Title: Skate
Inventor: BRATLAND JAN
IPC: A63C17/18
Filed: 1987-03-25
Granted: 1990-12-04
Abstract: Abstract Known skates which comprise a shoe portion made of leather or solid plastic and a metal base are heavy, render little support to the foot and have great air resistance.  The skate according to the invention comprises a shoe portion, a ground touching portion and a transition portion which connects the ground touching portion to the shoe portion.  The shoe portion and the transition portion are made in one piece and form a shell.          The shell is a sandwich construction with a core made of foam plastic and outer layers made of plastic reinforced with glass or carbon fibres. The ground touching portion may be a metal section fastened by glue in a downwards opening groove formed in the transition portion and adapted to glide on ice, or rollers arranged in the groove and adapted to rotate about respective shafts fastened to the transition portion.  There is thus provided a very light skate which renders good support to the foot and has little air resistance.

Title: Signal processing to enable utilization of a rig reference sensor with a drill bit seismic source
Inventor: RECTOR JAMES
IPC: G01V1/36
Filed: 1987-12-29
Granted: 1991-03-05
Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus (10) for providing while drilling infor-mation  on  a  subterranean  geologic  formation  (28) includes a drilling rig (12) and a rotary drill bit (18) attached to the drilling rig (12) for providing seismic waves as it drills in the earth (16).  Geo-phones (20) are spaced from the rotary drill bit (18) in the earth (16) and receive in direct seismic wave paths (26) and seismic wave paths (30) reflected from the subterranean geologic formation (28) the seismic waves provided by the drill bit  (18).   A reference sensor (24) is located on the drilling rig (12).  The seismic signals sensed by the reference sensor (24) and by the geophones  (20)  are cross-correlated to separate the drill bit generated signals from inter-ference signals by combining the reference signals and the  signals  received  by  the  geophonas  (20).   The cross-correlated reference   signals  and  the   signals received by the geophones  (20) are separated into a first group of the drill bit generated seismic signals travelling to the geophones (20) in direct paths and a second  group  of  the  drill  bit  generated  seismic signals  travelling to the  geophones  (20)  in paths reflected  from the  subterranean  geologic  formation (28).  The cross-correlation provides a domain where drill bit generated energy can be distinguished from interference.  The two groups of the drill bit gener-ated seismic signals can then be used to image the subsurface seismically so as to improve the chances of discovering hydrocarbons.  The technique is applicable to land operations and to drilling from an offshore platform over water.

Title: Dynamic multiple instruction stream multiple data pipeline apparatus for floating-point single instruction stream single data architectures
Inventor: SCHWARZ ERIC M
IPC: G06F9/38
Filed: 1988-07-21
Granted: 1993-01-26
Abstract: ABSTRACT OF THE DISCLOSURE            A dynamic multiple instruction stream, multiple data, multiple pipeline (MIMD) apparatus simultaneously executes more than one instruction associated with a multiple number of instruction streams utilizing multiple data associated with the multiple number of instruction streams in a multiple number of pipeline processors.  Since instructions associated with a multiple number of instruction streams are being executed simultaneously by a multiple number of pipeline processors, a tracking mechanism is needed for keeping track of the pipe in which each instruction is executing.  As a result, a dynamic history table maintains a record of the pipeline processor number in which each incoming instruction is executing, and other characteristics of the instruction.  When a particular instruction is received, it is decoded and its type is determined.  Each pipeline processor handles a certain category of instructions; the particular instruction is transmitted to the pipeline processor having its corresponding category.  However, before transmission, the pipeline processor is checked for completion of its oldest instruction by consulting the dynamic history table.  If the table indicates that the oldest instruction in the pipeline processor should complete, execution of the oldest instruction in such processor completes, leaving room for insertion of the particular instruction therein for execution.  When the particular instruction is transmitted to its associated pipeline processor, information including the pipe number is stored in the dynamic history table for future reference.

Title: Expanding probe with expandable seals
Inventor: WEISS KARL
IPC: B21D39/20
Filed: 1988-07-25
Granted: 1992-11-17
Abstract: Abstract The invention proposes a fluid pressure loaded probe for expanding a tube in portions and for simultaneously fixing several outer design elements such as cams, bearings and gear wheels, comprising a basic cylindrical member as well as sealing members and spacer sleeves slid on alternately, with tube portions to be expanded being marked off from the tube portions remaining undeformed, by the sealing elements. In accordance with the invention, the probe is characterised by a device for bringing the spacer sleeves closer to each other axially while simultaneously compressing and radially expanding the sealing elements  for pressing them against the inside of the tube, and by means for limiting the axial travel of at least part of the spacer sleeves relative to the basic probe member. In this way we provide a probe which permits simultaneous expansion of individual tube portions in accurate positions accurately associated with slid-on design elements and which, while having a simple design, provides improved sealing as compared to prior art probes for expanding several portions; it ensures stability of the seals and is easy to introduce into the tube.
