Title: Improvements in or relating to spring suspension devices
IPC: F16F9/02
Filed: 1929-12-28
Abstract: 351,925. Pneumatic springs. JANECEK, F., Nusle II, Prague. Dec. 28, 1929, No. 39680. Convention date, Dec. 29, 1928. Void [Published under Sect. 91 of the Acts]. [Class 108 (iii).] In a vehicle suspension system a number of pneumatic springs of the cylinder and piston type utilizing air or air and liquid are connected to common high and low pressure reservoirs of large capacity, one of these vessels being supplied with air under pressure by a pump. The supporting unit, Fig. 1, consists of a piston 1 secured to the axle, a cylinder 2 secured to the vehicle frame and supplied with pressure fluid through the passage 6, and several floating pistons separated by springs and each provided with a small leak orifice. Connections 7, 8 to the low-pressure reservoir open into the cylinder in such a way that the piston 1 is automatically retained in the position shown whatever the load. In the modification shown in Fig. 2, fluid from the high-pressure reservoir is supplied through the pipe 11 while the pipe 12 leads to the low-pressure reservoir. When, due to a decreasing load, the piston 9 is forced downwardly out of the cylinder, the high-pressure opening 11 is covered and the low-pressure opening 12 is uncovered so that the downward movement of the piston is limited. Upward shocks are cushioned by a spring 13. The suspension cylinder shown in Fig. 4 is provided with a connection 24 to the highpressure reservoir, a connection 22 to the lowpressure reservoir and a connection 23 to the suction side of the pump. Four of these units indicated at I, II, III, IV are employed in the vehicle suspension system shown diagramatically in Fig. 6. The high-pressure and low-pressure reservoirs 16, 15 are connected by a valve 17. The supply of air from the high-pressure reservoir to the cylinders is controlled by a hand-regulated valve 25. Fluid escaping from the cylinders passes to the vessel 26 from which it is drawn by the compresser or pump 18. A modified system of somewhat simpler construction is shown.

In a superheterodyne vestigial sideband television receiver having automatic tuning and step-by-step channel switching the local oscillator frequency in changing over to a new channel is temporarily altered so that the vision carrier position lies at the maximum amplitude end of the sloping portion of the I.F. bass-band normally having the vision carrier centred on it. To this end the A.F.C. voltage applied to a back-biased variable capacity diode 10 controlling the oscillator frequency may be interrupted or short-circuited momentarily by a switch S connected with the coil turret channel switch 4. Alternatively, a point 14 in the oscillator anode circuit or an electrode voltage may be momentarily earthed or altered in potential or the frequency discriminator tuning may be temporarily altered during channel switching.
