Title: Particulate material loaders
Inventor: DUTSCHKE REGINALD V
IPC: B65G31/04
Filed: 1989-11-22
Abstract: ABSTRACT            This invention relates to a particulate material thrower comprising an endless belt running over a pair of rollers which provides a loading end and discharge end on the belt, and a thrower wheel running adjacent to the belt over the roller at the discharge end.  The thrower wheel is characterised by a plurality of vanes extending between the slide flanges of the thrower wheel wherein the vanes are shaped in a manner so as to collect material on the belt before throwing.  One advantage of the invention is to significantly increase the amount of acceleration that can be given to particles or other particular matter without such energy being imparted to the materials quickly or in single step so that the material such as grain is not damaged,  Another advantage of the invention is that it reduces side spillage or leakage from the belt.

Title: Process for making cubic boron nitride from coated hexagonal boron nitride and abrasive particles and articles made therefrom
Inventor: CORRIGAN FRANCIS R
IPC: C04B35/583
Filed: 1990-04-19
Abstract: Dkt. No. 60-SD-351 ABSTRACT OF THE DISCLOSURE       Abrasive particles and articles made from cubic boron nitride derived from coated hexagonal boron nitride which is substantially free of oxides and volatile contaminants.  Polycrystalline CBN is prepared from HBN by removing oxide from the surface of HBN particles to form HBN particles having a substantially oxide-free surface.  The HBN particles having a substantially oxide-free surface are coated with an agent which is capable of preventing re-oxidation of the surface of the HBN particles to form coated HBN particles in a substantially oxide-free state.  The coated HBN particles in a substantially oxide-free state are then converted to a polycrystalline CBN by direct conversion of HBN to CBN. Coating agents include metals, metals carbides, metal nitrides and metal borides.  A preferred coating agent is titanium carbide.

Abstract: A method and apparatus in a drying section of a paper making machine wherein a so-called single-wire draw is applied and wherein blow boxes (20) are used, which are intended to prevent phenomena that disturb the mutual support contact between the web (W) and the drying wire (12).  The blow boxes (20) extend across the entire width of the web (W), and they communicate with members (17, 18, 21, 22) that supply blow air, and they are provided with at least two nozzle slots (13, 14) transverse to the running and longitudinal direction of the web (W) as well as with a carrier face (16) between said nozzle slots.  Negative pressure is produced in the space (A-) defined by the carrier face (16) and the drying wire (12) by means of the ejection and prevention effects of the air jets (F1, F2) blown through the nozzle slots (13,14).  In order to speed the threading of the web (W), in the blow boxes (20) the blow sections (24 k+l...24 N) that remain outside the transverse area (A) of the leader band (R) are closed.  The blowing, which has thereby been intensified, is applied through both of the opposite nozzles (13, 14) of the blow boxes (20) in connection with the threading only within  the area (A) comprising the width (LR) of the leader band (R).

Title: Two-part captive dispersion cap device for use with a container or the like
Inventor: LEUENBERGER GERHARD
IPC: B65D51/16
Filed: 1990-08-09
Abstract: A seal is provided comprising two parts and is made of synthetic material. An upper part has an internal thread, a continuous surface area and an axial external cylinder section. A valve tube is positioned above the cylinder section and is held in place by means of a conical intermediate piece. A lower part has an external thread, a continuous surface area and an axial internal cylinder section. A sealing bulge faces the external cylinder section and a valve pin held in place above it by means of connecting bars. By turning the upper part in relation to the lower part, the upper part is displaced axially in relation to the lower part. A sealing piece is fitted axially to the upper end of the valve pin. As the seal is screwed down, the sealing piece blocks the upper opening of the upper part. Its upper end is flush with or rising above the upper part, and the valve pin is enclosed by the valve tube. When the seal is screwed down on entirely the valve pin will be located outside the valve tube. A rib at the lower part and a baffle at the upper part cooperate to limit the rotation of the upper part in relation to the lower part to less than a full revolution.
