Title: Apparatus and method for delivery of involatile reagents
Inventor: KIRLIN PETER S
IPC: C23C16/18
Filed: 1992-12-11
Abstract: A process and apparatus (100) for delivering an involatile solid source reagent material having a vapor pressure of less than about 0.1 torr at 25 ·C and 1 atmosphere conditions, and which is thermally unstable at its vaporization temperature, as a source reagent material vapor into a CVD reactor (12) comprising a vaporization zone (22) and a flash vaporization matrix structure (26) for flash vaporizing the involatile solid source reagent material.

Title: Sewing apparatus for making composite drawcord/elastic waistband
Inventor: BRYANT DON E
IPC: D05B35/06
Filed: 1994-06-24
Abstract: SEWING APPARATUS FOR MAKING COMPOSITE DRAWCORD/ELASTIC WAISTBAND                  ABSTRACT OF THE DISCLOSURE A sewing apparatus combines an elastic band with a non-elastic draw cord to form a composite band. The apparatus includes a sowing machine for sewing the draw cord to one surface of the elastic band. The sewing machine forms a plurality of stitches that collectively define a longitudinally extending channel encasing the draw cord. The elastic band is fed through the sewing machine by a set of feed rollers disposed upstream from the sewing machine and a set of draw rollers disposed downstream of the sewing machine. The draw rollers are operated at a higher feed rate than the feed rollers to stretch a segment of theelastic band as it passes through the sewing machine. The draw cord is fed through the sewing machine in side-by-side relationship with the elastic band and is secured to the band while the band is in a stretched condition. The sewing apparatus of the present invention can be used in line with a knitting machine in which the elastic band is formed, or can be used standing alone in an independent operation.
Patent CA-2126834-A1 (CA)
Title: Preparation of Methylamines Using Shape Selective Chabazites
Inventor: WILHELM FREDERICK C
IPC: C07C211/04
Filed: 1994-06-27
Abstract: This invention relates to a process for producing a non-equilibrium distributionof methylamines by the catalyzed reaction of methanol and/or dimethyl ether withammonia and by the catalytic reforming of a methylamine containing feedstock. One process selectively affords a reaction product enriched in mono and dimethylamines and low in trimethylamine, at high conversion of methanol or dimethylether. A variation of the process effects reforming a methylamine containing feedstock, optionally containing ammonia over a catalyst. The key to achieving this low TMAselectivity at high conversion resides in the use of a microporous zeolite, preferably chabazite, catalyst having a geometric selectivity index (GSI) less about 3, a shape selectivity index (SSI) greater than about 5 and a sorption capacity for 1-PrOH of at least 0.5 mmol/g.

Filed: 1994-06-29
Abstract: ABSTRACT OF THE DISCLOSURE      An espresso machine has an underside provided with a brewing head into which a strainer holder having a handle can be inserted from below with a strainer inserted in the holder.  The brewing head has slots and the strainer holder includes corresponding lugs that fit through the slots so that the strainer holder can be released from or locked to the brewing head by a pivoting movement of the strainer holder around an axis of the brewing head which places the lugs in or out of alignment with the slots, respectively.  A positioning ring has a top end rotatably secured to the brewing head and a cutout that is open toward the bottom end of the positioning ring for receiving the handle of the strainer holder.  A mechanism cooperating between the positioning ring and the brewing head locates the positioning ring in an initial position so that when the cutout in the positioning ring receives the handle of the strainer holder, the strainer holder can be raised and inserted into the brewing head with the lugs on the strainer holder in alignment with the slots in the brewing head.

Title: Ski attachment for a wheeled vehicle
Inventor: DUNCAN D SCOTT
IPC: B62B19/02
Filed: 1994-10-05
Abstract: ABSTRACT OF THE DISCLOSURE: A ski attachment for operatively mounting onto one wheel of a wheeled vehicle, typically an unpowered wheeled vehicle such as a baby carriage or wagon, is disclosed. The wheel has an annular tire portion and a thinner centrally disposed hub portion. The ski attachment comprises a generally planar,elongated runner portion and upturned front and rear portions. A single attachment member has first and second co-operating arm members mounted on said base portion and extending upwardly from the ski member with first and second opposed gripping members mounted on the first and second arm members, respectively. The first and second gripping members are shaped and dimensioned so as to engage the hub portion of the wheel. A spring member is used to bias the first and second arm members into closing engagement so as to provide a gripping force therebetween. The gripping force is sufficient so asto cause the first and second opposed gripping members to grip the hub of the wheel and thereby keep the ski attachment operatively mounted on the wheel. The ski attachment is mounted on the wheel such that the single attachment member grips the wheel at the bottom thereof, at substantially the same locationthat the wheel rests on the ski attachment. The first and second arm members of the single attachment member are shaped and dimensioned so as to position the first and second opposed gripping members substantially in radial alignment on the wheel with the segment of the ski attachment that receives the annular tire portion of the wheel.

Inventor: DANLEY ROBERT L
IPC: G01N25/00
Filed: 1994-10-26
Abstract: The present invention is an infrared-heated differential thermal analyzing instrument.  The instrument uses an actively cooled heat sink, and a heat flow restricting element connecting the heat sink to a differential thermal analysis sensor.  An IR heater directs IR radiation onto the lateral surfaces of the heat sink and the heat flow restricting element.  These lateral surfaces are polished and coated with a high IR reflectance coating, so that heat absorption is minimized.  The IR heater preferably uses either elliptical or parabolic mirrors to focus the IR radiation onto the heat sink and the heat flow restricting element.         A second embodiment of the invention uses two heat sinks, and two heat flow restricting elements, mounted on either side of the differential analysis thermal sensor.

Filed: 1993-07-16
Abstract: In a PWM inverter using a three-arm modulation method, the apparatus and method are for controlling the current without missing the zero vector by switching the method to a two-arm modulation method near the voltage saturation. A PWM inverter using a three-arm modulation method comprises a timing data generating unit (32) which generates the timing data for the three-arm modulation based on the voltage vector times T.lambda., Tµ, and To from a PWM pattern operating unit (31), a timing changeover switch (33) which switches over this timing data to each phase time, and a timing data generating unit (41) which generates the timing data for the two-arm modulation from the voltage vector times. The zero vector time To is compared with the set value K,Tdly for the dead time comperisation by a comparison circuit (45) having the so-called hysteresis. Thus, if the zero vector time becomes short, the data generated by the timing data generating unit (41) are output to the timing change-over switch (33) by a modulation changeover switch (47) so that the PWM pattern is for the two-arm modulation method.
