Abstract: The invention relates to a process for the preparation of 1-alkyl-5-aroyl-1H-pyrrole-2-acetic acid. derivatives of the general formula (I) < IMG > (I) wherein Ar is phenyl optionally substituted with halogen, alkyl having one to 4 carbon atoms or alkoxy having one to 4 carbon atoms; R is alkyl having one to 4 carbon atoms; R1 is hydrogen or alkyl having one to 4 carbon atoms; X is an imino group and R2 is hydrogen or an alkyl group having one to 4 carbon atoms, or X is oxygen and R2 is hydrogen, and acid addition salts (if X=imino) and alkali metal or alkali earth metal salts (if R2=H) thereof, The above compounds are prepared. by reacting a pyrrole derivative of the general formula (II) < IMG > (II) wherein Y stands for a -COOR3 group and. R3 is an alkyl group having one to 4 carbon atoms, with an aromatic nitrile of the general formula Ar-CN wherein Ar is as defined above, in an organic solvent, preferably aromatic hydrocarbon, saturated with dry hydrochloric acid gas and, if desired, hydrolysing a ketimino ester obtained into a corresponding ketimino acid or keto acid or a salt thereof. The process affords the desired products with a good yield, selectively, and, if desired, can be carried out in one pot, without isolating the intermediates.

Abstract: CONTINUOUS CASTING PROCESS AND APPARATUS In a continuous casting process the flow, of molten metal is continuously fed into a mould to be further submitted to the action of the magnetic field generated by an electrical inductor and to that of a stabilizing coil so that a column of molten metal is formed. The column of molten metal is then cooled to produce a continuous strand or ingot. The current supplied to the stabilizing coil has its phase lagging behind that of the current in the inductor with the phase angle between them ranging from 95.degree. to 165.degree.; the amplitude of current in the stabilizing coil being 0.1 to 0.4 time the current amplitude in the inductor. Apparatus for performing the above-described continuous casting process comprises a mould formed by an electromagnetic inductor and a stabilizing coil from a nonmagnetic material in the form of triangle arranged coaxially with the inductor and having its apex oriented inside the mould. The height of triangle in cross-section of the stabilizing coil and the greater side of the triangle are in the ratio ranging from 0.7 to 0.96.

Abstract: A pressure roll for use in a calender has a beam whose end portions are mounted in a stationary frame and which is spacedly surrounded by a hollow cylindrical shell. Groups of hydrostatic supporting elements are installed in the space between the shell and the beam, and each such group has several supporting elements, as considered in the circumferential direction of the shell. Each supporting element has several hydraulic pressure transmitting cylinder and piston units which are adjacent to each other, as considered in the circumferential direction of the shell. The axis of the shell is held in a supporting plane which includes the axis of the pressure roll as well as the axis of an adjacent roll, and such retention of the axis of the shell in the supporting plane is effected exclusively by regulating the pressure of hydraulic fluid in selected pressure transmitting units. The end portions of the shell are movable radially of the respective portions of the beam.

Abstract: A slide sheet has a friction part 1, which is made of friction material (the coefficient of friction is approximately the same as for a normal sheet material) and a sliding part 2, which is made of a material with a low coefficient of friction and is situated under the centre of the patient when the latter is lying on their back on the bed. When the slide sheet is arranged on the bed, an area of the friction part 1 with a width of 5 to 15 cm is left along each of the edges of the bed and on both sides of the slide part. These areas of the friction part prevent the patient from slipping down off the bed, and where required the patient can also achieve a supporting grip with the hands in order, for example, to turn over on the bed or to raise himself or herself up from the bed. The object of the slide sheet is to facilitate handling on the bed of patients in a weak condition or with impaired capacity for movement. When the slide part 2 is under the centre of gravity of the patient it is easier to turn the patient on the bed and to raise the patient from the bed than with the use of a normal sheet. <IMAGE>

Abstract: The motor saw has a rear handle connected to the body by vibration-damping elements with rubber or steel springs, and the throttle of the carburetor and the throttle control are connected by a rigid wire link. The throttle control bearing includes a shaft mounted in oblong holes to give a longitudinal play so that when the handle is moved with respect to the body, the throttle control can move the corresponding distance in the bearing without influencing the setting of the throttle in the carburetor in its idle position. When the handle is moved in this position, and a throttle opening is desired by moving the throttle control, a sliding part at the rear end of the throttle will contact a curved partition in the handle and push the throttle control to an advanced position, after which an opening of the throttle takes place by further movement of the throttle control.

Abstract: A turbine blade for a gas turbine engine has internal passages which are opened at their roots to supply pressure so that there is a constant flow of cooling air inside the blade in use. The blade has an airfoil surface and a number of internal passages inside the walls of the blade, some being formed adjacent the mid-chord section and extend from the root section to the tip section to define feed channels open at the blade root section. A number of radially spaced film cooling holes in the airfoil surface communicate with each feed channel to flow a film of cooling air adjacent the airfoil surface. A number of replenishment holes are radially spaced in the wall to flow air from the mid-chord section to the feed channel(s) to replenish the cooling air in the feed channel(s) that is otherwise lost in supplying air to the film cooling holes. A device communicates cooling air from the root section via the feed channels to discharge from orifices in the airfoil surface at the tip section.

Abstract: A multiphase stepping transformer wherein a closed vacuum interrupter at each phase is opened before a respective stepping switch is advanced is controlled by continuously monitoring current flow through the interrupters. Before the interrupters are opened an error signal is generated unless all of the monitored current flows lie to one side of a predetermined threshold. After the interrupters are opened an error signal is generated if current flow is detected through any of the interrupters. Advance of the stepping switches is blocked on generation of any error signal. The apparatus includes for each interrupter a respective current detector, a light-emitting diode energized by the respective detector, a light receiver associated with each diode, and a light-transmitting cable connecting each diode with the respective receiver.
