Patent ES-274451-A1 (ES)
Title: Method of baking plaster at low temperatures
IPC: C04B11/02
Filed: 1962-02-08
Abstract: <PICT:0945107/C1/1> Plaster is produced by placing gypsum in a vessel equipped with heating surfaces wherein the gypsum is first heated to about 105 DEG C. when dehydration begins, and is then maintained under agitation by steam pulses, the velocity of which is at least as high as the fluidizing velocity of the mass being treated, at 110-135 DEG C. until converted almost completely into a calcium sulphate semi-hydrate when the temperature is increased to 160-180 DEG C. The steam pulses last between 0.01 and 5.0 seconds and have a frequency of 15-2000/hour but which may be increased at the beginning and end of the treatment. During the final phase of the treatment the agitating steam may be wholly or partly replaced by air. The steam evolved by the dehydration of the gypsum may be recycled to provide further agitating pulses. The Figure shows gypsum fed from hopper 2 into passageway 1 which is divided by weirs 18 into a series of zones, each of which has a heating element 5. Agitating steam is fed to each zone through inlet pipes 9 and is controlled via valves 10 by timers 17. The steam after agitating is removed at outlet 14 when it may be either discharged or recycled.

Patent ES-349788-A1 (ES)
Title: Method for processing synthetic thermoplastics into shaped structures
IPC: B29C48/395
Filed: 1968-01-26
Abstract: In the extrusion of thermoplastics rods, the process is rendered intermittent by the provision of a draw off device which applies an increasing longitudinal pull on the extrude in a direction away from cooled die 3 until material which has solidified therein slips through the die, the pull then immediately decreasing to a minimum valve, possibly zero, prior to a repeat of the cycle, see Fig. 2 (not reproduced). As shown, the draw-off device comprises a frame 14 on which are mounted driven rollers 5-10, with rollers 5, 7 and 9 being urged towards rollers 6, 8 and 10 respectively by compreased-air cylinders 11-13. Frame 14 is mounted on resilient blocks 15, 16 to allow longitudinal displacement and is connected to the extruder barrel via rods 17-20 and an intermediate coupling comprising compression springs 24, 26. In operation, at the start of a cycle, rollers 5-10 are rotated to produce a movement of frame 14 towards die 3. This movement causes compression of springs 24, 26 and hence an increase on the pull on extrudate 4. At a certain value of pull the extrudate slips through die 3, frame 14 moves to the right and springs 24, 26 are relieved. Preferably the rods formed are greater than 30 mm. in diameter and it is stated that molten material from the heated barrel of the extruder passes to cooled die 3 where an increasingly thick skin is formed, the internal pressure of molten material on the skin preventing movement through the die. Preferably the amount of slippage which occurs is between 1 and 20 mm. at a time. The thermoplastics material preferably has a modulus of elasticity greater than 10,000 kg./cm.2 at 20 C. and the process is particularly intended for the extrusion of thermoplastics having a basis of polyethylene terephthalate, e.g. mixtures thereof with polypropylene or poly-4- methylpentene, and the mixtures described in specification 1,196,290. Other thermoplastics mentioned are polyphenylene oxide, polyacetal polycarbonate and ABS polymers.
Patent ES-357904-A1 (ES)
Title: Reduction of turn-on delay in liquid crystal cell
IPC: G02F1/137
Filed: 1968-09-06
Abstract: To reduce the time required for a nematic liquid crystal cell to change from its transparent state to its light scattering state in response to repetitive voltage pulses of relatively short duration, a number of such pulses being required to cause the liquid crystal to scatter light to an extent which is a function of the amplitude of the pulses, the internal resistance of the cell is increased prior to the application of the repetitive pulses. To increase the internal resistance of the cell the number of free current carriers present in the liquid crystal is reduced by applying either a continuous direct voltage bias (Figs. 8 and 9, not shown) or a continuing train of voltage pulses (Figs. 10-12, not shown) to the cell at a level lower than the voltage threshold for dynamic scattering of the cell. By increasing the internal resistance it is found that the number of excitation pulses necessary to effect a substantial amount of light scattering is reduced, i.e. the " turn-on " time for the cell is reduced. In addition, the cell exhibits a larger scattering effect and is thus brighter. The liquid crystal cells may be arranged in a matrix to form a television type display, and in every frame interval a row of cells is simultaneously " addressed," i.e. have their internal resistances increased, while pulses having amplitudes corresponding to the video information of respective elements of the row are applied to the cells.

Filed: 1970-07-02
Abstract: Registering.-Sheets are fed as required either from a feed tray 34, Fig. 1, between guides 86, 87, Fig. 4, or from a secondary feed tray 35 between guides 91, 92 and thence by feed rollers 96, 97 and between guides 93, 94, 95, to a registering device 22 and thence to the transfer station D of a xerographic reproducing apparatus 10, the guide 95 being movable to allow access to the feed path. The registering device comprises register stop rollers 60, Figs. 2 and 4, each having a stop face 67 and initially stationary, so that a sheet is fed against the faces 67 and continued to be fed so as to be held against the faces, the guides allowing buckling of the sheet. Pressure rollers 69 are then raised against the rollers 60 under the control of a cam 122, and a cam 120 causes the rollers 60 to rotate with an acceleration which feeds the sheet towards the station D. When maximum velocity is reached, pressure rollers 68 are raised under the control of a cam 122 against rollers 70 continuously driven at said velocity, so that the sheet is fed by both rollers 60 and 70. The rollers 69 are then lowered, leaving the sheet to be fed by the rollers 70 only, and the rollers 60 are slowed and stopped and then returned to their initial stop position ready for the next sheet.
