Abstract: ABSTRACT OF THE DISCLOSURE Weather resistant boards (for instance, particle boards, facade covering boards, and wall elements) and mouldings (for instance, containers, vessels, prefabricated building elements, and roof elements) of resin-impreg-nated wood fibres and/or other particle materials are provided herein.  In the manufacturing process, the base fibres are coated with a solidly ad-hering outer coating of a vulcanizable weather-resistant rubber, or other elastomer, suitable for vulcanizing, without the addition of any adhesive binding medium.  The process for the production applies the principle that the condensation of the adhesive agents in the laid-down batt of the fibre-particle mixture on at least one side of that batt as well as the vulcan-ization of the coating material are performed simultaneously, under the same physical conditions (pressure, temperature, time).  By using the usual hot pressing machines, weather-resistant boards and mouldings can be produced in one single production run.  The final product is an integral united material, in which the base and the coating material are impregnated one into the other within a facing area.

Abstract: FLOW RATE SENSOR            ABSTRACT OF THE DISCLOSURE           A flowmeter for measuring the flow rate of fluids, having a range from a very low to a very high value.  An impeller is located in a pipe for rotation with the flow of fluid.  Metallic vanes of the impeller pass through the field of an inductor which is in a series circuit with a capacitor.          An oscillator applies a signal at the series resonant frequency of the capacitor and inductor.  The envelope of the resulting high voltage signal across the inductor is detected, filtered, and the resulting output pulses in excess of a minimum threshold can be applied to a counting apparatus for establishing the flow rate with high sensitivity.  Since the spacing between the impeller and pickup is not critical, a meter is provided which does not clog with magnetic or non magnetic particles suspended in the fluid to be measured.  The meter pickup can also be used to sense the rotation rate of wheels or the like having metallic discontinuities, whereby the speed of a vehicle, the rotation rate of a shaft, etc. can be determined.

Abstract: ABSTRACT:            The invention relates to a discharge lamp which has a discharge vessel provided with an external auxil-iary electrode.  The lamp also has a bimetallic strip which in the inoperative condition of the lamp causes the external auxiliary electrode to bear against the dis-charge vessel.  According to the invention the auxiliary electrode is connected to an end of only one bimetallic strip and in the operating condition of the lamp the auxiliary electrode is remote for the greater part from the discharge vessel due to the action of bimetallic strip.  As a result of this it is achieved in a simple manner that an auxiliary electrode stimulating the igni-tion is combined with an operating condition of the lamp in which no hindrance is experienced from the auxiliary electrode.

Abstract: Case 3409 TEMPERATURE-RESPONSIVE ELECTRICAL SWITCH                  WITH SLIDING CONTACT            Abstract of the Disclosure A temperature-responsive electrical switch is provided which has a pair of axial leads, one of which is connected to the cylindrically-shaped electrically conductive housing, and the other of which passes through an insulator into the interior of the housing. A cylindrical-shaped, slideable electrical contact which is open at one end is positioned in the housing. A coil spring is located inside the slideable contact between the bottom end of the contact and an enlarged section of the insulator. The contact has a plurality of spring fingers which are integrally formed from the bottom of the contact and which project upwardly from the bottom of the contact toward the head of the insulated lead. A thermally-sensitive pellet, which melts at a predetermined temperature and is formed to have a cavity in it, is positioned below the spring fingers. The pellet is dimensioned transversely so as to force the fingers into contact with the head of the insulated lead. Upon reaching the predetermined temperature the pellet melts and its liquid mass assumes a smaller transverse dimension, because of the original cavity in the solid pellet. This allows the spring to release its compressive force; and this, in turn, allows the slideable contact to move along the interior of the housing so as to thereby break electrical contact between the spring fingers and the head of the insulated lead.

Abstract: Abstract of the Disclosure A mixture of brominated oligomeric polystyrenes, having a degree of polymerization of from 3 to 400, and low molecular weight brominated aromatic compounds of the diphenyl ether type is obtained by polymerizing the non-brominated starting materials, in a halohydrocarbon solvent, using a Lewis acid catalyst.  The reaction mixture is then brominated and extracted with water to remove hydrogen bromide and catalyst, and the solvent and volatile con-stituents are separated from the product.  The bromination is carried out at from -30°C to +130°C.  The mixtures of brominated oligomeric polystyrenes and brominated aromatic compounds have a low melt viscosity and are therefore particularly suitable for incorporation, as a flame-proofing agent, into thermoplastics.
