Title: Endovascular splinting devices
Inventor: VIDLUND ROBERT M
IPC: A61B19/00
Filed: 2001-10-02
Abstract: A method for placing a splint assembly transverse a heart chamber includes providing an elongate member having a first end and a second end and a deployable heart-engaging assembly connected to at least the first end. The method includes advancing the elongate member through vasculature structure and into the heart chamber such that the first end of the elongate member extends through a first location of a wall surrounding the heart chamber and the second end extends through a second location of the heart chamber wall substantially opposite the first location. A deployable heart-engaging assembly is deployed such that it engages with a first exterior surface portion of the heart chamber wall adjacent the first location. The elongate member is secured with respect to the heart with a second heart-engaging assembly connected to the second end. The second heart-engaging assembly engages with a second exterior surface portion of the heart chamber wall adjacent the second location. A splint assembly includes an expandable heart-engaging assembly formed partially from portions forming the elongate member of the splint assembly. A delivery tool includes a tubular member configured to be advanced through vasculature structure and has a curved distal end.

Title: Device for measurement of the speed of dissolution in depth of resists
Inventor: MADZHAROVA NIKOLINA A
IPC: G03F7/004
Filed: 1991-05-17
Abstract: The method is applicable in microlithography and has expanded functional capabilities. It layers and dries the sample resist and measures its initial depth, and various areas are irradiated with different doses. Then follows repeated treatment in an oxygen plasma and the residual thickness after each plasma treatment is measured. The speed of plasma etching at the respective depth is determined, then a radiation dose is selected, when the in-depth speed change will be the smallest. The speed values are used for inspection of an existing model or for development of a new model for the lithographic process, as well as for evaluation of the expected image profile, especially when there is no model for a concrete technological cycle.

Inventor: WASLEY ROBERT S
IPC: G01M3/04
Filed: 1989-10-11
Abstract: A sensing assembly suitable for detecting both a first event which involves the presence of an electrolyte and a second event which does not involve the presence of an electrolyte, and for distinguishing between them. The assembly comprises a first conductor and a second conductor which is electrically insulated from the first conductor in the absence of both first and second events but becomes electrically connected to the first conductor by either an ionic connection in the presence of a first event or an electronic connection in the presence of a second event. The assembly also comprises a sensing apparatus of determining whether the connection is ionic or electronic. The assembly is useful for detecting leaks of hydrocarbons, e.g. gasoline, and water in storage tanks.

Patent CA-2008596-A1 (CA)
Inventor: DROGE BERNHARD
IPC: B60J7/057
Filed: 1990-01-25
Abstract: The invention concerns a device for controlling a drive mechanism, e.g. for windshield wipers, wiping/washing systems,  sliding roofs  and the tops  of motor vehicles dependent on how moist or dirty the windshield is on the outside.  With help of a sensor and a special computation circuit, the degree and type of moisture or dirt can be ascertained.  Depending on whether or not there is only a fine mist or a heavy thundershower, the appropriate circuits on the  windshield  wipers,  sliding  roofs  or  tops  are automatically  actuated.    If  dirt  is  detected  on  the windshield, then a wiping/washing system is switched on.          Sudden splashes on the windshield, which appear just before the last wiping action of a wiper is completed, are detected and lead to a new wiping action.

Abstract: FREIGHT CONTAINER            Abstract of the Disclosure In order to secure small and medium-size containers having a width of e.g. 2200 mm to locking members as provided at a standard lateral spacing of 2259 mm on vehicle platforms designed for transporting ISO containers, such small or medium containers are equipped with double-fittings (12) each com-prising two openings (13) and projecting beyond the width dimension of the container. The center-to-center spacing of the two openings (13) is 280 mm and thus corresponds to the distance of pairs of locking members which are provided on such platforms for engaging adjacent corner fittings of two ISO containers placed behind each other. By the simultaneous coupling to such pairs of locking members, safe securing with better distribution of forces is achieved also for containers that are shorter than the shortest ISO container.

Title: Process for purifying products containing esters of a non-reducing sugar and one or more fatty acids
Inventor: VIANEN GERARDUS M
IPC: B01D11/00
Filed: 1990-06-22
Abstract: A B S T R A C T   The  invention  relates  to  a  process  for  purifying  crude  products containing esters of a non-reducing sugar like sucrose, and one or more fatty acids such as palmitic acid, stearic acid etc. by subjecting said crude  esterification  products  to  an  extraction treatment  with supercritical  carbon  dioxide.  After  carrying  out  this  extraction treatment a residue comprising the fatty acid esters of non-reducing sugars,  the  unreacted  sugar  and  the  salts  as  well as  an  extract comprising  the  fatty  acids,  fatty  acid  alkyl  esters  and  also  any solvents,  if present,  are obtained.  The unreacted sugar and salts, present in the obtained residue, can be removed from said residue by, for example, a washing operation resulting in a final product of pure esters of the non-reducing sugar and one or more fatty acids. This last removal  step  concerning the unreacted sugar and salts may also be carried out before the application of the above indicated extraction treatment with supercritical carbon dioxide.

Title: Optical attenuator
Inventor: TAMAMURA HISASHI
IPC: G02B27/28
Filed: 1990-07-03
Abstract: Abstract An optical attenuator includes a first beam splitter for receiving an incident light beam from a light source at a predetermined angle of incidence and splitting it into a first reflected light beam and a first transmitted light beam, and a second beam-splitter for receiving the first reflected light beam at the same predetermined angle of incidence and splitting it into a second reflected light beam and a second transmitted light beam.  The first and second beam splitters are arranged such that the planes of incidence of the first and second beam splitters are perpendicular to each other.  The optical attenuator further includes a first deflector for deflecting the first transmitted light beam to cause the deflected light to be propagated in other than the incident direction of the first transmitted light beam.  A second deflector is also provided to deflect the second transmitted light beam to cause the deflected light to be propagated in other than the incident direction of the second transmitted light beam.

Abstract: A low power consumption timing device using an oscillator and chained CMOS flip-flop devices providing all time-dependent functions, with an audible and/or visual alarm which signals after a predetermined elapsed time and continues until deliberately reset especially useful for repetitively timed events such as reminders for taking medication at fixed intervals. When reset the elapsed timer begins the next timed interval. A minor circuit revision, makes possible an automatic reset of the timer mechanism after each elapsed interval without disturbing the signal latch. This alternate method can produce constant period cycles without regard to other signal reset mechanisms.

Abstract: The three-way valve has a chamber in the body which is adapted to provide a connection from an outlet passage to both inlet passages. One inlet passage is closed by a valve lid which bears on a valve seat and which functions as an automatic outlet valve when the armatures moves into a top position. The other valve lid moves independently in dependence on the inlet pressure of the second inlet passage and the pressure in the outlet passage. In the illustrated rest position, the armature acts by way of a convex closure member to press the lower valve lid onto a valve seat about the second inlet passage.
