Abstract: 919,866. Servicing reactors. GENERAL ELECTRIC CO. Ltd. Aug. 28, 1961 [Sept. 2, 1960], No. 30342/60. Class 39 (4). A servicing machine for connection to a reactor standpipe and operating whilst the reactor is on load comprises a pressure vessel housing a rotatable turret on which are mounted a plurality of servicing mechanisms including a fuel element magazine, stowage devices for control rod assemblies and grebs for engaging fuel elements and control rod assemblies. The machine also includes means for indexing the turret to bring each of the servicing mechanisms to an operating position. As shown, the pressure vessel 1 houses two compartments 2, 3 for control rod assemblies, the compartment 2 being at the operating position. Latches 5 pivoted at 6 at the upper end of each compartment project through apertures 7 into the compartment to engage a control rod assembly stowed therein. An extension 8 on one of the latches carries a roller 9 which normally engages a rail 11 on the vessel 1 to prevent operation of the latches except when the compartment is in the operating position, the latches 5 being connected together for synchronous movement by a rotatable ring segment 12 carrying rollers 13 engaging slots 14 in the latches. As shown, the roller 9 may enter a slot 10 so that the latches may be actuated by a crank 18 pivoted at 19 and carrying rollers 20, 21 for engaging a latch. The crank is operated by a push-rod 15 actuated by a pair of pneumatic cylinders 17.

Title: Improvements in electrical switches
IPC: H01H9/34
Filed: 1923-12-10
Abstract: 228,670. Cox, H. W. Dec. 10, 1923. Switches, quick - action; contacts; sparking, preventing.-In a switch of the kind wherein a series of contacts are arranged on a base and blades oscillating about a common axis connect up pairs thereof, a series of contacts is located in independent compartments in one or more blocks of insulating material, the upper part of which forms a cover and has restricted openings to admit the contact blades, and an insulating cylinder carries the blades which are embedded therein so as to leave free ends which pass through the restricted openings and engage the fixed contacts. As shown in Figs. 1-3, an insulating base A has a cover B and provides a compartment C for each of four contacts D. The cover has restricted openings C<1> to admit the movable contact blades E which are fitted in slots K<1> in an insulating rotary cylinder K arranged so as to close up the open sides of the compartments C. The contacts D are attached to blocks G secured by screws H so as to be loose and self-aligning. The recesses E<2> may be filled with an insulating material which is inserted in a plastic state, and the cylinder ends have metal covers having journals which are mounted in bearings in the ends of the casing M. The cylinder may be of two or more short lengths secured by bolts. A quick-action mechanism comprises a pin R on the cylinder projecting through a slot S in the casing end M and through a slot P<2> in the handle P pivoted at P<1>. This pin R is connected by a dead-centre spring Q with the end of the handle, the edges of the slot P<2> engage the pin R and move it over the dead-centre. In a change-over switch a set of contacts is aranged on either side of the cylinder which is moved from an intermediate position into engagement with either set. Fig. 5 shows a quick-action mechanism for this purpose. The cylinder K has a large journal K<2> fitted with a spring bolt T and arm U, the bolt engaging notches M<1> in the bearing, and the arm U being connected to a rotary actuating-member V by means of two springs W located in the member V. When the latter is moved angularly, one spring W is compressed till one of two cams V<1> formed on the member V engages the bolt and moves it from its notch M<1>, the compressed spring then giving a quick-action. In Fig. 7 the cylinder is in two parts and the blades are carried straight through it. The base A also, in this construction, has openings for the passage of the blades E and a quick-action mechanism such as is shown in Fig. 2 may be employed.

Title: Method of producing low boiling point oil from a relatively higher boiling point oil or fraction
Filed: 1921-11-21
Abstract: 195,422. Hanna, R. W. Nov. 21, 1921. Hydrocarbons, cracking; separate heater and evaporator apparatus.-In cracking petroleum oils or distillates to produce low boiling-point hydrocarbons, deposits of carbon, &c. are prevented by effecting the cracking in presence of an oil which is practically unaffected at the temperature and pressure used, and which keeps the carbon, tarry bodies &c. in suspension or solution. The solvent oil and oils to be cracked are forced together by pumps 2, 13 from tanks 1, 12 along a pipe 3, and discharged into the vapour outlet pipe 16 of an evaporator 5. The liquid falls into a pan 25 from which it passes by a pipe 26 to a T-shaped pipe 27 connected to the outlet pipe 7. The mixture is continuously circulated from the evaporator 5 by a pump 6 through a heater 9. Vapours pass from the evaporator through a dephlegmator 17 and condenser 18. Pressure is retained in the apparatus by a valve 20. The residual oil consisting of the solvent oil and tarry residues &c. is withdrawn from the evaporator through a cooler 22. The cracking may be effected under a pressure of 105-200 lb. per sq. in. and at a temperature of 745-800‹ F. As solvent oil, a distillate from refractorv Californian crude oil may be employed, or, where the oil to be cracked contains or produces a stable fraction, this fraction will serve as solvent oil, additional solvent oil being added to maintain a sufficient proportion.

A chassis assembly includes angle members, each limb of which has a row of equally spaced holes, alternate holes being anular, and of diameter equal to that of the core diameter of self tapping screws, by means of which the chassis parts are held together, the remaining holes being a clearance size for the screws. In the embodiment described angle members (for example 3), in which the clearance holes are of slot form are used to construct two rectangular frames one of which is horizontal and carries circuit elements and the other mounted at an angle to the first and carries control knobs &c. The frames are joined together by means of plates 5 (Fig. 2) having rows of holes 6 to 11 adjacent to the edges; the rows 8 to 11 being curved so that the frames may be mounted at any of a number of angular displacements relative to one another. A chassis plate 16 (Fig. 3), which may carry a printed circuit, is secured to the horizontal frame by means of rectangular section plastic strips 17 (for example polyethylene) having two perpendicular slots. The vertical slots fit over the vertical edges of the frame angle members 12, 13 and the chassis plate is inserted between two opposed horizontal slots. Variable potentiometers and the like may be attached to the second frame by rectangular plates 18 (Fig. 4) having two different size overlapping holes 19, 20 which take the threaded bushes. Three parallel rows of holes are also drilled along the top and bottom of the plates to enable either of the holes 19, 20 to be positioned midway between the runners 14, 15. Pulley wheels 23 of a cord driven control may also be mounted by means of brackets 21, a tubular rivet 24 being fitted over a projection 25 on each bracket to carry the wheel which is secured in place by opening out the V-notch of the projection. In order to prevent the bracket from rotating about its fixing screw, projections 22 are cut to engage with the member 14.
