Inventor: PERITO RICHARD P
IPC: C09K21/02
Filed: 1993-04-15
Abstract: Sprayable fireproofing compositions for structural members such as steel columns are provided, as well as a method of applying multiple coatings thereof. The compositions comprise a Portland cement-based material, stucco, and an accelerator. The compositions eliminate the long setting times typical of Portland cement-based materials, and improve the hangability thereof. The product is produced by dry blending a mixture of Portland cement, stucco (calcium sulfate hemi-hydrate) and optionally, a stucco set retarder and shredded polystyrene aggregate. Upon the addition of water, sprayable slurries are formed which can be pumped to the point of application. An accelerator is added in close proximity to the point of injection. Other additives may also be included, such as starch, adhesives and cement strength enhancers. The slurries adhere to the structural member in the slurried state and after setting to provide excellent fire and heat protection. Because of the relative quick setting time of the slurry upon spray application, multiple coatings can be applied within the same working day.

Title: Method and an apparatus for charging a rechargeable battery
Inventor: REIPUR JOHN
IPC: G01R31/36
Filed: 1992-02-14
Abstract: A rechargeable battery is charged by connecting the terminals of the battery to an electrical power source. In order to avoid overcharging and undue temperature increase in the battery cell, the course of a least one charging parameter, such as the in-crease rate of the voltage, is surveyed during at least part of the process of charging the battery. This charging parameter surveyed is compared with a number of reference parameter courses representing idealistic or desireable processes of charging the battery for different starting states of charge of the battery. Such comparisons may for example be made by means of a microprocessor, which may also select the reference course with a starting state of charge similar to the actual starting state of charge of the bat-tery. Thereafter the process of charging the battery may be controlled so as to approximate the course of said charging parameter to the selected reference course. The charging voltage may be limited to a maximum value (Vmax). When such value has been reached the charging process may be terminated after a certain predetermined time period being one of the reference values.

Patent CA-2105982-A1 (CA)
Inventor: SCHNEIDER EDWARD T
IPC: F15B21/06
Filed: 1991-06-12
Abstract: A pressure vessel (A) is defined by end walls (16) and side walls (18). In the interior, a plurality of fins (12) define an assembly of thin passages (10) that are filled with a material (26) that expands as it changes from a solid to a fluid state. The passages are thin, on the order of 0.01 inches such that heat is transferred relatively quickly into and out of the material. The passages communicate with a manifold area (14) to a piston bore (40) or other structure (B) for converting fluid pressure into mechanical movement. The piston bore holds a low durometer seal (44), a higher durometer seal (46), and a movable piston (42). To generate rotary motion, the piston and vessel assembly are mounted for rotation about an eccentrically placed member (88). As the pressure vessel goes through heating and cooling reservoirs, the pistons expand and contract causing rotation (Figs. 5-7). In another application, at least two of the assemblies are interconnected by a heat pump (94) such that heat can be moved back and forth between the two. Additional heat pumps are provided for moving heat from the ambient air or other sources of heat to the pressure vessels (fig. 8). The actuator is also used to control a two position valve (fig. 10) and a three position valve (Fig. 1 I). A pair of actuator vessels (170, 172) are connected by a common heat transfer device (174) for causing differential movement between pistons (176, 178, Fig. 13).
