Abstract: A monitoring apparatus and method are disclosed for monitoring the occurrence of a plurality of events in a cyclical process. An event transducer detects the occurrence of such events in such process, a progress transducer detects the progress of such process, a search means searches for events by sensing whether respective events occur at expected positions in the progress of such process, and a self-delete means automatically prevents the search means from searching for a prescribed event at its expected position when such prescribed event is not sensed during a predetermined number of cycles of such process. In the preferred form, the monitored process is the cyclical operation of an endless conveyor which is automatically shut down when a rip occurs; the self-delete means reduces unnecessary nuisance shut downs.

Abstract: An alcohol mixture suitable for combining with gasoline is produced by contacting synthesis gas at elevated temperature and pressure with an oxide complex catalyst containing copper, thorium, an alkali metal and at least one other specific element.

Abstract: A two pole stationary coil rotary magnet motor which provides for increased work and reduced rotary inertia. The motor consists of two main assemblies, a rotor assembly contained within a rotor casing and a stator and housing assembly surrounding the rotor casing. One end of the casing is closed, whereas the other end is open to eliminate the need for a dynamic shaft seal. Fluid enters the casing at the open end thereof to provide a lubricating fluid for the rotor bearings and a heat conductive path. The rotor casing isolates the critical movement of the rotor from the contaminated atmosphere of the stator environment and allows replacement of the stator assembly without disturbing the rotor assembly. A permanent magnet rotor may be formed using one or more rare earth magnets which may be suitably bonded to the rotor shaft. A protective cover surrounds the rotor magnets to eliminate potential rotor magnet breakage contamination.

Abstract: A process for impregnating green wood with oil-soluble metal salts is described. The method comprises(a) contacting the green wood with an aqueous system comprising(i) water,(ii) at least one oil-soluble metal salt of an organic carboxylic acid, and(iii) at least one surfactantfor a period of time sufficient to enable the metal salt to penetrate into the wood, and(b) removing the wood from contact with the aqueous system. Good penetration of the metal salt into the green wood is realized by this method when conducted under vacuum, at atmospheric pressure or at elevated pressures. Preferably, the metal salt is a preservative such as a fungicide, and the aqueous system also contains other desirable components such as fire retardants, coloring agents and insecticides.

Abstract: Continuous strip accumulator includes a convolution transfer annulus providing for controlled expansion and contraction of the stored convolutions between inner and outer sections within the accumulator. During mill match operation of the accumulator, the convolution transfer annulus is retained against movement but still provides support for the strip material as it moves from the inner section to the outer section. A differential drive between the entry and exit pinch rolls provides for mechanical synchronous operation of the entry and exit pinch rolls during the mill match mode. During the welding mode, when it is desired to replenish the supply of strip material, movement of the incoming strip is stopped and the convolution transfer annulus is driven by the differential drive in a direction causing positive transfer of the convolutions from the outer section to the inner section in mechanical synchronism with the exit pinch rolls to provide a continuous uninterrupted supply of strip material to the mill.

Abstract: A roof flashing and method of making same in which both the collar and base member of the flashing are made of elastomeric material. The base member is molded first and has an opening therein surrounded by a stepped flange provided with a series of circumferential slots therein. The collar is molded onto the base member during a subsequent molding operation in which the material of the collar is injected through the slots and completely around the top, bottom and inner side edge of the flange to form a series of closed loops thus providing a positive mechanical lock between the collar and base member. Also, the heat of the elastomeric material of the collar during the second stage molding process causes some melting of the elastomeric material of the base member whereby the collar and base are also fused together.

Abstract: A method and apparatus for printing directly onto a surface employs a printing plate through which pigmented fluid passes directly onto such surface and a reservoir for supplying a highly uniform distribution of pigmented fluid preferably at a relatively accurately controlled pressure to the printing plate. A plurality of minute openings through the printing plate forming a printing image thereon controllably pass the pigmented fluid directly onto such surface. These openings may be tapered to reduce misting and to facilitate breaking surface tension as pigmented fluid is transferred directly to the surface. The reservoir may be a porous, permeable sintered titanium cylinder about which the printing plate is mounted. Moreover, the invention includes a method of forming such a printing plate employing optical, and preferably laser, scanning techniques so that the printing image on the printing plate accurately represents the original image.

Abstract: A hot air modulating valve for mixing hot air with cold air flowing in a duct, the modulating valve having a torque motor operated pilot valve to position the modulator valve to maintain a predetermined temperature of the hot air-cold air mixture. The temperature of the mixture is sensed by a thermistor which in conjunction with a tri-mode (proportional plus integral plus derivative) electronic controller which provides an input current signal to the torque motor to position the modulator valve in proportion to the input current signal, produces zero steady state errors, and provides an anticipation effect to compensate for control system time lags. The controller has auxiliary inputs which when exceeding predetermined values switch the air mixture temperature at the thermistor to a lower setting. The modulating valve has a relatively low gain during the initial portion of its opening stroke to improve system dynamic stability and has a position feedback to the torque motor operated pilot valve.

Abstract: In an electrolytic capacitor, there is provided an improved header for closing the open end of a capacitor can. The header includes a rigid insulating or metal body having at least one terminal passing therethrough, and a resilient elastomeric cover having inner and side walls molded about respective surfaces of the body and a tubular terminal sealing portion molded interiorly about a hole in the body through which the terminal passes. The tubular portion has formed at its inner annular wall a plurality of axially spaced apart annular sealing beads which annularly engage the terminal with compressive force to effect respective axially spaced apart line seals. When assembled under compression between axially spaced components of the can, the inner and side walls of the cover cooperate with such components to provide plural seals against leakage of electrolyte from the can about the rigid body while the tubular portion seals against leakage at the terminal.

Abstract: Plastic tubing of extruded polybutylene and the like has an end reformed into a structural bulb sealing surface which includes a stop flange permitting the tube to be drawn into sealing engagement with a mating part. The tube end is reformed in a press or jig which includes two molds, with the tube end projecting through one mold and toward the other. The other mold is normally chilled or cooled but includes an I.D. mandrel or pin projecting therefrom. The pin is insulated from the other mold. The pin may be heated and/or cooled during the reforming cycle of the process to enable uniform heating of the projecting tube end from both the inside (I.D.) and outside (O.D.) of the tube end. The process and apparatus of the invention provides a more uniform and integral reformed tube end. The cycle time of the process may also be reduced resulting in greater productivity with less energy consumption.
