Patent CA-1337463-C (CA)
Inventor: COMEAU FELIX J E
IPC: A61B5/097

Granted: 1995-10-31
Abstract: An apparatus  for delivering a gas  sample such  as  a  breath  sample  to  a  solid  state  sensor operating to sense the concentration of a constituent of the sample such as alcohol while the sensor is maintained within a predetermined temperature range is disclosed.   The sensor is disposed within a sensor chamber which communicates by way of a small bleed passageway with a second chamber formed in a conduit having an inlet upstream of the second chamber and an exhaust downstream thereof.  The pressure within the second chamber is passively regulated to lie within a predetermined range over an expected range of inlet pressures.  This regulation is accomplished by means of  flow  restrictors  disposed  between  the  second chamber and its inlet and exhaust and results in a bleed flow to the sensor through the bleed passageway which  is  sufficient  to  ensure  an  accurate  reading within a predetermined sampling interval while further ensuring that the bleed flow does not cool the sensor below its operating temperature range.  The lower end of the pressure range at which the second chamber is regulated is selected to correspond to a minimum flow sufficient to provide a deep lung breath sample when that minimum flow is continued with out interruption for  a  period  at  least  equal  to  a  predetermined sampling interval.   This minimum flow can be sensed for example by a pressure sensor operatively disposed in communication with the second chamber.  To ensure that the pressure sensor cannot indicate the presence of the minimum flow when the exhaust is blocked, the invention further contemplates connecting the pressure sensor differentially across one of the flow restric-tors separating the second chamber from its inlet and exhaust.

Abstract: ABSTRACT The disclosed method and apparatus provides for providing piecewise continuous addition of micro-spheroidal  ("MS")  Fluid Catalytic Cracking ("FCC") catalyst additives and/or bulk catalyst to an in situ circulating,  active catalyst inventory of a fluid catalytic cracking unit at programmed rates precisely controlled to sustain effective additive concentration while damping excessive performance fluctuations.  In a preferred version of this invention,  each of a series of such apparatus comprising one such device for each catalyst additive, is operated on a basic cycle time length during a portion of which the unit is engaged in active addition while in the remainder of the time it is passive, and wherein the timing being under the primary control of a process variable feedback signal.   An overriding secondary control, imposed by a fundamental performance criterion, may also be employed.

Title: Woven fabric from splittable ribbons
Inventor: KUMAR VIJAYENDRA
IPC: D03D15/02
Filed: 1989-04-26
Granted: 1993-06-29
Abstract: ABSTRACT A fabric, useful as a primary carpet backing, woven in both the warp and weft directions from filmy elements in the form of longitudinally-oriented, splittable ribbons formed from a blend of a major amount of polyester and a minor amount of a polyolefin.  The ribbons split longitudinally when punctured by a tufting needle, thus providing for a more secure grip on the tufted carpet yarn than that given by conventional polyester backings.  The use of polyester as a principal component overcomes certain drawbacks of polypropylene backings.  Alternative processes for making these fabrics, each involving a heat-treating step at a temperature of at least 150°F (66°C) for a sufficient period of time to render the ribbons splittable, are also disclosed.

Abstract: A magnetic  tape  recording  and playback apparatus includes  a  tape  driving  system  for  driving  a  tape,  a recording/playing system for recording/playing/erasing and a linking device for mechanically linking the operations of  the  tape  driving  system with  the  recording/playing system.  The tape driving system includes a motor, a gear train coupled to the motor and a reel shaft for rotating reels  of  the  cassette.   The  gear  train  includes  a planetary   gear   which   swings.    The   planetary   gear selectively rotates the reel shaft in correspondence with respective operation modes of the magnetic recording and playback  apparatus.   The  linking  means  includes  a  cam coupled to the planetary gear and a head base mounting a recording/playing  head. The  cam  transmits  the  driving power  from  the  motor  to  the  head  base through  the planetary gear.  The head base moves corresponding to the shape of the cam and in association with the operation of the  planetary  gear.   Operation  such  as  recording  and playing is carried out on the tape by the movement of the head base.

Abstract: A B S T R A C T     METHOD FOR CONTROLLING TWO INTERRRELATED   TRANSPORT MEANS AND MACHINE THUS CONTROLLED, ESPECIALLY A PERSONAL BANKING MACHINE     A method and personal banking machine is described by which two items such as cash and statement can be issued simultaneously through one and the same gate. The optimum point in time is determined and adaptively controlled so that the front edge of a statement touches a bundle of cash during issuing movement of the cash. Then both the cash and statement are moved together in their respective end positions. The method and the machine starts the statement transport after a certain monitored delay time DELTA STATEMENT. By calculating the time difference between the point in time at which the cash reaches its end position and the statement reaches its end position a new time delay DELTA STATEMENT is calculated for the next combined cash and statement issue operation.          The method provides for a secure reaching the desired predetermined end positions for cash and statement in the slot of an exit gate.

Abstract: Apparatus for installing cables with a certain stiffness, more in particular glass fibre cables, into a duct (6, 24) of a channelization system, using the working of a compressed gas, which apparatus is adapted to exert pushing forces on a cable (26) being introduced in order to support the compressed gas working on the cable in the duct. The apparatus comprises cable advancing means and gas inserting means. The cable advancing means include a hollow, substantially rectilinear cable lead-through channel (3) with an entrance end (4) and an exit end (5), at least one pair of wheels (8, 10; 9, 11) mounted opposite to each other for moving on a cable (26) disposed between these wheels into the direction of the outlet end (21) of the duct (6), and a pneumatic motor (15) coupled to at least one of said wheels for providing a driving couple to it. At least one of the wheels is coupled to a pneumatic piston/cylinder combination (13, 14), in such a way that when compressed gas is supplied to the pneumatic cylinder (14), transverse forces will be exerted on the cable (26) disposed between the wheels (8, 10; 9, 11). The gas inserting means include a gas channel (7), which debouches into the cable lead-through channel (3) and which is adapted for inserting compressed gas into the lead-through channel (3) between the wheels and the exit end (5) of the lead-through channel (3). The motor (15) is capable of providing a driving couple, which is larger than the driving couple, which has to act on the cable (26) to compensate a pressure difference existing at the inlet end of the duct between the pressure inside and the pressure outside the cable lead-through channel (3) as a consequence of inserting the compressed gas via the gas channel (7) into the cable lead-through channel (3). The pushing forces are exerted by the wheels on the cable (26) as a consequence of the cooperative effect of the driving couple and the transverse forces. The gas channel (7), the pneumatic motor (15) and the piston/cylinder combination may be coupled to the same compressor. For use in a tandem arrangement the apparatus comprises further a coupling unit (18) to be coupled to an outlet end (21) of a preceding duct section (24), and which includes a mainly hollow housing (19), an outlet pipe (23) for diverting a flow of gas, which may leave the outlet end (21) of the duct section (24), and an outlet opening (22) through which a cable may be led into the direction of the entrance end (4) of the cable lead-through channel (3). Advantages: the exerted transverse forces are very acurately adjustable and substantially constant; the apparatus is non-destructive to the cable when cable introduction is slowing down or stagnates; in a tandem arrangement the apparatus needs hardly any human interference and is safe for the operating staff. <IMAGE>
