Abstract: A locking device for a folding top on the windscreen frame of a motor vehicle comprises a pivot lever arranged on the top side and a retainer provided on the windscreen frame, the pivot arm mounted about an approximately horizontally aligned longitudinal axis cooperating with an actuation device. …<??>In order to provide a locking device for a top, which device has a simple design and functions well and whose closing force acting in the vertical direction reaches its maximum value in the locking position of the top, the retainer is formed by a rotatable roller which corporates with a guide path provided on the pivot lever in such a way that during the closing process the guide path is moved from an unlocking position running laterally next to the roller around the lower region of the roller via intermediate positions into a locking position lying below the roller. The points of rotation of the pivot lever and of the roller are located on a common, vertically extending auxiliary plane. During the closing process, the upper point of rotation of the pivot lever on the auxiliary plane moves downwards. In the locking position, the area of the guide path at a tangent to the roller is aligned at right angles to the vertical auxiliary plane. …<IMAGE>…

Abstract: In a light emitting diode comprising a plurality of layers (501 to 503) deposited on a substrate (504), the substrate (504) is etched so as to reduce the area in which the substrate is attached to the plurality of layers. The reduction in the area of attachment results in less light being absorbed by the substrate and thus more total light shining forth from the light emitting diode.

Abstract: In the shared transmission of digitised television, sound and data signals, these signals require different channel capacity. This makes it more difficult to accommodate them in existing standardised transmission links. The invention provides a remedy in that n-1 channels of a transmission link combining n channels are allocated to the transmission of television signals and one channel is allocated to the transmission of sound and data signals. The channels are designed to be identical with respect to one another so that identical assemblies can be used for the shared signal processing. In the channel for sound and data signals, television programme sound signals are also transmitted. In addition, structure and synchronising signals for the entire system are also transmitted in the additional channel.

Abstract: A binder assembly comprises a cover 210, 211, 212 to which is securable a ring binding mechanism 215 which includes a base plate 216. The base plate 216 is secured to the cover by a two-part fastening device 218 comprising a male part 219 having a threaded shank 221 which passes through registering holes 222 and 223 in the cover and base plate and which is adapted for screw-­threaded engagement with a female part 224. The female part 224 is formed from plastics and is integral with a manipulating part 225 which may be snapped off after the fastening device has been secured in place. Alternatively, the male part may pass through the base plate of the ring binding mechanism and engage a female part in the cover. The female part, instead of being a separate element, may comprise a blind hole integrally formed in the cover. The two parts of the fastening device may be in snap-in, rather than screw-threaded, engagement.

Abstract: An apparatus and a method for profiling the intensity of a beam and thus measuring the overall intensity and power of a beam are disclosed that have particular use in stereolithography. A beam sensor comprising a pinhole in a plate and a photodetector behind the pinhole measures the intensity of portions of a beam as the beam is moved over the beam sensor. Software associated with the sensors in a computer controls the scanning mechanism for the beam so that the beam is shifted to find the pinhole and move across it in order to develop the intensity profile. The invention can be used to detect drift in the scanning mechanism, determine the focus of the beam, and predict the depth and width of photopolymer cured by the beam. A related apparatus and method for calibrating and normalizing a stereolithographic apparatus is described, and a related apparatus and method for correcting for drift in production of objects by stereolithography, is also described.

Abstract: In a depletion mode thyristor of the type including a regenerative portion (32,34,36,38) and a non-regenerative portion (32,34,34a,36a), the turn-off time for the thyristor is substantially reduced without producing a corresponding increase in the on-resistance of the device by providing a region of relatively low carrier lifetime (34a) in the non-regenerative portion of the device in the layer (34) or layers in which charge storage limits the turn-off time for the device. Turn-off of the thyristor is accomplished by pinching off the regenerative portion, thereby diverting current into the low carrier lifetime non-regenerative portion.
