Abstract: The present invention relates to a novel method for forming metal matrix composite bodies and the novel products produced therefrom. A negative shape or cavity, which is complementary to the desired metal matrix composite body to be produced, is first formed. The formed cavity is thereafter filled with a permeable mass of filler material (7). Molten matrix metal (8) is then induced to spontaneously infiltrate the filled cavity. Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are also in communication with the filler material (7), at least at some point during the process, which permits the matrix metal (8) when made molten, to spontaneously infiltrate the permeable mass of filler material (7), which at some point during the processing, may become self-supporting. In a preferred embodiment, cavities can be produced by a process which is similar to the so-called lost-wax process.

Title: Hydrogenation of substrate and products manufactured according to the process
Inventor: HARROED MAGNUS
IPC: C07B61/00
Filed: 1997-10-27
Abstract: A typical traditional reactor for hydrogenation consists of a tank filled with a liquid and a gas and a small particle catalyst. The reaction is carried out at high pressures and high temperatures. Lack of gas on the catalyst surface limits the velocity of reaction. Much work has been done to increase the quantity of gas on the catalyst. It has not been possible to solve this problem effectively with the techniques of today. According to the invention an extra solvent is added to the reaction mixture. By bringing the whole mixture (solvent, substrate, hydrogen and reaction products) to super-critical or near-critical state, a substantially homogeneous mixture can be obtained. By this method it is possible to control the concentration of gas on the catalyst to the desired level. The velocity of reaction is thereby increased considerably. The hydrogenation reactions principally involved comprise hydrogenation of carbon-carbon double bonds (C=C) in lipids; hydrogenation of COOR to C-OH and HO-R to produce fatty alcohols; and direct hydrogenation of oxygen to hydrogen peroxide.

Patent PT-82218-B (PT)
IPC: H02P1/00
Filed: 1986-03-18
Abstract: A motor current demodulator is coupled to the stator winding to monitor operating efficiency-related parameters of the surge current each time the current in the stator winding increases from zero. The demodulator generates an output control signal whose magnitude is dependent upon the efficiency-related surge current parameters. A control circuit responds to this output control signal to regulate theenergisation from the power supply by varying the portion of each sine wave which is coupled to the stator winding. The control circuit is deactivated during the start mode. As the motor approaches synchronous speed the control circuit is rendered operative to switch the power control system from the start to a run mode. (Provisional Basic advised week 85/49).

Title: Method of machining a lengthwise weld in a pipe and arrangement for carrying out the method
Inventor: LARSSON B H
IPC: B21C37/08
Filed: 1980-03-17
Abstract: When machining a lengthwise running weld 24 in a pipe, 10 inches, which is formed by bringing together and welding the lengthwise edges of a bandlike workpiece, the pipe weld is subjected in stages and under local deformation of the cross section of the pipe to a rolling between a rolling tool 19 which can be placed against the weld from the outside of the pipe and an elongated mandrel 20, introduced into the pipe, which during the welding bears against a portion of the pipe wall opposite the weld from a retaining element 18 co-operating with the outside of the pipe, wherein the rolling of the weld occurs under a relative motion in the lengthwise direction of the pipe between the pipe with the mandrel secured therein by the roll pressure, on the one hand, and the rolling tool, on the other. In order for the mandrel to be able to have a shorter length than the pipe when using this welding processing technique, after accomplishment of each rolling stage and for a period of time when the roll pressure is made to cease it is necessary to move it in its lengthwise direction to a new working position in the pipe. Thus far, this has been done by pulling the mandrel inside the pipe, which has caused inconveniences that are eliminated according to the invention in that the end portions of the mandrel are provided with running rollers 26 allowing the mandrel to move under rolling contact with the inside of the pipe. <IMAGE>

The aperture has a pivotable hatch cover (1) which opens automatically under the effect of a specific excess pressure in the building. The hatch cover (1) has an automatically acting stop arrangement (10) which normally locks the hatch in the closed position. On the hatch or connected to it is a release unit (6) which when the specific excess pressure is present moves the stop mechanism downwards from its locked position. The stop mechanism (10) comprises at least one hook rotatably attached to the hatch and activated by a spring (11), and in its locked position grips the edge (13) of a frame (3) around the pressure discharge aperture.

Inventor: VAN DER HAVE L A
IPC: G01L19/04
Filed: 1982-03-31
Abstract: The transducer system includes a reluctance resistance bridge having coils on E cores for measuring the pressure differential across a sensor element such as a diaphragm. This bridge is activated by a signal generator and normally its output would be independent of the sensor temperature. The A.C. output of the signal generator is modified such that the temperature compensation is made in the transducer activator or excitation and not in subsequently modifying the transducer output signal. A voltage source pref. in the range of 5 to 10 volt provides the reference voltage to Vc corresponding to the reference output of the current source at the calibration temp. - One branch of the Norton divider is a variable conductance ladder having an output current which increases at a programmed rate as the current from the temp. dependent source increases. The operational amplifier provides the output of the compensation circuit and the temp. dependence of the output voltage is a close approximation to the inverse of the temp. dependence of the sensors or transducers.

Title: Catching apparatus for lifts
Inventor: ERIKSSON R
IPC: B66B11/04
Filed: 1982-10-14
Abstract: A catching apparatus for lifts, in particular lifts carried by toothed racks, at which a centrifugal regulator, having a shaft 2 rotating by means of a coupling 4 to the movement of the lift, is arranged in connection with a brake with a stationary brake part 6 and a movable brake part 8 cooperating therewith. The movable brake part is rotatable and is displaced towards and away from the stationary brake part, and is in a normal condition declutched from said shaft 2, and is thereby forced by a spring 16 in a direction towards the stationary brake part 6. The centrifugal regulator is at triggering arranged to clutch said shaft 2 to the rotatable brake part 8 for forcing this into rotation, and to a clamping device 22 for the spring 16 which is adapted to actuate the spring to press the movable brake part successively more intensely against the stationary brake part, due to the rotation of the regulator shaft. A pressure-relieving device 30 has the function of displacing, when needed, the movable brake part 8 for at least lightening the abutment of the movable brake part 8 against the stationary brake part 6 in the normal condition, against the functioning of the spring 16. The pressure-relieving device is thereby arranged such that a declutching action be initiated with said functioning being cancelled. <IMAGE>
