Title: Determining the length of a rolled workpiece
IPC: B21B38/00
Filed: 1976-07-02
Abstract: 1516403 Monitoring steel plate BRITISH STEEL CORP 2 July 1976 [3 April 1975] 13712/75 Heading G1N The thickness of steel plate produced in a rolling mill, as determined by the screwdown position indicator 11, and its length, as determined by the number of revolutions of one of the rolls, measured by a pulse generator 12, in association with its known diameter, are compared with a target thickness at 17 and a target length at 18. Strain gauge load cells 10 attached to the mill housing establish when the plate enters and leaves the rolls, and modify at 13 the screwdown position indication in accordance with the mill elasticity, to establish the actual plate thickness. If h 0 , h 1  are the plate thicknesses for successive passes and d the circumference of the roll, the actual length l 1  of the strip is given by where k is a known constant for the particular mill. These values of l 1  and h 1  are utilized in the formula l n  À h n  = l 1  À h 1  to determine the length l n  after n passes for a target thickness H or the thickness h n  for a target length L. If the original targets H, L are not attainable more appropriate final values are established for use in the rolling control system 21.

Abstract: 667,354. Indicating direction of magnetic adds. BENDIX AVIATION CORPORATION. June 5, 1950. [July 1, 1949] No. 14017/50. Class 40 (i). A flux-gate compass 1 is energized from a source 17, 19 of relatively high frequency e.g.. 5 kc/s, and is coupled to a receiver 3 whose rotor, when not in the plane of the resultant field, generates a signal of double the frequency of 17, 19 ; this signal is applied to a phase-sensing circuit 27 so that an output is obtained dependent on the phase relationship between the signal and an oscillation of the double frequency from 51 ; this output controls a motor 75 to return the rotor 15 to the plane of the resultant field, the motor being fed with relatively low frequency e.g. 400 c/s. The phase-sensing circuit 27 is preferably as disclosed in Specification 684,955, [Group XL (c)]. The output is applied to a magnetic amplifier 63 so that according to the phasesense of oscillations from 15, current flows through one or other of saturating windings 65 to permit one or other of secondary windings 69, 71 to supply winding 73 of motor 75 and operate motor 75 in the appropriate direction. A filter 23 removes unwanted oscillations from the output of rotor 15, and a similar filter may be employed with the output of the frequency doubler 51.

Title: Process for improving cellulose textile material by crosslinking
IPC: D06M13/12
Filed: 1962-04-11
Abstract: Cellulosic textile materials, e.g. cotton fibres, yarns and fabrics, are creaseproofed by the application of agents capable of cross-linking cellulose in steps in such a manner that in the first step the cellulose is crosslinked until insoluble in copper oxide/ ammonia solution but still at least slightly swellable therein, the textile material being stretched at least partly after applying the crosslinking agent but prior to crosslinking in at least one direction to more than 10% of the extension at break of the textile material, the rearrangement of the fibres and yarns created by stretching being fixed by crosslinking, and subsequently in a second step a further amount of the same or a different crosslinking agent is applied to the textile material and rendered fast to washing without previous stretching. Specified crosslinking agents which may be applied by padding, spraying or roller transfer from aqueous or non-aqueous solutions, dispersions or emulsions or from gas phase are precondensates of heat-curable resins produced by the reaction of aldehydes, e.g. formaldehyde, glyoxal, acetaldehyde or acrolein with acid amides, urea derivatives particularly cyclic ureas, ureins, triazones or other heterocyclic compounds carrying at least one -CO-NH group, aldehydes, e.g. formaldehyde, glyoxal, acrolein or acetaldehyde, applied as such or in the form of acetals, enol ethers or polymers, compounds containing epoxy, isocyanate, vinylsulpho or other reactive vinyl or acryl groups, or halogen atoms, halohydrins, di- or polycarboxylic acids as such or in the form of acid halides or esters, di- or poly-functional "onium" compounds, e.g. sulphonium and phosphonium compounds, and the reaction products of two carbonyl compounds, e.g. two aldehydes or an aldehyde and a ketone.  The treating compositions may also contain swelling agents, compounds influencing friction between the fibres, dyestuffs or dyestuff forming compounds, pigments, hand building additives, softeners, e.g. polyethylene or silicones, thermoplastic polymers and optical brighteners. Crosslinking may be effected in the presence of acid, alkaline, potentially acid or alkaline or free radical catalysts or radiation capable of inducing crosslinkage.  Prior to the second step the textile material may be subjected to known chemical and/or mechanical treatments or compressively shrunk and prior to, during or after the treatment the material may be subjected to modification by causing substitution of single hydroxy groups, by deposition of polymeric compounds within the material, by polymerizing monomers in situ or by graft polymerization.  The first step may be carried out on the yarn and second step carried out after the yarn has been converted into a fabric.

The hexagonal apertures 32 and pins 20 shown may alternatively be square, triangular, oval, or circular with complementary radial projections and recesses to facilitate mounting of the mandrels with their respective planes of symmetry in alignment, except when circular mandrels are employed. The mandrels 19 may be tapered to facilitate removal from the casting. The mould may alternatively be fabricated from non- moisture-absorbing materials when employed, e.g. for an hydraulic setting material. The mould base-plate 15 is cast around the anchor elements (30) (Fig. 5, not shown), provided with circumferential securing grooves (31), on a wooden master pattern (40) provided with upstanding pins (41) on which are located the anchor elements (30); the pins (41) are preferably coated with silicone stop-cock grease. The mandrels 19 may alternatively be provided with a resilient pin when the anchor elements 30 are rigid. The mandrels may alternatively be provided with an aperture and the anchor element with the pin. In each case one of the pin or anchor elements is rigid and the other is resilient.
