Title: Dual inlet impregnation for mechanical pulping
Inventor: KOTELES RUDY
IPC: D21D5/00
Filed: 1988-05-13
Granted: 1992-11-17
Abstract: ABSTRACT OF THE DISCLOSURE      Two different types of comminuted cellulosic fibrous material (e.g. wood chips) are commonly fed to a single impregnator and refiner in the production of mechanical pulp.  First and second presteaming vessels are operatively connected through plug screw feeders to a header, in turn connected to a impregnator (such as an inclined screw impregnator).  The impregnator is in turn connected to a refiner.  A control device controls the speeds of operation of the motors for the plug screw feeders, thereby controlling the mix of different material species from the presteaming vessels to the impregnator to thereby control the composition of the mechanical pulp being produced.

Abstract: The invention is a method of hydrostatic weighing of a human body and a kit for use in hydrostatic weighing. The method comprises filling with water and closing a container which the person being weighed can grasp, having the person being weighed grasp the filled and closed container and sink himself in a pool of water, remove from the container a quantity of water just sufficient to suspend himself between the bottom of the pool and its surface when he has exhaled as much air as possible from his lungs, determine the weight of water needed to refill the container and determining the density of the water, e.g., by taking its temperature. The kit comprises a container with a screw cap which is capable of being grasped by a person being hydrostatically weighed, means such as a graduated cylinder for determining the weight of the water required to refill the container after it has been adjusted by removal of water to suspend the person in water, a weight which is necessary if the person being weighed floats in water, and a thermometer to determine the density of the water being used for the hydrostatic weighing. A nose clip and data sheet may be included in the kit, if desired.

Abstract: AN IONIZATION CHAMBER FOR MONITORING RADIOACTIVE           GAS              Abstract of the Disclosure A  small  enclosed chamber  with  an electrostatically charged  electret  attached to the inner chamber wall.  A filtered hole in the chamber permits radon or other radioactive gas to enter by diffusion.   Positive or negative ions (depending  on  the  polarity  of  the  electret charge) formed in the chamber air by the decay of the radioactive gas move to and collect on the electret surface by virtue of its electrostatic attraction to ions of opposite polarity.   These ions accumulate and cause a measurable reduction in the surface voltage  of the electret which reduction is proportional to the time integrated concentration  of the  radioactive  gas  in  the chamber.   The electret surface voltage of the reduction value is used to calculate the average concentration of the radioactive gas during the exposure  period.    The  electret  thickness  and chamber volume can both be increased to increase the sensitivity of the invention to radioactive gases such as radon, tritium or carbon-14 dioxide or such other radioactive gases.

Abstract: ABSTRACT OF THE INVENTION A rotary atomizer (20) includes a manifold assembly (22) adapted to be attached to a mechansim for moving the atomizer and an air bearing turbine motor housing assembly (21) releasably secured to the manifold assembly.  Sources of pressured fluid for actuating the atomizer and coating fluid are connected to the manifold (29) which has fittings (32, 33, 34, 35, 36) for releasably sealing to apertures (42) in the rear cover (43) of the housing assembly.  The opposite end of the housing includes a shaping air cap (24) and a shaping air ring (25) which cooperate to define an annulus for discharging a thin ring of shaping air over the peripheral edge of an atomizer bell (26) to direct fluid particles toward a target.  Exhaust air from the turbine motor (46) is vented to the inside of the housing and directed to a chamber (79) behind the atomizer bell  to aid in directing the fluid particles.  A magnetic speed pickup (103, 104) generates a signal which is coupled through a circuit (105, 106) that electrically isolates the high voltage which is applied to the atomizer to electrostatically charge the coating particles.

Abstract: A reclosable extruded plastic fastener for joining sheet material such as walls of bags, and method of making the same. The fastener comprises a grooved female profile and a complementary hook-headed male profile, and a stabilizing structure especially advantageous when pressing the profiles together into closed fastener assembly. The female profile has a generally square base with at least one stop shoulder to minimize tipping of the female profile about a thin, thermal bridge minimizing, heat transfer limiting stem. The hooked jaw arms of the female profile may have various geometric shapes. The male profile has an interhooking barb which interengages with the hooked jaws of the female profile. Stabilizing ribs are spaced from the head, but the rib at the inner side of the head is closer to the head than at the other or outer side, so that there is a desirable differential fastener separating relationship retaining the fastener efficiently with greater hold against opening due to internal bag forces.
