Title: Improvements in or relating to Power-Driven Polishing and Like Machines.
Inventor: DAVIES LESLIE ALFRED
IPC: A47L11/40
Filed: 1967-10-18
Abstract: 1,180,040. Floor polishing machines. DOWDING & PLUMMER Ltd. 22 Oct., 1968 [18 Oct., 1967], No. 47419/67. Heading A4F. In a polishing or like machine having a control handle 17 extending upwardly from a unit 10 having a rotary head 11 with a generally flat polishing face, a stay 22 pivotally connected to the handle 17 and the unit includes two resiliently connected rigid members 25, 26 and a clamping screw 30 for preventing relative movement between the members 25, 26. The resilient connection between the members 25, 26 comprises rubber bushes 34, 35 mounted in the member 26 above and below a rigid insert 31 and between plates 36, 37 secured to a rod 33 extending into the member 25 and securable therein by a clamping screw 38. When the clamping screw 30 is tightened the handle 17 cannot pivot about its connection 18 with the unit 10, and the machine requires more skilful operation than when the clamping screw 30 is released. In the latter case if the clamping screw 38 is tightened the handle 17 can be tilted relatively to the unit 10 within limits determined by the compression of the bushings 36, 37. Release of both clamping screws 30, 38, permits the mean angle of tilt of the handle 17 to be adjusted.

Title: Spool holding device
IPC: D01H1/18
Filed: 1970-10-06
Abstract: 1280935 Spool holding device MURATA KIKAI KK and DAIWA BOSEKI KK 6 Oct 1970 [11 Oct 1969] 47553/70 Heading D1J The spool holder A has a ring 2 of soft deformable material that is caused to expand automatically and grip the spool 23 internally. When the spool 23 is raised onto the holder part A when below it lifts the end of a lever 9 in a clockwise direction against the resilient force of a spring 10. This movement of the lever 9 disengages its claw end 8 from a latch pin 14 to permit upward movement of a central shaft 13, and therewith of a head body 3, under the influence of spring 17. The ring 2 is thus compressed between the main body 1 and the head body 3 to cause it to bulge outwardly. When it is desired to release the bobbin the upper end 16 of the central shaft 13 is manually depressed against the force of the spring 17 to cause the latch pin 14 to be moved downwardly beyond the claw 8 and so permit the claw 8 to hold the shaft 13 in its depressed setting. The resultant downward displacent of the head body 3 from the main body 1 releases the compression on the ring 2.

Title: Method and Apparatus for Scanning an Edge of a Body
IPC: G07C3/14
Filed: 1966-11-03
Abstract: 1,171,134. Photo-electric contour checking. EMHART ZURICH S.A. Nov.3, 1966 [Nov. 5, 1965], No.49271/66. Heading G1A. The geometry of an edge 6 of a body 4 and the height of the edge above a reference plane 1, are investigated using photo-electric scanning apparatus to obtain information as to the plane parallelism of the body, the presence of crevices within it &c., so that a body not within prescribed tolerances may be rejected. In the scanning of a body, pairs of points, A, A', B, B' &c., on the edge and which would be symmetrically disposed about an axis of symmetry of the edge if the body was correctly shaped, are investigated, and their positions, relative to the reference plane, compared. In the described embodiment, the bodies are cylindrical and are conveyed on a belt 1, which represents the reference plane, through the photoelectric testing station. Light sources 10, 10', each provided with a lamp 12, a condenser 14 and a mask 16, project slit-shaped beams of light on to the edge 6 from either side of the body. The light not obstructed by the body is focused by lenses 20, 20' into images 24, 24'. Light guides, Fig. 2 (not shown), each composed of a bundle of light conducting fibres arranged in a row, (or mirror or prism systems) conduct these images to the photoelectric detectors. Interposed between the ends of the light guides and the detectors is a rotating disc having two radial slits arranged to cross in front of the ends of the light guides in synchronism (although an alternative one-slit disc is also described). The outputs of the detectors are thus two pulses, beginning at the same instant but ending at times dependent on the height of the edge 6 above the reference plane 1 at the two points A, A' considered. By the time the scanning disc revolves one revolution, further points B, B' will be in line with the beam. Thus a series of pairs of points along the edge may be investigated, the number of pairs depending on the speed of revolution of the scanning disc. A profile of the edge may be built up given by the output of the photo-detectors, Figs. 5-7 (not shown), and the height of the face 6 from the reference plane determined. The circuit, Fig. 8 (not shown), for analysis of the detector pulse output includes gating circuits (54, 58) and clocks or counters (66, 72) by which the permissable tolerances may be set to check symmetry and elevational deviations of the edge. The movement of the body 4 need not be translational but can be rotational for bodies having symmetry about a single axis. In the case where only translational movement is possible, it is preferable to reorientate the body and do a further scan to avoid certain types of error and cover parts of the edge to which the scanning system was "blind" during the first scan.

Title: Extraction of manganese from ores as manganous sulphate
Inventor: SANDOR FEKETE ALBERT HORVATH J
IPC: C22B47/00
Filed: 1963-12-31
Abstract: Materials containing carbonate and oxide manganese ores, dressing middle products and/or dressing barrens are wet-ground and the resulting slurry is reacted with oxygen containing waste gases or an air mixture both containing 0.2-5% by volume of sulphur dioxide in equipment ensuring contact over a large surface area, e.g. a flooding foam column, to produce manganous sulphate solutions.  The manganese content of the manganous sulphate solutions may be recovered as manganic oxides by adding calcium carbonate (preferably ground limestone) to the solution, separating the precipitated iron and phosphorus content, adding calcium hydroxide solution and then separating calcium sulphate from the manganous hydroxide (if formed), e.g. by counter-current sedimentation, oxidizing the manganous hydroxide to manganic hydroxide, preferably by bubbling air through the solution, and then separating, drying and/or agglomerating the product obtained. Under certain conditions, e.g. manganous sulphate concentration not exceeding 5 g./l. and calcium hydroxide solution added until pH is 7 to 7.2, no precipitation of calcium sulphate occurs. Alternatively, impurities are removed and the resulting solution is electrolysed giving manganese metal. Further, the dissolved contaminants may be removed from the manganous sulphate solution with the aid of calcium carbonate, whereafter the manganese content is recovered either by crystallization as manganous sulphate, or, where a compound other than the sulphate is desired, by adding a solution of an inorganic salt (e.g. sodium bicarbonate) or an inorganic base (e.g. calcium hydroxide) and recovering the manganese in the form of a manganous salt other than the sulphate or manganous hydroxide respectively.
