Title: Determining the diameter or cross section of threads
IPC: G01B11/10
Filed: 1980-10-08
Abstract: To determine its diameter or cross-section, a thread 11 is caused to travel between a light source 10 and a receiving device 13. The illumination of the device 13 is measured by the shadow (as shown) or reflection of the thread 11. The device 13 has a series of individual photo sensors which are scanned to produce a representation of the diameter or cross-sectional image in the form of a pulse sequence, avoiding the need for an analog digital converter. For non-circular cross- sections a two-beam system is used (Fig. 4 not shown). By use of suitable pulse thresholds the roughness of the surface is measured. Also the thread position or the presence of protruding bristles may be detected. <IMAGE>

Patent GB-2076101-A (GB)
Title: A device for signalling the clutch wear in servoclutches particularly for motor vehicles
IPC: F16D25/12
Filed: 1981-05-15
Abstract: A device for sensing and signalling the wear in servoclutches has a cap 20 secured to the upper end of the tube 8 in which the stem 9 operatively connected with the clutch is slidably mounted. The end of the stem 9 is perforated to house a bush 28 with a flange 27 which is retained in engagement relationship by a spring 30 against the edge of said tube 8. The lower end of a perforated pin 24 integral with the cap 20 and provided with radial holes 25 and 26 of different section is slidable in the hole of bush 28. As the clutch wear increases, the bush 28 is lifted so that its upper edge gradually closes the larger hole 26, limiting or choking the passage of oil from the connector 22 to the chamber G, thus signalling the clutch wear to the user through the increased resistance to clutch pedal operation by which the oil is pumped to the connector 22. The clutch is actuated pneumatically when a valve is opened by oil passing from chamber G to that valve through a hole 10. <IMAGE>

Patent GB-2081419-A (GB)
Title: Hydraulic shock absorber
IPC: B60G17/08
Filed: 1981-07-23
Abstract: A hydraulic shock absorber for a vehicle body suspension comprises a piston 2 working in a main cylinder 1 filled with oil and enclosed within a co-axial auxilliary cylinder 3 and an outer tube 4. The main cylinder 1 has ports 16 and 17 respectively above and below the position taken up by the piston 2 when the vehicle is stationary, as shown in the drawing. When the stroke of oscillation of the piston is less than the distance between the ports 16 add 17 oil flows through these ports and only a slight shock absorbing effect is obtained. For larger strokes of the piston resulting from rough roads, flow through the ports 16 and 17 is interrupted and a stronger shock absorbing effect is obtained. <IMAGE>

Title: Reducing Iron Content of Raw Materials
IPC: C01F7/56
Filed: 1981-08-26
Abstract: The iron content of iron-, silicon- and aluminium-containing raw materials e.g. bauxites, clay minerals, colliery rocks, and red minds, is reduced by passing an aqueous hydrochloric acid solution the concentration of which exceeds 100 g./l, through one or more beds of the unground but preferably prebroken and sized raw material, at a temperature below 90 DEG C, preferably at room temperature, optionally in the presence of a flocculating agent. The ferric chloride produced is separated and subjected to pyrolytic decomposition to produce ferric oxide. The bed residue of reduced iron content can be utilized in the Bayer process for producing alum earth, as a starting substance of ceramic industry or, after treatment with sulfuric acid, dissolution in hydrochloric acid or water, elimination of silica, and pyrolytic decomposition of the aluminium sulfate obtained, as an alumina concentrate.
