IPC: A61F2/58
Filed: 1916-05-22
Abstract: 106,522. Sheehan, C. A. May 22, 1916. Limbs, artificial.-An artificial arm, for use more particularly in cases where the shoulder is disarticulated, is operated by a single cord attached to a member engaging the thigh of the wearer. The cord serves to raise and bend the arm, to turn and bend the wrist, and to bring the fingers and thumb to the gripping position. The arm is carried by a foundation of leather or wood in two parts a, a<1> hinged together and attached to a waistcoat, and comprises an upper arm member l and lower arm members m, n formed of steel tubes or aluminium rods. The member l is pivoted to a steel dome d<2> carried by a plate d pivoted at d' to a guide f attached to the member a. The hand, Figs. 1 and 5, is pivoted at j<1> to an arch-shaped member o, which is pivoted at o<1> to the end of the forearm member n, and the hand comprises pivoted finger and thumb normally held extended by springs v. The hand and fingers are made of sheet metal. The arm and hand are operated by means of a cord i attached to cords r from the fingers and thumb and passing over a pulley i' at the elbow and through a loop t<1> to the upper end of a rod h. The rod h is fitted at its lower end with a saddle h<2> to engage the thigh, and at its upper end with a hook h<1> adapted to engage one of a series of ratchet teeth g on the member a<1>, whereby the arm may be held in the raised position. The rod h works in a tubular guide h<3> on the member a<1> and is limited in its downward movement by a strap h<4>. The hand tends to turn about the pivot o<1> when the arm is raised, and is returned to the normal position when the arm is dropped, by a cord u attached at one end of the wrist pivot j<1> and passing under the member n through a loop t<2> to the pivot d' of the arm. The hand may be fitted with a hook w, Fig. 1, and the operating-cords r of the third and fourth fingers may be loose, so that these fingers are later than the others in coming into action. The arm may be covered by hollow casings constructed of latticed cane bound with leather and pivoted together at the elbow. Fig. 6 shows a modification generally similar to that shown in Fig. 1, but in which the arm is pivoted to a rod d which is pivoted at d<1> to the foundation member a. According to the Provisional Specification, the hand. in bending, may co-operate with a rod moving towards the palm of the hand to grip an article, and the rod may be formed at its end with a hook upon which articles may be carried. Specification 16720/10, [Class 52 (iii), Tables &c.], is referred to.

Title: Adhesive and allied processes and products obtained thereby
IPC: B29C65/48
Filed: 1963-02-22
Abstract: Synthetic resins &c. rendered adherent to liquids such as aqueous or other printing inks, by subjecting their surfaces, directly or through an unaffected medium, to friction applied for example by a hand-held pad or a rotating felt, silicone or rubber pad, disc or roller.  Resinous &c. materials specified are p-olefines such as polythene and polyproylene, styrene, vinyl and vinylidene polymers and copolymers, acrylic and methacrylic polymers, polyamides, polyesters, polyurethanes, regenerated cellulose, cellulose esters, and incompletely cured phenol-, urea- and melamineformaldehyde resins.  The friction may be applied through a layer of P.T.F.E. or regenerated cellulose, subsequently removed, and the materials may be supported on a plane base or on a patterned or embossed base the pattern of which is then repeated in their surface adhesion to printing inks &c. Friction may be enhanced by the use of water, aqueous liquids, a chlorinated hydrocarbon, or solid particles e.g. of carbon, sulphur, talc or iron or other metal filings.  The friction may also be applied under water, or accompanied by the application of an electrostatic field or H.F. heating.  Examples include the frictioning of polythene, p.v.c. and polypropylene followed by the application of water- or alcohol-based acrylic ink or dye which, after drying, is found to be firmly adhered at the parts frictioned.
Patent GB-646772-A (GB)
Title: Improvements in and relating to the preparation of powdered metals and or metal carbides for extrusion
IPC: B22F1/14
Filed: 1944-04-20
Abstract: The powdered metal or carbide is vibrated to break up nodules and distribute particles evenly, and simultaneously the gas released by the vibration is removed, as by suction.  Then the powder is compacted and impregnated with a liquid plasticizing medium or with a liquid medium which, in combination with a material initially added to the powder, forms a plasticizing medium when the compacted impregnated powder is heated.  The vibration may be effected by filling the powder into a container and placing the container on a vibrating platform of the type known as a vibrating conveyer, (see U.S.A. Specification 2,187,717).  The compaction may be effected by a different type of vibration, e.g. a simple up and down motion such as is produced by an air hammer or vertical electrical vibrator, under the influence of a weight placed on top of the powder.  The compacted material may be stored, before impregnation, in an atmosphere of hydrogen to prevent oxidation.  The liquid plasticizing medium may be rosin dissolved in ether, paraffin in carbon tetrachloride, shellac in alcohol, or cellulose in amyl acetate.  The powder may contain starch, in which case the compacted powder is impregnated with a water glycerine solution, the powder being then heated to cook the starch; the water glycerine solution in combination with the cooked starch plasticizes the material.  After plasticizing the material may be extruded, dried and sintered.

