Abstract: A testing machine (10) reproduces road excited vibrations for the purposes of testing vehicle wheel support specimens (35), for example McPherson strut assemblies used in front wheel drive vehicles, the system permits force inputs of horizontal (62,64), steering (43), vertical (60), and wheel hop loads (215,216), as well as, optionally, simulating braking loads (66). The loading fixture (42) is compact, and substantially eliminates cross coupling of horizontal loading due to steering motion of the device, even though the steering motions p rovide for large steering excursions. The loading is tire coupled (155) to simulate actual conditions, including wheel hop that occurs during road travel, and further provides for inherent cross coupling compensation to permit easy instrumentation and very close simulation of road induced vehicle vibrations during the testing process. The entire steering linkage (22) can be tested, including tie rods, tie rod ends, and wheel suspension mechanism.

Abstract: A tool (10, 11) to be lowered down a borehole has a collar (13) with vanes (14) for sensing the transverse and torsional forces created by inflow at a perforation. The forces distort a bar (15) to which the collar (13) is attached by a spider (16) and strain gauges (18) provide corresponding signals. The total force on the collar provides an indication of the flow velocity through a perforation relative to the flow velocity up the wellbore at that perforation. Other embodiments utilise rings of temperature or capacitance transducers around the tool to sense field distributions from which information as to flow velocity and species can be inferred.

Abstract: A baling machine for hay has a variable volume baling chamber (50) defined by belts (42), and a completed bale is wrapped with net (76) which is advanced to the baling chamber, by feed rolls (84,86), past a cutting mechanism. 
     In order to avoid wastage of net for bales varying in size, the cutting mechanism (90) is triggered to cut the net (76) in a length which depends on the particular size of bale being made. To do this a sensor (130) moves with the expansion of a piston and cylinder unit (68) controlling the size of the baling chamber (50), and this movement is transmitted through a draw line (128) to a spring loaded abutment arm (120) which is thereby also shifted in accordance with bale size. A peg (122) on a wheel (112) is maintained in contact with the arm (120) until the wheel is driven by the feed rolls (84, 86) on take-up of net (76) into the chamber (50). The peg (122) then traverses a distance, determined by its starting position against the arm (120), to release the cutting mechanism (90) whilst the net (76) is still being fed to the chamber (50). Thus the length of net (76) which is cut will depend on bale size.

Abstract: An atomizing nozzle assembly is provided having an outwardly diverging frustrum of a cone shaped, deflec­tor core (1) of wear resistant ceramic, a nozzle rim (8) of wear resistant ceramic encircling the core and coextensive with a downstream portion thereof to form a mixing zone (16) therewith for receiving liquid-to-be-­atomized therein from an unobstructed passage (56) and atomizing fluid directing the liquid-to-be-atomized away from the core. The mixing zone leads to a nozzle orifice outlet (18). The core is mounted in a core holder (20) and is adjustable by a screw thread, in close proximity to the mixing zone, to adjust the width (W) of the mixing zone, and the liquid-to-be-atomized (e.g. a coal slurry fuel) and the atomizing fluid (e.g. air) are fed along coaxial tubes (72,68) which are slidably mounted by glands (106) to accommodate differential expansions. With this combination it is possible to set the width of the gap between the deflector core and the nozzle rim even before the operating temperature is reached, because negligible changes in this width will occur due to differential expansions between the nozzle components. Furthermore, accommodating different­ial thermal expansions by the slidable glands avoids any damage occurring to the ceramic parts due to differential thermal expansion.

Abstract: A completely digital robot control operates at a predetermined sampling rate. The robot arm has a plurality of joints with each driven by an electric brushless or brush-type DC motor which is in turn supplied with drive current by a power amplifier bridge circuit having power switches connected therein to supply motor winding current in the forward or reverse direction. 
     Incremental or absolute encoders and tachometers provide for generating digital position and velocity feedback signals generated synchronously with the sampling rate. Digital motor current feedback signals are also generated synchronously with the sampling rate. 
     Paired position/velocity microprocessors generate torque commands for each of the robot axes at the sampling rate in response to the position commands and the position and velocity feedback signals. Paired torque microproces­sors generate motor voltage commands for each of the robot axes at the sampling rate in response to the torque com­mands and the current feedback signals. 
     Pulse width modulators generate digital motor control signals for each of the robot axes at the sampling rate in response to the voltage commands. The digital control signals for each axis are coupled to control terminals of the corresponding power switches to control on/off switch time and satisfy the motor voltage commands and thereby satisfy the position commands.
