Patent CA-2047869-A1 (CA)
Inventor: BOCK WOJTEK J
IPC: G01L11/02
Filed: 1991-07-25
Abstract: The method is  for measurement of  pressure applied to a sensing element comprising a cholesteric liquid crystal being connected to multimode optical fibers for communication  with  a  light  source  and  a  device  for measurement  of  light  intensity.  The  method  resides  in guiding a light beam of predetermined wavelength generated by the light source toward a layer of the cholesteric liquid crystal using one of the multimode optical fibers. The light beam reflected by the layer is collected using another of the multimode optical fibers being connected to the device for measurement of light intensity. This device measures then the intensity of the reflected light beam, such that a value  indicative of the pressure as  a  function of the measured  intensity can be  carried out.  This method  is particularly well adapted for measuring pressure up to 100 MPa with a good linear response and sensivity for specific ranges of pressure useful in industrial applications.
Patent CA-2052121-A1 (CA)
Inventor: VANGERPEN HARLAN W
IPC: G01L5/13
Filed: 1991-09-24
Abstract: A draft force sensor includes a generally C-shaped member formed by a beam and a pair of lugs which both project to one side of the beam.  Coupling holes are located in each lug and the centers of the holes are off-set from the centerline of the beam.  One end of a flexible strap is fixed to one lug and the other end of the flexible strap is adjustably attached to the other lug.  Alternatively, both ends of the flexible strap may be coupled to the lugs by adjustable support devices which are pivotally connected to the beam.  The strap is curved and concave in a direction facing the beam and is biassed to urge the supports and the lugs away from each other.  A displacement transducer is mounted between the beam and the central portion of the strap.  The displacement transducer senses the change of distance from the beam to the "arch" of the strap and generates an electrical signal indicative of the force on the ends of the C-shaped member.

IPC: E01D11/04
Filed: 1991-10-15
Abstract: Bridge, in particualr of a very large span the deck of which is supported by stays deflected by passing over towers (21). Some of the stays (22) are anchored on the deck at two points of the deck situated on either side of a same tower (21), and the central part of a span between two towers is supported exclusively by other stays (25) which, after having been deflected at the top of a tower, are each anchored in an anchor block (26). The tensile stress to which the central part of the deck is subjected under the effect of these stays (25) direc-ted towards the tops of the two towers situated on either side of the span is compensated for by an axial compres-sive prestress.

Title: Explosion resistant, oil insulated, current transformer
Inventor: YAO EUGENE Y G
IPC: H01F38/30
Filed: 1991-11-07
Abstract: Abstract A  head  type  current  transformer  having  an aluminum head housing mounted on top of and supported by a porcelain  insulator.    The  head  housing  and  insulator together define an enclosure housing therein an, insulated, electrical component immersed in a liquid dielectric.  The transformer unit is rendered explosion resistant by having a shock wave attenuator located at least partially in the liquid in the vicinity of the juncture of the housing and insulator to reduce the force of a shock wave originating in the head housing below that which would cause fracturing of the porcelain insulator.  A selected area of the wall of the head housing is  also patterned to facilitate  its rupture in a predetermined area which is in the region of the highest voltage stress area.  A filler material of felt is also used to displace a portion of the oil dielectric at the area of weakness.

Abstract: ABSTRACT           Thermoplastics material corrugated sheet is provided having two outer layers sandwiching an inner structure, the mass of which is substantially evenly distributed between the outer layers.  The sandwiching or laminating process is conveniently carried out from three separate extruders providing a vertical fall of layers which are laminated by the use of at least some of heat pressure, and chill rollers against the vertical layers. On pressing the two outer layers together the inner structure crumples so that it is evenly distributed between the layers and does not form separate lumps which tend to hold the outer layers apart.  When the layers have been pressed together they may be heat sealed to close channels between the layers.          POLYBOX\10APP

Title: Method and apparatus for transmitting and receiving ofdm carriers
Inventor: MASON ARTHUR GORDON
IPC: H04N7/24
Filed: 1991-04-02
Abstract: ABSTRACT                 TRANSMISSION AND RECEPTION IN A HOSTILE INTERFERENCE ENVIRONMENT        A low power OFDM signal may be transmitted in an environment where it is subject to interference from other transmissions, e.g. broadcast television services. In a receiver interference is reduced by ignoring information modulating OFDM carriers at the frequencies corresponding to the carriers of the interfering transmissions; adjacent channel interference is reduced by ignoring data on OFDM carriers at the band edges and interference from third order intermodulation products is reduced by the ignoring OFDM carriers affected. Image channel interference is reduced by using an intermediate frequency for a first mixing process in the receiver such that the image channel interference affects OFDM carriers at frequencies which are already being ignored by the receiver.  Preferably no data is modulated onto OFDM carriers which are to be ignored by the receiver.  Preferably the modulation of the OFDM carriers is arranged so as to produce a real baseband representation of the OFDM signal.
