Abstract: Multipassages rotating collector intended to operate according about a substantially vertical axis. The electric paths are established by means of multiple contacts as shown (11) (in figure 11), these contacts being located on insulating supports (12) integral with a tubular skirt (13) rotatingly movable with respect to an assembly (14) forming the cover of a shell (15) which is supposed to be fixed, said cover being rotatingly movable with respect to said shell. The contacts (11) provide the electric connection with vertical conducting strips (16) carried by insulating platens (17) and arranged under said platens. Between the various stages of the collector there are arranged deflectors (18). The skirt (13) carrying the contact supports is made integral with the shell (15) by a removable finger (19). The electrical parts may be easily assembled or disassembled when the assembly fixed on the cover (14) is lifted above the shell (15).

Abstract: This anti-fraud system includes a process and devices for avoiding fraud on the price indicated by an electronic taximeter. The taximeter apparatus, which includes a luminous display unit and a computing unit, is supplied with d.c. voltage V by the vehicle battery. One particular fraud, made more difficult by this system, involves voluntary cut-off of the voltage supply to the meter. To execute this fraudulent maneuver the cabdriver firstly starts the meter, and records a price on the fare meter, with no passenger in the taxi. Secondly, before a customer is picked up, the operator cuts off the current supply to the meter, which extinguishes the fare display. Thus, as the customer enters the cab, it is not apparent that the meter has already been run-up to a non-zero value. To preclude this maneuver, the anti-fraud system has a first comparator which compares the voltage V with a reference voltage Vr and emits a constant voltage Vc if V<Vr and a zero voltage if V>Vr. Another comparison device compares the duration during which V remains lower than Vr with a reference time period duration. The computing unit and the display unit are returned to zero each time the reference time period duration is exceeded.

Abstract: En appliquant des couches tres fines de materiaux resistant a l'usure sur la surface d'un corps metallique dur, on peut prolonger sensiblement sa duree de vie en tant qu'outil de coupe de metaux. Afin d'ameliorer les caracteristiques du materiau au moyen de ces couches il est necessaire d'assurer l'adhesion entre la couche et le substrat. Sur un tel corps metallique dur on ajoute un ou plusieurs metaux, qui peuvent etre selectivement oxydes et peuvent ainsi former une couche resistante a l'usure presentant des proprietes ameliorees d'adherence et de ductilite.

Abstract: A modified Phillips-type cruciform recess in a screw or the like, which provides a cling-fit with a driver by causing deflection of the flutes of the driver against the walls of the slot in the recess, comprises a central socket portion (14) and radially extending slots (16) adapted to receive the flutes of a suitable driving tool. Each slot is defined in part by a bottom surface of substantially uniform width which slopes radially inwardly and downwardly along the axis of the screw (10). The bottom surface joins two opposing surfaces which form the walls of the slot (16). The pairs of opposite slots (16a, 16b) in the cruciform pattern are not symmetrically located relative to a plane including the longitudinal axis of the screw, but are offset laterally in opposite directions with respect to such a plane. On insertion of a standard driver into the recess, the flutes of the driver are caused to flex into frictional engagement with the walls of the slots, thereby achieving the desired cling-fit.

Abstract: Sour industrial gases containing carbon dioxide and hydrogen sulfide are treated with aqueous amine absorbents to remove the CO 2  and H 2 S. The absorbent (12) containing or loaded with H 2 S and CO 2  is regenerated (24) and the off gas containing concentrated amounts of H 2 S and CO 2  is treated in a second amine absorber (34) to produce an absorbent loaded with H 2 S. This amine is then regenerated (54) to provide an off gas containing a high ratio of H 2 S to CO 2  which can be used as the feed gas to a sulfur recovery unit. The process is automatically controlled by 70,66 so that the concentration of H 2 S in the second amine absorber is concentrated and controlled at a desired point so that the off gas has the required H 2 S/CO 2  ratio.

Abstract: This invention consists in that inside a porcelain tube (2) of a bushing (1) which employs a gaseous insulator, an insulating tube (7) is disposed with a space of small volume set relative to the inner periphery of the porcelain tube (2), and that the small space is filled with an insulating medium (9) which is deformable with a predetermined force. According to the construction, when the porcelain tube (2) has damaged, its fragments can be prevented from scattering far. The flashover of the bushing (1) can be prevented by disposing compression springs (34) in the lower part of the insulating tube (7), and the electric field distribution of the outer surface of the bushing (1) can be improved by coating the surface of the insulating tube with an electrically conductive coating material (41).

Abstract: Lead is separated from material containing lead sulfide, e.g. galena ore concentrate, by a substantially autogenous process involving establishing a pool of molten lead in a kettle, adding a metallic alkali metal, e.g. metallic sodium, to the molten lead in an amount sufficient to reduce the combined lead of the lead sulfide to metallic lead, adding the ore concentrate to the molten lead pool, and mixing together the metallic sodium, molten lead and ore concentrate. The sodium reacts rapidly and exothermically with the lead sulfide to reduce the combined lead of the lead sulfide to metallic lead and form sodium sulfide. The thus-liberated metallic lead reports in the molten lead pool, and a matte phase containing the sodium sulfide separates from the molten lead and forms on the surface of the molten lead pool. Lead sulfide from an excess of the ore concentrate, or other suitable added flux, which is usually added to the molten lead pool, serves to flux the sodium sulfide-containing matte phase to attain desired fluid and low melting characteristics of the matte phase. The process herein employs a kettle as the reactor, ordinarily the steel refining kettle of a lead refinery, is a low temperature process requiring temperatures above the melting point of lead but ordinarily not above 650 DEG  C., and does not discharge polluting SO2 into the atmosphere.

Abstract: A contact spring assembly is constructed of a planar base plate integrally formed with a pair of opposed spring legs upstanding therefrom and a separate pin-like connection part attached to the undersurface of the base plate and extending downwardly therefrom in a direction opposite from the upstanding course of the spring legs. Opposed axial ends of the base plate are formed with planar flange surfaces which extend outwardly from the adjacent ends of the spring legs. A two piece strip housing is formed with upper and lower parts which assemble together to receive the contact spring assembly suitably therein with the flange surfaces of the base plate locked against upward or downward longitudinal movement by virtue of sidewall recesses. When the connection part is pressed into the grid bore of a printed circuit board, the impression force is transferred from the upper part of the strip housing over the flange surfaces to the base plate and from the base plate to the connection part, without stressing the contact spring legs.
