Abstract: A moisture guard for inhibiting water damage to the interior of a home or building caused by moisture, leaks, rain, snow or the like accumulating at a door frame, window frame or the like. The moisture guard comprises a metallic facing fixed to a plastic molding, such as ABS plastic. The sill of a window frame or the sill of a door frame is seated on the metallic facing. The moisture guard has a z-shaped cross-sectional area. An integrally formed upstanding rear flange is at the rear edge of the base and an integrally formed depending front flange is at the forward edge of the base. At an end of the base is formed an end flange with an upstanding vertical wall and with a vertical side wall. The height of the vertical side wall is coextensive with the height of the upstanding end wall and the vertical side wall extends to the depth of the depending front flange.

Abstract: Live Sendai viruses are modified in fertile chicken egg embryos to be administered as a vaccine through an aerosol for the immunization of animals against Sendai disease. The live Sendai viruses are diluted by at least thirty-one passages in fertile chicken egg embryos. Twenty passages are at a lower than normal incubation temperature and the remaining passages are at the normal incubation temperature.

Abstract: A bulk material container comprising a shell made from suitable material, such as aluminum or stainless steel. Disposed within the shell is a floatable rigid follower. The vertical position of the floatable rigid follower varies with the level of flowable bulk material stored in the shell. The rigid follower comprises axially aligned, juxtaposed rigid sections with a flexible wiper secured therebetween. A permanent magnet is carried by the rigid follower for movement therewith and means responsive to a magnetic field are attached to the exterior of the shell to detect the height of the permanent magnet. Indicating means are responsive to the operation of the means responsive to a magnetic field for indicating the level of the rigid follower. In a modification of the bulk material container, the wiper is replaced by an inflatable seal and the floatable rigid follower provides a selectively positionable cover for the bulk material container.

Abstract: A prefabricated panel for use in constructing a roof or a wall surface has the appearance of a shingled surface on which shingles have been positioned and secured one by one. The panel may be formed in one piece or it may consist solely of shingles and transverse mounting strips so oriented and secured together that the panel has an exceptional ability to resist loads. Whether made in one piece or from a plurality of members, the panel is arranged so that any one of a plurality of cuts can be made in the panel without destroying the integrity or usability of either of the several parts of the panel.

Abstract: A stove includes a housing having side-by-side chambers each of which may be alternately used either as a firebox or an oven. One chamber is located directly under a grill while the other chamber is located under a griddle so that the location of the fire can be selected to obtain the most advantageous heat-distribution for the type of cooking engaged in--but the arrangement is such that no matter which firebox location is selected, both the grill and the griddle are heated to some extent.

Abstract: A single acting steam engine wherein means are provided for auxiliary exhaust through the piston when an auxiliary exhaust poppet valve is open and the auxiliary exchange passages of the piston register with exhaust ports in the cylinder wall. The opening and closing of the auxiliary exhaust poppet valve are responsive to the rate of reciprocation of the pistons. A multiple of said engines may be utilized in combination to provide a multiple cylinder power plant. The engines drive a swash plate, which is formed with recessed, annular thrust surfaces. Projecting at right angles from the recessed, thrust surfaces are exhaust cams that engage valve stems through cam followers for actuating the same. The valve stems actuate the exhaust valves. The throat thickness of the swash plate between the recessed annular thrust surfaces is of uniform dimension along the circumferential paths thereof.

Abstract: A bulk material container comprises a shell made from suitable material, such as aluminum or stainless steel. Disposed within the shell is a follower. The vertical position of the follower varies with the level of flowable bulk material stored in the shell. A permanent magnet is carried by the follower for movement therewith and a magnetic switch operatively responsive to the magnetic field created by the permanent magnet is attached to the exterior of the shell to detect the height of the permanent magnet. A level indicator is responsive to the operation of the magnetic switch for indicating the level of the follower.

The cover is releasably secured to the top of the oven and the folded truncated pyramidal firebox, the folded truncated pyramidal support member, the diffuser, the grill, the griddle and the windbreak are retained therebetween in a compact form. In use, the oven with the drawer may be employed as the base of the cooking unit or, in the alternative, the oven may be disposed above the extended truncated pyramidal firebox, the extended truncated pyramidal support member and the diffuser. In the alternate arrangement, the cover serves as the base for the cooking unit.
