Title: Ozone mixing test apparatus
Inventor: SZOPINSKI RYSZARD
IPC: D21C9/153
Filed: 1993-04-07
Abstract: ABSTRACT OF THE DISCLOSURE    Laboratory equipment for practicing experiments and mixing ozone with medium consistency cellulosic pulp allows precise control of the timing and amount of ozone injected into the mixer, providing a method of testing that is more accurate than prior methods. An injection cylinder and fluidizing laboratory mixer are utilized.  Pulp is fed into the mixer, the cylinder is charged with a known predetermined amount of ozone containing gas, the ozone containing gas is injected from the cylinder into the mixer, the mixer is operated to effect mixing of the ozone containing gas with the pulp for a predetermined period of time, and then gas containing residual ozone (which has not reacted with the pulp) from the mixer is vented from the mixer, including by utilizing a purge gas such as nitrogen.  The ozone is created by an ozone generator which continuously operates.  A three-way valve directs the output of the ozone generator to an ozone destruction device when the ozone is not being charged into the cylinder.  A residual ozone analyzer is disposed in the vent of the mixer between it and the ozone destruct system, and may comprise a pair of potassium iodide solution containing vessels. Automatic valves and controls are provided for completely automating the testing sequence.

Title: Fully automatic energy efficient lighting control and method of making same
Inventor: ELWELL BRIAN E
IPC: H05B37/02
Filed: 1991-11-27
Abstract: A fully automatic and energy efficient lighting control or light switch (2, 150) comprises different settings, preset by a user, and activates all or a portion of at least one bank of lights (300, 320) upon detecting occupants within a room. In one embodi-ment, the light switch detects doppler-shifted, reflected ultrasonic waves caused by occupant motion within the room. In an auto-matic mode, the light switch (2, 150) is configured to automatically switch from an initial sensitivity level for detecting motion within a short range (260) therefrom, to a higher sensitivity level for detecting motion anywhere within the room. After the room is empty or no motion is sensed, the light switch (2, 150) is configured to turn the lights off following a variable time delay. The light switch (2, 150) returns to its initial low sensitivity level following a predetermined grace period which begins once the lights are turned off. The lights (300, 320) can be turned off manually when the light switch (2, 150) is in its automatic mode, in which case, the light switch (2, 150) continues to operate at the higher sensitivity level. When motion is no longer detected, and following the variable time delay and predetermined grace period, the switch (2, 150) automatically returns to an automatic "on" state. In an alternative manual mode, the light switch can be activated manually and deactivated both manually and automatically. In its manual mode, the light switch (2, 150) is configured to deactivate the lights (300, 320) upon sensing no motion and is configured to reactivate the lights automatically within the predetermined grace period upon sensing motion.

Title: Method for producing a selectively surface hardened cast iron part
Inventor: KOVACS BELA V
IPC: C21D1/06
Filed: 1993-05-27
Abstract: A method for producing a selectively surface hardened cast iron part includes the steps of (a) heating the part to a desired austempering temperature of between about 450°F and about 800°F until the entire cast iron part  possesses  the  desired  austempering temperature substantially uniformly throughout it; (b) heating only the surface of the cast iron part to an austenitizing temperature of between about 1500°F and about 1800°F by immersing the cast iron part in a molten lead or tin bath until a desired thickness of an austenite layer is formed on the surface of the cast iron part, without substantial heating of the interior of the cast iron part;  (c) quenching the surface-heated cast iron part in a non-liquid  quenching  bath  atmosphere, i.e.  a  gaseous atmosphere, maintained  at  the  desired  austempering temperature, for a time adequate to transform the surface austenite layer to an ausferritic structure; and (d) cooling the cast iron part before bainite is formed in the heat-treated surface layer.  In this manner, only the heat-treated surface layer of the cast iron part is hardened,  because  it  is  quenched  from  both  sides simultaneously from two sources: self-quenching by the interior of the part,  and external quenching by the austempering atmosphere.  Typical heating times in step (a) are between about 10 minutes and about 10 hours, and in step (b) are between about 3 seconds and about 10 minutes.   The quenching time in step (c) is typically between about 15 minutes and about 8 hours.   These temperatures  and  times  usually  yield  a  hardened ausferritic layer on the part having a thickness of between about on the order of 1/100 of a inch and about 1/4 of an inch.  Unlike hardened layers formed by flame hardening or induction heating, the layer that is formed is of a uniform thickness without regard to the shape of the part.  Moreover, again in contrast to such methods, at no time during the formation of the layer is the layer heated above the austentizing temperature. The disclosed method is particularly advantageous in that it eliminates the previously required quenching bath of oil or molten salt, yet provides a uniform hardened layer more quickly than prior methods, thereby providing a better surface hardened cast iron part at a lower capital and production cost.

