Patent EP-0445091-A1 (EP)
Inventor: HYVAERINEN PENTTI
IPC: A61C17/00
Filed: 1991-01-23
Abstract: Closing mechanism (40) for the suction device used in connection with a dentist's treatment machine, said mechanism being connected to the suction hose ( 14) of the suction pump. The mechanism (40) comprises a valve device by whose means the air flow (S) can be switched on to act upon the suction nozzle (30) of the mechanism (40). By means of the suction nozzle (30), liquids and solid particles (SP) are sucked out of the patient's mouth. The closing mechanism is placed on support of an opening (10a) or slot in its holder ( 10) when the suction device is not in use. The closing mechanism (40) comprises parts (41,43, 46,50,51) permanently fixed to the suction hose (14) and parts (42,44,45) that can move in relation to said fixed parts. A spring (48) or springs is/are fitted between said mobile and fixed parts, said spring/springs keeping the closing mechanism (40) in a stable open position (Fig. 3A) when the closing mechanism is outside its holder (10). When the closing mechanism (40) is allowed to rest on support of its holder (10), the mobile parts (42,44,45) in the mechanism, being supported by a shoulder (10b) or equivalent in the holder, are displaced in relation to the fixed parts (41,43,46,50,53) of the mechanism, and a valve disk (40) or an equivalent closing piece, placed between the mobile and the fixed parts, closes the valve substantially by the effect of the weight of the suction hose (14) and of the fixed parts against the spring force (Fig. 3B).

Title: Stock dividing method and apparatus for gear manufacturing machines.
Inventor: LOEHRKE JOHN M
IPC: G05B19/404
Filed: 1991-04-24
Abstract: Method and apparatus for stock dividing gear-shaped workpieces mounted on the work spindle of a gear-finishing tool. A work spindle encoder provides instantaneous angular position information when the surface of leading and trailing flanks of the workpiece teeth are sensed by a probe. This instantaneous position information is used to generate two sets of measured error values which relate, respectively, to the leading and trailing flanks and which are indicative of the differences between the sensed surrfaces and the desired surfaces of a correctly-sized gear. These sets of error values are analyzed using fourier transform techniques to generate (a) a first harmonic for each set and (b) a set of modified error values for each leading and trailing flank corresponding to each respective first harmonic. The largest and smallest modified error values of each set are used to simulate the opposite sides of the largest and smallest "effective" (as different from "actual") tooth spaces of the unfinished workpiece, and these effective spacings are compared to the desired correctly-sized tooth space of a finished gear to generate a correction value for adjusting the angular position of the workpiece relative to the finishing tool prior to initiation of the finishing process. In the preferred embodiment, a non-contact probe is used for sensing the flanks of the workpiece so that the entire stock division procedure takes only a relatively few seconds.

Abstract: An optical identification label (3) consisting of an area of hologram (10) or diffraction grating which is transparent to visible light but reflects incident light with a specific reflective directivity. By identifying the reflectivity directivity, it is possible to identify the authenticity of the label (3) and, hence the object to which the identification label is affixed. The fact that the identification label (3) is transparent to human eyes offers a strong discouraging effect on potential forgers. Further, the pattern of the reflected light may be used for encoding data.

Abstract: A synchro system which consists of a rotationally positionable cylindrical permanent magnet 12 with a magnet axis extending perpendicularly to the axis of rotation of the permanent magnet and of two Hall elements 18, 20, offset with respect to one another with their measuring axes A, B in the circumferential direction of the axis of rotation, for generating measurement signals in each case changing sinusoidally in dependence on the rotational position of the permanent magnet and displaced with respect to one another by a predetermined phase angle of 90 DEG , is characterised, having regard to a simple inexpensive and extremely space-saving type of construction, in that the Hall elements are permanently mounted on a common integral sensor carrier 4, 26 and the permanent magnet is arranged adjustable in height with respect to the Hall elements for calibrating the 90 DEG  phase shift in the direction of the rotational axis of the permanent magnet. Furthermore, the mutual angle of attack  alpha  of the two measuring axes A, B is preselected independently of the required phase angle, having regard to further space saving, and the angular difference between the angle of attack and the predetermined phase angle is compensated for by the fact that the measuring axes are in each case aligned eccentrically with respect to the rotational axis of the permanent magnet at a corresponding distance e. <IMAGE>

Abstract: Apparatus for developing a series of square-wave pulses (112) from an alternating voltage (110) generated in the pick-up coil (20) of a variable reluctance sensor (16-20) associated with a slotted wheel (10) driven by the crankshaft of an internal combustion engine (12). The system has an adaptive control which comprises a peak detector (52-58) including a capacitor (56) and a voltage comparator (Q1-Q7). The capacitor (56) is charged to a peak voltage that corresponds to the peak value of the positive half-cycles (110A) of the alternating voltage (110). The comparator (Q1-Q7) is connected to compare the peak voltage and a voltage that corresponds to the magnitude of the positive half-cycles. A diode (44) is connected between the pick-up coil (20) and the peak detector (52-58) which prevents charging of the capacitor (56) and accordingly prevents adaptive control until the voltage induced in the pick-up coil (20) is high enough to cause the diode (44) to conduct in the forward direction.
