Title: Improvements in or relating to labelling devices
Inventor: NIGRELLI BIAGIO J
IPC: B65C1/02
Filed: 1954-08-12
Abstract: 765,918. Labelling devices. NEKOOSAEDWARDS PAPER CO. Aug. 12, 1954, No. 23487/54. Class 73. In a labelling device, a succession of packages move along a table 12, Figs. 3, 4, provided with a back-up bar 13 and a hopper 16 for a pack of labels extends with its open side along one side of the table and is mounted for relative sliding movement on a carriage 15, Fig. 5, which is moved towards and away from the table by a fluid pressure cylinder. The hopper 16 is moved relative to the carriage 15 by the operation of a pressure bar 17 fixed to the carriage 15 and providing a backing for the pack of labels for applying pressure thereon and to bring the end label into contact with a package on the table 12. The force applied to the pressure bar 17 on movement of the carriage 15 is applied eccentrically of the centre of the hopper 16 whereby the bar 17 first brings the leading end of the end label in contact with the package and then brings the label into full engagement with the package with a rolling action. The hopper is retractibly biased with respect to the bar 17 by a leaf spring 18. Spring urged moistener and pressure rolls 19, 21 mounted on a fixed plate 23 serve respectively to moisten the side of the package and to press thereon the applied label. The carriage 15, also mounted on the plate 23, is movable in a central slot 36 in the plate 23 and a slot 57 in the bottom 54 of the hopper 16 receives a lug 59 of the carriage 15 to permit relative movement of the carriage 15 and hopper 16. The carriage 15 moves in and is supported by spaced guides 66 secured to the plate 23 and in alignment with opposite sides of the slot 57 whilst a flanged collar 76 on the carriage 15 is slidably guided along the slot 57. The collar 76 is secured to a boss 60 provided with supporting arms 63 for the hopper 16 and being rotatably mounted on a shaft 61 on which the lower slide part 65 of the carriage 15 is threaded. Thus, as seen in Fig. 5, the hopper 16 is supported eccentrically of the centre and on movement of the carriage 15 and hopper 16 towards a package, the pressure bar 17 pivots the hopper 16 in a clockwise direction, as seen in Fig. 3, to engage the leading end of the label with the end of the package and then presses the label on to the package from leading to trailing end with a rolling action. The pressure bar 17 is adjustably mounted on the lug 59 of the carrier 15. Clips 95, 96 mounted on the hopper 16 releasably engage the edges of the advance label in the pack, the clip 95 being mounted on an end plate 98 which is adjustable, together with the length of the pressure bar 17, in accordance with the length of the labels. Specification 765,919 [Group XVI] is referred to.

Title: Improvements in or relating to surface discharge sparking plugs or other igniters
Inventor: SAYERS FRANK MANNINGTON
IPC: H01T13/52
Filed: 1952-10-31
Abstract: 745,016. Ceramic-metal seals. LODGE PLUGS, Ltd. Oct. 31, 1952, No. 23508/53. Divded out of 26027/51. Class 36. [Also in Group XXVII] A surface discharge sparking plug or other igniter includes a pair of electrodes of a metal having a higher sintering or fusion temperature than that of copper oxide, an electric insulator separating said electrodes, and a continuous semi-conducting spark discharge path of copper oxide extending between said electrodes and intimately uniting the insulator therewith. In one arrangement, Fig. 1, the central electrode 11 is separated from the earthed electrode 12 by an insulator 10 which may be of ceramic material such as alumina, and the spark discharge path is formed by a layer 13 of copper oxide the active face of which is flush with the ends of the electrodes. In a modified arrangement, Fig. 2, the copper oxide layer 13 is formed on an insulating pellet 15 abutting the main insulator and a nickel-iron earthed electrode 14 is separate from but lies in contact with the plug body 16. The air gaps between the electrodes and insulator and the exposed surface of the latter are filled or coated with copper oxide which is fused or sintered at a temperature below the fusion or sintering temperature of the electrodes or ceramic insulating material. The copper oxide may be in either the cuprous or cupric form or may be a mixture of these, and may be applied by painting or spraying and adhesion and compacting obtained by heating above or preferably just below the oxide melting point of 1250‹ C. Control of the conducting properties of the oxide layer may be effected by adjustment of the sintering temperature and furnace atmosphere. Heating for five minutes at 1100‹ C. in an oxidizing atmosphere produces satisfactory results. The electrodes may be assembled on to the ceramic base after the copper oxide layer has been applied and fired, but it is preferred to assemble the electrodes on to the ceramic base before firing the copper oxide layer. The electrodes may be coated with copper before the firing operation to ensure more intimate contact.

