Title: Steel refining by oxygen lancing and bottom blowing - for improved quality steel of various grades
Inventor: BERTHET ARISTIDE
IPC: C21C5/35
Filed: 1975-08-29
Abstract: A process for mfg. steel by refining pig iron with industrially pure O2 is described. The O2 is introduced via a lance and at the same time the metl is stirred by bottom blowing with an inert gas opt. mixed with O2. The process combines the advantages of both bottom blowing and O2 lancing. Various grades of steel can be obtd. The quality is improved due to a low rate of decarburisation, significant rates of desulphurisation and dephosphorisation and a lowering of the amt. of O2 dissolved in the metal. Less basic slags which contain smaller amts. of Fe oxide can be worked. This leads to reduced consumption of lime, O2 and oxidised Fe. The O2 blowing time is also slightly improved. Desulphurising or dephosphorising agents may be added with the bottom blown gas. Measurements necessary in automated process, e.g. analysis and temp., are more exact and the results are better.

Title: Automatic connection of winding ends into commutator slots - involves using toothed wheels for wire location and insertion into bar
IPC: H02K15/06
Filed: 1975-09-02
Abstract: The application is to the automatic winding of small d.c. machines and is concerned with mounting the commutator on the armature shaft and with making off the winding ends into the commutator bar slots. The armature (5) is set up on a base together with the commutator (6) whose bar slots are aligned with reference slots (12) in the base (4). The shaft is pressed home by a hydraulic ram. A sprocket mechanism, mechanically interconnected with the base has two toothed wheels (14, 15). The first locates the end winding leads in the correct position (13) in relation to the slot, whilst the second (15), half a tooth pitch away, then presses the wire into the commutator slot. The combined mechanism then moves round one pitch to repeat the process until all the ends are made off. The connections can then be soldered.

Title: Perforating endless lengths of material by electrical discharges - fibrous webs, expanded films etc, pass between rotary electrodes
IPC: B26F1/28
Filed: 1975-11-26
Abstract: Continuous lengths of matl. ranging from fibrous webs and paper to polymer films or sheets, ready formed, possibly expanded into a cellular structure or extruded and stretched from a mixt. of a linear polymer with an expanding agent, fed directly from the extruder, are perforated by electrical discharges. The run is passed through an electrode system consisting of a first and second electrode between which there is a high frequency potential difference. Electrical discharges take place between the points of the first and second electrode which are in the closest proximations. At least one electrode is rotated and is formed so that a zone on its surface which at any monent is closest to the surface of the other electrode, approaches in a direction having a component parallel to the axis of rotation. Severe corrosion of the electrodes causing irregularities of the pattern, are avoided. The gap between the electrodes does not allow energy to be absorbed but is adequate for the passage of the goods without possibility of damage.

Title: Antibiotic susceptibility testing of clinical specimen - transferred to test wells in cartridge holding culture medium and antibiotic
Inventor: GIBSON SANDRA F
IPC: C12M1/20
Filed: 1976-03-15
Abstract: A cartridge contains a number of individual wells linked by passages to a filling port. A clinical specimen is introduced into the filler port and fills the wells which are each provided with an overflow cavity to collect air bubbles during the filling operation. The cartridge is transparent and prior to use a pref. freez-dried culture medium is placed in each well so that microorganism growth within a well can be detected optically. Known quantities of antibiotics are introduced into some of the wells while one well contains no antibiotic. After filling the cartridge with the specimen it is incubated and the wells are examined for growth. The apparatus determines the susceptibility of microorganism to an antibiotic without isolating the microorganism. The culture medium will only support the required microorganism and the effectiveness of the antibiotics is detected by comparing the growths in the antibiotic-free well with the remainder. Determination of the effective antibiotic concentration is faster than previously.
