Title: Improvements in devices for the optical monitoring of the movement of a body
IPC: G01D5/30
Filed: 1958-11-10
Abstract: 895,600. Photo-electric movement detectors, PERKIN-ELMER CORPORATION. Nov. 10, 1958 [Nov. 13, 1957], No. 35960/58. Class 40(7). Movement of a body, e.g. the swayings and twistings of structures e.g. tall buildings and bridges, or the movements of gyroscopically stabilized platforms, is detected by reflecting two beams of light of different colour or differently modulated on to a radiation sensitive device which indicates the relation between the intensity of the beams. In the arrangement shown in Fig. 9 light from arc lamp 20 is focused in a slit 23 and an image of the slit is formed on a mirror 26 via a mirror arrangement 25 or a pentaprism. Two chopping discs 22 interrupt the halves of the beam in antiphase and rotation of mirror 26 causes the relative quantities of the two components of light incident on a photo-cell 28 to vary the difference is defected by a phasesensitive detector 31 fed with a voltage synchronized with the chopping plates and the output is fed to a servomotor 32 which rotates the cell housing until the amount of each beam falling on the cell is equal. In addition, a triple mirror reflects light back through the mirror arrangement to a further photo-cell 29 which similarly controls a servomotor 34 to adjust a plate 30 carrying mirror 25 and the anguiar deflection detecting arrangement sideways until the two light components incident on cell 29 are equal. The translational movement of the plate indicates the translational movement of the body and the angular movement of cell 28 indicates the rotational movement.

Title: Halogenation of phthalocyanines
IPC: C09B47/10
Filed: 1960-10-24
Abstract: Phthalocyanine dyes are brominated by subjecting the dye in a molten mixture of aluminium chloride and another normally solid inorganic halide, said mixture containing an amount of bromine in the form of an inorganic bromide at least equivalent to the desired amount of combined bromine in the brominated phthalocyanine product, to the action of an oxidizing agent having a higher oxidizing potential than bromine under the reaction conditions.  The aluminium chloride and inorganic halide are preferably used in eutectic ratios to give the lowest fusion point.  Preferred inorganic halides are sodium and potassium, chlorides and bromides but ammonium, calcium, magnesium, iron, copper, nickel, antimony and zinc chlorides and bromides are also specified.  Specified phthalocyanines are metal-free and metal phthalocyanines such as copper, iron, nickel, aluminium, chromium, tin, zinc, cobalt or lead phthalocyanine.  Chlorine is the preferred oxidizing agent and after the bromination reaction is completed the reaction may be continued to introduce chlorine atoms.  Also specified as oxidizing agents are air, oxygen, ozone and ammonium and metal bromates, chlorates, nitrates, chromates, persulphates, perborates, arsenates, oxides and peroxides.  In an example a mixture of aluminium chloride and sodium chloride is melted at 160 DEG -170 DEG C., a mixture of copper phthalocyanine and sodium bromide is added and chlorine is passed in below the surface of the melt until all the bromine has reacted and for several hours thereafter to give a product containing 2 Br and 12 Cl atoms per molecule.  Further examples are given. Specification 711,677 and U.S.A.  Specifications 2,833,783 and 2,833,784 are referred to.

Title: Apparatus for producing high frequency alternating currents by means of spark gaps
IPC: A61N1/40
Filed: 1928-12-13
Abstract: 326,534. Scheel, J. E., and Bull, W. H. Dec. 13, 1928. Electric appliances.-In apparatus for producing high frequency alternating current for therapeutic purposes from low frequency supply mains by means of series spark-gaps with auxiliary ignition, resistance regulators, responding automatically, regulate the low frequency supply currents or voltages. Iron-hydrogen resistances or gas discharge tubes, such as glow lamps or the like, may be used alone or in combination with other elements as the resistance regulators. In an example, an iron-hydrogen resistance 3 is connected in the primary circuit of a transformer 4, the secondary of which is connected to the primary high frequency circuit, as shown, and to the middle electrode 5 of the spark-gap through a fixed or regulable resistance 6. To assist the action of the regulator 3, a circuit 10 which absorbs excess energy may be provided, the coupling of this circuit being adjusted by the adjustment of the coupling between the primary and secondary high frequency circuits. Similarly, it is desirable to bring the potential to zero at a point in the secondary high frequency circuit by means of a solid or perforated conducting plate or layer 11 which may be enclosed in a sheath. This plate may surround the internal parts of the apparatus, and if there are several secondary circuits, a plate may be provided for each circuit or for several circuits in common. The secondary high frequency circuit is closed through an insulated lead 12, an electrode 16, the patient, a metal sheath 14 of the holder 13, and an insulated or uninsulated wire 15. Direct contact with the sheath 14 may be avoided by the employment of a dielectric and the sheath may then consist of metal coatings insulated from one another. 17 is a safety spark-gap which may be adjustable.

Title: Improvements in processes and apparatus for concentrating or separating ores
IPC: B03D3/00
Filed: 1959-10-30
Abstract: 941,200. Concentrating ores. O. J. PARKER. Oct. 30, 1959, No. 36936/59. Heading B2H. Minerals are separated at the interface produced between an ore pulp and a selector liquid to which one of the constituents of the ore preferentially adheres. As shown in Fig. 1, a selector liquid, which may be an oil, enters separating compartment 1 through inlet SE and pulp enters through inlet 3. The pulp is caused to flow through compartment 1 in contact with hydrophilic guide plate 5 while the selector flows in contact with hydrophobic plate 7, the configuration of plates 5 and 7 being such as to induce a turning over action at the interface between the two liquids where the selected mineral is separated. Spent pulp is extracted through discharge 6 while the selector flows up plate 13 against downward flowing stream of wash water which enters at W1. The major portion of this water leave at W2, while minor portions accompany the concentrate with the selector through outlet CE, and the tailings through discharge 6. The concentrate is then separated from the selector which may be recycled. In an alternative embodiment (Fig. 2) a mixture of pulp and a gassed selector is drawn up feed pipe 26 into separating compartment 21 which is at a reduced pressure sufficient to cause the evolution of gas in the selector and give buoyancy to the concentrateladen globules which rise through column 22. The selector and concentrate are washed with water supplied to compartment 23 through pipe 29 and leave through pipe 24. A vacuum pump is connected to pipe 28. The selectivity of the process may be controlled by means of additions to the pulp or the selector.

Abstract: 1,026,886. Circuits employing bi-stable magnetic elements; automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Sept. 20, 1963 [Sept. 20, 1962], No. 37079/63. Headings H3B and H4K. A lock-out circuit comprises magnetic storage cores C 1 -C 26 , each having a set winding S connected between a respective input S 1 -S 26  and an inhibit winding i on the next core of higher order, the inhibit windings being connected in series to a common input terminal of opposite polarity. Consequently if an input through a set winding switches the associated magnetic core, the input current through inhibit windings prevents all other cores of higher order from switching while that input is present. The arrangement is applied to a time division multiplex telephone system comprising a plurality of highways each offering 25 time slots. An input S 1  to S 25  is energized if the associated time slot is free, and the first of the free slots is identified by switching of the lowest order respective core C 1 -C 25 . If all the slots are busy core C 26  is switched. The switched core is reset by a pulse from terminal RS 1  through resetting windings r, and an effective output pulse appears at terminals O 1 -O 26 . The arrangement includes terminals D 1 -D 7  for a complementary 3-out-of-7 binary code indication which is applied to groups of inhibit windings x and to a common set winding circuit y. When operative, this arrangement prevents any further switching of that core which was switched and reset to indicate the first free time slot taken into use.
