Abstract: Round Table is a game table on which games can be played utilizing standard table tennis balls and paddles. The playing surface is flat and of circular shape. The playing surface can be divided into 2, 3, or 4 equal sections by dividers which radiate from the center of the playing surface. The dividers can be attached to one another by clips which fit over the top edge of the dividers. When the table is divided into 2 equal sections supports which attach to the bottom edge of the dividers can be used to hold the dividers upright. An optional post can be placed at the center of the playing surface and used for screening and deflecting shots. The hollow post would have 4 slots on one end and 3 on the other enabling the post to be slipped over the dividers at the center of the playing surface.

Abstract: A chain lock for sliding doors which consist of two or more vertical panels horizontally relatively slidable in a frame either into essentially edge to edge relation to cover the frame, or into overlapping relation to open the door, only one of the panels being movable and the others fixed, the lock consisting of a short length of chain adapted to be extended horizontally between the slidable panel and either a fixed panel or the door frame, one end of the chain being securely affixed and the other end being detachably connected to permit movement of the slidable panel.

Abstract: A lock protector for wooden doors equipped with both the usual bolt or latch lock and the common safety chain, consisting of a strong metal door plate of U-form adapted to bridge the free edge portion of a door at the lock and apertured to pass the lock bolt, and a chain plate adapted to be strongly affixed to the door frame, the safety chain being permanently affixed to the door plate and detachably connected to the chain plate. Strong affixation of the plates to the door and door frame resists tearing out the chain connections by kicks, blows, or pressure applied to the door, and the form of the door plate offers similar protection to the bolt assembly. Additionally, the chain plate is specially formed to prevent the common type of break-in known as "credit card" entry.
