    摘要: A method for measuring the machinability of a material includes piercing a hole through a material to be tested while simultaneously measuring a pierce time duration, T, of the piercing step, and calculating a machinability number from the pierce time duration. Also provided are methods for determining the machining speed of a material and for machining a material which calculate a machining speed for a material based upon the machinability number of the material. The methods used to measure the machinability number and calculate a machining speed for a particular material can include any combination of machining operations, including abrasive water jet cutting processes. Also provided is an apparatus which detects the time duration a piercing force takes to create a pierce-through condition through a material. The apparatus includes any of a pressure sensor, an acoustic sensor, an optical sensor, a load cell, a mechanical switch, or any combination thereof, to measure the pierce-time duration.

    摘要: A device for use within the backhead of a down hole percussive drill, for removing debris from a drillhole, includes a flow control member in the drill backhead for inducing cyclonic flow of percussive fluid, to concentrate the heavier water and other matter away from the lighter percussive gases, a separator in the backhead that separates the water and other matter, passageways in the backhead for ejecting the separated water and other matter, a sealing member for sealing the backhead passageways against back flow of debris from the drillhole annulus, and an indexing member for positioning the separator so as to permit a pre-selection of flow amounts of removed water and other matter.

    摘要: A steering shaft, in a lockable steering column, consists of a hollow cylindrical tube (30) mounted in bearings (21, 22) within a steering column sleeve and may have upper and lower ends formed for connection to a steering wheel and to a steering gear box, respectively. An axially disposed lock slot (35) is provided in the wall of the hollow tube (30) for locking the steering shaft against rotation when engaged by a lock pawl (55) from a lock housing in the steering column, the lock slot being a recess (40) formed without breaching the wall of the hollow cylindrical tube (30).

    摘要: A hydraulic turbine that includes a turbine runner that reduces fish mortaliy as the fish pass through hydroelectric power stations. The turbine runner includes at least two turbine runner blades included in a corkscrew configuration. Significantly, the corkscrew blades are exceptionally long in the overall direction of fluid flow through the turbine. In accordance with preferred embodiments, fluid flow to the runner from the inlet is mixed flow; the fluid flow at the outlet is directed substantially axially. In certain highly preferred embodiments of the turbine runner: the ratio of the sum of the leading edge lengths to the runner diameter is less than 1.0, the ratio of each blade running length to the runner diameter is greater than 1.0, the ratio of each blade running length to the respective blade width is greater than 3.0, the ratio of the axial length to the runner diameter is greater than 0.6, and the turbine runner (at its best efficiency point): is at least 80 % efficient and achieves a rate of pressure change less than 80 psi/second along substantially the entire length of the runner blades, and the minimum absolute pressure maintained along the main fluid flow path is 4 psia when the trailing edges are located at a tailwater elevation.

    摘要: An adjustable vehicle steering column clamping mechanism for a rake and reach adjustable steering column includes a steering column support bracket (3) which has two flanks (3A) extending on either side of a steering column outer tube (9), each flank (3A) incorporating a slot (3B) to permit rake adjustment. A reach adjustment bracket means (8) has two flanks (8A) which extend on either side of the tube (9) and lie adjacent the flanks (3B) of the bracket (3), the flanks (8A) also having slots (8B) extending parallel to the tube axis (9A) for reach adjustment. The flanks (8A) are spaced from the tube (9A) so as to accept heads (10A) of clamping bolts (10) operated by a handle (9) acting on associated clamping parts (12) mounted on the bolts (10). The arrangement enables the bolts to be located on a substantially on-centre line passing at right angles through the axis of the steering column.

    摘要: An angular contact bearing is mounted within a housing (26) and a shaft (24) is positioned within the bearing such that an annular space is provided between the bearing and the shaft. A mounting ring (32) of elastomeric polymer is positioned over the shaft and against a bearing inner ring (34) such that a portion of the mounting ring is between the bearing inner ring and the shaft, centring the shaft within the bearing and reducing radial freeplay. The mounting ring is compressed axially, against the bearing, such that the mounting ring deforms and resiliently spreads radially outwardly and provides a preload on the bearing balls.

    摘要: A dispensing apparatus (10) for dispensing a material including a valve assembly (20) comprising: a valve member (22) movable in a reciprocating fashion along an axis, where the valve member (22) includes a stem (28) having at least one material transfer recess (30) provided on the stem (28) and a tapered dispensing end (24) having an angle of taper. The valve member (22) is movable between a first position where a discrete toroidal mass of material to be dispensed is formed at the dispensing end (24) and a second position where a discrete toroidal mass of material to be dispensed is not formed at the dispensing end (24). The dispensing apparatus (10) also includes a material dispensing assembly comprising having a fluid knife for moving the discrete toroidal mass to be dispensed from the dispensing end (24) away from the dispensing end (24) when the valve member (22) is in the first position. The fluid knife is supplied substantially parallel to the angle of taper of the dispensing end (24).
