Abstract: There is disclosed a pilot operated valve which includes a valve body, a main valve having a main valve member controlling fluid communication between an inlet port and an outlet port, a pilot valve including a vent passage sensing downstream pressure to open and close the main valve member as the sensed pressure is above or below a predetermined pressure, and selectively operable override means to suspend pilot operation of the valve. The override means may be means to occlude the vent passage and thus close the main valve, means to open the vent passage to atmosphere and thus open the main valve, or means to bypass the main valve.

Abstract: There is described an exercise measuring device intended to be attached to a person's body or clothing to indicate that a predetermined level of activity is being maintained. In the form of the device shown a pendulum is mounted for movement between two adjustable stops so that movement of the person's body causes the pendulum to impact alternately on the stops. Electronic or electrical circuitry may be included to count the impacts on one or both stops, and audible or visible signals may be given when predetermined numbers of impacts have been registered.

Abstract: This invention relates to containers and methods of, and apparatus for, manufacturing containers. A container in accordance with the invention includes four walls (202-205, FIG. 1, or 301-303 and 305, FIG. 4), and a base (201, FIG. 1, or 306, FIG. 4). The base is constituted by two flaps (206 and 207 or 307 and 308) arranged so that they can be moved between a first position in which the container can be folded flat, and a second position in which they hold the four walls in a generally rectangular formation.The container may be manufactured by sealing six boards (4, 5 and 6) between two webs of PVC material drawn from supply rolls (50 and 51). The sealing is carried out by means of a welding process which also forms the boards (4 and 5) into hinged pairs. In further welding processes, boards (6) are hingedly connected to the boards (4 and 5). Finally, two pairs of boards (4 and 5) are hingedly connected together to form the four walls of the container. In the welding process, a raised portion (123, FIG.

Abstract: A clutch assembly is preferably designed as a multiple-disc clutch. Rotating with one clutch half (22) is a clutch-engaging piston (26) and a pressure chamber (25) into which fluid may be admitted. Against the force of a spring (29), the piston may be subjected to the fluid pressure which is generated in the pressure chamber (25) and which is dependent upon the rotational speed. Arranged beside the pressure chamber is a fluid reservoir chamber (37), communicating with the pressure chamber (25) via connecting conduits (44, 45). With the aid of a control element (48) the filling of the pressure chamber (25) with fluid from the reservoir chamber (37) is controlled during a start-up process. In this manner, the engagement of the clutch assembly is controlled. Thereby delivery of fluid from outside of the clutch assembly is unnecessary.
