Title: Boiler feed water from sea water - by acid and alkali treatment, distn. and ion exchange
Inventor: HITZEL HANS ING GRAD
IPC: B01J39/04
Filed: 1980-06-20
Abstract: Prodn. of boiler feed water from sea water is carried out by (a) treating raw sea water with an acid, (b) removing CO2, (c) adjusting the pH to 6-8 by adding alkali, (d) distilling the water, (e) contacting the distillate with regenerable cation and anion exchangers, (f) regenerating the ion exchangers, and (g) recycling the regeneration effluents (contg. excess acid and alkali) for mixing with the sea water before step (d). The cation exchanger is pref. regenerated with HCl and the anion exchanger with NaOH. The distillate is pref. contacted with the ion exchangers at 20-80 deg.C. Recycle of the regeneration effluents ensures 100% utilisation of the regeneration chemicals, avoids disposal problems, and allows distillates with a higher salt content to be processed, thus allowing the distn. equipment to be simplified.

Title: Shaft torque measurement system - generating alternating magnetic field from excitation coil achieving magnetic hysteresis in saturation region
Inventor: WINTERHOFF HORST DIPL PHYS
IPC: G01L3/10
Filed: 1980-08-25
Abstract: The method of measuring torques acting on shafts involves the use of a magnetic field generated by a coil and acting axially on the shaft and contacts tapping an electrical voltage proportional to the torque from the surface of the shaft. The method uses the Wiedemann effect. An alternating magnetic field is applied. Its amplitude is so large that the magnetic hysteresis is driven into the saturation region. The method may also be used in determining the associated force. In which case the excitation coil (2) carrying an alternating current is wound around the windings of a spiral spring (20) subjected to the measurement force (k) along its longitudinal axis.

Title: Emulsion plant for heavy oil - esp. for mfg. homogeneous and stable emulsion of fuel oil and water which is fed to fuel burners
Inventor: VALDENEBRO MORANO ALBERTO
IPC: B01F3/08
Filed: 1980-08-28
Abstract: Pipe and valve are used to feed heavy oil continuously into a tank provided with a gas vent. The tank pref. also contains a serpentine coil, through which water flows without entering into contact with the oil. An electric float is pref. used to maintain a constant oil level in the tank, which pref. also has an electric resistance heater and thermostats keeping the oil and water at a constant temp. The water then flows through a filter, pump, valves and flowmeter to an emulsifier, which also receives the oil through similar equipment. The emulsified mixt. is pref. fed into a second heated tank kept at a constant temp. and used to feed the emulsion to a row of fuel burners. The combustion prods. obtd. by burning the emulsion include no residual liqs. and do not pollute the environment.

Title: Detecting moisture rising in materials by capillary action - using thermal sensors at vertical intervals to determine temp. gradient
Inventor: TENGE HANS-WERNER
IPC: G01N25/72
Filed: 1980-11-13
Abstract: Electron-optical representation of moisture rising by capillary action is porous materials or structures enables measurement data to be divided up according to superimposed disturbance. Different types of moisture damage with different causes can be differentiated. The porous material is sampled by temp. sensors at vertical intervals between 5 and 50 cm., pref. between 10 and 20 cm. The sensors provide or extract practically no heat to or from the surface. The thermal gradient is determined from the measured temp. data against distance. Regions contg. moisture due to capillary action are indicated by evaporation cooling producing a significant thermal gradient. The upper limit to which moisture has risen is indicated by a jump in temp. of between 0.4 and 2 degrees C. per 10 cm.

Title: Apparatus for transporting bottles, glasses or the like through a treatment machine
Inventor: SCHOTT HELMUT
IPC: B67C7/00
Filed: 1981-05-07
Abstract: An apparatus is proposed for transferring bottles from a filling machine to a sealing machine. In particular, the transfer of the filled, unsealed bottles and their onward transportation takes place with a complete absence of abrupt movements, so that spillage of the liquid is avoided. To this end, the apparatus is so designed that each bottle (13) is moved, with a complete absence of abrupt movement, into a receptacle (12) of a rotating transport member (11) with the aid of two guide cams (14, 19) and a stop (15) while this rotating transport member (11) is stepped forward. As a result of the apparatus according to the invention, spillage of the liquid is prevented and the bottles (13) are moved into the receptacles (12) with a complete absence of abrupt movement and with no additional movement-controlled means. <IMAGE>

Title: Process for the cleaning of squeezing rollers and squeezing roller and apparatus for carrying out the process
Inventor: BERGER JOHANNES DIPL ING
IPC: D06B23/30
Filed: 1981-08-06
Abstract: The invention relates to a process for the cleaning of squeezing rollers and to a squeezing roller and an apparatus for carrying out the process. The aim of the invention is to allow a high squeezing effect of squeezing rollers during their entire lifetime. The object of the invention is to free squeezing rollers, equipped with a capillary-active roller covering, of foreign substances deposited in the capillaries and impairing the effect of the squeezing roller. This object is achieved, according to the invention, by means of a process, in which a cleaning medium is fed to the interface between the roller core and roller covering, flows through the capillary cavities of the roller covering under the effect of pressure and/or centrifugal force and causes deposited foreign substances to be detached and transported onto the outer face of the roller covering. The invention includes, furthermore, a correspondingly designed squeezing roller and an apparatus for carrying out the process. <IMAGE>

Title: Semiconductor device
Inventor: SCHIERZ WINFRIED ING GRAD
IPC: H01L23/36
Filed: 1981-10-31
Abstract: Connection is replaceably made to a large-area semiconductor body of a semiconductor device by means of contact pieces, the semiconductor body being airtightly enclosed in an essentially disc-shaped cavity partly formed by the contact pieces. The particularly inexpensive assembly and the replaceability of all the parts is the result of the fact that a stack is formed from a semiconductor body and one contact piece on each of its contact areas, that the stack is situated between large-area metal parts which, together with an insulator body situated inbetween, form the cavity, which is airtightly sealed by sealing means, and that oppositely situated surfaces of the components forming the cavity are optionally suitably shaped to provide mutual location. As a concentric guide for the stack, these components may be provided with suitable projections in the cavity. The insulator body may be of annular or plate-type construction, with a suitable opening. The metal parts may have projections which also serve as contact pieces.

Title: Process for treating soils with a cysticide
Inventor: SCHWARTZ ROBERT D DR MED
IPC: C05G3/60
Filed: 1981-12-11
Abstract: A chemical which has cysticidal properties is selected and diluted forming a cysticidal agent, and the latter is mixed with a medium employed for soil treatment, for example a fertiliser, insecticide or herbicide. The preferred cysticidal chemical is cetylpyridinium chloride. If the medium is solid, the cysticidal chemical can be adsorbed onto a carrier and then incorporated by mixing. The process allows the infection chain caused by human amebiasis to be interrupted outside the human body.

Title: Self-limiting differential
Inventor: HEESCH DIETER
IPC: F16H48/20
Filed: 1982-04-20
Abstract: The invention relates to a differential with automatic differential-speed limitation, in particular for motor vehicles. In this construction, independent rotation of both driving wheels is guaranteed up to a predetermined tolerance limit (cornering). If this limit is exceeded, the differential-speed limitation automatically comes into operation, both in forward travel and in reverse. This is achieved by virtue of the fact that the differential is connected to the limiting unit via its output shafts by unequal gear wheels, the mode of operation of the said limiting unit being based essentially on the operation of self-reversing freewheels. <IMAGE>
