Reference has been directed by the Comptroller to Specifications 684,296, 769,498 and 795,894.ALSO:Polysubstituted ammonium silicon compounds containing the grouping <FORM:0882053/IV (a)/1> where R is alkyl, aralkyl, or nitro-, alkoxy- or halo-aralkyl, X is halogen, a is at least 3, s is 1 to 3, t is 0 to 2 and s+t is 3, are prepared by reacting a halide RX with an aminoalkyl silicon compound having the grouping H2N(CH2)aSi­.  Th compounds which are claimed have the above formula where the remaining silicon valencies are satisfied by alkoxy radicals with or without alkyl or aryl radicals; but polysiloxanes are included. The polysiloxanes may also be prepared by hydrolyzing the ammonium silanes.  The starting silicon materials are described in Specifications 882,054, 882,062, 882,069 and 882,096.  Suitable halides are methyl, ethyl, propyl and benzyl chlorides, methyl and p-chlorophenethyl iodides, and ethyl, butyl and anisyl bromides. The yield of tri- and tetrasubstituted ammonium salts is increased if the hydrogen halide by-product is removed as it is formed, e.g. by reacting under reduced pressure.  Temperatures of -5 DEG  to 150 DEG C. are specified, and organic solvents may be present, e.g. alcohols, ethers and hydrocarbons, some of which appear to influence the degree of substitution on the nitrogen atom.  The examples describe the preparation of (1) <FORM:0882053/IV (a)/2> , (2) <FORM:0882053/IV (a)/3> and (3) <FORM:0882053/IV (a)/4> , and (4) the use of (1) as an anti-foam agent.  The Specification also refers to the reaction of gamma-aminopropyl polysiloxane or the cyclic tetramer of delta-aminobutylmethylsiloxane with an alkyl or aralkyl halide.

Title: A method of and apparatus for the preparation of sugar cane stalks prior to the extraction of juice therefrom
IPC: C13B10/02
Filed: 1925-12-14
Abstract: 267,235. Morgan, W. H. Dec. 14, 1925. Extracting sugar.-Previous to the juice extraction, sugar canes are washed and cut into short lengths which are then reduced to a fibrous haylike mass. In one form, Fig. 1, the canes are fed to the hopper 12 of a washing tank 9 and are moved round therein, as indicated by the arrows, bv a conveyer 13 so that their waxy covering substance and the sand and other dirt are rubbed off. The conveyer 13 is formed of a series of looped, preferably sprocket, chains having gripping fingers 15. The chains are mounted on shafts 14, 14a, shaft 14 being driven, e.g. by a motor, and shaft 14<a> being driven from shaft 14 by a belt or chain 16. Water or other washing fluid is supplied to the tank 9, leaves &c. being removed through an overflow 17<a>. The sludge is removed from the bottom of the tank 9 by a pump 21. A conveyer 17 preferably mounted on shaft 14 and similar to conveyer 13 raises the cleaned canes to a hopper 18 containing circular saws 22 which cut the canes into lengths of about six inches. The cut sections fall through a hopper 19 to a disintegrator 27 where they are shredded longitudinally to a fibrous hay-like mass which may be fed by an air blast through outlet 28 to juice-extracting rollers. Solid polished steel or other smooth rollers may be employed for the extraction. Instead of extracting the juice immediately, the fibrous mass may be dried, bundled, and stored for extraction later, and in this condition can be transported to a central extraction factory. In another form, Fig. 4, the washing tank 9<a> has a paddle wheel 29 to circulate the water and draw the canes towards a roller 30 having radial fingers 31 which lift the cleaned canes from the tank to a discharge outlet 28. The tank has a diaphragm 33a forming a false bottom. Bars 33, partly surrounding the lifting roller 30, extend from the rear end of diaphragm 33a to the discharge outlet 28, the lifting fingers 31 operating between the bars. The tank mav have an end opening and spout through which leaves and other light impurities are removed.

Abstract: 251,896. Knorr Bremse Akt.-Ges. Dec. 16, 1925. Addition to 244,779. Valves controlled by pilot or relay valves; locking.-An actuating mechanism for the reversing gear of feed-water heaters used on locomotives is controlled by an auxiliary valve and is provided with spring loaded locking catches for securing the actuating piston in its extreme positions so that the actuating cylinder may be relieved of pressure. The locking catches p<1>, q<1> co-operate with holes n, o in the piston rod h and are carried by pistons p, q loaded by springs w, v and working in cylinders f, g. When it is desired to actuate the piston the control valve a is moved to connect the supply conduit r to one or other of the pipes c, d so admitting fluid pressure to one or other of the locking cylinders. This moves the piston against the action of the spring to unlock the catch and at the same time uncovers a side port in the locking cylinder to admit fluid pressure to the appropriate side of the main cylinder. On the piston reaching the end of its stroke the other catch springs into engagement with its corresponding recess in the piston rod.
