PURPOSE:To ensure a stable speed change operation by enabling pressurized oil to be preferentially supplied to hydraulic cylinder and hydraulic clutch sides for traveling speed change when the hydraulic cylinder and clutch for the travel ing speed change and a hydraulic clutch of PTO system are operated by a single pump. CONSTITUTION:A transmission system of an agricultural tractor transmits the p...

Percentage concentrations of constituents of a sample of cereal grain or other agricultural product in a flowing stream are determined while harvesting or processing using a short wave near infrared analyzer. The analyzer irradiates the sample, picks up diffuse reflectance of individual wavelengths from the sample and spatially separates the diffuse reflectance into a response at individual wavele...

A method of making lead-acid batteries uses a container standardized for a twelve-volt battery and dual flag straps in the inner cells so that batteries with voltages of two, four, six, or twelve can be preselected as desired, the more preferred embodiments having one terminal cell with either two terminal bases or dual flags so as to minimize the assembly equipment required.

A method of producing a high-density article is presented comprising selecting one or more primary tungsten-containing constituents with densities greater than 10.0 g/cc and one or more secondary constituents with densities less than 10.0 g/cc, co-milling the mixture of constituents in a high-energy mill to obtain mechanical alloying effects, then processing the resulting powder product by convent...

A recorded data reader is provided having a light source for emission of a beam of light to a recording medium and a photosensitive means. A polarized beam splitter incorporate an interface developed between a titanium diffused layer and a proton exchanged layer formed by treating one region of the titanium diffused layer for proton exchange, both arranged on the substrate of lithium niobate mater...

PROBLEM TO BE SOLVED: To easily adjust the position of a flange guide roll accompanied by the change in the flange width, the wear of the flange guide roll, and the reform-cutting of a web supporting roll without changing the roll, to increase the range of the positional adjustment of the flange guide roll, and to simultaneously guide and support a web and a flange by one supporting device in a ma...

PURPOSE:To prevent metallic foreign matters, iron powders and others from depositing on a filter without restricting materials for an oil pan and others and by effectively removing those metallic foreign matters, iron powders and others. CONSTITUTION:On an inlet port part of a strainer, a ring magnet 50 is made contact with a positioner 52 and fit in the head end of a strainer body 21. The positio...

A method for the preparation of cellular polymeric products which comprises reacting an organic polyisocyanate with an isocyanate-reactive composition, characterised in that the isocyanate-reactive composition comprises a blowing promoter which is a cyclic urea compound having at least one isocyanate-reactive substituent.
