Abstract: The present invention relates to methods and agents for preventing the staining of teeth caused by the nonenzymatic browning of proteins in the oral cavity. Both oral and parenteral administration ft the agents are disclosed. Suitable agents for the inhibition of nonenzymatic browning may be formulated as rinses and toothpastes, and include compounds capable of reacting with the carbonyl moiety of the early glycosylation product resulting from the initial reaction of a target protein in the nonenzymatic browning reaction. Preferred agents are those having an active nitrogen-containing substituent, as well as amino acids, their esters and amides. These preparations may further include known anti-plaque agents such as chlorhexidine.

Abstract: The direct acting air brake for railway vehicles comprises a time controlled driver brake valve 12, a relay valve 7 controlled by this and brake cylinders 19, the pressure applied to which by the relay valve 7 via pipelines 14, 17 being monitored. The brake pressure prevailing in the brake cylinders 19 is displayed by a pressure gauge 22. In order to prevent trailing or lagging of the brake pressure prevailing in the brake cylinders 19 after completion of an actuation of the driver brake valve 12, an air reservoir 24 is connected to the control inlet 6 of the relay valve 7 via a nozzle 23. The nozzle 23 and the air reservoir 24 are matched to the flow resistances in the pipelines between the relay valve 7 and the brake cylinders 19 in such a way that on completion of an actuation of the driver brake valve 12 they generate an equalisation pressure on the control inlet 6 which corresponds to the instantaneous brake pressure prevailing in the brake cylinders 19 at the end of actuation. The air brake facilitates simple and precise control of specific brake pressures to be observed by means of the pressure gauge 22. <IMAGE>

Title: Gas detecting device
Inventor: YASUNAGA SUSUMU
IPC: B60H3/00

Abstract: When the output of a gas sensor is approximately constant, the sensor output is stored as a reference output. Evolution of a gas is detected from variations in the sensor output from the stored reference output. The sensor output which is constant is detected by establishing that the difference between a maximum and a minimum of sensor output in a predetermined section is not greater than a specified value.

Abstract: Sounds are caused to be generated in sequential order in sound-generating units in an electronic musical instrument system, for instance, a keyboard, an electronic drum apparatus, a rhythm machine or an automatic performing or accompanying apparatus. Consecutive note-one messages are processed to superpose such musical tones as generated by the same notes identified by said messages. A well balanced generation of sounds between the units (5) which generate sounds in circulative sequence based on performance-controlling messages received by said units (5) is enabled according to preferential orders, as well as a good reproduction of changes in generated volume of composite musical tones due to attenuation thereof caused by a new note-on message which alters the generated volume of the musical tone which is being generated by a previous note-on message.

Abstract: A low-water-pressure-controlled hydrologic test uses a measurement pipe (1) containing an inner packer (3) which is equipped with a water pressure gauge (4) at its tip. Some water is poured into the measurement pipe (1) in advance so as to diminish the pressure head difference between the in-pipe pressure and the pore water pressure of the rock concerned. The coefficient of permeability is obtained by measuring changes in the recovered water level in terms of pressure changes. In the case of an aquiclude, the inner pressure is raised by expanding the inner packer (3), the coefficient of permeability being obtained by detecting the changes in inner pressure. Thus, the method allows a permeability test to be conducted continuously at various depths. In addition, it helps to shorten the measurement time to a remarkable extent and enables the rock condition to be investigated without departing from the natural condition.

Abstract: A rear wheel steering system is disposed in a rear wheel steering mechanism (B) and has a power cylinder (13) for generating a power for steering the rear wheels (2L,2R) in response to a liquid pressure. The power cylinder (13) is connected to a pump (20) as a source of generating the liquid pressure through a high pressure passage (18) and further to a reservoir tank (17) through a low pressure passage (19). The high pressure passage is connected to the low pressure passage through a relief passage on the pump side and a relief passage on the power cylinder side, the relief passages being disposed in parallel to each other. The rear wheel steering system is provided with a passage shifting system (H) for closing the relief passages during stationary period of time while opening each of the relief passages during operation and dividing the high pressure passage between the relief passages into sections and with a narrowed passage portion disposed at the relief passage on the power cylinder side. Operation of the passage shifting system independently allows the high pressure passage on the pump side and the high pressure passage on the power cylinder side to be communicated with the low pressure passage. At this time, the liquid pressure from the power cylinder is gradually released by the action of the narrowed passage portion. The liquid pressure withdrawn from the pump is rapidly released to the low pressure passage without interference with the narrowed passage portion.

Abstract: A method of quantitative analysis of solids carrying drilling mud and removed from a drilling fluid circulating in a wellbore being drilled is described. The method comprises the steps of: sampling the removed solids, and analysing the sample to determine the density of the solids and their weight fraction, drying a known weight of the sample to constant weight so as to obtain the solids in the form of dry solids, and analysis of the latter by an infrared spectroscopy technique. The concentration of the substances in the removed solids is then determined. The method can be applied to the control of the drilling operation by monitoring the quantity of products added to the drilling fluid, such as barite and polymers or a product coming from the borehole wall or the underground formation being drilled. The invention also applies to the control of the working condition of the mud solids equipment.
