Title: Double-hung tilting sash type window system
Inventor: EVANS HAROLD H
IPC: E05D15/22
Filed: 1993-06-23
Abstract: A window having a frame with at lest two oppositely disposed side members, a top member, and a bottom member. Operably connected to each frame side member is a jamb liner having a front face and at least one jamb channel. Mounted within the frame is at least one sash having two oppositely disposed sides. The sash tilts away from the frame for easy cleaning. Within each jamb channel is a locking slide block for slidably and rotatably mounting the sash to the frame. A plough extends from the face of each jamb liner in the direction of the opposite frame side member. Each side of the sash has a sash groove for slidably mounting the sash in the frame by receiving adjacent ploughs. The plough and sash grooves have interlocking edges which engage to resist unintentional tilting of the sash. The jamb liner is mounted for lateral displacement from a first position wherein the plough is engaged with a sash groove to a second position wherein the plough is at least partially retracted from the groove so that the window can be tilted. There is a counterbalance operatively connected to the frame which has a counterbalance tab with an elongated portion having a flange proximate one end far connecting the counterbalance to the locking slide block.

Inventor: BAIRD RANDY K
IPC: B65G27/24
Filed: 2003-12-18
Abstract: A conveying apparatus comprises an elongated conveying bed which includes a proximal end and a distal end. A support structure for the conveying bed accommodates vibratory motion of a portion of the conveying bed extending from the proximal end a substantial distance toward the distal end but dampens vibratory motion at the distal end. In addition, a piezoelectric driver is operatively connected to the conveying bed adjacent the proximal end. Consequently, operation of the piezoelectric driver will induce a wave motion in the conveying bed which will effectively convey a material from the proximal end to the distal end.
