Abstract: STORED CRYOGENIC REFRIGERATION                         ABSTRACT A holding chamber may be supplied from a storage vessel system with a cryogen, such as liquid CO2, or it may itself be large enough to take the place of a separate storage vessel.  The temperature within the holding chamber is reduced to the triple point or below to form a refrigeration reservoir of solid cryogen, as by removing vapor from the chamber to cause evaporation or by employ-ing mechanical refrigeration.  The stored cooling power of the reservoir is later employed to meet a large or a periodic refrigeration demand and is thereafter replenish-ed over a number of hours, preferably during a period of non-peak electric demand.  This storage principle can be incorporated into a variety of different refrigeration systems,  For example, a CO2 storage system may be used to produce and store solid CO2 during a period of low demand upon a coupled mechanical refrigeration system; thereafter, the solid CO2 is used to supplement the mechanical system during a high-demand period, thereby increasing the effective refrigeration capacity of the mechanical system.

Abstract: PRESERVATIVE APPLICATOR FOR A ROUND BALER        Abstract of the Disclosure A round baler has a conventional pickup and an approximately horizontal, wide, lower conveyor for removing hay from a field and delivering it rearwardly in a transversely extending mat to a transversely extending bale chamber where it is rolled into a cylindrical bale.  The upper run of the lower conveyor is approxi-mately tangential to the lower side of the forming bale so that there is a "pinch point" where the incoming mat of crop material converges on the periphery of the forming bale.  A series of fluid dispensing nozzles spaced across the machine connected to a source of preservative carried on the baler is disposed so that preservative may be applied to the hay close to the pinch point across the lateral extent of the bale chamber.  The incoming mat may vary in width and in lateral disposition relative to the baler conveyor system and sensors spaced across the machine and used to detect the presence or absence of hay and control fluid valves in the nozzle lines so that preservative is released only adjacent those portions of the bale where hay is being added.  In a preferred embodiment, the nozzles are carried above the incoming mat and direct preservative downwardly and rearwardly adjacent the pinch point and the hay sensors are associated with compressor rods associated with the pickup assembly.

Abstract: ABSTRACT OF THE DISCLOSURE           In the exemplary embodiments of the invention disclosed, thermal neutron decay characteristics of an earth formation, e.g. the thermal neutron decay time constant   and the macroscopic capture cross section  , are measured by detecting indications of the thermal neutron concentration in the formation during a selected set of two different measurement intervals between neutron bursts and forming a ratio of such measurements, as accumulated for an appropriate length of time, from which the measured value of the decay characteristic is derived.  The particular set of measurement intervals used is selected from among a number of possible sets as a function of a previously measured value of the decay characteristic.  Each measurement interval set is used over only a specific range of decay characteristic values for which it has been determined, in accordance with a previously established relationship between the decay characteristic value and the ratio of the thermal neutron concentration measurements for the set.  The measured value of the decay characteristic is then determined from the actual measured value of the ratio for the selected measurement interval set and the previously established relationship for that set. Each measurement interval perferably consists of a plurality of contiguous, discrete time gates whose durations and times of occurrence are adjustable in common by a finite number, e.g. four, of discrete scale factor values F, each corresponding to a specific range of decay characteristic values.

Abstract: Abstract of the Disclosure The optical beam scanner employs novel utilization of the well known Stark effect.  By means of an external applied voltage, a change in the index of refraction of an optical medium is produced.  This produces a bending effect on light transmitted through the medium.  Varying the applied voltage can be used to vary the refractive index, or a refractive index gradient may be produced by providing a gradient in the applied field, to produce no moving parts scanning of the optical beam.

Abstract: Abstract of the Disclosure A method for fabricating an integrated circuit semiconduct-or device comprised of an array of MOSFET elements having self-aligned or self-registered connections with conductive interconnect lines.  The method involves the formation on a substrate of a thick oxide insulation layer surrounding openings therein for the MOSFET elements.  A gate electrode within each opening is utilized to pro-vide self-registered source and drain regions and is covered on all sides and on its top surface with a dielectric layer.  After source-drain diffusions  a relatively thin dielectric protective layer is initially applied to the entire chip prior to the appli-cation of an upper insulative layer.  When oversized windows are etched in the upper insulative layer the protective layer prevents overetching of the gate dielectric layer  thus preventing shorts or leaks between conductive and active areas and providing self-aligned contacts with minimum spacing from adjacent conductive areas.  With the present method the additional internal protection is provided for in MOS devices with source-drain regions formed either by diffusion or ion implantation.
