Abstract: A tool for removing paint from sheet metal gutters having a central ogee portion connected to two straight, vertical portions. The scraper includes a flat blade having an edge whose contour matches very closely the shape of the gutter. In particular, it approximates the exterior configuration of the gutter on a transverse cross-sectional view. The contour, however, has a slightly greater height than that displayed by the gutter; this allows the horizontal extensions of the blade to pass over the upper and lower edges of the gutter to effectuate contact with the gutter's vertical face. Cleaning the upper and lower horizontal surfaces of the gutter then merely requires shifting the blade downward to clean the former and upward for the latter. An extended handle on the blade allows its use by a workman located at some distance from the gutter. To further facilitate its use at a distance from the gutter, the handle may pivot relative to the blade.
Abstract: A resilient assembly comprising two resilient members so constructed as to provide a selected stiffness factor. In its fundamental form the assembly, when embodied in a practical structure, such as a fishing rod, and subjected to a load transversely applied to one end or along its length, functions similarly to a conventional tapered fishing rod up to some predetermined limit of flexure and, upon reaching such limit, additional resistance to flexure is introduced automatically.
Abstract: An adjustable bracket adapted to be secured to a rigid surface and firmly held in a selected position over a wide range. Its paramount advantage is the ease with which the adjusted position may be realized and the object rigidly held therein against vibration and shock.
Abstract: Disclosed is a method and apparatus for calcining or heat treating finely divided solids to effect a change in physical and/or chemical properties and, in so doing and prior to exhaust, filtering out particles entrained in the exhaust.
Abstract: A tamper-proof, one-piece device for securement to a receptacle for a fluent substance, the device including a membrane to seal the contents of the receptacle prior to initial use but which is rupturable through the medium of a piercing point to enable pouring of the contents. The membrane-puncturing element serves as a stopper to inhibit leakage and evaporation during periods of non-use.
Abstract: A resilient diaphragm separates one side of the rotary seal, such as is used to seal the space between a rotatable shaft and an adjacent surface of a machine housing through which the shaft extends. The seal assembly employs a casing which is secured to the housing and contains, or has adjacent thereto, parts of the seal including a sealing ring or pad which has rubbing contact with a pad on the housing. The sealing ring which, in turn, retains certain parts of the assembly, is held to the casing by means of an annular flange engaged behind a flange of the casing by the use of resilient parts put together with a snap fit. That is, the flange of the sealing ring is forced past the flange of the casing while both parts undergo momentary deformation. Thereafter the sealing ring is semi-permanently retained in the assembly by the casing flange. The present invention has reference to improvements in the resilient diaphragm which isolates one side of the rubbing surfaces from the other side.
Abstract: A temperature measuring probe utilizing an RTD element and an improved mode of assembling the element in a reliable manner which is proof against shock and vibration. Specifically, the invention has its most important applications in connection with miniaturized RTD's.

Abstract: The present disclosure relates to a diffusion plate to partition one space from another and pass a gas through ports in the plate in a flow pattern which is uniform over the area of the partition. Specifically, the disclosure relates to a diffusion plate, sometimes referred to as a distributor plate, having the aforesaid functions in connection with fluidized bed apparatus.
