Title: Swath turner
Inventor: GERBRANDT HAROLD F
IPC: A01D78/00
Filed: 1994-06-20
Abstract: A swath turner for inverting a swath or windrow of cut crop has a pickup followed by a moldboard. The moldboard extends rearwardly from one side of the pickup and across the direction of travel. It engages one side of the swath or windrow as it leaves the pickup discharge and inverts the swath or windrow before it falls on the ground. As the inverted swath or windrow is deposited onto the ground, the tail end of the moldboard forces it down on the ground. A swath setter may follow the inverter to set the swath firmly to avoid subsequent wind losses.

Title: Beam steered laser iff system
Inventor: WOOTTON JOHN R
IPC: G01S17/74
Filed: 1993-03-31
Abstract: A system (10) for friend-or-foe identification (IFF) comprises an interrogator unit (18) carried on a first platform (T1) for generating and transmitting a laser beam. A control unit (22) selectively directs the transmitted laser beam toward a second platform (T2). A coding/decoding unit (28) encodes an IFF interrogator message with which a portion of the transmitted laser beam is modulated. A laser reflector (30) carried on the second platform receives the coded laser beam. The reflector is a normally passive reflector which is activated by receipt of the transmitted laser beam. The reflector responds to the IFF message contained in the received laser beam by modulating the unmodulated portion of the transmitted laser beam. This newly modulated portion of the laser beam is reflected back toward the first platform. The coding/encoding unit decodes on the first platform, receives and decodes the response, and determines if it corresponds to a predetermined response which identifies the second platform as a "friend".

Title: Electronic devices with electronic components carried upon a substrate
Inventor: HUGHES RICHARD P
IPC: H01L23/367
Filed: 1995-06-07
Abstract: An electronic device with an EMI shield surrounding an electronic component on a substrate. A heat sink extends through an opening in the shield from heat conductive contact with the component to a position outside the shield. The heat sink operates also in an EMI shield capacity. The shield is stressed to hold the heat sink positively in heat conducting contact with the components. The shield preferably has cutting teeth which cut into the heat sink as the latter is passed into the aperture. With the inserted part of the heat sink being cylindrical, rotation of the heat sink causes the teeth to move up the inserted part to stress the shield and urge the heat sink against the component.

Patent CA-2160522-A1 (CA)
Title: Material scoring apparatus
Inventor: FLETCHER DONALD C
IPC: B26B29/06
Filed: 1995-10-13
Abstract: In order to facilitate a scoring of a sheet of material such as drywall, plasterboard, wallboard or the like, an apparatus includes a pair of arms each having an upper end and a lower end where the arms are spaced apart to define a sheet-receiving channel for receiving the sheet of material therebetween.  The lower ends of the arms define an entry point for the sheet of material so the sheet of material can be placed between the arms and within the sheet-receiving channel with the sides generally perpendicular to a plane defined by the arms. The upper ends of the arms are connected to accommodate relative movement of the lower ends of the arms toward and away from one another. The apparatus includes a cutter for scoring at least one side of the sheet of material which is operatively associated with at least one of the arms at a point located generally remote from the upper end thereof. It also includes an elongated channel operatively associated with at least one of the arms for engaging the elongated edge of the sheet of material when it is positioned in the sheet-receiving channel. The elongated channel is positioned between the arms so as to guide the cutter along a line which extends generally parallel to the elongated edge of the sheet of material. The arms have a force applied to them at a point generally between the elongated channel and the upper ends of the arms to force the cutter into scoring engagement with the sheet of material. In order to make a tapered cut with the apparatus, a jig is provided in the form of a generally elongated channel-shaped guide carrying a stop that is adjustably positioned to cause the apparatus to be guided along a tapered line.
