Title: Improvements in or relating to movable-eye mechanisms for dolls and toy figures
IPC: A63H3/40
Filed: 1948-12-31
Abstract: 663,954. Doll's eyes. RETKIN, M., and RETKIN, R. Feb. 6, 1950 [Dec. 31, 1948; Jan. 2, 1950], Nos. 33624/48 and 35/50. Class 132 (iii). A movable - eye mechanism for dolls and the like produces an eye closing effect when the doll is laid down face upwards and an eye moving effect when the doll is given a sideways tilt from an upstanding position. The construction illustrated in Fig. 3 includes a weight 10 carried on a wire loop frame 11 in which a spindle 5 is freely supported at 12, 12. A plate 7, Fig. 1, for example, of plastic, has prominences 8. having eye and eye-lid simulations thereon and is secured to the spindle 5 by wire staples 6. The plate 7, loop 11 and weight 10 thus turn on spindle 5 to cause the eyes to open and close. This action may be produced by laying the doll down face uppermost the weight acting normally as a counterbalance, or by tilting the doll sideways which latter movement causes the weight 10 to slide along the spindle 5 and leg portions 14 of the loop 11 and to ride upon inclined ends 15 of a rigid wire. Another embodiment, Figs. 5-9 (not shown), has separate part-spherical eye elements which are caused to swivel to give the effect of the eyes looking to one side when the doll is tilted sideways.

Title: Improvements in and relating to teleprinter apparatus
IPC: H04L17/18
Filed: 1960-09-30
Abstract: 901,219. Type printing telegraphy. SIEMENS & HALSKE A.G. Sept. 30, 1960 [Sept. 30 1959], No. 33631/60. Class 40 (3). A teleprinter receiving apparatus includes a transmission member which is positioned in accordance with the polarity of the received signal code elements, and a number of resilient fingers mounted on the member which co-operate with storage members to lock each storage member in one of two states according to the position of the transmission member. If a mark pulse is received the receiving magnet 1 attracts its armature 3 and, during the pulse, the transmission member arm 15b moves to the dotted position and back again under the action of cam 9, which rotates once for each character received. Further cams 10, 11 (only two shown), equal in number to the elements in each character, their associated levers 5, 6 sequentially. After a storage lever 6 is raised a spring 21 on the transmission member 15 moves to the right and back similarly to the action of arm 15b, and engages a recess 6b again as lever 6 is lowered. During this action the remaining storage levers are not raised, so the resilient fingers must bend as the transmission member 15 rotates, their free ends being engaged in the recesses in the storage levers. On receipt of a space element armature 3 is no longer attracted so that arm 15b cannot return to its left-ward position, it being prevented by a lip on the end of the released armature 3. The appropriate resilient finger now becomes engaged in the slot in the corresponding storage lever. After the last element of a code character has been stored, adjustment members 22 scan the associated storage levers and are used in known way to effect the printing.
