Title: Electronic control cartridge and method of simulating light transmission patterns
Inventor: YASSINZADEH ZIA
IPC: G01N21/27
Filed: 1992-03-05
Abstract: ELECTRONIC CONTROL CARTRIDGE              AND METHOD OF SIMULATING LIGHT TRANSMISSION PATTERNS                ABSTRACT OF THE DISCLOSURE           The invention provides devices and methods for electronically simulating a standard absorbance value in an analytical instrument that measures absorbance of light in order to verify the correct operation of the instrument.  A liquid-crystal/-polarizing-filter combination located in the light pathway normally occupied by sample is used, along with sufficient voltage changes to selectively block and transmit light through the liquid crystal, thereby causing a light detector in the analytical instrument to read transmitted and blocked values of light. calculation then is used to determine whether proper operation of the instrument has occurred.  Different absorbance values, as well as different patterns of varying transmission (such as exponential decay), can be simulated by causing the liquid crystal to switch from absorbance to transmission (or vice versa) at different times.

Title: High activity slurry catalyst process
Inventor: LOPEZ JAIME
IPC: C10G45/18
Filed: 1991-04-26
Abstract: ABSTRACT OF THE DISCLOSURE           A high viscosity index lubricating oil is produced from heavy oils by using a high activity slurry catalyst process. The catalyst is produced by sulfiding aqueous Group VIB metal compounds to a dosage greater than 8 SCF hydrogen sulfide per pound of Group VIB metal.  The Group VIB metal can be promoted with Group VIII metals to enhance its activity.            High activity slurry catalysts for hydroprocessing heavy hydrocarbon oils are produced from Group VIB metal compounds by sulfiding an aqueous mixture of the metal compound with from greater than about 8 to about 14 SCF of hydrogen sulfide per pound of Group VIB metal.            The hydroprocessing of heavy oils is improved by the use of a high activity slurry catalyst prepared by sulfiding an aqueous Group VIB metal compound with a gas containing hydrogen sulfide to a dosage greater than 8 SCF of hydrogen sulfide per pound of Group VIB metal.  After introducing the slurry catalyst into the heavy oil, and subjecting the mixture to elevated temperatures and partial pressures of hydrogen, the mixture is treated in a fixed or ebullated bed of hydrodesulfurization/hydrodemetalation catalyst under hydroprocessing conditions.

Title: Offset conveyor
Inventor: FREEMAN ROSS A
IPC: B65H35/10
Filed: 1992-07-29
Abstract: ABSTRACT OF THE DISCLOSURE      Continuous business forms are detached and disposed in offset stacks.  Continuous forms being fed into a conventional detacher are sensed by a first optical sensor, and after detachment are conveyed by a roller conveyor away from the detacher in a first direction.  A guide rail is elongated in generally the first direction and the detached forms have an edge which engages the guide rail so that all the forms in a particular group are aligned when discharged from the conveyor into a stack.  The guide rail is mounted on balls, and by guide rods, for movement in opposite second and third directions, both generally perpendicular to the first direction, so as to change the position of the edge of detached forms in a subsequent group of forms so that consecutive stacks are offset from each other.  A second optical sensor at the discharge of the conveyor cooperates with the first sensor and a control mechanism to operate the detacher and solenoids for moving the guide rail between its different guiding positions to form offset stacks of business forms.

Patent CA-2100176-A1 (CA)
Inventor: DENNIS STEPHEN V
IPC: G06K15/00
Filed: 1993-07-09
Abstract: A resource oriented host computer-printer system is disclosed in which the host computer and printer share information and data processing duties. A system and method for analyzing the execution times for draw primitives allows the host computer to determine whether the printer will be able to render draw primitives in real-time. If the printer cannot render the draw primitives in real-time, the host computer may send the draw primitives to be pre-rendered by the printer. The rendering is accomplished in less than thirty seconds. The host computer can determine the execution times for the draw primitives and dynamically alter the timeout period accordingly. If the printer exceeds the determined execution time, the host computer generate a timeout error message. No false timeout error messages are generated by the host computer because the timeout period is related to the actual processing time required by the printer. If the printer is coupled to a network, the timeout period may be set to the maximum thirty second period because the host computer may not have continuous communication with the printer. The host computer will still not generate false timeout errors because the maximum timeout period is still related to the actual processing time required by the printer. The inventive system and method are applicable to any peripheral in which a timeout period is used. <IMAGE>

Abstract: ABSTRACT       An apparatus for forming container bodies utilizing a ram which is formed at least in part from a reinforced composite material  (e.g.,  rams having a combination of structural components with at least one component being formed from an appropriate metal(s) and another component being  formed  from the composite  material,  rams  formed entirely of the composite material).   In one embodiment, the ram is incorporated into a bodymaker for drawn and ironed  containers  and  includes  first  and  second  ram portions,  the  first  ram portion  being  formed  from  an appropriate metal, the second ram portion being formed from the composite material.  The first ram portion has first and   second   ends   with   an   interconnecting   portion therebetween such that a punch and ram drive assembly may be connected to such first and second ends, respectively.          The  second  ram portion  is  thus  positioned  about  the interconnecting portion to reduce the weight of the ram, as well  as  to  allow  for  an  improvement  of  the rigidity thereof.  Consequently, the speed at which the ram may be advanced through the ironing rings may be increased and the deflection of the ram when passing therethrough may be reduced to enhance the container body formation process.
