Title: Separation of cycloalkanone oximes
Inventor: METZGER HORST
Filed: 1962-11-15
Abstract: A cycloalkanone oxime hydrochloride is separated from a reaction mixture formed by the action of nitrosyl chloride, or of nitric oxide and chlorine, on a cycloalkane under the influence of light by removing the reaction mixture from the reaction zone in which the photochemical reaction takes place into an extraction zone in which a photochemical reaction is not taking place, adding to this latter zone phosphoric acid of 70 to 90% strength, sulphuric acid of 80% to 100% strength or oleum with a content of up to 10% of free sulphur trioxide, mixing the concentrated acid with the reaction mixture at a temperature below 70 DEG C., separating the two phases formed, recycling the organic phase in the reaction zone in which the photochemical reaction takes place, and removing the acid solution which contains the extracted cycloalkanone oxime as such or in the form of its salt with the extraction acid used.  The photonitrosation reaction used to produce the reaction mixtures containing the cycloalkanone oxime hydrochlorides may be carried out in an inert solvent at -30 DEG  to +40 DEG C. under a pressure of from 1 to 10 atmospheres using light having an effective wavelength of 300 to 500 millimicrons, and in the presence of added hydrogen chloride. Cycloalkanes which can be used in this process include those having 5 to 12 ring carbon atoms which may contain 1 or 2 alkyl side chains having 1 to 5 carbon atoms, e.g. cyclopentane, cyclohexane, cycloheptane, cyclooctane, cyclodecane, cyclododecane, methyl cyclopentane, methyl cyclohexane and ethyl cyclohexane; the cycloalkane may also contain an attached aromatic ring as in tetrahydronaphthalene or an attached cycloaliphatic ring as in decahydronaphthalene. The extraction may be carried out with both the extraction acid and the reaction mixture as stationary phases, stirring being used to promote diffusion of the oxime hydrochloride into the extraction acid, or one of the components may be arranged as a stationary phase and the other component passed over the surface of the stationary phase or through it.  In the latter procedure when the acid is the stationary phase, part of the acid containing the oxime may be continually removed and replaced by fresh extraction acid.  It is also possible to contact the two components with each other in concurrent or countercurrent manner by stirring and/or distribution over suitable baffle or packing means, plates or other flow interrupters.  The solutions of cycloalkanone oxime or its salt in the extraction acid used may be subjected directly to the Beckmann rearrangement to form an o -amino fatty acid lactam by heating the solution at 100 to 150 DEG C. and then pouring the solution on to an amount of water equivalent to at least the weight of extraction acid. In examples, caprolactam, caprylolactam and laurolactam are prepared by this method.  Specifications 788,436, 789,732, 873,257 and U.S.A. Specifications 2,719,116 and 2,818,310 are referred to.
Patent GB-1040638-A (GB)
Title: Improvements in and relating to paper glazing calender equipment
IPC: D21G1/00
Filed: 1964-10-23
Abstract: A paper glazing calender is provided at each end with a double acting cylinder each of which is operative when a relatively high hydraulic pressure is applied to one side of the cylinders to lift the calender rolls, and when a similar high hydraulic pressure is applied to both sides of the cylinders to apply a relatively small nip pressure force to the rolls by virtue of the fact that the force applied to the pistons on each side thereof does not balance due to the surface area taken up by the piston rod on one side of the piston.  There is an electro-hydraulic arrangement acting on the valves in the fluid conduits to ensure that the cylinders act in synchronism.  To avoid the possibility of a high nip pressure being applied to the rolls if there is a fault in the hydraulic system, a non-return valve is provided in a conduit linking the two sides of the cylinders.

Abstract: 1,086,298. Sensing records. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 25, 1965 [Dec. 17, 1964], No. 45058/65. Heading G4M. A record such as a workman's badge comprises a coded arrangement of low reluctance areas which are sensed by an array of permanent magnets and associated reed switches. The record is manually inserted in grooves in a channel bounded by plates 32, 34 the former carrying the permanent magnets 36 and the latter carrying the reed switches (not shown). The reed switches are normally biased to the closed position by permanent magnets 50 on a plate 48. A detent member 60 prevents insertion of a wrongly oriented record. As a record is inserted, it actuates a hammer, Fig. 4 (not shown) suspended on spring members 64, and when the record has been fully inserted it is locked in position by a pivoted lever engaging a hole in the record. A pair of contacts is closed to indicate correct insertion of the record, and a linkage system is actuated to release arm 58 whereby plate 48 pivots away from the reed switches to remove the biasing magnetic force. All the reed switches then open except those whose associated magnets 36 are not shunted by low reluctance areas in the record. The record is ejected by depressing a reset button, but this is prevented until sufficient time has elapsed for the information to be transmitted to a remote point, either by means of a timing mechanism 102 or by signals from the remote point.

Title: Improvements in or relating to Welding Electrodes and the Manufacture Thereof.
Inventor: SIMON WARNER HOWARD
IPC: B23K35/40
Filed: 1966-10-18
Abstract: 1,156,715. Making welding electrodes; rolling; swaging. W. H. SIMON. 18 Oct., 1966 [22 Oct., 1965], No. 46425/66. Headings B3A, B3H, B3M and B3R. [Also in Division C7] A method of making high purity welding electrodes comprises reducing bar-stock of a material substantially free from contaminants, the reduction being effected in a controlled atmosphere, by rolling or swaging the bar-stock, in the absence of lubricant. The use of superpurity gases for gas-shielded arc welding requires the use of welding electrodes free from contaminants such as oxygen, hydrogen, drawing lubricants and chemical cleaning agents, if the quality of the weld is not to be adversely affected. The invention discloses a method of producing wire having a maximum hydrogen content of 10 p.p.m. and a maximum oxygen content of 25 p.p.m. To prevent the formation of surface defects in which dirt and gas are trapped, the wire is reduced in diameter by swaging or by roller dies. Swaging, Fig. 6.-A wire 10 is passed between swaging dies 52 and 54, which rotate about the wire axis and are moved radially, in the directions of the arrows F, by rollers 60. The wire may be heated by an induction coil 56, and oxidation prevented by gas introduced through an inlet 58. Roller dies.-A wire 14 is passed between roller dies, each supported by two backing rollers. The dies are contained in a glove box 66 which is either evacuated or filled with argon. A seal 78 in a sealing box 76 prevents leakage of air into the box. The finished wire is wound on to a reel 79 and removed through an air-lock 74. The roller dies may be driven at the speed of the work. In a modification, Fig. 12 (not shown), four pairs of roller dies are used, each pair being in a plane at 90 degrees to the preceding pair. The starting material for the wire is an ingot made by melting under vacuum or inert gas.
