Title: A pH Determining System.
Inventor: CARDEIRO PHILIP H
IPC: G01N27/28
Filed: 1967-04-04
Abstract: 1,155,241. pH meter. UNIVERSALINTERLOG Inc. April 4, 1967 [April 13, 1966], No. 15441/67. Heading G1N. In a pH meter including an ion sensitive electrode 47, Fig.2, immersed in a stream of the liquid whose pH is to be determined, the electrode is connected to the gate electrode (G) Fig. 4 (not shown), of a field effect transistor 81. Whose output is fed to an amplifier (89) to be used for metering or control. By choosing an f.e.t. whose input impedance changes with temperature in an approximately similar but reverse manner to that of the ion sensitive glass bulb 53 of the electrode 47 and arranging it in thermal contact with the electrode 47 errors due to temperature changes are eliminated. Furthermore due to the low output impedance of the f.e.t. the output circuitry can equivalently have a low impedance. In a modification of the construction the f.e.t. is included in a junction box (not shown) situated adjacent the end of the electrode 47. If the f.e.t. is not in close thermal relationship with the glass bulb 53 or its temperature characteristic is not closely matched with that of the glass of the bulb, a reverse biased junction diode (101) or another f.e.t. may be connected between the gate electrode (G) of the f. e.t. 81 and a selectable positive potential, having a temperature coefficient of current leakage which is the same as that of the f.e.t. 81 so that the system is entirely independent of temperature variations. The pH meter comprises a composite container of e.g. polyvinyl chloride plastics or nylon, having two chambers (37, 39, Fig. 1, not shown), in communication via a plug 45 of wood or porous ceramic material. The chamber (39) contains a reference calomel or silver-silver chloride electrode 67 dipping into a saturated solution of potassium chloride. The glass bulb of electrode 47 is inserted into chamber (37) with its end adjacent the liquid inlet 57 so that it is continually cleaned by the liquid flowing over it. A fluid outlet 59 is provided at the top of the chamber. The electrode 47 comprises the ion sensitive glass bulb 53 attached to the end of an untreated glass tube 73 containing a saturated solution of potassium chloride into which a calomer or silversilver chloride electrode 79 dips. The electrodes 79 and 67 are made of the same material so that the two oxidation-reduction potentials of the electrodes are equal and cancel each other out in the measurement.

Filed: 1928-05-25
Abstract: 297,095. Goodyear Tire &. Rubber Co., (Assignees of Snyder, R. W.). Sept. 16, 1927, [Convention date]. Moulding wheel tyres.-A device for inserting air-bags into pneumatic tyre casings comprises means for engaging the beads and moving them apart in parallel relation and means for inserting the bag. Means are also provided for collapsing the bag before insertion. As shown, the device comprises a fixed cylinder 10 having a beadreceiving flange 34 adjacent to one end of which is arranged a head 42 furnished with a beadreceiving flange 43. The head 42 is carried by a piston working in a cylinder 11. At the opposite end of the cylinder 10 is arranged a piston 26, operable by a piston in a cylinder 9, which is adapted to force the air-bag 37 through the cylinder 10 into alignment with the casing 36. In operation, a casing 37 is positioned on a platform 38 to engage the flanges 34, 43. The airbag 37 is then placed in front of the piston 26 upon hinged supports 71 and is collapsed by a cranked member 70, depressed by a piston in a cylinder 61, and is held in collapsed position by turning the supports 71 as shown in Fig. 2 after which the member 70 is withdrawn. The piston 26 next advances the collapsed bag through the cylinder 10 into alignment with the casing 36. During this advance, air is permitted to escape through a valve 45. When the bag is in position, the valve 45 is closed and a valve 47 opened to admit compressed fluid which forces the beads apart and firmly against the flanges 34, 43. The head 42 is then retracted to move the beads sufficiently apart to allow the airbag to resume its normal shape and seat itself within the casing. Finally pressure is relieved by the valve 45 and the casing removed.
Patent GB-663823-A (GB)
Title: Improvements in or relating to method of producing a stably tacky eucohesive pressure-sensitive adhesive and the pressure-sensitive adhesive resulting from said method
IPC: C09J7/02
Filed: 1947-06-12
Abstract: A pressure-sensitive adhesive is made by heating a composition comprising a sub-rubbery, i.e. "pasty", butadiene-styrene copolymer and either an oil-soluble phenolaldehyde resin or an accelerator of the thiuram-polysulphide type to a stage where it is more cohesive than adhesive but still tacky and substantially free from after-vulcanization and tack-loss at room temperatures. The aldehyde resin may be made from para-substituted phenols, e.g. para t-amyl phenol and formaldehyde.  Specified accelerators are dipentamethylene-thiuram-tetrasulphide, tetramethyl-thiuram-disulphide and selenium diethyldithiocarbamate. The compositions, which may contain compounding agents such as zinc oxide, stearate or resinate, magnesium salts, rosin, terpene resins, ester gum, hydrogenated indene resins, fillers such as starch, clay, whiting and carbon black may be applied to backing-sheets, e.g. in the preparation of adhesive tapes (see Group VIII), dissolved in a volatile solvent, e.g. heptane, alcohol or suspended in aqueous media and the solvent or water removed and the composition brought to the desired adhesive state in situ.  The compositions may contain an excess of aldehyde resin or accelerator which may be utilized to harden the adhesive when in contact with the desired surface, e.g. in electrical insulating tapes.  In examples: (1) a sub-rubbery butadiene-styrene copolymer is made by heating in aqueous media, a mixture of the monomers in the presence of a polymerization catalyst, e.g. potassium persulphate, a fatty acid soap, and a chain terminator, e.g. dodecyl mercaptan, and stopping the reaction, e.g. by adding hydroquinone while the polymeric material is sticky and inelastic; (2) a paratertiary-amyl pheno-aldehyde resin is made by mixing in aqueous media the phenol and formaldehyde, adding potassium hydroxide, heating until the free formaldehyde is 2 per cent or less, adding acetic acid and evaporating in vacuo.  The Specification as open to inspection under Sect. 91 comprises also the use of copolymers of butadiene with isobutylene or methyl methacrylate, and copolymers of styrene with isoprene or methyl-pentadiene, polymers of butadiene or isoprene, and partially cross-linked interpolymers of isoprene and glycol dimethacrylate or diallyl succinate and also the use of accelerators consisting of sulphur or selenium in conjunction with copper diethyldithiocarbamate or piperidine pentamethylene dithiocarbamate.  This subject-matter does not appear in the Specification as accepted.