Patent CA-2100371-A1 (CA)
Inventor: CACCAVALE CHARLES F
IPC: B22C9/10
Filed: 1993-07-13
Abstract: A method of making a casting having an internal passage involves the steps of forming a core having an external surface configured to form the passage in the casting and having a plurality of integrally formed protrusions extending from the external surface at stressed regions thereof (e.g., thermally stressed regions) prone to be distorted from a master core con-figuration, and positioning the core in a pattern molding cavity by engagement of the protrusions with rigid walls defining the molding cavity such that the core is conformed substantially to a predetermined and/or empirically determined relationship between the master core configuration and the molding cavity as if the core corresponded to the master pore configuration.      A fugitive pattern corresponding to the casting to be formed is then molded about the external surface of the core while the core is supported in the aforementioned relationship relative to the molding cavity, whereby the wall thickness of the pattern is controlled about the core. A ceramic shell mold is then invested about the pattern and core such that the protrusions can engage the mold in the event of core movement during subsequent steps. The molded pattern is selectively removed from the invested shell, leaving the core spaced from the shell in a shell mold casting cavity by the protrusions in accordance with the aforementioned relationship between the master core configuration and the pattern molding cavity, whereby the wall thickness of the casting formed therein is controlled. Molten metal is then solidified in the shell mold about the core. After the metal is solidified, the shell mold and core are removed by conventional techniques to free the casting.      The casting may have holes in the wall thereof in communication with the internal passage where the protrusions formerly resided.

Title: Three stage cooling of porous materials
Inventor: RICCIARDI MICHAEL A
IPC: C08G101/00
Filed: 1992-07-30
Abstract: A process for rapidly cooling porous foam material to prevent oxidation or autoignition of said foam. The process includes a first cooling step wherein cooled ambient air is drawn through the foam block (1) thereby cooling, dehumidifying and removing fumes from said block before being vented, a second cooling step wherein cooled ambient air is drawn through the block condensed and redeposited within the block, for further cooling thereof, with sublimates in the block, and a third cooling step wherein ambient air is drawn through the material so as to remove remaining fumes, heat and moisture therefrom. The process of the present invention advantageously utilizes a foam formulation which includes an increased percentage of water for providing adequate foaming of the material while minimizing or obviating the need for including toxic auxiliary blowing agents in the formulation. In addition, the formulation may also have a lower TDI index as compared to formulations utilized in conventional cooling methods because TDI is condensed and recycled back into the foam. An apparatus especially configured and adapted for practicing the process of the present invention is also disclosed.

Title: Label printer and dispenser
Inventor: SCHWARZ WERNER R
IPC: B65C1/02
Filed: 1992-09-02
Abstract: The device (10) for the printing and dispensing of labels (16) sticking on a strip-shaped liner (14) of carrier material is provided with a printing means (46) which, in advancing direction of the liner, is arranged at a distance before a separation means (54) for separating an already printed label from the liner. For providing the liner with labels over the largest possible area on the liner surface, the labels are arranged on the liner relatively closely adjacent to each other. To make it possible that, after dispensing of one label, printing on the following label can start at the leading edge thereof, the liner is moved backwards after dispensing of one label until the front edge of the next label is positioned before or level with the printing means. This control sequence allows processing of liners in which the distance between adjacent labels is smaller than the distance between the printing means and the separation means. If the labels are arranged directly abutting each other, the position of the labels is detected by temporarily bending the liner within part of the transport path (34, 36). Thus, the gap between adjacent labels will widen and accordingly be detected by a light beam (40, 42).

Filed: 1993-05-07
Abstract: 2118024 9323715 PCTABScor01 A fire control system (55) azimuth command and elevation command provides a flight control system attitude reference in response to operation of the flight control system in a coupled aiming mode. The coupled aiming mode is engaged in response to the continuous operation of a pilot switch (920), the azimuth command and elevation command being below respective threshold magnitudes (940, 941), and the operation of the fire control system (55). During operation in the coupled aiming mode, the azimuth command and elevation command replace the yaw attitude feedback error signal and pitch attitude error signal, respectively, as the aircraft attitude reference. During integration of the fire control system and the flight control system, the flight control system is made less sensitive to small pilot command stick inputs below a stick input threshold magnitude, so that small or inadvertent pilot commanded yaw and pitch maneuvers will not affect the yaw and pitch attitude reference commanded by the fire control system azimuth and elevation commands. However, intended pilot commanded yaw and pitch maneuvers (70) maintain full authority at all times.
