Abstract: ABSTRACT           Vinyl ester resins of the type already having reactive liquid polymers reacted into the backbone of the resins, are cured in the presence of a reactive liquid polymer additive admixed with the prereacted vinyl ester resin.  Heating of the system during cure causes the reactive liquid polymer additive to mis-cibilize with the vinyl ester base resin.  The vinyl ester resin modified in the manner described above shows a significant enhancement in toughness as measured by fracture energy over unmodified counterparts or counter-parts modified by known methods of adduction or admixing alone.

Title: Nonmetallic conduit fitting
Inventor: KLAS DANIEL E
IPC: F16L27/08
Filed: 1991-03-22
Abstract: A nonmetallic conduit fitting having first and second tubular members rotatably coupled about a transverse axis of rotation allowing the fitting to be used in a straight or in angled positions. The first tubular member has a plurality of latching tabs with each latching tab having a first surface that rotatably and slidably engages a second surface on a flange extending from the second tubular member. The first surfaces of the latching tabs and the second surface of the flange define a plane of rotation therebetween which is substantially perpendicular to the axis of rotation. The latching tabs are resiliently coupled to the first tubular member for providing a snap fit along the plane of rotation.      In the first embodiment, the latching tabs of the first tubular member engage an inwardly extending flange on the second tubular member via a snap fit. Abutment members are provided on the inwardly extending flange for engaging the gaps between the latching tabs to selectively retain the first and second tubular members in a straight, or angled position. In the second embodiment, the first tubular member includes an annular wall having a plurality of latching tabs that engage an outwardly extending flange of the second tubular member via a snap pit. An abutment member on the first tubular member engages notches formed on the peripheral surface of the outwardly extending flange for selectively retaining the first and second tubular members in a straight or angled position. The fitting also includes a ferrule and nut for receiving and coupling an electrical conduit to the second tubular member. The nut has a tapered internal wall that compresses resilient tines of the ferrule about an electrical conduit, when the nut is tightened onto the second tubular member.

Abstract: A suspension package of the type having a frame and a hammock tensioned across the frame to enfold and support a product is provided with a brace to prevent the ends of the frame from moving inwardly.  This brace simultaneously provides a safety net to protect the product being loaded into the hammock.   The hammock is secured to tensor flaps on the frame, and these flaps are provided with tabs which prevent the flaps from rotating inwardly past the plane of the end panels.  The hammock is folded in a double fan fold at its ends to facilitate top loading and to accommodate the widest range of product sizes and shapes.  Each of the tensor flaps has an inner part and an outer part, and the hammock end is sandwiched between the inner and outer parts and held in place by a double ended rivet which simultaneously operates to secure the tensor flaps in the hammock tensioning position.  Cinching devices are used around the hammock to center the product within the frame. Lifting slots and handles are disclosed for facilitating removal of the frame from a container.

Title: Air/fuel controller for internal combustion engine
Inventor: ORZEL DANIEL V
IPC: F02D41/00
Filed: 1991-10-03
Abstract: A system and method for controlling operation of an engine having a fuel vapor recovery system coupled between a fuel supply system and engine air/fuel intake. In response to a two-state exhaust gas oxygen sensor (EGO sensor), a feedback controller generates a desired fuel charge.  This feedback controller is also responsive to an adaptive learning controller which provides corrections for long term air/fuel offsets caused by such factors as fuel injector variances.  An adaptive fuel vapor learning controller measures fuel vapor concentration during purging operations of the fuel vapor recovery system.  This adaptive fuel vapor learning controller provides a fuel vapor correction factor which is subtracted from the desired fuel charge to maintain proper air/fuel ratio operation during a fuel vapor purge.  Purging operations are disabled when the measurement of fuel vapor concentration is below a preselected value.  At that time, the offset learning controller is enabled for a preselected time.  Purging operations occur until the learned measurement of fuel vapor content indicates purging is no longer necessary. Thereafter, adaptive offset learning is enabled for a preselected time.  After such preselected time, adaptive offset learning is disabled, purging operations recommenced, and adaptive vapor learning also reinitiated.

Abstract: In a vector calculation apparatus, a vector adder (21) produces an adder output signal (E) by calculating a three-term sum of a first, a second, and a third adder input signal which are produced in accordance with the adder output signal, a predetermined value ("0"), a first vector (A), and a second vector (B) under control of a control circuit (29).  A first selecting circuit (26) selects, as a first selected signal, one of the adder output signal and the first vector.  A second selecting circuit (27) selects, as a second selected signal, one of the adder output signal and the second vector.  A zeroth selecting circuit (24) selects, as a zeroth selected signal, one of the adder output signal and the predetermined value.  The vector adder is supplied with the first selected signal as the first adder input signal, with the second selected signal as the second adder input signal, and with the zeroth selected signal as the third adder input signal.

Abstract: A restrictor valve functions as an outlet valve in a metered liquid dispensing system and utilizes a spring biased, shiftable anti-siphon check valve to prevent fluid flow back from the receiving tank into the system.  The restrictor valve is attached to the delivery end of the system discharge hose.  The dispensing system is controlled by a central electronic unit and the restrictor valve includes a sensing unit for signalling the electronic control when liquid is present at the outlet.

Title: Process for the preparation of saturated primary fatty amines by hydrogenation of unsaturated fatty acid nitriles
Inventor: FRUTH ANTON
IPC: C07C209/70
Filed: 1991-12-13
Abstract: Process for the preparation of saturated primary fatty amines by hydrogenation of unsaturated fatty acid nitriles According to the new process, the hydrogenation of unsaturated fatty acid nitriles or mixtures of unsatu-rated and saturated fatty acid nitriles is carried out in the liquid phase in the presence of nickel catalysts or cobalt catalysts. In a first reaction step the fatty acid nitrile, in the presence of ammonia, is treated with hydrogenation hydrogen until all the nitrile groups are hydrogenated to predominantly primary amino groups. After the ammonia content in the reaction mixture obtained from the first step has been adjusted to a value of at most 0.1 mol of ammonia per mole of fatty acid nitrile used, a second reaction step is used to hydrogenate the double bonds present to saturated bonds. The desired primary and saturated fatty amine is obtained in a very high yield and has an iodine number of at most 5.
