[Also in Division B1] A process for the continuous manufacture of phosphoric acid comprises treating natural phosphates with H 2 SO 4  and filtering the resulting mixture, part of the filtrate containing phosphoric acid being returned to the reaction mixture to maintain the fluidity thereof, the filtration being carried out by means of a continuous filter and a primary fraction of the filtrate containing phosphoric acid being collected separately from the remainder of the filtrate for return to the reaction mixture. The primary fraction may be collected near the point where the reaction mixture is poured on to the filter. The residue on the filter may be washed and the washings may be mixed with the primary fraction for return to the reaction mixture. Impurities in the phosphoric-acidcontaining filtrate may be removed by allowing the filtrate to cool and stand, with or without stirring. Alternatively, chemical precipitation of the impurities may be effected by addition of one or more precipitants, e.g. alkali metal (such as Na or K) and/or ammonium salts, e.g. carbonates and/or sulphates, calcium salts, e.g. phosphates or carbonates, barium salts or additional sulphate ions. When it is desired that the phosphoric acid shall contain alkali metal and/or ammonium phosphates, an excess of alkali metal and/or ammonium salt relative to the quantity necessary for defluorination and/or desulphation can be added, optionally with a salt of any other metal whose phosphate is required to be present. Flocculating agents and adsorbent substances, e.g. activated carbon, may be added to clarify the filtrate.

A cage for birds or small animals comprises a wirework body portion 1, forming the sides 4 and ends 5 of the cage, detachably secured to a rigid base 2, and a wirework top 3 detachably secured or hinged to the cage body 1, the sides and ends all being inclined to the base and hinged together with the axes of the hinge connections 6 passing through a common point so that when detached from the base, the cage body may be collapsed to a relatively flat condition. The connections 6 are formed by horizontally extending wires 7 of the ends 5 hooked around the upwardly extending wires 8 of the sides 4. The base of the cage is formed of channel members 11 supporting a removable tray 12 and the top 3 is attached to the cage body by means of hooks 9 formed from the wires of the cage body. The base 2 and cage body are secured together by clips 15. Brackets 18 moulded from plastics material are provided at the corners of the cage body and support glass screens 19.

Abstract: 1,090,961. Selective signalling. PLESSEY UK Ltd. Aug. 28, 1964 [Sept. 20, 1963], No. 37139/63. Heading G4H. A first winding of a transformer is selectively positioned relatively to a second, relatively long winding, by selecting one of a plurality of taps on the long winding and moving the first winding until a reference current passing through it induces equal and opposite currents in the two portions of the second winding demarcated by the selected tap, this being determined by arranging that the two portions of the second winding form two arms of a bridge. The arrangement may form part of a head positioning system in a multi-disc date storage system. Greater resolution can be achieved by also tapping the first winding and injecting the reference current at a selected one.

Abstract: 1,143,612. Mounting fifth-wheel couplings. INTERNATIONAL HARVESTER CO. 23 March, 1966 [6 May, 1965], No. 12778/66. Heading B7D. An attachment for mounting a fifth-wheel on a tractor 10 normally mounting at its front end a loader (24), Fig. 1 (not shown), comprises a pair of booms 40 pivoted transversely of the tractor on pins 16 for vertical movement, and rams 42 connected between further pins 18 and the booms, the fifth-wheel means 48 being pivotally mounted on transversely extending pins 50 attached to the free ends of the booms. The rod ends of the rams are connected to the booms via a transverse rod 44. In a modification Fig. 3 (not shown), a single ram (62) is connected between a pin (22) on the tractor and the midpoint of rod (44).

Abstract: 1,225,679. Printing apparatus; grippers. SCHNELLPRESSENFABRIK FRANKENTHAL ALBERT & CIE A.G. 31 Oct., 1968 [3 Nov., 1967], No. 51561/68. Heading B6C. A gripper oscillating system on sheet fed printing presses, which is controlled by a cam 10 on the impression cylinder 8 of the press is characterized in that an arm 20 which is secured on a shaft 1 of the system carries a roller 21 which, during a part of the revolution of the cylinder when a sheet is picked up at a feed table 7 is adapted to roll on an arcuate segmental surface 22 rotating with the impression cylinder to produce a tension in an adjusting train 11, 12, 13, 14, 1, 20, extending between the roller and the control cam. The roller 21 contacts the segment 22 to arrest movements of the arm away from the table.

Abstract: 1,226,871. Rotary vane pumps. N. WADDLETON. March 29, 1968 [Jan. 31, 1967], No. 5085/68. Heading F1F. In a rotary sliding vane pump comprising a rotor 15, Fig. 1, rotatable in an elliptical chamber 19 formed by a cam ring 10 flanked by side bushes 6, 9, Fig. 2, and provided with a plurality of axially-extending slots 16 slidably mounting vanes 18 and opening at their bottom ends into holes 17 which during the suction phase of operation communicate with a suction port 2 and during the compression phase with a discharge port 3 so that the vanes are always substantially in fluid balance to reduce friction and abrasion between the vane tips and the cam ring, the diameters of the holes 17 adjacent the bushes 6, 9 are increased in diameter to effect easier flow of the fluid into the holes, particularly during the suction phase of operation. The vane 18, are each an easy fit in its slot 16, Fig. 6, and formed with a knife edge, the pressure difference on the two sides of a vane acts to cast the vane in its slot to prevent leakage from hole 17. V-form grooves 27, 28, Fig, 7, 7, are provided on the forward ends of suction and discharge ports 7, 8 respectively and extension grooves 25, 26 at the forward and rear ends of ports 23 which communicate with the holes 17 to relieve shock on the vanes caused by sudden pressure changes and thus lessen pump noise.
