IPC: B26D1/143
Filed: 1920-03-06
Abstract: 164,146. Day, C. H., (trading as British Automatic Bacon Slicer Co.). March 6, 1920. Cutting slices in succession. - In a disc-knife reciprocating-table slicing- machine, the table is operated by a friction drive to minimize damage to the knife when it contacts with a hard substance. The table g is reciprocated by a connecting - rod 8 and a pin 14 mounted on the disc 10 which derives motion, through bevel gearing 16, 17 and spring-pressed friction blocks 19, from the main shaft r. The disc 10 and gear wheel 16 are loosely mounted on the headed spindle 11, the springs 20 arc adjusted by nuts 21, and the surface of the wheel 16 or the blocks 19 may be faced with leather. The blocks 19 and springs 20 are carried by studs 18 which are secured to the disc 10. The foodstuff is clamped by members s, t to a table h which is mounted on the table g and is fed toward the knife by a screw shaft : i which is intermittently operated by ratchet gear, Fig. 4. The shaft i, carried in brackets k on the table g, co-operates with a half nut which is carried by a bracket on the table h and is engaged or disengaged from the screw shaft i by a cam-ended pivoted lever. The ratchet wheel is provided with a handle and is operated on the return motion of the table g, by a pawl 38 and a cranked lever 35, provided with a returning-spring 37 and a roller 36 which contacts with a stationary vertically adjustable cam 40. A longitudinally adjustable bar 23, having an enlarged end 31 which bears against the lever 65, is secured by set-screws to the table g and is retained in definite positions by the engagement of one of the set-screws with one of a series of notches in the bar 23. The period of contact of the roller 36 with the cam 40, and consequently the slice thickness, is thus varied as desired. The knife is driven by the usual gearing and chain and sprocket wheel; and the table g is mounted on longitudinal rails which are supported by pillars on the base-plate a, the rails being engage'd on the underside by the roller brackets in order that tipping of the table may be prevented.

Title: Process of and apparatus for roasting sulphide ores
IPC: C22B1/10
Filed: 1952-03-20
Abstract: <PICT:0730386/III/1> <PICT:0730386/III/2> Sulphide ores, particularly pyrites and zinc blende, in finely divided form are roasted in a fluidized bed by means of an upwardly directed current of compressed air or other oxidizing gas in a continuously upwardly flaring space to which the fluidized bed is confined and into the lower portion of which said gas is introduced, whereby said gas is caused to expand and exert a cooling action on the heated fluidized particles in said space, and simultaneously excess heat of reaction is removed from said fluidized bed by indirect cooling, e.g. by a heat exchange medium of high boiling point, such as a molten salt, molten metal, high boiling point oil, water, steam, or by air, which may subsequently be introduced into the sulphide ore.  In the apparatus shown in Fig. 1, ore is introduced at 5 into a wedge-shaped section 2 into which fluidizing gas is passed through nozzles 3 preferably at a linear velocity of 0.6-1.5 m./sec. at 0 DEG  C. and 760 mm. pressure. The ore is removed at the opposite end at 6, the horizontal movement being assisted by adjusting the pressure of said gas so as to be higher on the charging side. Cooling jackets 9 are provided to take up part of the excess heat, and additional cooling air may be added through pipe 10.  This form of furnace may be adapted as shown in Fig. 2 in which a plurality of small units are located side by side and provided with inter-communicating jackets 12.  Furnaces in which the bed is confined to a lower section in the form of an inverted cone are also described and illustrated.  An example of the process using pyrites is given.

Title: Improvements in or relating to air supply and control systems of air-blast circuit-breakers
IPC: H01H33/32
Filed: 1950-03-24
Abstract: 667,724. Gas-blast switches. ETABLISSEMENTS MERLIN & GERIN. March 24, 1950. [April 6, 1949] No. 7404/50. Class 38 (v). In an air-blast switch having its main blast valve adjacent to, and at the potential of, the arcing or blast chambers, the blast valve is controlled by means of a hydraulic transmission arrangement. Air is supplied to the arcing chambers indicated at 6 from a receiver 4 under the control of the main blast valve 25, which is controlled by a relay valve 21. The receiver 4 and a receiver 3 housing the valve 21 are maintained under pressure by the air supply from a reservoir (not shown) through a conduit 1 and a hollow post insulator 2. The valve 21 is opened by means of a piston 18 which is moved by a column of insulating liquid a conduit 17 and a further insulator post 8, when the column is moved by a piston 14. To open the switch, a coil 9 is energized to close an exhaust valve 33 and to open a valve 11, so as to admit compressed air from the conduit 1 to a cylinder 12. This causes the movement of a piston 13 and the piston 14 connected to it against a spring 16 and the movement imparted to the liquid column moves the piston 18 to open the relay valve 21 and to close an exhaust valve 27. Compressed air is now supplied from the receiver 3 to the operating piston 24 of the main valve 25, which is opened to allow compressed air from the receiver 4 to enter the arcing or blast chambers 6. The liquid conduit 17 is connected by way of a throttle valve 28 to a header tank 29, so as to make provision for variations in the volume of the liquid due to changes in ambient temperature, and the valve 28 may be so dimensioned or adjusted that the blast valve 25 is reclosed automatically after a short time as a spring 23 returns the valve 21 and the piston 18 to their initial positions, the liquid leaking through the valve 28, without the return of the piston 14. Otherwise, the blast valve 25 is reclosed when the coil 9 is deenergized so as to close the valve 11 and to open the valve 33 to vent the cylinder 12 to atmosphere.
