Abstract: Disposed in a preassigned position the driving and braking mechanism comprises a carrier arm (46) medially pivoted on a fixed support for oscillation about an axis parallel to reels.  each carrier arm has a driving roll (50) and a brake (52).  As the carrier arm (46) is oscillated by the fluid actuated cylinder, the driving roll and the brake roll are altermately movable into and out of frictional engagement with the periphery of a flange (36). The rotation of a reel or reels can be arrested upon completion of the winding by swinging the carrier arm (46) or arms in the opposite direction; the brake moves into frictional engagement with the reel.

Title: Tools for disassembling universal joints
Inventor: LOSTRA JOHN M
IPC: B23P19/02
Filed: 1986-02-18
Granted: 1994-08-08
Abstract: Tools for the disassembly of a universal joint comprise two embodiments, a push-type tool and a pull-type tool. With respect to the push-type tool (Fig. 6), a cylinder/piston combination (18, 20) is mounted on a pushing or support assembly (80), and the cylinder/piston combination (18, 20) is operated to force the piston (20) against the support assembly (80), which in turn exerts a pushing force on the cross (intersection point of the yoke members) of the universal joint. At the same time, the cylinder (18), which is connected to the near end of a yoke member of the universal joint, exerts a pulling force on the universal joint, thereby forcing a journal bearing out of the yoke member. In the pull-type tool (Fig. 3), a cylinder/piston combination (18, 20) interposed between a pulling assembly (12, 14, 16) and a pushing assembly (28, 30) operates to cause the exertion of pulling and pushing forces on the universal joint, so that a journal bearing is forced out of the universal joint.

Abstract: 원자로용 연료 공급기 지지를 위한 브리지 배치는 외팔보로서 브리지를 지지하는 하나의 주탑을 가진다. 주탑에 인접한 균형추탑은 무게가 브리지 무게에 연료 공급기를 더한 것과 동일한 균형추를 운반한다. 수직 이동을 위해 최소 마찰을 제공하도록 롤러를 사용하여, 브리지가 주탑에 설치되고, 균형추가 균형추탑에 설치된다. 양탑에서 수직 볼 나사는 각각 브리지의 균형추상의 너트에 결합된다. 브리지가 상승하고 균형추가 하강하고 또는 반대가 되도록 기어가 두볼 나사와 함께 결합된다. 굽힘력은 브리지를 따라서 연료 공급기의 위치를 변화시키지만 실제 무게는 변하지 않는다. 그러므로 주탑에서의 나사상의 무게는 한쌍의 지지탑중의 하나의 탑에서 변화되는 것같이 변화되지 않는다. 균형추로 인해 브리지를 상승시키는데 훨씬 적은 동력이 필요하다.

Abstract: A three-phase stator current is resolved by A/D conversion into d- and g-axis components. Pulses corresponing to revolution of a rotor are counted and four proportional-integral controller are used in approximate computation of deviations of rotor flux and resistance from estimates. The variations of temperature and environmental influences are taken into account in adjustments to the three-phase current for compensation of the resistance of the rotor. Precision of control is not impaired by variation of rotor resistance.
