Abstract: FASTENING APPARATUS AND METHOD FOR ASSEMBLING SAME       Abstract of the Disclosure A fastening apparatus and method for assembling same.  The fastener includes a shaft having a groove.  A second member, such as a collar, is received coaxially over and surrounding the shaft area including the groove.  A deformable retainer, received between the collar and shaft, secures the collar on the shaft and is bent inwardly into the groove by an internal shoulder on the collar when inserted between the collar and shaft.  The deformable retainer may be integrally and detachably formed with the collar.  The method includes positioning the second member or collar, and inserting and deforming the retainer between the shaft and collar.  The apparatus may be used to secure parts of bearing assemblies and retain bearing shields on such assemblies, in chain pin assemblies to form chains for conveyors or other applications, and for general fastening purposes.          A eccentrically positioned interlock for pre-venting rotation between the inner race of a conveyor wheel assembly and support member supporting the wheel assembly is also included in the invention.

Abstract: ABSTRACT The system for controlling the temperature of a room, which comprises at least one duct provided in a surface of the room, especially in the floor, and at least one temperature-controlling device extending in this duct whereby the air can be circulated through this duct, provides for at least one baffle in the duct which deflects or diverts the air from its main direction of flow defined by the connection of the intake opening with the discharge opening.  The duct can be limited on the side facing the room by a covering made of heat-conducting or heat-retaining material.  In a particularly suitable embodiment the temperature-controlling device is disposed in the duct in the form of a cable or hose; its outside diameter - or the outside diameter of a heat-conducting plate which preferably encompasses the device at least partly and which is in particular at least partially black - is slightly larger than the distance between the alignments of the baffles.

Abstract: INK SUPPLY SYSTEM FOR                  INK JET PRINTING APPARATUS     Abstract of the Invention A recoverable ink supply system, comprising both method and apparatus, includes a primary reservoir which is connected by suitable fluid conduit to a prime, or primary, pump.  The prime pump transfers the liquid ink from the primary reservoir to an intermediate reservoir at an increased pressure causing a lower pressure condition in the sealed primary reservoir and a higher pressure condition in the sealed intermediate reservoir.  Secondary, or metering pumps, receive pressurized ink from the intermediate reservoir after it is filtered at the reservoir outlet, and supply metered, higher pressure ink through combined filter/pressure fluctuation dampers to associated on/off control valves.  The control valves permit the flow of the pressurized ink into the print heads wherefrom the ink is discharged at a controlled uniform velocity.          According to known print head technology, a uniform series of ink drops is discharged from the print heads which are either deflected to a recording medium to produce characters or collected by a catcher for recycling to the primary reservoir.          Ink recycled to the primary reservoir contains entrapped air, or gas, and the major portion of the entrapped gas is drawn out of the ink in the low pressure reservoir.  The remaining gas, both dissolved and undissolved, is carried to the intermediate reservoir wherein the remaining undissolved gases are absorbed in the ink solution due to the high pressure therein.  This absorption phenomenon stabilizes the ink and, this stabilized ink is then supplied to the metering pumps before delivery to the print heads.

Abstract: METHOD AND APPARATUS FOR  IDENTIFYING FAULTY COMMUNICATIONS CIRCUITS            Abstract A method for detecting defective communications circuits in a telecommunications system.  Communications circuits are arranged in groups according to destination. Unacknowledged communications are counted for each group. A group whose incidence of such unacknowledged communications is especially high is likely to contain one or more defective communication circuits.  More detailed measurements, including a count of attempts to use each member of such a group, are then taken to identify individual defective communication circuits.  A communication circuit having an especially high count of attempts to use is likely to be defective.

Abstract: ABSTRACT : Speech analysis system.     Speech analysis system in which segments of speech are ana-lyzed. For the voiced/unvoiced decision use is made of the average magni-tude or waveform intensity of successive speech segments. Basically a voiced decision is made when the waveform intensity increases monotonically over several segments by more than a given factor. An unvoiced decision is made if the waveform intensity drops below a given fraction of the maximum waveform intensity in the current voiced period. Refinements in the decisions are made by the use of fixed and adaptive thresholds.            Used in vocoders. Figure 1.
