Patent number: 4751361Abstract: An automatic TW (traveling-wire) electroerosion machining system for machining a plurality of workpieces of different types required to acquire different contours includes a TW machine having a wire setting unit and located adjacent a predetermined path. A work dispensing unit successively dispenses the different workpieces onto the path from a store thereof located adjacent the path. This unit and a work handling and transfer unit operate under control commands from an NC unit and, in conjunction with the TW machine with the wire setting unit to carry out a plurality of work processing operations sequentially. In each operation, each individual workpiece selected from the store is transferred as it is carried on a pallet for loading onto and unloading from the TW machine. The electrode setting unit on the machine acts both to form a start hole and thread a wire-type electrode through the formed hole in the workpiece.Type: GrantFiled: April 15, 1986Date of Patent: June 14, 1988Assignee: Inoue-Japax Research IncorporatedInventors: Kiyoshi Inoue, Akihiko Shimizu

Patent number: 4750654Abstract: A backpack having a front panel normally riding on the back of the wearer according to this invention has a front panel which is vertically elongated and which is formed of an at least semirigid shell having a shape generally complementary to that of the back of the wearer and constucted to be relatively bendable longitudinally and relatively stiff transversely. Thus the panel can bend forward and back, that is about a horizontal axis, but cannot flex about a vertical axis. This is achieved by forming the shell with transverse rigidifying formations so it is longitudinally relatively bendable and transversely relatively stiff. These formations according to this invention are ridges or grooves.Type: GrantFiled: May 7, 1987Date of Patent: June 14, 1988Assignee: SACS Millet SAInventor: Marc Menetrier

Patent number: 4750312Abstract: An apparatus for fitting heat-sealed containers comprises a conveyor for displacing a succession of the containers in a normal direction of travel through a station and for arresting each of the containers momentarily in the station, a supply at the station holding a stack of caps, a grab for taking a cap off the stack and positioning it atop the container arrested in the station and a welding tool for tack welding the cap to the container in the station as the cap is being positioned on the container and while it is still held by the grab, and a device downstream of the station for heat shrinking the caps on the bottles. The welding tool and grab are practically the same device and work very closely together. Thus there is no time during which the cap is not being positively held. Before the grab releases it, it is tack-welded to the bottle.Type: GrantFiled: February 19, 1987Date of Patent: June 14, 1988Assignee: Manufacture Lyonnaise du BouchageInventor: Robert de Vaujany

Patent number: 4749920Abstract: A plurality of spindles of a textile machine are all mechanically interconnected and individually grouped, the individual groups of the spindles are driven by respective polyphase electric motors having respective feed lines all connected in parallel to the output lines of a polyphase electric power supply. Either the current or the voltage of the supply is maintained generally constant independent of load and a characteristic of the electricity in the feed lines of only one of the motors is monitored in the constant-current system or in the output lines of the supply in the constant-voltage system. An alarm, for example an optical or acoustic signal or just an indication on a display or printout, is generated when the characteristic of the electricity in any one of the monitored lines varies substantially from that of the other monitored lines.Type: GrantFiled: January 30, 1987Date of Patent: June 7, 1988Assignee: Zinser Textilmaschinen GmbHInventors: Wolfgang Jaeger, Dieter Werner, Claus-Peter Muller

Patent number: 4747417Abstract: A new composition is disclosed for the prevention of smoking which consists essentially of:(a) 2 to 4 parts/weight of a solution of silver acetate in distilled water or deionized water at a concentration of 1.5 to 7.5 g/l; and(b) 1 part/weight of a solution of ethanol of a pharmaceutical grade in which is dissolved an effective amount of a flavoring agent in the ethanol. Preferably, the composition is applied by spraying. The composition is made by a process which involves stirring of a mixture of water and the silver acetate for a prolonged period and combining the silver acetate solution with a solution of a flavoring agent in ethanol. When sprayed into the mouth, the resulting composition gives an unpleasant metallic taste discouraging smoking.Type: GrantFiled: September 10, 1985Date of Patent: May 31, 1988Assignee: Besco Laboratory Inc.Inventor: Michael D.

Patent number: 4748009Abstract: Process for the recovery of vanadium from vanadium-containing source materials under the addition of additives, especially alkali metal compounds, particularly the carbonates, chlorides, sulfates as well as nitrates and/or mixtures of these compounds, whereby the source material is ground and roasted. The roasted material is leached and whereby the withdrawn leach solution is hydrometallurgically treated for the recovery of vanadium compounds. The source materials are first roasted without the addition of alkali additives and subsequently are leached in a first leaching step. To the residues of the first leaching step are added alkali additives and the mixture is roasted in a second roasting step. The roasting products are again leached.Type: GrantFiled: October 2, 1986Date of Patent: May 31, 1988Assignee: GfE Gesellschaft fur Elektrometallurgie mbHInventors: Reinhard Hahn, Siegfried Sattelberger, Rudolf Fichte, Hans-Joachim Retelsdorf

Patent number: 4746922Abstract: This invention relates to a method of and a device for removing range ambiguity in a pulse Doppler radar and to a radar including such a device especially for missile guidance. On tracking operation at a high pulse repetition frequency the method consists in switching the repetition frequency f.sub.R (k) for each time interval .DELTA.t, over a new value f.sub.R (k+1) obtained in a circuit from the measured ambiguous range y(k) and from the ambiguity number n(k), as estimated in a circuit from radar information supplied by the radar, in order to remove eclipsing, to maintain the ambiguity number constant and to estimate the range with a growing accuracy in the course of the tracking operation.Type: GrantFiled: May 6, 1982Date of Patent: May 24, 1988Assignee: Thomson- CSFInventor: Michel Prenat

Patent number: 4746428Abstract: A filter wall constructed separtely from the frame member is clamped in a clamping slot, to which toward the outside edge of the filter plate a widened sealing slot in a shoulder of the support is connected. A projecting edge of the filter wall extends into the latter slot with the shoulder overlapping, the filter wall having an annular flange directed to the outside. The seal is arranged in the sealing slot and has a U-shaped cross section with two arms extending inwardly, whose arms enclose and seal both sides of the annular flange and which seals the support on one side and the frame member on the other side. The spacing between the seal and the joint is sufficient that upon release of the closing pressure of the filter press, without disengaging it, the frame can be moved sufficiently far from the support that the pressurizable chamber is unsealed at the seal in the sealing slot.Type: GrantFiled: November 5, 1986Date of Patent: May 24, 1988Assignee: Lenser Verwaltungs-GmbHInventors: Werner Junker, Franz Heckl

Patent number: 4744235Abstract: The rolls of a rolling mill can be axially moved by way of an actuator device equipped with piston-and-cylinder units. The bearing blocks which receive the journal ends of the rolls to be moved are horizontally guided in separate guide bodies. The guide bodies, in turn can be shifted vertically in cylinder blocks arranged at the flanks of the windows of the respective base member, or in pressure plates associated with such cylinder blocks. The actuator device is characterized by a compact design which even during exchange of rolls is contained in the confines of the roll stand, and it can be easily coupled to the rolls to be moved. The guide bodies of at least one base member are formed with lateral projections at which are mounted the motive power providing hydraulic cylinders, and these are connected in such a way that the piston rods thereof point in the direction of the guide bodies.Type: GrantFiled: August 14, 1986Date of Patent: May 17, 1988Assignee: SMS Schloemann-Siemag AktiengesellschaftInventor: Gunter Schiller
