Title: Plastic or resin top construction for a dispensing can
Inventor: ADAMS JAY J
IPC: B65D51/22
Filed: 1987-07-15
Granted: 1991-01-08
Abstract: Abstract A foolproof sanitary pour type of end cap is provided for  a container or can  that may  be  used  for  providing  and dispensing powdered or granular  items, such as foods, vitamin and  medicine  capsules  or  liquids,  such  as  carbonated  soft drinks.   The   cap  body   provides   an   initial   completely hermetically  sealed cover  for  the  container  after  the  goods have been placed therein for shipment, storage and sale. The sealed relation is such that the inside of the container and its contents cannot be exposed without tearing-off a membrane closure  portion  across  a  centrally  disposed,  inset  pouring spout or  collar.  When the contents are to be first used,  a swingable closure lid is opened and the membrane is removed by a pull tab. However, the remaining contents can be then closed-off by the swingable lid which has means for maintaining the contents in a sealed-off relation from the ambient atmosphere and  has  latching means  for  flexibly  retaining  it  in closed position until an additional quantity of the contents is to be used.

Title: Coordinate measuring system
Inventor: MCDONALD GREGORY J
IPC: G01B21/04
Filed: 1987-12-09
Granted: 1992-04-28
Abstract: ABSTRACT    The coordinate measuring system comprises a device D and host computer 19.  The device D is formed of a base 1 rigidly attached to the article to be measured, an arm 2 rotatable relative to the base 1 only about axis A, arm 3 rotatable relative to arm 2 only about axis B, and arm 4 slidable relative to arm 3 along axis C.  The axes A, B ' and C are parallel to the extent obtainable by commercially desirable assembly techniques.  At the pivots 5 and 6 and sleeve 7 there are high precision bearings and rotary encoders.  At the sleeve 7 the rotary encoder is fixed within arm 3 and driven by a wheel frictionally engaging the surface of arm 4.     The rotary encoders provide information which indicates angular displacement of respectively the arms 2 and 3 about axes A and B relative to base 1 and arm 2 as well as the linear displacement of arm 4 along axis C relative to arm 3.  Based on the dimensions of arms 2 and 3 and the encoder derived measurements the approximate coordinates (inaccurate due to axes misalignment, flex of components etc.) can be calculated.  However computer 19 also has programmed into it after the assembly of device D a set of error terms so as to modify the mathematical transformation used in obtaining the coordinates and produces accurate coordinates.  The error terms are obtained by a computerized Error Correction Procedure which compares a number of known coordinate values with the coordinates as measured by the system.

The separation threshold values are determined on the basis of measured values of the predetermined particle parameter arranged in individual histograms containing at least two particle population maxima and minima.  At least one particle population minimum is determined using an adaptive method.   For  insufficiently  distinct particle population minima, there is first determined, on the basis of histograms  containing  corresponding  distinct  particle population minima and maxima, a characteristic difference quotient:       The separation threshold value associated with the insufficiently distinct particle population minimum is determined on the basis of the characteristic difference quotient according to:  Sx(j,k)unres= (Max.(k) - Min.(j))unres.Qx(j,k)res+ Min.

Granted: 1992-08-18
Abstract: Abstract of the Disclosure A method of operating a computer system is disclosed to effect user-custimization, primarily foreign language translation, of standard system-supplied screen displays without the need to modify underlying system source code.  A translation environment includes an autonomous processor (250) interposed between a host system (100) and access devices (201,202).  Information transmitted between the host and access device is diverted to the processor for intermediate processing.  One phase of this processing generates a translation file (500) which stores a mapping relationship between a first language screen and its second language counterpart.  This translation file is invoked during the second processing phase to effect a translation from the first-to-second language upon a host response and from the second-to-first language upon a host request.
