Abstract: 313,085. Du Pont de Nemours & Co., E. I., (Assignees of Schwartz, G. L., and McCormick, F. H.). June 6, 1928, [Convention date]. Absorbent paper; pulp, preparation of.-Pulp for absorbent paper, suitable as a base for impregnating compositions such as contain resins, pyroxylin, rubber and the like, is obtained, by treating pulp with a swelling agent having the effect of kinking or curling the cellulose fibres and thereafter washing out the swelling agent. Caustic soda solutions are suitable but other caustic alkalies, sulphuric acid, zinc chloride, various thiocyanates, ferric chloride, and cuprammonium solutions may be used. In any treatment, the strength of the solution, the temperature and duration are such that oils, resins and other impurities which interfere with the wetting are dissolved or destroyed and then the temperature is lowered to produce a swelling action on the cellulose, curling but not dissolving it. An aqueous caustic soda solution may be used at normal room temperature, when it exerts a solvent action, and then cooled to effect the curling before the washing operation. The process is applicable to mechanical wood pulp, kraft, jute, soda pulp, rope, sulphite, and linen.

Title: A method of and apparatus for the drying of material in gaseous suspension
IPC: F26B3/08
Filed: 1951-07-17
Abstract: 687,460. Drying in suspension in gaseous currents. BUTTNER-WERKE AKT.-GES. July 17, 1951 [July 19, 1950], No. 16969/51. Class 34 (ii) A method of drying material capable of being kept in suspension in a gaseous medium combines drying the material in suspension in a chamber traversed by hot gases which gases after separation from the material are reheated and returned to the chamber, and stage-drying in which the material is conducted continuously through different individually heated zones, the drying medium being circulated substantially in the individual zones. In the lower part of a dryer housing 1 are blowers 2 and pipes 3 above which are trough-like grates 4 in which centrifuges 5, which assist the transport of the material are rotatable. Above the members 5 is the drying zone proper which is divided into adjacent zones 7 corresponding to the blowers and flaps 8 separate the material-air mixtures so that the material falls down again but the hot gases pass into a duct 9 whence after being heated on elements 10 the gases pass to the blower intakes. The material is caused to move from one zone to the next by baffles or by vanes 12 on a common shaft 11 which drives the centrifuges 5. Material is introduced at 13 and falls on to vanes 12 which convey it to grate 4 where under the action of the device 5 and the hot gases it is brought into a state of suspension and progresses from zone to zone to be discharged dry at 14. The stream of hot gases is introduced at the discharge end of the apparatus so that after having passed through a zone and having been separated and reheated it is partly drawn in by the same blower and part of it passes to the next blower the last blower exhausting the gases to atmosphere.

Abstract: 901,954. Tumbler driers. GENERAL MOTORS CORPORATION. May 10, 1961 [May 19, 1960], No. 16990/61. Class 34 (2). A clothes drier comprises an air blower, an air heater, a timer for controlling air flow past the clothes and heating of that air flow and a device responsive to relative humidity of air leaving the clothes arranged to stop the timer when the relative humidity is greater than a predetermined value. A tumbler drier drum 20, Fig. 1, has a perforated rear wall 22 for the passage therethrough of air heated by an electric heater 40 and circulated by a fan 36 in an exhaust duct 29 driven by the drier motor 38, and a humidity sensing element 46 in the duct is arranged to control a timer motor 66 by a solenoid 49, Fig. 3, and amplifier 50 through a switch 84. The timer 62 in normal operation controls the heater and a damper 34 in the duct 29 to provide high heat with high air flow, followed by low heat with low air flow, followed by high air flow without flow, but the element 46 stops the timer motor 46 when the relative humidity of the air leaving the drum is greater than a predetermined value. The control circuit for the drier comprises a thermoresponsive switch 54 placed near the heater 40 to de-energize the heater if the temperature in the casing exceeds 240 F.; a centrifugal switch 56 which is closed when the motor 38 is in operation, prevents energization of the heater if the motor fails to start, and a thermo-responsive switch 58 breaks the circuit if the amplifier 50 or element 46 fail or if the heater remains unenergized. The timer 62 comprises a shaft 64 controlled manually by a knob 76 for initiating the drying operation and carrying cams 68, 72 operating switches 70, 74 respectively, which move a series of contacts 82, 86, 88 and contact fixed contacts 78, 80 respectively. The fixed contacts 78, 80 are connected to side L 2  and neutral line N of the power supply respectively. The switch 70 is connected to side L 1  of the power supply and closes on the spring contact 82 which is connected by a lead 106 to the amplifier 50, by leads 107, 110 to the switch 84 controlling the timer motor 66 and by leads 107 to the drier motor 38. Further movement of the switch 70 causes the contact 82 to touch the contact 86 which is connected to the thermoresponsive switch 54 which in turn is connected to a switch 94 connected to one end of the heater 40 and the other end of the heater is connected to the thermo-responsive switch 58 movable between a contact 59 to the switch 74 and a contact 61 to the timer motor 66. Further movement of the switch 70 causes the contact 86 to touch the contact 88 which is connected through a solenoid 48 for controlling the damper 34 and so reduce air flow through the duct and drum.

Title: Production of tinplate
Inventor: SIMS RAYMOND BERNARD
IPC: C21D8/02
Filed: 1962-05-03
Abstract: A process for producing thin metal coated steel strip comprises cold reducing hot rolled strip in two stages giving at least 70% and then 10% reductions, continuously annealing the strip, and giving it a metallic coating.  For producing very thin tin plate, hot rolled strip is reduced in a 4 or 5 stand tandem mill and then in a 2 or 3 stand tandem mill. The strip is cleaned and passed through a continuous annealing line employing a lead-bismuth or other high temperature bath at a temperature above A3 point to give the strip a hardness of greater than 67R. 30T on the Rockwell Scale.  The strip is rapidly cooled to 250 DEG C. and coiled.  The cooled strip is then passed through a temper mill, to give at least 10% reduction, and finally to a tinning line.  For producing conventional tinplate of 0.0077 inch and above the 2nd cold rolling step is missed out and the annealing produces a hardness of 60R. 30T. Finally the strip is over aged, given a temper pass, and tinned.
