IPC: F27B7/28
Filed: 1934-01-23
Abstract: 432,213. Rotary furnace linings. SCOTT, W., Whydah, Claremont Gardens, Monkseaton, Northumberland. Jan. 23, 1934, No. 2356. [Class 51 (ii)] A rotary melting-furnace has an inner lining 9 of refractory brick laid on rammed ganister 6, which, for at least the main body portion of the furnace, is about half the thickness of the brick. The lining is built up from one end of the furnace to the other preferably by setting up rings of bricks and ramming the ganister into the space between the bricks and the outer casing 1. Shaped bricks 5, 8 are employed where the diameter of the furnace makes abrupt changes. In a modification the bricks are tongued and grooved to interlock. When a basic lining is required a layer of neutral chrome bricks may be interposed between the basic bricks and the ganister.

Title: A pneumatic driving device suitable for use in advertising apparatus having interchangeable signboards
IPC: G09F11/34
Filed: 1924-01-30
Abstract: 210,781. Hasselberg, B. A. L., and Ostberg, K. G. Jan. 31, 1923, [Convention date]. Addition to 193,421. Sheets, travelling.-A modified construction of the apparatus described in the parent Specification comprises a motor-driven air-pump 23 discharging into a conduit 31, which may act as an adjustable reservoir, containing a valve 32 admitting air automatically at intervals to cylinders 45. The valve 32 contains a spring-pressed seating on a portion only of which the pressure is exerted before the valve is opened, after which the air acting on the whole of the seating keeps the valve open till the pressure is considerably reduced. Each cylinder 45 contains a piston 46 to which is attached a wire which passes round a pulley 48, by which it is gripped, and is connected to a long helical spring which returns the pulley 48 and the piston 46 to their original positions when the charge of air has leaked past the piston 46. To the pulley 48 is fixed a ratchetwheel which engages a pawl on a surrounding sleeve 55 carrying a pin to which is fixed the outer end of a spiral spring the inner end of which is attached to the pulley 11. The pin directly turns the pulley 11 by contact with a rubber stud thereon, and when the pin is stopped by a brake actuated by a bead on the wire the pulley 11, together with the driving belt 8 and leaf-shifting roller 6, continue their motion by inertia, against the action of the spiral spring, till stopped by a second stud engaging the pin. The spiral spring then returns the pulley 11 and belt 8 through part of a revolution, thus providing the motion requisite to bring the leaf-feeding springs again to their lower position. Specifications 197,959 and 210,775 are referred to.

Title: Improvements relating to means whereby one fluid pressure is to be controlled in accordance with another
IPC: F15B1/00
Filed: 1944-02-10
Abstract: 605,437. Fluid-actuated valves. POWER JETS, Ltd., and McLEOD, R. C. Feb. 10, 1944, No. 2519. [Class 135] Apparatus for controlling one fluid pressure in accordance with another comprises flow regulating means such as a valve adjustable by a lever to regulate the controlled pressure, a member pivotally connected to a piston or the like subject to the controlling pressure and adapted to exert a turning moment on the lever about to pivot, and a second piston or the like also subject to the controlling pressure and adapted to vary the turning moment exerted on the lever. A particular application of the invention is to the secondary fuel supply of a jet-propelled aircraft, the arrangement being such that the pressure of the secondary fuel supply varies as the square of the pressure of the primary fuel supply. As shown, the controlling pressure acts through a common pipe 44 on a piston 6 slidable in the head of a casing 1 and on a movable cylinder 22 slidable on a fixed pipe 21. The casing 1 is provided with an inlet 13 controlled by a valve 37 and with an outlet 8. The valve 37 is allowed to open more or less under the control of the piston 6 through a pivotally mounted strut 16 bearing through a roller 15 against a lever 9 having a fixed pivot 10, a nose 43 on the lever engaging the valve 37. The conical upper end 18 of the rod 16 has a bearing 4 in the piston 6 and the roller at its lower end is mounted on a pivot 38 by means of ball bearings 3. The pivot 38 is connected to the cylinder 22 by parallel links riveted together at 31 and supported on the cylinder 22 by trunnions. The cylinder 22 is urged to the left by a spring 20 having a ball bearing 34 at its outer abutment to prevent the spring twisting under compression. The shape of the upper surface 19 of the lever 9 is an arc centred at the tip of the conical part 18, but it may be shaped in other ways. The line of action of the cylinder 22 may be varied and it may act to move the fulcrum of the lever 9 instead of the rod 16. The piston 6 may also operate against spring resistance. The lever 9 may control a variable delivery pump instead of the valve. According to the Provisional Specification, the piston 6 may be replaced by a diaphragm.
