Title: Ferrofluid display device
IPC: G02F1/167
Filed: 1976-01-13
Abstract: 1535273 Matrix displays INTERNATIONAL BUSINESS MACHINES CORP 13 Jan 1976 [27 Jan 1975] 01252/76 Heading G5C A matrix display panel comprises two immiscible liquids with different optical properties and with one containing magnetic particles, e.g. Fe 3 O 4 ; droplets of one of the fluid phases may be emitted near one end of each of an array of display columns 16 and are translated along these columns by a rotating magnetic field. The structure is formed between parallel glass plates, possibly with a perforated mask against one of the plates, and a rotating platelike permanent magnet 40 lying behind the rear plate, or for high speed its electromagnetic equivalent, causes fluid of one phase to progress generator G (also see Fig. 3A, not shown) formed from permalloy teeth, from where droplets enter the shift register column struetures 16 if the magnetic state of respective switching coil 45 does not deflect the droplets direct to the recirculator teeth 10. The droplets finally emerge at R after step-by-step progress through columns 16, and move with successive field rotations back to reservoir V, some being retained in local reservoirs round discs 110. Magnetic fluid, with surfactant additive possibly in an aqueous base, in, e.g., a hydrocarbon or halogenated hydrocarbon second liquid, will appear as opaque droplets blocking successive apertures along the columns in the mask to form a display, the missing droplets allowing illumination by, e.g., an electroluminescent source behind the rear plate or by a lamp inside a bowl-shaped rotating magnet. Alternatively clear droplets of the non-magnetic phase can be translated in the opposite direction through a continuous opaque magnetic phase, no mask then being required. For vertical operation the two fluids should match in density; for horizontal working preferably a third heavier transparent phase immiscible with the other two should be included, the droplet phase being intermediate in density, running in the second phase on a layer of the additional phase as a bearing. The magnetic elements may be wettable by the magnetic phase to assist storage of data on switch-off, while ribs 47, 65, 90, &c. and gasket 170 should be of inert material not wetted by the droplet fluid. The droplet generator G may alternatively be a pump or may depend on capillary forces. If either the droplet fluid or the continuous medium is electrically conducting, the presence of a droplet at any site may be detected electrically in addition to visual indication.

Title: Improvements in or relating to intermittent movements
IPC: F16H27/04
Filed: 1949-01-18
Abstract: 663,880. Intermittent toothed gearing. GENERAL PRECISION LABORATORY, Inc. Jan. 18, 1949 [Jan. 28, 1948], No. 1424/49. Class 80 (i) [Also in Group XX] In mechanism of the kind in which a gear wheel, driving a sprocket, is rotated intermittently by a continuously rotating cam disc having a main portion perpendicular to its axis of rotation and an offset peripheral portion which advances the gear wheel by one tooth at each revolution of the cam, resilient or frictional means is provided to maintain only one face of a tooth of the gear wheel in contact with the cam. The Figures show two perpendicular elevations each partly in section of one embodiment applied to kinematograph apparatus. The sprocket 31 is carried on a shaft 28 secured to or integral with a wheel 27 with teeth 29. One of the teeth normally rests on the face of a disc 23 at the end of a continuously driven shaft 12. A portion 26, struck out of the plane of the disc, however, feeds one tooth for each revolution of the shaft 12. A spring 36 is secured at one end to a pin 38 on the shaft 28 and at the other to a pin 39 carried on a gear wheel 41 rotatable round the shaft 28. This gear wheel meshes with a gearwheel 47 on a shaft 48 driven by worm and worm wheel 22, 49 from the shaft 12. The ratio of this train is chosen to secure a constant average tension in the spring 36 and maintain the operative tooth 29 secure in engagement with the disc 23. The shaft 12 rotates in a bush '16, axial movement being prevented by the hub 19 of the worm 22 and a collar 51. The bush is screw threaded at 14 into a fixed member 13 and by rotating the bush, through a flexible shaft 58 and gearing 55, 56, an axial movement is produced which rotates the gear 27 to provide an additional movement to the sprocket to frame the film in the projection aperture. In another embodiment the spring 36 and associated gearing are dispensed with and the engagement of the operative tooth 29 with the disc 23 is secured by a frictional device which retards the shaft 28.

Title: Method of cleaning a centrifuge
IPC: B04B1/20
Filed: 1975-01-15
Abstract: 1462004 Cleaning centrifuges PENNWALT CORP 15 Jan 1975 [15 Feb 1974] 1780/75 Heading B2P. In a method of cleaning a screw-conveyor type centrifuge after use, the bowl of the centrifuge is partially filled with cleaning liquid and is rotated about a horizontal axis at a speed below that at which the centrifugal force imposed upon the cleaning liquid by rotation equals the gravitational force acting on the cleaning liquid. The bowl is first emptied of process materials by flushing with water. The cleaning liquid may 'be of the caustic type. As the bowl rotates, the cleaning liquid will not spin with the bowl in a complete circle, but rather it will "peel off" and fall back into the bottom of the bowl, thereby creating turbulence which is effective for cleaning action. Cleaning may be improved by operating the screw conveyor at maximum speed differential relative to the bowl and by rotating the bowl alternatelv in opposite directions. An acidic flushing liquid may be introduced into the bowl to neutralize the cleaning liquid before the bowl is finally flushed with water. Additional cleaning liquid may be fed into the bowl as it rotates so that used cleaning liquid is discharged with solids scoured from inside the bowl.

Title: Improved method of separating actin from muscle material
Inventor: SZENT-GYORGYI ALBERT EMERICH
IPC: A61K38/00
Filed: 1954-01-21
Abstract: A method of separating actin from an intimate mixture of polymerized actin and myosin, e.g. solid actomyosin, raw muscle from which part of the myosin may have been removed by potassium chloride-phosphate solution, comprises reversibly depolymerizing the actin with an aqueous solution containing 10-4 to 10-3 mol. adenosine triphosphate and 0.5 to 0.8 mol. potassium or sodium iodide or thiocyanate at a temperature below 25 DEG  C. and preferably from 0 DEG  to 5 DEG  C. If the iodide is used, a minute portion of thiocyanate should be present, and if the thiocyanate is used, the presence of a minute portion of potassium chloride is desirable.  A supernatant phase is obtained to which a water-soluble precipitating agent capable of selectively precipitating the myosin without denaturing the depolymerized actin, e.g. ethyl or methyl alcohol, acetone, may be added, or the supernatent phase may be diluted with water to precipitate the repolymerized actin as actomyosin which is redissolved in aqueous potassium iodide solution containing a minute portion of adenosine triphosphate and the myosin is precipitated from the solution as above.  Actin may be recovered from the liquid phase by dialysis, e.g. against a phosphate buffer solution, or by isoelectric precipitation in the absence of salts.  Raw muscle tissue, when used, contains sufficient adenosine triphosphate for the depolymerization and it will be unnecessary to add any additional triphosphate.  Complete polymerization of the actin can be induced by addition of a small amount of potassium chloride.
