Abstract: A trowel suitable for spreading underlayment onto a floor and for later spreading an adhesive layer over the hardened underlayment. It makes use of a rail on one side of which the handle is mounted and on the other side of which the blade is mounted. The blade is of a spring metal, and the rail is in the form of a U-shaped channel member secured to the central portion of the blade. The rail is wider than the handle, and covers about 87% of the length and about 60% of the width of the blade, to stiffen the blade while leaving its edges somewhat flexible. The rail is also provided with flange on each side of the channel portion, and the flanges each contain openings for receiving spring clips bent up from the blade, so that the blade can be easily mounted to and demounted from the rail. Punched-up detents on the blade cooperate with bent-down ends of the channel to hold the blade in position on the rail while permitting its easy release for cleaning or replacement.

Abstract: The invention provides cereal snackfoods of the expanded variety such as crisps and the like. The snackfoods of the invention comprise discrete cooked portions of a dough composition comprising gelatinized starch and added cereal bran other than rice bran, in which the amylolytic activity of the bran is controlled, and contain at least about 5% by weight and generally no more than about 35% by weight of oil or fat. The snackfoods may be produced from a half product comprising at least some gelatinized starch and added cereal bran by frying or by immersion in a bed of hot particulate material followed by spraying with fat or oil. Even when fried the snackfoods have a lower energy value than comparable known products; moreover they are highly palatable, and the bran content provides a useful source of fibre in any diet.

Abstract: A printer stand comprises a support base for holding a rear-ejection printer and a paper catcher mounted to the rear of said printer and extending rearwardly and upwardly therefrom. The catcher comprises a flat backer panel having bent-up side flanges and having a bent-up lower ledge for supporting the lower edge of a packet of sheets of paper resting against the backer panel. The catcher is mounted to the base for easy removal by providing a forwardly and downwardly extending slot at the rear of each side wall of the support base, into and out of which the panel can readily be slid; the side flanges are preferably spaced apart by only slightly more than the distance between the outer sides of the side walls, and the ledge is preferably at about right angles to the packer panel. The system provides stable support of the packet of sheets, is easily assembled and disassembled, and is inexpensively made from a single metal sheet by bending up the side flanges and the ledge.

Abstract: A coating composition comprising a major amount of resin and a minor amount of a property-improving additive,said resin being:(A) a fluorocarbon resin selected from the group consisting of (1) perfluoroalkoxy tetrafluoroethylene copolymer resin (PFA), (2) ethylenechlorotrifluoroethylene copolymer resin (E-CTFE), (3) ethylenetetrafluoroethylene copolymer resin (E-TFE), (4) poly(vinylidine fluoride) resin (PVDF), (5) tetrafluoroethylene-hexafluoropropylene copolymer resin (FEP), (6) poly(chlorotrifluoroethylene) resin (CTFE), or a mixture of two or more of said fluorocarbon resins; or(B) a polyether resin selected from the group consisting of (7) polyethersulfone resin (PES), (8) polyether ketone resin (PEK) and (9) polyether ether ketone resin (PEEK) or a mixture of two or more of said polyether resins;said additive being:(C) a poly(phenylene sulfide) (PPS); or(D) an inorganic crystalline ceramic powder and/or fluorocarbon resin when said resin is a polyether of (B) above; or(E) an inorganic material selected

Abstract: In gypsum board faced with a fibrous mat, for example, a mat of glass filaments adhesively bound together, improvements are realized by the use of a reinforcing resinous binder in the mat.

Abstract: A stand for supporting a packet of fanned computer printout sheets which enables easy leafing forwardly and backwardly through the packet. A rear backer plate is provided with a forwardly and upwardly extending bottom ledge designed to hold the packet in a positionally-stable upright position, and a lower substantially horizontal plate with associated ledge supports those sheets which are turned down in the packet. The rear backing plate and the lower substantially horizontal backer plate are preferably hinged to each other to permit folding-up of the entire support into a compact configuration, and the ledge for the horizontal plate is preferably hinged so it can be swung upwardly and inwardly of the horizontal plate for use with packets of sheets of lesser height. An integral horizontal rear flange limits the rearward tilt of the rear backer plate to the desired angle.

Abstract: A method of producing embossed decorative thermoplastic sheets by forming a laminate including a printable composition, having a relatively low viscosity and containing an effective amount of a blowing agent, between thermoplastic resin sheets. The printable composition is applied in a design pattern to a gelled thermoplastic resin on a support surface. A second layer of thermoplastic resin having a melt viscosity which differs from that of the first layer is applied to the printed first layer to form a composite structure. This structure is heated to decompose the blowing agent and effect foaming in selected portions of the resin layer having are established by the printed design pattern containing the blowing agent.

Abstract: A locking device for securing inner and outer telescoping cylindrical tubes in a selected relationship. A resilient collar attached to one end of the outer tube includes and inner annular flange extending in close-fitting relation between the inner and outer tubes. A locking screw extending through the outer tube is actuatable to bear against and resiliently circumferentially displace the inner flange to lock the inner tube in the desired position. The device is particularly suited for use with adjustable stands such as hospital IV bottle stands and the like.
