Abstract: ABSTRACT OF THE DISCLOSURE            A multple vessel cascade gas enrichment adsorber is provided herein.  A first stage adsorption vessel is provided with a primary gas inflow means, a primary gas outflow means, and a mass of a suitable adsor-bent material in the vessel disposed between the primary gas inflow means and the primary gas outflow means.  At least one subsequent stage adsorp-tion vessel is provided in cascading interconnection with the first stage adsorption vessel through an associated interstage loop line, each such subsequent stage adsorption vessel being provided with a first gas inlet means, a first gas outlet means and a mass of a suitable adsorption material disposed between the first inlet means and the first outlet means. The first outlet means which is associated with the subsequent stage adsorp-tion vessel farthest downstream from the first stage adsorption vessel is provided with an outlet back pressure regulator and non-return valve.  Each such associated interstage loop line includes a back pressure regulator and valve therein.  Secondary gas outlet means lead to secondary gas outlet lines from each of the first stage adsorption vessel and the subsequent stage adsorption vessel, each such secondary gas outlet means including a plurality of vertically spaced-apart, horizontally extending collector means, disposed within each such first stage adsorption vessel and such subsequent stage adsorption vessel.   Each such collector means is pro-vided with a plurality of dispersed gas inlet ports.  Diaphragm valves are associated with each such collector means.  Means actuate the diaphragm valves for alternate cyclical operation for a production period, defined as the period wherein the diaphragm valves are closed (to provide a long adsorption path from the primary inflow means to the first outlet means), and an evacuation period, defined as the period wherein the diaphragm valves are opened (to provide a short desorption path through the secondary outlet means).  The individual volumetric size of the subsequent stage vessel or vessels must be smaller than the volumetric size of the first stage vessel.  The cascading of the adsorbers significantly decreases the time required for regeneration by increasing the tolerance for residual adsorbate on the major portion of the adsorbent.  Despite the cyclic nature of the process, the flow of product, e.g., oxygen, is continuous.

Abstract: PATENT APPLICATION         of LOUIS R. FALCE       for METHOD OF FABRICATING  A DISPENSER CATHODE                         Abstract A dispenser cathode is fabricated by covering a reservoir of electron emitting material with a perforated metal foil having an appropriate pattern of pore-sized apertures thereon for providing uniform electron emission from the cathode surface. The electron emitting material is in the form of a pellet of barium oxide impregnated with a wax or resinous material to minimize chemical reduction of the barium oxide in air. The impregnated barium oxide pellet is sandwiched between the apertured foil and a support structure to which the foil is welded. During tube bake-out or subsequently during cathode activation, the wax or resinous material evaporates and barium oxide migrates through the apertures to cover the surface of the foil in a uniform manner.  The barium oxide pellet is obtained from the carbonate and is wax impregnated prior to assembly into the cathode.  Thus no carbonate is present at the tube bake out or cathode activa-tion stages, thereby avoiding the carburization of electron emitting metal surfaces.

Abstract: ABSTRACT OF THE DISCLOSURE                A patch module assembly consists of a two piece frame structure, which provides three parallel jack receptacles entering the frame through one end for receiving patch cord wand.  The sides of the frame are closed by printed circuit boards which are electrically connected through plug connectors through the other end wall.  The circuit boards support T-Bar*type switch wafers whose normally closed switches are in series in the various printed circuits between connectors. The printed circuitry also connects spring contacts at one of the wand support receptacles to one side of one of the switches.  Another wand sup-port receptacle has spring contacts connected to the opposite side of the switches.  A third wand support receptacle has spring contacts connected to either one side or the other of the switches.  The contacts of the respective receptacles mate with contacts on an insertable wand, which en-able patch connection to other circuits.  Placing the wand in the first or second receptacle causes an actuator to disconnect the series switches after which one side or the other of each series switch is connected to some remote circuit.  The third receptacle does not disconnect the series switches but makes a connection to the line through each series switch to serve as a voltage monitoring device, or the like.  In the first two receptacles, the nose of the wand engages a different cam surface of the same actuation lever, which moves against an actuation plunger of the series switch wafer opening the normally closed contacts. The wand is a split cylindrical structure of hollow form, internal portions of which provide two oppositely directed contact assemblies.  The contact assemblies can be preassembled and prewired before assembling the wands. In the assembly of the two halves of the cylindrical wand, insulator bases opposed to each other urge the contacts outwardly through holes along diametrically opposite sides of the wand positioned to engage the respective spring fingers.          * Trade Mark

