Abstract: APPARATUS FOR RECOVERY OF FLARED       CONDENSIBLE VAPORS              ABSTRACT OF THE DISCLOSURE      An apparatus for recovery of condensible vapors as components in waste gases which are to be flared, com-prising a flare system, including a flare gas line leading to a flare stack.  Inserted in the flare gas line is a gas-to-liquid heat exchanger, to cool the flare gases prior to passage to the stack.  The cooling is to a selected tem-perature, where condensible vapors in the waste gases, the dew points of which are above the selected temperature, will condense.  Means are provided for separating the con-densed vapors from the remaining flare gases.  Thermostatic means are provided for stopping the circulation of said cooling liquid whenever the ambient temperature drops below the selected temperature.

Abstract: ABSTRACT OF THE DISCLOSURE        An automatic pre-collation duplex copying apparatus (10, 20) and method in which original docu-ments having either an odd or even number of pages may be recirculatively copied (26) in reverse serial order yet provide properly collated output duplex copy sets. A simplex/duplex copying system is disclosed in which, when an odd number of document sheets are detected (29, 31, 100) in a first, non-copying, circulation of the document sheets, the copying of the last and sub-sequent alternate document sheets is inhibited during the first copying circulation, whereas if an even number of document sheets are detected, the copying of the second and subsequent alternate document sheets is inhibited during this first copying circulation, and these different copying sequences are reversed for the last copying circulation.  All document sheets are cop-ied during the intermediate circulations.  A compatible duplex/duplex copying system is also disclosed.

Abstract: Controlled Pressure Upstaging And Flow Reduction Abstract An improvement is disclosed in a hydraulic system having a variable displacement pump and being capable of delivering pressurized fluid from the pump to selectively engage at least three work circuits with a first of the circuits being normally operable up to a first pressure and a second of the circuits being normally operable up to a second and lower pressure.  The improvement comprises circuitry for selectively operating a third of the circuits at one of the first or second pressures or at an upstaged pressure which exceeds the first pressure and circuitry for reducing the displace-ment of the pump in response to the third circuit being operated at the upstaged pressure.  Such upstaged pres-sure is available in a controlled manner for working against particularly heavy loads.  Thus, a third and higher operating level is added to a system which already operates at at least two pressure levels.

Abstract: ABSTRACT         The traction device of the invention is for use with a vehicle wheel supported by lugs and having a tire.  The traction device has a base with openings for the reception of at least two but less than all, the lugs for supporting the base.  A plurality of spaced radial arms are supported by the base with each having an end adapted to extend beyond the outer periphery of the tire and protrude into an icy surface. Each of said ends is adapted to lie in a vertical plane adjacent to the outer side wall of the tire.  The end of each arm may advantageously be free to move in and out while being spring biased outwardly, be threadably attached to the arm for movement inwardly and outwardly, or be pivotally connected to the arm for movement into and out of an operative position. The said ends may extend different distances beyond the outer periphery of the tire.  Perferably, the base is secured on less than all of the lugs and has a bearing recess accommodating a nut on a lug to which the base is not secured.

Abstract: BACKUP POWER CIRCUIT FOR BIASING BIT LINES OF A          STATIC SEMICONDUCTOR MEMORY     ABSTRACT     A circuit is provided for biasing the bit lines of a static semiconductor memory when each of the cells (150) within the memory is being powered by a backup power source due to failure of the primary power source. The bit lines (52) connected to the cells within the array (50) are connected to transistors (54) which bias the bit lines (52) to a high voltage upon detection of failure of the primary power for the computer.  The bit lines (52) are maintained at a high voltage level to prevent discharge of a data storage node (156) through an access transistor (164) of a memory cell (150). Biasing of the bit lines (52) further prevents the integrated circuit substrate (150) from being driven excessively positive by capacitive coupling between the substrate (150) and the bit lines (52) when the primary power is restored to the circuit.

Said spring is arcuate and has a center of curvature situated at the side of the spring where the longitudinal side of the glass body is located.          A solder joint preferably of a eutectic metal connects the end of the spring remote from the bottom contact to a fusible element capable of interrupting short-circuit-like currents, i.e. a ribbon type fusible element having at least one point of reduced cross-section. The aforementioned spring and the fusible element enclose an angle of approximately 90 deg. and the end of the fusible ele-ment remote from said spring is conductively connected to a screw shell.

Abstract: ABSTRACT OF THE DISCLOSURE             Aliphatic, araliphatic or aromatic nitriles of the formula R-CN are obtained by reacting N-substituted formamides of the formula R-NHCHO with at least the stoichiometric quantity of an acylating agent (generally a carboxylic acid anhydride, such as acetic anhydride, or ketone) in the gas phase at temperature above 250°C, without using a catalyst.  The process is especially useful in the preparation of nitriles wherein the connecting carbon of R is a tertiary carbon atom.  The nitriles are important intermediate products, for example for the preparation of herbicides, surface-active agents and anti-corrosive agents.
