Patent DE-3933846-A1 (DE)
Title: Interconnecting computers by parallel bus - carrying control-data, address and data, clock-generator, control-logic circuit, comparator, register, fifo-register and multiplexer
Inventor: HOGNALAND INGVAR
IPC: H04L12/42
Filed: 1989-10-10
Abstract: A clock-generator (1) produces clock-pulses (2) in parallel to the computers.  Each computer has two neighbouring computers  and, for each clock-pulse (2), receives in parallel a fixed number of bits from one of the neighbouring computers and for each clock-pulse can transfer the same number of bits in parallel to the other neighbouring computer. The control of the data-transfer in each computer is arranged so that a control-logic circuit (5) decides, based on its own status and the received information, whether the received data should be retained. At the same time that the control-logic (5) decides if the received data should be retained, it also decides before the next clock-pulse (2) whether the received data (6,12,13) or the data (11,12,13) should be transferred to the next neighbouring computer (3). USE/ADVANTAGE - Very fast data-transfer between computers achieved by simple means with several computers being able to transfer data simultaneously.

Title: Forming press for joining components
Inventor: GRUND ANNEROSE DIPL ING
IPC: F16B5/04
Filed: 1989-11-07

Title: Disposal of asbestos containing material is removed from its supporting substrate by high pressure water jets and put in receptacle, together with water and heated furnace for converting into harmless form
Inventor: DIETER JOHANNES
IPC: B09B3/00
Filed: 1990-11-07
Abstract: Material containing asbestos is disposed of in a safe way which is also harmless to the environment. The asbestos containing material is removed from its supporting substrate by high pressure water jets. The still moist mass of material, together with the water from the jets is caught in a receptacle. At this stage some of the moisture may be removed. The mixture is then loaded into a furnace and raised to a temperature at which the asbestos material, which consists mainly of mineral crocidolite and olivin, is transformed into a physilogical harmless crystalline form consisting mainly of forsterite. After being cooled the modified mixture can be safety deposited on a refuse dump.

Title: Pulverisation system for coal-fired boiler - has set of passages to recirculate coarse particles
Inventor: STROEER KURT DIPL ING
IPC: B02C13/13
Filed: 1991-02-22
Abstract: A boiler (2), which is fired with pulverised coal has three burners (21, 22, 24) with each burner being supplied with coal of a different particle size. The pulverised coal is delivered to a fan with an impeller (3) which generates a stream of air which carries the coal particles in suspension. The outlet ducts from the fan are so arranged that the finer particles flow through the ducts (26, 28) while the coarse particles flow through the duct (23). Particles which are too coarse for the burners are deflected back to the impeller (3) where they are further pulverised to produce finer particles before flowing to the burners. USE/ADVANTAGE - Coal pulverisation system which retreats coarse particles.

Abstract: A method is disclosed for controlling the speeds of successive vehicles (Z1, Z2) on a section of rail equipped with continuous automatic train running control (LZB). The specification of an imaginary stopping point (HP) of the front vehicle (Z1) as an additional destination makes it possible for two braking curves (1, 2) to be calculated for the respective following vehicle (Z2), one of these curves being based on the rapid braking deceleration of the following vehicle and having as destination the current location (P2) of the rear of the vehicle ahead, the other being based on the operational braking deceleration of the following vehicle and having as destination the imaginary stopping point (HP) of the rear of the vehicle ahead. The following vehicle utilises the respectively more restrictive braking curve as the travel curve. The calculation of the braking curve and the minimum selection can take place either on the following vehicle or in the control centre of the continuous automatic train running control. The method increases the utilisation rate of rail routes possible until now by approximately 30%. <IMAGE>

Title: Millimetre wavelength frequency division e.g. for vehicle sensing system - using auxiliary oscillator, N-harmonic mixer and frequency divider to produce N-divided frequency
Inventor: BUECHLER JOSEF DR ING
IPC: H03L7/185
Filed: 1991-04-12
Abstract: An intermediate frequency, fOSZ - n(f1), is produced by mixing the primary oscillator (5) frequency, fOSZ, with either an n-multiplied output from an intermediate frequency (i.f) oscillator (1) using a conventional mixer, or with the i.f. oscillator output using an n-mulitple harmonic mixer (4a). The latter mixes the primary oscillator frequency with the n-multiple harmonics of the i.f. oscillator output to produce the intermediate frequency. This intermediate frequency is then amplified (2) and passed to a frequency divider (6), where the fOSZ - n(f1) signal is divided by the harmonic multiple/frequency multiplier factor, n, to give a divided i.f. frequency, (fOSZ/n) - f1. This divided frequency is then mixed with the i.f. oscillator output, f1, in a mixer (7), to obtain the n-divided original frequency, fOSZ/n. ADVANTAGE - I.f. signal is derived without using feedback amplification loopl and frequency division factor (n) is not dependent on i.f. oscillator frequency.

IPC: H04H20/00
Filed: 1991-06-05
Abstract: A process is disclosed for processing and reproducing received, digitally coded audio data, as well as a radio receiver for digital audio broadcast (DAB). In the case of digital broadcasting means, for example digital audio broadcast (DAB), reception is abruptly interrupted at the edge of the propagation area, i.e. when the broadcasting channel reached the limits of its capacity. It is proposed in the case of digital broadcasting systems to obtain a so-called "graceful degradation". According to the invention, an artificial "graceful degradation" is obtained by artificially modifying the reproduction signal depending on the quality of broadcast or reception when an adjusted threshold value for the quality of broadcast or reception is not reached. The invention is useful for digital radio receivers, in particular DAB receivers.

The piston (20) in the cylinder supports the movable mould during the pressing process. After the process, the piston draws the mould off the pressed material. USE/ADVANTAGE - Press for powderised material operates without expensive hydraulic elements, which may be liable to failure, but retaining good adjustment etc.

IPC: C02F1/52
Filed: 1991-11-07
Abstract: The description relates to a process for flocculating a finely devided organic or inorganic synthetic substance from an aqueous liquid in which a multivalent electrolyte, a calcium compound and a carbon compound which, with calcium, gives a reaction product which is difficult to dissolve are added to the liquid. Ferric salts, burnt lime and CO2 are preferably used. It is thus possible to clear mainly waste water from stabilised dispersions of fully synthetic polymers.
