Abstract: DECUBITUS PAD     Abstract of the Disclosure A protective pad adapted for being positioned on an elbow or heel of a bedridden patient for protecting against the development of bedsores.  The pad includes a scoop-shaped body member of cushioning material having a concave inner surface thereon defining an elbow or heel receiving pocket, a pair of straps extending in spaced apart relation from a rear portion of the body member and being of a length sufficient to permit positioning the straps across the body member for overlyingly engaging the limb of a patient, and a pair of fasteners carried by a front portion of the body member for releasably securing an end portion of each strap to the front portion of the body member.  The fasteners are positioned in spaced apart relation on the body member and are adapted for securing the straps in overlapping crossed relation overlying the limb of the patient whereby the straps facilitate maintaining the body member in conforming relation on the limb of the patient while allowing free movement of the limb and while avoiding constriction of the limb as would reduce blood circulation therein.

Abstract: COIL TERMINAL SUPPORTING BOARD   FOR DYNAMOELECTRIC MACHINE            Abstract of the Disclosure A terminal board is provided for terminating the coil ends of a winding of an electric motor or other device.  In a preferred embodiment, the terminal board includes multiple groups of terminals joined together by a wing member.  The ter-minal board is first retained in position by press fitting a boss on the terminal board into a mating hole in the supporting structure and subsequently the coils are wound.  The coils co-operate with a portion of the terminal board to provide a second means to retain it in position.  The wing members provide a barrier to retain the individual windings of the coils.  The be-ginning, end, and taps, if used, of each coil are laid in indi-vidual slots on the terminal board to retain the coil ends.  The slots in the terminal board lead into a well in the terminal board into which a terminal is inserted.  The terminal includes slots which are sized to engage the ends of the coil windings, pierce the insulation and provide mechanical and electrical connection to the wires.  An anvil within the well helps retain the wire during terminal insertion.  The terminal is adapted to make connection to an external wire which may be inserted into the terminal in the same direction that the terminal was inserted in the well The terminals of the terminal board may be adapted to make con-nections with projections from another terminal board which may overlay the first terminal board and may include a brush assembly. At a subsequent stage of assembly, the boss on the terminal board may be knocked off.

Abstract: ABSTRACT OF THE DISCLOSURE             Apparatus for transferring articles (such as two-piece cans) between work stations, at succeeding ones of which a dimension (such as a diameter) of the articles is reduced.    The articles pass along a channel, and at each station means are provided to stop the articles in position to be operated upon.  After the completion of an operation which reduces the dimension of the article, the article may pass the stop means, and be transported to the next station, where other stop means are provided to position the article for the next operation.          The articles are conveyed along the channel by aerodynamic or other means.  Each of the stop means is shaped to fit the article which is stopped by it, and vacuum means are associated with  the stop means to insure accurate positioning of the articles at each station for the operation to be performed on them at that station.

Abstract: ABSTRACT:                The invention relates to a method of manu-facturing a cathode-ray tube for displaying coloured pictures. Said method comprises an exposure step in which the exposure is carried out by means of an elongate light source via a shadow mask having elongate apertures the longitudinal axes of which extend parallel to the longi-tudinal axis of the light source. By moving the light source uniformly during the exposure over a distance substantially equal to an integer number of times the length of the light source in the direction of the longitudinal axis, a line structure is obtained on the display screen in which the width of the lines is very homogeneous.
