Patent CA-2203603-A1 (CA)
Title: Universal pneumatic brake control unit
Inventor: WOOD JAMES A
IPC: B60T13/66
Filed: 1997-04-24
Abstract: A universal unit controls the brakes of a truck of a rail vehicle.  The unit includes a service valve, an emergency valve, a variable load relay valve, a release valve, a local control means, a solenoid driver means and a brake assurance means.  The service valve when opened provides a first control pressure.          The emergency valve when opened provides a second control pressure.  In response the control pressures, the variable valve provides to the brake cylinder a load compensated pressure proportional to air spring pressure.  The brakes then apply to the wheels of the truck a force that accounts for the load borne by the rail vehicle.  The release valve when opened prevents the variable valve from providing the load compensated pressure.          The local control means controls the control pressures according to a brake force command signal and a control pressure feedback signal.  The solenoid means operates the valves in response to valve command signals received from the local control means.     The brake assurance means operates in a standby mode in which the local control means controls the release and emergency valves via the solenoid means or in an intervention mode in which  it  does  not thereby  assuring that the  release  and emergency valves open.   This enables the variable valve to provide the brake cylinder with the load compensated pressure and therefore apply the brakes.   The brake assurance means assumes the intervention mode in response to a loss of power or to a predetermined set of conditions.

Title: Microporous fabric containing a microbial adsorbent
Inventor: CARTWRIGHT WILLIAM FRANCIS
IPC: D06M11/38
Filed: 1996-05-29
Abstract: Disclosed is a fabric which includes a microbial adsorbent and which is capable of providing a microbial barrier while still being able to allow passage of water vapor. The fabric is formed from a plurality of fibers which define at least one microporous passageway which allows communication, through the fabric, between its respective first and second surfaces. In particular, a portion of the microporous passageway is defined by the microbial adsorbent so that microbes attempting to pass through the fabric via such a passageway must pass in close proximity to the microbial adsorbent. This arrangement allows the microbial adsorbent to interdict the microbe by adsorbing it. Passage of the microbe through the fabric is therby prohibited. Laminates of the fabric with other materials are also disclosed.
