Patent GB-1049110-A (GB)
Title: Grinding
Inventor: GOLDSBOROUGH KEITH
IPC: B01F27/93
Filed: 1964-07-14
Abstract: Apparatus for grinding particulate solids in liquids comprises a plurality of substantially parallel shafts extending within a grinding chamber, each shaft carrying within the chamber at least one disc-like impeller the outer circumference of which is in close proximity to the outer circumference of a corresponding impeller on an adjacent shaft, the corresponding impellers being rotatable in a common direction.  Preferably, the shafts are mounted vertically within the grinding chamber, there being an inlet for a mixture of liquid and particulate solids to be ground at or adjacent the bottom of the chamber and an outlet for liquid and ground solids at or adjacent the top of the chamber. Preferably, each impeller is circular, substantially unperforated and mainted concentrically with its shaft.  The corresponding impellers on adjacent shafts are either in the same horizontal plane or in different horizontal planes.  The distance between the peripheries of corresponding impellers may be between 0.25 and 2.25 inches.  The horizontal cross-section of the grinding chamber approximates to the combined outline of the impellers so that there is a general uniform gap e.g. 0.5 to 2 inches, between at least part of the periphery of the impellers and the wall of the chamber.  The number of shafts may be between two and eight.  The impellers and, if desired, the wall of the chamber may be made of, or coated with, polyurethane rubber as described in Specification 900,050.  There may be at least one baffle projecting inwardly from the interior wall of the chamber as described in Specifications 1,024,053 and 1,024,054.  Separation of the ground solid from the grinding medium after grinding may be effected by means of the device described in Specification 971,756.  In operation, grinding medium, which preferably has a mean particle size of 150 to 3000 microns, solid to be ground and liquid are fed into the chamber and grinding effected by rotating the impellers preferably at a peripheral speed of from 2000 to 4000 feet per minute.  The solid to be ground may be an inorganic pigment e.g. titanium dioxide.  Examples are described.

Title: Process for the treatment of plasticized cellulose ester sheeting
IPC: B29C67/00
Filed: 1951-12-12
Abstract: Thermoplastic sheeting of a plasticized cellulose ester of a paraffinic mono-carboxylic acid containing 2-4 carbon atoms in the molecule is passed through the nip between a pair of unheated, hard-surfaced rolls, the temperature of which is not allowed to rise above 100 DEG F. and preferably not above 70 DEG F., the pressure between the rolls being sufficient to reduce the thickness of the sheet by at least 10 per cent. and preferably by at least about 20 per cent.  The sheeting may be precooled to a temperature not over 40 DEG F. and preferably not over 10 DEG F. immediately before it is passed between the rolls.  The roll-speeds may be 5-150 ft. per minute, and the rolls may be cooled.  In an example a sheeting 7.5 mils. thick, made by hot, solventless extrusion from a cellulose acetate composition containing 27.5 parts of diethyl phthalate, 7.5 parts of triphenyl phosphate and 1.5 parts of titanium dioxide per 100 parts of acetate, is passed once through the nip between two unheated hard and smooth-surfaced steel rolls of 6 ins. diameter, both rolls being positively driven at 50 r.p.m. and urged together by screw-compressed springs sufficiently to reduce the thickness of the sheeting to 6 mils.  In another example, sheeting made from a composition containing 100 parts of cellulose acetate, 40 parts of acetyl triethyl citrate, 15 parts of mixed ortho- and para-N-ethyl toluene sulphonamides, 2 parts of cadmium selenide and 0.2 part carbon black, is treated in a similar manner.  The process removes surface blemishes and renders the thickness of the sheeting more uniform.

Abstract: 1314886 Control systems CHANDLER EVANS Inc 19 June 1970 [24 June 1969] 29994/70 Heading G4H In a control system in which pulses driving the member to be positioned are accumulated in a counter 30 (Fig. 1) to give a count representing the actual position and the required position is entered into error counter 14, the contents of the two counters are periodically compared to control the application of pulses to the member. As described a pulse width signal A (Fig. 2, not shown) is periodically applied to (1) a monostable 18 to clear the counter 14 and (2) a gate 10 via which high frequency pulses from an oscillator 12 are fed to the counter 14 where for each pulse input signal A they are added to the complement of the count in counter 14 which represents the piston of the shaft of a stepping motor 42. If the counter overflows during this addition a multivibrator 20 is reset to set output Q 2  to its "1" state, this state being transferred after a predetermined delay to the output Q 3  of multivibrator 28 so that pulses from low frequency oscillator 38 increment counter 30. If the counter 14 does not overflow multivibrator 20 remains set so that Q 3  = 1 and the counter 30 is decremented. When the addition of the pulses from gate 10 and the complement of the count in counter 30 exactly fills counter 14 NAND gate 44 is held in its "O" state to reset the multivibrator 26 and inhibit the application of further pulses to the counter 30. The apparatus may be used for electromechanical fuel control in a gas turbine.  (For Figure see next page)

Title: Improvements in and relating to heat transfer surfaces
IPC: F28F13/18
Filed: 1964-07-20
Abstract: A metal heat transfer surface is treated to provide thereon a plurality of microscopic areas, some (e.g. 10) having hydrophilic chracteristics and being interspersed with others (e.g. 20) having hydrophobic characteristics; the latter providing a plurality of bubble-forming points for a vapourizing liquid, and the hydrophilic areas constituting growth areas for the bubbles.  It is stated that on a metal heat exchange surface so treated, a bubble (25) forming on one of the hydrophilic areas will quickly assume a spherical shape (26) and will then expand to a size (such as indicated at 27), many times the size of the original formation.  The metal surface may be pitted by any known chemical, electrical, accoustical or thermal means.  In one example a stainless steel strip was etched by dipping for 5 to 10 mins. in sulphuric acid at about 80 DEG C, washed in water and then dipped for about 10 mins. in a dilute solution of ferric chloride.  Finally the strip was coated by brushing with an epoxy resin mixed with a hardener and thinned by a solvent.  After curing for 24 hours the strip surface was sanded leaving only the pockets formed by pitting, filled with resin.  In another example a sheet of medium grade emery paper was sandwiched between a strip to be treated and a backing strip and the lamination so formed was then hammered to cause the emery grit to indent the strip under treatment. After cleaning, a coat of polytetrafluorethylene enamel was brushed on to the strip and then wiped off leaving the identations filled with enamel.  The strip was then baked at 650 DEG F to cure the enamel.  In a further example a cleaned smooth strip of stainless steel was sprayed with enamel from a perfume atomizer, the spray being directed into a rising air stream so that only the smallest droplets are carried on to the strip which is suspended across the air stream.
