Title: Improvements in and relating to the testing of paper, board, fabric, leather, and other sheet materials
IPC: G01N3/30
Filed: 1925-01-30
Abstract: 248,888. Elmendorf, A., and Marx, R. Jan. 30, 1925. Testing physical qualities of materials. -Comprises a method of determining the strength of paper, board, fabrics, leather, &c. in which a clamped area of the sheet material is subjected to the penetrating action of a falling tool and the amount of energy absorbed in penetration measured. A base plate A, carried on tripod legs B, is provided with a recessed hole C communicating with a spring case D. The specimen of sheet material is clamped to the base-plate by a heavy annular weight E. Rising from the base-plate are two vertical guide members F, bridged at the top, which serve as guides for a carriage G having four arms H and carrying the piercing tool J. The carriage may carry an additional weight K. A hook member L on the carriage engages in the highest position a catch M which may be released by pulling a string P. A spring member R, adapted to be engaged by an extension Q on an arm H, is adapted to be pushed along a scale. In use, the carriage is raised to the highest position and the specimen clamped by the weight E, the member R is adjusted to its zero position on the scale, and the carriage released. After the specimen is pierced, the tool engages the cap X on the spring Y at the same time as the arm Q engages the index B. The amount the index is moved corresponds with the compression of the spring and this depends upon the energy left in the falling weight after piercing the specimen. As, for any particular apparatus, the potential energy of the falling weight at release is constant. the scale may be calibrated in terms of residual energy. The index may take the form of a piston moving in a cylinder of liquid which is pushed up an indicating tube.

Title: Improvements in or relating to ferromagnetic ceramic materials
IPC: C04B35/26
Filed: 1956-01-27
Abstract: 795,269. Magnetic compositions. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Jan. 27, 1956 [Feb. 3, 1955], No. 3730/56. Drawings to Specification. Class 38 (2). To reduce the temperature coefficient of permeability of a manganese zinc ferrite such as forms the subject of Specification 730,703, part of the ferrite oxide used as starting material is replaced by aluminium oxide. In making the composition suitable proportions of ferric, manganese, zinc and aluminium oxides are ground in a ball mill with distilled water, dried, compressed at 5 metric tons/sq. m. and heated at about 1250‹ C. in nitrogen containing 1 per cent of oxygen. Part of the iron oxide is converted into ferrous oxide leaving ferric and aluminium oxides at about 50 mol. per cent of the composition. Permeability and Curie point are lowered and losses raised by addition of aluminium oxide. Losses may be kept down by an addition of 0.01-1.0 per cent by weight of CaO as described in Specification 776,710. In modifications the mixture may be sintered in air, and the mixture of oxides may be obtained by oxidizing a mixture of powdered metals as described in Specification 770,975, [Group XXII]. For most compositions described the temperature coefficient of permeability is reduced over the temperature range -40‹ C. to + 80‹ C. but when they contain more than 30 mol. per cent of MnO the improvement is over the range 0‹ C. to + 80‹ C.

Abstract: 1,162,853. Holograms; electro-photographic deformation images. RANK XEROX Ltd. Jan.18, 1967 [Jan.20, 1966], No.2762/67. Headings G2C and G2H. A method of forming a phase hologram comprises the steps of forming a charge pattern on a deformable thermoplastic layer, said charge pattern corresponding to a holographic interference pattern, and then softening the thermoplastic layer until it deforms in a pattern of ridges and valleys according to the charge pattern. A source of coherent electromagnetic radiation, e. g. a laser 11, is used to form a hologram of an object 14 by the two-beam method, a charged deformable thermoplastic imaging member 16 including a photo-conductive insulator being positioned so that the hologram can be recorded thereon in the form of a pattern of electrostatic charge. The member 16 may then be recharged, depending on its construction, and then replaced in the optical system and exposed to one beam, the other being blocked by a shutter, while the thermoplastic surface is heated. Thus the reconstructed image may be viewed while the thermoplastic imaging member is being developed, so that the development may be stopped when the image is sufficiently developed.

