Abstract: 485,107. Turning. HERBERT, Ltd. A., and LLOYD, A. H. Nov. 14, 1936, No. 31177. [Class 83 (iii)] A steady roller, for use in combination with a lathe cutting tool, has its axis parallel to that of the work, and is fast with a supporting shank which is endwise located in both directions and journalled in an antifriction bearing of the kind including a plurality of rollers or other rotary elements. Such a steady roller 12, Fig. 1, may form part of a lathe tool box, two rollers being provided carried by arms 15 adjustable towards the work by screws 27 and clamped in position by a screw 23, Fig. 4, engaging a conical member 21 which expands the integral half-bosses of the arms within a bore 20. The cutting tool is carried on a slide 29 which may be adjusted towards or away from the work by a hand wheel 43, graduations 49 being provided for this purpose, and the tool may be relieved from the work at the end of the cutting operation by movement of a handle 38. This handle rotates a spindle 37 provided with an end piece 36, a flattened part of which is brought into line with a spring-pressed stud 34 connected by a screw thread to a boss 32 on the end of a cross-piece fixed to the tool-slide. The hand wheel 43 rotates, through a sleeve 44 and bevel gearing 45, 46, the stud 34, to effect adjustment of the tool-slide. The steady roller 12, Fig. 7, with an integral shank 13, may be journalled in two sets of needle roller bearings 14 and located endwise by a washer 16, or cylindrical roller, tapered roller or ball bearings may be used.

Patent GB-312716-A (GB)
Abstract: 312,716. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 10, 1928. Acetaldehyde is obtained from acetylene or gases containing it by the use of a catalyst comprising a solution of an acid alkali-metal sulphate containing a mercury compound with the addition of a compound of a heavy base metal of the first or eighth group of the periodic system, e.g. a compound of copper or iron. The process may he carried out at an elevated temperature and pressure, but it is preferable to commence at a low temperature, e.g. 60‹ C., and raise the temperature after one or two hours, e.g. to 125‹ C. It is also preferable to start with a smaller amount of the gas mixture, depending on the amount of catalyst employed. Pressures up to 10 atm. may be used. The aldehyde may be removed from the reaction mixture by scrubbing with suitable organic solvents, such as the higher fractions of the mixtures of alcohols, ketones, esters, etc., obtained by the catalytic hydrogenation of carbon monoxide, and subsequent fractional distillation.

Title: Method of soldering stainless steel pipes using soft solder
IPC: B23K35/36
Filed: 1974-07-16
Abstract: 1481965 Soldering SENJU METAL INDUSTRY CO Ltd and NISSHIN STEEL CO Ltd 16 July 1974 [13 Aug 1973] 31477/74 Heading B3R In joining steel pipes the pipes are arranged in telescoping relationship with a gap of 0À05- 1-00 mm between them, the gap is filled during or after its formation with solder paste comprising soft solder and flux, the pipes are heated to melt the solder in the paste and when the solder is melted further soft solder is fed into the gap. One degreased pipe 2, Fig. 1b, in an embodiment, is expanded at its end and the other degreased pipe 1, smeared with the solder paste 4, is inserted into the expanded end with the paste filling the gap therebetween. The assembly is then heated by a propane gas burner 5, Fig. 1d, to melt the solder in the paste which results in a solder coating 6 on the joint surfaces immediately thereafter, a wire 7, Fig. 1e, of soft solder is fed into the gap while continuing the heating to fill the gap. The soft solder in the paste may comprise 40-80% preferably 50% Sn and 60-20% preferably 50% Pb and this solder prerably comprises 80-20% of the paste, 20-80% of the paste being formed by a flux containing 5-50% phosphoric acid and 95- 50% ammonium dihydrogenphosphate in a vehicle. The flux may contain up to 20% of additions, e.g. copper salts, e.g. copper phosphate, copper carbonate and tin salts, e.g. tin phosphate but excluding chlorides, sulphides and nitrates. One example of the solder paste is formed of 50% of powdered solder consisting of 60% Sn 40% Pb and 50% flux consisting 68% of a mixture of 75% ammonium dihydrogenphosphate and 25% phosphoric acid and 29% diethylene glycol monoethyl ether and 3% water. The added solder wire in this case consisted of 3À5% Ag 96À5% Sn. In another example the paste is formed of powdered solder consisting of 50% Sn 50% Pb and 50% of flux consisting of 35% of a mixture of 80% ammonium dihydrogenphosphate, 10% phosphoric acid and 1% copper phosphate and 65% diethylene glycol. The added solder is a wire of 50% Sn 50% Pb. A reference to heating by resistance, infra-red ray and torch is included.

Abstract: 426,886. Type-making machines. BAILEY, J., c/o Manifoldia Ltd., Bromford Lane, West Bromwich. Nov. 13, 1933, No. 31639. [Class 100 (iii)] Galleys and galley mechanism.- Relates to means for filling type holders or magazines with short grooved type produced by a casting- machine. The type are ejected from the mould 5, Fig. 1, by a reciprocating blade 7 into a gallery 12, which consists of a groove or T- shape in cross-section formed in a plate 14. From the gallery 12 the type pass into a type holder, which preferably consists of a grooved or channelled plate, or a number of separate grooved bars or slotted tubes 15 mounted in a frame 16. The frame 16 is raised a step, as each channel is filled, by means of a pawl 27, Fig. 4, carried by a reciprocating rod 25, and adapted to engage a rack 24 on the rear face of the frame. The pawl is normally held out of engagement with the rack by an axially sliding catch-member 23. When a channel is filled, the leading type rocks a lever and withdraws the catch-member, so that the pawl engages the rack and lifts the frame 16. The lever is thereby disengaged from the type in the filled channel, and the catch-member 23 retracts the pawl. The frame 16 is prevented from dropping back by detent pawls and racks. Several detent racks of different pitch are provided, to allow for different spacing of the channels in the bars 15, and the pawls are axially adjustable by screw means, so as to engage with a suitable rack.
