Abstract: ORAL PRODUCT HAVING IMPROVED TASTE               Abstract of the Disclosure Oral products such as mouthwashes and dentifrices are disclosed which utilize a polyoxyethylene derivative of a fatty alcohol having 15 to 22 carbon atoms wherein the poly-oxyethylene chains are responsible for about 50 to about 90 percent of the molecular weight of the surfactant.  Un-expectedly, the nonionic surfactants solubilize peppermint oil and other flavorants at ambient temperatures and below so that the mouthwash compositions of the invention remain clear and haze-free.  The visually clear dental creams of the invention also maintain their clarity at ambient temperatures and below.          Both mouthwash and dental creams of the invention are free of the usual bitter surfactant taste.

Abstract: ABSTRACT      To measure the height of the surface of a fluent material, such as coal, in a bunker or container, pulsed radiation from a microwave source is beamed down on to said surface, and the return radiation reflected from the surface is processed to detect pulses in the waveform with time-varying amplitudes, and therefore denoting returns from the fluent material, and to reject fixed shape pulses denoting returns from the fixed structure of the bunker.  To discriminate between returns of time-varying amplitude i) from the fluent material surface and ii) from material flowing in from an in-feed, the higher frequency components, denoting the material flowing in, are filtered out.

Abstract: HIGH EFFICIENCY ORGANOSOLV              SACCHARIFICATION PROCESS          ABSTRACT OF THE DISCLOSURE         Comminuted cellulosic materials which may or may not contain lignin are partially or totally hydrolyzed or saccharified by an improved organosolv process using an aqueous acetone solvent mixture containing a small amount of an acidic compound and containing at least about 70 per cent by volume of acetone and up to virtually anhydrous acetone.  The process is performed at elevated reaction temperatures, preferably at 145°C to 230°C, for a limited period of time and then with cooling such that the resultant dissolved sugars from the hydrolysis are not degraded into non-sugars.  In particular the reaction is conducted such that the celluslosic material is dissolved and such that at least ninety percent or more of available sugars in the cellulosic material are recovered.  Unexpectedly it has been found that acetone at high concentration forms stable complexes with the sugars which prevents their degradation and also facilitates separation of the sugars.  Lignin and sugars derived are commercially useful chemical compounds.

Abstract: Abstract A weigh section of a railway track consists of two unsupported spans of conventional rail, produced by removing two adjacent supporting ties for example.  The span of the unsupported rails is approximately 64 inches, less than the minimum distance between adjacent axles of a railcar.  Four strain gauges are mounted on the under surface of the unsup-ported rail span of each rail, the four gauges consisting of two pairs of outboard and inboard gauges located in respective halves of the unsupported span.  The outputs of the four strain gauges for an unsupported span are summed by adding the outputs of the inboard gauges and substracting the outputs of the outboard gauges.  This sum produces a constant value representative of the load supported on the rail as the axle load moves between the two inboard gauges.  A limit switch tripped by a wheel of each axle activates a computer.  The computer accumulates a plurality of sum samples while an axle moves between the two inboard gauges, averages the sum samples to produce average load value for each axle of a car, and converts the accumulation of average values to the total car weight.
