Appl. No.:

7/931750

Inventors:

Raytheon Company - Lexington MA

International Classification:

A21B 100

US Classification:

126 21A

Abstract:

A gas convection oven having a radiant burner and fuel feeding apparatus which enables the single burner to be operated in either a broil mode or a bake mode. In the broil mode, the radiant burner is operated in conventional manner with the flame being held by an inner screen to heat the outer screen to a radiant luminous temperature. In the bake mode, forced air is injected into the burner by a fan thereby providing a leaner fuel-air mixture with higher velocity. As a result, the flame burns outside the outer screen of the burner with the outer screen serving as a flame holder. Therefore, hot combustion gases as produced while the outer screen remains non-luminous.

Appl. No.:

5/781554

Inventors:

Edward J. Cook - South Hamilton MA

International Classification:

A01G 106

US Classification:

47 6

Abstract:

A method and apparatus are disclosed for making improved grafting joints between plant components, particularly woody plants. Selected plant materials may be grafted one upon another by cutting out two diametrically opposed, longitudinally diagonal sectors from each end of the plant parts to be joined. The sectors are of equal length on each plant part and are joined by slipping the sectored end of one plant part into the cooperating sectored end of the other plant part so that the parts interlock. The joint is then enveloped by tape or the like to seal the joint. Hand tools and semi-automatic machinery are disclosed for sectoring plants in a single operation and include radial cutting elements arranged perpendicularly to one another and adapted to make four simultaneous slits lengthwise and diagonally along the plant simultaneously removing the waste slit sectors.

US Classification:

252314

Abstract:

Method and apparatus for forming emulsions, a term used to include microemulsions. The leading edges of a plurality of sheets of an emulsion-forming liquid mixture are forced under pressure to impinge in a low-pressure turbulent zone of the liquid. The apparatus comprises a plurality of nozzles having elongated orifices to eject under pressure sheets of the emulsion-forming liquid and being arranged to effect impingement of the sheets along a common liquid jet interaction front. Inasmuch as the method and apparatus permit the formulation of emulsions without the use of any emulsifiers, there is provided a new class of emulsions, namely those essentially free of any emulsifying agents. The emulsions formed have a wide range of applications.

International Classification:

US Classification:

116 34R

Abstract:

A gas-actuated sound signal generator is provided to produce a simple, reliable sound signal of predetermined frequency, or combination of frequencies. The signal generator is intended for use primarily with a tire pressure sensing system on a vehicle as a means for transmitting the occurrence of a low tire pressure condition from a wheel to a microphone mounted in fixed position to the vehicle and connected via processing circuitry to an alarm near the operator. The device is operated upon the release of a small amount of air from the tire if the tire pressure drops, for example, below a preset limit. The air released from the tire flows into the signal generator and is converted into a sound signal for detection by the microphone. The signal generator is comprised of a cavity block, a shim and a cover. The block contains an entrance feed through which air is admitted as from the tire and a cavity spaced from the entrance feed.

US Classification:

422 681

Abstract:

A method of immobilizing and stabilizing an active biological receptor in a polymeric film and receptor-based biosensors for determining an analyte of interest in a sample. The receptor-based biosensors include a polymeric film having a biological receptor capable of binding an analyte of interest immobilized therein according to the method of the present invention and an electrical means for determining the presence and quantity of the analyte. In particular, acetylcholine receptor and opiate receptor have been immobilized in a polymeric film made by combining the receptor, a material (e. g. , bovine serum albumin, gelatin) capable of polymerizing and a polymerizing agent (e. g. , glutaradehyde).

International Classification:

B60C 2302

US Classification:

340 58

Abstract:

A pressure-responsive signalling valve for use on pneumatic tires is adapted to generate a highly efficient acoustical signal whenever the pressure within the tire falls outside of a predetermined range. The emitted signal is detected by means of an acoustical receiver which, in turn, is coupled to an alarm typically in the form of a warning light or audio device conveniently located within the vehicle to alert the driver. The acoustical valve employs a rolling or flat seal disc diaphragm and a flat sealing arrangement providing a positive sealing action, minimal friction, low hysteresis and extremely precise pressure response characteristics.

US Classification:

47 6

Abstract:

A method and apparatus are disclosed for making improved grafting joints between plant components, particularly woody plants. Selected plant materials may be grafted one upon another by cutting out two diametrically opposed longitudinal 90. degree. sectors from each end of the plant parts to be joined. The sectors are of equal length on each plant part and are joined by slipping the sectored end of one plant part into the cooperating sectored end of the other plant part so that the parts interlock. The joint is then enveloped by tape or the like to seal the joint. Tools for making uniform, repeatable grafting cuts are disclosed, including a simple gauge block with an integral cutter. The tool includes a socket bisected by a blade for making a cut of uniform depth lengthwise down the center of the plant and at least one gauging groove having a transverse cutting edge to make the transverse cut to remove the sector from the slit plant. Hand tools and semi-automatic machinery are also disclosed for sectoring plants in a single operation and include radial cutting discs arranged perpendicularly to one another and adapted to make four simultaneous 90. degree.

Abstract:

A system is provided for indicating excessive wear of brake linings. The system is usable on vehicles such as automobiles, cars, trucks and busses as well as aircraft or other applications where it is desirable to detect excessive wear of brake linings during operation thereof. The system includes an acoustical signal generating device having an air inlet normally closed by the brake lining. When the lining wears away to a minimum safe thickness, the inlet is opened and ambient air flows into the generator to produce an acoustical signal. An acoustical receiver is positioned in spaced operative relation to the brake system and responds to the acoustical signal to provide a warning indication on the dashboard, for example, of the vehicle so that the operator of the vehicle will be alerted to the worn brake condition.