Filed: 1959-05-06
Abstract: 870,687. Printing-machines. GERICKE, E. May 6, 1959 [Sept. 4, 1958], No. 15513/59. Class 100(2) An offset rotary printing machine has a damping roller 10 co-operating directly with an inking roller 11, the roller 10 being damped by a roller 9 which dips into a fountain 12 containing damping liquid. The roller 9 rotates in contact with a second roller 8 which also dips into the fountain. The roller 8 is pressed by screwthreaded spindles having milled knobs 7 into contact with the roller 9, thus permitting variation of the thickness of the liquid film between rollers 8 and 9. Contact pressure between the roller 10 and roller 9 is determined by the weight of the roller 10 and pressure exerted by the inking roller 11. The lengths of the rollers 8, 9, 10 and 1 1 diminish in the direction towards the inking roller to avoid excessive transfer of damping liquid at the edges of the rollers.

Abstract: 675,570. Labelling machines. NEWMAN, R. J., and FRIEND, D. S. June 13, 1950 [June 13, 1949], No. 15637/49..Class 73. A labelling machine applies labels to cylindrical objects such as bottles by rolling them between an endless conveyer belt and a resilient plane surface after a gummed label has been initially attached to the object by reciprocating pressers. Horizontally reciprocated plates 33, 34, are gummed by passage under a vertically reciprocating transfer roller and then receive a label between them from the bottom of a vertically reciprocating label hopper before advancing to the labelling position. Bottles 100 are placed on a feed chute 6 at 95 and come to rest against a vertically reciprocating rest bar 81 which descends and allows the foremost bottle 100 to advance on to its sloping end 86 and to come to rest against a plate 87. The rod 81 then rises until it is just below the edge of the gum plate 34 in its advanced position at which point presser feet 63, 64 descend and pass through the opening 32 between the gum plates to attach and hold the left side of the label on the bottle. The rod 81 and presser feet then rise together until the bottle passes a wiper 106, which acts against the left end of the label, and then comes in contact with an endless conveyer belt 80, at which point the presser feet rise from the bottle, which is conveyed over a plane surface 99 which completes the wiping of the label, to a discharge chute 107. The plane surface 99 preferably has a resilient upper surface 101 of cork or rubber. All the parts are operated by cams on a main shaft 120 driven by an electric motor. The label hopper may be depressed into contact with a printing or stamping device to mark the bottom label while the gum plates are fully advanced. Specifications 581,853 and 625,363 are referred to.
