A parallel eccentric electro-mechanical actuator provides motive power and includes an electric prime mover that drives the reducer's pinion gear. This pinion drives minimum three star gears with stationary shaft bearings. Each shaft contains an eccentric which are completely in parallel with each other. These eccentrics can be thought of as parallel/in-phase driven crankshafts. Each eccentric drives the parallel eccentric (PE) gear through a bearing. The PE gear exhibits a circular motion (without rotation) which in itself is unbalanced. The crankshafts have another eccentric which create an opposite inertia force to balance that of the PE gear. The PE gear contains an external toothed gear on its periphery. It meshes with the internal teeth of the output ring gear. The relative motion between the PE gear and the ring gear is that the PE gear rolls inside the ring gear. This relative motion is called hypo-cycloidal motion.

Methods are disclosed for handling cylindrical tubulars in a process that, in preferred embodiments, also performs cleaning, inspection and other operations on the tubular. The tubular is held stationary while it is rotated. During rotation of the tubular, internal and external cleaning systems, and data acquisition systems, pass up and down the length of the rotating tubular. In preferred embodiments, a first tubular is loaded onto the handling machine, whereupon it is indexed and then rotated. Cleaning, inspection and other operations may be performed during rotation. Once operations are complete, the handling system ejects the first tubular while queuing up a second tubular to be loaded.

A rear end gear box cover for a racing car is formed with a fixed base plate and a removable top plate. The base plate is fixed to the rear end housing by multiple fasteners while the top plate is removable from the base plate. The top plate includes a pair of opposing cam members carrying connector pins for engagement with receiver mounts formed on the base plate. A cam driver on the top plate has a central connector member that when rotated drives a pair of opposing cam pins carried in a slotted opening on the cam members outwardly to force the connector pins into openings in the receiver mounts and secure the top plate to the base plate. A detent mechanism in each of the slotted openings retains the cam members in a locked position. A quarter turn of the connector member retracts the connector pins.

An Auxiliary Power Unit (“APU”) for an aircraft with reduced weight, but which at the same time meets all fire-related airworthiness standards. The APU comprises a metallic housing having mounts for attaching the housing to an external structure. The APU further comprises at least one temperature sensor suitable for detecting temperature under fire conditions. The temperature sensor is coupled with the mounts for sensing temperature at the housing.

A differential gear case is provided that includes a container housing of a differential gear, the container housing having on an outer surface thereof an annular flange that extends around an axis of rotation of the container housing, and one of two areas of the container housing that are separated by the annular flange being formed with an opening that is communicated with a containing space formed in the container housing. The area of the container housing that is formed with the opening is provided with a fixing portion used for fixing the differential gear case. The fixing portion includes two flat surfaces that are in parallel with a plane surface containing the axis of rotation of the container housing and arranged around the axis of rotation keeping a space therebetween.

A transaxle includes an input shaft, a brake, an output shaft, a mechanical transmission, a transaxle casing, and a spacing system. The brake is provided on the input shaft. The brake includes layered friction elements. The transmission transmits power from the input shaft to the output shaft. The transaxle casing includes a housing defining both a brake chamber and a transmission chamber. The brake chamber incorporates the brake. The transmission chamber incorporates the transmission. The spacing system is configured so as to provide the transaxle casing with a partition wall between the brake chamber and the transmission chamber, so as to hold a bearing in the partition wall to journal the input shaft, and so as to provide a spacer for the layered friction elements of the brake, the spacer defining a space in the axial direction of the input shaft in correspondence to a thickness of the layered friction elements in the axial direction of the input shaft.

A holding structure of an intervening member is provided for preventing the dropping-out of a wobbling-prevention member at an assembly time, and to extend an applicable range of rigidity of the intervening member to a low-side range. The holding structure of the intervening member includes a baffle plate intervened between a torque converter housing wall and an intervening member, and a wobbling-prevention member interposed between the baffle plate and the torque converter housing wall in a compressed state. A bottom portion of a concave portion is clamped between a head portion and a bulging portion of the wobbling-prevention member. Also, an inside of the head portion is hollow, so when the head portion is crushed and deformed, the air inside the head portion is discharged to the outside through an annular gap to reduce a compressive load relative to the baffle plate.

A method for calibrating an automated window covering includes electromechanically actuating a window covering and measuring electrical current required to actuate the window covering. The method further measures movement of the window covering, where such movement includes one or more of a change in position and velocity of the window covering. The method estimates a size (e.g., height, width, area, etc.) of the window covering and/or an amount of force required to actuate the window covering based on the measured electrical current and movement. A corresponding apparatus is also disclosed herein.
