Abstract: 336,250. Johnson, J. Y., (I. G. Farbenindustrie Akt..Ges.). June 4, 1929. Right to Patent relinquished. Cellulose esters and ammoniacal copper solutions, processes for making filaments and films from.-A true sulphonic acid prepared from a derivative of an aliphatic or cycloaliphatic hydrocarbon containing at least eight carbon atoms or a salt or other water-soluble derivative of such an acid is incorporated in cellulose or cellulose derivatives or materials containing them during the manufacture and production of artificial masses such as threads and films. The sulphonic acids may be added to the solutions or baths used in the processes of manufacture, which include dissolution of cellulose in copper ammonia solution, xanthation and other esterification or etherification of cellulose, and the final production of the artificial masses for example the dry or wet spinning process. In general it is sufficient to employ between 0.1 and 10 per cent of sulphonic acid by weight of the cellulosic material. The products possess uniformity, softness and improved dyeing properties. In an example, the sodium salt of a true sulphonic acid prepared from " tall oil " is dissolved in viscose and the solution is used for making films. In another example, the true sulphonic acid of palmitic acid or its sodium salt, or of the sodium salt of oleic acid, or of oleic butyl ester is mixed with nitrocellulose and ether-alcohol. The solution is spun in the usual manner. In other examples, acetyl cellulose is dissolved in methylene chloride and alcohol containing a true ammonium sulphonate of ricinoleic acid and the solution is spun in an evaporative medium; the ammonium salt of the amide of the true sulphonic acid of oleic acid or the true sulphonic acid of undecylenic acid, or a salt of a true sulphonic acid derived from a fatty acid ester is added to a spinning solution of cuprammonium cellulose; a solution of acetyl cellulose in acetone containing a high molecular true sulphonic acid such as that of oleic butyl ester, or its sodium salt, is extruded into an aqueous precipitating bath; the sodium salt of a true sulphonic acid, of oleic or undecylenic acid or of a fatty acid ester is incorporated in viscose from which films are made.

Abstract: 1,163,353. Push-pull class B transistor amplifiers. INTERNATIONAL STANDARD ELECTRIC CORP. 14 April, 1967 [16 April, 1966], No. 17272/67. Heading H3T. In an audio frequency amplifier, having an input stage 13, a phase inversion and driver stage which comprises transistors 1 and 2 of different conductivity types and a push-pull output stage comprising transistors 3 and 4 of the same conductivity type operating in class B mode, a negative feedback loop, such as 16, 18, is provided between the output an input stages so as to be operable only on halfcycles of the output signal having one polarity to compensate for the unequal drive voltages applied to the output stage. The A.C. negative feedback network 16, 17 and 18 enables the output transistors 3, 4 to be driven symmetrically since if this network were not provided the transistor 4 would be driven with a half-wave of signal voltage of larger amplitude than that which drives the transistor 3 because of the respective outputs from the driver and inverter transistor 1 and 2. A.C. and D.C. negative feedback is provided from 7 to the input transistors 12, 13 to reduce non-linear distortion. A diode 14 and thermistor 15 stabilize the working points of the transistors 1-4. In a known circuit (Fig. 1, not shown) for symmetrically driving the output stage 3, 4 a resistor (11) is connected between the emitter of the transistor 2 and the output line 7 to reduce the gain of this transistor.

Abstract: 969,274. Delivery sheets. VERKSTADSAKTIEBOLAGET MEKANO. May 5, 1962, No.17371/62. Heading B6H. Newspapers in an overlapping stream having gaps between batches of predetermined number are passed by coiled wire conveyers 16, 11, Fig. 1, on to two prongs 38, Figs. 1 and 2, to form a stack between the end of the conveyer 11 and stops 33, the shape of the prongs 38 compensating for the greater thickness of the folded side of the papers. Rollers 24, 27 having grooves supported on wires of an upper conveyer 18, press on the papers to remove air from the folds. A feeler 45 detects the gaps in the stream and controls an hydraulic cylinder 44, which causes a cross-bar 43 to move ejector rods 42 forwards and move the pile off the prongs 38 on to a further conveyer 39. The return movement of the ejector is initiated when the feeler 45 is depressed by the following sheets and when a further control is actuated by the ejector reaching its right-hand position. As the ejector returns, the papers of the next stack rest on horizontal portions 47 of the rods 47, being swept off to fall on to the prongs 38 as the ejector completes its return movement. As the papers fall into the stack, they are jogged by two vertical spring arms 48, Figs. 2 and 3, vibrated by pins 50 on two of the conveyer pulleys 14.

