Title: Improvements in fiashing lamp control circuits
IPC: H05B41/30
Filed: 1958-09-05
Abstract: 855,941. Switching systems; charging and discharging capacitors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 5, 1958 [Sept. 9, 1957], No. 28592/58. Class 38 (4). A lamp control circuit supplies, in response to an input signal, cyclically recurring electrical pulses to a lamp, which on ignition delivers an output signal which terminates the input signal. A positive input signal from say a computor is applied to the grid 10 of a valve T1 which conducts, energizing a relay coil R1 which closes a pair of contacts a connecting a capacitor 12 to a pulse transformer primary winding 13, the secondary winding 15 of which is connected to the ignition electrode of the lamp L. If the lamp L flashes, a capacitor 16 is discharged through the lamp causing a potential to appear at a terminal 18 which is fed back to the computer which removes the input signal. If the lamp does not flash, a capacitor 19 discharging at the same time through another pair of contacts b extinguishes normally conducting neon tubes 23 connected to the control grid 21 of a valve 22 turning it off; which removes the screen potential from a grid 24 of the valve T1 turning this off also, releasing the relay R1 which allows capacitor 19 to recharge and hence re-energize the relay R1 ab through conduction of valves 22, T1, this sequence being repeated until the lamp L flashes, causing the input signal to be removed.

Patent GB-603810-A (GB)
Title: Hydrolysis of acetone auto-condensation products
IPC: C07C45/67
Filed: 1945-10-30
Abstract: Acetone and isophorone are made from acetone auto-condensation products which do not contain more than 10 per cent of isophorone or lower-boiling compounds, by heating such products with an aqueous solution containing .5 to 25 per cent of an alkali metal hydroxide at a temperature of 130-235 DEG  C.  The hydroxide is preferably sodium or potassium hydroxide, or may be lithium, rubidium or caesium hydroxides or mixtures thereof.  The preferred concentration of hydroxide is 1-10 per cent, and the preferred temperature range 170-220 DEG  C. and higher ketones of the general formula C3nH4n+2O, which may be used separately or together, and may be prepared by autocondensation of acetone with alkaline catalyst (see Specification 583,863), acids (e.g. hydrochloric and sulphuric), by vapour phase methods as described in Specification 525,142, or by catalysts such as alkaline earth hydroxides, sodium alcoholate, calcium carbide, sodium amide.  The process may be batchwise or continuous, and the reactor may be fitted with a fractionating column, whereby an azeotropic mixture of acetone and water may be withdrawn.  In examples: (1) acetone was heated under pressure with aqueous potassium hydroxide, and the organic products obtained were fed to a continuous distillation column under pressure together with more potassium hydroxide solution to reconvert the diacetone alcohol and mesityl oxide formed to acetone.  The organic products were then fractionally distilled, and the fraction of higher boiling point than isophorone was heated under pressure with potassium hydroxide, which treatment effected an increase in the proportion of acetone and isophorone of about 13 per cent.  In a further example: (2) a fraction of the high-boiling ketones boiling between 123-142 DEG  C. at 10 mm. pressure was heated under pressure with potassium hydroxide solution, the treatment causing about 31.5 per cent hydrolysis to acetone and isophorone.

Abstract: 351,351. Lubricating casting-moulds. SANDRINELLI, F., 9, Freieckweg, Berne, Switzerland. Sept. 26, 1930, No. 28939. Convention date, Oct. 7, 1929. [Class 12 (iii).] A lubricating-device for the moulds of singletype composing and casting machines comprises an oil container, serving as a pre-heater, from which oil is delivered drop-wise upon the conical walls of inlets, which communicate by conduits with the mould, so that the oil flows in continuous threads through the conduits. The container 1, Fig. 1, preferably of copper, is supported by a plate 2 from the bridge 4 of the machine, a three-sided stem 5 on the container engaging a triangular hole in the plate. The container has a venting-passage 8, controlled by a valve 7, and is heated by two rods 11, clamped to it by collars 10, and immersed in the molten metal of the machine. The oil drops from three outlet-tubes 14, controlled by needlevalves 15, into three conical passages 21 in a distributer-head 22, from which conduits 25 lead to the mould. The passages 21 are eccentrically located with respect to the dropping-tubes 14, so that the oil falls upon the sides of the passages, and not directly into the holes. The eccentric position is secured by means of a gauge 20, Fig. 7, having eccentrically arranged pins 20<1>, 20<11>, one of which is inserted in a central hole in the head 22, and the other in the triangular hole in the plate 2. The conduits 25 are connected to the head 22 and to the mould by conically-ground surfaces. A collar 27, having resilient braces 26, connects the head to the conduits.

