Title: Improved screen for winnowing fans
Inventor: REAVES ROBERT STANLEY
IPC: A01F12/44
Filed: 1970-07-07
Abstract: 1,260,459. Winnowing fan. ALLIS-CHALMERS MFG. CO. 7 July, 1970 [18 July, 1969], No. 32909/70. Heading A1F. [Also in Divisions B2 and F1] A winnowing fan 11 of a combine harvester has at least one air inlet opening 21 provided with a self-cleaning screen comprising a number of spaced elements 27 flexible in their length and carried by, and circumferentially arranged around, a hub 22 mounted on and rotatable with the shaft 18 of the fan 16 adjacent to the inlet opening, the elements 27 projecting from the hub to an extent to overlap the periphery of the inlet opening. The elements 27 may be of circular cross-section and may be made of spring steel wire, which may be chromium plated, or of plastics materials, e.g. nylon, and in the latter case they may be formed integrally with the hub 22 which may be made of two parts 23, 24 clamped together. The elements 27 may project radially or tangentially from the hub and may be straight or curved. In operation, debris, e.g. leaves or stems, drawn up to the air inlet openings 21 by the suction of the fan, is prevented from entering the openings by the rotating elements 27. The debris is either chopped-up by the rotating elements to a size small enough to pass through the elements and into the fan, or is thrown off the elements by centrifugal force, thus keeping the entrance to the air inlet openings unobstructed. Also, due to their flexibility the elements vibrate as they rotate thus further aiding in dislodging debris from the screens.
Patent GB-798998-A (GB)
Title: Decelerating device
IPC: B41J19/02
Filed: 1955-11-17
Abstract: 798,998. Typewriters. UNDERWOOD CORPORATION. Nov. 17, 1955 [Dec. 8 1954], No. 32910/55. Class 100(4) [Also in Groups XIX and XXIV] The paper carriage of an accounting machine or other object movable linearly relative to a fixed member is yieldingly driven at a restricted speed and is decelerated and arrested by a stop which slides a limited amount when engaged by a projection on the object and is connected by a link to one member of an over-running clutch, the other member of which is rotated at a speed related to the maximum speed of the object. The two clutch members can rotate relatively to one another in one direction only and the speed of the second member is so chosen that the speed of the link connected to the first member cannot exceed that of the object. Tabulating movement of a paper carriage is arrested by the engagement of a column stop 35 forming a projection on the carriage with a stop arm 36 pivoted on a slide 39 on which is also pivoted one end of a link 59. The other end 61 of the link 59 is pivoted on a cap 62 fast with a cam and rotatable on a spindle 63. A casing 66 is also rotatable about the spindle 63, and within the casing and in tapered notches of the cam are spring-loaded balls tending to jam between the casing and the cam. Thus the speed of the cam, when rotated counter-clockwise by the link 59, cannot exceed that. of the casing. The latter is geared to a pinion 71 fast with one member 28 of another over-running clutch driven by a worm 32 constantly rotated by a motor, This other clutch limits the speed of the carriage during tabulating movement under the action of a spring, a rack 10 on the carriage driving the second member 31 of the clutch. As the stop arm 36 is struck by a carriage stop 35, the clutch 62, 66 acting through the link 59 prevents movement of the slide 39 at a speed greater than that of the carriage, and, as the pivot 61 of the link is moved round the spindle 63, its velocity component in the direction of carriage movement, and consequently the speed of the slide 39 and of the carriage also, is gradually reduced to zero. The carriage is released for a further tabulation by an arm 47 which, when raised, rocks a lever 46 to lower the stop arm 36 and rocks levers 54 and 52 to project an auxiliary stop 48. When lowered the arm 47 allows the auxiliary stop to be withdrawn by a spring 51 to release the carriage and allows the stop arm 36 to return to its effective position. The worm 32 also drives a pinion 12, when a dog clutch 26, 27 is engaged, so as to return the carriage. Specifications 401,904 [Group XIX] and 675,466 are referred to.

Substantially homogeneous beadlets containing one or more active ingredients are made by incorporating an aqueous suspension or solution of the active ingredient(s) in a hydrophilic colloid (e.g. gelatin, a gum, carrageen, an alginate or albumen), pouring the solution or suspension into a water-immiscible animal, vegetable or mineral oil whilst both phases are at a temperature above the gelpoint of the colloid, emulsifying by agitation and cooling the emulsion to between 0‹ and -70‹C. to coagulate and then harden the beadlets so formed. Examples relate to gelatin beadlets containing hydroxy cobalamine acetate; 17#-hydroxy-17α-methyl-estra-4, 9, 11- trien-3-one and a colourant.

Title: Desalination of sea water, using reverse osmosis, in vessels submerged at depths for sufficient hydrostatic pressure
Filed: 1967-07-19
Abstract: 1,141,138. Motor operated by variations of atmospheric temperature. A. P. PEDRICK. July 19, 1967, No.33055/67. Heading F1S. [Also in Division B1] Apparatus for the desalination of sea-water by reverse osmosis comprises membrane 3 in vessel 1' suspended at least 3, 500 ft. below the surface of the sea by a float which comprises a transparent diaphragm 33 incorporating lenses 34. Solar heat boils water 35 in a closed space below the diaphragm and expansion of the diaphragm applies tension to cable 31 and raises piston 6 to force desalinated water upwards in pipe 9. When the piston is at the bottom of its travel, water which has passed through membrane 3 flows through ports (not shown) into the space above the piston.

Title: Improvements in or relating to the preparation of steroids
IPC: C07J5/00
Filed: 1964-08-20
Abstract: A steroid 21-dialkali phosphate is obtained by treating a 21-hydroxy steroid with an organic phosphate ester in the presence of a dehydrating agent to obtain the corresponding steroid 21-organophosphate, cleaving the latter in an aqueous base to obtain the corresponding steroid 21-dialkali phosphate in aqueous solution and purifying the latter compound by selective extraction alternately with n-butanol, ether, water containing alternately hydrogen and sodium ions and freeze-drying the aqueous solution containing the 21-dialkali phosphate salt of the steroid. As organic phosphate ester there may be used an ethyl phosphate of the formula <FORM:1010031/C2/1> wherein R is hydrogen or lower alkyl and 2 is a strongly electronegative substituent, e.g. b -cyanoethyl phosphate, and as dehydrating agent a carbodiimide, e.g. dicyclohexyl carbodiimide, may be used.  The preferred 21-hydroxy steroid is 6a -methylprednisolone.  Pyridinium b -cyanoethyl phosphate is obtained by adding a mixture of pyridine and b -hydroxy-propionitrile to a solution of POCl3 in ether, treating the reaction mixture with barium acetate to obtain barium cyanoethyl phosphate, treating the latter with an acid ion exchange resin to obtain b -cyanoethyl phosphoric acid which with pyridine yields the desired pyridinium b -cyanoethyl phosphate.
