Abstract: A package that protects an optical fiber from strain or controls the strain to which the fiber is subjected for a desired effect and a method for making thepackage are disclosed. The package is a sleeve with an internal passage in which a portion of an optical fiber is placed. The optical fiber and the sleeve are made of materials with coefficients of thermal expansion that are the same or different.If the coefficients of thermal expansion are the same, the package protects the fiber from certain strains brought about by a change in temperature that would otherwise result if the package and the fiber were made of different materials. However, by selectively mismatching the coefficients of thermal expansion of thepackage and the fiber, a change in temperature can be used to bring about a desired change in the wavelength of a grating written in the fiber. The optical fiber is fixed in the sleeve by epoxy or other adhesive means at least at one point in the internal passage of the sleeve.

Abstract: An axial locking device has locking balls (5) which engage in a groove (4) in a male member (2) to lock the male member (2) to a female member (1). To effect locking, a first axial movement of the male member (2) causes it to abut an end surface on a slider (8) and pushes slider teeth (9) against rotor teeth (11), and a return movement of the male member (2) allows the slider (8) and rotor (12) to return, pushed by a spring (13). In this way, the rotor (12) is caused to rotate and its internal cam surface moves the locking balls (5).     To reduce the number of pans and simplify manufacture, retaining teeth (10) are formed by U-shaped clips on the housing (6) of the female member (1), and act to prevent rotation of the slider (8) during its axial movement, and to prevent rotation of the rotor (12) until the rotor teeth (11) have cleared the retaining teeth (10), causing a click or snap action. During the return movement of the slider (8) and rotor (i2), the rotor teeth (11) cam over the ends of the retaining teeth (10) and continue to rotate the rotor (12) in the same direction.

Abstract: An improved one-sided embossing process for manufacturing low-fat non-stick frying cookware is provided.  The process provides a textured cooking surface free of sharp edges which increases the useful life of a non-stick coating applied thereto.          The embossed cooking surface of the resulting frying device comprises a series of wave-like grooves embossed in the surface of the pan.  The wave-like pattern of each groove is one-half cycle out of phase with its neighboring adjacent grooves to form an alternating pattern of outwardly extending lands and inwardly extending roots.  A raised portion or elevated surface is provided on the cooking surface disposed between the outwardly extending lands.  The elevated surface is the primary cooking surface and is further the location of the inevitable initial wearing of the non-stick material.  The remaining non-stick material, disposed in the grooves and between the roots is not subject to abrasive action and wears at a substantially slower rate.  The raised portions or elevated cooking surfaces disposed between the lands comprise less than 30 percent of the upper cooking surface and therefore less than 30 percent of the non-stick coating disposed on the upper cooking surface is exposed to the abrasive action of cooking utensils or cleaning utensils.

Title: Cold sterilant with extended active life
IPC: A61L2/18
Filed: 1994-07-12
Granted: 1999-03-09
Abstract: Sodium perborate is mixed with a mixture, preferably a 1:1 mixture, of a rapid acetylating agent, e.g. TAED, and a slow acetylating agent, e.g. acetylsalicylic acid, in water to form a biocidally effective peracetic acid solution. When sodium perborate and TAED alone react in water, peracetic acid is produced quickly but has relatively little stability and a short useful life (curve 10). When sodium perborate and acetylsalicylic acid are mixed in water, the peracetic acid solution takes an extended duration to reach maximum efficacy, but is stable for an extended duration (curve 12). The mixture of rapid and slow acetylating agents quickly produces a stable peracetic acid concentration (curve 14).

Abstract: A capillary sampling flow controller provides an improvement in the process of sampling or monitoring for the analysis of air and gas chemistries; a constant flow rate is used to introduce a specific volume of gas into a vessel or through a trapping media over the selected sampling period. The improvement employs calculated geometry of the capillaries employed to deliver the gas sample to the evacuated vessel. It can also include a pressure reading device installed between the vessel and the capillary, and a filter at the inlet. The length of capillary with available internal diameters is estimated mathematically and confirmed experimentally to achieve any sampling time using any size sampler.  The flow rate obtained from the controller is constant over its operating range and is designed to meet a specific sampling duration to obtain long-term integrated samples. The sampling process becomes completely passive, precise, reliable and simple to operate.

Title: Secreted .alpha.-amylase as a reporter gene
Inventor: HICKEY DONAL A
IPC: C12N15/62
Filed: 1997-04-24
Granted: 2008-01-15
Abstract: The regulation of gene expression is of fundamental importance to all biological functions including adaptation to environmental conditions, cell division and differentiation, and the development of disease states such as cancer. The application of "reporter" gene systems, which allow changes in gene expression to be assayed quickly and easily, has contributed greatly to our understanding of the mechanisms involved in gene regulation. Reporter genes come in two basic varieties; those that encode intracellular enzymes, and those that code for secreted reporter proteins. Most reporter genes currently in use are of the intracellular variety that require manipulation of the cells, normally harvesting and lysis, prior to measurement of the reporter activity. In contrast, cells transformed with constructs that encode secreted reporter enzymes do not require manipulation or lysis of the cells for activity measurements.  Instead, aliquots of the extracellular medium are harvested and assayed directly for enzyme activity. Thus, secreted reporter genes can be used to monitor gene expression in vitro, in vivo and ex vivo. The present invention relates to a reporter gene encoding the chicken a-amylase enzyme for use in transforming mammalian cells. The use of a-amylase as a secreted reporter gene is particularly attractive because the enzyme is extremely stable over a wide range of conditions, measurement of .alpha.-amylase activity is simple, quantitative, sensitive, safe and inexpensive, and the range of electrophoretically-distinguishable variants available allows the assays to be performed in virtually any host without interference from endogenous amylase activities.

Abstract: Fastening apparatus is formed of a drilling tool  for drilling an axially extending borehole in a receiving material.  The drilling tool  has a cutting member at its leading end and its trailing end  is arranged to be inserted into a chuck in a hand held drilling device capable of rotating the drilling tool and providing axially directed hammer-like blows.  A tubular fastening element has a bore extending between its leading and trailing ends and is arranged to be anchored in the borehole formed by the drilling tool.  The diameter of the bore in the fastening element is greater than the outside diameter of a cutting circle formed by the cutting member of the drilling tool. The drilling tool extends axially through the bore in the fastening element so that its cutting member projects from one end of the fastening element and its trailing end extends outwardly from the trailing end of the fastening element.  The drilling tool is rotated by the drilling device, however, the fastening element is not rotated.  While the borehole is being drilled by the drilling tool, the trailing end of the fastening element is contacted by the drilling device, directing hammer-like blow against the trailing end of the fastening element so that simultaneously the fastening element is driven into the borehole being formed by the drilling tool.  Due to its configuration, the fastening element is anchored in the borehole.  The fastening apparatus carries out a method of directly mounting the fastening element in a borehole, as the borehole is formed by the fastening apparatus.
