Title: Streamlined production of electric motor armatures and stators
Inventor: WHEELER DALE K
IPC: H02K15/09
Filed: 1987-05-21
Granted: 1991-10-08
Abstract: ABSTRACT OF THE DISCLOSURE            Two production lines for the manufacture of armatures or stators for electric motors are separated over at least part of their length by a common partition.  The juxta-posed  proximity  of  the  two  production  lines  allows operations on articles on both lines to be carried out simultaneously by equipment mounted on a common operating head.   Shuttles are provided upstream and downstream of coil winding areas so that armature or stator bodies from one production line can be automatically diverted to  a winder on the other  production line and returned when wound.   The height of the laminations  is determined by picking a stack close to the maximum height permissible, measuring  this  height  and,  if  necessary,  removing  a lamination via a vacuum line mounted on a measuring head.          After winding,  the ends of the magnetic wires  on the armature are stripped using a laser.  The dual highway style production  lines provide economy in  floor space  and operators,  and by use of the transfer  shuttles  enable bottlenecks of one line to be handled by the other line.                  .

Abstract: Abstract of the Disclosure In a differential planetary gear apparatus ac-cording to the present invention, a first shaft and a second shaft are rotatably supported in a casing.  A sun gear is fixed to the first shaft.  A fixed internal gear located in the casing is arranged concentric with the sun gear.  A rotary internal gear connected to the second shaft is arranged coaxially with the fixed inter-nal gear, and has the difference M in the number of teeth with respect to the number of the teeth of the fixed internal gear.  N (M ? N, N ? 1) planet gears, which revolve around the sun gear, are disposed at equal intervals circumferentially.  Each planet gear has a first portion, engaged with the fixed internal gear, and a second portion, engaged with the rotary internal gear.  Either one of the first and second portions of the planet gear is engaged with the sun gear.  When the number of planet gears is designated circumferentially by i = 1, 2, ..., N, the phase of the teeth of the first portion of the i-th planet gear is shifted in the period of {(i-1)M}/N with respect to that of the teeth of the second portion.  Thus, the phase of the teeth of the first portion can be shifted in response to the phase of the spaces of the fixed internal gear.  Therefore, if at least one of the internal gears satisfies the assembling condition, the number of teeth of the other internal gear can be freely selected, irrespective of the number of the planet gears.  In other words, the number of teeth of the internal gears and the speed ratio can be freely selected, irrespective of the number of planet gears.

Granted: 1992-05-12
Abstract: A probe unit for automatic determination of quality properties in meat ABSTRACT            A probe unit for automatic determination of quality pro-perties in meat has an oblong, tubular housing (5, 16) whose front part (5) mounts a double-acting drive cylin-der (4), the piston rod (10) of which is tubular and extends through both ends of the cylinder. The front end of the piston rod mounts a light reflection measur-ing means (12), and the rear end of the piston rod carries a pulse generator which cooperates with a rod-shaped reference means (17), firmly mounted in parallel with the piston rod, to produce electric pulses upon movement of the said rod, said pulses being applied to a counter whose display represents the position of the measuring means with respect to the cylinder. The signals from the measuring means represent the type and/or quality of the material in which the measuring means is present at any time. The probe unit is sturdy and reliable in operation and requires little space, in particular in transverse direction, and therefore lends itself parti-cularly well for incorporation in automatic systems with many probe units.

Abstract: ABSTRACT OF THE DISCLOSURE   A mechanism and method for operating a device for crimping a metal outer sleeve of a hose connector around the end of a flexible hose.  The device has a constrictor collet assembly for radially inwardly deforming the sleeve in response to axial movement of the collet assembly in a frusto conical die ring. Axial movement is imparted by a ram and a pair of pusher members mounted between the ram face and the collet assembly.  The pusher members are swung between open and closed positions by the operating mechanism which has a pair of lever arms connected to the pusher members at one end and to a pintle at the other end. The pintle is slidably mounted for lateral movement in a slot.  It is resiliently biased towards a forward end of the slot such that one element of the operating mechanism can be advanced to a first position whereat the pusher halves are closed and then further advanced to a second position into contact with a switch that activates the ram and causes the pusher members to shove the constrictor collet assembly axially deeper into the frusto conical die ring.

Title: Radon detection system
Inventor: FIMIAN KEITH S
IPC: G01T1/178

Granted: 1993-09-28
Abstract: TITLE OF THE INVENTION            Radon Detection System ABSTRACT      A radon detection system is provided with the capability   of   monitoring   certain   environmental parameters  together  with  certain  other  conditions indicative of possible tampering.  The environmental data allows the calculation of an accurate projection of average  long-term radon levels  in the  structure under  test  on  the  basis  of  a  relatively  short measurement period,  while the tamper data indicates whether an attempt has been made to tamper with the detection unit or the measurement conditions during the  test  period.   When  an  indication  of  possible tampering occurs,  the  system enters  an  accelerated data collection mode during which data  is  gathered that can later be used to determine whether tampering has actually occurred.  The detection system may be provided  with   first   and   second   detectors   for separately monitoring airborne levels of radon gas and radon decay products.   The  radon  gas  detector may include  a  scintillation  cell,  and  means  may  be provided to purge and then bypass the scintillation cell when high radon gas concentrations are detected. Methods  for measuring  and  reporting  radon  gas  and decay product concentrations are also disclosed.

Title: Method and system for geophysical exploration
Inventor: SONDERGELD CARL H
IPC: G01V11/00
Filed: 1989-07-19
Granted: 1993-03-30
Abstract: ABSTRACT         The present invention relates generally to a method and system for geophysical exploration and more particularly to a method and system for obtaining selected physical properties of the subterranean formations sur-rounding a wellbore and for obtaining inverse logs of the selected physical properties so as to aid the geophysicist in evaluating the oil and gas bearing potential of such formations.  In one embodiment of the invention, contin-uous core samples are obtained from along the length of a wellbore. Discrete samples are obtained from the contin-uous core samples at selected intervals so as to be repre-sentative of the formation lithologies traversed by the wellbore along its length.  The samples can then be proc-essed at the wellsite with a transportable laboratory so as to obtain measures of a plurality of selected physical properties of the subterranean formations representative of their in-situ condition.  An inverse log of each phys-ical property as a function of depth can be prepared with which explorationists can evaluate geophysical survey data for oil and gas potential.  In more detail, measures of the subterranean formation's compressional wave velocity, shear wave velocity, bulk density, saturated density, dry density, magnetic susceptibility and compressive strength can be determined from which one can also calculate the formation's acoustic impedance and porosity.  Addi-tionally, inverse logs of one or more of the physical pro-perties can be used to perform basin analyses.  When used for basin analysis, the physical properties of each inverse log can be used to calibrate geophysical survey data of the basin at one or more wellbore sites within the basin from which the inverse logs were obtained.  Having thus calibrated the geophysical survey data, exploration-ists can then extrapolate the physical properties to other locations in the basin remote to the wellbore site with the geophysical survey data to evaluate the oil and gas potential of the earth's formations at such remote locations.
