Title: Improvements in or relating to devices for laterally displacing hay or like materials lying on the ground
IPC: A01D78/00
Filed: 1957-03-29
Abstract: 843,831. Hay-making. VAN DER LELY N. V., C. March 29, 1957 [April 12, 1956], No. 10369/57. Class 6(3). A side delivery rake of the kind comprising rake wheels mounted in echelon formation on a frame and rotated by coming into contact with the ground, is characterised by the fact that the frame can be brought from one working position to another by mechanism which is operable from the driving seat of the traction vehicle to which the frame is attached. The coupling device 9 by means of which the rake is coupled to the lift links of the traction vehicle is identical with that described in Specification 827,737 and comprises a tube 25 in which the frame member 27 forming the connection between the beam 29 carrying the rake wheels and the coupling device 9, is rotatably housed, rotation of the member 27 through 180 degrees in the tube 25 resulting in the rake's being brought from one working position to another. The mechanism whereby this rotation may be effected from the driving seat of the traction vehicle comprises a lever 80 accessible to the driver of the traction vehicle and pivoted at 83 to brackets 84 and 85 rigidly secured to the tube 25. The foot 79 of the lever 80 is connected to a bar 73 fixed to the frame member 27, by means of a connecting rod 76, the connections at both ends of the rod being such as to allow a slight pivotal movement. Undesirable rotation of the member 27 in the tube 25 is prevented in one direction by a stop 88 and in the other by a spring 87. When it is desired to bring the rake from working position to another, the beam 29 is raised clear of the ground by means of the lift links of the traction vehicle and the lever 80 is moved to the position 80A, whereupon the foot 79, link 76 and bar 73 assume the positions 79A, 76A and 73A respectively, thereby turning the frame member 27 through 90 degrees. The momentum gained by the frame during this movement is sufficient to carry it through the top dead centre position, whereupon the lever is returned to its position 80, thereby forcing the beam 29 to assume a horizontal position. In order to reduce the working width of the rake for transport purposes, the frame member 27 is rotated through 90 degrees as before and a pin 91 mounted in an extension of the bracket 84 is inserted in a hole 90 in the lever 80, thereby locking the beam 29 in a vertical position.

Title: Improvements in or relating to fire extinguisher charges
IPC: A62D1/06
Filed: 1928-04-05
Abstract: 311,063. White, A. E., (Fyr-Fyter Co.). April 5, 1928. Chemicals.-In chemical fire-extinguishers, carbon-dioxide-producing charges are employed comprising chemicals which will not readily freeze and which will react efficiently at temperatures substantially below 0‹C. The acid charge consists of a sulphonic acid, preferably a halogenated derivative such as chlorosulphonic acid. This may react with a carbonate either in the dry state or in solution, with the addition of a non-freezing agent, such as calcium chloride. The latter may be replaced by ethylene glycol which, with the carbonate charge, may form the fire-extinguishing medium. Preferably, however, the carbonate charge consists of a solution of the more soluble sodium potassium carbonate to which is added ethylene glycol. An exemplary complete charge for a 2¢ gallon extinguisher comprises 1.72 fluid, ounces of chlorosulphonic acid reacting with 7 ounces of sodium potassium carbonate and 11.3 ounces of ethylene glycol in 14 ounces of water.

The brick arches A, B at the front of the furnace abut against the cast-iron transverse plates, the rear plate 2 being flanged along its upper edge to counteract distortion. Angle irons are inserted behind the rear plate 2 and the vertical cast-iron members 3 to support the skew-backs for the door arches and roof. The bricks B are wedge-shaped and the roof bricks C abut against them.
