Abstract: The subject invention is a process for improving the performance capacity of chaplets or spacer supports as used in metal casting as supports adjacent the mold cavity, said process comprising the steps of immersing the chaplet into a water-based solution of borax and thereupon employing the chaplet in the molding process with said solution covering the chaplet.

Abstract: A pressure measuring device for enclosed bottles, such device being adapted to measure the internal pressure inside an enclosed bottle. The device comprises a pressure measuring gauge integrally interconnected with a bottle cap such that the pressure gauge stem is integrally inserted through the cap to extend into open communication with the internal chamber of the bottle.

Abstract: The subject invention is a device for vertically connecting members relative to one another in order to prevent rotational movement relative to one another, and wherein the invention resides in an adapter plate structured to be sandwiched intermediate the upper surface of the lower connected member and the lower surface of the upper connected member. The adapter member is generally comprised of a rectangularly shaped plate member having on opposite sides thereof reverse flange projections, one such projection structured to ride down along the vertical wall of the lower connected member; with the opposite flange structured to ride vertically up the vertical wall of the upper connected member, or vice versa. An opening is structured in the plate to receive a portion of a bolt member, which may be used to interconnect the two members.

Abstract: The subject invention is a multiple access mailbox and parcel receptacle, which comprises, in general, a longitudinally extending housing with a correspondingly internally disposed hollow chamber. Said hollow chamber conforms, in general, to the external shape of the mailbox, and there is dual entry access to this hollow chamber. First, there is a hinged door for entrance from what is considered to be front of the box, with a second access door on either the sides, back, or front of said mailbox. A spring-loaded hinge member is integrally interconnected with said second door whereby said second access door automatically swings shut after opening, and there is a one-way locking device by which arrangement such second door cannot be pushed open from the inside.

Abstract: The subject invention is a device for facilitating the interconnection of support rod members relative to one another in order to provide a unified and integrated frame member for supporting a boat covering, or similar device. The subject invention comprises mainly a bifurcated structure specifically supporting two opposing hollow cylindrical members aligned along a common central axis, with each adapted to hold the end of a support rod in the frame. An opening is provided through the bottom surface of the bifurcated member to receive a portion of a bolt member, which may be used to interconnect the subject device to another such similar device in a mutually perpendicular fashion. As thusly interconnected, the two connected devices provide a support intersection for interconnected rod members in the framework system.

Abstract: The subject invention is a lawn mower blade hub member adapted for interconnecting a plurality of flexible blades, all affixed and disposed in a radial fashion from the centrally disposed hub member, which hub member is then mounted for concentric rotation on the lawn mower engine drive shaft; and wherein each such blade mounted to the hub member is comprised of a flexible, non-rigid, material. The hub member is a circular, plate-like member which has a plurality of insert openings which are adapted to receive and securely hold the radially inner ends of the respective flexible blade members. Disposed laterally adjacent to and just radially outwardly of the respective insert openings are vertically extending bosses, which bosses are disposed between the respective insert openings, thereby forming between adjacent bosses a channel area to securely hold a portion of the radially inner end of the flexible blade member in a radially outwardly rigid position.

Abstract: A multipurpose electronic assembly for a headphone assembly used in connection with a stereophonic system, such system comprising detection and signal means to ascertain noises extraneous to the stereophonic output system. Such assembly comprises a pick-up microphone in one or more speaker assembly for such ambient sound pick-up. The pick-up microphone is connected to an automatically actuated switch which closes whenever the pick-up microphone detects certain ambient sounds extraneous to the system. The latter automated switch assembly is directly interconnected with a voice compressor assembly, and then directly to an amplifier to provide minimal amplification of such extraneous sounds.

Abstract: A device for facilitating the cutting of glass into a plurality of similarly sized shapes, such device comprising a frame member having a longitudinally extending base member which is pivotally mounted on a relatively flat working surface; and affixed at the end of the longitudinally extending base member, which is opposite to the end which is pivotally mounted, is a longitudinally extending connecting bar, disposed generally perpendicular to the base member. Moreover, the upper part of the connecting bar member is affixed to a longitudinal slide member, with the connecting bar and the slide member all lying in the same horizontal plane which is disposed parallel and adjacent the working surface. Integrally affixed into the working surface is a depressed arcuate guide, such arc guide being adapted to receive in sliding fashion therein a portion of the bottom of the slide member.
