Title: Gas grill cooler shelf
Inventor: HANAGAN JOSEPH J
IPC: A21B1/00
Filed: 1989-02-22
Granted: 1991-10-01
Abstract: ABSTRACT   The tubular frame of the grill cart forms a laterally extending shelf with opening into which an insulated container removably nests.  A heat  shield  of  folded metal with  slotted  apertures  to  inhibit heat transfer by conduction protects  the container  from the  intense  heat developed by the grill by deflecting radiated thermal energy and by inhibiting air current convection heat transfer.  The insulated container may  hold  either  refrigerated  or  heated  items  and  features  opposing carrying handles which rest upon the frame to support the container with its lid in a generally horizontal plane.  The lid in this position may be used as a countertop work space while tending the grill.  The lid may also be flipped over to expose a contoured surface with recess compartments for holding beverage containers, plates and trays.

Abstract: METHOD AND APPARATUS FOR DETECTING   A DESIRED TELEVISION SIGNAL                    ABSTRACT OF THE DISCLOSURE         A detector indicates the presence of a desired signal when both of at least two conditions occur.  The first condition requires the presence of a selected frequency in an input signal and a second condition requires the amplitude of the input signal at the selected frequency to fall within a predetermined range.  A third condition requires that one or both of the first and second conditions have a duration of at least a selected period of time.          In one embodiment, the detector indicates the presence of a stereo audio signal in a television transmission program when (1) a pilot frequency (15.734 khz) is present in the composite baseband, (2) the signal amplitude at the pilot frequency corresponds to a fre-quency deviation of not more than 5.5 khz and not less than 4.5 khz from the 4.5 mhz carrier frequency, and (3) the two afore-mentioned conditions exist for a predetermined period of time, preferably about one millisecond.  In another embodiment, the detector indicates the presence of a second audio program (SAP) in a television transmission program when (1) the SAP carrier fre-quency (78.67 khz) is present in the composite baseband, (2) the signal amplitude at the SAP carrier frequency corresponds to a deviation from the sound carrier signal of not more than 16.5 khz and not less than 13.5 khz, and (3) the aforementioned two con-ditions are present for a predetermined period of time, preferably about one millisecond.

Abstract: Abstract A process and apparatus is provided for cutting multiple plies of thermoplastic material having thickened sections, such as defined by cross-sections of matable parts of a zipper closure formed in the material, and for concurrently sealing the severed margins of the material which includes sealing the severed zipper closure portions thereof.  The process and apparatus perform the operative steps of:  first, preblocking the thickened material adjacent to the zipper closure portions of the material in areas thereof to be severed and sealed; then applying heat and pressure to the thickened material and remaining sections of the material in those areas to render the material tacky and temporarily stick the multiple plies together in those areas; and thereafter, contacting those areas of the material with a heated cutting and sealing element in order to sever all of the multiple plies and seal the severed margins thereof.  Further, after the application of heat and pressure, the zipper closure portions of the material in the areas thereof to be severed and sealed are preheated.  Also, after the margins of the multiple plies of material are severed and sealed, pressure is applied to the zipper closure portions at the severed and sealed margins to ensure sealing thereof.     36,311-F

Abstract: Abstract of the Disclosure A  reconditioned  tool  comprises  a  cylindrical insert cut from a damaged tool, such as a hog mill, with a milling  face  formed  on one end and a transverse dovetail tenon cut in the other end.   The dovetail tenon engages a transverse dovetail mortise in the end face of a cylindrical holder.   A transverse slot in the holder splits the end of the holder into two axially extending end sections each of which includes one-half of the dovetail mortise.  A clamping device, such as a bolt, draws the two end sections of the holder together to pull the insert firmly against the end face of the holder through wedging action of the two halves of  the  dovetail  mortise  against  the  dovetail  tenon.   A locking pin inserted through aligned transverse grooves in the holder and insert prevents lateral displacement of the insert relative to the holder.

Granted: 1993-09-07
Abstract: ABSTRACT         Title: FLUID SEPARATION APPARATUS            Apparatus for separating gases and liquids comprises a vessel adapted to receive a mixture of gas and liquid and consisting of an upper tank (1) and a lower tank (2) which are interconnected by a plurality of tubes (3,  4,  5).   A first one  (3)  of these tubes is centrally located in the upper wall of the lower tank (2) and the remaining tubes (4 and 5) are equi-spaced on either side of the central tube (3) and are also located in the upper wall of the lower tank (2).   A gas/liquid mixture is introduced into the upper tank (1) via an inlet nozzle (8)  and baffles (9) aid in separating the gas from the liquid.  The separated gas can be collected from an outlet (12) while the liquid passes down the tubes into the lower tank (2).   The level of liquid in the lower tank is adjusted so that the liquid extends up into the tubes (3, 4, 5).  As a result, there is very little interface between the gas and liquid and separation is not impaired even if the vessel is subjected to movement caused by,  for example, wave action on a floating vessel or platform.

Abstract: For the preparation of titanium dioxide by the sulphate process, titanium slag and ilmenite are used as starting materials and are digested simultaneously but separately, i.e. different amounts of 98.5% strength and 85% strength sulphuric acid are added to them, the temperatures being slightly below the starting temperatures and the digestion reactions being initiated by adding a small amount of superheated steam. After the digestion, the two mother liquors are mixed and are processed together to give TiO2, the 23% strength dilute sulphuric acid obtained in the process being concentrated to about 85% with isolation of metal salts and being recycled. Highly concentrated sulphuric acid, preferably obtained by roasting the metal sulphates obtained in the process, is predominantly used for the titanium slag digestion, while the excess concentrated 85% strength sulphuric acid is used predominantly for the ilmenite digestion, so that the dilute sulphuric acid obtained can be virtually completely reused in an economical manner.

Abstract: An apparatus for producing hot water. A heat exchanger has a primary circuit which receives water from a hot water source and delivers the spent water back to the source. A secondary circuit through the heat exchanger receives unheated water and delivers it as hot tap water. A pump is connected in the line between the hot water source and the primary circuit of the heat exchanger, and a shunt bypass is connected in parallel with the series comprising the pump and the primary circuit of the heat exchanger. A sensing means such as a temperature sensing means senses the commencement of water flow through the secondary circuit and in response thereto operates the pump. Another temperature sensing means measures the temperature downstream from the primary circuit and in response thereto controls the distribution of fluid downstream from the primary circuit of the heat exchanger as between the shunt and the return line to the hot water source.
