Title: Improvements in rolling mills
IPC: B21B41/04
Filed: 1964-07-10
Abstract: 1,076,205. Continuous rolling. MORGARDSHAMMARS MEKANISKA VERKSTADS A.B. July 10, 1964 [July 10, 1963], No. 56503/66. Divided out of 1,076,204. Heading B3M. A continuous rolling mill for rod, wire and strip includes a number of mill units each consisting of a first stand, having rolls 52, 53, and a second stand with rolls 50, 51, the first stands forming an aligned train and being connected by repeaters 31, 32 to the second stands. Material passing from the aligned train to a second stand passes beneath a first stand, Fig. 3 (not shown), and through a repeater (31). A repeater (32) returns the material to the first stand of the same unit. In each unit the rolls of the two stands are staggered, the rolls (50) and (52) being in alignment. This allows normal driving of the roll pairs by their respective motors (57) and (61) and gear-boxes (56) and (60) and also allows each of the rolls (52) and (53) to be driven by a separate motor. In this latter case the roll (53) is driven by motor (61) through gear-box (60), and roll (52) is driven by motor (57) through gear-box (56), coupling (54), roll (50), and disconnootible coupling (63), the coupling (59) being disconnected. Different roll diameters can thus be used for the two rolls (52) and (53). The rolls of the second stands can be vertically disposed if desired.

The sides 22 each have a central stacking projection 84 at the top and a complementary recess (88) at the base and the sides 24, which are twice as long as sides 22, each have two stacking projections 86 and complementary recesses 90 so positioned that one container can be stacked in vertical alignment with an indentical container, or with one half of the container in vertical alignment with one half of an identical container, the other half of the container projecting outwardly from one end or either side of the other container. The corners of the sides are cut away as at 26, (36) to allow the sides to be moved to the resting position. The sides 22, 24 have downwardly facing stop surfaces (96), 98 which abut the projections 84, 86 of a similar container in which it is nested to prevent wedging. The lower parts of the sides 22, 24 are flared slightly outwardly at 94 to bring the recesses (88), 90 into alignment with the projections 84, 86 in the stacking position. The end edges of the connecting portions (56), 66, have inner edge structures (76, 80) respectively which interengage in the stacking position and outer end structures (78, 80) which interengage in the nesting position. The container is moulded in the nesting position and is thus self-biased towards this position by the phenomenon of plastic memory, but is also held in the stacking position by the inward torsional action of the structure 12 on the sides and connecting portions (56), 66, the latter being inclined at an angle of less than 180 degrees to the central portion 50 in this position. Hand holes 30 are provided in sides 22. The sides are of apertured construction, having strengthening ribs 28.

Title: Process for extracting coal
IPC: C25B3/13
Filed: 1966-12-22
Abstract: <PICT:1122510/C4-C5/1> In a method of making a de-ashed coal extract (for subsequent coking) by a solvent extraction process, the powdered coal is initially mixed with a solvent low in polymerizable impurities and having a B.R. of 315 DEG  to 482 DEG  C. (600 DEG  to 900 DEG  F.), and after heating and separation of suspended solids, the solvent and the extract are separately recovered under conditions controlled so that a predetermined volatile content is left in the extract.  The solvent is obtained by refractorizing (i.e. removing the less refractory components from) a high boiling coal tar distillate or cracking and refractorizing certain clarified slurry oils. Crushed coal and solvent in a ratio of 1:1 to 1:4 by weight are mixed at 14, digestion occurring at 18, 20, and separation of solids at 24.  De-ashed coal and solvent are separated either by a vacuum distillation process, (parts 42 . . . 66), or by solvent precipitation, (parts 68 . . . 118), coal emerging at 52 and from the bottom of a tower 94, and solvent (for recycling) at 60 and 118.  The volatile content of the de-ashed coal is controlled by controlling operating conditions in heater 46 and vacuum product drum 48, and by suitable choice of precipitation solvent (e.g. its B.R.), temperature control of this solvent (at 108, 116) and solvent to coal ratio (at 74). The precipitation solvent comprises a controlled mixture of recycled gas oil from 110 and gasoline from gas separator 100 (via 72).

Filed: 1973-12-13
Abstract: 1422838 Luminescent screens HITACHI Ltd 13 Dec 1973 [25 Dec 1972] 57712/73 Heading H1D Exposure apparatus for forming a colour cathode-ray tube (e.g. wide angle shadow mesh type) fluorescent screen (dots or stripes) comprises at least two correction lenses 14, 15, a shield member 20 with a perforation for exposing a selected area of the screen preferably placed between screen and lenses, and means for varying the relative angular position of the lenses and the shield member. The apparatus improves coincidence of the light beam path and the electron beam locus. Preferably each lens is wedge shaped with a curved surface or rectangular section with inclined surfaces divided by discontinuous border lines and preferably the angle between the two lenses is variable to compensate for varying misalignments of electron beam spots and phosphor dots. Lens design is discussed and composite lenses may be as in Figs. 5 to 8 and Fig. 10 (not shown). In Fig. 7, the rotation # of the assembly is varied to control the direction of correction, the relative angle #, and hence magnitude of the correction being constant. Accordingly, misalignments in any small areas of the screen may be corrected. In the discontinuous geometry of Fig. 10, the effect of thickness need not be considered, and the upper surface need not be inclined. As in Fig. 10A, the border lines of the two lenses are skewed which is equivalent to relative lens rotation. Perforation 25 may also be sector shaped, elliptical or polygonal (Figs. 9A, 9B, 9C, not shown). Vertical adjustment of lenses 14, 15 and shield 20 may improve correction. Increase in exposure time caused by shield 20 may be alleviated by a correction lens having both continuous and discontinuous curved surfaces. Prevention of colour shading in wide and narrow angle tubes with dot or stripe phosphors is disclosed.

Abstract: 1442420 Electrophonic musical instruments NIPPON GAKKI SEIZO KK 28 Dec 1973 [5 Jan 1973] 60094/73 Heading G5J In a computer organ, amplitude samples of two sets of Fourier components with a small frequency difference are calculated and combined to provide amplitude samples of a tone waveform exhibiting a celeste effect. When a key switch 12, Fig. 1, is actuated, a number R representing a corresponding frequency and a number # representing a small frequency difference are read from memories 17 and 18 respectively and applied at the start of a first computation period to adders 30 and 47. The contents of adder 30 is repetitively applied to adder 34 under the control of the first eight counts of a modulo-16 counter 21 to provide a count in adder 34 which determines the points at which a sinusoid table 36 is to be addressed to provide the amplitude samples of eight Fourier components of the true pitch tone. These samples, weighted by harmonic coefficients Cn from memory are fed to an accumulator 13. The eighth count of counter 21, slightly delayed, clears adder 34 and during counts 9-16, with gate 50 instead of 33 open, the Fourier components of the offset frequency are accumulated at 13. The sixteenth count of counter 21 gates the accumulated result to an output system 14, 16, 11. Simultaneously adder 34 is cleared and gates 29, 48 opened to add R and R+# to the contents of adders 30, 47 respectively (i.e. q is incremented by one) and the process is repeated to calculate the sample amplitude of the next sample point. In a modification, Fig. 3 (not shown) the true pitch set consists of fifteen Fourier components and the offset set has but one, and a logic circuit, Fig. 5 (not shown), is provided to inhibit celeste effect on certain notes. In another modification, Fig. 6 (not shown), the frequency of the clock is halved by processing the two sets of Fourier components in parallel. Neither set may be true pitch, one being above and the other below. More than two sets may be used.
