Title: Minimizing debug information for global types in compiled languages
Inventor: HICKMAN KEVIN PAUL
IPC: G06F11/36
Filed: 1996-12-24
Abstract: The invention provides a technique for generating minimal debugging type information in a distinguished compile unit while still supporting the debugging of classes for which the distinguished compile unit is not, in this module, being built or debugged, where the debugging information for the classes has been previously compiled into one or more object modules. On detecting a reference to a type in a program, the compiler inserts code into the module it is compiling to direct the linker where to locate the debugging information object module describing that type. Usually, the object module will be located in a separate link library, so the compiler directs the linker to add the debug library to the list of libraries from which it tries to resolve symbolic references, and to add a reference to an external linkage symbol defined in the object module describing the type. The linker will have to resolve this symbol by adding the debug library into the link.

Abstract: A transmitting chain for an automobile electric window includes an endless transmitting chain, a lower gear, an upper gear, two lower chain protectors, two upper chain protectors, two elastic tubes and an elongate cover. The lower chain protectors contain the lower gear having a leaf connector to combine with a rotating mechanism, which rotates the lower gear. The lower gear then moves the chain, which then rotates the upper gear.      The upper gear then moves a lowering and lifting mechanism of the electric window of an automobile. The endless chain has its two intermediate portions contained in the elastic tubes and the elongate cover covers the tubes to hold them side by side.

Abstract: A light sensitive dimmer switch circuit for controlling the illumination level of a light as a function of the ambient illumination level surrounding the dimmer switch circuit by selectively controlling an AC power signal provided to the light includes a photocell and a phase control circuit. The photocell is responsive to the ambient illumination level and has a conduction state associated therewith. The conduction state changes, in response to the ambient illumination level, such that the photocell effectively exhibits either a substantially open circuit or a substantially short circuit. The phase control circuit selectively varies a conduction phase angle associated with the AC power signal which correspondingly causes a variation in the illumination level of the light. The phase control circuit, in response to the photocell, selectively varies such conduction phase angle and thus the illumination level associated with the light when the photocell exhibits an open circuit and, conversely, prohibits the AC  power signal from being provided to the light when the photocell exhibits a short circuit. Preferably, the phase control circuit permits the light to illuminate approximately at a full illumination level while the photocell exhibits a short circuit. Thus, the light sensitive dimmer switch circuit controls the light such that a user may operate the same in either an off region, a dimming region or a full illumination region.

Abstract: This invention relates to watches and more particularly to an improved electronic watch. It is a timing device which can count and display any chosen unit of time (for example: seconds, minutes, hours, days, months, years) in a continuous ascending or descending manner without any interruption, using the decimal system, with its recurring and resetting cycle of ten units (for example the invention can be continuously counting seconds without resetting to zero when the count of 60 seconds has beenreached, or can be continuously counting minutes without resetting to zero once the count of 60 minutes has been reached). Thence the invention provides a new possibility to time up or down, to or from events, and using a single time unit. Without anymore calculation needed, this timing device offers an unique way of keeping, at any instant, a permanent measure of the time left before reaching a precise moment - or a measure of the time gone since a precisemoment, or the measure of the time between two moments - while keeping and displaying continuously the same time unit, in a decimal way, this for commercial, promotional artistic, educational or scientific purpose or for use of any kind.

Title: Modulation of drug radiation resistant genes
Inventor: SCANLON KEVIN J
IPC: C12Q1/68
Filed: 1994-09-12
Abstract: The effects of suppressing c-<u>fos</u> oncogene expression on drug or radiation resistant mammalian cells are described. A2780S human ovarian carcinoma cells with resistance to actinomycin D were isolated and the resultant A2780AD cells exhibited the MDR phenotype. A hammerhead ribozyme designed to cleave <u>fos</u> RNA cloned into the pMAMneo plasmid was transfected into A2780AD cells. Induction of the ribozyme resulted in decreased expression of c-<u>fos</u>, followed by that of mdr-1, c-<u>jun</u>, and p53. Reversal of the MDR phenotype by the anti-mdr ribozyme occurred one-fourth as rapidly as that induced by the anti-<u>fos</u> ribozyme. These studies demonstrate the primacy of the c-<u>fos</u> oncogene in maintaining the resistant phenotype in human cancer cells. Thus, down regulation of <u>fos/jun</u> will make resistant cancer cells more sensitive to conventional treatment, i.e., cancer chemotherapeutic agents and/or radiation.

Title: Chemical anchor bolt and cap assembly
Inventor: GIANNUZZI ANTHONY C
IPC: F16B13/14
Filed: 1998-02-25
Abstract: A chemical anchor bolt and cap assembly installable in a hole drilled in masonry to tightly fasten a fixture thereto and to resist loosening of the fastening should the masonry be subjected to vibratory or other external forces. The assembly includes a bolt having an externally-threaded cylindrical shank coated with a release agent and a thin-walled hollow cap having a non-cylindrical shape coupled to the end of the shank and extending therefrom in axial alignment with the shank. To install the assembly, the shank and the cap coupled thereto are inserted through a mounting hole in the fixture into the masonry hole in which is deposited an uncured epoxy that then surrounds the cap and the shank.      When the epoxy hardens, formed therein is a female thread matching the release-coated male thread of the shank so that the bolt is now turnable, the cap being then embedded in the epoxy. As a consequence, formed in the masonry hole below the end of the shank is a hard epoxy column having a non-cylindrical cavity whose epoxy bank is defined and lined by the non-cylindrical cap to create a partial barrier to the unimpeded advance of the shank. To tighten the fastening, the bolt is turned to advance the end of the shank into the cavity, the shank then overcoming the partial barrier by cutting into and tapping the lined epoxy bank. The resultant frictional engagement between the end of the shank and the partial barrier acts to resist loosening of the fastening.
