Abstract: ABSTRACT           Sintered articles made from binary compositions of silicon carbide and titanium diboride are described.  The articles may be prepared by initially mixing finely-divided silicon carbide, carbon or a carbon source material, a densification or sintering aid, and finely-divided titanium diboride, forming the mixture into a desired shape and subsequently heating at temperatures sufficiently high to form a sintered ceramic article of silicon carbide and titanium diboride.  When the present sintered ceramic articles contain high amounts of titanium diboride, generally between about 65 and about 95 percent, and more preferably, between about 80 and about 95 percent, by weight, they are quite electrically conductive, generally having less than 0.2 ohm-cm electrical resistivity, and are useful as electrical ignitors. Such articles are also extremely resistant to corrosion by molten aluminum and aluminum alloys; thus, they are aptly suited to use as electrodes in aluminum refining processes.  When the present sintered ceramic articles contain high amounts of silicon carbide, generally between about 50 and about 95 percent by weight, they are characterized by high densities and high strengths, typically having MOR above 50,000 psi, and an extraordinary resistance to thermal shock.  Such articles are particularly useful in the fabrication of diesel engine precombustion chambers and as honeycomb structures, such as those utilized in automobile emission control units.

Abstract: ABSTRACT OF THE DISCLOSURE Improved flexible waterproofing membranes of the pre-formed pressure-sensitive or self-adhesive bituminous type particularly useful in roofing are described.  The membranes are in the form of factory-manufactured, flexible, sheet-like laminates employing a comparatively thin layer of metal film or foil positioned (a) beneath a support layer of synthetic polymer film and (b) above a layer of waterproofing self-adhesive bituminous composition such as rubberized asphalt.  The metal film imparts a number of desired properties to the laminate such as fire-resistance, handling, etc.  The upper polymeric support film pro-tects the metal film and provides, inter alia, strength, puncture-resistance, and additional waterproofing properties.  In one preferred embodiment, the upper polymeric film layer is a film having good weatherability characteristics.  The upper polymer film may also desirably be a film having a higher linear thermal expansion coefficient than the underlying metal film layer in order that the edges of the applied laminate when exposed to e.g. solar heating and subsequent cooling turn downward towards the substrate to be waterproofed resulting in improved sealability.  Additionally, further layers of e.g. protective films and coatings may be applied to the laminates.

Abstract: DISPERSION EQUALIZED RING LASER GYROSCOPE        Abstract A ring laser gyroscope system uses a non-planar path and non-depolarizing Faraday bias means to achieve four-frequency differential operation.  The use of the non-planar path elimi-nates the crystal rotator normally used to provide reciprocal bias and therefore eliminates scattering surfaces and a major cause of thermal sensitivity.  The non-depolarizing Faraday means, such as a thin glass slab having a component of magnetic field along the optic axis of the laser, is used to reduce the corresponding thermal sensitivity of the traditional Faraday bias element normally implemented by a crystal such as quartz.      Eliminating these major sources of drift then allows higher-order sources of drift to be corrected.  Zeeman  splitting of the laser gain medium is used to provide an equal amount of dispersion to each of the two counter-travelling waves of each wave pair, thus eliminating small amounts of drift due to the different phase shifts produced in the propagating waves by the gain medium.

Abstract: ABSTRACT The invention is an information handling apparatus of the type compri-sing a memory, a circuit for designating a memory location where the instruction to be read is stored, a circuit for reading the designated instruction out of the memory, a circuit for detecting that a predetermined instruction has been read out and generating a detection signal and a circuit for inhibiting execu-tion of at least one subsequently scheduled instruction in response to the detection signal.  According to prior techniques up to several machine cycles of time are required to read out the instruction to be inhibited and the same time is required to exchange the instruction with a non-operation instruction. According to the invention a circuit is provided for preparing in a short period of time an address for a next new instruction of the inhibited instruction. Thus the invention replaces the address of an instruction which is not to be executed with the address of the next instruction to be executed.  The pro-cessing time is thereby greatly shortened.

