Title: Solid electrolytic capacitors and method of manufacture
IPC: H01G9/052
Filed: 1964-01-30
Abstract: A method of manufacturing a capacitor comprises: subjecting particles of an anodizable metal, or pellets prepared therefrom, to an elevated temperature, e.g. above 2200  DEG C., at a reduced atmospheric pressure, or in a flowing inert gas at or below atmospheric pressure; pressing and sintering the particles, or the powder obtained by pulverizing the pellets to form a porous body; producing a dielectric film on the exposed surfaces of the body by anodizing; producing an oxide layer over the dielectric film; and providing a conductive layer over the oxide layer.  Suitable anodizable metals are tantalum, aluminium, tungsten, niobium, hafnium, titanium and zirconium.  As described, tantalum pellets are treated at a temperature between 2400 DEG C. and 2600  DEG C. and are anodized prior to pulverization to increase their oxygen content to 0.18% by weight.

Title: Improvements in or relating to permutation or combination locks
IPC: E05B37/02
Filed: 1921-02-02
Abstract: 178,599. Ratcliffe, W. M., and Sambidge, W. Feb. 2, 1921. Locks, permutation; keyholes, obstructing.-In a permutation lock, the combination is changed by disengaging geared discs by a further turn of a bolt-operating member, which is concentric with the disc-setting dials. Setting-dials 1, 2, and 3, having letters or figures on their peripheries, are connected through their coaxial spindles, to corresponding toothed wheels 8, 9, 10, gearing with a second set of toothed wheels 11, 12, 13, pivoted on a plate 15. These wheels are gapped at 23, Fig. 19. Coaxial with the setting dials is a dial or member 17 which has attached to its hollow spindle, the followers 19 and 24. When the setting-discs are arranged in a given combination, the gapped discs are in position to receive a stud 22, Fig. 7, on the bolt plate, and the member 17 car. ba turned, its follower 19 pulling back the bolt-plate 20, which slides under the plate 15 by reason of the slot 20<xx> in which works the pivot pin carrying the gapped discs. To change the combination, the member 17 is turned until the follower 24 enters the notches 15x and 20<xxx> in the plate 15 and bolt plate 20 respectively, these having been aligned by first withdrawing the bolt. The follower 24 then moves the plate 15 and the bolt 20 to the left, carrying with them the gapped discs, as shown in Fig. 13. The toothed discs are then disengaged and the setting-dials 1, 2, 3, may be turned to any new combination. The toothed discs are re-engaged by turning back the member 17. In order to avoid turning the member 17 too far when operating the bolt and so disengaging the toothed wheels, this member has a slot 30 in which work two pins 31, 32 fixed to the casing. A hand-operated radially sliding stop 33 may be employed to limit the degree of rotation of the member 17, and to allow full rotation when desired. The bolt of the, lock may be constructed to cover the keyhole of a safe or door lock.

Each railway rail is mounted in a shallow recess 3 across the sleeper 1 and any thrust against the side walls of the recess 3 is distributed by vertical plate-like members 5, 6, provided at each wall of the recess 3, rigidly connected and spaced apart a distance equal to the width of the rail foot; the plate-like members are held against movement longitudinally of the rail. The vertical plates 5, 6 may be formed by one of the flanges of angle sections the horizontal flanges of which sections are accommodated in grooves in the face of the recess 3 or, as shown in Fig. 12, by strips resting on the face of or, Fig. 15 (not shown), in grooves in the faces of the recess 3. The plates 5, 6 are joined by members 15 downwardly turned so as to engage the sloping sides of the sleeper 1 or alternatively by angle pieces or strips to prevent movement in the axial direction of the track. In a further modification, Fig. 13 (not shown), the ends of the plates are downwardly turned so as to engage the sloping sides of the sleeper 1. Webs may also be provided on the base-portion of the angle sections to engage notches in the face of the recess 3. A resilient pad is usually inserted between the rail 4 and the sleeper 1 and grooves 8, Fig. 6, in the face of the recess 3 at an angle to or parallel with the rail axis prevent movement of the pad 7. The pad 7 may be provided with heel portions 23, Fig. 16, or with ribs or nubs which bear on the horizontal flanges when such flanges are disposed below the level of the face of the recess 3.

The rail 4 is held in position by clamps 16 or 17 the outer lugs of which engage a support member 20 contained in a recess or merely the recess 21 formed in the sleeper 1. Rotation of the clamps 16, 17 is prevented by the recess 21 or member 20 or by extending the plates 5, 6 above the height of the rail foot. The device may be used with reinforced concrete, wooden sleepers or sleepers of any other material.
