Abstract: SLIDING DOOR WHEEL RETAINER            Abstract of the Disclosure A wheel retainer prevents a wheel of a sliding or bypass door from jumping off of the floor track on which the wheel rolls.  Means are provided on the lower portion of the retainer for slidably engaging a downwardly facing portion of the track for inhibiting upward movement of the retainer from the track.  Preferably this in the form of an L-shaped hook having a base wider than the opening of a dovetail slot in the track and a neck narrower than the opening of the slot.   The retainer can then be installed only by pivoting the retainer relative to the track for inserting  the hook.    The  retainer also has means  for engaging an upper portion of the wheel to prevent it from being lifted from the track.  The preferred embodiment is a D-shape with an arcuate portion over the top of the wheel and barbs that prevent the retainer from accidentally being dislodged from the wheel.

Granted: 1992-04-07
Abstract: ABSTRACT OF THE DISCLOSURE      An improved hemming die fixture, used in conjunction with a sheet metal press, is disclosed.  The fixture is attachable to the ram, or ram assembly, of a metal press and carries with it a hemming die.  The fixture is automatically displacable between working and standby positions.  When not in use, the hemming die fixture is placed in a standby position wherein it is placed parallel to the ram of the press, and away from a primary die on the bottom of the ram.  When required, the fixture may be actuated to place a hemming die parallel to, and below, the primary die located along the bottom of the ram.  The hemming die then coacts with the work table, or second flat hemming die, of the press to form a hem along a longitudinal edge of a piece of sheet metal in a plane other than the plane in which a full bend is first formed along the edge of the sheet metal.

Granted: 1992-09-08
Abstract: ABSTRACT         During the production of pressure moulded bodies a bonding agent that is a condensation resin with a solid resin content of at least 80% and a water content of at most 7%-wt, preferably however, of at most 5%-wt is applied in liquid or brushable form to wood chips and/or wood fibres having a moisture content of at most 10%-wt, preferably however, at most 8%-wt as starting material (this condensation resin optionally containing additives such as pigments).  The wood chips and/or fibres that have been so coated--optionally between cover layers of paper that has been impregnated with synthetic resin--are hot pressed together with the cover layers at, for example, 70 bar as the resin is hardening, so as to form a pressure moulded body.  Panel-like rough-pressed blocks can be formed from the above mentioned coated wood chips and/or fibres or alternatively, one can coat wood fibres that are already in the form of insulating panels or mats with the bonding agent.  These then form rough cast blocks or insulating panels that can be handled and transported, and which are then used as press goods for the hot-pressing process.

Granted: 1992-03-31
Abstract: ADJUSTABLE SPACERS FOR SUPPORTING                   REAR WINDOW GLASS IN AN AUTOMOBILE     ABSTRACT OF THE DISCLOSURE     A method and apparatus is disclosed for accurately positioning a window glass panel within the frame of an automobile. The method consists of placing two spacer elements on the vehicle frame and setting the window glass against a support surface formed on the spacer elements. Caulking is placed upon the automobile frame around the window opening and the window glass is placed on the caulking. The spacer elements are adjustable so as to accommodate various manufacturing tolerances and still adequately support the window glass. The spacer element disclosed by the present invention is a one-piece plastic item that can be riveted to the vehicle frame and has a top portion that is received within a bottom portion. Teeth surfaces allow incremental advancement of the top portion relative to the bottom portion. The teeth surfaces are angled with respect to the top and bottom surfaces such that the incremental advancement changes the relative vertical position of the top portion with respect to the bottom portion. The bottom portion is fixed to the vehicle frame and the top portion is advanced with respect to the bottom portion thus changing the vertical height of the support surface formed on the top portion. By accurately adjusting the position of the top portion relative to the bottom portion the support surface of the spacer element can be brought into contact with the window glass. The spacer can thus be adjusted within the automobile frame in order to account for manufacturing tolerances or the like.
