Title: Improvements in the manufacture and production of high quality benzine and diesel motor fuels
IPC: C10G47/00
Filed: 1938-08-29
Abstract: 505,953. Motor fuels; destructive hydrogenation of tars and oils. UHDE, F., and PFIRRMANN, T. W. Aug. 29, 1938, No. 25287. Convention date, Aug. 30, 1937. [Classes 32 and 91] Gasoline and Diesel fuels are made from tars such as brown coal, low or high temperature, or producer tar, by treating the tar with a middle oil obtained in the reduction of carbon monoxide with hydrogen and separating the extract from the heavy oil residue, the extract being then hydrogenated in the gas phase and the oil residue hydrogenated in the liquid phase to form fuels. In an example, brown coal tar is mixed with an equal weight of the middle oil, boiling at 180 to 220‹ C., at normal or at elevated temperature, to form an extract of non-aromatic hydrocarbons and low boiling phenols, and an oil residue of asphaltic and aromatic hydrocarbons, and high molecular phenols. The two phases are separated by sedimentation or centrifuging. The extract layer, from which some of the middle oil may be removed, is hydrogenated in the gaseous phase at 420 to 440‹ C. with sulphur-immune catalysts, and a gasoline fraction boiling up to 200‹ C. is taken off leaving a readily ignitable Diesel oil. The oil residue is hydrogenated in the liquid phase under pressure and at 450 to 500‹ C. with finely divided tin or molybdenum as catalyst, to yield a gasoline, a middle oil and also a heavy oil fraction which is recycled. The middle oil may be further hydrogenated to form gasoline, or it may be blended with the Diesel fuel obtained from the extract.

Title: Apparatus for controlling the density of a fibre feed mat
IPC: D01G23/00
Filed: 1972-05-30
Abstract: 1351413 Lap-forming machines CURLATOR CORP 30 May 1972 [7 June 1971] 25302/72 Heading DIN [Also in Divisions F2 and G3]  A lap forming device, which deposits airborne fibres onto a moving foraminous condenser 86, comprises means 250 for monitoring the air pressure in the air stream and varying the rate of flow of air to the condenser to compensate for differences in the air flow. As shown, fibre tufts from a hopper are fed from conveyor 40 in an air stream to a rotating foraminous drum 85. The air stream continues through the drum, past pressure gauge 250 to suction fan 70 and then to the atmosphere via damping plug 300. The position of the plug 300, and thus the air flow, is controlled by the pressure gauge 250 to keep the rate of flow of fibres and air to the drum constant. The pressure gauge acts on the damper plug 300 via electrical circuits (Figs. 3 and 4 not shown) and a reversible motor on a rack and pinion or worm wheel drive for the damper plug. A butterfly valve may replace the movable damper plug 300. Alternatively, the air flow through the condenser drum may be controlled by a variable speed motor driving the fan.

Such compounds are obtained by quaternizing a compound of the general formula: <FORM:0790800/IV (b)/2> with a quaternizing agent of the general formula R1X where Z1 is a nitroso radical or an organic radical containing not more than seven carbon atoms and is a carbalkoxy, benzoyl, N-dialkylcarbamyl, carbamyl or acetyl radical, compounds wherein Z is hydrogen being prepared by the additional step of hydrolysing compounds wherein Z is a carbalkoxy radical or of hydrogenating compounds prepared from those wherein Z1 is a nitroso radical.  In examples: (1) N-carbethoxy-N1-nonylpiperazine is reacted with methyl iodide to give N-carbethoxy - N1 - methyl - N1 - n - nonylpiperazinium iodide; (2) N - carbethoxy - N1 - methylpiperazine and n-dodecyl bromide are reacted to give N-carbethoxy-N1-methyl-N1-n-dodecylpiperazinium bromide; (3) N-nitroso-N1-benzylN1-methyl-piperazinium chloride is hydrogenated using a Raney nickel catalyst to give N-benzyl-N-methylpiperazinium chloride hydrochloride.  In a generally similar manner to (1) there are prepared (4) N-carbethoxy-N1-allyl-N1(a  - carbethoxyethyl) piperazinium bromide; (5) N - methyl - N - n - tridecylpiperazinium chloride hydrochloride; (6) N - benzoyl - N1-methyl - N1 - n - dodecylpiperazinium bromide; (7) N - dimethylcarbamyl - N1 - methyl - N1-benzylpiperazinium chloride; (8) N - carbethoxy - N1 - methyl - N1 - (2 - heptynyl) - piperazinium bromide.  A list is given of similarly prepared compounds, the radicals in specific compounds being selected from (at Z) carbethoxy, carbomethoxy, benzoyl, acetyl, carbamyl, dimethylcarbamyl and hydrogen; (at R) methyl, ethyl, butyl, benzyl, phenethyl and allyl; and (at R1) heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, undecenyl, propynyl, heptynyl, benzyl, p-chlorobenzyl, 2,4-dichlorobenzyl, p-methoxybenzyl, o- and m-methylbenzyl, phenylallyl, benzoylmethyl, a - or b -thenyl, carbdodecyloxymethyl and a -carbethoxyethyl radicals.  N - benzoyl - N1 - methylpiperazine and N - dimethyl - carbamyl - N1 - methylpiperazine are prepared by reaction of N-methylpiperazine with the appropriate acid chlorides.

