Title: Improvements in and relating to Artificial Hands.
Inventor: ROWLEY JAMES FRANCIS
IPC: A61F2/58
Filed: 1916-03-08
Abstract: 100,919. Rowley, J. F. Dec. 27, 1915, [Convention date]. Limbs, artificial.-The thumb 40 of an artificial hand is hinged on an axis 35 arranged lengthways of the hand, and is used in conjunction with a spring-mounted forefinger and fixed middle finger, so that in closing the hand for prehension, the thumb slides across the forefinger by pressing it rearwardly, and comes to rest against the middle finger while remaining in contact with the forefinger. The main portion of the thumb is bent to an angle of approximately 45 degrees with the portion adjacent the hinge, and the thumb is closed by pulling a cord 14 which is connected by adjustable guided means 15 to the usual shoulder harness. The cord 14 passes from an anchoring-screw 48 round the grooved end 45 of the thumb and then round a pair of guide-pulleys, shown in Fig. 6, to the hole 55, Fig. 1. A spring coiled round a rod working in the tube 62 maintains the thumb normally in the open position. The recess containing the guide-pulleys and the spring is closed by a removable sliding plate. The thumb may be locked in various positions by a sliding bolt 73 which enters any one of a series of holes 75 in a disk attached to one side of the thumb. In the hand shown, the two middle fingers are fixed, while the little finger is spring-pivoted similarly to the forefinger. The hand is connected by a ball-and-socket or similar joint to a forearm 1, which is hinged to a member strapped to the upper arm and also connected to the shoulder harness by a strap 12.

Abstract: 1,176,924. Directional couplers. WESTERN ELECTRIC CO. Inc. 26 Jan., 1967 [9 Feb., 1966], No. 3935/67. Heading H1W. [Also in Division H3T] In order to produce a difference in the velocities of the odd and even modes propagated in the coupling region of a directional coupler, the coupling region is filled with an inhomogeneous dielectric. The Figure shows a section of a strip-line coupler comprising ground planes 54, 56 and parallel coupled strip-lines 51, 52 deposited on either side of a substrate 53 of, e.g. alumina. The rest of the coupling space is air-filled. The odd and even modes propagate at different velocities since for the odd mode the conductors 51, 52 have opposite polarities and for the even mode they are at the same potential. Thus, the effective dielectric constant is different for the two modes. It is shown in the Specification that the length and other dimensions shown in the Figure may be chosen in relation to the frequency of operation and the dielectric constants of the two media to produce equal division of power between the two output ports of the coupler.

[Class 39 (i)] In a betatron the electrons are first introduced by means of an auxiliary electrostatic field tangentially into a spiral path, and then into the equilibrium circle. The spiral path is produced by means of a rapidly diminishing radial electrostatic auxiliary field superimposed on the normal magnetic guiding field. As shown, deflector plates P direct the electrons along the path a into the spiral path b. The auxiliary radial field is produced by electrostatic plates P<SP>1</SP>, P<SP>11</SP> concentric with the equilibrium circle K. After acceleration the radial field is rapidly increased so that the radius of the equilibrium circle increases until the electrons come under the influence of the ejector plates A. The ejector plates may form continuations 2 of, but electrically insulated from, the plates P<SP>1</SP>, P<SP>11</SP>. The plates Z extend preferably over <SP>1</SP>/ 5 th to <SP>1</SP>/ 10 th of the equilibrium circle, and are most favourably located at a point where the transverse oscillation of electrons about the equilibrium circle in the stabilizing field of force, is a maximum. This point is at a quarter-wavelength of the transverse oscillation from the point of ejection. On ejection the electrons may be led to an anticathode, or to an ionization chamber I. The radial auxiliary field may increase in intensity inwardly or outwardly to provide an axial stabilizing force component.

Abstract: 270,820. Marks, E. C. R., (Parker Rust Proof Co.). Feb. 16, 1926. Dihydrogen orthophosphates of cadmium, iron, manganese, and zinc are prepared by dissolving the metal or metals in a hot concentrated solution of orthophosphoric acid, cooling the solution, and thereby crystallizing out the phosphates. An acid solution of 60-75 per cent con- .,centr,tt,ion is preferred, and it is preferably heated to 100-115‹ C. A solution of the metal having been formed, the liquid is filtered to remove undissolved metal, or other impurities such as carbon which may be present when iron is dissolved. The filtrate is placed in a crystallizing tank and cooled by cold water pipes, crystallization being effected slowly to produce large crystals which are centrifuged and thoroughly and promptly dried under substantially non-oxidizing conditions. The crystals may be heated during drying to produce an anhydrous product, care being taken not to overheat zinc phosphate as the crystals thereof melt at 60‹ C. The manganese and iron phosphates may be prepared together by dissolving ferromanganese. Specification 273,168, [Class 82 (ii), Washing granular &c.], is referred to.
