Title: Process for controlling an injection molding machine
Inventor: HEHL KARL
IPC: B29C45/76
Filed: 1993-06-02
Granted: 2001-10-23
Abstract: Computer based interactive control of a plastics injection molding machine during input of portions of a production sequence and configuration of an injection cycle, which is effected essentially before the onset of the injection molding process. For a mold guided by an operator, operating parameters required for a process sequence are input by way of an input unit into a computer based control unit storing these operating parameters. Subsequently, one or a plurality of injection cycles are implemented according to the stored operating parameters. A physically possible production sequence, as well as a production sequence that is structurally specific to the machine and the tool employed, including any peripheral devices provided at the respective machine or associated therewith, is determined with the control unit. An operator is provided with a selection of possible inputs of further portions of the production sequence that can be added to the existing portions and are compatible with the machine and the tool based on the determination.

Granted: 2006-01-03
Abstract: A system and method for seam tracking in real time without path preprogamming uses as least two degrees of freedom and at least one degree of freedom created by a redundant axis.     A robot can be used to weld or apply adhesive or sealant to a workpiece that is mounted on a positioner that it is movable relative to a base of the robot as a movable end of the robot tracks a seam on the workpiece. A sensor expresses a seam trajectory in workpiece coordinates and queues the coordinates in a computer processor so that the coordinates can be extracted from the processor to cause the movable end of the robot to track the seam. The workpiece can remain stationary and the robot base can be moved or the base can remain stationary and the workpiece can be moved or both the workpiece and the robot base can be moved.     Any reasonable number of redundant axes can be utilized so long as there is one control parameter independently defined for each degree of freedom greater than six. Previous seam tracking systems do not have more than one degree of freedom with one of the degrees of freedom being created by redundant axes and previous systems do not automatically move the robot base relative to the workpiece.

Abstract: This invention relates to rapid set, medium set, and slow set anionic emulsions prepared from straight bitumen or bitumen modified by the incorporation of polymers, solvents, or polymer latices.  Particularly, the invention relates to improved methods for enhancing adhesion between the asphalt and the aggregate in anionic solventless and solvent-containing bituminous emulsions wherein the emulsifiers are alkali earth salts of tall oil fatty acids, fortified tall oil fatty acids, tall oil rosin and fortified rosin as well as combinations of kraft lignin and nonionic emulsifiers.  The adhesion promoters utilized in these improved methods are the reaction products of styrene (.alpha.-methyl styrene)-acrylic (metacrylic) acid polymers with polyalkylene amines.          Further improvement can be obtained by using tall oil fatty acid or fortified tall oil fatty acids as co-reactants in the production of the polyamidoamine products.

Title: Range repeater for a transmission system
Inventor: MYER ROBERT EVAN
IPC: H04B7/15
Filed: 1997-11-28
Granted: 2001-01-23
Abstract: The invention is a repeater for a telecommunications transmission system such as a CDMA wireless system. The repeater reduces leakage by means of a feedback signal whose amplitude and phase are adjusted in response to the amplitude and phase of a sampled input signal when a switch turns off the normal output of the repeater for a short period of time. In one embodiment, a pilot signal is transmitted during this time period so that the sampled input is the leakage signal. In another embodiment, the sampled input is the normal transmission signal received during the time period.

Title: Locking mechanism for a spring-actuated device
Inventor: SCHYRA MICHAEL
IPC: A61M11/00
Filed: 1996-12-05
Granted: 2005-07-12
Abstract: A spring-actuated output drive device is used for example in medical aerosol therapy for a miniaturised high-pressure producing device for atomising a small dose of a liquid medicament. A locking stressing mechanism for such an output drive device is to be stressed with the application of a relatively small amount of force and is to be released with one hand and is to operate reliably over a prolonged period of time. The locking stressing mechanism comprises a force step-up transmission means, for example a screw thrust transmission means, for stressing the spring, an annularly arranged locking member with engaging locking surfaces, two abutments for limiting the travel of the spring and a release button. It is compact, economical to produce, easy to assemble and comprises components with a low rate of wear. It can be reliably and easily handled by unskilled persons, even when high spring forces are involved. A medicament to be atomised can thus be metered with a very high degree of accuracy.
