Abstract: A process is disclosed for producing TiO.sub.2 pigment which is substantially improved for use in electrophoretic coating compositions. The process comprises adjusting an aqueous slurry of the pigment to a pH of about 6.5-7.5, maintaining such pH at a temperature and for a time which is sufficient to maintain substantial equilibrium, and washing the pigment. There also is disclosed TiO.sub.2 pigment which is produced by the foregoing process.

Abstract: A fluid power control valve apparatus is disclosed and is characterized by combining desirable features of both a spool type valve element and a poppet type valve element. A spool element is provided with one end adapted to be seated in a poppet valve seat provided in the bore in which the spool is slideably mounted. The poppet seat is located in the bore between two flow ports. The poppet end of the spool engages and becomes fully seated only after the spool has passed a bore position closing one of the ports to operative flow and operates to seal the bore from the conventional leakage flow associated with spool elements. Also disclosed is a method of manufacturing such an apparatus in a two piece assembly to greatly simplify manufacture of a precise poppet seat within the spool bore.

Abstract: Continuous thermal treatment for the strengthening of metallic workpieces is carried out by placing a batch of at least two workpieces on a basket hinged on a continuously advancing conveyor chain; introducing said workpieces in said basket through a first instantaneously opening and closing gate into a uniformly heated first thermal treating step wherein the continuously advancing workpieces are heated at a temperature of about 560.degree. C.; introducing the heated workpieces in said basket through a second instantaneously opening and closing gate into a second thermal treatment step placed immediately after the end of the first step and in communication therewith, by lifting a vat containing a cooling fluid to immerse said workpieces in said basket into the cooling fluid of said vat to rapidly cooling said workpieces to a temperature of about 100.degree. C. and thereafter lowering said vat.

Abstract: A plating bath and process for electroplating coatings of palladium nickel alloys on a conductive substrate at current densities in the range of 10 amps/sq. ft. to 150 amps/sq. ft. wherein the palladium content of the alloy remains substantially constant despite current density variations during plating. The alloy composition stability is achieved by adding at least about 15 parts per million of iodate ions to the plating bath.

Abstract: First and second annular interengaging parts releasably connect the pouch and adhesive-backed label. A member is provided for mounting one of the parts to the label, at a normal position proximate the surface of the label. The member includes a ring-shaped section, spaced from the part, which is adapted to be affixed to the surface of the label, and an expandable section, preferably including one or more accordion-like folds, interposed between the ring-shaped section and the part, to permit the part to be displaced relative to its normal position. The member will return to its normal position unless a detachable element is inserted beneath the member to retain the part in the displaced position. The other interengaging part may be provided with a flange-like portion situated to cover the expandable section, when the parts interengage, to protect the expandable section from waste material. Auxiliary interengaging parts may be provided to prevent accidental detachment and aid in supporting the pouch.

Abstract: This invention relates to certain pyrazole sulfonylurea herbicidal compounds, agriculturally suitable compositions thereof and a method of their use.

Abstract: This invention involves unique compositions consisting of substrates coated with organo-silanes that are sterically protected by a single bulky group. This material consists of an appropriate reactive solid to which is attached a silane whose silicon stom is bonded to a functional group that contains a dimethyl-substituted tertiary carbon.

Abstract: The invention relates to a sieve for a paper pulp scrubber or similar equipment, and to a method for fabricating such a sieve. The sieve is produced by mechanical interfit of bars with support members, the bars carrying notches, the lips of which engage at least one V-shaped lateral groove formed in each support member, while the support members present, on their face receiving the bars, a first set of notches for positioning the bars. The cross-section of the support members at the level of the first notches has the same configuration and dimensions as the cross-section of the second notches and the cross-section of bars at the level of notches has the same configuration as the cross-section of notches formed in the support members. Assembling is made by bending a bar by an angle of about 20-25.degree. for widening a second notch and inserting a support member therein. The bar is then straightened back, so that the support member will be firmly clamped in the notch.

Abstract: Novel N-(heterocyclicaminocarbonyl) substituted thiophene- , furan- and pyrrolesulfonamides, such as N-[(4-methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]-6,7-dihydro-5H-thieno- [3,2-b]thiopyran-3-sulfonamide. 4,4-dioxide and N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-6,7-dihydro-5H-thieno[3,2-b ]thiopyran-3-sulfonamide, 4,4-dioxide and their method-of-use as herbicides are described.

The sodium carbonate that forms in the absorption is not removed prior to crystallization.

Abstract: An apparatus for mating a structural element to a pair of frame members. The mating apparatus includes a stud carried by the element, a pin carried by each of the frame members, a brace positioned, during mating, so that inwardly turned portions formed at each lateral end of the brace engage a corresponding pin carried by the frame members. Structure is provided to urge the brace progressively closer to the structural element. As this urging occurs, the pins carried by the frame members are driven toward the structural element by the corresponding associated inwardly turned portions of the braces until the pins can be urged no farther. As this occurs, tightening of the frame members to the structural element occurs.

Abstract: A vehicle dash mounting device for mounting at least one accessory to a top surface of a vehicle dash includes a housing for mounting to the top surface of the vehicle dash with an upper housing surface and hook and eye fabric fasteners for detachably securing the accessory to the upper housing surface. The housing is also detachably mounted to the dash by hook and eye fabric fasteners. Additionally, for vehicles with a defroster-type vent in the dash, a hook is mounted to the upper housing surface to engage the vent. The housing is generally of a wedge shape, tapering with the downwardly sloping top surface of the dash to position the upper housing surface in a substantially horizontal plane. For accessories with bottom mounted speakers, such as some CB radios, the upper housing surface has an aperture beneath the radio, and the front face also has one or more apertures to allow sound from the speaker to be heard within the vehicle passenger compartment.

Abstract: A safety device for a tool powered by an electric motor. It has a main switch, electronic controls, and a tachometer-generator. In order to provide a device for switching off a motor as a function of motor speed that is simple and economical and that will retain the same nominal switch-off value for the total life of the device, a relay is wired in parallel with the motor and controls the supply of power to the motor through a relay contact.
