Title: Apparatus for laying curved lines in an ice rink
Inventor: GILKES ROBERT R
IPC: A63C19/10
Filed: 1990-10-03
Abstract: ABSTRACT OF THE DISCLOSURE          APPARATUS FOR LAYING CURVED LINES IN AN ICE RINK             An apparatus for laying curved lines in an ice rink comprises a guide pole having a fulcrum pin at one end so that the pole can rotate about a centre of an intended circular line.  On an opposed end of the guide pole is mounted a reel of a paper material which can unroll across the ice as the opposed end  rotates  around  the fulcrum pin.    A guard  member for protecting  the  reel  includes an end plate against which an outer  surface  of  the reel  slides and a side plate along a peripheral surface of the reel to prevent water from a spray from  engaging  the  reel  and  causing  freezing  of the  paper material  onto the reel.   The guard member  includes the end plate and a rectangular side plate with a lower edge of the rectangular side plate resting upon the ice surface to act as a smoothing agent for the paper as it is laid.   The device is pushed around the circle by a handle attached to the end of the guide  pole  with  the  handle  including  a  spray  nozzle  for applying a fine mist of water onto the paper immediately after it is laid upon the ice surface.

Title: Code reading
Inventor: APTER ROBERT
IPC: G06K7/10
Filed: 1991-07-11
Abstract: ABSTRACT OF THE DISCLOSURE           A process for reading a chain of code characters which is arranged annularly on a transparent bottle in the bottom area of the same,  by photographing at least the bottom area of the bottle through the bottle neck by means of a camera and simultaneously illuminating the bottom area of the bottle from below.   With a zero relative speed of rotation between camera, bottle and illumination source, a snapshot of the bottom area of the bottle with the complete code character chain is taken from the inside of the bottle with the camera and is stored as an image for the later decoding of the code character chain.   The code-reading process is a very rapid process, because the fraction of a second in which the bottle is in a line with the camera and the illumination source is adequate for reading the code. The evaluation of the image of the code character chain which is photographed occurs using a histogram technique by comparison with a stored annular pattern which is divided into sectors.

Title: Axial inlet beam-type compressor
Inventor: BEAR CLAYTON
IPC: F04D29/04
Filed: 1991-12-23
Abstract: Axial Inlet Beam-Type Compressor ABSTRACT OF THE DISCLOSURE          A rotary fluid machine suitable for transferring energy between a fluid and a rotor assembly is disclosed. The rotor assembly is comprised of a shaft carrying one or more impellers which are located between axially spaced radial bearings in a beam-type arrangement. The rotary fluid machine is of the beam type - i.e. it has one end of the shaft extending beyond one end wall of the housing and one end of the shaft terminating within the housing. Two passages are formed in the housing to allow fluid to flow in and out of the machine. One passage is formed in the housing parallel to and co-axial with the rotational axis of the rotor assembly. Fluid moving between the passage parallel to and co-axial with the rotational axis does not have to be redirected thus reducing fluid turbulence and improving machine efficiency.

Title: Multiple access communication system capable of deciding a connection route among a central station, repeater stations, and terminal stations
Inventor: ARAI KOJU
IPC: H04J3/00
Filed: 1992-02-26
Abstract: In a multiple access communication system comprising a central station, at least one repeater station, and at least one terminal station, each of the central, the repeater, and the terminal stations has each station number.  The central station transmits a central downward signal comprising a central number signal representative of the station number of the central station to the repeater station.  The repeater station separates the central number signal from the central downward signal.          The repeater station transmits a repeater downward signal comprising a repeater number signal representative of the station number of the repeater station to the terminal station.  The terminal station separates the repeater number signal from the repeater downward signal as a separated repeater number signal.  The terminal station transmits an upward signal to the repeater station.  The upward signal comprises the separated repeater number signal and a terminal number signal representative of the station number of the terminal station.  The repeater station receives the upward signal and transmits to the central station a central upward signal which comprises the central and the repeater number signals, and the separated and the terminal number signals.  A central processor (106) carries out a process operation by the use of a combination of the central and the repeater number signals and a combination of the separated and the terminal number signals.

Title: Electrosurgial instrument with extendable sheath for irrigation and aspiration
Inventor: PARINS DAVID J
IPC: A61B1/00
Filed: 1992-10-21
Abstract: ELECTROSURGICAL INSTRUMENT WITH EXTENDABLE SHEATH FOR IRRIGATION AND ASPIRATION           ABSTRACT OF THE DISCLOSURE      An electrosurgical instrument having a protective, extendable and retractable sheath or sleeve is disclosed. The sheath is disposed around and coaligned with an elongated cylindrical rod, from which extends at least one electrode.  A conductor extending from the electrode is  joined to  a  conventional  power  supply  cord  for connection to a source of RF voltage.  Power supply is regulated using  either  a  conventional  hand  or  foot switch.     The sheath protects the distal electrode(s) as the instrument is inserted through a laparoscopic trocar or endoscope.  It also provides an effective extension of an irrigation/aspiration  lumen  which  extends along  the length of the cylindrical rod.  The proximal end of the irrigation/aspiration lumen is joined to a supply tube which either may be connected to a fluid reservoir for irrigation or to a collection reservoir for aspiration of fluids.   Alternative  embodiments  feature  alternative mechanisms for extending the sheath.  In one embodiment, the sheath is retractable and shields the electrode(s) only when placed in a distal, extended position.  When this sheath is disposed proximally, the electrode is exposed for use.  When the sheath is disposed distally, it permits fluid travelling through the irrigation lumen to be delivered more precisely to a region of tissue, because  the  projection  of  the  electrode  no  longer interferes with placement.  In another embodiment, the cylindrical rod-shaped housing on which the electrode resides is retractable.   When the cylindrical rod is withdrawn to a proximal,  retracted position with the sheath,  it  shields  the  electrode  and  extends  the effective end of the irrigation lumen.
