  • Patent number: 4309839
    Abstract: An amusement device, such as a doll, comprising a body member of a relatively rigid paperboard having a plurality of circular openings, a controlled member on the front of the body adjacent each of said openings, a handle on the rear side of the body, each controlled member having a pair of spaced tabs extending through a corresponding opening in the handle, and a washer having a pair of spaced slots, mounted rearwardly of the handle and receiving the tabs in such a manner that as the handle is moved in a closed path of motion, each of the controlled members is rotated with respect to the body. The controlled members can take the shape of eyes or objects on the front of the doll.

  • Patent number: 4254404
    Abstract: In conjunction with the play of the game of Keno, a combination ticket holder and transmitter-receiver is located at each player's table. Each player's transmitter is coded with a number (e.g., 60,000) of two-tone sequential codes which are transmitted to Keno runners preassigned to specific tables and to a game controller in the Keno lounge. Each player's receiver displays 80 LED digits, numbered 1-80, or other indicatable symbols, and preferably is a super hetradine narrow band receiver to minimize interference from adjacent and co-channel users. Signals are converted from analog to digital when the symbol indicators are connected, and remain displayed until reset for the next game. Each runner has a portable unit with a receiver also which has indicators numbered to identify the players and which preferably also is a super hetradine, dual tone, sequentially coded unit.

  • Patent number: 3983145
    Abstract: Alpha-dihydroxyanthraquinones used as intermediates in the synthesis of many dyestuffs, such as the Alizarin Saphirols (e.g. Color Constitution No. 63000, 63005, 63010, 63011, 63315 and 63610) can be replaced on an equimolar basis by alpha-di(lower alkoxy)anthraquinones. The alpha-di(lower alkoxy) anthraquinones can be converted in a single step, by treatment with oleum, to the corresponding alpha-dihydroxyanthraquinone-beta-disulfonic acids in almost quantitative yield. The corresponding diamine is obtained by dinitrating followed by reduction of the nitro groups. The known intermediate, leuco 1,4,5,8-tetrahydroxyanthraquinone (see C.I. No. 62500) can be obtained either by reduction of the diamine or by reduction of the dinitro compound. In one embodiment, the alpha-di(lower alkoxy)anthraquinone is obtained from dinitroanthraquinone by treatment thereof with methanol and KOH.

  • Patent number: 3970902
    Abstract: An improved miniaturized housing arrangement is disclosed for releasably mounting a chassis, such as a printed circuit board, using the contours and the resiliency of the housing itself to retain and release the board. No special tools are required nor any added hardware. The mounting arrangement captivates only small edge portions of the printed circuit board so as to avoid using valuable space on the board that may be devoted to circuitry and the like. The PC board is also fixedly connected to circuitry provided on a non-rigid base ("flex circuit"). The flex circuit is intended primarily for electrical interconnection but also provides a hinge capability for the board when the latter is released. A strain relief device releasably retains the flex circuit within the housing and prevents damage during hingeing action.
