Abstract: 627,073. Electric resonators. STANDARD TELEPHONES & CABLES, Ltd. Jan. 24, 1947, No. 2279. Convention date, Jan. 26, 1946. [Class 40 (viii)] In an ultra-high-frequency tuning system comprising a number of lines with ganged means for tuning each to resonance by adjustment of its length, a number of capacities, which can be finely adjusted and set, are spaced along the line to bring the length frequency characteristics of the various lines into agreement. The arrangement shown is a coaxial line 2 bent into a circle and provided with a rotatable arm 18 carrying a shorting member to vary the length of the line. The adjusting capacities are formed by small probes 21 with adjusting micrometer heads 20. In an alternative construction, the probes may be flat springs flexed by a micrometer screw.

Abstract: 463,288. Gas holders; tanks. WIGGINS, J. H. Jan. 29, 1936, No. 2688. Convention date, Feb. 11, 1935. [Classes 54 and 69 (i)] In a gas and/or liquid storage device having a top wall adapted to flex or move to vary the volume of the device, means are provided for causing the top wall to assume during its up and down movement the form of preferably spiral ridges separated by valleys. The gas holder shown comprises a flexible top wall A, a vertical shell C, and a bottom wall B having a flexible peripheral portion B<1>. The top wall A is provided with four weighted and stiffened portions produced by weights 1, spiral stiffening members 2 radiating from the centre and rigidly connected to the top wall, transverse stiffening members 3 secured to the members 2, and circumferential stiffening members 5, 6, connected by stirrups 7 to the top wall. When the gas holder is filled with gas the weighted and stiffening members cause the formation of ridges and valleys in the top wall so that rain deposited on the holder will either drain to the periphery or to a central sump 8 from which it can pass through a pipe 9 and cup 9<a> to a depression 10 in the bottom wall B fitted with a syphon drain 12. Emergency drains formed by flexible pipes 14 may also be provided. Excessive pressure in the gas holder is prevented by a relief valve E in the shell C, operated when the shell rises excessively, by a lever 26 attached by a chain 23 to an anchor 28. The top wall is prevented from waving in high winds by damping pistons 15 described and claimed in Specification 463,296.

Title: Improvements in or relating to broaching machines
IPC: B23Q5/06
Filed: 1935-01-18
Abstract: 447,515. Broaching-machines. KING, T. ST. P. C., c/o Lapointe Machine Tool Co., Ltd., Edgware, Middlesex. Jan. 28, 1935, No. 2809. [Class 83 (iii)] A double-acting hydraulic broaching - machine has a pump e supplying fluid under variable pressure to two alternately acting ram cylinders, a, b, the fluid being controlled by a valve having one position for synchronizing the ram pistons and two other positions for operating the respective rams. The rams are drawn downwards on their working strokes and the variable delivery pump e is fed through a line j from a reservoir h and discharges through a line k to a valve f having a central movable position provided with piston valve elements g<1> .. g4. These piston portions control the valve ports q, p, o, n respectively. Lines 2, 3 lead from the valve to the upper ends of cylinders a, b respectively and the lower ends of the cylinders are connected by a line 6, connected through a relief valve 7 and line 8 to the line y joining the valve f to the reservoir h. A branch 9 from the pipe y directs oil to the reservoir through the pump casing for cooling and lubricating the pump. The line 3 is also connected to the bottom of the cylinder b through a valve 5. In the neutral position, with the pump running, the ports are in the Fig. 1 position and the pump discharge passes through valve channel v port x and pipe y to the reservoir. The valve 7 prevents the rams from falling. To start the machine, the pump is set to a low delivery and the valve is manually moved to a position wherein fluid passes to the lines 3, 4, the valve 5 being open. This keeps the ram d down and moves ram c upwards, the relief valve 7 serving to prevent excessive pressure after both rams have reached their extreme positions. This synchronizes the rams and the valve 5 is then closed. When the ram c is to be moved downwards on its operative stroke pressure fluid is admitted to the upper end of cylinder a and oil from the lower end of cylinder a is transferred to cylinder b and forces the ram b upwards on its return stroke. The valve g is preferably actuated by automatic knockoff devices. At the end of the stroke of ram c the valve g is shifted so that pressure fluid is admitted to the head of cylinder b to operate the ram d and to return the ram c, the cycle thus continuing automatically.
