Abstract: A die cut one piece interlocking outfold container has interlocking of inside and outside flaps. A cover length flap of the container folds outside of a body length flap, and cover width flaps fold inside of body width flaps. The particular configuration results in the container having plural thickness front, back and side walls, which increases the stacking strength of the container.

Abstract: A sampler for communicating with the interior of a vessel containing a slurry under pressure extracts a sample of the slurry from the vessel and conveys the same to a point of collection. The sampler includes a conduit having an inlet for communication with the interior of the vessel and an outlet to the exterior of the vessel, and a valve for selectively establishing and interrupting communication between the conduit inlet and the interior of the vessel. When communication is established, a sample of slurry flows into the inlet, through the conduit and to the outlet for collection, and when communication is interrupted a source of flushing liquid is coupled with the inlet to flush the conduit clean of residual sampled slurry. By virtue of introduction of flushing liquid through the conduit when slurry is not being sampled, residual slurry is prevented from settling out and/or hardening in the conduit and clogging the sampler.

Abstract: An improved method and apparatus for blocking semifinished lenses by the adjustment of each such lens until it occupies a prescribed position where an alloy hub or "block" is removable affixed to the lens by an adhesive pad so that the lens can be held for finishing, is characterized by magnetically securing the block to a chuck for carrying and affixing the block to the lens. The block may quickly and simply be secured to the chuck merely by being extended therein without the need for any mechanical devices, and upon being affixed to the lens is readily separable from the chuck upon withdrawal of the chuck therefrom.

Abstract: A sampler for communicating with the interior of a vessel containing a relatively viscous liquid under pressure extracts a liquid sample of predetermined volumetric displacement from the vessel and conveys the same to a point of collection. The sampler includes a body having a bore in communication with the interior of the vessel, a plunger reciprocable within the bore and a slider reciprocable within the bore rearwardly of the plunger. To obtain a liquid sample, the plunger is moved at least partially into the vessel to establish a sample chamber between the slider and plunger into which liquid flows. The plunger is then moved back into the bore with the sample captured between the plunger and slider until the sample is exposed to a discharge port in the bore, at which point further rearward movement of the sleeve is inhibited, so that continued rearward movement of the plunger forces the liquid out of the sample chamber and through the port.

Abstract: Novelty ornamentation such as for a cover in the form of a non-disposable sleeve for a disposable cigarette lighter of conventional design is disclosed. A novelty appearing and disappearing image presenting assembly is situated on one side of the sleeve and includes a filmstrip enclosed in a housing. The filmstrip has opaque portion having a desired color providing a permanent portion of the image and a translucent portion providing the appearing and disappearing portion of the image. A dark background is permanently situated behind the translucent portion of the filmstrip and a light colored shield is selectively positionable behind the translucent portion in front of the dark background. The shield is movable by gravity to and from a position behind the translucent portion of the image on the filmstrip, thereby to cause it to appear when the shield is moved behind and to disappear when the shield is moved away.

Abstract: A tamper proof, economically constructed, easily installed, drive recorder or instrument for making a permanent record of the manner in which a vehicle is driven is provided, and comprises an instrument which may be located in and secured to the vehicle of a driver whose driving habits are to be recorded. The recorder preferably has two compartments each having inclined bottom surfaces to normally position a heavy ball by gravity. The inclined bottom surfaces are provided with recording paper, and the vehicle's acceleration, braking or cornering causes the heavy balls to move from their normal positions up the inclined surfaces and the heavy balls to leave a track on the recording paper to make a permanent recording of the drive.

Abstract: To measure the flow rate of a fluid in a pipe, a heat pulse is injected into the fluid by a heat pulse generator, and the time of flight of the pulse between the generator and a sensor is measured. Arrival of the pulse at the sensor is determined by detecting a selected temperature level of the ascending flank of the pulse, and a predetermined temperature level of the descending flank is then detected to initiate generation of the next subsequent pulse. Since the temperature of the descending flank generally represents the temperature of the fluid between the heat pulse generator and sensor, the technique ensures that the accuracy of each successive flow rate measurement is not affected by residual heat from the preceding measurement, and yet enables measurements to be obtained at maximum frequencies. In one embodiment the measurements are used to control the flow rate of the measured fluid, and in another the flow rate of fluid in one or more additional pipes.

Abstract: A plural component flushless spray gun has a fluid outlet orifice defined by two opposed inlet orifices with a thin blade interposed therebetween. The blade prevents fluidic material exiting each inlet orifice from flowing directly into the other, and is slotted at its forward end to define a very small volume chamber into which the components flow for mixing prior to being emitted through the outlet orifice defined at the forward end of the slot. Because the chamber has a very small volume, the components are intimately mixed for better polymerization, and only a very small quantity of reactive components are mixed within the gun immediately behind the outlet orifice. Consequently, should the mixed components harden within the gun, only a limited amount of material is involved and the blockage may readily be removed simply by triggering the gun on to eject the blockage through the outlet orifice.

