Abstract: A process for the recovery of the uranium present in phosphoric acid produced by a wet process in (A) by means of a suitable solvent (L.sub.9), which is carried out after separation of the gypsum in (B) formed in the attack operation, and elimination of the solid materials which are still in suspension, characterized in that, in order to avoid the formation of dross in the course of the operation of extracting the uranium which is previously reduced in (D), the step of eliminating the solid materials which are still in suspension is effected by a final solid-liquid separation operation in (C) and/or in (E), prior to extraction of the uranium in (F), in the presence of an added fraction of gypsum (S.sub.22) and/or (S.sub.23) resulting from the production of H.sub.3 PO.sub.4.

Abstract: A method for cold rolling a tubular blank using a Pilger rolling mill, the tubular blank being rolled between a mandrel, lodged inside it, and the grooves of a pair of rolls, mounted within a stand which performs a back and forth motion along the axis of the tubular blank, the rolls being driven in rotation alternatively in one direction and in the other, in synchronism with the movements of the stand, a forward motion of the blank being done at least at proximity of the downstream neutral point. During at least a part of the return run of the stand, a holding back device, placed on the downstream side relative to the stand, prevents the displacement of the already rolled tubular blank along the rolling axis in the upstream direction during the return rolling run.

Abstract: The invention is an ink drop catcher for use in a drop marking device such as an ink jet printer. The catcher receives drops which are not to be deposited on the recording medium. The catcher includes a convoluted passage through which the drops pass to return to the ink supply. An electrode disposed along the convoluted passage senses the current flow created by the accumulation of the charges from a series of test drops. This current flow is used by phasing circuitry to insure that the drops are correctly charged at the time they are formed.

Primary and secondary curved and tapered cantilever arms extend inwardly from the top wall. The cantilever arms are provided with contoured tips to facilitate sliding movement of arms during latching engagement of the flat wire bundles.

Abstract: A process for the removal of cadmium contained in wet-process phosphoric acid by flotation by means of a cadmium-collector anionic surface active agent and an injected gas in the presence of other impurities including iron and possibly uranium which is characterized in that, in order to improve the removal of cadmium, the iron contained in the phosphoric acid in the trivalent state is reduced to the divalent state before the cadmium collector is introduced into the medium to be purified by flotation.The collector agent is selected from the group of dithiophosphoric acid esters and the alkali metal salts thereof.

Abstract: A ratchet wrench for adjustment of scaffolding screw jacks. The wrench includes a head member having an asymmetrical passage of fixed dimension adapted to receive the scaffolding leg. Dog members or flippers are positioned adjacent the passage in the head and are retained for perpendicular pivotal rotation with respect to the head. Each flipper includes an engaging surface and a sloped relief surface. Gravity induces the downward rotation of the flippers permitting the driving engagement of the jack in a first direction while contact between the screw jack and sloped flipper relief surface urges the flipper upwardly facilitating the non-driving wrench return stroke. The flippers are symmetrically designed thereby facilitating the selective raising or lowering of the screw jack simply by positioning the wrench with the appropriate head surface facing upwardly.

Abstract: Fuel is held under high pressure by an accumulator which is connected with injecting nozzles by respective fuel pipes. The fuel pipes are each provided with a timing control valve and a quantity control valve, and these valves are controlled by an electric control apparatus. The control apparatus controls the timing valve in response to the angular position of the engine and controls the quantity control valve in response to the engine load, whereby the injecting nozzle injects the proper quantity of fuel at the proper moment.

Abstract: The process and the device according to the invention relate to the continuous casting of hollow bodies made of metals such as aluminum, copper, steels of all types or other metals or alloys. The process involves introducing the liquid metal into an annular space between an external mold and an internal mandrel, the liquid metal being subjected in the vicinity of the mandrel to the action of a moving magnetic field which drives it upward. This field is created by a magnetic rotor housed in the mandrel comprising a rotating part around which is arranged at least one spiral made of magnetized magnetic material made integral with the rotor by at least one collar. The process is applied, in particular, to the production of blanks intended for the manufacture of seamless tubes.

Abstract: A method and ceramic mold structure for use in producing articles having a predetermined crystalline orientation such as single crystals. The technique involves the use of a ceramic mold mounted on a chill plate with the mold defining a cavity tilted at an angle between about 5.degree. and 75.degree. relative to the vertical. One or more seed crystals are supported adjacent the chill plate and the orientation of the crystal is selected to provide a desired orientation in the resulting casting. The method results in improved solidification control, particularly with reference to avoiding defects caused by shrinkage.

Abstract: The invention employs an execution control unit consisting of a look up memory, three instruction registers and logic gates to control pipe line processing by an ALU. During such processing the sequential steps required to execute a program instruction are overlapped so that the ALU and its associated memory are always busy. The three instruction registers are provided to receive and retain up to three instructions which may be in process at a given time. The memory is preferably divided into a plurality of banks to improve the performance of the system by reducing the occurrence of a memory busy condition. To facilitate pipe lining an instruction format is employed having a fixed location for the data field which specifies the register to be used for address preparation.
