Title: Wet process phosphoric acid processing appts. - with use of pipes smoothed by electropolishing to minimise deposition of calcium sulphate and alkali fluosilicate encrustations
Inventor: AHLGRIM MICHAEL
IPC: C01B25/222
Filed: 1980-10-17
Abstract: Use of pipes and appts. parts the surface of which coming into contact with solns. contg. phosphorus cpds. are smoothed by electropolishing in the prodn. and processing of phosphoric acid obtd. by wet digestion rock phosphate with mineral acid is new. Electropolishing of the surfaces coming into contact with the soln. contg. phosphorus cpds. prevents the formation of hard and persistent glassy deposits which could otherwise lead to blockages of pipework, as well as the formation of scale-like deposits in the interior of high-speed coolers. Such deposits of gypsum and alkali fluosilicate are not prevented by polymer (e.g. PTFE) coating, but electropolishing limits deposits to a thin coating which can easily be removed by rinsing with NaOH solution or phosphoric acid.

Title: Gauge for a measurement object configured in a spatially complicated fashion, in particular for a vehicle body
Inventor: TODOROVIC VLADAN
IPC: G01B7/287
Filed: 1981-05-30
Abstract: The invention relates to a gauge for a measurement object configured in a spatially complicated fashion, in particular for a vehicle body. Provided on the measuring frame, which accommodates the body in a defined way, are a plurality of probe devices each of which is assigned with its prod to a measuring point. The prodder can be moved up fluidically into a measuring position on the measurement object, or withdrawn into a waiting position. In order to reduce the overall size and the sensitivity to malfunctions due to dirt and collision, a compact design is proposed for the probe devices in which the sleeve is mounted robustly but precisely in a housing, and in which the displacement sensor and the fluidic working element for the movement drive of the sleeve are also integrated. The prod is mounted in a freely movable, but axially fixed fashion on the free end of the sleeve inside a plane perpendicular to the axis, and coupled to a two-dimensional displacement sensor in order also to detect the two space coordinates situated transversely to the axis of the sleeve. Not only does the compact design make the probe devices less sensitive to malfunctions, it also permits them to be arranged in a closer mutual spacing, and to be arranged on the outrigger (boom) of a measuring robot, which can approach measuring points at locations which are difficult to access and constricted.

Title: Lifting appliance for moving loads manually
Inventor: DOLINSEK HANS
IPC: B66C23/00
Filed: 1982-02-12
Abstract: The lifting appliance has a jib (16) which is mounted on a support (12) in such a way as to be pivotable at least about a horizontal axis (17). To produce a force moment which balances the load moment at a certain inclination of the jib (16), a working cylinder (28) is provided whose working pressure is kept constant by a control unit (37) at all inclinations of the jib (16). This working cylinder (28) is connected in an articulated manner to the jib (16) and the support (12) at such well-chosen locations (31, 32) that the difference between load moment and force moment, which difference is caused during the pivoting of the jib, can be coped with manually by one operator. In order to adapt the working pressure in the working cylinder (28) to the respective load, the jib (16) is connected to the load suspension means (23) in such a way as to be movable upwards relative to the load suspension means (23) against a restoring force. This relative movement controls the control unit for setting the working pressure, adapted to the load, in the working cylinder (28). <IMAGE>
