A shoe construction is described in which a molded cup is provided with a flange extending outwardly from a top edge of the molded cup. A lasting margin of the upper of the shoe is wrapped around the outwardly extending flange and terminates on an exterior surface of the molded cup. The shoe is constructed such that the wearer's foot rests on an upper surface of a base of the molded cup. The outwardly extending flange is located some vertical distance above the bottom of the wearer's foot. The o...

A construction machine of the present invention is provided, in a compartment formed by a cover, with an engine, a centrifugal fan, and a heat exchanger for exchanging heat between cooling air blown by the centrifugal fan and a specified medium, wherein the centrifugal fan and the heat exchanger are arranged further upstream than the engine with respect to flow of cooling air, so that cooling air sucked in by the centrifugal fan is led to the engine after passing through the heat exchanger.

An improved valve construction having increased flow/pressure characteristics. The valve comprises a molded valve body including a plurality of body sections each having a generally flat inner surface, and the inner surfaces are disposed in contiguous relation along an interface. Each inner surface is formed with a plurality of recesses that mate with and complement recesses in the inner surface of the other body section to form a valve chamber and a connecting piston chamber. A spool valve is m...

A mixing and measuring tool formed of high molecular high density polyethylene enables a mason to precisely mix and provide an accurate amount of mortar to each brick saving wasted mortar. The tool presents a frictionless, hard cutting surface for cutting brick or stone. Due to the durable characteristics of the high molecular high density polyethylene, the tool surface will not absorb fluids during mixing yet withstand intense cutting or scraping without damage.

An outdoor sign construction comprising an inverted U-shaped wire frame and a rectangular corrugated plastic face panel. The sign face panel is retained on a horizontal header section of the frame between vertical frame legs by a resilient extruded plastic channel assembled around the header and out the top edge of the panel. The panel can be allowed to swing on the frame header or can be fixed against such movement by optional brackets. A secondary header and auxiliary sign panel can be assembl...

It has various layers in its structure: the lower layer (2, 2', 2") is a resistant base of ceramic origin or similar; the upper layer is a lamina (1) with a visible surface. The two are stuck by an adhesive defining a homogenous intermediate layer (3) without the formation of fragile zones due to the absence of air bubbles since the contact face of the ceramic base (2, 2', 2") is domed, the central point being higher than the rest. For preventing the surplus adhesive from flowing out and becomin...

A chair has a seat back with removable front and rear upholstered covers. The covers are held to the back by hidden release levers which prevent unauthorized removal of the covers.

A chair includes a base having a control, and a seat and a back tilt bracket pivoted to the control for synchronous movement. An extension is adjustably supported on the back tilt bracket and is pivotally connected to a back support structure and a backrest frame in a four-bar linkage arrangement. The extension is adjustable to change the angular position of the back when in the rest position, and further provides a back tilt axis that is located rearward of a rear edge of the seat, which provid...

A construction machine having an engine arranged along a counter weight, wherein the intake air pipe of the engine is passed between the counter weight and the engine without the need of installing the counter weight spaced from the engine, so that the counter weight protrudes outwardly less. This is accomplished by a piping space (44) of a recessed shape formed in the surface (36) of the counter weight (18) facing the engine (4) allowing the intake air pipe (28) to pass therethrough.
