Title: Service request priority resolver and encoder
IPC: G06F13/26
Filed: 1968-07-16
Abstract: 1,225,048. Priority resolver and encoder BURROUGHS CORP. 16 July, 1968 [24 Aug., 1967], No. 33875/68. Headings G4A and G4H. A priority resolver and encoder directly generates a binary number corresponding to the highest priority channel bearing a signal among a plurality of channels of pre-assigned priority. An arrangement for handling signals on 512 channels in three levels of logic is disclosed. At the first level (Fig. 1A), the input channels or conductors which are arranged in descending order of priority from left to right are divided into eight blocks 11-18 of 64 channels each and the channels of each block are divided into eight groups of eight channels each. Each group of eight channels is connected to a circuit 1 (Fig. 2, not shown) for generating signals indicating whether ANY or NONE of the channels bear signals and for generating the three least significant digits of the binary number corresponding to the highest priority signal into that circuit. The ANY and NONE signals from each circuit, are applied to a logic circuit 11-3 (Fig. 3, not shown) which generates SEL signals to selectively open that one of gating circuits 11-4 (Fig. 4, not shown) corresponding to the group of channels having the highest priority signal. The outputs of the selected gating circuit 11-4 are fed to a further gating circuit 11-5 (Fig. 5, not shown) to which are also applied strobe and clock signals together with further select signals SEL from the second level of logic. The outputs of the circuits 11-5 in each block 11-18 are connected in parallel and only that block 11-18 corresponding to the highest priority channel signal is selected to transmit output signals representing the least three significant bits of the required binary number. The second level of logic (Figs. 1B and 1C) comprising only a single block 40 deals with the ANY and NONE signals from the first level in a similar manner to the above to generate the middle three bits of the required binary number. The third level of logic (Fig. 1C) comprising only a single circuit 1 and a single gating circuit 50-5 deals with the ANY and NONE signals from the second level and generates the three most significant bits of the required binary number together with signals indicating either NO REQUEST or ANY REQUEST. The invention may be utilized in an electric communications system or a data processing system in which latter case the channels are respectively connected to input/output devices of the system, the high transfer rate devices being assigned correspondingly high priorities, and the 9-bit binary output number is inserted into a look-ahead register.

Abstract: 477,116. Stereoscopic photography. OKOLICSANYI, F. VON. Dec. 11, 1936, No. 34059. Convention date, Dec. 12, 1935. [Classes 97 (i) and 98 (ii)] To produce stereoscopic photographic or kinematographic pictures a lenticular screen is placed before the film for each exposure, the camera is moved horizontally at right-angles to the optical axis of the lens simultaneously with the motion of a vertical slit across the lens. The width of the slit is such that an image thereof formed on the film by one of the cylindrical lenses is one-tenth of the width of the lens. The picture is developed and is viewed through a lenticular screen when a stereoscopic effect is produced or, if the observer moves relative to the picture, the latter appears to be in motion. For kinematographic pictures, one image frame is exposed for each lateral motion of the camera. The images are projected on to a screen in front of which is a system of glass rods each having a width twenty times that of the projected image of one slit image, the rods being immersed in a liquid having a refractive index slightly different from that of the glass rods.
