Inventor: BERGLOEF KLAS
IPC: F25B43/02
Filed: 1993-01-29
Abstract: An arrangement for removing from a refrigerating system or heat pump system a lubricating oil used together with a first type of refrigerant in the system and replacing this oil with an oil which is compatible with a second type of refrigerant, in conjunction with converting the refrigerating system or heat pump system from a system which operates with the first type of refrigerant to a system which operates with the second type of refrigerant. The arrangement includes an external apparatus (2) which is intended for connection to the system (1) to be cleansed. The external apparatus includes means (7, 10) for flushing the system with circulating refrigerant of the first type, this refrigerant being capable of dissolving the oil and, because it has a higher density than oil, also able to lift and entrain the oil. These means are intended to circulate the refrigerant through the whole or a selected part of the system (1) and the external apparatus (2). The arrangement also includes means (8) for vapourizing the refrigerant and oil mixture leaving the system so as to separate the oil from the refrigerant prior to returning the refrigerant to the system (1).

Title: Mounting of the bats of a reel on a crop harvesting header
Inventor: FOX THOMAS R
IPC: A01D57/02
Filed: 1995-12-20
Abstract: A reel of a header comprises a tube which is mounted on arms at ends of the tube for rotation about a longitudinal axis of the tube. At axially spaced positions along the length of the tube is provided a plurality of support members each lying in a radial plane of the tube and farming a disc surrounding the tube. The disc carries a plurality of brackets extending radially outwardly from the edge of the disc and each bracket carries a respective one of a plurality of bats extending longitudinally of the tube and at angularly spaced positions around the tube.  As the tube rotates the bats pass over a sickle knife of the header and sweep the crop onto a table of the header. The brackets are adjustable radially relative to the discs so that the brackets at the center of the tube are moved radially inwardly and the brackets at the ends of the tube are moved radially outwardly. This adjustment bends the bat relative to the tube in a slight curvature which is equal to the amount of deflection of the tube which occurs under its own weight due to sagging and due to acceleration of the tube over bumps. Thus the bat underneath the tube is substantially straight and can cooperate with a straight sickle knife. The bat which is above the tube is bent by a deflection which is substantially equal to double the deflection of the tube.

Title: Method and apparatus for removing artifact encountered during automatic blood pressure measurements
Inventor: JAYNE CYNTHIA PAULA
IPC: A61B5/0225
Filed: 1996-03-13
Abstract: A blood pressure monitoring system having a blood pressure cuff, an air pump applying pressurized air to the cuff; a valve to selectively vent the cuff, and a pressure transducer generating a signal indicative of the pressure in the cuff corresponding to an occlusive pressure exerted by the cuff on an artery and a transient fluid pressure in the cuff indicative of the amplitude of an oscillometric pulse. An analog-to-digital converter connected to the transducer samples the output of the transducer and generates respective digital samples corresponding to the output of the transducer. A processor receives the respective digital samples corresponding to the signal indicative of the steady state fluid pressure in the cuff and the signal corresponding to the amplitude of the oscillometric pulses. The processor also records in a table the steady state fluid pressure at which each measurement is made and the amplitude of the peak oscillometric pulses at such pressure. The processor also determines all local maxima of the amplitude of the oscillometric peaks in the table, and examines the longest sequences of the amplitudes of the oscillometric peaks at cuff pressures adjacent to the cuff pressure at which each of the local maxima was obtained. Then, the processor chooses one of the local maxima as a true maximum value based on a comparison of the longest sequences adjacent to each of the local maxima and computes blood pressure using this value.
Patent CA-2172344-A1 (CA)
Inventor: KOTZUR FRANK W
IPC: D01H1/36
Filed: 1996-03-21
Abstract: A winding apparatus is disclosed for winding of filamentary material. The apparatus includes a first and second spindles. They are independently operable and rotate about parallel spaced horizontal axes. First and second mandrels are removably mounted on the respective spindles. A traverse guide is mounted to the frame of the apparatus for reciprocating movement along an axis parallel to,  and  spaced  from,  the  horizontal  axes.  The reciprocating of the traverse guide is effected in cooperation with independent rotary drives of the spindles to consecutively wind the filamentary material on the first and second mandrels. The apparatus is further equipped with transfer device movably secured to the frame and adapted to guide the filamentary material which extends from the traverse guide from a completely wound first or second mandrel to the other unwound mandrel for winding thereon. A control device governs the operation of the drives   for   independently   rotating   the   spindles,   the reciprocating means and the transfer means for successively winding the material onto one or the other mandrel in a desired universal wind. The advance in the art is in that a high speed winding apparatus is provided for automatically transferring the filament from one rotating winding diameter to another non-rotating winding diameter to enable the filament to be wound in an  essentially  non-stop  operation.  The traverse  mechanism operates  at  higher  speeds  than  that  of  the  barrel  cam configurations of known traverse mechanisms thereby improving the productivity of the operation.

The lower portion of the housing is in a retracted position when the sheet is wound up around the spool and in an extended position when the sheet is unwound from the spool.   The sheet contains calendar indicia which is displayed when the lower portion of the housing is in an extended position.  A winding mechanism,  associated with the spool,  winds the sheet around the spool and moves the lower portion of the housing from an extended position to the retracted position.          The lower portion of the housing substantially mates with the upper portion of the housing when the lower portion is in the retracted position.  The sheet of flexible material has an erasable surface capable of being erasably written upon.
