Title: Computer controlled rolling mill
IPC: H02P5/68
Filed: 1972-11-17
Abstract: 1402129 Rolling mills GENERAL ELECTRIC CO 17 Nov 1972 [19 Nov 1971] 53232/72 Heading B3M [Also in Division G3] An automatic rolling mill is controlled by a digital computer wherein is stored functions relating the variations of a rolling parameter for a chosen per unit draft. A roughing mill 10 includes a plurality of tandem stands RS1-RS3 for reducing the thickness of bars B 1 -B 3  passing sequentially. Each stand has confronting rolls R1, R1<SP>1</SP> driven by a synchronous motor DM1-DM3, and the load on the rolls is measured by a load cell LC1-LC3. The reduction of the bar at each stand is determined by work roll separation established by screwdown SD1-SD3 actuated by drive SDPD1-SDPD3. The separation of each pair of rolls is measured by a position indicator ESP11-ESP13. The width of a bar is determined by vertical rollers VR1-VR3 driven by motors VDM1- VDM3. The reduction in bar widths is controlled by mechanisms EAM1-EAM3 actuated by drives ESPD1-ESPD3. The widths are measured by indicators VSDP11-VSDP13. The output signals from the indicators and load cells are fed to a process control computer C20 which establishes the draft taken by each set of confronting rollers. The power taken by the motors DM1-DM3 is measured directly, or derived from current sensors A1-A3 and voltage sensors V1-V3 and fed to the computer. The computer receives order information from a card reader 22 and process information is displayed by a typewriter or line printer 24. Process information includes temperature from a pyrometer P and thickness from an optical detector D co-operating with a scanning light source L. During operation of the mill the computer carries out a drafting schedule arranged to provide maximum draft at the last stand RS3 and minimum draft at the first stand RS1. The rolling force for each stand is determined from a mathematical model which is stored within the computer as (a) ratio of actual force to force for a chosen draft plotted against elongation and (b) the force for the chosen draft plotted against the reciprocal of output thickness. These curves are normalized i.e., made to intersect at the chosen draft. The determined normalized force and force ratio are multiplied together and modified by empirically determined factors dependent on known width and resistance to deformation of the bar to provide a predicted roll force which is fed to control a mill stand.

Title: Photoelectric Weft Detecting Device
Inventor: MIZUKOSHI HIROSHI
IPC: D03D51/34
Filed: 1966-11-29
Abstract: 1,166,084. Weft detector for looms. H. MIZUKOSHI. 29 Nov., 1966, No. 53303/66. Heading D1E. A photoelectric device for indicating depletion of weft in a shuttle includes a lamp on one side of the shuttle race and a photocell on the other side, the shuttle and bobbin having apertures through which the light can shine when the weft uncovers the aperture in the bobbin. A differentiating circuit generates pulses of one polarity when the illumination of the cell changes from light to dark and of the opposite polarity when the change is from dark to light; a rectifying circuit eliminates the former pulses and retains the latter pulses, which occur when light passes through the aperture in the bobbin on depletion of weft and also every time the trailing end of the shuttle uncovers the cell. The first of such a pair of pulses opens a gate for a predetermined time and the second passes through the gate to indicate depletion of weft. When the aperture in the bobbin is still covered with weft, the pulse produced by the trailing edge of the shuttle finds the gate closed and therefore cannot generate an indicating signal.

Abstract: 1415108 Purifying hydrocarbons INSTITUT FRANCAIS DU PETROLE 16 Nov 1973 [16 Nov 1972 29 Nov 1972 26 Feb 1973] 53431/73 Heading C5E Aromatic hydrocarbons and/or organic sulphur compounds are removed from hydrocarbon mixtures by adsorption on a macroporous ion-exchange resin containing less than 2 wt. per cent water and containing ammonium, hydrazinium or substituted ammonium cations. The feedstocks treated are gasoline, white spirit, a toluene-containing C 8  paraffinic and naphthenic fraction, a mixture of heptane and benzene and a 250-350‹ C. boiling range fraction. In examples the resins used have sulphonic groups and have been exchanged with ammonium, monoethanolamine, diethanolamine or dimethylamine ions and are compared with resins exchanged with K<SP>+</SP>, Na<SP>+</SP>, Ba<SP>++</SP>, Fe<SP>++</SP> and Cr<SP>+++</SP> ions. After use, the resin can be regenerated by contacting with a gaseous or liquid elution agent, such as ammonia or a saturated hydrocarbon of different boiling range from the adsorbed components. The feed 1 can be contacted with the resin in a column C 1  to form a stream 3 containing unadsorbed components which is distilled at C 3  to separate elution agent 6 and the unadsorbed components 7. The resin in C 1  is regenerated by passing an elution agent through this column to desorb impurities as a stream 12 which is separated at C 4  into elution agent 17 and the impurities 14. Two or more columns C 1  and C 2  of resin alternate in adsorption and regeneration stages with purge material being recycled from one column to another via the lines 2 and 8 respectively.

Abstract: 1,133,217. Plate heat exchangers. SOC. ANON. ANDRE CITROEN. 20 Dec., 1965 [31 Dec., 1964], No. 53859/65. Heading F4S. A heat exchanger consists of a corrugated sheet constituting either a secondary surface element in a fluid passage (Figs. 1 to 3), or a heat transfer wall separating two fluids, said sheet being mounted on a plate so that the corrugations make continuous line contact along their lengths with the plate, the sheet being additionally corrugated in a direction transverse to the main corrugations such that the lines of contact between the sheet and the plate are sinuous. The heat exchanging fluids may be liquids or gases and the relative fluid flow may be cross-flow or contra-flow. The drawings show a contra-flow arrangement in which each corrugated sheet 6 is arranged between two plates 7, 7a respectively. The plates 7 comprise an outer casing of the heat exchanger completed by end plates 11. The plates 7a are shorter than the plates 7 to provide header spaces as shown, and are spaced apart by transverse walls 9 arranged as in Fig. 6. The walls 9 define inlet and outlet passages 10, 10a respectively for one of the fluids. The end walls 11 are apertured to provide inlet and outlet openings 8 for the fluid X flowing on one side of each corrugated sheet 6. The other fluid Y enters the passages 10 from one side of the heat exchanger and passes from these into the internal header space (the right-hand space between plates 7a and end wall 11 in Figs. 4 and 6), from whence the fluid divides into streams which flow over the corrugated sheet surfaces to the other header (left hand side of Figs. 4 and 6) whence the fluid streams recombine and flow into the passages 10a to be discharged from the other side face of the heat exchanger as shown. Other forms described (Figs. 8-10) comprise a single corrugated sheet (12) sandwiched between two plates (13, 14) or a single corrugated sheet mounted on one plate. In this latter form the corrugated sheet and plate provide only one set of heating fluid passages, the other fluid being a gas which is heated by contact with the corrugated sheet.
