Title: Improvements in fluid energy grinding method and means
Inventor: STEPHANOFF NICHOLAS NICHOLAEVI
IPC: B02C19/06
Filed: 1967-01-16
Abstract: 1,141,552. Drying apparatus. FLUID ENERGY PROCESSING & EQUIPMENT CO. 16 Jan., 1967, No. 2212/67. Heading F4G. [Also in Divisions B1 and B2] To economize in high pressure gas supply to a jet mill 10, transport of the material around the mill is assisted by injection of gas, which may be at relatively low pressure, by subsidiary nozzles 44, 46, Fig. 1, or by recirculation of gas by impellers 312, 314, Fig. 7. The mill 10 comprises an impact chamber 12, compressedgas jets 36, feed devices 38, a first stack 14 connected with the impact chamber and with an arcuate classification section 16, which has outlet conduits 30, 32; a second stack 20 is connected with the classification section and with a recycle chamber 28, which is, in turn, connected with the inlet of the first stack 14. There is thus a circulatory flow path between the first stack, the classification section and the second stack along which the flow of gas and particles is accelerated by injection of gas by nozzles 44, 46. The fine pulverized material leaves via the conduits 30, 32. Gases used may be cool or hot air, steam, products of combustion, inert or reactive gases. Modification may include oppositely-rotating impellers 222, 224, Fig. 5, which not only induce high speed air circulation but may throw particles against each other, causing impact pulverization. The apparatus may be used for grinding coal, coke, metal, synthetic resins, ceramics, instant coffee, tea, cocoa, and for drying and mixing, coating, or facilitating chemical reactions by use of feed channels 48, 50.

Abstract: 1493087 Ellipsometer INTERNATIONAL BUSINESS MACHINES CORP 21 Jan 1976 [28 April 1975] 02251/76 Addition to 1419738 Heading G1A The apparatus of Specification 1419738 is modified by the replacement of a rotating analyzer by a fixed analyzer and a rotating quarter-wave retardation plate, which may be in the reflected or incident beam. The angular encoder is associated with the rotating quarter-wave plate. The arrangement permits unambiguous computation of #, the phase difference between the parallel and perpendicular components of the electric vector of the reflected beam. The angle # where tan # = R p /R s , Rp being the parallel and R s  the perpendicular component magnitudes, is also obtainable. A procedure is described, whereby for an imperfect retardation plate, corrected values of # and # are obtained.
Patent GB-613810-A (GB)
Title: Improvements in or relating to electrical musical instruments
IPC: G10H5/02
Filed: 1945-01-29
Abstract: 613,810. Electrical musical instruments. COMPTON ORGAN CO., Ltd., J., and BOURN, L. E. A. Jan. 29, 1945, No. 2279. [Class 88 (ii)] In an electrical musical instrument having frequency generators in which a single frequency serves as different harmonics for different notes and the generators are controlled by the keys through intermediate control devices, the means by which these devices are operated gives a suitable effect when several harmonics are required at the same time. The invention is described with reference to an instrument incorporating a thermionic valve as the control device, which is biassed beyond cut-off until the biassing potential is reduced by the depression of a key. Such a control means is described in Specification 613,414. Bus-bars 1a, Fig. 2, are connected through stop resistances 18x to changeover contacts 17x controlled by the stops. When a .stop is drawn, the moving tongues move over to their right-hand contacts and connect the bus-bars 1a to the positive terminal of a battery 20. They also remain connected to the negative terminal through the undrawn stop resistances and non-linear resistances 22. Their potentials therefore depend on which stops are drawn. The key contacts 2a, Fig. 1, connect the control grid of the valve 5 to the bus-bars when depressed or to earth when undepressed. The amplification of the valve 5 depends on its grid potential and this is determined by the potentiometer formed by the resistances of the depressed key on the one side and the non-linear resistance 10 on the other. If the frequency generator, connected to lead 4, has to sound on depression of more than one key, the potential of the grid is proportionately determined by the number of keys depressed. The non-linear resistance 10 and the low-pass filter 8, 14, 15 determine the build-up and decay of a note. The non-linear resistances 22, Fig. 2, reduce the rate of buildup of voltage on the bus-bars when several stops are drawn simultaneously. Specifications 403,444, 433,050, 453,846 and 613,414 also are referred to.

Abstract: 210,771. Miller, E. S. Feb. 1, 1923, [Convention date]. Condensers.-The rotatable plates 5 and spindle 6 of a variable condenser form a self-contained unit, which can be removed from the condenser as a whole without disturbing the fixed plates 3 or their supporting means. The spindle is formed with a conical bearing surface 6a which engages a similar surface in a bushing 15 carried by a plate 2 on which the rods 8 carrying the fixed plates 3 and their metal separating washers 7 are mounted. The spindle is secured in position in the bushing by a conical washer 16, a spring washer 26 and a nut 18 which screws on to a threaded portion 6b of the spindle. A counterweight 12, to balance the plates 5, is also mounted on the spindle. Some of the washers 7 may carry insulating stop washers 24 to limit the movement of the rotatable plates.

Title: A device for intermittently feeding substantially equal lengths of a web of material
IPC: B65H20/04
Filed: 1955-01-26
Abstract: 773,823. Feeding webs. VYZKUMNY USTAV' OBRABECICH STROJU A OBRABENI. Jan. 26, 1955 [March 19, 1954], No. 2361/55. Class 100(1) A device for feeding substantially of equal lengths of web material to a cutting device comprises a continuously rotating unwinding roller an intermittently rotating feed roller, which tends to feed the material faster than the unwinding roller, and a tensioning roller, interposed between the two rollers and spring pressed into engagement with the material, which causes a movement apart of the feed roller and a counter pressure roller in response to a predetermined deflection of the tensioning roller. As shown, a web 33, unwound from a supply roll, not shown by a continuously driven roller 5 co-operating with a pressure roller 10, passes over a tensioning roller 24 and between an intermittently driven roller 7 and a co-operating pressure roller 13. The roller 5 tends to feed the web faster than the roller 7, e.g., by making the roller 7 of slightly larger diameter than the roller 5. While the rollers 7, 13 are stationary the web 33 forms a loop around the roller 24 which is pressed against the web by a spring 25 attached to a lever 23 carying the roller 24. The roller 13 is freely rotatable on a shaft 11 slidable in grooves 12 of an upright 3 and is pressed towards the roller 7 by springs, not shown. When the loop around the pulley 24 is shortened a predetermined amount, a cam 27 on the lever 23 trips a tooth 28 on a lever 29 to rock the lever 29 into engagement with screws 32 on the spindle 11, such that the roller 13 is lifted to permit a small length of web to be drawn by the roller 24, rearwardly through the rollers 7, 13.
