Granted: 1999-05-18
Abstract: A method of removing, reducing or detoxifying organic pollutants from a fluid, water or air, by contacting the fluid with a photo-reactive metal semiconductor material in the presence of ultraviolet light of a wavelength to activate the photoreactive material, is improved by simultaneously contacting the photoreactive material with a substance that accepts electrons and thus inhibits hole-electron recombination. Such substance will be such as to readily accept electrons either from the conduction band or from superoxide ions, and to rapidly dissociate into harmless products.

Title: Electro-pneumatic spring and service brake actuator
Inventor: LATVALA BRUCE EARL
IPC: B60T17/08
Filed: 1991-06-13
Granted: 2001-09-04
Abstract: An electro-pneumatic braking system includes a tandem brake actuator (12) including a service brake actuating section (16) and an emergency/parking spring actuated section (18). Hold-off pressure is communicated to the emergency/parking section through a three-way solenoid valve (54) from a pressure reservoir (42), and communication to the service actuator is controlled by electro-pneumatic modulator (56). Service pressure is taken both from the branch of the conduit communicating with the air reser-voir (42), but also from the hold-off pressure in the emergency/parking reservoir (34). Accordingly, only a single line communi-cates fluid pressure from the reservoir to the brake, and service brake response; time is improved because the hold-off pressure and the emergency/parking section of the actuator is used as a small reservoir immediately adjacent the service actuator.

Title: Method and apparatus for currency discrimination and counting
Inventor: RATERMAN DONALD E
IPC: G07D7/00
Filed: 1991-01-14
Granted: 1995-07-18
Abstract: An improved method and apparatus for discriminating between currency bills (17) of different denominations uses an optical sensing (18) and correlation technique based on the sensing of bill reflectance characteristics obtained by illuminating (22) and scanning a bill along its narrow dimension.  A series of detected reflectance signals are obtained by sampling and digitally processing (30), under microprocessor control, the reflected light at a plurality of predefined sample points as a currency bill is moved across an illuminated strip (24) with its  narrow dimension parallel to the direction of transport of the bill.  The sample data is subjected to digital processing, including a normalizing process, whereby the reflectance data represents a characteristic pattern that is unique for a given bill denomination and incorporates sufficient distinguishing features between characteristic patterns for discriminating between different currency denominations.

Abstract: A method and apparatus for sealing the gap between adjacent boiler tubes of a panel wall thereby making the panel wall air-tight.  First and second sealing members are secured to opposite sides of adjacent boiler tubes thereby defining a gap therebetween.          This gap is then filled with a metal salt solution which is dried in place so as to leave a residue behind.   Subsequently, this residue is further heated which converts it to a metal oxide that forms an air-tight ceramic plug.  This plug possesses properties which make it resistant to deterioration once the panel wall goes into service.

Abstract: In hinge  tracks with rubber mountings (5) in which rubber-lined tubular steel bushes mount track pivot pins (20), the pin ends are usually provided with screwthreaded projection portions so that the steel bushes (10) are motion-free braced relative to each other and relative to the track pivot pins (20) by means of nuts.  In order to improve  the  useful  life  of  the  rubber  mounting  (5)  and  reduce maintenance,  a rubber-lined spreadable bush (10) with at least one dividing gap (11) is proposed instead of the tubular bush.  The internal width (25) of the bush (10) which is pressed into position is less than the diameter (27) of the track pivot pin (20).  The inserted track pivot pin (20) expands the bush (10) which is pressed into the chain link member (1).  In that case the track pivot pin (20) is braced in the bush (10)  and  is  fixed  in  its  longitudinal  direction  by  frictional engagement and in the peripheral direction by frictional engagement and/or positively locking engagement. The screw means for bracing the bushes  (10)  are eliminated and an increase in the rubber mounting surface is achieved by virtue of using the screwthread space of the screwthread arrangement. That affords an increased service life for the rubber mounting in a maintenance-free design configuration.

Abstract: An improved design for an injection molding apparatus for creating of products from fluid plastic material wherein a hydraulic flow divider can be used for simultaneously actuating of multiple hydraulic injectors which need not be linearly positioned.  This molding apparatus is usable with a hydraulic flow divider since a unique configuration of a fixed frame with a cage mounted movably therein and a hydraulic cylinder assembly mounted movably within the cage allows the injection molding apparatus to use the same amount of hydraulic fluid during each and every stroke regardless of the length of the stroke of the rod relative to the nozzle.  This unique capability is achievable by allowing the hydraulic cylinder assembly in its entirety to move within a predefined cage configuration even after the entire stroke is completed in order to allow the cylinder to accept the amount of powering hydraulic fluid associated with a single complete stroke.  Further included in this design is a unique position indicating device located externally on the apparatus to indicate the relative positioning internally between the nozzle rod and the nozzle rod tip opening and to indicate the positioning of adjustment thereof.
