Title: Thermal head with an improved protective layer and a thermal transfer recording system using the same
Inventor: NAKAZAWA KIYOHITO
IPC: B41J2/335
Filed: 1990-05-07
Abstract: A thermal transfer recording system using a thermal head is disclosed.  The thermal head includes protective films with different levels of thermal conductivity so that heat can be selectively and preferentially conducted to the protective film located right above the heat resistor layer,  resulting in improved  thermal  efficiency  and  reduced  power consumption.   Because the thermal head is of an end-face type, the tip of the thermal head can sufficiently protrude, which increases the stress to be applied by the thermal head onto a sheet of printing paper.  This enables printing on a rough sheet.  The sufficient protrusion of the tip also ensures an appropriate angle of an ink ribbon with respect to the sheet when the ink ribbon is applied to and removed from the sheet.  Thus, bi-directional printing can be performed, resulting in high speed printing.

Abstract: The method for reducing the nitric oxide concentration in the waste gas flow of combustion processes  consists of the introduction of chemicals, e.g, ammonia, sal ammonia, urea, calcium cyanamide, into the waste gas flow, wherein the waste gas flow is marked by an additional compulsorily produced strong turbulence and the waste gas flow is compressed prior to this turbulence zone.  The introduction of the treatment medium is effected shortly before the turbulence zone and the waste gas flow is relaxed and calmed subsequent to the turbulence zone.  In order to implement this method, a furnace is provided which comprises a grate (5) and a waste gas flue consisting of an ascending waste flue (10) and a descending waste gas flue (12) adjoining the latter.  The current flow of the waste gas flow is substantially S-shaped proceeding from the furnace grate to the downwardly directed waste gas flue (12), wherein the change of direction in the lower area is substantially smoother than in the reversing space (11).  In the upper portion (16) of the waste gas flue the waste gas flow is compressed by means of corresponding inclination and consequent constriction of the cross section of the waste gas flue.  Spray nozzles (26) are provided at the commencement of the upper portion (16) of the ascending waste gas flue in order to introduce chemicals. The introduction of the chemicals is effected shortly before the compression and the production of strong turbulence.

Title: Tamper-evident cap for containers
Inventor: WALLMAN IRWIN
IPC: B65D41/48
Filed: 1991-08-23
Abstract: PATENTS     ABSTRACT OF THE DISCLOSURE A push on cap for engaging a container neck is formed with inturned thickened flanges on its inner surface which cooperate with matching grooves in the container neck to retain the cap in place when the skirt is intact.  A circumferential groove is formed in the skirt intermediate the inturned thickened flanges joined with a second groove extending to the bottom edge of the skirt.  A tab projecting beyond the skirt is gripped and pulled causing the skirt to tear upward and then circumferentially thereby removing the lower thickened flange and permitting the top of the cap to be removed and reclosed.  A rigid circumferential flange on the exterior of the skirt is spaced above the level of the uppermost inturned thickened flanges and below the top of the cap has a angled gusset below the image to prevent removing the cap by prying upwards with a fingernail prior to removing the tear skirt.  The addition of the rigid circular flange and gusset and the uppermost thickened flange do not restrict the cap from expanding when pressed over the neck of the container due to the thin wall formation of the circumferential skirt of the cap.

Title: Method for avoiding terminal landing position initialization after power loss
Inventor: BARKMAN WILLIAM F
IPC: B66B5/02
Filed: 1992-01-08
Abstract: ABSTRACT      In an elevator system, primary marking means, placed near every floors and secondary marking means placed near alternate floors are read by a scanner.  Upon scanning, a marking number signal is provided indicating whether a primary marking means and secondary marking means, or only a primary marking means, is read at a floor level.   As the car moves in the hoistway, current position, direction of the  elevator  car,  and  the  marking  number  signal  is continuously updated and stored in non-volatile memory. Upon recovery from a loss of power, the car is moved to the next floor in the direction it was moving prior to loss of power. By comparing the marking number signal stored in non-volatile memory before power was lost with the marking number signal generated after regaining power, the stored position can be confirmed to be correct or, if incorrect, incremented or decremented by one floor, depending upon whether the car was moving up or down respectively, to identify the actual car position.
