The two canalizations (31-32) are obtained with several inner longitudinal seams (221) parallel to each other, as well as to the lateral seams (211) at an appropriate distance from these and each other and extending to the vicinity of the lower (212) and upper (213) peripheral seams at a suitable distance from these these longitudinal seams (221) are, furthermore, alternately interconnected at their ends by further pieces of lower (222), upper (223) orthogonals to the same so as to form a serpentine path; the two outer seams of such a group of inner longitudinal seams (221) go, furthermore, on to meet at the upper peripheral seam (213), in the centre of which it is circumferentially joined to one end of said supply tube (4) consisting of a flexible, flat tube.  In the upper part of said second canalization (32), there are tiny holes (5) having a suitable distance between them to allow the escape of compressed air put there by the supply tube (4), producing the water massage effect; suction cups (6) are attached to the underside thereof with a suitable distance between to allow the covering to be firmly fixed to the bottom of the tub, a conventional bathtub or the like used for water massage.     A similar coupling (7) is, moreover, suitably positioned on said first canalization (31) to allow the fluid with which it is filled to be emptied.

Patent CA-2021091-A1 (CA)
Inventor: CASHEN WILLIAM S
IPC: G21C19/14
Filed: 1990-07-12
Abstract: A bridge arrangement for supporting a fuelling machine for a nuclear reactor has one main tower which supports the bridge as a cantilever. A counterweight tower, adjacent the main tower, carries a counterweight which is substantially equal in weight to the weight of the bridge plus fuelling machine. The bridge is mounted to the main tower, and the counterweight is mounted to the counterweight tower, using rollers to provide for vertical movement with a minimum of friction. A vertical ball screw in both towers engages respective nuts on the bridge and the counterweight. Gears couple the two ball screws together so that when the bridge is raised the counterweight is lowered, and vice versa. While the bending forces change with the position of the fuelling machine along the bridge, the actual weight does not change. Thus the weight on the screw in the main tower does not change as it would do in one tower of a pair of supporting towers. Because of the counterweight, much less power is required to raise the bridge.

Title: Computerized tomographic image reconstruction method for helical scanning
Inventor: KING KEVIN F
IPC: G06T1/00
Filed: 1990-07-19
Abstract: Abstract of the Disclosure A method of reducing image artifacts in images acquired with fan beam, helical scanning, tomographic imaging systems uses half scans of less than 360° of projection data of an imaged object on each side of the slice plane being imaged.  The half scans are weighted with half scan weighting factors to compensate for redundant data and are weighted with helical scanning weighting factors to interpolate the half scans projection data to projection data at the slice plane.  The imaged object may be moved one slice thickness for each 360° of scanning so that the half scans are concentrated closer to the slice plane thereby reducing interpolation errors. Alternatively, for a series of slice images, the imaged object may be moved one slice thickness for each half scan to reduce average slice acquisition time.

Title: Rotor/stator combination
Inventor: SZABO LESLIE I
IPC: H02K23/02
Filed: 1991-02-12
Abstract: ABSTRACT OF THE DISCLOSURE         Improvements to electro-magnetic-mechnical machines are disclosed.  The improvements relate to improved geometrical structure for rotor/stator combinations; improved efficiency of operation; and d.c. motor/generators that do not require commutation.  The improved geometrical structure eliminates the reversal of magnetic flux directions around the face of a rotor.  This allows d.c. current to be supplied to, or derived from, the machine without the necessity of commutation.  Also, improved efficiency is obtained by supplying the machine with reactive current and also using a filter to remove d.c. components from developed counter-potentials.

Title: Method of calibrating enzyme immuno assay systems
Inventor: SAITO YUKIO
IPC: G01N35/00
Filed: 1991-03-13
Abstract: The present invention relates to a method of calibrating an enzyme immuno assay system.  A calibration curve is prepared by the use of standard samples having known concentrations, each one of the standard samples being measured by two optical detectors.  Conversion values of the outputs from the two optical detectors are determined from the resulting measured values, and the calibration curve is corrected on the basis of the conversion values of the outputs to establish a single new continuous calibration curve.  In this way, target materials in blood or the like can be measured with accuracy over large ranges of concentrations.

Abstract: An infusion catheter is provided having a main body including a continuous generally round cross-section about a longitudinal axis.  The body has proximal and distal ends.  A tip section has a round cross-section and is smaller in cross-section then the main body and ends in a tip.  The tip section is attached to the distal end of the main body at a transition portion which tapers smoothly from the main body to the tip section.  The main body and tip section define a primary lumen extending from the proximal end of the body to the tip and, the lumen is continuous and without misalignment where the main body meets the tip section.  This lumen has a longitudinal axis offset from that of the main body and the main body further includes a pair of side-by-side secondary lumens terminating at respective side openings in the main body.  A first of these openings is adjacent the transition portion and the second is spaced from the transition portion.  Plug material is provided in the main body between said second opening and the transition portion.  The catheter can have more than two secondary lumens.          The catheter is made using a process to align the body and tip section while heat and pressure cause the formation of the transition portion.

IPC: G06F11/08
Filed: 1991-06-21
Abstract: A bus interface between a data bus and data storage devices provides error protection for multi-byte data packets received from the bus and intended for storage on an associated storage device by checking the data symbols in a packet for errors using check sum and parity symbols included in the packet.  The bus interface then (i) encodes a predetermined number of data symbols to generate error detection symbols, (ii) again checks the data symbols for errors using the parity bits, and (iii) stores the data and associated error detection symbols in one of a series of linked buffers.  Each buffer holds enough the data and associated error detection symbols to fill one storage unit, or sector, on an associated storage medium.  A storage interface later retrieves the buffered data and error detection symbols, combines them with the address of a designated storage sector, and encodes the symbols to generate error correction symbols.  It then stores the encoded data, and error detection and correction symbols in the designated sector.  When the storage interface later retrieves the symbols from the sector, it corrects errors in the data using the retrieved error correction symbols.  It next removes the sector address from the error detection symbols and returns the data and error detection symbols to the bus interface.  The bus interface (i) generates parity bits, (ii) checks for errors using the error detection symbols, (iii) generates check sum symbols and (iv) transmits the data, check sum and parity symbols over the bus.  If the bus interface at any time detects an error, it stops the data transfer operation.