Abstract: ABSTRACT         PREPARATION OF CHLOROTRICLUOROETHYLENE       AND TRIFLUOROETHYLENE 1,1,2-trichloro-1,2,2-trifluoroethane is dechlorinated with hydrogen to produce chlorotrifluoro-ethylene and trifluoroethylene.  Chlorotrifluoroethylene may be further dechlorinated to trifluoroethylene.  Tri-fluoroethylene may then be hydrofluorinated with or without the use of catalyst to produce tetrafluoroethane and, particularly, assymmetrical tetrafluoroethane. Tetrafluoroethane produced by this process can be purified for refrigeration and other applications more easily than tetrafluoroethane produced by other processes since impurities which form azeotropes with tetrafluoroethane are minimized.  A catalyst for the low temperature dechlorination of trichlorotrifluoroethane and of chlorotrifluoroethylene is a platinum-group metal such as palladiurn on an alkali magnesium fluoride support.  Catalysts for the high temperature dechlorination of trichlorotrifluoroethane are alkali magnesium fluorides alone or coated with iron, copper or nickel.  These catalyst can be reactivated with oxygen or air at elevated temperatures.  The products chlorotrirluoroethylene and trifluoroethylene are useful as monomers while tetrafluoroethane is useful as a refrigerant.

Abstract: Abstract of the Disclosure Tobacco which has been increased in filling power by a conventional tobacco expansion process can be further increased in filling power by a post expansion heat treat-ment.  The post expansion heat treatment comprises contacting the expanded tobacco produced by a conventional expansion process with a gaseous medium, such as air and/or steam, at a temperature of from about 200°F to about 450°F. The post expansion heat treatment is preferably conducted at a lower temperature than the temperature of the heating step of the expansion process, and thus can be more easily controlled, while providing an additional increase in filling power.      The product of the post expansion heat treatment process of this invention has been found to be as acceptable in subjec-tive smoking characteristics as the expanded tobacco which is treated by the process.

Abstract: SIMPLIFIED MAINTENANCE ELECTROCOAGULATOR        ABSTRACT OF THE DISCLOSURE     An improved method and apparatus for electrocoagulating waste water or fluids to remove colloidal suspensions therein is described.  The apparatus includes at least one module having a plurality of closely spaced, flat electrodes defining a plurality of flow paths therebetween. Each pair of electrodes is separately mounted in the module and each electrode has a separate connection to a source of alternating current.  Each pair may then be rapidly removed from the module for inspection, maintenance, or replacement or alternate  pairs may be removed increasing the distance between the electrodes, if desired.  The method allows the utilization of a fluidized bed of graphite particles to scrub the electrode faces, and it also permits the repelling forces on suspended solids to be broken on a continuous basis at relatively low current density in a collapsing field of alternating current.  A relatively high volume flow rate of waste water or fluids may be rapidly and economically treated to remove contaiminants so that the treated waste water or fluid is suitable for disposal.

Abstract: ABSTRACT OF THE INVENTION           An actuator mechanism for detecting the presence of the piston or other movable element of a fluid cylinder for reversing switch purposes and the like is disposed in the end cap of the cylinder and is engaged by the cushion spear on the piston to provide transverse linear motion for actuation of a microswitch.  The mechanism consists of a slender rod supported for movement transverse to the motion of the piston, the rod having a shoe at its lower end which receives a plunger, the latter passing through a bore in the end cap and adapted to be cammed upwardly by engagement with the cushion spear.  The shoe and plunger are spring-biased toward the piston and the upward movement against the bias serves to actuate a microswitch external of the end cap to signal the presence of the piston.  In a design suitable for  different size  cylinders,  the  plunger  is formed of square stock of appropriate length.   Rounded corners  of  the  plunger  stock  at  both  ends  provide  a slidable supportive engagement in a bore in the adapter shoe and in the end cap bore and assure fluid communication through the lower bore to prevent pressure-induced, false actuations.

Abstract: ABSTRACT OF THE DISCLOSURE       This invention relates to a method of enhancing oil recovery from an underground reservoir containing oil. A gas which is miscible with oil at the temperature and pressure of injection is injected into the reservoir to displace oil.  Injection is carried out in such a way as to make sure that a mixing zone is formed in the reservoir such      that each fluid introduced is miscible with the fluid immediately preceding it and the fluid immediately following it.  This is done by injecting small slugs of fluid miscible with, but different in composition from, the fluid adjacent to the perforated zone of the well.  The injection of each slug is followed by a shut-in period to permit a mixing zone to establish itself.
