Patent EP-0330742-A2 (EP)
Inventor: BRAEMERT PETER
IPC: B61D17/22
Filed: 1988-11-24
Abstract: The subject of the invention is a communication device for railway carriages which consists of a communication gangway (5) and a communication protection device (36, 2, 3) arranged in a tunnel-like manner above the latter. The device is constructed in such a way that even in the case of extreme pressure differences between the outside and the inside the interior is well protected from exterior influences. The tunnel-shaped communication protection consists of an inner end frame (36) for attachment to one of two railway carriages which are to be coupled together, an outer end frame (3) for cooperating with the outer end frame of the communication device of the other of the two railway carriages to be coupled to one another and of an elastic element, in particular a bellows (2) between the two end frames (36, 3). The outer end frame (3) is suspended directly on one of the two railway carriages by means of springs (4a) which exert a force directed outwards onto the outer end frame (3). The communication gangway is constructed in two parts, of which an inner part (9) is attached to one of the railway carriages to be coupled to one another and the other outer part (6a) is displaceably supported at the rear end on the inner part, is connected to the front end with the outer end frame (3) and ends in the same vertical transverse plane as the outer end frame. The outer end frame is provided with a support face (4, 4b) so that, in the case of two railway carriages coupled to one another, the communication gangways and the communication protection devices of both communication devices rest against one another at the end sides and are held resting against one another by the springs (4a) so that no connecting means are required, but the connecting region between the two communication devices is nevertheless sealed even if admissible lateral displacements occur between the two communication devices. Communication protection device and gangway are sealed from one another. The outer end frame (3) is of tunnel-shaped construction and its relatively long side walls have flaps in the front lower region which close off openings into which the communication gangway of a second railway carriage coupled to the first railway carriage can dip when going round a bend if this gangway moves away from the gangway of the communication device in such a way that it dips into the communication device of the first railway carriage as a plate and rests on the communication gangway of said carriage.

Abstract: A security system for monitoring and detecting security breaches in a home comprises a central monitor and a plurality of remote sensors for one or more of fire, smoke, intrusion, appliance operation and the like. Each of the sensors has a transmitter for transmitting an electronic message when the sensor goes into an alarm condition. The central monitor has a receiver to receive the electronic messages. An electronic microprocessor system decodes the received electronic message and takes the necessary course of action in accordance with a programmable scheme retained in electronic memory of the microprocessor system. The central monitor has a speech synthesizer responding to inputs from the microprocessor system. A keyboard is provided on the central monitor for allowing a user to interact with the security system. The microprocessor system is programmable via the keyboard to permit the user to customize the programmable scheme to render it unique to the user. The microprocessor system actuates the speech synthesizer to synthesize predetermined messages in response to input from the keyboard and in accordance with the programmable scheme based on received electronic messages from the transmitters. The microprocessor system is capable of checking data as it is entered by the keyboard against what is required by the programmable scheme. This checking system permits the security system to announce an error message should the entered data be incorrect. The security system incudes a device for not only announcing an alarm condition and sounding the siren, but also a device for dialling a predetermined series of telephone numbers to alert others of the security breach in the monitored premises.

Abstract: In a computer image generation system, as a viewpoint approaches a surface of an object and is closer than a predetermined threshold distance from the surface, a texture pattern obtained from cell data becomes fuzzy, and may not provide adequate motion cues for training, such as piloting an airplane. In accordance with the present invention, random data is provided (13,14) at a predetermined derived level of detail (M=0) for combining (25) with cell data (LOD(M)) to define the surface including texture of the object when the object is closer to the viewpoint than the threshold distance. The apparatus may be readily retrofitted into an existing system.

Abstract: A color liquid crystal display device comprising light shielding layers (4) and color filters (3) on the inner surface of a cell, wherein similar light shielding layers and color filters are disposed also in a peripheral region outside of a display region which is equipped with groups of striped row and column electrodes (10) opposed mutually to form pixels for display. The respective patterns of the light shielding layers and the color filters are the same in both the display region and the peripheral region. A liquid crystal layer formed in the display device has a twist angle of 160° to 300°, and a retardation compensator composed of a film is superposed on such layer so as to compensate the elliptical polarization. And a non-selective voltage is applied continuously to the scanning electrodes in the peripheral region so as to maintain the peripheral pixels in a light-shielded state, thereby rendering the display easier to be seen. Furthermore, due to overlaps of the color filters and the light shielding layers in both the display region and the peripheral region, the gap between the substrates (8) is retained substantially uniform to minimize the nonuniformity of the backgroud color.

Abstract: In a ripple-control receiver, the input signal limited by a low-pass filter is modulated with a control frequency (SF) onto a modulation frequency (MF) and is raised to an intermediate frequency position. A sideband (SB) is selected using a first band-pass filter and is shifted back with a demodulation frequency (DF). A second band-pass filter finally limits the input signal for analysis. By varying the modulation frequency (MF), the ripple-control receiver can be matched to different control frequencies (SF). The analyser from the intermediate frequency range remains the same in each case. If the input signal is shifted back below the original control frequency (SF) by the demodulation, it is easier to fulfil the requirements for quality and stability of the filters than with a direct processing without intermediate frequency (ZF). <IMAGE>

     wherein R' is aliphatic, aromatic, alkoxy, or combinations thereof, having from 1 to 6 carbon atoms, or halogenated derivatives thereof, or hydrogen; and R 2  is aliphatic, aromatic, alkylhydroxyl, or combinations thereof, having from 1 to 18 carbon atoms, or halogenated derivatives thereof; or hydrocarbyl ether such as alkoxyalkyl, phenoxyaryl, phenoxyalkyl, or combinations thereof, having from 1 to 18 carbon atoms or substituted halogen, oxygen, nitrogen or sulfur derivatives thereof, wherein the total number of atoms in R 2  is from about 3 to about 80. Optionally, an acrylate monomer which acts as a physical property enhancer is added. Improvements are achieved in the oil resistance of the thermoplastic elastomer and lead to an elastomer which can be used where oil resistance is important, such as in certain types of shoe soles, gaskets, and pipe liners. These improvements are balanced against compression set and brittleness characteristics.