Patent GB-560375-A (GB)
Title: Production of delustered filaments, films and other products
IPC: D06N3/02
Filed: 1942-07-27
Abstract: Artificial filaments, films, or like materials having a basis of an organic derivative of cellulose and containing polymerised ethylene oxide are subjected to a delustring treatment with a hot aqueous medium.  The delustring treatment may be effected when the filaments have been formed into fabrics.  The delustred materials resist relustring by agents which normally have a relustring effect on cellulose derivative materials.  The ethylene oxide polymers used may range from syrupy liquid through waxy solid to rubbery compounds. Water-soluble compounds fully compatible with the cellulose derivatives employed are preferred.  Proportions of 1-50 per cent based on the weight of cellulose derivative may be used.  The filaments or films may be formed by dry or wet spinning or casting methods.  Fine or coarse filaments including artificial bristles and straw may be obtained.  The delustring liquid may contain soap, salts, pine oil, or tetrahydronaphthalene.  Wet steam may be used instead of hot or boiling water.  Cellulose ester or ether materials may be treated.  The delustred materials have an increased affinity for dyestuffs normally used for cellulose derivatives.  The materials may be dyed simultaneously with or subsequently to the delustring with hot aqueous media. Delustring may be effected simultaneously with a craping treatment of a fabric containing high twist yarns.  In an example, a solution of cellulose acetate in acetone containing an ethylene oxide polymer or molecular weight about 4,000 is dry spun to form filaments which are wound on to a bobbin and immersed in boiling water until delustred.  The water may contain a little sodium oleate. The delustred yarn is dyed by treatment with a hot aqueous liquid containing 1 : 4-dimethyl-aminoanthraquinone, sodium oleate, and "Celascour" (a mixture of turkey red oil, xylene, and water). Celliton Blue AF or Setacyl Direct Discharge Blue G may also be used. In another example the delustring and dyeing are carried out simultaneously.  In another example, cellulose acetate yarn, obtained by dry spinning a solution of cellulose acetate containing ethylene oxide polymer, is given a crape twist in the presence of steam and then woven with a low twist cellulose acetate yarn.  The fabric is then given a boil-off treatment in an aqueous bath at 98 DEG  C. to develop the crape and delustre the yarn.  In another example, a transparent film made by casting a solution of cellulose acetate containing an ethylene oxide polymer is treated with boiling water until the film has become opaque.  The strength and elongation of the film are improved.  Specification 487,652 is referred to.
Patent GB-417834-A (GB)
Title: An improved process for making crystalline sugar from wood sugar solutions
IPC: C13K1/10
Filed: 1934-04-09
Abstract: Glucose or xylose is prepared in crystalline form from solutions containing glucose, xylose, mannose and the like obtained by saccharifying woody materials by adjusting the proportion of mannose to a proportion of 5-10 per cent of the total sugar, effecting the crystallization, and separating the mother liquor.  A thick crystal pulp is preferably produced at temperatures of 35-50 DEG  C. while slowly stirring, and if necessary after seeding with the appropriate sugar, this pulp being freed from the mother liquor by centrifuging and covering with water.  The crystallization may be effected from solutions of high sugar concentration, for example, up to 85 per cent.  The desired proportion of mannose may be attained by adding a sugar rich in mannose, for example, from conifer wood, to sugar poor in mannose.  Alternatively, a part of the readily hydrolyzable hemicellulose from conifer wood may be dissolved out prior to complete saccharification, or a mixture of conifer wood and deciduous wood in suitable proportion may be saccharified in order to obtain a solution containing the requisite proportion of mannose.  When a solution to be crystallized contains more than 10 per cent of mannose, the desired proportion is attained by allowing crystallization to occur at ordinary temperature, separating the crystal pulp from the mother liquor on filter presses, then dissolving the pulp again, and recrystallizing according to the method referred to above, at 35-50 DEG  C.  In this process the temperature may be gradually raised while pressing off the crystal masses containing mannose, so that the crystallized sugar remains in the form of hard plates free from mother liquor. Examples are given.

