Title: Apparatus for artificial respiration and other respiratory purposes
IPC: A61M16/00
Filed: 1945-07-06
Abstract: 595,658. Artificial respiration and respiratory apparatus. ERICKSON, C, N. July 6, 1945, No. 17321. [Class 81 (ii)] In artificial respiration apparatus comprising a mask, a source of gas under pressure and gas control mechanism, the latter includes a housing 2 having a port 63 connected to the mask and a conduit 14 traversing the housing with a fitting 16 at one end connected to the gas source and a discharge port 32 at the other. A venturi nozzle 22 and tube 23 are screwed into conduit 14, whereby with valve member 33 in the open position shown in Fig. 3, air is withdrawn from the interior of the housing and so of the lungs through a port (not shown) in the part of the conduit surrounding the nozzle. The air and gas escape through apertures 21 in a felt-lined silencer 19. A diaphragm 6 is clamped between a flange 8 and ring 9 held by section 1a of the housing when screwed into position, and its upper side is open to the atmosphere through vents 11. When the pressure in the housing is reduced to a certain limit, the diaphragm is bowed inwards, thereby closing valve 33 through the action of arms 34 (straddling conduit 14) and toggle device 36, 39. The gas thereupon passes from the nozzle and port referred to, to the lungs. When the pressure reaches a certain limit, diaphragm 6 is pressed outwardly and the cycle repeated. A vacuum relief valve (not shown) is provided on the casing adapted to open when the vacuum exceeds, say, 4 ounces/sq. in., and also an adjustable pressure relief valve. At one extreme, it is set to open when the pressure exceeds, say, 4 ounces/sq. in. ; at the other when the pressure is less than that required to move diaphragm 6, whereby the device may be used as an oxygen-supply apparatus as in airplanes. The mark which is preferably made of transparent material, may be mounted directly in port 63, or (Fig. 5) there may be interposed a tube 70 serving as a handle and provided with a valve 75 which may be operated to open vent 76 should the patient vomit. The mask may alternatively be mounted axially at the end of the tube. In another form, a tubular handle is disposed adjacent gas control valve G.

Title: Improved process for the low temperature distillation of coal and apparatus therefor
IPC: C10B1/04
Filed: 1925-07-06
Abstract: 259,295. Travers, M. W., and Clark, F. W. July 6, 1925. Coking processes.-In distilling coal and like carbonaceous materials superheated steam at about 650‹ C. is passed through the charge and the dirty steam after use is sprayed with hot water and its remaining heat used in the generation of clean steam for use in the process. Steam is passed from a pipe 16 into one of two superheaters 2 where it is heated to about 650‹ C. and passes by a pipe 1<1> into a retort 1, producer gas and air passing through valves 2<1> into and being burned in the other superheater. The steam charged with volatiles from the retort. 1 passes by a pipe 10 into a scrubber 3 having a hot water spray 11. Steam from the scrubber passes to a compressor 4 supplied with high pressure steam from pipe 12 and the mixed steams pass to a heat exchanger 5 in which hot water from an economizer 6 is evaporated to form steam which passes by pipe 16 to the retort, a part traversing the hot coke in chamber 7 where it is heated while cooling the coke. Gas evolved with the dirty steam together with some steam passes by pipe 24 to a condenser 23. Condensed steam enters the economizer by a pipe 17, clean water enters by pipe 20 and condensates from the scrubber 3 by a pipe 21.

Filed: 1923-07-04
Abstract: Carboxylic acid chlorides are produced by treating a free carboxylic acid with a sulphochloride in the presence of a soluble diluent, which may comprise an inorganic salt such as alkali chloride, neutral sulphate, or pyrosulphate, or a dry powdered indifferent body, such as Kaolin or sand.  Preferably at least two molecular proportions of the sulphochloride, which includes alkali chlorosulphonates and aryl sulphochlorides, are used for each molecular proportion of the carboxylic acid. According to the examples, (1) one molecular proportion of glacial acetic acid is slowly added with continual stirring to a heated mixture of two molecular proportions each of sodium chlorosulphonate and sodium chloride; acetyl chloride distils off and is collected in a series of condensers, the first of which are cooled by water, others by a refrigerating liquid and the last by solid carbonic acid or liquid air; the crude product is purified by rectification; the process may be carried out in a continuous mannef; (2) one molecular proportion of glacial acetic acid is added to a mixture of two molecular proportions of sodium chlorosulphonate with one-half to one molecular proportion of sodium pyrosulphate, and the acetyl chloride distilled off; the residue, after removing the excess of glacial acetic acid, is utilized in part as a diluent for the next operation; (3) two molecular proportions of both p-toluenesulphochloride and common salt are heated together and one molecular proportion of glacial acetic acid is added with continual stirring; acetyl chloride distils off and is collected as before; the residue contains p-toluenesulphonic acid anhydride; benzenesulphochloride may replace the p-toluenesulphochloride; (4) one molecular proportion of glacial acetic acid is boiled with one molecular proportion of common salt and one molecular proportion of p-toluenesulphochloride or benzenesulphochloride is slowly added; acetyl chloride distils off.  In the examples, potassium salts may replace the sodium salts, and by using chloroacetic acid, propionic acid or butyric acid in place of the acetic acid, chloroacetyl chloride, propionyl chloride and butyryl chloride are obtained. Specification 24255/02 is referred to.

Abstract: 145,672. McKinnon Industries, Ltd., (Assignees of Boblett, K. M.). Oct. 1, 1914, [Convention date]. Radiators.-In bending metals into a succession of oppositely-disposed loops to form sheet-. metal radiators for automobiles &c., the metal is alternately bent so as to form an offset portion, and the offset portion then bent intermediate its end towards the finished portion. In the form shown in Figs. 5 and 6, a continuous sheet-metal strip is bent to the form shown at a, b, c, d between dies 4, 5, one wall of the die 5, consisting of a split mandrel 6 which has just formed the preceding lower loop. The mandrel is then withdrawn endways and the strip fed along through the space of one loop. The mandrel is then rotated on an axis x to bring it into an horizontal position and is then pushed forward so that its slit engages the arm a, b of the strip. It is then rotated on the axis x to bend the part b, c about the point c<1> and so bring the end a against the part c, d to form the lower loop. The die 4 is then again brought down and bends the inclined portion of the strip to complete the top loop and form the U-shape for the next loop. In order to form lateral shoulders and recesses 2 serving as water channels at opposite sides of the loops and to form longitudinal grooves 3 in each loop, Fig. 1, the die 4 has a forming-face 8 provided with ribs 7, the mandrel has grooves 12 at each side and also inclined shoulders 11 at the ends of the grooves, and the lower die 5 has forming-faces with ribs corresponding to the ribs 7. If the product is straight throughout or tapered in one direction only or provided with only one set of shoulders or off-sets, a single mandrel only need be employed, but if the construction is as shown in Fig. 1, a mandrel at each end is used. Radiators of the form shown in Figs. 2 and 3 may also be similarly made. In making a radiator, as shown in Fig. 2, an offset split mandrel 14, Fig. 9, is used. The metal strip is first bent into substantial I-shape between the die 13 and a die 13<1>, one wall of which is formed by the mandrel when in its upright position. The mandrel is then withdrawn, rotated on an axis 15, and the strip fed forward. The mandrel is inserted in the position shown and then rotated again into its upright position. In making a radiator as shown in Fig. 3, the mandrel consists of two right-angled triangular portions, Fig. 11. The strip is first bent by the die 13 to L-shape, with the mandrel in its upright position, and thereafter the operations are as for those previously described, the mandrel rotating on an axis 17.
