Abstract: An optical beam phase shifter includes a liquid crystal cell having a common electrode (12) on a first windows and a multiplicity of parallel stripe electrodes (14) on a second window. A multiplicity of control signals are applied between the individual stripe electrodes (14) and the common electrode (12), thereby creating local variations of the refractive index of the liquid crystal molecules (13) therebetween, which variations cause differential phase shifts across the cross section of a light beam (18) incident thereon. An optically-refractive element (11), having an index of refraction greater than the index of refraction of the liquid crystal material (13), is interposed between the beam (18) and the liquid crystal material (13). The refractive element, illustratively a prism (11), increases the angle of incidence of the beam (18) entering the liquid crystal material (13), thereby increasing the beam travel distance through the liquid crystal molecules. This allows the use of a thinner layer of liquid crystal molecules, and hence, improved response time of the optical beam phase shifter to changes in the control signals, and reduced fringing effects between stripe electrodes (14).

Abstract: A continuously variable transmission on a motor vehicle is controlled by establishing a target acceleration Go to be reached according to an indication of the driver's intention for acceleration or deceleration, such as the amount of depression of the accelerator pedal, and also to an indication of the speed of the motor vehicle. A present calculative acceleration G CAL  is calculated on the basis of a reserved power Pa of the engine which drives the continuously variable transmission. A target acceleration Gon required at the present time to vary the present acceleration up to the target acceleration Go to be reached along a desired characteristic curve is established according to the difference ΔG (= Go - G CAL ) between the target acceleration Go to be reached and the calculative acceleration G CAL . Then, the throttle valve of the engine on the motor vehicle and the continuously variable transmission are controlled so that the target acceleration Gon will be reached.

Abstract: The invention relates to means for retaining contaminations in metal melting baths, e.g. a tundish containing molten metal. 
     Contaminations, e.g. from slag and other covering layers on the metal surface, can pass through the outlet of the tundish and hence contaminate the cast metal. The invention aims to avoid this problem by providing an annular buoyancy body (2) which surrounds the outlet (4), the body (2) being in the form of a protective ring preventing particles (10, 11) floating on the surface of the metal (12) from entering outlet (4). The body (2) may be constrained to surround a starting tube (1) which surrounds outlet (4) and to float up the starting tube (1) with increasing depth of molten metal (12). Pouring openings (3) in the starting tube (1) are thereby effectively closed by body (2) as the slag-covered surface of the metal (12) rises above the openings (3) and the openings (3) are then exposed to allow molten metal (12) to flow through only after layers (10, 11) of potential contaminations have safely passed.

Abstract: Disclosed herein is a control device which is suitable for use in a radio communication apparatus employed in a radio communication system using a TDMA method. A timer circuit (20) for circulating a counted value in a period corresponding to a period of time required to transmit a TDMA frame supplies the counted value to a strobe signal generating circuit (31 - 3n). The strobe signal generating circuit (31 - 3n) supplies a strobe signal (STB) to a radio unit of the radio communication apparatus when a preset value coincides with the counted value of the timer circuit (20). Thus, since the strobe signal is generated without the intervention by a control circuit made up of a CPU (10) or the like, it can be output in strict timing.

Abstract: For the purpose of locating marking elements (7) in a pile (S) of labels and pushing these elements upwards, there is a detector arrangement (12) and an ejecting element (13), both of which are fixed to a carrier (20). Said carrier is connected to a traction element (21) which can be driven in rotation. Starting up a drive motor (24) causes the carrier (20) to be moved along the underside of the pile (S). As soon as the detector arrangement (12) reaches a position (26) in which it is in alignment with a marking element (7), the difference in brightness resulting thereby makes it possible to detect the presence of a marking element (7). The ejecting element (13) is then brought into an aligned position with the marking element (7) and the latter is pushed upwards by means of the ejecting element (13), causing it to jut out at the top somewhat above the pile (S). A cutting-off blade (14) which is introduced into the pile (S) behind the advanced marking element (7') is then subsequently used to separate the label bundle (16') situated in front of said marking element (7') from the remaining part of the pile (S). …<IMAGE>…

