Filed: 1965-12-14
Abstract: 1,093,169. Lathe tools. VALERON CORPORATION. Dec. 14, 1965, No. 52967/65. Heading B3B. A toolholder assembly is provided with a pocket recess 12 in the toolholder body 10 in which an indexable cutting bit 14 is mounted on a shim seat 13 so that its upper face is located slightly above ledges 16 formed at the base of a chipbreaker pocket 15 which is of slightly larger dimensions than the cutting bit recess 14; the arrangement is such that in the assembled tool the chipbreaker 17 is clamped upon the cutting bit 14 but if the latter is removed it rests upon the ledges 16. A spring washer 29 located between the clamp element 23 and the clamping screw 25 maintains pressure on the chipbreaker when the clamping screw is slackened. A V- projection 22 on the clamping element 23 counteracts any tendency to rotation of the clamping element. A locating pin 27 passes loosely through the clamp element and projects into the chipbreaker 17. In a modification (Fig. 6, not shown) the cutting bit is square instead of triangular. In a further modification (Figs. 10-14, not shown) a V-projection extends transversely across the clamping element to prevent rotation during tightening of the clamp screw.

Title: Monitoring of particle size distribution
IPC: G01N29/032
Filed: 1972-11-20
Abstract: 1410954 Monitoring particle size distributions ultrasonically AUTOMETRICS CO 20 Nov 1972 [23 Nov 1971] 53530/72 Heading H4D In what is essentially a development of the invention of Specification 1,329,564, the size distribution of particles suspended in a fluid is monitored by measuring the attenuation of an ultrasonic beam by the suspension to obtain a first signal including a function of the size distribution, developing a second signal including a function of the percent by volume of particles in suspension, and forming the ratio of the two signals to obtain a signal representing the size distribution. The Fig. 6 system includes transmitting transducers 5, 5<1> energized by gating the outputs of oscillators 3, 3<1> having different respective output frequencies. The resulting ultrasonic beams traverse agitated ore slurry in container 16 and are received by transducers 6, 6<1> whose outputs are converted to D.C. signals at 7, 7<1> then logarithmically compressed at 8, 8<1> and amplified at 9, 9<1>. The frequencies are selected such that one resulting input to a dividing circuit 10 represents beam attenuation as a function of the particle size distribution and of the solids-to-fluid ratio of the slurry, whereas the other input to divider 10 represents attenuation as a function of the solids-to-fluid ratio but is independent of the size distribution. The quotient formed by divider 10 is thus represesentative of the size distribution alone. Processor 11 provides signals representing the size distribution to indicating and/or controlling devices 12, 13, and provides signals representing percent solids of the slurry tu indicating and/or controlling devices 12<1>, 13<1>. A single pair of transducers, or a single transmit/receive transducer plus a reflector, may be used (instead of the two transducer pairs shown) to measure ultrasonic attenuation at the two frequencies alternately and thereby avoid signal cross-talk (Figs. 17 and 19, not shown). Measurement of attenuation at more than two frequencies, using further transducer pairs, is envisaged to enhance the measurement accuracy by making the size distribution and percent solids signals more independent. Criteria for frequency selection, the regulation of an ore grinding mill, allowances for the presence of entrained air in the slurry, and correlation of the attenuation measurements with mesh screen measurements of size distribution are discussed.

Abstract: 1449396 Measuring electrolysis parameters in a melt SWISS ALUMINIUM Ltd 18 Dec 1974 [20 Dec 1973] 54774/74 Heading C7B Electrolysis parameters in a metal-producing melt are continuously measured using an anodic measuring surface of inconsumable ceramic oxide wettable by the melt and which is protected at least at the electrolyte/air interface from the electrolyte, and through which is passed at all surfaces exposed to the melt a measuring current of at least 0.01 A/cm<SP>2</SP> either to an inert cathode located in the melt or to the metallic electrolysis product. The ceramic may be an oxide of Sn, Fe, Cr, Co, Ni, or Zn with optionally 0À01-20 wt. per cent of one or more oxides of Fe, Sb, Cu, Mn, Nb, Zn, Cr, Co, W, Cd, Zr, Ta, In, Ni, Ba, Bi or Ca. It may be a coating on a substrate e.g. Ni, Cu, steel, Co, Mo a carbide, nitride, or boride with optionally an intermediate Ag layer. The protection may be with a bad conductor e.g. BN, Si 3 N 4 , Al 2 O 3  or MgO and may be solidified melt obtained by internally cooling the anodic surface. Alternatively an oxidizing gas may protect the ceramic, being provided internally for a porous ceramic or externally. Gas produced by electrolysis at the anodic surface may be deflected to effect protection. A protective gas film may also cover those parts of the surface where the minimum c.d. is not attained. Gases listed are O 2 , air, Cl 2 , F 2 , CO 2  and nitrogen oxide. The cathode used for measuring e.g. molten Al when determining the level thereof, or a fixed cathode of carbon, graphite or a boride, carbide, silicide or nitride of C, Si or a Group VI-VI transition metal. The melt may be of cryolite with Al 2 O 3  or of Mg O or Be O. For measuring electrolyte resistance or (e.g.) Al level the anodic ceramic requires low temperature coefficient of specific resistivity at 950-1000C and a low resistance compared with the melt (e.g. SnO 2  with 2% Sb 2 O 3  or 2% Cu + 1% Sb 2 O 3  or 2% Nb 2 O 5 ) while the converse is required for measuring temperature (e.g. SnO 2  with 2% Fe 2 O 3  or 10% CuO). The measuring anode and cathode may be held in a non-conducting frame of generally inverted U-shape, in which apertures face each other across the sides of the U to allow current flow when immersed in the melt.

The sides 4, 6 of block 12 form latch guards for the cylinder and dial needles. Yarns from four feeder tubes 40 belonging to a stringer unit pass to grooves 16, 18 in block 12 from between which projects hook 24. In operation, at the feed associated with the latch guard, a thin yarn LY is fed in front of hook 24 to groove 18 and to the dial needles only while Terry yarn TY is fed to the dial needles and selected cylinder needles. At a subsequent feed, ground yarn is fed to all non-terry cylinder needles and all dial needles or to dial needles only. After this, the dial needles remain inactivated and the cylinder needles selected at the latch guard are selected again and the loops pressed off to form terry loops of yarn TY. Rib fabric may be knitted immediately following the terry loop fabric by selecting the cylinder and dial needles (which are suitably arranged with high and low butts) to produce a 1 x 1 or 2x2 rib and removing yarn LY from operation and trapping and severing it, following the rib border, a welt and a draw thread, further terry loop patterned fabric may be produced. On reactivating the guide carrying yarn LY, the yarn is guided by hook 24 into groove 18.

A second earth terminal I protects the other electrodes of the C.R.T. 3, 5, 6 through discharges 3<SP>1</SP>, 5<SP>1</SP>, 6<SP>1</SP>, both the earth terminals, I, II being connected to chassis earth. The dischargers 2<SP>1</SP>, 3<SP>1</SP>, 5<SP>1</SP>, 6<SP>1</SP> are spark gaps. Flashover initially causes 3<SP>1</SP>, 5<SP>1</SP>, 6<SP>1</SP>, to break down, and the earth I to rise in potential as a result, this however not being transmitted to T22. A rise in cathode 2 voltage first makes D1 conduct to protect T22 until the spark gap 2<SP>1</SP> conducts to divert fault current. The inductance of the signal leads 13, 23 protect T21.
