Abstract: 199,563. Poole, E. C. May 10, 1922. Sounding-apparatus; recording-clinometers.-In an instrument for surveying the bed of a body of water of the type in which the horizontal measurements are recorded by the actuation of a chart from the rotation of a drum rolled over the bed to be surveyed, and the vertical measurements are recorded by actuation of the marking pencil from a piston subjected to the pressure of the water at the depth at which the drum is located, the chart and the pressure cylinder and piston are carried by a towing vessel, and the cylinder is connected by a fluid-tight conduit to a pressure chamber carried by'the drum. The drum is formed in two portions a. of known circumferential measurement, separated by the pressure chamber y and mounted on a common spindle b, and each portion is provided with angle-irons, spikes, or ribs d. The ends of the spindle b are mounted in a yoke c provided with towing loops and with counterbalance weights e. The spindle drives, through bevel gears f, g, a flexible transmission member h connected through change-speed gearing k to a pinion j which drives through reducing gears l a gear wheel m on the shaft of a roller o supporting the material of the chart. The flexible member h passes through a fluid-tight flexible tube which connects the pressure chamber y to the space below the piston s. The chamber y is open to the water at z, preferably through a trailing tube z<1>, and the air connection to the tube i is maintained by mounting loosely on the spindle b a counterweighted arm y<1> supporting at its upper end the free end of a flexible pipe i<1> communicating with the tube i. The marking pencil is fitted in a holder p on a carrier q mounted to slide on bars r and connected to the piston s and to a counterweight u by cords v passing over pulleys w. An adjustable spring t maintains the pencil normally in zero position. In a modification, the member h its actuated from the spindle b by an eccentric sheave on an eccentric disc secured to the spindle, and drives the roller o through ratchet mechanism.

Abstract: 454,976. Valve circuits. RADIOVISOR PARENT, Ltd., 28, Little Russell Street, Bloomsbury, London, POOK, H. W., Widmore Lodge, Widmore Road, Bromley, Kent, and IVE, G. A. G., 199A, Stanstead Road, Forest Hill, London. May 4, 1935, No. 13318. Addition to 430,439. [Class 40 (v)] In a modification of the circuit arrangement claimed in the parent Specification, a glow-discharge tube 9, the winding 10 of a relay and a unilateral conductor 6 are arranged in series across a light-sensitive cell 1 and an inert resistance 2, a condenser 5 being connected between their common point and the junction of the discharge tube 9 and the rectifier 6. With this arrangement, increase in voltage drop across the cell 1 on reduction of activation by light is not immediately accompanied by a corresponding drop across the resistance 2, since the condenser 5 can only discharge slowly across the rectifier 6. The rise in potential across the cell-resistance combination thus causes the tube 9 to strike and the relay 10 is actuated to close an alarm or other circuit. A second condenser, of lower capacity than 5, can be connected across the cell 1.

Title: Hydropneumatic Suspension
IPC: B60G17/04
Filed: 1968-03-22
Abstract: 1,170,566. Wheel suspension units. INDUSTRIAL DEVELOPMENT CO. ETABS. 22 March, 1968 [29 March, 1967; 19 June, 1967], No. 13903/68. Heading F2S. In a hydropneumatic suspension for a vehicle wheel 3 connected by a lever 1 to a point 4 on a vehicle body, the lever engages the rod of a piston 7 in a cylinder 8. Liquid 11 above the piston 7 is loaded by a gas spring 13 and liquid 30 below the piston is loaded by an auxiliary gas spring 35. The latter liquid also communicates with a valve 25 by which, in response to a decrease or increase in the vehicle loading, either a line 23 leading to a pressure source or a return line 28 is connected to the below-piston liquid 30. Normally, i.e. at constant load, the liquid 30 communicates with neither of these lines and the total suspension load is the vehicle load plus the hydraulic pressure loadacting upwardly on the piston. If the vehicle load decreases, the pressure in line 12 connected to the above-piston liquid 11 also decreases, the connection from line 12 through elements 14, 15, 16, 19 to the valve 25 can no longer maintain the valve in the position shown against the supply pressure in line 22, and so the valve moves to a position (Fig. 2, not shown) in which a connection is established from supply line 23 by way of lines 27 and 26 to liquid 30. This increases the hydraulic upthrust on the piston 7 so that the total suspension load can remain at substantially its original value, and thus the spring rate of the suspension also retains its original value instead of, as is usual, varying hyperbolically with vehicle load. Similarly, if the vehicle load increases the hydraulic load is decreased by the valve 25 acting to interconnect lines 26 and 28. The suspension may be made self-levelling by connecting a suitable valve 36 in line 23 and operating it by a lever connection 37, 38 to the wheel supporting lever 1. Normally, valve 36 closes both pressure line 23 and a return line 40, but the appropriate one of these is opened and the other remains closed whenever the level changes. Action of the lever system 37, 38 is damped by a dashpot 39. Valve-operating lever 16, shown in Fig. 1 as pivoted at one end 17, may be extended leftward beyond this pivot, the left-hand end being loaded by a suitable spring, e.g. a coil spring (Fig. 5, not shown) or torsion bar (Fig. 6, not shown).
