Title: Tensioner for belt and chain drives
Inventor: STARK HANS JURGEN
IPC: F16H7/12
Filed: 1986-07-12
Granted: 1989-08-17
Abstract: A belt or chain tension producing apparatus comprises a tension head engageable with a chain, belt or the like of a chain or belt drive and a tension piston on which the tension head is carried. The tension piston is guided longitudinally slidable in a guide body which is simultaneously a mounting element and is acted on by at least one tension spring engaged with it which is supported at its other end on the base of the guide body. In order to provide a particularly compact structure and thus also a more universal structure, at least a part of one side of the tension piston projects laterally from the guide body and the tension head is mounted laterally on a mounting surface on that projecting part. A recess may be provided in the tension head to better mount it on the tension piston.

Abstract: A method is disclosed for producing ammonium metatungstate from ammonium paratungstate. The method involves first roasting the ammonium paratungstate at from about 275 DEG  C. to about 300 DEG  C. for from about 10 hours to about 20 hours to remove some ammonia and some water. The roasted ammonium paratungstate is then added to dilute solution of an ammonium metatungstate which is at a pH of from about 3.6 to about 4.2, the rate of addition being such that a slurry is produced having a pH of from about 3.6 to about 4.2. The pH of the resulting slurry is then adjusted to stabilize it at from about 3.6 to about 4.2 followed by evaporation to form a relatively concentrated solution of ammonium metatungstate which is then separated from any insolubles. Ammonium metatungstate is then crystallized from the relatively concentrated ammonium metatungstate solution.

Abstract: Novel compositions of matter include: mixed oxides of (a) at least one oxide of chromium, at least one oxide of manganese and at least one oxide of magnesium, Lanthanum Series metals, preferably lanthanum and cerium, and/or niobium; (b) at least one oxide of chromium, at least one oxide of calcium, strontium, tin and/or antimony, at least one oxide of manganese and at least one oxide of magnesium, Lanthanum Series metals and/or niobium; - (c) at least one oxide of chromium, at least one oxide of iron and at least one oxide of magnesium, , Lanthanum Series metals and/or niobium; and (d) at least one oxide of chromium, at least one oxide of liron, at least one oxide of manganese and at least one oxide of magnesium, Lanthanum Series metals and/or niobium. These compositions are particularly effective as catalyst compositions for the conversion of C, and C, hydrocarbons to less saturated hydrocarbons, with high selectivities to ethylene and ethane and particularly ethylene, and the addition of the chromium significantly extends the activity of the catalyst for such selective conversion before regeneration is necessary. A method of converting C, and C, hydrocarbons to less saturated hydrocarbons, and selectively to ethylene and ethane and particularly ethylene, is also disclosed. Carrying out the process in the presence of steam is essential to the process when the catalyst contains iron and is optional when the catalyst does not contain iron. Limiting the amount of bound or fixed sulfur in the catalyst also improves the catalyst.

Abstract: The invention relates to an aqueous ink for writing, drawing, or marking, which has as a dispersion stabilizer a degradation product of gelatin made by enzymatic action of a protease. The process of the invention is carried out by subjecting an aqueous gelatin solution to degradation by an enzyme, then inhibiting the enzyme, such as by heating to 90 degrees C. or above, before the degradation has proceeded to products which no longer have activity as dispersion stabilizers. Subsequently, colorants such as pigments can be added along with other desired additives.

Abstract: The invention relates to a buffer gear for rail vehicles comprising two telescopically nesting countersprung housing sections (buffer sleeve 1 and buffer ram 2) and in the sleeve buffer a pressure cylinder (3), supported at one end against a housing section, with a plunger (4) protruding from the other end of the pressure cylinder (3) and supported against the other housing section, which plunger at its end extending into the cylinder carries a plunger head (4b), the pressure cylinder (3) being filled with a compressible elastomer (20). The object of the invention is to design the buffer gear so that its energy absorption can be accurately gauged by simple means, the static characteristic of which is insensitive and durable even under extreme stresses by virtue of suitably designed components, which can be built into any existing buffer. This object is achieved in that the pressure cylinder (3) has two elastomer chambers (15) and (16) separated by a guide ring (17) containing apertures, the cross section of a first elastomer chamber (15) receiving the plunger head (4b) matching the plunger head (4b) with a predefined degree of play and the second elastomer chamber (16) having a larger diameter. <IMAGE>

Abstract: A coating composition is now provided which can have a great number of desirable coating characteristics, when the composition is applied and cured on a metal substrate. Moreover, the coating composition has applicability to a great variety of metal substrates. Such substrates include base metal such as steel as well as metal coated substrates such as zinc electroplated steel. Furthermore, the coating compositions can be useful when applied to substrates sensitive to elevated cure temperature, e.g., annealed steel. In one important aspect the composition can contain hexavalent-chromium-providing substance in mixture with cobalt compound. Particulate metal may be present in the compositon. A composition furthermore most desirably contains a special organic acid/alcohol reducing agent combination for the hexavalent chromium. The composition can provide a low-cure coating on a metal substrate, which can then translate into higher production line speeds as when used for coating of metal coils.