Title: Improvements in or relating to machines suitable for sewing rands to shoes
IPC: D05B73/12
Filed: 1956-01-28
Abstract: 809,335. Sewing machines; well-butting machines. BRITISH UNITED SHOE MACHINERY CO. Ltd., and GERMANY, N.V. Jan. 23, 1957 [Jan. 28, 1956], No. 2833/56. Classes 17(1) and 112 In a machine adapted to sew rands to shoes, an operator-actuable member is connected both to an indicator and to a rand-cutting knife, the arrangement being such that on initial actuation of said member the indicator is brought into proximity with the upper surface of a shoe sole to which a shoe upper and rand are being sewn, and on further actuation of said member, e.g. after a predetermined position of the sole has come beneath the indicator, the knife moves upwardly to sever the rand. The cut may thereby be so positioned that the rear end of the rand neatly abuts the front end. The indicator and the rand-cutting knife are actuated by a lever 28 pivoted on a fixed horizontal pin 8. A triangular plate 10 is also pivoted at its apex on pin 8 and carries at the respective corners of its base opposed screws 16 adapted to limit the swinging of the lever relative to the plate. A spring 22 normally biases the lever against the upper screw 16. The plate is connected by a cable 26 to a rand-cutting knife contained in a housing 48, whereby when the lever is swung downwardly, the knife is moved upwardly to sever a rand R, the latter having been guided through housing 48 to the stitching point. The housing and the parts associated therewith are similar in construction to housing 2 and associated parts as described in Specification 773,895. Housing 48 is carried by an arm 46 fixed to a vertical rod 44 which is in turn carried by an arm 42 fixed to a vertical pivoted rod 34, the latter being acted upon by a torsion spring 36 to bias housing 48 towards the stitching point. A plate 54 pivoted to the upper end of rod 44 carries adjustably an indicator or pointer 58 the free end of which is biased towards the upper surface of the shoe sole by a spring 62. A pin 64 on plate 54 lies in a vertical slot 66 formed in a plate 68 which is connected by a cable 70 to lever 28. Since spring 22 is stronger than spring 62, cable 70 normally raises pointer 58 above the level of the sole. When the stitching of the rand nears completion, lever 30 is depressed to abut the lower screw 16, whereby plate 68 is raised to allow spring 62 to lower pointer 58, and when the end of the latter comes over a predetermined point, e.g. the first stitch at the beginning of the rand, lever 28 is further depressed to actuate the rand-cutting knife.

Title: Improvements in Bomb Throwing Guns or Mortars.
Inventor: POURCEL LEON MARIUS
IPC: F41A1/04
Filed: 1916-03-06
Abstract: 124,523. Pourcel, L. M. Dec. 10, 1915, [Convention date]. Ordnance, pneumatic machine guns. - Relates to bomb-throwing guns, and consists in employing the explosion gases from the cylinder of an internal-combustion engine such as a petrol or alcohol motor to operate one or more guns so as to supply continuously and automatically expel the bombs. Fig. 2 shows one form of gun for continuously discharging bombe such as I, H from a barrel D. The cylinder of a four-stroke-cycle motor (not shown) is connected by a pipe M with a chamber N arranged beneath the gun barrel. When the explosion stroke of the motor occurs, the piston L in the chamber N rises, and through the toggle-levers O, P and plunger K pushes the bomb H into such a position that it is expelled by the passage of the motor gases through a pipe V. When the pressure falls, a spring U returns the parts. In a modification shown in Fig. 4, the loading plunger A<1> is moved forward by the explosion gases acting through passages C, D<1> until a valve E is opened to expel the bomb. The valve is opened by the contact of its collar F<1> with a fixed stop G<1>, and springs H<1> return the parts to the position shown when the pressure falls. Fig. 6 shows a spring-loaded differential valve which is inserted in the pipe M so as to prevent the passage of the gases in the direction of the arrow shown in case of a missfire in the motor cylinder when the pressure is insufficient for discharging the gun. The valve opens against the action of a spring c by the difference of the pressures on the areas 3, 4 when a predetermined pressure is reached, but the valve is kept open by the pressure on the area 4 whilst the pressure falls a predetermined amount. Fig. 7 shows a distributing valve for working two guns from the same motor. A shaft g driven at one-quarter the speed of the motor shaft has cams h, i spaced 180 degrees apart so that, as each explosion of the four-strode motor occurs, the valves j supplying each gun are lifted alternately. Reference has been directed by the Comptroller to Specification 21865/14.
