Patent MX-169367-B (MX)
Inventor: MOKRY PATRICIA A
IPC: G11B5/596
Filed: 1988-10-11
Abstract: A magnetic data storage system for use with a double sided disk in which a prerecorded pattern of opaque optical lines is used to define the tracks in which magnetic data is to be stored. A separate optical system including an illumination source and a photosensitive detector is provided on a read/write assembly for each side of the disk. Each detector is designed also to serve as a reference grating. The illumination source is designed to image the prerecorded pattern of optical lines on the reference grating as an indication of the alignment of the read/write head of the assembly and a desired data track and any misalignment of the head and track generates a servo signal. The detector uses four separate photocells interleaved in a prescribed fashion to form a quadrature detector that is adjustable to compensate for various non-uniformities. One form of illumination source uses a surface-emitting light emitting diode and optics for forming a multiple beam source.

Abstract: 983,450. Inverting. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Sept. 20, 1962 [Sept. 28, 1961], No. 34891/61. Heading H2F. [Also in Division H3] In an alternating current supply circuit including an inverter with two switching elements through which a direct current source is connected, in opposite senses alternately to a load, the on/off ratio of the two switching elements is varied at a frequency lower than the inverter frequency, so that the output voltage is pulse width modulated at the lower frequency (Fig. 2b). The output of the power supply circuit is at this lower frequency, and the high frequency component is filtered out. In Fig. 1, the inverter comprises controlled rectifiers 1 and 2, transformer 7 and commutating capacitor 8. The multivibrator including transistors 21, 22 drives the inverter at a frequency at least several times the desired final output frequency. A sinusoidal bias voltage (of the desired final output frequency) is applied at 29 and this alters the relative conducting periods of the two sides of the multivibrator, and hence of the controlled rectifiers 1, 2. Without the varying bias the inverter output voltage would be as shown in Fig. 2a, but with the varying bias it is as shown in Fig. 2b. The filter networks 11, 12, 13 and 14 allow only the low frequency component to reach the output terminals 10. In another embodiment (Fig. 5) the multivibrator is replaced by a bi-stable circuit which is switched by the error voltage derived by connecting in series opposition a reference voltage 47 and a portion of the output voltage. The inverter frequency is determined by the speed of response of the control system, and the output voltage follows the reference in both magnitude and phase. A three-phase embodiment is described (Fig. 6, not shown). Figs. 3 and 4 of the Provisional Specification are a block diagram of the embodiment of Fig. 5 of the Complete Specification, and a circuit similar to that of Fig. 6.

Filed: 1981-12-30
Abstract: This invention is a device for positioning a machine element (69) in a clamping tool (1) initiating from at least one gear profile (56) of the machine element (69). A similar device is preferably designed for centring a gear wheel (69) in a chuck (1) for a work machine, such as a grinder.The invention is distinguished primarily bythe device containing a number of ball races (64, 65) that are opposite each other in pairs following the axial direction of the tool (1). The end faces of these races have axial cavities that constitute the seats for balls (67) situated between the ball races (64, 65) with a certain clearance andthe balls (67) being designed to during positioning engage in the gear profile's tooth gaps (70) and be brought to lie against the gears (56) in the gear profile by the forces of the tool (1) with its clamping jaws (30).The invention allows the gear profile to be optimally centered before final grinding of the gear wheel's (69) centre hole (72), thereby reducing the effects of any form defects, such as eccentricity in the gear wheel (69).<IMAGE>

Abstract: This ball bearing is designed mainly for use under high temperature. It comprises spacing elements 4 made from graphite which are substantially T-shaped, arranged between the balls 1 of a row of balls and curved to the shape of the pitch diameter of the row of balls. The vertical part of the T is interposed between two balls parallel to the axis of rolling and the horizontal part of the T is arranged on the side of the row of balls, all these horizontal parts of a row of balls being situated on the same side of the row of balls and forming an annulus which corresponds to the pitch circle of a row of balls. Flanges 7 mounted on one of the races of the roller-contact bearing prevent the spacing elements from falling out of the rolling-contact bearing. The spacing elements are produced from a bar-shaped blank having a T-shaped transverse section, which is cut into the required lengths with the aid of a cutting member, which reduces a circular cylindrical cut surface. <IMAGE>
