Title: Improvements relating to means for controlling the thickness of strip or sheet materials
IPC: G01B5/06
Filed: 1949-02-28
Abstract: 670,976. Pneumatic gauging apparatus. LARMUTH, L. J., and LARMUTH, A. Jan. 25, 1950 [Feb. 28, 1949], No. 5354/49. Class 106 (ii). [Also in Group XXXV] Apparatus for controlling the thickness of materials such as thin strips or sheets comprises a nozzle supplied with compressed air at a substantially constant pressure, means for guiding the material past the nozzle in close proximity thereto or past a member having a part movable in accordance with the thickness of the material and in close proximity to the nozzle, and a pressure gauge, for measuring the pressure in the air system in the vicinity of the nozzle, fitted with electric contacts for actuating relay means for adjusting a machine forming the material so as to correct variations in its thickness. The strip g passes between rollers a and b and round a roller c where it is engaged by a roller h carried by a sprung lever. An adjustable screw in the other end of the lever controls the flow of air from a nozzle k, the pressure at the nozzle being indicated by a gauge p. Compressed air is supplied to the nozzle through regulator and restrictor valves m, o at a constant pressure indicated by a gauge n. The pointer of the pressure gauge is arranged to close, at upper and lower limits, adjustable electrical contacts associated with indicator lamps r and relay means p connected in the circuit of a motor f to cause the motor to be driven in one direction or the other when one or the other limit is reached. The motor drives a nut threaded on a shaft d which carries the bearing for the roller a. The spacings between the rollers are thus altered to restore the thickness of the strip to within the set tolerances. If the supply of strip ceases, a roller t engages the roller c and completes a relay circuit to open the motor circuit. The flow from the nozzle k may alternatively be directly controlled by the strip and several nozzles may be provided across the width of the strip.

Abstract: 525,236. Degreasing metal strip. BOOTH, W. E., AND IMPERIAL CHEMICAL INDUSTRTES, Ltd. Feb. 20, 1939, No. 5641. [Class 91] Metal strip is degreased by treatment with a volatile solvent, the vapour of which is heavier than air, in a closed apparatus containing means for maintaining a solvent vapour zone in the vessel and fitted with a tube extending vertically and fitted with cooling means through which the strip is withdrawn. In the preferred form of the invention the vertical exit tube is continued down into the vessel to a point below the solvent vapour level, and the entrance of the metal strip is effected through a vertical liquid cooled tube similar to the exit tube. Alternatively, the strip may be introduced and removed through the same tube. The strip in leaving the apparatus preferably passes rods or rollers near the point where the strip leaves the vapour zone, so that each surface of the strip makes contact with at least one such roller. In an example a closed vessel 1 with a sump 2 containing a heating element 3, is provided with two jacketed vertical tubes 6 and 8 for the entrance and exit of the metal strip. The tube 8 is extended into the vessel at 11 and both tubes are pivoted to facilitate the introduction of the strip. The strip 16 passes over a roller 10, enters the vessel through tube 6, passes over the second and third rollers 10, over the three staggered rods 12 and out over the fourth roller 10.

Patent GB-599669-A (GB)
Title: Improvements in or relating to the production of artificial filaments, foils and like shaped articles
IPC: D01F6/60
Filed: 1940-04-02
Abstract: Artificial filaments, threads, yarns, films, foils and like shaped articles are obtained by shaping a solution of a fibre- or film-forming polyamide in a phenolic solvent and setting it in an organic liquid medium which comprises a substantial proportion of a ketone of the formula R1.CO.R2, where R1 is the methyl radical or a substitution derivative thereof, and R2 is the methyl or ethyl radical or a substitution derivative thereof.  The polyamide may be obtained from a diamine and a dicarboxylic acid, or from an aminocarboxylic acid by selfcondensation.  The polymer may have a molecular weight of 4000-10,000 or more.  The phenolic solvent may be phenol, a xylenol, a cresol, a - or b -naphthol, resorcinol, a halogenated phenol, e.g. o- and p-chlorphenol, 2 : 4-dichlorphenol and 3-hydroxy-6-chlortoluene, an amino phenol, salicylic acid, o-hydroxy benzyl alcohol, or an oxy-di-phenyl.  The solution is in a fluid or highly plastic state while it is being shaped and if necessary it is heated.  The solution may be formed directly in the process of producing the polymer.  The ketone used for the setting operation may be acetone, methyl ethyl ketone, chloracetone, acetol, acetol methyl ether, or acetol acetate. Other non-solvents may be present in the setting medium, e.g. acetophenone, methyl alcohol, ethyl acetate, diethyl ether, petroleum ether, or toluene.  A small proportion of water may be present.  Solvents or swelling agents may be incorporated in the setting medium, e.g. formic, acetic, lactic, stearic, succinic, adipic or citric acid, or methyl formamide, acetamide, adipamide or p-toluene sulphonamide.  The shaping may be effected at 200 DEG  C. or more, but the setting medium is preferably maintained at a p  lower temperature, e.g. 15-30 DEG  C.  The spinning orifices are preferably arranged just above the setting medium in an atmosphere of inert gas such as nitrogen, hydrogen or carbon dioxide.  The filaments may be submitted to stretching during production.  They may be passed through one or more washing baths, e.g. of low boiling petroleum hydrocarbons or dried by passage through a hot gaseous medium before being wound up.  The filaments may be twisted or doubled to produce yarns, or they may be united by means of softening agents, heat or pressure to form bristles, straws and the like.  Bristles or straws may be obtained directly by extrusion.  Sheet materials may be used for wrapping purposes or as intermediate layers in safety glass manufacture.  In an example, a fibre-forming polyamide is prepared by refluxing hexamethylene diamine with adipic acid in xylenol, oxygen being excluded.  The resulting polymer is fed through narrow heated tubes and through spinning orifices situated just above a bath containing acetone.  The orifices are heated electrically. Specifications 529,510, 540,967 and 599,668 are referred to.
