Abstract: 1,197,659. Thermal regenerators. AIR PREHEATER CO. Inc. 12 Dec., 1968 [14 Dec., 1967], No. 59193/68. Heading F4K. In a rotary thermal regenerator of the type having a rotor 10 divided into sector shaped compartments containing heat transfer material 14 by radial partitions 11, heated air leaves the regenerator through a rectangular outlet duct 18 which is subdivided by a partition member 22 into two duct sections 24, 26 each having offtakes (not shown) provided at the end walls 19, 23 for the respective heated air streams. The partition member 22 is shaped so that the duct 24 communicates with the area 27 and duct 26 with the area 29 above the rotor. The hottest heated air from the rotor entering the duct 18 at A therefore mixes with the relatively colder heated air entering at B so that the average temperature of the heated air in the duct section 24 is substantially the same as that in the duct section 26 which receives its heated air from the area 29 viz. the heated air entering at C and D.

Abstract: 1358452 Scraped surface chillers MARUZEN OIL CO Ltd 28 Dec 1971 60264/71 Heading B1G In a chiller including a scraper to remove crystals formed on an indirect heat exchange surface the use as the heat exchanger surface of a machined surface having a surface roughness not greater than 12.5-S as defined in Japanese Industrial Standard B0601-1970, (quoted in the Specification). A preferred chiller is shown in the figure wherein a feed material, e.g. a mixture of C 8  aromatic hydrocarbons, via an estimation pump 4, a conduit 3 and pump 2 is continuously introduced into a double-tube type chiller 6. The mixture is cooled by indirect heat-exchange with a coolant circulated through conduits 7 and 8, whereby crystals, e.g. p-xylene are formed and remove by a scraper (not shown). The slurry, e.g. containing p-xylene crystals, is then passed into another double-tube type chiller 11 wherein further crystallization takes place. The resulting slurry is then passed to a holding tank 14, then to a first centrifuge 17, from which crystals therefrom are withdrawn at 18, whilst mother liquid pass via conduit 19 either back to the feed liquid or to an isomerization zone for conversion of isomers to p-xylene. If the crystals withdrawn are required to be very pure, they are passed to a melting tank 20, heated by coil 21, from which molten p-xylene is passed into chiller 23. The resultant slurry via conduit 25 is centrifuged at 26, and pure crystal, e.g. of p-xylene, recovered via 27, whilst the mother liquor passes through conduit 28 back to the initial feed liquid. Examples are given of temperatures and times for the recovery of p-xylene from mixtures of C 8  aromatic hydrocarbons.

Title: Indicating faults in solid state switching circuits
IPC: H03K17/082
Filed: 1979-10-11
Abstract: A switching circuit has a solid state power switch (9) (e.g. a PNP or MPH transistor or a VMOS p- or n- channel device and three individual sensing circuits (2, 3, 4) are set to indicate whether a predetermined operating characteristic of the switch (9) (e.g. the voltage across it) is greater or less than a given threshold value and thus to indicate if a fault is present in the switch (9) or the load (M) it supplies. Digital logic circuit means comprising three logic circuits (5, 6, 8) produce two digital signals from the output signals of the sensing circuits respectively indicating if a fault exists and if it is a serious fault or not. A circuit (7) comprising gating means disables the switch (9) in the event of a serious fault and a delay circuit (33, 34) is provided associated with the logic circuit means to prevent current surges due to short circuit faults being confused with normal operating current surges in switch on. <IMAGE>

Patent GB-2042806-A (GB)
Title: Starter switches for discharge lamps
IPC: H05B41/08
Filed: 1979-12-19
Abstract: A resistive heater coil 18 is connected in series with a glow starter switch in a discharge lamp circuit, in particular a fluorescent tube circuit, and is situated on the outside of a glass bulb 16 of the switch, between the bulb 16 and an outer canister 17. When the lamp fails to start and the switch flashes the resistor 18 heats the switch to a temperature sufficient to cause the starter to remain closed after flashing for about 30 seconds and then to stay closed for as long as the supply is connected. When the supply is disconnected the starter reopens in about 11 DIVIDED 2 minutes. The continuous closure of the starter has less deleterious affect on the ballast than continuous flashing. The arrangement is simpler and more economic to manufacture than a known arrangement in which the heater is inside the starter bulb, and is more readily adaptable for lamps of different wattage ratings. <IMAGE>

Title: Water heating arrangements in stoves
IPC: F24B1/183
Filed: 1980-02-04
Abstract: Open-stoves and fires generally have inner and outer spaced casings (2,3:4,5) around the hearth area (33) and the flue-gas channel (32). The space between these casings is divided into at least two sections (10, 11) so that air can flow up the stove in one section and down the stove in the other section. The air flowing through the space absorbs heat, and one or more pipe systems (35), through which a liquid flows, are arranged to be heated by the air. The pipe system (35) may be mounted in the space or in a closed unit (44 Fig. 5) mounted in proximity to the stove. <IMAGE>

When the roll is reciprocated axially, the slit strips become engaged between consecutive separators and retained by the roller (42). Once the strips are properly located between the separators, roll reciprocation is stopped. <IMAGE>
