Granted: 1991-10-15
Abstract: TARP COVER SYSTEM FOR FLAT BED VEHICLES          Abstract of the Disclosure A  tarp cover system for flat bed vehicles includes inverted U-shaped bow members that extend transversely of the vehicle, the lower ends of the leg portions of the bow members being connected with carrier devices by means of which the bow members are displaced longitudinally of the vehicle. The bow members carry a tarp cover member that covers and uncovers the vehicle bed when the bow members are displaced   longitudinally   between   expanded   and contracted conditions relative to the vehicle.  The tarp  member  includes  side  portions  that  extend downwardly adjacent the outer surfaces of the leg portions of the bow members, and bottom flap por-tions that extend beneath the carrier devices and the  longitudinal  guide  tracks  within  which  the carrier devices travel.   In order to produce com-pactness of the tarp system when the bow members are in  the  collapsed  conditions,  successive  carrier devices are guided alternately on vertically spaced pairs of inner and outer guide rails, respectively, contained within each of the guide tracks.

Title: Assembled cam shaft and method of manufacturing same
Inventor: BREUER HANS-JUERGEN
IPC: B21D26/033
Filed: 1987-09-30
Granted: 1992-01-28
Abstract: Abstract An assembled camshaft is disclosed, comprising a shaft tube and elements such as control  cams,  bearing rings, gear wheels,  or beveled gears,  which are slid onto the shaft tube and fixed in position by expanding the shaft tube  in  the  region  of  the  slid-on  elements  by  the application  of   internal   pressure.     By  subjecting longitudinal  portions  of  the  shaft  tube  to  plastic deformation in the region of slid-on elements undergoing predominantly elastic deformation, it has been found that a torque-transmitting  fit  of  elements  may  be  achieved without   any   thermal   processing,   thereby   avoiding dimensional changes typical of prior art camshafts.

Abstract: This invention relates to articles comprising a substrate bearing a coating formed from a blend of polymers.  Many articles having the desired properties of durability, strength, optical clarity, can be adversely affected by the surfaces of those articles.  It would be desirable to provide a coating material that could alter the surface of an otherwise useful article.  This invention provides an article comprising a substrate bearing an optically clear, non-crosslinked coating formed from a blend comprising at least one polymer containing carbonylamido functional groups and at least one hydrophobic polymer substantially free of acidic functional groups.  The coating is useful for promoting adhesion, increasing the hydrophilicity of the surface of the article, and increasing receptivity of the substrate for aqueous based inks.

Title: Dishwashing apparatus including a flip-top solid detergent dispenser
Inventor: LAKHAN HARESH C
IPC: A47L15/44
Filed: 1988-04-29
Granted: 1993-10-12
Abstract: ABSTRACT OF THE DISCLOSURE      A dishwashing apparatus (1) designed in such a manner as to have one incoming waterline (79).  Solid additive sources, including  rinse  aid  (24)  and  detergent,  are  situated  in containers mounted on top of the dishwashing apparatus (1), thus saving space. Said additive sources are sprayed with water and fed through product nozzles by means of a pump (15) in  order  to  form  additive  solutions.    Said  dishwashing apparatus  (1)  saves  rinse water  containing  rinse aid and chlorine sanitizer at the end of a complete cycle and reuses it during the beginning of the second complete cycle thus saving on hot water, rinse aid and sanitizer.     A flip-top detergent dispenser  (30) comprising a base means  (31)  having a funnel-shaped interior,  a nozzle  (22) positioned within the interior of said base means,  and a detergent container support means (32) connected by a hinge means (33) to said base means (31).  Said detergent container support means  (32)  is designed to hold only a particular shaped detergent container (23), thus helping to insure that only suitable detergent products are used in the warewashing apparatus.  The flip-top detergent dispenser (30), mounted on top of the dishwashing apparatus (1),   is designed so that the detergent container (23) can be inserted into and removed from the detergent  holder  support means  (32)  only  in an upright position to prevent dripping of detergent solution onto the user.     Automatic safety features include a cam (66) situated next to the base means  (31) which will not be activated unless  a  particularly  shaped  detergent  container  (23)  is situated  in  the  detergent  support  holder  (32)  and  the detergent support holder (32) is closed.  Only when the cam (66)  is activated can water spray up through the product nozzle (22).  Also, preferably, the detergent support holder (32) has open areas so that labels including instructions and warnings can be read on the solid detergent container (23).     In addition, a circular metallic ring   (37) having a plurality  of  holes  is  situated  around  the  funnel-shaped interior  of  said  base  (31)  of  said  flip-top  detergent dispenser (30).  Water is flushed through the holes of said circular  metallic  ring  (37)  at  designated  times  in  the warewashing cycle serving to insure that the detergent is rinsed down through the funnel-shaped interior of said base (31) and that it does not conglomerate there.  This results in a savings of solid detergent source.

Abstract: Case 9-16717/17188/GTP 533/GTP 534 PHOTOGRAPHIC COLOR COPYING APPARATUS      AND EXPOSURE CONTROL PROCESS     ABSTRACT OF THE DISCLOSURE     Originals to be copied are scanned spectral photometrically by regions and from the spectral values obtained thereby, color extract values adapted to the spectral sensitivity variations of the copy material are formed by electronic or computer filtering.  The color extract values are then evaluated for the determination of the necessary amounts of copying light.  The spectral values are simultaneously used for image analysis and additional control of the exposure. The process avoids expensive optical filters and makes an image analysis which yields a greater amount of information, and thus a more extact determination of the amounts copying light, possible.

Title: Multiple post for raising and transplanting seedlings and method of manufacturing the same
Inventor: TSURU RYUZO
IPC: A01G9/10
Filed: 1988-11-14
Granted: 1992-09-22
Abstract: ABSTRACT The invention relates to a multiple pot comprising individual pots interconnected by connector portions so as to be capable of being pulled individually from the multiple pot or in rows.  The multiple pot is used to raise and transplant seedlings of plants.  The invention also relates to a method of manufacturing the pot.  The pot is designed especially to promote growth of roots across the side walls of the individual pots after transplantation.  Also, the resistance encountered when the multiple pot is unfolded is reduced. Further, the individual pots are uniform in size.  These features arise from special connector portions, which are formed by applying a waterproof paste discontinuously between two adhered films. Furthermore, a water-soluble paste is not applied around the edges of the individual pots created when the multiple pot is unfolded.  The multiple pot is fabricated by continuously carrying out three steps. In the first step, the waterproof paste is applied in a given pattern while continuously pulling out two continuous thin films.  In the second step, folds are formed in the belt resulting when the two thin films are adhered together and the belt is folded in a zigzag fashion to form layers.  In the third step, the water-soluble paste is alternately applied to the front side and the rear side of adjacent layers of the belt and between the folds.  Then, the belt is refolded, and pressure is applied to it to stick together the folded layers.

Abstract: ELECTROLYTE FLOWMETER                           ABSTRACT           A device for measuring the flow rate of an electrolyte into an electrolytic cell for electrowinning.  An electrolyte supply conduit transports electrolyte to the electrolytic cell.  A transparent tube extends upwardly from the electrolyte supply conduit.  The transparent tube has a closed end and an open end.  The open end is connected to the supply conduit to permit electrolyte from the supply conduit to flow freely to a level in the transparent tube.  The level of electrolyte in the transparent tube dividing the transparent tube into a lower portion containing electrolyte and an upper portion above the electrolyte.  An air supply conduit supplies air to the upper portion of the transparent tube.  The level of electrolyte in the transparent tube is proportional to the flow rate of electrolyte to the electrolytic cell.
