Abstract: A HIGH SPEED CMOS COMPARATOR CIRCUIT                         Abstract A high speed comparator comprising an operational amplifier and two inverter portions is provided.  The output voltage of the operational amplifier biases a control transistor coupled to the first inverter portion which is coupled to the operational amplifier in a closed loop. A stable reference voltage is coupled to an input of the operational amplifier and forces the switch point of the first inverter to be at the reference voltage.  If the second inverter portion comprises transistors having the gate dimensions thereof sized the same as the transistors of the first inverter portion, the switch point of the second inverter is also at the reference voltage.  The switch point of the fast comparator has thereby been isolated from process and temperature variations.

Abstract: AN EXPLOSIVE CHARGE-CONTAINING NUT          Abstract of the disclosure Certain types of T-joints having a two-part housing applicable to a pipe contain a member adapted to cut a hole in the pipe, when acted upon by an explosive charge. The intention is to provide a branch conduit from the pipe. The explosive charge is contained in a nut attachable to the housing and is ignited by a percussion cap. A favourable action and a simple manner of production is obtained if the bottom portion of the nut is provided with three con-centric recesses, one smaller than the preceeding one. The first recess holds the charge, the second recess holds a breech member for the percussion cap, and the third recess holds an anvil for firing the cap.

Abstract: ABSTRACT OF THE DISCLOSURE       Earth moving, ground leveling and land planing apparatus having a substantially rectangular frame which is pivotally attached at the back end thereof to a support member containing ground engaging wheels. A cutting blade is disposed laterally between the bottom sides of the frame and a bucket having an open front end with the forward edge of the floor of the bucket mounted at its lower forward edge to the frame adjacent to the trailing edge of said blade. A blade support member extends from the back end of the frame to the forward end thereof substantially along the longitudinal axis of the frame. A downwardly extending projection from the blade support member is integrally attached as by welding to the cutting blade substantially intermediate the cutting width of the blade. The support intermediate the ends of the blade prevents the blade, which has a width of at least about 10 feet, from undersirable deflection of the blade due to the weight of the load of dirt or to forces exerted on the blade from the ground.

Abstract: ABSTRACT OF THE DISCLOSURE     An automatic cooling adjustment system for the forehearth of a glass furnace which enables the mini-mization of the amount of energy used in the fore-hearth.  The system is utilized in a forehearth wherein a continually activated and adjustable cooling wind apparatus operates in conjunction with an electric or fuel fired heating system which con-trols or maintains the glass within a desired tem-perature range and at a predetermined temperature gradient range over the length of the forehearth. An automatic circuit is provided to adjust the amount of cooling wind and to maintain it at whatever level is required in order to minimize the opposing heating energy required.  The system includes a timer which enables small automatic cooling wind adjustements during a first, relatively short time period and which enables temperature stabilization in the forehearth during a second, relatively long time period.  The cycle of small adjustments is repeated as necessary to keep the heating system within pre-set energy limits.

Abstract: NON-OBSTRUCTIVE THERMODYNAMIC FLOW METER       ABSTRACT OF THE DISCLOSURE     A non-obstructive thermodynamic flow meter is disclosed which mounts substantially flush with the inside wall of a pipe and uses thermal techniques to measure the rate of flow of the fluid passing through the pipe.  Two resistance temperature detectors are mounted flush with the inside wall of the pipe and are utilized as sensors.  These two sensors are connected into a bridge circuit with a heater heating one of the two of them.  The bridge circuit is balanced with no fluid flowing in the pipe.  As fluid flow increases the heated sensor cools and changes resistance to unbalance the bridge circuit. The unbalance voltage across the bridge circuit is amplified and causes more power to be applied to the heater to rebalance the bridge circuit.  The amount of power applied to the heater indicates the rate of flow of fluid through the pipe and is detected and used to provide an output indicating the flow rate.  The correlation between the power applied to the heater and flow rate depends on fluid temperature.  Fluid temperature is measured either by a separate sensor or by the non-heated sensor in the bridge circuit.

Abstract: ABSTRACT OF THE DISCLOSURE          A fabric having a novel lock-stitch construction is made on a stitch-through type machine equipped with a single knitting thread guide bar and comprises a flexible substrate such as a layer of textile yarn filling elements, a plurality of warp elements laid on the substrate in the longitudinal or warpwise direction, and knitting thread forming a multiplicity of warpwise stitches in a lock-stitch configuration.  The knitting thread lock-stitch configuration comprises a sequence of three-needle atlas stitch courses on a given knitting thread wale to bind together into an integrated structure the substrate and warp elements, to secure the substrate and warp elements against relative displacement, and to stabilize the fabric against running or lifting off of the warp elements from the fabric surface.  As a result of the knitting thread lock stitch configuration, the fabric exhibits an aesthetically pleasing appearance corresponding to the loft imparted to the warp elements by virtue of the non-binding of the warp elements by the chain stitch components of the knitting thread network.

Abstract: THERMAL FUSE     Abstract of the Disclosure A fuse for responding to external temperatures to interrupt an electrical circuit, for example for interrupting a telephone battery feed in response to the temperature of a battery feed resistor, comprises a substrate carrying a pair of electrodes defining a gap between them.  A fuse link, for example a gold strip, extends across the gap to interconnect the electrodes electrically.  A film of solder overlies the fuse link and overlaps at least partly at least one of the electrodes. The fuse link is soluble in the molten solder so when the temperature of the solder paste exceeds its melting point, it melts, dissolves the fuse link, and retreats from the gap to sever the electrical connection between the electrodes. The fuse and a resistor whose temperature is to be detected, may be provided on a single substrate.     - i -

Abstract: REMOTE TERMINAL FOR USE WITH CENTRAL                 DICTATION APPARATUS                  ABSTRACT OF THE DISCLOSURE         A remote terminal for connection to telephone lines to enable an operator thereas to communicate with dictation apparatus.  The remote terminal includes a power supply which receives the DC power normally applied to the telephone line to derive energizing power therefrom for powering the terminal.  An audio coupling circuit couples audio frequency signals to and from the telephone lines and is selectively connected to a handset by which the operator may transmit and receive speech signals over the telephone lines, or to a headset by which the operator may receive dictated information from the dictation apparatus.  Function control switches, such as foot-pedal switches, are selectively operable to control the dictation apparatus, and a mode selector serves to select either a telephone operating mode for the remote terminal, whereby the function control switches are rendered inoperative, or a dictate/transcribe operating mode for the remote terminal, whereby the function control switches are rendered operative.  A processor, such as a microprocessor, powered by the power supply, is responsive to the mode selector and to the function control switches for controlling the operating mode of the remote terminal and for enabling the remote terminal to communicate with the dictation apparatus.
