Abstract: 927,678. Tractor power-lift linkage mechanisms. ROBERT BOSCH G.m.b.H. June 8, 1961 [June 9, 1960], No. 20656/61. Class 79(1) A tractor hydraulic control apparatus comprises a slide valve 7 automatically adjustable in the cylinder 5 under the action of an implement supported by the tractor whereby either pressure fluid flows from a pump 1 to an implement working ram 20 via conduit 3, grooves 4 and 9, chamber 13 and conduits 17, 17<SP>1</SP> which include a non-return valve 18, or the pressure fluid is guided via conduit 3, grooves 4 and 8 to chamber 12 from where it is returned to reservoir 2 via return conduit 15. An auxiliary control device 32 is connected, in the " lowering " position S of the slide valve 7, to the pressure supply via conduits 26 and 31 and grooves 27, 28 so that a spring biased piston 35 is forced into the position shown in Fig. 1 whereby the chamber 13 is connected via conduit 40, and bore 42 with the return conduit 15. In this position the pressure conduit 17<SP>1</SP> is connected to the return conduit via conduit 21 and groove 23 and bore 24. in the slide valve to release pressure in the ram. In the " raising " position H of the slide valve, the pressure supply is cut off from the piston 35 so that its spring moves it to cut off the chamber 13 from the return conduit so that pressure fluid is supplied to the ram 20. In an embodiment a pressure relief valve is incorporated between conduits 3 and 15 and a blocking valve is inserted in the conduit 21 which is then connected directly to the conduit 15. The blocking valve is opened, in the " lowering " position, by pressure from the conduit 26. A compact arrangement in which all the control elements are located in one block, the auxiliary control device being located in one end of the slide valve, is also described.

Abstract: 334,992. Maina, J., and Davidson's Patents, Ltd. July 6, 1929. Clutches, ratchet ; differential gearing, facilitating changing speed. - In free-wheel friction clutches for motor vehicles &c., of the kind in which the axial reaction of helical gear-wheels effects automatic engagement and disengagement of the friction members, as described in Specification 308,451, an internally-toothed casing b on a driving or driven shaft a engages planet-pinions # on a carrier c slidably mounted on a driven or driving shaft d, the pinions # meshing with a sun-wheel g loose on an extension h of the shaft a, so that axial thrust on the planet-pinions is balanced. A disc i, slidable on the hub n of the wheel g, coacts with a flange, j on the casing b and a loose disc k acted on by cam-levers m, which engage a groove in the hub n and are shaped to press the parts k, i, j together when the wheel g is thrust in either direction due to torque and its frictional resistance. The carrier c can, however, be moved inwards by control-means o to prevent movement of the wheel g in one direction and so allow over running. The Provisional Specification describes a form in which the disc i is rigid with the hub and is carried into contact with either of two surfaces on the casing, the levers m being omitted.

Title: Improvements in or relating to the production of calcium sulphate ª‡-hemihydrate crystals
IPC: C04B11/024
Filed: 1963-05-24
Abstract: a -CaSO4. 1/2 H2O crystals are produced by heating an aqueous suspension of synthetic CaSO4.2H2O (e.g. gypsum obtained in the wet recovery of H3PO4 from phosphate rock and H2SO4) of pH from 1-5, containing a crystallization promoter (as defined), at 105-140 DEG C. to form seed crystals of a -CaSO4. 1/2 H2O, then adding an aqueous suspension of synthetic CaSO4.2H2O continuously or intermittently while maintaining a pH of 1-5 and a temperature of 105-140 DEG  C. to form the required crystals.  The seed formation step may be carried out under pressure or in the presence of a dissolved salt, e.g. 29% CaCl2 and 1% KCl, of such concentration that the b.pt. is above 105 DEG  C., the suspension then being heated at atmospheric pressure, below and close to its b.pt.  The dihydrate added in the second step may have a pH of 1-5 and contain seed crystals and/or a crystallization promoter.  pH is adjusted by adding CaO or Ca(OH)2. The crystallization promoter may be a surfactant, e.g. alkaryl sulphonates, sulphite liquor, or setting retarders, e.g. Al2(SO4)3 or dicarboxylic salts.  The product has a high compression strength, and may be formed into moulded bodies.

Abstract: 1,143,394. Coated copper sulphate. MIDLAND SILICONES Ltd. 12 May, 1966 [18 May, 1965], No. 20882/65. Heading C1A. [Also in Division A5] Finely divided copper sulphate preferably having a particle size of less than 10 mesh (British Standard) is coated with an organosilicon compound, e.g. by contacting with the vapour of the organosilicon compound or by applying the organosilicon compound in a suitable solvent, such as 40/60 petroleum ether, which is subsequently evaporated. Suitable organosilicon compounds are the hydrolysable alkoxy organosilanes, organochlorosilanes and the organopolysiloxanes derivable therefrom, and particularly the material obtained as a by-product of the direct process reaction for making chlorosilanes. If desired other materials such as catalysts for hardening or fixing the organosilicon compound on the copper sulphate may be employed. 0À01 to 5% by weight of organosilicon compound reduces the water solubility of the copper sulphate.

Title: Speed detection and control

Abstract: 1310586 Detecting speed electrically MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 1 May 1970 [8 May 1969 30 May 1969 10 June 1969] 21163/70 Heading G1N [Also in Division G3] To detect the speed of a magnetic recording medium, a recording head 9 and reading head 8 are disposed adjacent thereto at a distance P apart measured in the direction of travel. The head 9 imposes a mark 14 on the medium, as shown a magnetic tape, and when this reaches the head 8 it is read the output being applied to an amplifier 16 whose output triggers an astable multi-vibrator 11 into changing its state. The output therefrom is amplified at 13 and applied to the head 9 to cause a further mark 17 (of opposite polarity) to be made. Thus a series of equispaced marks 19, 18, 14, 17 are formed on the tape, and the frequency of the signal 24 from amplifier 16 gives a measure of the tape speed. Desirably, this frequency may be 30Hz given by 2P/V where V is the speed. The multivibrator has a natural frequency somewhat lower than 30Hz say 28Hz. To control the speed of the tape this measured signal 24 together with a 30Hz reference signal 23 are fed to a phase comparator 25, the error signal output being filtered, amplified at 26 and applied to a controller 27 to control either an A. C. synchronous motor or an eddy current brake associated with an A. C. induction motor. Fig. 4 discloses a magnetic video recording/ reproducing system utilizing the above-mentioned markirg and speed control arrangement 11, 13, 16 etc. In this system a rotating head disc 28 carrying two heads 29, 30 is driven to rotate at 30Hz. The actual frequency of rotation, as determined by a magnet 32 and detector 33, is compared with a 30Hz reference signal 23' in a phase comparator 25' and the error signal used to control motor 2'. In the recording process switches S1, S2, S3, S4, are set to the R position, and the components 7, 11, 13, 16, 25, 26, 27 operate as described above. In addition a control head 34 energized from the 30Hz reference source 23 provides control marks 36, these over-writing the marks from head assembly 7. For playback the switches are set to the P position, comparator 25 is fed with the reproduced signal from marks 36 and with the detected speed of the disc 28 in order to control motor 2. Modification of this arrangement disclose (a) two separate mark tracks Fig. 5 (not shown) and (b) the elimination of the control head 34, Fig. 6 (not shown). A further arrangement Fig.7 (not shown) utilizes a rotating magnetic disc, and the two magnetic heads are so disposed that spaces between adjacent marks are all equal. Rotational speed is controlled in accordance with a reference signal as described above. This embodiment is particularly applied to a magnetic disc type magnetic video reproducer apparatus.
