Abstract: Abstract                                       C-I-L 635 Non-Electric Delay Blasting Method A non-electric delay blasting method is provided which comprises the use of single trunk line of detonating cord having a series of detonating relays,  all of the same delay period, connected at spaced intervals along its length. Branch lines of detonating cord are connected in groups to the trunk line in the intervals between the relays and each branch line has a delay detonator of the same delay period attached thereto.  The delay period of the relays is shorter than that of the delay detonators.  The detonators within the groups detonate in a random manner.  The method eliminates the need to use large numbers of different delay period detonators in a multi-charge blast thus simplifying prepara-tion of the charge and reducing inventories.

Abstract: ABSTRACT OF THE DISCLOSURE       The invention includes a process wherein an olefin is carbonyl-ated with carbon monoxide to form carboxylic acid esters in the presence of a catalyst complex of one mole of BF3 and one mole of alcohol, and the catalyst is recovered from the desired reaction product and the reaction by-products and is recycled. The car-bonylation is carried out until approximately one-half of the alcohol is consumed to form a reaction mass containing the BF3, the alcohol, and carboxylic acid esters in a 2:1:1 molar ratio . In the first step, the one mole of free BF3 is vaporized from the reaction mass. The remaining admixture is a 1:1:1 mixture of the aforesaid com-pounds. To this mixture additional alcohol is added and the mixture is subjected to distillation. An azeotrope of the product carboxylic acid ester and the alcohol and residual alcohol are removed by the distillation, leaving a residue containing a 1:2 BF3/ alcohol complex and the by-product carboxylic acid esters, which are heavier than the product carboxylic acid ester. The by-products are removed from the residue via solvent extraction and the remaining complex may be combined with an additional mole of BF3 to form the 1:1:1 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 recon-stituted catalyst is then preferably recycled to the carbonylation reaction. The carboxylic acid ester/alcohol mixture may be separat-ed 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: ARTICLE CAPABLE OF CREATING A MOIRE EFFECT Abstract of the Disclosure An article, illustratively a lamp bulb envelope, for creating a moire effect has a plurality of transparent and nontransparent regions on its surface.  When viewed from a point external to the envelope, the individual nontransparent regions on the surface of the envelope which is nearest to the point appear as superimposed upon and intersecting with nontransparent regions on the surface furtherest from the point.  The apparent intersections produce a moire effect which is enhanced by varying the line of sight to the bulb.  The family of moire curves appear as transversly running curves which pass through the points of apparent intersection of individual nontransparent regions along the near and far faces.          The nontransparent regions may be either light diffusive (translucent) or light nontransmissive (opaque) in nature and may be created by abrading the surface of the envelope or by application of opaque or diffusive coatings onto the surface of the envelope.  When an actual filament, arranged within the envelope, is energized to emit light, an apparent filament appears in inverted relationship with the actual filament within the envelope.

An operating bar pivotally supported by the main body of the riveter has one end pivoted to a chuck for gripping the mandrel and the other end serving as an engaging portion.  A pusher is pivoted to the movable handlebar and has grooved portions engageable with the engaging portion.  A bearing member pivoted to the main body is formed with bearing grooves positioned alongside the grooved portions in corresponding relation thereto and engageable with the engaging portion.  When the movable handlebar is repeatedly turned, the pusher pushes engaging portion in engagement with one grooved portion after another to engage the engaging portion correspondingly in one bearing groove after another and move the chuck by resulting movement of the operating bar for setting the rivet.

Abstract: ABSTRACT OF THE DISCLOSURE  A environmentally sealed snap action switch mechanism suitable for use in high temperature (900° F+) environments comprises a casing having a flex area formed on one surface so as to be susceptible to snap-action movement.  A switch is situated inside the casing.  An inner actuator leaf affixed at one end to the flex area links the latter with the switch.          An outer actuator leaf is affixed to the flex area on the outside of the casing.  The outer and inner actuator leaves move in concert to open and close the switch and cause the flex area to snap between normal and actuated conditions.  To ensure proper performance at high temperatures, a helper leaf spring extends between the outer actuator arm and the exterior surface of the casing to bias the outer actuator arm away from the casing.  Preferably, the switch includes a flexible steel blade, and, in one version, includes a two-layer blade to achieve extended switch life.

Abstract: ABSTRACT         The invention is concerned with a method of and an apparatus for applying a coating of solder to a metallised margin of a vitreous sheet.  The method of the invention is characterized in that an excess of molten solder is supplied along the sheet margin and in that the thus supplied solder is treated while molten with a doctor knife so that excess quantities of molten solder are continuously directed towards and over the edge of the sheet.  This method is carried out in an apparatus comprising a support defining a predetermined locus for the vitreous sheet;  means for supply-ing an excess of molten solder along a margin of the sheet carried by the support; means for effecting relative movement between the sheet carried by the support and such solder supply means, and a doctor knife associated with the solder supply means and arranged so as to direct continuously excess quanti-ties of molten solder towards and over the edge of the sheet, The invention finds use in particular in the field of multiple glazing panels in which vitreous sheets may be soldered directly to one another at their margins or in which vitreous sheets are held spaced apart by intervening metallic spacer members soldered to the metallised and solder coated margins of the sheets.

The catheter takes the form of a tubular sheath of thin elastic material having a cylindrical body section, a tapered neck section extending therefrom, and a reduced drainage tube section projecting from the neck section.  Within the sheath, and constituting an unitary  part thereof, is a tubular inner sleeve of soft elastic material having a distal end portion disposed within the neck section and a proximal end portion merging with the sheath's cylindrical body section.  The sleeve tapers distally to define an annular space thereabout, and terminates in a reduced distal opening located at an intermediate point within the neck section.  The sheath is produced by a dipping process that includes the preliminary step of stretching a pre-formed tubular member (which ultimately forms the inner sleeve) over a dipping form, followed by successive dipping steps.
