Patent GB-1474009-A (GB)
Title: Provisions of flame retardant properties for textile materials
IPC: D06M11/47
Filed: 1975-04-04
Abstract: 1474009 Flame-proofing textiles COTTON INC 4 April 1975 [15 April 1974] 13964/75 Heading D1P Cellulosic or protein fibres are flame-proofed by treatment with (a) a phosphorus containing flame proofing agent having a cation exchange capacity, (b) antimony oxide and (c) a halogenated polymer so that the fabric contains 0.5 to 10% by weight of (a)+(b)+(c), as phosphorous plus antimony plus halogen; and (d) a solution of titanyl sulphate. Preferably the atomic ratio of Ti to P in the material is 0.5:1 to 5:1, most preferably 1:1. The phosphorus compound may be phosphoric acid, alone or combined with urea, cyanamide or dicyanamide, mono or diammonium phosphate and chloromethylphosphonic acid. The presence of titanyl sulphate prevents the exchange of acidic phosphate hydrogen for metal ions on washing the fabric and thus maintains the flame-proofing action of the phosphate. The halogen-containing polymer may be polyvinyl chloride or polyvinylidene chloride. The fibres may be cotton, linen, regenerated cellulose e.g. viscose rayon, partly etherified or esterified cellulose, paper, wood, wool, silk, casein or blends thereof, as fibres, yarns, woven, non-woven or knitted fabrics. In example 1 a cotton twill is padded with an aqueous bath of 12% urea, 6% (NH 4 ) 2  HPO 4 , 5.6% P.V.C. and 4% Sb 2 O 3  to give an 80% wet pick-up. The fabric is dried at 250F for 5 minutes, cured at 350F for 2 minutes, washed, soaked for 5 minutes in a solution containing 30% titanyl sulphate, padded out, neutralised in 0.6% soda ash, rinsed and dried. In example 10A the Sb 2 O 3  and P.V.C. are applied after the titanyl sulphate whilst in example 10B they are applied between the phosphate and the titanyl sulphate.

Title: Improvements in radio direction-finding equipments
IPC: G01S1/02
Filed: 1936-05-21
Abstract: 474,690. Directive wireless signalling. PLESSEY CO., Ltd., and BAILEY, C. E. G. May 21, 1936, No. 14428. [Class 40 (v)] In direction-finding, in order to prevent signals reflected by the ionosphere from obscuring the directional indication given by the direct wave, a cathode-ray indicator is used, and the receiving circuits are inhibited for a short period after the arrival of each direct impulse so as to remove or diminish the brightness of the trace formed on the fluorescent screen. As shown, a tuned circuit Z in the output circuit of the last H.F. stage V1 is paralleled by a diode V2, the load circuit of which includes a rectifier V3 and resistance R1 shunted by a condenser C2. A connection G applies the built-up voltage across C2 to the control-grid of a cathode-ray tube (not shown), the effect being to allow the direct impulse to form a trace, which is then deleted or diminished by the applied voltage before the reflected signal comes in. A leak resistance R2 then restores the circuit to normal. The circuit shown may be duplicated across a common diode which serves to render the control independent of the strength of the received signals.

Patent GB-147467-A (GB)
Abstract: 147,467. Trinks, F. June 26, 1915, [Convention date]. Multiplying and dividing apparatus.-In machines of the pin-wheel and cam-disk type in which a rack-bar is provided to enable the cam-disks to be re-set automatically to normal position, means are provided to effect the automatic movement of this bar into and out of operative position during each rotation of the operating-crank, such means being adapted to be rendered inoperative when desired. The rack-bar c in the normal position shown in Fig. 2 has its teeth d lying beneath the spaces between the slots a through which the setting-levers b of the cam-disks project. A cam g on the shaft f of the cam-disks is adapted at the proper moment to raise a lever h, the bevelled edge of which is thereby pressed against a correspondingly shaped plate i on the rack-bar and moves the bar against the action of a spring k until the teeth d thereon lie under the first portions of the slots a. The setting-levers b are retained until they are in the zero position, whereupon the lever h is released and thus allows the rack to return to normal position, further movement to the left being prevented by a stop l. The stop l can be rocked out of engagement with the rack-bar by means of a lever m which is adapted at the same time to raise the lever h out of operative relation with respect to the cam disk g. The return movement of the lever restores the parts to position for automatic action. In those machines in which the setting levers are disengaged from the cam disks before rotating the operating-crank, the cam disks are re-set as above described, and the setting-levers b<1>, Figs. 9, 10 are restored to the zero position by means of toothed sectors p engaging with pinions o on a spindle q provided with zeroizing-means and adapted to slide longitudinally in the known manner. The rotation of the spindle q is effected by a pinion s thereon engaging a toothed sector r on the shaft f.

Abstract: 1341538 Rotary drum filter IMPROVED MACHINERY Inc 29 March 1972 [14 April 1971] 14784/72 Heading B1D An inward-flow litter drum 20 rotates clockwise in an arcuate vat 10, 14, suspension to be filtered being delivered under pressure through axial gap 48 into a converging space between the drum and an arcuate baffle 52, hinged to the vat at 56 and being resiliently urged towards the drum. In Fig. 1 the baffle is so urged by rams 66 and by the delivery of washing water under pressure through inlet 68. The water flows round the drum and into spaces 74, 76 separated by fixed baffle 72. Water from space 74 flows inwards through the filter cake on the drum, and water from space 76 flows into space 84 outside a second baffle 80, similarly constructed to baffle 52, urging baffle 80 inwards to press the washed cake. Resiliently loaded roller 98 presses the cake further, and the cake is removed from the drum by blades 108, 110 and the drum cleaned by spray 112. The baffles 52, 80 are lined with PTPE to reduce friction with the cake. The baffles could be urged inwards by springs (Figs. 6 to 9, not shown), but rams 66, 88 enable them to be withdrawn from the drum to enable incoming suspension to clear any blockage between the vat and drum. In Fig. 7 the space between baffles 52 and 80 is divided into compartments into which two different cake-washing liquids are delivered. Fig. 10 (not shown) illustrates how baffle 52 may be urged inwards by liquid delivered to a closed chamber (60f), a separate inlet (140) delivering washing liquid. Baffles 52 and 80 may have external reinforcing ribs extending from their hinged ends but stopping short of their free ends.

The connection is effected by cams 5, 6 mounted on the same shaft as the lever 2 and profiled to avoid critical periods and to give fuel economy. Curves are given showing how these profiles are ascertained. The cams operate through rollers 9, 10 and bell-crank levers. Operating levers 16, 17 connected to the propeller pitch and turbine control gear by links 18, 19 or by mechanical, hydraulic, pneumatic or electric connections which may include servomotors are mounted on the same shaft 15 as the indicators 7, 8 and are coupled to them so that direct control is effected. Return indicators 21, from one or both control gears, indicating that the controls have been effected, are mounted on the same shaft. The levers 5. 6 may be connected directly to the control gears, the indicators being then omitted. The indicators may be repeated or replaced by indicators operating in the engine room when the lever 2 is mounted on the ship's bridge, but alternatively, the device as a whole may be remotely controlled from that position. The scale 3 may be adjustable about the shaft 4 to compensate for draught. The Specification as open to inspection under Sect. 91 comprises also a Figure showing the turbine control system in detail, but this is not described: This subject-matter does not appear in the Specification as accepted.
