Abstract: A die-cut paint masking part for use in masking a curved corner surface of an object to be painted comprises a flexible, paint-impervious mask, a layer of pressure-sensitive adhesive material permanently adhering to the underside of the mask, and a removable flexible protective liner releasably adhering to the adhesive layer. Prior to use and while flat, the masking part has a generally Y-shaped configuration and includes a base leg from which diverge a relatively wide branch and a relatively narrow branch. The base leg and wide branch have a common curved first edge. The base leg and narrow branch have a common curved second edge. A notch or cut-out to facilitate folding is formed at the point where the two branches converge. The protective liner is provided with two score lines, formed during die-cutting of the masking part from a web, which define three independently removable liner portions.

Abstract: Apparatus for drying a running paper web and floatingly suspending it without contact during the drying process, including air bars which are considerably larger than conventional air bars, for example, being about five and one-fourth inches square in cross-section, and being about three and one-half inches between their nozzle slots. These large air bars are spaced apart from one another along each side of the web a distance of about 15 inches. By so dimensioning the air bars providing the greater spacing between the air bars, considerably more drying capacity is provided, on the order of 14 percent, and requiring less energy input into the dryer. Web drying equipment for sealingly mounting the air bars on the air supply duct means so that the bars can be individually adjusted toward and away from the web can also be tilted or pivoted to change the angle of the drying air being discharged against the web.

Abstract: A plastic re-usable two-piece push-pin stand-off fastener for releasably securing together two spaced-apart circuit boards comprises a hollow body having a body bore into which, for pre-assembly, a pin is insertable into the body bore prior to use. The pin has large and small outside diameter portions near its head and insertion ends, respectively. The body bore has large and small inside diameter bore portions near its head and insertion ends, respectively. The body also has outwardly extending inwardly depressible resilient flexible wings adjacent the large bore portion, has outwardly expandable resilient flexible legs adjacent the small bore portion, and has an external shoulder between the wings and the legs. In use, the body is inserted into a hole in the first board to entrap the board between the body head and wings. Then, the body is inserted into a hole in the second board so that the shoulder bears thereagainst.

Abstract: The invention relates to a jaw crusher wherein shims behind a toggle beam define various positions of its fore-and-aft adjustment along way slots in which its end portions are guided, and wherein the toggle beam is shifted forwardly away from the shims and rearwardly towards them by a pair of hydraulic rams, each connected between the housing and an end of the toggle beam. At each end the toggle beam has a forwardly-downwardly inclined surface slidingly overlain by a wedging member that cooperates with the upper surface of the adjacent way slot to wedgingly prevent forward shifting of the toggle beam and confine it against the lower surfaces of the way slots. Each ram has link connections with the toggle beam and with a wedging member whereby the latter is pulled forward out of wedging relationship before the toggle beam is shifted forward and is pushed back to wedging condition after the toggle beam engages the shims.

Abstract: A method and suitable apparatus for periodically analyzing pulp stock, including wood pulp and water, in a pulp digester, to determine the amount of cooking to which the pulp has been subjected. The method includes taking a sample of the pulp stock from the digester, diluting the sample to a predetermined range of consistency, and determining the exact consistency of the sample. Next, the sample is transferred to a reaction chamber. A reagent is then added to the sample and allowed to react with the sample at a predetermined temperature. The light absorbance of the reagent during the reaction is continuously monitored during the reaction. After the light absorbance has clearly passed a peak, the value of the peak is combined with the consistency of the sample, previously determined, to arrive at the amount of cooking to which the sample had been subjected prior to the test, from a known relationship thereof to the light absorbance of the reagent and the consistency of the sample.

Abstract: The invention relates to a pressure vessel, particularly to a drier vessel for a vehicle air conditioning installation, and a method for making it. In the production of known pressure vessels, a hollow core body optionally provided with auxiliary winding bodies is provided with an outer winding layer of fibre-reinforced plastic acting to improve the resistance of the vessel to internal pressure. The production of such pressure vessels is rather expensive, because the core body and auxiliary winding bodies have to be separately prepared and formed to the desired shape of the finished pressure vessel.

Abstract: A re-usable two-piece fastener for releasably clamping two workpieces together comprises an expandable hollow plastic body for receiving an axially insertable and rotatable screw made of plastic or metal. The body comprises a slotted outwardly expandable shank having a head or flange at its outer end and a bore extending entirely through the body. The screw comprises a threaded shank having a head at its outer end. The body bore comprises an outer end portion of the same diameter as the threaded screw shank, an intermediate thread-engaging member having an aperture of the same diameter as the root diameter of the screw shank and sloped at the same pitch as the screw thread, and an inner end portion. The thread-engaging member may be integral with the body or may take the form of a metal insert. The inner end portion of the body bore may be of the same or larger diameter than the screw thread or may be of smaller diameter so that the screw thread can self-tap thereinto.

Abstract: A table supports a cardboard file unit body as it is manually slid edgewise forwardly, engaged against a fixed but adjustable side edge guide, into engagement with a fore-and-aft movable front edge guide and an air microswitch thereon that actuates a punch mechanism. After punch operation, the front edge guide moves forward, bringing the punched portion of the body between the wings of a metal tab waiting at a peening station. Arrival of the front edge guide at its forward position trips another air microswitch to actuate a tab peening mechanism. The tabbed body is then manually withdrawn rearwardly and a new tab is automatically fed rearward to the peening station from a stack of tabs in front of that station. The punching and peening mechanisms, front edge guide and tab feed slider are actuated pneumatically.
