Abstract: A protective circuit for reducing subsynchronous natural resonant frequency signals in a multiphase power supply system includes a damping resistor connected in series with each phase winding of the system. A resonant circuit tuned to the rated line frequency of the system is connected in parallel with each resistor so that signals having frequencies other than the rated line frequency will be damped by the resistors. An inductor can also be placed in parallel with each resistor to maximize the damping effect of each resistor at predetermined subsynchronous frequencies.

Abstract: A power-assisted steering gear has reaction means to provide a "road feel" at the steering wheel. The gear includes a steering spindle comprising a first part 1 and a second part 2. The first part is formed with a rotary valve 3 and the second part 2, which is constructed as a steering worm, is formed with a control bush 5 cooperating with the valve 3 which is connected to the steering worm via a torsion rod 6. The steering worm is operatively connected by way of recirculating balls 14 to a power piston 13 which is axially slidable in a gear casing 12 and meshes with a steering sector 16. The torsion rod 6 is surrounded by a hollow reaction piston 20 which is supported on the two ends 23, 24 of the torsion rod 6. The adjacent ends of the reaction piston 20 and the first steering spindle part 1 are formed with complementary V-shaped recesses 21,22 which upon assembly of the two elements 1 and 20 form, in conjunction with the peripheral surface of the end 23 of rod 6, a peripheral zig-zag channel which serves to guide a row of balls 25. The channel with the balls 25 constitutes centring means for the rotary valve 3, 5. At its end remote from the centring means the reaction piston 20 forms a chamber 30 which accommodates a centring spring 31 and which is connected to a working pressure duct 34, 35. <IMAGE>

IPC: G01N21/88
Filed: 1983-03-22
Abstract: An optical inspection system is disclosed which determines surface and other features of objects by illuminating them with a light beam having substantially uniform light intensity in space and time. The light beam is derived from a light source whose light intensity may vary in space and time. The surface features of each object are inspected by detecting light reflected from the object through a lens system which focuses the reflected light on an array of photosensitive elements. The output signals provided by the array may be used to provide a measure indicative of the conformance of the inspected surface to predetermined criteria. The inspection system is further capable of determining other features of the inspected object, such as the height of the object, by illuminating the object with a second light beam derived from a second light surface. A portion of the second light beam is eclipsed by the object and the non-eclipsed portions are directed to a second array of photosensitive elements to provide signals indicative of the desired dimension.

Date Sep. 26, 1985.According to the invention a piezoelectric crystal, e.g. a quartz crystal, coated with a metal or another suitable material is exposed to the action of a corrosive liquid, preferably by being immersed therein. The mass change on the crystal surface, caused by the corrosion, and the resulting change in the natural oscillation frequency of the crystal is determined and constitutes a measure of the corrosivity of the liquid. The natural oscillation frequency of the crystal can in this way also be measured in situ in the liquid, in which way the dynamic course of the corrosion reaction can be followed continuously. According to a special embodiment of the invention the sensitivity during the measurement can be increased, if the crystal is pretreated by being activated with a sulphide solution.
