Abstract: ABSTRACT      In a rotary hammer drill in which the tool is driven in rotation by rotating the cylinder 21 housing a driver piston 30 and a striker 32, the hammering effect is rendered inoperative by providing in the well of the barrel an aperture 35 which is axially positioned so as to vent the space between the driver and striker to atmosphere.  A sleeve 37 is mounted on the external surface of the barrel and is axially movable to blank off the aperture 35 or to place it in communication with the ambient atmosphere.

Abstract: A CONNECTOR ASSEMBLY WITH VISUAL, TACTILE AND AUDIBLE INDICATOR            ABSTRACT The present invention relates to the field of connector assemblies for electrical conductors, fiber optics, and the like. Prior art connectors have attempted to provide visual, aural, or tactile indications of the mating condition of connector assemblies, but have not incorporated all three indications in a single assembly and the visual indicators have provided only limited viewing angle. The connector assembly of the present invention employs a radially-movable indicator which extends outside of and substantially entirely about the periphery of the connector to provide substan-tially omni-directional visible indication and tactile indication of mating condition.  An audible indicating mechanism is also included which provides a self-locking feature for the connector assembly.  The indicating means are operatively associated with a coupling member for drawing the connector assembly into mating engagement.

Abstract: Abstract A multifrequency tone receiver is disclosed for detecting simultaneous tone signals in a sampled digital signal.  The tone receiver includes a microprogrammed sequence controller, a time-multiplexed digital filter and a signal processing microcomputer.  For each sample of the digital signal, the sequence controller is pro-grammed to time multiplex the digital filter for perform-ing three cascaded second order filtering operations (two bandpass filter operations and one low pass filter opera-tion) for each of six tone signals to provide correspond ing energy estimates and one additional filtering operation to provide a total energy estimate.  The signal processing microcomputer processes a number of sets of the seven energy estimates and provides an indication when a multifrequency tone pair has been detected.  The digital filter, when enabled by a filter start signal from the sequence controller, asynchronously performs a single multiplication like filtering operation to implement each second-order filter, and provides a filter done signal upon completion of the filtering operation. Full-wave rectifying capability is provided during low pass filtering operations by logically complementing the digital filter input signal.  Limit cycles may be sup-pressed in the digital filter output signal by rounding the output signal and clamping positive and negative overflows to the largest allowable positive and negative signals, respectively.  The tone receiver may be advan-tageously utilized in a PCM communication system for detecting multifrequency tone signalling used for dialing and supervisory control.  Moreover, the inventive tone receiver may be adapted to receive many different types of tone signalling simply by changing firmware there-within,

Abstract: METHOD FOR ASSEMBLING AN ELECTROCHEMICAL CELL     ABSTRACT OF THE DISCLOSURE           A method for assembling a primary electrochemical cell including a carbon cathode structure.  The carbon cathode structure is assembled by arranging a selected number of individual annular-shaped porous carbon elements, each having an opening extending therethrough, together with an elongated, hollow, cylindrical metal current collector tube so that the carbon elements are in a stacked array and the tube is loosely disposed within and along the openings in the array of carbon elements.  The current collector tube is an expandable member and is initially in a non-expanded state and loosely surrounded by the stacked array of carbon elements.  A porous separator and an anode structure are then placed around the aforementioned assembly of the carbon elements and the current collector tube, and the resultant assembly, representing a battery stack, is placed within an elongated housing of an electro-chemical cell.  A tool is then employed to permanently expand the current collector tube outwardly so that the tube makes direct physical contact with the array of carbon elements.  An electrolyte solution is placed within the cell in contact with the battery stack and the hollow opening of the tube.  The electrolyte solution permeates the carbon elements directly and also by way of a large number of small holes formed in the tube, causing the porous carbon elements to be permeated with the electrolyte solution and expand outwardly.  The expansion of the carbon elements causes constituent particles thereof to fill the openings in the current collector tube thereby permanently locking the carbon elements to the current collector tube.

Abstract: Abstract of the Disclosure A video display system is disclosed.  Video signals are converted from analog to digital format. Portions of the signal are selected for display and transmitted to the display elements.  A high speed quality display is obtained by utilizing transmission circuits which can operate in real time at a rate suf-ficiently high to keep up with the incoming video signal. This permits the system to utilize more video information than it has previously been possible to use.  An addi-tional feature of the invention is the ability to simu-late a travelling sign display by causing a message to appear to move across the scoreboard.
