Abstract: A penetrating antibiotic gel for treating pain, inflammation and other pathological conditions affecting musculoskeletal tissues and other soft tissues of the body. The composition includes an antibiotic compound and a mobilizing agent in an amount sufficient to enable the antimicrobial compound to penetrate into the sub-dermal soft tissues. The antimicrobial compound may be a macrolide antibiotic compound such as azithromycin, erythromycin or roxithromycin, for example, and the mobilizing agent may be an organogel compound, such as pluronic lecithin liposomal organogel (PLO). The composition may further include a penetration enhancing adjuvant, such as d-limonene, for example. The composition may be applied topically so as to penetrate into the sub-dermal soft tissues, or may injected so as to be absorbed into the soft tissues locally.

Abstract: A convoluted, bi-metallic test strip is inserted between a battery and an electrical circuit within a flashlight having a nonzero, quiescent, current drain. Squeezing the test strip permits consumers to temporarily test the flashlight. The strip is then removed by consumers after the flashlight has been purchased.

Abstract: A baseboard assembly is designed for installation in a junction region where a lower edge of a generally vertical wall meets a side edge of a generally horizontal floor. The assembly includes a base portion and a top portion. The base portion has a back surface and an opposed front surface. The base portion also has a lower end and an upper end. The base portion is configured to be positioned in the junction region, with the back surface against the wall and the lower end adjacent the floor. The upper end of the base portion is sloped downwardly from the front surface to the back surface. The top portion has a back surface and an opposed front surface. The top portion also has a lower end and an upper end. The lower end of the top portion is sloped downwardly from the front surface to the back surface. The top portion has an installed position wherein the back surface is adjacent the wall and the sloped lower end is adjacent the sloped upper end of the base portion.

Abstract: A coextruded zirconium tube and tube liner are monitored along their lengths by well known ultrasonic measurement techniques that are modified by the blocking out of extraneous signals at opposite sides of a timing gate that varies in width according to variations in the width and shape characteristics of successive points along the length of such coextruded tube and liner. The blocking of such extraneous signals enables a normally very weak signal representing the interface between tube and tube liner to be identified and used, together with a group of stronger signals representing the inner surface of the tube liner, in monitoring tube liner thickness and characteristics by a sonic wave traversing the distance across the timing gate.

Abstract: A read channel circuit includes a high frequency filter and a pair of differentiators, one of which is a high resolution differentiator and the other of which is a low resolution differentiator intentionally adjusted to perform its differentiation function imperfectly. Comparators serve as zero crossing detectors for the high and low resoltuion signals. The comparator for the low resoltuion path provides the data input to a flip-flop. The comparator for the high resolution path has its output processed by an exclusive OR gate and a delay circuit before being applied to the clock input of the flip-flop.

Abstract: Digitally encoded information is stored on a data track in an improved format characterized by a leader field followed by a data field and a trash gap at the end of the data field. On a rotatable disk storage medium, the leader field has a randomly selected starting point which may change each time a new set of data is recorded on the track. The leader field contains encoded control information which signals the beginning of the ensuring data field. The trash gap may contain spurious data remaining from a previously recorded set of data and is maintained shorter than the leader field at all permissible rotational speeds of the disk to prevent spurious data on the trash gap from being erroneously recognized as valid leader field control information.

Abstract: An infrared detector assembly comprising a substrate of suitable material such as sapphire, an infrared detector array attached to the substrate, a cold shield attached to the detector array, and an optical microphonics filter attached to the cold shield is disclosed. The optical microphonics filter includes a substrate of material having its major surfaces coated with layers of thin film coatings for passing a preselected frequency band, and a metalization for reflecting spurious energy impinging thereon thereby shielding the filter's substrate and coatings therefrom.

Abstract: A method and apparatus for implementing the same are provided for digitally synchronizing the timing of a sequence of electrical output pulses in accordance with a selectable, permissably non-linear function of the timing of a sequence of electrical input pulses. The method and apparatus are illustrated with reference to application thereof to overcoming the problem of degradation of synchronization caused by so-called "peak shift" due to the adjacent data effect in the reading of binary data stored on magnetic disks or the like. Pulses of a timing reference signal having a uniform interval equal to a sub-multiple of the normal average interval of the desired output pulses are continuously counted to a number base equal to the denominator of said sub-multiple, and output pulses are produced whenever a pre-selected count value occurs. Output pulse timing correction values in accordance with the synchronizing function selected are stored in memory.
