Granted: 1994-07-26
Abstract: A combined refrigerator/freezer unit provides a step motor driven damper for adjusting the relationship between the  amount  of  chilled  air  delivered  to  the  freezer compartment and the amount of chilled air delivered to the refrigeration department.   The step motor, and in turn, the damper,  is  controlled  by  an  integrated  circuit  which receives  signals  from  temperature  sensors  in  each compartment.  The control produces pulses which cause the step motor to readjust the position of the damper to correct temperature imbalances which exist within the two compartments.  The step motor functions to move the damper to predetermined adjusted positions without requiring any feedback to establish the actual position of the damper before  and  after  each  adjustment.    The  control  also functions  during  defrost  to  cause  the  evaporator temperature to be raised prior to the operation of the defrost heaters.

IPC: C12R1/19
Filed: 1991-07-10
Granted: 2005-08-16
Abstract: A member of a specific binding pair (sbp) is identified by expressing DNA encoding a genetically diverse population of such sbp members in recombinant host cells in which the sbp members are displayed in functional form at the surface of a secreted recombinant genetic display package (rgdp) containing DNA encoding the sbp member or a polypeptide component thereof, by virtue of the sbp member or a polypeptide component thereof being expressed as a fusion with a capsid component of the rgdp. The displayed sbps may be selected by affinity with a complementary sbp member, and the DNA recovered from selected rgdps for expression of the selected sbp members. Antibody sbp members may be thus obtained, with the different chains thereof expressed, one fused to the capsid component and the other in free form for association with the fusion partner polypeptide. A phagemid may be used as an expression vector, with said capsid fusion helping to package the phagemid DNA. Using this method libraries of DNA encoding respective chains of such multimeric sbp members may be combined, thereby obtaining a much greater generic diversity in the sbp members than could easily be obtained by conventional methods.

Granted: 1996-07-30
Abstract: A sensor grid system  (10),  and a method of operating a sensor grid system, having a first array of inductors (14a) and a second array of inductors (14b). The first and the second arrays are each responsive to a moveable coil (18) that  transmits  an  electromagnetic  signal  for  having  a detectable signal  induced therein.  The method includes a first step of determining an expected position of the coil relative to an array of inductors. A next step selects a pair of inductors that are located near to the expected position. A third step measures the signals induced into the pair  of  inductors,  and  a  fourth  step,  based  on  the measurement step, determines any additional inductors from which measurements are required to interpolate the actual position of the coil.  A fifth step measures the signals induced  into  the  determined  ones  of  the  additional inductors, and a sixth step computes and reports the actual position of the coil based on the results of the first and the second steps of measuring.  Significantly,  the pair of inductors and the additional inductors include all inductors that are required to compute the  actual position of the coil,  and includes no inductors that are not required to compute the actual position of the coil.

Abstract: Disclosed is a process for preparing a solid, light weight mineral foam which is stable during its preparation and during its subsequent curing and drying and which, thanks to its composition and the way it is prepared, can be injected in situ, substantially like a urethane foam. This foam has a density ranging from 10 to 65 lb/pi 3 and is made of 1 part by weight of a solution of phosphoric acid of given concentration in which is dissolved polyvinyl alcohol in such an amount as to make the solution viscous; from 0.03 to 6 parts by weight of wollastonite containing from 0.5 to 4% by weight of a carbonate salt; and from 0.2 to 10 parts by weight of water. The amount of water depends on the concentration of the solution of phosphoric acid and of the required density of the foam, it being understood that the more concentrated is the solution of phosphoric acid and/or the lower is the required density, the higher is the amount of water. The products made of such a foam are rigid and can be used for thermal and acoustic insulation.

Abstract: A method and apparatus for transmitting and receiving acquired digital data over bandpass channels (i.e. channels having a limited range of frequencies) at high data transmission rates. Combined amplitude and phase modulation (quadrature ampli-tude modulation) is applied to the digital data and the sampled digital waveform converted to an analog waveform for passage over the bandpass channel. The sample rate is chosen as an integer multiple of the symbol rate and carrier frequency to signifi-cantly reduce processing overhead. Reception of the acquired data is similar to transmission and involves an analogous ampli-tude and phase demodulation. The quadrature amplitude modulation technique of the present invention is applied to an oil well-logging application to transmit the data acquired from the downhole logging instruments over the logging cable (bandpass channel) at high transmission rates.
