This bar is movable from a position locking the cylinder, in which position it is located partly in a groove in the internal wall of the cylinder housing, to a position releasing the cylinder by entering a channel formed jointly by notches in the peripheral edges of the tumbler discs when the discs are turned to a certain position. The movement of the locking bar is laterally guided by means of guiding discs, at least substantially non-rotatably fitted with respect to the cylinder.

Abstract: A hollow blank, such as a tube, is inserted in between two dies and is also received by two retractable die members. The interior of the blank is closed off, but working fluid is admitted to widen the blank. Widening is at first restricted to a central portion established by conical front faces of the die members. These members are retracted while continued application of fluid pressure progressively widens the blank, urging blank material into continued abutment with the front faces of the receding die members.

Abstract: The invention relates to a method and apparatus for the manufacture of a screw-line shaped reinforcement spiral out of metal wire for the reinforcement of concrete pipes or columns. The wire is, while subject to tensile stress, wound onto a cylindrical last whose diameter is equal to the inner diameter of the spiral. The wire, before coming onto the last, passes over a roll that prestresses the wire to a curve of such a small diameter that, after the wire has been taken off the curve, a tension tending to bend the wire in the direction of bending of the reinforcement spiral remains in the wire. The winding takes place so that at the immediate proximity of the initial end of the last the wire passes over rolls. The first roll, whose projection is partly outside the projection of the mantle of the last and which gives the wire a curve radius smaller than the radius of the last, makes a tension bending in the wire in the direction of bending of the reinforcement spiral which bended remain in the wire.

Abstract: Forging of a camshaft which is formed integrally with plane cams arranged longitudinally thereof. A blank for the camshaft has its cam-forming portion heated to different temperatures with the heating temperature decreasing from the axially central position towards the opposite ends.

Abstract: An internal combustion engine self-testing control system has a microcomputer, which includes a memory unit pre-programmed with a program for testing the microcomputer. The system is so programmed as to be able to test itself by using an indicator to show the system state before controlling actuators that affect the engine operating values. That is, since it is impossible to test the system merely by observing the indicator states produced by the system, one or more test processes are added before controlling the actual engine operating values. In one example, the test timing is controlled by a power signal generated when the power supply is turned on, a start signal is generated when a starting switch is turned on (while the engine is being cranked), and a revolution indicating signal is generated when the engine is rotating.

Abstract: The interior space of a combustion chamber, boiler, or other such gas-filled chamber exhibits an acoustic response spectrum to acoustic energy excitation which includes plural maxima attributable to acoustic natural-vibration frequencies. The frequencies of these natural vibrations are dependent upon both the interior temperature of the chamber and also upon the normality or molarity of the gaseous contents of the chamber. One of these two variables, i.e., temperatures or else normality or molarity, is measured by conventional devices. The other variable is then measured using a pressure transducer generating an electrical signal indicative of the chamber interior's acoustic response spectrum, the transducer output signal being applied to a discriminator circuit which develops a measurement signal indicative of the value of the variable being measured. In this way, interior temperature can be continuously monitored by acoustic devices with high accuracy.

Abstract: A ring of transmitter and receiver transducer arrays circumscribes an object to be scanned. Semicircular wave fronts of ultrasound energy are propagated from different points around the ring of transducers by triggering the transmitter arrays in sequence. The reflected and transmitted ultrasound energy picked up by the receiver arrays is then electronically analyzed and a synthetically focused image corresponding to the scanned object is reconstructed on a display screen. Surprisingly high quality resolution for the reconstructed images is achieved by carefully controlling the type of waveform from which the displayed image is reconstructed. In one embodiment of the invention, the signals received by the receiver arrays are processed by a waveshaping circuit to achieve the desired waveform. In a second embodiment of the invention, the desired waveform is generated by a waveform generator circuit and transmitted by the transmitter arrays.

Abstract: An improvement in torsional vibration monitors wherein a frequency shift is applied to the torsional vibration signal to achieve improved stability and increased confidence in the measurement. The torsional vibration signal is applied to parallel frequency shifters to produce a lower frequency measuring signal and a lower frequency reference signal. The two lower frequency signals are applied to parallel connected filters to obtain spectral content of the signals. Once the spectral content is obtained, each lower frequency measuring signal and each lower frequency reference signal is shifted back to the original frequency range to produce filtered reference signals and filtered measuring signals. These signals are then correspondingly summed to provide a set of torsional vibration signals segregated with respect to the frequency spectrum and meaningful with respect to a time base.
