Abstract: An electrical machine is disclosed. The electrical machine has a first part and a second part, the first part moveable relative to the second part. One of the first part and the second part has a plurality of cores for current-carrying windings. Each core is of soft magnetic composite material (SMC) and is shaped to be no wider at its ends than along its length.

Abstract: A dispensing apparatus has a plunger reciprocable in a barrel, the plunger head defining with the barrel a variable volume pump chamber, a way-one fluid inlet valve for allowing fluid to flow into the chamber on increase of the chamber volume and a fluid outlet valve allowing fluid to flow out of the chamber when the volume decreases, a spring biasing the plunger toward a first position and a plunger actuator for actuating the plunger toward a second position, and a plunger damper for decelerating the plunger when moving toward its first position but before it reaches the end of its first position.

Abstract: A consumable assembly consituting the source of metal for welding by the electroslag process, comprising a stainless steel guide sleeve, a tube of copper inside the guide sleeve, and a weld wire inside the copper tube.

Abstract: Sections of cast manganese steel, or manganese steel to be interfaced to another steel, are joined by electroslag welding. Metallurgical limitations, operating parameters and physical attributes of the guide tube are imposed to retard embrittlement of the base metal and weld metal as well, to prevent tearing, to assure satisfactory ductility, and to preserve the integrity of the austenitic manganese steel in the weld metal.
