Abstract: ABSTRACT OF THE INVENTION     An apparatus and method for the electroless plating of articles.  A tank is provided for sequentially containing the respective constituent baths corresponding to the steps of the electroless plating process.  An article to be plated, such as a printed circuit board, is supported in the center of the tank immersed in the constituent bath contained therein.  A pair of inwardly facing parallel manifolds are disposed at opposite ends of the tank.  The constituent solution is pumped through a nozzle matrix in the inward facing wall of a first manifold onto the article and is simultaneously sucked away from the opposing side of the article through the matrix of the nozzles defined in the inward facing wall of a second manifold.  The direction of pumping is alternated for periodically reversing the direction of suction and impingement. The alternating pressure difference created across the surface of the article being plated substantially improves the rate of metal deposition over prior art systems and allows for a uniform and high quality plate over the entire surface of the article.  Additionally, through-holes defined in the article are thoroughly and uniformly deposited with electroless metal.

Abstract: OPTICAL FIBER CENTERING DEVICE                 Abstract of the Disclosure A centering device holds an optical fiber along an axis with three fiber receiving sections and a receiving member.  The receiving member has a concentric cylindrical cavity for holding assembled sections.  Each section, substantially identical, has a uniform cross-sectional configuration at right angles along a major portion of its length forming a boundary of fixed perimeter.   One boundary portion of one section contacts another section. Another boundary portion contacts a different section. third portion contiguous to the first two portions is adapted to engage an optical fiber along its length.  A fourth portion contiguous to the first two, but not to the, third,  engages  the cylindrical wall defined by the concentric cavity.  The cavity terminates with an axially oriented truncated conical recess.  The fourth portion of the boundary engages differing amounts of a cylindrical wall depending upon the shape of the fourth portion. The sections  include  elastomeric material of  sufficient resilience for a passageway defined by the third portions of assembled sections to expandably receive an optical fiber dimensioned  larger  than the passageway.   The passageway  can  have  a  substantially  triangular cross-section for receiving a fiber having a substantially circular cross-section.  It can flare outwardly from a position interior the fiber receiving means to respective ends thereof.  Passageway flaring can have various shaped configuration.   The  assembled  three  fiber receiving sections can have a polygonal shaped external surface. The receiving member can be transparent.   The fiber receiving sections can be held within the cavity of the member by a force fit.  The radius of the three sections, when assembled but prior to insertion into the cavity, is greater than the radius of the cavity. Thus, an inserted fiber is guided smoothly along a wall of the recess and is stopped when the cross-sectional dimensions of the recess no longer is greater than the diameter of the inserted fiber.  Desirably, the end of the fiber is positioned at the focal point of the receiving member.

Abstract: An apparatus as disclosed for controlling the distribution of fibers in a fiber felt forming process, which comprises a guide duct through which a gas current with felt fibers entrained is directed. The gas passes through a perforated conveyor, which retains the fibers. The duct is caused to oscillate by a connecting rod affixed to the guide duct and a rotary element by universal joints at either end, connection being effected by cardans, by which the rotary element entrains the connecting rod in its rotary movement. By moving the axis of rotation of the rotary element away from the center of the guide duct/connecting rod joint, an oscillating movement is imparted to the guide duct. The entire apparatus, including a motor for inducing rotary movement may be caused to undergo translational movement by a pair of opposed hydraulic jacks, the operation of which may alter the median direction of the movement of the oscillating guide duct. The apparatus as disclosed provides for automated movement and correction during operation of the device, providing better control over the distribution of fibers.

Abstract: ABSTRACT OF THE INVENTION         An improved, explosively embedded anchor assembly for use in sedimentary strata and similarly nonconsolidated or rocky ocean bottom surfaces is shown.   The anchor provides, through improved design for secure holding within relatively soft bottom strata. In addition, is provides accurate posi-tioning, as is required for mooring points for moored buoyant and semi-submersible vessels, as are encountered within oil drilling and the like offshore.       The anchor comprises an  inertially loaded reaction member  above  a  substantially  elongated  anchor  shaft, coaxially positioned around an elongated drive tube assembly.          The  anchor  shaft  has  a  number  of  open  cross-section triangular sheet metal anchoring fins, providing substantially low  resistance  to  penetration  within  the  strata,  but providing  substantially   high   resistance   to   sideways displacement forces, as would be imposed through a standard anchor  rode.    The  anchor  is  positioned  by  lowering  the inertial reaction unit and embedded by the weight of  the inertial reaction unit a distance into the surface layer of the subocean strata.  An internal detonator control assures vertical embedment of the anchor and prohibits firing of the explosive  for  embedment  unless  the  anchor  is  vertically positioned.    The  anchor  is  remotely  fired  after  initial embedment.   The particular explosive has a relatively low velocity explosive wave, and jets the anchor shaft downward from around the drive tube, providing a substantially deep subsurface embedment.   The combination of relatively long drive  period,  low  embedment  velocity,  the  substantially elongated drive contact between the reaction member and the anchor member, and the substantially elongated dimensions of the  anchor  member  provide  a  well  secured  accurately positioned, explosively embedded anchor as is required for an accurate, deep sea anchoring array.

Abstract: La solution adoptée à ce jour pour réduire l'encombrement de certains fusils et carabines sans modiication permanente de ces armes consiste à remplacer la crosse de bois d'origine par un kit composé d'une poignée-pistolet fixée à l'arrière du pontet et completée par une mince crosse métallique que l'on replie pour le transport et/ou le tir à la hanche. Au nombre des inconvénients de ce système on note un mauvais équilibre de l'arme lorsque la crosse est repliée, un recul plus sensible lors du tir à l'épaule avec la crosse déployée et la nécessité d'une série de manoeuvres pour passer de l'une de ces positions à l'autre. La présente invention permet d'éliminer la crosse pliante qui se trouve remplacée par une mini-crosse rigide fixée à l'arrière de la carcasse de l'arme. Une poignée-pistolet dotée de son propre mécanisme de détente est installée dans une position avancée de manière à répartir le poids de l'arme de part et d'autre de ladite poignéepistolet. Cette disposition confère à l'ensemble une compacité égale ou supérieure à celle des systèmes ordinaires en position "crosse repliée", un excellent équilibre, un recul atténué au tir épaulé et le passage instantané de la position "transport/tir à la hanche" à la position "tir épaule" et vice-versa.
