Title: An assembly to aid painting and drawing
Inventor: CHEEVERS MARK
IPC: A47B97/00
Filed: 2010-11-18
Abstract: The present invention relates to a drawing board with additional features to enable it to be used as an aid to painting and drawing. In particular the invention has a crosspiece which slides up and down a steel rod and which can be locked onto the said rod using a knob which has a screw attached. It also has a metal or plastic strip, with two matching holes, which can be moved from side to side. The other important feature is two working surfaces with height adjustment to allow the use of paper, board or canvas. The advantage of the invention is that it breaks down the image into small parts which can be easily painted or drawn which will always be in proportion and alignment with each other ensuring better quality reproduction. <Figure 1>

Abstract: A bearing arrangement, designed in an X-configuration for a planet gear is provided with two angular roller bearings mounted a certain distance apart. Barrel-shaped needles have a large radius of curvature and their length is considerably greater than their diameter. Raceways of the two angular roller bearings have a circular curvature, center of which is located in the radial direction, outside the raceway diameter and in the axial direction, between inner lateral surface and axial center of angular roller bearing in question. As a result, the bearing arrangement is able to pivot slightly even though its dimensions are very small and can also absorb axial loads.

Title: Method of inspection of magnetic properties of ferromagnetic powder
IPC: G01N27/72
Filed: 1981-02-20
Abstract: The invention relates to a method permitting the magnetic properties of ferromagnetic powders which are used for the preparation of heavy media for the float-sink dressing of minerals, to be tested. To this end, the invention provides for the ferromagnetic powder to be magnetized in a magnetic steady field at a field strength within the range 600 to 1000 amperes per cm and the magnetized ferromagnetic powder to be demagnetized in a cyclicly decreasing magnetic alternating field at a field strength within the range 1000 to 1500 amperes per cm. Next, the ferromagnetic powder so pretreated is heaped up, in the center portion of a circular plate made from dielectric material and the circular plate is placed on an iron core-provided coil. An alternating current voltage of 180 to 260 volts is applied to the coil, thereby effecting the occurrence of alternating fields of 180 to 220 amperes per cm in the center portion of the circular plate. The ferromagnetic powder heaped up is observed for the figure it is forming under the influence of the alternating fields. The formation of a closed figure around the center portion of the plate indicates unlimited qualification of the ferromagnetic powder for use in a heavy medium suspension.
