Abstract: ABSTRACT In a bellows-actuated thermostatic steam trap (A) having a bellows  (41)  carrying a valve member  (45)  of a valve (45/22) for opening and closing the trap, the bellows is disposed between connections (20/21 and 30/31) which are identical to one another so as to be selectively connectable in a steam flow line with the valve (45/22) disposed either downstream of, or upstream of, the bellows (41).  The trap includes  a  metal  housing  (11/12),  the  mass  of  which constitutes at least 70% of the mass of the trap. The trap operates, when connected with the valve disposed downstream of  the  bellows,  in  a  first  mode  in  which,  in  normal operation, the trap discharges condensate at a temperature close to saturated steam temperature.   When connected with the  valve  disposed  upstream  of  the  bellows,  the  valve operates  in a  second mode  in which  in  normal  operation condensate  is  discharged  at  a  temperature  significantly below steam temperature.  One or other of these modes can be simply obtained,  merely by selecting which way round the trap is connected in a flow line.

Abstract: ABSTRACT OF THE DISCLOSURE     A surgical case cart having a closed container supported on a chassis.  The closed container includes a pair of front door panels hinged to side door panels which in turn are hinged to side wall sections, so that the con-tainer can be completely opened with the front and portions of the sides being exposed by the door panels wrapping around the side and back.  The door panels are formed of single pan construction so as to avoid cracks and crevices, and yet exhibit rigidity of a double pan door construction.          The lower edges of the door panels provide a baffle effect to reduce the movement of contaminated air into the cart.          The top of the cart contains an overhang lip to prevent liquids from spilling into the container.  Stem mounted casters are utilized to avoid flat horizontal surfaces on which dirt can collect.  The intersection between the back, sides and chassis is constructed to avoid the possibility of collecting contamination and bacteria.  A door latch is provided which indicates whether the contents of the cart are sterile or contaminated.  Opening of the cart door panels nevertheless can be accomplished without the use of the operator's hands.  The cart construction therefore provides improved sterility, greater accessibility, and brings about easier maintenance.

Abstract: ABSTRACT             A circuit protecting against overspeed and overheating in a two-cycle engine having a capacitive discharge ignition system  which includes a charging coil in which voltage is induced when a magnet in the flywheel of the engine passes the coil.  A rectifier bridge is connected to the coil and a capacitor connected to the bridge.  An ignition coil and spark plug are associated with each cylinder of the engine.  An electronic switch is associated with each ignition coil and has a trigger which responds to an applied trigger voltage to conduct and discharge the capacitor through the ignition coil.  A trigger coil applies a trigger voltage to the triggers.  The protective circuit includes a control responsive to engine speed.  The control triggers one of the electronic switches to conduct and discharge the capacitor in response to a predetermined response speed.  A circuit responsive to operation of an engine temperature responsive switch reduces the predetermined response speed of the control to a lower response speed.  The lower response speed is maintained effective even if the engine temperature subsequently falls below the maximum engine temperature.  The circuit requires reduction of the engine speed to a speed below the lower response speed in order to restore the response speed of the speed responsive control to the predetermined speed.
