Tube Patch KitsREMA PATCH KITSMany years ago, Rema of West Germany, in essence redesigned the inner tube patch kit by improving the patch itself. Up to that time the patch itself was nearly 1/10th of an inch thick and cumbersome to use on a thin casing racing tire because it would produce a "thump" while rolling because of the added thickness. The old style patches also weren't as supple and frequently wouldn't contour and adhere to the tube. Rema's redesigned patches have a total thickness of just 6/10ths of a millimeter at the center ,which is its highest spot, with the thickness feathering into non-existence at the edges. This tapered edge patch is also sealed at time of vulcanizing, on top with cellophane and on the bottom with aluminum foil, to be air tight, to retain the suppleness of the soft rubber patch and nearly guarantees a 100% success rate when patching a tube. Rema makes their patches in two sizes which are used in their three different patch kits. Their F1 patch is a 20mm (.80") diameter circular patch and their F2 patch is 16mm (.62") wide and 43mm (1.7 inches) long. Each patch kit comes with a piece of emery cloth to "buff" or finely scratch the tubes' surface so that the rubber cement and patch have a clean surface to adhere to. All the kits come with a tube of rubber cement and pictorial instructions on how to properly patch an inner tube. There are Taiwan factories that make imitations of the Rema patch, but these don't exhibit the same quality of the original Rema patch they are copying, or work quite as well.
REMA 01 PATCH KITThe Rema 01 kit is the smallest of the three kits Rema makes. It includes instructions, emery cloth, a 2.8 gram tube of rubber cement, four of the F1 patches and one of the F2 patches. These are all in a small plastic box with a total weight of just 16 grams. $ Price in Catalog REMA 02 PATCH KITThe Rema 02 kit includes instructions, emery cloth, a 10 gram tube of rubber cement, six of the F1 patches and one of the F2 patches. These are all in a small plastic box with a total weight of just 27 grams. $ Price in Catalog

In-depth Information About Metals Aluminum Aluminum is extracted electrolytically from bauxite ore. It is made by the electrolysis of aluminum oxide which is found in larger concentrations within bauxite ore. Bauxite is a mixture of the hydroxides of aluminum, together with other impurities such as oxides of iron, titanium, and silicon. Bauxite is produced by the weathering and change of aluminum silicate rocks usually found in tropical and semitropical regions where climate has produced an accelerated weathering process. Bauxite is not a rare ore and is widely available in the US, the Caribbean, and Europe. Approximately 4 pounds of read the full article... Beryllium Beryllium is a specialty metal that is steel-grey metal in color, with an extremely low density, making it very light weight. At 1.85 grams to the cubic centimeter, its density compares to that of magnesium. It is also a high strength metal, making it possible to design light weight, thin membered parts with ahigh stiffness. A column made of beryllium to support a load placed directly downward on top of it, will have a greater load carrying capacity, and be lower in weight than any other metal of equal size. Until the 1950's beryllium was used read the full article... Titanium The element titanium was discovered in 1763 by an English cleric, William Gregor who was an amateur chemist with an inquiring mind. It was in the black sands of Cornwall that he discovered the new element that had up to that time, attracted little scientific interest. A few years later, an Austrian, Klaproth, extracted the same element from an ore widely known as "rutile", which is a mineral consisting of titanium dioxide (one titanium atom, two oxygen atoms), that is a reddish-brown substance with a slight metallic luster. While rutile is the highest grade read the full article... Metallurgic Hardness Testing There are three types of tests used with accuracy by the metals industry,they are the Brinell hardness test, the Rockwell hardness test, and the Vickers hardness test. Hardness is the property of a metal which gives it the ability to resist being permanently deformed (bent, broken, or have its shape changed), when a load is applied. The greater the hardness of the metal, the greater resistance it has to deformation. Since the definitions of metallurgic ultimate strength and hardness are rather similar, it can generally be assumed read the full article... |
