Abstract: A pillow has traditionally been used as a head and neck support providing relative comfort in the alignment of the cervical spine while lying on one's back, side or prone position while resting or sleeping. Improvements to the traditional pillow configurations and structures have been made to provide a better positioning of head and neck while lying on the pillow. These changes were made in order to provide a comfortable resting position as well as orthopedically correct alignment for head and neck. To do so a number of curvatures and shapes has been introduced to the traditional pillow structure. The TRAINING PILLOW is invented by considering these changes as well as addition of a certain considerations to provide the ultimate comfort and orthopaedic support. The fact that each individual has different neck and shoulder size has been ignored in all the pillows invented to this time. It has simply been assumed that one particular pillow size can provide the best support and comfort for every one as long as it provides a certain curvature. Although introducing certain curvatures in a pillow promotes proper head and neck positioning, size of the pillow's height and curvature has determintal rule in achieving comfort and support. Moreover, the position of body and consequently head and neck while lying on the pillow has been also ignored in the previous inventions. They have simply assumed that the same curvature is sufficient for lying supine (on the back), lateral recumbent (on the side) and prone (on the stomach).

Filed: 1996-04-09
Abstract: An improved locking mechanism for roll-up doors and the like (10) includes a hook member (13) and handle member (32) mounted on the outside of a door and a shoul-der member (54), arm (53), lever (61) and cam member (72) mounted on the inside of a door. The hook member is designed to engage a keeper (15) located on the floor of the container and also has a lug (29) the handle member selectively engages as it rotates, thus causing rotation of the hook member. The hook member is connected by a shaft (48) to the cam member on the inside of the door. When the cam member is locked against rotation by the lever, arm and shoulder member, attemps to rotate the hook member by rotation of the handle member will lead to the breaking away of the lug before the freeing of the cam member, shaft and hook member, thus, denying access to the container. The cam member is locked by the lever engaging a notch (71) in the cam member. The arm prevents forced rotation of the lever. The arm selectively rotates only in response to a tumbler (52) rotating the shoulder member against a post (58) mounted on the arm.

Title: Method and apparatus for reducing the generation of nox during combustion of coal dust
Inventor: LEISSE ALFONS
IPC: F23D1/00
Filed: 1996-04-26
Abstract: When coal dust is combusted in burners together with combustion air, especially when the coal dust is fed by way of a primary air as stream and in the form  of a coal dust/primary air mixture,  a primary gas with combustible, gaseous components is generated from  the coal dust/primary air mixture in the ignition zone of the burner by pyrolysis of the coal dust. In order to achieve a reduction in the NOx generated during combustion of the coal dust, the average ratio in the ignition region of the amount of oxygen in the primary gas to the amount  of  oxygen  required for complete  combustion of the volatile combustible components in the primary gas is lowered. This is achieved by either reducing the relative amount of oxygen in the primary gas and/or injecting a combustible external gas into the primary gas in the ignition zone.
