Filed: 1993-06-21
Abstract: A DOUBLE-ACTING PISTON PUMP                      ABSTRACT    In a piston pump or engine, the manner of translating rotary action of the drive to the reciprocating action of the piston in a cylinder can have a numerable variations.  In the present invention a pair of identical cams and cam-followers actuate a double - acting or two - headed piston in a configuration wherein the two cam followers are integrated within the body of the piston and the cams are integrated within the cylinder block.  The arrangement has considerable intrinsic strength and eliminates the need for the wrists, arms, and elbows which usually form part of mechanisms designed to transfer rotary action into linear action and vice-versa.
Patent CA-2098934-A1 (CA)
Title: Circular Limiter
Inventor: BETTS WILLIAM L
IPC: H03M13/23
Filed: 1993-06-22
Abstract: The effect of non-linear distortion on a received signal point is reduced by the use of a circular limiter. In particular, the circular limiter computes the distance of the received signal point from the center of the signal point constellation. If this distance exceeds a desired limit, then both dimensions of the received signal point are reduced by the same factor to maintain the original phase. This reduction in the dimensions of the received signal point decreases the corresponding errorsignal that is calculated by a Viterbi decoder. As a result, this further reduces the value of the accumulated path metrics of the Viterbi decoder which results in animprovement in system performance. In addition, the circular limiter also realizes a slight improvement in system performance against additive white Gaussian noise. The value of the limiting distance can either be predefined, or determined adaptively to match channel conditions of the communications system.

Patent CA-2110373-A1 (CA)
Title: Methanol synthesis
Inventor: ABBOTT PETER E J
IPC: C07C29/152
Filed: 1993-11-30
Abstract: The purge gas from a methanol synthesis loop is subjected to a further step of methanol synthesis, preferably while in indirect heat exchange with the purge gas undergoing heating to the synthesis inlet temperature so that the reacted purge gas, containing synthesised methanol, leaves the synthesis catalyst at a temperature below the maximum temperature achieved by the reacting purge gas during passage over the catalyst.      The synthesis loop can be operated less efficiently, eg at a lower pressure or with added carbon dioxide, than is conventional since the additional methanol produced from the purge gas compensates for the loss of loop efficiency.      The addition of the purge gas synthesis stage enables existing plants to be uprated by lowering the loop pressure, thus enabling a greater throughput through the synthesis gas compressor to be achieved.

Abstract: A method for terminating an electrical conductor, comprises an outset step of defining a housing having an open end and a closed end and at least one passage therethrough for entry of the conductor into the housing to permit a termination end of the conductor to be resident interiorly in the housing. Next, the housing passage is closed and the housing is disposed with the housing open end vertically above the housing closed end. With the housing so disposed, sealant gel is introduced in liquid state interiorly of the housing. While the sealant gel is in the liquid state, there is secured with the housing, through the housing open end, apparatus for subsequent use in terminating the conductor, Upon transition of the sealant gel to a cured state, the housing passage is opened. To complete the conductor terminating method, at the installation site, the conductor is inserted into the housing passage and into registry with the terminating apparatus. One now operates the terminating apparatus to terminate the conductor. An insulation-displacement contact defines first and second beams bounding a conductor-receiving slot, the beams defining respective first and second notched insulation-displacement segments at respective leading and trailing parts thereof which are of triangular configuration having triangle bases aligned with the conductor entry passage.

Title: Self-Expanding and Reclosable Flexible Pouch
Inventor: COOK CHARLES D
IPC: B65D30/16
Filed: 1992-06-26
Abstract: A sealed, self-expanding, reclosable, flexible pouch (20) having a pair of extensible stays (50) located in the throat area of the pouch. The extensible stays (50) are biased toward a circular configuration but are initially held substantially flat in a stressed condition by the pouch's sealed top portion (31). When the pouch's top portion is removed, the the extensible stays (50) expand to their relaxed expanded configuration and thereby expand and open the throat area (52) of the pouch. An inwardly oriented male securement means (54) is attached to one extensible stay (50) and extends along the throat area (52) of the pouch. A complementary inwardly oriented female securement means (56) is attached to the other of the opposing extensible stays (50) and extends along the throat area of the pouch. The complementary male and female securement means (54, 56) permit the throat area (52) of the pouch (20) to be sufficiently closed after initial opening, thereby constraining the pouch's contents.

Title: Blood collection device
Inventor: REICHENBACH JUDITH A
IPC: G01N33/48
Filed: 1994-01-24
Abstract: ABSTRACT   The present invention relates to a blood collection device for chemical analysis of plasma specimen. Said device is a test tube made of polyethylene terephthalate, etc., onto an interior wall of which anticoagulant, such as lithium heparin or sodium heparin, is applied by a spray coating process. Anticoagulant is applied onto an interior wall in the form of fine mist by a spray coating process using a carrier solvent, preferably water. The main advantages of the plastic tube with spray coated anticoagulant on the tube interior wall are more precise, stable, uniform and dry anticoagulant fill and improved dry anticoagulant dissolution into blood specimen. Because of the fine mist of anticoagulant, the actual surface area of anticoagulant exposed to blood is maximized. The precision of the anticoagulant fill is improved by tailoring the solution concentration and dispensed volume. That is, a high precision metering system can be used to deliver the solution to the spray coating system. This is the only method for precise and efficient use of heparin in a uniformly distributed manner. This method improves the delivery of the anticoagulant solution to a plastic tube, rectifies unprecise distribution of anticoagulant onto the wall of the tube and facilitates dissolution of anticoagulant, upon blood collection.
