Title: Improvements in or relating to methods of manufacturing welding electrodes having two or more flux coats
IPC: B23K35/40
Filed: 1962-06-08
Abstract: 957,388. Making welding electrodes. GEBR. BOHLER & CO. A.G. June 8, 1962 [June 24, 1961], No. 22328/62. Headings B3A and B3R. In a welding electrode having a multi-layer coating the inner layer is applied by extrusion and subsequent layers are applied by spraying. If the layer to be sprayed is in a condition suitable for dipping the spraying is effected with the electrode in horizontal position preferably after the extruded layer has been dried. If the layer to be sprayed is relatively dry and so in a condition unsuitable for dipping the spraying is effected immediately after the extrusion.

Title: Manufacture of vat-dyestuffs
IPC: C09B7/08
Filed: 1929-07-22
Abstract: 316,099. I. G. Farbenindustrie Akt.- Ges. July 21, 1928, [Convention date]. Indigoid dyestuffs are obtained by condensing a reactive aderivative of isatin with an N- alkyl-1 : 2-oxybenzocarbazol. In an example, N- methyl-1 : 2-(1<1>-oxybenzo) carbazol is condensed with isatin-a-anilide in the presence of acetic anhydride. The dyestuff dyes wool and cotton, from a vat, a yellow tint, which turns deep black when exposed to air. Their great aflinity for the fibre renders the dyestuffs suitable for printing. Specification 22287/13 is referred to. N-methyl-1 : 2-(1<1>-oxybenzo) carbazol is prepared by condensing unsym-methylphenylhydrazine with 1: 5-dihydroxynaphthalene. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the condensation of isatin a derivatives with any oxybenzocarbazol N substituted derivative. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1,179,238. Semi-permeable membrane of cellulose acetate. COURTAULDS Ltd. 19 May, 1967 [20 May, 1966], No. 22524/66. Heading B5B. [Also in Divisions B1 and C3] A semi-permeable membrane for desalination of water is prepared by forming a solution of cellulose acetate in aqueous acetic acid containing 5-25% of water by weight, casting as a film of uniform thickness and removing the acetic acid by immersing in water to effect coagulation of the film. Other water-soluble pore-forming agents may also be added e.g. polyvinyl alcohol or agents soluble in the aqueous acetic acid solvent e.g. methyl and hydroxyethyl cellulose. The cellulose acetate preferably has an acetyl content of 52-56À5% by weight. It is advantageous to separate the coating and coagulation steps by at least 5 minutes. The membranes of the example were heat-shrunk by immersion in hot water to yield more efficient membranes for desalination.

Title: Improvements in or relating to automatic locks for doors, particularly the doors of lifts and like shafts
IPC: E05B65/00
Filed: 1924-09-24
Abstract: 243,478. Elliston, E. R. Sept. 24, 1924. Catches yielding to pull and pressure.-A pin 2 on the hinged or sliding door of a lift well, escalator, train, &c. co-operates when the door is closing with two spring-controlled forked or notched levers 10, 11 on the door frame A which form a yielding catch to close and secure the door and to control an electric circuit such as the main circuit in the case of a lift. The levers may be locked by the movement of a lift cage. The levers, latch and switch are mounted as a unit on a base 1 as shown in plan in Fig. 3 and in elevation in Fig. 2. As the door closes, Fig. 4, the pin 2 engages the forked ends of the levers 10, 11 which are pivoted at 5 and are urged towards either extreme position by springs 12, 13 so as to snap over when past their dead centres. The lever 11, loose upon the spindle 5, forces the door home and holds it closed, whilst the lever 10, fast on the spindle 5, closes the switch 7, 8. When the lift cage is moved, a cam C disengages an arm 19 on a shaft 17, allowing the shaft to turn under the action of a spring 17<a>, bringing a latch arm 16 on the shaft into position to lock the levers 10, 11, as shown in Fig. 2, but with sufficient play to allow for warping or springing of the door. The parts are arranged so that when the switch is closed the levers are in position to be locked by the latch, and so that the play between the levers and the latch does not break contact at the switch.

Title: Firing control unit for a current converter
IPC: H02M7/00
Filed: 1971-04-19
Abstract: 1351633 Controlling converters SIEMENS AG 19 April 1971 [4 March 1970] 23131/71 Heading H2F [Also in Division G3] A firing angle control system for a converter comprises an oscillator including a comparator responsive to actual and desired values of an electrical parameter, a resettable signal generator 14 for generating a signal which rises with time and is periodically reset, a threshold stage 10 operable each time it senses a predefined relationship between the comparator output and the signal from 14 to reset generator 14 by a constant amount. The phase of the oscillator is thus a function of the error between desired and actual values. As shown, the current in a load 5 from a threephase bridge of thyristors 1 is monitored at 6 and compared with a reference current Is. After amplification at 7, the error voltage Us is used to control the threshold of a boundary value stage 10. A free-running sawtooth oscillator comprises an integrator 14 which generates a ramp from a unidirectional voltage Ue, each ramp being terminated when the threshold value of the boundary value stage 10 is reached. At this time, a pulse is emitted by stage 10 which is passed by an AND gate 33 and an OR gate 38 to a monostable circuit 16 which resets the integrator 14. The phase of the oscillator formed by stages 10, 14, 16 is thus a function of the error signal Us. Each pulse from the monostable stage 16 steps a ring counter comprising bi-stable trigger stages 20a ... 20f which provides six trains of pulses to feed amplifiers 22 which supply trigger pulses to the thyristors 3a ... 3f. Upper and lower limit control.-Six-phase synchronizing voltages are derived from the three-phase mains RST by means of a synchronizing transformer 23 each secondary of which feeds a separate threshold stage 25a arranged to provide 180 degree pulses to AND gates 27a, 27b which provide 60 degree pulses for control of the upper and lower limits of the conduction angle. The lower limit is determined by the feed of 60 degree pulses via AND gates 29a, 29f and OR gate 31 to control the AND gate 33. The upper limit is similarly determined by a monostable stage 41 which feeds an extra pulse via OR gate 38 where necessary. Overall control.-A resistor 42 is arranged to shunt the integrator capacitor 13 so as to provide curvature in the lower of the integrator 14 and provide an overall control of proportional plus integral form.
