Title: Heat treatment apparatus
Inventor: STRAND ELMER ERIC
IPC: B01J8/08
Filed: 1969-01-31
Abstract: 1,259,961. Rotary annular furnaces; rotary drying apparatus. E. E. STRAND. 31 Jan., 1969 [8 Feb., 1968], No. 5446/69. Headings F4B and F4G.  Heat treatment apparatus 20 for use in calcining, roasting, or drying of materials incorporates a rotatable perforate screen 41 fed with material to be treated from a hopper 21. The material is heated by a fixed impermeable membrane 58 made of ceramic material which radiates heat received from surface combustion heaters 42. The membrane 58 forms a sealing member preventing heater combustion gases from contacting the material being treated. Oxygen or air, if required, may be introduced into the treatment zone defined between the screen 41 and membrane 58 through a conduit 68. Products resulting from the heating drop down through the screen and are collected in a conical vessel 26. Residue is swept off the screen by a brush 46 and is removed through an air lock located in a discharge shoot 23. Gases released from the heat treated material are withdrawn through a pipe 104, any liquids formed being removed through conduits 106,107. Each surface combustion heater 42 is provided with a hollow frame (see Figs. 8 and 9, not shown) through which coolant water is circulated. Spaced transverse triangular member 75, made of stainless steel, form reflectors and are located above a burner screen 78 of ceramic coated wire. A reverberator screen 88 is interposed between the screen 78 and the impermeable member 58. Combustion gases from the heaters 42 exit through ducts 87 into a central stack 38. An annular ring 25 through which coolant water is circulated insulates the perforate screen 41 from the collection vessel 26.

Title: Improvements in carbon black manufacture
IPC: C09C1/50
Filed: 1960-02-16
Abstract: A gas-atomized spray of liquid hydrocarbon is injected vertically and coaxially into an elongated, heat-insulated furnace chamber located to a temperature in excess of the decomposition temperature of the hydrocarbon by passing hot gaseous products of combustion upwardly through the chamber adjacent the periphery thereof and so removed from the spray as to avoid infiltration there into of any unburned oxygen present therein, and the hydrocarbon being thereby decomposed into carbon black in gaseous suspension before it is passed from the furnace chamber to separating means.  The liquid hydrocarbon may be sprayed in an upward or downward vertical direction.  Specified atomizing gases are steam and a mixture of steam and air.  Liquid hydrocarbons mentioned are aromatic petroleum residues and coal tar. Hot gaseous products of combustion may be produced in situ, air entering the chamber tangentially through a conduit, or they may be admitted to the chamber from an external source.  Comparative examples are given.  Specification 763,159 is referred to.
Patent GB-1163063-A (GB)
Title: Improvements in Pulsed Light Photometric Method and Apparatus.
IPC: G01J1/16
Filed: 1967-02-06
Abstract: 1,163,063. Photo-electric sample analysis. KOLLMORGEN CORP. Feb. 6, 1967 [July 18, 1966], No.5527/67. Heading G1A. [Also in Division H4] In an arrangement in which a sample 16, Fig. 1, is investigated by light from a pulsating source 10, output noise arising from source pulse-amplitude variations is suppressed by developing a signal from the light pulses and applying it to vary the output signal from the photo-sensor either as developed or subsequently, the lamp may be a pulsed xenon arc and the light is focused to fall on the surface of a sample 16 or standard 15, according to the position of a rotating mirror M3, by an optical system comprising lenses L1, L2, and apertures A1, A2, 8% of the light energy being deflected by a partly silvered mirror M2 on to a pair of source monitoring transducers 20, 21 to develop the noise suppression signal. The light reflected or transmitted by the sample according to the nature of the test is applied alternately with that reflected or transmitted by the standard, to a photo-multiplier 25. The rotation of mirror M3 activates a switch 13 to appropriately pulse the source, and a switch 27 to direct the outputs representative of the standard and sample to appropriate circuits, each including a "boxcar" and an amplifier A1, A2 for comparison. Long term stabilization of the system is provided by a feedback on which the D.C. high voltage supply 40 to the photo-multiplier is adjustably controlled by the pulse height of the signal related to the standard, a tapped off portion of the signal across a potentiometer 36 being compared with a reference voltage in a comparator 41. The source monitoring photosensors may be photo-conductive, or photo-voltaic, and may control the potential on a further dynode of the photo-multiplier, may be connected in series or in shunt across the main sensor load circuit, or may control the gain of an amplifierin the main output path. More than one monitoring photo-sensor may be used in these circuits, and the sensors may comprise double-junction silicon diodes. In an arrangement carrying out a spectral test and using a plurality of photo-sensors all the sensor outputs may be controlled by a single monitoring sensor. In an amplifier gain control circuit, Fig. 6, the main and monitoring inputs are applied alternately, and the latter sets the impedance of an FET to determine the amount of feedback which is then maintained by a capacitor C1 whilst switches S1 S2 are in the "a" position. The switches may be solid state devices.
Patent GB-849541-A (GB)
Title: Preparation of unsaturated cyclic urea derivatives
IPC: C07D233/32
Filed: 1957-02-19
Abstract: Cyclic ureas of the formula: <FORM:0849541/IV(b)/1> are prepared by reacting ethylene-urea or trimethylene-urea with an aldehyde RR1CH, CHO, R being H, phenyl, tolyl, benzyl, cyclohexyl or C1-C8 alkyl, R1 being H or C1-C4 alkyl, and n being 1 or 2.  The reaction may be carried out with or without a solvent such as water or a C1-C4 alcohol.  It is preferable to work at a temperature of 15 DEG -220 DEG  C. and to add an acid to bring the pH to 1-6,5.  The first stage of the reaction probably produces an N-(a -hydroxy-alkyl) compound which self-condenses to give a polymer.  On heating to 185 DEG -300 DEG  C. the polymer decomposes and the N-vinyl compound distils over; this stage is aided by the addition of alkali to bring the pH to 7-8. When a C1-C4 alcohol (e.g. methanol or isopropanol) is used as solvent the aldehyde initially forms a hemiacetal which reacts with the cyclic urea to give the N-(a -alkoxyalkyl) and N: N1-bis-(a -alkoxy-alkyl) compounds as well as the polymer. The alkoxy compounds can be distilled off separately before pyrolysis of the polymer, but if an alkali alkoxide is added they too yield the desired vinyl compound on heating and then need not be separated.  In examples, the aldehydes used are acetaldehyde, propionalde hyde, capric aldehyde, phenylacetaldehyde, cyclohexyl-acetaldehyde and hydrocinnamaldehyde.
