Abstract: Two thyristors (A and B) have the emitter and base electrodes short-circuited on the anode side and on the cathode side respectively. The cathode of thyristor B is connected to the gate electrode of thyristor A and the two thyristors have their anodes connected together. Thus, a control signal applied to the gate electrode of thyristor B produces an amplified control signal which is applied to the gate electrode (4) of thyristor A which, in turn, controls the output of thyristor A at its cathode 3. Hence a small control signal can be used to control a large load current to reduce gate power losses. Also the thyr- lstor A is not turned off when the load current is less than a predetermined holding current. The thyristors A and B may be formed in one semiconductor substrate with the second and third layers of each thyristor formed in common.

Abstract: A cartridge for dispensing a fluent substance such as a mastic or an adhesive and which can be used either with a conventional gun or as a self-contained cartridge comprises an elongate container (1), a piston (7) movable longitudinally within the container for expelling substance through an outlet (5) at one end thereof, and a nut member (14) within the container between the piston and the other end of the container. A separate screw (20) cooperating between the nut member (14) and the piston (7) enables the cartridge to be used as a self-contained dispenser. To prevent the nut member (14) from being forced out of the other end of the cartridge, abutment means (19) are provided projecting inwardly of the container wall (1) at said other end. The abutment means (19) however project only as far as necessary to act as a stop for the nut member (14), and leave the other end of the container (1) substantially open and unobstructed so that the cartridge may be used in a conventional gun. In this latter mode the nut member (14) and the piston (7) move together as a unit longitudinally in the container (1) when dispensing substance.

IPC: G01F1/80
Filed: 1983-08-16
Abstract: A mass flow meter of the type in which movement of a loop section with the medium flowing through it produces a coriolis force in the latter which attempts to rotate the loop section around a swivel axis in proportion to the mass flow. The swivel axis is perpendicular to the axis around which the angular movement of the loop section takes place. In the known mass flow meters, the angular movement is a swinging movement. As a result of this, errors can be produced between the actual mass flow and the coriolis force resulting therefrom, and although they are in particular specific to the medium they also result from changes in the physical properties of a particular medium due to the operation. In the mass flow meter according to the invention these difficulties are avoided by not causing the loop section to swing but to rotate so that the coriolis force also always acts on the loop section in the same direction around the swivel axis, as a result of which any slip between the loop section and the medium flowing through it is eliminated from the outset. In the drawing, the rotating loop section is denoted by 1c, its rotary drive by 5 and the sensing device detecting deflections of the loop section under the coriolis force by 10 and 11. <IMAGE>

Abstract: The present invention relates to a polymer having a thiol group at one end of the molecule which is obtained by subjecting the monomers capable of radical polymerization to radical polymerization in the presence of a thiolcarboxylic acid and then treating the resulting polymer with an alkali or acid; to a process for producing the same; and to a block copolymer based on the polymer having a thiol group at the end. 
     The polymer having a thiol group at one end is difficult of forming disulfide linkages by oxidation and thus difficult of becoming insoluble. it is also a highly reactive material that will find wide use in varied application areas. The block copolymer based on the polymer having a thiol group at the end is superior in compatibility and will find wide use in varied application areas.
