Converting alternating currents. - Blocking condensers are made with electrolytically conducting dielectrics to lower the a.c. resistance, the polarizing voltage being utilized to prevent the passage of direct current therethrough. As described paper dielectrics are impregnated with electrolyte or the condenser plates are given oxide or sulphide coatings. Water, alcohols, and nitrobenzol, alone or as solvents for other substances are mentioned as impregnating fluids and the condenser plates are preferably of tin or aluminium. The cells may be used singly or in series, or as shown in Fig. 1, metallic screening plates 3, 4, 5 may be interposed between the active plates 2, 6 to increase the effective polarization voltage.

Abstract: 509,213. Plate heat - exchangers; radiators for heating buildings. LUKACS, F. Oct. 17,1938, No. 29968. [Classes 64 (ii) and 64 (iii)] In a fluid heat-exchanger a number of horizontal concentric cylinders 2, 3, Fig. 1, are mounted in a casing 6, and joined at their alternate ends so as to form a corrugated partition. The two fluids enter at openings 11, 13 and leave at exits 12, 14. A baffle plate 17 inside the opening 13 directs the fluid streams between the cylinders. A number of heat exchangers may be used in series in combination with a heat storage vessel. The heat exchanger may be used in a hot water system and attached to a radiator 31, Fig. 3. Steam is passed through one compartment of the heat-exchanger 34 through pipes 38, 39. The water contained in the heat exchanger is heated and passes to the radiator through the pipe 32 and returns by the pipe 33. Two plug holes 41, 43 are arranged at different levels at the top of the radiator 31, and to fill the radiator water is introduced through the orifice 43 until it overflows from the orifice 41, which is then closed. Steam is then introduced into the heat exchanger until the maximum temperature is reached when the orifice 43 is closed, so that the interior of the radiator is at less than atmospheric pressure.

Abstract: 1332075 Rolling rod W SCHWARZ 29 June 1971 [8 July 1970 29 Sept 1970] 30439/71 Heading B3M [Also in Division E1] A concrete-reinforcing rod having a plurality, preferably four, of sinuous ribs 3, Fig. 1, or 4, Fig. 4, extending generally longitudinally of the rod, the ribs having flanks steeper than 45 degrees to the plane surface of the rod and the maximum inclination of the ribs to the axis of the rod being between 45 and 60 degrees, is produced by cold rolling the rod with rolls such that the ribs are formed, without external pressure on their crests, in the gaps between the adjacent rolls. A cold rolling mill for producing the rib pattern shown in Fig. 4 is indicated in Fig. 9, where four rollers 12, 13, 14, 15 are shown, of which the rollers 12, 14 are shown reducing the diameter of the rod 16 where two adjacent ribs 17 are at their positions of closest approach, while rollers 13, 15 are shown reducing the diameter of the rod where two adjacent ribs 17 are at their positions of greatest separation. The form of the flanks and working faces of the rollers varies continuously between those shown for rollers 12 and 13 (Fig. 6, not shown). The rollers 12-15 are preferably coupled together for synchronous rotation by bevel gearing which may either comprise teeth formed on the flanks of the rollers (Fig. 12, not shown) or consist of bevel gears secured to the rollers (Fig. 11, not shown). The phase relationship of the rollers is adjusted so as to be in phase when the pattern of Fig. 1 is to be produced.

Abstract: 1,032,009. Locking rotary elements. ETABLISSEMENTS MERLIN & GERIN S.A. Aug. 4, 1964 [July 20, 1963], No. 30527/64. Heading F2E. [Also in Division H2] A control device for electric circuit breakers comprises a spring 14 wound by hand through gearing 18, 19, and held by a pawl 20, the spring driving the breaker through a cam 24 on a driving shaft 12 acting on a follower 26 on a driven shaft 27, the shaft 12 being locked in each of its two positions (corresponding to open and closed contacts) by a brake (Fig. 5, not shown) acting upon a drum 22 attached to the shaft 12. The brake comprises a number of segments 28- 30 pivoted together and conforming over at least 180 degrees to the surface of the drum, one end segment 30 being hooked over a pawl 39 mounted on drum 22 while the other end seg. ment 28 is resiliently attached to the housing. Since the drum is tending to turn under the spring drive 14 the segments are wrapped tightly about the drum preventing its moving. The pawl 39 is mounted on an eccentric boss 40 of an arm 41 loosely mounted on shaft 12 but coupled to the drum by a spring 45; arm 41 is latched in either of two positions by pawls 43, 44. From the closed position (Fig. 5, not shown) release of pawl 43 allows spring 45 to turn arm 41 to withdraw pawl 39 into the drum, the arm 41 coming to rest against pawl 44. This releases the brake and drum 22 rotates, the pawl 39 re-emerging from drum 22 to engage a second hook portion 37 on segment 30 to apply the brake. Release of pawl 44 permits further rotation of the drum to restore it to its closed position. In a modification (Fig. 13, not shown) the segments are mounted internally of the drum (Fig. 10, not shown) or the engaging faces of the segments and drum may be serrated. Alternatively (Figs. 6-9, 11, 12, not shown) the segments may be replaced by resilient straps or chains which may be wrapped once or several times about the drum 23.
