Abstract: 1,122,556. Control of D.C. motors. ETABS. BRISSONNEAU ET LOTZ. 15 March, 1967 [14 April, 1966], No. 12081/67. Heading H2J. In an electrically propelled vehicle, wheel slip is detected by comparison of the current taken by each motor in a pair and correction effected by strengthening the field of the slipping motor. The motor fields 8a, 8b are separately excited by a closed loop system in which the actual field current, measured at 13a, 13b, is compared with a reference value UIe, and unbalance between the motor currents produces a signal from the appropriate comparator 2a or 2b which is differentiated at 3a, 3b and added to the field reference value. As shown, the fields are energized from a separate A.C. source and control is effected by thyristors or thyratrons 11a 11b, but in an alternative arrangement a D.C. generator energizes the fields via series resistors which are short circuited by relay contacts when slipping occurs.

Title: Improvements in or relating to grinding machines
IPC: B24B19/12
Filed: 1920-05-03
Abstract: 168,623. Wade, H., (Norton Co.). May 3, 1920. Disc apparatus. - A machine for grinding cams on a cam-shaft - comprises a swinging frame, in which the work is mounted and continuously rotated at a constant velocity ratio from a stationary source of power. A shaft 12, Figs. 1, 2 and 3, on which are cam-blanks to be ground, is carried in a frame 1 pivotally mounted on supports 8, 10 on a table 3, which is slidable on a base 4. The shaft 12 is rotated by a lug 17 and a dog 18 from a spindle 20 carrying removable mastercams 21. Spiral-springs 42 with adjustable tensioning-means, or a weight and pulley, tend to swing the frame 1 so that the work 12 approaches a grinding-wheel 40, which is mounted on a fixed axis. The rotating master-cam 21 contacting with a revoluble shoe 22 on a fixed spindle 23 oscillates the frame 1 and causes the cam-blank opposite the grinder 40 to be ground to a corresponding contour. The shaft 20 receives continuous rotation from a shaft 63 in stationary bearings through gears 66, 65, a telescopic shaft 57, and gears 56, 55. The shaft 57 and its gears 56, 65 are mounted in housings 58, 78 respectively journaled on the shaft 20, 63. The shaft 57 is slidably keyed to the worm-wheel 65 by balls running in keyways. Bevel gears may be substituted for the worm and worm-wheels. A drum 48 on the shaft 20 is frictionally engaged by an adjustable band-brake held against rotation by a pin 47, and thus prevents back-lash, The shoe 22 is set opposite the required master-cam 21 by rotating a hand-wheel 30 on a spindle 29 and, through bevel-wheels 27, 28, a screwed spindle 26, which engages a yoke 25 straddling the shoe 22 and slides the latter along its spindle 23. A block 33 engaging a screw-thread on the shaft 29 indicates which master-cam is being used. As the sliding table 3 is moved to bring a fresh blank opposite the grinder 40, the spindle 26 may be rotated automatically through gears 113, 114, Fig. 11, by a pinion 111 engaging a rack 110, which is adjustably secured to the base 4 so as to allow of various sized pinions 111 being used according to the distance between the cam-blanks. A lost motion connection between the pinion 111 and its shaft 112 allows of the work being traversed across the grinder without shifting the shoe 22 from the corresponding master-cam, A handlever 100 connected by a rod 101 to a pin-lever 102 serves to swing the frame 1 away from the grinder when a new cam-shaft is inserted. The master-cams are made by reversing the arrangement of the grinder and the shoe, but keeping to the same radial dimensions of the rotating parts contacting with the cams and master-cams.

Patent GB-731874-A (GB)
Title: Catalytic hydrogenation
IPC: C07C215/68
Filed: 1953-05-06
Abstract: A process for the production of a monocyclic amino-aryl lower alkyl-carbinol comprises reducing a monocyclic nitro-aryl lower alkyl ketone with hydrogen in the presence of a catalyst in two steps, in the first of which the catalyst is a metal hydrogenation catalyst the metal of which is in Group VIII of the Periodic Table while in the second the catalyst is a copper chromite hydrogenation catalyst and hydrogen acts under a pressure of at least 1000 pounds per square inch gauge.  A "lower alkyl" group contains up to 6 carbon atoms. Preferably the first step is terminated when hydrogen to the extent of about 3 molecules per -NO2 group has reacted.  This first step can be conducted in several stages.  Suitable catalysts are Raney nickel, Raney cobalt, palladium or platinum.  Reaction temperatures of 20 DEG to 100 DEG  C., preferably 30 DEG  to 50 DEG  C. are suitable.  In the second step, after removal of the metal hydrogenation catalyst the products are subjected to the second hydrogenation, which may be effected at a pressure of 1000 to 10,000, preferably 4000 to 5000, pounds per square inch gauge and at temperatures of 50 DEG  to 250 DEG  C., preferably 100 DEG  to 160 DEG  C.  The amount of catalyst in each step may be about 2 to 50 per cent by weight of the starting monocyclic nitroaryl lower alkyl ketone.  The hydrogenation may be effected in the presence of a solvent such as alcohol, tetrahydrofuran, dioxane, methyl cyclohexane, methylal or ether. Suitable starting materials are m-nitrophenylmethyl ketone, which yields m-aminophenylmethyl carbinol and m-nitrophenylbutyl ketone which on hydrogenation yields m - aminophenylbutyl carbinol.  The ketone may have nuclear alkyl substituents, e.g. methyl, ethyl, propyl, butyl or amyl, as in 3-nitro-4-methyl-acetophenone and 4-nitro-2-ethylphenyl propyl ketone.  In examples: (1) m-nitro-acetophenone is hydrogenated at 24 DEG  to 37 DEG  C. in denatured alcohol using a Raney nickel catalyst until 3 mols. of hydrogen per mol. of ketone have been taken up.  The product after filtration is hydrogenated at 150-155 DEG  C. and 4700 to 4800 lbs. per square inch with a copper chromite hydrogenation catalyst to give m-aminophenylmethyl-carbinol; (2) a similar process is effected using tetrahydrofuran as the solvent, in the first stage the temperature gradually increasing from 22 DEG  to 45 DEG  C. and in the second stage pressures of 3500 to 4700 lbs. per square inch and temperatures between 126 DEG  and 145 DEG  C. being used.
