Title: Process and apparatus for treating plant material for the removal of incrusting materials from the fibre thereof
IPC: D21C7/14
Filed: 1926-06-04
Abstract: 255,029. Fish, F. K. July 7, 1925, [Convention date]. Pulp, preparation of.-In treating plant material for the preparation of pulp, the material is treated in a digester with liquor containing solvent extractives of such material with or without an added chemical and withdrawing the liquor from the bottom of the digester and spraying it on to the top of the material during the charging of the digester and during the successive stage of the process. Liquor is first introduced into the digester 1. the material is then fed in and the liquor is circulated by a pump 2 to spray on to the material during charging. The apparatus is then sealed and the pressure reduced to 13-20 inches by a vacuum pump 6 and the circulation by the pump 2 continued. After saturation. a full charge of liquor containing solvent extractives from the tank 13 is admitted through the valve 15, and the temperature raised to 212‹ F. for 30 minutes. The temperature is then further raised to approximately 250‹ F. for 10 minutes by steam through a valve 16 and the valve 15 is then closed. When the treatment of the material is completed, the contents of the digester are discharged into a blow pit 7. Vapours and gases containing valuable extractives are released to a condenser 10 and the condensate therefrom passes to the supply tank 13 for a subsequent operation. The process is applicable for the sulphite treatment, and added chemicals may be alkali, acid, or neutral in character.

Title: Means for stabilizing the calcium ion concentration of aqueous solutions or suspensions of mineral cores
IPC: C22B3/00
Filed: 1961-04-19
Abstract: <PICT:0982693/C1/1> Carbon dioxide-containing gas is passed into an aqueous solution or suspension of a mineral ore to lower the pH and so stabilize the calcium ion concentration.  The CO2 is preferably obtained from the combustion products of furnaces, I.C. engines &c. In the arrangement shown, the solution or suspension passes through the upper level 21a of a trough over the porous diaphragm 22.  A pipe 12 supplies CO2 to a compartment 23 below the diaphragm through a manually-controlled valve 26.  If the pH depression is insufficient, pH-sensing electrodes 31, 33 open valves 27, 28 to admit CO2 to further compartments 24, 25. If the pH depression step is performed after froth flotation, a short time anti-foaming agent is added to the slurry to prevent foaming during admission of the CO2; if the pH depression step is performed before froth flotation, the frothing is effected with CO2 instead of air.ALSO:In a mineral treatment process in which a slurry is treated with a CO2-containing gas to stabilize the calcium ion concentration (see Division C1), any subsequent froth flotation is effected using CO2-containing gas as the aeration agent.

Abstract: 111,274. Beardmore & Co., W., and Methven, T. F. Oct. 4, 1917. Reversing; starting.-A compressed-air distributing-valve for starting in either direction consists of a piston, which can be thrown in either direction from mid position by compressed air, and is then reciprocated by a tappet on a part of the engine moving at engine speed. In the form shown, the piston valve A has a central diaphragm B and ports F, G, H, I coacting with ports J, L, K, M in chambers N, O, which are connected by pipes P, R to the engine cylinders. A pin S in the piston diaphragm B passes through a slot in the casing and engages a lever T pivoted at U and held in mid position by a spring. A jaw V on the end of the lever is engaged by a pin W on an eccentric strap X, when the lever is thrown in either direction from mid position, in order to oscillate the lever and the piston valve. The strap X may be that by which the engine fuel and water pumps are driven at starting, compressed air is admitted to either side of the piston by means of a hand-wheel N<1>, the stem of which carries a cam F<1> adapted to engage one or other of the compressed-air valves A<1>, B<1> leading by pipes D, E to the piston casing. The valve ports F, G register in turn with the ports J, L, supplying compressed air to the pipes P, R in turn, and the valve is moved between the two positions, by means of the jaw V and pin W, until the valve A<1> or B<1> is closed by pushing up the stem G<1> of the hand-wheel N<1> until it is held by a catch L<1>.

Title: Winding arrangement for dynamo-electric machines
IPC: H02K3/28
Filed: 1930-05-30
Abstract: 353,569. Windings for dynamo-electric machines. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. May 30, 1930, No. 14581. Convention date, May 30, 1929. [Class 35.] For laying out a winding in a slotted core which has a number of slots greater than that corresponding to the number of conductors in the winding, the maximum number of available conductors is distributed uniformly in the slots to form an assumed part winding having symmetrical phase bands, and this process is repeated the requisite number of times with the remaining conductors, the conductors being connected together to produce a complete winding. Considering a two-layer winding having 96 bars (i.e. 48 per layer) which are to be placed in a 60-slot core, there will be 24 " dummy " bars. The greatest number of the 48 bars which can be distributed uniformly is 30, so that in each layer there will be one bar in each alternate slot. This constitutes the first assumed part winding. Of the remaining 18 bars per layer, the greatest number which can be accommodated uniformly is 12, i.e. a bar in every fifth slot. The residual 6 bars per layer can be distributed uniformly, i.e. a bar in every tenth slot. In a two-pole, three phase, machine there will be 10 slots per phase band or zone, and the numerals 1 .. 10 in the upper line of the Figure indicate the slots originally assigned to a phase band. In the two lines I are shown the bars for the two layers of the first assumed part winding. A slot pitch of 5/6 i.e. twenty-five slots is selected for the winding and the layers of conductors are relatively staggered by five slots. The second part winding shown in the next pair of lines II has a slot pitch of twenty-six which approximates as nearly as possible to that desired and the conductors of the two layers are staggered by four slots. In the next two lines III the two bars of the third part winding are shown with the bars staggered by five slots corresponding to a slot pitch of twentyfive. In each part winding the conductors are symmetrically disposed about the centre line of the original phase band. The two last lines IV show the conductors of the three part windings assembled in the slots and the conductors of succeeding phase bands are similarly arranged. The bars are connected in star to form a complete winding. A winding is described, Fig. 2 (not shown), with an arrangement of conductors exactly the same as in the lines IV of the Figure but employing a slot pitch of twenty-eight so that the end conductors (which may be of the evolute type) are all equal and therefore similar coils may be employed throughout the winding. The slots occupied by single conductors may contain additional insulation so that these conductors may be at the maximum voltage. The object of the invention is to improve the armature field form but if the ideal form of curve is not required, the first part winding only need be distributed symmetrically.
