Title: Improvements in milling machines
IPC: B23C1/025
Filed: 1921-03-21
Abstract: 160,468. Conradson, C. M. March 20, 1920, [Convention date]. Milling-machines.-In a milling machine of the horizontal spindle type modifications are made in the spindle drive, frame-work, feed mechanism, and other details, as follows :- Driving machine spindle. -An electric motor 30 is supported by an extension 27 bolted on the side of the pillar 20 carrying the tool spindle 21 in bearings 22, 23. The spindle drive is through sliding change speed and reverse gearing 31-54 operated by hand levers having spring-controlled stop pins to hold them in the set positions. These gears drive a pinion 62 which engages one of a set of four or more wheels mounted en shafts 66a &c. carried in a cage or tumbler 63 having eccentric bearings 65 arid turned by a hand-operated worm and worm wheel 70, 72 with indexing gear so as to engage one of the sets of gears with its corresponding gear 87 on the spindle 21. Framing and supports.-A supporting bar 90 has tapered grooves 91 engaging wedges 96 having differentially-threaded screws 102 to clamp the bar 90 very firmly to the frame 20 and to a spindle support 103. A vertically-extensible clamping frame 103<a> at the front of the machine gives further rigidity to the frame when the table 106 has no vertical movement. Work-tables; work-table feeds.-The table 106 is angularly adjustable about the bearing between the support 255 and cross-slide 256. The feedscrew 273 for the longitudinal traverse, the screw 229 for the transverse traverse, and the telescopic screw 112 for the vertical movement of the table are all operated by change speed and reversing gearing 146, 193, 210, 152, 225 controlled by conveniently placed hand levers. The change-speed gear is preferably of the type having tubular shafts 193, 210 with internal spring-pressed keys to engage any one of the wheels 208, 209 according to the position set by hand-operated setting devices acting through rack-like ends 203, 218 on the shafts. In addition each traverse has its own clutch-operated controls for its separate operation. The reversing gear for all the table feeds comprises a dog clutch for the low speed, and a friction clutch for the high speed, both mounted on the shaft 152, and actuating the shaft 224 through change-speed gear as set forth above. The stop motion for the longitudinal traverse of the table acts through adjustable stops acting through levers and a rack bar on a link on the telescopic shaft 238, the link 300, and the clutch devices acting on the main stop motion on the shaft 152. Similar stop motions are provided for the transverse and vertical movements of the table.

Title: Reading device on a balance
IPC: G01G23/32
Filed: 1961-03-15
Abstract: 918,319. Weighing. METTLER, E., [trading as METTLER, FABRIK FUR ANALYSENWAAGEN, E.]. March 15, 1961 [Oct. 26, 1960], No. 9543/61. Class 143. A glass plate 15 is fixed to the end of the weigh beam 10 and moves in an arc through a distance according to the weight in the pan. The plate is calibrated in figures representing whole numbers, with graduation lines to correspond. A light beam from a lamp 18, directed by a lens 19, projects an optical image of the calibrations, through a magnifying lens 20 and by way of a deviating prism 21, on to the plane face of a planar-convex (or planar-parallel) collecting lens 22. As the beam is directed towards the lens 22 it passes through a glass plate 24 which is mounted in a holder 25 in which are recesses 28, 29 entered by pins 26, 27 whereby it may be tilted. The tilting mechanism comprises a cam 34 on a shaft 33 which is rotatable, through gearing, by a knob 30 and a pin 36 projects from the holder 25 and engages the cam 34. Fixed to the shaft 33 is a glass disc 38, a surface of which faces close to the plane face of the lens 22 and is calibrated in figures representing decimal numbers. At the place on the plane face of the lens 22 where the magnified image of a graduation line appears, the lens face has a mark in the form of two slightly spaced triangles. This mark 23, the magnified image 16<SP>1</SP> of the whole numbers, the magnified image 17<SP>1</SP> of the graduations, and the decimal numbers 39, on the dies 38, then appear as in Fig. 4, which shows the total image as would be seen when looking through the glass disc 38 in the direction of the lens 22. The image is further magnified, and also spread, by an optical system comprising a rhombic prism 42 and lenses 43, 44. The optical rays corresponding to the numbers 16<SP>1</SP> are diverted through the prism 42, magnified by the lens 43 and projected on to a ground glass screen 40 to form an image 16<SP>11</SP>, Fig. 5. The numbers 39, graduations 17<SP>1</SP> and mark 23 are magnified by the lens 44 and projected to form images 39<SP>1</SP>, 1711 and 23<SP>1</SP>. A cover 45 on the screen 40 has three windows which cause the image to show up as shown in Fig. 5. Alternatively the cones could be on the lens 22. The whole number of the weight is read off in the left-hand window, as seen in Fig. 5, and the decimal number of the weight is precisely determined by tilting the lens 22, through operation of the knob 30, till the corresponding graduation appears in the space between the two triangles 23<SP>1</SP> of the magnified image of the mark 23, the operation of tilting the lens also causing the dies 38 to rotate and bring the image of the decimal figure carried by it into the right-hand window as seen in Fig. 5. The device may be simplified by omitting the prism 42 and lens 43 and arranging the calibrations to give the required spread of the images.
Patent GB-571654-A (GB)
Title: A process for the production of toluol
IPC: C07C15/06
Filed: 1941-07-28
Abstract: Natural and synthetic hydrocarbon distillates containing appreciable quantities of naphthenic and paraffinic hydrocarbons having 7 carbon atoms are fractionated, and the fraction containing mostly hydrocarbons with 7 carbon atoms separated into a lower boiling fraction comprising dimethylcyclopentanes and methylhexanes and a higher boiling fraction comprising methylcyclohexane and n-heptane. The lower boiling fraction is then heated in the presence of a metal halide isomerisation catalyst to convert the dimethylcyclopentanes into methlcyclohexane and subjected to dehydrogenation, if desired, in the presence of the higher boiling fraction to give toluene.  The isomerisation catalyst may be in the solid condition or in the liquid condition in association with organic acids, ethers, esters or hydrocarbons.  The aluminium halides may also be used in molten condition in combination with halides of Sb, Sn, Zr, Cu, Ti, Na, K and Li.  Catalysts in the liquid condition may be continuously circulated.  A hydrogen halide promoter is preferably employed. This may be introduced into the reaction mixture or generated by the addition of organic halides, phenol, alcohols, PbSO42HCl or CuSO42HCl.  The isomerisation may be effected in the presence of hydrogen.  In an example, the isomerisation catalyst is prepared by combining aluminium chloride with a kerosene extract containing aromatic hydrocarbons, and the isomerised product is either returned to the naphthenic hydrocarbon feed or is dehydrogenated together with the higher boiling naphthenic fraction.  For the dehydrogenation, mixed nickel and tungsten sulphides or oxides of metals of the 4th, 5th or 6th Group of the Periodic Table may be used as catalysts.  If necessary, the toluene produced may be purified by fractional, azeotropic or extractive distillation or by crystallisation or solvent extraction.
