Abstract: Abstract:    A modification to thermogravimetric analysers with data acquisition devised to allow concurrent TG (thermo-gravimetry) and DTA (differential thermal analysis) measurements employs three samples mounted close to each other in a TG furnace.  Two of the samples are active ones, i.e. of the material to be analysed, and the third is a reference sample of an inert material.  The first active sample is suspended from the beam of a thermo-balance.  The change in weight of this sample is recorded and plotted versus the temperature of the second active sample.  The sample thermocouple and another identical thermocouple are placed in contact with crucibles containing the second active sample and the reference material, respectively.  The differential temperature between the sample and the reference material is taken from the two identical thermocouples.  The differential signal is amplified and plotted against the temperature of the second active sample.  The two active samples are substantially identical to each other in geometry, i.e. amount and shape.

Abstract: 21                  49,750 ABSTRACT OF THE DISCLOSURE An elevator  system which generates  a  landing speed pattern having the advantages of both digital and analog based patterns, without the disadvantages of eith-er,  by generating  a  landing  speed pattern which is  a digital,  i.e.,  absolute position,  and analog composite. The absolute position of the elevator car in the landing zone of a target floor is detected at only a few points on each side of floor level, and an absolute pattern value is stored in memory for each such point.  The stored speed pattern values are retrieved as the car arrives at each absolute position point  and used for  establishing  the landing speed pattern,  with the  last  such value being modified to provide a continuous pattern which smoothly blends with the next stored speed pattern value as the elevator car reaches the next absolute position point.

Abstract: Abstract of the Invention In a method of recovering petroleum from underground formations penetrated by a production well, superheated steam and then hot hydrogen are injected by way of the well into a preheated formation zone next to the well.  The hydrogen is injected under sufficient pressure to cause hydrogenation of the petroleum in the heated zone.  The well is shut in and the hydrogen in the heated zone is allowed to "soak" for a period of time after which the pressure in the well is lowered and petroleum is recovered from the heated zone by way of the well.  The cycle can be repeated a number of times.    By way of another well spaced from the production well, fluid under pressure is injected into said formations to drive petroleum in said formations between the two wells to the production well for recovery.  hydrogenation of the petroleum occurs as it is driven through the heated zone in the presence of the hydrogen therein.

Abstract: ABSTRACT           Apparatus for heart rate fluctuation power spectrum analysis obtains an electrocardiogram signal from an electrocardiograph machine and a respiratory rate signal from an electroplethysmograph machine. These signals are processed by a data acquisition system to provide output suitable for heart rate fluctuation power spectrum analysis by a mini-micro computer.          Data manipulation includes correction of artifacts by substituting an appropriate heartbeat interval for detected heartbeat intervals for which the variance exceeds a preselected range of slewing rates. Trending of data and overlapping data analysis increase the analytical capabilities of the apparatus.          Methods of treatment for conditions manifested by abnormalities in a heart rate fluctuation power spectrum involve applying treatments when spectral abnormalities are observed.  Specific abnormalities indicating the need for treatment include:  a level belowabout 0.1 (beats/min.)2 in the power spectrum of heart rate fluctuations at a frequency between about 0.04 and about 0.10 Hz; a marked increase to above about 10 (beats/min.)2 in heart rate fluctuations at a frequency between 0.04 and about 0.10 Hz; and a ratio of the area under a heart rate fluctuation power spectrum of a peak at a frequency between about 0.04 and about 0.10 Hz to the area under a peak in the respiratory heart rate fluctuation power spectrum centered at the mean respiratory rate (as measured by the apparatus) at about 0.1 Hz as having a value less than 2.0 for longer than or equal to about one hour or as having an absolute value greater than about 50.
