Title: Method for lofting blanks and compounding plates for shell structures
Inventor: LETCHER JOHN S JR
IPC: G05B19/41
Filed: 1989-06-27
Granted: 1993-02-23
Abstract: METHOD FOR LOFTING BLANKS AND COMPOUNDING PLATES               FOR SHELL STRUCTURES          Abstract Methods for lofting flat metal starting blanks and for compounding curved metal plates from the flat starting blanks can be used in lofting and fabricating boat hulls, aircraft and automobile bodies, tanks, containment vessels, and other shell structures.  The methods relate starting blanks and compounded plates to specified patches of a defined surface having compound curvature, or more precisely, non-zero Gaussian curvature.  The surface is a representation of the shell structure to be fabricated by assembling the plates.  In each of the methods the in-plane strain is related to intrinsic geometry in a strain equation.  The strain is explicitly or implicitly considered and solved for accurate and controlled implementation of both the lofting and cutting of the blanks and the compounding of the blank into the desired plate configuration.  Solution of the strain equations for boundary nodes in the plane of the blank for cutting the blank minimizes field trim.  Solution of the strain equations for strain distribution in the plane of the blank provides the guidance necessary for controlled introduction of strain through application of controlled compounding processes.  Automated control may also be implemented by thickness monitoring at the nodal coordinates during compounding.  Each of the methods of the present invention involves solution of the strains in a differential geometric mapping from one parametric surface manifold to another explicitly or implicitly reflecting the in-plane strain involved in compounding.

Title: Fitting socket with integral reinforcing ring
Inventor: VALLS JOSE E
IPC: F16L19/00
Filed: 1989-07-28
Granted: 1993-06-22
Abstract: ABSTRACT OF THE DISCLOSURE    A socket construction is provided for a fitting having a body of a first, smaller diameter and a forward end.  The socket construction  includes  an enlarged,  cylindrical  socket of  a second, larger diameter.  The socket is integrally formed of the same material as the fitting and is defined by a cylindrical sidewall.  The sidewall has an inner cylindrical periphery and an outer cylindrical periphery, the outer cylindrical periphery of the socket being of uniform diameter.  The sidewall terminates forwardly at the forward end of the fitting in a sidewall front end terminus for receiving a spigot end of an adjoining member.          A rear end terminus of the socket is spaced rearwardly from the front end terminus.  A lip is also provided, which is integral with the socket, and which extends radially inwardly from the front end terminus to define a gasket pocket with the inner cylindrical periphery.  The construction includes an inelastic, integral, non-helical, closed reinforcing ring extending radially outwardly from the outer periphery of the socket sidewall for increasing the resistance of the sidewall to fracture upon insertion of the spigot end.  The reinforcing ring has an outer periphery that is greater than the outer periphery of the socket sidewall.   The reinforcing ring is spaced forwardly from the sidewall rear end terminus.

Title: Self regulating temperature heater with thermally conductive extensions
Inventor: HENSCHEN HOMER E
IPC: B23K1/002
Filed: 1989-09-25
Granted: 1992-11-10
Abstract: ABSTRACT    Spaced contact pads on a printed  circuit board are soldered to respective  spaced contacts in  a cable  or connector assembly  by means  of  respective  spaced connecting members  interposed between  contacts to  be soldered.   The  connecting  members  are  typically electrically  and  thermally  conductive  finger-like projections formed as  part of a  heater body and are readily severable from the heater body after soldering to thereby remain part of  the final solder connection.   A prescribed amount of fusible material  (e.g., solder) is pre-deposited on the connecting members or contacts and is melted when the heater is actuated.  The heater body  may be a self-regulating  heater in the  form of  a copper substrate having a  thin surface layer  of magnetically permeable, high resistance alloy.  An alternating current of constant amplitude and high frequency is passed through the heater body and is concentrated in the surface  layer at temperatures below the surface layer Curie temperature.          At higher temperatures the current is distributed through the lower resistance substrate to limit further  heating.          During the time interval required for the surface layer to reach its  Curie  temperature,  the  resistive  power dissipation creates sufficient thermal energy to melt the pre-deposited solder.   The  connecting  members  are positioned and configured  as necessary to  reach their respective connection sites.

Abstract: An improved hot air knife for use in removing excess solder from a circuit board in a mass soldering system of the type described in U.S. Patent Nos. 4410126 and 4401253 is described.  In the present invention the hot air knife comprises a commercially available square tube, one of whose edges has been cut to provide the air knife outlet.          Inside this tube, there is provided a second round tube for introducing hot air into the space between the round tube and the square tube.  This inner round tube has holes facing away from the outlet slit of the square tube, preferably at least 45 degrees on both sides of a plane extending from the outlet of the square tube to the opposite corner of the square tube.  In a preferred embodiment of the invention there is also provided at least one baffle in the volume between the outlet holes from the inner tube and the outlet slot for the air knife.          In a preferred invention, this baffle is in the form of a fairly fine screen (about 60 mesh) in the volume between the tube and the rear corner of the square tube.  Another such wire mesh can be provided on the other side of the space between the round and square tubes.    The "air knife" can also be used as a high pressure water Jet for cleaning surface mounted semiconductor elements carried by printed circuit boards.

Abstract: In a two-armed cutter bar (10) for a lawnmower with a vertically rotating shaft, the cutters (14) are fastened at each of the two ends by means of a respective single fastening bolt (36). The end portions of the cutter bar (10) have conical rotary guides (24), into which fit correspondingly conical rotary guides (38) of the cutter carrier plates (32). This ensures centering and rotary guidance. A positive junction between a rib (46) of the cutter carrier plate (32) and a bead (20) of the cutter bar (10) makes a positive connection which is broken under excessive stress when a stone or the like is struck, the result of this being that the cutter (14) can rotate. The positive connection can be broken in this way in the elastic or plastic range if the parts engaging in one another are resilient or if, for example when an expansion bolt is used, the length of the bolt is increased when excessive load occurs. <IMAGE>

Abstract: In each of packet switching nodes making up a packet switching netowrk, when it is desired to transfer a data packet between terminal and line interfaces, an identifier called an access channel number is attached to the data packet;  whereas,  when it is desired to transfer a data packet through multiplexing lines between line interfaces of adjacent packet switching nodes, an identifier called a transport channel number is attached to the data packet to specify the respective connections.  In particular, when a broadcasting packet communication is specified wherein a common packet is to be transferred from a packet terminal to a plurality of destination packet terminals at the same time,   the  access  channel  number  attached  to  the broadcasting packet to be transferred between the terminal and line interfaces is uniquely defined in the associated packet switching node; while the transport channel number attached  to the broadcasting packet to be transferred through the multiplexing line between the line interfaces is uniquely defined between the adjacent packet switching nodes,  so that the broadcasting packet is automatically branched  as transferred  into a plurality of  specified transfer destinations.
