Title: New and useful method for the prevention of damage to plants by nematodes
IPC: A01N63/30
Filed: 1962-07-23
Abstract: A method for the prevention of damage to plants by plant parasitic nematodes comprises applying fungi directly to the surface of seeds, for the control of nematodes of the genus Ditylenchus, Meloidogyne, Anguina, Aphelenchoides, Pratylenchus, Paratylenchus, Xiphinema or Radolphus, wherein spores and/or mycelia of one or more fungi of the genus Arthrobotrys, Dactylaria, Dactylella, Cystopage, Euryancale, Trichothecium, Stylopage, Nematoctonus, Helicocephalum, Triposporina or Cephalosporium or members of the Zoopagales are used. Advantageously, the fungus is developed on a substrate, e.g. moistened straw or compost, and the seeds are treated before or during sowing with the substrate permeated with the fungus.  In a further embodiment, the seeds, before or during sowing, are wetted with a suspension of spores and/or mycelium fragments.  Sugar beet seeds and onion seeds, for example, are treated with an aqueous suspension of spores or mycelia of Arthrobotrys cladodes Drechsler.ALSO:A method for the prevention of damage to plants by plant parasitic nematodes comprises applying fungi directly to the surface of seeds or plant seedlings, for the control of nematodes of the genus Ditylenchus, Meloidogyne, Anguina, Aphelenchoides, Pratylenchus, Paratylenchus, Xiphinema or Radolphus, wherein spores and/or mycelia of one or more fungi of the genus Arthrobotrys, Dactylaria, Dactylella, Cystopage, Euryancale, Trichothecium, Stylopage, Nematoctonus, Helicocephalum, Triposporina or Cephalosporium or members of the Zoopagales are used.

Title: Improvements in or relating to straight-bar knitting machines
IPC: D04B11/00
Filed: 1954-10-01
Abstract: 787,994. Knitting-machines. MONK (SUTTON IN ASHFIELD), Ltd., S. A., and MONK, B. A. Jan. 2, 1956 [Oct. 1, 1954; April 15, 1955], Nos. 28285/54 and 10846/55. Class 74 (2). A welt transfer bar for transferring a separately knitted welt to the needles of a straight bar machine is mounted on arms in front of each needle bar and is advanced to transfer the loops on the points of the welt bar to the needles by causing the points to engage the needles when the needles are in their knock-over position, the sinkers are then advanced to extend over and to hold down the welt as the needles and transfer points are raised together to effect the transfer. In one arrangement, Figs. 14, 15, the welt bar 97 carrying the transfer points is mounted at each end in a block 95 slidable on a pivoted arm 94. The arm 94 is secured to a shaft 90 and the block 95 is connected through linkage 98, 99 to a shaft 91. Rotation of the shafts 90, 91 is controlled through linkage from cams on the mainshaft. In an alternative arrangement, Fig. 1, the welt bar 10 is mounted on arms 13 pivoted at 15 on the narrowing machine frame. The arms 13 are, at the appropriate moment, swung to bring the points into alignment with the needles, the normal fashioning mechanism control then being modified to allow the points to engage the needles and effect the loop transfer. In a further arrangement the welt bar is mounted on arms which pivot on arms which are themselves pivotally mounted on the frame of the machine, the arms being given the necessary movements to cause the loop transfer in co-operation with the needle movement. The welts on a multi-section machine may be connected up to the take-up straps through welt rods prior to the transfer operation so that the welts are all transferred to the needles simultaneously. Two take-up rollers may be provided so that during the completion of a garment the next welt to be transferred may be positioned ready for transference to the needles.

