Abstract: An artist's medium comprising a rigid backing of non-planar surface, an artist's worksheet and a means for securing the sheet flush to the surface of the backing so that the artist's worksheet has the non-planar contour of the surface of the backing. This medium permits an artist to produce a painting or form of art work on a working surface, portions of which have a different spatial relation, depthwise, with other portions thereof.

Abstract: An adjustable strike for a latch bolt of a swinging door, the strike having a face plate to be placed over an appropriate cavity and having a lip to extend into the doorway to engage and to press the latch bolt as the door closes. A flange is secured normal to the plate to extend into or beside the cavity between the plate opening and the lip. A bolt extends through the flange, preferably being threaded therethrough. A movable wall, parallel to that flange and spaced therefrom is secured to the end of the bolt and situated within the cavity behind the face plate, to be positioned within the plate opening so that the keeper surface of the latch bolt will bear against this wall when the door is closed. Longitudinal movement of the bolt and the flange causes the wall to move towards or away from the flange, thereby altering the distance between the door stop and the movable wall. The wall is moved to a distance which will provide a secure fit of the latch bolt and minimize rattling of the closed door.
