Patent DE-2849598-A1 (DE)
IPC: B22D1/00
Filed: 1978-11-15
Abstract: To adjust or correct the composition of an iron/carbon melt, a standard test specimen is cast before the main casting; the differential calorimeter curve (D) determined with this is stored in a computer and subtracted from the likewise stored total heat line (G) of the desired melt. The curve (D') computed from the curves (D and G) shows the release in time of the heat of solidification, from which it can be judged whether the melt is or is not suitable for casting a certain workpiece. <IMAGE>

Title: Curtain rails assembled from short mouldings - positioned by dowels on supports forming tracks for sliding rings
Inventor: HEPPERLE ERWIN
IPC: A47H1/022
Filed: 1979-01-10
Abstract: A number of mouldings, e.g. made of wood, of different lengths and contours with an external lengthways extending profile and end faces which suit each other, form a rustic or period curtain rail. On their upper surface the mouldings have a longitudinal groove which lines up with those of the other mouldings when a support profile is threaded through and dowels are fitted. The support profile may be a tube or a tee section, and the groove has a "U"-section in which a rectangular strip of noise damping, low friction, synthetic material is placed on which the curtain rings roll or slide. With the invention, curtain rails which correspond to "style furnishing" can be produced in small quantities without a great outlay for materials and labour, and highly ornamented curtain rails with a massive appearance can be manufactured easily.

Title: IC engine knock detector circuit for capacitive sensor - compares filtered and unfiltered demodulator outputs and requires no tuning
Inventor: SCHRAMM HERBERT DR ING
IPC: F02P5/152
Filed: 1979-05-08
Abstract: The device for the detection of knocking in internal combustion engines contains few and economical components and requires no ref. window. If a window is reqd. only one measurement window is necessary. The exact knock frequency does not need to be known for tuning purposes. The time history of the knock signal amplitude is obtd. via a demodulator circuit whose output is filtered by a low pass filter. The outputs of the demodulator and filter are compared in a comparator whose output is tested against an adjustable measurement window. A capacitive detector is used and its impedance may form part of a high-pass or band-pass filter. The low-pass filter and demodulator circuit ref. levels are adjustable. The demodulator may be a rectifier or squarer.

Title: Incubation appts. for biological samples - has computer controlling circulation of sample containers through incubation chamber
Inventor: BAGSHAWE KENNETH DAWSON
IPC: G01N35/02
Filed: 1979-05-30
Abstract: Appts. for incubating samples in containers comprises a temp. controlled incubation chamber through which the containers are circulated along a closed path. Circulation of the containers is controlled by a computer which identifies a specified container at the end of a preselected time period and brings it into register with a sample removal mechanism which removes the sample from the chamber. Used for incubating biological samples for analysis, e.g. in radioimmunoassay or enzyme assay. Because of the continuous circulation of containers through the incubation chamber reagent can be added to a sample at an intermediate time during the incubation by suitably programming the computer.

Title: Radioactive waste storage container casting - internally plated with smooth decontamination layer
IPC: G21F5/008
Filed: 1979-08-04
Abstract: A cast iron or cast steel storage container for radioactive waste, esp. spent nuclear fuel elements, is first machined on the inside by removing at least a 1 mm thick layer electrolytically, using NaCl or NaCO3 as the electrolyte, to produce a surface with a surface roughness of 10 mu. A decontamination layer is applied to this surface by electroplating or chemically, or both in succession, followed by an electrolytic smoothing operation. This creates a safe bond between parent metal and decontamination layer which lasts for long periods without creating cracks or pores.

Title: Obtaining diesel oil esp. from coal-processing prods. - by two=stage catalytic hydrogenation
Inventor: EISENLOHR KARL-HEINZ DR ING
IPC: C10G65/08
Filed: 1979-08-31
Abstract: A process is claimed for making diesel oils from feedstock oils obtd. (a) from coal by low temp. combustion, hydrogenation, or gasification with O2 and H2O; or (b) by hydrogenation of a crude phenol fraction boiling above 200 deg. C, obtd. e.g. from coal-processing waste water. The feedstock oil is hydrogenated (i) over a catalyst contg. Co, Ni, Mo and/or W, to remove the heteroatoms; and (ii) over a catalyst of supported noble metal or Ni, to convert aromatics to naphthenes. The two catalyst beds may be in the same or different reactors. H2 is circulated counter-currently to the oil, and carries off S cpds. Process improves the ignition quality of the feedstock oil without wasteful cracking.

Title: Vulcanisable rubbers contg. natural rubber and polybutadiene blends - with increased heat resistance, used for pneumatic tyres
Inventor: WESCHE HERBERT DIPL CHEM DR
IPC: B60C1/00

Used for the mfr. of pneumatic tyres, esp. rolling strips, and for rubberising the solid supports in pneumatic tyres. The addn. of the synthetic polybutadiene rubber increases the heat stability of the vulcanisate without adversely affecting the spontaneous heating of the vulcanisate under dynamic stress.

Title: Plasma prodn. process without electrodes - pulse modulating EM HF or VHF field so that gaps are longer than pulse lengths
Inventor: BEERWALD HANS DR RER NAT
IPC: H05H1/46
Filed: 1979-10-13
Abstract: This plasma prodn. method limits thermic loading and heat loss without reducing the plasma thickness. An e.m. high or very high frequency field is employed obviating electrodes. The field is pulse modulated. The pulse strength is greater than that of a continuous wave signal necessary for a stationary discharge in a similar average plasma thickness. The pulse gaps are at least greater than the pulse lengths by an amount ensuring that the mean power provided is less than that necessary for a continuous wave signal for a stationary discharge in a similar average plasma thickness. A pulse generator can be assigned to the current supply unit.

Title: Vehicle speed and spacing measuring device - uses spaced mechanical pulse generators coupled to evaluation circuits which are linked to automatic camera
Inventor: BIERBERG GUENTHER
IPC: G01P3/66
Filed: 1979-11-09

Title: Laser beam mining tunnel direction indicator - has compact beam reversal unit for greater distances while maintaining accuracy
Inventor: SCHMIDT GUENTER
IPC: G01C15/00
Filed: 1980-06-26
Abstract: A laser beam device (1) for determining the tunnelling direction in mining applications overcomes the distance limitations usually encountered with such devices.
