Patent DE-3804794-A1 (DE)
Inventor: RIPPEL ROBERT DR
IPC: C07D333/48
Filed: 1988-02-16
Abstract: Thiophene derivatives with an optionally substituted amino group on the thiophene ring are prepared by dehydrogenation of dihydrothiophenes which are substituted in the same manner as the desired thiophene derivatives, using H2O2, the dihydrothiophenes being reacted in a first reaction step with H2O2 in neutral medium to give the corresponding sulphoxides, and, in the second reaction step, these are then rearranged with acid to give the thiophene derivatives. The dihydrothiophene-1-oxides which are formed in this process as intermediates are novel compounds. They, and equally the thiophene derivatives obtained from them by rearrangement with acid, are intermediates mainly in the crop protection agent sector and pharmaceutical sector.

Title: Method for directly setting up telecommunications connections, in particular telephone connections, on workstations or answering stations of multi-user dealing room systems
Inventor: HUTT JUN HANS-ULRICH
IPC: H04M3/60
Filed: 1988-03-04
Abstract: In multi-user dealing room systems with direct access to a multiplicity of external lines, permanent allocation of a destination telephone number to an external line is intended to be able to be set up in simple fashion. With designated seizure of one of these external lines through simple actuation of an assigned operating element, the permanently allocated destination telephone number is then automatically selected. The destination telephone numbers are allocated to external lines by means of a specific operating procedure in that a line number, a destination designation and a destination telephone number are entered, this information being stored in a row in a main memory of the switching system, which row is assigned to the external line concerned. On completion of this procedure, the destination telephone number is automatically selected when the line is seized by touching or actuating the operating element assigned to this external line. This produces quasi-dedicated circuits, whose sub-areas which are assigned for operation are clearly disposed on a monitor so that operation is significantly simplified.

Patent DE-3823309-A1 (DE)
Inventor: SUGAO KEIZO
IPC: C23C26/02
Filed: 1988-07-09
Abstract: Metal pipes coated with tin or tin based alloy are manufactured by inserting tin or tin based coating material eg as a wire, thin sheets or powder into the metal pipe, raising the temperature rapidly to over 1000 DEG C; eg by using a high frequency furnace which maybe set at a frequency in excess of 10 KHz in a non-active, or non-oxide atmospheric gas, or in a reducing gas, to melt the inserted material and thereby coat the entire interior wall of the metal pipe with tin or tin based alloy, and, then, to cool it at a high rate of cooling. The tin based alloy may be a tin-zinc alloy or a tin-lead alloy. The metal pipe may be of carbon steel or may be a double-walled pipe manufactured from steel plated on one or both sides with copper plate. According to this method a uniform coating is formed in the interior wall of the metal pipe, without giving rise to blockage of the interior of the pip and segregation of the joint section when the pip is double-walled or to the non-formation of coating. Improved corrosion resistance also results.

Title: Detonation transmitter for shaped charges
Inventor: SASSMANNSHAUSEN ULRICH DR
IPC: F42C19/08
Filed: 1988-12-24
Abstract: The present invention relates to detonation transmitters in shaped charges. These detonation transmitters are detonated at points on their axis in the preferred embodiment and transmit the detonation uniformly to the detonation booster or to the warhead; this results in uniform propagation of the detonation front within the booster charge, so that the warhead can be detonated uniformly in the annular shape. This also applies when the detonation booster is omitted and the detonation transmitter rests directly against the warhead. According to the invention, the detonation transmitter is designed as a truncated cone (frustrom). The axis of the truncated cone in the shaped charge is such that it is identical to the axis of the shaped charge. The angles enclosed by the tips of the truncated cone are preferably between 60 and 100@. The double cone may also be a double truncated cone, one of whose base surfaces faces the barrier while its second base surface rests against the detonation channel originating from the detonator.

Title: Method for handling connections in communications switching systems in an integrated services network (ISDN)
Inventor: THEIS HARALD DIPL ING
IPC: H04M3/436
Filed: 1989-01-23
Abstract: It is intended that a subscriber be able to determine for himself the way in which calls are to reach him, these calls being selectable according to their origin. It is furthermore intended to be possible to specify that specific calls are rejected. In the communications switching system, a memory is provided which has destination areas assigned to connections which are to be called. Identifiers of possible callers and connection identifiers assigned to these callers are stored therein. The connection identifiers serve to specify the way in which the identified incoming connections are offered to the required subscriber or are rejected. A comparator serves to identify whether identifiers are recorded for a caller, the connection concerned being handled in a specific manner depending on the recorded connection identifier. With the information entered into the memory by the subscriber himself or from a central station, specific connections can be switched through with prioritisation or can be announced in a special way, and the rejection of unwanted callers can also be effected.

Title: Spindle drive control - compensates for slip through timed measurements to correct nominal value in force
Inventor: ERNI MARKUS
IPC: D01H1/32
Filed: 1989-07-04
Abstract: To control the drive to an operating textile machine component, partic. a ring spinner with a number of spindles with adjusted nominal value speeds, the slip is established at the powered unit at least at times. A correction is applied to the nominal value to compensate for any slip detected. Where a common drive powers a number of units, their rotary speeds are measured and compared with a nominal value, and any slip between the common drive and the powered units is compensated by an appropriate correction, taking into account any gearing redn. between the drive and the units. The corrected nominal value is used as a guide value for automatic correction to all the units powered by the common drive, and remains in force until the slip is measured again, and the gearing is adjusted in the transmission train according to the new value. The correction is applied to the supply current to the motor, where the frequency determines the motor speed.  The nominal value for each spindle in the ring spinner is taken according to the yarn delivery speed and the required yarn twist. The electronic drive control (14) has a correction unit (16) incorporating a pre-set nominal value (nSoll) which, according to the measured slip between the drive and the driven components (12), can generate a corrected nominal value (n'Soll).  With a common drive (18) for a number of powered components (12), the electronic drive control (14) has a comparator (20) to compare the corrected nominal value (n'Soll) with a signal from each station (12) representing its rotary speed.  The comparator (20) generates a signal (Y) to control the common drive speed according to the comparison calculation, and the setting unit (16) gives the compensation for slip between the common drive and the powered units. ADVANTAGE - The slip effect can be established and corrected.
