Title: Improvements in purification of nickel electrolytes
IPC: C25C1/08
Filed: 1940-07-11
Abstract: 542,042. Purifying nickel electrolytes. FALCONBRIDGE NICKEL MINES, Ltd. July 11, 1940, No. 11564. Convention date, Sept. 29, 1939. [Class 1 (iii)] [Also in Group XXXVI] In order to obtain highly purified nickel by the electrolytic process, the nickel electrolyte, such as nickel sulphate, from the electrolytic cells, after being treated in cementation tanks, filtered, and treated with air to deposit most of the iron present as ferric hydroxide, is subjected to the purifying action of freshly precipitated ferric hydroxide while still wet from its precipitation whereby a substantial amount of the remaining impurities are adsorbed thereon. Nickel obtained from electrolysis of the solution may contain only .001 per cent. of arsenic and antimony and .002 per cent. of copper and iron as compared with .004, .0025, .003. and .002 per cent. respectively in the case of electrolyte not treated with the ferric hydroxide. The partly spent ferric hydroxide from the filter press is suspended in nickel electrolyte from the cementation tank and returned to the air treatment stage. In place of ferric hydroxide, the hydroxides of nickel, cobalt, or manganese may be employed. The preliminary purification of the electrolyte may be carried out with finely divided highly reaction nickel. as described for example in U.S.A. Specification 1,986,967.

Title: Oral compositions for hardening dental enamel
IPC: A61Q11/00
Filed: 1965-03-18
Abstract: A dental composition, for rehardening softened dental enamel, consists of a confectionery material or a chewing gum base material with 2.5-12.5% by weight of dicalcium phosphate dihydrate which contains 1-2% by weight of tetrasodium pyrophosphate.  When the carrier is a chewing gum, the dicalcium phosphate ingredient is incorporated by the method claimed in Specification 934,596 or in Specification 963,518.  The confectionery material may be any such substance which provides prolonged exposure, as compared with brushing with a dentifrice, of the teeth to the active ingredient, e.g. breadstuff, cakes, cake icing, candies or lozenges, and cereals, particularly sugar-coated cereals.
Patent GB-1341737-A (GB)
Title: Pattern processing systems
IPC: G06V10/10
Filed: 1971-04-27
Abstract: 1341737 Pattern recognition systems KOGYO GIJUTSUIN 27 April 1971 [28 April 1970 16 Dec 1970] 11627/71 Heading G4R In a pattern recognition system a value K representing the amount of a regular and unwanted component in an input pattern is derived from a set of values f rs  representing sampled portions of the pattern. The value K is subtracted from each of the values f rs  to provide a set of values g rs , representing an output pattern, to recognition equipment. The value K may represent spurious information resulting from the texture pattern of a typewriter ribbon. The system includes circuitry for blurring the input or output patterns. In one embodiment, Fig. 3 (not shown), the input pattern values f rs (f 11 -f MN ) pass to an operational amplifier (A) via weighting resistors (R 11 -R MN ) whose output -K is fed to each of a number of operational amplifiers (B), each fed with a respective one of the values f rs  and delivering one of the output pattern values g rs  (g 11 -g MN ). The input pattern values are obtained from the output of a blurring circuit, or alternatively the output pattern values are fed to a blurring circuit. In a second embodiment, Fig. 4 (not shown), the input values f rs  are fed to first operational amplifiers (B) whose output values g rs  are fed via weighting resistors to an integrating amplifier (A). The output of this amplifier is inverted by an operational amplifier (A<SP>1</SP>), providing the value K to each of the first amplifiers (B). As in the preceding embodiment a blurring circuit precedes the input or follows the output. In another embodiment, Figs. 7 and 8 (not shown), the operations of blurring and removal of the unwanted component are performed simultaneously. The blurring is performed by suitably weighting the values to be blurred, the weighted values being summed in an operational amplifier, Fig. 1 (not shown).

Abstract: 170,872. Tone, F. April 29, 1920. Paper pipes and tubes. - Pieces of paper cut with a straight edge and an oblique edge are coiled into mouthpieces for cigarettes by the apparatus shown. Within a tube E49 a second tube E44 slides and a spindle E41<1> rotates. The spindle E41' carries a pair of gripping blades, one of which is pivoted and is opened by a spring when a slot in the tube E44 is in position to allow the tail of the blade to pass through it. The cut piece of paper is presented to the blades thus opened through a slot in the tube E49 and is then scored by the blades when the tube E44 is retracted. The spindle E44' then rotates, coiling the piece of paper into a tube inside the tube E49. The tube E44 then advances, allowing the blades to release the paper and pushing it into position on the cigarette.

Patent GB-799191-A (GB)
Title: Improvements in or relating to the extractive fractionation of hydrocarbon oils by formation of urea adducts
Inventor: ORDELT HERMANN
IPC: F02B3/06
Filed: 1956-04-20
Abstract: Hydrocarbon oils containing, in part, hydrocarbons which form urea adducts, are extractively fractionated in a continuous process by reaction with urea suspended in a diluent, which is not a solvent for urea, in the absence of urea solution; the urea adducts formed are separated and thermally decomposed at a temperature below the melting point of urea, and recovered urea is recycled.  Diluents referred to are paraffinic hydrocarbons having 3-6 carbon atoms, e.g. butane, and benzene, toluene, cyclohexane and chlorinated hydrocarbons.  A small proportion, e.g. 10-20 per cent based on the urea, of an activator for urea adduction may be present, e.g. methanol, ethanol, propanol, ethyl hexanol, octanol, furfurol, cresol, acetone, butanone, amyl acetate, diethyl ether, aliphatic aldehydes, sulphur dioxide, alkanolamines, nitriles, boron trifluoride, hydrofluoric acid and ammonia.  The adduct may be separated by filtration and washed, e.g. with the diluent or a solution of the activator in the diluent; the filtrate may be distilled to recover raffinate, and diluent and activator which are recycled.  The adduct may be decomposed by heating to 80-120 DEG  C.  The urea adduction may be effected by passing urea in the diluent in countercurrent with the oil or oil and diluent, e.g. by means of an Archimedean screw in a pipe or trough. The decomposition of the adduct may be similarly effected by passing adduct in countercurrent with the diluent, which may be obtained from a recycle stream of diluent and activator, by distillation or absorption of the activator on activated charcoal.  After a number of cycles the activity of the urea may be restored by melting and resolidifying, e.g. by heating a suspension of urea in diluent to form an emulsion and then contacting the emulsion with cold diluent, the decomposition of the urea adducts or the complete cycle may be carried out at a pressure of not more than 50 atm. in the decomposition zone and 3-5 atm. in the adductforming zone.  Petroleum distillates, e.g. kerosene, diesel oil and gas oil, white spirit, spindle oil, neutral oil and medium and heavy lubricating oils may be treated by the process.  The process may be used for dewaxing wax-containing oils.  Specification 743,177 is referred to.
