Title: Improvements in and relating to the production of oxygen-containing organic compounds
IPC: C07C45/50
Filed: 1949-09-12
Abstract: Oxygen-containing compounds, especially aldehydes, are made from alkene mixtures containing C4 or higher alkenes, especially a -alkenes, containing also di- or poly-enes, which may be alicyclic or aliphatic, by having in a reactor a neutral organic substantially inert medium containing dissolved therein as a soluble compound at least 0.1 per cent. by weight of cobalt calculated as metal, and forming an active carbonylating catalyst by passing at elevated temperature and pressure a mixture comprising CO and H2, in which the partial pressure of CO is at least 50 atmos. and preferably with a molar ratio of at least 1:3, and thereafter feeding, while the prepared mixture is contained in the same or a different reactor, a mixture comprising CO and H2 in which the molar ratio is at least 3:7 together with the liquid alkene feed and continuing to carbonylate the mixture while maintaining the concentration of dissolved cobalt in the carbonylation zones at at least 0.1 per cent. by weight of the liquid.  C4 to C15 especially C4 t C12 and C6-C8 mono-olefines are processed, the last mentioned being obtainable by the thermal cracking of hydrocarbons.  Di- and poly-enes have higher densities and refractive indices than the corresponding mono-olefines and their presence is detected by refractive index and density measurements and infra red spectroscopy.  Specified reaction conditions are 130-190 DEG C., preferably 150-175 DEG C. and 200 to 300 atmos. gauge, preferably 250 atmos.  Specified media are saturated butene trimer, hydrogenated alcohol product, high boiling paraffinic hydrocarbons, e.g. C16 hydrocarbons, and high boiling residues comprising ethers and ether alcohols obtained from the hydrogenated product of carbonylation.  Cobalt is preferably introduced as a soluble carboxylic acid salt dissolved in the liquid medium, e.g. the naphthenate, acetate, laurate, hexahydrobenzoate or 3, 5, 5-trimethyl hexoate.  The product may be hydrogenated to the alcohol using, e.g. a copper or nickel catalyst, especially copper-on-zinc oxide and copper-on-chromia, at about 250 atmos. gauge.  In an example a C6-C8 alkene feed obtained by the thermal cracking of paraffin wax is carbonylated in a saturated C7 to C9 aliphatic mono-alcohol mixture in the presence of 0.1 per cent by weight of cobalt or naphthenate using gas mixtures at 250 atmos. comprising 25 per cent. CO and 75 per cent. H2 and 30 per cent. CO and 70 per cent. H2 in the catalyst forming and carbonylation stages respectively. The products are hydrogenated n-heptanol and 2-methyl hexanol being obtained from n-hexene and the corresponding alcohols from n-heptene and n-octene. Specification 631,316 is referred to.

Title: Apparatus for cutting off lengths from bars of material
IPC: A23G9/28
Filed: 1936-08-27
Abstract: 474,540. Sawing. GAUNT, J. G. (Vogt Processes, Inc.) Aug. 27, 1936, No. 23566. [Class 145 (ii)] [Also in Group V] A device for cutting-off lengths of continually advancing material such as a bar of wrapped ice-cream comprises a double-edged blade movable transversely through the material while travelling therewith, and means for causing the opposite edges of the blade to cut the material alternately. As shown, a bar 11, Fig. 3, of wrapped ice cream is fed through tubular guides by grooved rollers 28 to a tubular guide 79 that is secured to a slide carrying a two-edged saw 119 and is reciprocated by rack-and-pinion mechanism 96, 97 to move at the same speed as that of the material during its forward movement. The saw 119 is adapted to be oscillated about a shaft 128 to move, transversely through the material by an intermittently-rotated cam mounted on a shaft 105 and engaging a roller 120, Fig. 12, on a forked member 125 slidable on a rod 123. The fork engages a pin 126 on an extension 127 of a sleeve 153 rotatable about the shaft 128. The saw is mounted on a slide 136 that is vibrated by an eccentric 133 on the rotating shaft 128. In use, the saw, on one forward movement, cuts through the material as it is oscillated in one direction about the shaft 128. The cutter supporting means including the guide are then moved to the left, and on the next forward movement, the saw is swung about the shaft 128 in the opposite direction so that its other edge effects the cutting. In order to support the forward end of the bar 11 during the cutting operation, curved guide members 170, 171, Fig. 13, are carried by parallel link devices 184 from members slidable on shafts 174. During the forward movement, the members 170, 171 occupy the position shown in dotted lines. After the cutting operation, they are moved apart and allow the severed length to fall on to a conveyer in a refrigerating chamber. Specifications 332,577, [Class 86], 345,850, [Group XIII], 424,858, [Group XVII], and 474,541, [Group XIII], are referred to.

