Title: Process for producing supergrade (premium) petrol from butanes and/or fractions which contain four carbon atoms and originate from catalytic cracking or reforming
Inventor: JUGUIN BERNARD
IPC: C10L1/06
Filed: 1987-09-15
Abstract: In the process according to the invention for producing supergrade petrol from a hydrocarbon fraction which contains four carbon atoms and originates from a catalytic reformer or cracker, the batch is subjected to a dehydrogenation reaction of a zone 7, the efflux taken off from the zone 7 is conducted into a zone 10 for the selective oligomerisation of the isobutene; the mixture obtained at the outlet of the zone 10 is fractionated into:   - a hydrogen-containing light gas which is taken off from column 12 and partly recycled to zone 7, - a propane-containing gas mixture which is taken off from column 17,   - a supergrade petrol fraction which is taken off from column 20 through line 21 and fed to the supergrade petrol collection vessel 22 and - a fraction containing n-butane, isobutane and n-butenes which is passed to an alkylation zone 24 via line 23.   The efflux taken off from the zone 24 is fractionated in column 27 into an n-butane/isobutane fraction, which is passed into the zone 7 through line 28, and an alkylate, which represents a supergrade petrol fraction, which is fed through line 30 to the supergrade petrol collection vessel 22. A mixture of the two fractions fed to the supergrade petrol collection vessel is obtained through line 31, which mixture represents the sought-after supergrade petrol. <IMAGE>

Title: Spot-type disc brake
Inventor: WEILER ROLF
IPC: F16D65/14
Filed: 1988-02-10
Abstract: The invention relates to a spot-type disc brake in which the brake pads are guided on the side walls of a well and the contact surface for the brake pads is formed from a metal different from that of the housing. With the use of the known well plates, there is the disadvantage that, due to corrosive interaction with the well, they come away from the walls of the well and the brake pads may jam as a result. There is furthermore the disadvantage that, with the large number of adjacent components, the tolerances may be cumulative. The invention describes the use of profiled rails which are screwed to the housing in the axial direction and can be adjusted in their position in the circumferential direction of the brake disc. <IMAGE>

Patent DE-3808168-A1 (DE)
Inventor: HEATH CHESTER ASBURY
IPC: G06F12/06
Filed: 1988-03-11
Abstract: A data processing system includes a central processing unit (CPU), a main memory unit, and input/output (I/O) sockets, each adapted to receive a selected one of a plurality of different and/or similar option cards. Each card contains (or is connected to) and controls a respective peripheral device, and each card is pre-wired with an ID value corresponding to its card type. Programmable option registers on each card store parameters such as address information, priority levels, and other system resource parameters. A setup routine, during initial power-on, retrieves and stores the appropriate parameters in the I/O cards and also in socket locations in main memory, one location being assigned to each input/output socket. Each socket location is adapted to hold the parameters associated with the card inserted in its respective socket and the card ID value. That portion of main memory containing the socket locations is adapted to maintain the parameter and ID information by means of battery power when system power fails or is disconnected, i.e., a non-volatile memory portion. Subsequent power-on routines are simplified by merely transferring parameters from the memory to the card registers if the status of all the sockets has not changed since the last power-down.

Title: Radar signal processing method
Inventor: STOCK DON J R DR
IPC: G01S13/524
Filed: 1989-03-10
Abstract: For signal processing in a polarimetric radar having two receiving channels corresponding to two orthogonal received polarisations, it is proposed to subject the quadrature-demodulated video signals for each transmitted polarisation/received polarisation combination separately to identical Doppler processing operations and to feed the Doppler output signals at identical Doppler frequencies from all the separate Doppler processing operations to in each case one common polarimetric CFAR detector. The polarimetric CFAR detector checks whether, at the respective Doppler frequency, the multi-channel information items in the radar cell under test on the one hand and in the cells within a defined region on the other hand correspond or differ so greatly from one another that it is possible to deduce the presence of a target. In addition to this region CFAR, a parallel CFAR processing operation can be carried out, in an even more favourable manner, for white noise, and CFAR target detection of slowly moving targets can be carried out against fixed returns (stationary target clutter) for the Doppler output signals from the stationary-target filters.
