Abstract: In use of laser radiation to ablate corneal tissue, to achieve a sculptured change in curvature of the optically used region of the cornea, a variable magnification (zoom) lens is combined with different sized apertures of an indexible mask to develop a relatively smooth profile for the changed curvature. The zoom-lens settings are varied in the course of cornea exposure through each of the succession of mask apertures. To do this, the range of zoom-lens magnification can always be less than 2:1, yet the zoom-lens system can effectively reduce to insigni­ficance the stepped profiling that is inherent in reliance only upon the indexed aperture technique. Also described are techniques to achieve compensation for delivered flux-density variation as a function of instantaneous zoom-lens setting, and programmable control of the area of delivered flux density in a manner to correct for parabolic or other fall-off in delivered beam intensity as a function of radius outward of the axis of beam delivery.

Abstract: A method for detecting and tracking moving objects in a digital image sequence having a stationary background by comparing the image sequence to a calculated background image sequence, whereby a sequence of binary object masks is calculated whose segments reproduce the shapes and positions of the moving subjects, and whereby the motion vectors of the moving objects are calculated by matching these segments. Also, a sequence of background images is calculated by spatially selective and time recursive averaging of the input image sequence in which the moving objects are not contained but in which other modifications of the background that are not caused by moving objects are contained. Further, a sequence of binary object masks is calculated by binarization of the difference image sequence from the input image sequence and the background image sequence using a threshold whose value is used for controlling the spatial selectivity in the calculation of the background image sequence and whose segments are determined together with their sizes and center of gravity positions. Finally, motion vectors of the detected objects are determined by minimization of the squared gray scale value differences averaged over the intersection of the shifted mask segments, whereby differences between the center of gravity vectors of corresponding segments are utilized as start vectors in the minimization.

Abstract: In a space diversity receiver, multiple signal paths are connected respectively to antennas (10a, 10b) for multipath reception. Each signal path includes a digital demodulator (11a, 11b) coupled to the antenna and an impulse response detector (15a, 15b) or autocorrelator connected to the demodulator for deriving a channel impulse response of each one of the multiple paths. A maximum response detector (16a, 16b) is connected to each impulse response detector for detecting equalizable delay components which give a maximum response value and a nonequalizable delay components. A power ratio of the nonequalizable delay components to the equalizable delay components is derived for each signal path and a minimum value of the power ratios is determined and one of the signal paths in which the minimum value is detected is selected. The output signal of the demodulator of the selected signal path is applied to one input of an equalizer, or a maximum likelihood sequence estimator (23) and the equalizable delay components of the selected signal path are applied to a second input of the equalizer.

Abstract: Polyamide granules are dried and heated by feeding a suspension of granules in water into a sieve (1), where the bulk of the water is removed, and then into a tower dryer (10), where they are deposited in bed form and then freed of the remaining water while moving in plug flow under the force of gravity with a counter-current inert gas stream at from 70 DEG  to 200 DEG  C. The tower dryer possesses an inlet at the top (11) and outlet at the bottom (34) for the granules and also feed lines (20, 22, 31) for the inert gas. To achieve a uniform degree of drying of the granules, the inert gas is divided on entry into the tower dryer at a point between the drying zone and the heating zone into a stream which flows radially inward into the bed of granules on the one hand and a stream which flows radially inward and outward on the other. In this way the inert gas is distributed particularly uniformly and the granules are dryable in a very short drying zone down to a water content of 0.0001 kg of water/kg of polymer. The lower, conically tapered area of the tower dryer-bin 30-ensures a uniform rate of descent of the granules and hence a uniform solid-phase condensation with a favorable molecular weight distribution. The tower dryer (10) is followed by a fluidized bed cooler (41) in which the granules are cooled with air to <50 DEG  C.

