Title: Electrostatic powder coating utilizing multiple spray streams
Inventor: MATSUNAGA MASAHUMI
IPC: B05B5/03
Filed: 1992-05-29
Abstract: ABSTRACT OF THE INVENTION            ELECTROSTATIC POWDER COATING UTILIZING MULTIPLE SPRAY STREAMS WITH PULSED ELECTROSTATIC FIELD AND SPRAY  PATTERNS          An electrostatic powder coating gun splits a pressurized gas-powder mixture into a plurality of separate electrostatically charged spray streams to achieve a high degree of directionality and reduce deflection.  The powder particles in the mixture may be electrostatically charged while inside one or more chambers in the gun, either by an applied DC electrostatic field or by friction.  The flow paths traversed by the spray streams may be arranged and/or oriented so as to advantageously powder coat a particular surface configuration, such as the inside of a container.  Alternatively, electrostatic charging of powder particles may occur via a plurality of electrodes located external to the gun, with at least one external electrode associated with each spray stream.  To further reduce deflection, the mixture may be sprayed from the gun in a pulsed manner.         Additionally, the electrostatic fields created by the external electrodes may be pulsed between an "off" and "on" condition during spraying.

Abstract: Abstract A method of forming a nonwoven web having delayed antimicrobial activity, in that the web does not exhibit antimicrobial activity upon its formation but develops such activity within from about three hours to about 30 days thereafter without any post-formation treatment, which method involves the stepsof (1) melting a mixture consisting of a thermoplastic polyolefin, an additive, and a retardant coadditive; (2) forming fibers by extruding the resulting melt through under defined conditions of shear and throughput; (3) drawing the fibers; and (4) collecting the fibers on a moving foraminous surface as a web of entangled fibers. The additive is a defined siloxane quaternary ammonium salt having a molecular weight of from about 800 to about 2,000 and a polydispersity of from 1 to about 2Ø The additive is present in an amount of from about 0.5 to about 2.0 percent by weight, based on the amount of thermoplastic polyolefin. The retardant coadditive is a high surface area particulate inorganic or organic material which is insoluble in the polymer at both ambient and melt-extrusion temperatures, is present in an amount of from about one-half to about two times the amount on a weight basis of the additive, has a surface area of from about 50 to about 500 m2, and is capable of being at least partially being coated by the additive. - 16 -

Title: Bottled water chilling system
Inventor: BURROWS BRUCE D
IPC: F25B21/02
Filed: 1991-11-05
Abstract: A chilling system is provided for chilling or cooling a supply of water (12) or the like to a selected low temperature suitable for drinking and other uses. The chilling system includes a thermoelectric heat transfer module (26) having a cold side for extracting heat energy from water contained in a reservoir (18), and a hot side for transferring the extracted heat energy to a circulating heat transfer fluid (43). In particular, the hot side of the module (26) is in thermal communication with a manifold block (40) through which a heat transfer fluid (43) such as water is circulated by a pump (44). The pump (44) circulates the heat transfer fluid through a heat exchanger (28) for dissipating the extracted heat energy. In addition, the same pump (44) drives an impeller (56) within the reservoir (18) to maintain the reservoir contents at a substantially uniform temperature level, and further may drive a cooling fan (60) for providing a convective air flow across the heat exchanger (28).

Inventor: BOKERMAN GARY N
IPC: B01J21/12
Filed: 1993-03-11
Abstract: PRODUCTION OF ORGANOSILANES FROM POLYSILANES    ABSTRACT           The present invention is a process for the production of organosilanes from the high-boiling residue resulting from the reaction of organohalides with silicon metalloid in a process typically referred to as the "direct process."  The present process comprises forming a mixture comprising a organotrihalosilane and the high-boiling residue in the presence of hydrogen gas, a hydrogenolysis catalyst and a redistribution catalyst.  The organotri-halosilane and high-boiling residue are converted into commercially useful di- and triorganosilanes and organohydrosilanes.  The present process results in consumption of the organotrihalosilane rather than the net increase which typically occurs in the absence of the redistribution catalyst.

Abstract: METHOD AND APPARATUS FOR PORTABLE DISPENSING OF FOAM MATERIAL          ABSTRACT OF THE DISCLOSURE     A pressurized solution of a material with a dissolved gas is maintained and dispensed in a system that allows the material can be dispensed as a foam at any location.   The system is portable and avoids the need for a large mixing apparatus at the location.  The system includes a portable container having a movable member defining an expandable chamber.  The chamber is filled the material/gas solution from a pressurized source of solution which may be at another location.  Force is maintained on the movable member to keep the material/gas solution under pressure.  The material/gas solution is maintained under pressure in the container to avoid premature foaming of the solution by the maintaining force on the movable member.  The force can be provided in various ways, including the use of a predetermined amount of fluid in the container on the other side of the movable member from the chamber or the use of an external source of pressur-ized fluid.  The material/gas solution is discharged from the container and dispensed using a gun to atmospheric pressure to release the gas and form a foam.

Title: Sensors
Inventor: DAMES ANDREW
IPC: G01N29/036
Filed: 1991-12-05
Abstract: A density sensor comprises a cavity arranged to receive the gas whose density is to be sensed. The cavity is divided into two chambers by a flexibly mounted diaphragm. A piezoelectric excitation device at one end of the cavity is used to excite the gas in the cavity into resonant vibration in a mode having an anti-node at the diaphragm, which causes the diaphragm to vibrate with the gas.  Another piezoelectric device senses the vibration, whose frequency is a function of the known mass of the diaphragm and the density of and speed of sound in the gas. This last parameter can be sensed by exciting the gas in the cavity into resonant vibration in a second mode having a node at the diaphragm, so that the diaphragm does not take part in the vibration. Alternatively, it can be sensed by providing a second cavity, also arranged to receive the gas but not having a diaphragm, and resonantly vibrating the gas in the second cavity.
