Abstract: COMMON CONTROL VARIABLE SHIFT REFRAME CIRCUIT          Abstract of the Disclosure The PCM encoded digital data groups transmitted to a switching office are respectively stored a frame at a time and then read out from store in the sequence such that a plurality of digital groups are multiplexed on to a common bus.  The disclosed reframe circuit utilizes common control circuitry to carry out, in the same time frame, a reframing operation for any and all of the multiplexed digital groups which are out-of-frame.  An "old" data store is used to store a given number of selected data bits, of each group, for two frames for framing comparison purposes.  A reframe comparator serves to compare, for each group, the output of the old data store with new data that is two frames later in time.  A suitability store is used to record, for each group, which of the compared data bits have had framing pattern violations.  A shift decoder determines how many digit shifts, if any, should be made by the reframer, based on the present set of comparisons and past suitabilities, in order to move to the next candidate for the framing bit.  Once the number of shifts is determined, the old data store, the suitability store and the write address logic of the receive data store for the out-of-frame digital group(s) are shifted by the determined number of digit shifts in preparation for the next set of data bit comparisons. The described operation is then repeated until the framing bit is recaptured.

Abstract: ABSTRACT OF THE DISCLOSURE           A modulator valve control assembly which is attached 'co an automatic transmission in an automotive vehicle to operate the modulator valve of the transmission in response to movement of the throttle linkage.  The modulator valve modulates the shift point at which the transmission changes from one mode to another.          The assembly includes a rectangular housing in which a bell crank lever is rotatably supported with one arm engaging a plunger which, in turn, is slidably disposed in a connection means for engaging the modulator valve of an automatic transmission.  The other arm of the bell crank is connected through a helically coiled spring to a flexible core element of a motion transmitting remote control assembly which includes a conduit or guide means for slidably supporting the core element.  The other end of the core element is attached to a threaded rod which, in turn, may be attached to the throttle linkage.  The housing includes a stop against which the bell crank lever may be positioned as the core element is placed in tension to place the helically coiled spring in compression.  The core element may move the bell crank against the stop and place the helically coiled spring in compression and a spacer is disposed between the guide or conduit and some portion of the core element to retain the core element in tension so that the assembly is preloaded.  The assembly is then placed in connection with a transmission whereby the modulator valve places a force upon the plunger of the modulator control assembly to move the bell crank away from the stop and thereafter the connection means is tightened to prevent relative motion between the modulator assembly and the transmission housing so that the assembly is preloaded.

Abstract: Abstract of the Disclosure An improved drive assembly includes a gerotor-type hydraulic motor having a housing connected to a frame.  An output member is rotatably mounted on a hollow spindle which is integrally formed with the motor housing.  Operation of the motor rotates an input shaft which is disposed within the spindle and is connected with the output member through a gear arrangement.  In order to tend to minimize the axial extent of the drive assembly, the gear arrange-ment is located inwardly of an outer end of the spindle.  The gear arrangement includes a central or sun gear which is disposed with-in the spindle.  A plurality of idler gears extend through openings formed in the spindle into engagement with the central gear.  These idler gears meshingly engage a ring gear which is fixedly connected with the output member. The gerotor-type hydraulic motor includes a wobble shaft which is connected with the input shaft to the central gear by a coupling member.  A stop member is movable in the spindle to disengage the input shaft from the central gear to deactivate the drive assembly.

Abstract: ABSTRACT A flexible vacuum cleaner hose is provided with a simple and inexpensive end fitting for use with various vacuum cleaner accessories and attachments.  The hose is a corrugated plastic, i.e., it has annular rings or corrugations formed therein.  Each section of hose has a predetermined length with a suitable cuff on each end thereof.  Each of the cuffs includes a snap lock.  The end fitting is a one piece molded member having a locking seat and a tapered end section or a threaded end section.  The tapered section is adapted to be forced into the cuff so as to spread the snap lock on the cuff.  The snap lock rides over the end section and drops into the locking seat formed therebehind. This is effective to lock the end fitting on the hose while allowing it to remain free to rotate inside the cuff.

Abstract: ABSTRACT OF THE DISCLOSURE      A lithium-bromine cell comprising a casing which can be of electrically conducting material and containing a lithium anode element from which a sealed conductor ex-tends through the casing.  A filling element which can be of electrically conducting material and which has a passage therethrough is fixed to the sealed casing with one end of the passage in communication with the interior of the casing and the other and externally exposed. Bromine is introduced through the passage to the interior of the casing into operative relationship with the lithium anode whereupon the passage is closed to complete the cell. The electrically conducting casing serves as a cathode current collector in operative contact with the bromine cathode, and after closing of the passage the electri-cally conducting filling element serves as an electrical terminal for the cell.  An electrical potential difference exists between the terminal and the anode conductor during operation of the cell.

Abstract: PHA.20.742 ABSTRACT:             A record structure for recording with a radi-ation beam uses a transparent disc or drum, a coaxial backing disc or drum and two coaxial resilient ring-shaped seals to provide an enclosure between the discs or drums.        Radiation-sensitive recording material on the side of the disc or drum within the enclosure is thereby protected from ambient  dust particles and other contaminations, while the gaseous or solid by-products of the inter-action between the recording material and the radiation beam in the area around which the beam impinges are substantially contained between the disc surfaces and cannot produce deposits on an objective lens used to focus the radiation beam or poison the user.
