Abstract: 1,015,725. Molecular fractionating stills. VITAMINS Ltd. Feb. 18, 1963 [March 1, 1962], No. 8059/62. Heading BIB. In a molecular fractionating still comprising a stationary evaporator surface 26 surrounding a stationary condenser surface 10, a wiping and transfer assembly is mounted to rotate between the two surfaces, the assembly comprising elements 68 which wipe both surfaces and transfer condensate from the condenser surface to the evaporator surface through upwardly inclined channels 114. The evaporator may be in the form of an upright doublewalled cylinder divided into two heating jackets. The lower jacket is maintained at a higher temperature than the upper one. The liquid to be fractionated is fed into an annular gutter and flows through channels between the two jackets to the hot inner wall of the cylinder, where it is spread over the surface 26 as a film by the wipers 108 carried by elements 68. Evaporation of the more volatile components of the liquid film occurs, and the vapour formed condenses on the condenser surface 10. The flexible scraper blade 110 of each element 68 removes the condensate from surface 10 and transfers it, via channels 114, to a higher level on surface 26, where it is redistributed as a film and re-evaporated. The final distillate is withdrawn from the top of surface 10. The residual liquid flows off the base of surface 26. The angle of ducts 114 can be altered to control the rate of fractionation of the liquid in the still.

Patent GB-580264-A (GB)
Title: Improvements in hand-operated, automatically tripped, electric switch mechanisms
IPC: H01H71/52
Filed: 1944-05-03
Abstract: 580,264. Retractive switches; snap-action switches; electrically-tripped switches. JACK & HEINTZ, Inc. May 3, 1944, No. 8374. Convention date, Feb. 18, 1943. [Class 38 (v)] A switch for a motor 2, particularly in an energizer for an aircraft inertia starter, is moved "on" and "off" by gripping and releasing a hand grip 5 and may also, while the lever 5 is gripped, be tripped to open by overspeed or overload device. When the hand grip 5 is pressed to the handle 3 against a spring 9 the switch is moved from the open position, Fig. 3, by a link 8 causing an arm 7 to rotate clockwise about a fixed pivot 39, carrying with it two members 42, 43 pivoted to the arm 7 at 40, 41. Clockwise rotation of the member 42 carries over dead-centre a spring 47 pivoted at a notch 49 in a yoke 46 having a fixed pivot 45 and carrying contact arms 37, 38 bridging fixed contacts 32, 33, to complete the motor circuit. On excessive speed of the motor, a governor 6 causes an operating plunger 10 to move a lever 11 to trip a detent 51 by upward pressure on a T-head 64 on this detent. When the detent 51 is raised the member 43 is released and swings clockwise, uncoupling a hook 52 and a projection 53 and enabling the member 42 to move counter-clockwise under action of the spring 47, which, passing the dead-centre line 49, 45, opens the switch, Fig. 5 (not shown). Similarly, the detent 51 may be tripped on overload by a bimetallic strip 61 heated by a heater 60 in the motor circuit and acting on the other side of the T-head 64. The switch is reclosed by releasing the grip 5 and then squeezing it again, but will not reclose until the lever 11 and strip 61 permit the detent 51 to re-engage the member 43. The switch mechanism may form a self-contained unit, enclosed in an insulating box with an aperture over the lever 11 for entry of the plunger 10, the complete unit being removable on disconnection of the lever 8.

Patent GB-548432-A (GB)
Title: Improvements in or relating to machines employed in screwcutting operations
IPC: B23G1/16
Filed: 1941-07-07
Abstract: 548,432. Tapping &c. machines. HAYWARD, C. July 7, 1941, No. 8536. [Class 83 (iii)] In a tapping or like screwcutting machine in which the spindle is driven by a reversing motor, means are provided so that in the event of the tool meeting abnormal resistance the direction of rotation is first released to relieve the resistance and is then restored to normal forward operation. In the form in which the spindle 2, Fig. 2, is fed by a lead screw 13 resiliently mounted thereon and engaging a fixed nut 12, the nut is splined in the framing and has a recess to receive a cam-ended spring plunger 18. When the yielding drive chuck 17 stops, the consequent resistance of the feed causes the nut to rise, camming back the plunger 18 and actuating a switch 11. Tappets 6, 7 control switches 9, 10 for reversal in ordinary running. Solenoids 38, 39, Fig. 3, close switches for forward and reverse running respectively; the switch 9 controls a normally closed contact 9c and normally open contact 9b the switch 10 controls a normally closed contact 10 ; the switch 11 controls a normally closed contact 11a and normally open contact 11b. In operation, a starting switch 37 is closed completing a circuit through the coil 38. At the end of the down feed a tappet 7 operates the switch 9, breaking the forward circuit at 9a and closing the return circuit at 9b and establishing a holding circuit 41. As the spindle returns and the tappet 7 leaves the switch 9 the latter returns to the forward running position but the reverse motion continues due to the holding switch 41 ; the two double mechanisms 38, 39 being interlocked so that one only can be operative at a time. At the end of the return stroke tappet 6 operates the switch 10, opening the contact 41 and throwing out the switch 39 ; the switch 38 then becomes operative and the motor runs in the forward direction again. When the switch 11 comes into operation the forward circuit is broken at 11a and the reverse circuit is closed at 11b but in this case the holding contact 41 is not closed. As soon as the nut reseats, 11b opens and 11 closes again and forward drive is resumed. In a modification and to ensure restart in the forward direction after operation of the switch 11 and without having to return the spindle to the top of its stroke, a sleeve 22 enclosing a flange on the lead screw carries a rod 23. Movement of the nut actuates the switch 11 through an interposed bell-crank 25 and lifting of the arm 26 permits a spring-pressed roller 27 to rise in a taper recess 29 and lock the rod 23 and consequently the spindle against upward movement thereby securing a prompt reseating of the nut 12. In a further modification for machines in which the spindle quill is fed by rack and pinion, the connection between the pinion and its shaft is by means of a cross pin on the shaft engaging an inclined notch in the pinion boss. Abnormal resistance carries the pinion-shaft axially to actuate the switch 11.
