Abstract: Diphenylmethanes such as o-benzyltoluene are prepared by contacting a benzyl halide with a benzene in the presence of a catalytic amount of a normally solid, insoluble perfluorosulfonic acid polymer under reaction conditions. The o-benzyltoluenes are useful intermediates in the production of anthraquinone and anthracene.

Abstract: A firearm sighting device is described which provides a dual iron and telescopic sighting systems for the shooter. Iron sights are added to a modified telescopic sight upper mounting rings which are attached to conventional telescopic sight lower mounting rings. The modified upper rings include means for correcting for alignment, windage and trajectory. The modified upper rings also include dovetail slots, enabling various types of front and rear sight elements to be employed. For example, the rear sighting element may interchangeably be provided with a peep type sight or an open blade sight. Likewise, the front sight may include a bead or blade sighting element.

Abstract: A solid fuel burner 1 has a first chamber 2 for receiving a combustible fuel to be gasified and a substantially conical upwardly directed extraction zone connecting a bottom portion of the primary chamber 2 with a secondary chamber 8 through the apex region 42. The combustible fuel presents a relatively large surface area G into the extraction zone F and relatively low velocity gases can leave the primary combustion chamber 2 to maximize the extraction of gaseous fuel from the fuel while leaving fuel and other particulate material behind. The substantially conical shape of the extraction zone F which provides a convergent gas flow path does however enable a sufficiently high velocity or the hot gas entering into the secondary chamber 8. A transverse entry of cold air H by means of a tuyere assembly 46 is provided at the apex region 42. The high density of the cold air and its transverse flow ensures a good mixing of the cold air with the hot gas before its entry into the secondary chamber 8. The hot gas in the chamber 8 has a circular motion creating a vortex in the center of the chamber 8. Hot gas leaves the chamber 8 from one side at outlet 9 while cold air flows into the chamber 8 from an opposite side.

Abstract: A method of improving the thermal emmissivity of a cathode heater wire to allow lower temperature operation of the heater without an attendant lowering in the cathode operating temperature, in which method the surface of a tungsten or molybdenum wire is oxidized, then coated with a salt of a refractory metal, and finally heated to reduce the salt and oxide to their metallic forms thereby causing the heater wire to be roughened and darkened.
