Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for forming a seal between layers of a carton of thermoplastic coated paperboard material and the like wherein the thermoplastic material in the area to be sealed serves as the sealant and is activated to flow by frictional heat generated by a vibration welding horn and is then allowed to cool and set under pressure to form the seal between the layers.  The carton first moves to an activating station wherein the layers to be sealed are engaged on opposite surfaces by a vibrating horn and a back-up member (in the form of an anvil or a mandrel) for a time suf-ficient to activate the thermoplastic material to flow.  The car-ton is then carried to a clamping and sealing station at a dif-ferent location from the activating station with the thermoplastic material in the activated state.  The layers to be sealed with the activated thermoplastic is then engaged on opposite surfaces by a pressure pad and the back-up member for a predetermined period of time to permit the activated thermoplastic to cool and set and form a seal.  A holding member extends between the activating and clamping and sealing stations.  The holding member overlies the back-up member for engaging the outer surface of the layers to hold the layers together in cooperation with the back-up member when the carton is located at either of the stations or between the stations.  The holding member is slotted to permit the horn and pressure pad to engage the outer surface of the layers while the layers are held in the closed position between the holding member and back-up member.

Abstract: ABSTRACT OF THE DISCLOSURE   An improved inertially locking hinge for vehicular seats which permits the seat back to be pivoted downwardly when the vehicle is not subjected to inertial forces but which, under the influence of selected inertial forces, causes a simple metal block element to pivot into engagement with ratchet teeth on the movable of the hinge elements. Weight and space savings are achieved by using a small thrust carrying block element secured in a plastic case and the case is pivotal in a slightly arcuate opening and the case enclosing a mass positioned to act between parallel spaced-apart fixed plates, the plates pivotally supporting the principal hinge point and seat back support. The block element carries the thrust of the teeth into the fixed plates at a buttress at the arcuate opening.

Abstract: WET ADHESIVE EMULSIONS FOR PAINTS AND COATING COMPOSITIONS ABSTRACT OF THE DISCLOSURE Improved wet adhesion properties of water-based paints and coating compositions are obtained by incorporating into the polymeric resin emulsion systems employed in the formulation of such paints or coating compositions a monomeric compound having a terminal ureido group at one end thereof and a vinyl terminal group at the opposite end. Such incorporated monomeric compounds correspond to the general formula wherein R is H or CH3, U designates a cyclic or acyclic ureido or thioureido group and L designates a selected linking structure.. In the simplest of such monomeric compounds, L is -CH2-, as specifically represented by allyl urea. In other representative compounds the linking group L may be a polymethylene group -(CH2)n- or the chain may contain one or more oxy (ether), anino, amido or carbonyl groups, provided that any carbonyl group (CO) present is not directly attached to U or to an ethylenic carbon atom nor is such ethylenic carbon directly attached to a nitrogen atom. Among preferred monomeric compounds imparting such improved wet adhesion are: N-5eta-allylaminoethyl ethylene ures, allyloxy N-3-(1-ethylene ureido) ethyl acetamide, and allyl ester of N-ethyl-3-(l-ethylen ureido)-N-methyl carbamate. The polymer resin in the emulsion is one formed from one or more ethylenically unsaturated monomer compounds, such as acrylates and methacrylates vinyl esters, vinyl chloride, mono- or di-ethylenic hydrocarbons; or copolymers, interpolymers or blends of these.

Abstract: ABSTRACT This invention relates to a method for stabilizing an aqueous, peroxide-containing composition and to the resulting stabilized composition.  In using an aqueous formula containing hydrogen peroxide or urea peroxide, used for example in treating the roots of plants, a problem of stability or lack of suitable shelf life has developed.  That is, over a period of time, aqueous solutions of the composition tend to prematurely decompose chemically or by release of oxygen.  The present invention pro-vides a method of stabilizing an aqueous, peroxide-containing composition comprising stabilizing the composition with a stabilizing amount of lignon sulfonate.  It has also been dis-covered that the stabilizing effect of lignin sulfonate is en-hanced by the use of EDTA and is further enhanced by the use of a nontoxic magnesium salt.

Abstract: Abstract of the Disclosure An array camera used to scan elongated workpieces moving through a measuring zone transversely to their lengths has its photoresponsive detector elements aligned lengthwise of the workpieces, with optical axes of the elements lying in a common plane intersecting the measuring zone.  Each element "sees" only a small (e.g., 8 x 8 mm) pixel.  Radiation sources are located at opposite sides of said plane and emit radiation towards the measuring zone to be reflected to the elements from workpieces.  During each of a succession of short measuring cycles (e.g., 4 millisecond duration)  each element is exposed successively to radiation originating from each radiation source to the exclusion of the other, to thus produce an A output and a B output during each cycle, and is also exposed to sub-stantially low level radiation to produce an R output.          For each cycle, the R output of at least certain elements is subtracted from the A and the B outputs of the same elements for the same cycle, to produce ? A and ? B difference signals.  Timing is such that ? A and ? B signals for the same element and cycle originate from one and the same small surface area on the workpiece, and therefore inclination of that surface area is ascertainable as a function of the ? A and ? B values.  During a fourth interval in each cycle, certain elements detect radiation from a laser that has its beam in said plane and oblique to the workpiece surface, and such elements then produce an L output.  From the particular elements that produce L outputs, local thickness of the workpiece is ascertainable.

Abstract: Turning Mechanism for the Feed of a Drilling Machine, Especially  a Rock Drill Abstract of the Disclosure This invention relates to a turning mechanism for the feed of a drilling machine, especially a rock drill.  The mechanism comprises a first hydraulic cylinder with a piston and a piston rod to turn the feed round an axle which is transversal to the longitudinal axis of the feed, i.e. to the drilling direction.  It also comprises a directional control valve to control the first cylinder, a second hydraulic control with a piston to turn the feed, a directional control valve to control the second cylinder and a hydraulic pressure source.  The second hydraulic cylinder is coupled parallel to the first cylinder so that the stroke of the piston of the second cylinder by means of the stroke of the piston of the first cylinder causes a look-out angle for the feed which is determined by the stroke of the piston of the second cylinder.
