Abstract: ABSTRACT OF THE DICLOSURE           The extent of non-uniformity of the teeth on a gear wheel or on a rack may be readily checked using a hand-held adjustable gauge providing a range of capability for teeth of differing pitch and size, the gauge having an adjustable datum screw by which the body of the gauge is positioned above the tooth tip so as to locate a depending mixed probe point against the flank of a tooth, closely adjacent the pitch circle, A moveable probe is set in cor-responding contracting relation against the flank of another tooth and a dial test indicator coupled thereto is centred to give a preliminary null reading.  The gauge is then relocated without further adjustment on another pair of teeth and the variation in pitch distance from the first or null value is read off the gauge as a positive or negative value indicating a lesser or greater pitch distance between the respective teeth.  In the case of very large gear wheels the outer diame-ter of the tip of the teeth may be centric to the pitch circle of the gear.  In such cases a band concentric with the pitch circle is machined, usually on the outer diameter of the gear, to facilitate accurate use of the gauge.

Abstract: ABSTRACT OF INVENTION         This invention relates to structural devices which in-clude intumescent material for the purpose or inhibiting the flow of heated air, smoke, and other products of extraordinary heat conditions, as in the case of a fire, from flowing therethrough.          In one emobdiment, useful as a tray for supporting insulated elec-trical conductors, a structure with double floor members spaced apart from each other, has convection holes in both of the floor members.  The holes in one of the members are out of alignment with the holes in the other, and the top surface of the lower floor member has intumescent material positioned thereon.  Thereby, upon exposure of the lower floor member to the heat of a fire for example, the intumescent material will expand, causing either or both the holes and the passageways that are described by the space between the holes of one floor member and those of the other floor member, to become blocked, thereby preventing the passage of heat, smoke and flame therethrough, to localize the fire, and deter consequent damage to the cables being held in the tray.

Abstract: ABSTRACT OF THE DISCLOSURE A process is provided for the continuous or semi-continuous pro-duction of hetero-macrocyclic compounds including lactones and cyclic ex-ters.  The process involves the catalyzed depolymerization of a linear polyester at an elevated temperature and under reduced pressure in the presence of a specified amount of monocarboxylate moieties and while pro-viding top-to-bottom mixing throughout essentially the total volume of the reaction mass.  The agitation is accomplished by conducting the depolymeri-zation in an inverted multiple-blade conical vessel wherein the blades have a helical configuration and are arranged to rotate throughout essentially the entire reaction mass and in close proximity to the interior surface of the conical vessel and in a direction which provides a downward flow within the reaction mixture.  The process prepares such macrocyclic compounds of good quality while minimizing the formation of undesirable by-products.

Abstract: ABSTRACT     An automatically actuated hydraulically pow-ered system for loosening the contents of a semi trailer dump body so that it will break away at its natural dump-ing angle.  The semi trailer dump includes a hydraulic pump which delivers hydraulic fluid under pressure to extend a telescoping hydraulic cylinder to raise the dump body to a dumping position.  An adjustable normally closed pressure relief valve is set to open when the pressure in the cylinder reaches a predetermined level corresponding to a dump body angle a few degrees less than the normal dumping angle for the commodity being dumped.  When the valve opens, hydraulic fluid is pump-ed to a hydraulic motor which drives a vibrator which is bolted to the dump body.  The vibrator loosens the material being dumped and prepares it to slide out of the body at its natural dumping angle.  When slideout begins, the fluid pressure in the cylinder drops, the valve closes and shuts off the hydraulic motor and vi-brator, so that the material being dumped slides out of the dump body naturally.
