Abstract: An apparatus includes a first member coupled to a second member. The first member defines a chamber containing a dry powder and includes a chamber wall that forms an outer boundary of the chamber. The second member includes a surface covering the chamber and defines an intake channel and an exit channel. The exit channel is fluidically coupled to the chamber via an exit opening. The intake channel is fluidically coupled to the chamber via an intake port. A center line of the intake channel is tangential to a portion of the chamber wall such that a portion of an inlet airflow conveyed into the chamber via the intake channel has a rotational motion. The intake port is defined at least in part by an intake ramp. The intake ramp includes a transition surface that forms an exit angle with respect to the surface of less than 105 degrees.

Abstract: A transaxle and a parking actuator assembly are provided. The parking actuator assembly may include an actuator, a rack, and the biasing member. The actuator may include a pin biased towards an extended position. The rack may be configured to carry a parking rod and may define first and second ramped recesses each configured to receive the pin. The biasing member may be coupled with the rack and may be configured to bias the parking rod towards engagement with a parking mechanism.

Abstract: Insulation tubing (66) having adjustable dimensions is disclosed. The insulation tubing has an outer tubular wall that defines a central opening for receiving the core (4) and windings (8) of a partially assembled toroidal transformer. The wall is formed by preformed sections (44, 62) of electrical insulating material (10-20). The preformed sections have overlapping surfaces that are slidably positioned relative to one another. In this way, the extent of the surfaces that overlap can be changed to alter the size of the opening such that conductive windings (8) of various sizes and configurations can be accommodated.

Abstract: A distribution transformer (58) is assembled using a core (18) having a core surface (36) including an inner circumferential surface (40) defining an open eye region (38), an outer circumferential surface (42), and end surfaces (24, 26). Wedged-shaped core supports (20, 22), secured to the end surfaces of the core, are used to support the core during conductor winding operations and to mount the finished transformer within a transformer container (66). The core supports do not extend into the open eye region and allow virtually the entire inner circumferential surface to be covered by the electrical conductors (34, 56). The layers of electrical conductors are wound on top of one another so that each successive layer of electrical conductors conforms to the core surface and any previously wound conductors. Electrical insulation (54) is provided between each conductor layer.

Abstract: Core support blockings (10, 12) used to support a toroidal transformer (2) within a transformer housing (4) includes a pie-shaped body (28) having a second end (32) secured to the transformer core (14) using an adhesive (41). The body has adhesive flow regions, typically countersunk holes (42) passing through mounting flanges (38, 40) extending laterally adjacent the second end of the body. Electrical windings (26) can be wound on first end of the mounting flanges so to help mechanically secure the body to the core. A mounting stud (46), or other mounting element, is used to secure the transformer to a support bracket (8). Together the support bracket and core support blockings are used to support the transformer within the transformer housing.
