Title: Improvements in ball and tube mills of the multiple compartment type
IPC: B02C17/06
Filed: 1922-11-08
Abstract: 200,021. Smidth & Co., Ltd., F. L., (Smidth & Co., F. L.). Nov. 8, 1922. Ball and like mills.-In a ball or tube mill having two or more grinding-compartments through which the material passes, one or more screening-compartments each comprising a number of interconnected annular screening-spaces are arranged between the grinding- compartments. As shown in Fig. 1, the cylindrical screening-compartment 5 disposed between the grinding-compartments 2, 3 is provided with radial screening-surfaces 6, through which the fine material passes into an annular space 12 inside the shell 1 of the mill. Conveying-members 13 within the space 12 deliver the material into a space 14 at the end of the chamber 5. whence it passes by way of a central opening 15 into the grinding-compartment 3. The material retained in the chamber 5 is ground by grinding-bodies 17. The chamber 5 is formed by a number of double-walled screening-cages 18 with radial screening-surfaces 6, and may be adjustable longitudinally to vary the volumes of the grinding-compartments adjacent its ends. Fig. 2 shows a modification in which the screening- compartment 5 is annular and surrounds the grinding-compartments 3. The ground material passes from the grinding-compartment 2 through grates in the end wall 21 into a space 23 and thence into the screening-compartment 5. The finer particles pass through the screens 6 into the annular space 24 and thence through openings 26 into a double vane 28, one set of vanes discharging into the grinding-compartment 29 and the other set returning the coarse material to the compartment 3 for further grinding. The material ground in the compartment 3 passes through the screen 22 into the compartment 5. In another arrangement, Fig. 3, the annular screening-compartment 5 surrounds a portion of a progressively operating grinding-compartment 2, the rear portion 35 of which is separated from the remaining portion by a double wall 36, 37 having openings 38 for the passage of the grinding-bodies 4 and vanes for conveying the material retained in the compartment 5 back into the compartment 2 for re-grinding. The material passes from the compartment 2 through the grating 41 of the chamber 35 into the screening-compartment 5, from which the pipes pass by the chamber 24 and vane 28 into the grinding-compartment.

Title: Fsk modulator
IPC: H04L27/12
Filed: 1975-08-21
Abstract: 1488434 Data transmission; FSK modulators INTERNATIONAL BUSINESS MACHINES CORP 21 Aug 1975 [21 Nov 1974] 30551/76 Divided out of 1488433 Heading H4P Description of the embodiments is identical to the parent Specification, but the claims are directed to an FSK modulator of the type in which sinusoidal waves are synthesized digitally by successively summing, sets of incremental digital angular values ##, also increments of fractional baud time, then performing an ### to amplitude (sin#) translation through a previously calculated look up table, the digital amplitude values being converted to analogue form by conventional techniques. A clock 30 of frequency fs supplies anti phase outputs C1, C2 which are applied to address generator 31 also receiving three high order bits on buffer 32 and input data (D0). During C1 times, 8 values #T (T=baud time) are sequentially placed in adder 34 operating in conjunction with circulatory register 36 controlled through read/write memory 35 (clocked by C1, C2) hence 36 is sequentially "pumped up" by successive increments of #T. During C2 times angular 8 increments ##(T) are similarly treated with respect to register 37; after each addition, content of 36, 37 is inserted in 32. Add/subtract function is controlled by 38 so that: Output of 34 is passed through a 0 to sin # converter (i.e. ROM table) 41 to register 42 strobed by C2 pulses controlling a d/a converter, output being passed through a RC filter to line. The register 36 is prevented from over/under running when #T is added/substracted by arranging the 8 values to start at 000 with intermediate values representing equal steps of fractional baud time and terminating at 111. Register 36 may then be reset to 000. Similar considerations apply to the ##(T) values with respect to register 37.  Frequency changes at other than zero point are inherently averaged during the particular cycle which is illustrated in Fig. 1B (not shown) so that frequency changes occur in substantially continuous manner within a single baud time. The modulator may be changed to another group of frequencies by storing appropriate values in ROM 33 which are selectable by a control word LCW.

Title: Stabilization of polyolefins
IPC: C08C2/04
Filed: 1960-09-05
Abstract: Polymers of olefins, e.g. polyisoprene, containing residues of a catalyst consisting of an organo-metallic compound of a metal of Group I, II, or III of the Periodic System, and a compound of a heavy metal of Group IVb, Vb and VIb of the Periodic System, are stabilized by treatment with a hydrazine.  The Periodic System referred to is that shown in the Handbook of Chemistry and Physics, Chemical Rubber Publishing Company, Cleveland, Ohio, 33rd Edition (1951).  The hydrazine may be added to the polymerizate to terminate polymerization, or the hydrazine may be added to the polymerizate after the polymerization has already been terminated by the addition of a liquid containing a labile hydrogen atom. The hydrazine is selected from compounds of the general formula RR1NNR2R3 in which R, R1, R2, and R3 may each be a hydrogen atom, an alkyl, or an aryl hydrocarbon radical.  Compounds mentioned are hydrazine, and methyl, ethyl, and phenyl hydrazines.  The catalyst exemplified is aluminium triisobutyl and titanium tetrachloride.  The liquid containing a labile hydrogen atom may be an alcohol or ketone. The Specification contains an example of the vulcanization of stabilized polyisoprene.

Fig. 2. Cages 33 and 34 are each elevated by twin ropes, the pairs of ropes 29 and 30, and 52 and 31, each forming the two ends of a single rope passing to and round and driven by the driving drum (not shown). The ropes pass over pulleys 16, 13, 14, 15 mounted in pulley blocks 20,17,18,19 respectively. Pulley blocks 20 and 17 are loosely linked by pivoted rods 21 and 22 and these latter are pivoted about axes 23 and 24 respectively. Similarly, blocks 18 and 19 are linked and pivoted about axes 27 and 28. Hence if the tension of rope 29 is greater than that of rope 32 blocks 17 and 20 pivot about axes 23 and 24 and block 17 descends and block 20 rises so as to equalize the tensions. Likewise for blocks 18 and 19. The axes 23 and 24 may be coaxial and in a horizontal plane or they may be coaxial and parallel to the axes of the blocks, the blocks may have their movements changed by dash pots, or springs, or by friction ; and the pairs of ropes 29 and 32, 30 and 31 may be respectively tied to the ends of two horizontal rods, each of which is pivoted at its centre by a vertical rod to the respective cages 34 and 33. Fig. 4. Modification of Fig. 2. The blocks are formed into rigidly-connected compound blocks 35 and 36, and these two compound blocks 35 and 36 are pivotally connected by rods 37 and 38 rotatable about axes 39 and 40 respectively. Fig. 8. Modification of Fig. 4. The rigidlyconnected pairs 71 and 72 are guided for relative longitudinal movement by wheels 76 moving along guides 77 and the downward movement of 71 is caused to move 72 upwards by means of racks 73 and 74 coacting with rack wheel 75.
