Abstract: 274,784. D÷rstling, G. May 18, 1927. Roller apparatus.-In a roller mill for grinding or mixing chocolate, pigments, &c. and of the kind in which the rollers are controlled by weighted levers, a single lever system is arranged to apply uniform pressure to three or more rollers and to be operated to separate all the rollers from one another to a variable extent when a mixing rather than a grinding effect is desired. As shown applied to a mill with three horizontal rollers a', a<2>, a<3>, the bearings of the roller a<3> are provided with lugs n connected by rods o to crosspieces p which are adjustable on the rods o and arranged so as to form a carrier for the shaft of the roller a<2>. The bearings of the roller a<3> are connected to forked plungers l controlled by levers g pivoted at e to the machine frame. Rods k connect the levers g to levers h which are pivoted at f and loaded by weights t. A shaft q passing right across the machine has an arm r for each lever h, so that the levers may be operated to release the pressure on the rollers. The shaft q has a hand-lever s which can be secured in the adjusted position by means of a clamp-screw moving in a segmental slot w. When the lever s is moved to release the pressure un the rollers, the roller a<3> is first separated from the roller a<2> until the shaft of the latter is engaged by the cross-pieces p, and then the two rollers move together for separating the roller a<2> from the roller a<1>, which is mounted in fixed bearings. A scale may be provided on the slot w to indicate the separation of the rollers. The ends of the rod k are oppositely screwed and engage in forks i, i<1> of the levers g, h so that by turning a hand-wheel v the length of the rod k can be adjusted. The material is fed from a hopper c and delivered by means of a shoot d which serves also as a scraper. The rollers may be arranged horizontally or vertically, and the gearing b is such that each succeeding roller rotates slightly faster than the preceding one.

Abstract: 514,503. Thermally-actuated valves. SAFETY GAS DEVICES, Ltd., RABINOWICZ, M., and KESTENBAUM, I. May 7, 1938, No. 13702. [Class 135] A safety cut-off for the main gas burner of a water heater comprises a main gas valve actuated by a thermo-responsive member subject to the heat of an auxiliary burner the supply of gas to which is controlled by a valve actuated by means dependent on the water supply so arranged that in the event of the supply failing the gas supply is interrupted. In the form shown in the Figure the gas and water valves are arranged coaxially the gas cock d being actuated by a handle and the water valve a by a member f pivoted to an arm g on the valve spindle e. This member is normally pressed by a spring into operative engagement with an arm k on the handle l so that the gas cock is opened widely when the water valve is opened. By moving the member f against the action of the spring i it may be disconnected from the projection k to permit independent adjustment of the valves. The gas cock is urged to its closed position by a spring but when opened is returned open by a thermally-actuated catch in a manner similar to that described in Specification 505,894. The gas cock has a main gas passage p and two peripheral grooves r, v. The groove r is connected by a passage q with the main gas passage and is connected by a passage s with a chamber t in the cock casing. This chamber which houses the valve controlling the auxiliary burner is connected by a passage u, peripheral groove v and passages wand x to the auxiliary burner.

An output coupling for a cavity resonator comprises a conductor arranged within the cavity between an output terminal and an end wall, the conductor passing through a tuning piston and providing a variable output loop, whereby a constant bandwidth is preserved as the cavity is tuned over a wide range of frequencies. As shown, the internal and external conductors 8, 4 of a coaxial cavity are respectively connected to the grid 6 and anode 3 of a tube 1. A flat conductive strip 15 lies halfway between the conductors and extends from the central conductor 19 of a coaxial output socket 20 to an adjustable securing bracket 16. The strip may be made of conductive material or of an insulator coated with e.g. silver. The length of the active part 9 of the cavity and the length of the coupling loop formed by the strip are both varied by a piston 10 carrying resilient contacts which bear upon one or both sides of the strip. Constant bandwidth is obtained by adjusting the values of (a) the width of the strip, (b) the position of the strip between the conductors, (c) the axial position of the output socket. Two strips forming a parallel line may be used. The piston may be capacitatively connected to the strip and the strip or the coating of metal on it may be shaped to provide a capacitor electrode having an area which varies with the position of the piston.
