Title: Control systems for diesel-electric drive units
IPC: B60L50/11
Filed: 1965-01-25
Abstract: 1, 083, 722. Automatic speed and power control. CATERPILLAR TRACTOR CO. Jan. 25, 1965 [Feb. 13, 1964], No.3126/65. Heading G3R. [Also in Division H2] In a constant-power diesel-electric system for supplying traction motors, a control field winding 42 of the generator is energized in accordance with the deviation of the engine speed from a set value, the field winding being connected in series with a transistor 39. When manual controller 19 is adjusted to supply more fuel to the engine, rotor 54 of transducer 46 is moved to increase the voltage across secondary 57 whereby transistor 47 is biased to decrease the energization of winding 42. The load on the engine decreases, so that its speed rises to increase the voltage developed across resistor 52 from tachometer 24. This causes the transistor 47 to pass more current, so increasing the excitation of winding 42. When controller 19 is adjusted for decreased power, the energization of field winding 42 is increased so applying more load to the engine which decelerates. When the desired operating speed is attained, the current through winding 42 will reach a steady value. An R. C.-circuit 61, 63, controls the rate of unloading of the engine during acceleration, and affords a quick response to an initial call for acceleration. When the wheelspeed becomes excessive, a tachometer 66 develops sufficient voltage to break down Zener diode 72. This increases the potential at emitter 49 to decrease the excitation of winding 42 whereby the motor-power is decreased. For dynamic braking operation, switch 76, 76', is changed over so that braking resistor 78 is now connected to emitter 49. The degree of braking afforded by the traction motors depend upon the current supplied to the motor fields by the generator, and the wheel speed. As the engine speed is increased, a higher voltage is established across the braking resistor 78 to cause a balanced condition in which coil 42 draws steady current.

Title: An improved catalytic alkylation of paraffins and olefins
IPC: C07C2/60
Filed: 1944-02-28
Abstract: A continuous process for alkylating isobutane or isopentane with ethylene or propylene comprises directly introducing the feed stock into a reaction zone, recycling through an aluminium chloride pick-up chamber and back to the reaction zone until a liquid aluminium chloride-hydrocarbon complex is formed, separating products from the complex and recycling at least part of said products to the reaction zone through the pick-up chamber, the amount of aluminium chloride required over a given period being added to said chamber in portions at intervals spaced over that period.  A reactor 1, packed with Raschig rings, is filled with isobutane which is saturated with ethylene at the operating pressure, isobutane and ethylene <PICT:0597210/IV/1> then being fed by pipe 2.  A portion of the necessary aluminium chloride is placed in pick-up chamber 18 through which the hydrocarbon feed is recycled via lines 10, 11, 19 and 22. Aluminium chloride leaving reactor 1 is removed in separator 5 and gravitates back.  The catalyst complex forms and product is in part withdrawn through line 15 for separation of alkylate.  Spent catalyst is withdrawn when necessary at 21 while portions of fresh chloride are added to chamber 18, for example at intervals of 2 hrs. during the first 8 hrs. of operation and then at less frequent intervals. Two or more chambers 18 operate in parallel to avoid stopping. Temperatures of 90-175 DEG  F. at 100-1000 p.s.i. are suitable, .04-.08 lbs. AlCl3 per gallon of alkylate being used.  An internal ratio of isoparaffin to olefin of 10-100 to 1 or more is obtained by a high recycle ratio. Specification 596,777 is referred to.

The grip comprises jaws 11 sliding within inclined bores in a member 10 carried by a rod 5, the jaws being biassed to the closed position by a spring 12. The rod 5 is the part subjected to the tension applied to the wire, and carries at the upper end a casing 8 containing the tension indicator 9 which is connected by means of a rod 7 to the lower end of the rod 5. Before tensioning a reinforcement wire 14, extending through concrete 21, a thrust plate 15, a gripper sleeve 17, a pressure tube 18 and a disc 19 are arranged about the wire. The jack carrying an axially movable heavy ring 13 is then positioned above the wire with the wire engaged between the jaws 11. The nut is rotated to raise the ram which engages the casing 8 to lift rod 5 to cause the jaws to grip the wire which is then tensioned by further rotation of the nut. The pressure exerted by the jack and tube on the gripper sleeve during tensioning of this wire causes the gripper sleeve to grip the wire. When the required wire tension is reached the nut rotation is stopped and the disc 19 is struck by the ring 13 to thrust the gripper sleeve into further gripping engagement with the wire. The rotation of the nut is reversed to free the jaws, the jack, pressure tube and disc are removed from the wire, the free end of the wire is cutoff, and the end of the wire is burred over the upper end of the sleeve.
