Title: Improvements relating to electrical signalling apparatus
IPC: H04M11/00
Filed: 1940-02-15
Abstract: 536,122. Electric signalling systems. GENT & CO., Ltd., and REMINGTON, C. Feb. 15, 1940, No. 2898. Addition to 493,203. [Class 40 (i)] [Also in Group XXXIX] The system of the parent Specification wherein liquid-level indications are transmitted as audible signals over a telephone line is modified by making the signalling circuits dependent on contacts closed by the liquid at predetermined levels. As in the prior arrangement, when an enquiry call is made, a vibrating relay causes the handset to be lifted and maintains the circuits in signalling condition for a given time. In one arrangement, Fig. 1 (not shown), a pair of relays are controlled respectively by high level and low level contacts, each of which may comprise two strips of stainless steel clamped to an insulator. Different signals, for example, continuous buzzer, intermittent buzzer, bell, are connected up according as the liquid level is below the lower contacts, above the.lower but below the higher contacts or above the higher contacts. In a second arrangement, Fig. 2, four contacts E1-4 at various levels are connected to corresponding sluggish relays A1-4 which are arranged to energize and subsequently release in sequence, and a pair of bells B1, 2 are given an impulse alternately as each relay releases, so that the enquirer hears a number of strokes equal to the number of contacts submerged. The cycle of operations is repeated after a delay imposed by the energization and release of two sluggish relays R1, 2 aslong as the vibrating relay 6 continues to operate.

Title: Process for the continuous distillation of magnesium
IPC: C22B26/22
Filed: 1933-02-02
Abstract: 412,664. Distilling magnesium. OESTERREICHISCH AMERIKANISCHE MAGNESIT AKT.-GES., Radenthein, Austria. Feb. 2, 1933, Nos. 3218 and 3219. Convention dates, Feb. 11, 1932 and Jan. 17, 1933. [Class 82 (i).] Magnesium is continuously distilled under reduced pressure by passing material high in magnesium through a heated chamber and carrying the vapours by a non-oxidizing gas through a filter into a condenser where they are suddenly cooled, measures being taken to prevent the vapours from condensing on their way to the condenser. Filtering may be replaced by reversing the direction of flow of the vapours or reducing their velocity. The crude magnesium passes progressively through a heated device such as a tube 1 containing a worm conveyer charged from a vessel 7 provided with a lock chamber 4 and discharging into a residue collector 10 also provided with a lock chamber, pipes being provided to connect these various containers to a vacuum pump. Magnesium vapour from the chamber 1 condenses on an internally cooled tube 17. By arranging a receiver 15 provided with an outlet valve more than 6 metres below the condenser an automatic outlet device is obtained. Alternatively, two receivers connected with the condenser by valve controlled pipes may form the collecting device. A filter 20 of sintered magnesite granules or coal slack removes the dust from the vapours. Pipes 28 at various points in the system supply inert or reducing gas, such as hydrogen, to direct the flow of the magnesium vapours. The filter 20 may be replaced by a cylindrical dust precipitating chamber into which the vapours are led tangentially. The Specification as open to inspection under Sect. 91 describes also a method in which the material to be treated is passed through a vertical heated tube by means of a chain of buckets. This subject-matter does not appear in the Specification as accepted.

Patent GB-360763-A (GB)
Title: Improvements in and relating to methods for automatically starting steam turbines
IPC: F01D19/00
Filed: 1931-02-03
Abstract: 360,763. Steam turbines. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin. ) Feb. 3, 1931, No. 3456. Convention date, Feb. 3, 1930. [Class 110 (iii).] In starting a steam turbine the actuation of a primary member automatically or manually sets into operation a series of starting operations in dependence on the physical conditions occurring with the setting into operation of steam turbine plants. In the arrangement shown, the primary member consists of a switch 2 which is thrown over when the voltage in the system to which the generator driven by the turbine 13 is to be connected falls below a predetermined value. This causes an auxiliary prime mover 3a to be started up to set into operation the condensate pump 3b, the cooling water pump 3c, and the pump 3d for the jet apparatus 4 of the condenser 5. When a predetermined vacuum has been created an automatic device 6 attached to the condenser causes a valve 7 in the steam line to open so that steam is supplied to a turbine driving an auxiliary oil pump 8. This pump feeds the main bearings, and when the outflow from all of the bearings, as measured by devices 9 reaches a predetermined amount, a valve 10 is actuated to pass pressure oil to the servomotor 11 of the main stop valve 12. The turbine is thereby started up, and when the shaft begins to turn a contact g on its end acts to open a valve 15 which passes steam to seal the outer stuffing-boxes. The main oil pump 16 now comes into operation to supply the oil pipe lines. It delivers at a pressure greater than that of the auxiliary oil pump 8 and causes a non-return valve 17 to close, whereupon the valve is closed and the auxiliary oil pump is shut down. At the same time the speed governor 19 takes over the control of the regulating valves 18. Means may be provided for preventing excessive supply of steam during the preliminary heating up of the rotor and casing. These means depend upon the movement over contacts of a pivoted lever which follows the differential movement of the rotor and casing due to expansion. A pressure responsive device connected to the condenser may act upon the pilot valve of the servomotor 11 in order to limit the supply of steam upon increase of the condenser vacuum. The same result may be secured by the use of a motor-driven cam, and the actuation of this cam may be associated with the heating-up control referred to above. The whole operation may be controlled by a contact drum, and a pressure responsive device actuated by the oil may be provided to cut out the control.

