IPC: C22B3/16
Filed: 1985-09-18
Abstract: Process for extracting zinc from silicate zinc ores, in which the comminuted ore is put in suspension in water, the aqueous or suspension is extracted with an alkyl phosphoric acid ester at a pH value of 1.4 to 3.5 and at a temperature of 20-90<o>C for a period of 30-300 minutes, the organic zinc-containing phase is separated from the aqueous solid-containing phase, the organic zinc-containing phase is treated with diluted sulphuric acid and the aqueous zinc sulphate solution is subjected to electrolysis to precipitate the zinc. According to this process, in the aqueous phase of the suspension during treatment of the suspension with an alkyl phosphoric acid ester, a dissolved silicic acid content of between 20 and 60 g SiO2/l is achieved by the addition of water or ores.

Patent DE-3538412-A1 (DE)
Title: Urea ointment
Inventor: KRAINBRING VOLKER DR
IPC: A61K47/00
Filed: 1985-10-29
Abstract: A urea ointment based on an O/W emulsion is described, which is suitable for the treatment of skin which is particularly highly affected by drying out. The ointment has a very good refatting system, is absorbed rapidly, keeps the skin supple and has a very good granulation-promoting action. On very highly dried-out skin, the ointment surprisingly has the action of a W/O emulsion, but after application exhibits no fat residues on the skin, which in the case of W/O emulsions is sensed as unpleasant and disadvantageous. In addition to urea, the ointment essentially contains sorbimacrogol fatty acid esters, cetyl alcohol and/or cetyl stearyl alcohol, anhydrous eucerine, lactic acid, preservative and distilled water in amounts which are specified in each case.

Title: Automatic payment-collection and monitoring system
Inventor: BALLMOOS FRITZ VON DR
IPC: G07B15/02
Filed: 1986-03-12
Abstract: The system contains in the entry checking device (10 and Figure 2) a magazine (36) with a store (37) of parking tickets which were individually marked before being inserted into the magazine. The entry checking device also contains a reader (39) which interacts with an electrical central unit (13) in order to store the marking of each parking ticket issued and its time of issue. The cash register (12) of the system contains a reader which, when a parking ticket is inserted, calls up the associated time of issue and calculates the parking fee from the time difference. After the fee has been paid, the time of issue is erased in the memory and the time of payment is stored. The exit checking device (11) contains another reader which calls up the time of payment when the parking ticket is inserted and opens the exit barrier (16) when the time interval between the time of insertion and the time of payment is with a predetermined tolerance time. The system does not contain any mechanical punching mechanisms which considerably reduces its production costs, simplifies maintenance and increases operational reliability. <IMAGE>

Abstract: Process for producing sintered nuclear fuel elements from powder of uranium dioxide which contains from 3 to 12 per cent by weight of Gd2O3 and possibly up to 20 per cent by weight of U3O8. According to the invention, bodies pressed from the specified powder are sintered at a temperature of at least 800 DEG C in an atmosphere which at 1700 DEG C has an oxygen partial pressure between 0.15 . 10<-11> and 1.25 . 10<-11> atm. As a result of the low oxygen partial pressure during sintering, oxygen-ion vacancies are formed in the lattice of UO2 . Gd2O3 in the sintered bodies, which results in reduced diffusion of fission gases from the nuclear fuel elements.

Title: Isolating plug distributor for power supply networks in the medium-voltage range
Inventor: JASCHKE GEORG
IPC: H02B13/02
Filed: 1986-04-19
Abstract: Distribution devices play a major role in power supply networks. In this case, the trend is clearly towards plug-in devices. Plug-in devices have the advantage that they can be disconnected and connected again relatively easily. The problem exists in this case of strengthening an isolating plug distributor to such an extent that it can be used in a cable distribution cabinet. In this case, the cable ends 5 of a three-phase network coming out of the ground are inserted, combined into groups of three phases, into the housing 11 of a cable distribution cabinet and are terminated by straight cable plugs 51. The cable plugs 51 are in this case attached to a mounting 27 at the same height, which are connected to a supporting framework 2 of the cable distribution cabinet 1. A horizontally arranged distribution plate 4 which (in the switching state) is detachably connected to the mounting 27 is now used for each phase. Each distribution plate 4 can be disconnected from the cable plugs 51 by means of a lifting device 6 when the housing 11 of the cable distribution cabinet 1 is raised, can then be rotated and can be connected again with a new switching function. <IMAGE>

Title: Non-contacting conveying device
Inventor: AKASHI HIROSHI
IPC: H01L21/683

Abstract: The invention relates to a non-contacting conveying device for conveying high-precision workpieces. The conveying device has a housing which is closed at the top and open at the bottom, which is provided in its upper region with an air feed nozzle and whose lower clear end region is rounded off and continuously curved. By means of a feed of air into the housing, a partial vacuum is formed in the latter if the distance from a workpiece is relatively large, as a result of which the workpiece can be lifted. If the distance from the workpiece becomes smaller, a positive pressure is formed which presses the workpiece away from the housing. <IMAGE>

Title: Method and machine for cutting helical bevel gears
Inventor: ARITA KOICHI
IPC: B23F9/10
Filed: 1986-12-22
Abstract: A method for cutting helical bevel gears comprises the steps of controlling a cutter in two mutually perpendicular directions, in order to cause a circular movement of the cutter and a rotation of a blank at a rotational speed in relation to the circumferential speed of the cutter, in order thus to produce the teeth of a helical bevel gear. A machine for cutting helical bevel gears, including hypoid gears, comprises a working-head saddle (32) and a column (24) which are each displaceably driven in mutually perpendicular directions on a bed (21) of the machine. A working head (35) with a working-spindle shank (37) rotates on a blank (39) mounted thereon. The working head is displaceable on the working-head saddle angularly relative to the sliding directions of the working-head saddle. The machine furthermore comprises a cutting head (27) for attachment of a cutter (30). The cutting head is attached to the column and is displaceable in directions perpendicular to the sliding directions of the working-head saddle and the column. Control means comprise a numerical control for controlling the sliding movements of the working-head saddle and the column on the bed and the rotations of the working-spindle shank on the working head. The gear-cutting machine does not use any slide (carriage) and is therefore constructionally simple and permits automation of all operations, ...   Original abstract incomplete. <IMAGE>

IPC: G01N21/33
Filed: 1987-04-29
Abstract: Ultraviolet radiation generated by a light source is applied to a light-absorbing cell in which a gas which is to be investigated is kept at high temperature. A wavelength modulation spectroscope in a housing which is thermally insulated with respect to the cell and has a controlled internal temperature is applied to the cell and the light passing through gas contained therein. The light modulated by the wavelength modulation spectroscope in the region of the wavelength from 207 to 211 nm in accordance with the absorption spectrum of ammonia gas is converted into an electric signal by a photoelectric transducer. The signal is sampled at a frequency which is twice the modulation frequency of the spectroscope, and is conditioned to form a d.c. voltage signal corresponding to the absorption spectrum in the wavelength region from 207 to 211 nm. The absorption spectrum in the wavelength region from 207 to 211 nm corresponds to the concentration of ammonia gas in the gas to be investigated.
