Abstract: ABSTRACT OF THE DISCLOSURE     The disclosed holder is used to secure a collapsible umbrella to the top edge portion of an upstanding golf bag.          The umbrella, when erected, is adapted to shelter the bag and the clubs projecting from the bag top end, against adverse weather conditions.  The holder comprises two relatively-rotatable parts to angularly vary the position of the umbrella relative to the bag between a bag-shelter-ing position, a club-access position and an umbrella-storing portion; the collapsed umbrella then extending along the bag outside.

Abstract: ABSTRACT OF THE DISCLOSURE A dual threshold is used in a coherent phase shift keyed demodulator to distinguish situations in which an incoming carrier signal is expected from those open ended conditions when a receiver is active, but when an incoming signal is not imminently expected.  The use of a lower threshold permits more rapid detection and demodula-tion of a valid carrier signal by utilizing a standard which is less strict to determine the presence of a valid carrier signal when an incoming carrier signal is expect-ed.

Abstract: ALTERNATING COMMUNICATION CHANNEL SWITCHOVER SYSTEM       ABSTRACT OF THE DISCLOSURE        A redundant common communication:     system for a distributed process control or data processing system  has  multiple  stations             which  are coupled  to  at  least  two  redundant  communication channels  such as communication busses Each station            includes a transmitter for transmitting  data packets  and  a  receiver for receiving data packets.   Each data packet includes a channel selection field which identifies a selected channel to be used by all station during a succeeding  transmission  of  a  data  packet.   Each station            makes an assessment of quality of each channel based upon the occurrence of errors when that  channel  is  in  use.   The  station computes a margin value based upon assessed quality factors.   When   the   station              gets   an opportunity to transmit, the channel selection field of the transmitted packet identifies a channel which is selected based  upon  the  margin  value  and  the frequency of previous use of each of the channels.    As a result,  frequent  switching among the channels occurs,  with the percentage of use of each channel being  dependent  upon  the  assessed  quality of  that channel by the various stations

Abstract: ABSTRACT OF THE DISCLOSURE       Pipe handling systems are generally somewhat bulky, relying on a plurality of hydraulic cylinders and complicated linkages.  A relatively simple, compact pipe handling apparatus for use on a derrick of the type which can be rotated between the horizontal and the vertical includes an elongated track for mounting on one side of the derrick, a carriage slidably mounted on the track, three swing arms connected end to end, the first arm being connected to a rotary actuator mounted on the carriage, rotation around an axis perpendicular to the longitudinal axis of the derrick, a second rotary actuator between the first and second swing arms for rotating the second and third swing arms around an axis parallel to and spaced apart from the longitudinal axis of the derrick, a third rotary actuator for rotating the third swing arm, which carries a pair of jaw assemblies.  Thus, the apparatus can be used to grip a pipe section, move the pipe section up an inclined or vertical derrick, rotate the pipe section into a first position parallel to the longitudinal axis of the derrick and then into alignment with an existing pipe string in the centre of the derrick, and lower the pipe section into engagement with the existing pipe string for attachment thereto using a conventional top drive.

Abstract: ABSTRACT OF THE DISCLOSURE   A new and improved structure for transporting single component magnetic developer for developing latent electrostatic images or for removing residual developer from a charge retentive surface. In one embodiment of the invention narrow metal strips are embedded in the outer shell or cylinder of a conventional magnetic roll structure. The strips are very pointed adjacent the outer periphery of the shell. The sharp tips ensure a high magnetic field gradient when the magnetic roll disposed internally of the shell is rotated. The thinness of the strips causes them to respond to only the radial component of the magnetic field. Each strip responds to the oscillating radial field component slightly out of phase with its adjacent strip thereby creating a wave gradient along the surface which pulls and tumbles developer over the surface.

This drive unit comprises a motor and a drive pulley connected to the motor by a rotor which is rotated by the motor.  The motor has an actuator which is moveable from an idle position wherein the motor idles to an increased power position wherein the power output of the motor is increased.  First anchor means is used to anchor the drive unit in the ground in a stationary position.  There is also second anchor which are engageable in the ground at a distance from the drive unit and which has a support pulley connected thereto.  An endless cable extends between and is entrained about the drive pulley and the support pulley and has an upper portion and a lower portion.          Switch comprising a linkage is rotably connected to the actuator at one end and to the cable at the other end by regulator poller.  This switching means is operable to move the actuator to the idle position when the tension of each of the portions of the cable on the regulator roller are equal and to move the actuator to the increased power position when the tension of the portions of the cable are unequal.
