Title: Method and apparatus for the production of carbon black
IPC: C09C1/50
Filed: 1968-08-07
Abstract: 1,221,443. Carbon black furnace. COLUMBIAN CARBON CO. 7 Aug., 1968 [9 Aug., 1967], No. 37767/68. Heading C1A. A furnace for the production of carbon black comprises a heat insulated, unobstructed, vertically elongated chamber 1 having means 9 for injecting a fluid, non-gaseous hydrocarbon axially upwardly into an unconfined localized region of the chamber, at least one primary duct 7 for directing hot combustion gases upwardly and in contact with the hydrocarbon, at least one secondary duct 8 for directing combustion gases upwardly around said localized region; independent supply means 11 and 19, 14 and 22 for the primary and secondary ducts provided with control means 12 and 20, 15 and 23, for regulating gas velocity, temperature and composition in various parts of the furnace, and means for removing effluent gases from the top of the furnace. A tertiary duct 10 may also be provided to impart a spiralling motion in the furnace atmosphere. A metered stream of hydrocarbon is injected at a constant rate, preferably as an atomized spray of liquid droplets using steam at 100 p.s.i.g. as the atomizing fluid, through nozzle 9 and combustion gases are passed through primary duct 7 in an amount sufficient to effect partial but incomplete conversion of the hydrocarbon to black in the localized region. A second portion of combustion gases is fed through secondary duct 8 at a different rate and mixes with the partially reacted hydrocarbon-combustion gas mixture in the chamber 1 and completes the conversion to black. The effluent gases are removed through conical top section 5 and breeching 6 and the black is separated by known means. It is preferable that air is preheated to 600-1500 F. prior to mixing with the fuel. The properties of the black produced may be varied by altering the relative velocities of the gas streams and the oxygen/fuel ratio in the combustion gases.

Abstract: 379,244. Lakes and rivers. PROPPER, E. J., 41, Sch³tzengasse, Biel, Switzerland. March 24, 1932, No. 8894. Convention date, March 28, 1931. [Class 68 (i).] Clean water is maintained at bathing places on the shores of rivers and lakes by means of one or more pumping units drawing water from a place where it is clean and delivering it adjacent the shore to replace the dirty water. In Fig. 1, the pumping units 6 with rotatable nozzles 12 are carried by floating platforms 10 and their suction pipes 4 extend to a pillar 3 in clean water ; the plant may be rotatable about the pillar.

Title: Injection moulding machine method for viscosity regulation therein and articles produced thereby
IPC: B29C45/76
Filed: 1976-09-16
Abstract: The screw ram (2) of the injection moulding machine is moved during the filling phase with controlled velocity by means of a hydraulic piston (6). The hydraulic pressure resulting in the cylinder space (10) is a measure for the viscosity of the melt. This actual value is compared with a setpoint value in a controller (13) and the deviation is used to correct the back pressure for the succeeding operating cycle. The viscosity of the melt can thereby be accurately and rapidly controlled, increasing the quality of the injection moulded parts. <IMAGE>

Title: Improvements relating to scanning circuits especially for colour television
Inventor: JAMES IVANHOE JOHN PENFOUND
IPC: H04N9/09
Filed: 1958-11-28
Abstract: 934,483. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 30, 1959 [Nov. 28, 1958], No. 38394/58. Class 40 (3). [Also in Group XL (c)] In a scanning arrangement for a television camera having a plurality of pick-up tubes, e.g. a colour or stereoscopic camera, the scanning waveform generator T1 is located within the camera and is connected to the scanning coils 1, 2, 3, of the tube through respective series combinations of variable inductances and resistances L1 and R1, L2 and R2, L3 and R3, which serve for adjusting the differential amplitude and form of the scanned rasters to produce accurate superimposition, the arrangement being characterized by the location of the inductances and resistances in a remote control unit which is connected to the camera by a cable 4. The inductances and resistances may be connected directly into the circuits between generator T1 and the scanning coils, Fig. 2 (not shown). In the preferred arrangement shown in Fig. 3, step-up transformers T2, T3, T4 each of turns ratio N are connected between the camera circuits and cable 4 and the inductances and resistances are increased in value N<SP>2</SP> times. The arrangement renders the inductance and resistance components of the cable negligible compared with the control elements and avoids any necessity for compensating for different lengths of cable. Reference is made to the use of a " quad " cable arranged to reduce the effects of cable capacitance, and the use of additional resistances and capacitances to remove or reduce undesired resonances.

Patent GB-359390-A (GB)
Title: Improvements in or relating to the manufacture of artificial films, foils and the like
IPC: A43B7/12
Filed: 1930-12-20
Abstract: Films of cellulose derivatives are obtained by depositing solutions thereof in volatile solvents upon a surface of synthetic resin.  The process is suitable for the production of cellulose acetate films or of films of other organic derivatives of cellulose.  The film forming surface may be obtained by coating a metal band, wheel, or the like with a solution of a synthetic resin, allowing the same to dry, and then subjecting the supporting medium having the resin coating thereon to a baking or other treatment whereby the resin coating is rendered insoluble and infusible.  The synthetic resin may belong to one of the following types: phenol-aldehyde, urea-aldehyde, diphenylol-propane-aldehyde, phenol-furfural, aryl sulphonamide-aldehyde.  If desired, the resin solution may be applied in a fairly thick layer and, while still plastic, the surface may be modified so as to give any desired design, or it may be treated to give a matt surface.  The layer is then treated to render it insoluble and infusible.  Preferably, the resin should not contain a softener or plastifier since such ingredients are liable to be attacked by the film forming solution.  For making discontinuous sheets, it is advantageous to employ a support consisting entirely of synthetic resin.  The films produced are free from any contamination with metal.
