Title: Improvements in or relating to machine tools
IPC: B23Q5/28
Filed: 1956-12-28
Abstract: 876,478. Milling. VICTORIA MACHINE TOOL CO. Ltd., FRYE, J., and GRONAU, H. Dec. 23, 1957 [Dec. 28, 1956], No. 39441/56. Class 83 (3). Apparatus for controlling the feed-table 2 of a machine tool comprises a control element 7 which, in its movement, starts the motor 3 with a change-speed transmission 4 set for rapid traverse, alters the speed to feed and finally reverses the motor and resets the transmission to rapid traverse. The table 2 moves on a saddle 1 adjustable bv a handlever 67. The motor 3, gear-box 4 and a switchbox 5 are attached to a standard knee-type milling machine. To operate the change-speed gearing, the lever 7 rocks a lever 10, Fig. 4, linked to a rack-toothed rod 12 which rotates pinions 13, 15 on a rod 14 to cause a rod 16, Fig. 13, to move up or down. The rod 16 rocks a lever 17 to move a block 19 axially, causing a spring 23 to be compressed. Towards the end of its movement, an arm 27 on the lever releases a catch 25 allowing a block 21 fastened to a rod 20 to snap upwards. Movement of the lever 7 in the opposite direction snaps the rod 20 downwards, the rod 20 being connected by a yoke to a double dog-clutch on a feed-shaft. The clutch connects a feed or rapid traverse drive to a bevel gear 68, Fig. 4, engaging a gear 69 which can be clutched to the feed screw 70 by a lever 64 controlling a clutch 71. The screw is connected to the table and rotates in fixed nuts 72, 73 associated with a back-lash adjusting device 74. A lever 66 on the gear-box 4 controls a sliding gear and clutch member for providing two feed speeds. When the lever 7 is rocked, it causes a cam 58 to operate a switch RM or LM which sets a circuit for energizing the motor 3, the motor being started when a second switch is operated by a cam on the rod 14. The sequence of table movement is as stated above either to left or right, or alternatively to left and right continuously according to the setting of a selector switch. In a cycle of movement to the right, the selector switch is set for rightward movement and the control lever 7 is moved to the right. Fast traverse ensues until a dog FRD on the table strikes a projection 60 on the lever 7 to centralize it. The table then travels at feed speed until a second dog QLD strikes the projection, moves the lever 7 to the left and causes rapid return movement. The cycle is completed when a dog CSD actuates a cycle stop switch CS. Setting the selector switch for leftward movement and moving the lever 7 to the left gives a similar cycle to the left. A third position of the selector switch is for pendulum movement. The table starts to move in whichever direction the lever 7 is set, as soon as a " pendulum " push-button is depressed. A leftward or rightward cycle will cease when the table is again central unless the " pendulum " push-button is again pressed.

Patent GB-1510663-A (GB)
Title: Method of and apparatus for adjusting electrical chokes
IPC: H01F41/00
Filed: 1975-09-29
Abstract: The method allows iron-core inductors to be produced with an inductance which is subject to tight tolerances. The adjustment (trimming) which is required for this purpose has been carried out, in the case of inductors having two core stacks which can be displaced with respect to one another within tight limits, with the aid of a pressure-loaded roller by means of which the core stacks were displaced with respect to one another on a sufficient part of the length of the inductor, and the air gap was thus reduced. This adjusting (trimming) principle is now used in conjunction with an inductor (6) having an E/I-shaped jacket core in that the I-shaped stack is permanently bent on a part of its length. <IMAGE>

Title: A process for the removal of water from steam-stripped liquid hydrocarbon oil distillates
IPC: C10G7/00
Filed: 1957-12-24
Abstract: Steam-stripped liquid hydrocarbon distillates boiling in the range 150-400 DEG C. are dried by introducing the moist distillate into a liquid/vapour separation zone where it is maintained for at least 30 seconds as a relatively thin layer of less than 12 cms. in depth, removing resultant vapours comprising water and lighter hydrocarbons, condensing these and separating the two layers formed, returning the hydrocarbon layer to the liquid/vapour separation zone and discarding the water and recovering the dried hydrocarbon distillate.  The temperature of the distillate should preferably be within the lower half of its boiling range and conditions are such that 1-5% by weight of the distillate is removed as vapours.  A slight vacuum is maintained by the condensation of the vapours but a further slight vacuum can be induced.  The water content is reduced from 0.06-0.1% to 0.005-0.01% by weight.

[Also in Division G6] A system for braking a movable mass 1 comprises a guide element 2 and a braking part 6, rubbing members 10 for engaging the braking part, first resilient means 12 to urge the rubbing members into contact with the braking part and second resilient means 14 by which the rubbing members are coupled to the mass, the second resilient means, upon relative movement of the mass and the rubbing members induced by engagement of the latter with the braking part, being compressed to provide a further loading of the rubbing members on to the braking part. As shown the moving mass comprises e.g. a cylindrical control rod 1 movable at high speed in a nuclear reactor core 3, and the guide element comprises a rigid rod 2 which is secured to a stationary structure 3 and which has an upper zone 4, which allows unimpeded movement of the control rod 1, a wider lower braking zone 6, and a frusto-conical transition zone 7. The brake is housed in a easing 8 carried by the lower end of the control rod and includes braking elements in the form of cylindrical sectors 10 disposed around the rod 2. The sectors 10 are connected, adjacent their upper ends, by circlips 12, a stack 14 of ring springs 18, 19 with coacting conical surfaces being interposed between shoulders 16 on the lower ends of the sectors 10 and the base 15 of the control rod 1. The rings 18 are continuous, the rings 19 being split at 20. When the control rod 1 falls the brake sectors 10 pass freely over the upper zone 4 of the rod 2 to impinge upon the transition zone 7 and slow down the control rod 1. The momentum of the control rod 1 then imposes an axial compression force upon the stack of springs 18, 19, the rings 19 being radially contracted to force the sectors 10 into heavy clamping engagement with the lower zone 6, of the rod 2 so that the control rod is stopped rapidly. It is stated that braking forces, varying between 1 ton and 4 tons, or even more, have proved possible. The system could also be used with a mass driven, e.g. by an explosive charge, along a horizontal passage. In a modification the system may be used to brake a solid cylindrical mass in a hollow cylindrical guide element.
