Abstract: A communication apparatus is provided for transmitting and receiving a plurality types of data with a TDM slot, changing the type of the data by switching a mode.   The communication apparatus includes mode switching unit 101 and data dividing unit 102.  The mode switching unit 101 judges whether  a  length  of  the  second  data  is  less  than  a predetermined  value  when  it  detects  a  necessity  for transmitting the second data during a transmission of the first data.   If  less,  mode switching unit  101  inserts  a non-acknowledgement-type mode switch directive in the time slot data and transmits the time slot data by an interrupt.  The data dividing unit 102 identifies the second data included in the received time slot data if it is judged that the received time slot data includes  the non-acknowledgement-type mode switch directive,  and processes the data according to the identification.

Title: Biosensor with biomaterial covalently fixed on a signal-active surface
Inventor: THUST MARION
IPC: G01N27/414
Filed: 1995-09-30
Abstract: The successful bonding of bioactive material, especially enzymes, to the signal-active surface of a biosensor can be achieved by means of a heterobifunctional crosslinking agent having a group A reactive for the signal-active surface, e.g. a group reacting with -OH, -SH or -NHx, and a photoactivatable, biomaterial-reactive group B. Known groups B are, in particular, azidophenyl and azidosalicylic groups. Crosslinking agents containing such groups B on the one hand and succinimide ester groups on the other are commercially available and hence particularly attractive. The signal-active surface can be especially a Si3N4 surface with reactive NHx groups, as can be obtained from the gas phase by SiH4/NH3 reaction, especially on a fresh SiO2 surface, and has been freed from oxides especially by treatment with dilute hydrofluoric acid.

Abstract: Selon un mode de réalisation, la présente invention concerne un procédé de traitement de travail d'annulation concernant une transaction comme s'il s'agissait d'un travail sur l'original. Ce procédé permet de s'assurer que les articles de journalisation ont été fusionnés sur le disque (22, 24) et que les articles de journalisation éventuellement perdus sont détectés de manière fiable. Le procédé permet également de déterminer si une demande de mise à jour qui vient d'arriver est arrivée trop tard, ce qui fait que les transactions arrivées prématurément n'ont pas été traitées. Selon un autre mode de réalisation de l'invention, un bloc de commande de transaction (40) "présence d'incident" est utilisé. Une fonction offre la possibilité de créer une structure de données du bloc de commande transaction dans une UC (12, 14) dans le cas où ce type de structure n'existe pas encore.

Title: Method and apparatus for measuring axial and torsional loads on a valve stem
Inventor: SMITH CHRISTOPHER PAUL
IPC: G01L5/00
Filed: 1996-03-01
Abstract: An optical system for determining the axial load, the torsional load or both on a generally cylindrical member, such as a valve stem in a motor operated valve, includes a first system for producing a test light that is modified by a physical change in the valve stem caused by the load, a second system for receiving the test light and converting the same to a first signal indicative of the physical change, and a third system for converting the first signal to a second signal indicative of the load, preferably by utilizing one or more of the relations defined in Equations 1-3. The physical change in the cylindrical member can be, for example, a diametrical change or a longitudinal change, which can be measured by the first and second systems. The dimensional changes can be related to the axial load according to Hooke's Law or Poisson's relation by the third system when material properties and the geometry of the cylindrical member are known. Similarly, the torsional load applied to the cylindrical member can be obtained by measuring the twist angle between two longitudinally separated planes of the member, and applying a known relation between the twist angle and known geometric and material characteristics of the cylindrical member.

Title: Container having a tamper evidency system
Inventor: ODER REUBEN EARL
IPC: B65D55/02
Filed: 1996-02-20
Abstract: A tamper evidency system (10) for a container (12) having a closed body, an open ended finish portion (18), and a closure (14) to close the open end of the finish portion. The closure has a top and a depending wall portion (16) which has cam teeth (26) extending inward toward the finish portion. A lug (24) extends from the outer surface of the finish portion, located between the finish portion and the cam teeth when the closure is installed. The lug (24) is integrally molded to the finish portion by a shearable web (25). The shearable web (25) has an orientation, which enables the lug (24) to be rotated about the shearable web by the cam teeth (26) without interfering with installation when the closure is installed onto the finish portion. The lug also engages one of the cam teeth when the closure is removed from the finish portion. The lug (24) prevents the closure from being removed without first shearing the lug from the finish portion at the shearable web (25). The lug is unreachable for manipulation without the use of tools. In addition, the lug (24) has a corner (31) which contacts the outer surface (20) of the finish portion (18) when one of the cam teeth rotates the lug in a closure removal direction. The lug (24) pivots about the corner (31) upon contact with the finish portion to create a mechanical advantage for shearing the lug (24) from the finish portion at the shearable web (25). The tamper evidency (10) system may further comprise a flag (32) extending from the lug outside the open end of the closure in order to be visible to a consumer before the lug has been sheared off. Alternatively a lug (54) and shearable web (55) are integrally molded with a closure (44), and engaging cam teeth (56) are formed on a container finish (48).

Abstract: A two stage gas pressure regulator (10) with a body housing (12) having a gas inlet (14) and a gas outlet (16), and a common interior wall (28) dividing the body housing (12) into two chambers (24, 26), forming two pressure reducing stages. Respective intersecting fluid passageways through the common interior wall (28) communicate the first stage to the second stage and provide a gauge pressure tap (18) on the body housing (12), the intersecting passageways meeting at an intersection point within the common interior wall (28). Respective diaphragms (38) are provided for each stage, and a cover has a vent venting the volume defined between the cover and the second stage diaphragm. A small passageway is provided in a common cover wall (20) between the two stages, the small passageway being sized to suitably vent both cover portions above the respective diaphragms through the vent while eliminating overpressurization of the second stage in the event of pressure regulating failure of the first stage. A diaphragm actuated lever arm (76) includes a slotted end (78) with the slot matching a stepped gas flow controlling disc (80). The disc (80) is stepped to match the lever end slot so as to trap the disc within the lever slotted end. The inlet orifice in one or both of the regulator stages can be formed by casting and without further machining or additional orifice components.
