Abstract: There is provided a tube end configuration for joining two hollow tubes end to end, the novel joint comprising a tapered end on one tube, which end fits into the untapered end of another tube forming a variable length tubular pipe. The untapered tube end has one or more protrusions (ridges) extending inwardly from its inner wall while the tapered end has one or more complementing indentations (recesses) extending inwardly from its outer wall. The ridges engage the recesses when the tubes are joined together. One or both of the tubes also have several longitudinally aligned slots located within the tube ends that overlap whereby spring leaves are defined which can flex resiliently to allow the ridge(s) to ride over the taper and fixedly lodge in the recess(es) as the tubes are slid together.

A flexible sleeve is provided surrounding each fluid passage which, when pressure is supplied to its exterior, will collapse about a central fitting in each passage preventing flow from inlet to outlet openings in the central fitting. Pressure in the chamber surrounding the flexible sleeve is relieved when the dental handpiece is removed from its holder and is restored when the handpiece is returned to its holder.

Abstract: An integral window unit comprising a sill member, a header member and a pair of jamb members interconnected to form a generally rectangular window frame. The jamb members have first and second pairs of track means each pair of which slideably receives a prime window sash and third and fourth pairs of track means each pair of which slideably receives a storm window sash. The distance between the track members in the first pair is greater than the distance between the track members in the second pair which in turn is greater than the distance between the third pair which is greater than the distance between the fourth pair. At least one pair of track means is in overlapping relationship with the adjacent pair of track means. A thermal barrier is provided in the window frame between the second and third pair of track members to minimize heat loss therethrough and a fifth pair of track means is provided adjacent the thermal barrier for slideably receiving a screen member.

Abstract: An inverted bucket steam trap having a two lever (30, 34) linkage mechanism between the bucket (18) and the valve member (28) which engages a valve seat (26) through which condensate is discharged. The first lever is connected to the bucket and the second lever carries the valve member. The linkage mechanism is arranged such that the second lever initially undergoes pivotal movement to disengage the valve member from the valve seat and then translatory movement to the fully open position of the valve.

Abstract: A valve body member and various insert assemblies usable with the body member to form steam traps of different types are disclosed in this application. The body member includes an internally threaded, generally cylindrical recess extending inwardly from an outer surface and terminating in an end face, an inlet passage communicating with the recess thrugh a passageway terminating in the end face of the recess, and a discharge passage also communicating with the recess. An annular rib is formed on the end face of the recess around the passageway and includes a surface on which is seated a first sealing ring clamped in place by a first bearing surface of the particular insert assembly used to form the steam trap; an annular seat is formed on the outer surface of the body member around the cylindrical recess and this seat receives a second sealing ring which is clamped in place by a second bearing surface of the insert assembly.

Abstract: A modulating flow control valve assembly having a bypass extending from the face of the valve through the valve and the means by which the valve is mounted within the valve body. As the valve moves within the valve body in response to fluid demands, the amount of bypass fluid is varied accordingly by controlling the amount of fluid permitted to pass through the bypass.

Abstract: A brush chipper having a guard (38) which is released to block the inlet (12) to the cutter (10) when an emergency condition is sensed. During normal operation of the chipper, the guard (38) is held out of the path of brush to the cutter (10). When a weight, in excess of a normal brush load, is sensed, as for example when the chipper operator is being drawn into the chipper, the guard (38) is released automatically and moves to block the inlet (12) to the cutter (10). This prevents the operator from being drawn into the cutter (10).

Abstract: The preferred embodiment of the invention disclosed herein includes a main check valve responsive to the rate of flow of fluid to a demand system and a bypass valve metering the flow of fluid to a bypass system. In the closed position of the main check valve, the bypass valve is in a fully open position whereby a predetermined minimum flow from a pressure source is maintained; in an intermediate position of the main check valve responsive to the predetermined minimum rate of flow thereacross, the bypass valve is closed and remains closed from the intermediate position of the main check valve to the fully open position. Operation of the bypass valve is controlled by fluid pressure from the inlet side of the main check valve which acts on a piston associated with the bypass valve and the buildup of pressure is controlled by a pilot valve.
