Filed: 1948-04-30
Abstract: 655,119. Automatic exchange equipment. SIEMENS BROS. & CO., Ltd., and LONG, D. P. April 30, 1948, No. 11838. [Class 40 (iv)] In an impulse counter comprising a highspeed relay PX, a chain of counting relays CA, CB and a common impulsing circuit, and wherein in order to prevent one impulse from operating more than one counting relay the high speed relay is actuated by a transient condition obtaining during the operating movement of a counting relay to open the impulsing circuit, the high-speed relay is energized over two metallic circuits during the period between the closing of the impulsing circuit and the occurrence of the transient condition, one of the metallic circuits being independent of the impulsing circuit. As shown in Fig. 1, the relay PX operates when the starting contact b is closed and, when the impulsing contact p closes, is energized over resistance YB and also over the winding I of relay CA until the closure of an early contact ca1 releases it. As shown in Fig. 2, relay PX has two opposed windings I, II and, on the closure of the impulsing contact p, winding I is energized in series with a counting relay and winding II in series with a coil RC similar to a counting relay. During the operation of the counting relay, winding I is shunted and PX opens the impulsing circuit.

Abstract: 1,086,964. Spacing articles on endless conveyers. NATIONAL BISCUIT CO. March 19, 1965 [March 25, 1964], No. 11858/65. Heading B8A. Randomly spaced articles A fed to an endless belt conveyer 12a are regularly spaced by members 50 of spacing assemblies 47 attached to an endless multiple chain assembly 44, the members 50 moving adjacent and slower than the belt 12a in either an inoperative position, in which the member 50-is locked in an upper position out of the path of the articles, a conditioned position in which the member 50 is in a position to be contacted by the next article A<SP>1</SP>, or an operative position in which the member 50 has been engaged by the article A. Each spacing assembly 47 comprises a mounting plate 51 pivotally supporting at 63 and 73 a series of pivotally interconnected links 62, 70, 71, 72. The link 70 of a first spacing assembly carries a spacing member 50 and has in its leading edge, a recess 84 which is engaged by the link 71 of the preceding assembly 47 to hold the said first assembly in the inoperative position. As the link 71 of said preceding assembly 47 is withdrawn from the said recess 84, the said first assembly linkage gravitates into the conditioned position where links 62, 72 rest on stops 82, 83. The member 50 of.this conditioned assembly is then engaged by the next article A causing the link 70 to be pushed on to a stop 81 and further pivoting of the links whereby link 71 is moved out of engagement with the recess 84 of the next succeeding assembly 47 to condition the same. In operation, providing there is a constant supply of articles engaging the spacing members 50, the articles are continuously spaced and conveyed on to a discharge conveyer. If, however, there is a shortage in articles being supplied by the belt 12a, rollers 75 on assemblies 47 are left in their upper inoperative position and engage a microswitch 95, which through a relay, conditions a solenoid-operated pawl to operate a clutch in the spacing conveyer drive to stop said conveyer when the leading inoperative assembly reaches the downstream sprocket of the spacing conveyer. The switch 95 remains active until all the assemblies 47 between the said sprocket and the switch are engaged by articles, the switch being movable to predetermine this number. A further switch (110), Fig. 2 (not shown) in the relay holding circuit, is opened once per revolution of a constantly driven cam, the one revolution being synchronized with the time taken for the spacing conveyer to move between the switch (95) and the downstream sprocket. Hence the clutch pawl solenoid will be de-activated cyclically provided switch 95 is not closed. The rollers 75 engage guides at the ends of the conveyer runs whereupon the assemblies 47 are guided into their inoperative positions.

