Patent CA-2108051-A1 (CA)
Inventor: ROBERTSON RUSSELL E
IPC: F15B20/00
Filed: 1993-10-08
Abstract: A hydraulic pipeline valve operating system (10) includes a tank (12) which holds a quantity of unpressurized hydraulic fluid.  A pump (14) provides that fluid under pressure to a valve actuator (11).  The valve actuator has an actuator cylinder (40) having a piston (42) which is operatively connected to the pipeline valve (28). The fluid under pressure moves the piston (42) of the cylinder (40) to compress a spring (35) to open the valve (28).  When the piston (42) of the cylinder (40) ceases movement, continued pumping moves a piston (53), of a smaller diameter than the piston (42), which also acts against the spring (35).  An indicator rod (60) gives a visual indication of the position of the piston (53) and when it is at approximately its midstroke location, pumping of the fluid is terminated and the actuator (11) is set. Should ambient temperature conditions change, the piston (53) moves to accommodate such changes thereby leaving the piston (42) unaffected.  When a pressure sensing valve (22) senses a predetermined pressure change in the fluid in the pipeline, a dump valve (23) is opened permitting the pressurized fluid in the system (10) to be transferred back to the tank (12).  The spring (35) can thus move the piston (42) to close the pipeline valve (28).

Filed: 1993-07-30
Abstract: An audio enhancement sys-tem (20) and method of use with a sound system for producing pri-mary sound from at least one main loudspeaker (23) located at a main position. The audio enhancement system (20) comprises at least one wireless transmitter (30-N), time delay circuitry (36-N), and plural augmented sound producing sub-systems (32-N). Each sound subsys-tem (32-N) is a portable unit ar-ranged to be carried by a person lo-cated remote from the main loud-speaker (23) and includes a wireless receiver (48) and an associated transduce device, e.g., a pair of stereo headphones (60). The trans-mitter broadcasts an electrical sig-nal which is representative of the electrical input signal provided to the main loudspeaker (23). The broadcast signal is received by the receiver (48) and is demodulated and amplified to drive the transducer (60 or 62) so that it pro-duces augmented sound substantially in synchronism wit the sound arriving from the main loudspeaker (23). To achieve that end the time delay circuitry (36-N) delays the electrical signal which is provided to the transducer (60 or 62) for a predetermined peri-od of time corresponding generally to the time period it takes for the primary sound to propagate through the air from the main loudspeaker (23) to the remote location at which the person is located.
