Title: Improvements in and relating to Animating Means for a Figure Toy
IPC: A63H3/48
Filed: 1966-08-09
Abstract: 1,176,168. Animating for toy. MATTEL Inc. 9 Aug., 1966 [22 April, 1966], No. 35601/ 66. Heading A6S. The head of a doll has a flexible plastic face, which has simulated nose, eyebrow, eye and mouth portions, and the head contains means for animating the mouth thus producing sad, neutral or smiling expressions and optionally eyebrow animating means and actuating means for producing noise from the doll and tears from the eyes, the latter actuation being delayed until the actuation of eyebrow and mouth has begun. Figures 6 and 8 illustrate the animating means described below. The mouth portion 40 is animated by movement of a U-shaped clip 288 having a bight portion embedded in the lower lip. On mouth animation, the lower lip is forced slightly upwardly and outwardly, and other U-shaped clips 308 pull the. corners of. the mouth down. Simultaneously the eyebrow animating means 196 is operated by the same actuator 134 pulling a portion of the eyebrow down over the eye, simulating a frowning expression. A conventional bellows-type noise maker 326 is used to imitate a crying sound when the animating means is actuated. In addition, as the actuator means nears the end of its animating stroke, a squeeze bulb 242 containing-water is depressed by the eyebrow animating means 196 causing water to flow through the conduit means 248 to a duct 474 provided in fluid communication with each eye. Flow restricting means 478 is provided in the ducts in order that the water oozes out of the eyes thus simulating tears. The actuator 134 and hence other animating means are actuated by movement of an arm of the doll. Movement of the arm insert 142 is transmitted into a reciprocating movement of the arm 134, through the rotation of part 148 which is connected to actuator 134 by the pitman 162. The noise maker 326 is not operated until the eyebrows 36 and mouth 40 have been animated to achieve the sad expression. This is accomplished by retaining the spring 330 in a compressed condition by engaging a rib 396 on the actuator guide 126 by a noisemaker actuator 398.

Abstract: 1,059,570. Panoramic photography and projection. N.I. ANDERSON. Sept.10, 1963 sept.10, 1962], No.35692/63. Headings G2A and G2E. A system of cine or still panoramic photography in which the camera 14 photographs the virtual image of scene 10 formed by convex mirror 12. In projecting from the film so prepared, a convex mirror directs the projection beam on to a concave screen. The ratio of height to width of the projected image is exaggerated to give a "wide-angle" effect by the use of an ellipsoidal mirror 12 with an anamorphic camera lens, or the mirror 12 may be spherical and a variable anamorphic lens used. In each case a projection system may be used which is a duplicate of the photographic system used. A second mirror 30, which may be plane or convex or concave is used in Fig. 9 to allow the camera 14 to face the scene 10; a similar projection system is used. When distortion has been corrected in printing the positive film, projection is possible directly on to the concave screen without intervening mirrors, or if distortion persists, a variable anamorphic projection lens is used.

Abstract: 156,104. Neumeyer Akt.-Ges., F., (formerly Bayerische H³ttenwerk F. Neumeyer Akt.-Ges.). Dec. 27, 1919, [Convention date]. No Patent granted (SeaLing fee not paid). Turning-gear. - The invention consists in a compact arrangement of the gearing in a starting-device of the kind in which an electric starting - motor drives the engine shaft through planetary gearing at reduced speed, and is driven as a generator at engine speed when the engine starts. Planet pinions 3 on a carrier 8, 9 geared to the engine are in mesh with teeth 1 on the motor shaft 2 and with the internally-toothed flange 4 of a disc 15. During starting, the gear 4 is held stationary by pawls 19 pivoted at 18 between the disc 15 and a second disc 28 and engaging ratchet teeth 17 on the fixed casing 11. When the engine starts, the pawls 19 are Automatically disengaged by the centrifugal action of weights 23, which also bring pawls 21 into engagement with a ratchet member 16 having teeth 32 in mesh with the teeth 1 on the motor shaft 2, so that the gearing is locked and rotates as a whole. According to the invention, the ratchet member 16 is within the toothed ring 17 on the casing in order to obtain a compact arrangement. The weights 23 may be integral with the pawls 21 and are pivoted at 20 upon the discs 15, 28 and acted upon by springs 25. Teeth 26 on the ends of the weights engage the toothed hubs 27 of the pawls 19. The movement in unison of all the pawls 19, 21 is ensured by a loose toothed ring 31 in mesh with the toothed hubs 27. If the engine should start backwards, the slowing-down before reversal causes the weights 23 to withdraw the pawls 21 and re-engage the pawls 19. The gearing is enclosed by a casing 12.
