Abstract: 812,006. Typewriters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 20, 1955 [Dec. 29, 1954], No. 36434/55. Class 100(4) In a typewriter or like machine having a carriage capable of free forward movement and/or power-driven return movement and means for decelerating the carriage after such movement, the decelerating means comprise movable check means engageable by a co-operating stop associated with the carriage at a predetermined distance from the end of such movement thereof, and permits continued movement of the carriage at progressively decreasing speed. Margin rack 2 is movable with the carriage and when the latter returns shoulder 16 of the margin stop 4 engages shoulder 18 of margin control lever 8 sliding the latter to a limit determined by slots 9 and studs 10. This movement of lever 8 rotates bell-crank 12 counter-clockwise which rocks 68, 66 and through 64, and adjustable extension 62 rocks arm 56 counterclockwise to engage roll 60 with cam 48. Spring 72 tends to rotate cam 48 counterclockwise and in any steady state position disengages clutch 52 so that the continuously rotating shaft 46 rotates free of. cam 48. but when roll 60 tends to move cam 48 clockwise the clutch is engaged so that the cam turns with shaft 46. The cam has the form of a decelerating curve which by controlling the movement of arm 56 slows the movement of the carriage at a predetermined rate. The decelerator on the tabulator run opeiates oppositely to the carriage return decelerator. Operation of the tabulator power device rocks bell crank 24 which pivots tabulating lever 20 about axis 22 so that check lever 30 is pushed from behind shoulder 32 and freed for movement to the left, to a limit determined by slots 33, by a spring 36 acting through 42, 38, 34. Spring 90 tends to rotate cam 50 counterclockwise to a position similar to that of cam 48 in Fig. 1. As the carriage moves to the right, Fig. 1, lever 30 engages a tabulating stop and is moved to the right to the limit position shown in Fig. 1. During this movement lever 30 acts through 34, 38, 88 and 86 to rotate arm 82 counterclockwise pressing roll 80 against cam 50 so as to engage clutch 54. Cam 50 thus controls the speed of the tabulating operation of the carriage until lever 30 reaches its Fig. 1 position, when members 38, 82 assume a steady state position and spring 90 releases clutch 54. Specification 806,053 is referred to.

Abstract: 782,374. Automatic temperature control. CRACK, K. G. Dec. 20, 1955 [Dec. 21, 1954], No. 36952/54. Class 38 (4). The heater supply in an electrical heating system is cut off by a time switch during predetermined periods and, therebetween, is controlled by a thermostat, the temperature setting of which is gradually increased at least for part of the time. In one embodiment, the control contacts of a mechanical thermostat 23, Figs. 2, 3, and a time switch 10 are in series in the supply lead to the heater. The'temperature-setting knob 22 of the thermostat is operated by rotation of a spindle 19 carrying a pinion 18 engaged by a rack 17 attached to an arm 14. The position of the latter is controlled by the clock of the time switch which drives a disc 12 which has a grooved cam track 13 in which engages a cam follower on the arm 14. The cam may be arranged to gradually decrease the thermostat setting during the cut-off periods or to rapidly decrease the setting at the beginning of such periods. The rack 17 is held in engagement with the pinion 18 by a guide roller 24 on a spindle 25 which for adjustment purposes may be lifted by a pin 26, turned and dropped so that pin 26 passes down a slot 27. The pinion 18 can then be disengaged from the rack 17 by lifting the spindle 19 so that the spring plunger 28 engages a groove 29 in the spindle instead of a groove 30. In another embodiment, the thermostat comprises a bridge circuit with a temperature-sensitive arm and a variable temperature-setting resistance controlled by a cam, as in the first embodiment, Fig. 5 (not shown) or directly by the clock spindle, Fig. 7 (not shown). In the latter case, the relationship between the value of the resistance and the angular setting of its control spindle is arranged to give the required relationship between time and temperature setting. The bridge circuit comprises the temperaturesensitive resistor 50, Fig. 9, the resistors 51, 52, 56 and the variable temperature-setting resistance 67. The D.C. current for the bridge is supplied to one diagonal from the rectifier 65 fed from the A.C. mains 40, 41 through transformer 64, 75. When the bridge is unbalanced in one direction, a relay 68, connected across the other diagonal, operates contacts 69 to energize relay 73 and close contact 74 connecting the heater circuit 43, 44 to the supply 40, 41. At the same time the current of relay 73 flows through resistance 80 connected in the bridge unbalancing it further to increase the operating current of relay 68.

Abstract: 982,231. Rolling. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 20, 1963 [Sept. 21, 1962; April 29, 1963], No. 37076/63. Heading B3M. [Also in Division G3] A method of controlling the cross-section shape of a workpiece which is passed through one or more pairs of crowned rolls comprises predicting the pass screwdown setting for each pair of rolls, according to the desired incoming and delivery thickness of the workpiece and the mill characteristics, and passing the workpiece through the rolls when so positioned. For single stand reversing rolling, Fig. 1, thickness gauges 31 and 34, width gauges 35 and 33 and temperature gauges 36 measure parameters of a strip 32 and feed values to a computer 24. Information, such as roll speed frame 39, roll force frame 37, and roll position frame 28, the workpiece composition, desired delivery thickness from each pass and initial workpiece temperature is also fed to the computer, and a motor speed control 22 for the work rolls 12 and 14, and a screwdown position control 28 are actuated by the computer to control the rolling operation. Similarly, for a tandem rolling mill, Fig. 2, interstand computers 68 and 78 and a central computer 72 are fed with information from speed sensers 64 and 82, thickness gauges 58 and 74, temperature gauges 60 and 76 and an overriding X-ray thickness gauge 56 situated after the last stand, in order that the strip cross-section can be controlled. It is preferred that the final strip content be slightly thicker in its centre than at its edges in order to give it more stability whilst being rolled. Independent control of the serewdown mechanism at both ends of the rolls of a stand is possible, a number of gauges measuring the strip thickness across its width. Specification 982,232 is referred to.
