Title: An improved picking conveyor for root crops
IPC: A01D33/04
Filed: 1950-02-27
Abstract: 689,320. Root-crop harvesters. SMITH, T. S. Feb. 27, 1951 [Feb. 27, 1950], No. 4966/50. Class 6(iii) [Also in Groups II and XXX] Apparatus for facilitating the manual separation of root crops from stones and clods of earth comprises a movable carrier in the form of a pair of endless roller chains connected together by cross bars or an endless belt provided with cross bars or projections on to which a mixture of roots, stones and clods of earth is adapted to be delivered in front of a rotary member which is driven in the same direction as that in which the end sprockets or rollers of the carrier are driven and which is mounted above the carrier with one end adjacent to the delivery point of the mixture and with its axis inclined to the direction of movement of the carrier in such a manner that most of the stones and clods of earth pass directly underneath the rotary member and most of the roots are deflected by the rotary member to a discharge station. Fig. 1 shows the application to a carrier consisting of a pair of endless roller chains 1 connected together by bars 3. The rotary member 5 .comprising a brush or roller is mounted on a shaft 9 journalled in brackets 8 on guards 7 and extends across approximately half the width of the conveyer. It may be driven by the same prime mover as the driving sprockets of the chains 1. The mixture of roots,.stones and clods of earth is delivered to the conveyer at 6 and carried towards the member 5. Most of the stones and clods of earth pass under the member 5 whilst most of the roots, such as potatoes, are rolled in and out of the stones and clods of earth when they come into contact with the member 5, and are deflected to the' other side of the conveyer and around the member 5. A partition 10 prevents the roots and stones becoming mixed after passing the member 5 Very small potatoes pass under the member 5 and large stones and clods of earth are are deflected around the end of member 5; these can easily be dealt with by the operators. The partition 10 may be replaced by a rotary shaft connected to the adjacent end of the member 5 by a universal coupling.

Healds and reeds, threading. - Relates to apparatus for selecting and separating warp threads in the preparation of the warp for looms for weaving of the type in which a carriage A, having a selector B with a hook device at one side and a separator C, is caused to travel past warp threads D suspended in a state of tension between top and bottom clamping members E, E' and consists in providing means for moving the bottom clamping members E<1> towards and away from a frame a and securing them in any adjusted position so as to increase or reduce the tension on the warp threads or move them entirely clear from the frame. In the construction shown, the frame a is the one on which the carriage A runs and the bottom clamping members comprise two bars, the front one of which is provided at each end with an L-shaped bracket E<2> having pivoted thereto a link E<3> of which the other end is pivoted at e to a bracket E<4> secured bv a screw E<5> to the back clamping bar. Projecting from the upper end of each bracket E<4> is a nut e<1>, which engages a screw e<2> rotatably mounted in a slot e<3> in an arm e<4> which is pivoted to the machine and connected by a link e<5> to a crank arm e<6> on a horizontal shaft e<7> actuated by a lever e<8> which carries a catch e<9> adapted to co-operate with a toothed quadrant e<10>. Movement of the lever e<8> in one direction or the other increases or reduces the tension on the warp threads, the lever being held in its adjusted position by engagement of the catch e<9> with the quadrant e<10>. The lower clamping members E<1> can be raised or lowered at one or both ends by turning one or both of the adjusting screws e<2>. The Provisional Specification describes a selector which engages each warp thread with a forward movement and transfers it with a diagonal movement to the separator, the movement of the selector in relation to that of the separator being so timed that the selector transfers a thread on to the separator whilst the latter is making its forward or spacing movement and commences its return stroke before such forward movement is completed. Means are also provided whereby any thread that the selector fails to transfer is prevented from getting behind any of the remaining threads, such means comprising a deflecting plate mounted on the carriage so as to push back the foremost unselected warp threads as the carriage travels past them. Specification 7780/15 is referred to in the Provisional Specification.

