Abstract: Methods and compositions are provided for asymmetrically donating an oxygen atom to a pair of electrons to produce an asymmetric product which is a valuable technique in the synthesis or modification of a natural product. A metal alkoxide is used as a catalyst, where the metal has a coordination number of at least four, and at least one, usually two, of the alkoxide groups bonded to the metal are bonded to asymmetric carbon atoms. The metal catalyst is employed in conjunction with a hydroperoxide and an alkanol having a functionality with a pair of electrons capable of accepting an oxygen atom. The resulting product is enriched in one enantiomer due to the enantioselective introduction of an asymmetric center or an enhanced rate of reaction of one of the enantiomers of a chiral alkanol. A preferred metal for the catalyst are titanium, and for the alkanol a tartrate derivative, and such compounds are claimed per se.

Abstract: System for safety devices comprising a comparator connected to an output element such as a relay itself connected to an alarm device. This system consists in alternately performing a measurement and a monitoring in the course of which a fault is simulated in such a way as to cause the comparator to deliver a signal which only excites the said output element, and consequently the alarm device, if the alternation in the monitoring and the measuring signals disappears.

IPC: H02P8/20
Filed: 1982-04-28
Abstract: A method and apparatus for controlling a stepper motor and a disk drive is described for minimization of stepper motor oscillations for a single step, minimizing the time taken for the stepper motor to move between tracks for multi-track seeks, and reduction of angular hysteresis due to the mechanical and magnetic properties of the stepper motor construction. This control is achieved using a microprocessor-based circuit adapted to drive the stepper motor in accordance with predetermined programs. Oscillations of the stepper motor are damped by controlling, using one program, the current applied to the stepper motor during the last step of its motion by switching this current on and off within small predetermined time intervals. The time taken to move between tracks is controlled by another program in which the non-linear torque speed characteristics of a particular stepper motor are matched by a non-linear pulse rate which is determined by data held in the memory of the microprocessor circuit. This data can be modified to suit the requirements of the stepper motor and load. Another program controls minimization of hysteresis by ensuring that each track on the disk is approached from the same direction and from the same previously energized set of windings. The microprocessor controls the direction of motion of the stepper motor and hence decides whether or not the read/write head should cross the desired track and return it to ensure uniformity of approach.

Abstract: L'invention concerne le domaine de la technologie de construction de bâtiments et porte sur la partie d'isolation thermique du mur extérieur d'un bâtiment. (Elle peut également s'appliquer à des planchers et à des plafonds). D'autres murs dans le bâtiment peuvent également convenir, dans le cas de différences de température entre espaces et pour des besoins de ventilation. L'invention est conçue pour être utilisée aussi bien pour des espaces chauffés que pour des espaces froids, et s'attaque au problème des pertes d'énergie relatives à la ventilation, à l'humidité de l'air dans une pièce et à la température des surfaces. Le principe fondamental de l'invention consiste dans le fait que le mur est construit pour constituer lui-même un échangeur thermique de type à contre-courant et pour transmettre l'humidité et la chaleur de l'air refoulé (air frais) à l'air frais (air refoulé). En même temps, on obtient une température des surfaces égale à celle de l'air ambiant.
