Abstract: ABSTRACT OF THE DISCLOSURE     Olefins such as propylene are oxidized directly to .alpha.,.beta.-unsaturated carboxylic acids such as acrylic acid with air or oxygen in an aqueous medium, employing an activated palladium-on-carbon catalyst, in the presence of a free radical inhibitor such as butylated hydroxytoluene.          The catalyst pretreatment consists of reducing it with propylene at temperatures of at least about 60°C for at least about 10 minutes in the substantial absence of oxygen.     In a like manner isobutylene may be oxidized to methacrylic acid, while butene-1 May be oxidized to crotonic acid.

Abstract: ABSTRACT OF THE INVENTION         The invention relates to a method of and an apparatus for transporting flexible foil packages, parti-cularly flat bags (6, 8, 13) filled with unstabilised material to a package container (1).   The flat bags (6, 8, 13) deposited flat and with uniformly distributed con-tents by a filling and closing machine upon a transport belt are first of all imbricated and maintained clamped on both sides during further transport into the package con-tainer, so that the uniform distribution of the contents is maintained into the container.   A close filling of the container (1) without excessive pressure is ensured by this means.   Because the flat bags are conveyed from the conveying path directly into the container without an intermediate magazine, containers of different size can be filled consecutively virtually without interrupting the conveyance.   It is therefore possible, in the case of parallel operation of a plurality of similar lines, to operate filling machines of different capacity each at maximum capacity, in order to assemble containers which are filled with the flat bags delivered by the different filling machines into larger assorted units, without the different capacity leading to an excess supply of con-tainers at the collecting station, where the containers are assembled to form the units.   The surplus capacity of one or the other machine is in fact compensated by locking in other package containers into the one line and subsequently withdrawing the filled containers.         Designated for publication:  Figure 1.

Abstract: ABSTRACT  OF THE DISCLOSURE                  METHOD FOR DESALTING CRUDE OIL      The salt content of crude oil is reduced by washing it with at least 1% by volume of wash water of lower salinity than the water present in the crude oil and separating the resulting mixture of oil and water into a layer of crude oil of reduced salt content and a layer of saline water containing some oil.  The latter is passed through a cross-flow membrane separator and the oil-free permeate is removed from the separator as effluent.  The oil retentate is recycled from the separator to the washing stage and a quantity of water of lower salinity than the water associated initially with the crude oil is added to the washing stage.  The quantity of added water corresponds at least to the volume of permeate removed from the cross-flow membrane separator.    Since the oil is recycled, the need for oil recovery plant for treating desalter effluent is removed.

Abstract: ABSTRACT OF THE DISCLOSURE    Shifting mechanism is provided for shifting gears in a gear box.  The gear box has a housing, a gear shaft in the housing, a plurality of gears on the shaft, a shift key movable along the shaft for individually connecting the gears to the shaft, a shift collar positioned around the shaft and engaged with the shift key, and a shift fork for moving the collar along the shaft.  The shift key moves along a longitudinal groove in the shaft and has a lug with an engaged or extended position extending radially outwardly from the groove and the shaft and a disengaged or retracted position in which the lug does not extend out of the groove.  The gears have bores through which the gear shaft extends so that the gears are rotatably supported on the shaft.  At least one of the gears has a plurality of uniformly spaced recesses or notches circumferentially located around the bore to receive the lug of the shift key so that the gear rotates with the shaft.  The recesses have ramps extending angularly in common directions from the bottoms of the recesses toward a common face of the gear.  The ramps force the shift key lug toward the retracted position when the key moves from one gear to another to prevent two gears from being engaged at the same time.  A neutral collar is rotatably supported in the gear shaft and receives the shift key lug when the gear box is in a neutral position.          The neutral collar has two oppositely-facing ramps to force the lug toward the retracted position when the shift key is moved in either direction from neutral.

The insert cartridge has means thereon for dispensing individual inserts one at a time and can be adapted to be held and mover by robotic arm or a reciprocal moving holder.  A toolholder having an insert pocket with a movable insert seat therein is utilized with the insert cartridge.  A reciprocably movable draw-bar moves the insert seat in the toolholder pocket back and forth so as to clamp and unclamp a cutting insert. When it is signaled to change the insert, the drawbar moves the insert seat out of the insert pocket, thereby unclamping the insert.  The insert is then removed from the insert seat and the insert storage cartridge is positioned in proper alignment with the toolholder.  The cartridge and toolholder are then engaged so that the insert seat engages the dispensing means on the car-tridge unit.  The drawbar is then actuated so that the insert seat is moved inwardly into the pocket of the toolholder, thereby taking an insert from the storage chamber of the insert cartridge and clamping it in the insert pocket of the toolholder.  The toolholder and the insert cartridge are thereby disengaged and the robotic arm on the insert cartridge may move it back to storage position so that machining may continue.
