Patent CA-1304423-C (CA)
Title: Air spring suspension system with dual path isolation
Inventor: WEITZENHOF DAVID A
IPC: F16F9/54
Filed: 1988-10-17
Granted: 1992-06-30
Abstract: ABSTRACT OF THE DISCLOSURE        A suspension system for a vehicle having a shock absorber strut with a reciprocal piston rod located within a cylinder, and attachments for securing the piston rod and cylinder to spaced parts of the vehicle.  An air spring includes a rigid annular canister mounted on the piston rod by a resilient rotatable mount.  The canister forms a fluid pressure chamber in conjunction with a flexible diaphragm, one end of which is sealingly connected to the cylinder by an annular rigid sleeve which forms an air spring piston.  The flexible  diaphragm has inner and outer radially spaced portions connected by a rolling portion.  A rigid member resembling a cutaway can is mounted on the rigid canister portion of the air spring and extends about a predetermined portion of the outer portion of the flexible diaphragm and restrains outward expansion of said portion.  Restriction of the outward expansion of only a portion of the flexible diaphragm exerts a lateral force on the strut to counteract the unbalanced lateral forces acting thereon due to the offcenter mounting of the strut with respect to the point of contact of the vehicle wheel with the pavement.  The suspension system furthermore provides dual path isolation for separating the canister from the vehicle by a primary elastomeric isolator ring and from the strut by secondary elastomeric bushings mounted on the strut, which bushings also provide an upper air seal for the fluid pressure chamber.

Abstract: ABSTRACT       A marine fuel injection system for a two cycle crankcase compression internal combustion engine includes a puddled fuel return line between the crankcase and a vapor separator.  A shut-off valve in the puddled fuel return line is closed at high engine speed to prevent the flow at a high rate of a substantially gaseous  medium to the vapor separator, to prevent fuel foaming otherwise caused thereby in the vapor separator and which would pass through the vapor vent line to the induction manifold, causing an over-rich condition at high engine speed.  At low engine speed, the shut-off valve is open, permitting flow of puddled fuel to the vapor separator, which flow is substantially more liquidic and at a lower rate.

Abstract: ABSTRACT    A method for remotely monitoring conditions such as carbon monoxide or methane gas concentration, longwall roof support pressure machine parameters or uncut coal, trona or potash layer thickness in a natural resource mining system such as a longwall or continuous mine system.  The method utilizes a plurality of sensors connected to low magnetic moment transmitters, e.g. 0.1 ATM2, or high magnetic moment transmitters, e.g.  2.5 ATM2, that transmit collected data during multiple short burst transmission periods.  Prior to transmission, the data is converted to a digital word format.  An algorithm in the transmitter microcomputer ensures that random time intervals exist between data transmission bursts thus preventing a data transmission clash at the central receiver.  A microcomputer algorithm in the central receiver protects against data contention caused by simultaneous transmission from several sensors.  The data is transmitted to the central receiver either through a natural waveguide pathway or through a utility conductor that is magnetically coupled to the transmitter and central receiver by properly oriented electrically short magnetic dipole antennas.  The method can be used, for example, to automatically control the positioning of a plurality of longwall roof supports or to transmit data from a longwall drillhead, along the drill rod, to the central receiver.  Data can be communicated between a remote location and a surface area by utilizing a system of repeaters inductively coupled to a utility conductor.  Use of the repeater system permits operation of mining machines from a surface computer.

Abstract: DIGITAL TO AMPLITUDE MODULATED ANALOG CONVERTER                 ABSTRACT OF THE DISCLOSURE      A low cost, high quality converter for generating an amplitude modulated signal in response to a sequence of digital words representing a modulation signal, such as a video image.  The converter receives the sequence of digital words at an input rate.  The input sequence of digital words is combined with a sequence of factors at a  sample rate  to generate  a  second  sequence  of digital  words  at  the  sample  rate  representing  the amplitude modulated signal.   The second sequence of digital  words  is  then  converted  to  the  amplitude modulated  signal.    The  sequence  of  factors  is  a sequence of cosines of the carrier frequency at the carrier phase angle of 45,  135, 225 and 315 degrees.          The value of these cosines are +.707,  -.707,  -.707, +.707 respectively.   These values are normalized to 1 so that they become a sequence of +1, -1, -1, and +1.          Multiplication  by  the  sequence of  factors  is  thus carried out by alternately inverting the input sequence of digital words at one-half the sample rate.

Abstract: A thermal energy storage medium comprising a hydrophilic polysaccharide supporting an inorganic salt that is capable of transforming from one phase to a less hydrated phase absorbing latent heat, and releasing this latent heat upon the reverse transformation. The polysaccharide, preferably Xanthan Gum, may be incorporated in concentrations of 0.05% to 3% together with a nucleating agent in order to form a material that transforms when cooled back to the transformation temperature, or in greater concentrations of 1% to 5% without a nucleating agent to form a material that may be cooled below the transformation temperature without transformation taking place, and stored at ambient temperature whilst still storing the latent heat until activated.The medium is gelled in the less hydrated phase and in some embodiments the gel is pseudoplastic thus enabling it to be poured into chambers of an energy storage device, and then regain its original viscosity at rest.
