Abstract: DENTAL IMPRESSION TRAY ASSEMBLY AND   METHOD OF TAKING IMPRESSIONS                             Abstract An impression tray is provided with a dispersal member which receives impression material for delivery into the impression tray. A one-step method includes the provision of barriers on the impres-sion tray to confine light bodied impression material in the tray during the delivery of the material into the tray and the taking of the impression.  A two-step method entails the direct deposit of heavy  bodied impression material into the impression tray and the taking of a preliminary impression.  A jig for punching the prelimi-nary impression confines the impression tray during the formation of passageways for later injected lighter impression material injected into the dispersal member and then to the impression tray. An air cylinder is controlled by an operator for selective discharge of impression material from tubular containers and into the dispersal member.  A unitary impression tray is disclosed with a dispersion channel for directing impression material into place.

Patent CA-2120072-A1 (CA)
Inventor: TROTT ROBERT E
IPC: G03G15/08
Filed: 1994-03-28
Abstract: An electrophotographic apparatus in which toner particles are moved from the toner hopper or dispenser cartridge to the developer housing and onto the donor roller in a single component development system for use in color reprographic systems. A rotating holey tube toner agitator is modified to incorporate structure or grooves on the outer peripheral surface. Further, by placing a shrouded toner dispense auger inside the holey tube, the development system architecture stays compact and improved toner powder pushing through the pre-load of toner on the donor roller results, thereby insuring delivery of fresh toner evenly across the length of the developer housing. With more efficient pre- load, agitator rotational speed and bias can be reduced, leading to less toner effluents emanating from the developer housing without adversely affecting the cycle to cycle donor roller toner reload.

Title: Mold closing unit for use in an injection molding machine for processing synthetic materials
Inventor: HEHL KARL
IPC: B29C45/66
Filed: 1994-04-11
Abstract: ABSTRACT      MOLD CLOSING UNIT FOR USE IN AN INJECTION MOLDING       MACHINE FOR PROCESSING SYNTHETIC MATERIALS             In a mold closing unit for use in an injection molding machine for processing synthetic materials arranged on a mounting surface an electro-mechanical drive is applied in a toggle mechanism, at which the driving unit is movably held. The elctro-mechanical drive converts a rotational movement of a driving unit into a linear movement for the toggle. The lenght of the lever and the length of the driving element, formed as a double toothed rack, is less than the distance from the mounting surface to the link points. Alternatively a quill motor can be provided as driving unit. This arrangement allows that the linear drive and the mold closing unit can be of a shorter and more compact construction.

Title: Telephone answering device linking displayed data with recorded audio message
Inventor: KLAUSNER JUDAH
IPC: H04M1/27453
Filed: 1993-03-30
Abstract: A telephone answering device (TAD) (25) which includes a means of intelligently organizing voice messages, associated entered codes such as personal IDs and home telephone numbers, and information stored in the memory of the TAD. These codes or numbers are decoded by means of the caller entering DTMF signals into the telephone which are recognized, recorded and processed by the TAD. When processed with codes and personal information previously entered into the device's memory, the TAD displays (32) the identity of the callers for each message, thus providing a menu of choices, i.e., a list of callers. This enables the user to access messages in a selective manner based on the identity of the caller. The need to listen to the actual voice messages to determine the caller's identity and the need to listen to the messages sequentially or chronologically is obviated, saving both time and effort.

Title: Vehicle restraint
Inventor: ALEXANDER JAMES C
IPC: B65G67/02
Filed: 1991-01-10
Abstract: A vehicle restraint employs a 4 bar linkage to lift a restraining member to a position that engages a vehicle thus restraining it at a loading dock.  The linkage is upwardly based to hold the unit in an engaging position and may be retracted by using any of a number of mechanical techniques such as hydraulic electric or pneumatic power.          The 4 bar linkage transfers all loading on the unit from the ICC to the frame thus isolating any driven members from overloads.  A secondary hook mounted to the 4 bar linkage is pivotally spring loaded to limit vehicle travel away from the dock and to extend the capture range of the device in the case of ICC's bars that are damaged or mounted at non-standard positions at the rear of the vehicle.

Title: Multi-stripe array grating integrated cavity laser
Inventor: POGUNTKE KAI RALPH
IPC: H01S5/14
Filed: 1993-09-09
Abstract: An integrated, multi-wavelength laser having formed on a substrate (12) a plurality of active, individually selectable waveguides (14), a passive output waveguide (16), and a diffraction grating (18) formed in a Rowland-circle spectrometer geometry. The frequency of the lasing light is determined by the geometrical relationship of the selected active waveguide, the diffraction grating, and the output waveguide. The active waveguides are positioned such that lasing light cannot diffract between two active waveguides. Little crosstalk occurs because no carrier depletion occurs in the output waveguide.