Title: Electric discharge machining apparatus
IPC: B23H7/18
Filed: 1960-07-21
Abstract: 900,686. Automatic control systems for spark machining apparatus. GENERAL MOTORS CORPORATION. July 21, 1960 [Aug. 7, 1959], No. 25429/60. Class 38 (4). [Also in Group XXIX] Spark machining apparatus is controlled in such a manner that the width of the gap between the electrode and workpiece is maintained at a predetermined value and that the speed at which the electrode is retracted from the workpiece is greater than the speed at which the electrode is fed towards the workpiece. A workpiece 12 is immersed in a tank filled with a dielectric liquid so as to be a predetermined distance from an electrode 10, the electrode position being altered by a fluid-pressure actuated system 16 and the power supply 14 to the electrode and workpiece being of the capacitor charge/discharge type giving intermittent sparking. The position of the electrode 10 is controlled according to the output of a circuit 96 into which are fed four signals:-a reference signal 100 which is representative of the required electrode position; a dither signal 104 which overcomes static friction in the fluidpressure system; a signal 108 which is representative of the actual position of the electrode 10 and lastly a signal from an electromagnetic device 122 which varies in polarity according to which the electrode 10 is moving towards or away from the workpiece 12. The resultant of these signals is fed to an amplifier 94 which energizes one or other of relays 78, 80 to move a reed 64 whereby the fluid-pressure device is caused to move the electrode 10 until the gap width attains the value set by the signal 100. The signal from the device 122 is associated with a circuit which includes a diode 134 so that the effect of the signal when the electrode 10 is being retracted is limited thereby causing rapid retraction of the electrode. When the electrode is being moved towards the workpiece the signal is not limited by the diode 134; thus the forward movement of the electrode is slower than that of retraction.

Title: Improvements in or relating to machines for performing lasting or analogous operations upon shoe parts
IPC: A43D21/02
Filed: 1945-10-05
Abstract: 598,216. Lasting-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. Oct. 5, 1945, No. 25922. Convention date, Oct. 26, 1944. [Class 17 (i)] A machine which may be used to perform a lasting operation on a shoe upper or to tension a pLatform cover of a slip-lasted shoe heightwise and work its margin over on to the platform and there secure it, as by cement, has means to engage the bottom of a shoe adjacent the marginal edge thereof and means for seizing the lasting margin and pulling it over the shoebottom-engaging means in a direction substantially parallel to the bottom of the shoe to tension the upper or cover, as the case may be, in a direction substantially normal to the shoe bottom. The illustrative form of machine described has a rapidly reciprocating gripper with jaws 10, 12 which seizes the lasting margin of the stock to be lasted, in different locations successively along the edge of the shoe bottom and tensions it heightwise by pulling it inwardly from the edge of the shoe bottom in a direction substantially parallel to the bottom over a protective shield portion of a shoe bottom rest 14 which positions the shoe heightwise on the machine. The bottom rest is movable by spring means to inoperative position and is returned to operative position against the spring by operator-controlled means which also hold the front gripper jaw 12 in its forward position away from the reciprocating rear jaw 10. A presser-feed member 16 operating in time relation to the gripper presses and pounds the overdrawn adhesively-coated lasting margin of the stock into adhering relation with a shoe bottom part and thereafter, while still pressing against the stock, exerts feeding force on the work. A feed-retaining member 18 in the form of a narrow blade with sharp teeth holds the shoe against retrograde movement during the return, or back movement of the feed member 16, applies supplemental pressure to the cover at a point adjacent the feed foot 16 and also retains the overlasted stock from displacement by the next successive action of the gripper. The amount of pull may be varied by changing the tension of a spring 150, and the duration of the pull also may be varied. A slight additional forward movement is given to the front gripper jaw, by a cam 124, to separate it from the sticky inside surface of the cover to facilitate the lasting and feeding operations. An edge gauge roll 20 positions the shoe laterally. These parts 'are mounted on, and operated by mechanism contained in, a hollow head 22 having a removable top part 26. The main driving shaft 52 of the machine is driven at approximately 1,200 revolutions per minute effecting about twenty complete lasting cycles each second and involving about 2¢ inches movement of the shoe per second.
