There are provided improved processes for the manufacture of enriched pitches, carbon fiber precursors, carbon fibers, and graphite fibers. The improvement comprises employing an elevated wiped-film evaporator in a wiped-film evaporator system comprising the wiped-film evaporator and a means for recovering enriched pitch, such as a positive displacement pump, to form an enriched pitch from catalytic pitch and regulating the operating conditions of the wiped-film evaporator system to provide the desired enriched pitch. The wiped-film evaporator is located a specific distance above the means for recovering enriched pitch. The vertical distance between the outlet of the wiped-film evaporator and the inlet of the means for recovering enriched pitch is within the range of about 10 feet to about 40 feet, preferably about 20 feet to about 40 feet.

A universal shoe holder having a detachable mounting member for securing the holder to a work surface, and a supporting member which supports the shoe holding mechanism perpendicular to the mounting member. The shoe holding mechanism consists of a holding member fastened to the support member, and a heel support member which is pivotally attached thereto. A tightening mechanism is provided which exerts pressure on the heel support member and the holding member, allowing the shoe holder to securely hold various styles and sizes of shoes during repair and polishing procedures. An adjusting mechanism is included to allow the shoe holder to be adjusted to fit different sizes of shoes.

A multipurpose brick-layer's tool is adaptable for use as brick tongs or as a mortar hoe. In one embodiment of the invention, the tool also functions as a band-cutter for cutting metal bands used in the packaging and transport of bricks. The tool is adjusted using a slide and guide arrangement. A pin and hole adjustment mechanism varies the distance between locking jaws of the multipurpose tool. In this manner, a specific number of bricks can be carried or a hoe handle of preselected length can be formed. An elongated embowed handle arches over the guide tube and has at one end thereof a first clamping jaw. The jaw end portion of the handle is rotatably affixed to a pivot pin extending through opposing walls of the guide tube. A slide tube carried within the guide tube extends outside the guide tube and carries a second clamping jaw complementary to and larger in size than the first clamping jaw. The second clamping jaw is a blade of a size and structure suitable both as a mortar hoe blade and a clamping jaw.
