Abstract: A vented battery cap is provided which is adapted to engage at least one of a plurality of fill holes in an automotive storage battery or similar lead acid battery and which has pressure release means for venting the combustible gases produced within that storage battery under conditions such as overcharge conditions into the atmosphere, said pressure release means comprising a plurality of extremely narrow slits having widths in the order of 0.003 to 0.005 of an inch. The remainder of the battery cap is tightly sealed to prevent any extraneous leaks of battery gases received from the automotive battery from leaking into the atmosphere. The slits are so constructed to facilitate the safe expulsion of any volume of gas normally produced by an automotive storage battery, while virtually eliminating the likelihood that ignition of gases within the atmosphere will result in explosive consequences either within the battery cap or within the battery itself.

Abstract: Heat is applied to a heat sealable material which may be in the form of a bag, for example, to seal a portion of the bag. This may be the top, bottom or side of the bag, and one form of heat sealable material is a plastic film such as polyethylene, either as a coating on the inside of a paper kraft bag or as a separate ply. The two portions to be heat sealed are juxtaposed and passed between endless metal bands which move in synchronism with the heat sealable material as a part of the conveyor means for the heat sealable material. Heat is imparted to the heat sealable material from the metal bands and it is imparted to the metal bands by electrical current conducted into the bands by collector rings on the pulleys over which the metal band is entrained. The heat is conducted through the kraft ply to the heat sealable material to cause the two portions to be sealed together.

Abstract: A feed conveyor supplies resawn split shakes of varying thicknesses to an operator at a shake panel assembling machine. The operator arranges shakes in a row with the shake butts generally aligned and the sawn surfaces of the shakes laid on the upper surface of a backing strip to which thermosetting glue has been applied. The assembly of shakes and backing strip is conveyed by a carrier belt to a press station where a solid but readily deformable elastomer pad is pressed against the rough split upper surfaces of the shakes. The pressure of the pad on the shakes causes the pad to be deformed unevenly to conform to the split surfaces of the uneven and varying thickness shakes so that each shake and all portions of each shake are held in engagement with the backing strip under substantially the same pressure while the glue is set by dielectric heating. When the glue has set, the elastomer pad is released from the shakes and the completed assembly is conveyed by the carrier belt to a discharge conveyor.
