Patent GB-738899-A (GB)
Title: New or improved device for sorting and counting coins
IPC: G07D3/04
Filed: 1952-12-17
Abstract: 738,899. Coin sorting and counting. AUTELCA AKT.-GES. Dec. 17, 1952 [Dec. 18, 1951; Nov. 18, 1952], No. 31927/52. Class 27. A device for counting and sorting coins has a rotating worm 4, cylinder 3 and spring stirrer 11 for feeding coins from a hopper 1 to a rotary plate 5 from which a rotary toothed disc 18 of elastic material delivers coins one at a time to a rail 22 extending through an inclined coin tester having a number of test sections corresponding to the number of denominations of coins to be sorted and the sorted coins are discharged into containers 42 after operating counters which include means for stopping the device' when any one container holds a predetermined number of. coins. A stepped gauge plate 31 extends above the rail 22 and provides an aperture 30 which increases by steps towards the end of the tester; also, in each test section, the aperture is at first slightly smaller than the diameter of coins of the denomination corresponding to that section but allows coins too small in diameter for that denomination to tilt against rails 28 and slide down them for ejection through windows 29 into a reject shoot 27a while correct-sized coins tilt through the correct-sized aperture and slide down the rails into a shoot 26 leading to a counter. Coins that are too thin fall through the clearance c between the rail 22 and a rail 28b into a reject shoot 27b and coins, corresponding to the first two sections, that are too thick will not pass through the clearance b between the rail 22 and gauge plates 24 and 25 and pass in the tilted position through slots 33 until they are rejected because of too-small diameter in a later section. The sorted coins of each denomination fall through a funnel 39 on to a rotating plate 38 in each counting device and are driven round by a rubber ring 40 so that they operate a spring- loaded lever 41 connected to another lever that operates a contact in the electrical circuit of the counter and are then discharged into a container 42. Each impulse caused by the lever 41 is recorded by a unit counter connected to a totalizer and, after one hundred coins have been counted, relays switch off the driving motor, illuminate a warning light corresponding to the filled container, sound an acoustic signalling device and move a dog to prevent 'movement of the lever 41. The device is reset for continued operation by replacing the filled container with an empty one, thus operating a contact in the member holding the containers and resetting the relays.
Patent GB-904302-A (GB)
Title: Improvements in processes for the production of caprolactam
Filed: 1959-09-18
Abstract: Caprolactam is prepared by reacting hexahydrobenzoic acid, or a functional derivative thereof, in the presence of free sulphuric acid having a concentration of at least 85% by weight, with a nitrosylation agent capable of providing NO+ ions in the reaction medium; free SO3 may also be present.  Specified derivatives of hexa benzoic acid are the salts, esters, anhydride, chloride, nitrile and amide.  Suitable nitrosylation agents are NO, N2O3, alkyl nitrites, salts of nitrons acid, nitrosyl sulphuric acid, nitrosyl sulphuric anhydride and nitrosyl chloride or bromide.  Preferably, the nitrosylation agent is used in less than molar proportions relative to the hexa hydrobenzoic acid material and at least 2.5 mols of H2SO4 are used per mole of nitrosylation agent. Reaction temperatures may range from 30 DEG -200 DEG C. but lower temperatures may be used when SO3 is present.  In the reaction the group attached to the tertiary carbon of the cyclo hexyl ring is split out.  The free acid, salts and esters thereof yield CO2 as by-product.  The reactants may be brought together in any order, if desired in continuous manner.  One preferred method comprises mixing the reactants at not substantially above 50 DEG C. maintaining the mixture at a temperature at which there is no substantial evolution of CO2 until part of the NO+ ions are used up and then heating to at least 60-70 DEG C. In another method, the nitrosylation agent and H2SO4 or oleum are added to the hexa hydro benzoic acid or its derivative at an elevated temperature at which substantial evolution of CO2 occurs.  In addition, a mixture of all the reactants may be fed into a heated reacted mixture of nitrosylation agent and hexa hydro benzoic acid or derivative thereof.  Numerous examples are given illustrating these procedures using hexa hydro benzoic acid, its sodium or potassium salt or methyl ester and N2O3, nitrosyl sulphuric acid, nitrosyl chloride or ethyl nitrite.  In some cases, the temperature is controlled by carrying out the reaction in a low boiling inert liquid under reflux, e.g. cyclohexane.  The crude product is worked up by alkaline washing and solvent extraction to recover the lactam.

The invention comprises compounds of the formulµ and acid addition salts thereof. The compound of the Formula I is prepared by ethylating a-pyrrolaldehyde, condensing the thus produced N-ethylpyrrolaldehyde with benzyl cyanide in alkaline medium to give alpha-(N-ethylpyrrol-2- ylmethylene) benzyl cyanide which is hydrogenated in the presence of palladium to a-(N- ethylpyrrol-2-yLmethyl) benzyl cyanide, which is hydrolysed to the corresponding carboxylic acid. The thus produced acid is converted into its amide which is hydrogenated to give alpha-phenyl-#- (2-N-ethylpyrrolidyl) propionamide which is dehydrated to the corresponding nitrile and cyclohexylated. The compound of the Formula II is prepared by converting a-phenyl-a- (3-pyridyl) acetamide into its ethobromide with ethyl bromide in dimethyl sulphoxide, hydrogenating the ethobromide, dehydrating the resulting alpha-phenyl-alpha-(3-piperidyl) acetamide and cyclohexylating the thus produced a-phenyl-a- (3-piperidyl) acetonitrile. Mixtures of the compounds of the Formulµ I and II are prepared by reacting 1-ethyl-3-chloropiperidine with an alkali metal derivative of phenylcyclohexylacetonitrile.

Title: Improvements in the production of pictures by the dye-transfer process
IPC: G03C7/25
Filed: 1925-12-24
Abstract: 245,163. Arx, R. von. Dec. 24, 1924, [Convention date]. Colour photography; photo-mechanical printing- surfaces.-A process of producing, by dye transfer, monochrome or multi-colour prints having identical colour values consists in treating a silver positive, or each of a set of colour-record silver positives, with a substance or substances so as to convert the silver of the image into a mordant, dyeing the image with a dye having an affinity for this mordant, and transferring the dye picture by placing the positive, in moist contact, with or without pressure, with a copy sheet which in itself, or by virtue of a mordant contained therein, has a greater affinity for the dye than the mordant in the positive, so that a complete transfer of the colour results. The sheet may be of collodion or other nitro-cellulose derivative, or of gelatin containing a mordant. In the case of two-colour or three-colour pictures the colourrecord positives may be originals or reproductions from a multicolour screen-plate negative. The mordant in the copy sheet may be removed therefrom after the picture has been transferred to it. The positives may be dyed repeatedly to make repeat pictures. An example is described in which a silver positive image is converted in a toning bath containing copper sulphate, neutral ammonium citrate, potassium ferricyanide, and ammonium carbonate, into a mordant comprising the ferrocyanides of silver and copper. The mordant image is washed and immersed for 10 minutes in a dye-stuff such as methylene blue. The dye picture is transferred by contact in moist condition, either to a plain collodion sheet, or to a sheet of paper coated with gelatin containing cuprous thiocyanate as mordant, which may remain in the copy or be removed.
