Abstract: A conventional motorhome can be improved by using joists to elevate the floor of the living area of the motorhome to the level of the floor in the driver's compartment in the motorhome. Preferably tanks as are required in connection with the motorhome are located in spaces between the joists.

Abstract: When a comparatively large amount of material must be located on the label for a comparatively small container such as a bottle it is desirable to form the label so that a first portion of it can be wrapped around and adhesively secured to the exterior of the container and so that a second portion can be wrapped around and adhered to the exposed surface of the first portion. The adhesive used in adhering the second portion to the first has less adhesion than that used to hold the first portion to the container. This is preferably achieved by overprinting an adhesive coating on the second portion with a non-adhesive material.

Abstract: A desirable travel trailer can be constructed so that the internal floor within such a trailer is capped by a series of joists located on the chassis of the trailer. The spaces between the joists can be used to hold various tanks and other items assocated with the use of the trailer. Preferably the tanks which are expected to be heaviest as the trailer is used are located directly above the undercarriage of the trailer so that the tongue weight of the trailer is not altered or significantly altered as the weight of such tanks are changed due to changes in their contents.

Abstract: The removal of particulate matter from a gas stream through the use of a separator in which the weight of the particulate matter aids in its separation can be improved by wetting the particulate matter. Preferably the gas stream is caused to flow under turbulent conditions through a restricted portion of the apparatus used while streams of water are directed into the gas mixture being treated.

Abstract: A swimming pool vacuum apparatus as described in the U.S. Pat. No. 3,443,264 can be improved by providing a plate holding an outlet nipple from the container of such an apparatus on the bottom of the container so that the position of the outlet nipple can be varied or changed by changing the position of the plate. The lid in such an apparatus is improved through the use of a peripheral groove on the lid facing the top of the container containing an O-ring which fits against the container so as to form a seal with it. Preferably spacers are provided limiting the amount that the O-ring can be compressed and holding the O-ring within the groove.

Abstract: Desirable casters can be formed by using two separate, interfitting housing members to create the yoke of a caster. As these housing members are assembled they come together so as to hold the wheel of the caster generally between arms of the yoke (which are formed on the housing members) and so as to hold a shaft used in mounting the caster. Fasteners are provided so as to hold the housing members together in an operative configuration.

Abstract: A distribution fitting primarily useful in connection with drip or seep irrigation can be constructed so as to utilize a series of ports defined by circular holes located immediately adjacent to one another around a spherical wall, each of the ports being constructed so to serve as a compression fitting.

Abstract: A signboard of a type used to carry replaceable letters or similar indicia can be improved by using at least one easily operated holder to connect the signboard to a support such as a wall. This permits the signboard to be easily removed from the support so that it can be held in a convenient manner as the content of a sign on the signboard is changed or altered.

Abstract: The strength of a bead containing microbial cells within a retaining permeable membrane is improved by incorporating finely divided sericitic clay particles within a hydrocolloid-containing composition used to form the membrane. The hydrocolloid is preferably alginic acid, carboxymethyl cellulose, methylethylcellulose or polyvinyl alcohol in an amount of about 10 to 40% by weight.

Abstract: An adsorbent, absorbent product can be produced from sericitic clays by removing alumina values from such clays with a mineral acid, removing oil contaminants from such clay with a solvent or solvent mixture and removing amorphous silica from them with a caustic solution. The particles of the clay are dried after treatment in these manners. They are then ready to use.

Abstract: A collapsible container primarily useful as a wastebasket can be constructed utilizing a flexible, tubular vertically oriented peripheral wall reinforced by vertically extending stiffeners and a rigid bottom fitting within the peripheral wall in order to hold it in a normal open configuration. The bottom wall is capable of being positioned in and of being removed from the peripheral wall. In the absence of the bottom wall in the peripheral wall the peripheral wall may be collapsed.

Abstract: A desirable electric water heater can be constructed by providing a housing containing three separate heating elements. These heating elements are connected in series with separate switches which are ganged together so as to be closed when there is a pressure drop in the housing and so as to be opened when the pressure in the housing increases. The heating elements and their associated switches are in parallel across a power supply line.

Abstract: A reel cover which is primarily intended to be used in enclosing the space between the sides of a reel can be constructed from a single extruded strip of a polymer such as plasticized polyvinyl chloride. Such a strip as formed will have parallel ridges on its under surface which are adapted to fit against the sides of the reel. The cover is formed from the extruded strip by punching out openings in terminal portions in the ends of the strip so that portions of the ridges remain on these terminal portions. The openings and the remaining ridges are dimensioned so that one terminal portion may be placed over the other and the two terminal portions can then be attached by pushing the remaining ridges on one terminal portion through the openings on the other terminal portion.
