Abstract: METHOD AND APPARATUS FOR MANUFACTURING                     WRAPPED YARNS                         ABSTRACT       Method and apparatus for producing high quality wrapped yarn by a wrapping operation wherein a binder strand, carried by a supply package supported by a rotatably driven hollow spindle, is fed to the free end of the hollow supply spindle and wrapped around a core strand moving through the hollow spindle.  The binder strand inherently balloons outwardly in its path of travel from its rotating supply package to the core strand being wrapped.  The zone in which the binder strand bal-loons is enclosed to isolate it from the ambient air about the wrapping apparatus to thereby substantially preclude pick up of fiber waste on the binder strand and thus prevent the form ation on the binder strand of imperfections or "flags" which result in loss of yarn product quality because of yarn break-age or entrapment in the wrapped yarn.  Suction means communi-cates with the hollow spindle to attract the core yarn and facilitate passage of the wrapped yarn therethrough.  Isolation of the zone in which the binder strand balloons is obtained by enveloping the package and balloon forming region of the bind-er strand with an enclosure.  The top of the enclosure is pro-vided with an aperture to permit the delivery of core strand through the enclosure to the hollow spindle.  Preferably, the inside margins around the enclosure aperture are designed to define with the adjacent end face of the hollow spindle an annular radially extending passageway for passage of the binder yarn, and means are provided to adjust the spacing between the hollow spindle end face and the aperture margins to optimize the exclusion of fiber waste from the ballooning zone.

Abstract: UNIVERSAL SIGNAL GENERATOR FOR GENERATING   TELEPHONE SYSTEM HIGH LEVEL SIGNALS Abstract of the Disclosure In a telephone switching facility, line circuits are arranged in groups, each including a local ringing battery bus, and a universal high level signal generator (UHLSG) for providing ringing and other high level signals to the line circuits via the local ringing bus.  Each generator is responsive to address signals from a controller in the switching facility to generate selected high level signals.  The UHLSG includes a switching bridge driven by a width modulated signal stream of periodically occurring pulses having assertion times suitable for developing a high level signal across a network at the output of the switching bridge.  The width modulated pulses are generated from period and time signals.  The period signal occurs once with each sequence in repetitively generated data byte sequences.  The time signal occurs with correspondence between a selected stored data byte and an instant one of the data bytes of the sequence.  A plurality of the stored data bytes are arranged in ranges in a storage circuit.  One bit in the last data byte in each range causes the storage circuit's next readout to be from the beginning of a range as directed by the controller in the switching facility.     - i -

Abstract: SEQUENTIAL ENCODING AND DECODING OF    VARIABLE WORD LENGTH, FIXED RATE DATA CODES          Abstract of the Disclosure A method of encoding or decoding data in a code of variable length words and fixed rate comprises the steps of (1) initially entering a constant number (k) of input bits into a shift register; (2) entering a constant number (m) of input bits into the shift register; (3) encoding or decoding a con-stant number (n) of bits in response to the contents of the shift register; and (4) repeating steps (2) and (3) until the input bits are exhausted.  To complete the encoding or decoding, steps (2) and (3) are further repeated with dummy input bits until (k) dummy bits have been entered into the shift register.          The encoding or decoding of (n) bits may be affected by auxiliary state variables which account for the position in the shift register of the boundary between words.

Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed apparatus for measuring the dew point which is arranged to carry out a method in which there is repeatedly performed a measuring cycle in which a body on which dew can form is cooled gradually until the form-ation of dew thereon is detected by detecting means, the temperature at which dew forms on said body being recorded in the apparatus and the temperature of said body being subsequently allowed to rise prior to cooling again in the next succeeding cycle.  The temperature of said body is monitored continuously and the rate of cooling of the body in each cycle is controlled in dependence upon the differ-ence between the instantaneous temperature of said body and the dew point temperature measured in a preceding cycle and recorded in the apparatus in such a way that the rate of cooling is lower for at least a range of temperatures closer to said dew point temperature recorded in said previous cycle than for instantaneous temperatures of said body further from said dew point temperature recorded in said previous cycle.  Thus, it is possible to combine the advantages of a rapid cooling rate, affording a high sampling frequency, and of a slow cooling rato, affording good accuracy.

Abstract: SEMICONDUCTOR PRESSURE DETECTOR APPARATUS WITH ZERO-POINT TEMPERATURE COMPENSATION                 Abstract of the Disclosure A semiconductor pressure detector apparatus has a strain - electric signal conversion bridge composed of four semiconductor strain gauges.  An amplifier serves to maintain the sum of currents flowing through the bridge at a predetermined value.  The midpoints of a pair of arms constituting the bridge are respectively connected to the positive inputs of two negative feedback amplifiers, the outputs of which are applied to a differential amplifier.          An output proportional to the difference of the outputs of the former amplifiers appears at the output terminal of the latter amplifier.  A potential equal to potentials that appear at the midpoints of the bridge arms when the bridge is balanced at a predetermined temperature and under a predetermined pressure is generated by two resistances connected in series with a supply voltage.  This potential is applied through a switch to either of the negative in-puts of the two negative feedback amplifiers to achieve zero-point temperature compensation of the apparatus in an improved manner.

The apparatus includes a single, multiple accumulator arm which has three joined members.  A first member is pivotally connected to the frame of the tree harvester and the second member is pivotally connected to the first member and movable relative to the first member between an open position and a closed position.  The second member is maintained in one of the open and closed positions during pivotal movement of the first member.  A third member is pivotally connected to the second member and biased so that it can be folded and removed from between a tree and the frame and unfolded to later accumulate trees against the frame.  This simple structure uses only one movable accumulator arm instead of two.
