摘要： A spacer grid for a nuclear fuel element comprises a plurality of cojointed cylindrical ferrules adapted to receive a nuclear fuel pin. Each ferrule has a pair of circumferentially spaced rigid stop members extending inside the ferrule and a spring locating member attached to the ferrule and also extending from the ferrule wall inwardly thereof at such a circumferential spacing relative to the rigid stop members that the line of action of the spring locating member passes in opposition to and between the rigid stop members which lie in the same diametric plane. At least some of the cylindrical ferrules have one rim shaped to promote turbulence in fluid flowing through the grid.

摘要： An alternating current electric motor has a stator comprising an inductive winding in association with capacitance to ensure that the winding has the characteristics of a transmission line. The rotor of the motor may be of the induction, hysteresis or reluctance type. In one form, the winding of the stator is toroidal, such as gramme ring type, with shunt capacitors at fixed intervals along its length. In an alternative form, a linear motor has a solenoid type stator winding with shunt capacitors at fixed intervals. The invention enables speed to be closely defined without being essentially related to supply frequency.
摘要翻译：交流电动机具有与电容相关联的电感性绕组的定子，以确保绕组具有传输线的特性。电动机的转子可能具有感应，迟滞或磁阻型。在一种形式中，定子的绕组是环形的，例如克仑环型，其沿着其长度具有固定间隔的并联电容器。在另一种形式中，线性电动机具有固定间隔的并联电容器的螺线管式定子绕组。本发明使速度能够被紧密地定义，而不必基本上与供应频率相关。

摘要： Apparatus for use in taking measurements in downwardly extending channels resides in a probe on which is fixed a track and a carriage captive on the track carries measuring transducers with electrical outputs. The probe is suspended in the channel and moved upwards, stepwise. At each position the carriage is traversed along the track and the response of the transducers which may be electrical signals indicative of channel profile dimensions are carried by an electrical conductor to indicators situated remote from the probe.

摘要： A shear machine for irradiated nuclear fuel elements has a replaceable shear assembly (1) comprising a fuel element support block (4), a shear blade support (16) and a clamp assembly (15) which hold the fuel element to be sheared in contact with the support block. A first clamp member (7) contacts the fuel element remote from the shear blade and a second clamp member (8) contacts the fuel element adjacent the shear blade and is advanced towards the support block during shearing to compensate for any compression of the fuel element caused by the shear blade (2).
