Title: Improvements in or relating to the purification of acrylonitrile
Inventor: GRICE ROY
Filed: 1962-07-06
Abstract: Mixtures of acetonitrile and acrylonitrile, especially such mixtures produced by the vapour phase reaction at elevated temperature of propylene, ammonia and molecular oxygen, are separated by extractive distillation in the presence of ethylene glycol, diethylene glycol, propylene glycol or glycerol, preferably in admixture with water, especially from 20-80% by weight thereof. The process may be carried out by feeding the mixtures of nitriles and that comprising the glycol together or at separate points to a distillation column, withdrawing purified acrylonitrile containing water overhead and acetonitrile glycol as base product. Acetonitrile and glycol can be separated by distillation and the glycol recovered may be recirculated. The examples describe the use of aqueous ethylene glycol.

Abstract: 713,931. Television. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Oct. 16, 1952 [Oct. 25, 1951], No. 26015/52. Class 40 (3) The black level at the output of a television transmitter is maintained constant by means of a negative feedback path between an output circuit of the transmitter and a preceding video stage The feedback path comprises the series combination of a detector, low-pass filter, first electronic switch, integrator and record electronic switch the pass-band of the L.P. filter being sufficiently inside to transmit video and synchronizing signals and the time-constant of the inegrator circuit being such that self-oscillation is prevented. In Fig. 3, which shows the general arrangement the detector comprises a double-diode D connected, via transformer L, to an output circuit of the transmitter and, via the L.P. filter L1, C2, to a clipper stage E which clips the input signal at point C (curve C, Fig. 4) on both sides of the black level to produce a signal of about 20 per cent of the input signal amplitude. The clipped output (curve D, Fig. 4) is then fed, via a cathodefollower stage V, to a first electronic switch Cr, (which is "opened" by pulses synchronized with the synchronizing signals and fed thereto via condensers C3, C4) the output circuit of which (terminal f) is connected to a condenser C7 which with the internal resistance of the diodes of switch Cr, forms an integrating circuit with a timeconstant such that variations of black level occurring at line frequency (10 to 20 Kc/s) are faithfully transmitted whilst signals of higher frequency (e.g. above 100 Kc/s approx.), are not transmitted. The signal developed across condenser C7 (curve F, Fig. 4) is then supplied via a second electronic switch Ce (controlled in the same manner as switch Cr) to the grid of a video stage (valve T) which may be the first stage of a D.C. coupled amplifier immediately preceding the modulated H.F. stages of the transmitter.

Title: Improved gas turbine engine
Inventor: WARD PETER ARTHUR
IPC: B64C29/00
Filed: 1958-08-15
Abstract: 883,634. Vertical take-off aircraft. ROLLSROYCE Ltd. July 31, 1959 [Aug. 15, 1958], No. 26385/58. Class 4. [Also in Group XXVI]. In an aircraft gas turbine engine adapted to produce vertical thrust for vertical flight, hovering or vertical take-off, the compressor air intake comprises internal wall members disposed downstream of the nose of the engine and spaced apart, or adapted to be spaced apart, to provide between them an annular gap, the internal wall members being shaped to direct air through the annular gap and into the air intake. In the engine shown, vertical thrust is obtained by tilting the engine through 45 degrees from the horizontal position into the position shown, a movable jet nozzle part 32 being tilted through 45 degrees relative to the engine so that it assumes the vertical position shown. The nozzle part 32 and an intermediate nozzle part 31 are interconnected by gearing in the manner described in Specification 883,633 (see Group XXXIII) so that nozzle part 31 moves, relative to the engine, through half the angle moved through by the part 32. At the same time, a centre body 1 and nose portion 2 are moved axially forward to open a gap 11 between the nose portion 2 and the remainder of the engine nacelle. The gap 11, which is generally annular but oblique to the axis of the engine, provides an intake with ram effect due to the forward flight of the aircraft. In a modification, the jet nozzle is fixed and the engine is tilted into a vertical position. The annular gap may be formed in the engine casing itself if there is no nacelle, and the means for closing the annular gap may comprise a sliding cylindrical valve coaxial with the engine.

Title: Co-ordinate converters
IPC: G06G7/22
Filed: 1950-10-30
Abstract: 681,511. Electric analogue calculating systems. BRITISH THOMSON-HOUSTON CO., Ltd., and THOMAS, D. C. Oct. 30, 1950, No. 26399/50. Class 37. [Also in Group XL (b)] An apparatus for converting the co-ordinates of a point relative to a first system of reference, e.g. polar or cartesian, into co-ordinates relative to a second, cartesian, system of reference comprises a cathode-ray tube having a primary deflecting means for deflecting its spot to a position defined by the first co-ordinates, photoelectric means arranged to be excited in response to a displacement of the spot from the origin of the second reference system and secondary deflecting means operated by the response E.M.F.'s being proportional to the required co-ordinates. As shown in Fig. 1 the cathode-ray tube 1 comprises primary and secondary deflecting means 2 and 9 having displaced origins 3 and 6 on the screen 4, the axes of the second, cartesian, co-ordinate system being indicated at 5. Four photo-electric cells 7 coupled via amplifiers (not shown) to the deflecting means 9 are excited by light from the screen 4 and masks 8 mounted perpendicular to the screen allow each cell to be excited only by light from a single quadrant of the screen, each quadrant being symmetrical about an axis 5 and the masks being so arranged that when the spot is at the origin 6 none of the cells are illuminated, so that the spot is maintained substantially at the origin 6. When voltages proportional to the first set of coordinates are applied to deflecting means 2 the spot tends to be displaced from the origin 6 but any such displacement causes excitation of one or more of the cells 7 tending to restore the spot to the origin 6, the restoring voltages applied to deflecting means 9 being proportional to the co-ordinates referred to axes 5. In a modification, Fig. 2, employing two photo-electric cells, a single mask 11 perpendicular to the tube screen is aligned with the horizontal axis 5 and the left-hand half of the screen is covered by a red filter 10, a blue-sensitive photo-electric cell 12 coupled to the X deflectors 9 being positioned to receive light equally from both sides of the mask 11 and an all-coloursensitive cell 13 coupled to the Y deflectors 9 being positioned in the top right quadrant of the screen. The primary deflecting means 2 may comprise a single rotatable coil or two crossed coils, depending on whether the first reference system is polar or cartesian.
