Abstract:
An improvement to bimetallic pipe thermometers utilizing insulating tubular seats. The present invention improves the insulating tubular seat by closing off the tail slot along a proximal end thereof with a bridge or stop. Going forward, users of such bimetallic pipe thermometers no longer need worry about the tail of the bimetallic coil sensor unintentionally slipping out of what is currently an opened-ended tail slot.
Abstract:
A thermal sensor with a simple structure can secure the deformability of a bimetal, and accurately control the position of the bimetal, to increase the response speed (heat response) of the bimetal. The thermal sensor includes a bimetal, a case, and a cover member. A pressing portion is provided between the cover member and the bimetal to press the bimetal to a bottom portion of the case. The pressing portion is deformable in accordance with the deformation of the bimetal.
Abstract:
An arrangement for controlling a radiant heater of a cooktop comprising a power controller, a changeover switch and a rod controller in a first operating mode which provides for the interruption of operation at temperatures of approximately 600° C. at a first switching point on the rod controller. In a second operating mode, a switch in the rod controller is set to a different switching point resulting in interruption of the power supply at temperatures of approximately 80° C., so that the radiant heater makes it possible to keep food hot without boiling.
Abstract:
A released beam structure fabricated in trench and manufacturing method thereof are provided herein. One embodiment of a released beam structure according to the present invention comprises a semiconductor substrate, a trench, a first conducting layer, and a beam. The trench extends into the semiconductor substrate and has walls. The first conducting layer is positioned over the walls of the trench at selected locations. The beam is positioned with the trench and is connected at a first portion thereof to the semiconductor substrate and movable at a second portion thereof. The second portion of the beam is spaced from the walls of the trench by a selected distance. Therefore, the second portion of the beam is free to move in a plane that is perpendicular or parallel to the surface of the substrate, and could be deflected to electrically contact with the walls of the trench in response to a predetermined acceleration force or a predetermined temperature variation applied on the beam structure. Other beam structures such as a beam held at both ends, or a beam held in the middle are also possible. Several beam structures at different angles can be fabricated simultaneously and mechanical etching stops are automatically formed to prevent unwanted overstress conditions when manufacturing several beam structures at the same time. Beam structures can also be manufactured in three orthogonal directions, providing information on acceleration in any direction.
Abstract:
A temperature probe for use in a product flow line including a valve seat secured in the flow line, a valve stem and an orifice ring. The orifice ring is attached to the valve stem to define a pair of flow paths for product passing through the product flow line. One flow path is through the ring and the other is between the ring and the valve seat. A temperature sensing probe is carried by the valve stem and positioned in the orifice ring for sensing the temperature of the product in the flow line. A spring is connected to act on the valve stem and is responsive to changes in velocity of the product in the flow line to move the orifice ring toward and away from the valve seat to maintain the velocity of the product flowing past the probe constant.

Abstract:
A standard thermostatic switch, particularly one enclosed within a metallic casing, is provided with an insulating material, in the form of a sleeve, between the contacts or bimetallic elements and the metallic casing of the thermostat to aid in sealing the internal elements. The material is an aramide, particularly a copolymer of metaphenylenediamine and isophthaloyl chloride, particularly one marketed under the trademark "Nomex" by E. I. duPont deNemours & Co.
Abstract:
An improvement in a process for making modular iron is disclosed. Prior to casting, an iron melt which has previously been contacted with a graphite-spheroidizing agent is further contacted with an after-treating alloy agent containing about 0.8 to about 1.8 weight percent magnesium. Magnesium utilization in the pre-casting step is unusually high and the amount of graphite-spheroidizing agent can be substantially reduced without detrimentally affecting the metallurgical or physical properties of the resulting nodular iron product. The after-treating alloy agent is also claimed.
Abstract:
A temperature recorder which produces a continuous graphic record, scribed on tape, of the temperature existing in an enclosure (such as a refrigerated railroad car) curing a given period of time (e.g., the transit time of such a railroad car). The recorder comprises a guided, downwardly movable casesuspended by an upper-end anchored tape-which slowly gravitationally descends upon unwinding, under influence of the weight of said case and at a controlled rate, of the tape from a spool on such case, and the latter being fitted with a temperature-responsive device including a variably movable stylus which progressively scribes on the tape as the case so descends; the tape having a graph thereon which reflects the scribing in terms of temperature in relation to time.
Abstract:
Fishing apparatus for locating a desired water temperature layer in temperature-stratified fishing waters, the apparatus including submersible temperature sensing means and desired temperature signal means. In the preferred electrical embodiment, the temperature sensing means is an electrical switch having a bimetallic coil element as a temperature responsive contact, the other contact being adjustable to preselect the desired temperature, the contacts being connected by leads to the signal means comprising a modified flashlight providing a circuit including a battery power source and a lamp. The apparatus permits preselecting the desired temperature by setting the adjustable contact and locating the desired temperature layer on the first lowering of the adjusted switch, which is normally open at surface temperatures above the preselected temperature, through the progressively colder water until the bimetal closes the switch when the desired temperature is first reached, as indicated by the lighted lamp.