Title: Bobbin case opener mechanism for sewing machines
IPC: D05B57/26
Filed: 1959-04-02
Abstract: 862,717. Sewing machines. SINGER MANUFACTURING CO. April 2, 1959 [April 4, 1958], No. 11310/59. Class 112 Lock stitching by hooks, frames. In a lock stitching machine, opener means for the bobbin case of a rotary hook comprise a finger for engaging a lug on the bobbin case to open a gap between the latter and stationary rotationpreventing means, cam means mounted for rotation with the hook and acting on a member carrying the finger to open the gap periodically, a base on which the member is pivotally and slidably mounted and which is angularly movable about the axis of rotation of the hook, and clamping means for securing the base in a position of angular adjustment. The arrangement is designed to provide for changing of the timing of the bobbin case opening mechanism by means accessible externally of a work-supporting post, without disturbing any other mechanism carried in the latter. A work-supporting post 11 carries a bearing bush 12 for a vertical, hook-driving shaft 14, the upper end of which is counterbored at 15 to receive a fixed plug 16 formed with a transverse slot 18. The rotary hook 19 is formed with a depending stem 20 having a tongue 21 disposed in slot 18. Stem 20 and plug 16 are secured together by a screw 22 passing axially therethrough. A finger 26 on the bobbin case 24 journalled within the rotary hook is disposed between a pair of shoulders 27, 28 on a throat plate 29 fixed to post 11 by screws 30. A lug 40 on the bobbin case is engaged by a finger 41, shortly after the hook beak 23 seizes a needle thread loop, to hold finger 26 away from shoulder 27, whereby the upper limit of the loop can pass through the gap therebetween. Finger 41 then moves away from lug 40, when finger 26 is drawn by frictional drag against shoulder 27, whereby the lower limit of the loop can pass through the gap between finger 26 and shoulder 28. Finger 41 is carried by a plate 42 formed with a circular opening which embraces an eccentric 45 fixed to stem 20. A radial slot 46 in plate 42 slidably engages a block 47 pivoted on a base plate 48 supported on post 11. Plate 48 is formed with a central aperture having a smaller segment 49<SP>1</SP> of the same radius as the top portion of bushing 12. The remaining segment 49<SP>11</SP> has a greater radius to provide a clearance between bushing 12 and plate 48. The under side of plate 48 is formed with an arcuate slot 50, and the outside edge 51 of plate 48 opposite slot 50 is concentric with the latter. The arrangement enables plate 48 to be adjusted angularly, when screws 54 passing inwardly through post 11 opposite the pins 53 may be tightened to engage edge 51 for shifting plate 48 to clamp the latter against pins 53 and to disengage segment 49<SP>1</SP> from bushing 12.

Abstract: 1,248,295. Reactors. JAPAN ATOMIC ENERGY RESEARCH INSTITUTE. 4 March, 1969 [5 March, 1968; 15 Oct., 1968], No. 11331/69. Heading G6C. A steam generating, heavy water moderated nuclear reactor is initially loaded with slightly enriched UO 2  fuel rod clusters and then, on the second and subsequent loadings, with mixed oxide fuel rod clusters, the mixed oxide fuel being natural UO 2  mixed with PuO 2 . The PuO 2  is a by-product from the burn up of the fuel loaded in the preceding fuel cycle. Slightly enriched UO 2  is used for the first fuel loading in order to obtain a relatively low order positive void reactivity. Because of this positive void reactivity the reactor must be undermoderated but with the mixed oxide fuel a well moderated reactor is permissible. This may be achieved without change of core structure by using fuel rods of smaller diameter in the second and subsequent loadings compared with those used in the initial loading. The mixed oxide fuel results in a negative void reactivity and hence good safety characteristics. The number of rods in each cluster may be varied on and after the second loading of fuel. The number of slightly enriched UO 2  fuel rods in each cluster may for example be twenty-eight, and the number of mixed oxide fuel rods in each cluster thirty-seven, the diameter of the former being 14À50 to 15À50 mm. and the diameter of the latter 12À94 to 13À87 mm.
