Abstract: This invention relates to a process for the separation of moprolol into its two optical antipodes, substantially characterized by the fact of salifying racemic moprolol with L(+)glutamic acid; treating the thus obtained mixture of diastereoisomeric salts with a water/alcohol mixture, in this way separating the L(+)glutamate insoluble salt of (+)moprolol; treating the resultant mother liquors which contain in solution the L(+)glutamate salt of (-)moprolol with a base so as to separate the laevorotatory isomer of crystalline moprolol, which finally undergoes a purification. The invention also relates to a pharmaceutical composition containing said laevorotatoryisomer of moprolol.

Abstract: An oil burner ignition system includes a transformer primary winding feedback coil and dual secondary coil wound in axially coextensive and mutually coupled relation about a ferrite core. The primary winding and feedback coil are wound continuously about the core and disposed within a bobbin which supports the secondary coil. The primary and feedback coil have a common end connection in circuit with the emitter of a switching transistor. The other end of the feedback coil is connected through a capacitor and resistor circuit to the base of the transistor. The collector and base of the transistor are connected by a circuit to receive unipolar pulses of electrical energy. A resistor is connected between the base and the collector of the transistor to bias the transistor "on". The feedback coil is disposed to have voltage induced therein by changing current flow through the primary winding and the collector-emitter electrodes of the transistor.

Abstract: An interferometer wherein the deviator element, that is the means whereby the interferometer optical elements are optically coupled together, the incident beam is admitted into the interferometer, and the beams to be made to interfere with one another are extracted therefrom comprises, according to a first embodiment a prism whose faces are uncoated and according to a second embodiment a diffraction grating. Basing on the above concept various optical arrangements are described which are referable to known arrangements such for instance the Fox-Smith, the Michelson, the Petrun'kin interferometers wherein the deviator element is replaced, according to this invention by a prism or by a diffraction grating functioning as reflectors. Specifically the use is disclosed of an interferometer as an output coupler of a laser optical resonator.

Abstract: A number of component parts may be recombined to form a number of different martial-arts weapons. The many different types of weapons that may be formed is achieved via three elongated basic components interconnected together by male and female couplers, and a number of secondary components also connected to the three basic components by male and female couplers. One secondary component is chain for connection to one end of a basic component or between adjacent ends of two basic components. A number of other secondary components allows for many other different weapons to be formed. The recombinative and collapsible nature of the components also allows for ease of transport.
