Abstract: INPUT GROUPING ARRANGEMENT FOR DATA GATHERING            Abstract of the Disclosure A system is provided for gathering by input groups the counts of busy conditions of 1,024 inputs terminated on 32 input scan cards with each card terminating 32 inputs.          A scan circuit selects the cards one at a time in succession for scanning and causes the inputs of each selected card to be scanned one input at a time in succession so that a single output lead common to all inputs of all cards carries a succession of busy signals according to successively scanned busy inputs.  Each card is provided with a switch settable into one of five positions according to whether the count of busy input conditions of that card is to be accumulated in groups of one, two, eight, 32, or 64 inputs.          A grouping circuit counts the number of successively scanned inputs and provides a succession of group signals corresponding to successive counts of the numbers of inputs specified as successive groups by the switch settings of successively selected cards.  A memory match circuit generates a succession of different seven-digit straight binary codes corresponding to successive group signals.  The 128 possible seven-digit codes (0000000 to 1111111) correspond to the memory access addresses of a 128-section memory circuit.  An addressing circuit generates all 128 codes each time that each single input is scanned; and, the memory access circuitry of the memory circuit is advanced in synchronism with the generation of all 128 codes by the addressing circuit.  The memory match circuit allows each input busy signal to be accumulated as part of an input group busy count at that memory address corresponding to that one of the 128 codes which matches the code generated by the memory match circuit.

Abstract: ABSTRACT OF THE DISCLOSURE    System mode controls for obtaining limited address-ability for supervisor programming operations without dis-turbing a user address key currently contained in a user key register (UKR). The mode controls are provided by bits in a system register called a level status register (LSR), which include an APM bit, and a supervisor state bit.  The largest super-visor addressability is obtained when both the APM and supervisor state bits are set on, which permits execution of a supervisor program which can access user data and programs.  In more detail, each instruction fetch must be in the supervisor key area, identified by a predetermined supervisor key value which is not in the UKR, while each operand of the fetched supervisor instruction is accessed in the user key area identified by the current key in the UKR.  The supervisor is not permitted to access any user area which does not have its key in the UKR.  Thus, the supervisor can be prevented from having addressability over part or all of the main memory.    However, if the APM bit is off while the supervisor bit is on, alI instruction and operand storage accesses can only be made in the supervisor key area, regardless of whether the supervisor key or user key is in the UKR.          Hence no user area is accessible to the supervisor.    But, if the supervisor bit is off, all instruction and operand accesses can only be made in the user area of the key in the UKR.  Hence the supervisor programs cannot execute.

Abstract: ABSTRACT OF THE DISCLOSURE            A slurry separator has a riffled deck that is inclined transversely of the riffles and an exciter that vibrates the deck along a predetermined line of attack axis.  This axis is inclined relative to the deck in a plane that extends longitudinally parallel to the riffles and perpendicular to the deck.  The axis has a vertical component and the exciter is capable of accelerating the deck to a maximum vertical acceleration that is greater than the acceleration of gravity. Slurry fed upon the deck adjacent a feed side thereof flows by gravity down the inclined slope, transversely of the riffles, towards a discharge side of the deck.  High density  solid parti-cles within the slurry tend to settle and these particles are restrained by the riffles from flowing down the in-clined deck, while the remaining slurry, that includes low density solid particles and. a liquid carrier, flows over the riffles.  The deck vibrations convey the high density particles generally parallel to the riffles in a series of rabbit-like hops toward an end of the deck where the particles are discharged.                            -1a--

Abstract: WAYSIDE SIGNALING SYSTEM FOR RAILROAD CAB SIGNALS AND SPEED CONTROL               ABSTRACT OF THE DISCLOSURE    A transmitter and a receiver are located at each junction location between adjoining track sections along a stretch of track for transmitting and receiving cab signal or speed control commands through wire loops laid in a preselected pattern parallel to and between the rails of each section.  Train carried apparatus is selectively reponsive to the speed commands and to the pattern of the wire loops to control the movement of the train in the established direction through the stretch. A distinct directional frequency is transmitted from the selected entrance end of the stretch, when a train movement is desired, and is repeated at each wayside location through the wire loops to the exit end.  The directional frequency reception at each location activates a filter output to selectively enable gating elements to connect the associated transmitter and receiver to the adjoining section loops in accordance with the desired traffic direction.  The speed command transmission is selected in accordance with the advance traffic conditions.  If the immediate advance section is occupied by a train, a restricted speed command is transmitted in the principal loop of the approach section but no command is applied to a second loop at the exit end which causes the train to halt prior to entering the next section.  This prevents the overrun of sections by a following train and the inadvertent reception of a higher speed command intended for the preceding train.
