Patent DE-3267145-D1 (DE)
Title: A method of and apparatus for, generating a unique index mark from the commutation signal of a d.c. brushless motor
Inventor: RUXTON DAVID SCOTT
IPC: G11B27/10
Filed: 1982-06-22
Granted: 1985-12-05
Abstract: A unique index mark is provided to avoid errors in addressing a memory location on a disk surface by correlating the commutation signal from a d.c. motor with a synchronizing signal present on one or more discrete tracks of the disk. The proportion of the synchronizing signals on one track depends on the number of phases of the d.c. motor although typically with a 2-phase motor one-half of the track contains the synchronizing signal, the other half of the track being erased. The commutation signals and the synchronizing signals are correlated using a microprocessor and a flip-flop. A sensing head looks for a synchronizing signal which is typically 10 individual data blocks of short duration. The detected blocks are counted in each half revolution of the disk, timed from the index edge and comparing the counts in successive half-revolutions in a comparator over several disk revolutions. The microprocesser then identifies from the comparator output the half-revolution of the disk in which the synchronizing signal was recorded. The microprocessor receives the output of the comparator and forces the output of the flip-flop hi setting an initial condition. Thereafter the microprocessor ensures that the flip-flop output is always correlated with the synchronizing signal thereby producing a unique index mark.

Title: Method of reboiling by vapour recompression
Inventor: GOURLIA JEAN-PAUL
IPC: C10G7/02
Filed: 1982-11-30
Granted: 1985-12-12
Abstract: This invention relates to distillation in pressurized columns and provides a process for reboiling such columns. The column 1 working at a pressure of 11 bar is fed with a mixture of hydrocarbons preheated in exchangers 2a and 2b to about 130 DEG  C. A part of the bottom is withdrawn, then expanded by means of an expansion valve 5 to 2.5 bar in an expansion balloon flask 6 where the phases are separated. The vapor phase is compressed in a compressor 7 to the pressure of the column and reinjected at the bottom of the column, whereas the liquid phase is removed. With the process, energy can be saved in pressurized distillation columns, for example in petrol stabilization columns.

Title: Device for processing non-associated signalization for an automatic tdm switching system
Inventor: FAVREL JEAN-PAUL
IPC: H04Q11/04
Filed: 1983-12-01
Granted: 1987-09-03
Abstract: The invention concerns exchanges switching telephone traffic, and in particular digital exchanges which have tie-lines passing therethrough. The exchange comprises control units (UC) and terminal units (UT) which are microprocessor controlled and which are connected to a switching network (RCX) by two-way multiplex links (MU). Some of the terminal units are connected to handle respective PCM junctions. At least one of the terminal units is a mixer and separator unit (UTB) which receives the signalling channels and in particular the signalling channels associated with the tie lines. This mixer and separator unit serves to forward signalling channel information for the tie lines. The terminal units connected to PCM junctions which include tie lines send the tie line signalling to the mixer and separator terminal unit, and also receive said signalling from said mixer and separator unit for onward transmission over a destination PCM junction.
Patent DE-3377889-D1 (DE)
Title: Ground/working implement depth control system
Inventor: WIEGARDT GORDON K
IPC: A01B63/111
Filed: 1983-11-18
Granted: 1988-10-13
Abstract: The working depth of an implement attached to the 3-point hitch of a tractor is normally controlled by a draft load error signal formed as the difference between a load set point signal and an actual load signal provided by a draft sensor. For lowering the implement into the ground and raising it a depth position lever (50) actuates a transducer (54) to provide a position set point signal A(3) which is compared with an actual position signal from another transducer to form a position error signal. A large position error takes precedence over a smaller load error. In order to provide the load set point signal without the need for a separate lever, a swith (58, 60) is mounted on the lever (50) and, when depressed, causes the draft load set point signal to increase up to the desired value as the implement is lowered into the ground by pushing the lever (50) forwards.

Title: Device for arc welding, particularly for submerged arc welding with one or two consumable electrodes
Inventor: DILTHEY ULRICH DR ING
IPC: B23K9/12
Filed: 1984-06-16
Granted: 1987-01-15
Abstract: A device for arc welding having one or more fusible electrodes (15) which are in each case supplied from an alternating-current source (14) having a falling characteristic. The feed rate of the electrode (15) is regulated for constant arc length as a function of the arc voltage. Via a further regulator (37), the deposition efficiency is regulated by supplying the regulator (37) with the feed rate as actual value and changing the welding-current intensity as a function of this value. The change in welding-current intensity leads to an increase or decrease in arc length which, in turn, is compensated via the first regulator by changing the feed rate.

Granted: 1989-07-06
Abstract: The ice warning system comprises a diaphragm (2) set into vibration at one of its frequencies of resonance by a piezoelectric cell (3). The diaphragm (2) is thermically coupled to a metallic plate (4) alternately cooled and heated respectively below and above the ambient temperature (Tu) by Peltier elements (8) connected to a reversible DC current generator (11). A microprocessor (12) measures the variation of the resonance frequency caused by a deposit of ice on the diaphragm (2) during the cooling or heating periods and delivers an alarm signal whenever any variation of the frequency reaches and/or exceeds a predetermined value. The microprocessor (12) controls also the period, the magnitude and the direction of flow of the current from the current generator (11) in dependence on the ambient temperature and the temperature of the diaphragm. The ice warning system is preferably utilized in the aeronautical field for signaling the likelihood of natural ice formation on the engines and the wings of aircrafts.
