Title: Atmospheric pre-steaming chip bin vacuum and pressure relief device
Inventor: WESTON JOHN D
IPC: D21C1/02
Filed: 1992-04-16
Abstract: The proper pressure conditions are maintained within an atmospheric pre-steaming chips bin used in the production of paper pulp. Extending upwardly from the top of the chips bin is a vertical section of conduit, an elbow section, and a horizontal section. A door guide with a door opening in it is disposed in the horizontal section and precludes passage of gas through the horizontal section except through the door opening. A pivot pin mounts a door at its top so that it normally assumes a vertical orientation closing off the opening, and it is adjustably biased into that orientation by a counterweight mechanism. The counterweight includes weight discs which mount on a vertical section of rod having external screw threads, and a horizontal section of rod is connected by a flange to a flange of the pivot pin. The door remains closed unless the pressure differential between the chips bin and the surrounding environment is greater than about 2 psig, in which case gas may flow from the environment to the chips bin, or vice versa, to bring the pressure differential within the desired range.

Patent CA-2069015-A1 (CA)
Inventor: OTTO MARY R
IPC: H04Q3/66
Filed: 1992-05-20
Abstract: This invention relates to apparatus and methods for sharing traffic among a plurality of ACD sites serving a customer. Each ACD site has a main queue for storing incoming calls to that ACD, and a group of overflow queues forstoring calls rerouted from one of the other ACD sites. Before rerouting a call to an alternate site, the overflow queue for that site is checked; if it has an excessive number of entries, calls will not be rerouted to that alternate site. If one of the ACD sites is not appropriately equipped with overflow queues for different sites and an appropriate program for steering calls, that ACD site can route its overflow traffic via one of the ACD sites, designated as a mother node, for distributing overflowfrom the one site to others.

Title: Process for adjusting the tension in a tape
Inventor: SCHANDL HARTMUT
IPC: G11B15/665
Filed: 1990-11-22
Abstract: Hannover, Dec. 18, 1989 ABSTRACT   1.       Method for the adjustment of the tape tension.   2.1    With known video recorders the tape tension sensor lever is lifted off the magnetic tape for the change-over to the backward search mode and the tape tension is predetermined by a firmly pre-adjusted slip coupling in this mode of operation.  It is the object of the invention to maintain the last adjusted tape tension as well as the tape position relative to the adjacent magnetic heads throughout a change-over from the reproduction mode to the backward search mode and, at the same time, to control the tape tension in the backward search mode via the tape tension sensor lever.   2.2      The tape tension sensor lever is arrested in its last obtained position by a controllable catch lever during the change of direction into the backward search mode in such a manner that the lock is lifted (terminated) at the start of the backward mode through increased tape tension. Further control of the tape tension happens through a slip coupling, whose effects are adjustable, which is controlled by means of an electro-mechanical converter dependent on the position of the tape tension sensor lever.   2.3  Magnetic tape recorder 3.

Abstract: A radio communication apparatus is tested by radio and optical test signals (RTS and OTS) simultaneously transmitted by a test transmitter.  Each test signal carries a test digital data signal.  The apparatus has a radio digital data recovering section for recovering the test digital data signal as a first digital data signal from the radio test signal.  An optical digital data recovering section recovers the test digital data signal as a second digital data signal from the optical test signal.  A comparing section produces a bit coincidence signal whenever corresponding bits between the first and the second digital data signals coincides with each other.  A counter counts up a count to an increased count in response to the bit coincidence signal during a predetermined time interval.  An indicator indicates the increased count as sensitivity of the apparatus.

Abstract: A retainer for securing and retaining a pre-hung door unit in a closed position relative to a door jamb. The retainer includes a shaped cylindrical plug configured to fit closely in the edge bore of the door. The plug is insertable into the edge bore through the face bore of the door and has lobes extending transversely to limit its entry into the edge bore.    The placement of the transverse lobes maximizes the length of the plug extending from the lobes which enables an end of the plug to extend beyond the door edge into a bore in the strike jamb of the door jamb when the door is closed relative to the door jamb.  A bolt extended through the back of the strike jamb and engaging the plug secures the plug in position and secures the door in a closed position relative to the door jamb.   The bolt may be tightened adequately to clamp the strike jamb to the door edge.  The bolt and the plug are provided with  double  lead  blunt  end threads  for  rapid  assembly  and disassembly. The plug has relieved sides for ease of moving the plug within the edge bore of the door which is a benefit for installing the plug and also is an aid to a door installer.  A cinch ring provided on the plug near the extended lobes prevents lateral movement of the plug in the edge bore.  The configuration of the plug accommodates both circular and rectangular bores that are normally provided in the strike jamb of the door jamb.

Abstract: For the sliding transport of glowing material, which can be set down on at least one sliding shoe (6), through the furnace, the sliding shoe (6) has, for lateral guidance on the rails (5), an approximately U-shaped cross-section with downwardly projecting legs (10). On the side of the sliding shoe (6) and/or of the rail (5) facing the sliding plane, special sliding elements (12, 12a, 12b) are situated, which are designed in such a manner that wear and friction during movement of the sliding shoes are as low as possible. To this end, the sliding elements (12) have sliding surfaces, the lateral surfaces of which are rounded and/or downwardly inclined and/or the circumferential edges of which are assigned to one another at obtuse angles or - at least partially - have a circular shape. These conditions are present e.g. in the case of sliding elements with polygonal or circular surfaces, which can be arranged in one or more rows as well as in honeycomb structures. As in this case essential edges run obliquely in relation to the direction of movement and moreover no acute edge angle which is at risk of breakage is present, disturbances - e.g. on running over rail joints - do not have an effect simultaneously on the entire edge so that edge breakages can to a great extent be avoided. Provided between sliding-shoe web and glowing material support is a flowthrough duct, through which additional hot air is blown onto the points of the glowing material which are shielded from the main flow by rail (5) and sliding shoe (6).

Filed: 1993-01-05
Abstract: ABSTRACT OF THE DISCLOSURE An improved circular saw blade is rotatable in a guard casing having tree receiving vertically aligned openings in its upper and lower plates.  The blade has a peripheral surface formed in part by a series of replaceable circumferentially spaced teeth with transverse cutting edges positioned to rotate about a predetermined first radius.  The blade also has a series of circumferentially spaced, generally radially projecting backer tooth mounts for receiving the rear surfaces of the teeth.  The mounts have sloped peripheral surfaces lying radially inside the first radius of rotation and have rear surfaces generally parallel to the mount front surfaces.  The saw further has generally tangentially projecting finger-like guides in a guide region spaced circumferentially forwardly from each tooth to provide a radially extending chip passing slot between each tooth and guide and the guides have peripheral surfaces positioned to rotate radially inside the first arc of rotation about a second arc of rotation.  Rearwardly and outwardly extending trailing surfaces extending substantially perpendicularly from the rear surfaces of the mounts lead from the tooth mounts to the guide peripheral surfaces to form the peripheral surfaces of the saw between the tooth mounts and guides.  A series of loop shaped openings join to the chip passing slots and have marginal radially angular chip deflecting walls extending at an angle in a forward direction.  Fasteners extend chordally through the mounts from the rear of the mounts into the teeth to releasably secure them to the mounts.
