Abstract: A filter gauge comprising a piston operable in a pressurized cylinder, the piston having a rod which projects from the cylinder, and grippers mounted within the cylinder and accommodating movement of the piston and rod having indicia indicating the lowest pressure reached in the cylinder as a water conduit to which the cylinder is connected is being drained. The grippers prevent the rod from moving in the opposite or extending direction as the cylinder is being pressured gradually by the water seeping through the filter and equalizing the pressure at both sides thereof.

Abstract: A compact two-sided cooking device is disclosed for use with an existing grill to permit two-sided cooking of food products, such as hamburger patties, on a relatively limited basis. The device includes a cooking assembly having an electrically-powered cooking platen which can be selectively positioned on food products on the grill for effecting accelerated two-sided cooking thereof. The present cooking device has been particularly configured for use in conjunction with, and for rocking movement on, a commercially-sized restaurant grill, and provides greatly reduced cooking times so that a customer's order can be freshly and efficiently prepared even during relatively slow business hours.

Abstract: An apparatus for preparing scrambled eggs on a grill surface, wherein liquid scrambled eggs mix are placed within egg rings, each having a lower edge portion in intimate contact with a heated grill surface, and the egg rings are moved repeatedly to and fro, preferably in a reciprocating motion, while maintaining the lower edge portions of the egg ring in intimate contact with the grill surface. The egg mix is rapidly moved within the confines of the egg rings, and that rapid movement is continued until the egg mix in each ring has congealed into a mass of cooked scrambled egg. A carriage mounts at least two such egg rings, and each egg ring mounts a comb-like interceptor member which engages, moves, and mixes the eggs in the egg ring as the egg ring moves to and fro. The to and fro movement which is preferably reciprocating movement, is such that it produces a wave-like motion of the liquid eggs during a first portion of the cycle of rapid movement of the eggs in the egg ring.

The egg mix is rapidly moved within the confines of the egg ring, and that rapid movement is continued until the egg mix has congealed into a mass of cooked scrambled egg. Desirably a carriage mounts a plurality of egg rings, and each mounts a comb-like member which engages, moves, and mixes the eggs in the egg ring as the egg ring moves to and fro. The to and fro movement is such that it produces a wave-like motion of the liquid eggs during a first portion of the cycle of rapid movement of the eggs.
