Abstract:
An encapsulated solenoid assembly (10) including an electronic actuator (12) and an elongate metallic armor tube (14) for receiving an electrical conductor (16) therethrough which is electrically connected to the electronic actuator (12). The electronic actuator (12) and an end portion (14a) of the armor tube (14) are encapsulated within an outer casing of encapsulated material (18) to integrally couple the armor tube (14) with the electronic actuator (12) without the use of additional connection components or complex attachment arrangements. In one embodiment, the armor tube (14) is corrugated to facilitate bending and to aid in maintaining engagement with the encapsulation material (18). In another embodiment, the electronic actuator (12) includes a magnetic plunger (42) that is displaceable along an actuation axis (L1), with the armor tube (14) extending along a longitudinal axis (L2) laterally offset from the actuation axis (L1). In a further embodiment, the electrical conductor (16) extends alongside a substantial length of the electronic actuator (12) so as to become embedded within the outer shell of encapsulation material (18).

Abstract:
Permanent magnet assemblies and hybrid magnetic apparatus are disclosed for use in medical applications, particularly permanent magnet assemblies for use in interventional Magnetic Resonance Imaging (iMRI) and/or Magnetic Resonance Therapy (MRT) to produce a volume of substantially uniform magnetic field in a restricted part of the patient's body in a region either adjacent to the surface of one permanent magnet assembly or between a set of a first and second permanent magnet assemblies, leaving open access to the patient's body. The assemblies consist of a plurality of annular concentric magnets spaced-apart along their axis of symmetry. A method for constructing such annular permanent magnetic assemblies is disclosed, using equi-angular segments permanently magnetized. The hybrid magnetic apparatus includes an electromagnet flux generator (150, 152) for generating a first magnetic field in the volume, and permanent magnet assemblies (160, 162) for generating a second magnetic field superimposed on the first magnetic field for providing a substantially homogenous magnetic field having improved magnitude within the volume.
Abstract:
A novel solenoid assembly (10) is shown to include a solenoid (14) having an armature (20) and a delay member (40). The delay member (40) delays movement of the armature (20) from a first position to a second position until some desired condition occurs, for example, until a desired period of time has passed, until the solenoid (14) is capable of generating a desired amount of force or until the current applied to the solenoid (14) reaches a desired level. In a preferred embodiment, the delay member (40) is a spring (34) positioned to bias the armature (20) against movement until the desired condition has occurred. In such an embodiment, the spring (34) may be positioned to exert force against a shoulder formed on the armature (20). It is also preferred for the solenoid assembly (10) to include a spacer (24), positioned between the solenoid (14) and the mechanism being controlled by the solenoid (14). The spacer (24) serves to space the armature (20) from the mechanism when the armature (20) is in the first position. In a further embodiment, the solenoid assembly (10) further includes an extension member (26) attached to the arm (22).
Abstract:
An electromagnet assembly (14) magnetically orients a thin magnetic film (98) deposited onto a surface of a substrate. The magnetic orientation can take place in a low-pressure processing environment (16) such as during the deposition of the thin magnetic film or during a subsequent operation such as annealing. The electromagnet assembly includes a plate-shaped core (40) located adjacent to the substrate and two or more electromagnetic coils (42, 44) that are wrapped in different directions around the core. Electrical currents conveyed through the electromagnetic coils are controlled (46, 48) for orientating a substantially uniaxial magnetic field throughout a range of angular positions in a plane of the substrate surface.
Abstract:
The present invention is a two or more-piece cascading armature for use in a solenoid. The cascading armature comprises a core (174) of conductive material slidably disposed within at least one conductive sleeve (176), which, in turn, is disposed in the solenoid housing. The core and sleeve are operably linked. In various embodiments, the cascading armature may contain multiple conductive sleeves in varying sizes and proportions to the core. When the cascading armature is installed in the conductive housing, both the sleeve rim (179) and the core face (172) are presented to the pole member face across the working air gap. In the deactivated position the working air gap is different for the core and the sleeve because the rim of the sleeve extends beyond the core and is accordingly closer to the pole member face than the core.
