Title: Improvements in firing boilers
Inventor: MOSS GERALD
IPC: F23K5/00
Filed: 1961-10-11
Abstract: 966,579. Preventing furnace corrosion; supplying liquid fuel to burners. ESSO RESEARCH & ENGINEERING CO. Aug. 21, 1962 [Oct. 11, 1961], No. 36488/61. Headings F4B and F4T. A method of supplying liquid fuel to the burners of the superheater of a boiler comprises passing fuel from a source into a splitter 6, directing a portion of the fuel through one or more cracking coils 4, then quenching the directed portion with the fuel from the source in the splitter 6 and passing separated overheads from the splitter to the superheater burners. The fuel in the cracking coils is partially broken down into a product which is substantially free from vanadium and sodium. The overheads are superheated and led to the burners in vapour form. Part of the overheads is fed through a valve 11 to a main furnace balancing burner. Part of the bottoms is led through a valve 15 to the main boiler. The fuel is supplied by a pump 2 from the source. The bottoms are fed by a pump 13. Threeway valves 7 enable a selected cracking coil 4 to be purged by steam and air without interrupting the flow of fuel through the remaining coils.

Title: Improvements in or relating to electric remote control arrangements for transmitting a plurality of control signals or connections
IPC: B60L15/32
Filed: 1954-12-23
Abstract: 765,503. Electric selective signalling systems. ZAHNRADFABRIK FRIEDRICHSHAFEN AKT.-GES. Dec. 23, 1954 [Jan. 20, 1954], No. 37278/54. Class 40 (1). An electric remote control system for the transmission of a plurality of control signals comprises a bridge circuit including voltage dependent resistors 10 and normal resistors 11, Fig. 1. Resistors 11 alternatively may have a characteristic opposed to that of resistors 10. A relay 8 is connected across the bridge, and a D.C. potential is applied to the bridge via leads 4, 5. Resistors 6 are connected across the D.C. supply, and by means of the control switch 3 the voltage may be increased or decreased, and the polarity reversed. The relay contact 9 is normally in its neutral position. With the switch 3 on contact I the resistances 10 are small in relation to the resistance 11 and the relay 8 is energized in one direction to move contact 9 to the left and energize relay 12 to make contact I of relay 12 and provide a control signal. With switch 3 on contact II the voltage is reduced but is of the same polarity. Resistances 10 now are high in relation to resistances 11 and the relay 8 is energized in the opposite direction to energize relay 13 and make contact II of relay 13, giving a second control signal. If arm 3 is on contact III the voltage is the same as on contact II but with reversed polarity. The relay 8 is reversed and energizes relay 12 but with reversed polarity, thus making contact III of relay 12. Similarly, with switch 3 on contact IV the voltage rises again and contact IV of relay 13 is connected. In an alternative arrangement, Fig. 2, an additional relay 25 is included for switching in an auxiliary D.C. supply to the relays 15, 16, 17, 18, which are single acting and are connected to the switch contacts of the bridge relay 8 through appropriately poled rectifiers 20, 21. In a further arrangement, Fig. 3 (not shown), two bridge circuits are used whereby any one of six control lines may be energized one bridge circuit being fed through a full-wave rectifier so that its relay responds only to a voltage increase.

Title: Improvements in electric vacuum switch apparatus
IPC: H01H33/666
Filed: 1929-12-05
Abstract: 348,555. High vacuum ejector apparatus. CALIFORNIA INSTITUTE OF TECHNOLOGY, 1201, East California Street, Pasadena, California, U.S.A. Dec. 5, 1929, No. 37361. Convention date, Dec. 26, 1928. [Class 71.] High-tension switches consisting of highlyevacuated containers 4 with electrodes 26 operated by external means through flexible bellows 24 constituting part of the container have similar bellows 5, 6 at each end of the container so that it is resiliently supported, and the container is permanently connected with pumping means to maintain the vacuum automatically. The pipe 44 to the pump is connected to a sleeve 20 located between the two flexible connections 6, 24 so the pipe itself has a flexible union with the container. The line pipes connect to a common exhaust pipe 46 connecting through gas traps with the condenser 54 of a vacuum pump 52 of the mercury-still type. When the vacuum falls, a three-electrode thermionic valve 63 in the common exhaust pipe (functioning as a pressure gauge) allows a relay 68 to close thereby energizing the heating coil 59 of the mercury pump and initiating the evacuating process which is maintained automatically until the required degree of vacuum is reached. A vacuum reservoir 57 is provided also in association with the mercury pump and is connected with a rotary pump 56 put into action when the pressure in 57 falls by the pressure contact gauge 58. Mercury vapour traps 47 (surrounded by liquid air) and 48 (internally coated with metallic sodium) are employed.

