Patent DE-3728822-A1 (DE)
Inventor: VACHONIN MICHAIL EVGENEVIC
IPC: G01P3/36
Filed: 1987-08-28
Abstract: In a method of calibration of the velocity scale of a Mössbauer spectrometer, the motion of the vibrator rod (1) of a Mössbauer spectrometer is converted (3, 8, 9) into interference video pulses which are recorded by a memory device (10). Simultaneously with this recording, the time intervals between the instants of recording the interference video pulses are also recorded by the memory device (10), said intervals being used by a computer (13) for evaluation of the calibration characteristic of the velocity scale of the Mössbauer spectrometer. The interference system comprises laser 5, fixed mirror 6, movable mirror 7 attached to the vibrator rod and beam splitter 4. The output of detector 8 is converted to zero crossing pulses at 9 which pulses are supplied to counter 11 fed from clock 12, and to memory 10. Computer 13 calculates the velocity for each increment of motion and also controls, via 14, the vibrator 2 driving vibrator rod 1 which carries the gamma source 15. <IMAGE>

Title: Apparatus for stretching a moving web of material
Inventor: STEFFL MANFRED DIPL ING
IPC: D06C3/02
Filed: 1987-12-08
Abstract: Apparatuses for the biaxial simultaneous stretching of a moving film web are generally restricted to a stretch ratio of at most 4 : 1. The reason for this lies in the kinematics of the scissor chain links used. The object is to further develop such an apparatus in such a way that a stretch ratio of more than 4 : 1 can be achieved unproblematically even when using scissor chain links. Higher stretch ratios are achieved in the case of such an apparatus with carriages (15), which can move along a first guide means (13), and scissor chain links (9), acting at the said carriages, by there being provided in the opening region of the chain scissor links (9), and consequently for enlarging the distance between two neighbouring gripping devices seated on the carriages (15), an adjustable auxiliary or spreading mechanism or such an adjustable arrangement (27). The apparatus is suitable in particular for the stretching of plastics film webs. <IMAGE>

Title: Method for pneumatically conveying bulk materials with metering possibility
Inventor: PRITSCHOW GERD DIPL ING
IPC: B65G53/66
Filed: 1988-01-28
Abstract: In this method, at the end of a conveying line, a suction is produced in the line by means of a unit, while, at the beginning of the conveying line, another unit provides for the metered addition of a sufficient quantity of fluidising and conveying gas in order to ensure the blockage-free transport of the bulk material, which likewise is subjected to a defined feeding, through the conveying line. Accurately functioning, continuous or discontinuous metering is achieved by means of various possibilities, for example varying the efficiency of the units, addition of conveying gas into the conveying line, valve control by means of a valve integrated in the feed unit. In the further development, the use of flexible hoses as conveying lines is provided, which conveying lines, having a small diameter, reliably transport the material over distances greater than 100 m. Furthermore, the control of the exit speed of the bulk material is ensured in a simple manner without the conveying line itself being affected by this. The method is outstandingly suitable for conveying and metering bulk materials directly from a container, by means of many thin lines, to a receiver situated a relatively long distance away.

Patent DE-3829007-A1 (DE)
Inventor: MATENTZOGLU NIKOLAUS
IPC: C23C14/02
Filed: 1988-08-26
Abstract: A titanium nitride (hardmetal) coating applied in particular on a tool (base material) for the purpose of reducing wear should not be thicker than 5  mu m if it is to exhibit a quasi-plastic behaviour appropriate to the properties of the base material when mechanically stressed. However, this low coating thickness does not afford sufficient protection against corrosion to the base material because of the porosity of titanium nitride coating. To remedy this, the invention proposes that a nickel coating approximately 20  mu m thick be first applied on the object to be coated with the hardmetal. The nickel coating ensures adequate protection against corrosion and is protected from mechanical damage by the hardmetal coating. The nickel coating is preferably annealed at approximately 400 DEG C after application, in order to attain a hardness intermediate between that of the base material (approximately that of tool steel) and that of the titanium nitride coating.
Patent DE-3830401-A1 (DE)
Title: Ejector of imperfect objects
Inventor: KIEFER ERNST DIPL ING
IPC: B65G47/84
Filed: 1988-09-07
Abstract: The invention relates to an ejector of imperfect objects. The objects are continuously transported in a row on a conveyor belt and the object which is recognised as one which is to be removed is ejected from the row. In the known ejectors, either the position of the ejector axis or its pushing-function curve is combined in a disadvantageous manner, that is to say ejectors having a vertical axis engage well with the object but have an unfavourable pushing curve, and ejectors having a good pushing curve engage poorly with the object since they engage at only one point. The invention has the object of eliminating the said deficiencies on the basis of its design. The object is achieved in that a two-winged cam rotates 180@ per object ejection, about a vertical axis. <IMAGE>

Filed: 1989-02-02
Abstract: In a method for measuring the inside diameter and the form errors of small bores by emitting light waves and evaluating their reflection, it is provided that the light of a fibre optic light transmitting device is fed into the entrance end of a special fibre optic device, guided in the fibre and led out at the exit end and reflected by a bore inner wall in such a way that it is coupled in again at the exit end of the fibre optic device, guided to a fibre optic receiving device and converted by the latter into voltage values which are proportional to distance. In a device which comprises a measuring device having an optical transmitting device and an evaluating device, the optical transmitting device consists of a fibre optic optical device (30) whose light is received by the entrance end of a fibre optic device (S), and it is provided that the fibre guides the light in the fibre optic device (S) and leads it out at the exit end, and that the light reflected from the bore inner wall is guided, coupled in again at the exit end of the fibre optic device, to an optical receiving device which transforms the light into voltage values proportional to distance. <IMAGE>
Patent DE-3910315-A1 (DE)
Title: Multiplication circuit
Inventor: MERKLE PAUL
IPC: G06F7/52
Filed: 1989-03-30
Abstract: The position multiplication circuit according to the subject of the invention differs from the position multiplication circuit according to P 3910324.2 mainly in that it does not process the decimal digits in 5211 code and supply the result number in this 5211 code, but processes decimal digits in 54321 code and supplies the result number in this 54321 code as well. The adder circuit 5 thus processes decimal digits in 54321 code, and also supplies the result number in 1-out-of-10 code. The remaining fixed-value (constant) circuit 2 can be triggered directly, since it can only be triggered in 54321 code. The times 5 circuit 1 supplies its intermediate result number in 54321 code, like circuit 3. <IMAGE>
