Abstract: 1452415 Vehicle wheel rims MICHELIN ET CIE (COMPAGNIE GENERALE DES ETABS MICHELIN) 29 July 1974 [30 July 1973] 33462/74 Heading B7C A vehicle wheel rim 1 for use with a tubeless pneumatic tyre comprises a pair of tyre bead retaining flanges 9, 10, tyre bead seats 6, 14 adjacent the flanges, a base 5 between the seats 6, 16 and a well 8 to facilitate tyre fitting adjacent the flange 9 having a sidewall forming an extension of this flange, a removable flexible and extensible annular member 2 being fitted in the well 8 so as to fill the well and form the bead seat 14 and a rim portion 15 connecting the seat 14 to the base 5, at least the radially outermost portion of the member 2 being made of a material which is compressible without variation in total volume. In use seating of a bead 3 of a tyre on the seat 14 causes compression of the member 2 in the region of the seat which in turn results in radial expansion of the member 2 in the region of the portion 15 so that the latter forms an abutment restraining the bead 3 from axially inward movement. The well 8 may increase, Fig. 1, or decrease, (Fig. 5, not shown), in width from its base to its mouth, or may be of the same width throughout its depth (Fig. 4, not shown). Alternatively, Fig. 2, the wall of the well 8 adjoining the flange 9 may be formed with a shoulder 26, the member 2 being shaped accordingly to fit the walls of the well. Circumferential ridges or grooves 16 may, as shown in Fig. 1, be provided on the base of the well to prevent the member 2 twisting or turning on itself in the well. The member 2 may be a one-piece member of rubber or alternatively, as shown in Fig. 2, may be formed of a rubber layer 24 and a synthetic plastics layer 25. A tyre inflation valve may be fitted in a bore which extends through a wall of the well and through the member 2 to terminate at an opening in the portion 15 (Fig. 6, not shown).

Abstract: 1441736 Refining cadmium PREUSSAG A G METALL 25 Oct 1974 [13 April 1974] 46308/74 Heading C7D Crude cadmium is continuously refined by evaporation in a vacuum and passing the vapour through a reflex condenser to remove the higher boiling point impurities prior to condensing and collecting the purified Cd. The apparatus used comprises an inverted  U-shaped steel vacuum chamber 20, with a first and second legs formed by an inclined transition portion 34. In the first e.g., an evaporator portion 22 with a heating jacket 28 leads to a reflex condenser 30 containing a helical baffle 56 and surrounded by a temperature adjustable jacket 32. The outlet of the reflex condenser 30 connects with transition portion 34 which is connected to a condenser 36 in the second leg. A temperature adjustable jacket 38 surrounds condenser 36. A vacuum tube 42, connected to a pump, extends to just above the outlet end of the second leg and has the largest possible diameter to permit a minimum annular space 50 between the tube 42 and the wall of chamber 20 to give the maximum condensing surface. The free end of the second leg feeds via pipe 44 into a heated receiver 46. The crude liquid Cd input to the first leg is from a heated vessel 10 through tube 12, a further tube 16 leading from the first leg to a heated distillation residue container 14, the heights of tubes 12 and 16 being arranged such that the residue cannot feed back into the input tube. The materials in vessels 10, 14 and 46 act as barometric locks. In operation, the pressure and temperatures are adjusted and crude Cd is sucked into evaporator 22 via tube 12. The evaporated vapour passes into the baffled reflex condenser where impurities and some Cd condense and flow back counter current to the ascending vapour, this further purifying the gas. The distillation residue is discharged into receiver 14. The remaining gas passes through the transition portion 34 into condenser 36 in the second leg where it is condensed and collected in vessel 46.

Abstract: A plate type condenser with a plurality of heat transmitting plates assembled face-to-face to form therebetween passages for steam and the cooling liquid alternately. The plate has in a heat transmitting surface, on which condensate occurs successively, a plurality of longitudinal grooves which serve for subjecting the condensate to flow down only in the grooves under the action of surface tension, and a condensate collecting and discharging means consisting of inclined grooves and vertical grooves, for the purpose of preventing the downflow liquid layer on the heat transmitting surface from its growth. The longitudinal groove is curved at the lower portion thereof along the inclination of the inclined groove, and the inclined groove is in the multi-stripes configuration to improve the condensate collecting and discharging performance. Decrease in pressure loss of steam is also accomplished in addition to the advance of the condensate discharging performance by constructing the inclined groove in the form of weir with a weir plate which is provided on the steam passage side thereof with a plurality of overhangs opening in the direction of the stream of steam.

Abstract: An arrangement for protecting ignition means in an internal combustion engine includes a cylinder head and two longitudinal parallel valve cover banks mounted thereon. Between the valve cover banks there is a longitudinal space for ignition means to the respective combustion chambers of the engine. Such a space and ignition means with their connections located therein are usually subjected to dirt, which reduces the functional reliability of the engine. To eliminate this and to facilitate engine service, the space is formed as a trough with a bottom and two end walls in the cylinder head, the trough being covered by a lid joining on to the valve cover banks and to at least one of its end walls and having at least one opening for ventilation and drainage.

Abstract: Sealed lead-acid storage cells are described, characterized by positive electrode means comprising one or more positive electrode assemblies. Each electrode assembly in turn comprises two positive electrode members lying in spaced apart relationship to one another and having an electrolyte reservoir located therebetween. In this manner it may be insured that sufficient electrolyte is present in the cells to more fully utilize the active material of the positive and negative electrodes, while still allowing the separators lying between the positive and negative electrodes to be as thin as possible and to be less than fully saturated with electrolyte. This less than fully saturated condition provides paths for oxygen transport between the positive and negative electrodes, thus facilitating recombination of oxygen, which may be evolved at the positive electrodes during charging, at the negative electrodes.
