In an arrangement having an air-mass meter for an internal combustion engine, the measurement place of the air-mass meter is arranged within a flow channel which substantially circularly surrounds a hollow space connected with an intake opening of the internal combustion engine, said hollow space adjoining the interior...
An air flow control register includes a frame carrying pivotable vanes, which are rotated on parallel axes by a common drive mechanism, so that the setting of the vanes is variable between a maximum flow position, in which the flaps have a minimum inclination with respect to the direction of air flow through the regist...
Durable landing pads for a slider air-bearing surface (ABS) are formed of tetrahedral amorphous carbon (t-aC) by filtered cathodic arc deposition. A hard carbon overcoat of the ABS is pierced to anchor the pads. The t-aC is extremely hard and highly stressed, and the pads may be laminated with a stress-relieving materi...
An air cannon for removing cakes of flowable material and clearing clogged areas of flowable material in silos, heat exchanger and lines has a pressure container for storing compressed air and a pressure source connected to the pressure container. An outlet valve is connected to the pressure container. An outlet jet is...
A device for air flow rate measurement in the air intake tube of an internal combustion engine which has at least two temperature-dependent resistors in different branches of a bridge circuit having closed-loop electric current control, and which is characterized in that the temperature-dependent resistors are embodied...
A reduced-drag, axially symmetrical missile or submarine hull with rounded, tapered bow and stern portions, and a rounded central portion tapered, for drag minimization, along a curve defined by a Fredholm equation of the second kind framed so that the pressure coefficient remains constant at all points on the central ...
An air gap, venturi-type mixer for mixing a liquid chemical with water includes a readily field-exchangeable collimator, water seal and venturi unit to accommodate different flow rates. The venturi unit includes a funnel with slightly inclined walls that direct a misaligned collimated water stream into the vena contrac...
The invention is a combination of an air bag device and a vehicle. An air bag for the air bag device for a passenger seat or a rear seat is structured by superposing a lower panel and an upper panel and sewing up the peripheral portions of the panels. The lower panel is longer than the upper panel. Portions of the lowe...
A fastener driving tool in which tacks, connected at the head end thereof to form a flexible band, are fed seriatim by a reciprocating feed pawl from a magazine through a guide channel beneath a reciprocating driver which shears off the leading tack from the band and drives it into material located therebeneath. The fe...
A tunable air spring/shock absorber comprises a cylinder, a piston rod extending out of the cylinder through a lower end thereof, and rod guide provided on the lower end of the cylinder for guiding the piston rod, a seal mounted on the rod guide and piston containing valving components to deliver desired force-velocity...
An air/fuel control system for an engine (10) provides an air/fuel indicating signal linearly related to average engine air/fuel operation from a two-state exhaust gas oxygen sensor (76). Fuel delivered to the engine is modulated with a periodic or modulation signal (244). The modulation signal is offset in either a fu...
