Filed: 1975-01-03
Abstract: 1483126 Electrolysis of cyanide wastes and cell therefor ELECTRICITY COUNCIL 2 April 1976 [3 Jan 1975] 267/75 Addition to 1423369 Heading C7B  Dilute metal cyanide solutions e.g. electroplating rinse, are electrolyzed in a cell containing a bed of non-conducting particles fluidized by upward passage of the solution, the bed being in contact with an anode and cathode both having apertures or surface irregularities and having a relative effective cathode: anode area of 1À3 to 2:1. Metal, e.g. Cu, Zn, Ag is cathodically recovered, while cyanide is anodically oxidized. Electrodes of Pt or PbO 2  on Ti, or of graphite are useful; the cathode may be Cu. Mesh, perforated or rod-like electrodes are useful, with holes large enough to pass the particles which may be of sand, glass or plastics. A porous cell base-plate may admit electrolyte which is recirculated via a rinse tank for articles from an electro-plating operation.

Abstract: 1357824 Removing Brussels sprouts from their stalks J A VAN DONKELAAR 5 Jan 1972 [12 Jan 1971] 401/72 Heading A4C A device for stripping Brussels sprouts from their stalks comprizes a plurality of cutting members 1 each in the form of a bell-crank lever and provided with a knife 6 fastened on one end of an arm 8 of the lever and the other arm 10 of the lever lying circumferential to a rotatable supporting member 2. The arm 8 is connected to an auxiliary member 5 via a pivotal joint 4, and is coaxial with the supporting member 2, said lever being pivotally connected to the supporting member at a point 3. Means (12) Fig. 3, (not shown) are provided to alter the relative angular position of members 2, 5 and so allow stalks of various diameters to be introduced into the device. A small relative rotation of the members 2, 5 which are both supported in a bearing (15) and rotatable together owing to a common drive mechanism comprizing a rope engaging a V-shaped groove (14) in member 2, causes the necessary tilting of the levers. The stalk of each plant may be manually or mechanically passed into the device, and in the latter instance a pair of rollers (16) may be utilized. As a result of the centrifugal force caused by the rotating members 2, 5 the knives 6 are pressed against the stalks and facilitate stripping of the sprouts without biting into the stalks.

Title: Improvements in and relating to the production of ketenes
Inventor: HENDERSON GEORGE MANN
IPC: C07C45/88
Filed: 1951-01-08
Abstract: A process for the production of ketenes by the thermal decomposition of aliphatic ketones in a heated reaction vessel constructed of a heat-resistant alloy steel containing both chromium and nickel is characterized in that trithioacetaldehyde is incorporated in the ketone prior to its thermal decomposition so that the deposit of carbon on the walls of the reaction vessel is maintained at a negligible amount during the thermal decomposition.  In an example, acetone is passed over molten trithioacetaldehyde and then through a heated reaction tube of stainless steel containing chromium, nickel and titanium, heated by the passage of electric current through the metal to obtain ketene.  Specification 629,211 is referred to.

Title: Suppression device for polarized light hole burning using acousto-optical modulator
Inventor: FRASCOLLA MASSIMO
IPC: H04B10/135
Filed: 1999-01-04
Abstract: PROBLEM TO BE SOLVED: To reduce polarized light hole burning in a rare-earth doped fiber amplifier in an optical communication system. SOLUTION: Polarized light hole burning is reduced by covering an optical carrier signal with a characteristic wavelength into a polarized light rotation carrier. Orthogonal rotation is caused on a polarized light of a part of an optical carrier by the use of an acousto-optical modulator 320, that modulates the part of the optical carrier. A polarized beam combiner 335 combines the modulated orthogonal signal from the acousto-optical modulator 230 with the rest of the original optical carrier, to produce the polarized light rotation optical carrier. The polarized light rotation optical carrier is inserted in an optical communication system 300, and consequently is used in the inside of a rare-earth doped fiber amplifier 340.
