Abstract: A process for forming metal compositions containing cellular in situ composites. A metal composition containing at least 25 volume percent liquid is cooled to produce aligned columnar dendrite growth.

The metal compositions are particularly useful in rotating machinery.

Abstract: A way of automatically inspecting a machined part, for example, to a tolerance of 0.001 inches. A minicomputer monitors a change in phase, for example, of wave energy impinging upon a sample part and compares it with a change in phase of such energy for a standard or master part, any difference between the monitored changes being interpreted to determine if the sample is within acceptable tolerance limits. The inspection approach described uses no moving parts and can be used to inspect many dimensions of a part simultaneously in less than a second. Acoustic waves or microwave electromagnetic wave energy can be used to inspect parts of any shape. The inspection system disclosed can be used, as well, to monitor the geometry of an object over time to note any changes in said geometry. And the concepts of the inspection system can be employed in conjunction with robot-controlled devices to provide close-positioning data for such devices.

Abstract: A system operable to measure the time varying forces transmitted by a body and to combine the forces transmitted by different parts of the body. The system can be employed to measure physiological forces associated with motion of the body such as the gait of humans or animals. It can also be employed to measure forces internally generated by the body at rest such as ballistocardiographic and posture control forces. The posture control forces can be used as a measure of lameness. The Fourier transform of the force ballistocardiogram and posture control forces are found to contain information related to physiological condition. In some configurations the system employs ceramic capacitors as piezoelectric force transducers in a special circuit. The use of ceramic capacitors as pyroelectric bolometers is also discussed.

Abstract: Improved cell culture microcarriers, and methods for their production and use, are disclosed herein. These improved microcarriers have positive charge capacities adjusted and/or controlled within a range suitable for good cell growth. One method for producing such improved microcarriers is by treating beads formed from polymers containing pendant hydroxy groups, such as dextran beads, with an aqueous solution of an alkaline material and a chloro- or bromo-substituted tertiary amine under precisely controlled conditions to produce the desired exchange capacity. The resultant positively charged microcarriers have been used in microcarrier cultures to produce outstanding growth of anchorage-dependent cells. Such cells can be harvested, or used for the production of viruses, vaccines, hormones, interferon or other cellular growth by-products.

Abstract: A process and apparatus for treating materials, such as solid, particulate material, wherein the particulate material is introduced into a heat transfer medium, the density of such medium being different from that of the particulate material and the temperature of such medium being higher than that of the particulate material when so introduced. The particulate material, the individual particles of which are preferably introduced separately, travels through the medium and becomes heated thereby to a generally flowable state. The flowable particles of the particulate material thereupon leave the fluid and coalesce to form a flowable mass thereof external to the heat transfer medium.

Abstract: A racket having a primary frame and a secondary frame, the latter being disposed within and being secured to the primary frame. The secondary frame contains the string surface of the racket and is adapted to distribute forces in such a way that the "sweet spot" of the racket is much larger than in a conventional racket of the same size. Use of a secondary frame permits manufacturing economies not permitted by the more conventional design.

Abstract: A method of liquid phase epitaxial (LPE) growth of, for example, a semiconductor material or an oxide material whereby growth upon a seed in a seed-solution system is affected by passing electric current in an appropriate direction to effect migration of the materials to the growth interface or away from the interface and then cause deposition of desired materials upon said growth interface.

Abstract: A process is described which combines polycrystalline isolation of collectors and shallow oxide isolation of bases. This approach is capable of providing deep dielectric isolation, surface planarity and the high density of walled emitter geometries, a combination heretofore unobtainable by any other means.This isolation scheme has been used to fabricate ECL gate chains. The transistors were located in 2.5 micron thick n-epi islands surrounded by 5.times.10.sup.5 ohm-cm polysilicon selectively oxidized with silicon nitride masking to a thickness of one micron. The oxide "bump" at the nitride mask was typically 3000 A and the epi-poly step height was as small as 2600 A. The circuits have polysilicon resistors and were fabricated using both thermal diffusion and ion implantation. The power-delay product of these circuits was approximately one-half that of junction isolated circuits.
