Abstract: An apparatus is described for burn-in and/or functional testing of microelectronic circuits of unsingulated wafers. A large number of power, ground, and signal connections can be made to a large number of contacts on a wafer. The apparatus has a cartridge that allows for fanning-in of electric paths. A distribution board has a plurality of interfaces that are strategically positioned to provide a dense configuration. The interfaces are connected through flexible attachments to an array of first connector modules. Each one of the first connector modules can be independently connected to a respective one of a plurality of second connector modules, thereby reducing stresses on a frame of the apparatus. Further features include for example a piston that allows for tight control of forces exerted by terminals onto contacts of a wafer.

Abstract: A plastic film bag includes a reclosable closure which is opened and closed by a slider. The bag includes a tamper evident sheet closing off the bag mouth. Alternatively the tamper evident means consists of a hood which encloses the slider and reclosable closure.

Abstract: A slider zipper reclosable fastener wherein the zipper includes fastener strips and closure elements on the fastener strips which are extruded integrally. The closure elements are arranged at particular angles by extrusion opening angles in order to increase burst strength. Ridges on the fastener strips and shoulders on the slider hold the slider on the zipper.

Abstract: In a thermoplastic bag having a reclosable fastener extending along the mouth of the bag and a slider straddling the fastener for opening and closing the fastener, the fastener including two opposing interlocking profiles along the side walls of the bag, the slider adapted to maintain straddling relation with the fastener, an improved endstop means proximate to at least one end of the reclosable fastener, the endstop means being formed from the material of the profiles and rising vertically from the fastener to a height adequate to engage the slider and prevent movement of the slider past the end of the bag. A rail extends along the length of at least one of the profiles on the outside thereof, the rail extending to a point sufficient to permit the slider to cooperate with the rail to maintain straddling relation with the fastener when the slider reaches the endstop. Docking means and methods of making endstop means and docking means are also disclosed.

Abstract: A security bag having attached thereto an auxiliary bag with a reclosable zipper. The security bag is sealable by a flap having hot melt adhesive thereon. Tamper evidence is provided by a permanent color change of a colored marking adjacent the flap. The color change results from the application of extreme cold temperature to the flap.

Abstract: An improved fitting is disclosed for receiving and sealing an aerosol cannister. This fitting employs an annular sealing ring on the fitting to seal against one or more peripheral surfaces of the recess defined by the valve assembly of the aerosol cannister.

Abstract: An automatic dispenser for injecting starting fluid into an internal combustion engine is disclosed. This dispenser includes a valve actuator which is adapted to receive a valved cannister containing a pressurized starting fluid and to pass starting fluid from the cannister through a conduit to an injector positioned in an air intake passage of the engine. The valve actuator is coupled to the starting system of the engine so that the cannister valve is continuously injected into the engine during operation of the engine's starter motor. In this way a continuous flow of starting fluid is automatically dispensed during engine cranking. The valve actuator is also provided with a reservoir which temporarily stores a predetermined volume of starting fluid while fluid is flowing through the actuator, and then supplies this fluid to the injector after the cranking has stopped, thereby providing starting fluid to the engine during the period immediately following termination of cranking.

Abstract: An improved cannister mounting bracket is disclosed which is adapted for use with a valve assembly. The bracket may be readily adjusted to accommodate cannisters of two differing sizes and to provide protection for the valve assembly when no cannister is mounted in place. Adjustment is made in large part through a pair of link members and a pivotable frame member which can be rotated in order to alter the configuration of the bracket.

Abstract: An improved starting fluid injection apparatus for an internal combustion engine includes a valved container of starting fluid, a valve actuator, an injector assembly, and a conduit interconnecting the actuator and the injector assembly. According to a first feature of the invention, a flow metering orifice is provided in either the actuator, or the conduit at a point spaced from the injector assembly, or the injector assembly. This orifice relieves constraints related to fluid metering from the injector orifice, and permits the use of a greater number of larger injector orifices than would otherwise be possible. Multiple flow metering orifices can be used upstream of the injector orifices. Additionally, in some applications it is possible to dispense with injector orifices entirely.
