Title: Composite metal-plastic gear and method for making same
Inventor: ANDERSON MARVIN ROBERT
IPC: F16H55/17
Filed: 1982-09-01
Granted: 1987-02-05
Abstract: A composite metal-plastic gear (20,120) and a method for making the gear disclosed utilize a thin-wall outer metal sleeve (22) into which involute teeth (24) are tool pressed. Thermosetting plastic (32,122) is molded in situ within the sleeve (22) between side walls (26) of the teeth (24) to provide reinforcement. Roll finishing of the sleeve (22) prior to the plastic molding finishes face and flank surfaces (34,36) on the side walls (26) of the teeth (24). Both inward and outward tool pressing of the teeth (24) can be utilized. A metallic central hub (40,124) of the gear (20,120) is positioned within the sleeve (22) prior to the plastic molding. In one gear embodiment (20) the hub (40) is engaged by an end wall (42) of the sleeve (22), while in another gear embodiment (120) the end wall (42) is spaced outwardly from the hub (124). The thermosetting plastic (22,122) adhesively bonds to the toothed sleeve (22) and hub (40,124) and includes carbon fibers that strengthen the plastic and the support provided to the sleeve teeth (24).

Title: Arrangement for the error control of a measuring device
Inventor: SCHMITT WALTER ING GRAD
IPC: G01D5/36
Filed: 1984-05-08
Granted: 1989-01-19
Abstract: A system for error monitoring in a photoelectric incremental length measuring device for the measurement of the relative position of two objects is described. The measuring device generates at least one measuring signal obtained during the scanning of a scale by means of a scanning unit. This signal is fed simultaneously to an evaluating unit and to an error monitoring unit. In the event of faulty signal parameters of the measuring signal, the error monitoring unit generates an error signal. The measuring signal is applied to an inverter and to a first AND gate. The output of the inverter is applied to a second AND gate. The two AND gates also receive the error signal as a second input. This error signal brings about an in-phase switching of the output signals of the two AND gates. The in-phase state of the signals generated by the AND gates is detected by a phase discriminator of an external evaluating unit, which generates an error signal on a respective line.

Title: Circuit breaker contact structure
IPC: H01H1/50
Filed: 1984-05-03
Granted: 1993-01-21
Abstract: After the contacts (10a,12a) close they execute overtravel to stress a spring (16) which limits overtravel and causes the contact arms (10,12) to reverse.  During return travel a stop (22) on one arm (12) engages an end (32) of a bracket (33) secured to a leaf spring (30).  The leaf spring opposes the action of the spring (16) during return travel reducing kinetic energy. When the bracket (33) engages a stop (38) both arms halted without any spurious sepn. of the contacts.  The spring (16) can be opposed by a compression spring acting on a lever engaged by the pin (18) or rotation of the arm (12) is transferred to a second pivot to modify the action of the spring (16) instead of using a second spring.

Abstract: The method removes coatings, which can be carbonised at low temperatures, from metal surfaces. The metal components are previously carbonised or pyrolised during processing. The components are brought to carbonisation temp. in an enclosed retort and without leaving the latter the carbonised coating is washed off by spraying with a heated medium, typically at carbonisation temp. This can then be passed out of the retort for cleaning and reheating and returned for spraying in a closed circuit.

Abstract: Lignin is precipitated in high yields and at high rates from a black liquor produced by pulping wood at high temperatures and pressures with an aqueous lower aliphatic alcohol solvent. The lignin is precipitated by diluting the black liquor with water and an acid to form a solution with a pH of less than 3, an alcohol content of less than 30% by volume and a temperature of less than 75 DEG C. The precipitated lignin, when subsequently dried, is in the form of a powder which requires little or no crushing to convert it into a fine uniform size suitable for use without further significant processing.

Granted: 1992-11-05
Abstract: A system for localizing a diagnostic or therapeutic agent to an internal target site. The system includes (1) a biotinylated compound, (2) an avidin-containing binding protein capable of localizing selectively at the target tissue, when administered parenterally, and (3) a clearing agent which can bind to and cross-link the binding protein, to form a protein aggregate which is readily cleared from the subject's bloodstream. In practicing the method of the invention, the binding protein is administered to the subject parenterally, and allowed to localize at the target site, typically within 1-4 days. This is followed by a chase with the clearing agent to remove circulating, but not target-localized binding protein. When the biotinylated compound is administered, binding of the compound to the localized binding protein, and rapid clearance of unbound compound by the kidneys, results in selective localization of the compound at the target site.
