Patent CA-1320883-C (CA)
Title: Surgical fixation pin tension adjuster
Inventor: FISCHER DAVID A
IPC: A61B17/84
Filed: 1987-04-16
Granted: 1993-08-03
Abstract: ABSTRACT           A tension adjuster is mounted on and is part of an  external  fixation  device  comprising  frame  segments rigidly supporting fixation pins that pass through  and immobilize fractured bones during rehabilitation.   This tension adjuster securely attaches the fixation pins to the frame segments and adjustibly applies tension along the fixation pins to more ridigly secure the fixation pins and to improve the immobilization of the fractured bones. The tension adjuster comprises a threaded slotted screw attached to the fixation pins and comprises a mounting nut having an aperture through which is drawn the threaded slotted tension screw while adjusting the tension along the fixation pins.   A tapered pin extending into the aperture of the mounting nut and into a chamfered slot of the threaded slotted tension screw,  guides the threaded slotted tension  screw through the mounting  nut  during tension adjustments.   A tension nut rotating upon the threaded slotted tension screw and buttressing the tension mounting nut operates by simple turning motion to draw the threaded  slotted  tension  screw  through  the  tension mounting  nut and  thereby  applying  tension  along  the fixation pins.

Abstract: Abstract of the Disclosure An optical recording medium in tape form which may either be strips of tape or reels of tape, all having preformatted continuous servo tracks from one end to the other.  Preformatted servo tracks are spaced-apart lines, so as to permit data spots to be written between or on the tracks.  The tracks may extend either longitudinally, parallel to the lengthwise direction of the tape or in a perpendicular direction, extending in directions trans-verse to the length of the tape, or in a grid-like pat-tern.  The tape web may be joined to a web of transparent protective material over the surface of the strip.  A data card may be made using a strip of such tape without regard to registration of the tape with markings on the card.  Tracks may be made by directly writing with a laser on direct-read-after-write laser recording material or by photolithography or by embossing.

Abstract: L-SHAPED BEARING ASSEMBLY          ABSTRACT          A  bearing  assembly  designed  to  preclude  the escape  of  lubrication  through  bushings  within  which elongated shafts are rotated at high speeds.  The bearing assembly is comprised of a bearing member of split-ring form which is made of a readily moldable self-lubricating material having a pressure velocity value at least equal to 1800  at 100 feet per minute  surface speed,  and is L-shaped in cross-sectional configuration.  It includes an elastomeric sealing ring mounted in supporting relation to the sealing portion of the L-shaped bearing member which is compressed therewith within a groove provided for that purpose at the outer end of the bushing.  The sealing ring maintains  the  bearing member  in  close-fitting,  sealing relation to the sealing surface surrounding the shaft and is insulated by the bearing member from the sealing sur-face having rapid relative movement and from associated parts to thereby obviate the normally attendant destruc-tive effects of high speed rotation upon such a ring.

Abstract: ABSTRACT      A security system for controlling access to property having  a  user  operated  keyboard to key in and reset a composite password code.   An indicator visually displays at  least  one  code symbol varying with time.   A memory device stores a current composite password code including at least two code symbols  so  that  upon  entry  of  the keyed-in  password code through the keyboard,  one of the stored password code symbols is replaced directly by  the time varying code symbol to form a regenerated, composite password  code  which  is then compared with the keyed-in password  code  to  grant  aces  to  the  property  when coincidence   occurs   between   the   keyed-in  and  the regenerated  password  codes.     In  response  to   non-coincidence,  an alerting signal is generated to indicate the incorrect password condition.

Abstract: ABSTRACT OF THE DISCLOSURE     The radio  system embodying  the invention comprises a central station and  a  terminal  station  or passive  end.  Data  signals  are transmitted  between  data  processing  units  which  are  respectively connected to the central and terminal stations. The radio system is essentially characterized in that the terminal station comprises a square two-dimensional antenna and a microwave switcher so as to phase modulate, by means of a data signal, a microwave transmitted from the terminal  station  to  the  central  station.  This  phase  modulated microwave is produced from an incident microwave transmitted by the central station and issued  to the terminal station by the square two-dimensional antenna. The design of the terminal station is very simple and compact and can be included, as well as the corresponding data processing unit, in a contact-free chip card.