Title: Improvements in or relating to jet pipe arrangements for jet-propulsion engines
Inventor: BRITT JACK
IPC: B64C9/38
Filed: 1953-06-23
Abstract: 743,874. Jet-propelled aircraft. ROLLS-ROYCE, Ltd. June 15, 1954 [June 23, 1953], No. 17438/53. Class 4. [Also in Group XXVI] A jet pipe arrangement for jet-propulsion engines comprises an upstream portion terminating at its downstream end in a circular opening in a plane oblique to the plane of its inlet, and a downstream portion terminating at its upstream end in a circular opening in a plane oblique to its outlet, the said circular openings registering, and means to rotate the portions about axes normal to their inlets or outlets. The operation is shown in Fig. 2, where the upstream portion 3 is rotatably sealed to the engine exhaust duct 2, and is bevelled at, say, 45 degrees at its outlet, where it engages the downstream portion 4 at its bevelled inlet. The pipes are in practice made elliptical in cross-section so that their bevelled ends may be circular. Rotation of the two portions 3 and 4 will vary the direction of efflux, in particular if they are rotated equally in opposite senses, the direction of efflux lies always in the same vertical plane. A practical embodiment is shown in Fig. 4, where each pipe is circular throughout, but curved. Portion 8 is provided with a gear ring at its outlet and inlet, and portion 9 with one at its inlet. The inlet of portion 8 is kept in register with duct 7 by a flange case 13, and its outlet is kept in register with the inlet of portion 9 by a flange case 18. The gear ring on the inlet of portion 8 is driven by an electric motor 27, and the gear ring 16 at its outlet meshes with a gear 28 driving the gear ring 17 on the inlet of portion 9, the latter thus rotating equally and oppositely to the portion 8. Gear 28 is mounted in a pin 30 projecting inwardly from a ring 21, the latter being mounted at pivots 24 to brackets 23 secured to fixed structure. As portions 8 and 9 rotate, the plane of flange case 18 rotates (about axis 10), and ring 21 slowly rotates on pivots 24. In Fig. 15, the pipe is in three portions 60, 61, 62, each jointed to the adjoining one by the same means as is shown in Fig. 4, but the ring 21 pivoted at 30 to the flange case 18 between portions 61 and 62 is pivotally joined to a U-shaped strap 65 extending between the two pivots 22 illustrated and the two diametrically opposite ones on the other side of the apparatus. With this construction, the efflux may be horizontal, for normal propulsion, vertically downwards, or deflected through 180 degrees for braking.

The plate 18 is provided with a weir 19 over which de-aerated water flows by way of baffles 21 and a central passage 22 to the outlet 12.  If desired, the plate 18 may be crimped, corrugated or/and dented, and may be provided with upstanding baffles 20.  25 denotes a connection for a safety valve for the shell 10.  Steam from the inlet 13 flowing upwardly through the perforations in the plate 18 imparts sensible heat to the water. The heat exchanger 15 is so arranged that a small portion of the steam and vapour rising from the chamber 17 will not be condensed but will flow, together with air and gases, in an uncondensed state through vents 24 to atmosphere so as to prevent the re-absorption of air and gases by steam and vapour being condensed in the heat exchanger 15.  Thus, the amount of air and gases which are returned to water in the chamber 17 is maintained small.  A modified de-aerator with the same principles is also shown in the Provisional Specification.
