Title: Pneumatic valve damping to improve air venting noise
Inventor: JAKE ANDREWS
IPC: F16K31/122
Filed: 2021-10-21
Abstract: Aspects of the present invention relate to an apparatus 100 for use in an air suspension exhaust system. The apparatus 100 comprises a valve 110 shaped at a first end to engage with a biasing member 130 and enclosing a first cavity 180 at least partially defined by the valve 110. The apparatus 100 further comprises a housing 120 configured to house the valve 110 and the biasing member 130. The housing 120 comprises an air inlet 140; an air outlet 160; and an exhaust channel 150 provided between the air inlet 140 and the air outlet 160. The valve 110 is movable between a closed position in which the valve 110 blocks passage of air through the exhaust channel 150 and an open position in which air can pass through the exhaust channel 150. The valve 110 comprises an aperture 115 provided through a wall of the valve 110 so as to allow air that flows through the exhaust channel 150 from the air inlet 140 to the air outlet 160 in dependence on a position of the valve 110 into the first cavity 180. An air suspension system including the apparatus 100, and a vehicle including such an air suspension system are also disclosed.

IPC: F27B3/10
Filed: 1987-08-27
Abstract: To save energy in the production of steel in an electric arc furnace while increasing the total input of energy, the employment of carbonaceous fuels and oxygen-containing gases is proposed. The oxygen or the oxygen-containing gases are led into the furnace in the upper part of the furnace through stationary top blow-in devices (4) into the space between the pitch circle of the electrodes (10) and the furnace wall (3). The resulting intense gas flow repeatedly sucks in the reaction gases arising from the scrap or the melt being formed and burns them. The heat thus set free is transferred to the scrap and/or the melt with a thermal efficiency of at least 70%. By nozzles (2) arranged below the surface of the bath, and preferably in the furnace floor, preferably oxidizing gases are led into the melt and solid materials, particularly carbonaceous fuels, are supplied to the melt through one or more hollow electrodes (6) with an abrasion-resistant cladding. With this process, increased energy input into the electric arc furnace becomes possible, and thus the melting down time can be shortened and the economy of the process improved.

Abstract: A blind rivet able to be anchored in material such as softwood, without the need to break through the blind face (36) of the material, comprises a tubular shell (14) and a stem (15) which extends through the shell. The shell (14) has a preformed head (18) at one end of a shank (17). An end portion (19) of the shank remote from the head (18) has a thinner wall (21) than the main, next adjacent, portion of the shank, and is thus weakened and made more easily expandible. The stem (15) has a plugging portion (28) having an expander head (29) adjacent the thin-walled end portion 19) of the shell, a breakneck (27), and a pulling portion (26) which projects from the head end of the shell. The expander head (29) increases in diameter away from the pulling portion (26), and presents a plurality of longitudinal cutting elements (24) generally towards the weakened end portion (19) of the shell. On gripping the pulling portion (26) and pulling the stem (15), the cutting elements split the end portion (19) of the shell into a plurality of legs (37), while the expander head (29) enters into the end portion (19) and forces the legs (37) outwardly. The main part of the shank (17) has a smaller diameter bore (20) than the weakened end portion (19), and resists entry of the expander head (29).

Abstract: The invention relates to a clamping device to link a tool head (11) with a tool holder (10) in machine tools, having a changeable tool head (11) which has a location spigot (13) which can be inserted into a corresponding location bore (15) in the tool holder (10). During clamping, clamping elements (20) are moved via the clamping device from inside to outside in recesses (25) of the location spigot (13). 
<??>In order to provide clamping paths which are as short as possible and thus reduced clamping times in a simple construction of the clamping device, the greatest clamping forces, with smaller displacement of the clamping elements, only being expended when the clamped state of the tool head (11) in the tool holder (10) is reached, the clamping device is designed as a rotatable clamping shaft (17) having guides (18, 19) running spirally for the clamping elements (20) and for the forcing element (21).
