Title: Improvements in pelletization of finely divided materials
IPC: B01J2/12
Filed: 1954-11-11
Abstract: 759,124. Agglomerating ores. CABOT, Inc., G. L. Nov. 11, 1954 [Jan. 12, 1954], No. 32622/54. Class 82(1). [Also in Group V] In making pellets from finely divided material, such as carbon black or metal oxides, by passing it down a rotating drum, means are provided within the drum to scoop up pellets at the outlet end and feed them back to the inlet end, so as to provide nuclei for pelletization. As shown, the material is introduced through a shoot 26 to a cylindrical drum 10 which is rotated about its longitudinal axis by rubber wheels 12, so that the material agglomerates as it travels through the drum. When the pellets near the outlet end have reached a certain depth they are picked up by a scoop 24 depending from an archimedean screw, comprising a continuous helix 22 within a cylinder 20 which carries them back to the inlet side of the drum for recycling. To prevent the material sticking to the wall of the drum 10, hammers may be attached to the outside or internal scrapers may be used. The pellets are expelled through a discharge tube 28. Specification 638,863 [Group III] is referred to.

Title: Video reproduction system for photographic and other images
IPC: H04N5/257
Filed: 1972-07-13
Abstract: 1405933 Video reproduction system GAF CORP 13 July 1972 [13 July 1971 3 July 1972] 32738/72 Heading H4F Photographic or other objects 17, Fig. 1, are reproduced on the C.R.T. screen 11 of a TV receiver 10 by periodically intensifying the cathode-ray beam during each line scan by electrical sampling pulses from a control circuit 20 (e.g. 400 sampling pulses per line) to produce corresponding sampling light pulses of constant high intensity which scan the object 17, the resultant light energy transmitted through or reflected from said object being converted by a photo-cell 16 into corresponding electrical pulse samples which are applied to modulate the C.R.T. via a high-pass filter 428 which selects the initial portion of each pulse sample, said selected portion being then stretched in a sample and hold unit (in the control circuit 20) to give a corresponding output video pulse of predetermined duration, the leading edge of said output pulse occurring after the trailing edge of the corresponding electrical sampling pulse. Each sampling light pulse (and thence the corresponding electrical pulse sample) has a finite decay time due to the persistence of the C.R.T. screen 11 and the high-pass filter 428 ensures that the amplitude of an output video pulse is not dependent on the decay portion of the corresponding electrical pulse sample. The sample and hold unit (details, Fig. 7, not shown) may be operated to give positive to positive or negative to positive reproduction. When the object to be displayed comprises photographic slides or film, the slide (or film) presentation unit 83, Fig. 4, may be mounted on top of the TV cabinet 81, the scanning light from the C.R.T. screen 82 being directed at the unit 83 by a mirror 90 mounted on a bracket 91 which is slidable so that the mirror 90 can be stored in a niche 93 when not in use. For colour reproduction using a conventional three-gun colour C.R.T., Fig. 8 (not shown), the guns are controlled to produce red, blue and green sampling light pulses sequentially, separate sample and hold units being provided for each colour channel and the single photo-cell being responsive to light of all wavelengths. For a monochrome system the duration of each output video pulse is at least six times greater than the duration of the corresponding electrical sampling pulse and for a colour system the corresponding ratio is about 5 : 1 for each colour channel.

Filed: 1921-12-10
Abstract: 174,047. Soc. Anon. des Ateliers d'Aviation L. BrÚguet. Jan. 14, 1921, [Convention date]. Motor power plant.-Re lates to means for coupling and uncoupling four internal combustion motors driving a common propeller shaft by means of sliding keys engaging recesses in a sleeve, and consists in a device for deter. mining the correct moment for coupling a previously uncoupled motor, having regard to the need for distributing the explosions uniformly over two revolutions of the shaft. There is one particular revolution in each two in which the key may properly engage its recess, and this movement is determined by sparking-points P secured on the half-speed cam-shafts of the motors and revolving within metal crowns Q which are connected to the ignition circuit of one of the motors so that the correct moment for coupling is indicated when the spark (which revolves with a speed corresponding to half the difference between the speeds of the motor to be coupled and of a motor already coupled) passes a predetermined reference mark R on the crown Q of the motor to be coupled. Other devices may be used for ascertaining the relative angular positions of the crank-shaft. Thus, a plate with a window may be fixed on each cam-shaft, and a lamp behind the plate may be lit every other revolution by another motor.

Patent GB-745500-A (GB)
Title: An improved method of applying dye-stuff in patterns
IPC: G03G17/04
Filed: 1953-12-03
Abstract: In a method of printing on a carrier, e.g. a sheet of paper the dye-stuff is atomized to form a mist of electrostatically charged particles which are directed on to the carrier by the action of an electrostatic field which is produced by an electrode charged to a potential opposite to that of <PICT:0745500/III/1> <PICT:0745500/III/2> the mist.  A local ionization being produced in the carrier so as to form conductive and insulating parts on said carrier.  In the form of Fig. 1 the dye-stuff is picked up by a charged roller 12 having a roughened surface and rotated in a container 13.  The electrostatic field between the roller 12 and the electrode 3 causes the dye-stuff to be drawn out into a cone 4 to form a mist 5 which migrates towards the electrode 3.  The paper 6 is separated from the electrode 3 by a matrix 14 of insulating material having inserts 15. 16 of a radio-active material on both sides in the desired pattern.  The radio-active material causes ionization of the air and paper in areas adjacent thereto so that the dye will be deposited exclusively at these areas. Alternatively the matrix may be conducting and coated on one side only with the radio-active material.  Ionization may also be produced by coating the matrix with a material which causes ionization when subjected to an electro magnetic radiation or with light which may be visible, ultra-violet or infra-red.  The matrix may be uniformly coated with this material and radiated in accordance with the desired pattern.  The radiation may be directed on the matrix through the electrode 3 which is made of a material both conductive and transparent to such radiation.  The electrode behind the paper sheet may be made of a substance transparent to such radiation.  An alternative form of matrix consists of an insulating sheet having embedded therein sharp edged grains, e.g. of graphite or small crystals disposed in the desired pattern.  The sharp edges cause local concentrations of the electrostatic field and attract the dye so that the pattern is reproduced on the paper.  The desired pattern or text may be reproduced from a matrix by repeatedly moving the paper to a fresh position and reproducing a small part of the design of the matrix at each operation.  Alternatively, in the form of Fig. 1 the matrix may be continuous and fed over the electrode 3 with the strip of paper 3. In the form of Fig. 3 the discharge electrode 18 has a series of projections 19.  A roller 20 is covered with a layer of graphite 21 in the desired pattern which is itself covered by a sheet 22 of insulating material.  As the roller rotates the dye is deposited in the desired pattern on the sheet 22 as described above and eventually transferred to the paper web 24 passing over an impression cylinder 23.  The other form of matrix 14, Fig. 1, may replace the graphite layer.