Abstract: 844,154. Electric cooking ovens. RADIO HEATERS Ltd. April 11, 1957 [Jan. 24, 1956], No. 11948/57. Divided out of 844,152. Class 39(3). A cooking oven includes high frequency dielectric heating means and comprises a removable shelf or tray which constitutes an electrode of the dielectric heating equipment. As shown, an oven comprises two metal shelves 18, 20 which constitute balanced electrodes and are supported on runners 14 provided on an oven lining 12 of low loss electrically insulating material, e.g. hard glass. An oscillator controlled by a switch 10 is contained within a section 8 of the oven and is capacitively coupled to the electrodes by feed plates 26, 28 which coact with flanges 22 formed on the electrodes, the wall of the oven constituting the dielectric of the coupling. The electrodes may be of perforated metal or of wire mesh and may be dished to form cooking trays. Alternatively, they may be shaped to produce an intense field between central portions 32, 34, Fig. 3, or for uniform heating of food such as a chicken or a joint of meat, they may be shaped as shown in Fig. 4. To vary the heat supplied to the oven, the feed plates 26, 28 are pivoted about an axis 30, thereby varying the coupling between the oscillator and the electrodes. An electric motor operating through a worm drive and a rack may produce the rotary movement of the feed plates. The inner walls of the oven may have irregular surfaces between the two electrodes to minimise dielectric heating of these walls. Instead of capacity coupling the coupling between the electrodes and the generator output circuit may be by contact through metallic conducting guides insulated from the walls of the oven or mounted in insulated walls of the oven. The oven lining may be of metal, the electrodes then having insulating extensions which engage the supporting runners or insulate the electrode from the metal lining. One of the electrodes may be earthed or if a single electrode is used, the frame of the oven is earthed. The oven may also include infra-red or hot air heating means. As shown, a heating element 36 is preferably bolted to the outside of a metal screening shell. Specification 844,153 also is referred to.

Title: Improvements in or relating to Fluid Operating Relay Valves, suitable for use in or in connection with Apparatus for Producing or Reproducing Sound, for Recording Sound and for Signalling and other purposes.
Filed: 1918-07-24
Abstract: 130,148. Baynes, F. W., Gaydon, H. A., and Creed & Co. July 24, 1918. Sound-magnifying appliances.-In a fluid-pressure relay valve for sound amplifying purposes, of the kind having an air-way of grid-like form engaged by a flexible cover member, the flexure necessary to secure vibration in the air-way is magnified by being obtained through pressure exerted endways on the flexible member. The relay is shown in connexion with the stylus-bar of a sound-reproducing machine, but is stated to be applicable for any purpose where a small movement controls the passage of a fluid for producing suitable effects, as in telegraphic and telephonic circuits. In the valve shown in Fig. 1, the flexible member is in the form of a thin strip on ribbon b coacting with the concave or convex edges of a number of thin plates c separated by plates d, d<1> of a triangular form arranged, alternately in reversed order so as to constitute two separated sets of air passages, which are only connected when the member b is moved away from its seat. The compressed, fluid from the inlet pipe g generates sound vibrations by its passage through the valve to the outlet h according to the movements of the member b caused by endways pressure of the stylus-bar k. Another flexible member b may be arranged to engage the opposite edges of the plates c, and the plates may be replaced by a long ribbon bent so as to form a zig-zag valve seat. In a modified construction, the valve seat is formed by a curved plate having slots or openings engaged by a number of narrow ribbons or wires, the pressure fluid passing from the outside through the two sets of openings when the ribbons or wires are flexed. Fig. 17 shows another modification in which the slotted valve seat a<5> may be of truncated, conical, or ogival shape with a circular, rectangular, or polygonal cross-section. The flexible member consists of ribbons or wires b<2>. In the construction shown in Fig. 23, the fixed valve seat is dispensed with, and a pair of flexible bowed ribbons a<6>, b<6> or wires are used. In another form, three or more bowed ribbons are arranged to form a closed hollow body, an endways pressure on the ribbons opening the body along its edges and thus permitting the passage of the fluid. Instead of the flexible member directly engaging the grid or valve seat it may carry by a rod or link a rigid valve member.

Title: Preparation of granular polyvinyl ethers
IPC: C08L29/10
Filed: 1946-04-18
Abstract: Granular rubber-like polyvinyl ethers are made by polymerizing a vinyl ether, such as n-butyl, isobutyl, or isopropyl vinyl ethers, dissolved in an inert non-polar solvent, e.g. propane, by means of an acid-reacting catalyst, e.g. boron trifluoride or its ethyl ether complex, at low temperature, wetting the polymer, while still wet with solvent, at a temperature below that at which it is soluble in the solvent, with a polar liquid miscible with the solvent and which swells, but does not dissolve the polymer, removing the solvent at a temperature below that at which the polymer loses its form and while the polymer is still wet with the polar liquid and finally drying the polymer by removing the polar liquid.  Suitable polar liquids are methyl, ethyl, propyl and butyl alcohols; acetone and methyl ethyl ketone; the monomethyl and monobutyl ethers of ethylene glycol.  The polar liquid may be a mixture, e.g. acetone and water, and may include a quenching agent for the catalyst, e.g. ammonia, and a stabilizer, e.g. diphenylamine, n-butyl monoethanolamine or hydroxy phenyl morpholine.  Before addition of the polar liquid, the non-polar solvent may be partially removed, e.g. by filtration or vaporization at low temperature.  U.S.A.
