Abstract: ABSTRACT OF THE DISCLOSURE a fixed, hollow, cylindrical, open ended electrically conductive cathode concentrically surrounds a hollow, cylindrical, electrically conductive anode. The anode is fixed upon an electrically conductive axle so as to allow the anode and axle to rotate inside the cathode.  Electrically non-conductive brushes are mounted on the anode and rotate therewith, sweeping over the radially inner surface of the cathode.  A water inlet housing at one end of the cathode and a water exhaust housing at the other end of the cathode cooperate to divert a stream of water (in which salt has been dissolved) between the anode and the cathode, the housing also supporting the conductive axle and allowing it to rotate. An electric motor rotates the axle.

Abstract: DIFFERENTIAL PRESSURE SWITCH            Abstract of the Disclosure A differential pressure module is secured in switching relation to the actuating plunger of an electrical switching mechanism.  Comprising the differential pressure module are two piston/cylinder assemblies connected together in back-to-back configuration by secured cross members forming a floating yoke.  Each of the assemblies includes a diaphragm in communica-tion with a separate oppositely directed fluid inlet and through which a force differential effective from the separate forces acting in opposition to each other is applied via the yoke against the switch actuator.  A cast body intervening between the assemblies defines the fluid inlets while maintaining the pressure of each isolated from the other.

Abstract: SPIRAL WOUND CAN HAVING DISCRETE LABEL              AND REINFORCING ELEMENTS                Abstract of the Disclosure A spiral wound can is described in which the body of the can is made up of a relatively heavy fiberboard base or body layer lined within by an oil and moisture impermeable barrier formed from a laminate of aluminum foil and paper.  The heavy base layer includes a helically extending separation line or butt joint bonded together by the liner and a reinforcing tensile element in the form of a reinforcing strip.  A discrete label covers the reinforcing strip and the body stock and is bonded to the body stock by at least two broken of unbroken lines of adhesive on opposite sides of the reinforcing strip.  A circum-ferentially extending collar cut is made through both the label and the reinforcing strip to facilitate their removal.  In one form of the invention, the reinforcing strip is bonded more strongly to the label than to the body and is removed then the label is removed.  In another form of the invention, the label is not bonded to the reinforcing strip and is removed first.          The reinforcing strip is in the second form provided with an adhesive free area under one corner which defines a lifting tab allowing it to be lifted manually and removed.

Abstract: SPRINKLER HEAD                   Abstract of the Disclosure An improved sprinkler head for an automatic fire extin-guishing system.  The sprinkler head comprises a frame having a discharge orifice and a deflector spaced from the orifice.  A cap normally encloses the discharge orifice and is held in place by a lever assembly.  The lever assembly  includes a lever having a pair of spaced side flanges and a tube extends between the flanges. Located within the central portion of the tube is a fusible element and balls are positioned in the ends of the tube on either side of the fusible element and engaged with sockets in the respective flanges.  In the event the element is subjected to an elevated  temperature, it will melt causing the balls to move inwardly of the tube and thereby releasing the lever assembly to open the discharge orifice.

Title: Composite coalescing filter tube and method of manufacture thereof
Inventor: BERGER L JOSEPH JR
IPC: B01D39/20
Filed: 1976-07-05
Granted: 1981-01-20
Abstract: ABSTRACT OF DISCLOSURE           The specification discloses a novel composite coalescing filter tube and the method of making the same.  In contrast to previous coalescing filters, which had layers of filter material sandwiched between relatively rigid support members, the present invention provides for a completely unitary coalescing filter tube wherein the various layers of the filter are successively vacuum formed one over the other on a forming fixture which is submerged in an appropriate glass fiber slurry mix, with  the various layers being air dried, epoxy dipped, and cured as needed for the particular application.  Since, during the vacuum forming process, glass fibers from one layer will interlock with glass fibers from the previously formed layer, a completely unitary coalescing filter tube is formed, preventing the problems of filter layer separation, chaneling, pressure collapse and vibration damage which have occurred in past coalescing filters.

Abstract: COMPRESSOR BLEED SYSTEM     ABSTRACT OF THE DISCLOSURE    Methods and apparatus for flowing cooling air from the compressor section to the turbine section of a gas turbine engine are disclosed. Cooling air from the compressor is flowed radially inward through the compressor drum cavity and thence axially rearward along the rotor shaft to the turbine. Vortex pressure losses in the drum cavity are diminished to enable effective utilization of a lower pressure, lower temperature cooling air source.  The use of air from the lower pressure, lower temperature source improves the overall engine operating efficiency while maintaining turbine cooling rates which are consonant with durable operation of the engine.

Abstract: A B S T R A C T     The invention concerns a method and apparatus for measuring the wall thickness of tubular members using pulses of ultrasonic energy and measuring the time interval between the echoes from the two surfaces of the wall. A rotating diagonal reflector in combination with a fixed transducer is used to scan the interior of the member with the time between the echo from the inner and outer surfaces of the wall being used as a measure of the wall thickness. Each of the time measurements is assigned to a particular counter to accumulate all measurements of a particular thickness. This provides a profile of the wall thickness of the tubular member.

Abstract: ABSTRACT OF THE DISCLOSURE        A pressure sensitive Silicon chip is indirectly bonded to a Stainless Steel housing of an electronic pressure transmitter through an intermediate holder assembly.  This indirect bonding prevents thermal cracking of the Silicon chip due to the dif-ference in thermal expansion of the Stainless Steel housing and the Silicon chip.  The holder assembly includes a Borosilicate glass tube having the Silicon chip bonded thereto which tube is soldered to a Nickel-Iron alloy holder by a eutectic alloy solder.           In assembly, the Nickel-Iron holder is first brazed to the Stain-less Steel housing at a first temperature greater than the maximum non-destructive temperature of either the chip or the glass tube and the glass tube is then soldered to the Nickel-Iron holder at a lower temperature which will not destroy the chip or the tube holder.

Abstract: METHOD OF AND APPARATUS FOR MODIFYING A VIDEO SIGNAL TO PREVENT UNAUTHORIZED RECORDING AND REPRODUCTION THEREOF                      ABSTRACT OF THE DISCLOSURE           A method of and apparatus for modifying a video signal such that a video picture can be reproduced on a television receiver in response to the modified video signal, but if the modified video signal is transmitted and then recorded on a video signal recorder, an accurate video picture cannot be reproduced if that recorded modified video signal subsequently is played back.  The vertical blanking interval containing one set of equalizing pulses followed by a set of vertical synchronizing pulses followed by another set of equalizing pulses is modified by replacing a portion of the vertical synchronizing pulses and a portion of the set of equal-izing pulses following the vertical synchronizing pulses with simulated equalizing pulses in at least some of the vertical blanking intervals.  The amplitude and frequency of the simulated equalizing pulses are equal to that of the actual equalizing pulses.         In one embodiment, the modified video signal is trans-mitted via, for example, cable or RF transmission.  In another embodiment, the modified video signal is recorded on a master recording medium.  If the master recording medium subsequently is reproduced, the resulting, reproduced modified video signal can be transmitted for video display.  However, if a copy of the master recording medium is made, an accurate video picture cannot be reproduced from subsequent reproduction of the copy medium.                        -i-
