Title: Single evaporator, single fan combination refrigerator with independent temperature controls and method of adjustment
Inventor: WEBB WILLIAM M
IPC: F25D17/08
Filed: 1976-12-14
Granted: 1979-01-02
Abstract: ABSTRACT OF THE DISCLOSURE      A single evaporator, single fan combination refrigerator includes a temperature control system which thermostatically maintains the fresh food compartment at a desired temperature by cycling the refrigerator system on and off as required, and which controls freezer compartment temperature by varying airflow thorough a pair of ducts conducting refrigerated air from the evaporator chamber to the fresh food compartment. The freezer control operates a pair of main dampers disposed in the ducts. In order to compensate for variations in freezer compartment temper-ature which would otherwise result when the setting of the thermostatic fresh food control is changed, a pair of compensating dampers are also disposed in the ducts and operatively connected to the fresh food control for ganged operation with the thermostatic control. The dampers are constructed to only partially block airflow when in the fully-closed position. In certain embodiments, selection of damper characteristics is easier than in other embodi-ments, and a method of selection is described.

Abstract: Title:          Infinitely variable drive method and apparatus Abstract of the disclosure:          Method and apparatus for driving an apparatus by means of a drive motor and an infinitely variable transmission comprising an endless transmission member running on at least two V-shaped pulleys having conical sheaves spaced apart a distance controlled hydraulically by means of a pump, which provides the necessary fluid pressure for control of the transmission ratio. According to the invention means are provided for ensuring that the transmission member is tensioned before, and so long as, the transmission is mechanically loaded, using one and the same drive motor. This is achieved by driving the pump by the drive motor and providing a clutch between the drive motor and the transmission, which is hydraulically operated by means of fluid provided by the pump, so that the clutch does not connect the drive and the transmission unless there is sufficient fluid pressure for the transmission to function.

Abstract: ROLLER DROP DOOR              Abstract of the Disclosure Disclosed  is a rail house car door having a supporting track on a car side beneath a door opening.  The door is formed with a lower edge surface for support of the door on the top of the track in engagement with the track when the door is in a position to close the opening.  The lower edge surface ex-tends substantially through the width of the door and has a plurality of at least three intermediate openings with portions of a plurality of at least three longitudinally or spaced rollers extending therefrom.  The track can be sealed in contact with the door side beneath the door opening substantially throughout the length of the track and has a plurality of at least three corresponding intermediate copes of enlarged longitudinal dimension in the top of the track located to receive the rollers when the door is supported on the lower edge surface in a posi-tion to sealingly engage the track to close and seal the open-ing.  The copes' enlarged dimensions, during closing and just prior to final movement of the door into position to close and seal the opening, permit a final longitudinal sliding movement of the lower door edge surface on the top of the track to close and seal the opening, and during opening, permit an initial relatively short longitudinal sliding movement of the door edge surface on the track to initially open the opening.  This also permits at least two of the rollers to engage the top of the track and support the door with the lower edge surface removed from the track for longitudinal movement when the door is in other positions on the track.  The lower edge surface being located so as to define the inwardmost portion of the door adjacent the track such that in the closed position of the door, a seal is provided with the track and the potential damage to the track tending to move it closer to the car side can not clamp any portion of the door between the track and the car side, thereby hindering selective door movement.

Abstract: VISCOUS OIL RECOVERY METHOD      (D#73,500-RCA-19-F) ABSTRACT OF THE DISCLOSURE         Viscous petroleum may be recovered from viscous petroleum-containing formations such as tar sand deposits in a process employing steam and a light hydrocarbon in the C3 to C12 range, including naphtha and natural gasoline, and a cyclical injection-production program comprising repetitive cycles, each cycle comprising three steps or parts.  First steam or steam and hydrocarbons are injected and liquids are recovered from the formation without restriction so long as no vapor phase or live steam production occurs.  Next, steam and hydrocarbons are injected and production throttled until the formation pressure at the production well rises to a value  between  about 60%  to  95%  of the  steam injection pressure, after which fluid production is permitted without restriction  and  steam and hydrocarbon injection rate is reduced to 50% or less of the original injection rate.  The process should be applied to a formation in which adequate communication exist or in which a communication path is first established.   Suitable  hydrocarbons  include  C3  through C12 paraffinic or olefinic hydrocarbons including natural mixture  such as naphtha,  natural gasoline,  etc.  Optimum results  are  obtained if the pressurization and drawdown cycles  are initiated shortly after the beginning of the steam-hydrocarbon injection program, and the benefits include substantially increased oil recovery efficiency at all values of   steam   pore   volumes   injected,   reduced   pressure differential, reduced plugging of the communication channel, and production of a preponderance of the viscous petroleum in -I-the  form of an oil-in-water emulsion which is easier to handle and to resolve into relatively water-free oil than a water-in-oil emulsion.                             -I-
