Patent EP-0449048-A1 (EP)
Inventor: CULP GORDON WALTER
IPC: H02N2/10
Filed: 1991-03-14
Abstract: A rotary motor uses a plurality of radially acting piezoelectric actuators to impart rotation to a motor shaft having surface undulations. Electrical charge distributed to the actuators causes radial actuator motion resulting in contact between the actuators and the sloped sides of the shaft undulations. The slope of each undulation transforms the radial force into tangential force that rotates the shaft. The slope of the shaft undulations provides a mechanical advantage that transforms the slow radial speed of the actuators into greater shaft rotational speed. The shaft undulations can be made in any desired or easily fabricated shape. The electrical actuation control signals can be modified electrically to produce appropriate radial actuator motion to match the undulations of the shaft. Electric charge can be shared among actuators by using switches or other circuitry. Efficiency can be increased further by using acoustic excitation and by using rollers for contact between the actuators and the shaft.

Abstract: In a device for spinning a yarn (4), in particular a ring spinning machine, a flyer or the like, with bobbin openings, aspirator ducts or the like for aspirating fly-contaminated air into the interior of a housing (1), the openings, aspirator ducts or the like are to be formed by appropriate guide sheets on the housing. To avoid undesirable deposits of fly in dead corners and angles it is proposed that the cross-section of the openings (12), aspirator ducts (22) or the like should be at least partially and/or temporarily variable during the spinning process. <IMAGE>

Abstract: A disc brake assembly has a rotor (12), a cylinder housing (16,18) and a brake pad (76) and associated carrier (74) displaceably mounted on the housing. Piston means (46,48,50) mounted on said housing (16,18) are arranged to displace the pad (76) into engagement with the rotor (12). The brake pad (76) is tapered in width along its length. The inner surface of the brake pad (76) positioned adjacent to the rotor (12) is mounted on the carrier (74) such that a leading edge (104) of the pad (76), which is first swept by the rotor when rotating in a forward direction, is wider than a trailing edge (106) of the pad (76). Thus, the paper is oriented in the direction of forward rotor (12) rotation such that the area of the pad (76) adjacent to the leading edge (104) is greater than the area adjacent to the trailing edge (106), whereby even wear of the inner surface is promoted.

Abstract: An information transfer system transfers stimuli, each having an associated operation identification value, among processes. The information transfer system includes a queue database to hold stimuli and associated information and a queue manager to control receipt of the stimuli in, and transmission of the stimuli from, the queue database. The transfer of stimuli first requires a registration operation. If the process has previously used the information transfer system and has not performed a deregistration operation, the queue manager assumes a failure has occurred and provides to the process recovery assisting information, such as the last stimulus the information transfer system received from or transferred to the queue database.
