Abstract: Abstract of the Disclosure The suitability of a transmission path (16 or 18) for transmission of digital data is monitored by trans-mitting a test signal over the transmission path. The test  signal  is  composed  of  a  succession  of video signal  lines  each  including a horizontal sync pulse and a pattern of digital 1's and 0's at a predeter-mined frequency and occurring on each line at the same data positions relative to the horizontal sync pulse.          The patterns  comprise  a reference pattern of alter-nating 1's and 0's and test pattern of 1's and 0's at random or in a sequence known to be disruptive to the transmission path. The test signal is received and is displayed on a waveform monitor (28) with the refer-ence pattern and the test pattern interleaved with the complement of the reference pattern and complement of the test pattern, so that the four patterns are super-imposed and enclose a generally eye-shaped area.

Abstract: ABSTRACT              UNITARY PLATE ELECTRODE  The unitary electrode (10) comprises a porous sheet of fiberglass resin phase (12) the strands (14) of which contain a coating (16) of conductive tin oxide. The lower portion of the sheet contains layer (18) of resin and the upper layer (20) contains lead dioxide forming a positive active electrode on an electrolyte-impervious layer.  The strands (14) form a continuous conduction path through both layers (16, 18).  Tin oxide is prevented from reduction by coating the sur-face of the plate facing the negative electrode with a conductive, impervious layer resistant to reduction such as a thin film (130) of lead or graphite filled resin adhered to the plate with a layer (31) of conductive adhesive.  The plate (10) can be formed by casting a molten resin from kettle (60) onto a sheet of glass wool (56) overlying a sheet of lead foil and then apply-ing positive active paste from hopper (64) into the upper layer (68).  The plate  can also be formed by passing an assembly of a sheet (80) of resin, a sheet (86) of sintered glass and a sheet (90) of lead be-tween the nip (92) of heated rollers (93, 95) and then filling lead oxide into the pores (116) of the upper layer (118).

Abstract: TITLE OF THE INVENTION TUBE EXPANSION PROCESS            ABSTRACT OF THE DISCLOSURE     A process for the controlled expansion of a conduit against the walls of a circumscribing structure is disclosed herein. The process generally comprises the steps of applying a radially expansive force to the conduit, while monitoring a variable associated with the elastic and plastic properties of the particular conduit being expanded in order to determine a final swaging force which will complete the expansion process. The process of the invention is particularly useful in eliminating the clearance between heat exchanger tubes and baffle plates in a nuclear reactor, and in sleeving operations wherein an internally inserted sleeve is plastically deformed against a heat exchanger tube in order to affect an interference joint therebetween.

Abstract: ABSTRACT            SELF REGULATED ACTUATOR            A self-regulated actuator is disclosed having a shape-memory element which is heated preferably by passing electrical current therethrough and having a reset mechanism including a circuit-breaking mechanism.  The shape memory element provides the force to retract the actuator when heated.  The reset mechanism utilizes a spring-biased latch plunger that resets the actuator as soon as it has retracted a specific distance.  The reset mechanism also acts as a circuit breaking mechanism to electrically interrupt current heating the shape-memory element.  The reset mechanism provides near instant reset time and overcomes the longer wait period otherwise associated with the natural cooling of the shape memory element.  The reset mechanism prevents overheating of the shape-memory element and precludes the necessity for additional hardware to interrupt the circuit after actuation is completed.  Also discussed is a self-protection means that protects the shape-memory element from deliberate and accidental overloads and to accommodate the extra motion required for high-cycle design life.

Abstract: ABSTRACT A transformerless drive circuit for operation of a switch mode regulator includes a turn-on circuit and a turn-off circuit coupled to a control terminal of the switch, respectively, for inducing a state of conduction in the switch and for terminating the state of conduction. The switch is, in the preferred embodiment, a P-channel DMOS field-effect transistor (FET) with a source electrode connected to the positive voltage terminal of a power supply, and with the drain terminal connected to load circuitry of the regulator.  The gate electrode serves as the control terminal.  The regulator includes a sensor of output voltage and circuitry for providing a pulse-width modulated control signal for designating the average amount of current to be passed by the switch.  The turn-on circuit and the turn-off circuit share a common diode which operates alternately for conduction or turn-off.  The turn-off circuit includes a bootstrap capacitor for momentarily powering the circuit for saturating a transistor therein, the rela-tively low saturation voltage being impressed at the control terminal for rapid turn-off.  The drawing of current by the turn-on circuit pulls a gate-voltage away from the power line for rapid turn-on.

Abstract: RATCHET PULLER FOR NAILS AND STAPLES                 ABSTRACT OF THE INVENTION            A ratchet puller for nails and staples in accordance with this invention includes a ratchet lever or bar having a ratchet mechanism at one end with a tool mounting stud extending from the ratchet mechanism, and a pry tool for mounting thereon which includes a claw portion having a wedge slot for receiving the shanks of nails, spikes and similar items to be pried out of a piece of wood or other structure they are embedded in and which may include a pointed tip or stab to hook under the bight portion of staples and similar items for prying out of whatever they are embedded in.  The pry tool includes a peripheral bearing surface to serve as a fulcrum when the ratchet lever or bar is moved causing the wedge slot, or pointed tip, of the tool to lift the nail shank, or staple as the case may be.               BACKGROUND OF THE INVENTION            This invention relates to the field of tools and other devices for pulling nails, spikes, tacks, staples and the like from pieces of wood or other structures in which they are embed-ded.           The prior art includes a variety of tools for this purpose of many difference shapes and designs to grip the head o a nail or spike, or its shank and to then pry it out by leverage of the handle or bar.  One problem that already known devices have not been able to solve effectively is that of reaching into a small space to grasp the head or shank of a nail for pulling it out wherein there is not enough room to move the handle or bar portion of the tool sufficiently to pry the nail out.  The ratchet bar and pry tool mounted thereon in accordance with this inven-tion is able to raise the nail in small step by step increments by reciprocating the ratchet handle or bar back and forth what-ever short distances the small space allows.

Abstract: ABSTRACT OF THE DISCLOSURE:     This invention relates to the design of mar-shalling yard with upgrade speed control system.  The principal difference between  this yard and the conven-tional marshalling yard with downgrade only profile is described hereunder.  Unlike the already known yard in which many speed control devices are installed on a down-grade to consume excess energy of cuts, the yard in the invention has an hump height designed by taking operating conditions of moderate runners as a base and is provided with at least one upgrade speed control unit consisting of one upgrade section and a necessary number of boosters and retarders on the downgrade profile.  This upgrade control unit could convert excess energy of cuts into potential energy.  The invention could raise hump operating capacity of marshalling yard at a considerably reduced cost.