Abstract: 407,615. Cooking-stoves; burners. SVENSKA AKTIEBOLAGET GASACCUMULATOR, Liding÷, near Stockholm. Aug. 25, 1933, No. 23653. Convention date, Nov. 3, 1932. [Classes 75 (i) and 126.] In combustion apparatus comprising a burner supplied with vaporized fuel from a vaporizer heated by conduction from the burner, and in which the combustion gases pass through piping to the points at which the heat in them is utilized, the burner is heat-insulated or in bad heat-conducting connection with these points ; variations in temperature at these points do not therefore substantially affect the temperature of the burner, which therefore supplies heat to the vaporizer at a substantially constant rate and so maintains it at substantially constant temperature. In the heat-accumulating cooking-stove shown, oil from a pipe 19 and air from a pipe 23 are supplied to a vaporizer 18 integral with a hollow annular member 17 forming the base of the burner, and on which are supported perforated burner tubes 28, 29. The vaporized oil passes up the annular space between the tubes, and combustion occurs in this space with the aid of air supplied through channels 12, 13 and passing through the perforations of the tubes 28, 29. The outer wall 32 of the annular base member 17 is higher than the inner wall 31 and is heated by the combustion occurring at the lowermost orifices of the central tube, the parts being so proportioned that heat is conducted at the required rate to the vaporizer 18. The hot gases pass from the top of the burner to a chamber 15 to heat the hot-plates 2, 3 by way of a pipe 14, which, as well as the burner tubes 28, 29 is made of material of low heat-conductivity, such as chromium-iron alloy, in order that temperature variations at the hot-plates &c. shall not affect the temperature of the vaporizer. For the same purpose, slots 33 may be made in the burner pipe which serve also as flame orifices and may replace the perforations.

Patent GB-765590-A (GB)
Title: Improvements in and relating to derivatives of purine
IPC: C07D487/04
Filed: 1954-08-23
Abstract: The invention comprises 6-mercapto-8-azapurine, bis - (8 - azapurinyl - 6 -) - disulphide, 2-amino - 6 - mercapto - 8 - azapurine and bis-(2 - amino - 8 - azapurinyl - 6 -) - disulphide.  The mercapto compounds are prepared either by reacting the corresponding 6-hydroxy- or 6-halogeno-azapurines with a thiating agent such as phosphorus pentasulphide, sulphur or an alkali metal hydrogen sulphide or by the action of nitrous acid on the appropriate 4,5-diamino-6-mercaptopyrimidine.  The mercapto compounds are interconvertible by oxidation to their disulphides. In examples: (1) 8-azaguanine and phosphorus pentasulphide are refluxed in dry pyridine to give a mixture of 2-amino - 6 - mercapto - 8 - azapurine and the corresponding disulphide which are separated by extraction with ammonium hydroxide, the latter being insoluble; (2) 4-amino-6-chloro-5-nitropyrimidine is converted to 4,5-diamino-6-mercaptopyrimidine by heating it with potassium hydrosulphide solution and passing hydrogen sulphide through the mixture, and the product on treatment with sodium nitrite and glacial acetic acid yields 6-mercapto-8-azapurine and the corresponding disulphide which are separated by dilute alkali. The disulphide is converted into the sodium salt of the mercapto compound by solution in hot isopropanol and addition of sodium and the free mercapto compound is liberated from an aqueous solution of the sodium salt by acidification; (3) 6-hydroxy-8-azapurine and phosphorus pentasulphide in pyridine give 6-mercapto-8-azapurine and its disulphide.

[Classes 98 (i) and 98 (ii)] Fluctuation,in average density from frame to frame which may occur in a negative through varying illumination during its exposure, or through fault in the camera or development procedure, and which fluctuation may result, finally, in flicker on the screen during projection, is counteracted by first printing and developing a master positive from the negative and then printing a positive from the negative with light transmitted through the master positive and uniformly diffused throughout the area of the printing aperture, the light for each frame of the positive passing through the corresponding frame of the master positive. A more specific aspect involves development of the master positive to a gamma approximately equal to the reciprocal of the Callier Q of the stock on which it is to be printed, Callier Q meaning .the ratio of the specular density to the diffuse density of such stock when that stock is developed to a gamma in the region of 0.70. Preferably the printing light is diffused before it passes through the master positive, and the latter is fed through one aperture and the positive and negative are fed in contact with each other through another aperture which is in spaced alignment with the first aperture. Colour separation negatives representing the blue, green and red aspects of a scene may be so treated and, ordinarily, the fluctuation-free positives produced are used to make corrected negatives from which the final prints are made.
