Granted: 1992-08-18
Abstract: ABSTRACT   An automatic data plotting apparatus consists of three main parts: A processor (1); a serial and parallel interface (2); and a plotter (3).  The plotter is a flat-bed X-Y plotter.   The data processor (1) is programmed to handle one or more data inputs and instruct the plotter (3) to record information relating to the data inputs on a plot.   The processor (1) translates the incoming data into times, bearings, tracks and any other characteristics. A pause facility is provided to suspend plotting, the incoming data being stored in a data store while the pause facility is in operation and being recorded on the plot when the pause is discontinued. An automatic data plotting apparatus provides a focal point at which incoming information can be co-ordinated and displayed.   The displayed information can then be evaluated and/or stored for later analysis.

Abstract: A low calorie mayonnaise-like sauce prepared with ingredients consisting of vinegar, condiment, salt, water and egg, wherein thermally coagulated egg is dispersed in a heated, stirred mixture to form a sauce having a flavor similar to mayonnaise and being free of oil and other oily materials and wherein the sauce is in a semi-solid state with a fluidity equivalent to mayonnaise.  The sauce is prepared by: (a) stirring the egg with the vinegar added incrementally; (b) introducing the condiment after a uniform mixture has been obtained in (a); and (c) heating the mixture to a temperature of at least 60°C during a period of time sufficient to obtain a sauce in a semi-solid state, with a fluidity equivalent to mayonnaise and showing flavor like a mayonnaise sauce.  The present sauce compares favourably with mayonnaise but without including any oil or oily materials.

Granted: 1993-01-12
Abstract: FRAME SYNCHRONIZATION IN A NETWORK OF TIME MULTIPLEXED OPTICAL SPACE SWITCHES Abstract In an optical switching network, a master optical space switch is interconnected with remote slave equipments for switching block-multiplexed messages among the remote equipments. The master optical space switch responds to a frequency reference clock and steps through a sequence of states, or configurations, for establishing various routes among the remote equipments for appropriately routing the messages to correct destinations. The frequency reference clock also is distributed to the remote equipments. During one of the states per frame, each remote slave equipment transmits a distinct signature signal. All of the slave equipments are connected through the master optical space switch to return to themselves their own signals transmitted during that time slot. Each remote slave equipment compares the returned signal with the originally transmitted signature signal to determine how much the round trip delay has varied from a nominal value. Phase of a local control clock signal in the slave equipment is adjusted to counteract the variation of the round trip delay. Thus the operation of the slave equipment is adjusted into synchronization with the master optical space switch so that messages transmitted from the slave equipment arrive at the master optical space switch at the appropriate time with respect to the periodic reconfiguration of the master optical space switch.

Abstract: ABSTRACT The present invention is an improved process for the production of nitrogen and oxygen that uses a double distillation column arrangement. The improvement to the process is the recycling of at least a portion of the oxygen-enriched waste stream to the bottom of the high pressure column. As a result of this improvement, the process is capable of making a nitrogen product with high purity (e.g., 5 ppm oxygen product) at high pressures (e.g., 40 to 150 psia) while simultaneously producing high purity oxygen (e.g., 99.6% oxygen). Nitrogen is produced only from the high pressure column.