Title: Improvements in automatic control systems
IPC: H02P23/00
Filed: 1954-10-04
Abstract: 777,594. Governor transmitting mechanism. WOODWARD GOVERNOR CO. Oct. 4, 1954 [Oct. 8, 1953], No. 28542/54. Class 57. [Also in Groups XXXV, XXXIX and XL (c)] In a governor arrangement for the automatic control of the speed of a prime mover, the controlling displacement of the throttle comprises the algebraic sum of displacements proportional to the deviation of the speed from the desired value, the rate of change of speed and the " absquare " of the rate of change of speed. The " absquare " of a quantity is defined as the product of the quantity and its absolute value. The invention may also be applied to an electric control system (see Group XXXV). In the mechanical embodiment described, the speed of an engine 30 is controlled by a throttle 31 through an hydraulic servomotor 520. The deviation displacement is provided by the rod 503 of the centrifugal governor 500 repeated by the hydraulic servomotor 510 to rod 512. For small deviations the displacement of rod 512 is transmitted to the servomotor 520 through the linkwork 526, 531, 542, 544 . . . 548. The multiplying factor between the links 531, 542 may be varied by an arrangement 540. The factor is set to a desired value by the movement, over a scale, of a member 543 to which is pivoted a link 541 carrying the pivot common to the links 531, 542. The link 526 is pivoted at 527 on a plate 525 restrained from turning about its pivot 528 by a detent mechanism 533 controlled by a spring 534. For large displacements of the rod 512 the lever 526 engages adjustable stops 549, 550 on the plate 525 so that the latter pivots about the point 528 to transmit larger relative displacements to the link 546 through linkwork 551, 562, 564, 565 provided with a variable multiplying factor by the arrangement 560. Displacement of throttle servomotor 520 proportional to the rate of change of engine speed is provided by an acceleration measuring device 501 servomotor 570 and, for small displacements, the linkwork 572, 586, 591, 602, 604 ... 609, 548, incorporating an arrangement 600 for varying the multiplying factor. For large displacements the link 586 moves the link 606 through the plate 588 and linkwork 611, 622, 624, 625, incorporating an arrangement 620 for varying the multiplying factor. The displacement term corresponding to the absquare of the rate of change of engine speed is provided by a cam 630 operated by a rack 633, on the member 572, and a pinion 632. The cam follower 631 on the lever 634, moves the lever and thence the link 608 through the linkwork 635, 642, 644, 645, incorporating an arrangement 640 for varying the multiplying factor.
Patent GB-857118-A (GB)
Title: Improvements relating to the production of hydrogen fluoride
IPC: C01B7/19
Filed: 1958-09-05
Abstract: HF and SiO2 are produced by reacting SiF4 with water in the vapour phase to form HF, SiO2, and unreacted SiF4, separating SiO2, reacting the HF and SiF4 with NaF to form NaHF2 and Na2SiF6, decomposing the NaHF2 by heating to below 500 DEG C. to recover HF, and decomposing the Na2SiF6 by heating to 500-700 DEG C. to recover SiF4.  SiF4 with, or without, admixed HF is obtained by acid decomposition of silicon- and fluorine-containing raw materials, e.g. siliceous fluorspar, or by thermal decomposition of fluosilicates.  The SiF4 is hydrolysed by steam at above 500 DEG C. in the presence of air, or by combustion in a flame, as described in Specification 793,054, where SiO2 of size 5-50 mm  is obtained by reacting SiF4, combustible gas and free oxygen-containing gas in a flame liberating 0.1 X 10-5-1.3 X 10-5 b.t.u.-1. The SiO2 is separated from the gases by a series of cyclones, or on a filter.  The remaining gases may be absorbed on solid NaF at above the dew point but below 200 DEG C. to yield a mixture of NaHF2 and Na2SiF6.  Alternatively, the gases may be cooled below 100 DEG C. to form a condensate solution of HF and H2SiF6. Solid NaF may be added to the solution to form a mixture of NaHF2 and Na2SiF6, or the stoichiometric amount of NaF may be added to react with the H2SiF6 and the precipitated Na2SiF6 filtered off, and the stoichiometric amount of NaF added to the remaining solution to precipitate NaHF2.  The mixture of NaHF2 and Na2SiF6 is heated in an electric, or gas heated rotary, furnace first at 350 DEG C. to form HF from the NaHF2, and then heated to 600 DEG C. to form SiF4 from Na2SiF6.  Where the NaHF2 and Na2SiF6 are formed separately, the separated precipitates are heated at the same temperatures for decomposition.  The SiF4 is recycled to the vapour phase hydrolysis and the NaF from the decomposition is returned to the absorption stage.  Specifications 258,313, 438,782, 675,341 and 728,095 also are referred to.

