Abstract: An electronic security system includes an electronic lock mechanism (201) and an electronic key (101 and 104), each of which is provided with a microprocessor controller  (501) and a memory  (502)  storing data including an ID code.   The lock microprocessor  (601)  changes the ID code stored in its memory (602) upon the operation of the lock by a correct key. The key (101) can only be used to operate the lock once, and thereafter must be reprogrammed by a host computer with the updated ID code for the lock.  The electronic lock operates a solenoid (209) which retracts a bolt blocking mechanism (210) which prevents the unlocking of the bolt (202) even when a key having the correct mechanical key cuts (102) inserted into the lock.  Power for operating the electronic lock as well as the solenoid is provided by a power supply within the key (504).

Abstract: A protective liner system and method for installing the same on a structure such as a dump truck hopper are disclosed.          The protective liner system comprises a plurality of  sheet members securely fastened to the otherwise exposed surface of the structure.  The edges of adjacent sheet members are joined by an overlapping sliding joint wherein the sheet members are in first-edge to second-edge facing relation such that the first-edge of one sheet member is spacially opposed the second-edge of a second sheet member so as to form a gap therebetween.  A first spanning member contacts the first faces of the sheet members and is securely  fastened  to  the metal  structure  so  as  to  be in intimately contacting sliding relation to the first faces of the sheet members.   The sheets are also placed in first-end to second-end juxtaposed relation such that a downwardly sloped portion of the first-end of one sheet functionally contacts a second-end on the first face of the other sheet, so as to create a joint that is substantially flush at its top face.   The protective  liner  system thus  configured allows  for  lateral expansion of the sheet members so as to preclude buckling of the sheet members during expansion and loss of sealant placed between adjacent ends of the sheet members.

Title: Thermosyphon with evaporator having rising and falling sections
Inventor: LONG ERWIN L
IPC: F28D15/02
Filed: 1993-01-20
Abstract: A thermosyphon for removing heat from a permafrost foundation is compared of a sealed container containing an easily vaporizable liquid. The container has a condenser part, which is exposed to temperatures below the condensation temperature of the liquid, and an evaporator part in which the liquid is intended to boil. The evaporator part is of double-tube structure with a supply tube and a return tube connected to each other at a paint distal from the condenser part. The return tube has a riser with an opening at one end which is inside the supply tube and has a much smaller cross-sectional area than the supply tube around it. The tubes may have both rising and falling sections but the opening of the riser is sufficiently higher than these sections of the tubes such that the hydrostatic pressure causes the liquid in the evaporator part to flow from the supply tube into the return tube as the liquid forms bubbles in the evaporator part and overflows from the riser opening.
