IPC: A61F2/58
Abstract: 131,236. Henning, F. C. Feb. 14. 1919. Limbs, artificial.-Comprises a construction of mechanism for operating the fingers and rotating the wrists of artificial hands. The parts of the three-joint fingers and the two-joint thumb are pivoted together, and the back surface of the hand, and are operated by crank linkages connected to a common rock-shaft 18. The rocking of the shaft 18 in a clockwise direction against the action of springs 19 causes successive bending of the sections of each finger and thumb until the whole hand is closed to its limiting position. For rocking the shaft 18, a roller 22 is moved down an inclined guideway 23 in the hand by exerting an axial pull on the rod' 25 through the medium of a harness or like cord 29. This cord can be locked in any position by a screw clamp on the exterior of the arm. The rod 25 is made in two parts capable of relative rotation, and is mounted centrally in the wrist so that the latter can be turned without affecting the fingeroperating mechanism. For turning the wrist by the flexing of the elbow, the ends of a cord 31 pass from a lever 35 on the elbow joint, through a guide 34 at the back of the wrist, and thence round a circumferential groove 30' in the hand. The cord is anchored at one point to the hand by being passed into the hollow interior in the form of a loop which is clamped by the member 32.

Abstract: 598,971. Making composite pipes. ARNOLD, J. C. (Standard Oil Development Co.). May 25, 1945, No. 13188. [Classes 83 (i) and 83 (ii)] Casting composite articles; casting pocesses.-A method of making conduits for corrosive fluids consisting of an inner rigid corrosion - resistant pipe separated from an outer pressure - resistant casing by a corrosion - resistant material, comprises mounting the inner pipe concentrically within the outer casing by clamping means at each end so as to form an annular chamber, one end of which is closed by one of the clamping means and pouring into the chamber a liquid corrosion-resistant material and allowing it to solidify. An inner lining of structural carbon 10 is held concentrically within an outer steel tube 50 by means of upper and lower clamping members 30, 20, connected by a rod 40. The inner surface of the steel tube is previously cleaned and tinned and the whole structure is heated by gas burners 70, or electrically, and molten lead is poured into the annular space 60. The lower clamping member 20 is formed with an annular recess 62 adapted to close the lower end of the annular space and to form a radial flange at the end of the cast insert. The upper clamping member 30 has radial lugs bearing against the outer casing but leaving the annular space partly uncovered. After pouring, the heating is cut-off progressively so that the lead cools from the bottom to the top, additional lead being poured in to make up for shrinkage. After casting, the upper end of the conduit is cropped to remove dross, screw-threaded and a pipe flange is attached, the face of the flange being covered with lead by burning or bonding and this covering is burned on to the annular lead layer of the conduit. The ends of the carbon lining are cemented to the lead lining. Instead of lead, porcelain in liquid form may be poured into the annular space and allowed to solidify, and in that case, an inner rigid tube of porcelain could be used instead of carbon. Specification 586,245, [Group XXVIII], is referred to.

Abstract: 498,815. Delivering material from hoppers. GASCOIGNE, G. H., and KNOX, J. R. May 13, 1937, No. 13481. [Class 78 (i)] [Also in Group XVIII] A cattle-feeding apparatus cornprises a supply hopper and a weigh pan carried on a tiltable balance bar, arranged so that the material in the supply hopper is released by a manual actuation that jolts the supply hopper to ensure delivery, and the delivery is maintained by sustained manual control against the force of a spring until the weigh pan has collected a charge visually determined by observing the tilting of the balance bar, the pan with its charge being then tipped or inverted by manual actuation. As shown in Fig. 2, the hopper 1 containing the cattle food is pivoted on a bar 2 and may be rocked thereon by means of a pull rod 4 so as to displace the open bottom of the hopper from a fixed closure plate 3. The movement, which is limited by a stop plate 5 and collar 7, jolts the hopper and ensures a flow of food. A spring 6 returns the hopper when the pull rod is released. The food falls into a pan 8 secured to a rod 8a slidable, by means of a handle 13, within a tubular beam 9 mounted on trunnions 10. When the beam rocks (limited by a stirrup 12) the operator releases the pull rod 4 to stop the delivery of food and pushes the rod 8a free of a bayonet-joint connection with the tubular beam. The pan may then be inverted to discharge the food. A spring 13a restores the bayonet-joint connection. An adjustable weight 11 determines the weight required to tilt the beam. In a modification, Fig. 6, instead of rocking the hopper, a sack constituting the lower part of the hopper may be provided with a pivoted jaw 17 operated by the pull rod 4 and spring 6 in order to start and stop the delivery of food.
