Patent CA-1281755-C (CA)
Title: Pressure limited differential pressure switch
Inventor: BROWN GEORGE E
IPC: H01H35/38
Filed: 1987-10-28
Granted: 1991-03-19
Abstract: ABSTRACT OF THE DISCLOSURE        A differential pressure switch includes a housing which carries a switch assembly which is actuated by movement of a differential pressure responsive piston slidable within the housing.  The piston shifts in response to pressure differentials between the pressure levels in the chambers defined between the ends of the piston and the corresponding ends of the housing.  The piston includes a pressure responsive stop that responds to pressure levels above a predetermined pressure level to engage the housing to thereby prevent shifting of the piston and actuation of the switch assembly regardless of the pressure differential across the piston, thereby limiting operation of the pressure switch to pressure levels below the predetermined maximum pressure level.

Title: Continuous damping means for off-set printing machines
Inventor: TERZUOLO GIANCARLO
IPC: B41F33/00
Filed: 1988-08-16
Granted: 1992-01-21
Abstract: ABSTRACT OF THE DISCLOSURE         The excess of damping liquid taken from the vessel 3 by the fountain roller 4 which rotates in the direction indicated by the arrow 6 is removed by the wiper element 9 formed of a body made of elastic material of circular cross section housed in a longitudinal groove in the rigid support bar 11.  The fountain roller is rotated by the dc motor 5, the speed of which is adjusted by pulses coming from the processor 23 under the influence of the signal transmitted to the processor by the speed detector 23 which is located on the shaft of the plate roller 1.          The speed can also be influenced by other signals transmitted to the processor, for instance from the keyboard 30 where it is possible to enter data relative to different characteristics of the equipment and of the damping liquid, for instance according to its viscosity.  The fountain roller transfers the liquid to the duct roller 7, the peripheral speed of which is equal to that of the plate roller, or to the first of the rollers of the inking system.         The wiper element is subjected in three zones of its length, preferably separated by equal spaces, to the thrust of the rods of three membranes actuated by pressure fluid.  To each of these membranes can be applied a pressure which is adjustable by means of a regulating device 21 controlled by pulses coming from the processor which are created therein based on information transmitted to said processor, for instance by detectors of the relative humidity of the air and the temperature on the opposite sides of the machine and at the intermediate part thereof or in response to signals transmitted to the processor by the scanner 25 of the plate at three different strips on the peripheral surface of the plate (FIG. No. 2).

Title: Crew oxygen mask with pneumatic comfort adjustment
Inventor: AULGUR CHARLES C
IPC: A62B7/14
Filed: 1989-02-24
Granted: 1992-04-21
Abstract: Abstract of the Invention A  respirator  especially  constructed  for flight crews has a harness strap which can be in-flated to a somewhat rigid, self-sustaining orienta-tion to permit one-handed placement of the respira-tor over the wearer's head.  Once the respirator is in place, release of a lever for inflating the strap deflates the latter to a orientation sufficient to cause the resilient strap to tightly press a peri-pheral seal of the respirator mask against nose and mouth areas of the user's face.  A comfort adjust-ment to relieve strap tension permits selective reinflation of the strap to a somewhat smaller value than necessary for initial donning of the harness, and the limited reinflation pressure is sufficient for causing the mask to seal against the face during pressure  demand  breathing.    In  instances  where pressurized breathing is needed, however, pressure within the strap is automatically released so that the strap presents sufficient bias to hold the mask against the face without oxygen leakage therepast.
