Title: Improvements in and relating to electrical control systems for elevators, hoists andthe like
IPC: B66B1/52
Filed: 1930-06-14
Abstract: 357,176. Master control of D.C. motors. WARREN, T. R., Beechwood, Gaskell Road, Altrincham, and SMITH, G. D., Clevedon, Brooklands Road, Brooklands, both in Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London. June 14, 1930, No. 18268. [Class 38 (iii).] Varying electromotive force.-A control for an elevator, such as a balanced cage elevator for a mine, has a drum controller A driven by the wind. ing drum, and operative to determine the sequence of closure of accelerating contactors as the cage leaves a level and to determine the sequence of opening as the cage approaches another level, and means are provided to adjust the controller so that the period of closure of the contactors is varied to suit the extent of travel of the cage. For travels between the top and intermediate levels an auxiliary switch S is in the position shown. Closure of pushbutton PB1 causes energization of contactor coil OC2 over controller contacts B1, B2, the coil then being maintained over interlock CX2, and the contactor contacts C2 connecting a Ward-Leonard generator field F through resistance R to the supply. As the cage moves, so does the drum A, and contactor coils OC3, OC4, OC5 are energized in succession, the contactors shorting portions of the resistance R. Towards the end of the travel drum segments D7, D6, D5 leave brushes DB7, DB6, DB5, and the contactors open in the reverse sequence and finally limit switch LS2 opens and the cage stops. Another closure of pushbutton PB1 causes energization of reverse contactor coil OC1 over contacts DB1, DB2, DB3, limit switch LS1 now being closed, the cage and drum then travel in the reverse direction. For operation between the top and bottom levels, switch S is moved to render pushbutton PB2 operative and the brushes DB1 .. DB7 are moved closer to the brushes B1, B7 so that the drum has to rotate further between the energization and de-energization of the contactors OC3, OC4, OC5. The brushes DB1 .. DB7 can be moved by a differential gear operated by relative movement of the two winding drums when these are being adjusted to give a different travel to the two cages. In a modification, two drum controllers are used, driven in opposite directions and the contactor coils connected between corresponding brushes on each. Adjustment for different travels is effected by altering the relative positions of the two controllers. In a further modification, a single drum controller is rotated by a segmental gear on one winding drum during the initial part of the travel of the cages and is returned to its normal position by a segmental gear on the other winding drum during the final part of the travel of the cages, adjustment for different travels being effected by altering the relative position of the segmental gears.

Title: Improvements in or relating to animal foods and methods for the preparation thereof
IPC: A23K1/00
Filed: 1932-07-01
Abstract: 405,283. Food for animals. YEASTIES PRODUCTS, Inc., Irwin, Pennsylvania, U.S.A. -(Assignees of Spohn, R. C. ; 50, West 67th Street, New York, and Luke, C. E. ; Irwin, Pennsylvania, both in U.S.A.) July 1, 1932, No. 18691. Convention date, Oct. 29, 1931. [Class 5 (ii).] A method of preparing an animal food from cereals which have been cooked in the presence of moisture, flaked and toasted to such a temperature that the vitamin content of the cereal has been destroyed to obtain a brittle cereal as the result of the conversion of the starches to dextrines and sugars, comprises mixing the toasted cereal with any desired ingredients and treating the mixture with a substance containing vitamins B<1> and B<2>. The vitamin-containing substance may be yeast which may be irradiated so as also to comprise vitamin D. Meat, salt, bone meal, buttermilk, soya bean meal, alfalfa and flavouring and medicinal preparations may be included in the food : the flaked toasted cereals may be small particles of corn flakes, rice flakes or bran flakes, such small particles either being derived from grinding up toasted cereal foods or resulting from breakage in manufacture for human consumption : scorching of the cereals produces a desired charcoal content in the food. Dry yeast may be used, in which case the ingredients are placed in a hopper 1 and moisture is supplied thereto through a spraying device 3. The moistened ingredients are fed by a conveyer 2 to a vertical mixing chamber 4, of the form shown, in which rotates a mixing screw 5 of progressively increasing diameter. A pipe 10 delivers from the mixing chamber 4 to an elevator 12, whence the mixed materials pass, through a hopper 15 and shoot 16, to a moulding press. The latter comprises a revolving die 17, stationary bed plate 18, die plunger 19 and knock-out plunger 22. The plungers are connected through rocker arms 27 and links 28 to intermittently driven timing cams 29. The food may, however, be packed directly from the shoot 16 without being compressed. The die 19 may impress a trade mark on the biscuits. Alternatively, the dry yeast may be omitted and the formed biscuits passed through an aqueous suspension of yeast and dried, in the apparatus shown in Fig. 5.
