Abstract: 396,316. Copying-machines. PRATT & WHITNEY CO., 436, Capitol Avenue, Hartford, Connecticut, U.S.A. Feb. 16, 1933, No. 4758. Convention date, Nov. 7, 1932. [Class 83 (iii).] Milling-machines.-In a copying-machine of the kind comprising a fixed base 10 carrying a movable column 15 fitted with a vertically reciprocating carriage 16 on which is mounted a head 14 carrying a cutter 12 and tracer 13, the support of the model M is movable in the same direction as the column through twice the distance thereof so that a right-hand model may be used for reproducing the corresponding left-hand work-piece or vice versa. The axial movements of the cutter and tracer with the head 14 are controlled through electromagnetic clutches of known type and the column is fed horizontally after each vertical reciprocation of the head until the work is finished. A bridge 21 having uprights 20 which span the workpiece W has horizontal ways, parallel to the direction of the column movement, to receive a carriage 22 which has brackets 23 for securing the model. The bridge carries a fixed rack 25 engaged by a pinion 27 rotatable in a saddle connected by a bar 29 to the column, and the upper part of the pinion engages a parallel rack 26 secured to the carriage 22. During movement of the column the pinion rolls along the fixed rack and moves the model carriage through twice the distance traversed by the column thus changing the "hand" of the reproduction as shown in Fig. 3. In a modification, the uprights 20 and associated parts may be mounted on rollers and may be moved away from the tool and tracer mechanism when the above described model-supporting mechanism is not required.

Title: Improvements in process for preparing isophorone
IPC: C07C45/74
Filed: 1939-02-15
Abstract: 525,142. Isophorone. CARBIDE &CARBON CHEMICALS CORPORATION. Feb. 15, 1939, No. 4908. Convention date, March 19, 1938. [Class 2 (iii)] Isophorone is prepared by contacting acetone vapour with a condensation catalyst consisting of one or more of the compounds calcium oxide, calcium hydroxide or calcium carbide at a temperature within the range 200‹-700‹C. It is preferred that the catalyst should be maintained in finely divided form, and that the temperature used should be between 300‹- 450 ‹C. The reaction products are preferably rapidly withdrawn as soon as they are formed, and fractionally distilled to separate the isophorone from unchanged acetone and mesityl oxide and higher condensation products. In examples (1) Acetone vapour is passed over calcium carbide at 400‹C. for 6 hours, and the reaction products fractionally distilled. (2) 20-Mesh calcium carbide and steel balls are placed in a ball mill and acetone passed through at 400‹C, the mill being revolved at 40 r.p.m. The reaction product is fractionally distilled. (3) Acetone vapour is passed through a reaction tube six inches diameter filled with lime pellets and heated to 350‹C. The products were passed first through a condenser cooled with water maintained at 60‹C. and then through a stripping vessel maintained at 100‹C. and a final condenser maintained at 10‹C. The condensates from the first condenser and the stripping vessel are redistilled and a fraction boiling under 20 mms. pressure at 100‹-105‹C. yields pure isophorone. The higher boiling fractions consist essentially of two ketones which are easily separated. The higher boiling one which boils at 143‹C. under 10 mms. pressure has the composition C 15 H 22 O, whereas the lower boiling one which boils at 130‹C. under 10 mms. pressure and has the composition C 12  H 18 O.

Title: Improvements in the manufacture and production of liquid hydrocarbons of low boiling point from olefines
IPC: B01J19/02
Filed: 1927-02-22
Abstract: 291,137. Johnson, J. Y., (I. G. Farbenindustrie Akt-Ges.). Feb. 22, 1927. Liquid hydrocarbons of low boiling-point are obtained by passing olefines or gases containing them at elevated temperature and ordinary or increased pressure over catalysts comprising (1) gold, silver or copper in a coherent form, e.g. as turnings or gauze or a lining to the reaction tube, (2) compounds, preferably oxygen-containing compounds, of the alkali metals, to which may be added other metallic salts or oxides, (3) salts of the oxygen acids of phosphorus, boron or antimony, with alkali or other metals, e.g. calcium phosphate, zinc antimonate or copper borate, or their reduction products, e.g. zinc antimonide, or the acids or anhydrides themselves when in the solid form, e.g. mounted on a carrier, or mixtures thereof. Materials such as iron and nickel which give rise to the formation of carbon are excluded, as also rough surfaces, and for this reason the interior of the reaction vessel may be lined with copper, silver, quartz or ferrosilicon; the gases should be free from sulphur. Methane or gases containing or furnishing methane may be added, whilst the residual gases may be recirculated. At temperatures of 300-400‹ C., the product mainly comprises liquid: olefines; at 550‹ C., the bulk consists of benzene hydrocarbons and naphthenes. If desired, the olefines may be first isolated from olefine-containing gases, e.g. by fractional liquefaction or adsorption, and these converted into liquid hydrocarbons. According to the examples (1) brown-coal tar is decomposed a.t 700‹ C. and the gases are passed at 500‹ C. and a pressure of 50 atmospheres through a copperlined tube and the hydrocarbon products separated by cooling; (2) coal tar, low-temperature tar or brown-coal tar is injected into superheated steam and led through a heated ferrosilicon tube; the resulting gaseous olefines are then converted into liquid products by passage at ordinary pressure and a temperature of 850‹ C. over pumice and potassium bichromate; (3) gases containing ethylene, propylene, butylene and methane are conducted through a copper tube, which may contain copper gauze, heated to 850‹ C.; (4) gases containing ethylene and propylene such as are obtained by the partial liquefaction of coke-oven gas are passed at 700‹ C. under ordinary pressure over granulated di-potassium phosphate ; natural gas, oil gas, cokeoven gas, and gases obtained by the catalytic heat treatment of methane may be used in this process; (5) oil gas is led at ordinary pressure through a quartz tube containing a mixture of calcium pyrophosphate and copper bronze which is heated to 630-670‹ C.; borates, boric acid or phosphorus pentoxide deposited on pumice may be employed as catalyst. Specification 17235/12 is referred to.

