Title: Method and arrangement for the configuration of a control system for track installations
IPC: B61L25/08
Filed: 1990-07-04
Abstract: A method and arrangement for the configuration of a control system for track installations corresponding to a track configuration composed of several track elements, such as sets of points, signals, track sections or the like, connected to one another, is proposed. Each track element has associated with it a system component of the control system. One of the system components of the control system is assigned a digital identification code. Each of the system components detects which system components are associated with the track element, of adjacent track elements, associated with said component. The aforesaid system component assigns a name to the system components of the adjacent track elements of its track element. The system components named in this way behave similarly. An automatic self-configuration of a decentralised control system thus takes place in accordance with the track configuration. <IMAGE>

Title: Flexible multiplex system
IPC: H04J3/16
Filed: 1990-12-06
Abstract: The multiplex device of the flexible multiplex system is used for dividing a multiplex channel into several subscriber channels (CH1 to CH6). Each data input (E1 to E6) is associated with one serial/parallel converter (SPU1 to SPU6), the parallel outputs of which are connected via a data bus (DBM) to a parallel/serial converter (PSU) which outputs at its output the multiplex signal (MS). A memory control (STS) specifies the number of subscriber channels (CH1 to CH6) and their data rate. It also provides for the insertion of the frame alignment words (SO1, SO2) and of the signalling words (DO1 to DO6) at the correct time. The demultiplex device is constructed to correspond to the multiplex device. <IMAGE>

Abstract: In a multicavity klystron amplifier, the drift-tube 
bore is larger (46) in proportion to the beam size (10)

size (22) at the gaps (28). This decreases the space-­
charge wavelength so that the overall physical length of 
the klystron is shortened.

Title: Real-time vehicle simulation
IPC: G06F19/00
Filed: 1990-06-05
Abstract: An automobile-simulation graphics display D is 
generated in sequential frames (1-7) in 
dependence upon positions and movements of driver 
controls 12, 14, 16, 18, signalled by transducers 22. 
Non-linear suspension and chassis models 26 and 28 
operate in conjunction with a road model 34, to derive 
from the transducer outputs, representation of a 
current vehicle-position (including orientation). A 
prediction of vehicle-position five display-frames in 
the future is made from this representation by a 
chassis prediction model 36 using drive-train and 
steering and control extrapolations derived by units 30 
and 32 from the transducer outputs. The five-frame 
lead compensates for delay in computing, processing 
data for generation of the image display, and display 
of the image (54, 56, 58).

Title: Method for manufacture of sandwich type moulded articles and panels, mainly of textile fiber structures
IPC: B29C33/38
Filed: 1991-10-28
Abstract: The subject of the invention is a method for manufacture of sandwich-type moulded articles and panels, mainly of textile fibre structures, which contain fibres having different thermal properties, by pressure, heat and moist hot air, using moulds, which have a greatest-possible, uniform porosity, to press panels and moulded articles with a sandwich structure and cool them in the same cycle, the moist hot air and a special design of the mould causing a positive pressure to be achieved in the mould and consequently in the fibre structure, which pressure makes the outer sides in particular of the fibre mats set largely evenly on the mould surfaces, the inner structure of the moulded articles or panels then having a lower density. By using this method, the weights of moulded articles and panels to be described can be reduced, which is of decisive significance in terms of price and acceptance on the market for energy reasons alone. Furthermore, by using fibre systems comprising the same polymer, reuse is largely possible, since then it is possible to dispense with binder systems of a different type.

Title: A semiconductor integrated circuit
IPC: G01R31/28
Filed: 1991-11-11
Abstract: An electronic circuit for the detection of required operational speed of one or more integrated circuit semiconductor chips is used in conjunction with an off-the-shelf integrated circuit tester. The tester provides timing, control and a display. Each of the integrated circuit semiconductor chips is provided with a ring oscillator circuit for generating a series of pulses, timed by the tester for a fixed period of time. A counter, formed in each of the semiconductor chips counts the number of pulses generated during the fixed period of time. A number, generated in the tester, indicative of a required speed of operation is set in a latch assembly that is formed in each of the semiconductor chips. A comparator, also formed in each of the semiconductor chips, compares the contents of the latch with the contents of the counter and if the contents of the counter is equal to or larger than the contents of the latch, the tested semiconductor chip is acceptable. A display in the tester indicates the result. If the speed of operation is very high, then the numher indicative of a required speed of operation is divided by, for example, two. The output of the oscillator is also divided by two so that the size of the counter and the latch is not exceeded.
