Abstract: An arrangement for butt coupling of waveguide electrooptic plates to form a crossbar switch. The arrangement includes a stack of M splitter plates, each of which routes an injected optical signal to one of N outputs, and a stack of N combiner plates, each of which routes the signal of a selected one of M inputs to a common output. The stack of splitter plates is rotated with respect to the stack of combiner plates and the output signal ports of the splitter plates are coupled to the input signal ports of the combiner plates, so that each output of an splitter plate is connected to a different combiner plate. Within each splitter plate there is a fan-out network of waveguide electrooptic couplers and each coupler, under electric control, routes signals from one input to either one of two outputs. With j levels of such interconnected couplers 2 j  output are developed. The combiner plates have an identical architecture but with a signal flow in the reverse direction. Butt coupling of the splitter and combiner plates is achieved by employing splitter and combiner plates of a different crystal cut, by interposing polarization rotation means between the two stacks, or by including polarization rotation means within the splitter plates, the combiner plates, or both.

Abstract: The invention concerns a sonar for avoiding sub-surface underwater objects. It is intended for installation in a surface vessel and its directivity in the angle of elevation or depression is optimized in order to scan the surface. In addition, surface reverberation is minimized. 
<??>The sonar uses an acoustic antenna (10) consisting of two columns of n transducers. On transmission, the first column sends acoustic signals over a sector of the angle of elevation or depression which corresponds to the region where there is a risk of collision. On reception, channels (F1 to Fk) are formed in the sector of the angle of elevation or depression over which acoustic signals have been transmitted, the channel widths being smaller the greater the desired precision in measuring the position in elevation. The second column of transducers is needed for location in relative bearing. 
<??>Application to the precise measurement of the angle of elevation or depression of objects situated in the path of a ship.

Title: Contour de tete magnetique utilisant les facettes pour la suppression du film d'air
Inventor: BROCK GEORGE WILLIAM
IPC: G11B5/187
Filed: 1990-04-02
Abstract: Dans le but de supprimer le film d'air adhérant à une bande magnétique en mouvement (28), plutôt que d'avoir la bande magnétique (28) incidente sur un épaulement abrupt de la tête, une facette (20, 22) du contour forme une pente graduelle qui casse la continuité du contour de la tête (18). La cassure du contour constitue un bord (38, 40, 42, 44) qui rejette et enlève l'air adhérant à la bande, et la facette (20, 22) forme une surface avec rampe douce qui entre en contact avec toute aspérité à la surface de la bande (28) d'une manière moins agressive que lorsque l'aspérité vient à l'encontre directe d'un épaulement. A cause de la rigidité de la bande (28), cette dernière n'entre pas en contact avec le contour de la tête sur la longueur de la facette (20, 22); la bande (28) enjambe le contour entre les bords (38, 40, 42, 44) de la facette (20, 22). L'air rejeté de la bande (28) au moyen du bord (38, 40, 42, 44) de la facette (20, 22) est expulsé entre la bande (28) et la facette (20, 22), et une fente (48, 50) dans la facette (20, 22) augmente la surface de la section au travers de laquelle l'air est expulsé. La bande (28) enjambant la facette (20, 22) n'est pas en contact avec les bords (38, 40, 42, 44) de la fente (48, 50), et les problèmes relatifs aux bords rencontrés dans l'art antérieur sont éliminés avec la présente invention.

Title: Variable speed ac drive control.
Inventor: ECKERSLEY GREGORY P
IPC: H02P27/04
Filed: 1990-09-11
Abstract: A method for controlling the speed of an AC machine (12) is described. The AC machine (12) receives three output phases (A, B, C) supplied from a cycloconverter (10) which is connected to an input supply (R, Y, B) of frequency f1. The cycloconverter (10) is caused to operate in three modes under control of a microprocessor (25). The first mode supplies the AC machine (12) in the frequency range 0 to fo, by conventional cycloconverting to generate a near continuum of frequencies. The second mode operates the cycloconverter (10) to synthesize a number of frequency steps in the frequency range fo to f1 from the input supply (R, Y, B) and provides speed control of the AC machine (12) by phase control of the output voltage (A, B, C) between each frequency step. The third mode operates the cycloconverter (10) to be transparent, such that the input frequency f1 is effectively directly supplied to the AC machine (12) without speed regulation being applied.

Abstract: Means which limit the lock angle which can be adopted by a vehicle's wheels, for example after fitting snow chains, in order to avoid interference with the wheel arch is described. The means consist of a sliding pin operated by an electromechanical actuator which can be controlled from the vehicle's dashboard and/or by means of a sensor located close to the wheels. The pin is mounted transversely to the steering shaft, in front of a travel limiting block which normally acts in concert with a corresponding joint which connects the steering shaft to a corresponding track rod to establish the limiting lock of the corresponding wheel and when in a pulled out position acts in concert with the joint before this comes into contact with the travel limiting block, thus defining a new more restricted limiting lock for the corresponding wheel.