Patent GB-813857-A (GB)
Title: Production of antificial filaments of uneven denier
IPC: D01D5/20
Filed: 1956-08-01
Abstract: Artificial filamentary materials having a variation in denier along their length are produced by drawing the materials under tension to reduce their thickness and periodically varying the length of path of the materials, to vary the drawing ratio, by running them, while they are being drawn, over a guide surface which deflects them from a direct path in a plane containing said direct path, and moving the surface transversely to the plane.  The guide surface may be the peripheral rim of a cam mounted for rotation in a plane transverse to the path of the filaments, the axis of rotation being substantially parallel to said path and the radius of the cam increasing gradually and uniformly and then decreasing abruptly so as to cause a corresponding abrupt decrease in the rate of drawdown. Alternatively the cam, e.g. in the form of a flat bar, may be mounted for rotation in a plane parallel to the path of the filaments, provision being made for periodically moving the cam as a whole transversely to the path so that the desired abrupt reduction in draw-down is caused by the filaments slipping off the side edge of the cam as the cam moves transversely.  The guide surface need not have any rotary motion and may, for example, be a rod, mounted transversely to and below the path of the filaments, which may be moved upwards to engage and lift the filaments to lengthen the path of the filaments, then transversely to the path of the filaments until the filaments slip off the end of the rod, and then downwards under the filaments to start the cycle anew. Although the process is particularly applicable to the spinning of artificial filaments it may be used to produce filaments of uneven denier by stretching previously spun filaments, means being provided for bringing the filaments to a plastic condition.  The process may also be used for the cold drawing of nylon filaments to give filaments of uneven denier.

Abstract: 915,565. Centrifugal separators. WESTFALIA SEPARATOR A.G. July 13, 1960 [Sept. 24, 1959], No. 24410/60. Class 23. [Also in Group XXIX] The formation of foam on the liquid in the outlet chamber 1 of a bowl 2 is prevented by keeping constant the distance h; a stationary skimmer 8 extends into the liquid. The rotation of the liquid is maintained by vanes 5, 6. Variation in the position of the liquid surface causes pressure variation in a duct 10, 11, 12, and this pressure variation operates the valve shown in Fig. 2 which is connected at an inlet 15 to the outlet channel 7 in the skimmer. The duct is connected to a valve chamber 13 so that the pressure variations move a piston 24 to result in the movement of a piston 18 in a valve chamber 17 to alter the cross-section of an annulus 16 between the inlet 15 and the valve outlet (not shown). The liquid pressure in the duct may be used to operate a pneumatically controlled valve.

Abstract: 1314946 Digital transmission systems; frequency modulation ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI 19 April 1971 [18 March 1970] 24534/71 Heading H4P To provide smooth transition between frequencies f0 and f1 in an FSK system, a generator 1 of frequency f0 supplies carrier signals through a phase shifting circuit 2 to which are added signals of frequency #f, where #f=f1-f0, produced by a generator 6 through a second phase shifting circuit 5. In the embodiment described the outputs of each phase shifting circuit have a difference of 90 degrees which outputs are multiplied in transistors 3, 4 and applied to a summating circuit 9 hence providing signals of f0, f1 to an inverter having transistors 10, 11 controlled at frequency #f, or a sub multiple, in accordance with a binary message M and its complementary value M<SP>1</SP>. Changing from one frequency to the other takes place at passages through zero of the signal hence without phase modulation. Signals R determine the rate of succession of the transition instants. If the rate of succession is made equal to one half of the inverse of the frequency #f there will be obtained a phase reversal which could be utilized to effect transmission by 180 degrees phase modulation but in this case it will be necessary to provide a discriminator which assigns an inverse phase to a detected phase in every alternate instance.
