Title: Improvements in packages and a method of preparing a package of material for taking impressions or the like
IPC: B65D77/04
Filed: 1934-10-03
Abstract: 444,908. Packages ; capsules ; collapsable tubes. L. D. CAULK CO., Milford, Delaware, U.S.A. Oct. 3, 1934, No. 28357. Convention date, March 27.

Patent GB-152029-A (GB)
Title: Improvements in the separation of metal from ores
IPC: C22B19/36
Filed: 1920-10-06
Abstract: 152,029. Metals Extraction Corporation of America (Assignees of Schwarz, A.). Oct. 6, 1919, [Convention date]. Zinc and other oxides.-Sulphide, carbonate, silicate or other ores, roasted or not, are mixed with a binder preferably one capable of yielding a coked mass such as starch paste and with or without a reducing agent such as powdered coal, and may be spread upon pieces of refractory material such as slag, for instance by mixing the pasty mixture and the slag pieces in a pug mill. The pieces coated with the paste are placed on a bed of fuel on a grate 2. Air is sucked through the charge by a fan 8 and subsequently air is blown in from a blower 3. The metal is reduced to the metallic state and vaporizes, a separation being thus effected between volatile and less volatile metals, and the fume may be condensed as metal, or an excess of air may be employed to obtain oxide. The invention is described with reference to the production of zinc oxide from zinc ores. Reference has been directed by the Comptroller to Specifications 10915/00, 29156/06, 6888/08, 22519/13, and 112,336.

Title: Removing salts deposits from forced flow, once through steam generators
IPC: F28G9/00
Filed: 1954-10-01
Abstract: 754,994. Forced flow and critical pressure steam boilers. SULZER FRERES SOC. ANON. Oct. 1, 1954 [Oct. 27, 1953], No. 28392/54. Class 123(2). A method of operating a forced flow once-through boiler generating steam at subcritical or supercritical pressure whereby the steam output is maintained during the periods when the conversion zone of the boiler is flushed out to free it from deposited salts comprises by-passing the working medium around the zone to another part of the generator wherein it is converted into steam whilst the flushing is taking place. In one form the generator comprises a pump 1 which feeds water through a preheater 2 into a heat exchanger 4 where conversion into steam takes place, the steam flowing through pipe 5 and 3-way valve 6 to a superheater 7 whence it is led back through pipe 9 to the heat exchanger to heat the incoming water to supercritical temperature. The partly cooled steam leaves the heat exchanger and flows through a pipe 10 to a final superheater 11. When flushing of the heat exchanger becomes necessary, the valve 6 is actuated to permit water to flow directly into the superheater 7 wherein it is evaporated, a valve 12 being opened to allow the steam to by-pass the heat exchanger. A valve 15 in a branch discharge pipe 14 is then opened and part of the heated water from preheater 2 flows through the heat exchanger to dissolve out and carry away the salts deposited therein. In a modification, provision is made for the introduction of a flushing medium from an external source and for an additional heat exchanger 4 connected so that either heat exchanger can be shut off for flushing whilst steam is being generated in the other.

Bottles, jars, and the like, washing.-In a machine in which the bottles 7 are carried in pockets 6 arranged around a wheel 1 which is rotated intermittently within a casing 3 containing cleansing solution, the bottles being discharged by gravity, the introduction and discharge of the bottles take place at the same side of the wheel. In the construction shown, a number of bottles to be soaked are placed on a tray 23 and are fed forwardly through an opening 1<a> in the casing 3 by rollers 11 which are mounted on a shaft 12 and are actuated through the medium of links and levers and a roller 17<a>, by means of a cam 19 on a driven shaft 20. The opening in the casing 3 may be provided with a shutter normally closed when the rollers 11 are in the retracted position and adapted to open when the rollers are being moved forwardly. The bottles are. discharged through an opening 8 normally closed by a pivotally-mounted door 9 which is opened by means including links and levers and a roller 17<b> actuated by a cam 33. The wheel 1 is rotated step-by-step, by means of a wheel 5 formed with recesses 5a for engagement with a crank 4. To hold the wheel against rotation during the feeding and discharge of the bottles, a pivotallymounted spring.pressed lever 36<c> is provided on the machine, the lever having at one end a roller 39 for engagement in a recess in the wheel 5. The lever has a pin-and-slot connection with a rod 38 connected to the crank 4 so that the crank and the roller 39 are alternately in engageemnt with the wheel 5. To the inside of the wheel 1 are secured buckets 27 adapted' to pick up liquid with labels and other foreign matter and discharge it to a gutter 28, which delivers to a rotary filtering drum 31a, the liquid being returned to the casing by a pipe 32.

