Patent CA-2056563-A1 (CA)
Title: Interference type low voltage optical light modulator
Inventor: GNEHM CHRISTOPHER M
IPC: G02F1/01
Filed: 1991-11-28
Abstract: Abstract of the Disclosure A pair of fiber optic cables (12, 14) are connected at one end to a single light emitting diode (10).  The second ends of the cables (12, 14) are connected to a first end of a polarized polyvinylidene fluoride film member (16),  in a symmetrical relationship on opposite sides of a longitudinal centerline. The second end of the film member (16) includes a triangular recess formed by intersecting 45° edges  (82,  84).   A beam splitter (18) is positioned in the recess, with opposite end portions, one positioned to receive a beam of light from cable (12) and the other positioned to receive a beam of light from cable (14).  The beam splitter redirects the two beams towards each other and towards a diagonal split (72) at the center of the beam splitter (18).  A change in length of the film member (16) on one side of the longitudinal centerline will change the phase relationship of the two light beams where they meet at the split (72).  A fiber optic cable (20) is connected to the beam splitter (18).  The two light beams either cancel each other  out or combine  to produce  a  stronger  light  beam. Whichever condition occurs is received by the cable (20) and transmitted to a light analyzer (22).

Title: Method of attaching appendages to blow moulded products
Inventor: SCHWOCHERT HANS
IPC: B29C65/66
Filed: 1990-03-15
Abstract: In a method for creating a blow moulded product comprising the steps of extruding a parison tube (3) into a cavity formed between opposite halves of a mould (5), pinching off end portions of the parison via crimping apparatus (7 and 9), admitting high pressure compressed gas into the inner portion of the parison tube via a gas blow pin or needle (11) for inflating the tube against the opposite halves of the mould and thereby create the blow moulded product, the improvement comprising the steps of projecting an undercut dowel (13) from an inner wall of at least one of the opposite halves of the mould such that the parison forms around and conforms to the shape of the dowel, retracting the dowel into the wall thereby leaving an undercut in the parison in the shape of the dowel, removing the blow moulded product from the mould and inserting pin portions (19 and 21) of an appendage (17) into the undercut prior to cooling of the parison whereby the undercut shrinks around the pin portions during cooling to form a secure connection of the appendage to the product.
Patent CA-2060300-A1 (CA)
Inventor: HENDERSON SCOTT
IPC: A61B17/06
Filed: 1992-01-29
Abstract: A retainer for a suture having a suture strand and a needle attached to one or to each free end of the strand.  The retainer has as many as five panels foldably connected together. When all of the panels are folded, the retainer has the approximate size and shape of a first one of the panels.  The suture is contained within the folded panels.  A  separator on the first panel prevents tangling of the suture strand during withdrawal, facilitates such withdrawal, and, where multiple sutures are retained, keeps their respective strands separate. The separator may be one or more two-leaved, low friction and robust envelopes or an accordion-folded sheet of a low friction, robust material.  Alternatively, the separator may be one or more sinuous cuts in the first panel which define adjacent tabs and beneath which the strand may be frictionally held.  A suture-withdrawal site resides at one end of the first panel.  The second panel, at the other end of the first panel, is foldable to prevent the strand from residing beyond the boundary of the first panel and when so folded may overlie a part of the separator.  The third panel is foldable about a side of the first panel to overlie the folded second panel, the separator and the suture and to complementarily overlie the first panel, while not overlying the withdrawal site.  A holder, which may be a foam strip with or without slits and mounted to the first panel, frictionally (where it has slits) or mechanically (where it does not have slits) holds the suture strand to maintain the needle and the needle-strand attachment at the withdrawal site.

Abstract: This invention relates to a method and apparatus for establishing connections over a public switched telephone network to a customer whose telephone number is in a block associated, for routing purposes, with a first telephone switching system, but who is actually served by a second telephone switching system. The facility for carrying out this method is desirable in order to serve customers who need the advanced functions of a digital switching system, who are currently served by an analog switching system, and do not wish to have their telephone number changed when they switch to being served by the digital switching system. In accordance with the invention, a centralized database is queried to find the identity of the switch serving the called customer. The database returns a routing index for routing the call to that switch.

IPC: B62D55/26
Filed: 1990-08-21
Abstract: The invention concerns a track with several bands (3) running parallel to the direction of travel and connected to each other in the transverse direction by a multiplicity of steel strips (1). The steels strips (1) are U-shaped in cross-section and have a U-piece (4) consisting of two sides (5,6) joined by a connecting piece (7) between them. The first side (5) extends round a bend (9) into a connecting arm (10) leading inwards and then round second bend (11) to a track blade (12) which is approximately parallel to the sides (5, 6) of the U-piece (4). The steel strip is designed to be both stronger and cheaper to manufacture. This is achieved by virtue of the fact that the second side (6) of the U-piece (4) is welded to the end of the first connecting arm (10) via an inwards-bent second connecting arm (14) to form, in the interior of the U-piece (4), a cavity (21) similar io a house in cross-section.

Filed: 1992-04-09
Abstract: Spectroscopically correlated light scanning microscopy Abstract The present invention relates to a process for producing and  correlating  light  microscope  images  and spectroscopic data resolved according to wavelength of a sample by scanning individual elements of the sample surface to be imaged  once  or  twice  with  a  confocal  scanning  light microscope,  launching a portion of the  light from the imaging beam path into a spectrometer and correlating the image data with the spectroscopic data by storing the spectroscopic data in a two-dimensional area,  with one dimension being used to store the measured spectrum of the individual  elements  and  the second  dimension  being activated by means of  the  light   intensity diffusely reflected  by  the  scanned  elements  or  by  means  of  a criterion obtained from the total data of the sample image by image processing.            The advantage of said process is that the potential of a confocal  scanning  light microscope and of  the  various spectroscopic processes may be fully exploited.     Le A 28 365-foreign countries

Title: Fail safe elevator governor rope emergency brake
Inventor: SHERIDAN WILLIAM G
IPC: B66B5/24
Filed: 1992-04-27
Abstract: Abstract The governor rope on an elevator is provided with an auxiliary  brake which  is a  fail-safe brake  and which operates to stop movement of the governor rope when the elevator car moves away from a landing with its doors open. The brake includes two rope gripper jaws in the machine room beneath the governor sheave, which jaws are held away from the governor rope by a solenoid so long as power is supplied to energize the solenoid.  When the power supply to the solenoid is interrupted, the jaws are released to fall by gravity toward each other to grip the governor rope.   The car emergency brakes  are thus tripped and movement of the car stops.  The brake may also be provided to control the counterweight governor rope.