Abstract: A cam cleat includes a pair of spring loaded cams or pawls rotatably mounted on a base. The cams have specially formed teeth and open and close in opposite rotary directions to releasably grip a line therebetween. The cams or pawls are rotatably mounted on a shaft and the case by a plurality of rotatable bearings to substantially reduce the effort required in opening and closing the cams and to reduce the spring force maintained on the cams, resulting in substantial advantages in performance. An alternate single cam version is also disclosed.

Abstract: An improved method and apparatus for applying a film of coating material on a moving web of paper carried through an application zone, utilize a reservoir of liquid coating material established under pressure between liquid seals at forward and rearward ends of the zone, and a doctor blade loaded against the web rearwardly of the rearward liquid seal. The reservoir is formed by forward and rearward relatively movable, sealed members, the upper edges of which define gaps with the paper web and doctor blade, respectively, in which gaps the liquid seals are formed. Coating material is flowed under pressure and in excess into the application zone to enable a pressurized area of coating material to be developed therein against the web and immediately upstream of the doctor blade, with the excess of coating material overflowing from the zone through the gaps to form the liquid seals. The provision of two overflow routes for excess coating material aids in skipless application of coating on the web.

Abstract: Apparatus for applying a coating liquid to a moving web of paper carried through an application zone is characterized by a system at each side end of the zone for recirculating coating liquid thereat. In use of such an applicator coating liquid at the side ends of the zone tends to stagnate, and the recirculating system eliminates coating buildup in the side ends.

Abstract: An applicator for applying a coating liquid to a moving web of paper carried through an application zone, wherein the applicator has a chamber for receiving the coating liquid and an opening thereto for directing the liquid into an application zone and onto the web, the zone being established between a front wall of the chamber and a doctor blade extending from a rear side of the opening across and against the web, is characterized by a readily removable and replaceable orifice plate on the front wall, which extends toward and closely spaced from the web to define with the web a gap through which coating liquid in the zone flows to form a liquid seal. Because the orifice plate may readily be removed and replaced, orifice plates of different heights may be used with the applicator, so that simply by selecting a particular orifice plate for use, the gap in which the liquid seal is established may be made to have a predetermined size.

Abstract: A joy stick assembly is characterized by a joy stick resiliently mounted in an aperture through a hand holdable housing and normally biased to a neutral position.

Four contacts are positioned at 90.degree. increments around the sphere and out of contact therewith when the sphere is in its neutral position, and the joy stick is manipulatable to establish electrical connections between the sphere and individual ones or adjacent pairs of the contacts to provide a signal from the sphere to the contact or contacts.

Abstract: An electrostatic air atomization spray coating system having a hand held spray gun, wherein a flow of air to the gun is sensed to control energization of a high voltage power supply for electrostatically charging spray particles, is characterized by a bypass valve on the spray gun which selectively permits air atomization spraying with or without electrostatics.

Abstract: A friction material member particularly useful in high load and temperature applications and a method for making the same are disclosed. The friction material member is made by preparing a mixture of sinterable metal particles, carbonaceous material, friction enhancers and curable polymeric resin; the mixture comprising at least about 50 percent by weight of metal particles and sufficient resin to coat and bond the metal particles, carbonaceous material and friction enhancers. The mixture is molded and the resin cured to form a piece in a solid preformed shape corresponding to the shape of the mold. Thereafter, the preformed piece is heated in a substantially oxygen free atmosphere for a time and at temperatures and pressures sufficient to fuse at least a portion of the metal particles into a sintered metal matrix. The preformed piece may be sintered to a metal backing plate during the heating step, or may be welded, brazed or soldered to the plate after heating.

Abstract: An edge dam assembly for an applicator for applying a film of coating material on a moving web of paper carried through an application zone, is characterized by a seal element at each side end of the zone. To prevent leakage of coating liquid past the seal element, air is introduced through the element and into the side end of the zone adjacent to the element. The air forms an air barrier pocket at the side end of the zone, which is void of coating liquid, whereby coating liquid is maintained in the zone inwardly of the seal elements.

Abstract: A clip-on wear plate for protecting the downwardly facing surface in the pedestal opening of a side frame of a railway truck. The wear plate is especially adapted to be used on worn pedestal surfaces and comprises either a pair of separate plates or a plate with a central portion removed.

Abstract: An edge dam for an applicator for applying a film of coating liquid to a moving web of paper carried through an application zone, is characterized by a seal element at each side end of the zone for substantially sealing the side end of the zone, thereby to impede a flow of coating material out of the zone. At least one orifice is formed through the seal element outwardly of the zone, and the orifice is connected with a supply of water under pressure for directing a flow of water against the peripheral edge of the web moving therepast, thereby to wet the edge and flush the same of any coating material seeping past the element. In consequence, edge stickers and coating liquid pickup on the web edge are substantially eliminated.
