Patent CA-1084296-A (CA)
Inventor: WILLIAMS PAUL
IPC: G01N21/00
Filed: 1979-09-25
Granted: 1980-08-26
Abstract: ABSTRACT OF THE DISCLOSURE    A property of a sheet material, such as a thin, infrared radiation-transmissive film of plastic or the like with specular surfaces is measured with substantial freedom from errors caused by wave interference effects, utilizing a radiation source for generating infrared radiation having a wavelength subject to absorption in the sheet material.  Beams of the radiation are directed from a multiplicity of points as on the diffusively reflective inner surface of a sphere to a surface of the sheet material at a broad spectrum of incidence angles.  Radiation leaving the sheet material is intercepted and redirected to a surface of the sheet material.  The radiation is directed and redirected by reflective surface elements forming an enclosing configuration which substantially confines a surface area of the sheet material.  A primary reflector is located within the enclosing configuration, and a primary beam of radiation from the source is directed onto the primary reflector so that the reflective surface elements at the beam-directing points are illuminated by infrared radiation reflected from the primary reflector.  A portion of the radiations which have left the sheet material are detected and a response indicative of the sheet property is produced as a function of the detected radiation.

Title: Carrier-supported catalyst and process  for making it
Inventor: ERPENBACH HEINZ
IPC: C07B61/00

Granted: 1982-09-07
Abstract: ABSTRACT OF THE DISCLOSURE             The invention relates to a carrier-supported catalyst comprising oxides of chromium and tungsten and at least one of the oxides of molybdenum and potassium in the atomic ra-tio of CR1W0.1-0.5Mo0-0.05K0-0.5 on a porous carrier mate-rial, and to a process for making it. To this end, the pro-cess provides a) for a dry porous carrier material to be saturated with water up to 40 to 80% of its predetermined saturation valve; b) for the carrier material treated as under a) to be im-pregnated in any sequential order, but at least once with an aqueous solution of water-soluble compounds of chromium and, if desired, potassium and sequentially, but at least once with a separately produced aqueous solution of a water-soluble compound of tungsten and, if desired, mo-lybdenum, the aqueous solutions being used in either case in a quantity which is at most necessary for complete saturation; c) for the carrier material to be dried after each impregna-tion over a period of 2 to 20 hours at 350 to 500 K, and d) for the carrier material to be sintered over a period of of 0.5 to 12 hours at 550 to 1000 K, in a stream of air. The carrier-supported catalyst finds use in the production of styrene by subjecting ethylbenzene to oxidative dehydrogena-tion with molecular oxygen in gas phase.

Abstract: TRACTOR                 Abstract of the Disclosure A tractor has a hydrostatic steering assembly 16 including a steering column 22 connected to a steering valve 18 mounted on a housing 10 for a dash.    To dampen vibrations of the steering column 22, and to prevent any excessive movement of it when a high load is applied, a support assembly 26 is provided.  This comprises a support column 28 with a bracket 30, at its upper end, which has an aperture 42 through which the steering column 22 passes.  On the underside of the bracket 30, there is a polyurethane vibration dampening insert 32 which has an aperture 46 through which the steering column 22 also passes.  The latter aperture 46 fits around the steering column 22 closely while the bracket aperture 42 is larger.    Due to the difference in the sizes of the apertures 46, 42, slight deflections of the steering column 22 will be opposed only by the insert 32, but if a high load produces a large enough deflection, the insert 32 will be so compressed that the steering column 22 will come into abutment with the bracket 30 to limit its movement.

Abstract: ABSTRACT      The liquid spray includes an oscillator for produc-ing a fan spray with liquid droplets of uniform size. The oscillator is constituted by a power nozzle. a pair of side walls forming a pair of vortice spaces offset from the power nozzle, a pair of inwardly extending pro-tuberances or deflectors downstream of which are a pair of inlets to passages leading to exits adjacent the power nozzle, and an outlet throat or aperture having a pair of short wall surfaces defining an exit throat of any value selected from about 30° to about 160° so that the fan angle can be selected to be from about 30° to 160°.  This structure results in an oscillator which has a relatively low threshold of pressure at which oscil-lations are initiated and, most importantly, the liquid is issued in a much more uniform fan pattern than here-tofore possible.  In a preferred embodiment the liquid is a windshield washer fluid and the oscillator is incorporated in a nozzle for an automobile windshield washer assembly for issuing a fan spray of washer fluid onto the windshield.
