Patent GB-608110-A (GB)
Title: Improvements in or relating to degreasing apparatus
IPC: C23G5/04
Filed: 1946-02-15
Abstract: <PICT:0608110/III/1> The solvent in solvent degreasing plants is prevented from being overheated by a device comprising a pressure-operated valve or switch inserted in the heat supply line to the plant, so that the heat supply is cut off when the pressure falls, together with means whereby the valve or switch is operated by the pressure head of the solvent charge in the plant.  The device may be used with gas heating, electric heating, oil-burning plants, &c., and for degreasing plants comprising vapour, liquid-vapour, or multi-liquor plants.  In one form applied to a gas-heated, liquid-vapour degreasing plant, the gas control valve 5 is of the simple two-chamber diaphragm type and is connected to the degreasing chamber 1 by means of an open-ended narrow bore pipe 3 dipping below the solvent level therein.  The pipe 3 is led outside the degreasing chamber, above the level of the condensing tubes usually arranged within the degreasing chamber, and is intermediately connected to a pump 4 through a non-return Schrader valve.  When the gas supply is turned on, the air pressure in the pipe section between the pump 4 and valve 5 is raised initially by the pump 4 to a pressure less than the pressure head of the solvent charge, but sufficient to keep the gas valve open and allow the gas to flow through to the burners. When the pressure of solvent and solvent vapour becomes less than this pressure, as the solvent level goes down, the pressure is insufficient to operate the diaphragm and the gas valve closes and shuts off the gas supply.  In a modification applied to an electrically heated plant, the gas control valve is replaced by a diaphragm and a pressure switch which latter is kept closed and the circuit completed by the diaphragm whilst the solvent level remains sufficiently high; when the latter falls, the switch is opened and the circuit broken, the heat being cut-off.  The solvent level may thus be maintained at a level above that of the usual lower thermostat which can then function normally and prevent the liquid becoming overheated.

[Class 64(iii)] In a plate type heat-exchanger having holding chambers for controlling liquid flow each formed by a closed frame of H. section providing channels in its opposite sides for receiving sealing gaskets 15 with which engage side plates 11 of the type shown in Fig. 3, the H-sectioned frames are each formed by a web 14 and two strips 12, 13, Fig. 5, the latter being of corrosion-resistant material, e.g. stainless steel, and secured to the web along its inner and outer edges as by sweating or welding. The side plates 11 are formed with flanges 19 at their edges which engage with the outer frame members 12 to prevent bulging. These flanges may-be interrupted and turned alternately in opposite directions. An aperture 16 extends across the width of each plate at the top or bottom of alternate plates when arranged for the flow in series of the liquid for holding, certain' of the plates having both top and bottom apertures when arranged for parallel or series parallel flow. These arrangements determine the holding time. Slotted lugs 17, 18 on each side plate 11 and frame 12, 13, 14 engage on rods or bars (not shown). To bye pass the heat-exchanging medium from and to .heat-exchange plates 27 which may be clamped either side of a holding section formed by a number of the holding chambers, extensions of the lugs may be formed, having ports 20 which are interconnected with liquid tight joints to form bye-pass conduits. Alternatively these extensions may be omitted and pipes connected between the heat-exchange sections.
