Title: Program-Control Electric Switches
IPC: H01H43/10
Filed: 1968-09-27
Abstract: 1,180,353. Time switches. LANDIS & GYR A.G. 27 Sept., 1968 [3 Oct., 1967], No. 46120/68. Heading H1N. A programme-control disc 16, actuating contacts, not shown, is stepped by a pawl 12 carried on one arm 9 of a bell-crank lever 6 whose other arm carries a roller 10 following a cam 5 driven by a synchronous motor 1 via gears 3, 4. A spring 13 acts on pawl 12 substantially in the direction of movement of teeth 15 engaged by the pawl, and also serves to bias the roller 10 against cam 5. The arm of the bellcrank lever 6 which carries roller 10 is split into two parts 7 and 8, as shown, the part 8 being rigid with arm 9 and the part 7 being adjustable by means of a clamping screw 11. The pitch of teeth 15 may vary to provide slower rotation of disc 16 in the intervals between contact operation. Switching steps of different duration may be obtained by selecting different gear ratios.

Title: Improvements in or relating to the production of phosphoric acid
Inventor: BROWN MARTIN GRANGER
IPC: C01B25/225
Filed: 1963-11-22
Abstract: Phosphoric acid, gypsum, and sodium or potassium fluorosilicate are produced by reacting ground phosphate rock with an aqueous solution of H2SO4 in presence of a sufficient quantity of silica or a source of silica, which is able to react with the fluorine in the phosphate rock and convert substantially the whole of said fluorine into fluosilicate ions, filtering of the pptd. gypsum and precipitating sodium or potassium fluorosilicate by the addition of an aqueous solution containing sodium or potassium ions to the filtrate and filtering off the ppt.  The quantity of H2SO4 used is 2.3 to 2.8 parts by weight of 100% acid per part of P2O5 in the raw rock.  The source of silica is preferably water soluble being sodium or potassium silicate, but it may be finely divided kieselguhr or clay. The aqueous solution of H2SO4 added in the opening-up stage may contain (NH4)2SO4. If desired the aqueous solution containing the Na or K ions may be added at the opening-up stage in quantities such that after reaction and removal of the gypsum, a saturated solution of Na or K2SiF6 is produced.  The quantity of Na or K ions added, calculated as Na2O equivalent is preferably less than 1% by weight of the original rock.

Abstract: 1401465 Delivering sheets ING C OLIVETTI & C SpA 9 Oct 1972 [8 Oct 1971 18 July 1972] 46498/72 Heading B8R Sheets which are copies of one page of a multipage document are delivered from a copying-machine 12 to the input region 16 of a collator 10, one sheet being deposited into each of a plurality of bins 18 mounted one above the other on a vertically movable carriage 26, and any additional sheets being carried by an overflow conveyer 22 also mounted on the carriage 22 to an output region 23 and thence either into a tray 24 or into a further similar collator 10. The carriage 26 is initially in an uppermost position where previously deposited sheets can be removed from the bins and wherein the lowermost bin 18L is aligned with the input path. The carriage is lowered by a reversible electric motor 34 at a variable speed, the speed being reduced as a bin passes through receiving position and increased at other times, e.g. by means of a pair of elliptical gears. If all the copies are delivered before all the bins have been used or as the last bin 18H is used, the carriage is moved at a higher speed back to its upper position. Otherwise, the carriage remains in its lowermost position, in which a gear 116 connected to the conveyer 22 is in engagement with a constantly driven gear 118 so that further copies are carried by the conveyer to the region 23. The conveyer comprises a plurality of perforated belts running over a perforated plate defining the upper surface of a suction chamber 128, which is connected to a suction source only when the carriage is in its lowermost position, the source being a blower which is driven only at that time. Thereafter, the carriage is raised ready to receive the copies of the next page so that finally each used bin contains a stack comprising one copy of each page. A photo-electric detector 140, 142 associated with a solenoid which acts to connect the motor to the lowering mechanism ensures that the bins move in synchronism with the arrival of the sheets. The detector may act as a counter to compare the number of sheets with a pre-set indication of the number of copies being made, so that a comparator initiates resetting when the run is complete.

The control flow path leads from the inlet port via passage 40, to an electromagnetically controlled variable orifice 44 and passage 42 to the chamber 18, and via passage 46, a fixed orifice 50 and passage 52, thereof a bore 28 and passage 36 in the closure member to the exhaust port. The orifice 50 is in series with a compensating valve 48 which maintains a constant flow rate through the orifice. A stabilizing piston 62 depending on the pressure in the chamber 18 acts to close the flapper 54 on to the orifice 44. A passageway 38 in parallel with the orifice 44 is provided in the closure member. The spacing of the flapper 54 relative to the orifice 44 is controlled through a solenoid by a variable resistor 58. For a given pressure in the chamber 18, any increase in pressure at the inlet above the set amount lifts the closure member to open the valve.

Title: Improvements in or relating to the Measurement of Dispersion of Light
Inventor: DYSON JAMES

Abstract: 1,182,633. Measuring chromatic dispersion photo-electrically. NATIONAL RESEARCH DEVELOPMENT CORP. Oct. 4, 1968 [Oct. 16, 1967], No.47133/67. Heading G1A. The chromatic dispersion of a light beam is measured by modulating the beam by means of a cyclically moving element, whereby the phases of the modulation for light of two different wavelengths will differ by an amount dependent upon the magnitude of the dispersion and comparing the phase of two signals respectively representing the modulation for light of said wavelengths. Light from a distant source is focused by a lens 2 or Cassegrainian telescope on to a rotating disc 3 having alternate transparent and opaque bars 8. Owing to atmospheric dispersion, displaced red and blue images 7, 6 are formed and light therefrom is directed by a dichroic mirror 9 to photo-multipliers 10, 11. Phase comparison of the photo-multiplier outputs gives an indication of the dispersion on meter 8. A glass plate 14 may be adjusted manually or automatically to reduce the meter reading to zero, the dispersion being indicated on a scale 16. Since the dispersion is proportional to the displacement of the image of the distant object by the atmosphere, dispersion may be taken as a measure of displacement and if plate 14 is suitably chosen adjustment to eliminate dispersion will also compensate for displacement. The invention may be used in a theodolite.

The segments of the detector are coupled together in diametrically opposed pairs Dd, Ee etc. isolated from the other pairs and from a central detector. Each pair can be sampled successively using a multiplex switch or all pairs may be sampled concurrently with the most aligned pair being selected by appropriate circuitry. The data (Fig. 2, not shown) is preceded by a narrow alignment bar which is as wide as the widest part of each detector pair. When the detector, which may be hand held, is passed over the record the outputs of the pairs are sampled and the one with the lowest output, i.e. the one with the best alignment with the alignment bar is selected. During readout adjacent pairs are sampled in case relative rotation of the detector changes the most aligned pair. Circuits for selecting the most aligned pair by comparing the levels of reflected illumination or the slope of the transition occurring between dark and light bars are described.
