Abstract: METHOD AND APPARATUS FOR BLOW MOLDING                   ABSTRACT OF THE DISCLOSURE      A method and apparatus utilizing perform and final blow molds for forming molecularly oriented thermoplastic articles. According to the method, an extruded tubular parison is positioned within the pre-form blow mold and blown to preform configuration. The blown pre-form is then conveyed, while suspended from a moveable carrier, through a thermal conditioning chamber and the temperature of the pre-form is adjusted to within the range for molecular orientation. Next, the thermally conditioned pre-form is conveyer by the move-able carrier to a finale blowing station where the pre-form is blown to the configura-tion of the finale article. In a first disclosed embodiment, the carrier is a blow pin which is inserted into the tubular parison at the pre-form molding station prior to the first molding operation. In the second embodiment, the carrier is a tubular projection telescopically inserted into the blown pre-form prior to entry of the pre-form into the thermal conditioning chamber, and the pre-form is blown to its final shape by a blow tube inserted through the carrier. In both embodiments, the carriers are used to convey successive pre-form in continuous molding operation.

Abstract: TWO-CYCLE INTERNAL COMBUSTION ENGINE HAVING HIGH SWIRL COMBUSTION CHAMBER                    ABSTRACT OF THE DISCLOSURE     Disclosed is a two-cycle, internal combustion engine including an engine block, and a cylinder in the engine block having a head and generally opposed inlet and outlet walls respectively including at least one intake port through which a fresh charge is admitted into the cylinder and at least one outlet port through which exhaust gases are exhausted from the cylinder.  A piston is mounted for reciprocative movement inside the cylinder between a first position spaced from the cylinder head wherein the intake port is uncovered, a top dead center position, and a third position wherein the piston approaches the top dead center position.  The piston has a top, an inlet face por-tion which periodically covers and uncovers the intake port and an outlet face portion which periodically covers and uncovers the outlet port.  The piston and cylinder have a configuration causing increased swirling of the fresh charge in the cylinder as the piston moves from the third position to the top dead center position.  The piston and cylnder are constructed so as to form two spaced apart chambers in the cylinder when the piston is in the third position and for causing that portion of the charge in one of the chambers to be forced into the other of the chambers as the piston moves to the top dead center position.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to oil-soluble, metal-containing sulfonated polymers useful as additives for lubricating oils or hydrocarbon fuels and which are effec-tive as dispersants.  Such polymers of high molecular weight are also useful as viscosity-index improvers for the lubricating oils.  The polymeric dispersant additives are ionic polymers which comprise a backbone substantially soluble in the fuel or lubricant, and pendant ionic groups which are sulfonic acid groups neutralized with a metal compound.  Polymeric dispersant additives of this type may be made which are also capable of imparting excellent viscosity improvement, varnish inhibition, oxidation inhi-bition and detergency to the lubricant.  These additives may also impart rust preventive properties to the oil or fuel, and as V.I. improvers they can be formed to have particularly good low temperature viscosity effects in lubricating oil.

Abstract: IMPROVEMENTS IN OPTIMAL START PROGRAMMER                Abstract of the Disclosure An optimal start programmer for starting a heating or cooling cycle for an intermittently occupied building includes a digital counter which is enabled at the start of a pre-occupancy "search" period and accumulates counts from a timing source.  A digital to analog converter is responsive to the cumulative output count of the counter circuit for generating a staircase or ramp signal which provides a time-variable set point signal during the search period.  In the heating mode, the reference signal to the digital to analog converter is a signal representative of the outdoor ambient temperature; and in the cooling mode the reference is a constant signal.  The operating mode of the system during the search period is determined by a mode selection circuit which is responsive to a heating mass signal and a cooling mass signal to automatically determine whether the system is to operate in a heating mode, a cooling mode or an inhibit mode in which neither the boilers nor the chillers are actuated.

Abstract: ASSEMBLY OF THE DISCLOSURE         Hitch assemblies for vehicles, particularly vehi-cles such as trucks, are inconvenient when not in use be-cause they extend behind the vehicle and often interfere with ancillary equipment such as auger hoppers, elevator grates and the like as well as causing damage to other equipment associated with the vehicle, particularly when the vehicle is being positioned by backing up.  The pre-sent assembly avoids these problems by being extendable for use and retractable under or between the frame for storage purposes.  One embodiment swings rearwardly for use and forwardly for storage and is detachably locked in either position.  Another embodiment includes a tongue which is locked in the extended rear position when in use and then can be moved forwardly over a frame member and be locked in this position which is the stored position.          An alternative embodiment shows the hitch assembly pre-assembled in a subframe which can be attached to the ve-hicle as a unit.
