Abstract: A boat hull having a bow and stern and requiring relatively small draft, having low frictional drag characteristics for high speed, stable performance, wherein the hull has a scooped configuration and defines a tri-keel design, wherein the side and bottom walls, making up the hull, define a first, open scoop portion and a second primary keel portion. The open scoop protion is of concave, curvilinear configuration and extends to a point rearwardly of the mid-point of the hull where it merges into the second or primary keel portion. The bottom and side walls of primary keel portion are V-shaped in configuration to thereby define the primary keel which extends from the merging surface to the stern. The first and second portions also cooperatively define about co-extensively therewith, extending from the open scoop portion, a pair of spaced apart secondary keels which extend from the approximate box of the hull to the stern thereof.

Abstract: A safety liner for retaining liquids in a confined volume wherein liquid impervious side and bottom walls are positionable into the liquid retaining position by reason of flotation means or buoyant portions maintaining the side walls in the liquid confining relationship to prevent liquid spills and runoffs. An exemplary use of the safety liner is as a safety flotation liner for use in waterbed structures wherein inadvertent rupture of the water mattress will prevent water spills by reason of use of the flotation liner, which will permit emptying of the escaped water in a safe and efficacious manner without damage to the surroundings.

Abstract: A horizontally reciprocal ram is movably supported on a can bodymaker for forward and rearward movement of a ram forward end through a die assembly by stationary, spaced, hydrostatic oil bearing sleeves located rearwardly of the die assembly thereby isolating at least a major portion of the ram for support and alignment for remainder of the bodymaker. Drive mechanism supplying horizontal ram drive to a ram rearward end may include a movable hydrostatic oil bearing slide connected to the ram through various optional forms of drive connection means supplying varying degrees of relative flexibility between the ram and slide to thereby determine the degree of ram isolation by the bearing sleeves with an optimum of substantially full ram isolation. Included in certain of the drive connection means providing greater flexibility for greater ram isolation are variously located hydrostatic oil bearing pad assemblies.

Abstract: A reciprocal ram at commencement of a forward stroke engages a cup-shaped article carrying it through metal working dies and against a doming die at reversal into a rearward stroke immediately followed by stripping of the article from the ram. The ram has an internal chamber constantly fed pressurized air through a rearward restricted orifice, the chamber opening freely of the ram forward end portion and internally of the article when thereon. By preselecting orifice size, chamber and article volumes matched with air pressure, a predetermined volume of air at predetermined pressure is confined in the ram forwardly against the article immediately prior to stripping and preferably engagement of the article by an external stripper results in an internal stripping assist by the confined pressurized air, the increasing exposed volume of the article increasing the air confinement volume reducing the air pressure progressively to substantially atmospheric at completion of article stripping.

At least one forward cylindrical projection on the frame slidably pressure abuts facing vertical surfaces within a back wall recess of the container during pivotal insertion into and while the container is in the soap supplying position, the projection and recess preferably being horizontally offset relative to the container vertical centerline, all to positively locate and stabilize the container in the dispenser.

Abstract: In stanchions of the type used for milking and/or feeding but primarily the feeding of cattle, a stanchion structure having vertically spaced upper and lower horizontal members with swing pipes defining spaced positions for accommodating cattle in spaced, captive relationship and having intermediate vertical support posts, an improved structure is provided employing an extending draw bar having spaced notches or slots wherein a locking member is pivotally secured to each of the swing pipes so that the individual swing pipes may be selectively opened or closed either individually or in unison to permit free access or egress from the spaced, cattle positions by the cattle and wherein the locking mechanisms are protected by the swing pipe structure so as to inhibit opening of the locking mechanism by cattle. The invention is also directed to a conversion kit for existing stanchion structures to provide for the locking feature in a simple and economically feasible manner.

Abstract: A doorlatch knob assembly has a knob insert of a hollow knob projecting through a door mounted rose secured rotatable by a drive washer which, in turn, receives the outer end of a doorlatch connected spindle projecting outwardly through the drive washer drivingly engaged therewith, through the insert and into the hollow knob. A fire resistant shield is closely telescoped and engaged with the insert receiving the spindle outer end therein so as to close off the previous opening from the hollow knob inwardly and preserve the integrity of the spindle retainment of the doorlatch mechanism against flame penetration upon heat destruction of the knob. The shield may have formation engaging the spindle outer end to aid the drive washer for rotatably driving the spindle. Where a turnbutton shaft is involved, it will also be formed of fire resistant material and will be closely telescoped by the outer end of the shield, otherwise the outer end of the shield will be closed.

Abstract: A roll holder of the type for mounting split-core rolls of tissue is positioned in a dispenser moveable from an upper dispensing position to a lower exhausted position. A latch retains the roll holder in the dispensing position until tissue exhaustion permits relative movement between the split-core parts with consequent roll holder part movement to release the latch for movement of the roll holder to the lower exhausted position. The improvement includes blocking members at roll holder opposite ends normally retained inactive permitting the foregoing latch release by presence of the split-core parts, but automatically moving to active preventing latch release upon a lack of core retention. This means that the split-core must remain for proper roll holder functioning, and also that a solid core roll cannot be used with core stripping to cause roll holder functioning, in either case avoiding core stripping from the roll holder which can result in littering.

The panels are prefabricated on the factory site with a variety of exterior surfaces and are shipped to the building or job site where they are easily positionable into partition wall-forming members permitting the erection of partition walls in relatively short periods of time compared to existing prior art expedients. The resultant wall is fire-resistive and aesthetic in appearance.

Abstract: An end of an inlet tube communicates through a tank wall with a water supply and an inner end of the inlet tube communicates through a float controlled valve with a generally vertically downwardly extending outlet tube. Thus, the tank water level through the float controls closing and opening of the valve admitting water through the inlet tube, through the valve and down the outlet tube flowing into the tank from the outlet tube lower end. The outlet tube is selectively vertically adjustable to adapt to various depths of tank by being formed of telescoped parts normally retaining a determined telescoping by a projection of one part being radially interengaged in a groove of the other part. Depending on the particular construction, the tube part telescoping may be selectively varied by either relative rotation between the parts or by disengaging and reengaging the interengagement between the parts. Through a slot and lock collar arrangement, the tube parts may be totally telescopically separated.
