Abstract: A fired cartridge case collector includes a base having a collection post. The collection post of the base is configured to collect and suspend a fired cartridge case without causing contact to an exterior surface of the fired cartridge case. The fired cartridge case collector also includes a protective envelope having a first end and a second end opposite the first end, wherein the first end of the protective envelope is configured to be removably secured to the base. The protective envelope is configured to prevent contact between an interior surface of the protective envelope and the exterior surface of the fired cartridge case while the protective envelope is removably secured to the base. The fired cartridge case collector permits individual collection, packaging, and non-contact storage of fired gun cartridge cases thereby preserving any DNA or other evidence that may be present.

Abstract: A fastener forming apparatus produces a fastener of metal having a rod-to-plate connection often found in such applications as an automotive door latch striker. The fastener is formed and assembled in a single operation and with only a rod and a stamped plate for parts. The forming apparatus has a die structure for securing the rod, a base for vertically aligning the rod, a compression pedestal for vertically aligning the plate and a suspended stamping structure. The stamping structure moves from a pre-staged position for loading of the rod and plate to the die structure, to an intermediate position wherein a head is substantially formed unitarily at the end portion of the rod on one side of the plate, and formation of a unitary protrusion is initiated from the same end portion but on an opposite side of the plate.

Abstract: A headed fastener clip having a threaded shank with a T-head embedment molded in a hex nut head for rotatably threading the clip into a support. A trim piece attachment post protrudes oppositely from the shank. A pair of spring arms are cantilevered from the post outer free end and diverge dependently therefrom to free ends spaced closely above the nut head. A catch portion adjacent each arm free end dimensioned to overlaps in use mutually opposed marginal edges of a fastener-receiving opening in the trim piece. The nut head has platforms on the head that underlie and support the opening marginal edge when the trim piece is installed on the clip. The fastener clip is first threaded into the support, the trim piece fastener opening registered with clip head and then the trim piece is pushed toward the support.

Abstract: A flexible backplane assembly is provided wherein removable backplane modules are mounted in a platform in a manner such that the backplane modules may be removed and replaced to accommodate different types of circuit modules. Coacting guides are provided on the platform and the backplane modules to define a travel path for module insertion and removal which prevents contact with adjacent circuit and backplane modules and maneuvers around platform structural members. Connectors at the rear of each backplane module for mating withy circuit module connectors may be electrically connected to I/O boards at the front of the module to permit wiring of the backplane modules from the front of the platform.

Abstract: A fastener assembly with a recess in a part in which a nut is received with resilient fingers engaging with an interference fit the periphery of the recess to retain the nut therein. A fastener with a threaded stud is engaged and retained by a threaded hole through the nut. Preferably, the nut is a relatively thin and generally flat plate with the threaded hole formed by displacing a portion of the plate around the periphery of the hole.

Abstract: A clip for retaining a headed fastener in a hole in a plate. The clip is a U-shaped strip of flexible, resilient material with legs for engaging opposite sides of the plate. One leg has a clearance hole for the head of the pin and the other leg has a clearance slot for the shank of the pin. The leg with the head clearance has a tab which overlies the head of the pin to retain the pin in the hole.

Abstract: Anionic Emulsions of asphalt, bitumen, or tar which may optionally contain a latex of a rubbery polymer may be set using a destablizing system comprising either an alkali silicofluoride in the presence of a sulfamate or a mixture of an amine in the presence of a divalent metal ion. The setting time for such emulsions can be reduced to less than half an hour.

Abstract: A fastener with a metal stud removably receivable in a plastic carrier member. A shank of the stud is inserted through a hole in the carrier member and an enlargement on the shank limits the extent to which the shank can be pushed through the hole. The stud is retained in the carrier member by entrapment of a portion of the carrier member surrounding the hole between the enlargement and a ring on the shank which has an interference fit with the hole. To facilitate inserting the ring into and removing it from the hole, the sides of the ring are tapered. The carrier member can be journaled on the shank to rotate freely with respect to the stud. If it is desired to prevent this rotation, the enlargement can have a non-circular configuration and be received in a mating non-circular recess in the carrier member.

Abstract: The viscosity of an asphalt emulsion may be controlled by incorporating up to about 1 percent by weight of a modified starch containing not more than 27 percent amylose and the balance substantially amylopectin.
