Patent GB-814616-A (GB)
Title: Process for the production of phenols
IPC: C07C37/055
Filed: 1956-01-26
Abstract: Phenols are made by treating a diaromatic, a mixed aromatic-aliphatic or aromatic-araliphatic ether, which ethers are of open or cyclic configuration and which contain only one ether oxygen atom connected to any one carbon atom, the ether-oxygen-containing ring of any such cyclic ether containing at least 5 atoms in the ring, with molecular hydrogen in the presence of an alkali-metal and at elevated temperature.  The reaction may be effected in an autoclave with hydrogen under pressure in the presence of excess ether or an inert organic solvent such as a hydrocarbon, for example ligroin or decahydronaphthalene.  An hydrogenation catalyst such as Raney nickel and an alkali-metal transfer agent, i.e. a compound which can readily form organometallic compounds with alkalimetals and can yield the alkali-metal again, such as fluorene, anthracene and cyclopentadiene, may also be present.  Alkali-metals specified are sodium and potassium.  Examples illustrate the preparation of 2-hydroxy-diphenyl from diphenylene oxide and phenol from diphenyl ether, phenetole and anisole.

Abstract: 1,086,616. Polyurethane filaments. AMELIOTEX Inc. Jan. 22, 1965 [Feb. 19, 1964], No. 2876/65. Heading B5B. Wet-spun polyurethane filaments containing longitudinal stresses caused by drawing are heated, while supporting by a belt or on rollers in a dryer, to a temperature above the second order transition temperature and below the melting point of the polyurethane for sufficient time to obtain substantially complete relaxation of said stresses. The draw ratio exerted on the filaments before entering the dryer is suitably 1À1 to 3, and that exerted on the filaments in the dryer preferably does not exceed 1À2. In an example, a solution of polyurethane on D.M.F. is spun into a 20% aqueous solution of D.M.F. at room temperature, and the filaments are passed through a countercurrent extraction system comprising stainless steel trays filled with water, the draw ratio between entry and exit of the system being 1À5. The filaments are then transferred to a dryer (17) (not shown) and heated to 130‹, 160‹ and 190‹ C. successively while supported on belts (19), (20) and (21) respectively. The belts may be made of glass fabric impregnated with polytetrafluorethylene.

Title: Improvements in or relating to apparatus for the mechanical treatment of food
IPC: B02C18/06
Filed: 1945-02-05
Abstract: 591,673. Cutting-machines. SWIFT, Ltd., B. & P., and LATHAM, H. F. Feb. 5, 1945, No. 2893. [Class 5 (i)] [Also in Group VI] A mincer 8-9, e.g. of the type described in Specification 512,805, [Group VI], is mounted in the same framing as a bowl cutter 2-5, each being driven by separate motors or by independent drives to allow continued operation of either machine without the other. Alternatively, a single motor may operate both, with means for interrupting the drive to the bowl cutter 2-5. The mincer 8-9 is driven from the motor 11 through reduction gearing. The bowl 2 is rotated from the shaft 12 of another motor by a belt 14 and worm-gearing 16, 17. The bowl knives 5 are driven by a belt 13. The cover 6 guarding knives 5 can be opened by hand only when a hand lever 19 is turned to dotted position. This operation rotates a drum 21 having a gap 22 which allows a plunger 24 of a switch 26 to break the motor circuit. This drum rotation also slackens a steel band 25 passing over a pulley 26 and so allows a weight 27 to swing a lever 28 to tighten brake band 29, whereby the motor shaft 12 is quickly stopped, thus stopping the bowl machine. When the cover 6 is raised its hinged pin rotates so that a projection 32 thereon clears a plunger 33, whereby a switch 34 makes a second break in the circuit of the motor 12. This prevents the danger of restarting the bowl machine by turning back the hand lever 19 when the cover 6 is raised. The hand lever 19 must be turned back to release the brake 29 so that the knives 5 can be turned by hand during cleaning. The bowl 2 has a free-wheel on its shaft between 17 and 35 to allow the bowl to be rotated by hand during cleaning or to accelerate it by hand during working. The machines are cased in a sheetmetal casing 36 to protect the drives. A hinged table 37 may be raised to horizontal position to hold a receptacle under the mincer. A spring looking pin holds the table in either position. Rubber cushions 41 adjustable by spindle 42 are provided on the feet. Mechanical interruption of the drive may be substituted for the interruption of the electric circuit of the motor. Specification 588,211 also is referred to.

Abstract: 695,584. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 9, 1951 [Feb. 14, 1950], No. 3193/51. Class 39(i) [Also in Groups XIX and XL(c)] The Figure shows a circuit in which a C.R. tube 1 comprises a cathode 2, control electrode 3, beam producing means 4, deflecting electrodes 5, 6 and collecting electrodes 7, 8, 12, 13. The electrode 7 has apertures 7<SP>1</SP> and collecting electrode 8 is connected to the deflection electrode 6 so that the electron beam may occupy any one of a number of stable positions. Negative pulses applied consecutively at point 16 cause the beam to move from a given stable position to the next one in a left-wise direction successively so that after six input pulses the beam will have been moved from its initial position to the extreme left-hand position in which it is incident on the left-hand edge of the left-hand end aperture 7<SP>1</SP> of collecting electrode 7. the secondary emissive electrode 12 and the adjacent further collecting electrode 13 are so biased that normally the potential of electrode 13 is greater than that of electrode 12. The seventh applied pulse at point 16 deflects the beam so that it strikes electrode 12 which emits secondary electrons which pass to electrode 13. Hence electrodes 12 and 13 become charged positively and negatively respectively, the negative pulse at electrode 13 being transmitted via capacitor 14 to deflecting electrode 6 so that the beam is deflected still further to the left. After a short time the potentials of electrodes 12 and 13 become substantially constant and capacitor C at point 16 tends to discharge thus the beam moves to the right until it leaves electrode 12 when electrode 13 rises rapidly in potential. This positive pulse is transmitted via capacitor 14 to electrode 6 to deflect the beam rapidly back to its initial right hand position, the negative pulse produced at electrode 12 is applied via capacitor 17 to the control electrode 3 to cut-off the beam during the fly-back period. The fly-back may be accelerated by connecting electrode 12 via a capacitor to the deflection electrode 5. In a modification the electrode 12 may be coupled to the beam producing means 4 instead of to control electrode 3.
