Abstract: Abstract of the Disclosure Apparatus for turning pads through an angle of 90° about an axis perpendicular to their plane as they are orbited with a drum from a pad pickup station to a pad transfer station.  The drum has a plurality of circumferentially spaced apart supports inside of it.   A hollow shaft extends radially out of each support and has a vacuum pickup shoe on it.  A pinion is fastened concentrically to the hollow shaft and a gear in the support turns the pinion.  A cam follower engages in the groove of a stationary circular cam. As the drum rotates the cam follower arrives in a part of the cam groove which turns the gear and results in the hollow shaft and the vacuum shoe being turned through an angle of 90° as the shoe is orbited from the pad pickup station to the pad transfer station. Flexible tubes connect ports in the base of the drum to the hollow vacuum shaft.    The ports run over a curved groove in a stationary vacuum platen at times when vacuum must be applied to the shoe and run off of the groove and cut off the vacuum of the shoe at the pad transfer station where pads are transferred to a rotating vacuum drum.

Title: Method, system and composition for soldering by induction heating
Inventor: MCGAFFIGAN THOMAS H
IPC: H01R4/72
Filed: 1991-01-15
Abstract: This invention provides a method for soldering using induction heating, which is accomplished by the use of lossy heating particles in or on the solder and an alternating magnetic field. The lossy heating particles useful in this invention are magnetic particles, which can be ferromagnetic particles or ferrimagnetic particles, preferably ferrites, which have a Curie temperature at least equal to the flow temperature of the solder. These particles thereby provide a self-regulation feature which prevents overheating of the solder in the articles being soldered. The invention also discloses the use of particles with surface properties whereby the particles can either be wetted by the solder and remain in the solder when the solder flows or it can be nonwettable by the solder whereby the particles separate from the solder when the solder flows. This invention also discloses solder compositions, systems and assemblies utilizing the above combinations of solder and lossy heating particles.

Abstract: A B S T R A C T A new two-axis  accelerometer  comprising  an electric motor-driven rotating body that is distinct from the rotor motor and linked to latter via a flexure zone. The resulting rotating body/flexure zone combination may be of either of two types. In a first type the rotating mass is a concentrated mass and the flexure zone permits the rotating body to perform a transversal parallel shift. In a second type the rotating body is an inertia rotor and the flexure zone is an extension of the rotor shaft that embodies a flexible portion. In either type the rotating body/flexure zone combination has two degrees of flexing freedom with two different flexure coefficients in two mutually perpendicular directions both normal to the electric motor shaft. The accelerometer further comprises a deflector shaft coaxial with the rotor shaft and extending beyond the rotating body in a direction away from the electric motor,  and in association with said deflector shaft electro-optical measuring means and processor means for measuring linear acceleration components in said two mutually perpendicular directions. In one of its aspects the two axis accelerometer in accordance with the  invention measures only two perpendicular components of the acceleration of a body to which it is attached. By another aspect the two axis accelerometer according to the invention is a multisensor being at one and the same time a two-axis angular rate gyroscope and a two axis accelerometer. By yet another aspect of the invention there is provided a multisensor inertial  measurement  unit  (MIMU)  serving  for  the simultaneous measurement of three angular velocity and three linear acceleration components.     80955spc.MC/rg/3.7.1990

Abstract: ABSTRACT               (Summary of the invention) The present invention relates to a three position table for the purpose of holding three separate and individual working tools.          These tools, for example, could be; a combination belt and disk sander, a bench grinder, and a scroll saw. The table can be adapted to hold different types of machines similar to the above eg: drill press, lathe, router, edger, planer etc. Tools such as a table saw or a radial arm saw would not mormally be adapted, however, custom designing could be made.            The purpose of the table is to enable the Home Hobbyist (do it yourselfer) or Light Industrial User the opportunity to reduce the space necessary to accomodate various machine/tools while maintaining the ability to bring them into use, one at a time, speedily when required.     This three position revolving worktable provides each position as a sturdy shelf to which the tool is securely fashioned. As each shelf is brought up to the top position it is locked in place.          This allows the machine to be used without hinderence from the other two machines. When one of the other machines is required the shelf is unlocked, the table is rotated to bring the the desired machine to the top position, locked in place, and that machine is ready for use.            While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the form and details of the device is illustrated and in its operation can be made by those skilled in the art without departing from the spirit of the invention.
