Title: Counterbalanced reciprocating wobble plate mechanism
Inventor: PALM BERNHARD
IPC: B23D49/16
Filed: 1991-06-21
Abstract: A reciprocating saw is provided with a counterbalanced reciprocating drive having a jackshaft (24) on which primary and secondary wobble plates (30) are mounted. The wobble plates (30) drive a reciprocating saw spindle (40) and a concentric counterweight (46) in opposite directions to cancel out the induced vibrations. The spindle (40) reciprocates in a bearing sleeve (50) having a slot (52) through which the primary wobble plate arm (34) projects to drive the spindle. The counterweight (46) slides on the outside of the sleeve (50) and has a slot (58) which slides over the primary arm (34). The secondary wobble plate arm (35) drives the counterweight (46). The arms (34 and 35) are out of alignment to permit their strokes to overlap without collision. The wobble plates (30) are angled out of 180 DEG  so the spindle (40) and counterweight (46) reverse at the same time. The cutting stroke and speed of the saw are increased and vibration is insignificant. The drive system has many other uses. <IMAGE>

Title: Electromagnetic repulsion system for deicing aircraft surfaces
Inventor: ZIEVE PETER B
IPC: B64D15/16
Filed: 1992-01-02
Abstract: The deicing system includes a plurality of relatively thin, flat coils (10) positioned between an aircraft surface (12) and an outer sheet (14). If the aircraft surface is electrically conducting such as aluminum, such that eddy currents may be established therein, then the outer sheet (14) is resistant to eddy currents being established therein. An electrically conducting layer (54) (Fig 4) may be positioned between the coil and the aircraft surface to improve efficiency. If the aircraft surface (12) is resistant to eddy currents being established therein, then outer sheet (14) is electrically conducting. However, if an electrically conducting layer (76) (Fig 5) is positioned between coil (10) and outer sheet (14), the outer sheet (14) may be made from non-conducting material. A rapidly rising current through the coil will result in a rapid repulsion between the coil and the particular member which is electrically conducting, causing ice to be removed (shattered) from the outer sheet (14). <IMAGE>
