Abstract: Abstract of the Disclosure An improved cartridge loader of the type having a generally star shaped latch rotatably carried within a casing, the casing defining a plu-rality of cartridge bores positioned circumferentially around the latch. Upon rotation of the latch, the latch and each cartridge bore cooperate by alternately capturing and releasing a cartridge's flange within that bore for loading and unloading cartridges therefrom.  A first novel feature of this improved loader is a semi-automatic rotation device for the star shaped latch, which device induces rotation of the latch from the capturing position to the releasing position in response to an external force directed axially against the loader's knob when the casing is restrained against rotational motion, e.g., when the cartridges in the casing are disposed in an unload attitude relative to a revolver cylinder, and which will not induce rotation of the latch unless the casing is so restrained for preventing accidental release of stored cartridges if the loader is dropped or otherwise subjected to an undesirable external force on the loader's knob.  The semi-automatic rotation device is also manually operable to set the latch from the releasing position to the capturing position, and to return the latch from the capturing position to the releasing position, simply by manually rotating the loader's knob.  In a preferred form of the semi-automatic rotation device, the knob is connected to a centerpost through a spring loaded cam structure, the star shaped latch being immobily fixed to the centerpost.  A second novel feature of this improved cartridge loader incorporates a resilient but stationary bore closure member that, preferably, defines a circular contact locus radially outward of the cartridge bores' circular center axes locus.  The latch and bore closure member cooperate to minimize jiggling of cartridges stored within the casings' bores for reducing undesirable noise, to allow nominal unopposed movement of the cartridges' nose ends relative to the casing for aiding initial cartridge insertion into a revolver's cylinder when loading the cylinder, and, when the casing is dropped, to cushion any shock transmitted to the cartridges' flanges and to protect the cartridges' firing pins.  In a preferred form, the cover member is defined by a one-piece multi-fingered washer type structure coaxially located, and fixed in position, relative to the casing, the resilient fingers overlying the casing's bores at the car-tridge flange end thereof.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a system for determining which of a plurality of molds produced a particular con-tainer.  A concentric ring code is molded into the bottom of each container as it is produced.  The containers are then passed by a reading station, where light whose intensity is proportional to the angle of incidence is projected onto the bottom of the container.  Readings are taken of the variation of intensity of light reflected to a particular point in order to determine the position of rings on the con-tainer.  Suitable electronics then decode the ring position to determine the container code, thus allowing identification of the mold which produced each container.

Abstract: SAFETY PRESSURE REDUCING REGULATOR     ABSTRACT OF THE DISCLOSURE     A safety pressure reducing regulator for use in systems operable by pressurized gas incorporates multiple safety features which preclude excessive pressure buildup in the system and provide protection against catastrophic failures.  The regulator includes primary and secondary regulator stages through which pressurized gas from a gas pressure source is supplied to a pressure control chamber which provides the operating pressure for the system.  The primary regulator stage is designed to reduce the inlet gas pressure to an intermediate level.          The secondary regulator stage is designed to automatically regulate the supply of the pressurized gas at the inter-mediate pressure to the pressure control chamber to maintain a desired operating pressure therein.  A flexible diaphragm is normally disposed across the pressure control chamber which is adapted to function as a check valve to control communication between the secondary regulator stage and the pressure control chamber.  A clamping piston provided with a central passage normally clamps the flexi-ble diaphragm in place across the pressure control chamber.          In the event of excess pressure buildup in the pressure control chamber, the piston unclamps the diaphragm which collapses into its central passage to permit the pres-surized gas to escape through exhaust vents.
