Abstract: A damper system has a rotatable, damper blade pivotally mounted within a damper body. The inner wall of the damper body has a plurality of inwardly, radially extending pins over which is fitted a generally U-shaped sealing channel. The sealing channel comprises two members each of which is held in compression against the inner wall of the damper body by adjustable hold-down blocks.

Abstract: The compounds of formula I are useful in treating gastrointestinal disorders associated with antagonizing the motilin receptor disorders. The compounds compete with erythromycin and motilin for the motilin receptor. In addition the compounds are antagonists of the contractile smooth muscle response to those ligands.

Abstract: An output vector produced by a plant in response to an input vector is filtered by a plurality of bandpass filters, each filter having a different pass band. A filtered output vector from each filter is provided as input to a separate adaptive feedback controller, and feedback vectors produced by the separate controllers are summed to provide the input vector to the plant. Each adaptive feedback controller continuously identifies an open-loop transfer function of the plant characterizing a particular frequency band of plant operation, and continuously adjusts its own open-loop transfer function so that the poles of the closed-loop transfer function of the plant for that particular frequency mode of operation are assigned to constant stable values despite changes in the open-loop transfer function of the plant.

Abstract: A circuit for controlling the drive direction of an electrically-driven vehicle, the circuit having a plurality of spring return input switches (20) each actuation of which changes the direction of the vehicle, via a flip-flop circuit (21), an amplifier (22), and a relay (13); the direction contactor coils (10, 11) of the vehicle being connected in alternative circuits through the contacts of the relay (13).

Abstract: In a diaphragm spring clutch cover assembly one of the annular fulcra for the diaphragm spring is cushioned in order to supplement or replace the cushioning normally incorporated between the friction facings of the driven plate. The cushioning in the fulcrum includes a wavy ring some of whose undulations are of greater height than the others to give a progressive engagement of the clutch.

Abstract: This disclosure relates to a wheel-band type continuous casting machine wherein the endless flexible band is guided about the rotatably mounted casting wheel by means of a plurality of flangeless guide wheels, and is restrained from movement in a direction parallel to the axis of rotation of the casting wheel by means of band guides adapted to engage opposite edges of the endless band. The band guides comprise a plurality of rollers rotatably mounted adjacent the edges of the band with their axes of rotation arranged perpendicular to the direction of band movement therepast whereby the rollers are adapted to engage the edges of the band in rolling point contact. Means are provided for adjusting the position of the band guides with respect to the bands.
