Title: Improvements relating to the refining of heavy hydrocarbons
IPC: C10G45/08
Filed: 1946-09-06
Abstract: Heavy hydrocarbons boiling above about 570 DEG  F. such as wax distillates and asphaltic residues, are desulphurized without substantial alteration of boiling point by passing them in the liquid phase with sufficient hydrogen to satisfy the sulphur removal and the solubility of the hydrogen in the liquid feed over hydrogenation catalysts at a pressure of 800 to 1000 lbs. per sq. inch, and at a temperature between 750 DEG  F. and 820 DEG  F., the space velocity being maintained between 0.6 and 2.0 v./v./hr, whereby a substantial proportion of the sulphur is converted into hydrogen sulphide which is removed from the treated fraction in known manner.  The catalyst is preferably of the cobalt molybdate type deposited on alumina. Other catalysts such as oxides or sulphides of nickel, cobalt, chromium, molybdenum, copper, manganese, and tungsten, metals such as sodium, potassium, lithium, calcium, zinc, aluminium, manganese, iron nickel, cobalt, and copper, or compounds such as molybdates, thio-molybdates, or thiotungstates, may be used.

Title: Improvements in refrigerating apparatus
IPC: F25B17/00
Filed: 1921-10-11
Abstract: 188,887. White, A. E., (National Auto matic Refrigerator Co.). Oct. 11, 1921. Refrigerating, absorption machines for; cold-accumulators. - Apparatus working on the reversing system comprises a generator-absorber 1, a condenser and receiver 7, and an evaporator 11 in a brine tank 12. The receiver 7, and evaporator 11 communicate through a capillary tube 10, the generator-absorber and the condensing coil 20 through a one-way valve 9, and the evaporator and generatorabsorber through a one-way valve 14. Electric circuits are arranged to be made and broken, according to the height of the liquid ammonia in the receiver 7 which operates a float 31 to control the supply of heating-medium or of cooling-water to the generatorabsorber or of cooling-water to the condenser. A valve 17 in the cooling- water supply-pipe admits water either through a pipe 16 to the generator cooling coil 18, or through a pipe 19 to the condenser cooling coil 20, a time switch 30 releasing those parts that determine which circuit is to be traversed by the cooling-water. The parts are positively moved to the operative position through electric means actuated by the movement of a swinging beam (not shown), carrying the switches 28, 29, 30, the position of the beam being controlled electrically by the level of the liquid ammonia in the receiver 7 and determining also which electric circuit is made or broken. When the receiver 7 is nearly empty the electromagnet 26 is energized and the swinging beam is thereby caused to open the switch 29 and to close the switch 28, causing the generator-absorber to be heated by the wire 2 and cooling-water to flow round the condenser. After a pre-determined interval, the time-switch 30 breaks the circuit flowing round the armature 40 controlling the water-valve 17, thus leaving it in such a condition that on subsequent movement of the beam, when the receiver 7 is full, water is cut off from the condenser and caused to flow round the generator-absorber. When the receiver 7 is full, the switch 28 is open, thus cutting off the heat from the generator, and the switch 29 is closed, thus energizing the electromagnet 46 to operate the water-valve 17 until such circuit is broken by the time-switch 30. A direct return connection between the evaporator and the generator-absorber may be provided, as shown in Fig. 2. Ice-making, can or mould apparatus for; refrigerators, domestic.-Fig. 3 shows the application of the apparatus to a domestic refrigerator, in which ice blocks 53 are formed in drawers 51 in a brine tank located at the top thereof.

Title: Improvements relating to piezo-electric devices
IPC: H03C3/28
Filed: 1926-11-02
Abstract: 284,761. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). Nov. 2, 1926. Piezo-electric units; thermionic generators; undesired signals, eliminating.-A piezo-electric device has means for adjusting the natural frequency. A piezo-electric crystal PE is supported on a fixed electrode L1 and the natural frequency adjusted by varying the air gap between the crystal and a movable electrode L2. As shown the crystal is associated with an oscillating-valve V2 to control the frequency of oscillation. The order of the resonant frequency of the crystal utilized is varied by making the reactance of an output circuit W inductive or capacitative, and a fine adjustment of the frequency then obtained by adjusting the air gap. Interfering signals may be eliminated in reception by shunting through a circuit containing a piezoelectric device adjusted to the same frequency by varying the air gap. If the interfering frequency is outside the adjustment range of the crystal, it is brought within the range by modulation or heterodyning. Specifications 275,581 and 277,330 are referred to.
