Title: Compressed air vehicle braking systems
IPC: B60T8/18
Filed: 1972-02-01
Abstract: 1374693 Load and deceleration control of braking ROBERT BOSCH GmbH 1 Feb 1972 [2 Feb 1971] 4591/72 Heading F2F A compressed air vehicle braking system has a braking force regulating valve, connected in a compressed air supply line 29 to a brake cylinder pressure chamber 30 and having a member 10 displaced by vehicle load variation to limit pressure for the brake cylinder, and at least one wheel deceleration sensor to reduce braking pressure by connecting a counter pressure chamber 31 in the brake cylinder 30 to a source of compressed air, the counter pressure chamber being vented to atmosphere through a valve controlled by the member 10 when the deceleration sensor is not actuated. Vehicle suspension deflections and wheel rotation values are transmitted to a computer 4 from sensors 2, 2<SP>1</SP> and 3, 3<SP>1</SP> respectively, the computer supplying a signal to a spring biased electromagnet 9 to move the member 10 in the form of a frusto-conical sleeve, in turn actuating sleeves 15, 18 acting as closure members. Anti-skid actuation causes rapid movement of sleeve 15 to allow pressurized air to pass from the pressure chamber 30<SP>1</SP> via the 29, chambers 27, 35 and line 32 to the counter pressure chamber 31 to equalize pressures to retract the brakes. Load sensing causes slower electromagnet movement, decreasing load causing leftward movement of sleeve 10, and upward movement of the sleeve 18. Pressure fluid in chamber 27 acts on a diaphragm 22 with a series of rings 23 and a sleeve 21, causing the diaphragm to move down so that a neck 20 in the sleeve 21 engages a part 19 of the sleeve 18. The effective area of the diaphragm 22 decreases with downward movement due to successive rings 23 abutting the valve casing 12, and thus the pressure required to engage the neck 20 and the part 19 increases with such downward movement. Therefore, for decreasing load values, the valve closing pressure decreases, thus decreasing the braking pressure from the cylinder 30. During non-actuation of the anti-skid sensors 3, 3<SP>1</SP>, the counter pressure chamber 31 is vented to atmosphere through line 32, chamber 35, passages 36, 37, 38, 39, past a closure member 43 actuated by the sleeve 10, and through an exhaust passage 41.

Abstract: 1,241,663. Echo-sounding. MARCONI SOUNDING DEVICE CO. Ltd. 13 Nov., 1968 [30 Jan., 1968], No. 4743/68. Heading H4D. To reduce disturbing effects of reverberation when an echo-sounder is used in shallow water the transmitted acoustic power is controlled automatically in dependence on the water depth so that the power is lower for shallow soundings than for deep soundings. In a preferred embodiment a ramp-voltage generator is triggered at the acoustic pulse transmission instant and a gate is opened by the corresponding sea bottom echo to sample the ramp voltage. The sample voltage is applied via an amplifying and integrating stage to control the gain of a power amplifier which provides drive pulses for a transmitting/ receiving transducer. Echo signals are fed to a chart recorder which may also be used to trigger the ramp-voltage generator. The transmitted power may be controlled in dependence on the strength of received bottom echoes instead of on their occurrence time, and the power variation may be stepped instead of continuous.

Filed: 1930-02-14
Abstract: 348,204. Tunnelling. MOIR, SIR E. W., 10, Victoria Street, London. Feb. 14, 1930, Nos. 5000 and 33115. [Class 68 (i).] In driving tunnels or headings in water-bearing strata with the use of compressed air, the hydrostatic head of the water is lowered by providing one or more shafts, boreholes or headings at or adjacent to the site of the tunnel &c. and either permitting the water to drain thereinto to be removed by pumping &c., or forcing air out therefrom into the water-bearing strata. A shaft a is first sunk, as by use of compressed air, and closed near its lower end by a partition b provided with tubes c, e and air locks d, f for material and personnel. The upper part of the shaft is then used as a drainage shaft from which the water is pumped, and below the partition the shaft is sunk deeper with the aid of compressed air at a lower pressure than would normally be required. The water level along the site of the tunnel g is then depressed by driving headings h or i draining say into the shaft a, or sinking drainage shafts k, or both; alternatively or additionally, a pilot heading l may be driven within the section of the proposed tunnel and drain into a space say behind a partition m. The tunnel is then driven bv use of a shield j under compressed air at reduced pressure. Boreholes n are provided to indicate the hydraulic gradient. Under rivers &c. percolation may be reduced by dredging away porous soil and laying a clay &c. blanket q. After completion of the main tunnel, drainage apertures in the shafts a, k, or headings h, i may be closed to allow the shafts &c. to be used for pedestrians &c. Instead of draining the water from the soil, compressed air may be forced from the shafts a, k, headings h, i, l, or boreholes to form bubbles and so reduce the hydrostatic head. Both methods may be used in conjunction. Specification 303,685, [Class 68 (i), Excavating earth &c.], is referred to.
