Title: Safety barrier for road traffic
IPC: E01F15/04
Filed: 1962-07-03
Abstract: 1,016,135. Crash barriers. J. J.-M. J. GERIN. July 3, 1962 [July 4, 1961], No. 25463/62. Heading E1G. In a safety barrier for road traffic guiding strips 1 are mounted between rigidly anchored pillars 10 (Figs. 1 and 2) and then have at least one smooth substantially vertical face, each strip 1 having at its ends a projecting dish-shaped portion 3 or 4 which projects downward to nest in a corresponding depression either on a pillar 10 or in the end of an adjacent strip, the faces then presenting a continuous smooth face. The strip 1 and the pillars 10 are of concrete in which an embedded endless ring is a flexible reinforcement. The portions 3 or 4 are of unequal dimensions, the smaller 4 nesting into the larger 3 of an adjoining strip 1 (Fig. 2). They are assembled together in a dished member 11 in the top of a pillar 10, to pivot therein. The guiding strip 1 may be straight or curved forming two substantially vertical walls (Fig. 10c). Crutches 7 may support the strip 1 between two pillars 10 (Fig. 7). The strip 1 is pierced with weight-reducing holes 8 and is reinforced by buttresses 26, 27 with metal-reinforcement 28 (Figs. 1 and 7). The pillars may be partially embedded in the road, the portion below road level being sharply flared and partly under the road itself. The pillar may constitute two frames 15, 16 of substantially trapezoidal shape in plan when erected (Figs. 3 and 4) and may be joined laterally by solid walls. The frames 15, 16 may be reinforced with a metal cable 20 in the form of a closed ring anchored in the base and passing around the dished portion 11 where shown (Fig. 4). The pillar may be reinforced by a central strut 23 in the shape of an X (Fig. 5). A plate 24 may be inserted in a groove in the side 17 of the base of a frame 15 (Figs 4 and 5) and in a groove in the member 25 of the X-shaped strut, to be covered with earth. A modified pillar is made of two halves symmetrical with respect to the strut. The pillar may be included in the wall of a road along a ravine and fixed so that the wall of the strip is off the road. In front of each pillar shown in Fig. 10c is a pillar with a rotating indicating drum. Strips 1 at the roadside may have housings for trees.

Title: Processes of preparing bilirubin
IPC: C09B61/00
Filed: 1938-08-31
Abstract: 518,637. Hormones and the like. ARMOUR & CO. Aug. 31, 1938, No. 25483. Convention date, Oct. 1, 1937,. [Class 81 (i)] [Also in Group IV] Bilirubin is separated from admixture with bile acids and their salts by extraction with liquid chlorinated aromatic hydrocarbons in which bilirubin is soluble and bile acids and salts are not. In the example, hog bile is treated with slaked lime to precipitate bilirubin and bile acids as their calcium salts ; the precipitate is separated, dried and suspended in monochlorbenzene; to the suspension is added glacial acetic acid to liberate the bilirubin and bile acids, and further monochlorbenzene ; the solution is filtered off and concentrated for bilirubin which is further purified by extraction with alcohol. Bilirubin is used in the treatment of arthritis and in testing liver functioning.

IPC: C25C3/34
Filed: 1957-08-13
Abstract: Melts suitable for electrolysis comprising alkali metal fluoniobates or fluotantalates are prepared either by treating with hydrogen chloride a suspension of niobium or tantalum pentoxide in an alkali metal halide melt comprising an alkali metal fluoride or by heating a non-molten mixture comprising niobium or tantalum pentoxide, an alkali metal fluoride and ammonium chloride or fluoride to a reaction temperature not exceeding the sublimation temperature of the ammonium salt and after reaction raising the temperature above the melting point of the alkali metal halides present to remove excess ammonium salt, e.g. to 700-900 DEG C.  Preferably the alkali metal halide content of the melt or mixture comprises potassium fluoride alone or with potassium or sodium chloride or sodium fluoride or with a plurality of alkali metal halides.  The initial melt in the first procedure may be prepared by adding the oxide to a preformed halide melt or by heating a mixture of the components.  The oxide:alkali metal halide ratio is preferably 1/2 -\ba2/3 . The reaction is carried out in a resistant vessel, e.g. of graphite or platinum, preferably the electrolytic vessel: in an example of the second procedure the mixture was kept covered and scavenged by a vigorous nitrogen current.

Abstract: 1533302 Variable resistors WILHELM RUF KG 23 June 1976 [6 Nov 1975] 26034/76 Heading HIS [Also in Division H3] A tuner unit for controlling a radio or television provided with variable capacitance diodes has sleeves 8, Fig. 3, rotatably secured to threaded tuning spindles 5 of resistive potentiometers to form operating knobs 7, an inwardly tapered annular flange portion of each sleeve has an end surface 23 arranged to a but the rear surface of a front plate 2 adjacent an opening 6 through which the knob portion 7 is received, pivoted pointers 15 corresponding to each potentiometer have ends extending into windows 14 in the front plate and a band change switch associated with each tuning spindle has a resettable bar 13 which is displaceable to contact a selected one of fixed bars 16 interconnecting the band change switches. Each pointer 15 is coupled with the wiper nut of each potentiometer by a slot in a pivoting lever (30, Fig. 5, not shown) connected to the pointer. The rear end of each spindle 5 is secured to the housing by a spring (25, 26, Fig. 10, not shown) which engages a groove 24 in the spindle. A desired band, such as U.H.F., can be selected by pushing an end 12 attached to a wire or strip 13 into one of the detents 11 in windows 10 in the panel 1 so that the wire 13 contacts one of contacts 21 of fixed wires of strips 16 which are held in the housing by lugs 20.

Title: Improvements relating to electrostatic precipitators
IPC: B03C3/36
Filed: 1951-11-08
Abstract: 699,670. Electrostatic filters. HEINRICH, R. F. Nov. 8, 1951, No. 26156/51. Class 39(i) The invention relates to an apparatus for precipitating suspended dust particles from gases of the " Venetian blind " type in which the gas enters a conical or tapered chamber at a high velocity, the inlet being at the wide end of the chamber. The chamber walls 4 are composed of members having small gaps between them. The major part of the gas stream is withdrawn through these gaps in a direction nearly opposite to the original direction. The dust is thrown out of this part of the gas stream before it leaves the chamber by the centrifugal forces set up by the sharp change in direction. The remaining part of the gas stream together with the dust is withdrawn from the narrow end 7 of the chamber, and passed through any conventional separator 8, after which it is normally re-circulated. The invention consists in electrically charging the dust particles, in charging the chamber wall to the same sign, and in collecting the dust particles repelled from the chamber walls on electrodes charged to the opposite sign. As shown, the dust particles are charged in the zone 1 formed by electrodes 2, 5, and the collecting electrodes 6 are in line with and connected to the non-discharging electrodes 5. The collecting electrodes 6 may be composed of inclined shoots or may be plain plates. The members constituting the chamber walls 4 are curved to provide dust pockets for collecting dust particles charged to the same sign as the chamber walls. The chamber walls may be inclined to the vertical.
