Abstract: TELECOMMUNICATIONS INTERFACE WITH PROTECTOR MODULES          Abstract of the Disclosure An interface for connection between incoming telephone lines and the customers equipment has a base for mounting on a support surface, with terminals for connection of incoming telephone lines and one or more plug-in positions for plug-in modules.          Protectors are positioned in the modules.  Each module has a modular jack.  An intermediate cover fits over and is attached to the base, covering also the modules but with one or more apertures for access to the jack or jacks.  The conductors from the customers equipment either terminate in modular plugs which insert directly into the jacks or terminate in spade terminals which are connected to terminals on the intermediate cover.  In the latter case, a short interconnect cable connects at one end to these terminals and at the other end has a modular plug for insertion into a jack.  An outer cover extends over the intermediate cover and the modular jack or jacks.                                - i -

Abstract: A method for the production of composite articles by pultrusion is provided wherein the articles comprise thermotropic liquid crystalline polymers and reinforcing fibers. The liquid crystalline polymers employed exhibit physical characteristics such that the negative slope of a dynamic viscosity-frequency curve (as defined) is less than about 0.35. The use of polymers having such rheological characteristics enables a composite material to be produced by pultrusion in which the polymer is uniformly dispersed among the reinforcing fibers.

Abstract: Abstract Fault Testing A Clock Distribution Network A method and apparatus for fault testing a clock distribution  network which  provides  a  plurality  of clock signal lines to the logic networks which comprise a data processor.  The fault testing apparatus includes a decoder for selecting one of the clock signal lines to be tested, and a test latch which is clocked by the selected clock signal line.  The selected clock signal line is tested by setting the test latch to a first logic  value  (e.g.,  binary  ZERO) and  maintaining  a second logic value (e.g., binary ONE) at the test latch input.  If the second logic value is stored in the test latch when the clock distribution network is inhibited, then a stuck-on fault is indicated for the selected clock signal line.  If the second logic value fails to be stored in the test latch when the clock distribution network is enabled, then a stuck-off fault is indicated for the selected clock signal line.  Each clock signal line in the clock distribution network may be tested in this manner.

Abstract: ABSTRACT OF THE DISCLOSURE          A rotary drill bit, for use in subsurface formations, comprises a bit body, a passageway for drilling fluid within the body, communicating with nozzles in the external surface of the body, preform cutting elements mounted on the body for cutting or abrading the formation, and a number of elongate fences upstanding from the external surface of the body to control the flow of fluid from said nozzles and past cutting elements.  Each fence includes a plurality of resiliently deformable elements disposed adjacent one another in a direction across the width of the fence, for example being in the form of a brush having metal bristles, so that, in use, the free elongate edge of the fence is urged resiliently into contact with the surface of the formation being cut or abraded by the cutting elements.  Since each fence is resiliently deformable it will at all times firmly engage the formation to provide an effective seal, regardless of variations in depth of cut of the cutting elements.

Abstract: ABSTRACT   A master cylinder employed in connection with a fluid actuated motor vehicle clutch system. The master cylinder includes an internal reservoir formed by a portion of the sane cylindrical housing which makes up the clutch actuating working chamber. A plug is provided within the cylindrical housing to divide the housing into two sections, a working chamber and a reservoir chamber. The plug further includes a check valve system which permits fluid to flow into and out of the working chamber from the reservoir as the fluid capacity of the associated hydraulic circuit changes. Flow into and out of the reservoir is permitted to occur only when an externally applied load to the master cylinder is released. The reservoir chamber includes a slidable piston and a low spring constant helical spring which biases the reservoir plunger to provide a slight hydrostatic pressure for the fluid contained by the reservoir, thereby preventing the ingestion of air or contaminants. In an embodiment of the invention, the fluid in the reservoir chamber may be initially pressurized to a greater than atmospheric pressure so as to give a small degree of boost to the system. This design configuration eliminates the requirement of providing an externally mounted reservoir or a reservoir which is mounted above the working chamber such that fluid therein is gravity fed into the working chamber. This design also permits the use of manufacturing techniques such as deep drawing of metal to construct the entire master cylinder and reservoir from a single tube structure.

Abstract: COMMUNICATION SYSTEM HAVING DYNAMICALLY      ASSIGNED STATION SET BUTTONS            Abstract There is disclosed a communication system and operating method wherein the manner in which all telephone calls are displayed at a station set allows uniform user operations to originate and terminate those calls.  This is accomplished by having all calls dynamically assigned to the same set of general call appearances (buttons on a multibutton station set).  There are no call appearances that are dedicated to specific call types.  This allows the station set user to perform the same set of operations on all calls by using the same sequence of physical operations independent of the type of call.  Additionally, the system may reserve one call appearance button at a station set for special use.

Abstract: Hollow microspheres made from dispersed particle film forming compositions comprising dispersed particles, a binder, a film stabilizing agent, a dispersing agent and a continuous liquid phase are described.          Porous and non-porous hollow microspheres can be made. The hollow microspheres can be caused to have walls with voids which are interconnected to each other and to the inner and outer wall surfaces, and can be used as membrane substrates in selective separation processes and in biotech processes. The hollow microspheres can be used as supports for catalysts and as enclosures for catalysts, adsorbents and absorbents. The hollow microspheres can also be used as filler materials and as proppants for increasing gas recovery from gas wells.     The hollow microspheres are made by a process which comprises forming a film of a dispersed particle film forming composition across a coaxial blowing nozzle, applying a blowing gas at a positive pressure on the inner surface of the dispersed particle composition film to blow the film and form an elongated cylinder shaped film of the dispersed particle composition. The cylinder shaped film is initially closed at its outer end, and as the cylinder shaped film progresses away from the coaxial nozzle, the film closes at its inner end, prior to the beginning of the formation of the next cylinder shaped film at the coaxial nozzle. The hollow dispersed particle composition microspheres are individually formed as they emerge from the coaxial nozzle. The blown microspheres form substantially spherical hardened hollow green microspheres.     The hollow microspheres can be blown into warm or hot ambient air to rapidly remove a portion of the continuous phase and harden the microspheres. Where a thermoplastic binder is used, the microspheres can be blown into cool or cold ambient air to rapidly cool and harden the microspheres. Where a photopolymerizable binder is used, the hollow microspheres can be subjected to ultraviolet light to rapidly polymerize the binder and harden the hollow microspheres.     The hollow microsphere can be made from dispersed ceramic particles, glass particles, metal particles, metal glass particles and plastic particles, and mixtures thereof. The dispersed particles can be 0.005 to 60 microns in size.     The hardened hollow green microspheres obtained from the microsphere blowing step can be heated at elevated temperatures to remove the continuous liquid phase and to sinter the dispersed particles to form strong hollow porous microspheres. The hollow porous microspheres can be treated with semipermeable membrane forming materials to make them non-porous and suitable for use in selective separation processes and in biotech processes, or the microspheres can be impregnated with liquids or gels and used in controlled release and membrane processes.