Abstract: Abstract An SSB-FDM modulator derived from a complex band-pass digital filter bank and by a filter breakdown process comprises a discrete Fourier transform (DFT) processor capable of giving phase offsets to complex output signals thereof.  In a broader sense, DFT includes inverse DFT (IDFT).  The processor is called an offset discrete Fourier transform (ODFT) processor and is sup-plied with real baseband sample sequences.  The phase offset complex output signals are frequency-selected by a complex band-pass digital filter unit operable at a sampling frequency for the baseband sample sequences into a real SSB-FDM signal.  An SSB-FDM demodulator likewise derived comprises a complex band-pass digital filter unit for frequency-selecting a real SSB-FDM signal into complex sample sequences of the respective baseband channels. The complex sample sequences are ODFT'ed into real baseband sample sequences.  For easier processing of signals transmitted between the modulator and demodulator, use is made of at least one dummy baseband channel.  The phase offsets may be pro-vided in the modulator by a post-processor following a conventional DFT pro-cessor and in the demodulator by a pre-processor prior to conventional DFT. If desired, frequency spectra of the sample sequences of a predeterminded one or ones of the baseband channels may be reversed in the modulator prior to digital filtering and in the demodulator after the ODFT.

Abstract: Abstract:      Water soluble crystalline material which has been comminuted in a saturated aqueous solution of the material in the presence of a water-soluble crystal-growth inhibitor having a hydrophobic portion and a hydrophilic portion in its molecular structure is mixed with a deflocculant which inhibits the interaction of the hydrophobic molecular portions whenever the comminuted solid is suspended in water.  The viscosity of aqueous suspensions of comminuted solid is thereby stabilised.      The invention is especially beneficial in the preparation of aqueous suspensions of finely comminuted ammonium nitrate for use in slurry blasting explosives.      With crystal-growth inhibitors such as water-soluble polysaccharide derivatives, long chain aliphatic amines, polyacrylic acids, sulphonated nuclear aromatic compounds, sulphonated dyes or sulphonated polymers the preferred deflocculant, which should be different from the crystal-growth inhibitor, may include water-soluble poly-saccharide derivatives, polyacrylic acid, polyvinyl pyrrolindone, sodium lignosulphonate and/or a salt of a condensate of naphthalene sulphonic acid with formaldehyde.

Abstract: FLYING INSECT KILLER & LIGHT FIXTURE INCORPORATING SAME      ABSTRACT A light fixture incorporating a motorized insect exterminator includes a frame, a light source, and a motor mounted on the frame.  A drive shaft of the motor is connected to an end of a clear and pliable plastic impeller.  A translucent plate is mounted between the light source and plastic impeller.  The impeller is rotated between 2,000 and 3,600 RPM's by the motor, sweeping out a circular area in the proximity of the plate on the opposite side from the light source.  Flying insects, attracted to the light source, fly toward the light source, slow down to land on the plate, fly through the circular area at a relatively slow speed, and are fatally hit by the rapidly revolving impeller.  The impeller is flexible and light enough and rotates at a slow enough speed to avoid injury to or cutting a finger which comes in contact with the rotating impeller.  In one embodiment, a series of opaque strips are juxtaposed to translucent or transparent strips to provide dark landing sites for the insects.

Abstract: Abstract of Disclosure One form of the timer is designed to be mounted over and behind a conventional wall switch cover plate and includes a two position timer condition-setting arm, a rotatable and depressible time setting dial knob and an in-dicator on the front of the cover plate.  When the arm is moved to a timer-on position, the indicator flashes to indi-cate that timer programming is needed.  This may be achieved in real time over the first twenty-four hours after a 30 minute play period by depressing the knob acting as an on and off power switch control push button to turn the light circuit on and off in a normal manner.  Fast manual program-ming is achieved by rotating the knob to various time set-tings and depressing the knob to set ON or OFF markers in timer memory.  A full twenty-four hour programming is corn-pleted by either completing a full rotation of the knob over the full twenty-four hour time settings, with at least on ON and one OFF derpession, or by a similar pair of knob depressions without such a full rotation, OFF markers then being automatically set by the timer to complete the timer programming.  The indicator comes steady-on to indicate that the timer is fully programmed and in an automatic mode of operation. The automatic operation is temporarily overrid-den by depression of the knob or permanently overridden by a simple distinctive speed or time duration depression of the knob.
