Abstract: A B S T R A C T        Process and apparatus for determining the presence and location of inclusions within gems.  A gem is initially scanned or irradiated along X and Y co-ordinates by a light bundle whose cross-section perpendicular to the scanning tracks is at least equal to the spacing between adjacent tracks.  The intensity of light passing through the gem is measured to determine the possible existence of any inclusions.  The gem and the source of light are next moved relative to each other along the Z co-ordinate, so that the focal point of the light rays moves within the gem to pinpoint the location of any inclusions therein.

Abstract: ABSTRACT             The horizontal burning rate of polyester fiberfill coated with cured polysiloxane and/or bonded with a synthetic resin is reduced by incorporating small amounts (2 to 20% by weight) of an organic filamentary marterial that maintains its physical integrity when exposed to a small flame.  The pre-ferred material is poly(p-phenylene terephthalamide).  This has particular application to silicone-slickened polyester staple fibers used for fiberfill, and articles therefrom, but has application also to silicone-slickened polyester filler tow, to resin-bonded polyester staple fiber batts, whether silicone-slickened or not, and to resin-bonded polyester filler tow.

Abstract: IMPROVED TRACTOR                              ABSTRACT           An improved tractor having a front section pivotally coupled to a rear section wherein the front section has a radiator, front wheels, and a tiltable cab.           Wrapped around the radiator at the extreme end of the front section is a combination bumper and storing area for hydraulic fluid.  The additional weight of the hydraulic storing area in front of the radiator substantially prevents front wheel slippage.  Also mounted on the front section is a tiltable cab having air conditioning and a pedestal chair seating the operator.  The air conditioning system is designed to force air from both a forward intake and a rearward intake between the top of the cab and a dome-shaped roof having a plurality of holes formed therein for uniformly distributing the air from the front and rear conditioners over the operator.  The pedestal chair is designed to have forward and rearward movement as well as pivotal movement.  Upwardly extending on one side of the chair from the pedestal is an arcuate support carrying the fluid power cables and terminating in an arm rest having hydraulic controls disposed in the front thereof.  The front and rear sections of the tractors are designed to be of equal distance from the center coupler so that perfect tracking of the rear wheel in the paths of the front wheels is accomplished.  Finally, the fenders of the tractor are designed to have mud balls substantially eliminated from forming thereunder.

Abstract: IMPROVEMENTS RELATING TO CEMENT KILN PLANTS            ABSTRACT     A method is disclosed for operating a cement kiln plant in which impurities in the form of alkalis are present in vapour form in the hot dust laden gases generated in the kiln.          According to the method, a portion of the hot kiln gases are directed upwardly through a first riser pipe which communicates with the kiln exit gas opening and thereafter they are separated from the gases and directed to the bottom portion of a second riser pipe having its lower end open to the atmosphere.  Relatively cold atmospheric air is directed upwardly through the second riser pipe so as to contact the kiln dust particles separated from the by-passed kiln gases of the first riser pipe thus permitting the kiln dust particles to be cooled by the cold air while causing the air to be heated.  The velocity of the cold air directed through the second riser pipe is preferably controlled such that the heavier of the alkali kiln dust particles are permitted to fall downwardly through the second riser pipe countercurrent to the flow of air while the lighter of the kiln dust particles are entrained in the upwardly flowing air. Ultimately the kiln gases from the first riser pipe are combined with the preheated air from the second riser pipe and the combined gases may be directed to preheaters.  Thus the method permits the removal of the heavier alkali laden particles from the cement kiln system by merely removing those particles from the second riser pipe.  A cement kiln plant for practicing the inventive method is also disclosed.

Granted: 1980-11-18
Abstract: ABSTRACT     Disclosed is a liner for concrete forms and method for making poured concrete walls comprising a liner body constructed for insulative material and shaped for position-ing between a pair of interconnected form panels.  The liner body has opposing sides, one of which is positioned abutting an interior surface of a first one of the panels.  The other side of the liner body has a textured, decorative surface spaced from the other panels, and is contoured for molding concrete poured therebetween.  A plurality of similarly shaped liner bodies are placed in a side-by-side relation-ship along the interior surface of each section of form panels, with the textured surface of each oriented inwardly.          Unsolidified cementitous material, such as concrete, is poured into the cavity having a single insert therein or formed between opposing inserts, and is cured to a solidi-fied state.  The form panels are disassembled and removed, and the liner on the exterior side of the dried concrete wall are bodily separated therefrom, exposing a contoured, decorative, optional aethetic, exterior surface portion.          The liners on the interior side of the wall are securely attached to the wall, thereby forming an integrated wall structure.

Title: Electric cigar lighter
Inventor: HORWITT LAURENCE G
IPC: F23Q7/02

Granted: 1982-03-09
Abstract: ABSTRACT       An electric cigar lighter for automobiles and the like, comprising a holder device presenting outwardly facing socket, and an ignitor plug receivable in the socket.  The plug comprises a manually operable part, and carries a heating element which is electrically connected in circuit with a normally-closed heat-responsive switch that is disposed in the holder device.  The socket, in addition to its grounding circuit, has a "hot" contact which is engageable with a co-operable contact on the plug to effect the circuit through the heating element when the manually operable part is depressed.          The holder device also carries, a bimetallic member which is engageable with one of the parts of the switch.  The member normally occupies a closed-circuit position wherein it is separated from the one switch part.  When the manually operable part of the ignitor plug is depressed and held, the cooperable contact of the ignitor plug is about into engagement with the "hot" contact of the socket, this effecting energization of the heating element and resulting in rapid heating of the bimetallic member.  After several seconds, the member snaps to a circuit-opening position wherein it causes disengagement of the switch parts, and results in de-energization of the element.          Central portions of the bimetallic member are free and not at-tached anywhere to any parts of the switch or socket, but in-stead are merely disposed in close proximity to one switch part, such that the member can quickly effect opening of the switch without need for mechanical  securement of its central actuator portion.  The advantage of the present construction over that of prior devices is that there are eliminated the many problems which were previously associated with conventional fastenings made to a bimetallic member, such as securing a contact to the member, etc. Improved reliability and operation, together with significantly lower manufacturing and assembly costs, are thus realized.
