Filed: 1971-04-19
Abstract: 1310643 Character display tubes SONY CORP 19 April 1971 [19 Feb 1970] 22019/71 Heading H1D An electron tube for character display comprises a substrate, a plurality of indicating units A 1 , A 2  formed thereon, each unit having a plurality of first segmented electrodes E 1  to E 8  arranged in substantially identical patterns, a plurality of second electrodes P 1 , P 2 , P 3  formed on the substrate, at least one barrier electrode C between each pair of adjacent indicating units and a transparent envelope enclosing all the electrodes. The tube may be of the glow discharge type or the segmented electrodes may be coated with luminescent material and irradiated by electrons from a cathode H. Corresponding segmented electrodes of the indicating units may be interconnected within the envelope and the indicating units may be operated sequentially in a time divisional manner. Instead of one barrier electrode which surrounds all the indicating units a separate electrode may be provided between each adjacent pair of units in which case a further second electrode may be provided surrounding each set of segmented electrodes, Figs. 3 and 7 (not shown). In the case of a glow discharge device the barrier electrodes are kept at a potential such that interference between adjacent indicating units does not arise and that the barrier electrodes themselves do not give rise to a discharge. In the luminescent type tubes the barrier electrodes are held at substantially the same positive potential as those segmented electrodes which are to be displayed. In a preferred construction the segmented electrodes and the second electrodes are printed on the substrate together with their interconnecting conductors 3, 4, a layer of dielectric, e.g. glass frit, is deposited thereon and the barrier electrodes then provided on the insulating layer.

Abstract: 961,226. Hydraulic apparatus. ELECTRO-HYDRAULICS Ltd. June 19, 1962 [June 19, 1961], No. 22120/61. Heading F1P. Means for monitoring the support units of a power operated roof support system comprises means selectively to connect each roof support unit to indicating means, and switch means associated with each support unit to be operated dependent upon its condition and which in the event of a fault occurring in a support unit operate to halt the operation of the selecting means so that selection of the support units stop with the indicating means indicating the faulty unit. The means for monitoring the support units includes, in addition to the control system shown in Figs. 1 and 2 of Specification 961,225, a monitor position for the master switch 30, an additional circuit connecting in parallel switches S7, S8, PS1, PS2 which are normally open, an impulse unit 116 and relays A2, A3: switches PS1, PS2 close if the pressure in the props drops and switches S7, S8 close if the props extend to their full extent when they may not be supporting the roof. The relay A2 has rectifiers 107, 109 which permit its actuation only when the switch 30 is moved to the monitor position, and the relay Al which is actuated when the switch operated by the full extension of the advancing ram for the support unit is closed has rectifiers 110, 111 which permit the relay A1 to be actuated only when the switch is in the automatic or manual position. When the switch 30 is moved to the monitor position, a circuit is completed through the banks B1, B3 of the uniselectors US1, US2 to energize relay A2 closing a contact A2/2 in the circuit including the switches normally open contacts of switches S7, S8, PS1, PS2. A circuit is also completed through the impulse unit 16 which stops the wiper arms of uniselectors from one position to the next to sequentially energize the relays A2 associated with the support units and illuminate the associated lamps of the indicator 50. If a fault has occurred in one of the units, one of the switches S7, S8, PS1, PS2 associated with that unit closes to energize the relay A3, the contacts of which close a holding circuit for the relay and de-energize the impulse unit so that monitoring stops with the lamp of the faulty unit illuminated. Other switches may be included in the circuit to indicate faults in the advancing mechanism of the units. The Specification also includes a description of the monitoring system described with reference to Figs. 3A and 3B of Specification 961,225.

Title: An improved manufacture of oxidation products of paraffin wax
Filed: 1931-08-08
Abstract: Oxidation products of paraffin wax, such as fatty acids, anhydrides, aldehydes, and ketones are obtained by hydrogenating hydrocarbon oils, particularly heavy oils, containing paraffin wax, and oxidizing the hydrogenated wax in the presence of the oil.  Oils poor in waxy constituents may be hydrogenated, the fatty acids formed being separated, and the unoxidized oil again submitted to hydrogenation and oxidation.  Hydrogenated wax-containing oils, for example, a hydrogenated hydrocarbon oil of the lubricating type, from which a portion of the oil has been removed may also be employed, the oil recovered from the oxidation product being used, if desired, as a lubricating oil.  The process may be carried out by passing the oil in admixture with hydrogen through a heating zone in which it is heated to about 700 DEG  F.  The heated mixture is led into a reaction chamber heated to a temperature above 650 DEG  F., preferably about 750 to 800 DEG  F., at a pressure of over 25 atmospheres, for example, 200 atmospheres or more.  The hydrogen may be passed directly into the reaction chamber, or part may be passed directly thereto and part sent through the heating zone.  A suitable hydrogenating catalyst may be employed, such as mixtures of the oxides of chromium and molybdenum, or of tungsten and molybdenum, or of other 6th group metals, preferably in admixture with oxides of magnesium, zinc or 3rd or 4th group metals.  The reaction products leave the reaction chamber in such a manner as to interchange heat with the incoming material, and pass to a separating and condensing drum where liquid products are separated for the oxidizing treatment. The oxidation is carried out at atmospheric or higher pressures and at temperatures above 250 DEG  F., preferably about 350 DEG  F. or higher, and cooling means are employed.  The volatile acids formed are absorbed, for example, in a tower packed with active charcoal.  A hot inert gas may be blown through the oil during the oxidation to effect simultaneous distillation thereof.  The remainder of the acids formed may be removed by distillation or by saponification and extraction.  Oxidation catalysts which may be employed are stearates of manganese, zinc, or aluminium, manganese dioxide, potassium permanganate, kerosene, comminuted hard coke, or the oxidized wax itself.  An example is given.
