Inventor: MCKALE GARY WILLARD
IPC: B01D29/39
Filed: 1982-03-19
Abstract: A filter leaf is disclosed which is particularly suitable for supporting a layer of a fibrous or particulate filter material such as diatomaceous earth, among others. The leaf comprises a pair of fine mesh filter screens (30) positioned on opposite sides of a system of backing sheets (24) and a drainage screen (20) which are framed by a member (12) to which the fine mesh screens are continuously bonded. The arrangement enables the fine mesh screens (30) to be stretched and tensioned such that the particulate or fibrous material does not migrate and form cracks during filtering.

Title: Exerciseur de la cheville
Inventor: LEPLEY CHELSEA
IPC: A63B23/08
Filed: 1982-03-05
Abstract: Un exerciseur de la cheville (10) permet d'effectuer des exercices isocinetiques de l'articulation de la cheville de l'usager. Le pied de l'usager est fixe sur une plaque de pied (54) par une sangle (124). La plaque de pied est capable de bouger autour de trois axes perpendiculaires entre eux (X-X, Y-Y, Z-Z), dont un axe correspond a l'axe de pivotement de l'articulation de la cheville en flexion dorsale et plantaire. Le mouvement autour de chaque axe est limite par un cylindre a fluide a double effet (64, 82, 104). Des valves de mesures individuelles (160, 162, 164) sont prevues pour limiter le flux entre les chambres des cylindres et un reservoir (152) pour determiner selectivement la resistance desiree au mouvement. Des jauges de pression (154, 156, 158) sont associees a chaque cylindre pour indiquer la force exercee par l'usager a laquelle resiste le cylindre particulier. Dans un second mode de realisation, un exerciseur de cheville (250) permet d'exercer les deux chevilles de l'usager. Les plaques de pied (282, 284) sont pourvues de sangles pour fixer les pieds de l'usager sur ces plaques. Les plaques de pied sont montees en mouvement autour d'un axe (V-V) qui correspond sensiblement a l'axe du mouvement pivotant des articulations des chevilles en flexion dorsale et plantaire. Un cylindre a fluide (296) et des valves de mesures (304, 306) permettent de determiner independamment la resistance au mouvement des plaques des pieds et la resistance dans chaque direction. Des jauges de pression (300, 302) sont prevues pour controler la force exercee par l'usager.

Abstract: 3-Aminopropylpivalamide is prepared by contacting pivalic acid with 1,3-diaminopropane at temperatures above the boiling point of 1,3-diaminopropane and the latter is distilled off. The residue may be refluxed to provide 2-t-butyltetrahydro-pyrimidine. In a further step 2-alkylpyrimidines are obtained by dehydrogenation of the tetrahydro-pyrimidines over a supported noble metal catalyst under conditions which do not generate water and in which no water is added.

Inventor: MONKS DAVID E
IPC: G03B7/16
Filed: 1983-01-13
Abstract: An electronic strobe flash unit in a camera is charged in response to actuation of a shutter-release member. To assure that the flash capacitor has sufficient charge to fire the strobe flash at the time of shutter release (i.e. exposure), a logic circuit i66) functions to delay shutter release for a variable time interval, up to about 0.75 second. To assure that the exposure is effected after such time interval, the logic circuit is designed to operate only in response to the shutter releasing member being moved to a position in which shutter release is irreversibly initiated (i.e. its shutter-releasing position). This variable time delay is long enough to assure that the flash capacitor is charged sufficiently to produce a flash regardless of its previous condition, but is sufficiently brief to avoid disturbing the camera operator.

IPC: G11B5/58
Filed: 1983-05-06
Abstract: A misposition correction system for correcting misposition errors due to spindle runout and other slowly varying errors in a servo positioning system of a magnetic disk storage device. The system includes means for dynamically measuring misposition error with respect to a data track centerline using an anti-aliasing analog filter, means for digitizing the measured analog signal and for removing selected harmonics of the fundamental-frequency of the resulting cyclic error signal, means for transforming the digitized error signal by a matched digital filter whose transfer function contains independently adjustable DC gain, fundamental-frequency gain, and phase lead components thereby to generate a misposition error correction signal that matches the electrical and mechanical response characteristics of the servo system. Further, the system include means to iteratively refine the correction signal by re-applying it to the servo controller when measuring misposition errors with respect to the data track centerline. The system stores separate misposition correction signals for each transducer on the disk so that one of several correction signals can be selected depending on which transducer in the device is selected. The system further includes means for generating a bias force correction signal to correct for non-linear position errors resulting from variations in bias forces acting on the transducer carriage over its range of radial displacement.
