Title: Method of selecting input apparatus
Inventor: IIJIMA YUKO
IPC: H04N5/44
Filed: 1995-07-28
Abstract: In  a  system  wherein  a  plurality of  electronic apparatuses are connected by a communications control bus for communication between those electronic apparatuses, each of the electronic apparatuses selects an input apparatus by sending an inquiry to all other apparatuses in the system on whether they can output data, displaying the apparatuses which respond that output is possible as candidate input apparatuses, and selecting the input apparatus from among the  candidate  input apparatuses.    For  an electronic apparatus which can not output data,  the reason for such impossibility to output data can be displayed at either the apparatus incapable of outputting data or the apparatus which is to select an input apparatus.   Input apparatus selection can be also performed using a list constituted by still images created from the image data supplied by other apparatuses.

Title: Device for indicating a faulty condition of an electrical apparatus, in particular of a surge arrester
Inventor: SCHMIDT WALTER
IPC: H01T1/12
Filed: 1995-10-12
Abstract: The indicating device (3) is used for signalling a faulty condition of an electrical apparatus, in particular of a surge arrester (1). It contains a sensor (resistor 10) which is located in an insulating material housing (6) and is intended for detecting a fault current flowing through the apparatus, as well as a two-piece metal housing (4) surrounding the insulating material housing (6). The sensor (10) and the insulating material housing (6) are part of a switching element (5). This switching element (5) causes the insulating material housing (6) to spring apart, by the formation of compressed gas, when the fault current occurs and displaces the two parts (shells 12, 13) of the metal housing (4), making the indicating element (16) visible and forming a DC connection which carries the fault current.

Abstract: A reduced waiting time drilling jar (1) includes a mandrel (2), a housing (3) telescopingly positioned about the mandrel (2), and first and second pistons (89, 111) positioned axially between the mandrel (2) and the housing (3). The pistons (89, 111) are spaced longitudinally apart, forming a substantially sealed chamber (88) therebetween. The first piston 89 has a first and second substantially parallel flow passage (94, 200) formed therein and extending longitudinally therethrough to provide first and second flow characteristics. A valve (204) is hydraulically connected to the second flow passage (200). The valve (204) is translatable between first and second operating positions, wherein fluid flows relatively freely through the second flow passage (200) in the first operating position, but is restricted in the second operating position. A pressure relief valve (206) is hydraulically coupled to the substantially sealed chamber (88), and mechanically coupled to the valve (204), wherein movement of the pressure relief valve (206) biases the valve (204) between its first and second operating positions in response to the pressure in the chamber (88) rising above a preselected value.

Abstract: A seat track apparatus of a vehicle for retaining a slide member between a lower seat track and an upper seat track of the seat track apparatus. The seat track apparatus provides a channel in the lower seat track having at least one longitudinally extending contact surface. The slide member has a shape complementary to the channel and is disposed within the channel with at least one contact surface in contact with the contact surface of the channel. The slide member provides a plurality of cylindrical pins projecting outward from the side wall of the slide member and extending through apertures in the side wall of the lower seat track. The engagement of the pins by the lower seat track aligns and restricts movement of the slide member in the plane in which the cylindrical pins extend therethrough. In a preferred embodiment, the slide member provides outwardly projections on the bottom wall of the slide member. Apertures provided in the bottom wall of the lower seat track receive the projections extending from the bottom wall of the slide member to maintain contact between the contact surface of the slide and the channel. In a second embodiment, the bottom wall of the lower seat track has a plurality of punched lanced upsets which abut the bottom wall of the slide member and prevent the bottom wall of the slide member from moving away from the channel thus maintaining contact between the contact surfaces of the slide member and the channel.

Title: A method and a device for separation and collection of substances floating in water
Inventor: BLOMBERG ERLING
IPC: B63B35/32
Filed: 1994-11-30
Abstract: The invention concerns a method and a device for separation and collection of substances floating in water by making use of a relative motion between the water containing the substances and a collection container having trapping means associated therewith. In accordance with the invention the water motion relatively to a collection container is made use of to create a circulating movement therein. The circulating movement is obtained by bringing the water to enter the collection container essentially tangentially with respect to the latter. The removal of the substances in question is effected in the circulating water flow. Cleaned water is evacuated along the collection container bottom.

Title: Pipe saddler gauge
Inventor: MORTENSEN GREG
IPC: G01B5/14
Filed: 1996-06-25
Abstract: A pipe saddle gauge is disclosed. The pipe saddle gauge provides a frame which adjusts in a telescoping manner to frictionally engage the base of a table type circular saw. The frame provides two pieces of square tubing, an inside tube telescopically carried within an outside tube. Each tube carries a bracket which engages the side of the table saw. An all thread rod carried within both tubes carries washers and threaded nuts at each end, thereby biasing the tubes together, causing the brackets to grip the sides of the table saw. A pivot post is supported by the frame in a vertical orientation. The pivot post provides a support tube, fixed to the frame, and a pivot tube carried within the support tube to rotate about an axis perpendicular to the horizontal. The support tube carries a gauge arm, which moves through a horizontal plane when the pivot tube pivots. The gauge arm carries an annular plate in an off-center manner. After a first cut is made, the pipe is rotated approximately 180 degrees before making the second cut. The gauge arm is then pivoted to a position next to the pipe. The annular plate is then rotated about the gauge arm, coming into contact with the first cut This rotates the pipe exactly 180 degrees. The gauge is then moved and the second cut made, finishing the saddle cut.

Abstract: Electrostatic spray device for coating powder or liquid with at least one charging electrode for electrostatic charging the coating material. The device has at least one, and preferably a plurality, of counter electrodes for the electrostatic removal of free charges (electrons or ions) from the stream of sprayed coating material adjacent a coating material discharge nozzle on the device. The counter electrodes are carried by a ring which is slipped onto a body of the device. A sleeve screwed onto the body holds the ring in an axial direction on the body. An electrical line for discharging the free charges from the counter electrodes is secured to the ring. The electrical line passes through and is confined in a bore in the body to prevent rotation and axial movement of the ring on the body. When the sleeve is removed from the body, the counter electrode ring and attached electrical line can be withdrawn from the body in the axial direction as a unit.
