Abstract: 394,568. Dental articulators. VOGEL, E. and VOGEL, J., 15, Rue de Lancy, Geneva, Switzerland. Nov. 15, 1932, Nos. 32317 and 32318. Convention dates, Nov. 15, 1931, and Oct. 18, 1932. [Class 81 (ii).] In a dental articulator having one jaw adjustable relative to the other, independently of the articulation movement, by means of a universal joint and a sliding joint, a single member is provided which clamps both joints simultaneously. In the form shown in Figs. 1 and 2 the upper and lower members g, h are articulated at 17 and each comprises a collar i formed in two parts j, l hinged together and adapted to grip undercut projections k on the plaster models. The stem v of the upper collar i is formed with a ball w received in a housing x and pressed against the restricted opening x<1> thereof by a slide 3 bevelled at the end remote from the ball. The slide 3 is engaged by the inclined surface 4 on a rod 5 movable vertically in the housing 3 and passing through an elongated slot 8 in the upper member h of the artioulator. A nut 9 with handwheel 10 bears on the member h and draws the rod 5 upwards so as simultaneously to look both the ball joint and the sliding connexion between the member h and the housing 3. A spring 12 retracts the rod 5 when the nut 9 is released. The pivots 17 of the articulation are carried by a collar 19 rotating about a vertical boss 18 on a platform 15 formed at the end of the lower member g. A pin 23 in the platform 15 works in a slot 24 in the collar 19 to limit the movement, and springs 25 in a recess in the collar bear against a member 27 fitted in a slot 28 in the boss 18 to keep the collar 19 in the normal position. Spring pressed balls 30, Fig. 11, enter recesses in the collar to define the central position. In a modification, Fig. 16, the lower collar i is carried on the arm g by an adjustable slide, and the upper collar is adjustably connected to the arm h as before. The lower arm g comprises divergent arms 48 integral with arms 49 each provided at its free end with a housing 32. The upper arm h comprises divergent arms 34 carrying coaxial bushes 35 connected by a rod 36. Rods 37, fitting within the bushes 35 and bearing against springs 40 therein, enter longitudunal openings 38 in the housings 32 and are connected to balls 39 normally pressed against the bottoms of the bushes by springs within the bushes. This form of articulation permits movement of the upper cast about horizontal and vertical axes and also rectilinear transverse and longitudinal movements.

Title: Method and apparatus for remotely initiating switching operations in telegraph systems
IPC: H04L21/00
Filed: 1952-12-24
Abstract: 732,804. Facsimile telegraphy. SIEMENS & HALSKE AKT.-GES. Dec. 24, 1952 [Dec. 29, 1951], No. 32773/52. Class 40 (3). In telegraph systems, particularly for facsimile telegraphy, in which page-printing is employed and the commencement of the printing of each line is under control of a line synchronizing signal, control signals, distinguishable from the character signals, are transmitted in predetermined phase positions within the line period and are employed at the receiver to initiate a switching or functional operation. At the transmitter, Fig. 1, a shaft. GW driven from a shaft effecting the transmission of the character impulses, completes a full revolution during the transmission of a line of characters, usually 69, and carries a graduated indicating disc ZS. Cams SN1, SN2 on the shaft GW close contacts sn1, sn2 corresponding to predetermined intervals within the line period, and, with the switch VT1 or VT2 closed, effect modulation of the transmitter S by the source WG in a manner similar to the control by the impulse transmitter G. appropriate switch VT1, VT2 may be closed manually, or in the case of transmission by perforated tape, by predetermined sets of perforations. At the receiver, Fig. 2, printing is effected by sequentially operated knife-edge members F1, F2, F3, carried on a chain or band TK driven by wheels Z1, Z2, in combination with a longitudinal knife-edge on a rotating drum, the printing operation being effected by a bar DL urged by printing magnets DM1, DM2 in response to the impulses representing the character. A shaft W2, driven by gearing from the shaft W1, is arranged to make one revolution during the printing of a complete line, and carries cams N1, N2 having projections corresponding to those on the cams SN1, SN2, and operating contacts n1, n2. A magnet A in parallel with the magnets DM1, DM2 closes contacts a1, a2 in response to the received impulses and the reception of a prolonged impulse with contacts n1 or n2 closed, effects the operation of the slow-operating relay K or M. These relays complete respective locking circuits at k1, m1 and at k2, m2 close respectively a circuit for an alarm bell AK or for a magnet KM which may, for example, operate a clutch to connect a shaft to provide rapid feed of the form on which printing is being effected. The control circuit can be broken by switches T1, T2, and in the latter case the control may be effected by perforations in the paper when the latter has been fed to a predetermined position. The control signals may be distinguishable from the character signals by difference of amplitude or of frequency.
