Title: Magnetoelastic shape measuring equipment
IPC: G01L5/04
Filed: 1976-01-23
Abstract: 1529101 Measuring shape of metal strip electrically ASEA AB 23 Jan 1976 [24 Jan 1975] 02642/76 Heading G1N The shape of a metal strip is measured by means of a plurality of stress measuring transducers which are magnetically screened from one another. Each transducer 1 is of the type described in Specification 754474 comprising a pair of U-shaped cores 7, 8 disposed at right angles to one another, the windings on one core being A.C. energized and inducing a magnetic field in a strip to be monitored, the windings on the other core sensing assymetry in the field caused by tensile stress in the strip. The transducers are mounted on plate 11 extending along a box shape beam 2 and each is surrounded by a magnetic screen 12, the top of the beam being covered by a plate 20 of non-magnetic high resistivity material and over which the strip passes. The transducers are spaced at equal distances from each other which distance may be changed by means of a lazy tongs device, Fig. 6 (not shown) having links 14 to which the transducers are connected, the middle transducer being fixed in position. Each transducer is orientated so that the yokes of the cores make an angle of 45 degrees with the axis of the beam, Fig. 4 with every second transducer rotated 90 degrees with respect to the adjacent transducers to reduce magnetic coupling therebetween. The output from each transducer is filtered to obtain the fundamental, amplified and synchronously rectified. The superimposed A.C. is filtered out and the average of all the resulting direct voltages from each transducer obtained which is then subtracted from the individual outputs to obtain an indication of the stress distribution in the strip which is related to the shape (flatness) of the strip. The device may be mounted between two deflection rolls. A method of calibration is referred to.

Patent GB-785976-A (GB)
Title: Improvements in or relating to thermosetting molding compositions
IPC: C08G12/02
Filed: 1954-02-02
Abstract: In making thermosetting moulding compositions, urea, melamine, biuret or thiourea is mixed with substantially dry paraformaldehyde and an absorbent cellulose filler, and heated in a closed vessel at a temperature sufficient to bring about condensation with liberation of water, which, when condensation is complete, is allowed to escape from the vessel as vapour, thereby cooling the mixture and stopping reaction.  Fillers mentioned are wood-flour, sulphite pulp or a -cellulose.  Curing catalysts, e.g. epichlorohydrin and, if desired lubricants, dyes, pigments or plasticizers are added, preferably to the cooled mixture.  If desired the charge may be transferred to a second mixer, preferably having a cooling jacket, at the beginning of the cooling.  The moulding composition is densified into lumps and freed from remaining traces of water by mixing or kneading in heated apparatus, and then granulated or ground.  In an example urea, paraformaldehyde, a -cellulose, ammonia, hexamine, zinc stearate and pigments or dyes are mixed in a jacketed ribbon-typemixer which is closed and heated to 200-230 DEG  F.  After reaction, the mixer is opened.  Vapours escape and the temperature falls to 180 DEG  F. Additional hexamine and epichlorohydrin or other latent catalyst is added and the mixture transferred to a cooled mixer and thence to a heated densifier provided with a suction fan to remove remaining water.  The material is discharged on to a conveyer to a crusher to cut it to small pieces and then to a second cutter for final granulation.  Triethanolamine may replace ammonia as buffering alkali.  When the proportion of filler or pigments used is high, a small quantity of water may be added to the initial mix to facilitate uniform admixture.  The granulated product may be ground to a fine powder, and colouring materials may be added at this final grinding stage if desired.

