Abstract: 100,400. Projectophone Co., (Assignees of Madaler, F. von). May 1, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Ribbon and tape records; duplicating; records, combined phonograph and kinematograph; mandrels.-A record is produced on the edge of a ribbon, for example a kinematograph film, by moving the ribbon edge over the sound-groove of a heated cylindrical master record rotatably mounted. The apparatus is shown in elevation in Fig. 1, in plan in Fig. 2, and in vertical section in Fig. 4. The master record 10 is rotatably mounted in a fork 23, which is pivoted on centres 25 to an arm 30, and is balanced by an adjustable weight 28. The arm 30 is mounted on a vertical pivot in a bracket 34, which may be fed transversely by a screw 38 and disconnectible nut. The ribbon 40 is fed from a loose reel 41 to a driven reel 43 by a sprocket 45 geared to a spring motor 47, which also drives the screw 38 through a shaft 54 and bevel-gearing. The reel 43 is driven by a belt 51 which allows slipping. The ribbon 40 is gripped between a fixed back-plate 59 and a rectangular frame 62 pressed by a spring arm 64. The backplate 59 has a lip on its upper edge which prevents the ribbon and the frame 62 from rising, and both plates are recessed immediately beneath the master record 10. The master record is heated by a perforated gas tube 68 or by other means. When the motor 47 is started, the edge of the ribbon engages the soundgroove, and the record 10 is rotated, the heat softening the material of the ribbon and allowing it to be impressed with the record undulations. Two ribbons may be impressed simultaneously by arranging a second set of reels, rotating in the opposite direction, above the master record. In order to obtain the master record, the sound may first be recorded on the interior of a cylindrical blank 10 carried within a cup 11, which is rotated by a belt 12 and fed forward by a screw 13. The recording-tool has a concave point. The metallic master record is obtained from the cylinder 10 by electro-deposition.

Patent GB-734044-A (GB)
Title: Machine for dyeing and washing fabric yarn and other fibrous material in indefinite lengths
IPC: D06B3/26
Filed: 1953-03-04
Abstract: A machine for the wet treatment of a fabric in rope form in indefinite length in which the material traverses at least one loop, the lower portion of which is submerged in a liquid bath comprises a rail over which the fabric passes, the rail having ribs which are such that the fabric is thrown against the reel between the ribs whilst <PICT:0734044/IV (c)/1> <PICT:0734044/IV (c)/2> the reel is rotating during the treatment.  Fig. 1 shows a machine for carrying out two liquid treatment processes, for example dyeing and washing of a fabric T in rope form of indefinite length.  The fabric passes over a feed cylinder 14 through a liquid spray funnel 15 into one end of a vat 4 containing treatment liquid and is then fed upwards to a rotating ribbed drum 1 and is passed over the drum in successive loops over its entire length as shown in Fig. 2.  The fabric then enters a counter shoot 16 and passes into a second vat 5 and is passed in successive loops over a drum 2 which rotates in a direction opposite to that of drum 1.  The fabric may then either be fed back into the first vat to form a closed cycle or may be drawn over a cylinder 18 and passed to further machines.  Oscillating combs 19 guide the fabric over drums 1 and 2 and are provided with means which automatically stop the machine if the fabric becomes accumulated or entangled so that rates of feed as high as 180 metres/minute may be reached.  Drums 1 and 2 have ribs 3 which cause the fabric to be arranged in polygonal turns so that it is thrown against the wall of the drum and is deeply penetrated by the treatment liquid. The level of liquid in either vat is adjusted by means of a rotatable tube having a slot along its length, Fig. 3 (not shown), which is located in a tubular section of each vat so that on rotation of the inner tube liquid from the vat passes into it and thus into a discharge conduit.  The quantity of liquid in either vat may be increased by supplying liquid from the perforated tubes 13a, 13b and the vats may be heated by heating means 10.

Patent GB-449274-A (GB)
Title: Improvements in the manufacture and production of hydrocarbons of high boiling point
IPC: C07C1/06
Filed: 1935-02-27
Abstract: Hydrocarbons of higher molecular weight than benzine, such as paraffin waxes and lubricating oils, are obtained by the catalytic reaction of carbon monoxide with hydrogen at below 375 DEG  C. and above 20 atm. pressure in a hydrocarbon medium which remains liquid under the reaction conditions.  The catalyst may be dispersed in the hydrocarbon medium or may be rigidly mounted, e.g. in tubes or in gauze pockets on a stirring device. Preferably, the hydrocarbon medium is continuously removed from the reaction vessel and returned thereto, if desired with intermediate filtration or other purification and if desired with intermediate regeneration of the filtered catalyst, e.g. by grinding.  The reaction products may be separated from the hydrocarbon medium by distillation or by extraction with sulphur dioxide or other solvent.  Specified catalysts are the metals of the sixth periodic group and of the iron group, and titanium, zinc, copper, vanadium, aluminium and manganese; oxides or other compounds of these metals, including the sulphides of the heavy metals, may also be used, as well as mixtures of the metals or their compounds, e.g. mixtures comprising (a) iron, copper and manganese, or (b) chromium, zinc and manganese, or (c) iron, copper and zinc.  The catalysts may be activated by treatment with an alkali, a halogen or a halogen hydride, or by addition of a rare earth or silver or a compound thereof.  In an example, a mixture of carbon monoxide with a large excess of hydrogen is heated to 250 DEG C. under 50 atm. pressure with anthracene oil in which a catalyst comprising zinc oxide, magnesia and iron is suspended; a mixture of hydrocarbons, mainly paraffin wax and lubricating oil, is recovered from the product by distilling off the anthracene oil or by extraction with liquid sulphur dioxide. Specification 328,586, [Class 2 (iii)], is referred to.

Abstract: 753,153. Continuous metal-heating furnaces. WISTRA OFENBAUGES. March 3, 1954 [March 3, 1953], No. 6280/54. Classes 51(1) and 51(2). In a continuous metal-heating furnace of the pusher type divided into a preheating zone 3, a main heating zone 4, and an equalising zone 5, the latter is heated by burners 8 disposed in the direction of travel of the billets 1 and supplied with preheated fuel gas and with a highly preheated mixture of air and waste gases. The concave end wall of the equalising chamber causes the hot gases to double back over the billets, after which they traverse in turn, a duct 12, a brick recuperator 13, a duct 15 and a recuperator 9. A pipe 10 feeds hot fuel gas from the recuperator 9 to the burners 8, and also to main burners 7 disposed oppositely to the direction of travel of the billets. Hot air from the recuperator 9 passes through a branched pipe 11, partly to the main burners 7, and partly, after admixture with hot waste gases diverted from the duct 15 under control of a valve 16, to a fan 14, which forces the air/waste gases mixture through the recuperator 13 and a duct 19 to the burners 8. Billets in the preheating zone 3 are heated from above by waste gases from the main heating zone 4, and from below by burners 6 supplied with cold fuel gas and air. In a modification, Fig. 2 (not shown), the recuperator 13 is omitted and waste gases are caused to recirculate within the equalizing chamber by forming the burners 8 as Venturi injectors. A further modification, Fig. 3 (not shown), also omits the recuperator 13, and waste gases drawn off the preheating zone are supplied by a fan to the burners 8.
