Abstract: A method of manufacturing a polyolefin using a catalyst system of an ingredient (A) and ingredient (B), with ingredient A being obtained through successive reaction steps. Ingredient A is prepared by forming a mixture of (1) the combination of (a) metallic magnesium or an oxygen-containing organic compound of magnesium with (b) a mixture of a monohydroxylated organic compound and a polyhydroxylated organic compound, and (2) oxygen-containing organic compounds of titanium. The resulting solution is reacted in sequence with (3) at least one first halogenated aluminum compound, (4) at least one silicon compound and (5) at least one second halogenated aluminum compound. Compounds 3 and 5 are added at temperatures not exceeding about 25.degree. C. Ingredient B is an organometallic compound of metals from Group Ia, IIa, IIIa or IVa of the Periodic Table. The resulting free-flowing polyolefin is characterized by a large average particle size and small amount of fine particles.

Abstract: A quick release, two part electrical connector assembly immediately responsive to an external axial release force transmitted thereto without interfering with manual uncoupling rotation seats the foot (58) from each of three locking fingers (56) against a bayonet pin (24) from the mated receptacle, each finger extending longitudinally from a locking ring (50) on the plug and adapted to be pulled outwardly of a coupling ring (30) as a result of the bayonet pins transmitting releasing forces to the feet. The locking ring is completely enclosed within the coupling ring and a coil spring (46) is disposed in an annular cavity (70) formed between the rings to resist forward axial movement of the locking ring relative to the plug part. A waved washer (28) seats against the plug flange (14) to bias the locking ring axially rearward.

Abstract: A set of three annular ribs (44,46,48) disposed annularly around a crimp sleeve (28) are crimped radially inward about a coaxial cable (10) having a forward end portion (20) of its cable braid (16) exposed and folded backwardly, the ribs when crimped inwardly providing cable retention, electrical circuit path between the sleeve and braid, and in a moisture seal adjacent the rearward end face (38) of the sleeve.

Abstract: A tubular sleeve of a deformable plastic is longitudinally slotted to define a plurality of laterally separated axially weakened longitudinal columns (62) the respective forward leading edges (64) of which being inserted into an annular passageway (32) formed between an insert (20) disposed in a shell (10) so that the columns curl about and the column medial portions (66) collapse in an accordian-like fashion whereby to radially interferencingly wedge and lock the columns in the passage and thereby to retain the insert in the shell. The curling could be 180.degree. causing the leading edges to retreat coaxially rearward or be 270.degree. causing the leading edges to loop about and be driven radially outward, the leading edges in either possibly engaging its rearward medial portion.

Abstract: Vehicle safety belt with two shoulder belt parts anchored behind the upper back rest area on the one hand and in the area at the bottom of the seat on the other and with a lap belt part releasable by means of a belt buckle and tongue, said belt lap part being anchored in the area at the bottom of the seat on each side of the occupant, characterized in that the lap belt (3,4) and the shoulder belts (1,2) are fastened to each other above their lower anchoring points (7 to 10; 41, 42) by guide members (6,6'; 40) disposed in the area of the line of contact (39) between seat cushion (36) and back rest (30). Both shoulder belt parts (1,2) have a single upper anchoring point (11) and all belt parts (1 to 4) are formed by one continuous finite belt.

Abstract: A safety belt retractor comprises a housing containing first and second tandem spools for storing, respectively, lap and shoulder belts in helical wrap. Each of the spools is secured to a ratchet wheel engageable by a pawl located in the housing between the spools. Pawl support openings formed in opposite sidewalls of the housing enable the pawl to float while pivoting. In an equilibrium position, clearance between one end of the floating pawl and the first ratchet wheel is less than the clearance between the opposite end of the pawl and the second ratchet wheel. In response to acceleration of the vehicle carrying the retractor housing, a pendulum-type inertia device pivots the pawl from equilibrium into engagement with the first ratchet wheel. During pay out of the belts, with one end pivoting on the first ratchet wheel, the floating pawl is guided into contact with the second ratchet wheel by a cam surface defining one of the sidewall openings to positively lock the two spools.
