Abstract: ABSTRACT PRESSURISABLE CONTAINERS          A valve cup (60) for an aerosol dispensing can has a side wall (68) of lesser girth at the bottom than in an upper zone of which a portion is adapted to intensify the seal in the swaged seam between the cup curl (70') and the body curl (22). The side wall has for example a step (88) which acts as a fulcrum.  In the swaged seam the seal is intensifed in the area adjacent the step and down to a second point of contact where the side wall is deformed by the swaging tool (38) into contact with the body wall (1).

Title: Optimization apparatus and procedure
Inventor: COLLINS JOHN B
IPC: G01N21/73

Granted: 1990-07-10
Abstract: Abstract A method and apparatus to optimize a characteristic of measured data in an adjusable instrument for chemical analysis. The characteristic is measured at a plurality of adjustment points about a start point. Through parabolic interpolation of the data a conjugate vector is formed and the best operating point thereon is selected. Then measurements of the characteristic are taken as a function of the adjustable parameters about the best point on the conjugate vector. These data are used in a parabolic interpolation to define a second conjugate vector. The best operating point on the second conjugate vector is the optimum point of the instrument.

Title: Bottle duster
Inventor: MCBRADY WILLIAM J
IPC: B08B5/02
Filed: 1986-07-03
Granted: 1991-03-05
Abstract: ABSTRACT     A device for removing dust and other fine particulate matter from the exterior surface of a bottle moving along a conveyor line.  A jet of ionized air neutralizes any static charge adhering the particulate matter to the bottle and also commences the dislodgement of the former from the latter.  Moving brushes contacting the exterior surface of the bottle further dislodges the particulate matter.  Last-ly, a vacuum on the other side of the brushes from the bottle removes the air and entrained particulate matter detached from the bottles.  A star wheel having indentations in it moves the bottles along at a predetermined pace.          Alternately, one or more  rotating longitudinal screws can control the bottles motion through the system.  A belt in contact with the bottles and moving relative to the conveyor effects their rotation regardless of their exterior config-uration. This assures that the brushes contact all portions of their exterior surface.   The star wheel has rollers attached to it which maintain the belt in an extended con-figuration and keeps it in intimate contact with the bottles.  When the device utilizes a longitudinal screw, the belt can rotate around rollers placed at the ends of the screw.

Abstract: ADAPTIVE METHOD AND APPARATUS FOR CODING SPEECH     ABSTRACT:     In a  speech coding  system,  scale  factors  are generated and encoded for each of a plurality of subbands of a Fourier transform spectrum of speech.  Based on those scale factors, the spectrum is equalized.  Coefficients of a limited number of subbands determined by the scale factors are encoded.  The number of bits used to encode each coefficient of each transmitted subband is determined by the scale factor for each subband.  At the receiver, coefficients of subbands which are not transmitted are approximated by means of a list replication technique.

Abstract: JET KNIFE STRUCTURE            Abstract of the Disclosure A jet-knife assembly for meats or like products is provided which assures even, predict-able grinding with a minimum of objectionable fines or agglomerated strings,  so as to yield final products of consistent dimensions and characteris-tics.  The overall assembly preferably includes a plate presenting only a single set of circularly arrayed apertures therethrough, together with a cooperating, multiple-blade,  rotating knife adja-cent the plate; the knife blades each have elon-gated fluid-conveying channels along the operating faces thereof, which are sized relative to the plate apertures so that the cross-sectional area of the channel is always greater than the total plate open area in communication with the channel during blade rotation.   Pressurized steam or air is di-rected to the blade channels during operations, so that as the knife rotates and blade channels come into communication with the plate apertures, prod-uct is expelled or "popped" out of the plate aper-tures.   Provision of non-bridging blade channels assures substantially constant pressure conditions at each plate aperture to yield the most consistent final products.

Abstract: ABSTRACT OF THE DISCLOSURE   In a document feeder with a vacuum belt platen transport system for transporting document sheets over the platen of a copier under a white vacuum plenum backing surface closely overlying the platen and into a registration position for imaging the document sheet, with a registration system for stopping the document sheet at the registration position. the platen transport system including a vacuum source for applying a partial vacuum to a document sheet being transported sufficient to provide transport of the document sheet with movement of the belt transport into the registration system, and a system for automatically reducing the level of the partial vacuum in the vacuum plenum sufficiently to allow slippage of a document sheet relative to the belt transport at the registration system and to avoid damage to the document sheet by the registration system; the improvement comprising a system for prior detection of a document sheet of greater than a predetermined size to be registered by the registration system. The vacuum belt platen transport system preferably comprises plural unapertured spaced-apart moving belts between which the partial vacuum is applied, wherein the partial vacuum level is automatically reduced to less than approximately 8 millimeters of water in response to the system for prior detection of a document sheet of greater than a predetermined size, and wherein the belts continue to move after the document sheet is stopped at the registration position by the registration system with slippage between the belts and the document sheet, and wherein the partial vacuum level is so automatically reduced after the partial transporting of the document sheet over the platen of the copier but prior to the transporting of a document sheet of greater than the predetermined size into the registration system.

Abstract: MULTI-AXIS ECM MACHINE USEFUL FOR    MACHINING AIRFOILS OF ROTORS            Abstract of the Disclosure A six axis ECM machine is provided for electrochemically machining the airfoil blades of an integrally bladed rotor of a gas turbine engine.  The cathodes of the machine each move along two different sets of axes, a right X-axis and Y-axis and left X-axis and Y-axis, relative to a workpart machining position in the electrolyte chamber while the rotor is moved vertically along a Z-axis.  The rotor is indexable about a sixth horizontal axis to present individual airfoil blades for machining at the workpart machining position.  The rotor is fixed on the Z-axis slide with its lateral center plane at an angle relative to the cathodes at the workpart machining position and the cathodes have recessed pockets to receive airfoil blades immediately adjacent the individual blade being machined as the individual blade is positioned at the workpart machining position.  These features of the machine provide full access of the cathodes to the blade to ECM the sides, leading and trailing edges, fillet radii and platform of the blade.