Abstract: In a radio communication apparatus in which an audible tone is generated (21-22) in response to reception (15-17, 19) of either a primary or a secondary call signal and stopped by a reset switch (23), the audible tone is stopped (172, 18) when the secondary call signal is received. When the primary call signal is received, the audible tone is not stopped unless the reset switch is continuously closed during a predetermined time interval. Alternatively, the audible tone is stopped when the reset switch is twice closed although the audible tone is produced again after the audible tone is stopped when the reset switch is once closed. As a further alternative, the audible tone is stopped in response to repeated closure of the reset switch without being again produced when the reset switch is once closed.

Abstract: The present invention is directed to improving the peel strength of copper foil laminated to polyetherimide substrates which optionally are reinforced. The improvement in process comprises coating one side of the copper foil with an adhesive composition, placing the coated side of the copper foil in contact with pre-formed polyetherimide substrate, and heat-pressing the resulting build-up to form a cured laminate of improved peel strength. The adhesive composition utilized comprises a blend of a polyvinyl butyral resin, one or more resole resins, and an organic solvent. Heat-pressing conditions comprise a temperature ranging from about 450° to 550°F and pressing conditions ranging from about 100 to 700 psi. Within this temperature/pressure range, the adhesive-coated copper foil mated with the pre-formed polyetherimide substrate yields desired peel strengths without inducing excessive flow of the polyetherimide substrate, i.e. maintaining a pre-desired thickness ± 7.5%.

Abstract: A method of quantitative analysis of products, such as barite, bentonite or polymers, in a drilling fluid circulating in a wellbore being drilled is described. The method comprises the steps of sampling the drilling fluid, and analysing the sample to determine the density of the fluid and the weight fraction of solids in the fluid. In addition, a known weight of the sample is dried to constant weight so as to obtain the products under the form of solids, which solids are analysed by an infrared spectroscopy technique. The concentration of the products in the drilling fluid is then determined. The method can be applied to the control of the drilling operation by monitoring the quantity of products added to the drilling fluid, such as barite and polymers, or a product coming from the borehole wall or the underground formation being drilled. The invention also applies to the control of the working condition of the mud solids equipment.

Abstract: A polyester preform which is injection molded preferably of PET and wherein the preform is provided with a molded neck finish or neck portion including threads which are molded to a high tolerance and wherein the neck finish may receive a closure cap of the type having a tamper indicating band which engages over a retaining bead also molded to a high tolerance as part of the neck finish. In order to maintain the container which is blow molded from the preform in axial alignment with the neck finish and thus eliminate the perpendicularity problem, a ring of the preform immediately below the flange which functions as the capping ring, is heated to a high temperature and crystallized. In a like manner, the end sealing surface is also heated to a high temperature and crystallized. The remainder of the neck finish remains in its amorphous state without disturbing the configuration of either the threads or the retaining bead. This combination of crystallized portions with the remainder of the neck finish remaining amorphous assures a high quality connection between a closure cap, whether the closure cap is formed of plastic or metal, while providing the end sealing surface with a hard tough finish resisting deformation and at the same time reducing the closure cap removal torque.

Abstract: The workpiece feeding means is operated from a main drive shaft which is driven by a motor (M1) in response to drive signals supplied by computer control means, the value of which signals depends upon the value of a signal supplied to a computer control means by a transducer (T) incorporated in a foot treadle. Moreover, in order to ensure that the actual speed matches the desired speed, the rotation of the drive shaft is monitored and any appropriate compensation then made by the computer control means. Provision is also made for varying the range of speeds within which the machine will operate, such variation also being achieved by the computer control means such that, for any given setting of the transducer, the particular feed speed will be varied proportionally; this means that the overall travel of the treadle will be constant regardless of the width of the speed band. Provision is further made for setting, through the computer control means, feed lengths for "normal", "snipping" and "pleating" operations and for storing a combination of selected feeds lengths as a style pattern for subsequent recall. In addition, for varying the feed length during a cycle of operation a stepping motor (SM1) is provided and the computer control means is effective to "phase in" any feed length over a pre-determined number of rotations of the main drive shaft. Any variation of the feed length from the "normal" setting, furthermore, serves to vary the adhesive supply rate by a proportion determined by the relationship between the selected feed length and the "normal" feed length as set.
