Title: Catheter set
IPC: A61M25/00
Filed: 1982-04-20
Abstract: In order to keep the opening for inserting a catheter into a blood vessel as small as possible, a catheter insertion tube is used which coaxially surrounds the puncturing canula and consists, at least in a circumferential area and/or at least along a portion of its length, of one or several dilatable or expandable areas permitting enlargement of its internal diameter. The diameter of the catheter insertion tube, at the front end where it is inserted into the blood vessel, is approximately equal or smaller than the outer diameter of the catheter. The catheter insertion tube is expandable at least over the front or forward portion of its length by the catheter. The catheter insertion tube i removable from the puncture over the catheter while the catheter is advanced into the puncture and is tighty sealed by the catheter because the catheter has an external diameter equal to or larger than the puncture previously occupied by the insertion tube.

IPC: H04N17/04
Filed: 1985-12-19
Abstract: A CRT calibration system is provided having a CRT with 
a display screen, an electron gun system, and a plurality of 
feedback elements. Each feedback element has an active 
area disposed proximately to the display screen at a 
preselected location such that an electron beam from the 
electron gun system can strike at least a portion of the active

element provides a feedback signal related to the area of the 
portion struck. The system also includes a detector system 
for detecting each feedback signal, and an integrating 
analog-to-analog converter which, in response, provides a 
digital signal related to the portion of the active area struck 
and thereby to the position of the electron beam relative to 
the particular feedback element interrogated. Also included 
is a control system for directing the electron beam to strike a 
sequence of portions of the active area for each feedback 
element, thereby evoking a corresponding sequence of 
feedback signals for each feedback element and a corres­
ponding sequence of digital signals, enabling the control 
system to determine the location of each feedback element.

IPC: H04N1/413
Filed: 1985-05-23
Abstract: An automatic picture coding system including a method 
for converting a bit-map image of the picture to vectors as the 
picture is being scanned. The bit map is delayed as it is being 
generated to form a series of tessellations or windows of data. 
The windows are propagated through a series of neighbor­
hood-logic elements which perform data transformation opera­
tions such as growing, smoothing and thinning of the bit-map 
image. A bit stream output from the neighborhood logic which 
output includes only line and edge features of the original pic­
ture is transferred serially to a microcomputer where the fea­
tures are partitioned into a plurality of line segments. Each line 
segment is chain coded and temporarily stored, as it is ac­
quired, in  a corresponding one of a plurality of lists, the lists be­
ing linked in an order corresponding with the order in which the 
segments are acquired. When the storage of each chain-coded 
segment is completed, the segment is converted to vectors and 
transmitted to a user device for display, storage, or further 
processing, the lists in which the converted segments were 
stored being unlinked and deallocated. The process is con­
tinued until the entire document has been scanned and con­
verted to vectorial data.

mechanically simple device which is immediately ready for use when a 
volume is positioned thereon.