The transformer core is a temperature-sensitive ferrite whose permeability changes abruptly at 70 C. Exciting windings 1 of the motor are connected between a D.C. supply 22 and the driver circuits 3 which are fed from an oscillator 16 via the transformer 15 and detecting coils 17, the detecting coils being angularly spaced at 120 degrees apart and excited by a marker magnet extending over an angle of 120 degrees on the rotor to give an indication of the rotary position of the rotor to control the current supply to the motor. The motor has a stator 21 supported on a base 20 and surrounded by a cupshaped rotor 22 on a shaft 19, the rotor carrying permanent magnets 23. The marker magnet is made of magnetic rubber.

As shown, the non-metallic frame consists of a bridge 10 connecting eye-frames 11, 12 provided with hinge lugs 13, 14. The reinforcement consists of a wire 15 embedded in the bridge and having its ends welded &c. to frames 16, 17 embedded in grooves in the frames 11, 12 and themselves formed with grooves to receive the lenses. The reinforcing frames 16, 17 are split at 19 and 20 so that when the frames 11, 12 are softened by heating, the frames 16, 17 can be sprung for inserting the lenses. Preferably the bridge 10 is formed with a groove 21 to receive the wire 15, this groove being afterwards filled. Alternatively the wire 15, to which one of the frames 16, 17 may be previously secured, may be passed through a hole drilled through the bridge.

Abstract: 1364256 Dual control vehicles INTERNATIONAL HARVESTER CO 22 June 1971 [6 July 1970] 29191/71 Heading B7H [Also in Division F2] A control circuit for a vehicle having front and rear driver stations 10, 12 and engines includes throttle and brake control valves 28, 36 and 26, 38 at each station and a selector valve 14 for connecting the valves of one station to a fluid pressure, preferably pneumatic, source 18, the arrangement being such that the brakes and either engine may be operated solely from either one of the stations. In a first position valve 14 connects valve 26, 28 to source 18 and exhausts lines 30, 32, 34 to valves 36, 38. With brake pedal 84 as shown fluid passes via lines 22, 42, check valve 46, which isolates the rear station brake valve, and line 48 to a cylinder 50 containing a spring-loaded piston 58, the fluid urging the piston against a spring 76 to release the braking means 72. Depression of the brake pedal 84 moves valve 26 to cut off fluid supply and exhaust line 42. Throttle valve 28 normally blocks fluid passage from source 18 to line 88, but depression thereof connects lines 24, 88 and fluid passes to a check valve 92, which isolates the second station, and through lines 102, 104, solenoid valves 106, 108 to cylinders 114 and 116. Pistons 118, 120 in cylinders 114, 116 are normally biased by springs 130, 132 to the idling piston, pistons 118, 120 being connected to engine speed controls 126, 128. Switches 138, 140, respectively for the front and rear engines are switched on in sequence. On turning switch 138 to the start position lines 146, 150 are actuated to operate solenoid 148 and ignition 152, solenoid 148 moving valve 108 to isolate line 112 from line 104 to prevent flooding of the rear engine whilst the front engine is started. Manual switch 158 in line 154 to the starter motor 156 is closed and then switch 138 is moved to the run position wherein solenoid 148 is deactivated and valve 108 reopened. Switch 140 is then operated to start the rear engine, during which valve 106 is closed in the same way as valve 108. With valves 108 and 106 closed fluid remains trapped in lines 110, 112, however, in a further embodiment (Fig. 2, not shown) these valves are provided with exhaust paths to allow fluid to leave cylinders 114, 116 whilst the valves are closed.
