molten mass of soap and carbonate may be sprayed together to form powder, the carbonate then dissolving in water at a greater rate than the soap particles.  To ensure that the orthophosphate dissolves before the soap, it must be external to the soap, either as separate particles or as a coating on the soap particles.  The proportions of carbonate and orthophosphate are at least 5 per cent and 8 per cent, respectively, by weight of the soap constituent.  The upper limit of both compounds is 40 per cent by weight of the powder.  Other adjuncts normally used in soap powders may be present, such as alkaline sodium silicate.

Abstract: 692,244. Delivering articles from hoppers. AKTIEBOLAGET MALCUS HOLMQUIST. Nov. 15, 1951. [Nov. 21, 1950] No. 26810/51. Class 78 (i). Cylindrical work-pieces are fed from a hopper 28 into a centreless-grinding machine 1 between a grinding wheel 3 and a counter-pressure roller 2 by a push rod 9 reciprocated at a rate which is equal to, or preferably a little greater than, the speed of the piece through the machine, the last-mentioned speed being determined by the oblique setting and rate of rotation of the roller 2. The rod 9 is attached to a slide 8 which travels along a guide on an arm 6 projecting from the frame 5 of the machine. A driving rod 10 secured to the slide passes between and is in frictional engagement with rollers 11, 12, the upper of which is mounted on an arm 13 pivoted to the framework. The roller 11 is rotatably mounted on the framework and is driven continuously by an electric motor through variable speed gearing. This motor drives also a shaft 17 carrying a cam 18 on which rests a pin 19 mounted in the end of the arm 13. A spring 20 tends to maintain the arm in its lowest position with the roller 12 in driving engagement with the rod 10, but when the roller is raised by the rotation of the cam 18, the rod 10 is retracted by the swinging of a pivoted lever 21. The slide 8 is pivotally connected to the lever 21 which is pivoted in a bracket 22 and has its lower end attached to one end of an anchored spring or chain 23. The movement of the lever is limited in one direction by an adjustable abutment 24 and in the other by an adjustable abutment 36. The timing is such that the rod 9 is moved forwards at a speed equal to or slightly greater than the feeding speed of the work-piece imparted by the roller 2. This compensates for the time lost on the return stroke and the distance between consecutive work-pieces is reduced to a minimum.