Filed: 1929-01-30
Abstract: 327,226. Rowland. T. C. E., and Baker, A. C. Jan. 30, 1929. Obstruction-removers and safety-appliances.- In a vehicle life-guard of the kind in which a main guard is adapted to be lowered when either it or a. pilot guard meets an obstruction, both guards are normally arranged to be substantially vertical and the pilot guard 20 on encountering an obstruction causes the main guard 12 to be lowered while the pilot guard is raised. In the construction shown the main guard 12 is supported at each side by two L-shaped arms 10 pivotally connected to levers 8, 9 fixed to transverse rotary shafts 6, 7 mounted in fixed frames 1. The pilot guard 20 is supported by arms 19 which pass through slots in the main guard 12 and have depending arms 21 pivoted at 22 to levers 23 on the shaft 7. Between the pivots 22 and fixed pivots 26 on the frames 1 are arranged sleeves 25, which surround compression springs 26<a> and form toggles with the levers 23. The rear ends of the arms 19 are associated with tension springs 28 and are provided with cam members 31 adapted first to guide the arms 19 rearwardly with a sliding movement in slots 32 in the frames 1 and then to co-operate with camshaped depending bars 35 to allow the pilot guard and arms 19 to swing about the pivots 22. Levers 37, 38 and a link 39 are interposed between the shafts 6, 7 so that these rotate in unison. Normally the parts are positioned as shown in Fig. 1, and, when an obstruction is met, the pilot guard 20 and arms 19 are forced backwards, the first part of the movement being horizontal. Ultimately the pivots 22 pass to the rear of their dead centre positions, and the cams 31 pass on to the bars 35, both sets of springs 26a, 28 then functioning to raise the pilot guard to the position shown in Fig. 2. During this movement the shafts 6, 7 are simultaneously rotated, and the levers 8, 9 carry the main guard to a rearward dropped position. A pivoted lever 15, link 14, and lever 13 are provided to permit the driver to re-set the guard or to lower it non- automatically.

Title: Improvements in apparatus for washing out oil tanks, vats, and the like containers
IPC: B05B3/06
Filed: 1947-02-04
Abstract: 623,780. Spray - producers. MERRYWEATHER & SONS, Ltd., STUBINGTON, R. E., and MILLER, L. C. Feb. 4, 1947, No. 3297. [Class 69 (iii)] A reaction jet type water distributer for washing out oil tanks &c. comprises a rotating nozzle member carrying tangentially disposed nozzles, Fig. 1, which also rotates in a horizontal plane, having means for ensuring its continued rotation under varying conditions of water pressure and against temporary obstructions in the working parts. In the embodiment a stationary feed pipe D carries a fixed horizontal gear wheel E, under which a separate member F is attached, such that it rotates in a horizontal plane. Member F contains a rotary pump G, and a circular sleeve H on which a sleeve portion J of the rotating nozzle member is mounted. Sleeve J carries a gear wheel K engaging with wheel E. A hollow shaft L passes from a gear of the pump G, through F and carries a coupling member M loosely connected to a coupling member N secured to the nozzle rotating member. A port O connects the delivery side of the pump to the shaft L, whose other end connects with a leak hole P. The water outlet from the leak hole is dependent upon the relative positions of members M and N, and normally is slight. When pressure water is supplied through pipe D to the nozzles and pump G, the nozzles rotate as described, and the rotary gear pump G is operated. The restricted outlet causes a resistance to pump rotation, and through shaft L a resistance to rotation of the nozzle member J. Undue resistance or obstruction producing a lag in nozzle rotation causes coupling member M to move in advance of member N, the pump water outlet is thereby greatly increased and pump G drives the nozzle member.

Title: Recovering trimethylolethane
IPC: C07C31/18
Filed: 1955-06-08
Abstract: Trimethylolethane is separated from an aqueous solution of trimethylolethane and sodium formate by a process comprising adding to the solution an organic solvent for trimethylolethane, the solvent being a non-solvent for sodium formate, to form a multiphase mixture comprising a liquid aqueous phase containing water and most of the dissolved sodium formate and a liquid organic solvent phase containing the solvent and most of the trimethylolethane, and separating the organic solvent phase from the aqueous phase. Suitable organic solvents comprise alcohols, such as n-propanol and isopropanol.  Trimethylolethane may be recovered from the organic solvent phase by, for example, heating the phase in the presence of added water to remove the solvent and to produce an aqueous solution of trimethylolethane from which it is obtained by crystallization. Advantageously the amount of water present during the extraction is insufficient to dissolve all of the sodium formate in the presence of the organic solvent. The extraction may be carried out continuously or otherwise.  It is sometimes desirable to add to the starting mixture a mixture of water and the organic solvent rather than the organic solvent alone.  For example, an azeotropic mixture of isopropanol or n-propanol and water may be added.  This mixture may be obtained, for example, by steam-stripping the propanol-containing phase.
