Patent CA-2100166-A1 (CA)
Title: Transdermal perfusion of fluids
Inventor: SVEDMAN PAL
IPC: A61M37/00
Filed: 1992-01-07
Abstract: Apparatus (150) has a housing (153) attached to the skin adhesively and defines a chamber (156) within which suction is applied at a treatment site. After formation of a suction blister the blister is disrupted to expose a dermis layer of skin from which the epithelium has been removed. Liquid drug is then introduced into the chamber for transdermal perfusion directly through the dermis. Suction is applied to the chamber without connection to an external source of suction by means of an evacuated cell (158) separated from the chamber by a disruptable membrane (167). A tubular member (164) is actuated to rupture the membrane, dis-rupt the blister and deliver liquid to the chamber in successive stages of operation of the apparatus.

Title: Metathesis of Acidic By-Product of Chlorine Dioxide Generating Process
Inventor: SCRIBNER HERBERT C
IPC: C01B11/02
Filed: 1992-04-21
Abstract: Sodium sesquisulfate produced in crystalline form in  a  high  acidity  methanol-based  highly  efficient chlorine  dioxide  generating  process  is  converted  by metathesis  to  crystalline  anhydrous  neutral  sodium sulfate and the acid recovered as a result is recycled to the chlorine dioxide generating step.

Title: Apparatus for driving both single-ended and differential computer buses
Inventor: FLEMING CAROLINE M
IPC: G06F13/42
Filed: 1992-01-15
Abstract: Apparatus and method for communicating between a plurality of devices on an electrical network (bus) that supports the Small Computer Systems Interface (SCSI) standard as described in American National Standards Institute (ANSI) SCSI-1 Specification X3T9.2 Rev. 17B. To communicate via the SCSI bus, bus controlling circuitry in a first device and counterpart circuitry in a second coupled device must conform to the SCSI standard which allows a particular SCSI bus to be one of two electrically different but functionally equivalent formats: single-ended or differential. To permit a device to communicate through either a single-ended or a differential SCSI bus, small adapter cards are used with a compatible SCSI bus controller board to communicate over either format SCSI  bus. The adapter cards come in two different types to allow single-ended or differential communication, respectively. The adapter cards are an inexpensive and easy way to adapt a device's SCSI bus control circuitry selectively to either a single-ended or differential SCSI bus.

Inventor: IKEDA CHINATSU
IPC: H04L12/54
Filed: 1994-01-04
Abstract: In an ATM network using a burst-level band-width allocation, a source terminal reserves, before a burst transmission, band-widths according to a peak rate of the burst and then sends the burst therethrough. When the transmission is finished, the band-widths are released. Where there exists a link to which the peak rate is not assigned.      NACK is sent to the terminal and the reserved band-widths are released. On receiving the NACK, the terminal allocates a band-width with peak rate lower than that of the first request after a back-off time is elapsed, thereby minimizing the block probability of the transmission. The source terminal declares a minimum band-width together with the peak rate (maximum band-width) in the band-width request operation.      Each node allocates the peak rate when the remaining band-width of a link controlled by the node is sufficient to allocate the peak rate. Even if the remaining band-width is insufficient, when the band-width is not less than the minimum band-width, there is allocated a band-width equal to or more than the minimum band-width and equal to or less than the peak rate according to the remaining band-width, thereby transferring the burst.

Abstract: ABSTRACT            There is disclosed a self-retracting and self-locking portable document storage system.  The system includes a top protective sheet and a bottom protective sheet which may be releasibly connected together.  The sheets comprise a material resistant to aging and light damage.   The system permits the document or documents stored between the sheets to be positioned therein without any damage to the document.  This is achieved, in one embodiment,  by employing hook and loop material which also provides an adhesive.   The system includes a hollow tubular structure within which  the  top and  bottom  sheets  and  any document(s) may be contained.  A spring roller arrangement is provided to assist in extension and retraction of a document positioned between the sheets.   The use of the hook and loop material has been found effective since this system does not impede the extension and retraction and thus does not damage the document in any manner.
