Abstract:
The invention concerns a method of drawing condensate off from compressed-gas, e.g. compressed-air, systems, the method calling for: 1) a trap (20) in which condensate collects during operation of the system, the trap (20) having an outlet (22) through which the condensate which collects can be drawn off; 2) a purging device (24) which is connected to the outlet (22) and which has (a) a sensor intended to detect the presence of condensate in the purging device, (b) control electronics (28) connected to the sensor (26) and including a timer circuit (30) and (c) a valve controlled by the control electronics (28) and which, influenced by the sensor (26), either shuts the purging device (24) so that no condensate can escape through it or opens it each time the condensate level rises and the sensor (26) switches over from indicating "no condensate" to indicating "condensate present", thus starting the timer circuit (30). On expiry of the time defined by the circuit, the valve is opened until the sensor (26) indicates "no condensate" again, when the valve closes the purging device (24) again.
Abstract:
The invention relates to a condensate discharge device for compressed gas systems, comprising a housing (21), which has a condensate collecting chamber (22) that can be connected to the compressed gas system by means of a condensate feed (23) and which has a condensate drain (24) that can be closed by means of valve assembly (25), and comprising a tubular body (32) protruding into the condensate collecting chamber (22) for accommodating at least one electronic filling level measuring device (31), by means of which the condensate filling level in the condensate collecting chamber (22) can be detected, wherein the housing (21) can be mounted in a first, vertical mounting position and a second, horizontal mounting position and the longitudinal axis of the tubular body (32) extends at an angle to the condensate feed direction (34).
Abstract:
A moisture control system (10) generally comprising a collector element (20) is configured to be incorporated into a structure to control moisture condensation on the interior and exterior of the structure. The collector element (20) encourages condensation on its surface (21A, 21B). The control system (10) includes a channel (36, 36', 37) in fluid communication with the collector element (20) to direct the condensed liquid away from the control element (20).
Abstract:
A drain valve of an air braking system for vehicles has a drainage piston (54), a main sump (59) and auxiliary sump (61). Moisture passes from the main sump (59) to the auxiliary sump (61) in response to pressure at a signal port (27) which closes off air supply through ports (24, 26). A reduction in pressure at signal port (27) causes the ports (24, 26) to be reconnected and allows moisture to be expelled through drainage outlet (48).

Abstract:
The present invention discloses multiple loop reactor wherein one of the settling legs transferring polymer product from one loop to a further loop can be taken out of service or reopened without interfering with the operation of said multiple loop reactor.
Abstract:
A pressure operated normally closed control valve (40) operates to open at a predetermined pressure between the system minimum and maximum pressures to open the valve (40) and allow the discharge of condensate from the system which has a source of pressure (16) to provide a minimum and a maximum pressure. The system is subject to the formation of condensate. There is an inline filter (36) at the inlet end of the valve (40) and a discharge nozzle at the outlet end of the valve (40). The entrance to the discharge nozzle may also have a filter (45). The assembly can also be arranged so that the control valve (40) is normally open and operates to open at a predetermined pressure at or below the system minimum pressure whereby condensate is removed, and to close the valve (40) and prevent the discharge of condensate from the system when the pressure falls below the predetermined pressure.
Abstract:
A drain valve (38) removes liquid from a compressed air system (20) whenever cycling pressure of the system (20) reaches either a preselected high drain pressure or a preselected low drain pressure at an inlet port (39) of the valve (38). An inlet face (79) of a piston (78) of an adjustable pressure valve assembly within a valve body normally seals the inlet port (39) when there is no pressure. The piston (78) is located within a portion of a central cavity of the valve (38). The piston's inlet face (79) is of a size which allows the force of the adjustable pressure valve assembly to be overcome by a pre-selected high drain pressure at the inlet port (39).
Abstract:
An improved relay valve (10) having a supply port (16), a delivery port (18), an exhaust port (20), a control port (17), a relay piston (14) controlling communication between the supply port (16), the delivery port (18), and the exhaust port (20) in response to a pneumatic signal applied to the control port (17) and including a passage (40) extending through the piston (14) to the exhaust port (20) for draining to atmosphere moisture and other contaminants which build up on the top of the piston (14). A diaphragm element (30) having a cylindrical protrusion portion (36) is disposed in the piston (14) above the passage (40) to act as a check valve and seal the passage (40) when a pneumatic signal is applied to control port (17). The diaphragm element includes a top resilient portion (32) which serves as a spring to open the drain passage when no signal is applied to control port (17). Two flat areas (34) are provided on the top resilient portion (32) which prevents the diaphragm element (30) from prematurely sealing the drain hole (40). The cylindrical protrusion (36) keeps the diaphragm element (30) properly aligned in the tapered bore (44) leading to drain hole (40). A retaining ring (42) keeps diaphragm element (30) within the bore (44).
