Abstract: 1,100,794. Screwing-up and unscrewing pipes. C. C. BROWN, 21 March, 1966, No. 12400/66. Heading B3N. A tool for inserting into well pipes for screwing up or unscrewing two sections C1, C2, Fig. 1, comprises a mandrel M, pipe gripping units 17, 18 mounted on the mandrel so as to engage each side of the screwed joint J, and gear means 45-47 which are operable by rotation of the mandrel, to simultaneously transmit opposite rotational forces to the units. Each gripping unit comprises a body 20 supported on the mandrel, two series of rollers 38, carried on shaft 37, and a pair of shoes 27, Fig. 5, each of which has a smooth surface 32 and toothed portions 34. Internal gear 47, Fig. 9, has projecting end portions 48, 49, Fig. 1, the former having a splined connection 50, 51 with body 20 of the gripping unit 17. Gears 46 are located in slots 53 forming a spider 52 in the lower body 20, Fig. 4. In operation, with mandrel M connected to a shaft P, Fig. 1, the tool is positioned in the well pipe. Sections 32 on the shoes 27 engage the bore of the pipe, Fig. 5, and as shaft P is rotated, this movement is transmitted through gears 45-47 and spider 52 to shoes 27 of the lower unit 18. The shoes are pivoted, and teeth 34 bite into the wall of casing section C2, Fig. 7, (not shown), and as this section is fixed in the well, further rotation of unit 18 is stopped. Gear 47 drives the body 20 of upper gripping unit 17, and the shoes 27 of this unit are pivoted, so that teeth 34 bite into the wall of the easing section C1 Fig. 6 (not shown). Continued clockwise rotation of shaft P will cause continued counterclockwise rotation of the upper casing C1, to thus unscrew the latter from casingC2. When a joint is to be tightened, the tool is turned end for end.

Abstract: 256,711. Fleet, W. F., Potter, H. V., and Damard Lacquer Co., Ltd. May 15, 1925. Samples furnished. Urea-phenol-aldehyde condensation products.- Resinous compounds are prepared by condensing urea or a substitution product with aldehydes in the presence of an amount of phenol or a homologue which varies between one-third and five times the quantity of the urea. Thiourea is mentioned as a substitution product of urea, whilst formaldehyde, acetaldehyde, and furfuraldehyde are specified as aldehydes. The best results are obtained bv condensing 33<1>/3- 100 parts by weight of phenol with 20-100 parts by weight of urea and 150-313 parts by volume of a 40 per cent solution of formaldehyde. In any case, the volume of 40 per cent solution of formaldehyde employed should be X+2.5Y, where X and Y represent the weight of phenol and urea respectively employed. An accelerator such as ammonia may be present. The reacting materials are heated together, preferably at the boiling point of the mixture, for some time, and the product then dehydrated either by boiling in an open pan or by evaporation in vacuo. After dehydration in an open pan, the viscous product is soluble in such solvents as o-toluidine, pyridine, aniline, tetrachlorethane, and ethyl lactate, and can be used either in this form or in the bard resinous form in varnish manufacture or for the preparation of moulding mixtures. After dehydration in vacuo, the resulting syrup is soluble in alcohol, acetone, butyl alcohol, and methylated spirit. Either of the dehydration products can be hardened in the usual manner. Examples are given. The Provisional Specification refers also to cresol as a starting material and to caustic soda or mineral acids as accelerators.

Abstract: 420,433. Vehicle suspensions; springs combined with screw mechanism. RILEY, P., c /o Riley Engine Co., Aldbourne Road, Coventry. May 3, 1933, Nos. 12894 and 12722. [Classes 108 (ii) and 108 (iii)] In a suspension system for road vehicles a road wheel is mounted on a fixed or pivoted part of a substantially horizontal crank 12 which is rotatable about a transverse horizontal axis and has a screw-threaded or equivalent connection about this axis with a non-rotatable member or nut 20 which is slidably mounted in a supporting casing 17 for the crank for movement against resilient means forming the spring suspension. As shown in Fig. 1, the spindle 13 of the crank is provided with helicallyarranged keys 19 engaging corresponding slots in the nut 20, forked projections on which engage flanged bushes 22 slidable on bars 23 parallel to the spindle 13. Rotation of the crank due to upward movement of the road wheel relatively to the frame, causes axial movement of the nut 20 against the compression and torsion of one or more springs 24 acting thereon and, when necessary, against the compression of additional springs 26 coaxial with the bars 23. A recoil spring 27 is compressed on opposite rotation of the crank. In a modification, the spindle has a quick-thread engagement with the nut while projections on the nut engage grooves in the casing 17. In another construction, Fig. 5, a second crank 34 is provided beneath the crank 12 and may be connected with its casing 33 similarly to the crank 12 to provide part of the spring suspension or alternatively may act as a shock-absorber. The cranks carry pins 35 supporting a member 36 forming a steering support for the stubaxle 37. In a modification, the second crank is replaced by a hinged arm serving to take the brake reaction. In a further modification (not shown), the two cranks or the crank and arm support the stub-axle through ball-and-socket means which serve to take both the steering and springing movements. As shown in Fig. 7, the casing 17 is pivotally mounted on an axis 15 for steering purposes, the stub-axle 37 being integral with the crank 12, a lower arm 40 as described above taking the brake reaction. The invention is also shown applied to a driven, steering road wheel.

Filed: 1939-05-01
Abstract: 528,685. Optical systems. SCOPHONY, Ltd., and OKOLICSANYI, F. May 1, 1939, No. 12976. [Class 97 (i)] [Also in Group XL] An optical projection system for use in a television receiver has greater magnifying power in the frame scanning direction than in the line scanning direction. By controlling the amplitude of the frame scanning pulses, a picture 7, Fig. 1, on the screen 6 of a cathode ray tube 4 whose normal dimensions would be in the ratio 10 x 8 is reduced to the ratio 10 x 4 and is reflected from a cylindrical mirror 1a having power in the frame scanning direction to a larger cylindrical mirror 2a surrounding the tube screen 6 and having power in the line scanning direction. An image having the correct proportions, 10 x 8, is thus focussed on a distant screen 5 since the magnification produced by the firist mirror 1a is very approximately twice that of the second mirror 2a. In an example given, the distances from the tube screen 6 to the mirror 1a and to the distant screen 5 are four feet and one hundred and fifty feet respectively. Instead of mirrors cylindrical lenses may be used, Figs. 4 and 5 (not shown).
