Abstract: A mechanical brake actuator comprises an output tappet (3) in screw-threaded engagement with a sleeve (7). In normal use, rotation of an operating member (17) by a rod or cable leads to axial advancement of the tappet (3) and sleeve (7) as a unit. Adjustment for wear is provided by rotating the sleeve (7) relative to the tappet (3) if, after a predetermined amount of rotation of operating member (17), the torque required to turn the sleeve (7) is below a predetermined value T. This is achieved by an adjuster comprising an input ring (25) coupled to an output member (29) by a torsion spring (28). The input ring (25) is coupled to operating member (17) by a lost motion connection (23,24) and output member (29) is coupled to sleeve (7) by a one-way clutch (30). After an amount of rotation of the operating member (17) predetermined by the lost motion connection (23,24) the operating member (17) entrains the input ring (25).

Abstract: In the variable speed V-belt drive of a combine harvester threshing cylinder, the driven sheave is torque-responsive, responding automatically to adjust drive belt tension according to the torque being transmitted. A linear hydraulic actuator, integral with the drive sheave, is used to adjust an axially movable sheave half with respect to a fixed sheave half so as to vary sheave effective diameter and hence driven speed. At any given speed setting, oil is trapped in the hydraulic actuator and oil pressure varies according to separating force between the halves of the drive sheave which in turn depends upon belt tension. A pressure switch, connected so as to sense the oil pressure, has a set point such that at a predetermined maximum (overload) belt tension, the switch is actuated so as to declutch or disconnect the drive sheave from its power source, thus protecting the threshing cylinder and drive components from damage.

Abstract: The drive train of the threadably advanced piston for a power caulker is provided with a quick release feature. When this feature is activated, the active portions of the drive nut of a lead screw in the drive train are disconnected from the lead screw so that internal pressure in the supply chamber of the cartridge may quickly equilibrate itself by pushing the piston and its lead screw backwards. Thus, dispensing may be smartly stopped and sharply curtailed, merely by releasing the trigger on the power hand tool and activating the quick release. Either of these acts may be performed first or both may be performed simultaneously. By preference, the quick release feature includes threaded claws that are cammed into and out of driving relation with the lead screw by a simple twist of the drive nut.

Abstract: A material moving apparatus, and in particular, a material moving pump such as a manure pump. The pump includes a pumping chamber defined by interior chamber walls, and a piston or ram mounted for reciprocation in the chamber. The ram has side walls generally in conformance with the shape formed by the interior walls defining the chamber. The side walls of the ram are slotted or provided with grooves which induce turbulence in fluid flow between the side walls of the ram and the interior walls of the chamber to inhibit backflow of material from a position in front of the ram to a position behind the ram. The pump thus operates efficiently to pump material of low viscosity or material of low density.

Abstract: An improved tool for cutting optical fibers by the scribe-and-break technique is provided. The tool has a scribing edge transversely directed with respect to, and normally spaced from, an arcuate convex fiber supporting surface. When moved normally with respect to the fiber supporting surface, the scribing edge defines a scribing plane. Spring members, located on opposite sides of the scribing plane, are compressed between the fiber supporting surface and a bearing surface, causing the optical fiber to be clamped between the spring members and the fiber supporting surface. This compression also forces the spring members to slide longitudinally along the fiber supporting surface away from the scribing plane, imparting an axial tensile stress to the optical fiber. The optical fiber is finally scribed by the scribing edge, resulting in propagation of a fraction over the cross section.

Abstract: A lubricating system which is completely self contained within the vacuum environment of an electric direct drive system for an ultracentrifuge rotor. The lubricating system also functions as a cooling means for an electric motor within the drive system by the use of a unique cooling feed tube in the central portion of the drive system. An orifice in the top of the cooling feed tube will control the head of the lubricating medium within the system. Specific design of the fit between the direct drive assembly and the drive housing in conjunction with the head on the lubricating medium will regulate the drip rate of the lubricating medium to the bearings. The use of the unique lubrication and cooling system maintains the close tolerances of the various elements such as the high speed bearings of the drive system because the temperature of the overall drive system is controlled.
