A padlock having a "U" shaped shackle, a main body having an opening to receive at least one leg of the shackle, the main body having an interior which defines a recess within which a lock bolt body can be threadedly admitted, the lock bolt body having one catch to engage at least one leg of the shackle. A key rotates the lock bolt body between a locked, an unlocked, and a disassembled position.

Loose particulate material A, preferably housed in a capsule C, is urged towards the blind end of a borehole H. An anchor element 1 having an end plate 3 or a head and a disc spaced from the head is driven into the hole with rotation to compact the particulate material to form a load bearing annulus. The material is selected to be of a defined aggregate crushing value.

A fuel cell and mold therefor, which fuel cell is characterized by a molded plastic fuel container having a fuel pick-up opening in the top thereof and a molded wedge provided in the bottom thereof in angular relationship, which molded wedge serves to isolate and accumulate small quantities of fuel when the fuel cell is almost empty, to facilitate more efficient retrieval of fuel from the fuel cell. The fuel cell is molded inside a two-piece mold provided with mating flanges and a wedge blade sl...

A bath cabinet employs a fully concealed hinge and opening device, so that only the mirrored face of the door is seen on the front of the cabinet. The hinge bar is universal for left or right hand application and is affixed to the mirrored door. A cam arrangement, associated with the frame of the cabinet and a bumper mounted on the door, serves to selectively move the door out of the plane in which it rests when fully closed, to facilitate further opening of the door by grasping of an exposed ed...

A phototreating method comprises the steps of introducing a photoreactive gas into a chamber housing a workpiece, emitting first light substantially perpendicularly to a surface of the workpiece, and emitting second light substantially perpendicularly to the surface of the workpiece simultaneously with or after radiation of the first light. The surface of the workpiece is treated utilizing a photochemical reaction of the photoreactive gas caused by radiation of the first light and/or the second ...

A container (20) and blank (10) therefor are formed from a single blank of sheet material. The blank is easily folded and locked in shape into a food-receiving tube (20) with a bottom (50) at a point-of-sale for protecting foodstuffs placed therein from bruising or crushing. The foodstuffs in turn are used to help reinforce the container (20).

A grain cart includes an auger having a first lower section fixedly mounted to an inner portion of the cart and a second upper section pivotally mounted to an upper end of the first auger section and movable between a retracted, non-use position and an extended, use position. The auger's second section is folded inwardly and maintained in position within an upper portion of the grain cart by gravity when positioned in the retracted position. The second section of the auger is pivotally displaced...

A blade is provided for a digging implement, especially a snowthrower. The implement is of the type having an auger blade arranged for advancement sideways into a body of material to be removed. The blade consists of a band with a leading edge wound along a blade axis, preferably helically, and a tapered body that slopes towards the axis away from the material discharge of the device. In the case of a snowthrower, where the material discharge is at the center, the blade will have two sections, w...

A container construction which includes a pair of mating shells and in which a perimeter seal may be optionally used to provide a fluid tight seal and preferably a water tight seal surrounding an interior compartment of the container when the two shells are disposed upon one another. One of the shells is provided with an outwardly struck rim and a perpendicularly located shoulder. The second of the shells is also provided with an outwardly struck rim and also provided with a perpendicularly arra...
