Abstract: A funnel is disclosed for use in brewing beverages such as coffee, tea and the like and for discharging the beverage into either of a plurality of spaced reservoirs below the funnel. The funnel includes an upstanding side wall, a bottom wall, and flow channel means associated with the bottom wall which communicates between the interior of the funnel and a discharge port spaced from the center of the funnel for selective discharge of liquid into alternate reservoirs by turning the funnel. Stop means provided at a selected radial position on the funnel cooperate with limiting switches or the like on the brewing machine to prevent brewing unless the funnel is in the proper location for discharge into a reservoir.

Abstract: A teleprinter includes a carriage for conveying a dot matrix-type print head along an operating path parallel to a print-receiving surface. The carriage is mounted on parallel-spaced support rods by means of spaced bearings slidably engaged to one of the support rods, and a pair of perpendicularly-aligned guide rollers which engage the other guide rod. The carriage is advanced by a drive belt which extends along the carriage operating path and is attached to the carriage at either end. A stepper motor coupled to one of the pulleys drives the belt to position the carriage. A removable cartridge on the carriage contains an inked ribbon which is advanced with movement of the carriage by a drive gear engaged to the drive belt. A unidirectional clutch prevents the inked ribbon from moving in a reverse direction during carriage return.

Abstract: A dot matrix-type print head for forming a character-defining array of individual dots on a print-receiving surface includes a plurality of parallel-spaced print wires arranged in a vertical plane perpendicular to the print receiving surface. The print wires are individually actuated by respective actuator assemblies which each include a stationary portion consisting of an end plate, a bobbin, a solenoid winding, and a spring, and a movable portion consisting of a magnetic armature attached to the associated print wire. Upon energization of the solenoid winding the resulting magnetic flux displaces the magnetic armature and causes the print wire to impact the print-receiving surface.

Abstract: A system for electronically metering an A.C. electrical power system to derive performance parameters such as real and reactive power useful in revenue metering and fault protection applications. Voltage and current sensors associated with the power system provide isolated output signals proportional to the voltage and current in the system. From these signals finite-duration impulse-response filters periodically determine Walsh function correlation coefficients by integrating the voltage and current signals at least once during each period of the power system and periodically sampling and holding the integrated signal in sequence with the integration.

Abstract: This invention relates to a method for forming metal battery terminals and to the terminals produced thereby for use with battery containers fabricated from thermally deformable materials such as polypropylene which involves casting the metal directly into place within and through the wall of such container.

Abstract: A radiation apparatus for cosmetic, photobiological and/or photo chemical purposes containing at least one ultraviolet ray source and devices for operation for the production of the ignition voltage and operating current and a filter device for emitting rays in the region of 320 nm to 450 nm and for cutting out short wave rays below 320 nm and long wave rays above 800 nm and preferably above 450 nm.

Abstract: A fluid treating apparatus and method are provided which employ finely subdivided surface active particles arranged in loose bed form and confined within a treating tank by means which prevent the escape of such particles but which permits fluid flow therethrough at a high rate with a minimum pressure drop. In an important embodiment, the apparatus and method of this invention are particularly directed to the treatment of water with fine mesh ion cation exchange resin particles of below 50 mesh size, and preferably 100 to 200 mesh or smaller, measured on a dry basis.

Abstract: Substrates, especially those having plated metal surfaces, and subjected to passivation treatments in baths that incorporate one or more film-forming agents at least one of which does not require chromium and includes anions or cations of elements other than chromium. Typically, the anions or cations are introduced as bath-soluble salts which react with the plated surface of the substrate to form an adherent, coherent passivation surface film. Also present within these baths are a source of hydrogen ions and a bath-soluble carboxylic acid or derivative activator for enhancing the rate of the passivation reaction. Articles passivated in baths incorporating these film-forming agents have a hydrophobic surface that exhibits corrosion resistance and that typically has a bright finish.

Abstract: Means for and method of electro-polishing generally planar upright surfaces of relatively large areas on machine parts of various shapes and sizes. The means and method constitute improvements on the method and apparatus disclosed in my prior U.S. Pat. No. 4,127,459 dated Nov. 28, 1978. In a preferred embodiment the surface to be electro-polished is a pattern-free, directionless, abrasively finished metal surface. When such a surface is electro-polished in accordance with this invention the resulting polished surface is waveless, ripple-less and uniformly smooth in all directions so as to exhibit superior anti-stick and release properties. Such a surface is particularly suited for numerous purposes such as head box components for paper-making machines.

Abstract: A vehicle mounted spray boom assembly includes a breakaway spray boom and shock absorbing means for absorbing the shock on the boom assembly when a boom returns to normal position after striking an obstacle. The shock absorbing means includes a swing cylinder for rigging in and rigging out the spray boom and a tilt cylinder for tilting the boom when the boom has been rigged out. Upon occurrence of shock after an obstacle is struck, a portion of the hydraulic fluid in the swing cylinder is forced into the tilt cylinder to lift the spray boom to dissipate the shock. In addition, another cylinder may be provided for absorbing shock imparted to the boom due to vertical movement of the boom. Also the swing cylinder and tilt cylinder are hydraulically connected in parallel so that when rig out has been completed, pressurized hydraulic fluid continues to be ported to the tilt cylinder to elevate the end of the boom.

