Abstract: 578,831. Typewriters &c. REMINGTON RAND, Ltd., and WOODGATE, P. W. , April 27, 1944, No. 2122/45. Divided out of 578,817. [Class 100 (iv)] A typewriter or like machine is provided with mechanism for feeding a sheet or sheets to a different extent from at least one other sheet in order to produce differential line spacing, the machine including co-operating rollers &c. by which all the sheets are releasably held while being typed and the line spacing mechanism including a clamping device which engages at least the front sheet and is mounted to move upon normal line spacing to maintain the front sheet in tension but upon release of the roller &c. is permitted to move into a predetermined line spacing position, carrying the clamped sheet or sheets without moving the remaining sheets. Figs. 3 and 5 show one construction provided in the machine as described in Specification 578,817 in which the platen carriage is provided with a second carriage movable on the first carriage to superpose sheets 33, 34 on to a sheet- 22 carried by the first carriage. All the sheets pass round the platen roller 5 between that roller and the usual pressure rollers 24 and the front sheet 34 is held by clamping fingers 49 against a plate 39 which is guided for upward movement on a plate 9 forming part of the second carriage. The plate 39 is urged upwardly by a spring 42 and when the rollers 24 are in operative position, the plate 39 is moved upwardly step by step by the spring in accordance with the normal line spacing movements of the platen. Upon moving the rollers 24 out of contact with the sheets on the platen, the plate 39 is raised by its spring 42 to an extent determined by the engagement of stops 45 on the plate 39 with adjustable stop screws 43 on the plate 9, the sheets 33, 22 remaining stationary. The clamping fingers 49 are then moved clear of the sheet, the plate 39 brought to its lowest position and the fingers 49 and rollers 24 restored to sheet engaging position. Fig. 11 shows a modification for use as an attachment to a standard typewriter and comprising side frames 121 connected by a curved front plate 109. The front sheet 134 is normally held by clamping fingers 149 against a carriage 139 having lugs 170 passing through slots in the plate 109 and connected by links 172 to levers 174 urged to turn in anti-clockwise direction by a spring 176. The upward limit of the movement of the levers is determined by pairs of adjustable stop screws 181, 182 carried by a shaft 180 which may be rocked by a finger lever 184 to bring either pair of stop screws into the operative position. The screws 182 co-operate with stop screws 187 on the levers 174 and the screws 181 co-operate with the edges of the levers.

Title: Method for oil depollution of industrial effluent
IPC: E02B15/04
Filed: 1966-01-17
Abstract: <PICT:1083243/C1/1> Oil is removed from the cooling and lubricating effluent of a cold-rolling mill by forming in the effluent an insoluble floc to coagulate and concentrate the oil, placing the effluent under pressure and dissolving pressurized air therein, releasing the pressure on the effluent liquid so that the air returns to the gaseous state and removes the floc and thus the oil upwardly by flotation, and skimming off the resultant layer of floc and oil. The floc may be formed by adding NaOH, KOH, or NH4OH to FeSO4 dispersed in the effluent. In the Figure, waste pickle liquor is metered by pump 10 into agitation tank 11, and caustic cleaning line waste is metered by pump 13 so that effluent pressurized by pump 12 to 40-80 p.s.i.g. is at pH 5-6.

Filed: 1925-01-27
Abstract: 250,349. Avery, Ltd., W. & T., and Taylor, J. W. Jan. 27, 1925. Counters of screw and nut type; stop-mechanism.-In a pump of the kind described in Specification 250,350, [CLass 102 (i), Pumps &c.], the actuating mechanism is controlled to give delivery of a predetermined quantity by means of a screw 9 in the actuating train adapted to be engaged by a traversing carriage 12 which is set to a selected position on a quantity scale on the fixed plate 11 and, when that quantity has been delivered, disengages itself from the screw and locks the latter against further rotation by means of a detent 35 engaging a slot 9a in the screw. When the carriage has been set to the selected figure it is raised by means of a handle 14a and crank pin 15 to bring a spring detent 13 into engagment with the screw 9, which is then turned by a crank handle to operate the pump until the carriage 12 moves a cam disc 28 loosely mounted on the screw and a pin 29a thereon engages a dog clutch 30a on the screw. Further rotation of the screw turns the cam 28 and causes the cam to depress the carriage and release it from the screw. This depression can take place only after the carriagehas completed its traverse and the full quantity of liquid has been delivered, as during the traverse a spring pawl 27 on the carriage slides on a fixed ledge 10<c> which is cut away at the end to allow the carriage to be depressed. When the cam 28 is rotated, a cord 31 on a pulley 29 carried by the cam operates a ticket feeding device 32 to bring a ticket under a type wheel 22 which prints thereon the quantity delivered. The wheel 22 is rotated by a pinion 24 which engages a fixed rack 25 during the travel of the carriage by a spring pawl 19. In another form, the carriage is set by means of a rotatable dial and pinion which operates a rack to raise a plunger a distance proportionate to the setting of the dial. The carriage is then moved until the plunger engages one of a series of fixed steps.

