Abstract: D-4,276   C-3264 PRESSURE SENSOR ASSEMBLY       Abstract of the Disclosure A pressure sensor element comprising a silicon chip having a diaphragm formed therein with piezoresistive strain responsive resistors is mounted in a housing of molded polyester material having a much different temperature coefficient of expansion than the chip.  The chip is protected from thermally induced and other stresses by a mounting arrangement comprising a glass base secured to the housing by a soft adhesive which largely prevents stress being transmitted from the housing to the base, wherein the base has a short pedestal on which a glass die is mounted which, in turn, supports the silicon chip. The short pedestal adds localized rigidity to the base so that any stresses in the base are taken up outside the region of the pedestal.  One face of the glass die is bonded to the base by a relatively soft epoxy to further inhibit stress transmission and the silicon chip is securely bonded to the opposite face of the die.  Contacts on the silicon chip are wire bonded to conductors which are insert molded in the housing.

Abstract: ABSTRACT:      In many heat exchangers is used a system of a large number of glass tubes, which are endwise connected with opposed holder plates, and it is hereby a problem to achieve an easy mounting of the tubes and at the same time a sealed, but non-stiff connection between the tube ends and the holder plates. According to the in-vention an advantageous connection is achieved by pro-ducing the holder plates  as moulded elements e.g. made of an artificial resin, with the use of a mould having a plurality of upstanding core stubs each provided with a seat groove     for an O-ring . Prior to the moulding operation an O-ring is mounted on each of the stubs      and by the mould-ing operation corresponding seat grooves      will be formed in the moulded member. When the moulded member is rejected from the mould the O-rings      will remain in the moulded seat grooves and thus be drawn off the stubs      whereafter the moulded member is immediately usable for receiving tube ends through the moulded holes      and their associated O-rings     .

Abstract: ADAPTIVE FILTER INCLUDING A FAR END ENERGY DISCRIMINATOR            Abstract of the Disclosure An energy discriminator is employed in conjunction with an adaptive filter to control updating of the filter transfer function characteristic.  Specifically, the discriminator is employed to distinguish whether any significant received far end energy is only partial band or whole band.  If the received energy is partial band the adaptive filter is inhibited from updating the transfer function characteristic during intervals that such energy is being received.  On the other hand, if the received energy is determined not to be partial band and, hence, is whole band, the filter is enabled to update the transfer function characteristic during intervals that such energy is being received.          In a specific example, the discriminator is employed in an adaptive echo canceler to inhibit updating an echo path estimate being generated by an adaptive transversal filter when partial band energy is being received and enabling updating of the echo path estimate when whole band energy is being received.

Abstract: ABSTRACT OF THE DISCLOSURE         Electrical resistance variation in a sensor element is generated by fabricating the element from a metal oxide ceramic material, embedding electrodes in the sensor element, and decreasing the porosity of the sensor to decrease the rate of variation of electrical resistance as a function of partial pressure of oxygen in the environment of the sensor element.   The sensor is the then placed at a temperature above 700°F in an environment wherein the partial pressure of oxygen varies, so that the electrical resistance of the sensor varies with the partial pressure of oxygen.

Abstract: Application of MYRON A. BEIGLER and HAL C. DANBY      for A DEVICE FOR THE INTRAVENOUS OR ENTERIC INFUSION OF LIQUIDS INTO THE HUMAN BODY AT A PREDETERMINED CONSTANT RATE           ABSTRACT OF THE DISCLOSURE A portable device for accurately metering a liquid for intra-venous or enteric infusion into a patient's body in which the pressure from a pressure source is utilized to pressurize the liquid and the pressurized liquid becomes 'he sole driving force to meter and to infuse the liquid into the body.  The pressurized liquid is applied alternately to one of a pair of flexible liquid bladders the other one being connected to a discharge means so that, as one liquid bladder is filled with pressurized liquid, the other bladder is emptied into the patient.  The expanding liquid bladder and the contracting liquid bladder cooperate with a teeter totter type control means which applies pressure to the contracting liquid bladder and is damped to control the rate of expansion and contraction.  The position of the teeter totter controls the means for applying pressurized fluid from one side to the opposite by alternatively selecting channels of fluid flow to each liquid bladder  The means for damping the control means is in the form of a pair of flexible damping bladders connected through an adjustable constant flow valve which is disposed on the side of the teeter totter type control means opposite the  liquid bladders.

Abstract: ABSTRACT       A method and a device for correcting the cuff pressure in the indirect, non-invasive and continuous measurement of the blood pressure in a part of the body by using a plethys-mograph in a fluid-filed pressure cuff, an electronic control circuit, and an electric pressure valve.  The cuff pressure is controlled by the plethysmographic signal in closed-loop operation with the aid of a servo-reference level obtained via a memory circuit.  The servo-reference level, in opera-tion of the device, is adjusted by opening the closed loop of the control circuit for a short interval, after which, in open-loop operation the cuff pressure is adjusted at an intermediate pressure derived from the pressure last measured and the servo-reference level is adjusted via the memory circuit.

Abstract: ABSTRACT OF THE DISCLOSURE         A vessel with a tabular, flexible handle.  The body of the vessel is integrally provided with upper and lower mounts which serve to attach the handle to the vessel.  A means for preventing the upper end of the handle from downwardly slipping out of the upper mount and a means for preventing the lower end of the handle from upwardly slipping out of the lower mount are formed integrally with the handle.  The tabular handle occupies little space when attached to the vessel by allowing the lower end of the handle to downwardly pass through the upper mount and then through the lower mount.  Since the total length of the handle is greater than the distance between the upper edge of the upper mount and the lower edge of the lower mount, the handle can be picked out so as to become bow-shaped.  Then the means for preventing the upper and lower ends of the handle from slipping out of the upper and lower mounts engage with the upper and lower mounts and thereby secure the handle to the vessel.

Abstract: ABSTRACT OF THE DISCLOSURE Optical fiber cladding compositions, based on highly fluorinated monofunctional acrylates, yield hard clad fibers that have attenuations often below 10 dB/km and whose temperature behavior is superior to silicone plastic clad silica (PCS).  The numerical aperture (NA) of the fiber can be varied by selecting a particular composition.  The main components of the composition are (1) a highly fluorinated monofunctional acrylate with a refractive index below 1.38; (2) a trifunctional or higher acrylate that serves as a cross-linking agent; (3) a mono or polyfunctional thiol that functions as a synergist; and (4) a photoinitiator such as an ultraviolet (UV) initiator.  These com-ponents can be varied relative to one another over a wide range, but the fluoroacrylate must always be the major component.  Where the fluoroacrylate is a solid at room temperature, a small amount of solvent like di-isobutyl ketone or methylene chloride can be added.
