摘要： A thermocouple vacuum gauge includes a first thermocouple element spaced below a second thermocouple element. The two thermocouple elements are electrically connected in series in a back-to-back manner by connecting together their respective negative ends. A pulse generator supplies a pulsing on-off current only to the first thermocouple element. During the off intervals, a switch connects the positive ends of both thermocouple elements to a voltage measuring and comparing circuit which measures a thermally generated voltage signal between the positive ends of the thermocouple elements and compares the measured voltage signal to a reference signal. The result of the comparison is used to vary the output current of the pulse generator so as to supply an amount of current to the first thermocouple element sufficient to cause the measured voltage signal to approach the reference signal. The amount of current supplied sufficient to cause the measured voltage signal to approach the reference signal is proportional to the amount of pressure or vacuum in an enclosure in which the thermocouples of the vacuum gauge are placed. A method for measuring pressure at partial vacuum which employs these features is also described.

摘要： A system and method for providing a control store arrangement in which a single memory having a plurality of memory locations can be used for storing sequences of microinstructions or scratch pad information. The number of storage locations defining the scratch pad area can be increased or decreased as required by assigning tag addresses to a desired number of scratch pad storage locations when the microinstruction routines are being assembled. In this manner, the locations defining the scratch pad areas can be tailored to the particular system operation to be performed. This eliminates the need for modifying the control store circuits to change the size of the control store scratch pad area.

摘要： A host system includes a microprogrammed processing unit which couples a foreign processing unit to the main memory of the host system. The microprogrammed processing unit also couples to an interface connected to the foreign processor. During operation, the host processor transfers a channel command to the microprogrammed processing unit which is operative under firmware control to perform the various control functions required for initiating a particular job. In this manner, the various parameters and information necessary to dispatch a job of the foreign processor is accomplished expeditiously under the firmware control in response to commands issued by the host processor.

摘要： The instant invention is a membrane useful for separating organic matter such as proteins from aqueous solutions which resists fouling and maintains a high flux during separation. The membrane is prepared by either drying a polysulfone composite membrane, or first treating a polysulfone composite membrane with aqueous methanol and then drying it. The membrane is then exposed to elemental fluorine in an inert gas in the substantial absence of oxygen at a temperature in the range of about -45.degree. to 70.degree. C. After fluorine treatment, the membrane is exposed to air. The fluorine content in the treatment mixture may be from 0.0125 to about 10 volume percent, preferably 0.025 to 2 volume percent. The fluorine treatment does not significantly alter the membrane pore size.

摘要： A control store included in a data processing system for storing microinstructions in a plurality of microinstructions storage locations is organized in two parts, an upper bank and a lower bank. The lower bank is directly addressed by a portion of the currently addressed control store word, whereas the upper bank is addressed by use of a multiplexer, with inputs thereto coupled from various logic elements. Apparatus is included to determine which part of the control store will be selected and to allow such determination at a time substantially after the addresses for the first and second parts have been received by the control store. In addition, the elements included in the upper bank are selected to have address propagation time sufficiently faster than the address propagation time of the lower bank to compensate for the additional logic propagation delay introduced by the multiplexer so that the contents of the addressed locations of the upper and lower banks are available for use by the system at substantially the same time.

摘要： A cold cathode ionization gauge includes a first and second electrode spaced apart and insulated from one another and having a common axis. A magnetic field generator surrounds the gauge and applies a non-time varying magnetic field along the common axis of the electrodes. The magnetic field generator includes at least one pair of opposed axially magnetized magnets adjacent each other. In one embodiment of the invention a non-magnetic annular spacer is placed between the opposed magnets. The magnet arrangement minimizes magnetic flux outside of the gauge while increasing the strength of the magnetic flux inside of the gauge. The magnetic arrangement also allows the gauge to be ignited in a very high vacuum, thereby extending the operating range of the gauge.
