[Also in Division B8] A chip separator comprises a conveyor 14 for feeding a mixture of workpieces, bar ends and chips from a machine tool onto an oscillating chute 22 which deposits them in a continuous stream onto an inclined perforated grid 24 which oscillates with the chute 22. The heavier workpieces and bar ends gravitate down a slope 114 into an outlet 116 while the lighter chips are blown by a high velocity air flow passing through the grid 24 from a duct 76, into a hooding 96,100. The air flow velocity is considerably reduced in the hooding 96,100 and as the low velocity air flow is directed downwards and then upwards into a duct 88, the chips are deposited on a conveyor 92. Oil is collected in a sump 94. The air is recirculated back to a centrifugal compressor 112. Small chips that are recirculated with the air accumulate on the bottom of grid 24 and are removed by providing an air bleed passage 118 along the bottom of the grid 24 to continuously blow away the accumulated chips. The grid 24 is pivotally mounted about its lower edge and can be manually jolted to dislodge any small chips therefrom.

Title: Device for the continuous measurement of a fluid opacity

Abstract: 1,120,368. Determining opacity. COMPAGNIE GENERALE D'AUTOMATISME. Jan. 31, 1967 [Jan. 31, 1966], No.4740/67. Heading G1A. [Also in Division G3] In an arrangement for the continuous determination of the opacity of a fluid flowing in a conduit, by the transmission of radiant energy therethrough, the dimension of the conduit in the direction of the radiant beam is varied along the test section of the conduit, and the source and detector are made to be movable along the conduit under the control of a servo arrangement which maintains constant the radiant energy falling on the detector, the position of the source and detector carriage indicating on a scale the opacity. The movement of the carriage may be used to control the rate of flow from a source of a constituent being measured in order to maintain its concentration sensibly constant. The progressive change of dimension may be designed to give a desired linearity, or may be stepped, and the radiation transmission properties of the conduit reducing material may be made to compensate for a proportion of the opacity of the fluid in order to determine the proportion of a particular constituent. The conduit reducing material may be hollow and filled with a liquid having a reference opacity. The determination of the uranium content of uranyl nitrate by gamma rays is exemptified.

The outer end of the electrode 25 is covered by a retractable sleeve 29 for exposing the electrode, a scale 33 indicating the area of the surface exposed. The electrode 25 is also sheathed in metal braid 28, and the valve 3 may be housed in an internal casing 2.

Instead of the cap 29a, a collar with axially extended prongs can be provided for spacing purposes. Variation of the induced charge can be effected by altering the position of sleeve 29, or by rotating a cut-off vane between the electrode 25 and object under test. A press button 32 is employed for earthing the electrode 25. Fig. 4 shows an arrangement wherein the electrode 25 is located in an air stream that is passed through a tank 42 containing packing cardboard for photographic films. If the material is infected by radioactive emissions, the air is slightly ionized and and indication thereof is given on the meter 14.

Filed: 1917-04-03
Abstract: 106,089. Ostrejko, R. von. May 4, 1916, [Convention date]. Carbon and charcoal.-In preparing decolorizing-carbon by the action of superheated steam upon red hot carbon, the combustible gases which are formed are burned in the combustion space of the furnace which heats the retorts containing the carbon, and, when the action has been started, may constitute the only fuel. The treated carbon, after being discharged from the retorts, is heated to a white heat in the combustion space with exclusion of air. Vertical retorts b, surrounded at their lower ends by fire-proof jackets b<1>, and at the upper ends by chequer brickwork b<3>, are heated by gases from a furnace g, which also heat steam-superheating pipes f. The steam passes by pipes e into the retorts, and the combustible gases pass by perforations p and perforated slides q into passages r leading by flues s to the furnace g. Air for combustion is admitted through openings v and flues k, l. The carbon is discharged from the retorts into spaces r by withdrawing the slides q, and is conveyed through side openings g<2> to the rear portion of the fire-space in which it is heated to a white heat, air being shut off. Steam is supplied to the superheating pipes f by a tube u contained in the same flue.

[Classes 36 and 38 (i).] In order that a twin core cable of the concentric type, more particularly for use in talking film installations, may have small and constant capacity, the inner conductor consists of a thin wire supported over its entire length by an insulating carrier which is movable only axially in the hollow outer conductor. In the embodiment, a metal envelope 1 consisting of articulations 2 acts as one conductor and carries at one end a metal sleeve 3. The sleeve 3 is closed by an insulating cover 4 which has a part 5 fitting in the sleeve and formed with a groove 6. A twisted band 7 of celluloid is secured in the groove 6, and a wire 8 presses longitudinally through the band 7, portions 9 of the wire being glued to the band 7. To anchor the band 7, an eyelet 10 near the end of the band 7 is adapted to receive a wire 11 passed through a channel 12 in the cover 4, the wire being led back through a channel 13 in the cover, the wires 11, 13 being then intertwisted and soldered to the eyelet 10. The wire 8 is also soldered to the eyelet 10. Connection between the hollow conductor 1 and a metal casing 15 of electrical apparatus may be effected by a metal bayonet cap 16 in the recess 17 of which pins 18 of the sleeve 3 may be inserted. Connection of the wire 8 and the other conductor of the electric apparatus is established by a resilient contact 19 which is insulated from the cap 16 and is connected to a terminal 20. Figs. 3 and 4 show alternative forms of carrier. In Fig. 3 a band 21 has punched out rectangular portions 22 bent at rightangles to the plane of the band 21. In Fig. 4 the carrier consists of a triangular body 23 of rubber.