Patent GB-584876-A (GB)
Title: Improved apparatus for the countercurrent treatment of liquids
IPC: B01D11/04
Filed: 1945-01-31
Abstract: <PICT:0584876/III/1> Countercurrent treatment of immiscible liquids of different gravities and forming two phases is effected in a vertical tower divided into sections by horizontal plates 20, each plate being provided with risers 21 and downcomers 22 so arranged that each downcomer and each riser on one plate is vertically above a corresponding riser and a corresponding downcomer respectively on the plate below.  Caps 24 having serrated edges act as phase dispersers and are positioned at the ends of the risers when the lighter liquid phase is to be dispersed and beneath the plates at the ends of the downcomers when the heavier liquid phase is to be dispersed.  The downcomers and risers are positioned respectively on the plates upon interlacing circles or at the corners of interlacing triangles, squares or other polygonal figures.  When the heavier liquid is the continuous phase the lighter liquid is introduced at the botom of the tower, flows upwardly through the risers and is dispersed by the caps into streams of droplets which rise to the plate above and in so doing pass through the downflowing streams of heavier liquid.  The heavier liquid flowing through a given downcomer is approximately equally distributed among four downcomers on the plate below and each downcomer is supplied with liquid from four downcomers on the plate above. Redistribution of the lighter liquid from plate to plate takes place in a similar manner.  The tower is suitable for the solvent treatment of petroleum and coal tar distillates, lubricating oil distillates and kerosene and provides for intimate contact of the liquid phases without channelling, recycling and emulsification difficulties.  The tower is also suitable for vapour-liquid treatment.

Patent GB-493134-A (GB)
Title: Improvements in "true-to-scale" printing processes
IPC: G03F7/14
Filed: 1937-01-30
Abstract: 493,134. Photographic catatype processes ; photo-mechanical printing-surfaces. ANKENBRAND, E. Jan. 30, 1937, No. 2832. [Class 98 (ii)] A layer of colloid, e.g. gelatine containing a bichromate is exposed to light under an original and pressed into contact with a gelatine layer containing ferrous salts, this layer being thereby hardened by the action of the bichromate in the unexposed parts of the bichromate layer, the layers being prepared so that the reactants are present at the contacting surfaces in equivalent quantities. The ferrous salt layer will then take greasy ink at the unhardened parts. The ferrous salt layers may be prepared by casting a block of gelatine containing the salt with a series of separators, the edges of the block being rendered airtight, so that fresh surfaces may be used successively by removal of the used layers. Alternatively the layers may be formed as a roll with a separating strip, the unused surface being thereby protected from oxidation. The separators may be of paper, aluminium or celluloid. The gelatine blocks may also be prepared without the ferrous salts and bathed in a salt solution before use. In examples : (1) the ferrous salt layer contains gelatine, glycerine, oxgall, grape sugar, zinc white, Titan white, and ferric ammonium sulphate ; (2) gelatined paper is bathed in a ferrous sulphate solution containing glycerine ; (3) an emulsion containing gelatine, oxgall glycerine, Titanium oxide and zinc oxide is bathed in a solution of chrome alum, glycerine, grape sugar, and ferric ammonium sulphate. The layers are in all cases brought into contact with an exposed layer containing bichromate and may be used to prepare greasy ink prints from positive or negative originals, etching resists, relief blocks, or moulds. If three or more colour record negatives in half-tone with the screenings turned through 30‹ in the different records are used as originals, printing blocks for multicolour printing may be produced. The layers may be carried on supports of glass, metal, wood, celluloid, fabric, or paper.
