An apparatus for straightening arrowheads is designed to be used to straighten bent arrowheads so that the arrowheads, once straightened, may later be used in archery activities. To straighten a bent arrowhead, one removes or retracts any blades of the arrowhead (if possible) and attaches the arrowhead to a rotatable shaft. The rotatable shaft is free to rotate through the shaft aperture in the shaft housing, and the shaft housing is attached to the base of the device. To straighten the arrowhea...

A wire straightening device (62) is disclosed for use on a wire processing machine (60). The device includes two wire deflection units (72, 74) arranged to deflect the wire in two perpendicular planes to remove stresses in the wire. Each wire deflection unit includes a first member (90) having a set of upper rollers (92, 94, 96) arranged thereon and a second member (110) having a set of lower rollers (112, 114, 116, 118) journaled thereon. The two sets of rollers are adjustable toward and away f...

An improved highly alkaline hair straightening emulsion and a two component system for preparing the emulsion are provided. The emulsion employs a combination of strong nitrogenous organic base and alkali metal hydroxide in the presence of an alkaline earth metal cation. Neither the amount of the alkali metal hydroxide nor the amount of organic base present in the emulsion is sufficient by itself to effectively permanently straighten naturally curly hair. Alkaline earth metal hydroxides are char...

An exerciser includes a base supported on a support in a suitable inclined angle for supporting a user. An extension is slidably engaged in the base and has one end extended outward of the base and has a clamping device for clamping the feet of the user to the extension. A bracket is secured to the extension. A lever is pivotally coupled to the base and a handle is secured to the lever for rotating the lever. A cable couples the lever to the bracket for moving the extension outward of the base a...

Apparatus for the straightening of vehicles, comprising a straightening bench for the vehicle and a vertical beam with a cylindrical body (1) having a piston part (2) movable inside it. The apparatus comprises a mounting base (9) fitted to the upper end (8) of the piston part (2) and moving along with it. Attached to the mounting base is a lifting beam (10) for producing the lift required in the straightening operation.

A vehicle repair and alignment apparatus for correcting and aligning misshapened vehicle frames and outer body panels comprises a frame having a pair of elongate track members with slotted rails provided along the outer edges thereof, vertical pull towers pivotably mounted on a respective semicircular platen slidingly engaged on each rail enabling selective angular orientation of the pull towers with respect to the track members, and two pairs of vertical bolster cylinders powerably positionable...

A plate straightening machine includes upper rolls and an upper frame rotatable from an operating position, at which the upper rolls face downward, to a non-operating position, at which the upper rolls face upward. The plate straightening machine further includes a mounting plate detachably attached to the upper frame so that the mounting plate can be moved toward either side of the path, and at least one upper roll replacing stand disposed on either side of the upper frame in the non-operating ...

A cyclone comprising a swirl cylinder, an inner tube disposed in the upper section of the swirl cylinder, an inlet duct arranged tangentially to the outer periphery of the swirl cylinder, a drop opening formed in the lower section of the swirl cylinder, and a straightening instrument disposed in a space directly below the inner tube. The straightening instrument includes a conical member coaxial with the inner tube and guide plates arranged along a conical surface at the outer periphery of the c...

A device for straightening a rigid wire delivered in coil form for supplying a metal-working machine is compact and easy to control. The wire is stationary in an axial conduit of a rotor supported on a carriage (B) which is moved axially by means of a first hydraulic jack (13). The rotor carries the wire by stationary guides and a central guide which is moved radially (C) between a centered position and an excentric position by means of a second hydraulic jack (62) while the rotor rotates and th...

An attachment for a hair dryer includes an upper body for supporting a heat transmissive plate with a comb extending from one side of the heat transmissive plate and a lower body for attachment to an outlet of the hair dryer. The heat transmissive plate is heated by the hot air exiting the hair dryer's outlet. The upper body of the attachment includes vents positioned about the heat transmissive plate for directing heated air generally in front of and behind the heat transmissive plate, and a pa...
