Abstract: 1,221,603. Vehicle detector. GENERAL SIGNAL CORP. 2 Sept., 1969 [10 Sept., 1968], No. 43413/69. Heading B7N. [Also in Division G4] A vehicle detector comprises a block 5 of resilient material, e.g. rubber, having a portion C disposed to be engaged by the wheel of a passing vehicle; and a switching arrangement including a magnetic reed switch and a permanent magnet disposed respectively in apertures 11, 12 formed on either side of a slit 16 joining a pair of holes 9, 10 extending through the block. Normally the magnet holds the switch contacts closed but on compression of the block by a vehicle wheel the switch and magnet move apart as the slit 16 opens and the switch opens to release a relay, Fig. 4 (not shown). The detector may be mounted on an L- shaped bracket 7 on a rail web to detect the passage of rail vehicles or a number of such detectors may be disposed in a channel extending across a roadway or a part thereof and have their switch contacts connected in series to the relay.

Title: Heat exchangers for use with steam condensers
IPC: F28B11/00
Filed: 1960-12-20
Abstract: 967,668. Condensing steam. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. Dec. 20, 1960 [Dec. 31, 1959], No. 43705/60. Heading BIB. In a system for condensing steam by direct contact with water which has been cooled by passing it through a heat-exchanger over which a stream of atmospheric air is flowing in the direction of the arrows 1, the water withdrawn from the condenser (not shown) being then recirculated through the heat-exchanger and used for further condensation, the heat-exchanger comprises two groups 13, 14 of finned parallel tubes communicating at the top by a return chamber 5, one group of tubes being behind the other with respect to the air-stream. The conduit 2 leading the warm water to the exchanger and the conduit 3 leading the cooled water back to the condenser are each connected by valves to both connections 4 and 6 of the exchanger, the valves being adjusted so that the water flows up one group of tubes while being cooled by the air which has already passed over the group of tubes in which the direction of water-flow is downwards, or the valves may be adjusted so that the water flows in the reverse direction. A water-storage tank 15 is connected to the system by conduits 16 and 17, as shown. In one way of operating, the warm water enters the exchanger through valve 10 and connection 6, and the cooled water leaves the exchanger through connection 4 and valve 7; for valves 8, 9, 18 and 19 are all closed. In order to switch-over to the other way of operating, the valves are adjusted in a sequence that prevents the pressure in the exchanger from falling below the normal operating pressure, thereby ensuring that no air enters the exchanger. Valve 7 is closed and then valve 8 is opened : valve 10 is closed and finally valve 9 is opened. An apparatus is also described wherein the valves are operated by a hydraulic system employing high-pressure oil.

Abstract: 1,205,755. Thermal storage heaters. MULTITHERM Ltd. 4 Oct., 1967 [4 Oct., 1966], No. 44261/66. Heading F4U. The casing of a thermal storage heater is cooled by a stream of air flowing in contact with its inner surface. As illustrated, a fan 17 draws ambient air through a filter 4 and a passage 6 which surrounds core insulation 5 and is bounded by the heater casing 3. Air from the fan is passed through a passage 9 in the storage core and/or a by-pass according to the setting of a butterfly valve 18. Air passes from the heater via a duct 13 for utilization in a ducted air heating system. An auxiliary fan 20 is provided to maintain a flow of air through the cooling passage to the outlet duct when the main fan is not operating. Operation of the main fan automatically stops the auxiliary fan or closes the inlet to the auxiliary fan. In other embodiments (not shown), the cooling passage and the passages in the storage core are arranged in parallel. The cooling passage may be arranged to cool less than four walls of the heater casing.

[Also in Division B1] An evaporator stage in a distillation plant, e.g. a sea water desalination plant, comprises a plurality of pairs of vertically spaced parallel plates 10 arranged side-by-side in a casing 20. The plates of each pair are mirror images of one another and define therebetween a central evaporating passageway 32. Each plate 10 has a top portion 106 bent inwardly to form both a reservoir and a convergent-divergent passage for the liquid to be evaporated, and a bottom portion 1 is kinked at 14 and doubled back to form a channel 15. U-shaped partitions 18 are positioned as shown in these channels 15 to define heating passages 33 for the heating fluid namely steam. The condensate formed from the steam condensing accumulates in the channels 15 before eventually overflowing through recesses 10d in the plates 10 into outlet passages 36. Rubber diaphragms (21, Fig. 6, not shown) are provided to seal the plate and partition arrangement along opposite sides of the casing 20. Resilient diaphragms 22a, to which pressure may be applied, vary the spacing between parts 12 of the adjacent plates as required. Rods 17 floating in the reservoirs control the flow of liquid. Each plate 10 is provided with alternately inwardly and outwardly facing dimples 16. Several such evaporator stages may be arranged in series one above the other such that unevaporated liquid from one stage falls into the reservoirs of the stage below. The excess steam and condensate of one stage forms the heating fluid to be fed to the stage below.
