Patent EP-0421018-A1 (EP)
Inventor: KRAUSE RALF-DIETER DIPL-ING
IPC: B23K20/10
Filed: 1989-10-06
Abstract: The welding in particular of wires and/or leads can be achieved in an advantageous manner via a sonotrode by application of force on the one hand and by ultrasonic action on the other hand by material deformation, preset over the welding time, in accordance with a predetermined lowering speed of the sonotrode. According to the invention, the lowering speed of the sonotrode is preset in accordance with the dimensions and/or configuration of the surfaces or their coating or is controlled in the form of a program. In the process, the lowering speed is advantageously changed from lower to higher values, and in fact preferably gradually. An electrically programmable motor drive (120, 125) is present in the associated device with a drive system of an ultrasonic welding press (100) consisting of lowerable sonotrode (101) and fixed anvil (102) for accommodating the workpieces (5; 6, 7). The infeed movement and the working speed can be preset separately in certain areas via associated means (135) for controlling or regulating the lowering speed of the sonotrode (1, 101). <IMAGE>

Abstract: Damping of a turbine rotor is attained by a weighted member (26) trapped between pockets (24) formed in the neck of adjacent blades (10) at one end and a space between the disk (36) and rotor seal (34) and forward extending blade lug (50) at the other end. The feather seal (52) which is a curved plate fits over the top of the weighted member (26) and is trapped between nubs (54,56) formed on the front and rear underside of the blade platform (20). The front face (46) of the rim of the disk (36) at the disk cavity is open ended and blocked off at the rear face. This assembly allows for individual blade removal and viewing from the rear face by removing a single rim cavity cover without disturbing the remaining compo­nents of the assembly. The inverted ring (76,78) sup­ports take up the axial loads alleviating the loads heretofore taken up by the TOBI rotor seal (36), allowing for a lighter weight installation.

Title: Crew oxygen mask with pneumatic comfort adjustment.
Inventor: AULGUR CHARLES C
IPC: A62B18/08
Filed: 1989-02-21
Abstract: A respirator especially constructed for flight crews has a harness strap which can be inflated to a somewhat rigid, self-sustaining orientation to permit one-handed placement of the respirator over the wearer's head. Once the respirator is in place, release of a lever for inflating the strap deflates the latter to an orientation sufficient to cause the resilient strap to tightly press a peripheral seal of the respirator mask against nose and mouth areas of the user's face. A comfort adjustment to relieve strap tension permits selective reinflation of the strap to a somewhat smaller value than necessary for initial donning of the harness, and the limited reinflation pressure is sufficient for causing the mask to seal against the face during pressure demand breathing. In instances where pressurized breathing is needed, however, pressure within the strap is automatically released so that the strap presents sufficient bias to hold the mask against the face without oxygen leakage therepast.

Abstract: A servo controller which, when the rotational direction of the servo motor is inverted, adds backlash correction data (B c ) to position deviation data (P c ) to generate a speed instruction (V CMD ) and adds backlash acceleration quantity (B ACC ) to the speed instruction to correct backlash. In order to terminate the backlash acceleration at a suitable timing, a counter (19) adds up the speed feedback pulses from a moment when the acceleration control is started, an acceleration stop instruction unit (20) monitors the added-up value of the speed feedback pulses, and an acceleration quantity output unit (21) no more produces the backlash acceleration quantity (B ACC ) when the added-up value has reached a predetermined value such as 2 or 3, thereby to complete the backlash acceleration control operation.

Abstract: A pneumatic spring of adjustable length has a valve (19) possessing a valve pin (46) which is arranged displaceably in a valve body (21). Arranged on both sides of a valve-body inner space (43) are O-ring gaskets (47, 50) which bear against cylindrical portions (48, 49) of differing diameter (d1, d2). Grooves (60, 60') are formed, at least for bridging an O-ring gasket (50, 47), in an associated cylindrical portion (49, 48). When the corresponding O-ring gasket (50, 47) is bridged as a result of the displacement of the valve pin (46), the respective O-ring gasket (50 or 47) remains bearing against the cylindrical outer face (62, 66) of the corresponding cylindrical portion (49, 48), so that there is no possibility that the gaskets will experience wear and therefore that the pneumatic spring will become useless.

Abstract: The invention supplements the use of a conventional authentication token such as a MAC or DSG, to provide very strong evidence of the origin of an electronic message. A new type of authentication token, known as the 'Non-Repudiation Vector' (NRV) is attached to each message sent across a data network. The NRV cryptographically links each message sent or received by a particular data processor on the network to previous and subsequent messages handled by that data processor, to create a chain of cryptographically linked messages. The burden of proof for the repudiation of a message is transferred to the sender of a message, who must demonstrate how the sending data processor could have moved through the time period during which the disputed message was sent, without generating the NRV corresponding to the disputed message.
