Title: Improvements in or relating to metallic packing for rotary engines, pumps and the like
IPC: F16J15/54
Filed: 1923-06-21
Abstract: 219,463. Daw, A. W., and Daw, Z. W. June 21, 1923. Stuffing-boxes, substitutes for.-Packing for a rotating shaft or casing consists of a loose ring 3, Fig. 1, pressed by the fluid pressure, aided, if necessary, by springs, against the ends of a sleeve 2 carried by the packing box and a sleeve 1 on the shaft. The sleeve 2 has an outer flange secured against a shoulder in the box by a gland 7 and an inner flange forming part of the seating of the ring 3. The sleeve 1 is movable on the shaft and contains packing compressed by a gland 6a. The end abutting the sleeve 2 and a collar 1<a> on the sleeve 1 are formed with radial grooves to permit escape of leakage. The ring 3 has radial grooves at its inner end and is preferably hollow and flexible with a deep groove opposite the clearance between the sleeves 1, 2. In modificaltions, the sleeve is formed in concentric parts with a diaphragm between the parts secured by screw caps or sprung into grooves in the parts. Alternatively, one of the parts may be a split ring or packing rings 11<b>, Fig. 6, may be provided between the concentric parts 11, 11<a> of the ring. The shoulder in the packing box may be dispensed with, the sleeve being secured by studs or by projections 23 engaging holes in the box. In the later case part of the box is removable to permit insertion of the sleeve. The inner sleeve may be located by its packing 26 engaging a groove in the shaft. Alternatively, the inner sleeve may be replaced by a shoulder on the shaft.

Abstract: 798,949. Welding by fusion. IMPERIAL CHEMICAL INDUSTRIES, Ltd., TERRY, C. A., and TINSLEY, A. B. Sept. 6, 1956 [June 6, 1955], No. 16130/55. Class 83 (4). A backing ring 1 for use in submerged arc welding a circumferential joint between tubes 13a, 13b is formed with a groove 3 in which is positioned an inflatable tube 4 adapted to press flux against the back of the joint. The ring 1 is made in three sections joined by hinges 7 and is provided with a threaded device 10 serving to expand the ring 1 against the tubes or to allow collapsing of the ring. Flux from a hopper 18 is blown by compressed air from a pipe 21 through conduit 22 connectible to an inlet 16 leading to the groove 3. When the groove has sufficient flux a valve shuts the inlet 16. The tube 4 is inflated with a pressure of up to 4 1b./sq. inch when welding steel tubes of thickness 0.064-0.15 inch. The pressure may be controlled manually or automatically as the work is rotated under a submerged arc welding head 32.

Title: Flexural quartz crystal vibrator
Inventor: OGUCHI KIKUO
IPC: H03H9/215
Filed: 1974-04-11
Abstract: 1460637 Quartz flexural resonators SUWA SEIKOSHA KK 11 April 1974 [7 May 1973] 16201/74 Heading H1E A flexural quartz resonator has electrodes on one side only. In the embodiment of Fig. 3 a "tuning fork" resonator made from a thin cut of quartz is provided with electrodes 12, 13 on the upper face only. The tines 11 of the fork vibrate in a plane parallel to the electrodes. The cut has zero temperature-coefficient and is derived from an X-cut plate by a first rotation of α (0 to 10 degrees) about the X axis, and a second rotation of γ (Œ 70 to Œ90 degrees) about the Y<SP>1</SP> axis. An alternative electrode pattern is shown in Fig. 8. The plated area 35 is non-active and serves to assist in attaching the resonator to a mounting structure. Areas 34 are also non-active and provide adjustable loading which is selectively evaporated by a laser in order to tune the resonator. In a modification of this electrode pattern (Fig. 7, not shown), electrodes 22, 24 and 25, 27 merge with the plated areas 34, and plated connections are provided near the stem of the fork to connect electrode 23 to electrode 27 and electrode 24 to electrode 26. Both the fork and the electrode pattern are produced by a photo-etching technique using a gold-on-chromium layer for the mask. After etching of the quarts to form the fork, the mask is selectively etched to form the electrodes.

Title: Treating metal surfaces
IPC: C23C22/03
Filed: 1978-04-25
Abstract: The workpiece surfaces are first treated with a mineral oil-based phosphating agent which contains an acidic product formed by polyphosphoric acid with an aliphatic alcohol as well as water and solubiliser, in a homogeneous phase. In this way, a stable iron phosphate layer is formed. This is followed by an after treatment with a mineral-oil based agent which has a basic reaction and contains a selected special combination of defined constituents. The procedure is characterised in that advantageous corrosion protection results are obtained and the procedure can easily be monitored in operating practice.

Title: Method and apparatus for weighing loads
IPC: G01G7/02
Filed: 1935-06-05
Abstract: 440,244. Weighing-apparatus. BAERMANN, M., 30, Deutscher Ring, and DYNAMIT AKT.-GES. VORM. A. NOBEL & CO., Troisdorf Bez, both in Cologne, Germany. June 5, 1935, No. 16353. Convention date, June 9, 1934. [Class 143] In a weighing-apparatus the load is balanced by the magnetic force exerted on an armature guided by adjustable rollers and free to move without any mechanical support, in the field of a permanent magnet, the position attained under load being an indication of the weight. As shown, an armature 3 situated between the poles of a permanent horse-shoe magnet 2 is guided by rollers 5 and carries a similarly guided rod 6 of non-magnetic material supporting the scale pan 8. A load on the pan depresses the armature, and a rack 9 actuates the indicating pointer 11 to indicate the weight. In order to obtain evenly divided graduations on the scale 12 the pole shoes or the armature may be rounded off or the armature may be hollowed out. An adjustable magnetic byepass may be provided on the magnet to permit of adjustment for change in strength of the magnetic field. In a modification, a battery of magnets with similar poles assembled together is used and the vertical pan-supporting rod forms the armature. The pole shoes of the battery of magnets are adjustable towards and away from the armature by hand wheels. The displacements of the armature are transmitted by flexible bands and rectifying cams to an indicating pointer moving over an evenly divided scale. In a further modification the armature is of bell shape and encloses the pole shoes. The device instead of weighing the load directly may be arranged to weigh the load applied to a decimal or centesimal weighbridge of the balanced type.

Abstract: 111,164. Barker, R. W., (American Bank Note Co.). Nov. 17, 1916. Electrotype.-Engraved steel or other intaglis printing-plates are reproduced electrolytically in steel or iron, by making a relief impression from the original in a ductile electro-conductive metal such as lead and using the matrix as the cathode of an electrolytic bath of iron sulphate solution containing about 1 per cent. of vanadium chloride or about the same percentage of nickel sulphate or the double sulphate of ammonium and nickel. Sodium bicarbonate or other neutralizing agent also is preferably added. The anode is preferably of pure iron and the bath is kept at the temperature of about 160‹ F. To obtain a more homogeneous plate, the matrix is given a slow rotary or other movement in the bath so as to bring all portions of it into contact with electrolyte differing in density, hydrogen bubbles are periodically removed from the cathode by mechanical means or by reversing the direction of the current, and oxides or other precipitates in the bath are removed by keeping the electrolyte in constant circulation through a filter, fresh water or solution being added as required. The lead matrix may be coated with copper before insertion in the bath, this coating adhering to the matrix when the plate is removed.
