Patent CA-2069639-A1 (CA)
Title: Active filter circuit
Inventor: HECK JOSEPH P
IPC: H03H11/04
Filed: 1991-08-19
Abstract: Abstract of the Disclosure A filter circuit disposed upon a single integrated circuit comprised of active filter elements including transconductance elements for a radiotelephone. The bandwidth of the passband of the filter is variable to pass alternately, signals of either a first bandwidth or a second bandwidth for passing, for example, signals generated in a conventional, cellular communication system, or a cellular communication system of increased capacity. Fine tuning of the bandwidth of the passband of the filter permits blocking of noise signals positioned, in frequency, proximate to a received, information signal.

Title: Method and apparatus for detecting fuel problems in an internal combustion engine
Inventor: HANSON JAY L
IPC: F02D17/04
Filed: 1992-07-10
Abstract: 56,752 ABSTRACT OF THE DISCLOSURE         Methods   and   apparatus   for  detecting  fuel problems of an internal combustion engine,  including low fuel, a  plugged fuel  filter, a pinched fuel line, air in the fuel system, and gelled fuel.  The detection of a fuel system  problem  is followed  by  engine  shutdown,  with shutdown  being  initiated   quickly   enough   to  retain sufficient fuel  in the fuel system to re-start the engine without the necessity of priming.   The invention includes the detection  and counting  of predetermined engine speed fluctuations.  A timer  is started  upon the  detection of the   first predetermined   speed  fluctuation.    If  a predetermined count is reached before the  timer reaches a predetermined time  value, the engine is shutdown when the count is  reached.   If the  timer reaches  the time value before the  count value  is reached, the counter and timer are reset  to  await  another  predetermined engine speed fluctuation.

Title: Effective sealing device for engine flowpath
Inventor: POPE ADAM NELSON
IPC: F02C7/28
Filed: 1992-08-13
Abstract: ABSTRACT OF THE DISCLOSURE    A ring seal having a continuous circumferential outside diameter seal dams on the high pressure side of the ring seal.   The seal dam is aerodynamically connected to a low pressure side of the ring seal by axial vents.  A plurality of upstream face vents on the  high  pressure  side  of  he  ring  seal  are aerodynamically connected to corresponding upstream transverse sealing dam.   A plurality of downstream face vents on the low pressure side of the ring seal are   aerodynamically  connected  to  corresponding downstream transverse sealing dam.  The upstream and downstream face vents serve to reduce an axial force exerted against the ring seal and the outside diameter vents which are aerodynamically coupled to the outside diameter seal dams serve to increase a radial force which pushes the ring seal against a stationary outer seat causing the ring seal to maintain a desired fixed position.

Patent CA-2079817-A1 (CA)
Inventor: GORDON STEVEN J
IPC: G01C15/00
Filed: 1991-03-22
Abstract: The invention is a three dimensional sensing system which utilizes two flexibly located cameras for receiving and recording visual information with respect to a sensed object illuminated by a series of light planes. Each pixel of each image is converted to a digital word and the words are grouped into stripes, each stripe comprising contiguous pixels.      One pixel of each stripe in one image is selected and an epi-polar line of that point is drawn in the other image. The three dimensional coordinate of each selected point is determined by determining the point on said epi-polar line which also lies on a stripe in the second image and which is closest to a known light plane.

Abstract: ABSTRACT OF THE DISCLOSURE    A swivel type end fitting for a tube or hose includes a hollow cylindrical insert having a first end portion, an intermediate portion, and a second end portion.  A first external shoulder is defined between the first end portion of the insert and the intermediate portion, while a second external shoulder is defined between the intermediate portion and the second end portion.  The end fitting also includes a swivel nut having an internal shoulder defined thereon.  During assembly, the swivel nut is moved axially over the insert until the inner shoulder thereof engages the first external shoulder of the insert.  The end fitting further includes a hollow cylindrical collar having a partially closed end portion.  During assembly, the collar is moved axially over the insert until the partially closed end portion thereof engages the second external shoulder of the insert.  The tube or hose is inserted into the end fitting about the insert and within the collar until the leading edge thereof engages the partially closed end portion of the collar.  Once the end fitting has been assembled in this manner, a conventional crimping machine can be used to compress portions of the collar about the end of the tube or the hose to retain the end fitting thereon.

IPC: H01L41/12
Filed: 1990-08-08
Abstract: The invention relates to an elastic clamping device for at least one body with magnetostrictive properties, wherein a pressure means presses said clamping device against the inner magnetostrictive body with a predetermined force. The pressure force extends in the direction of contraction and perpendicular to the direction of expansion both caused by the influence of a magnetic field on the magnetostrictive body and results in a prestress acting in the direction of contraction in the magnetostrictive body. The predetermined pressure from the pressure means exerted on the clamping device and thus on the magnetostrictive body is adjustable by means of a resilient force or mechanical setting means.

Title: Injection tube and method for placing a ground anchor
Inventor: GRUBER HEINZ
IPC: E21D20/00
Filed: 1992-05-30
Abstract: Abstract Injection tube and method for placing a ground anchor An injection bore anchor (1) intended for use with rock which has particularly low cohesive properties is characterised in that at least two injection valves (11) are arranged in the front region of the injection bore anchor (1), i.e. in the region adjacent to the bore-crown (8) and the said injection valves (11) function like non-return valves, by means of which it is possible for the grout suspension issuing from a longitudinal channel running through the injection bore anchor (1) to flow out but not the reverse.  In order to place the injection bore anchor, the injection bore anchor (1) is initially used as a bore rod, wherein a flushing fluid is guided by way of the longitudinal channel and the said flushing fluid flows out by way of the bores in the region of the bore-crown (8).  Subsequently, a grout suspension is introduced by way of the longitudinal channel into the bore hole for the purpose of filling the bore hole, wherein subsequently the residual grout suspension located within the channel is displaced as far as the region of the bore-crown (8) by means of a displacement body introduced into the channel.  By way of a grout suspension being introduced again after the initial setting of the grout suspension  in the bore hole and the said grout suspension now flowing out by way of the injection valves (11), exerting a cracking open effect on the grout located here and/or penetrating in the still existing cracks and gaps, the bore hole in the region of the bore hole bottom and the surrounding rock is expanded and thus the size of the region penetrated by the grout is considerably increased, as a result of which it is possible to secure reliably the position of the injection bore anchor (1) in the surrounding rock.