Patent GB-737520-A (GB)
Title: Improvements in processes for the production of white calcium cyanamide
IPC: C01C3/18
Filed: 1953-07-06
Abstract: Calcium cyanamide is produced by fluidizing calcium carbonate in a stream of gas comprising ammonia at a temperature of for example 400-850 DEG  C.  The temperature may be lower if the calcium carbonate is in very finely divided form.  The water vapour produced by the reaction is removed as quickly as possible and the partial pressure thereof in the reaction zone maintained as low as possible, i.e. by employing rapid gas flow and an ammonia gas stream diluted with inert gas, for example carbon dioxide, flue gas, electric furnace waste gas, hydrogen or nitrogen.  These gases also inhibit ammonia decomposition.  Solid ammonia decomposition inhibitors can be mixed with the calcium carbonate, for example silica gel, active carbon, alumina or calcium sulphide.  The reaction may be effected in and around pipes coated with an ammonia decomposition inhibitor, e.g. pure aluminium or fused or powdered aluminium oxide.  A number of fluidized beds arranged in series may be employed.  A gas flow of at least 2 cm./sec. and a proportion of ammonia in the gas of below 50 per cent may be employed.

In the embodiment shown, the rod 23 is made of spring steel and is attached to a knob 17 for moving bolt 14 from a retracted to a projected position to lock closure members 11, 12, Fig. 1, (not shown). The rod is maintained in the projected position by means of ball 27 urged into engagement with the rod by a spring 28. A conductor 26 connects the alarm circuit to the contact ring 25 and a second conductor 29 is connected from the alarm circuit to a conductive sleeve 22 slidably supporting rod 23, the alarm circuit being closed by flexure of the rod along its length between the bolt 14 and sleeve 22 to cause engagement of bolt 14 with ring 25. The alarm circuit maintains an audible signal until a set of contacts 31 are coupled by operation of a switch blade 32. In an alternative construction, the bolt is part of a key operated lock. In a further embodiment Figs. 6, 7 (not shown), bolt (72) is reciprocated on rods (86), (87) upon rotation of a sleeve 94 by a thumb turn (97) or by the rotatable plug of a pin tumbler, cylinder lock (99) and the circuit is energised when a force is applied transverse to the axes of rods (86), (87) so that bolt (72) engages conductive strips (102) (103) connected to the alarm circuit.
Patent GB-779811-A (GB)
Title: Process and apparatus for the granulation of fertilisers and the like
IPC: C05B19/00
Filed: 1952-07-24
Abstract: <PICT:0779811/III/1> In the granulation of thin pastes containing a large liquid phase, especially those resulting from acid attack on phosphate rock in fertilizer manufacture, the granulated product is divided into coarse, fine and product fractions; the coarse fraction is recycled to the process at a point where the paste is sufficiently liquid to partially dissolve the coarse grains, whilst the fines are recycled to a point where the paste is sufficiently concentrated to crystallize on the fines and increase their size. As shown in the drawing, a paste resulting from the nitric acid attack on phosphate rock is introduced into a vat 1 where it is reacted with ammonia in the presence of recycled coarse grains fed at 3.  The resulting paste is fed by line 5 to a concentrator 6 which is also fed with coarse grains by line 7, and is subjected to a hot air blast 8.  The past overflows to a mixer 9 where it is mixed with fines from line 10 and thence to a granulator 12, which may be fed with crushed product size granules through line 14. The granulated material passes to a drier 15 and from thence to a screen 16 which separates coarse particles for recycling at 3 and 7, the remainder passing through a cooler 17 to a further screen 18 which removes product size grains at 20 and recycles fines through line 10.  Any excess of product size particles over a predetermined figure overflow from a weighbridge 19 to a crusher 22 and the fine particles produced are recycled through line 14 to the granulator 12 whereby the quantity of recycled material is kept constant.  Additional fertilizer ingredients such as potassium chloride may be introduced through line 13 into the granulator 12. According to an example in order to obtain a dicalcium phosphate/ammonium nitrate fertilizer, a phospho-nitrogenous paste prepared by the action of nitric acid on natural phosphate and removal of part of the calcium nitrate formed by physical means or by the addition of sulphuric or phosphoric acid, is treated at 105 DEG C. with gaseous ammonia in vat 1 and the paste is then fed to the vat 6 at 90 DEG C. where hot air at 250 DEG C. is passed thereover.  The cooling in the crystallizer 9 may be effected by the addition of cooled recycled fines but in addition a cold air jet 11 may be employed to keep the temperature below 70 DEG C.  The coarse grains, of over 4 mm. size are removed by screen 16 and the product size grains of 2-4 mm. size are removed at 20.
