Title: Improvements in or relating to the manufacture and production of fertilisers
IPC: C05B1/02
Filed: 1931-01-21
Abstract: A solid fertilizer is directly obtained by treating rock phosphate with an ammonium-sulphate sulphuric-acid solution in which the ratio of free acid to water corresponds to an acid concentration of at least 54 DEG  B<\>ae, and ammoniating the resulting solid product with ammonia.  The ammoniation may be carried out in stages and the ammonia may be aqueous or anhydrous gaseous or liquid ammonia.  When the solid intermediate product is to be treated with anhydrous ammonia sulphuric acid of 54-60 DEG  B<\>ae may be used for the acid treatment but when the solid intermediate product is to be treated with aqueous ammonia sulphuric acid of 64-66 DEG  B<\>ae may be used. The quantity of sulphuric acid used may be sufficient to react with the non-phosphatic ingredients of the rock and to convert the tricalcium phosphate in the rock to monocalcium phosphate.  The ammonium-sulphate sulphuric acid solution, which may contain 1/5 -\ba1/2 molecular proportion of ammonium sulphate per molecular proportion of sulphuric acid, may be prepared by partially neutralizing sulphuric acid with anhydrous liquid or gaseous ammonia or even with aqueous ammonia if the amount of water introduced is not too great.  Other fertilizing or inert materials may be added before or after the treatment with sulphuric acid or subsequent ammoniations.  Specifications 239,551, [Class 111, Sewage &c.], 340,120, 347,974, and 359,020 are referred to.  According to the Specification as open to inspection under Sect. 91 (3) (a) the solid intermediate product may be used as a fertilizer without ammoniation. This subject-matter does not appear in the Specification as accepted.

IPC: A23D9/02
Filed: 1936-01-22
Abstract: <PICT:0460814/III/1> <PICT:0460814/III/2> An apparatus for emulsifying and for other purposes, comprises a casing enclosing two rollers provided with left-hand and right-hand threads which intermesh and thereby wholly or partly close the passages between the threads.  The rollers 1 are geared together by gears 12, and as they rotate the treated substances in the passages 3 are urged forward. The thickness of the threads 2 is slightly less than that of the passages 3, so that the rollers may be given an axially reciprocating motion and so that some of the material may pass back through the spaces 13 for further treatment.  The materials to be emulsified enter the apparatus through a pipe 10 and leave through pipe 11 where the rate of discharge is controlled by a stop cock.  The rollers are rotated at such a speed that the emulsion tends to be discharged faster than the stop cock will allow.  The emulsion is forced back p through the spaces 13 whereby the emulsifying effect is enhanced. A jacket 5 may be provided on the casing 4 for heating and cooling purposes and heating and cooling liquids may be passed through the interior of the rollers.

Title: Double lift loom dobbies
IPC: D03C1/22
Filed: 1963-01-18
Abstract: 1, 035, 823. Loom dobbies. E. TRUMPELT [trading as ERICH TRUMPELT TEPTILMASCHINENFABRIK]. Jan. 18, 1963 [Jan. 20, 1962], No. 2414/63. Heading D1E. In a double lift dobby for looms upper and lower draw hooks are adapted to be actuated by lifting bars 31, 31a through hook needles 22 and 12 respectively under control of a pattern card 1. The card 1 which passes over a cylinder 2 has pairs of rows of holes along its length which are alternately probed for odd and even picks by a pair of needles 3, 3<SP>1</SP> arranged one behind the other in the direction of movement of the card. The needle 3 is provided for normal forward rotation of the loom, the needle 3<SP>1</SP> being rendered ineffective whilst for reverse rotation of the loom for pick finding the needle 3<SP>1</SP> only is effective to provide a correct shed sequence in this direction. The reading needles 3, 3<SP>1</SP> are coupled to driver needles 6, 7 which are adapted to be driven by successively operated driving bars 4, 5 respectively for their hook ends 8, 9 to actuate abutments 10 or 21 on auxiliary needles 11 coupled to the hook needles 12 and 22 respectively. The needles 3, 3<SP>1</SP>, 6 and 7 are carried on a rack member 17, 20 which is adapted to be moved laterally by cam discs 25, 26 after each pick for the reading needles 3 to align alternately with the adjacent row of holes of each pair of rows. The ends 8, 9 of the driver needles 6, 7 also align alternately with an abutment 10 or 21 of auxiliary needles 11. Thus the upper and lower draw hooks are alternately controlled by their respective row of holes of the pattern card. Dropping of either needle 3 into a hole in the card will cause actuation of the respective drive needle 6 or 7 by its driver bar to actuate the aligned auxiliary needle 11 and move the hook needle 12 or 22 out of the path of its lifting bar. The timing of the driving bars 4, 5 and lifting bars 31, 31a is such that the dropping of needle 3<SP>1</SP> in the forward rotation of the loom is ineffective whilst on reverse rotation the needle 3 is ineffective. After the completion of each reading the needles 3, 3<SP>1</SP> are lifted from the card by cross wires 16 and lowered for the next reading, the card being stepped along during the lifting of the needles. The driver needles 6, 7 are loosely carried in holes on bar 20 of rack 17 so that they can pivot in a vertical plane. Springs 32 assist their return action action and that of the reading needles on to the card.
