Title: Process of and apparatus for the manufacture of weldless tubes
IPC: B28B21/90
Filed: 1920-07-06
Abstract: 147,025. Soc. Anon. Eternit Pietra Artificiale. Aug. 25, 1913, [Convention datel. Moulding pipes and tubes; moulding pulp.-Relates to making weldless fibro-cement tubes on a machine of the well-known paper machine type. Instead of cutting the layer deposited on the usual cylinder along several generating lines to form slabs the tube is left whole and removed from the cylinder. The ends of the tube are carefully cut away just before it has attained the desired thickness, and the cylinder is permitted to revolve for a few turns more so that the diameter of the tube increases by a few millimetres, and so is readily removable on to a core the object of which is to prevent deformation. The apparatus for carrying out the process comprises a frame a with end posts b on which are rotatably mounted sleeves c which carry the ends of rollers f, f<1>, either of which may be in the operative position, Fig. 3. After the tube is formed, the roller is rotated to a discharging position at right-angles to its former position, Fig. 2, and the other roller is brought into the. working position. The discharging-roller is now over a movable cradle p, Fig. 4, which strips the tube on to a mandrel s.

Title: Semiconductor devices cutting out a part from sheet metal by means of oxy
IPC: H01L21/314
Filed: 1974-05-01
Abstract: 1455949 Semi-conductors INTERNATIONAL BUSINESS MACHINES CORP 1 May 1974 [28 June 1973] 19027/74 Heading H1K In semi-conductor device manufacture polycrystalline Si is deposited on a substrate, e.g. of silicon nitride, in the presence of B, the B- concentration in the deposited Si exceeding the limit of solubility of B in Si at localized regions, and the Si is oxidized, preferably at a temperature in the range 800-1150‹ C. in steam. During the oxidation step the localized overdoped regions (which are believed to comprise a boron silicide) act as sources of B dopant to replace B depleted from the remainder of the Si layer due to preferential concentration of B into the growing oxide. This enables the final polycrystalline Si layer to retain the high B doping level required for such applications as Si field shields or gate electrodes for IGFETs. The desired over-doped localized regions may be obtained by depositing polycrystalline Si from a gaseous mixture of SiH 4  in N 2  and B 2 H 6  in H 2  at 750-950‹ C. Various preferred temperature and flow rate conditions are specified.

Abstract: 1448901 Making heat exchanger tubing; corrugating; rolling OLIN CORP 2 May 1974 [10 May 1973] 19391/74 Headings B3A B3E and B3M [Also in Division F4] A method of making metallic tubing having formed patterns in or on the tubing wall comprises advancing metallic strip from a supply, forming patterns on at least one surface of the strip during the course of advance, forming recurring variations in, or absence of, the patterns longitudinally of the strip, shaping the patterned strip into tubular form with its side edges in abutment and welding the abutting edges. The pattern, e.g. longitudinal grooves or diamond knurling, Figs. 4, 5 (not shown), is formed on one or both surfaces 52, 53 of the strip by profiled rolls 42-48 and one or more patterns may be applied by intermittently engaging the strip with one or both rolls of a pair. Longitudinal corrugations are formed by interengaging rolls, Fig. 6 (not shown), and these also engage the strip intermittently. The edges of the strip are scarfed, bevelled or sheared prior to forming into tubing and when corrugated tubing is formed, the abutting edges are left uncorrugated for welding, preferably by high frequency forge welding, Fig. 8 (not shown). The tubing is cut into lengths and the plain portions, when present, occur either at the ends or in the centres of the lengths. The tubes, which are preferably of steel, stainless steel, aluminium, aluminium alloy, copper, copper alloy, nickel or nickel alloy, may be used in heat exchangers, in constructional applications or for decorative purposes.

Abstract: 795,252. Preventing deposits on furnace walls. BABCOCK & WILCOX, Ltd. July 6, 1956 [July 7, 1955], No. 19647/55. Class 51 (1). In a furnace for burning ash containing fuel and discharging ash in solid form, deposits on the side walls of the furnace adjacent to air inlets are prevented by directing gaseous fluid cool relative to the slag over the furnace wall adjacent to and at least above the air inlets. In order to prevent incrustation of the walls 7 of a moving grate furnace round and above the secondary air inlets 14, part of the secondary air is directed over the side walls of the furnace. A metal or ceramic nozzle comprises locating sleeve 27, Fig. 2, held against the end of the secondary air duct 28 with its inner surface flush with the refractory lining 51 of the air inlet port and a nozzle 17 coaxial with the sleeve 27 and supported within by radial webs 26. The inlet end of the nozzle walls are tapered, and at the outlet end a concentric flange 23 provides the inner wall of an annular passage 18, flaring outwardly to direct air over the furnace walls. The main air passage contracts gradually and then widens. In a modification, Fig. 5, an arch section nozzle insert 34 is welded into the end of the secondary air duct 36 with a fantail flange 31 directing air over the part of the furnace wall on which deposits are troublesome.

Abstract: 193,345. Okabe, S. July 18, 1922. Steps.-In a mechanism for interconnecting the sliding doors of a tramcar or like vehicle with the folding steps so that manual opening of either the door or the steps effects the automatic opening of the other, a set of rollers 16, Fig. 7, mounted on a bracket 17 on the door 4, Fig. 1, is adapted to engage a spiral strip 13 rotatably mounted in bearings 14 on an axis parallel with the door so that movement of the door causes the shaft 15 to rotate, the shaft 15 being in turn connected through pivoted arms 12, 9 and a rod 11, Fig. 2, with the rotatable axles 7 on which the counterweighted steps 6 are fixed. The steps themselves can be directly operated from a handlever 27 through links 24, 28 and arms 23, 26, and by effecting a rotation' of the spiral strip 13, simultaneously operate the door. Instead of ccnnecting the arm 12 directly to the shaft 15 a clutch mechanism, as shown in Figs. 5 and 6, may be employed, so that, at the end of the opening movement of the door and steps, the arm 12 is disengaged from the shaft 15 leaving both the door and steps free for independent operation, the clutch being re-engaged only when both the door and steps are brought back to their closed positions. The clutch mechanism comprises a spring-pressed finger 30 mounted on an arm 29 integral with the arm 12 and adapted normally to engage a recess 34 on the edge of a disc 33 mounted on the shaft 15, the finger 30 being disengaged from the recess 34 at the end of the opening movement owing to its engagement with an inclined surface 36 arranged on one of the bearings 14. In a modification, the spiral strip 13 is replaced by a twisted rod which co-operates with grooved rollers mounted on the door.
