Abstract: 471,401. Valves. KAMMER, G. S. Dec. 7, 1936, No. 33558. [Class 7 (vi)] [Also in Group XXVI] A valve 10 rotates between inner and outer stationary cooled members, and the material and valve thickness are such, and the clearance between the valve and the inner and outer members is such, that due to pressure and temperature the valve is deformed and presses tightly on the inner member adjacent the cylinder, and on the outer member on the opposite side. There is no clearance between the valve and the inner member when in a cold state, but a clearance amounting to 4 to 6 per mil. of its diameter is left between the valve and outer casing in a cold state. The working cylinder has a head with a cylindrical bore and water jacket 3. The inner water-cooled member 4 is formed with inlet and outlet passages 8, 9 communicating with cylinder inlet and outlet ports 6, 7. Packing-rings 14, 15, 16 are arranged as shown. The cylinder gases press the valve, against the cylinder 4 and close the passages 8, 9. The axis of the valve may be perpendicular to the crank-shaft in air-cooled engines. Cooling-ribs may be provided on the inside of the cooling-spaces in the member 4. A separately-driven expansion valve may surround the valve 10.

Title: Improvements in or relating to the automatic regulation of steam boiler furnaces
IPC: F23N1/02
Filed: 1927-12-14
Abstract: 282,411. Siemens - Schuckertwerke Akt.-Ges., (Assignees of Siemens-Schuckertwerke Ges.). Dec. 18, 1926, [Convention date]. Regulating combustion.-The fuel and air supply and draught of a group of boiler furnaces are regulated in accordance with the steam requirements by the aid of a master regulator controlled by the flow of steam in the steam main leading from the boilers to vary the flow of an auxiliary medium through a circuit comprising branched conduits corresponding in number to the number of boiler furnaces to be controlled. The flow of the auxiliary medium in the branched conduits is utilized to regulate the fuel and air supply of the individual boilers while by varying the flow in each branched conduit independently, the share of each boiler in the total steam generation is controlled. As shown in Fig. 1, a constriction 3 in the main steam pipe 4 is used to produce a differential pressure in accordance with the velocity of steam. Such pressure difference acts upon a diaphragm 2 to operate the valve 8 of a servo motor and control the position of a piston 11 adapted to operate a valve 15 for controlling the flow of fluid in a circuit 17, 18, 24, 26 comprising a pump 16 and tank 25. An increased flow of steam in the main 4 produces an increase of flow of the auxiliary medium and by means of a constriction 19 in the pipe 17 the pressure difference on each side of the constriction is transmitted to the diaphragm 20 and the valve 8 is returned to its central position. Branched conduits 21 in the auxiliary circuit correspond to the number of boiler furnaces to be controlled, and these conduits are further subdivided at 22. 23. Valves 40 control the flow of fluid in the conduits 21 to vary the share of each boiler in the total steam generation. Constrictions 41, 27, 28 are also provided, the constrictions 41 being employed in connection with measuring devices 42 to measure the share which each boiler takes in the total steam generation, while the constrictions 27, 28 are employed in conjunction with devices for varying the air and fuel supply respectively. The pressure differences on each. side of the constriction 27 and of the constriction 36 in an air supply conduit 27 are transmitted to diaphragms 29, 30 on the spindle of a valve controlling a servo motor the piston 32 of which controls the switch lever 33 of the motor for operating the blower. The pressure differences on each side of the constriction 28 and of a constriction 38 in a conduit 39 through which fluid is circulated by a pump driven in accordance with the speed of the grate and therefore the rate of fuel supply are transmitted to diaphragms 29<1>, 30<1> on the spindle of a valve controlling a servo motor the piston 32<1> of which controls the switch lever 33' for regulat. ing the speed of the grate motor. The flue damper may be similarly controlled.

Filed: 1936-12-14
Abstract: 487,231. Loom picking motions. TEFAG TEXTIL - FINANZ AKT.-GES. Dec. 14, 1936, No. 34256. Convention date, Feb. 28. [Class 142 (iii)] In a picking-motion wherein a picking lever 1 is operated by releasing a locked spring, the residual energy of the picking mechanism is dissipated, after the pick, by a hydraulic or pneumatic dashpot which permits a continued movement of the picking mechanism after completing its effective picking stroke. As shown in Fig. 1, the lever 1 is operated by a spring 6 controlled by toggle mechanism 21, 22, and carries a lug engaging a plunger 11 that is movable in a sleeve 12 within a liquid containing tank 13. On completion of the effective picking stroke I-II the plunger enters a recess 14 in the tank base and forces the liquid past a spring controlled valve 16 through a conduit 17 into the tank. When the plunger moves upwards, the recess is brought into communication with the tank by bores 20 and a valve 19 in the plunger. In a modification, Fig. 3, the lever 1 is operated by a spring 6 engaging a piston 32 in a cylinder 33, the pressure on opposite sides of the piston being equalized, when in position I, by recesses 38 in the cylinder wall and by means of a conduit 40 controlled bv the cross-head. On release of the spring, the crank 1 moves sharply to the left and on passing the recesses 38, compresses air in the chamber 34 until completion of the effective picking stroke (II) and further until position III is reached when the chambers 34 and 36 are brought into communication by recesses 37 in the cylinder wall. The Specification as open to inspection under Sect. 91 comprises also a form wherein the picking lever 1, Fig. 5 (Cancelled), is carried by one end of a shaft 41, the other end of which is secured against rotation at 42, and is connected by a rod 44, Fig. 6 (Cancelled), to a crank-pin 45 on a disc 54.
