Abstract: ABSTRACT OF THE DISCLOSURE           Method and compositions are provided for deter-mining the thyroxine binding capacity of serum the value finding u e in determinations of free thyroxine index. A competitive assay is perfomed where antibody for T-3 (anti-triiodothyronine) and serum thyroxine binding sites compete for T-3 (triiodothyronine) in the assay mediums  the T-3 is present as free T-3 added in a predetermined amount and T-3 conjugated to an enzyme.  By combining the materials in a buffered aqueous medium with enzyme substrates, and de-termining the rate of reaction by the changing concentration of a light absorptive substance over a predetermined period, the thyroxine binding capacity of the serum can be deter-mined.

Abstract: ABSTRACT OF THE DISCLOSURE      Cryopumping speed of nitrogen, helium, hydrogen and neon can be increased by omitting the chevron baffle in a conven-tional cryopump and preventing incident radiation of about 300°K from striking surfaces used to cryosorb helium, hydrogen and neon.  An apparatus is disclosed utilizing three pumping surfaces created from open ended opposed nested cylinders.  A radiation absorbent coating is placed on one of the surfaces to shield the helium, hydrogen and neon pumping surface.  Refrigeration can be provided by a two-stage closed cycle cryogenic refrigerator.

Abstract: Abstract of the Disclosure An improved electrical resistor device is made by molding a body of ceramic material of positive temperature coefficient of resistivity so that a plurality of passages extend in a pattern in spaced side-by-side relation to each other between opposite ends of the body.  In molding the body, lands or abutments of resistor material are formed around the ends of alternate body passages at one end of the body and similar lands or abutments are formed around the ends of the other passages at the opposite end of the body.          A band of masking material is applied to the sides of the body extending around the body leaving the ends of the body, and bands of the body side surface adjacent each end of the body, free of masking material.  The masked body is then immersed in a coating bath for simultaneously coating the inner walls of the body passages, the ends of the body, and the unmasked bands of the body side surface with an electri-cally conductive ohmic contact material.  Preferably, the ohmic contact and masking materials are selected to be impervious to reducing atmospheres and the like for protecting masked and coated portions of the ceramic resistor material against degradation in such atmospheres.  Preferably, the ends of the body are immersed in an additional coating bath or are other-wise treated for coating at least the unmasked bands of the body side surfaces with a material characterized by low elec-trical contact resistance.  Thereafter, the outer ends of the abutments are abraded for removing coating materials from the ends of the abutments. In this way, ohmic contacts in alter-nate body passages are connected together at one end of the body to form a first device terminal having low contact re-sistence while ohmic contacts in the other body passages are connected together at the opposite end of the body to form a second device terminal.  Alternately, the ends of the body abutments are masked prior to immersion of the body in the contact coating baths for permitting omission of the noted abrading step.

Abstract: ABSTRACT Apparatus and method for providing a buffer stage, or cache memory command circuit, between a cache memory unit and a main memory unit.  The transfer of data between a main memory unit and a cache memory unit can be complicated because the circuits utilized in the cache memory unit and/or the main memory unit in effectuating the data transfer can be pre-empted. In addition, the data transfers must be executed in sequential order.     According to the present invention, the transfer of data is divided into two portions, a portion involving cache memory unit and a portion involving the main memory unit along with associated interface units.  The cache memory unit stores the data transfer commands and the associated data in sequential order.  The cache memory unit and the main memory and interface units can execute their respective portions of the data transfer independently permitting overlapped instruction execution.  The cache command buffer insures that the operations involving the two units of the data processing unit are executed in sequence.  When data transfer has been completed, the cache command circuit continues to the execution of the next data transfer in sequence.

Abstract: METHOD AND APPARATUS FOR INCREASING THE VERTICAL LOAD BEARING CAPACITY OF ICE            ABSTRACT OF THE DISCLOSURE         In order to increase the vertical load bearing capacity of an ice field such as may be found in the Arctic, whereby buildings, drilling rigs, or the like may be supported, an inflatable hull is positioned beneath the ice, initially in deflated form.  Inflation of the hull is carried out in conjunction with application of the load under control of level sensor means which govern the rate of inflation according to the deflection of the ice as the load is applied. Very high load bearing capacity may be obtained and maintained even for relatively thin ice, within a short period.  Degree of inflation control apparatus may be employed to accomodate varying loads, and a multiple-hull system is contemplated for practicing the invention over relatively large areas.

Abstract: PROCESS FOR PROVIDING SELF-ALIGNED DOPING REGIONS     Abstract of the Disclosure A process for providing ion-implanted regions in a substrate such as silicon beneath an existing layer such as silicon dioxide and being self-aligned to subsequently fabricated regions of said layer which includes providing a resist masking pattern above the existing layer wherein the resist masking pattern has vertical sidewalls (i.e., perpendicular to the upper surface of the substrate) or is undercut; ion-implanting impurities such as boron ions through the layer but not through the resist and portions of the layer beneath the resist, and depositing a layer of lift-off material such as aluminum on the existing layer and on the resist.  The implantation step must be performed after providing the undercut resist masking pattern, but before depositing the layer of lift-off material in order to achieve the desired self-alignment feature.  Because of the resist profile (i.e., vertical walls or being undercut) no lift-off material is deposited on the sidewalls of the resist and a gap is formed between the resist and that por-tion of the lift-off material which is above the existing layer.  The resist pattern is removed along with the portion of the lift-off material layer deposited thereon.  The now-exposed portion of the existing layer located beneath the previous resist pattern is then removed.  Finally, the re-maining regions of lift-off material are removed from above the regions of the existing layer.         The ion-implanted regions occur in the substrate beneath the remaining portions of the existing layer, are self-aligned to the boundaries of said portions, and corres-pond to a negative image of the original undercut resist masking pattern.

Abstract: ABSTRACT        Echo cancellation in signal transmission on four-wire telephone lines is effected digitally using an echo estimate and compensating for phase-roll between the echo and the signal originally transmitted.  Digitized samples of sine and cosine functions of a pulsation corresponding to the phase-roll are generated.  Digitized samples of a signal phase-shifted by 90° are obtained from the echo.  The same echo is delayed by a time equal to the time necessary for the phase-shifting operations. The samples of the phase-shifted and delayed signals are multiplied respectively by the samples of the sine and cosine functions, the resulting signals being added.  The multiplication and addition operations give rise in the echo to a frequency-offset equal and opposite to the offset introduced by the line.
