Title: Oscillator tube filament circuit for high frequency welding generator
IPC: H05B6/04
Filed: 1973-02-12
Abstract: 1413354 High frequency induction welding systems OLIN CORP 12 Feb 1973 [17 Feb 1972] 6785/73 Heading H2H [Also in Division H3] A high frequency current generator for welding metals along a seam comprises at least one oscillator tube 23 having a plate, a grid and a filament 35, the D.C. supply to the filament having a ripple of less than 20% of the magnitude of the filament current or voltage so that the generator has a ripple on its output of less than 6%. A filament transformer 40 supplies a 16 volt output from a 580 volt input across a saturable reactor 42. A full wave bridge rectifier 43 provides a D.C. voltage to a filter circuit 44 including an inductor I and capacitors C which reduce the ripple. The reduction of the generator output ripple improves the quality of the weld, for example when welding the seam of a copper tube by high frequency induction heating.

Between the flanges are a series of inclined ribs arranged to coincide with the corresponding ribs on the adjacent sections and provided with grooves 7 in which reinforcing-rods 6 are secured by grouting 8. Each flange has a continuous recess 4 and a series of countersunk holes 5 into which grouting is run to secure the sections together and make watertight joints. On the face of the plates, a further series of inclined grooves is provided, in which reinforcing-rods 9 are grouted. In a modification. separate pre-cast ribs 10 are employed, provided with grooves 12' to receive slabs 11 having diagonal grooves 14 on their front faces and diagonal ribs with grooves 16 on their inside faces. The structure is reinforced by rods 17 in the ribs. wire netting in the slabs, and rods grouted into the diagonal grooves. The slabs are joined to one another by tongue-and-groove joints, and the inside flanges 13 of the frames may have portions cut away to facilitate the insertion of the stabs. The joint between the slabs and the ribs may be provided with a series of tongues and grooves. According to the Cognate Provisional Specification 8115/18, temporary or permanent bolts may be used to fasten the plates together and to the ribs. According to both Provisional Specifications, a concrete keel is, built round the plates and frames, and their upper ends are connected by a beam of reinforced concrete. The sections may also be provided with arms or brackets to receive deck beams and transverse girders. The ends of the ship may be of solid reinforced concrete.

Title: A new or improved method of pressing glassware
IPC: C03B11/06
Filed: 1931-03-05
Abstract: 360,318. Making pressed glassware. MACBETH-EVANS GLASS CO., Charleroi, Pennsylvania, U.S.A.-(Assignees of Sloan, T. H. ; Charleroi, Pennsylvania, U.S.A.) March 5, 1931, No. 6890. Convention date, April 9, 1930. [Class 56.] A method of making pressed ware consists in placing in a mould a mass of molten glass of less volume than the articleforming cavity between the mould and its plunger. The glass when pressed does not extend to the outer edge of the cavity, and an article formed in this way has an edge which is rounded and free from seams or cracks. A mould for pressing plates is shown in section in the Figure. The plunger 3 has a number of legs 6 which make contact with the rim 7 of the mould body 1 and ensure that the plates are of uniform thickness. The edge 5 of the moulding-cavity is open to the atmosphere to allow air to escape from the mould so that it does not restrain the lateral flow of 'the glass. The plunger may be cooled to prevent it from sticking to the pressed article, or the mould and plunger may be made of different metals having different heat conductivities.

Title: Process for the production of halohydrins of styrene and styrene substituted in the side chain and/or in the nucleus
IPC: C07C31/34
Filed: 1957-03-01
Abstract: Styrene halohydrins which may be substituted in the side chain and/or the nucleus are prepared by hydrolysing the corresponding styrene dihalide in acid medium at elevated temperature.  The acid medium may be the hydrohalic acid formed during the hydrolysis or sulphuric, phosphoric, acetic or hydrochloric acids or aqueous solutions of acid salts may be used.  The reaction may be carried out at temperatures between 50 DEG  and 200 DEG  C.  The halohydrin may be isolated from the reaction mixture, or the reaction mixture may be treated with a caustic alkali to convert the halohydrin to the epoxide.  In Examples: (1) styrene dichloride is heated with water to give styrene chlorohydrin; (2) styrene dichloride, a mixture of m- and p-methylstyrene dichlorides or a methylstyrene dichloride are hydrolysed in aqueous sulphuric acid and the halohydrins converted to the epoxides, i.e. styrene oxide, m- and p-methylstyrene oxide and 2-phenyl1:2-epoxypropane, by treatment with sodium hydroxide.

Abstract: 947,301. Drying or cooling granular material. W. H. BARBOUR, and A. GASSTON. March 2, 1960 [March 2, 1959], No. 7198/59. Headings F4G and F4U. [Also in Division B1] Apparatus for drying or cooling granular material comprises a container 20, Fig. 2, having a conical lower part 21 and into which the material is charged pneumatically, an open-ended inner tube 26 having louvres 27 at its upper end, and a central cone 28 defining an annulus, e.g. up which the material is conveyed pneumatically. The material is fed into a trough 46 and flows through ports in a cylindrical port 36 of a vertically adjustable, funnel-shaped regulating device 35, 36, 37 into the lower part of the annulus 29, where it is entrained by hot or cold air flowing through passages 38 formed between the trough and a cylindrical chamber 47 supplied with air by a motor-driven blower (not shown) disposed in a base 52 forming a platform 53 for the operator. When sufficient material has been charged into the container, the regulating device is adjusted by a bolt 44 engaging a slot thus permitting the material to issue from the port 21 of the container into the stream of air flowing up the annulus 29. The materialladen stream of air on reaching the top of the annulus passes into the container from which the air flows into downcomers 54 back to the suction side of the blower in the base for recirculation, while the material falls into the container and is eventually recirculated up the annulus. The circulation of the material is repeated until it is sufficiently dry or cool whereupon it is discharged from the apparatus through an annulus controlled by sliding plate 51 and collected in bags. Fig. 11 shows a modification in which the container is oval in vertical cross-section and has a central duct 75 formed by flat plates 67 68. The air is circulated up the duct 75 and through a downcomer (not shown) at one end of the container by a blower 82 at the top of the container. The downcomer includes a heating radiator having a chimney through which a part of the circulating air may be exhausted under the control of a damper. The dried material is discharged through a shoot 91 controlled by a shutter 90.
