Inventor: SCHOLZ MATTHEW T
IPC: B32B5/02
Filed: 1990-06-06
Abstract: Abstract of the Disclosure The   present   invention   relates   to   novel orthopedic  casting  materials  having  superior  layer  to layer lamination, and methods for preparing the same.  The orthopedic casting materials comprise a resin-coated scrim having  a  plurality  of  projections  along  at  least  one surface thereof.  Preferably, each projection comprises a bundle of at least about 8 filaments, and the scrim has from about 75 to about 1500 projections per gram of scrim. the  projections  serve  to  mechanically  interact  with adjacent layers  of  the material,  thereby  significantly enhancing  the  lamination  properties  of  the  resultant material and resisting delamination once She material has cured.

Abstract: La présente invention concerne des halogénures de terres rares déshydratés et un procédé de production de ceux-ci. Elle concerne plus particulièrement un halogénure de terre rare de type chlorure, bromure, iodure contenant moins de 1,5% en poids d'eau et moins de 3% en poids d'oxyhalogénure. Cet halogénure est obtenu par déshydratation d'un halogénure hydraté par passage d'un courant d'un agent déshydratant halogéné (hydrure d'halogène) à travers la masse à déshydrater. Ce procédé permet de deshydrater ces halogénures. Commercialement, les procédés connues ne permettent pas d'abaisser l'eau à des valeurs faibles.

Abstract: DOUBLE CONTAINMENT TANK LINE SYSTEM                      Alan R. Lasson ABSTRACT OF THE DISCLOSURE    A plastic liner sheet is positioned between an outer bottom wall and an inner bottom wall of a dual wall tank providing uniform spacing and a degree of support.  The liner sheet is molded with integral spacer elements in the form of semi-spherical bosses extending from the top and bottom surfaces of the liner sheet.  Equilaterally positioned depressions surround each boss so that a boss on one side forms a depression on the opposite side and vice versa.  The support function is augmented by providing a series of steel balls which are placed in selected depressions dependent on the expected loading on the tank bottom from the weight of the tank and its contents.  The inner tank bottom may be constructed by butt welding a series of steel plates of desired shape to form the tank floor with weld backing plates resting on the liner top and supported by a linear line of the spaced steel balls in a spaced number of linearly aligned depressions.

Title: Propellable articulating animal toy
Inventor: FOGARTY A EDWARD
IPC: A63H7/02
Filed: 1991-05-23
Abstract: ABSTRACT OF THE DISCLOSURE    A propellable articulating animal toy  (10) having a flexible,  pliable  stuffed  body  (12)  which  simulates  an animal,  preferably a puppy,  having  freely moveable body components.  The body (12) fits over a housing (14)  which includes at least one ground-engaging support wheel  (32) connected within the housing (14).  The housing (14) also includes a forwardly extending lever (34) pivotally mounted in the housing (14) and structured to be pivotally articula-ted up and down through an acute angle  (A) by eccentric driving engagement with the wheel (32) as the toy (10) is manually propelled over a flat surface.   The animal body (12) also covering the lever (34) is thus made to bob up and down appearing to be running or jumping as the toy (10) is propelled over the flat surface.  Although only the forward-ly portion of the animal body (12) is articulated by the pivoting movement of the lever (34), the entire body (12) and all body components take on a realistic running motion due to the pliable nature of the animal body (12) and its plush covering, which may also be made removable for holding and cuddling.   A bellows  (78) may also be included which produces a sound similar to that of the particular animal such as the bark of a dog.  The bellows (78)  is operably moved by the interior portion (82) of the lever (34) so as to produce a sound coincident with the running motion.  The preferred embodiment  includes  a rearwardly  and  upwardly extending push handle  (16)  for propelling  the  toy  (10) across the ground and a detachable leash (18/20) to add to the realism of the toy (10).

Patent CA-2051212-A1 (CA)
Title: Packet data communication system
Inventor: TYMES LAROY
IPC: G06K7/00
Filed: 1991-09-12
Abstract: A packet data transmission system is used to link a number of remote hand-held data-gathering units such as bar code readers to a central computer which maintains a database management system. Data packets are sent from the remote units by an RF link to intermediate base stations, then sent by the base stations to the central computer by a serial link. Direct sequence spread spectrum modulation is used for the RF link. The remote hand-held units initiate an exchange using RF transmission to and from the base stations, receiving only during a rigid time window following a transmission from the remote unit. The base stations cannot initiate communication to the remote units, but instead send data to the remote units only as part of the exchange.

Title: Alumina coating for the protection of stainless steel
Inventor: CAPUANO GUIDO A
IPC: C25D9/10
Filed: 1991-09-23
Abstract: An alumina coating, produced by aluminium electroplating of a stainless steel containing from about 0.02 to about 0.2% of misch metal or 0.2 to 0.8% of titanium, improved the oxidation resistance in air of these stainless steels at least up to 1100°C. In thermal cycling tests carried out between 1000°C and room temperature, these steels maintained an excellent adhesion matrix-coating, for at least up to 500 cycles. In fact, the addition of misch metal or titanium in stainless steel provided good bonding between coating and matrix. The porous nature of thealumina coating was found very beneficial because it favors the absorption of the thermal and growth stresses.

Title: Method and arrangement for dividing the frequency of an alternating voltage with a non-whole-numbered division factor
Inventor: FOERG PIRMIN-NIKOLAUS
IPC: H03K23/64
Filed: 1991-12-13
Abstract: ABSTRACT OF THE DISCLOSURE         In a synchronous data network such as a synchronous digital hierarchy,  frequency generators in every network node must be followed up by synchronous signals having, for example, a frequency of  2.048  or  1.544 MHz,  and which are derived from a common frequency normal.  A divider having a non-whole-numbered division factor that can also be utilized elsewhere is lacking for this.          Over and above this, the possibility of correcting conditioned frequency errors by positive/zero/negative pulse stuffing is also lacking.   The former is enabled by an arrangement comprising a divider 23 that is periodically switched between two auxiliary division factors (m, n).  The latter is allowed by an arrangement wherein the positive  (PST) and negative  (NST)  pulse stuffing signals proceed partly directly and partly delayed to a decoder and, via this decoder, to an accumulator.  Addresses generated by the latter cause a memory pair for forward x-values and y-values defined dependent on the pulse stuffing signals via a multiplexer to a further accumulator whose carry signal drives the divider for the purpose of frequency correction.

Title: Method and apparatus for producing a porosity log of a subsurface formation corrected for detector standoff
Inventor: ALLEN LINUS S
IPC: G01V5/10
Filed: 1992-03-19
Abstract: A borehole logging tool is lowered into a borehole traversing a subsurface formation and a neutron detector measures the die-away of nuclear radiation in the formation. A model of the die-away of nuclear radiation is produced using exponential terms varying as the sum of borehole, formation and thermal neutron background components. Exponentially weighted moments of both the die-away measurements and die-away model are determined and equated. The equated moments are solved for the ratio of the borehole to formation amplitude components of the measurements.      The formation decay constant is determined from at least the formation and thermal neutron background terms of the weighted measurement and model moments. The determined borehole to formation amplitude ratio is used to correct the determined formation decay constant for the effects of detector standoff from the borehole wall. A porosity log of the formation is produced which is corrected for detector standoff from the borehole wall as a function of the standoff corrected formation decay constant calibrated in borehole models of known porosities.