Filed: 1942-04-16
Abstract: 581,730. Measuring angles. HAGNER, F. H. April 16, 1942, No. 5089. [Class 97 (ii)] [Also in Group XIX] An angle-determining instrument comprises an observation tube, an altitude arc constituting a quadrant carried by the tube, a recording mechanism pivotally suspended in pendulumlike manner adjacent the tube, and means for locking the recording mechanism in a set position relative to the quadrant. The instrument as shown in Figs. 1 and 3 has a handle 10 attached to a head portion 12 that carries an observation tube 11. To the tube is secured a graduated quadrant 25 and extending from the head portion is a shaft 31 on which is freely suspended, adjacent the quadrant, a hanger 30 carrying a micrometer screw adjustment 27 for co-operation with rack teeth 26 on the quadrant. The handler 30 also carries a bracket 67 to support an eye-piece or viewing tube 57. The shaft 31 is provided with a ballbearing journal for a recording housing 33. The housing includes a pair of spools 59 carrying a record strip 60, a ball magazine 47, means for feeding a ball to the delivery position, and a magnetic element 38 that operates to release the ball to permit it to fall freely on to the record strip. The record strip passes over a glass plate 56 at the inner end of a socket 58 adapted to receive the viewing tube 57. The ball magazine supplies the balls one at a time to a valve 46, the rotation of which delivers it to a tube 45. A supporting element 52 is raised to its dotted position, Fig. 3, by depressing a trigger 54 so as to retain momentarily the ball until it is firmly held by the magnet 38 slidably mounted in a bore 51. The magnet 38 is connected to a bell-crank lever 41 and is raised to release the ball by the action of a cam 42 on a spindle operated by a trigger 44 on the handle. A hinged plate 62 carrying an ink-ribbon is swung down to position over the record strip before a record is taken. In operation, the sun, star or other object is aligned with the observation tube and a latch 35 is operated to free a brake 36 which permits the housing 33 to swing to a substantially vertical position. A ball is then fed to its delivery position and the trigger 44 operated to effect its release and the operation repeated a number of times. To average'the record, the viewing tube 57 is inserted in the socket 58 and the micrometer adjusted accordingly. The eye-piece 14 of the observation tube 11 comprises a plain glass panel 15 with a lightvarying segment 16, Figs. 1 and 7, having graded apertures 19, 20 and 21 clear and/or shaded. The objective panel is made of glass with a central luminous spot of transparent luminous material.

Abstract: 970,887. Pipe joints. L. M. C. SEAMARK. Jan. 29, 1963 [Feb. 9, 1962; Jan. 17, 1963], Nos. 5125/62 and 2196/63. Heading F2G. A pipe coupling comprises a gapped and/or slotted sleeve 1 with serrations 2 on its inner periphery and buttress screw-threads 4 on its outer periphery, having an inner diameter smaller than, and adapted to be forced on, each of the pipe ends 3 to be coupled and a clamping member 6 having internal buttress screwthreads 5 to engage with the screwthreads 4 for limited axial movement with respect to the clamping member, causing an inwardly directed radial component of force to be applied to the pipe end. Axial movement will occur, when the clamping member 6 is rotated, until the inner ends of the sleeves 1 bear up against the outer sides of annular flanges 8 in the member 6 and then further rotation causes over-riding of the buttress screw-threads and consequent inward pressure on the gapped sleeves 1, causing the serrations 2 to bite into the outer surfaces of the pipes. The buttress threads may be lefthanded at one end and right-handed at the other, in which case the coupling is assembled by the rotation of the clamping sleeve; or the threads at both ends may be similar, in which case the coupling is assembled by screwing the clamping sleeve on to one pipe and then inserting and rotating the other. The distortion of the gapped sleeve 1 under inward pressure may be furthered by longitudinal slots which extend over part of its length. The clamping member may be angled and may have a tapered internal flange, against which pipe ends may abut, to couple together pipes not in axial alignment. By having two clamping members 13, Fig. 6, adapted to be held together by a flanged sleeve 18 and having their inner end faces cut at an angle so as to abut the two sides, of a tapered middle member 14, which is also held by the flanged sleeve 18, the angle between the pipes 3 may be varied by rotating the middle member 14 relatively to one or both of the clamping members 13. In all embodiments, recesses are provided for sealing rings.
