Title: Improvements in or relating to screw-cutting lathes
IPC: B23Q5/40
Filed: 1953-02-11
Abstract: 738,187. Lathe details. FARROW, B. J. Feb. 1, 1954 [Feb. 11, 1953], No. 3817/53. Class 83(3). Apparatus for use with a screw-cutting lathe having a mandrel 10, Fig. 1, a lead screw 11, a carriage, a device to engage the carriage with the lead screw, and two control elements 45, 59 operatively connected respectively with the mandrel and the lead screw, comprises two contact surfaces 44, 58 for operation by the elements 45, 59 respectively to engage the carriage with the lead screw when the mandrel and the lead screw are in a given relative position. The carriage has an apron 12, Fig. 2, with guideways 16, 17 for a pair of half-nuts 14, 15 connected by a rod 18 and loaded by a spring 20 towards engagement with the lead screw, such engagement normally being prevented by pins 27, 28 mounted on the half-nuts and passing into slots on a disc carried by a lever 23. The half-nuts are permitted to engage the lead screw when the lever 23 is rocked about its pivot 22 by a lever 34 and a cable 36, which is actuated when the contact surface 44 is engaged by the element 45. The surface 44 is formed at one end of a lever 43 pivotally connected at 47 to a plate 48 pivoted at 49 and loaded by a spring 46. This plate is lifted to bring the surface 44 into the path of the element 45 by the element 59 which acts through the contact surface 58. This surface is formed on one end of a member 55 which is displaced by a manually-operated spring-loaded slide 60 when the carriage is to be engaged with the lead screw. A rocking spring-loaded arm mounted on a rail attached to the lathe bed engages a roller 68 and thereby rocks the lever 23 to disengage the carriage from the lead screw at the end of the cut. In a modified construction the lever 23, Fig. 6, is displaced manually by a handle 90 until a stop pin 82 engages a shoulder 84 on a lever 85. During this movement, a pin 79 on the lever 23 displaces a lever 77 which, through the sheath 37 of a cable 36, rocks the member 55 into a position where it will be lifted by the element 59 and thus cause the lever 43 to actuate the cable 36. The latter displaces the lever 85 to permit the lever 23 to continue its movement until the half-nuts engage the lead screw. In this construction, the lever 43 is pivoted at its lower end. In a further modification the lever 77 is pivoted on the lever 85. Specification 737,602 is referred to.

Title: Improvements in or relating to an adjusting system for universal motors
IPC: H02P7/295
Filed: 1967-01-26
Abstract: 1,105,806. Control of D.C. motors. MEFINA S.A. 26 Jan., 1967 [10 Feb., 1966; 10 Nov., 1966], No. 3919/67. Heading H2J. A capacitor C 1  is charged from A.C. terminal b at a rate determined by the adjustment of variable resistor R 2 , which is shunted by fixed resistor R 1 , until Zener diode D 2  breaks down to trigger thyristor T in series with motor M. During the opposite half-cycles of the source a, b, the resistor R 1  only is connected in series with the capacitor C 1 , due to the blocking effect of diode D 1 , and the capacitor is partially discharged. The voltage across capacitor C 2  increases with the motor-current to reduce the discharge rate of the capacitor C 1 , thus decreasing the duration of the next charging period before the diode D 2  breaks down. An increase in motor current thereby advances the instant of ignition of the thyristor T, whereas the ignition-point is delayed if the motor is unloaded. The motor may be connected to a filter network to suppress transients due to switching of the thyristor T which is adapted to be shortcircuited for full-power operation. The diode D 2  may be omitted.
