Patent GB-1030739-A (GB)
Title: Treatment of superphosphate
Inventor: YEOMANS PETER WILLIAM
IPC: C05B1/02
Filed: 1963-04-26
Abstract: Superphosphates having a particle size greater than 100 mesh B.S.S. and from which phosphoric acid is readily extractable is produced by adding less than 15% of urea or ammonium nitrate to raw superphosphate containing a liquid phase and heating the mixture with agitation in a rotary tube.  The urea or ammonium nitrate is employed in the smallest particle size possible. A product less than 15% of which has a particle size greater than 12 mesh B.S.S. is produced by passing the raw superphosphate through a pulveriser to remove or reduce the fraction having a particle size greater than 12 mesh or sieving the product superphosphate to remove the fraction having a particle size greater than 12 mesh.  Phosphoric acid is produced by passing an excess of sulphuric acid through a bed of the product superphosphate at a temperature of 10-85 DEG  C.  Ammonium phosphate produced by treating the phosphoric acid with anhydrous or aqueous ammonia may be added to a superphosphate-urea fertilizer mixture which is then granulated.

Abstract: 1470957 Closure of pressure vessels HICKSONS TIMBER PRODUCTS Ltd 5 April 1974 [6 April 1973] 16701/73 Heading F2P A pressure vessel 1 is provided with a door 2 which is held closed by mechanisms 3, 4, 5 mounted on the vessel body, operated by rotary cams 11 such that a resiliently compressive sealing means 9 is compressed to provide a seal between the vessel body 1 and the door 2. The holding mechanisms 3, Fig. 2, at the side of the door comprise shallow U-shaped members 6 which clamp around the door edge and a curb 8 of the vessel body 1. The position of the member 6 is adjustably defined, relative to the "open" position of the rotary cam 11, by a bolt 23 mounted in the rearward arm 18 of the member 6 and engageable with a cam-follower block 21. A rubber block 24 is positioned between another cam-follower block 22 and a plate 20 to take up adjustment of the position of the two camfollower blocks 21, 22. Rotation of the cam 11 about its axis 25 operates the holding mechanism 3. The holding mechanisms 4, Fig. 5 (not shown), are different from mechanisms 3 in that the U-shaped member (26) does not bear directly on to the door but instead engages an arm (29) of a U-section bar (30) secured to the door. The holding mechanisms 5, Fig. 6 (not shown), at the bottom of the door have the adjusting bolt 23 mounted on the forward arm 10 of the member 6 so as to be accessible from the front of the vessel 1, the rubber block 24 is dispensed with. A yoke (34) is slidably mounted on the arm 10 of the holding member 6 and carries a block (35) for engagement with the door 2; the member 6 is slidably supported on a plate (36). Figs. 7, 8 (not shown), show further embodiments with horizontally mounted cam-shafts (37). Generally a plurality of the holding mechanisms will have a common cam-shaft or alternatively a plurality of cam-shafts may be operated in concert. The door may slide as shown or may be hinged.

An apparatus for automatic analysis comprises two conveyors 1, 2, provided with vessel holders 7, 8 for sample vessels 5 containing liquid to be analysed and for reaction vessels 6, the conveyors moving so that their paths coincide at at least one point, 9, and being arranged to stop when each vessel holder in turn reaches point 9, the pipetting point and a device 11 (Figure 3) for moving the sample vessel or reaction vessel stopped at the pipetting point 9 towards a "self-rinsing" pipette 10 which draws liquid from a sample vessel 5 and pipettes off a measured quantity of it into the subsequent reaction vessel 6. Reagents may then be added and the reaction mixture in the tubes analysed, for example photometrically. The pipette comprises an N-shaped tube having a leg 12 into which the sample flows when suction is applied at 18, and check valve 16 which prevents air being sucked in through limb 15 while the pipette is being filled. The fixed volume of liquid in limb 10 is discharged into a reaction vessel by applying pressure through line 18.

Abstract: 717,373. Batteries. AKTIEBOLAGET TUDOR. July 7, 1952, [March 4, 1952.] No. 17080/52. Class 53. An accumulator is provided with a separator consisting of three layers 1, 2, 3 of glass fibres, the middle layer 2 being felted and being of finer texture than the outer layers which abut under pressure against the adjacent electrodes. The middle layer is free from any binding material while the outer layers may be held together by polystyrene or other binder. A temporary binder such as starch may be used with the middle layer to assist felting, the starch being removed subsequently by the acid of the accumulator. The edges of the three layers may be joined together by a thermoplastic material such as asphalt, polystyrene or polythene. The plates of the accumulator are of grid form, the frames and cross bars having circular cross sections. The frames may be coated with polythene or other plastic material and the lower edges of the plates may be covered with insulating tape to prevent short-circuiting by material deposited on the bottom of the accumulator. For the same purpose the middle layers of the separators on both sides of a plate may be extended beneath the plate as shown at 14 in Fig. 6, these extended horizontal portions being impregnated with a binding material. Specification 656, 111 is referred to.

Class 39(3) [Also in Group XXVII] An electrically operating device for igniting air fuel mixture comprises a resistance rod made of sintered silicon carbide or like sintered material adapted to stand high temperatures and corrosive media, the rod extending at least partly into and across the flow to be bathed thereby. The invention is particularly for ignition in turbojet units and other jet propulsion units and is applicable to aircraft. In Fig. 1 two rods 11, 12 of differing resistances are arranged side by side. An upper metallic terminal member 19 is supported by an insulating socket 21 and has sockets containing springs 13 pressing on the ends of the rods. Windows 23 are provided in the surounding metal casing member 22, through which the lower ends of the rods are earthed. When current is supplied the rod 11 of least resistance is heated up to red heat, but the rod 12 remains black or dark red only being simply heated. One rod could be used or several connected in parallel or to different voltages, e.g. 18-30 volts. The rods may be supplied by independent leads. In Fig. 4 fuel is supplied through jets 30, which have a direction roughly tangential to the cylindrical surface of the rod 27. The lower end of the rod is gripped by a split ring 31 compressed by screws 33 passing through the base of the casing 22.

Abstract: 1465626 Fluid pressure switches TOYOTA JIDOSHA KOGYO KK 19 April 1974 [21 Nov 1973] 17174/74 Heading H1N [Also in Division F2] A system for sending out a warning signal if deceleration of a vehicle is not consistent with the brake pressure applied due to, for example, overheating or water in a brake mechanism, comprises a switch mounted at angle on a vehicle body 40 by a bracket 39. Fluid pressure from the master cylinder 3 acts through an aperture 8 and chamber 9 on a diaphragm 10 which causes leftward movement of a member 18 carrying a contact 26 adapted to engage with a contact 33 of a leaf spring 31 biased to the right by a ball 35, the latter engaging the leaf spring 31 under gravity. Under normal braking contacts 26, 33 do not engage since vehicle deceleration in direction P causes ball 35 to move leftward under inertia and the natural leftward bias of spring 31 moves contact 33 away from contact 26. If the brake pressure does not give rise to an appropriate deceleration contacts 26, 33 do engage and a circuit is made through a terminal 17, battery 38 and switch body 1 causing a lamp or buzzer 37 to be activated. In an alternative embodiment, a weight is fixed to the leaf spring to replace the ball. In a modification of this embodiment, the inertia and brake pressure responsive parts of the switch are separated physically but are electrically coupled through terminals on each part. The inertia responsive part may have a screw (56) engaging the leaf spring to adjust the stress thereof.