In a heavy water moderated carbon dioxide gas cooled nuclear reactor the gases released by a fracture of the coolant circuit are contained within a concrete enclosure. The latter is formed of the reactor biological shield connected by flues to a chamber external to the shield and open to the atmosphere at the end remote from the reactor. Upon fracture of the coolant circuit the released gas flows into the reactor enclosure and through the flues into the external chamber by displacement of air. Discharge of the gases to the atmosphere is prevented by a fan extraction filter system coupled to the external chamber and which establishes a counter-flow through a sonic throat to a filter bank and exhaust stock.

Abstract: 1374462 Casting composite articles DEFENCE SECRETARY OF STATE FOR 5 June 1972 [22 June 1971] 29125/71 Heading B3F [Also in Divisions C7 and F1] A method of casting a metal article, e.g. a turbine blade, comprises introducing a first alloy into a mould, progressively cooling the mould to produce crystal growth in the form of a vertical columnar structure, introducing a second molten alloy compatible with the first into the mould while the surface of the first alloy is in a liquid state and subsequently cooling the mould. A third alloy having the same composition as the first may subsequently be introduced into the mould. The mould 4 is provided with a watercooled base-plate 7 and is surrounded by a furnace 3 which can be raised or lowered relative to the mould. It may be provided with an overflow (30) Fig. 2, (not shown), whose vertical location determines the depth of the first alloy in the mould and hence the position of the interface between the two alloys. The process may be carried out in a vacuum or inert atmosphere the mould being preheated to 150‹ to 200‹ C. above the alloy liquidus temperature.

Abstract: <PICT:0965151/C1/1> <PICT:0965151/C1/2> <PICT:0965151/C1/3> A method for supporting and controlling the temperature of a continuous glass sheet as it emerges from between the upper and lower forming rolls of a glass tank furnace in a pliable state comprises passing the sheet over a supporting tray on a fluid film interposed between the tray and sheet, and directing a fluid medium against the undersurface of the glass sheet in the region between the supporting tray and the lower forming roll to effect a cooling of the glass and to provide support for the sheet to prevent it from being distorted due to its own weight.  Molten glass 11, Fig. 1, passes from a glass melting tank 10 through counter rotating rolls 13 to form a continuous sheet of glass 12 which travels over an air cushion on a tray 16 and thence on to rollers 15. The tray 16 comprises spaced water-cooled tubes 17 and a water cooled duct 18.  Air, preferably moist, is directed upwards between the tubes 17 by conduits 21 which comprise two concentric tubes 53 and 54, Fig. 8, with spacers 55.  Air supplied to the inner tube 54 passes through holes 57 into the outer tube 53 round which it diffuses before being discharged through holes 52. The duct 18, Fig. 5, comprises a water-tight tube within which are mounted a number of pipes 42 in end-to-end relation, the ends being closed by bulkheads 43.  Air passes from the pipes 42 through spaced apertures 45 into an air header 46 and out through perforations 47. The temperature of this air may be controlled by controlling the temperature of the cooling water in the duct 18. The angle and height of the tray 16 is adjustable.  In another embodiment the duct 18 is inclined upwardly with respect to the surface of the tubes 17.  In a further embodiment, Fig. 10 (not shown), a water-cooled duct has an air conduit disposed not within but outside of and below the duct and adjacent the lower forming roll 13.
