Title: System and method for reducing timing channels in digital data processing system
Inventor: HU WEI-MING
IPC: G06F21/72
Filed: 1990-09-17
Abstract: ABSTRACT OF THE DISCLOSURE A digital computer system for processing at least one process, said process generating operational requests for enabling selected operations. The computer sys-tem comprises a timer portion for generating two series of unpredictable timing in-dications. An operational processor portion is responsive to the timing indications from said timer and the operational requests for initiating operations enabled by the operational requests in response to one of the series of timing indications. The op-erational processor communicates with the processes regarding operations enabledwith respective operational requests in response to the second series of timing in-dications. Since the timings of the operations by the operational processor are dis-tinct from the timings of the communications between the operational processor and the process, the process is unable to determine timing information from the opera-tions performed by the operational processor in response to the operational re-quests, thereby ensuring that the process will be unable to use the timings of the op-erations by the operational processor to determine timing intervals. In another aspect, the digital computer system includes a system timing generator for generat-ing a system timing value that provides timing information. The system timing gen-erator updates the system timing value at unpredictable intervals, but so that the sys-tem timing value provides timing information that is accurate as of the time of up-date. When the process requests the system timing value, the system timing genera-tor supplies only a selected high-order portion of the system timing value, alsoensuring that the process only has imprecise timing information. Since the process has access to only an imprecise system timing value, and since it is unable to use ex-ternal operations, by the operational processor, for timing information, the band-width of any covert timing channels is reduced accordingly.

Title: Beverage carbonating, cooling and dispensing system
Inventor: PARNET DIETMAR
IPC: B01F13/00
Filed: 1991-01-29
Abstract: ABSTRACT OF THE DISCLOSURE BEVERAGE CARBONATING, COOLING AND DISPENSING SYSTEM           A method and device is provided for carbonating water or a beverage with a minimum of carbon dioxide gas and operating steps.  A temporary connection of a regu-lated gas supply to a container tank is used for the period of time required to carbonate and saturate the water or beverage.   After the liquid is saturated with the gas and carbonated,  the gas supply hose is discon-nected.  The size of the container tank is restricted to the overall weight of the combined unit if it is to be used on a portable basis.  Larger amounts of liquid can be carbonated with this method, if the carbonating and dispensing set up is in a stationary, permanent location. The portable container tank is cooled by ice packs or cooling coils and air contact with the tank is kept to a minimum by providing an insulating carry container which encloses  the container  tank  and cooling means.   The internal  gas  pressure  is  used  for  dispensing  of  the liquid and the container tank is recharged, repressurized if it should become necessary for the discharging of all the liquid.

Abstract: 2059667 9102914 PCTABS00003 A stop valve assembly comprises two closure members one for stopping substantive gas or liquid flow and the other to prevent leakage along a spindle section (33). Each member possesses a closure element in the form of a rigid disc-like member (9 or 34) of accurately predetermined thickness lying in a recess (1 or 3) formed round the end opening of a duct or around the spindle section and having exactly the same depth as the thickness of the disc. Over the disc outer surface (11), and the end face around the recess is located a flat annular deformable seal member (14, 64); this can be secured at in relation to the disc member, so as to travel with the disc member (9) as a stop valve, or can be secured against the said face around the recess so as to define an antileakage spindle seal. Since no deformed seal is used and since no packing is used in the screw spindle mechanism, high actuating force is unnecessary. The assembly can be operated with a minimum of force to maintain pressures of hundreds or even thousands of pounds per square inch.

Abstract: Chlorobenzenes present in PCBs as viscosity reducing diluents can be largely removed from the PCBs by fractional distillation without carry over of PCBs into the chlorobenzene rich distillate.  The PCB rich bottoms can be economically destroyed using mixture with sodium dispersion under conditions of temperature, concentration and stirring which result in autocatalytic reaction. Sodium dispersion can be measured for dispensing into the reaction by accumulation under a pressurized gas space in a measuring vessel of predetermined volume until a predetermined pressure is attained.  The pressurized gas is then employed to expel the dispersion from the measuring vessel into the reactor.

Topologies are generated in which nodes are not always connected when their addresses differ  in  a  single  digit.   A  new  variable  d  is introduced,  the  purpose  of  which  is  to  control  the overall density of the network by controlling the number of intermediate arc connections within the rings of the network.