Title: Improvements in methods and apparatus for manufacturing filamentous mats and to filamentous mats
IPC: B29C48/05
Filed: 1965-02-22
Abstract: 1,103,752. Winding filamentary mats. AMERICAN AIR FILTER CO. Inc. 22 Feb., 1965 [24 Feb., 1964], No. 7492/65. Addition to 994,604. Heading B8G. [Also in Divisions D1 and B5] The method of forming a filamentous mat of the parent Specification in which filaments 8 are wound on a former 2 by orbiting the ends of the former about an axis, i.e. that of shafts 16, which intersects an axis passing through the ends of the former and about which the former is rotated, is modified by also winding about the former a strip 56 which separates adjacent layers of the filaments. The two motions of the former, i.e. the orbiting motion which also causes the former to rotate one turn for each orbiting revolution, and the independent additional rotary movement, causes the filaments 8 to be laid -down in a sinuous path on the former to form a network of overlapping filaments. Preferably the amount of revolution of the former about its own axis, that is the algebraic sum of the orbital and the additional rotary movement, in one orbital revolution only differs slightly from 1, say equal to 1<SP>1</SP>/ 2500 , that is 2500 orbital revolutions are required to form one layer of the filamentous mat on the former composed of 2501 (or 2499) filaments or bundles of filaments spread along the former. Strip 56 is supplied from roll 54 mounted to orbit with former 2 so that the strip is continuously unwound at the same rate as the filamentorous layer is formed to cover the formed layer and allow the new layer to be formed on the strip. The former may be circular, elliptical, or rectangular in cross-section. The filamentous mat together with strip 56 may be unwound from the former to obtain one long mat, or alternatively the assembled layers may be cut through whilst on the former to obtain a plurality of mats. Strip 56, which may be paper or a preformed filamentous latticework strip, may be used as a reinforcing layer for the mat by having an adhesive face, or strip 56 may in fact comprise two superimposed strips-one a reinforcing strip and the other a layer separating strip. The filaments, which may be glass filaments from furnace 10, may have resin applied thereto before winding, or during winding on the former. The matting has one or both side edges trimmed before being removed from the former.

Abstract: 313,647. Shaw, R. March 15, 1928, Ellipsographs. - Relates to a device for cutting ellipses from flat plates or sheets particularly of glass, and in which the cutting-edge of the cutter is held in a direction which is always tangential to the ellipse at the point being cut. According to the invention, a known type of apparatus is provided with an additional four-link mechanism for automatically keeping the cutter in the right direction. The apparatus is shown diagrammatically in Fig. 1 and comprises a carrier bar C which has a cutter holder P and two points A, B which are constrained to move along axes X-X and Y-Y, respectively, at right angles to one another. A member D which slides along the. bar C forms one member of the four link frame, the other members E, F, G being pivoted to one another as shown. The link E is constrained to move in a circular path H with its centre at O, the intersection of the axes X and Y. The link G is one arm of a bell-crank lever, the other arm L being pivoted to a rod J that slides through a hole in the cutter-holder, which is pivoted to the carrier bar C. The length of the links is so chosen that when the carrier bar is moved, the link parallelogram keeps the cutter edge tangential to the ellipse which it describes. Figs. 2 and 3 show in plan and elevation, respectively, a known type of apparatus to which the invention is applied. An eccentric 8, adjustably secured to a shaft 14, engages the parallel sides 12 of a fixed framing, so that its centre A is free to move along the axis X-X.