A cheque blank for use in the GIRO system has an area which is printed with a radiation sensitive printing ink and which when exposed to irradiation by an electron beam changes in colour. The cheque blank is provided with a rectangular panel which is imprinted with the readiation sensitive printing ink composed of a halogen containing polymer, e.g. polyvinyl chloride or polyvinylidene chloride and an acid sensitive dye such as di-ethyl yellow. To authenticate the cheque blank it is exposed to a scanning beam of electrons from an accelerator operating at 150-300 kV, the pattern of scanning being designed to produce wavy patterns that are found on bank notes. Interposed between the beam and the cheque blank is a mask bearing a date in characters which are opaque to the radiation. The radiation area shows a pattern of wavy lines in red surrounding the date in yellow. The authenticated cheque is voided by exposure to ultra-violet light light from a lamp for a predetermined period of time to cause a breakdown of the polymer and to release enough hydrogen chloride to turn the whole panel red, which is protected against ordinary ultra-violet light by a layer opaque to it.

Title: Improvements in process of polymerizing vinyl derivatives
IPC: C08F2/36
Filed: 1929-09-23
Abstract: 319,588. Du Pont de Nemours & Co., E. I., (Assignees of Lawson, W. E.). Sept. 22, 1928, [Convention date]. Polymerized vinyl esters; polymerized styrene and vinyl naphthalene. - Vinyl esters such as vinyl acetate, chloride, chloracetate or mixtures of them or other vinyl derivatives such as styrene and vinyl naphthalene, are polymerized in liquid phase by forcing a solution of the vinyl compound and a catalyst continuously through a heated reaction tube. The resulting solution is then forced through a cooling-tube, the rate of flow being controlled by the rate of drawing off the products through a needle valve. The reaction mixture may be forced from a storage cylinder through the apparatus by means of compressed gas such as nitrogen or by a pump. In the examples (1) a solution of vinyl chloride in chlorbenzene, containing some benzoyl peroxide is forced at 200 lb. pressure through a tin-lined reaction tube at 118‹ C., the polymer so produced being soluble in toluene; (2) a mixture of ethyl acetate, vinyl chloride, vinyl acetate, and benzoyl peroxide is forced through a lead-lined steel tube at 120‹ C.; (3) a similar mixture is used at 500 lb. pressure; (4) a solution of styrene in benzene with benzoyl peroxide is forced through a lead-lined tube at 117‹ C. and 200 lb. pressure; a solution of styrene in ethyl-benzene is treated with ozone for 5 hours and then polymerized as in the preceding example. Other catalysts such as sodium bisulphite, and other solvents such as acetone and toluene may be used. Specification 319,587 is referred to.

Abstract: 383,023. Laundry presses. WILKIE, W., 75, Rimsdal Street, Mile-end, Glasgow. Oct. 19, 1931, No. 28960. [Class 138 (ii).] In a laundry press, the main valve G is connected to a relief valve and a cylinder p and is provided with an operating rod A provided with handles B, C and pivoted to a rod D which is pivoted at El to the cover F of the main valve G. A screw H on the lever D contacts with a button I positioned in the cover F and resting on a diaphragm J which is held in position on the top of a ring K by a screw K<1>. A second diaphragm L is attached to the lower part of the ring K and rests on a button Q supported by a valve P which is itself supported by a collar R on a fluted spindle R<1> which passes through an opening R2 into a lower chamber S, another valve T being attached to its lower end and held on to a seat S<1> by a spring U. An aperture N in the chamber M is connected by a pipe u to an aperture h in a relief valve, an aperture O<2> is open to the atmosphere, and inlet and outlet ports W, X are provided in the valve G. The port X is connected by a pipe s to the port t in the cylinder p. The relief valve, Fig. 3, comprises a valve h held on to its seating by a spring K and provided with a fluted valve rod f which passes through an opening in the valve body a and is engaged by a screw f<1> carried by a lever f pivoted to a bracket m secured to the body a. The aperture e is connected by a pipe r to the port q in the cylinder p. On depressing the lever D with both hands, the valve P is closed and the valve T opened, air passing through the tube t into the cylinder p. When the piston v has travelled in the cylinder p to the port q, air passes by pipe r to the relief valve and thence by pipe u to the port N in the valve G and deflects the diaphragms J, L keeping the valve P closed and valve T open. When the pressure in the cylinder p is to be released, the lever l on the relief valve is depressed and air escapes through the fluted ports of the rod f thus relieving the pressure on the diaphragm J, L, the spring U then closing the valve T. The air from the cylinder p now passes to the atmosphere by the tube s, port X, the fluted parts of the rod R<1> and the port O<2>. When the pressing operation has finished, the air pressure is released by pressing down the lever l, thus opening the valve h. The pressure on the diaphragm J, L is thus released, the valve P opened and the valve T closed.
