Title: Elastomer-Covered Rollers.
Inventor: BARCLAY IAN
IPC: B29C70/68
Filed: 1966-06-01
Abstract: 1,193,071. Printing rollers. DUNLOP CO. Ltd. 30 May, 1967 [1 June, 1966], No. 24402/66. Headings B6C and B6G. [Also in Division B2] A smooth-surfaced, elastomer-covered roller for use in printing is produced by applying to the elastomer-covered roller core by a latex dipping process a smooth coating of elastomer. The elastomer-covered roller core may be made by wrapping plies of unvulcanized elastomer composition around a spindle and vulcanizing the elastomer composition, if necessary grinding the elastomeric surface obtained to produce an even cylindrical surface. The wrapped elastomer layer of the roller may be solid or cellular natural or synthetic rubber. The smooth coating of elastomer may be formed from a natural or synthetic rubber latex, e.g. a butadiene-acrylonitrile latex. The coating of elastomer may be separately produced by forming a sleeve of elastomer by a dipping process and subsequently fitting the sleeve to the rollers by means of adhesives. In the example a steel spindle was cleaned by shot blasting, and coated with a chlorinated rubber. Unvulcanized synthetic rubber sheet was wrapped around the spindle and the synthetic rubber was then vulcanized. After vulcanization the roller was ground, coated with an adhesive, and dipped into a butadiene-acrylonitrile latex. The roller was then immersed in a solution of calcium nitrate to coagulate the coating. The dipping and coagulating processes were repeated to deposit a second latex coating on to the first and the roller was finally dried and vulcanized.

Title: Improvements in and means for measuring levels of liquids in containers or the like
IPC: G01F23/24
Filed: 1926-10-04
Abstract: 271,708. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 4, 1926. Indicators, electric.-The level of a liquid is measured by making use of the change of resistance of a wire surrounded by an electrically heated pipe partly immersed in the liquid. The wire c is connected to a source of current h through an ammeter g and an iron wire lamp e, and the voltmeter f indicates the voltage across the wire c. The surrounding pipe i is heated by current supplied from a source k through an iron wire lamp l which keeps it constant. The pipe i and wire c may be connected at one end. The voltmeter f indicates the resistance of the wire c if the current is kept constant, and the resistance varies with the mean temperature, which depends on the length of wire kept cool by the immersion of the surrounding pipe in the liquid. Errors due to changes of temperature in the container may be avoided by means of a counter voltage produced by a resistance subjected to the same temperature changes but not heated. If the voltage applied to the wire c is kept constant, an ammeter may be employed for indicating the liquid level.

Title: Improvements in or relating to thermostats
IPC: G01K5/62
Filed: 1919-10-08
Abstract: 158,931. Grundy, H. H. Oct. 8, 1919.. Thermal switches; mercury switches.-Relates to thermostats of the type such as described in Specifications 5311/12 and 110,938, in which an operating member A, Figs. 1 and 2, composed of one or more bi-metallic strips is adapted to actuate a rocking-switch B controlling the heating or cooling means. In order to obtain a better regulation of the temperature at which the thermostat responds, both the rocking-switch and the bi-metallic strip are capable of adjustment independently of each other, the coarser adjustment of the bi-metallic member being obtained by pivoting it at A<3> on a supporting bar H<1> and by operating screws A<4> bearing upon the sides of the member A, and the finer adjustment of the rocking-switch B being obtained by mounting the switch on a carrier F slidable in a slotted curved plate G, Figs. 3 and 4, and operated by means of a rotatable threaded rod L engaging a nut K on the carrier. In order to allow the switch to move in a curved path while the nut K traverses a straight path, the nut is provided with trunnions K<I> engaging slots F<1> in the carrier. The rocking-switch is pivoted on a spindle C on the carrier, and a stop B<1> is mounted on the carrier to limit the movement of the switch in either direction. The support H for the plate G and rod L is in the form of an annular member supporting a cylindrical casing M having apertures for the passage of the strip A and rod L, the various apertures facilitating circulation of the air around the switch. The strip A is preferably surrounded by a casing carrying a thermometer. In place of a single bi-metallic strip A, two strips A, Fig. 7, connected at their lower ends and normally splayed apart at their upper ends but held together under tension by a connecting piece A<5> may be employed. The two strips A may either be straight or substantially U-shaped or coiled in reverse directions, the metals being so arranged that the free ends tend to move in the same direction under variations of temperature.

Title: Process for applying pulverulent material to a surface
IPC: B24D18/00
Filed: 1959-07-17
Abstract: 900,148. Coating with powder. POLYMER CORPORATION. July 17, 1959 [July 18, 1958], No. 24633/59. Class 93. Infusible powder is applied to the tacky surface of an article, e.g. a surface capable of being rendered tacky by heat, by forming a fluidized bed of the powder consisting of a dense phase bounded by an upper free surface by pass ing an ascending dis tributed gas current therethrough and immersing the surface in the dense phase. As shown, the apparatus 10 comprises an open container 12 divided into upper and lower chambers 14, 16 by a porous ceramic plate 18. Air or nitrogen under pressure is blown into the lower chamber 16 through valve 21 and pipe 20, causing the upper surface 26 of the powder mass to rise to an equilibrium level. After coating, the base may be further heated to improve the bond and, where the base is of thermosetting material, to effect curing. The powder may be of aluminium, gold, zinc chromate, titanium dioxide, a solid lubricant such as molybdenum disulphide, tungsten disulphide or graphite, or a friction increasing agent such as aluminium oxide, silicon carbide, silica or magnesia. The tacky layer may be of a cellulose lower fatty acid ester, polystyrene, an epoxy resin, bitumen, asphalt, shellac, or mixtures thereof. A tacky layer may be applied to an article by immersing the heated article in a fluidized bed of powdered material capable of being rendered tacky by heating, as described in Specification 759,214. In Example 1, a steel shaft preheated to 650‹ F. is immersed in a fluidized bead of powdered polyhexamethylene adipamide and then in another fluidized bed of powdered molybdenum disulphide. Excess powder is removed by an air jet and the shaft is heated for a short time at 650‹ F. In Example 2, powdered plasticized heat stabilized cellulose acetate-butyrate and aluminium powder are similarly successively applied to an aluminium rod. In Example 3, cleaned and sandblasted aluminium is heated to 320‹ F. and given a very thin coating of mixed epoxy clear resin in a fluidized bed and is then given a zinc chromate powder coating in another fluidized bed. Excess powder is removed with an air blast and the resin is cured at 300‹ F. Example 4 is similar to Example 2. Example 5 is similar to Example 1 using a sandblasted aluminium plate. Specification 900,149 also is referred to.
