Granted: 1992-01-28
Abstract: BAIL-OUT CATHETER     Abstract A catheter for maintaining the patency of a blood vessel damaged during the course of angiography or angioplasty procedures comprising a toroidal coil whose adjacent turns are tightly wound and in contact with one another over a majority of the length thereof but which are separated from one another over a predeter-mined longitudinal dimension near the distal end thereof.  The tightly wound touching coils may be covered with a Teflon coating and when the catheter must be used to maintain patency in a coronary artery, it is advanced along the guide wire of an angiography or angioplasty catheter until the open turn portion of the bail-out catheter bridges the site of the damaged vessel.  After the angiographic or angioplasty catheter and its guide wire are removed, the bail-out catheter remains in position so that blood can flow through the open turns of that catheter and beyond until such time as surgical repair can be made.

Patent CA-1328573-C (CA)
Inventor: IWATA SATOSHI
IPC: B41J35/00
Filed: 1988-06-15
Granted: 1994-04-19
Abstract: ABSTRACT OF THE DISCLOSURE      When a print line is printed on a printing paper by supplying a print current to a thermal head, heating elements within the thermal head and a transfer ribbon are easily adhered together due to melted ink on surface of the transfer ribbon.  Due to such adhering between the heating elements and the transfer ribbon, a white line is easily formed on a printing paper.  In order to prevent such white line from being formed, the heating elements must be prevented from being cooled down after printing each print line.  More specifically, in a period between a first time when each print line is completely printed and a second time when a printing paper is to be transported forward to a next print line, the heating elements are heated by relatively small heating value which is sufficient to melt a adhering portion formed between the heating elements and the transfer ribbon but which is insufficient to perform the printing.  Thus, the heating elements are prevented from being adhered to the transfer ribbon, so that each print line can be printed with accuracy and without forming the white line.

Abstract: A B S T R A C T :            It has been  found long ago that taking samples from an impure granular material by means of a simple tubular sampling spear does not provide for any representative result, and a substantial improvement has already been obtained by embodying the spear     with an inner suction pipe      and an outer blower pipe     , said pipes being open towards one another at the spear end through an annular slot      for obtaining that the material which is let in through the spear tip is conveyed away by the suction air to a material separator      without showing any associated disturbing "vacuum cleaner effect" outside the spear mouth. With the invention, a small hole      is provided in the wall of the hose connection between the pressure side of the blower and the spear, through which hole a weak air flow will be blown out, whereby a correspondingly weak air intake will occur through the open end of the spear, and hereby a considerable improvement of the sampling accuracy is obtained. It may even be important to arrange for a similar, but smaller hole in the suction connection to the spear in order to reduce the vacuum at this place.

Granted: 1992-04-28
Abstract: A HIGH-SPEED DEMULTIPLEXER CIRCUIT Abstract A demultiplexer for demultiplexing a multiplexed input data signal into M output channels using M sequencer means clocked from an overlapping M phase system clock. The system clock operates at a frequency equal to the input data signal rate divided by M. Each sequencer means is clocked by a unique combination of the M phase system clock signals to select one data channel from the multiplexed input data signal. Since all sequencer means circuits are synchronized to the system clock, no variable delay lines are needed to align the timing between the circuit stages. A time delay latch is provided where needed in each sequencer means to enable all channels to output data concurrently. The demultiplexer includes a real-time data-framing capability to assure that the input data is correctly mapped to the proper output channels.

Filed: 1989-01-30
Granted: 1992-10-13
Abstract: Abstract of the Disclosure In a method for tagging members of a large group of macro-organisms so that each macro-organism is assigned to a respective subgroup, successive segments of wire are cut from a continuous length of wire indelibly marked along the length thereof with a sequence of separate and distinct identification codes each including a respective multidigit numeral with individual digits disposed in a linear array extending in a longitudinal direction along the length of the wire.  Each multidigit numeral is flanked on opposite sides in the longitudinal direction by other multidigit numerals of the sequence of identification codes and has exactly one digit differing in value from a corresponding digit of a multidigit numeral on one side and exactly one digit differing in value from a corresponding digit of another multidigit numeral on another side.  During implantation, a tag is ejected and stored to define the beginning of a set of successive tags corresponding to a subgroup of macro-organisms. The tags of that subgroup are then severed from the length of wire and implanted into respective members of the particular subgroup.  Subsequently, another tag is severed from the wire and stored to mark the end of the subgroup.  Upon capture of a member of a subgroup, the tag is excised, the respective multidigit code is read and compared with the multidigit codes of the stored tags to determine to which subgroup the captured macro-organism belongs.

Granted: 1995-01-17
Abstract: Packaging machine, especially for cigarettes. For the supply of web-like packaging material to high-performance packaging machines has hitherto involved a high outlay in terms of labour.  The packaging material has to be fed to the packaging machine in the form of reels and in the region of this conveyed up to a working journal.  Manual involvement has hitherto been needed for this.  For the fully mechanical transfer of reels, from a reel stock to one of two working journals, the transport journal mounted on a transport arm is used.  The transfer of the reels from this onto a working journal is carried out by means of the axis-parallel displacement of a catch, in particular of a push sleeve actuated by the transport arm.  Furthermore, a reel core of a reel which has run empty is stripped from the working journal by means of the transport arm and tube strippers mounted on this.  The supply of reels of packaging material to the packaging machine takes place here completely automatically and without any manual involvement.
