Title: Improvements in or relating to a method of and apparatus for testing the resistibility of sheet materials to repeated stresses caused by moving loads
IPC: G01N3/30
Filed: 1951-10-16
Abstract: 721,451. Testing physical qualities of paper and like sheet materials. NATRONZELLSTOFF - UND PAPIERFABRIK FRANTSCHACH. Oct. 16, 1951 [July 30, 1951], No. 24135/51. Class 106 (2). The resistibility of sheet materials, particularly sack paper, to stresses caused by repeated loads, is gauged by allowing the material, either in the form of a disc supporting an inertia mass or in the form of a cylinder surrounding an inertia mass, to be repeatedly dropped together with the inertia mass until the material fractures. In Fig. 1, a slide 5 having two clamping rings 3 and 4 is movable on vertical rails 1 and 2. Between the rings 3 and 4 is fixed a hollow cylinder 9. A paper sample 10 under test is gripped between the bottom of the cylinder 9 and a hollow plate 6 held by the ring 4, so that the paper 10 is held along two opposite ends only. The cylinder 9 is then filled with steel balls, 1 mm. in diameter, and is repeatedly lifted by driving means to a height of 14.5 cm. and dropped upon an anvil 16. The number of drops necessary to rupture the paper is registered on a counter as a measure of the dynamic resistivity of the paper. Upon rupture the driving means is automatically switched off by the resulting discharge of the balls into a container 17. In Fig. 5 the sample is formed into a cylinder 21 and fitted with top and bottom caps 22, 20. The bottom cap 20 has a cone-shaped extension within the cylinder so that, when the cylinder is filled with balls and subjected to the dropping tests, the balls will exert a radial pressure upon the wall of the cylinder.

Convention date, Aug. 19, 1929. [Class 114.] A screw propeller is manufactured from a blank by applying a deforming force, by forging rolls, which .is progressively increased from the hub to the tip. The blank A, Fig. 1, has an end-piece 1 whereby it may be held during the process of roller forging. The blank A of aluminium alloy is first heated to a condition wherein it is readily workable, about 820‹ F., and is then subjected to the action of the forging rolls, a number of passes of the rolls being used for successive deformations. In one method the rolls are mounted eccentrically so that the deforming force increases progressively during a rolling pass, when the general propeller shape, Figs. 5 and 6, is obtained. Further shaping may be by the action of forging dies or pressing. The blade is finished by cleaning, trimming and sizing, heated to 960‹ F. for about 12 hours and then quenched and aged for 18 hours at a temperature of 310‹ C. It is stated that under this treatment the wrought metal fibres are set up in flow lines in parallelism with the outer surface. When an aluminium alloy is used, a suitable composition is 94 per cent aluminium, 4¢ per cent copper, ¥ per cent manganese and ¥ per cent silicon.

Title: Process for the preparation of acylation products of phosphorous acid
IPC: C02F5/14
Filed: 1962-06-28
Abstract: An acylation product of phosphorous acid or its alkali metal salts with general formula <FORM:0981252/C1/1> prevents calcium carbonate precipitation in water-softening procedures.ALSO:An acylation product of phosphorous acid containing at least two atoms of phosphorus in the molecule is obtained by reacting a carboxylic acid and water which are present in a total molar proportion of at least 2.5 and preferably at least 3 with one mol. proportion of phosphorus trichloride, the amount of water accounting for up to 1.6 mol. proportions if the acid is monocarboxylic and up to 2.1 mol. proportions if the acid is dicarboxylic and then heating the reaction mixture to between 80 DEG  and 200 DEG  C. In carrying out the reaction phosphorus trichloride is suitably added to a mixture of the acid, e.g. acetic acid, and water while stirring and, if necessary, cooling, but it is also possible to add the acid and water to the trichloride or to add water to a mixture of the acid and the trichloride or the reverse. The process may be carried out in two stages, the first stage being carried out at between 0 DEG  and 80 DEG  C. and the second stage at between 80 DEG  and 200 DEG  C., e.g. between 100 DEG  and 160 DEG  C.  Specified acids are acetic acid, C3-C20 aliphatic monocarboxylic acids, aromatic mono-carboxylic acids e.g. benzoic acid, and C3-C10 aliphatic dicarboxylic acids.  The reaction product may be recovered from the reaction mixture by separating excess acylating agent preferably by distillation under reduced pressure and may be purified by recrystallization or may be treated with water at a temperature above 60 DEG  C.  The acidic product may be converted to the corresponding alkali metal salts, e.g. by neutralization with aqueous or alcoholic caustic alkali solutions.  The products from an acid RCOOH wherein R is alkyl, have the general formula <FORM:0981252/C2/1> Examples are given in which the acids used are acetic, propionic, caproic, lauric, benzoic and adipic acids, respectively.  The acylation products form complexes with polyvalent metal salts and the products or their alkali metal salts may be used for the prevention of calcium carbonate precipitation in the softening of water and also for the stabilization of per compounds. When the products contain long chains they are suitable as wetting agents.

Title: A picking device for shuttleless weaving looms

Filed: 1954-08-27
Abstract: 760,783. Shuttleless looms. MIRA, ZAVODY NA PLETENE A. STAVKOVE ZBOZI, NARODNI PODNIK. Aug. 27, 1954 [Oct. 1, 1953; Oct. 10, 1953], No. 24980/54. Class 142 (2). A weft measuring device for looms in which the weft is inserted by a jet of air or water produced by a nozzle 19, comprises a rotating drum 1 having a smooth portion 1a round which the weft thread is guided by eyelets 13, 17, and a helical groove 4 into which the thread is guided by a claw 6 rotating with the drum. At first, a clamp 18 between the drum and the nozzle is closed, but after one- and-a-half turns (for example) have been wound on, the friction between the thread and the drum is sufficient to pull the thread through a tension device 15 ; the clamp 18 is then opened. A plate 10, rotating slightly faster than the drum, now overtakes the claw 6 and begins to push the thread out of it, thereby causing thread to be drawn back through the nozzle 19 to bring the cut end to the position required for the next pick. When the plate 10 has freed the thread from the claw 6, the nozzle 19 operates to project the thread into the shed, the coils on the drum being pulled off endwise. At first, thread from the supply 14 continues to be wound on the drum, but when most of the coils have been pulled off, the friction between the remaining coils and the drum becomes insufficient to overcome the tension device 15, whereupon winding ceases. The loop of thread between the eyelets 13, 17 slips on the surface 1a of the drum until the clamp 18 closes and the claw 6 initiates another cycle. In another construction, two weft threads pass round, and normally slip on, smooth portions of the drum, additional eyelets on levers operated by pattern mechanism bringing the selected weft into range of the claw to be wound on the drum. Fig. 3 shows a nozzle used for two threads. Fluid pressure in the space 48 tends to open valves 49 by moving them away from the exterior of jets 50 through which the weft threads pass ; electromagnets controlled by pattern mechanism attract armatures 41 to keep one or both valves closed at the required times. Specification 693,751 is referred to.
