Patent DE-2040117-A1 (DE)
Title: Stereospecific determn of l-thyronine - applicable in presence of large excess of d-thyronine
Inventor: NEUDECKET HORST DIPL-ING
IPC: C12Q1/28
Filed: 1970-08-12
Abstract: L-Thyronine is determined quantitatively by treating the aqs. soln. to be analysed with L-amino acid oxides, reacting the hydrogen peroxide thus liberated with peroxidase and a dyestuff precursor selected from o-dianisidine, o-toluidine, benzidine and other hydroxy- or amino-substd. o- or p-diphenyls, and colorimetrically determining the dye thereby formed. The procedure can also be used for determining L-diiodothyronine, L-triiodothyronine or L-thyroxine when these substances are deiodinated to L-thyronine before the analysis. The analysis is stereospecific and is capable of determining very small amounts of L-thyronine in the presence of a large excess of the D-isomer. This is of particular importance in ensuring that therapeutically important D-thyroxine and D-triiodothyronine do not contain dangerous amounts of the L-isomers.

Title: Fluidised bed assembly - for treatment of particles eg drying
Inventor: RENSSEN HENDRIK VAN
IPC: B01J8/36
Filed: 1971-08-06
Abstract: Appts. has at least two chambers, the particles to be treated being fed to the first chamber and subsequently being transported through one or more succeeding chambers to a discharge, and each chamber having a bottom plate with openings through which a stream of gas is blown to maintain the particle bed in that chamber in a fluidised state and to subject it to a required treatment, and also having a gas outlet at the top. Additionally the appts. has (a) a connecting passage at the discharge side of one chamber which can be closed by a valve connects more or less smoothly to the bottom of the chamber so that particles discharge takes place exclusively as a result of the difference in level between adjacent chambers, (b) the stop valves in these passages are connected to operating devices so that at any given instant at least one valve is closed, in order to prevent the continuous discharge of particles while the particles are retained in the chamber or chambers succeeding the first chamber for a predetermined residence time since the inlet and outlet valves of the (these) chamber(s) is kept completely closed during this time.

Patent DE-2224049-A1 (DE)
Title: Rotary inclined cement kiln - automated control of fuel supply and speed
Inventor: HERZ JOSEPH HERMAN
IPC: F27B7/38
Filed: 1972-05-15
Abstract: In a method of controlling the operation of an inclined rotary cement kiln, as the sensed maximum temp. in the burning zone decreases within a first range, the control mode is such that the kiln speed is kept constant whilst the fuel supply to the main burner is progressively increased. When the sensed maximum temp. decreases within a second range, the control mode is such that fuel supply is kept constant whilst the speed is progressively reduced. As the temp. increases within a third, overlapping range, after reduction of the speed to a certain minimum, the speed can be increased relatively rapidly.

Title: Flat roof safety railing - has continuous wire mesh to prevent accidentally falling over roof edge
Inventor: ZAPPE BERND
IPC: E04F11/18
Filed: 1973-06-19
Abstract: The whole extent of the flat roof is encompassed by the railing arrangement. On the edge of the roof are fitted sleeves for insertion of the railing posts. A sleeve has a flange which rests on the concrete surface of the roof. This sleeve passes through the insulating layer and through the layer of gravel on the roof top. A tubular railing support post is inserted into this sleeve from the top. The tubular support has also a flange, which comes to rest against the top of the sleeve. This flange regulates the insertion depth of the support post. A transverse locking hole is drilled through the sleeve and the tube and a locking pin is pushed through it. The railing arrangement can be dismantled. The tops of the uncovered support sleeves are protected by means of covering end caps against entry of rain.

Title: Rail system for controlled tracks - guide rail is divided into main and branch sections, with bridging rails
Inventor: BIRMANN FRITZ PROF DR ING
IPC: B62D1/26
Filed: 1973-11-10
Abstract: The rail system is for passenger- and/or goods vehicles, with pneumatic tyres, moving on tracks, and which have a steering axle with running wheels. The axle is controlled via a pair of guide rollers, by a guide rail, with prism-shaped heads. The guide rail maintains permanent guidance in any direction, at track branches. At these points, the guide rail is divided into one stationary main rail, and several stationary guide rails ending at a distance from the track. Each of these rails has a decreasing acute angled cross-section. Bridging rails with corresponding cross-sections form complementary members between the main- and guide rails. The pointed ends of the bridging rails are alternately swivelled, from outside, into support contact with the similar sections on the main- and guide rails.

Title: Drill with logging facility - cable led down inside drill string has non-rotating bottom probe
Inventor: JOHNSON MCCULLOUGH IRA
IPC: E21B47/12
Filed: 1973-11-23
Abstract: Drill combined with logging facility consists of a power rotated bit at the bottom of a forcibly located and fed drill rod string and an electric cable which is so coupled to the locator system that it does not rotate during the drilling and logging action. The cable runs down inside the rods close to the bit and is anchored so that it can be introduced together with the rod string. A probe at the bottom end of the cable connects directly to the bit and thus receives signals transmitted by this. The signals are led to the surface recording and display facility. The probe should be so anchored as not rotate during drilling.

Title: Two shift registers with feed-back in sender and receiver - has method for discrimination between bunch errors and synchronisation failure
Inventor: GELBRICH HANS-JOACHIM DIPL ING
IPC: H04L7/04
Filed: 1973-11-30
Abstract: Both registers generate the same pseudo-random signal trains, and are parts of a bit error measuring device which compares the received signals with the locally generated pseudo-random signal train. Error signal train generated by the bit-by-bit comparison is examined in a special circuit for whether it itself corresponds to the pseudo-Random signal train on which the comparison is based. If it does, the synchronisation failure is confirmed when bit errors are at the same time delivered at the bit error measuring device output.

Title: Well filter tube - is designed for greater strength enabling thinner walls for tube to be used
Inventor: GRAULICH HEINRICH DIPL ING
IPC: E03B3/20
Filed: 1974-06-15
Abstract: Filter tube for wells where a pipe (10) has in the direction of its length circular sections (12), with slots pushed out which have material in shape of a bridge (14) left over them. Between these circular slotted section (12) are plan circular sections (16). The width should be between 9.8 to 1.5 of the length of the slotted sections.