Title: Improvements in the manufacture and production of di-ammonium phosphate
IPC: C01B25/40
Filed: 1926-02-22
Abstract: 256,137. Johnson. J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 22, 1926. Ammonium phosphate.-In the production of di-ammonium phosphate by the interaction of ammonia and phosphoric acid a ratio of 1 molecule of phosphoric acid to 1.5-2 molecules of ammonia is maintained, the further additional quantity of ammonia when required being introduced during or after cooling the solution. Phosphoric acid may be added to a solution of diammonium phosphate until the ratio of 1 molecule of phosphoric acid to 1.5 molecules of ammonia is obtained and ammonia and phosphoric acid and then introduced in the same ratio. Water is evaporated owing to the heat of neutralization and when the solution is sufficiently concentrated it is withdrawn continuously or at intervals. After cooling, ammonia is added to precipitate the di-ammonium phosphate. When stronger phosphoric acid is used, to avoid too high a temperature aqueous ammonia may be introduced with the phosphoric acid. Heat may be supplied when weak acid is used, and to facilitate evaporation reduced pressure may be employed. In a second example, dilute crude phosphoric acid obtained by decomposing rock phosphate by means of sulphuric acid is treated with ammonia until the ratio of 1 molecule of phosphoric acid to 1.5 molecules of ammonia is obtained. A mother liquor containing di-ammonium phosphate from a subsequent step is then added. After evaporation a further quantity of ammonia is introduced in order to give the di-ammonium phosphate, which separates in the crystalline condition, leaving a mother liquor for re-use. Before the final treatment with ammonia, impurities such as iron and aluminium compounds may be removed by filtration.

Title: Improvements in or relating to machines for attaching heels to shoe sole members
Inventor: ELLIOTT HAROLD ERNEST
IPC: A43D25/12
Filed: 1960-02-15
Abstract: 973,611. Attaching heels to soles. BRITISH UNITED SHOE MACHINERY CO. Ltd., H. E. ELLIOTT, and S. F. LINTOTT. Feb. 14, 1961 [Feb. 15, 1960; Feb. 4, 1961], No. 5244/60. Heading A3B. A machine for attaching together a heel H and a shoe sole S prior to their attachment as a unit to a shoe comprises pressure applying mechanism for clamping together the breast face of the heel and a heel breast flap of the sole at an operative station and a movable support 8 for carrying the heel and sole and means for positioning them relative to each other between a loading station in which the heel and sole are positioned on the support and the operative station. In the construction shown the support 8 carries a template 34 positioned in guideways provided in the support, which template determines the position of the sole S and the heel H relative to each other. Two piston rods 70 and 72 extend from conventional air operated piston and cylinder devices, the former clamping a resilient abutment 76 over the back-curve edge of the heal seat by a V-shaped notch 82 in the abutment, and the latter clamping the resilient abutment 78 against the back of the heel adjacent to the heel top-piece. These abutments press the sole-flap F and the heel breast against a stationary adjustable shaped presser member 41. The abutment 76 is adjustably mounted for heightwise movement and the stationary presser member 41 is demountable from its holder 50 by two pins 52. Two templates may be used side by side to provide the support 8 with two stations, interchangeable by lateral sliding of the carrier, i.e. a loading station and an operative station. In the operative station the support 8 is tilted by a treadle operation (Fig. 1, not shown) against spring loading so that the heel breast and sole flap F, having their interfaces coated with adhesive, press against the stationary presser member 41. This movement operates a valve which allows air to pass into the aforementioned cylinders which drive the pistons 70 and 72 with their respective abutments 76 and 78 against the back of the heel thus effecting a uniform bond over the whole area of the heel breast and sole flap in contact.
Patent GB-375735-A (GB)
Title: An improved process for the production of artificial silk of dull lustre
IPC: D06M13/188
Filed: 1932-02-22
Abstract: In a process for the production of viscose silk of reduced lustre, a salt of an organic acid with a base which forms an insoluble sulphate, for example, a barium, strontium, calcium, or lead salt, is dissolved in a volatile organic liquid, and emulsified in an amount of 0,2 to 2 per cent in the viscose, which is then spun into a sulphuric acid bath and finished in the usual manner.  Thus, no solid particles pass through the spinning nozzles, and the insoluble sulphates in the product are present at those points which were previously occupied by the particles of the emulsified liquid. Suitable volatile organic liquids specified are benzene and its homologues, terpineol, and tetrahydronaphthalene.  In an example, a solution of barium oleate in terpineol is emulsified in viscose which is spun into a salt bath containing sulphuric acid.  The terpineol is almost entirely removed during the usual finishing treatment.  In other examples, the solutions to be emulsified in the viscose consist of a solution of strontium oleate in benzene containing a small proportion of methyl cyclohexanol, a solution of barium ricinoleate in benzene, and a solution of strontium oleate in terpineol.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the application of the process to spinning solutions in general. This subject-matter does not appear in the Specification as accepted.
