Abstract: APPLICATION FOR UNITED STATES PATENT     OFFSHORE STRUCTURE IN FRIGID ENVIRONMENT     ABSTRACT OF THE DISCLOSURE          An artificial ice structure for use as, for example, a base for oilfield operations or a road, is constructed in an offshore frigid environment where the water is covered by a sheet of floating ice.  A berm or dike enclosing a predetermined area is built on the ice sheet to contain flood water and a trench is cut through the ice sheet  around the perimeter of the dike to separate the predetermined area from the parent ice sheet and thereby form an island.  The island of predeter-mined area is flooded with water and the water is allowed to freeze and weight the island down until essentially the entire ice mass of the island is resting on the ground underlying the body of water.  After the structure is grounded, flooding with water is continued until the island has sufficient mass, in combination with other defensive measures, to resist the forces imposed by move-ment of the surrounding fast ice.  When designed to sup-port a base for oilfield operations, a silo arrangement, which extends through the ice structure and into ground below the mudline, is utilized to install separable well control equipment below the ground level.  Also, a large level operating surface of a desired elevation above the surrounding ice is formed.  The silo arrangement is also applicable for use with islands formed wholly or partly of fill materials.

Abstract: BOTTOM SILO UNLOADER                  Abstract of the Disclosure A silo unloader for a bottom unloading type silo having a discharge opening in the bottom wall thereof comprises a housing adapted to be mounted in said opening and including an upper wall having a shaft opening.  The shaft is supported on bearings in the housing below the upper wall and the shaft extends upwardly through the shaft opening into the silo for supporting a plurality of flexible silage dislodging members which rotate with the shaft.  A rotary seal between the shaft and the shaft opening in the upper housing wall comprises an inside annular collar around the shaft extending upwardly of the upper wall of the housing and an outside annular collar around the inside collar and supported by the shaft to project downwardly below the upper end of the inside collar forming an overlapping seal between the relatively rotating collars.  The lap seal prevents silage, water or other materials from moving downwardly through the shaft opening in the housing wall around the shaft and thus shields the bearings in the housing resulting in longer bearing life and reduced maintenance.

Abstract: ABSTRACT OF THE DISCLOSURE          Apparatus for measuring the ignition timing of an internal combustion engine of the type having a pulse generator for indicating when the flywheel is in a pre-determined position subsequent to top dead center and in which a pulse of predetermined amplitude is initiated by a signal from one spark plug and is terminated by a signal derived from the pulse generator.  Correction is made for the reference angle between the top dead center position of the piston and the occurrence of the signal from the pulse generator by algebraically adding to the pulses a DC correction which is adjusted to conform with the knows: reference angle.  The adjusted pulses are applied to a meter to indicate the amount of ignition advance or retard.  A second meter indicates the amount of the correction voltage.  The apparatus also has novel cal-ibrating means for applying to the timing device two spaced voltage pulses spaced apart by the distance of a half cycle of a periodically varying commercial voltage of known frequency.  A second periodically varying voltage is derived from the first periodically varying voltage by a frequency divider so that there is a definite fre-quency relationship between the two voltages.  The width of a half cycle of the first voltage pulse thus has a predetermined angular relationship to the half cycle of the second voltage.  The apparatus is calibrated by ad-justing the apparatus so that the angular relationship displayed on the reference angle meter corresponds to the angular relationship between the two frequencies.

Abstract: Abstract A resin reinforced fiber structure is formed by drawing fibers under tension, in spaced relation to each other through a bath containing a molten heat curable resin, combining the fibers in mutual contact for removal of excess resin, spreading the fibers for passage through a preheating zone and then in a recombined state through a plurality of radiant heating zones and relatively narrow cold shaping dies in series.  The preheating and heating zones provide heated surfaces in spaced relation to the resin coated fibers, effect a viscosity break to enable the resin to more completely wet the fibers and advance polymerization towards a gel point.  The narrow cold shaping dies provide the desired shape to the final article and remove excess resin as cure is advanced. The fiber reinforced resin structure at about the resin gel point is passed through a final cold shaping die, and then to a final curing zone.

Abstract: BED FRAME            Abstract of the Disclosure A bed frame having a novel leg structure.  The bed frame includes a right angle side rail, and a cross rail pivotally connected to that side rail for swinging movement between a storage position in which the cross rail is oriented parallel to the side rail, and a bed support or use position in which the cross rail is oriented normal to the side rail.  The novel leg structure includes, in preferred form, a leg member having a U-shaped cross section at the top end thereof, the leg member being fixed to the cross rail adjacent the cross rail's pivotal connection with the side rail.  A latch tab is connected with the leg member's center web by a neck having a width less than the width of the latch tab, the latch tab being spaced above the leg member's top edge.  The latch tab, neck and leg member's top edge cooperate to define two slots which open away from one another in generally mirror relation.  In use, and as the cross rail is swung from the storage attitude to the use attitude, the side rail's horizontal web is received in one of the slots, i.e., the side rail's web is located between the latch tab and the leg's top edge.  This supports the cross rail relative to the side rail when the bed frame is erected.  The same leg member may be mounted to a cross rail on either end of that cross rail, i.e., the same leg member structure may be used at either of the bed frame's two corners defined by that cross rail without regard to left hand side or right hand side of the bed frame, because of the two slot structure.
