摘要:
An electromagnet including a magnetizable yoke, an exciter coil system, and a movable armature. The end surface of at least one pole shoe carried by the yoke is divided into at least two discontinuous partial surfaces separated by a space. At least one control coil system includes a coil at least partially within the space and arranged to produce magnetic flux passing through the partial surfaces in opposite directions.
摘要:
An electromagnetic drive for rotary bodies including a stationary member having at least two coils and a revolving member arranged for rotation with respect thereto. The coils are supplied with a current signal for causing rotation of the revolving member and a sensing arrangement senses the position of the revolving member with respect to the stationary member and provides an output indicative thereof. A control device is responsive to the output of sensing arrangement for supplying an additional current signal to the coils effect positional control of the revolving member.

Indoles having aryloxyalkanoic acid substituents or arylalkanoic acid substituents are agonists or partial agonists of PPAR gamma and are useful in the treatment and control of hyperglycemia that is symptomatic of type II diabetes, as well as dyslipidemia, hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, and obesity that are often associated with type 2 diabetes.

摘要:
A method and arrangement for the traversing of critical rotational speeds of elongate rotors. At least one critical frequency altering means in the form of springs, dampers and masses may be operatively connected, singly or in combination, to the rotor to thereby produce a change in the frequencies and/or amplitudes of the rotor, or in the critical rotational speeds and their amplitudes.

摘要:
This invention relates to the use of potent potassium channel blockers or a formulation thereof in the treatment of glaucoma and other conditions which leads to elevated intraoccular pressure in the eye of a patient. This invention also relates to the use of such compounds to provide a neuroprotective effect to the eye of mammalian species, particularly humans.
摘要:
In order to perform an ice-breaking operation more readily or with a defined geometry, an ice breaking aid is employed by virtue of which the ice is irradiated with high-frequency oscillations such as phonons or photons prior to the ice-breaking operation proper.
摘要:
A method and device for automatically steering a trackless vehicle along a routing or guide line. A scanner senses the position of the longitudinal centerline of the vehicle with respect to the guide line and produces a position signal. A datum transmitter produces a datum signal. A comparator compares the two signals and produces a difference signal which is used by a control unit to produce a steering signal. In producing the steering signal, the device distinguishes between influences on the vehicle position caused by interference, e.g., wind gusts and rough roads, and influences caused by curvature of the guide line. The steering signal causes adjustment of the steering angle of the vehicle to minimize the distance between a reference point on the longitudinal centerline of the vehicle and the guide line.
摘要:
A drive arrangement for a rotor which facilitates the rapid and convenient exchange of the rotor in that a magnetic coil system is located along the conical circumferential surface of the rotor, whose inner surface forms an air gap with the conical circumferential surface of the rotor of an essentially uniform width. This magnetic coil system, on the one hand, serves for the generation of a magnetic field oriented inclined relative to the rotor aixs, and whose adjusting effect causes the rotor to maintain the prescribed air gap without contact, while the coil system additionally serves to provide a magnetic rotational field which drives the rotor.
