Abstract: Abstract In the manufacture of low density air laid webs of predominantly ligno-cellulosic material, the method and apparatus for bonding the dry web with binder and compacting the web with a wet, fabric covered surface so as to increase tensile strength and delamination resistance while reducing binder content and cost is described. Wet compaction of the binder laden web enables controlled penetration of the web with a smaller amount of binder than is possible without wet compaction, and also reduces energy consumption in drying due to the use of less binder.

Abstract: Abstract of the Disclosure A  universal document validator in which a document is transported along a path from an entrance toward an exit past an array of a plurality of photo-responsive elements positioned at a predetermined location along the path.  In response to the arrival of the docu-ment at one or more predetermined positions along the path, an area or areas thereof are illuminated and light from the illuminated area is directed over the array of photosensitive elements.  A microprocessor unit extracts from the illuminated array pictures of the areas in terms of the number of elements thereof activated to a pre-determined level and, for each picture, compares this element with a first stored number, corresponding to the minimum number of elements which must be illuminated for an acceptable document and with a second number corres-ponding to the maximum number of elements which should be illuminated for an acceptable document to produce a validating signal when the number of activated elements for each picture falls within the limits determined by the first and second numbers and for rejecting the document when the activated number of elements is outside the limits.          The microprocessor unit of my document validator is adapted to be set up to feed information to the memories carrying the first and second numbers in response to the documents past through the system to cause the validator to learn to validate a different type of document. The universal document validator is readily adapted to be set up selectively to validate a plurality of documents of different types.

Abstract: TUNGSTEN LAMP FILAMENT WELDED JOINT TO LEAD            ABSTRACT OF THE DISCLOSURE In a joint between a coiled tungsten filament of an electric lamp and molybdenum lead, the lead connects integrally into a weld section which extends longitudinally within the coiled filament. The weld section may be formed by suddenly melting that portion of the lead involved in the joint, by pulse discharge, within an inert or reducing gas. The melted molybdenum wets the tungsten coil and is drawn by capillarity into the turns of the coil where it is rapidly chilled, and solidifies in a time interval too short for appreciable crystal growth and embrittlement to occur in the tungsten, the time interval being two seconds or less.

Abstract: ABSTRACT     The printability of electrical insulation composed of polymers having low surface energy, e.g., flurocarbon polymers, is greatly improved by incorporating a suitable particulate filler in the polymer, and shaping the filled polymer under conditions which result in the surface of the shaped polymer having irregularities which correspond to the particles of the filler.  Suitable fillers comprise particles having at least two dimensions in the range of 1 to 40 microns; glass fibers are particularly satisfactory.  In this way extruded insulating polymeric jackets for electrical components, e.g., strip heaters and wire and cable, can be marked by conventional methods, e.g., offset printing.

Abstract: ABSTRACT OF THE DISCLOSURE A method of producing a thin metal wire having a circular cross section is disclosed.  The wire is produced by providing a molten metal within an extruding device having a nozzle therein.  A strip of liquid coolant in motion at a speed of 200 m/min or more is then provided. The molten metal is extruded into the strip of liquid coolant in order to cool and solidify the metal and form the thin metal wire. A high quality thin metal wire is obtained by precisely adjusting the speed of the strip of liquid coolant relative to the speed of the extruded molten metal as well as the angle at which the molten metal is extruded into the liquid coolant strip.  The method is capable of economically and continuously producing a high quality thin metal wire on a commercial scale.  The method is effective in directly producing a thin metal wire having an amorphous, a nonequilibrium crystalline, or micro-crystalline structure.

Abstract: Abstract The volume of gases in a container or the volume of liquid in the container is determined by creating cyclic pressure waves in the gases and detecting the waves by a second transducer.  The signals produced by the second transducer are a function of the volume of gas in the container, and the volume of any liquid can be obtained by simple calculation.  The signals can also provide detection of an open container and, when coupled to signals relating to the velocity of a vehicle, can provide other data such as a miles-per-gallon reading.

Abstract: TIME SLOT ASSIGNMENT FACILITIES            Abstract Common resources normally assign a pair of time slots to each port circuit in a PCM switching system.This wastes time slots when the port circuit is used in a manner (voice only service) that requires only a single time slot. The disclosed arrangement eliminates the wasting of time slots by permitting the on-site reconfiguring the system resources so that, when desired, only a single time slot can be assigned to each port circuit.  This is accomplished by the removal of a first type of carrier control board (PDI) that controls time slot distribution and by the substitution therefore of a second type of control board (BPDI) that applies the first time slot of a pair to its normally assigned port circuit and applies the second time slot of the same pair to another port circuit on the same carrier that also only requires a single time slot.  This permits a given system to be configured initially in a first mode and then be subsequently reconfigured on-site so the port circuits of a carrier can each be assigned either one or two time slots.  This arrangement avoids the wasting of time slots or costly on-site modifications as service needs change.

Abstract: ABSTRACT OF THE DISCLOSURE A reusable control module mountable to a power-cartridge-operated interrupting module which includes a normally closed switch in shunt with a fuse. The control module houses a control circuit which ignites the power cartridge to open the switch. The control module includes two conductive shells threaded together to enclose the circuit, thereby providing a Faraday cage for the circuit and shielding the circuit from the environment. A current transformer is mounted in an exterior pocket in one of the shells over a mounting terminal thereon which extends out of the pocket to act as a single-turn primary for the transformer. The output of the transformer is connected to an input of the circuit. Circuit boards of the circuit are mounted within the shells, in part by a plastic plug, one end of which passes through one of the shells coaxially with a mounting neck. The other end of the plug has slots which engage and hold one edge of the boards. The plug contains a conductor connected to the output of the circuit. When the modules are mounted together via the neck, the conductor at the one end of the plug is electrically connected to the power cartridge and the shells can now carry the current in a protected circuit to the switch and the fuse. The plug is located on the axis of rotation of the shells when the shells are threaded together so that its holding and signal-carrying functions are not compromised.
