Abstract: ABSTRACT OF THE DISCLOSURE           In the method of flash butt welding, wherein the workpieces to be welded are continuously moved to-wards each other in the course of fusion, the improvement consists in that the workpieces are at first continously moved towards each other with monitoring their thermal state in terms of current, or power, or fusion time, or length of the fused portion, and after any of said vari-ables has reached a preselected value which corresponds to the predetermined heating of the contact region, oscillatory movements are superimposed on the movement of one of the workpieces towards the other and the fusion process is carried out till upsetting.  The method is useful in welding large-section workpieces.

Abstract: ABSTRACT OF THE DISCLOSURE An adjustable dosage syringe is provided wherein the syringe plunger has sets of multiple closely spaced in-dentations along the length of the plunger, and a dosage selection ring disposed around the plunger.  The inside circumference of the dosage selection ring has protube-rances which are registerable with and receivable in one of the indentations of the sets of indentations so that when one protuberance is received in an indentation of the first set of indentations, the other protuberance is also received in an indentation in the second set of indentations.  Chan-nels are disposed along the length of the plunger for simultaneously and slidably receiving the protuberances so that the ring is longitudinally slidable along the length of the plunger.  Thus, any desired dosage may be achieved by rotating the ring so that the protuberances are disposed in the channel, sliding the ring along the length of the plunger, to that point corresponding to the desired dosage, and rotating the ring so that the protuberances are received by the indentations.  The plunger is then forced into the syringe until the ring is engaged by the barrel of the syringe and stops further movement of the plunger into the syringe.

Abstract: A B S T R A C T            GAS SENSOR ELEMENTS AND METHODS OF MANUFACTURING THEM       A gas sensor element for detecting the presence of a flammable gas comprises an electrical resistance filament   surrounded by a bead which is formed by an array of alumina particles interspersed between and bound together only by particles of a catalyst for inducing catalytic oxidation of flammable gases to form an open porous gas diffusive skeletal matrix having a mean particle size of less than 20 nm.  When the bead includes such a matrix, the number of active sites at which catalytic oxidation of flammable gases can take place is greatly increased with the result that the sensor element is very resistant to poisoning by atmospheric contaminants such as traces of silicone and sulphur compounds.  The sensor thus has a very much. longer life and does not require such frequent recal-ibration.

This arrangement/configuration is realized by a specific sequential combination of steps which includes a step of upward diffusion of impurities from the highly doped regions of a substrate.          An additional minor advantage originated from this method is exclusion of a so-called non butting process.

When the free end of the drill string arrives at the outlet, one end of a casing string is attached thereto, and the casing string is pulled back through the entire borehole so that the borehole is cased from the outlet to the inlet, or vice versa.  The casing is perforated adjacent to the pay zone so that the hydrocarbons may flow from the pay zone into the interior of the casing.  Production is achieved through either of the spaced inlet or outlet; or, by using one vertical length of the borehole to force fluid to flow through the entire borehole, thereby forc-ing the production to the surface.

The plates (14, 16) are preferably mounted on a continuous conveyor (18) for automatically moving the container (12) from a loading station where the container is inserted between the plates (14, 16), to an opening area where a portion (47) of the container (12) is removed to provide access to the contents (24), and from there to a compression posi-where the plates (14, 16) are forced together to discharge the contents (24) from the container (12) through the ac-cess opening.  For frozen contents, the plates (14, 16) and container (12) may also pass through a thawing area (82) where the container (12) is heated sufficiently to free it from the frozen contents (24).
