IPC: E05F15/16
Filed: 1993-06-23
Abstract: A door operator (11) for a reversibly operable door (12) includes a frame (14) and a carriage (24) movably mounted on the frame (14) and attached to a door (12) for moving the door (12) between open and closed positions. A drive member, specifically a roller chain (21), extends along the frame (14) and moves the carriage (24). A drive train is provided within a housing (32) and is connected for moving the drive member, and a control circuit (36) is provided for controlling the drive train to open and close the door (12). A pair of limit switches (61,62) is mounted within the housing (32) and connected to the control circuit (36) for stopping the drive train when the door (12) has reached a completed position. A pair of limit cams (50,51) are adjustably mounted on a limit wheel (47) within the housing (32) and separate from the carriage (24) for engaging the limit switches. The limit wheel (47), which is separate from the drive member (21), is connected to the drive train to rotate when the drive train moves the carriage (24). The placement of limit switches and associated connecting wiring along the frame (32) in the garage ceiling is eliminated. The limit cams (50,51) can be easily and automatically positioned on the limit wheel (47) by pushing a single switch without any manual movement of the limit switches or of the movable cams that contact the limit switches. <IMAGE>

Title: Target movement compensation for laser surgical system
Inventor: FOUNTAIN WILLIAM D
IPC: A61F9/008
Filed: 1992-02-19
Abstract: A system and method for detecting, measuring and correcting for movements of a target (14) in a medical analytic or surgical system (10) utilizes generally the principles of confocal microscopy.  A pinhole (42) and photodetector (46) combination is positioned behind optics (12) of a system for delivering an ophthalmic surgery laser beam (24), for example. As in a confocal microscope, the optics are arranged such that a beam waist (44) is formed precisely at the pinhole (42) when the target (14) is in its nominal position. When the target (14) moves from its nominal position in the depth direction, the signal from the pinhole/photodetector combination decreases. The change in the signal can be used to drive the objective lens (12) of the optics so as to move with the moving target (14). Alternatively, the signal can be used to drive the pinhole/photodetector assembly so as to again attain peak signal, in this way allowing the target's shift to be measured.

Title: Discharge lamp, particularly cold-start fluorescent lamp, and method of its manufacture
Inventor: HARZIG CHRISTIAN
IPC: H01J9/04
Filed: 1993-10-07
Abstract: ABSTRACT OF THE DISCLOSURE.    The lifetime of cold-start fluorescent lamps is increased, and the ability to withstand repeated ON-OFF switching cycles enhanced by coating the electrodes with an emitter which con-sists of barium oxide and a small portion of metallic barium and, optionally, up to 20 mol-% of strontium oxide and a small portion of metallic strontium, preferably only up to about 5 mol-% of strontium oxide - metallic strontium.  To make the emitter,       barium carbonate, optionally mixed with strontium carbonate, is applied in paste form to the electrodes which, when coated, are introduced into an envelope and sealed therein.  The envelope is then evacuated, and the electrodes are heated, thus converting the barium carbonate to barium oxide and metallic barium, and the strontium carbonate, if present, to strontium oxide and metallic strontium, so that the electrodes will be coated with barium oxide,     optionally strontium oxide,     and metallic barium and optionally metallic strontium.  The evacuation and activating step can be carried out essentially simultaneously, by evacuating the envelope through a pump tube and heating the electrodes to above about 800°C by passing a current pulse therethrough.

Title: Methods and apparatus for molecular characterization
Inventor: FORD NORMAN C JR
IPC: G01N30/74
Filed: 1993-02-12
Abstract: A molecular characterization detector (8) includes a scattering cell (10) containing a sample for molecular characterization a light source (20) for directing a light beam through the cell (10) so that the light beam is scattered by the sample, optical elements (30, 32, 50, 52) for selecting from the scattered light a measurement beam (40) comprising light that is scattered by the sample from a predetermined portion of the cell (10) in a predetermined range of angles relative to the optical axis (22), and a detector (44) for detecting the measurement beam and providing an output electrical signal representative of the measurement beam. The detector (44) typically selects light scattered from a central portion of the scattering cell at angles in the range of 14° to 16° . A single spherical lens (18) is preferably utilized. As a result, interference from stray scattered light is minimized. A beam dump (24) attenuates the light beam after it passes through the scattering cell (10). Additional detectors (62, 70, 80) detect light scattered at 90° to the light beam. The outputs of the detectors (44, 62, 70, 80) are processed to provide molecular characterization of the sample.

Title: Bulldozer assembly
Inventor: ASAL JERROLD R
IPC: E02F3/80
Filed: 1994-08-17
Abstract: Abstract of the Disclosure Bulldozer Assembly It is desirable in many applications to have a bulldozer assembly that can be angled and/or tilted without having interference between elements of the bulldozer assembly and the machine on which it is mounted.  In the subject arrangement, a bulldozer assembly has a blade connected to a U-shaped frame through a universal connector.  The blade is angled by a pair of angle cylinders connected between the U-shaped frame and a pair of spaced apart angle cylinder brackets located on the blade.  The universal connector is connected to the blade generally midway between the pair of spaced apart angled cylinder brackets and generally aligned therewith.  The pitch of the blade is maintained at a preselected position by a pitch control mechanism and mechanically adjusted by the pitch control mechanism.  Since the pair of spaced apart angle cylinder brackets and the universal connecting joint bracket are in general transverse alignment and the universal connecting bracket is located generally midway therebetween, any tilting of the blade permits the connection points of the pair of angle cylinders to remain generally along their neutral axis. The subject arrangement provides freedom of angling and tilting of the blade without interference between elements of the bulldozer assembly and the machine.

Filed: 1994-09-22
Abstract: ABSTRACT OF THE DISCLOSURE A surgical needle assembly is disclosed for use in the introduction of a catheter into a blood vessel. The assembly includes a safety feature which shields the needle. The assembly is made up of a cannula having a proximal end and a blunt distal end. An axial lumen extends between the two ends. A cannula hub is secured to the proximal end of the cannula. A needle is snugly located axially in the lumen of the cannula. The needle has a proximal end and a sharp distal end. A needle hub is secured to the proximal end of the needle. A spring is provided for biasing the needle relative to the cannula such that the needle is normally in a first equilibrium position in which the cannula shields the distal end of the needle. The needle can be urged against the bias of the spring into a second position in which the sharp distal end of the needle protrudes from the distal end of the cannula. In the preferred embodiment a catheter assembly is mounted axially on the cannula such that the distal end of the cannula protrudes from the catheter. Also disclosed is a method of introducing a catheter into a patient. The method has the steps of: providing a needle having a sharp tip; providing a cannula having a lumen, such that the needle fits snugly coaxially inside the lumen of the cannula; providing a catheter such that the catheter is slidably mounted axially on the cannula; providing a biasing force on the needle such that the needle is in an equilibrium position in which the needle tip is shielded by the cannula; moving the needle against the bias such that the tip of the needle protrudes from the cannula; inserting the needle into a patient; releasing the needle such that the biasing force causes the needle to revert to its equilibrium position; sliding the catheter off the cannula; removing the needle and cannula from the patient.
