Filed: 1965-08-17
Abstract: 1,081,528. Centrifugal switches. GENERAL ELECTRIC CO. Aug. 17, 1965, No. 35320/65. Heading H2B. When the rotor 19 of a motor 10 exceeds a predetermined speed, a centrifugal weight assembly 22 carried on the rotor for rotation therewith acts against spring biasing means to displace a portion 27 of a pivotally supported switch actuator 25 such that a portion 29 of the actuator 25, external of the motor casing member 12 supporting rotor shaft 21, causes actuation of a switch 23 mounted externally on casing member 12 via its spring-biased actuating element 24. Springs (40), (41) (Figs. 3, 5, not shown) bias the weight members (37), (38), to hold a push member 39 in an outward position on shaft 21 against portion 27 of switch actuator 25 (Fig. 2, not shown). As the motor 10 starts to rotate, the centrifugal force exerted by weight members (37), (38) overcomes the force of springs (40), (41), and the members (37), (38) displace push member 39 inwardly and allow actuating element 24 to push switch actuator 25 back to its Fig. 1 position. A spring (32) (Fig. 4, not shown) holds portion 29 of actuator 25 against the bearing housing 33 to prevent rattling of the actuator 25.

Abstract: 1,197,295. Refrigerating. CARRIER CORP. 1 Aug., 1967 [2 Sept., 1966]. No. 35343/67. Heading F4H. In a compression-condensation refrigeration system liquid refrigerant passes from a subcooler 13 to the evaporator 5 via a throttle valve 41 which is controlled by a float 34 in a control chamber 31 connected by a pipe 52 to the condenser 3 and by a smaller diameter drain pipe 54 to the evaporator. The condenser end of the pipe 52 is located at a level above the bottom of the condenser and the arrangement of the float and valve is such as to maintain liquid refrigerant at that level and thereby maintain a fully flooded subcooler. The subcooler passes refrigerant to the valve 41 through a pipe 47 and is connected by a pipe 56 to the control chamber. During normal operation a valve 57 in the pipe  56 is closed whereas valves 53 and 55 in the control chamber connections to the condenser and evaporator are open. However during low load conditions valve 55 is closed and valve 57 opened to flood the control chamber and thereby fully open the valve 41 so that liquid refriferant is drained from the condenser to the evaporator and high pressure gas can pass to the  evaporator to agitate the liquid therein. At  start-up, valves 53 and 57 may be closed and valve 55 opened so that the valve 41 closes to  allow a, rapid build-up of high side pressure.

In an automatic feed mechanism for a press or the like, having an oscillating feed arm 14, Fig. 2, with a pick-up head 13 for picking up individual workpieces from a supply point 27 and transferring them to the press die or the like 28, the feed arm is actuated by its own power unit 12, Fig. 1, through a rotating disc 23 Fig. 2, and slide member 26. An electric motor 12, which may be combined with a vacuum pump for supplying vacuum to the pick-up head, is connected by a. belt 18 to a clutch 20 on the input shaft of a gear-box 21 whose output shaft 22 carries a disc 23 with a crank pin 24 connected by a rod 25 to the slide 26 which reciprocates in horizontal guides 29. The slide is connected by a rod 30 and spring-biased lost-motion connection 31 to a lug 32 rigid with a spindle 33 to which is keyed a sleeve 34 connected to the arm 14. The sleeve is slidable vertically and spring-biased upwardly on the spindle 33 and its lower end has a flange 38 engaged by a pair of rollers 39 on a lever 50 pivoted at 51 and carrying a second roller adapted to be engaged alternately by a pair of cams 53, 54 on the slide 26. As the latter reciprocates the arm is oscillated between adjustable stops 36, 37 and upon engagement with these stops the cams 53, 54 actuate the lever 50 to depress the arm 14 and cause the pick-up head to be lowered on to a workpiece or to deposit it in the die. The pick-up head is actuated electromagnetically, hydraulically or pneumatically and in the latter case, Fig. 4, the supply of air pressure or vacuum to the head from either of lines 63, 67 is controlled by a valve 68 actuated by a toggle 71 adapted to be tripped by cams 72, 73 operated from the feed arm 14. A hand control lever 70 selects whether pressure or vacuum shall be supplied to the head or shuts off the supply. A second valve 64 linked to a contactor controlling the feed motor 12, controls the air/vacuum and electrical supply and also provides a by-pass line 66 for the air or vacuum to reach the head and keep it permanently energized during setting of the mechanism, as described in Specification 785,716. A cam 56 on the output shaft of the gear-box actuates a clutch control valve 58 controlling an air motor 60, 61 which actuates the foot pedal 62 controlling the main clutch of the press. A second cam 79 on the output shaft co-operates with a follower 80, 81 connected through a Bowden cable 82 with a cage 83 which covers the starter button 85 of the press motor thus preventing its being started if the feed arm is under the press ram. The feed mechanism may be operated by a handle 77, Fig. 1, during setting. When the head is operated electromagnetically, the valves 64, 68, Fig. 4, are replaced by switches.