Abstract: The previously known methods, which were used in practice, for insulation testing of insulated electrical conductors which form at least one core, do not yet work satsifactorily. A method having the following features is proposed according to the invention:   - the core is moved past at least two probes which are arranged one behind the other and in each case form capacitors having a conductor piece as the opposite pole, - in this case, the probes are electrically charged in such a manner that, in the event of defects in the insulation of the core, the capacitor which is formed by the individual probe and the respective conductor piece is short-circuited by a breakdown current, - location-specific signals are in each case obtained, correlated to the feed movement of the conductor, by detecting and evaluating the breakdowns on the individual probes, - test variables for the longitudinal extent of the insulation defects are derived by logically linking the location-specific signals from the individual probes.   In the associated device, the probes form mutually insulated partial capacitors (11, 12, 13, 14), there being at least two rollers (11, 12; 13, 14) as probes which are arranged on opposite sides of the core (1), axially offset with their rotation axes at right angles to the movement direction of the core (1). <IMAGE>

Abstract: Telephone answering devices are known which have a control unit, in particular a microprocessor, to control the different device functions and the exchange of switching information with the exchanges of the connected communication system, and a magnetic tape memory and/or a digital memory to store speech signals, e.g. announcements of the called subscriber, messages of the calling subscriber. To enable improved utilisation of speech memories with a relatively low storage capacity, the telephone answering device has, in a manner known per se, a device to generate signal tones and/or intercept tones. Once the message of the calling subscriber has been recorded, a tone signal generated by the device is transmitted to the calling subscriber instead of the end announcement. <IMAGE>

Abstract: A refrigerated superconductive magnet is provided with six magnet cartridge radial struts supporting the magnet cartridge in the vertical (47,49) and lateral (51,52,53,54) directions. The struts are positioned such that two lateral struts (e.g. 51,52) on each end of the magnet cartridge react against the contact force of the cryocooler cold head and support half of the vertical (gravitational) load of the magnet cartridge (17). Two vertical struts (47,49) support the other half of the vertical load. The vertical struts pivot to allow the cartridge axial centerline to shrink towards the cryocooler (31) interface during cool down. The strut attachment points have been located near the horizontal midplane in order to minimize the sag of the magnet cartridge due to its own weight.

Abstract: In a video image processing apparatus, an analogue video image is converted to a binary value by calculating (5, 6) threshold values of respective neurons and coupling coefficients of respective synapses of a neural network circuit (3) on the basis of the input analogue video image and a predetermined function. This can be done by arranging that a difference component E between the input analogue video image and the binary value image is defined as :     where a is the coefficient, µ (i)  is the value which results from converting the input analogue video image into the binary value, P (i ,  j)  is the value obtained from the function, and ĝ (i)  is the value obtained from the function and the input analogue video image. The function is preferably a frequency characteristic of a human's eyes. The input analogue video image may be a computer hologram, and then the function is made a window function which indicates a range of a desired video image in a reproduced image which results from Fourier-transforming the computer hologram.

Abstract: An integrated circuit having a normal operating mode and a special operating mode, such as a special test mode, is disclosed. The special test mode is enabled by a series of signals, such as overvoltage excursions at a terminal, rather than by a single such excursion, so that it is less likely that the special test mode is entered inadvertently, such as due to noise or power-down and power-up of the device. The circuit for enabling the test mode includes a series of D-type flip-flops, each of which are clocked upon detection of the overvoltage condition together with a particular logic level applied at another terminal; multiple series of flip-flops may be provided for multiple special test modes. Additional features include the provision of a power-on reset circuit which locks out the entry into the test mode during power-up of the device. Acknowledgement of the entry into test mode is provided by the presentation of a low impedance at output terminals while the device is not enabled; chip enable of the device causes the device to exit the test mode. Once in test mode, the output enable terminal of the device can provide a chip enable function.

Abstract: A high speed, synchronous, packet-switched inter-chip bus apparatus and method for transferring data between multiple system buses and a cache controller. In the preferred embodiment, the bus connects a cache controller client within the external cache of a processor to a plurality of bus watcher clients, each of which is coupled to a separate system bus. The bus allows the cache controller to provide independent processor-side access to the cache and allows the bus watchers to handle functions related to bus-snooping. An arbiter is employed to allow the bus to be multiplexed between the bus watchers and cache controller. Flow control mechanisms are also employed to ensure that queues receiving packets or arbitration requests over the bus never overflow. A default grantee mechanism is employed to minimize the arbitration latency due to a request for the bus when the bus is idle.
