Abstract: A drop-on-demand inkjet printing apparatus in which the print head has an ink cavity 22 which is filled with ink, and which has a nozzle orifice 26 designed so that ink does not flow out under static conditions. A fluid inlet chamber 28 is provided to receive ink from an ink supply pipe 24 and this chamber 28 is separated from the ink cavity 22 by a narrow gap 32. An electromechanical transducer 36 is mounted on a flexible plate 34 overlying the gap 32 between the ink cavity 22 and the inlet chamber 28. The transducer is selectively energized in response to the print data signals so that, when energized by an electrical signal, the transducer flexes the plate 34 to reduce the volume in the ink cavity 22 to eject one ink drop 19from the nozzle orifice 26 and substantiallyto close off the narrow gap 32 to substantially close the back flow path from the ink cavity 22 to the inlet chamber 28 during the formation of the drop of ink.

Abstract: in lining parts to be stamped of an aluminium electrolytic cell by filling a carbonaceous stamping material into the part and stamping the filled stamping material, a mixture consisting essentially of a carbon aggregate and a binder and being capable of being stamped at a temperature above 100° C is prepared; a solvent for the binder containing aromatic hydrocarbon as a main component in an amount incapable of effecting stamping of the stamping material at room temperature, but capable of stamping at a temperature of 50 to 100°C, when added to the mixture, is prepared separately from the mixture; the mixture and the solvent are mixed together to prepare a carbonaceous stamping material; and the carbonaceous stamping material is applied to the part to be stamped of the cell at a temperature of 50 to 100° C to effect the lining of the cell. The stamping environment is greatly improved by eliminating generation of pitch fumes and hot vapors and at the same time deterioration in physical properties of the stamping material is substantially prevented.

Abstract: A digital speed control system for a sewing machine comprises a digital speed setting device (5) which responds to manual depression of a foot pedal by generating a digital position signal. A variable frequency divider (4) divides the frequency of speed related pulses so that its output frequency is an integral submultiple of the input frequency, which is variable as a function of the digital position signal. A period detector (6) senses the interval between pulses that occur successively at the output of the frequency divider and generates a binary data representing the sensed interval. The interval representing data is translated into a second period data in an arithmetic unit (8') according to a predetermined transfer function. The arithmetic unit provides correction of the most recently sensed pulse interval according to the direction and amount of the deviation of the most recent pulse interval with respect to the preceding pulse interval, whereby the second period data is accordingly modified by an amount proportional to the rate of sewing speed variation. A pulse generator (9) translates the second period data into a pulse for activating a magnetic clutch or a magnetic brake depending on a sign of the second period data to accelerate or decelerate the sewing machine.

Abstract: An angular vibration isolating mechanism (10) is provided for a vehicle seat comprising a seat frame (16), a seat cushion (14) and a seat back (12), and this mechanism may be combined with a mechanism for adjusting the angle of the seat bapk. Eccentrically mounted cylindrically shaped cams (38) located at each side of the seat back (12) can be adjustably rotated around a shaft (32) within a guide channel (28) carried by the seat back (12). The cams (38) are positioned at a distance from a pivot axis (22) on the seat frame (16) around which the seat back (12) can tilt in order to adjust the angle of tilt. The flange (42) of each of the guide channels (28) is spaced from its respective cam (38) by a resilient means such as a thick pad (41) of elastomeric material which fills the space between the cam and the flange. The elastomeric pads (41) are compressed as the seat back (12) is forced forwardly against the seat occupant's back due to vehicle vibration, thus permitting the seat back to be driven rearwardly while the occupant's position in space remains relatively fixed.

Abstract: A rotary external combustion engine wherein energy is transferred to air acting as a working gas by injection into the air of liquid water at a high temperature and pressure. The liquid water is injected either directly into the working space in the stator or into a preliminary mixing chamber. The water acts as a heat-transfer medium for heating the air. Spontaneous vaporization of the liquid water on injection increases the pressure of the air which drives the rotor before being exhausted. The exhaust water is recovered and recycled. The working space is scavenged and refilled with a fresh charge of air.

Abstract: The operator of a taphole drilling apparatus for blast furnaces performs manual changes on the apparatus in its safe position of rest and operation by remote control and automatic latching in hazardous taphole work including drilling and subsequent driving, release, and extraction of a tap bar. The usual guide rail (22) carrying reciprocably a hammer drill (30) thereon incorporates a remotely openable automatically latching centralizer (42) at its forward end and an extraction carriage (29) on which, after removal of the drill steel (43), an impact sleeve (50) can be manually mounted for being impacted by the hammer drill (30). In one mounting position (FIG. 5) of the impact sleeve (50), a latch (57) therein is biased to automatically latch the shank of a tap bar (53) thereto for extraction by impacts. In a 180 DEG  counter-turned position the latch (57) will fall aside and the mounted sleeve (50) is used to drive the tap bar while guided by the centralizer (42). The sleeve (50) can then be retracted freely from the tap bar (53) and the guide rail (22) freed by unlatching the centralizer (42) from the tap bar (53).

Abstract: A synchronization voltage is formed as the product of the output voltage of a phase-locked loop and the mean value of the magnitude of the network voltage. The synchronization voltage is compared with the network voltage. A first control signal is formed when both voltages are the same. A reversing switch, in a first switching state, conducts the network voltage and, in a second switching state, conducts the synchronization voltage to a reference frequency-input of the phase-locked loop. A second control signal is formed when the phase-locked loop locks or latches with the thereto inputted reference frequency. The reversing switch is controlled by both control signals such that upon absence of the first control signal and the simultaneous presence of the second control signal there is attained the second switching state and otherwise the first switching state. The circuit can be beneficially used in a current regulation circuit of a drive for a powerful electric motor, with a power supply network operating at up to 400 Hz with a weak generator.

Abstract: In the method according to the invention at least one inductance is produced which varies with depth of penetration of the core rod. With the aid of this inductance, a measurable, temperature-independent voltage signal and/or frequency signal is produced which is proportional to the instantaneous position of the core rod. To carry out the method, an apparatus is used which has at least one measuring coil (1) and at least one component (2) which varies the inductance of the measuring coil (1) as a function of the depth of penetration of the core rod. For the purpose of measuring the depth of penetration, the measuring coil(1) is connected to an evaluation circuit (4), which is additionally connected to a sensor (3) which detects the influence of the temperature on the inductance of the measuring coil (1) and tunes the evaluation circuit (4) thereto. <IMAGE>

Abstract: Particle-laden gas passes downwardly through an inlet duct into inlets of several wedge-shaped deceleration chambers formed by vertical plates radiating from a central region below the bottom of the inlet duct. The inner ends of the plates and the inlets of the chambers are vertically below the bottom of the inlet duct. In each chamber the gas first proceeds towards a particle exit at the bottom of the chamber, then reverses direction and passes upwardly into filter units above wider parts of the chamber, depositing some heavy particles near the particle exit. To purge the chambers and filter units, suction means are connected to an outlet duct and one or more inlets to the chambers are closed off from the inlet duct simultaneously with the particle outlet(s) of the same chamber(s) being opened to said outlet duct.
