Abstract: In a first embodiment, arylene sulfide resins are provided by contacting, in a polymerization mixture, during a polymerization process, reactants comprising: an alkali metal sulfide, an organic amide, an alkali metal carboxylate, water and a monomer source which comprises at least one dihaloaromatic compound. The amount of alkali metal carboxylate present during the polymerization process ranges from about 0.002 to about 0.05 mole per each mole of sulfur present in the resulting arylene sulfide resin. The total amount of water present during the polymerization process ranges from about 1.02 to about 2.1 moles per each mole of sulfur present in the resulting arylene sulfide resin. In a second embodiment, arylene sulfide resins are provided by contacting, in a polymerization mixture, during a polymerization process, reactants comprising: an alkali metal sulfide, an organic amide, an alkali metal carboxylate, water and a monomer source which comprises a mixture of at least one dihaloaromatic compound and at least one polyhaloaromatic compound having more than two halogen substituents per molecule. The ranges of the amount of alkali metal carboxylate present during the polymerization process and the total amount of water present during the polymerization process are identical to those amounts disclosed in the first embodiment. The amount of polyhaloaromatic compound initially present ranges from about 0.0001 to about 0.01 mole per each mole of dihaloaromatic compound present prior to the initiation of the polymerization process.

Abstract: A method and apparatus for measuring a parameter of a test gas in isolation from gas pressure fluctuations. A pump draws the test gas through an air capacitor into a sensor, storing the gas in the capacitor. A valve closes a fluid flow path which admits the test gas to the air capacitor and opens a fluid flow path between the air capacitor and a constant pressure alternate gas source, isolating the air capacitor and the sensor from pressure fluctuations in the test gas. The air capacitor prevents any mixing of the test gas with the alternate gas until measurement of the unknown parameter has been accomplished.

Abstract: A demolition hammer intended for attachment to a bracket or the like. The demolition hammer includes an adapter bracket which connects to the arm of a backhoe in place of the conventional bucket of the backhoe, and a hammer head spaced apart from the adapter bracket by a hammer spring arm cantilevered or pivotably mounted with respect to the adapter bracket. Repeated operation of the backhoe hydraulic cylinder which normally pivots the bucket will instead move the hammer into repetitive impacts with the concrete or other work surface undergoing demolition. The flexibility of the hammer spring adds a whipping action which increases the effective impact of such movement.

Abstract: Radiation in the near infrared over a limited range of wavelengths about 1660 nanometers is projected on a portion (31) of the body, for example, the ear, of the patient. The resulting radiation emitted by the portion, either scattered from the portion or transmitted after absorption and scattered by the portion, is processed to derive an expression of the resulting radiation as a function of the wavelength. The second derivative of this function over a very narrow range of this function between 1640 and 1670 nanometers is expanded and the glucose concentration is determined from the magnitude, or intensity, of the scattered or transmitted radiation at the maximum or minimum point of this derivative. Also disclosed is apparatus for non-invasive determination of glucose concentration in the patient. Radiation in the near infrared is transmitted through a first fiber-optic radiation conductor (29) to the outer surface of a portion (31) of the patient's body, penetrating into the portion. A second fiber-optic conductor (33) transmits the resulting radiation emitted from the portion to data processing means (23) which produces the desired second derivative as a function of the wavelength of the incident radiation. The processor includes a spectrum analyzer (21) which produces a spectrum of the resulting radiation. <IMAGE>

Date Aug. 20, 1992.A method to be implemented in an integrated services network, such as the well known ISDN, GSM or CMS88 type networks, takes advantage of short message service technology to enable communication between terminal equipment units, i.e., between people using the network. This method makes possible (a) the use of a short message service to provide automatic answer transmission; (b) the use of a specified memory area, from which the content of the automatic answer transmission is automatically fetched; and (c) the storing, in advance, within the specified memory area, of any useful information for any potential caller, i.e., a calling subscriber. The calling subscriber will in turn automatically receive information, e.g., on how to reach the person not attending the terminal device for the moment, or any other such useful information. The short message service scheme permits the sending of short messages from a call originating device to a call terminating device, even when the user of the call terminating device is not answering the call.

Abstract: A first inflatable retraction device has a first inflatable chamber (5) and a non-pressurized chamber (13) inside the main chamber. The non-pressurized chamber is expanded by inflating a second inflatable chamber (25). The non-pressurized chamber enables the main chamber to remain inflated when an aperture is cut in the envelope of the main chamber, through which treatment is carried out. A second inflatable retraction device has an inflatable retractor (103) and a maintainer (107). The inflatable retractor retracts the organ and the maintainer maintains the organ in its retracted condition after the inflatable retractor is deflated. The maintainer can be inflatable, and can be inside or outside the inflatable retractor. A self-retracting endoscope (201) has an optical assembly with an expandable retractor (211) fitted to its distal end. The distal end of the endoscope is inserted into the body with the retractor in a collapsed condition. The retractor is then expanded to retract organs that would otherwise obstruct the view from the distal end of the optical assembly. After observations are complete, the retractor is returned to its collapsed condition. An insertion tube (243) enables cylindrical objects, such as packaged inflatable retraction devices, to be pulled, instead of pushed, into the body. The additional chamber of an inflatable retraction device having two inflatable chambers is filled with a slurry of a particulate solid in a liquid. The liquid is removed and the additional chamber evacuated to consolidate the particulate solid. This increases the retracting strength of the additional chamber. <IMAGE>

Abstract: Cuff electrodes (40a, 40b) are surgically implanted around S3 sacral ventral root nerve trunks (16a, 16b). The sacral ventral roots have smaller diameter nerve fibers (20a, 20b) which convey action potentials to cause detrusor activation to contract the bladder (10) and larger diameter nerve fibers (18a, 18 b) which carry action potentials for causing contraction of a urethral sphincter (12) to block the flow of urine from the bladder. A current source (50) causes current pulses (52) between such electrical contacts (46, 48) and a central electrical contact (44). The current pulses have an appropriate amplitude and waveform to initiate action potentials adjacent the central contact and to block the propagation of action potentials adjacent the end electrodes along the larger diameter nerve fibers (which have fewer nodes between the contacts) but not the smaller diameter nerve fibers (which have more nodes between the electrodes). In this manner, action potentials are electrically excited to propagate at least downstream on the smaller diameter nerve fibers causing contraction of the bladder. Concurrently, blocking action potentials are allowed to propagate upstream on at least the larger diameter nerve fibers, collision blocking naturally occurring action potentials propagating downstream. The transmission of action potentials downstream on the larger diameter nerve fibers is blocked by the current pulses allowing the urinary sphincter to relax.
