Abstract: C-3077                                           D-3583 In a front-wheel-drive vehicle having a powertrain with a transversely positioned engine and transmission and independent front-wheel suspensions each with a control arm, there is provided a cradle to which the drive-wheel suspension control arms are swingably mounted.  A plurality of cushion mounts support the cradle at high impedance points on the vehicle body and provide a soft substantially linear spring rate at small vibratory amplitudes of the cradle in both a fore and aft direction and a vertical direction relative to the vehicle and a stiff substantially linear spring rate at all vibratory amplitudes of the cradle in a lateral direction relative to the vehicle.  The powertrain is directly supported on the cradle by a plurality of cushion mounts which have soft subtantially linear spring rates in the same directions as the cradle mounts. In addition, both the fore and aft rate and vertical rate of the cradle mounts and also the pitch rate of the powertrain mounts are controlled so as to be non-linear at large amplitudes of the cradle and powertrain in the respective directions. Furthermore, a rigid strut is cushion mounted between the powertrain and a mounting point on the vehicle so as to be in either tension or compression depending on whether the transmission is in forward or reverse drive. The strut mounts provide a soft substantially linear rate at small-amplitude powertrain pitch motions occurring at low powertrain torque and provide a non-linear rate at large-amplitude pitching motions occurring at high torque and cooperate with both the cradle mounts and the powertrain mounts to control and isolate pitching motions of the powertrain.

Abstract: ABSTRACT OF THE DISCLOSURE      Propylene and ethylene may be carbonylated to form car-boxylic acid esters or carboxylic acids in the presence of a catalyst complex containing 1 mole of BF3 and 1 mole of a second complexing component.  The carboxylic acid product or acid portion of the ester product has one more carbon atom than the olefin reacted.  High yields of these products are obtained.  In the case of the formation of the ester, the second complexing component is an alcohol, while in the case of the preparation of carboxylic acid, the second complexing component is water.  Methyl isobutyrate and methyl propionate formed by the carbonylation of propylene and ethylene, respec-tively, in the presence of a BF3.CH3OH catalyst may be de-hydrogenated to prepare methyl methacrylate and methyl acryl-ate, respectively.  Similarly, the isobutyric acid and pro-pionic acid formed from propylene and ethylene, respectively, in the presence of BF3.H2O catalyst may be dehydrogenated to prepare methacrylic acid and acrylic acid, respectively. In the case where the BF3 alcohol catalyst is used, it is readily recovered from the reaction product and recycled. After carbonylation is carried out and approximately one-half of the alcohol is consumed, a reaction mass containing the BF3, the alcohol, and the carboxylic acid ester in a 2:1:1 molar ratio is formed.  In the first recovery step, the one mole of the free BF3 is vaporized from the reaction mass.  The remaining admixture is a 1:1:1 mixture of the three aforesaid compounds.  To this mixture some additional alcohol may be added and the mixture is subjected to distil-lation.  A carboxylic acid ester/alcohol azeotrope and any residual alcohol are removed by the distillation, to leave a residue containing a 1:2 BF3/alcohol complex. This complex is combined with an additional mole of BF3 to form the 1:1 catalyst complex used in the carbonylation.  The additional mole of BF3 is preferably that initially separated from the reaction mass; however, it may be obtained from an external source.  The carboxylic acid ester/alcohol mixture may be separated by azeotropic distillation using an azeotroping agent, such as octane, to recover the alcohol-octane as overhead product and the carboxylic acid ester as bottoms product.

Abstract: ABSTRACT OF THE DISCLOSURE         A two-speed clutch in which an input rotary drive is transmitted to an output rotary member to produce a high speed direct drive in which the output rotary member is driven at the same speed as the input member, or to produce a reduced output speed.  The input member comprises an inner drum driven by centrifugally actuated clutch shoes in turn driven by an input shaft.          A second set of clutch shoes is interposed between the inner drum and the output member consisting of an outer drum, which clutch shoes are designed to be centrifugally disengaged to produce a controlled slip between the inner and outer drums to reduce the output speed.  In the high speed mode, the inner and outer drum, are latched together to rotate at the same speed by a pivotally mounted latch mounted on the outer drum and an expanding spring element mounted to the inner drum, with engagement between the latch and expanding spring taking place at a predetermined rate of rotation of the inner drum to establish high speed drive.  A trigger element is operable to release the latch and allow it to be centrifugally moved out of the path of the expanding spring precluding engagement of the latch with the expanding spring by energization of the trigger whenever low speed drive is to be established through the unit.

Abstract: ACCURATELY PLACED STRESS CONCENTRATING      APERTURE IN FLEXIBLE PACKAGES                   Arthur E. Frohwerk David E. Enting ABSTRACT An "easy open" feature for a sealed flexible pouch and method and apparatus for accurately position-ing said feature in the sealed border region of said flexible pouch.  The feature comprises a stress con-centrating aperture exhibiting a strong tendency to initiate a directional tear while maintaining integrity of the sealed pouch until an opening force is applied. In a preferred embodiment the pouches are cut from a moving web by a rotary shear cutter while a web punching means operatively connected with each cutter blade is engaged in the moving web.  Because the web undergoes no movement relative to the cutting means or the punching means until both operations have been completed the aperture is precisely positioned with respect to the severed edge of the pouch.  In a particularly preferred embodiment, the sealed edge of the pouch is subjected to a high level of tension and is unsupported in the area of contact with the punching means during the aperturing operation.  This concentrates the stress applied by the punching means and helps to form an aperture in the seal, even where tough and/or stretchy pouch materials which are prone to stretch and deform rather than rupture are employed.  While the precise shape of the aperture is not critical, it is preferably non-circular in order to provide at least one area of stress concentration within the aperture and thereby facilitate tearing at relatively low levels of applied stress.
