Abstract: The present invention is directed toward an improved foam mattress. In one embodiment, the mattress has a base layer coupled to rectangular side sections each having a top surface. The top surfaces of the side sections extend above the top surface of the base layer and define a periphery of a space. The base layer and side sections are made of a material having a first resiliency. A central core layer is configured to fit entirely within the space defined by the side sections and is made of a material having a second resiliency, where the second resiliency is lower than said first resiliency. A top layer rests on the top surface of the central core layer and the top surface of the side sections. The top layer is made of a material of having a resiliency equal to or less than the second resiliency.

Abstract: A lead frame assembly comprises a stamped and formed lead frame having spaced pairs of electrical terminals and other contact sections. Severable sections initially interconnect potential electrical circuit sections of the lead frame separating the lead frame into separate metal members defining discrete electrical circuits if severed. A dielectric covering is molded over the lead frame exposing the pairs of terminals and other contact sections for termination or electrical engagement. Openings are formed in the housing exposing the severable sections of the lead frame for severing, to be selectively severed creating separate electrical circuit sections, or to be retained unsevered, as desired. After the molding of the covering over the lead frame, the article thus fabricated can be customized by selective severing and connecting of components as desired.

Abstract: A connector assembly for an anti-skid hydraulic braking system comprises a bulkhead connector extending through an aperture in a sidewall of the brake fluid reservoir, a connector harness mounted along the inside of the reservoir sidewalls extending from the bulkhead connector to three solenoid assemblies mounted on the reservoir floor, and a solenoid connector on each solenoid assembly in engagement with the connector harness. The solenoids extend through floor apertures into the master cylinder to respective hydraulic lines extending to brake cylinders in the wheels, one of the solenoids handling both rear wheels. The bulkhead connector mates with a connector outside the reservoir which is terminated to a wire harness connected to the on-board microprocessor to relay current to the solenoids when data from individual wheel speed sensors is processed to determine that a particular wheel is about to skid.

Abstract: A floating first electrical connector 11 (such as a receptacle) has a plurality of contacts adapted to mate with complementary contacts carried by a second electrical connector 21 (such as a plug). The receptacle 11 has a limited floating movement within the plane of an opening 12 in a panel 13 (of a power supply or other electrical apparatus) and a retaining clip 17 is snapped over the receptacle 11 (from externally of the power supply) to releasably secure the receptacle 11 on the panel 13, yet accommodate the limited floating movement of the receptacle 11. The receptacle 11 is retained by the retaining clip 17, externally of the power supply, but the receptacle 11 is only accessibly internally of the power supply. The arrangement permits a smooth engagement between the contacts on the plug 21 and receptacle 11, respectively, either by an axial sliding movement or by a relative angular movement therebetween.

Abstract: A spring for a switch actuating assembly is of generally E-shape or sinuous configuration wherein inwardly-curved free ends of outer sections are adapted to engage the legs of a central U-shape section when the spring member is compressed, thereby limiting the movement of the outer sections and increasing the spring characteristics of the spring member. The spring can be disposed in a slide member in a housing and be movable from one selected position to another so that the spring moves a movable contact member from an electrically connected condition to a disconnected condition.

Abstract: A motor brush assembly comprises a stamped and formed lead frame including electrical terminals at spaced locations and a dielectric housing member secured onto the lead frame with the electrical terminals being exposed and accessible for electrical termination to electrical power wires and lead wires of capacitors and inductors. Cavities are located in the housing member in which the inductors are disposed.

A spring-biased movable contact assembly is disposed between the stationary contact assemblies and includes cantilevered arcuate contact sections springably engaging respective aligned contact segments. The exposed contact sections have parallel projections and the dielectric sections have a projection along which the arcuate contact sections move, one of the parallel projections being longer so that, when the arcuate contact sections move from the contact sections onto the dielectric sections or vice versa, the arcuate contact sections engage the longer projection last or first so that an electric arc, if it occurs, will occur therebetween rather than between the short projections and the arcuate contact sections.
