Title: Automatic bleed valve for pressurized reservoir
Inventor: CENCULA MICHAEL A
IPC: F16K24/04
Filed: 1993-08-31
Abstract: An automatic bleed valve 34 for bleeding air from a pressurized liquid reservoir includes a piston 4 in a piston chamber 25 located in a flow channel leading from the reservoir. A first orifice 6 is provided in a passage 24 through the piston 4, and the piston 4 is urged upstream by a resilient spring 8. A second orifice 16 downstream of the first, is located in the flow channel. When gas is expelled from the reservoir, the resilient spring 8 will retain the piston 4 in an equilibrium region, allowing the gas to be bled from the reservoir through the flow channel. When liquid begins to flow through the flow channel, the pressure differential over the piston 4 increases, because the pressure drop across an orifice is greater for a liquid than a gas, and this causes the piston 4 to move against a seat 23 of a poppet 5 and seal off the flow channel and the hydraulic reservoir. The diameters of the orifices may be chosen to maximize the increase in pressure differential. <IMAGE>

Title: Remotely-operated self-contained electronic lock security system assembly
Inventor: TISCHENDORF ANDREW
IPC: E05B49/00
Filed: 1996-05-28
Abstract: A keyless locking mechanism for use in a door. An operator activates the system by means of a portable remote handheld controller (900, 1000) which transmits coded signals to a door lock device (29). The electronic and electromechanical device components are mounted within the void or hollow portions of existing door locking apparatus, such as within the hollow interior doorknob (30), or hollow cylindrical sleeve latch actuators, or beneath the interior rose or escutcheon plates. A sensor (510) or receiver/antenna is mounted within the outer doorknob receives and forwards the coded signals to a processor which compares them with a stored signal. If a match is made, the processor generates control signals for the electromechanical device, which acts solely along or about the locking axis to enable or disable the door locking assembly, according to the command initiated by the operator.
