Title: Coil winding method for maximum utilization of winding envelope
Inventor: YOUNG CARL E
IPC: H02K3/18
Filed: 1988-12-01
Granted: 1992-03-31
Abstract: COIL WINDING METHOD FOR MAXIMUM UTILIZATION OF WINDING ENVELOPE            Abstract of the Disclosure A coil winding method wherein only one-half turn is wound in the bottom slot of the first layer of the coil.  This results in the loss of one-half turn, but causes the normal crossover from the first layer to the second layer to occur on the side of the coil opposite the lead-end.  The last one-half turn of the second layer wound in the bottom slot of the first layer, thereby recovering the lost one-half turn. Additional turns are added in this manner until approximately one-half of the layers have been wound. Thereafter, the usual progressive winding method is employed.  As a result, crossover related build-up in the completed coil is distributed between opposite sides of the coil and the number of turns within the allowable profile is substantially maximized.

Title: Process for rapidly determining the swelling-clay content of earth formations
Inventor: KROEGER MICHAEL K
IPC: G01N27/22
Filed: 1989-02-09
Granted: 1991-09-10
Abstract: ABSTRACT OF THE DISCLOSURE     A method for determining at wellsites the swelling-clay content of shales and shaly sandstones by high-frequency dielectric measurements including:  grinding a rock sample to a size suitable for testing; washing the rock sample with a fluid having a water activity substantially less than water, which may contain a soluble cation; packing the washed rock sample into a sample cell suitable for dielectric measurement; measuring the dielectric constant at a preselected frequency; and comparing the measured dielectric constant of the rock sample to calibration curves.  A determination of the swelling-clay content may be performed at different levels depending on the nature of the samples to be compared. In the preferred embodiment, four levels of swelling-clay determination are possible.  The first, or narrowest, level of determination may be used when the swelling-clay content of samples from a single site is to be determined.  The second level of determination may be used when the swelling-clay content of samples from different sites which contain similar rock matrices is to be determined.          The third level of determination may be used when the swelling-clay content of samples from different sites which contain varying rock matrices is to be determined.  The fourth, or broadest, level of determination may be used when the swelling-clay content of samples of varying rock matrices is to be determined and the swelling clay  are known to be interstratified with illite clays.

Abstract: Abstract of the Disclosure The specification describes and claims a tissue expander capable of insertion in a human body to induce formation of a pocket  into  which  a  mammary  prosthesis  may  be  inserted comprising (a) an expander portion (12,102) which is flaccid and is adapted to be inflated progressively in the body to induce formation of said pocket, (b) a support plate portion (14,114) which is sufficiently flexible that it may be bent or folded upon itself for insertion into or removal from the body through an incision in the body and to recover to a plate-like condition within the body,  (c) feed tube means (20,120) attached to the expander  portion and having  a valve  (24,124)  through which inflating medium may be supplied into the expander portion, and (d) releasable securing means (18,30,118,130) whereby the support portion and the expander portion are connected together until it is desired to release the expander portion from the support portion.   Preferably  the  releasable  securing means  comprises snap fastener means, a male portion of the snap fastener means being secured to the expander portion (a) and a female portion of said snap fastener means being secured to the support portion (b).  The releasable securing means facilitates location of the expander portion and the valve, and permits detachment of the expander  portion  from  the  support  portion  as  desired.  The support portion supports the expander portion in the body and resists  contraction of the  fibrous  capsule produced as  scar tissue forms.  It also forms a substantially flat wall for the developing pocket and provides a pressure plate which serves to ensure that expansion of tissue,  induced by inflation of the expander portion, takes place in a direction outwardly of the body.

Abstract: ABSTRACT OF THE DISCLOSURE         A continuously variable transmission includes a power input driving a sun gear which in turn drives a plurality of planetary gears.  Within each planetary gear is mounted an over-rolling clutch.  The planet gear is free to rotate about its raceway in one direction and is locked from rotation in the opposite direction.  The shaft mountings for each planetary gear are suitably journalled in a carrier ring rotatably mounted within the housing.  An internal gear, integrally mounted within the output housing, meshes with the planetary gears and is driven by them.  An eccentric system, comprised of two nested eccentrics within the housing and anchored to an axle, controls the degree of oscillation imparted to the planetary gear raceway shafts.  The eccentric system is continuously positionable so as to increase the rotation of the input sun gear from a one-to-one ratio up to the maximum designed output.  As the eccentricity is increased, the planetary gear system superimposes a pulse drive on the sun gear that exponentially multiplies the drive rotation rate.  Thus, the output housing is driven at a greater rate of rotation than the planetary carrier.  When the eccentrics are at the zero eccentricity position, the transmission operates as a direct drive with no internal gear motion.

Title: Arrangement for dpcm-coding of video signals
Inventor: MATTAUSCH HANS-JUERGEN
IPC: H04N19/50

Granted: 1992-10-06
Abstract: ABSTRACT OF THE DISCLOSURE     An arrangement for DPCM-coding of video signals.          A  DPCM  coder  wherein  estimated  values  (s) are respectively subtracted from digitized picture element signals (s) and the estimated errors are used for signal transmission  after  quantization  and  coding.    Every estimated value  (s)  is derived from a reconstructed picture element signal formed in an adder.   A limiter between the first adder and the subtractor that reduces the calculating speed can be removed from the time-critical path in that the limiter function is distributed onto  two  paths  that  calculate  in  parallel.      A subtraction of the signal taken at the adder output occurs in the one path; the subtraction of an upper or lower limit value (.alpha. ? G-, .alpha. ? G+) weighed with .alpha.  and through-connected  via  a  switch  from  the  respective picture element signal (s) of the input side is carried out on the other path.  An overflow recognition element and a multiplexer provide that only a difference of the two differences formed up to this point, that relate to the  actual  addition  result  (no  overflow,  positive overflow, negative overflow), is through-connected to a quantizer.
