Title: Presensitized positive-acting sheet for use in planographic printing
IPC: G03F7/09
Filed: 1965-02-19
Abstract: 1,097,945. Photo-sensitive materials. MINNESOTA MINING & MANUFACTURING CO. Feb. 19, 1965 [Feb. 19, 1964], No. 7360/65. Heading G2C. A photo-sensitive material comprises a transparent support coated with a layer less than 0À001 inches thick containing a diazonium salt of a poly-complex, oxygen-containing acid (e.g. phosphotungstic acid) and a first oleophilic polymer and overcoated with a layer also less than 0À001 inches thick of a second oleophilic polymer and a pigment, the first polymer being soluble in a solvent for the diazonium salt but insoluble in a solvent for the second polymer. The material may be imagewise exposed through the support decomposing the diazonium salt and then applying a solvent for the second polymer which removes the decomposed salt and the corresponding overlying area of the overcoated layer leaving a positive dye image. This image may be fixed by overall exposure and then bleached to removing any residual colour of the diazonium salt and leave a correctly coloured proof. Three separate colour proofs are made using cyan, magneta and yellow dyes in the overcoated layer which are then combined and used in colour printing. Acrylonitrile/ vinylidene chloride copolymer is specified as the first polymer, polyvinyl formal as the second polymer and the diazonium salts are those of Specification 1,010,203.

Title: Improvements in or relating to vacuum cleaners
IPC: A47L9/22
Filed: 1933-03-14
Abstract: 394,629. Centrifugal fans. ELECTROLUX, Ltd., 153, Regent Street, London.- (Assignees of Inventia Patent-Verwertunga- Ges. ; 10, Herrenacker, Schaffhausen, Switzerland.) March 14, 1933, No. 7716. Convention date, March 14, 1932. [Class 110 (i).] A vacuum cleaner comprising a centrifugal fan suction unit driven by an electric motor on a. vertical shaft is supported by springs 28 during non-rotation of the motor. When operating, the fans 12 create a suction in the chamber above the wall 24 which causes a lifting of the motor-fan unit, and relieves in part the load on springs 28. Upon further lifting of the unit the end 33 presses upwards against a yoke 29 which normally rests on a fixed part of the casing, or compression springs. Springs 30 anchor the yoke 29 to the casing. Blocks of rubber or the like 31 separate the yoke 29 from the wall 20 of the suction chamber, and a similar ring 27 prevents the entry of air at atmospheric pressure. Air enters through a port 15, is filtered by a chamber 14, passes down a tube 16 and enters the fan chamber through a hole 17. The air is expelled through outlets 18, or by way of a pipe 19 for blowing operations. A resilient ring 23, of rubber or the like, has one end 25 clamped to the fan chamber, and the other 26 screwed to the casing. The springs 28, 30 may be in alignment and fitted with stops at their outer ends, or they may be combined into one spring, the motor-fan unit being suspended from the middle of the spring. In the latter case the one spring may be replaced by several springs.

The lever may have an elliptical or oblong aperture 19 into which the free ends of the clamping ring engage, so that in turning the lever the hooks 18 move towards or away from each other. In a modification the lever moves radially in respect to the cap 3 and is provided with converging earn faces which operate the hooks. Notches 11 may be provided to locate the hooks in the ' closed ' position and prevent unintentional operation of the lever. The cap may be of glass, earthenware or composite material. In the case of cans fitted with such closures, a lead, &c. seal may be attached to the lever.

A bit for a percussive drill has cutting inserts forming a chisel shaped cutting edge and means to move the inserts laterally to compensate for gauge loss. As shown, the bit may comprise a pair of inserts 12 slidable in a slot 11 in a drill head and having between them an inverted-V shaped space 25. A wedge 22 arranged in the drill head enters the space 25 between the inserts and is held in position by end 15 of a shank 16, a series of shims 19 between the head and the shank limiting the forward position of the wedge. The shims may be removed one at a time allowing the wedge to enter further into the space and force the inserts apart. Other methods of adjusting the gauge of the drill include inserting shims between the inserts and a central support on the head, Fig. 7 (not shown), mounting the inserts each on one base which bases may be moved apart by right and left hand threads on a screw, Fig. 8 (not shown), and providing the inserts and the slot in the head with corresponding corrugations, the inserts being removed from the head and replaced again in a position to restore the gauge, Fig. 10 (not shown).

Title: Method and apparatus for pneumatically sifting loose material
IPC: B07B7/01
Filed: 1967-02-21
Abstract: 1,135,913. Pneumatic sifting. MIAG MUHLENBAU UND INDUSTRIE G.m.b.H. 21 Feb.. 1967 [23 Feb., 1966], No. 8209/67. Heading B2H. In an apparatus for pneumatic sifting of loose material, e.g. for the separation and cleaning of grain crops, the material is caused to drop in a veil-like manner in a main coarse fraction sifting region against upward flowing sifting air which is subjected, before entering the main sifting region, to a pressure drop and, after leaving the region, to a pressure increase and a subsequent continuous acceleration and, finally, to a deflection and a subsequent expansion whereby a medium fraction is separated out. The apparatus comprises a cylindrical housing 1 to the bottom of which material entrained in sifting air is fed through an axially adjustable pipe 3 having a flared end 23. A baffle 4 mounted above the pipe 3 has a passage 5 through which the material is projected into a chamber 6 formed in the lower part of a frusto-conical insert member 11 in the upper part of which is provided an expansion chamber 12. A conical baffle 22 in the chamber 6 assists in deflecting the upward moving material downwards on to the upper surface 7 of the baffle 4 which is provided with a step 21 for uniform distribution of the material. The main sifting region 8 is formed by the annular space between the baffle 4 and the housing 1 and a resifting region 10 is defined by the longitudinally tapered annular space between the member 11 and the housing 1. The space 20 between the flared pipe portion 23 and the baffle 4 provides a nozzle causing a pressure drop in the air before it enters the region 8. The diameter of the lower end of the member 11 is smaller than that of the baffle 4 in the region 8 so that as the air enters the region 10 it slows down and its pressure increases. On leaving the region 10 the air is sharply deflected by means of a baffle ring 18 into the expansion chamber 12 where a medium fraction separates out. The air and the fine fraction flow via a hood 15 and a pipe 16 of adjustable flow cross-sectional area to a separator for recovery of the fine fraction. In modification, the material may be fed from above on to the surface of the baffle 4 and the sifting air blown or induced from below through apertures in the housing.
