A steam shower is provided for supplying steam to a web in a paper machine. The steam shower includes a diffuser assembly mounted to the cross-beam for movement in the direction of the longitudinal axis of the cross beam. The cross-beam defines an interior steam header for connection to a source of steam. The diffuser assembly includes a plurality of separated steam compartments. The diffuser assembly may be part of a steam provision assembly that is also mounted to the cross-beam for movement in the direction of the longitudinal axis of the cross beam. In addition to the diffuser assembly, the steam provision assembly includes a second steam header and steam valve modules.

One or more actuator driven devices on a sheet forming machine receive power and engage in bi-didrectional communications with one or more quality control systems either by having no physically connected cables to transmit the power to the actuators and no physically connected cables used for the bi-directional communications; or contactless power and communication on a power cable; or a cable connected from the power source to the actuators to provide both power and bi-directional communications; or power is provided to the actuators by a cable and the bi-directional communications are wireless.

Suspension apparatus (10) for the front end of a motorcycle, bicycle, or like vehicle (11), having a brake (12) on the front wheel (13), comprising a suspension device (14) comprising a pair of telescopic members (27,28) connected to permit relative movement between the frame (15) of the vehicle (11) and the axle (16) of the front wheel (13), a linkage (17,18,20) and a hydraulic cylinder (19) for converting friction force (at 17) from any substantial braking (at 12) of the front wheel (13) into an approximately proportional hydraulic force (at 21), and fluid connecting lines (22,24) with adjustable damping means (23) for applying the hydraulic force (from the fluid 21) to the suspension device (14), at an end surface (29) of a piston (35), so as to oppose and at least largely counterbalance the inertial force thereto resulting from the braking action, and thus to at least largely eliminate diving by the front end of the vehicle (11) when the brake (12) is applied.

A linear weight actuator includes a clamp assembly adjustably connecting the power screw to the output spindle. The assembly includes an integrally formed key, riding in a slot formed in the actuator housing, which obviates the need for a separate key element. A mounting plate is adjustably clamped to the actuator housing, by a threaded mounting nut, such that the plate may be conveniently rotated relative to the housing. A linear bearing disposed in the mounting nut provides lateral support for the output spindle at a point spaced from the clamp assembly. A clamping ring encircles a thinned segment of the power nut and urges it against the power screw to prevent backlash.

A diving suit is provided with neck and wrist opening seals each in the f of a right cylindrical annulus of open celled resilient foam rubber having a through passage a portion of which is cylindrical and a portion of which is frustoconical so that part of the annulus wall is of uniform thickness and part is tapered. The tapered portion overlies a conical, opening defining edge portion of the suit fabric and a band of non-stretch tape fixes the tapered edge portion of the annulus to the fabric while allowing the thicker wall portion to expand and contract as a head or hand is pushed through. The outer cylindrical surface beyond the tape is adapted to cooperate with a mask hood or glove cuff.

A pneumatic stepper motor weight actuator captures the advantages of polymeric harmonic gears while occupying less space and eliminating the problems associated with air entrapment in the stator grooves. Air entrapment is eliminated by providing orificed air passages from the bottom of the longitudinal stator grooves to the center stator hole. Advantageously, the actuator includes a rigid gear comprising a toothed polymeric sleeve adhesively bonded inside a metal cup.
