Title: Discrete position estimator for a switched reluctance machine using a flux-current map comparator
Inventor: LYONS JAMES P
IPC: H02P6/18
Filed: 1992-08-13
Abstract: RD-21,053 DISCRETE POSITION ESTIMATOR FOR A SWITCHED RELUCTANCE MACHINE USING A FLUX-CURRENT MAP COMPARATOR                             Abstract A rotor position estimator for a switched reluctance motor (SRM) employs a flux-current map to determine whether the actual rotor angle is closer to, or farther from, axial alignment of stator and rotor poles than a reference angle .theta.r. The flux-current map is a plot of reference flux ?r as a function of current for the reference angle .theta.r. If a flux linkage estimate ?i is greater than the reference flux ?r, then the actual rotor angle is closer to alignment than the reference angle .theta.r, and the flux-map comparator output is a logic level one.  If the flux linkage estimate ?i is lower than the reference flux .theta.r, then the actual rotor angle is farther from alignment than the reference angle .theta.r, and the flux-map comparator output is a logic level zero.  When the result of the flux comparison causes the flux-current map comparator to change state, the actual rotor angle is equal to the reference angle .theta.r, with the result that phase currents can be successfully commutated relative to this rotor position.  The flux-current map can be implemented using either single-phase or multi-phase SRM flux-current characteristics.

Title: Method and apparatus for alignment of several machine units arranged in series
Inventor: GUARALDI GLENN A
IPC: G01B5/25
Filed: 1992-09-22
Abstract: A method for-aligning at least one machine unit (36) on a base (42) comprises the steps of installing alignment markers (28) on the parts (12, 14) of a machine unit (36) to be aligned, and correcting the locations of the alignment markers (28) to effect a correction in the locations of the parts (12, 14) on which they are installed.  The alignment markers (28) are installed in positions which have precise relationships to the positions of function specific openings (20) in the parts (12, 14) which are preferably formed in metal cutting machining.  A correction in the locations of the alignment markers (28) thus effects a correction in the locations of the function specific openings (20).  The alignment markers (28) enable an alignment of parallel parts (12, 14) of a single machine unit (36) as well as alignment of several machine units (36, 38, 40) arranged one after the other in series.

Title: Reclining chair
Inventor: VOELKLE ROLF
IPC: A47C3/026
Filed: 1992-10-01
Abstract: ABSTRACT                   RECLINING CHAIR            In a reclining chair a seat carrier and a reclining backrest carrier are movably interconnected to perform synchronized shifting movements relative to the frame of the chair. The bottom end portion of the backrest carrier extends under the seat carrier. Connecting means connect the seat carrier and the backrest carrier to each other and cause them to move at the same time. When the body of a person sitting on the seat carrier initiates a shifting movement of the backrest carrier from a steep position to a reclined position, the seat carrier will be moved forwardly at the same time and at least its rear portion will be lowered. Because the backrest carrier and the seat carrier are connected to the connecting means at spaced apart points, any movement of one of said carriers will be transmitted to the connecting means and by the latter to the other carrier. In spite of their connection by the connecting means the two carriers are guided on the frame along paths which are independent of each other. During the reclining movement the backrest carrier is lowered to an at least slightly larger extent than the seat carrier adjacent to the latter. As a result, an inexpensive reclining chair is provided, which can conveniently be moved to a reclined position for a comfortable rest.

Abstract: A friction clutch wherein a pressure plate is axially movably but non-rotatably coupled to a cover and is biased by a diaphragm spring to urge the friction linings of a clutch disc against a flywheel which is driven by the engine of a motor vehicle. The diaphragm spring is tiltable relative to a set which is carried by the cover, and a second spring is provided to bias a portion of the seat against the diaphragm spring. The latter can be moved axially of the flywheel to compensate for wear upon the friction linings, particularly when the flywheel is idle or is driven at a relatively low speed. The device which compensates for wear upon the friction linings is installed between the diaphragm spring and the cover, and its purpose is to ensure that the bias of the diaphragm spring upon the pressure plate in engaged condition of the friction clutch remains at least nearly constant regardless of the extent of wear upon the friction linings and certain other parts including the diaphragm spring, the pressure plate, springs which form part of the clutch disc to urge two sets of friction linings axially and away from each other against the flywheel and the pressure plate, respectively, and leaf springs which connect the pressure plate to the cover.

Title: Method and apparatus for inspecting a printed circuit board (shutter system)
Inventor: WASSERMAN HAROLD
IPC: G01B11/245
Filed: 1993-02-19
Abstract: A method and apparatus for inspecting articles such as printed circuit boards doubles the transport rate for the article under inspection, and modifies the manner in which acquired video images are processed to account for this change in rate.      Primarily, this involves two modifications to existing video processing systems including a change in synchronization for obtaining the frames which are to be processed, and a selective exposure (i.e., shuttering) of the video cameras to the images which are to be acquired in order to avoid the acquisition of plural images in a single frame. Once acquired, the video images are stored and processed making use of techniques which substantially correspond to those previously employed by existing inspection devices of this general type.

Abstract: Connectors for electrical components include a support base having an edge which defines an open space, and an electrically insulated socket member connected to the support base within the defined open space for holding and establishing electrical connection with the electrical component. The socket member includes opposed pair of side walls, an upper wall and a lower wall which collectively establish an open ended interior space. At least one clamp connector is disposed in a rearward end of the interior space and is coupled to the socket member for receiving a terminal portion of an electrical component inserted into forward end of the interior space so as to connect the electrical component electrically to an external circuit. Opposed pairs of separated upper and lower locking tabs are formed on either the side walls of said socket member or the support base, and project outwardly therefrom. These upper and lower locking tabs serve to connect the socket memberto the support base and positionally restrain the socket member within the defied space. Preferably, the edge of the support base defines an enlarged forward space in which the electrical component is disposed, and a rearward space in which the socket member is disposed. In this regard, the support base will most preferably include inwardly projecting retaining ears disposed at a juncture between the forward and rearward spaces.
