Title: Circulating air refrigerator with removable divider shelf
Inventor: GIDSEG EDWARD
IPC: F25D23/06
Filed: 1979-04-03
Granted: 1981-06-09
Abstract: CIRCULATING AIR REFRIGERATOR WITH REMOVABLE DIVIDER SHELF ABSTRACT OF THE INVENTION An improved refrigerator of the forced refrigerated air type is disclosed in which a divider shelf is provided for the convenience of the user who wishes to convert a portion of the freezer section into a standard refrigeration section or a portion of the standard refrigerator section into a freezer section. The shelf is formed of an insulating material and is dimensioned and shaped to be positioned in a selected compart-ment in any of a plurality of selectable locations. The shelf has a resilient sealing member along peripheral portions which engage the corresponding walls of the compartment in which it is positioned so as to permit the shelf to selectively alter the flow of refrigerated air in such a manner as to permit the sep-arate thermostatic temperature control of the separate sections created by the shelf. Depending upon the desired application, the shelf may or may not include a thermostatically controlled aperture to further selectively control the flow of frigid air thereby also controlling the temperature of the section thus created. Various constructions of the shelf permit the consumer to conveniently and quickly convert the refrigerator from a standard arrangement to a plurality of selectable and temperature controllable arrangements including an energy saving arrangement in which a part of the standard refrigerator section or freezer section may be totally inactivated.

Abstract: 16                  48,005 ABSTRACT OF THE DISCLOSURE A support system for supporting the stationary ceramic vanes and ceramic outer shrouds which define the motive fluid gas path in a gas turbine engine is shown. Each individual segment of the ceramic component whether a vane or shroud segment has an integral radially outwardly projecting stem portion.  The stem is enclosed in a split collet member of a high-temperature alloy material having a cavity configured to interlock with the stem portion. The generally cylindrical external surface of the collet engages a mating internal cylindrical surface of an aper-ture through a supporting arcuate ring segment with mating camming surfaces on the two facing cylindrical surfaces such that radially outward movement of the collet relative to the ring causes the internal cavity of the collet to be reduced in diameter to tightly engage the ceramic  stem disposed therein.   A portion of the collet extends out-wardly through the ring segment opposite the ceramic piece and  is  threaded  for receiving a nut and a compression washer for retaining the collet in the ring segment under a  continuous  biasing  force  urging  the  collet  radially outwardly.

Abstract: Abstract:     The invention relates to the carbonylation of olefinic compounds in the presence of a cobalt carbonyl catalyst. The reaction is carried out in the presence of a secondary phosphine oxide represented by the general formula                          (I) wherein R1 and R2 may be the same or different and each represents a substituted or unsubstituted hydrocarbon residue having not more than about 20 carbon atoms, in an amount of 0.2 to 20 moles per gram atom of the cobalt.  This makes it possible to separate the reaction product from the reaction mixture by direct distillation without any such special operation for catalyst separation as required in conventional processes.  The distillation residue which con-tains the catalyst can be recycled for the reuse thereof in the carbonylation.

Abstract: CLOCK CHECK CIRCUITS USING DELAYED SIGNALS                 Abstract of the Disclosure In a data processing or transmission system which includes at least two synchronized clocks, for example - T-rings A and B which generate timing pulses Tai and Tbi for microinstruction execution, synchronism is checked by logic circuitry which receives pulses from the clocks.  At least one of the pulses is delayed by one or more pulse period durations ti.  The logic circuit output signal is used as an input to an indicator latch which is period-ically set by an independent check oscillator or clock. In a preferred embodiment, the delays are introduced by master-slave flip-flops, which receive predetermined combinations of the T-signals and set by the indepen-dent check clock.  Several delay latches and associated AND gates may be used for different logical combinations of delayed and undelayed T-signals.  This scheme can easily be expanded to accommodate more than two synchronously operating clocks.  These circuits check not only the instantaneous synchronism of the clocks, but also the correct sequencing of clock pulses.  The check is also feasible if the T-ring counters are operated with a variable number of clock pulses per microinstruction execution.

Abstract: ARTICULATED PLOW WITH HORIZONTAL ANGULARITY BETWEEN ITS FRAMES                ABSTRACT OF THE DISCLOSURE      The horizontal diagonal angle (z) of the rear frame (16) of an articulated plow (11) is greater than the horizontal diagonal angle (y) of the front frame (14), thus providing a lead angle (x) between the frames (14, 16).  This construction reduces the overcut by the plow bottoms (17) that would otherwise occur due to the lateral flexing of the rear frame (16).  The lead angle (x) can be adjusted between predetermined minimum and maximum values by moving an eccentric (51) between pre-determined positions of pivotal adjustment.  The eccentric (51) is part of a pivot joint (33) which together with a pivot joint (32) establishes the transverse pivot axis (31) between the articulated plow sections (12, 13).

The ice island is useful as a base for oil field operations, for oil and gas storage, for docking ships during thaw periods, and the like.  The structure comprises a plurality of elongated hollow wall elements adapted to be vertically oriented and assembled in open water to form a bounded area.  The elements become frozen in place during the winter and the bounded area is intermittently flooded at intervals to permit accumulation of ice sufficient to sink the ice island to the marine bottom,  Additional wall elements are added to the first wall elements to form upward continuations to contain the flooding water and accumulated ice.  Pumps are provided to convey water to the upper surface of the island for freezing, and to carry off brine during the freezing process.  Refrigeration equipment can be utilized to keep the ice island in a frozen condition during seasonal thaws.  The island can be adapted to be moved to other sites during thaw periods.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to an integrated, two stage coking and steam cracking process for the production of un-saturated light hydrocarbons.  A heavy hydrocarbonaceous oil is first coked in a fluid coking zone.  High temperature cracking in the presence of steam is carried out on the vaporous coker conversion product by injecting into the vapors a stream of hot coke particles at a sufficient temperature and in sufficient amount to raise the coker vapors to steam cracking temperature and supply the endo-thermic heat of reaction.  The solids are separated from the gas and sent to the fluid coking zone and the gas is quenched to stop olefin degradation reactions.
