A boom loader of the kind having a boom from which is suspended a pipe in which petroleum products are conveyed from ship to shore, and provided with a universal connection between a discharge manifold on the pipe and the free end of the boom by means of which bending moments, which tend to arise where the boom is connected to the pipe, are reduced to a minimum. This invention relates to a boom loader of the kind having a boom from which is suspended a pipe in which the material to be loaded is ...

A support frame for use with an infant's car seat-bed assembly or as a shoulder supported pack carrier, the support frame including hook portions at one end thereof adapted to engage the upper edge portion of the back of a car seat when used with an infant's car seat-bed assembly, or on the shoulders of a person when used as a pack carrier; the opposite end of the frame having a detachable hook member adapted to engage the lower edge portion of the back of a car seat, the frame also includes soc...

A sealing ring for making a fluidtight joint between the opposing faces of two pipe flanges, the sealing ring being made on an elastomeric material and having an annular portion shaped to be retained in sealing relationship with a seating formed in one of the pipe flanges and an annular flange adapted to engage and be deflected by the other pipe flange so as to establish a sealing relationship with the said other pipe flange.

A truck mounted crane has a three-part, extensible boom in which telescopic motion is accomplished by a pair of extension cylinders contained within the boom. Frictional forces between the slidably mounted boom sections are minimized by improved pad assemblies positioned at selected bearing points. Support members in the form of rollers are positioned within the boom immediately above the lower extension cylinder to not only prevent the extension cylinder from buckling under full load conditions...

A compensated high voltage suppressor for insertion in a transmission line is shown for shunting large interference voltages from the line to ground. The suppressor has a varistor material through which the large interference voltages are shunted, and this material also functions as a capacitor dielectric. Additional circuit components are connected with this capacitance to form a low pass filter in the transmission line which has a characteristic impedance substantially matching the line charac...

A template has a tab portion in which a special character is formed. The template is insertable into the tape discharge opening of a label-making machine and the tab is positioned in an image-forming station at which the special character is formed on an ultraviolet light sensitive label material when the machine is operated.

A breakout wrench for drilling apparatus includes a pivotably mounted slide arm upon which a carriage is slidably mounted and a set of wrench jaws which are attached to a wrench arm swingably disposed upon the carriage for engaging and loosening a drill string section of the drilling apparatus. A hydraulic cylinder associated with and disposed beneath the slide arm is attached to the carriage to provide movement of the carriage along the slide arm and impart a wrenching movement to a drill strin...

A piano hinge type metal belt conveyor has hollow hinge rods connecting adjacent conveyor plate sections. Left and right hand roller chain assemblies each include a plurality of shafts each mounting sleeve bearings and rollers on the sleeve bearings. The shafts are interconnected by overlapping side wings each mounted at one end about one of the shafts and at its other end about the sleeve bearing on an adjacent shaft. Overlapping chain links disposed to the outside of the rollers may also be us...

A diverter spout is shown in which the diverter mechanism reciprocates vertically within a chamber of the spout and includes a valve stem with a valve head at the lower end and a piston at the upper end. When the diverter mechanism is raised into a diverting position the valve head mates with a valve seat to cut-off water flow from the spout, and the piston is moved into a position wherein water pressure is removed from its upper side, so that pressure on the lower side is sufficient to retain t...

There is disclosed a rotating biological contactor formed of abutting thin wall sheets arrayed along a central hollow square shaft. The contactor takes several forms. In some forms, the sheets are identical vacuum formed sheets joined face-to-face and back-to-back to define a plurality of spaced radial passages open to the perimeter of the contactor and series of concentric passages extending between, and opening into, adjacent radial passages. The identical sheets may be continuous or built up ...
