Title: Elastic shaft coupling
Inventor: HILLE FRIEDRICH
IPC: F16D3/62
Filed: 1986-10-31
Granted: 1991-06-25
Abstract: ABSTRACT            The two hubs (1) are elastically joined to a hollow shaft (2), which surrounds the hubs, by means of six elastically resilient links (3) which are bolted alternatingly in an hexagonal pattern to a hub flange (10) and a shaft flange (20) at the ends of the coupling.  This permits parallel and angular misalignments according to the cardanic principle while torque is being transmitted.  Because the flanges lie in the same transverse plane, the coupling is protected against slipping in the event that the resilient link elements should fail.  Because the links are externally mounted, they permit optimum cardanic motion.  The hubs may be fitted inside the hollow shaft (short configuration) or they may bolted on so as to project beyond the ends of the hollow shaft (long configuration).

Title: Powered pipe wrench
Inventor: KILLIAN RICHARD H
IPC: B25B21/00
Filed: 1986-11-03
Granted: 1991-01-15
Abstract: ABSTRACT     A pipe wrenching tool adapted to be powered by a hand held auxiliary power drive mechanism is formed with a support for a drive wheel and an idler wheel with the idler wheel being movable with respect to the drive wheel to adjust the tool for differing sizes of pipe. The tool is adapted to interface transversly to the axis of the pipe to be wrenched with the drive wheel engaging the pipe without requiring a part of the tool to circumscribe the pipe. The rotational axis of the idler wheel and rotational axis of the drive wheel are off-set with respect to each other to cause the pipe being wrenched to be forced into the tool. The tool is adapted to have the auxiliary drive source attached at either side of the tool and at the side of the tool away from the pipe so that the tool may be used to engage and wrench pipe in confined spaces. Only the wheels of the tool are rotated; the tool need not rotate wiht respect to the pipe.

Patent CA-1265271-C (CA)
Title: Bit interleaved multiplexer system providing byte synchronization for communicating apparatuses
Inventor: MANNING DAVID J
IPC: G06F5/10
Filed: 1987-06-15
Granted: 1990-01-30
Abstract: ABSTRACT A bit interleaved multiplexer system permitting byte synchronization of apparatuses communicating thereon without the consumption of additional aggregate bandwidth is provided. The system comprises a multiplexer, a demultiplexer, and an aggregate line. The multiplexer includes a transmit frame which includes a memory means and at least one recirculating counter which is programmed according to a framing algorithm, and a transmit data buffer and transmit mark buffer for each terminal which is to be connected to the system. Every time the transmit frame requests a predetermined bit of a byte (e.g. an MSB), a "1" is marked in the mark buffer. When a bit leaves the mark buffer it causes the terminal to write a bit into the transmit data buffer, with the written bit being an MSB when the bit leaving the mark buffer is a "1". By arranging the delay through the transmit mark and data buffers to be equal to I(L) + C, where I is an integer greater than zero, L is the length of a byte, and C is a contant phase shift, when the transmit frame requests an MSB, an MSB will be sent by the transmit data buffer C requests later. If C is set to zero, an MSB will be sent when the transmit frame so requests. The demultiplexer of the invention includes a receive frame which is synchronized with the transmit frame and which includes a memory means and at least one recirculating counter, and a receive data buffer and receive mark buffer for each terminal which is connected to the system. Every time the framing algorithm indicates that an M&B is being received by the receive frame, a "1" is marked into the receive mark buffer while the bit is forwarded to the receive data buffer. Because the receive mark and receive data buffers are equal in length, the terminal receiving information from the buffers will be provided with the information as to whether the received bit is an MSB.

Title: Method for more accurately determining thermal neutron decay time constants
Inventor: ATTALI GEORGE
IPC: G01V5/10
Filed: 1987-11-12
Granted: 1991-03-26
Abstract: Abstract of the Disclosure The   present   invention   comprises   a   method   for determining  the  transition  point  between a portion of  a curve comprising a statistically single exponential function and another portion of the curve comprising the composite of said exponential function with another function.  The method of  the  present  invention  is  useful  in  determining which portion  of  a  composite  decay  curve  is  statistically equivalent to a single exponential function.  The method of the present invention is particularly useful in the oil and gas  industry  in  connection  with  the  rapid and  accurate determination  of  the  decay  constant  of  the  formation surrounding  a  borehole.    In  the  method  of  the  present invention,  the measured decay function following radiation of the formation with a burst of fast neutrons is integrated in a plurality of contiguous time gates between the end of the  neutron  burst  and  the  decay  to  background radiation levels.   The decay function is integrated over each of two subsets of contiguous gates whose leading edges are offset by  a  known  lime  width.    A  succession  of  ratios  is constructed for a succession of test intervals each defined by two such subsets.   Ratios for different test intervals, each  successively  further  in  time  from  the  end  of  the radiation burst,  are statistically compared.   Statistical compatibility  of  two  successive  ratios  implies  that  the decay  function is a statistically single exponential over the  lime  spanned  by  the  two  test  intervals.   Once  She portion of the decay curve represented by a statistically single   exponential   function   representative   of   the surrounding  formation  is  determined,  the  formation  decay constant is easily and accurately determined.

Abstract: MULTI-MODE COMBUSTER     ABSTRACT OF THE DISCLOSURE     An  optimized  thermal/catalytic  combuster  for  the efficient oxidation of volatile organic compounds (VOC) in air.   As an example, the invention is directly applicable to   remedial   action   for   clean-up   of   ground   sites contaminated by spills or leaks of gasoline, organic paint solvents  and  the  like,  by  a  process  known  as  air extraction.   A thermal combuster and a catalytic oxidizer are  interconnected by piping and control valves so that when one  such element operates,  the other is quiescent, depending on the concentration of combustible vapors in the extracted air.  A dilution air valve, a heat exchanger, an electric heater, or a connection to a supplemental supply of clean-burning  fuel,  or  all  these  devices,  may  be provided to ensure efficient operation.   In an alternative embodiment,  an internal combustion engine may be used in place of the thermal combuster.  The engine can be used to supply  power  for  other  uses  within  the  system or  for external use.   In a  further alternative,  a basic vapor contamination  abatement  system  addressed  specifically to extraction  vapors  from  contaminated  soils  comprises  a vacuum  pump/compressor  transmitting  the  vapors  from  the soil  to a  catalytic  oxidizer,  without use of a thermal combuster.
