Abstract: The invention relates to an assembly for dispensing at least one fluid product; this assembly comprises at least one dispensing channel 8c, each channel comprising at its end part a closure system opening to the exterior. The closure system is formed by a sealing device (9a) which is part of a piece made from elastically deformable material and a seat 8e which is part of another piece of the dispensing head (3), the sealing device (9a) being in contact with its associated seat (8e) when there is no dispensing, moving away from the seat due to elastic deformation under the pressure of the product to be dispensed and returning due to elasticity in contact with the said seat (8e) when dispensing ceases. The sealing device is subject to the action of a stressing member (11) which tends to keep it pressed on the seat (8e) with which it interacts.

Abstract: Ultrasound is used to determine the degree of adherence between an explosive (4) and a delimiting surface of a delimiting wall (2, 3). The measurements are carried out in two different runs, on the one hand in the form of a preparatory measurement run in which the explosive has not yet been applied against the delimiting surface and, on the other hand, in the form of a main measurement run in which the explosive has been applied. In the measure­ment run without explosive, the delimiting surface may if appropriate have been provided with a lacquer layer (5) designed to increase the adherence of the explosive. In both measurement runs, two different measurement series are carried out. The ultrasound is directed towards either the inner surface of the delimiting wall or its outer surface. Reflected ultrasonic signals are received and recorded. Ratios between related inner surface echoes and outer surface echoes are calculated, and the dif­ference between the ratios for the preparatory measure­ment run and the main measurement run represents a very good measurement of the degree of adherence.

Abstract: In a charge device having a storage cell terminal (11) to be connected to a storage cell (12) to be charged, a trickle charge terminal (13) for receiving a trickle charge voltage, and a boost charge terminal (14) connected to the storage cell terminal for receiving a boost charge voltage and including a constant current circuit (16) for causing a constant current to flow from the trickle charge terminal to the storage cell terminal, a boost charge detector detects the boost charge voltage to produce a boost charge signal when the boost charge terminal is supplied with the boost charge voltage. An interrupting circuit interrupts the constant current when the boost charge detector circuit produces the boost charge signal. The constant current circuit may comprise a transistor (161) having a base electrode supplied with the trickle charge voltage to produce the constant current. In this event, the interrupting circuit is a conductor (191) connected between the boost charge detector and the base electrode of the transistor (161).

Abstract: A circuit for correcting raster distortion on a CRT display screen. Horizontal distortion is corrected by overscanning and providing complementary modification of the time delay and data rate at which digital video data is supplied to the CRT during each scanning line. The video data for a given scanning line is stored in a line store, read-out therefrom being controlled by a microprocessor programmed to determine the necessary time delay and data rate of such read-out. Vertical distortion, affecting scanning lines in the vicinity of the top and bottom of the raster, is corrected by storing in a multiline store the video data for all such scanning lines. The same or a further microprocessor is programmed to re-assign the video data for pixels on each of such lines to vertically corresponding pixels on others of the scanning lines, such re-assignments being complementary to the vertical distortion of the original scanning lines.

Abstract: A rapid start fluorescent lamp (10) having an improved hot restarting time. The lamp (10) includes the standard envelope (12) and end cap (14) through which electrical connection is made by conductive feedthroughs (18,20) which extend through the lamp stem (16) to the interior of the lamp. One of the feedthroughs (20) is connected to the cathode (22), and the other is connected to the leads (28,30) of a fuse element (32) which is contained within an envelope to isolate the fusible element (32) from the lamp environment. A thermally activated bimetallic element (46) is disposed across the leads (28,30) of the fuse (24). The other lead (30) of the fusible element (32) is connected to the other end of the cathode (40). When the bimetal element (46) is cold, it will bridge the connection between the other feedthrough (18) to the other end of the cathode (22) to permit rapid starting. When the bimetal (46) heats up, the connection of both ends of the cathode (22) to the heating current is broken. The location of the bimetallic element (46) within the lamp (10) envelope (12) but not in the fuse (24) container permits it to open and close more rapidly. Additionally the fuse assembly (24) is utilized as part of the supporting structure for the filament (22) assembly.

Since the process of forming the tab region of the power transistor is followed by the process of introducing impurities into the channel region of the small signal transistor, the threshold voltage of the small signal transistor is not influence by the process of forming the tab region of the power transistor.

Abstract: A cam gear controlling mechanism which is simple in structure, small in overall size and high in reliability of operation. The controlling mechanism comprises a cam gear having toothed and non-tooted portions and a cam groove, a trigger lever having a projection fitted in the cam groove and movable between arresting and non-arresting positions, a spring biasing the trigger lever to the non-arresting position, and electromagnetic means for releasably holding the trigger lever at the arresting position. When the cam gear is engaged with a driving gear, it is rotated in one direction by the latter, but when the driving driving gear is opposed to the non-toothed portion, a stopper projection on the cam gear is abutted with the engaging projection to lock the cam gear there. When the trigger lever is released from the electromagnetic means, it is moved to the non-arresting position to release the cam gear while the projection operates the cam groove to rotate the cam gear into engagement with the driving gear, and then, the cam groove operates the projection to return the trigger lever to the arresting position.

Abstract: A system and method for storage and retrieval of both time-oriented versions and view-oriented versions of engineering change information in which the engineering change information progresses through a set of status conditions and access to the data by different user groups is conditioned upon the status of the information. Version control software logic enables users to create versioned objects by logical key grouping of data elements. The version control logic acts upon the logical keys and special versioned attributes of these objects for the proper specification and selection of object instances during creation, update or retrieval processing. Insert and extract sequence numbers are automatically generated for both historical preservation of previous engineering change information and efficient retrieval of the currently effective designs. Instance level security facilitates the merger of different versions of the engineering change data having different engineering change status levels so that similar types of data can be contained within a single data base table.