Abstract: A fault indicator for indicating the occurrence of a fault current in an electrical conductor includes a reset circuit operable from an external electrical excitation source. The external source is connected to the reset circuit by a cable formed from a flexible electrically insulating tubing segment within the lumen of which an electrically conductive coating is disposed. The resulting high impedance electrical interconnection reduces the danger of electrical shock from inadvertant contact with the cable or the fault indicator circuitry, and precludes the source from being adversely affected should the cable become shorted to ground.

Abstract: A touch control is provided for a spin-casting fishing reel employing a freewheeling flywheel adjacent the line-discharge end of a non-rotating line spool, which flywheel rotates freely of the line take-up or retrieval mechanism and engages with the line and spins as the line unwinds from the spool. A touch control member carried on the reel is operable by manual pressure to selectively retard rotation of the flywheel to control or feather line discharge from the reel.

Abstract: A control system for controlling a motor having a plurality of electromagnetic field windings adapted to be separately energized by switching circuitry to control rotation of a rotor in the motor. Digital circuitry generates a plurality of logic signals, one for each respective motor field winding to cause the switching circuitry to energize the field windings in a two phase on mode, a one phase on mode, or in one of a plurality of fractional phase on modes. A signal command source provides a plurality of digital signals to select or gate the desired phase on energization mode of the field windings in response to a feedback signal derived from detecting rotary movement of the rotor. Related methods of controlling a multi-phase motor with digitally generated variable phase modes are also disclosed.

Abstract: A motor control system for use in a high speed teleprinter or the like for controlling the rotational position and movement of a rotor, and apparatus driven by the rotor, by detecting back EMF induced into an unenergized field winding by rotational movement of the rotor. The output and input terminals of a first amplifier responsive to a first motor control signal, and a second amplifier responsive to a second motor control signal, are reactively coupled such that the amplifiers respond to either motor control signal to develop a signal simulating the signal into an unenergized winding of the motor due to mutual inductance with an energized winding. A differential voltage comparator provides a feedback signal indicative of motor performance upon comparing the simulated signal with the signal actually induced.

Abstract: A method and apparatus is provided for removing large volumes of contaminants or for recovering valuable minerals present in trace amounts or greater quantities by ion exchange treatment of phosphoric acid liquids or the like as they flow through a resin bed wherein ions in the liquid are sorbed into the resin by an ion exchange mechanism. The resin bed is folded, moving bed which exhibits all of the advantages of a packed ion exchange resin bed. Laminar flows are developed at times in the moving bed system, while the moving bed used is of a "folded" type having a maximum height approximately one-third that of conventional, unfolded countercurrent units. The ion exchange treatment occurs within a loading vessel resin bed, the beads in the feed portion of which become exhausted and sequentially move out of the loading vessel for subsequent regeneration and rinsing, followed by eventual return to the loading vessel.

Abstract: A clutch or brake assembly is disclosed for controlling the relative rotation between two rotary members. Wedge means are carried between a pair of facing cam plate surfaces by an axial core member. The wedge means are axially movable with respect to the core member but prevented from rotating about the core member. The wedge means extend beyond the ends of the core member but, when the cam surfaces are aligned, are spaced therefrom to permit relative rotation between cam surfaces and the core member. When the cam plates are moved out of alignment, the distance between them is less than the axial length of the wedge means, causing the wedge means to wedge tightly between the cam plates. Because the wedge means is prevented from rotating relative to the core member, when it is wedged or locked between the cam plates they are also prevented from rotating relative to the core member.

Abstract: A product grouping station in a system for offloading bacon strips or the like comprises hydraulically-actuated lifters which lift groups of the bacon strips clear of the unidirectionally driven conveyor as they proceed away from the transfer station, and then release the groups in time sequence to achieve separation on the conveyor. The product grouping station is particularly adapted to handling thin strip-like products such as bacon slices, and employ novel control circuitry to obtain a continuous uniform operation for the offloading system which does not interfere with the operation of the continuously moving conveyor belt.

Abstract: A periodontal powder comprising approximately 288 grams of evenly exsiccated potassium alum powder and approximately 144 grams of sodium bicarbonate powder. Flavoring, sweetening, coloring, scenting and antiseptic ingredients are added.

Abstract: A cupola installation having a top charging opening and a vibratory feeder mounted to discharge into the top opening from one side. The skiphoist associated with the cupola carries two charging buckets, one for discharging charge material into the top charging opening in the stack while the other is for simultaneously discharging material into the pan or hopper of the vibratory feeder. When the empty charging buckets are lowered, the vibratory feeder is operated to discharge its load into the top charging opening. The use of two charging buckets permits a charge material of a type not suitable for charging along with the main charging material, to be separately charged in a gentler manner. For example, briquettes of cast iron borings and chips or of steel turnings are easily broken into objectionable fines when handled and charged in a conventional manner. Cooperating equipment associated with the trim platform assists in the loading of charge material into the separate charging buckets.

Abstract: A photopolymerizable system is provided as a latex system that is an oil-in-water polymer emulsion including particulates of water-insoluble polymers in combination with a water-soluble or water-dispersible, light-sensitive polymer having multiple light-sensitive moieties. Prior to coating onto a substrate, the system is a three-phase precursor emulsion of the emulsion particulates, the water phase, and the light-sensitive polymer. After coating, the bulk of the water phase is evaporated off, leaving a two-phase system of the emulsion particulates surrounded by the light-sensitive polymer. When selected areas are subjected to actinic radiation, a water-insoluble matrix is formed, the matrix containing cross-linked light-sensitive polymer having dispersed therethrough and/or included therein the water-insoluble polymer particulates, thus forming oleophilic image areas.
