Patent GB-1025960-A (GB)
Title: Coated titanium dioxide pigments
Inventor: STALKER IAN NICOL
IPC: C09C1/36
Filed: 1963-07-10
Abstract: Pigmentary TiO2 particles are coated with an aminated polysaccharide, which may be added as a particulate solid during dry or wet milling of MeTiO2 or suspended in water before being added to dry TiO2, which is then milled. Alternatively the dry polysaccharide is added to an aqueous TiO2 dispersion, followed by drying and/or milling.  The TiO2 may retain at least 0.25%, based on TiO2, of the polysaccharide, which has at least one amine group per molecule and a molecular weight above, say, 750.  Specified polysaccharides are aminated galacto-mannans, starches and celluloses. The TiO2 may be rutile or anatase.  Rutile pigments coated with a hydrous metal or metalloid oxide and recalcined may be used.ALSO:Cellulose fibre sheets, normally paper sheets, contain TiO2 particles coated with an aminated polysaccharide.  The treated pigment is added e.g. as a solid at the beater stage, or as a slurry (in the presence of a surface active agent if desired) at the beating stage or any intermediate stage before the sheets are formed.  When an aluminium salt is added during the manufacture of paper the treated TiO2 may be added before the salt or along with it, or in the case of TiO2 treated with an aminated starch, after the addition of the salt.  Rutile TiO2, which has been previously calcined, coated with a hydrous metal or metalloid oxide and recalcined prior to treatment with a polysaccharide, may be incorporated in paper laminates. Specified polysaccharides are aminated galacto-mannans, starches and cellulose.

In a third embodiment, Figs. 10 and 11 (not shown), a single aperture is controlled by two pivoted trapezoidal cover plates, and the discharge chamber has a discharge duct at each of its ends. In a fourth embodiment, Fig. 12 (not shown), similar to that in Figs. 10 and 11, each cover plate carries at its end remote from its pivot a pivotally mounted auxiliary cover plate which can be separately adjusted. In a fifth embodiment, Figs. 13 and 14 (not shown), the partition comprises the upper run of an endless metal or rubber strip which has an aperture in it whereby by 'moving the strip the position of the aperture is altered. The strip extends over pairs of rollers one of which is drivable through gearing by a hand crank. The aperture may be circular, elliptical, rectangular or trapezoidal, or be of irregular shape, and the bottom run of the strip is perforated. In a sixth embodiment, Figs. 15 and 16, a single aperture has at one of its longitudinal sides an adjustably mounted, rectangular, rigid cover plate, and at its other longitudinal side a thin cover diaphragm of rubber, plastics or metal, e.g. steel, and which is flexibly adjustable in its own plane by push rods, its flexibility being enhanced by deep slits being cut in its edge remote from the aperture. In a seventh embodiment, Figs. 17 and 18 (not shown), a single aperture is controlled only by a thin flexible cover diaphragm similar to that in Figs. 15 and 16 although control; may be by two such diaphragms. The invention may be applied to a cylinder mould machine.

Abstract: 1,134,418. Separating sheets from piles. VEREINIGTE OSTERREICHISCHE EISEN UND STAHLWERKE A.G. 21 June, 1966 [24 June, 1965], No. 27721/66. Heading B6B. [Also in Division B8] Apparatus for separating steel or iron sheets B from a stack 1 comprises a raisable suction head 5 to initially engage and raise the sheets from the stack and a magnetic head 3 pivotable between one end position to engage the lifted sheet and another end position to deliver the sheet to a conveyer 4. A series of rotatable magnetic discs 7 mounted on a shaft adjacent the vacuum head 5 have non-magnetic arms 8 to engage the rear edge of the lifted sheet and urge said sheet into contact with the magnetic head 3. Stripper arms 19 are positioned to release the sheets from the rotating magnetic discs 7. The separating apparatus is mounted on a carriage 2 provided with wheels 12 to engage rails 14 mounted on a transport car 16. The transport car 16 has wheels 22 to engage rails 23 to move transverse of the rails 14 and align said rails 14 with stationary rails 15 whereby the carriage 2 may be removed from the unloaded transport car 16 to enable a loaded transport car 16a to be aligned with rails 15. The carriage 2 is then moved on to the transport car 1 6a to commence unloading. Each transport car mounts a platform 29 on which the sheets are stacked and which is controlled by photo-electric means to maintain the uppermost sheet on a level with the conveyer 4. The conveyer 4 comprises driven magnetic discs 4a feeding a roller conveyer 18. The magnetic discs are provided with stripper arms 4b operable by a pneumatic jack 4c and controlled by a selenium cell 10 disposed before the discs 4a to register the trailing edge of a sheet. The speed of the driven discs which regulates the spacing between sheets on the conveyer 18 is controlled by comparing pulses from selenium cells 9, 10 respectively registering the leading and trailing edges of the sheets and the gap between the sheets.

Title: Improvements in or relating to data transmission systems
IPC: H03K3/2893
Filed: 1966-06-21
Abstract: 1,201,023. Electronic selective signalling systems. A. J. BAGGOTT. 19 Sept., 1967 [21 June, 1966], No. 27740/66. Heading G4H. In a system for transmitting data a short duration pulse is applied to a pilot line at a predetermined phase relationship to an alternating signal, and at the distant point there is gating means arranged, when open, to receive the short duration pulse, and means responsive to the phase of the alternating signal to open the gating means at the correct instant. At the transmitter Fig. 3 the three phases R, Y, B of the supply are applied to a timed pulse generator 23. The Red phase is connected to a clock pulse generator 25, the output being applied to a three-stage counter. The outputs select the three phases in turn. There are six timed pulses in each phase and these are selected in turn by the stages of counter 27, driven from the last stage of counter 26. The outputs of the counters 26 and 27 are applied to generator 23 to select the controlling phase and one of six phaseshift circuits. The timed pulses are applied to one of 4 leads 30, selected in turn by counter 28. Each lead is connected to 18 receiving units, each of which may be as shown in Fig. 4. A watt-meter at each remote station is arranged to close a switch MS when each Kilowatt-hour has been consumed. This sets a flip-flop 47, 48. The mains voltage is applied to a transformer 31 and a phaseshift network 38, 39 sets a Schmitt trigger 40 the output of which is differentiated by capacitor to give the timed pulse, the timing of which is characteristic of the station. If the trigger 47, 48 is set diode 49 is cut off and the incoming timed pulse cuts off diode for a short period 46 so that if the pulse from capacitor 50 comes within the same period a signal is applied to the base of transistor 52, passing an output via diode 54 to the return line 44. At the transmitting station the returning signals are distributed to corresponding ones of 72 leads by gates enabled by the outputs of counters 26, 27, 28, each lead being connected to a counter counting the number of times the corresponding switch MS has been closed.
