Granted: 1991-05-09
Abstract: A railway vehicle control system comprises a railway track (1) and a plurality of transponders (N, N+1, N+2) at predetermined positions along the track. A railway track (2) moves along the track, the vehicle having means (20, 21) for detecting each of the transponders.

Title: Lubrication system for wide gearwheels - uses compressed air to spray lubricating fluid with spray nozzle moving along teeth
IPC: F16H57/04
Filed: 1971-01-19
Abstract: The particular feature of the design is that continuous lubrication is provided. The principle applications are in tube mills and the drive to revolving cylindrical furnaces. The spray nozzle moves to and fro along the whole length of the teeth. The drive of the spray nozzle causes the fluid to flow outward from the gear centre. The spray nozzle can be mounted on a pivot or can be fitted to two spindles with opposing threads to provide the reciprocating motion. There are limit switches to control end movement of the nozzle. The spindle drive is taken from the gearwheel end through a reduction gearing so that its traverse is fairly slow.

Title: Night-surveillance detector for heat-radiating targets - has mirror oscillated by leaf spring, moving coil and permanent magnet
IPC: H04N3/09
Filed: 1972-03-17
Abstract: An object which is warmer than its surroundings is detected using a heat-radiation-sensitive detector by alternately directing to the detector for the same periods of time radiation from an area including such an object and radiation from an adjacent surrounding area of the same size by means of a mirror mounted on the end of a leaf spring which is caused to oscillate by means of a moving coil cooperating with a permanent magnet, the coil being secured to the leaf spring or to the mirror. The amplitude of the resulting output signal from the detector is representative of the difference in the intensities from the areas and may be displayed on an oscilloscope. More than one detector may be employed so that a number of areas may be simultaneously monitored.

Title: Printing machine with a carriage locking and releasing device - has rack bars for the type wheels for selective rotation
IPC: B41L47/46
Filed: 1972-05-25
Abstract: Printing machine has type wheels rotatably arranged under the printing bed and partly exposed above the printing bed. Rack bars for the type wheels selectively rotate them. A carriage is mounted on the printing bed for travelling transversely between an initial nonprinting position and a second printing position. The carriage supports a roller platen for actually effecting printing. Locking means lock the carriage when it is in the initial nonprinting position and manual operating means release the locking means permanently or each time the printing operation starts so that the carriage may be moved for printing operations, whereby successive printing operations may be possible without having to operate the manual operating means; each operation. At the same time, careless reprinting can be avoided when the manual operating means is actuated for each printing operation.

Patent JP-S6035245-B2 (JP)
IPC: B29C45/27
Filed: 1982-01-29
Abstract: A production runner mold is disclosed which has a movable mold part (302; 402; 502) and a stationary mold part (303; 403; 503) defining a mold cavity (304; 404; 504). Opening on the mold to release a molded product defines a mold opening direction. The stationary mold part is separable into first and second sections (307; 407; 517; 308; 408; 518), the first section including a primary runner (310; 410; 509) and the second section including secondary runners (311; 411; 511). The secondary runners are inclined to the mold opening direction to improve the properties of the molded product. If for some reason the normal production cycle is terminated such that the molten plastic within the inclined secondary runners transfers additional heat to the walls of the inclined secondary runners whereby the molten plastic solidifies throughout its entire cross-sectional region, the normal production cycle may hereafter be re-established by the steps of: (h) separating the mold part which contains the inclined secondary runners into its two sections in order to expose the solidified impressions of the inclined secondary runners, (i) removing the solidified impressions of the inclined secondary runners in such a manner that the impressions of the restriction gate on the solidified impressions of the inclined secondary runners are removed through the inclined secondary runner in a direction which is not parallel to the mold opening direction; and (j) recombining the two sections of the mold part which contain the inclined secondary runners.

Patent JP-2909041-B2 (JP)
IPC: A61K6/90
Filed: 1997-02-24
Granted: 1999-06-23
Abstract: The present invention discloses high viscosity sustained release dental compositions, such as tooth bleaching or fluoride compositions, for treating tooth surfaces. For maximum results, an improved dental tray having reservoirs for holding the dental composition adjacent the desired tooth surfaces is preferably used in combination with the sustained release dental composition. The sustained release dental compositions include a high carboxypolymethylene concentration which results in very high viscosity. The high level of carboxypolymethylene makes dilution of the dental compositions from saliva difficult and time consuming so that the compositions stay within the tray reservoirs, thereby providing sustained release. The concentrated carboxypolymethylene adds a unique tackiness to the dental composition which helps retain and seal the soft tray material against the patient's teeth.
Patent JP-3224789-B2 (JP)
IPC: C08F4/619
Filed: 1999-03-04
Granted: 2001-11-05
Abstract: This invention uses a new method of producing ionic metallocene compounds. These compounds are useful as catalysts for polymerization of olefins, primarily propylene. This method uses an ionizing agent which ionizes the neutral metallocene compound. The ionizing ionic compound does not contain an active proton and contains a carbonium, oxonium or sulfonium cation. The anion of the ionizing ionic compound is not coordinated or is only loosely coordinated to the metallocene cation and is chemically unreactive with the metallocene cation. One such compound is triphenylcarbenium tetrakis(pentafluorophenyl)boronate. The process of making catalysts with this invention produces catalysts having high activity and does not produce by-products which can inhibit catalyst activity. This new synthesis is a clean reaction which does not produce a Lewis base. The process generates active catalysts by removing a methyl anion from a group IV metallocene derivative.
