Inventor: VOGELSANG HORST
IPC: H02G9/06
Filed: 1993-06-11
Abstract: An electrical conduit is substantially circular and is internally formed with zig-zag ridges.  The ridges are angularly equispaced and have portions of constant pitch a joined at corners, and the ridges contact a cable in the conduit at regions K each defined by the formula:                             Ar = 0.16b2zL K, where A  =   the surface of area R, equal to between 4,5mm2 and 32mm2, r  =   the radius of the conduit or D/2, b  =   the width of the contact region K, z  =   the number of ridges 1, and L K =   axial length of each ridge straight portion. The straight-portion pitch g in radians is equal to: g = r'al L K and is between 0.0o1rad and 1.2rad, radius r being equal to between 12mm and 100mm and L K is between 500mm and 10,000mm, depending on the diameter of the cable which can range from 5mm to 45mm.

Title: Tether for headpiece
Inventor: MORPHET EDWIN E
IPC: A42B7/00
Filed: 1993-06-14
Abstract: ABSTRACT OF THE DISCLOSURE             Wearing apparel headgear has a wide variety of styles for both adults and children.  When worn they are prone to being blown off.  This is particularly true for caps with peaks used in sports activities and for hats with brims used for dress.  In this invention a tether cord is used in which one end is clipped onto the headpiece and the other end is anchored to the upper body clothing by a clip. Alternately the two ends of the tether cord may be clipped to the headpiece and the loop passed under the chin.  The lower end of the loop may be either clipped to the clothing or closed tightly under the chin with a slip ring.  The risk of losing a blown off hat, the need to secure a cap by hand, and the disconcerting fear of a hat blowing off are all eliminated.

Abstract: A COMPUTER METHOD AND SYSTEM FOR CONSERVATIVE-STACK AND  GENERATIONAL HEAP GARBAGE COLLECTION               Abstract of the Disclosure A  method  and  system  for  conservative-stack  and generational  garbage  collection  for  a  computer  memory  is provided.    In a preferred embodiment,  the  computer memory includes a stack and a heap.  The heap comprises a plurality of objects each of which is identified as new or old.  During run time, a list of old objects that contain pointers to new objects is maintained.   During garbage collection time, each new object that is accessible through an old object in the list is marked as accessible.  The stack contains a plurality of stack entry that may be pointers to new objects.   During garbage collection time, each stack entry is checked to see if it could point to a new object.  Each new object that a stack entry could point to is marked as accessible and each new object that is accessible through the marked objects is also marked  as  accessible.    During  memory  compaction,  the  new objects that are not marked as accessible are reclaimed.

Title: Prosthetic heart valve
Inventor: BOKROS JACK C
IPC: A61F2/24
Filed: 1993-09-10
Abstract: Bi-leaflet heart valves (10, 91) have valve body contours and pivot arrangements that create quick valve response to flow reversal. Valve members or leaflets (14, 95), which can have flat or curved inflow and outflow surfaces, are slidably and pivotally mounted in a heart valve body (12, 93) of contoured profile so they can be aligned precisely parallel to blood flow in the open position. The leaflets engage either projections (26, 28) extending radially inward from flat wall sections (24) in the valve body sidewall or grooves (101, 103) in flat wall sections (117). The shape and relationship of these interrogating surfaces, together with a centrally directed surge of backflowing blood which results from the strategic location of a pair of downstream side openings provided by recesses (45, 114a) in the annular valve body, cooperate to provide prompt closing rotation of the leaflets from a parallel open orientation.

Title: Test apparatus for seal members in a pressurized oxygen environment
Inventor: HASEIMAIER L HAYNES SR
IPC: G01M3/28
Filed: 1994-01-10
Abstract: ABSTRACT            An apparatus for testing seal members for use in an oxygen-rich environment.   The test apparatus operates  and is constructed to replicate the service environment as closely as  possible.   The  test unit  includes  a hull  with  an interior test portion,  with connections  for gaseous or liquid oxygen and nitrogen and having  a  reciprocating actuator shaft extending into the hull interior.  A valve seal member is carried on a retainer and bears against sealing  surfaces  on  a  nozzle  to  test  valve  sealing operations, while a dynamic O-ring bears against a liner element  carried  within  the  hull.    Pressure  sensors determine whether an effective seal is maintained, while a temperature  sensor  insures  that  the  dynamic  O-ring temperature does not exceed specifications.  The retainer and the nozzle can be changed to permit testing a variety of valve seals.

Title: Identification of a data stream transmitted as a sequence of packets
Inventor: WENDORF JAMES W
IPC: H04N21/236
Filed: 1994-01-25
Abstract: The contents of a digital data file, interspersed as packets of data in a bit stream containing entertainment signals and/or other data files, are quickly identified without a high system overhead for identification of each packet. The data file is divided into packets, and sequential groups of packets making up the file are identified as segments. The first packet of each segment has a prefix containing a service identification number, a block number, a segment number, and possibly segment length information, followed by data contents. The following packets of the segment have only the service identification number and block number, followed by the data contents. Where the file data are transmitted repeatedly, often without change in many segments, receiver processing time or power can be greatly reduced by including a version number or toggle bit in the segment prefix, so that a receiver can ignore the unchanged data.

Title: Apparatus for interconnecting electrical contacts
Inventor: JOHNSON DAVID A
IPC: H01R12/71
Filed: 1994-04-29
Abstract: Apparatus for electrically interconnecting a lead of an integrated circuit device to a terminal spaced at a distance from the lead, such as on a printed circuit board. The apparatus is also useful for interconnecting two printed circuit boards. The apparatus includes a housing which has at least two flanges extending therefrom. The flanges are spaced a distance with an elastomeric element captured thereby and extending therebetween. A conductive contact is mounted on the elastomeric element and thus freely suspended for contact with terminals to be interconnected. A multiplicity of such contacts may be arranged in a suitable pattern for interconnecting specified integrated circuit devices with a printed circuit board. The contact shape can be generally disk-like to provide maximum wiping action and to facilitate airtight contact between the terminal and interconnect apparatus.
