Patent DE-1805241-A1 (DE)
Title: Chocolate substance mixer
Inventor: CAVALIERI EMILIO
IPC: B01F13/10
Filed: 1968-10-25
Abstract: A number of peripherally arranged, interconnected troughs are coupled up for the dry stirring stage, and a central trough or bowl can be connected with any of the peripheral troughs, all carried together in a frame. A link between the worm conveyor connecting the peripheral to the centre troughs has a hole in the bottom of the tube housing the worm so that chocolate outflow through the hole can be controlled, by opening or closing the window hole. With the hole closed during dry stirring, the chocolate cannot reach the centre trough. During emulsifying, the worm starts up and feeds to the centre. The vertical shafted motor drives the worm and pinions on the ends of the central trough rollers can be turned by gears mounted on the housing.

Title: Electronic borehole inclinometer with signal - conversion system
Inventor: G SMETANIN ALEKSANDR
IPC: E21B47/022
Filed: 1969-01-29
Abstract: Electronic borehole inclinometer provides continuous signal for easy conversion and enables nonmagnetic transducers to be used in the hole. The inserted part has phase transducers to indicate electric drill position and angle and has in circuit with these a phase splitter, connected to the drill power mains. The splitter controls a stepping switch which selects transducer output signals on a time basis and feeds these to a surface decoder via a converter which forms coded HF signals from the low frequency switch output. The HF carrier generator is connected to two modulators between the splitter and the transducers and circuited with these, the generator also switched to de-modulators which lie partly between the output of each transducer and the input of the stepping switch so that the demodulators can be used to demodulate the transducer signals in synchronism.
Patent DE-1926179-A1 (DE)
Title: Particle size determination by x-ray absorption analy - sis
Inventor: PETER OLIVIER JAMES
IPC: G01N15/06
Filed: 1969-05-22
Abstract: Employs X-rays, a converter for producing electrical signals relating to the transmission of the X-rays through a cell containing a suspension of the particles in a liquid, and a signal processing and recording system. The particles may be e.g. of kaolin clay in an aqueous suspension, with the cell containing the suspension disposed between a source of X-rays and an X-ray detector all disposed along a horizontal axis with the X-ray radiation passing through the cell being continuously measured as the vertical position of the cell is varied relative to the beam of X-rays. The operation of the apparatus is based on Stoke's law of sedimentation, and from the measurements of the transmission of the X-rays at different levels both the size of the particles and their distribution in the suspension may be determined.
Patent DE-1933043-A1 (DE)
Title: Application of thick-walled polythene - insulation to high voltage cables
Inventor: ULRICH OESTREICH DIPL-ING
IPC: B29C48/355
Filed: 1969-06-24
Abstract: The base wire is drawn from a storage drum through a worm extruder, and after the extrusion of the thick polythene layer passes through a virtually horizontal cooling section, being finally led to a reeling up drum past one or more tensioning rollers. After leaving the extruder nozzle, at least in the cooling zone, the conductor is rotated continuously and uniformly in the same direction at between 3 and 60 rph. This rotary motion may be imparted by mounting the storage drum and the wind up reel, perhaps with tension rollers, on rotating frames. This equalises the torsional stresses inherent in the use of a worm extruder.

Title: Production of crystalline zeolites of x and - y types
Inventor: FRIEDRICH WOLF DIPL-CHEM DR DR
IPC: C01B39/20
Filed: 1969-11-03
Abstract: This hydrothermal synthesis process comprises adding triethanolamine to the reaction gel formed from silicate and alumina components, and effecting crystallisation at an elevated temp. To produce an X-type zeolite, the molar ratio SiO2: Al2O3 should be about 1.7, and the amount of triethanolamine 80-120% with respect to the weight of solids components of the gel; the crystallisation is carried out at about 80 degrees C. for 7-8 hrs. for Y-type zeolite, the ratio SiO2: Al2O3 should be about 3; the triethanolamine amount 25-50%; the crystallisation temp. about 95 degrees C. and time about 10 hrs. By this method, high quality products are obtained in a short time.
