Filed: 1916-09-20
Abstract: 109,651. Earp, S. Sept. 20, 1916. 'I'eeth, artificial. - Full-contour all-porcelain tooth crowns A for use with vulcanite dentures are formed with a hollowed interior surface tapering outwards from within the incisal edge of the base, to receive the filling C of vulcanite within which is embedded a post B, of suitable metal, secured to the tooth at the apex of the hollow within the incisal edge and extending the full depth of the tooth. The post is secured at its point either by being fired in or by being soldered to a capsule F of platinum, preferably split and previously fixed to the crown, and in the form either of a narrow ring, or extending the whole distance of the interior, Fig. 3, in which case it may have a spiral rib H engaging a corresponding groove on the interior surface of the porcelain. Alternatively, the post is fixed by means of Brills' cement or other material unaffected by vulcanization; it is of any usual form, splayed, headed, hooked, or provided with projections to give a greater surface of engagement for the vulcanite. In the absence of a deep capsule, the interior of the cavity is formed with a spiral groove or serrations E in order to key the vulcanite securely thereto; the post is provided also with inclined stepwise surfaces G to prevent the tooth from being pulled off; and pins, tags, or flanges on the interior of the tooth may additionally secure the vulcanite. Laterally extending passages D give relief to the pressure caused by expansion during vulcanization, and there may be a thickening I over triangular areas at the sides to preserve the natural appearance, more particularly in the case of lower central and upper lateral incisors.

Abstract: 1,188,284. Automatic telephone systems. PLESSEY BTR Ltd. 19 May, 1967 [28 March, 1966], No. 13576/66. Heading H4K. PCM channels of incoming t.d.m. highways are switched to channels of outgoing t.d.m. highways by way of alternately employed storage arrangements worked in parallel. As shown in Fig. 1 the storage arrangements comprise matrices M11, M12, in parallel with matrices M21, M22. The matrices M11 and M21 each have a storage row for each incoming highway such as 10; PCM data in one multiplex cycle being recorded on one matrix and that in the next cycle being recorded on the other matrix and so on. The matrices M12 and M22 each have a storage row for each outgoing highway, such as 11; the matrices being read out to the highways in alternate cycles. While M11 receives and stores PCM data, M21, which contains a record of the data received in the preceding multiplex cycle, is selectively read out to matrix M22 so as to re-arrange the data pending its transmission on the appropriate channels of the outgoing highways in the following cycle. Also at this time the data in M12, which is the re-arranged data from M11 of two multiplex cycles back, is read out to the outgoing highways. A similar arrangement is necessary for transmission in the reverse direction. Instead of being gated in alternate cycles to metrices M11, M21, the incoming highways may be gated in alternate time slots to the equivalent of single columns of such matrices. While the data received by one such smaller store in the preceding time slot is being forwarded to the off-line one of the matrices M12, M22, the other stores the incoming codes in the current time slot. If, on the other hand, the full matrices are preserved for M11, M21, the outgoing matrices M12, M22, may be replaced by smaller stores worked in alternate time slots. The storage arrangements may be magnetic and of the woven plated wire type. Spare matrices may be provided to automatically replace faulty ones.
