Abstract: A brake device has a housing in two parts releasably connected together by bolts. Co-operating pressure fluid passages in the two housing parts communicate pressure fluid from a source to actuators within the housing, and include separable plug and socket connectors located on the respective housing parts so that separation of the housing parts effects disconnection of the actuators from the pressure fluid source. A non-return valve is arranged to close on separation of the housing parts and to be opened again by the plug connector. An electrical connection to an electrically powered cooling fan can be similarly broken when the housing parts are separated.

Abstract: A cushioned braking system for cushioning the impact of a moving vehicle for amusement for children. The braking system comprises a double ended air cylinder having a first cylinder end and a second cylinder end. A first head member and a second head member close the first and second cylinder ends, respectively. A first piston rod extends axially outward from the cylinder through the first head member. A first piston is on the first piston rod within the cylinder. A second piston rod extends axially outward from the cylinder through the second head member. A second piston is on the second piston rod within the cylinder. A spring assembly resiliently connects the first piston to the second piston within the cylinder. The spring assembly serves to bias the first and second pistons toward a reference position. The cylinder also has a vent for controlling air flow within the cylinder.

Abstract: A liquid concentration detecting apparatus which permits a real-time and high-accuracy detection of concentration of a liquid (particularly an etching or cleaning solution) used in a semiconductor plant, with a simple configuration at a low cost. The liquid concentration detecting apparatus 1 has a cell 2 to which a liquid is supplied, and a projecting section 4 and a receiving section 5 arranged opposite to each other in a direction at right angles to the axial line of the cell. A light of a prescribed wavelength is projected from this projecting section 4 through the liquid in the cell 2 to the receiving section 5, and the concentration of the liquid is determined by detecting the amount of light received by the receiving section.

Abstract: A bypass procedure for connecting a bypass conduit to a blood vessel to channel a flow of blood around an occlusion. The procedure involves attaching a bypass conduit to a portion of the blood vessel at first and second locations. A collar is utilized to suture the graft to blood vessel. A punching device is inserted into one of end of the bypass conduit. The punching device preferably includes a punch and a block. The block is inserted through a cut formed in the blood vessel wall. Concomitant actuation of the block and punch toward one another severs a section of the blood vessel wall to form a channel into the bypass conduit. The present invention also discloses preferred implements for use in the bypass procedure. A cutting device can be utilized to form the cuts in the vessel wall and may be either integral with or separate from the block. In one embodiment, the block is expandable between a collapsed state and an expanded or inflated state.
