Abstract: A calculating device and a mechanical method of calculating win, place and show odds for events such as horse races having pari-mutuel wagering systems. The apparatus includes a base member and a pair of slideable members laterally displaceable relative to the base member. A transparent cursor having a hairline located thereon is also laterally displaceable relative to the base member and to the slideable members. In an alternative embodiment, the members and the cursor are rotationally displaceable relative to the base member. The device is arranged so that indicia on a first scale which represent the amount in a wager pool of interest may be positioned relative to a second scale so that the hairline on the cursor may be adjusted to the amount bet on a horse of interest. The win odds of the horse of interest may be directly read beneath the cursor on a third scale and those odds may be calculated in terms of dollars returnable for a given bet on a fourth scale.

Abstract: A display device for decorative or advertising purposes capable of apparently converting a black and white image into a partially or entirely colored image when visible light is passed through a pair of adjacent translucent sheets. The first sheet contains an image which appears from an observation point forward of the first sheet as a black and white image in the absence of the visible light passing through the first sheet. The second translucent sheet located closely adjacent the first sheet contains at least a portion of the image on the first sheet and is at least partially colored so that when light passes through the pair of sheets, a colored image which is the optical combination of said first image and said second image is apparent from the observation point. In a preferred embodiment, the black and white sheet is made from a paper having photographic properties and is photographically negative.

Abstract: In a magnetic recording/reproducing apparatus having a plurality of push-buttons for directing changeover of tape drive modes, a simple and compact mechanism for effecting mode changeover including an idler, a reciprocating member, sliding actuating bars and an alternative-selection mechanism, all operated by the motive force from a motor-driven capstan. The idler is mounted for movement into and out of contact with a wheel mounted for rotation with the capstan and the reciprocating member moves responsive to the movement of the idler. The idler can be carried to a position spaced from the capstan wheel by the movement of the reciprocating member. Actuating bars, one associated with each push-button, are engaged and disengaged with the reciprocating member by an alternative selection mechanism.

Abstract: A transmitter for determining the speed of rotation and the angular position of a rotating member, such as a shaft, in which a coding disc is driven synchronously with the shaft and has a series of circularly distributed light and dark areas which cooperate with two sections of alternating light and dark areas formed by a coding segment which is fixed relative to the disc. The pitch of the light and dark areas of the coding segment is equal to the pitch of the light and dark areas of the coding disc, respectively, and the light and dark areas of one section of the coding segment are staggered relative to the light and dark areas of the other section thereof. A light is passed towards the coding disc and the coding segment and at least one photosensitive receiver is in the path of the light passing through the light areas for generating an output signal.

Abstract: A telephone paging system includes a central interconnect station responsive to phoned information for automatically transmitting the caller's verbal message to a designated portable paging receiver. The central station instructs the caller by means of a prerecorded message to provide a brief voice message preceded by touch tone or rotary dial digits identifying the receiver to be paged. The paging code digits and message are both tape-recorded by the central station. If the transmitter is free, the recorded paging code is automatically played back through a decoding circuit responsive to rotary dial clicks as well as touch tones. The output of the decoding circuit keys a radio transmitter which transmits a corresponding code followed by the recorded voice message. The central station employs a plurality of recorders. If one recorder is in operation, an incoming call is transferred to the next recorder. Recordings awaiting access to the transmitter are taken in a predetermined order.

Abstract: An audio amplifier in which an output stage is coupled by a driver stage to an input stage which includes two antiphased sources of alternating current. The output stage includes two pentode vacuum tubes each having a cathode, a plate and a screen grid located between the cathode and the plate.