Title: Process for recovery of high purity hydrocarbons
Inventor: CORNEIL HAMPTON GASKILL
IPC: C07C7/14
Filed: 1958-02-04
Abstract: A cyclic hydrocarbon crystallizable from a feed stock at a temperature of -50 DEG  to -120 DEG  F. is recovered by dissolving the feed stock in 0.5 to 1.5 volumes, per volume of feed stock, of a liquefied, normally gaseous refrigerant, chilling the solution by autorefrigeration to a temperature of -50 DEG  to -120 DEG  F. to form a slurry of crystals in a mixture of liquefied refrigerant and mother liquor, turbulently isothermally filtering the slurry, recycling the slurry to the chilling zone, adding more refrigerant, continuing this process until 90 to 99% of the mother-liquor is removed, and then separating the hydrocarbon from the refrigerant. The cyclic hydrocarbon may be durene, paraxylene, benzene, cyclohexane or naphthalene.  The refrigerant may be ethane, ethylene, propane, propylene, butane, butylene, methyl chloride, sulphur dioxide, dichloro-ethane or dichloropropane.  The slurry may be warmed by a temperature of 20 DEG  to 50 DEG  F. for 15 minutes to 1 hour subsequent to the chilling step, and then chilled to the crystallization temperature again before the turbulent isothermal filtration.  During the chilling step liquefied refrigerant may be added, if desired, to replace that lost in the autorefrigeration. During the filtration step the volume of liquid in the slurry may be kept constant, the volume of refrigerant may be kept constant, or the ratio of the volume of refrigerant to the volume of mother liquor may be kept constant.

Abstract: 1,197,272. Semi-conductor devices; printed circuit assemblies. FERRANTI Ltd 23 Jan., 1969 [26 Jan., 1968]. No. 4090/68. Headings H1K and H1R. Bonding pads on a passivated integrated circuit wafer are bonded to conductors, which may be disposed on an insulating substrate, through conducting pillars formed on raised portions of the wafer or substrate. A typical assembly, Fig. 4, is formed by etching in the surface of a glass wafer a recess 19 with raised pedestals 18 on its base. After evaporating layers of nickel-chromium alloy and gold over the recessed face and pattern etching the gold to define tracks terminating on the pedestals gold is thickly plated on the gold tracks from a salt solution using the alloy layer as electrode to form a layer 13 which on the pedestals defines the conducting pillars 16. Finally the alloy between the gold tracks is etched off in cerric sulphate solution. The pillars are then bonded by ultrasonic or thermocompression techniques to the gold coated contact pads of an oxide passivated silicon circuit wafer 12. In an alternative method the ends of the conductive tracks bearing the pillars are cantilevered to permit differential expansion to be taken up. This is achieved by copper plating areas terminating at the pedestals prior to deposition of the nickelchromium alloy and etching to remove the copper before bonding. In another embodiment the pillars are formed on the silicon wafers by pattern etching the wafer surface before passivation, after which a pattern of conductive tracks of gold on molybdenum is formed substantially as described above. The pillars on such a wafer may be bonded to conductors of a lead frame assembly which may be fixed to an insulating substrate. If it is not the bonded assembly is potted in resin prior to severing the leads from the frame. The metal deposition and pattern etching steps may be replaced by the single step of masked deposition.
