Title: Capacitors
IPC: H01G4/10
Filed: 1964-05-01
Abstract: 1,057,910. Insulators. GLOBE-UNION Inc. May 1, 1964 [June 27, 1963], No. 18130/64. Heading H2C. [Also in Division H1] A capacitor adapted to be secured to or form part of a conductive wall is formed from a nickel member whose surface is oxidized in situ to provide an insulating nickel oxide layer which is then covered with a conductive coating. Such a capacitor may be used as a stand-off or feed through capacitor to enable high frequency signals to be by-passed to the conductive wall. Two capacitors in series may be produced by painting conductive silver coatings, 18, 19 containing a frit such as BiO 3  on the inside and outside of a nickel tube 10 (Fig. 1). The tube is-fired to provide nickel oxide dielectric layers between the nickel and silver layers. A belled portion 12 enables the assembly to be mounted in a panel, while wires carrying high frequency signals may either pass through the tube or be soldered to its inside. Alternatively a nickel rod having a shoulder may be similarly treated (Fig. 5, not shown). In an alternative embodiment (Fig. 7, not shown) a nickel wall is painted with oxygen permeable paint, an aperture drilled through and the arrangement fired. A conductor may then be soldered into the hole. A stand-off capacitor (Fig. 10, not shown) comprises an oxidized silver-coated nickel rod with projections at each end which is crimped into a hole in a metal wall.

Title: Corrected magnesia products and method of making the same
Filed: 1944-09-27
Abstract: Crystalline refractory periclase is produced by intimately mixing magnesium oxide or other magnesia-yielding material with silica which is in a state of sub-division finer than can be obtained mechanically and which, together with any silica present as an impurity in the magnesia does not amount to more than 10 per cent., and heating to sintering temperature.  The magnesia employed may be obtained by precipitation from seawater, by electrostatic precipitation from the flue dust of rotary furnaces used in the calcination of magnesia, or from powdered brucite. The silica is obtained in a state of subdivision approaching colloidal size and preferably of an amorphous character from the fumes resulting from the production of ferrosilicon or from the reoxidation of volatilized silicon produced in the reduction of silica in the presence of carbon or reducing gases.  At least a part of the silica may be incorporated in the seawater prior to precipitation or in the precipitate before final separation of the mother liquor or washing-water; alternatively, it may be incorporated in the partially or completely dried hydroxide either in the dry state or as a slurry respectively.  Specifications 498,183 and 579,098, [both in Group V], and U.S.A. Specifications 792,882 and 2,206,131 are referred to.ALSO:Crystalline, refractory periclase is produced by intimately mixing magnesium oxide or other magnesia-yielding material with silica which is in a state of subdivision finer than can be obtained mechanically and which, together with any silica present as an impurity in the magnesia, does not amount to more than 10 per cent., and heating to sintering temperature.

Abstract: 715,664. Artificial hands. OPUSZENSKI, T. July 23, 1952 [July 24, 1951], No. 18611/52. Class 81(2) An artificial hand is provided with digits formed in three segments, tip, middle and inner, the two latter each comprising two members capable of relative axial movement; each inner and outer member is pivoted to the corresponding member in the adjacent segment and the tip is pivoted to both members in the middle segment. The outer members of the inner segment is mounted on a rotatable knuckle and the inner member is pivoted on a rod spaced therefrom so that relative longitudinal movement occurs between the two members when the knuckle is rotated. In the preferred finger construction, the finger segments are formed of an inner member 36, slidable within a tubular outer member 37. The tip 20 is pivoted to the outer and inner members 28 and 29 of the middle segment, so that pulling on the extension 44 causes the tip to bend, followed by bending of the middle joint. The finger is held in the palm by a knuckle 43 which is rotated by hand-closing mechanism and, preferably, at the same time the extension 44 is drawn back by a shaft engaging a moving cam surface. The thumb is constructed in a similar manner and is geared to the finger actuating mechanism so as to perform a more rapid closing action than the fingers. It has its movement at right angles to that of the fingers. It is preferred that the finger mechanism should be operated by a hydraulic arrangement in which the primary plunger is moved by a cam device driven by an electric motor. This is switched by contacts placed against muscles in the stump so that they are closed when the muscle is flexed. The hand may be automatically turned at the wrist when the elbow is bent, by means of suitably arranged cords.

Abstract: 516,534. Testing physical qualities of materials. SOC. ANON DES HAUTS-FOURNEAUX DE LA CHIERS. June 23, 1938, No. 18699. Convention date, Feb. 18. [Class 106 (ii)] ] Relates to impact means for determining the resistance to fracture of a test piece, and consists in mounting the inertia member for movement along a guide rod to which it is locked at the end of its movement by a number of pawls which can be released to enable the inertia member to resume its normal position relatively to the impact member by means of turning a ring to disengage the pawls against the action of resilient means. A head 1 preferably of duralumin locks the apparatus on the tup and then acts as an impact member. A guide rod 2 fixed to the head is surrounded by a spring 3 attached at one end 4 to the head and at the other to weight 5. When the head is arrested by the impact device 11, the weight extends the spring the pawls 6 slipping over helical threads 8 on the rod 2 and holding the weight in the position reached. By unscrewing the ring 10 the rubber ring 7 is compressed and the pawls retracted to release the weight 5. The travel of the weight is read on the scale 9. The member 11 is of  horse-shoe shape and supported by a steel column (not shown) extending down to the anvil block. The head 1 and rod 2 fit into brackets 12, 13 carried by the tup which brackets pass freely between the arms of the horse-shoe, the head not passing through and being arrested by the member 11. A locking device to prevent rebound of the head comprises bolts 14 actuated by springs 15 associated with double - acting levers 16 having fingers 17. Normally the levers 16 are horizontal and project into the gap of the horse-shoe while the head 1 in its fall engages them to release the bolts 14. The rod 2 at the bottom is secured by a bush 19 over which is looped a copper wire tightened by a screw tightener 20. When impact occurs the mechanical fuse formed by the wire breaks.
