A device for cooling the wheel assemblies of heavy duty vehicles such as trucks, trailers, and buses. The invention being comprised of air inducing scoops attached to air holes on the outboard side of a wheel disk. Upon rotation of the wheel, a powerful heat dissipating burst of air is generated, and then directed through air holes of the wheel disk and over the braking structure requiring no power except the rotation of the wheel for drawing air therethrough.

A camera including a lens cover and provided with a plurality of picture taking modes. The camera has the capability for outputting a signal representing that the lens cover is open or closed, for selecting one of the plurality of picture taking modes and for sending a photographic film. The camera has a first display portion for displaying the picture taking mode selected and a second display portion for displaying information of the photographic film loaded in the camera. The operation of the ...

A pneumatic tire comprises a plurality of main grooves in a tread of the tire. The main grooves substantially circumferentially extend and are spaced apart from each other in an axial direction of the tire. Each the main groove is continuous. Intersection angles between an equatorial plane of the tire and tangents to each the main groove are larger from a starting end to a terminal end of the main groove opening at a tread end of the tire. Th pneumatic tire further comprises a plurality of sipes...

Inverters including complementary transistors and single ended or center tapped sources of current supply.

A fluid-filled flexible tube compressed between at least one roller and another surface. The viscosity of the fluid and the space between the roller and the surface determine the amount of snubbing available.

A waste incinerator including separate burning-, blower-, chimney- and ash-receiving chambers. A suction-discharge port is provided in a wall between the burning chamber and the chimney chamber for discharging gases from the burning chamber through a chimney to the atmosphere. The chimney extends from the chimney chamber for discharging gases to the atmosphere. The chimney receives an air feed pipe from the blower and an ignition sleeve extends into the chimney for burning unconsumed waste gas. ...

In a die including a cam member, which can be compactly designed in addition to the necessary function given to a cam member, in order to accomplish high quality machining without moving the cam member in a serpentine fashion, the die includes a slide cam having a slide cam base on the top of which a polyhedral guide portion is formed, the slide cam which holds and supports the polyhedral guide portion of the slide cam base being slidable along the polyhedral guide portion, and onto which machin...

A touch-trigger probe is provided with a sensor (which may be a mirror (106), an optical fibre (206), or a bi-refringent element (307)) which changes state by vibrating or undergoing strain when a stylus connected to the probe contacts a workpiece. The sensor is typically provided on (in the case of the mirror (106)), or in (in the case of the optical fibre (206)) the stylus. The change of state of the sensor causes a change in the path length, polarization state, or intensity of light waves con...

A folio or folder comprises at least one main body portion and at least one pocket rigidly connected, on two sides thereof, to the main body portion. Punched out from the flat material of the pockets or of the main body portion, by virtue of a U-shaped punched cut, is at least one filing tongue which can selectively be folded along a folding edge, and is thus capable of being folded outwardly. With the aid of filing perforations provided in the filing tongues, the folio may be filed within a fol...

A vacuum cleaner includes a motor, a housing enclosing the motor, a fan driven by the motor for producing a vacuum, a canister removably attached to the front end of the housing and having an intake nozzle for reception of foreign matter, liquid and air drawn into the canister in response to the vacuum developed by the fan. The intake nozzle includes a converging section extending from the front of the nozzle towards the center thereof and a diverging section extending from the terminus of the c...
