Abstract: A trailer tow connector for a vehicle used in towing a trailer includes a housing that has first and second bodies that respectively provide first and second electrical connections. The housing has laterally spaced apart hinge posts. A spring is arranged relative to first and second covers. The first cover has a central hinge portion, and the second cover has lateral hinge portions, the first and second covers respectively over the first and second bodies. Lateral hinge portions are arranged laterally outside the hinge posts, and the lateral hinge portions provide a portion of an aesthetic perimeter, the portion conceals outer sides of the hinge posts. A pin extends through a hole in at least one lateral hinge portion, and through the central hinge portion, the hinge posts and the spring.

Abstract: A trailer tow connector for a vehicle used in towing a trailer includes a housing that includes a body that has a cavity with electrical terminals that are configured to be in communication with a vehicle's electrical system. A cover is supported on the body and movable between a closed position in which the cavity is enclosed by the cover and an open position in which the cavity is accessible. A light is arranged in the housing and configured to illuminate the electrical terminals with the cover in the open position.

Abstract: An apparatus for producing and storing electrical energy includes a conventional bicycle having a plurality of gear ratios and a generator that includes a drive roller on a shaft that is in frictional engagement with an outer circumference of a rear tire of the bicycle. The bicycle is adapted for stationary use with a stand or independent use without the stand and is capable of producing electricity in either case. The generator charges a battery that may be transported with the bicycle. An inverter converts DC into AC. A mass is optionally added to a bicycle crank or wheel to smooth out the pedaling process. A pivoting modified stand is described.

Abstract: The novel 2R,4S-2-ethyl-4-[(4-phenoxyphenoxy)methyl]dioxolan of formula I ##STR1## can be used as a pesticide. It is used to control especially insects in fruit and citrus crops.

Abstract: The invention relates to the 3-(1'-hydroxyethyl)-2-azetidinone of formula ##STR1## which can be transformed into 4-acyloxy-3-(1-hydroxyethyl)-2-azetidinone derivatives. The latter can be used as starting materials for the manufacture of a large number of highly active .beta.-lactam antibiotics.

Abstract: The invention relates to a novel process for the manufacture of (3R,1'R)-4-acyloxy-3-(1'-hydroxyethyl)-2-azetidinones of formula ##STR1## in which R.sup.1 represents lower alkyl or aryl, by enantioselective reduction of the carbonyl group in a suitable .alpha.-acylaminomethyl-acetoacetic acid ester, cyclization of the resulting .alpha.-acylaminomethyl-.beta.-hydroxybutyric acid ester to a 5,6-dihydro-1,3,4H-oxazine with inversion of the carbon atom carrying the hydroxy group, equilibration to form the preferred trans-substituted dihydrooxazine, recleaving to form the configuratively uniform .alpha.-aminomethyl-.beta.-hydroxybutyric acid, ring-closure to form the .beta.-lactam and oxidative acylation at C(4) of the .beta.-lactam. Compounds of formula I can be used as starting materials for the manufacture of .beta.-lactam antibiotics. The invention relates also to novel intermediates.
