Title: New alpha-sulpho carbonyl cpds. useful as surfactants - prepd. by sulphonating higher aldehyde or ketone with sulphur tri:oxide
Inventor: RATHS HANS-CHRISTIAN DR
IPC: C09K23/08
Filed: 1992-06-24
Abstract: New alpha-sulpho carbonyl cpds. (I) are obtd. by reacting an aldehyde or ketone (II) with gaseous SO3 and neutralising the prod. with an aq. base. (II) has a m.pt. below 90 deg. C and is of formula R1COR2, where R1=5-22C alkyl and R2=H or 5-22C alkyl. Pref. (II) is a ketone produced by pyrolysis of a 6-22C fatty acid alkaline earth metal salt. Sulphonation is effected at 40-98 deg. C with a (II):SO3 molar ratio of 1:0.1-2.4, esp. in a continuous falling-film reactor. Neutralisation is effected with a 5-55% aq. soln. of an alkali metal hydroxide, alkaline earth metal oxide or hydroxide, NH4OH, mono-, di- or tri(2-4C)alkanolamine or mono-, di- or tri(1-4C)alkylamine. USE - (I) have surface-active properties, suppress foaming of anionic surfactants in aq. systems, and promote the wetting of solid surfaces and the emulsification of oil and water.

Patent DE-4222204-A1 (DE)
Title: Metal castings prodn. - using same green sand for mould boxes and cores, to avoid separate prepn., processes and damping of used core sand
Inventor: HUMBERG JUN FRANZ
IPC: B22C9/10
Filed: 1992-07-07
Abstract: In casting hollow metal parts the same green sand contg. water is used to produce both the mould and core. During the assembly of the mould and core, the latter remains in a part of the core box as the mould is positioned over it. After the core prodn., the lower mould box is rotated so that it is open in a downward direction. It is then positioned over the core before the whole assembly is rotated into the upright position and the core box removed before the upper mould box is set in position on top of the core and lower mould box. ADVANTAGE - Avoids the problem of having to dump the used core sand as in the prior art. Also two sand prepn. processes are avoided.

Title: Electrical processing of vacuum pressure information for vacuum unit - comparing each value measured before connection to vacuum aperture with previously stored dual level value below maximum measured value
Inventor: SUGANO SHIGERU
IPC: G01D7/00
Filed: 1992-09-07
Abstract: The data processing method involves detecting the pressure information, digitally displaying and storing a desired pressure below the maximum detected value, digitising each pressure value measured before an aperture connected to a vacuum opening, comparing it with the stored desired pressure, and displaying a fault or failure point accordingly. The stored desired pressure value has two levels. One is lower than the maximum vacuum pressure level which is defined as lower than the pressure to be detected. The second is lower than the first by a pressure selected to prevent a hunting effect. ADVANTAGE - Enables simple adjustment of desired pressure level and fault position indication.

Title: Device for measurement transmission between sensors and a monitoring unit
Inventor: JAHNK VOLKER DIPL ING
IPC: G01F15/06
Filed: 1993-04-20
Abstract: So that the measurement values (measured values) received by sensors (S1; ...Sn) can be transmitted in a simple and reliable manner, optocouplers (U117; U117A; U117B; U117C) are connected via an operational amplifier (N116A) and a low-pass filter (N166B; R36; R37; C59; C60) and a SYNC line (SYNC) to a microprocessor unit (MP) and via a power supply (V75; V76; V77; V78, V93; V94; V95; V96; R43, R44, C64) to a bus system (BUS). In this way, it is possible, by means of the currents which are supplied by the operational amplifier (116) which operates as a voltage-controlled power source, to trigger a modulation current at the outputs of the power supply (V75; V76; V77; V78; V93; V94; V95; V96; R43; R44; C64) as a result of an applied voltage (UTAX), so that measurement values supplied by the sensors (S1; ...Sn) connected to the microprocessor unit (MP) can be transmitted to the bus system (BUS) without potential. <IMAGE>

Title: Control device for motor vehicle differentials for improving the traction and driving stability
Inventor: INGELHEIM PETER
IPC: B60T8/40
Filed: 1993-05-05
Abstract: The invention relates to a control device for the differentials of motor vehicles for improving the traction and driving stability. In this, using two special planetary transmissions on the front and rear axle of the vehicle the relative twisting of the lefthand and righthand wheel of the axle is converted into a rotation of the third shaft of the planetary transmission. Since the speeds of rotation of the third transmission shafts differ by less than 4% even when cornering, the said two shafts can be connected non-positively, with the result that even when cornering the slip of one drive wheel is prevented without any control intervention. If a non-positive connection in the form of a hydraulic transmission is selected, active control intervention is possible for further improvement of the driving stability and a simplification of the anti-lock brake system.

Title: Oscillating welding torch, in particular for inert-gas welding on automatic welding machines
Inventor: SCHUELER DIERK-HENNING
IPC: B23K9/16
Filed: 1993-05-12
Abstract: In oscillating welding torches which realise the oscillating movement of the torch nozzle by electromagnetic coils directly at the universally swivellable torch segment, it has been found that the magnetic fields which can be produced by conventional coils are not strong enough to attract the torch neck of the torch segment without delay or inaccuracies. The novel oscillating welding torch is intended to permit the swivelling movement of the torch neck from the one oscillating end position into the opposite oscillating end position even over a larger air gap between the torch neck and the respective electromagnetic coil. According to the invention, a web plate 7 of ferritic material is allocated to each electromagnetic coil 6. The web plate 7 is fastened to the torch neck 4 of the torch segment 2, points with its free end towards the coil centre and is designed as a magnetically movable armature of the coil 6. <IMAGE>

Abstract: The invention relates to an X-ray examination unit with a unit comprising a bearing plate (2) whose height can be adjusted on a base (5) and an image intensifier (3) adjustably mounted on the base (5). According to the invention, the image intensifier (3) is adjusted from a recording position into a parking position in order to reach a lower position of the bearing plate (2). The image intensifier (3) can be horizontally aligned in the parking position or else it can be located outside the range of the bearing plate (2). The advantage of this is that the bearing plate (2) can thereby have a lower height. <IMAGE>