A machine for spirally winding a bead core from a ribbon 15 of rubberized parallel wires, prior to side-lap splicing the inner terminal end 39 of the ribbon in a press such as disclosed in Specification 841,880, comprises a rotatable former 11 having a cylindrical peripheral winding surface with an opening 32 therein which intersects the winding surface in an acute angle to form a knife edge 34, the inner terminal end 39 of the ribbon being received and releasably gripped in said opening at a substantial inward spacing from the winding surface and being supported on a radially outwardly facing surface 36 of said opening, and said surface 36 being radially inset immediately adjacent the knife edge 34 so that the ribbon end 39 is unsupported immediately inward of the knife edge whereby, on tensioning of the ribbon during winding, a permanent inward set is imparted to the terminal end 39 so that it remains free of the inner convolution of the wound core. As shown, the former comprises major and minor chordal segments 19, 18 pivotally connected on a pin 22 and urged together by a spring 28, the opening 32 being formed in the segment 19 to merge into the split between the segments, and to lie opposite a recess 25 in the segment 18. A gripper insert 35 is bolted to the segment 19 to provide the supporting surface 36 with the radially inset end 38, the insert having guide flanges 41, 42 radially upstanding from the surface 36, and pivotally carrying a pair of gripper arms 44, 45. The arms 44, 45 mount between them a gripper pin 43 and a roller 48, and are biased by a spring 49 so that the pin 43 clamps the ribbon end 39 on to the surface 36 and the roller 48 cams against the underside of the recess 25 to spread the segments 18, 19 into operative winding position. A cam-operated link 51 is operable to overcome the spring 49 to release the ribbon end and collapse the segments on completion of the core winding ready for ejection by fingers 68. During winding of the core an adjustable spring-loaded roller 59 presses against the outermost convolution to consolidate the core. Specification 802,253 also is referred to.

Title: Size measuring device for workpiece of noncircular cross-section

Filed: 1972-08-17
Abstract: 1396747 Grinding TOYODA KOKI KK 17 Aug 1972 [20 Aug 1971] 38448/72 Heading B3D [Also in Division G1] The diameter of a workpiece 10, Fig. 1, is measured electrically as it is ground by wheel 11; the diameter is compared with a preset value and the grinding operation is stopped when this value is achieved. In Fig. 1, the workpiece has an elliptical cross-section and its size is measured by diametrically opposed arms 16, 17 of differential transformer 15. As the ellipse is rotated during grinding a cyclic signal is given by the transformer as arms 16, 17 are moved to and fro. The signal is amplified and passed to a synchronous rectifier. The peak value of the rectifier output is stored in capacitor C 1  of holding circuit 34; a circuit 36 analyses the rectifier output and gives a first signal as the cyclic signal passes from minimum to maximum and a second signal as the cyclic signal falls again to its minimum. These two signals respectively discharge C 1  and gate the voltage on C 1  through an FET in a sampling circuit 35 to capacitor C 2 . The result of this is that the peak value of the cyclic signal, which represents the ellipse major diameter is passed from detector circuit 34 to sample circuit 35 under control of the timing circuit 36. When the output of sample circuit 35 reaches a predetermined value a Schmitt circuit 38 is triggered and relay 29 stops the grinding operation.
