Title: Multiline check valve assembly
Inventor: RICHMOND FRANK M
IPC: A61M5/14
Filed: 1990-07-11
Abstract: ABSTRACT OF THE DISCLOSURE      A multiline check valve assembly has an elongated body which defines a fluid passageway and which is formed with a plurality of valve cavities that are in fluid communication with the fluid passageway.  Each valve cavity has a resilient valve element disposed within the cavity and each valve element rests in the cavity with one end against a protrusion disposed in the cavity for centering the element within the cavity.  The resilient valve element is biased to urge its other end against a valve seat that surrounds an opening to the valve cavity to create a fluid tight seal with the valve seat and close the opening.     In   addition,   an   access   port   is   formed circumferentially around both the valve seat and opening to establish a fluid communication path through the access port to the fluid passageway in the body when the valve element  is seperated  from  the  valve  seat.     Specifically,  when  an appropriate fluid line connector is inserted into the access port to urge against the resilient valve element,  the valve element is deformed away from the valve seat to complete the fluid communication path between the access port and the fluid passageway.

Patent CA-2045385-A1 (CA)
Inventor: WIENER MICHAEL J
IPC: G06F7/52
Filed: 1991-06-25
Abstract: For a public key encryption system, for example using the RSA (Rivest, Shamir, and Adleman) algorithm, large numbers, for example each of the order of 256 bits and represented by a plurality of sequentially stored words, must be multiplied together during a modular exponentiation process for coding information. To achieve this at high speed, there is described a method using a digital signal processor which has two accumulators for accumulating products of words, each accumulator having a capacity of more than twice the size of the words which are multiplied. The two accumulators are used alternately for accumulating partial products of the same significance in a multiplication of two numbers. Pointers to the sequentially stored words are incremented in opposite directions to point to words to be multiplied to form partial products of the same significance, and the pointer incrementing directions are changed for sets of partial products of increasing significance. The pointer control and alternating use of the accumulators enables a significant increase in multiplication, and hence coding, speed to be achieved.

A means for varying the water in the space between the inner and outer exhaust gas housings between a first lower level and a second upper level responds to an operating condition in the powerhead, and an idle exhaust gas discharge means operates only when the water in the annular space between the inner exhaust housing and the outer gas housing is at the first lower level.
Patent CA-2046663-A1 (CA)
Inventor: PODOLOFF ROBERT M
IPC: G01L5/00
Filed: 1990-12-11
Abstract: A force and pressure sensor is provided having two sets of parallel electrodes (4) which are positioned facing one another and arranged so that electrodes of one set cross the electrodes of the second set at an angle to create a plurality of electrode intersections. Pressure-sensitive resistive material (5) lies between the electrodes at each intersection. An adhesive layer is applied to at least one of the electrode sets in areas between electrode intersections to secure the first and second electrode sets in facing relationship, the adhesive layer preferably being applied in a pattern which provides passages where the adhesive layer does not exist to allow air to escape from interior areas of the electrode set. The thickness of the adhesive layer may be adjusted to permit pre-loading or to provide a threshold level for the sensor. In order to permit electrodes of the electrode set to be trimmed around their periphery, electrical contact to each electrode of the electrode sets is made intermediate the ends of the electrodes. This is accomplished by providing an insulating layer (3) over the rear of each electrode set having holes therein at the desired intersection points and having a plurality of connecting conductors on the back of the insulating sheet, one for each electrode, which make contact with the corresponding electrode through the hole in the insulting sheet.

IPC: B65D55/06
Filed: 1991-07-19
Abstract: ABSTRACT OF THE DISCLOSURE           This   relates   to   an   improvement   of   a conventional closure having a tamper evident feature in the form of a safety button.  In accordance with the improvement,  the  surface of  the  safety  button  is provided  with  a  coating  in  the  form  of  a  suitable binder    incorporating    rupturable    microcapsules containing  an  FDA  approved  colorant.  A  relatively stiff  layer  of  translucent material  overlies an end panel of the closure in position to be engaged by the microcapsules   and   to   effect   rupture   of   the microcapsules  when  the  safety  button  everts  from  a lower axial position to an upper axial position and the microcapsules strike against the underside of the layer of   translucent   material.   In   order   to   prevent accidental rupture of the microcapsules prior to the closure  being  applied  to  a  container,  there  is incorporated  in  the coating  spacers  which  normally prevent  the  rupture  of  the  microcapsules  during conditions   of  manufacture   and   handling.   The colorant carried by the microcapsules will give a clear and  irreversable  indication  of the  opening  of  the container.
