Title: Aqueous coating compositions
Inventor: SPENCER ARTHUR T
IPC: E01B27/10
Filed: 1988-08-11
Granted: 1995-04-18
Abstract: A coating composition particularly adapted for can coatings is prepared by the addition polymerization of a monomer such as styrene in a reaction medium comprising a modified 1,2-epoxy resin.  The epoxy resin is modified by combining a portion of its 1,2-epoxy groups with epoxy-reactive groups of an ethylenically unsaturated monomer, and reacting others of its 1,2-epoxy groups with a tertiary amine and with a preformed addition polymer containing carboxyl groups to form an ionic, resinous composition containing sufficient carboxyl groups to render the coating composition self-dispersible in water in neutralized form.

Title: Axial and radial supply bores in a scroll compressor
Inventor: SHIMIZU SHIGEMI
IPC: F04C29/02
Filed: 1988-09-07
Granted: 1994-06-14
Abstract: AXIAL AND RADIAL SUPPLY BORES IN A SCROLL COMPRESSOR   ABSTRACT OF THE DISCLOSURE       This invention discloses a lubricating mechanism of a hermeti-cally sealed scroll type compressor in which an inner chamber of a housing is kept at suction pressure. The compressor includes a drive shaft supported by bearings in inner blocks. The drive shaft is opera-tively linked to an orbiting scroll which orbits within a stationary scroll. A rotation prevention device prevents rotation of the orbiting scroll. The drive shaft includes an axial bore extending from an open end and terminating adjacent a forward bearing. A pin extends from the end of the drive shaft to the orbital scroll. A passage links the axial bore to an opening at the end of the pin facing the orbital scroll radial bores are provided near the terminal end of the axial bore and at the rearward end of the axial bore near a rearward bearing. The radial bores link the axial bore to a suction chamber of the compres-sor to allow lubricating oil to lubricate the bearings. The narrow pas-sages allows lubrication of the rotation prevention mechanism. In a second embodiment the suction chamber is divided into two sections by a partition wall. An inclined passage links the two sections to allow the lubricating oil to flow.
Patent CA-1332269-C (CA)
Inventor: DHINGRA YOG R
IPC: B01J20/285

Granted: 1994-10-11
Abstract: ABSTRACT       This invention is a process for the chromato-graphic separation of a fluid mixture in which the mix-ture is contacted with an ion-exchange resin, eluted through the resin under conditions such that the rate of passage of one component of the mixture through the resin bed is retarded relative to the rate of passage of a second component of the mixture, and a first product stream rich in said first component and a second product stream rich in said second component are recovered.  The invention involves the use of an ion--exchange resin made from a copolymer which is prepared in a multi-stage polymerization process.  The use of this resin is found to provide fast separation kinetics and increases the overall speed and efficiency of the separation.  This invention is particularly suited for fructose/glucose separations in the preparation of high fructose corn syrup.

Title: System for transmitting low frequency tones through a  digital loop carrier system
Inventor: DILLON PHILIP L
IPC: H04M11/06
Filed: 1989-02-03
Granted: 1992-04-28
Abstract: Abstract A  system  for  use in a digital loop carrier (DLC) which  allows low frequency (sub-audible) tones such as those  used  with  alarm systems to be transmitted from one  end  of  the  DLC to the other end even though the DLC  has  been designed to reject signals below 200 Hz. The  system may be added to an already installed DLC or included  with  the  DLC prior to installation.  At the end  of  the  DLC  from  which  the  low  tone is to be transmitted,  the  system controls the amplitude of the tone  so that it can be encoded for transmission within a  predetermined  window.    The  DLC  allows  such low frequencies  to be transmitted through the window while still  rejecting  60  Hz  signals  (and its lower order harmonics).    The  controlled low  tone and the voice signals  are  combined  for  transmission  to the other end.    At  the  other  end,  the  decoded  low tone is amplified  by  the  system and then recombined with the decoded voice signals for use therein.

Abstract: DISK HARROW STANDARD          FOR SUPPORT BEAMS OF DIFFERENT CROSS SECTIONS          Abstract of the Disclosure A disk bearing standard which may be utilized with support tubes of different cross sections by simply changing a low cost U-bolt which clamps the standard to the tube.  The standard includes front and lower locating surfaces formed at an angle of ninety degrees with respect to each other.  A bolt-receiving member angles upwardly from the forward surface at an angle of about forty-five degrees and receives an angled leg of the U-bolt.  The rear leg of the U-bolt extends downwardly through an elongated slot at the aft end of the lower locating surface.          The size of the U-bolt is selected according to the size of the mounting tube, and the U-bolt clamps the standard in two planes perpendicular to each other to prevent misalignment of the standard when loads are applied.  A rearwardly extending appendage provides a scraper tube mounting which is fixed with respect to the center line of the disk blades regardless of the selected size of the mounting tube.

Title: Tortilla press apparatus and methods
Inventor: RUBIO MANUEL J
IPC: A21C11/00
Filed: 1989-05-08
Granted: 1993-06-15
Abstract: ABSTRACT OF INVENTION            This invention relates to apparatus and methods for producing formed articles such as tortillas. Embodiments include apparatus comprising a non-sticking, heat tolerant, endless conveyor belt moving at desired constant speeds to position tortilla dough balls between the heated platens of a tortilla press. The press is moveable in the direction of the path of travel of the belt at the same speed as the belt when the platens are in their closed position with the dough balls squeezed between them. Thereafter, the press may be opened sufficiently for the upper platen to disengage the flattened dough and then slowed, stopped and moved counter-directionally to the direction of travel of the belt. At a pre-determined position, the press is again stopped and  reversed to cause it to travel again in the direction of travel of the belt. The platens then close on the dough balls when the press has reached the same speed of travel as the belt, repeating the pressing cycle on the group of doughballs next to the last batch of tortillas that was formed by the press.

Abstract: System and method for disposing of liquid borne organic waste materials.  The waste material is passed through a compost bed containing a fecal material which treats the organic waste biologically, removes liquid from the waste by adsorption and absorption, and filters out colloidal particles.  Any waste material which remains after passing through the compost bed is passed through a charcoal filter bed, then recycled through the compost and charcoal.  Warm air is passed through the charcoal and the compost to provide aeration for the composting process and removes the adsorbed and absorbed water from these beds.  The air is then passed through another charcoal filter bed and, in a disposal system, discharged as effluvia.  In a recycling system, the air from the second filter bed is condensed, and the condensate is returned to the system which generated the waste material or to another system such as a processing plant in which the condensate can be utilized before being discharged as effluvia.

Granted: 1992-11-24
Abstract: ABSTRACT    An adaptive interference canceller for use in a dual polarized radar system for receiving cross-polar and like-polar signals and generating an output signal corresponding to the received cross-polar signal with a like-polar interfering component cancelled therefrom.  A modified adaptive filter is provided with a self-adjusting impulse response conforming to a least means square adjustment cancelling the influence of the like-polar signal, which is generally much stronger on the cross-polar signal.  The resulting output has a high target-to-clutter ratio and therefor a high probability of detection.
