Abstract: Abstract of the Disclosure A novel heat exchanger structure, for a hand-held adhesive gun of the type adapted to discharge a heated thermo-plastic adhesive through a discharge valve located in the gun's barrel. In preferred form, the novel heat exchanger includes a heat exchanger core fixed in location within a heater body's bore.  The heat exchanger core has spiral threads on the outer surface thereof, and the bore's surface has spiral threads thereon, too.  The heat exchanger core's threads are sized relative to the inlet bore's threads such that the core can be threaded into the bore, and such that the threads cooperate to define a spiral path about the core through the bore from one end to the other, thereby defining a spiral heat exchange path through the gun's heater body.  This novel heat exchanger is particularly adapted to elevate the temperature of the molten adhesive, just prior to dispensing it, above that temperature level at which the molten adhesive is supplied to the hand gun.

Abstract: " POWER DUMP WAGON " ABSTRACT OF THE DICLOSURE          A chassis supports a main frame with one open side, and a dump box with an open upper side is situated  within the main frame and pivoted to the other side of the main frame. An hydraulic piston and cylinder assembly can move the box from the vertical or normal position to a tilted or unloading posi-tion.  The dump box is pivoted to the upper side of the main frame at a line spaced from the top side edge of the dump box so that the top side edge extends beyond the side of the wagon when tipped or tilted.  A conveyor is situated on the side of the dump box which is pivoted to the main frame and driven by an hydraulic motor.  Material is loaded in the open upper side of the  dump box and when it is to be unloaded, the dump box is tilted whereupon the conveyor unloads the material from the open upper side of the dump box.  This construction overcomes disadvantages of conventional dump boxes in which the center of gravity is shifted considerably when dumping by gravity, par-ticularly when the load is such that it resists sliding move-ment during dumping.  Furthermore, conventional dump boxes are usually pivoted adjacent the top edge thereof which dumps the load close to the side of the receptacle into which it is being dumped rather than towards the center as with the present device due to the fact that the upper edge of the box is spaced away from the chassis.

Abstract: RECLINER CHAIR WITH WALL-AVOIDING ACTION      ABSTRACT OF DISCLOSURE         A handle-operated recliner chair has a seat mount-ing linkage consisting of two mounting links mounting the seat directly to a stationary base for movement between nor-mal and reclining positions.  A footrest is mounted to the front of the seat by a footrest linkage which is extended and retracted through means of a handle mounted relative to the seat to rotate a torque tube which is connected to the foot-rest linkage to operate the same.  One of the links of the footrest linkage is directly connected to the front mounting link of the seat such that extension of the footrest will cause the seat mounting links to pivot forwardly to not only place the seat in an inclined position but also, to move the seat forwardly relative to the base to provide wall-avoiding action which comes in to play when the backrest is reclined to avoid striking a nearby wall with the backrest.  The back-rest may be either fixed rigidly to the seat to move together with the seat as a unit to provide a "one-way" recliner or as an alternative, it may be mounted by means of a novel back-rest linkage to the seat to move relative to the seat to pro-vide a "three-way" recliner chair.  In either instance, the backrest linkage is totally independent of the seat mounting linkage and the footrest linkage.

Abstract: VAGINAL CONTRACEPTIVE                           Abstract The present invention encompasses devices which are used in the vagina to deliver spermicidal sur-factants.  These devices can be inserted by the user, and do not require insertion by a physician as, for example, in the case of intrauterine contraceptive devices.  By virtue of their unique construction and shape, the devices herein are foldable for easy in-sertion.  Once in position at the cervical os, the devices open to "cap" the os and remain in position, even during intercourse, so that access of the spermi-cidal surfactant source to the cervical os is not interrupted.  The devices are designed to remain comfortably in the vagina during the time between menstrual periods to provide desirable, prolonged release of a spermicidal surfactant, and their con-struction and shape facilitate retention therein while minimizing awareness and discomfort.  An effective between-period contraceptive device is thereby provided.

Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus for washing cellulose pulp including a drum with a filtering member on its outer shell and stationary hous-ings encircling the drum.  A pressurized washing liquid is applied against the cellulose pulp which is in the form of a fiber web upon the filtering member and compartments affixed within the drum receive a suspension liquid displaced from the washing liquid.  Pure washing liquid introduced against the ro-tation of the drum is applied against the fiber web forcing suspension liquid to pass through the filter and into compart-ments under the housing.  A valve combines the suspension liquid flow from the compartments and conducts the flow to a supply connector at the next-to-last housing taken in the direction of rotation of the drum.  This displaced suspension liquid dis-places liquid from the pulp web with flow resistances encounter-ed by the washing liquid between different housings causing pressure differential between washing liquids in different housings.  Leakage of washing liquid caused directly from one housing to the next or leakage of suspension liquid displaced from within the fiber web is inhibited by radial lamellae cooperating with the drum and unperforated zones adjacent the housings.  Spacing of the lamellae on the drum circumference is less than the length of the unperforated zone so that during drum rotation there is at least one lamella in sealing contact with each unperforated zone located between the housing walls.

Abstract: ABSTRACT OF THE DISCLOSURE           A water play toy shaped in the form of an animal or cartoon character in which the body is provided with an outlet section which has a plurality of flexible hollow tubes attached to water outlets spaced around the outlet section.  A source of water under pressure is coupled to a conduit passing through the body and communicates with the outlet section for distributing water to the hollow tubes.  When the water pressure is turned on, a plurality of individual jets of water are emitted by the individual tubes.  Because the tubes are flexible they writhe and twist in a random motion pattern due to the action and reaction forces of the water acting on the tubes.  In one embodiment a first enclosed chamber compresses the outlet section.  A second enclosed chamber is built into the upper interior portion of the first chamber which communicates with a small pinhole type outlet to provide a misting or fogging aspect to the overall water pattern emitted by the water play toy.  As long as water pressure is uninterrupted water continues to flow through the flexible lines and the fogger creating a pattern of small waving streams of water within which a heavy mist pattern of water droplets is interspersed.  The result is around 360° pattern of water distribution around the toy.
