Title: Improvements in hydraulic accumulators
IPC: F15B1/08
Filed: 1942-05-26
Abstract: 551,847. Hydraulic accumulators. CHRISTENSEN, A. H. H. May 26, 1942, No. 7125. [Class 69 (ii)] A hydraulic accumulator is connected in the supply line from an electrically driven pump to a press or other apparatus, and is constructed, so as to maintain a constant pressure in the supply line, of a vessel 6 comprising an upper part filled with pressure liquid and connected by an outlet 1<SP>1</SP> to the supply line. A diaphragm 11 separates the liquid from the lower part 23 of the accumulator which is connected by passages 21, 22 to a compressed air-chamber 24, which is at the pressure desired for the hydraulic liquid. A spring-pressed stem 13 is arranged below the diaphragm 11 and is fitted with a disc 14 which contacts with the diaphragm 11. If the pressure in the liquid gets too high the diaphragm 11 is depressed and a switch 31 is actuated by descent of the stem 13 to de-energize the pump motor so as to limit the pressure. When the pressure falls the rise of the stem 13 causes energization of the motor. The disc 14 prevents damage to the diaphragm 11 in case the accumulator fills accidentally with liquid, and it also supports the diaphragm. A disc 7 mounted so as to allow of flow of liquid prevents damage to the diaphragm if the liquid is forced completely out of vessel 6.

Filed: 1965-02-22
Abstract: 1,086,624. Discharge apparatus. SIEMENSSCHUCKERTWERKE A.G. Feb. 22, 1965 [March 5, 1964], No. 7657/65. Heading H1D. [Also in Division F1] In a plasma accelerator device, e.g. for use as a space propulsion engine, an MHD generator or as a surface treatment device, the plasma is subjected alternately to Z- and #-pinch compression. In a cylindrical or conical device a magnetic field winding is used to produce the #-pinch; axially spaced electrodes, one having an outlet aperture for the plasma produce the Z-pinch. In a toroidal device both Z- and #- pinches are produced by magnetic coils. At the plasma outlet from the toroidal tube the turns of the #-pinch coil are increased in diameter while the turns of the Z-pinch coil are more closely spaced. In addition, short coils are distributed around the toroid to set up a sequence of mirrorfields to prevent outward drift of the plasma. A circuit is described for automatically triggering the Z-pinch and #-pinch coils in sequence while providing a time-lag phase free of magnetic fields between each Z-pinch and #-pinch phase. The turns in each magnetic coil are connected in parallel and may be constructed in tape form.

Title: A method and apparatus for measuring the thickness of a layer or coating on a body
IPC: G01B7/06
Filed: 1968-02-19
Abstract: 1,212,384. Measuring thickness electrically. B. ZUMBACH [trading as ZUMBACH ELECTRONIC-AUTOMATIC]. Feb. 19, 1968 [Feb. 23, 1967; Aug. 11, 1967], No.7941/68. Heading G1N. The thickness of a layer on a body of different electrical characteristics is determined by a coil connected in an oscillator circuit which is brought into proximity with the body so that the coil and heuse the oscillator frequency, is influenced to an extent determined by the layer thickness, the arrangement being characterized by means for withdrawing the coil to a position, where it is not influenced by the body, for calibration purposes. Two or more coils are used with the oscillators connected in pairs to produce beat frequencies indicative of inequalities in the layer thickness at the regions where the coils are positioned. Reference is made to the use of the invention where one coil responds to a test object and the other to a calibrated reference object but the description is primarily directed to the determination of inequalities in a single object, specifically the insulation of a cable or wire. Figs.2 and 3 illustrate the principle of operation where the wires or cable 1 passes three measuring heads 3, 4, 5, each containing a coil and oscillator, and is guided by passage through notches 7 in plates 6. Two heads 3, 4 are displaced angularly by 90 degrees and the remaining head 5 is symmetrically placed, i.e. at 135 degrees, to each of the first two. The oscillator in head 5 functions as a reference oscillator, beats being formed by reference to the frequencies from heads 3 and 4 to furnish indications with the aid of frequency meters, Fig. 1 (not shown), of the cable insulation thickness in two directions at right-angles. Other dispositions of the measuring heads are referred to. The beat frequency indications are adjusted to be zero when the heads are withdrawn from measuring positions as shown in Fig. 2 to positions where the cable has no influence on the coils. The zero indications may be brought about by adjustment of the oscillator frequencies or by backing off the frequency meter indications with direct current, Fig. 8 (not shown). A detailed construction of an arrangement for withdrawing the measuring heads is shown in Figs. 4-8 (not shown). The heads are supported by parallelogram suspensions and urged by springs into their measuring positions. Cables actuated by a common control for the three heads may pull the heads radially away from the measuring positions. An adjustable stop determines the measuring positions. An arrangement involving spring- loaded heads in casings is described for use where the objected tested is not flexible.

IPC: C07C51/15
Filed: 1937-03-18
Abstract: Purifying sodium phenate by forming at a temperature above about 50 DEG  C. an aqueous solution containing not less than 35 per cent by weight of crude sodium phenate, cooling the solution to not lower than about 50 DEG  C. to precipitate unwanted inorganic salts, removing the precipitate thus formed and cooling the solution further to crystallize out sodium phenate hydrate, which is pure enough to be converted to salicylic acid by the known practice of dehydrating, heating with carbon dioxide under pressure and acidifying.  Sodium hydroxide is preferably present in the sodium phenate solution since it reduces the solubility of sodium phenate.  The phenate may be formed by fusion of benzene sulphonic acid with sodium hydroxide. The mother liquor from the sodium phenate hydrate crystals may be concentrated to yield a second crop of crystals and the solution remaining after their removal used either for conversion of the benzene sulphonic acid to the sodium salt, or after reinforcement with solid sodium hydroxide, for fusion of the sodium salt to produce phenol. Before being so used, the sodium hydroxide solution may be saturated with phenol, e.g. phenol vapours given off during the process, or if desired phenol produced by acidification of the second crop of phenate crystals.
