Abstract: 1. System for radio transmission of a binary-coded signal, having circuit means (111, 112, 113) at the transmitting end which convert the signal in a suitable manner and modulate the converted signal upon a radio-frequency signal in any type of modulation suitable for the transmission of analog signals, and having circuit means at the receiving end which demodulate the radio-frequency signal and supply the demodulated signal to a limiter (201) delivering a bipolar signal dependent upon the momentary polarity of the signal applied thereto, characterized by a formation of the said transmitting-end circuit means (111, 112, 113) such that these circuit means convert a binary value of a first kind (0) supplied to them into a single, complete sinusoidal oscillation (Fig. 4) of a first frequency and a binary value of a second king (1) supplied to them into a sequence (211) consisting of an oscillation packet of a second frequency and a single, complete oscillation of the said first frequency, the said second frequency being a multiple in excess of three of the said first frequency, and the said single oscillation having the same shape in all cases, and characterized by a receiving-end series connection consisting of a low-pass filter (202) and a threshold-value detector (203) for converting the output signal (212) emanating from the said limiter (201) into a binary signal (214), the low-pass filter (202) having a critical frequency situated between the said first and second frequencies, and the threshold-value detector (203) suppressing in each case the first semi-oscillation of the said oscillation (213), whereby this series connection delivers a signal (214) consisting of a pulse train, the pulses of which correspond to half an oscillation of the first frequency and the pulse separations of which correspond either to the duration of half an oscillation of the first frequency or to the sum of the duration of an oscillation packet of the second frequency and the duration of half an oscillation of the first frequency.

Abstract: Un assemblage de jante de pneu (16) ne permet le gonflement d'un pneu (10) monté que lorsque les éléments qui composent la structure sont assemblés selon une configuration de verrouillage. L'assemblage de jante de pneu (16) comprend une base de jante (18) ayant une première et une deuxième rainures (32, 34) définies sur sa périphérie extérieure (30), un siège annulaire de talon (24) agencé autour de la base de jante (18) et ayant une périphérie intérieure (38) qui définit une surface de transfert de charge (42), une surface intérieure (40), et une surface en pente (44) située entre la surface intérieure (40) et la surface de transfert de charge (42). Un joint élastomère (26) est disposé dans la deuxième rainure (34), et une bague annulaire fendue de verrouillage (28) s'emboîte dans la première rainure (32) de manière à limiter son déplacement axial et à entrer en contact avec la surface de transfert de charge (42) du siège de talon (24) lorsque l'assemblage de la structure est achevé. Le joint élastomère (26) est positionné par une surface de guidage (52) de la bague annulaire fendue de verrouillage (28) et déformé élastiquement en s'engageant dans la surface en pente (44) afin d'établir un joint d'étanchéité entre le joint élastomère (26), la deuxième rainure (34) et la surface en pente (44) lorsque la bague de verrouillage (28) est correctement installée. Lorsque la bague de verrouillage (28) est oubliée ou installée incorrectement, le joint élastomère (26) n'est pas soumis à compression et ne forme pas un joint d'étanchéité.

Title: Method and apparatus for indicating misregister of  overlapping printed images
Inventor: BROVMAN YAKOV Z
IPC: B41F13/02
Filed: 1983-05-04
Abstract: Method and apparatus are disclosed for indicating and correcting misregister of plural overlapping images produced by a multicolor press. A register indicia (Fig. 3) is used comprising two overlapping sets of parallel lines (R and C), each set being formed in a known position relative to a corresponding one of the images whereby the positional relationship between the sets of lines varies with the positional relationship of the images. The extent of overlap of the sets of lines is dependent upon displacement of the sets of lines in a direction transverse to the lines, whereby the percentage of nonprint area in the register indicia is dependent upon register of the overlapping images in that transverse direction. The percentage of nonprint area is detected by illuminating the register indicia area and measuring the extent to which the area reflects the light. The resulting signal is used to control the register adjustment mechanisms of the multicolor press.

Abstract: A friction material member particularly useful in high load and temperature applications and a method for making the same are disclosed. The friction material member is made by preparing a mixture of sinterable metal particles, carbonaceous material, friction enhancers and curable polymeric resin; the mixture comprising at least about 50 percent by weight of metal particles and sufficient resin to coat and bond the metal particles, carbonaceous material and friction enhancers. The mixture is molded and the resin cured to form a piece in a solid preformed shape corresponding to the shape of the mold. Thereafter, the preformed piece is heated in a substantially oxygen free atmosphere for a time and at temperatures and pressures sufficient to fuse at least a portion of the metal particles into a sintered metal matrix. The preformed piece may be sintered to a metal backing plate during the heating step, or may be welded, brazed or soldered to the plate after heating. The resulting product may be classified as a hybrid friction material, i.e., being a cross between semi-metallic and sintered full metallic friction materials.

Abstract: A non-impact printer in which a source of image information (36) such as a computer, facsimile machine, word processor or the like provides image information to an image transfer device (38) which transfers the image to a moving image receiving surface (14) for printing of the image as hard copy. A motion encoder (20) senses the motion of the image receiving surface (14) and creates a digital timing signal representative of the motion. A logic circuit (32) selectively delays the input of the image information signal to the image transfer device (38) in response to digital timing signal to synchronize motion of the image receiving surface (14) with transfer of the image to the image receiving surface (14).
