Title: Adjustable degausser
Inventor: CHANNEL WILLIAM D
IPC: G11B5/465
Filed: 1986-03-24
Granted: 1991-01-08
Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to devices which are designed to degauss magnetic read/write heads which heads are used in data or other recording on magnetic media.  The recording characteristics of a head deteriorate when it has a magnetic bias and a head used to follow high density data tracks may be forced by the bias to follow to one side or the other of a data track thus risking reading failure or misplaced writings.  Basically, this invention provides for a degausser which generates a sinewave which decays over time and which can vary the amplitude of that sinewave used in degaussing, the sinewave frequency, and its exponential decay rate, and it can vary these under software control, without changing any components.  It also corrects for D.C. offset in the degauss signal which would otherwise provide its own magnetic bias to the probe or workpiece.

Title: Exercise-responsive rate - adaptive cardiac pacemaker
Inventor: ALT ECKHARD
IPC: A61N1/365
Filed: 1986-11-06
Granted: 1991-10-15
Abstract: ABSTRACT OF THE DISCLOSURE  A temperature driven rate responsive cardiac pacemaker adapted to distinguish between physiologically determined changes of the patient's blood temperature under conditions of exercise and non-exercise, and to adaptively vary the rate at which stimuli are generated accordingly, is also capable of recognizing the blood temperature dip which is characteristic  of  the  commencement  of  exercise.    In response to such a temperature dip, the pacemaker initiates a  rapid  and physiologically  beneficial  increase  in  the stimulation  rate.     To  assure  the  proper  selective initiation of a rate increase, the pacemaker discriminates between a blood temperature drop indicative of the onset of exercise and those temperature drops which occur for other reasons, such as upon cessation of exercise or as normal phasic  variations,  including  respiration  and  circadian fluctuations.

Abstract: Procédé de préparation en microsuspension de latex d'homo- et co-polymères du chlorure de vinyle, dont les particules ont un diamètre moyen compris entre 0,2 et 0,8.mu.m et renferment au moins un initiateur de polymérisation organosoluble. Selon ce procédé, on réalise une dispersion fine du ou des monomères correspondants dans un milieu aqueux contenant au moins un émulsifiant anionique associé à au moins un émulsifiant non ionique, en présence de 0,004 à 0,16%, en poids par rapport au(x) monomères(s), dudit initiateur exprimé en oxygène actif, puis on réalise une opération de polymérisation, à température visée .theta.1, sur le milieu réactionnel ainsi formé. Avant de réaliser la dispersion du ou des monomères on ajoute du 2,6ditertiobutylparacrésol au milieu aqueux et au cours de l'opération de polymérisation on ajoute également du 2,6ditertiobutylparacrésol de façon continue, au milieu réactionnel, lorsque la température .theta.2 du milieu réactionnel est telle que l'écart .theta.2-.theta.l est superieur à une valeur choisie dans l'intervalle allant de 0 à + 5.degree. C et de préférence de 0 à + 2.degree.C. L'invention concerne également les latex obtenus qui sont utilisables comme produits d'ensemencement pour la préparation en microsuspension ensemencée d'homo- et co-polymères du chlorure de vinyle.

Abstract: ABSTRACT           UNIFORM WALL FLEXSPLINE        A strain wave gearing device comprising a ring gear having internal axially extending teeth and a strain gear produced from a strain gear blank having constant thickness to the cylindrical and diaphragm portions.  The cylindrical portion has external axially extending teeth extending around an annular portion adjacent the open end of the strain gear for engaging with the internal teeth of the ring gear (the number of external teeth on the strain gear being different than the number of internal teeth on the ring gear) and a wave generator is located within and matingly engages with the strain gear.  The wave generator adapted to be rotatively driven relative to the strain gear whereby relative rotational movement will occur between the strain and ring gears.

Title: High speed interconnect unit for digital data processing system
Inventor: DICKSON ROBERT
IPC: G06F13/36
Filed: 1987-07-23
Granted: 1991-06-18
Abstract: ABSTRACT OF THE DISCLOSURE      A digital data processing system transfers information with an external device through an interconnect unit over a bus which includes separates sets of lines for transferring control information and transferring user information.  The user information lines include a bidirectional information transfer lines and unidirectional antiparallel lines for transferring direction control signals and synchronization signals between the interconnect unit and the external device, the direction control signals identifying the direc-tion of transfer over the information transfer lines, and the synchronization signals identifying when the transmit-ting unit has transmitted the signals and when the receiving unit has latched the signals.  The control information lines include unidirectional antiparallel lines for transferring control information and a synchronization signal.  The syn-chronization signal is transmitted when control information signals are being transmitted on the control information lines.

Title: Sampled data tone control system
Inventor: CHRISTOPHER TODD J
IPC: H03G5/00

Granted: 1990-12-18
Abstract: Abstract A sampled data treble control system, requiring a single multiplier element, includes the cascade connection of a first adder, the multiplier, and a second adder coupled between the system input and output terminals.  A subtracter develops the differences between the system input and output signals and applies them to an IIR filter.          The filtered differences are scaled and coupled to the first and second adders.  The system transfer function H(Z) is given by H(Z) = [1+(Z-1)/(1+1/A)K]/[1+(Z-1)/(1+A)K] where A is a treble control variable applied to the multiplier, K is a scaling constant and z is the conventional Z-transform variable.
