Patent EP-0245809-A2 (EP)
Inventor: PAYNE PETER P
IPC: F16H35/10
Filed: 1987-05-09
Abstract: A drive torque limiter comprises a wheel-shaped driving member (18) having a center hole (34) which is sized for a substantial slip fit over a driven shaft (36). A friction plate (38) is located on at least one side of the driving member; the friction plate (38) rotates without slippage with the shaft (36,40). Locking means (44,46) are provided for preventing the driving member and the friction plate from sliding longitudinally on the shaft. A spring (48) biases the driven member and the friction plate together. 
     An annular-ring surface (50) is located on the friction plate (38) or the driving member (18) or both. The annular-ring surface is substantially concentric with the driven shaft (36,40) and forms an annular-ring interface between the friction plate and the driving member. The transmitted torque between the driving member and the driven shaft is limited by frictional force between the friction plate and the driving member at the annular-ring interface.

Abstract: In a process for checking and/or acquiring the dimensions, changes in dimension, the position and changes in position of workpieces, regulating elements or the similar, a measured or regulated quantity is picked off by a tracer and transferred to an elastically deformable measuring element. In order to avoid the inconvenients of the use of a spring as a converter of measured values and to make it possible to use measuring apparatus belonging to the same system with as much similar parts as possible for a large range of measurements, the displacement of the tracer is converted via a special, relatively soft spring into a force that corresponds to the measured or regulated quantity and transmitted to a sensor.

Abstract: There is disclosed herein an ECL gate using switchable load impedance means to allow the gate to be placed in a low power-consumption mode while preserving the logic state existing at the outputs of the gate at the time it is switched into the low-power mode. N-channel or P-­channel MOS transistors (M2,M3) are used as the switchable load impedances. The gates of these transistors (M2,M3) are coupled to a MODE control bus (12) which causes the MOS transistors (M2,M3) to switch between high-impedance and low-impedance states. Another MOS transistor (M1) having its gate coupled to the same MODE control bus (12) is used as the current source for the bias current to the conventional ECL current mirror (10). When low-power mode operation is desired, all the MOS transis­tors (M1,M2,M3) are switched to their high-impedance state. This reduces the bias current flowing through the ECL gate, thereby reducing its power consumption. The logic states at the output nodes (24,26) are preserved by virtue of the load impedance of the ECL switching transistors (Q1,Q2,Q3) having increased simultaneously with their collector currents having decreased.

Output signals from sensors are fed to evaluation electronics provided on the turntable itself. Each station has a plate on which a bottle can be rotated as a result of rotation of the turntable. During inspection each bottle executes an orbital movement about the vertical axis of the turntable and at the same time a rotation about the axis of bottle itself as a result of which each bottle is inspected more than once for perpendicularity of the bottom of the bottle and its neck as well. Volume and pressure tightness as well as height of the bottle and bottle color are also inspected.

Abstract: The invention provides a connector, a transmitter, a bi-directional device, and a method for increasing the reliability of borehole detonation by using the connectors and transmitters provided by the invention. The invention provides connectors, each connector having a well for receiving a blasting cap, one or more ports or channels for receiving a transmission line and/or downline, and means for joining one connector with another connector in a convenient manner. The connectors are constructed so that detonation of a blasting cap in one connector will cause sympathetic detonation of a blasting cap in an adjoining connector. The detonation of blasting caps in the connectors also causes initiation of transmission lines and/or downlines which are inserted in the ports or channels through the connectors. A transmitter is comprised of one or more of these connectors with the transmission lines being arranged so that the transmitter receives a signal from one line and outputs it to at least one other transmission line or downline. A bi- directional device is provided that consists of a transmission line with blasting caps attached to each end and the caps are inserted into the wells of connectors as described below. The method of the present invention includes the use of the transmitters and arranging them such that there are at least two signal paths from which a transmitter may receive an initiation signal.

Abstract: A liquid crystal device includes a liquid crystal material (30) in which the molecules (15) form a helix having its axis essentially parallel to the plates (13,20) of the device. A suitable electric field (E), applied essentially perpendicular to the plates, causes planes of the directors (n) to rotate about the field direction to an acute angle φ with respect to the helix axis, thereby inducing alternating bands of splay and bend in the material. Such configurations, which have polar symmetry, give rise to the flexoelectric effect in which the polarization (P) of the molecules tends to be parallel to the applied field, and the magnitude of the field is linearly related to tan φ. The ability to rotate the directors means that the optical properties of the material can be changed.
