Filed: 1958-06-13
Abstract: 837,721. Pressure cooker; timing. STOUFFER CORPORATION. June 13, 1958 [Aug. 12, 1957], No, 19030/58. Class 28 (1). [Also in Group XVIII] Vegetables placed through an end door 14 into a container 10 is cooked by steam jets 12 impinging directly on the food and building up a cooking pressure in the closed vessel 11. Dry steam is supplied from a steam trap 35 through a solenoid controlled valve 34 while condensate is first allowed to drain away through a solenoid controlled valve 47. Automatic operation is timed as follows. Dial 59 is set to the desired cooking period on scale 60, which rotates cam 56 and closes the normally open contact 65 of switch 52 and also opens the normally closed contacts 66 without effect because of the normally closed contact 65 is parallel therewith. The closing of contact 65 energizes solenoid 34<SP>1</SP> thus opening the steam valve 34 whereupon the steam jets eventually penetrate down through the food driving out the air and condensate through the open valve 47. When all the food is heated up the steam stops condensing and pressure in it builds up to expand bellows 53 to open contact 62 and close contact 70 of switch 51. Opening of contact 62 de-energizes solenoid 47<SP>1</SP> to close valve 47 while steam valve 34 remains open to build up the pressure to a predetermined value say 5 lbs. Bellows 53 are expanded to open contact 62 and close 70 to close valve 47 until full steam pressure 15 lbs. in the vessel 11. Closing of 70 energizes motor 55 of the timer which rotates the cam 56 for the period of time set by the dial knob 59. When notch 58 comes opposite to the cam follower 57, switch 52 opens its contact 65, thus de-energizing solenoid 34<SP>1</SP> and valve 34 closes to stop the flow of steam. Simultaneously, contacts 66 close to energize solenoid 47<SP>1</SP> to open valve 47 to exhaust. At atmospheric pressure the flexed door 14 is bent inwardly to allow it to be removed through the end opening having previously been flexed by the lever 20 to increase its top to bottom length to engage the flange 15.

Title: Improvements relating to the conditioning of the exhaust gases of internal combustion engines
IPC: F01N3/04
Filed: 1952-07-30
Abstract: 711,112. Washing gases. RUTH, J. P. July 30, 1952, No. 19274/52. Class 55 (2). [Also in Group XXVII] The exhaust gases of an internal-combustion engine are conditioned to a non-hazardous and unobnoxious form free from entrained solids and acidic constituents by introducing the gases under the influence of their discharge pressures into the lower portion of a liquid 11, e.g. water, which is agitated by the passage of the gases to dissolve soluble gas constituents in the liquid, and then passing the resulting gas-liquid mixture through the interstices of an alkaline diffusing medium, e.g. broken lime rock 22, which is slightly soluble in the liquid 11 and readily soluble in the acid gas-liquid mixture. The lime rock has a neutralizing effect on the acidity of the gases and the condensate resulting from the passages of the gas-liquid mixture through the lime rock is collected in the liquid 11, the undissolved gases being liberated, eg. through a conduit 23. The apparatus for carrying the invention into effect may comprise a housing 10 having an upper compartment defined by walls 15, 16 and communicating by tubes 17 with the lower part of the housing which contains the water 11 and is divided into two chambers by an inclined baffle 14. A reticulate or foraminous screen 21 in the upper part of the housing provides a backing for the lime rock fragments 22. The gases are fed through an opening 19 to the tubes 17 and into the smaller of the chambers defined by the baffle 14 and wherein the gases cause a circulation of the water 11 about the baffle. The gases rise in the form of bubbles to the surface of the water, the solid particles entrained in the gases sinking and collecting in the larger of the chambers, and then pass through the screen 21. The water vapours carried by the gases adhere to and coact with the lime rock surfaces to neutralize the acidity of the gases, the maze of passages constituted by the lime rock facilitating the release of particles travelling with the vapours and the return of such particles to the water. The gases leave the housing via the conduit 23 connected to a centrifuging assembly 26 in which the pressure and velocity of the gases are applied to generate a cyclonic effect to separate out moisture and solid particles carried by the gases and which are returned through a pipe 28 to the lower part of the housing ; alternatively, to avoid a concentration of sludge in the housing the sludge may be discharged through a branch 30. The gases are finally discharged through an outlet 27 of the assembly 26. There may be a plug 12 in the housing to determine the level of the water 11.

Title: Air conditioning means for an enclosure
IPC: B64D13/06
Filed: 1951-08-20
Abstract: 721,676. Ventilating aircraft. GARRETT CORPORATION. Aug. 20, 1951 [Aug. 26, 1950], No. 19547/51. Class 137. [Also in Group XIII] In apparatus in which air supplied to an enclosure is cooled by coolant air in a heat exchanger and by means in which energy of the air is converted into mechanical energy, air moving means (driven by the energy-converting means) and air-flow inducing means, receiving air discharged from the air-moving means, together circulate the coolant air through the heat exchanger. In the form shown, a compressor 11 delivers air to an enclosure 10 partly through heat exchangers 14, 15 and partly through a by-pass 25. The air leaving the heat exchangers passes partly through a turbine 17 and partly through a second by-pass 27. The turbine drives a fan 19 propelling coolant air leaving the heat-exchanger 15 through a duct 21 acting as an injector on coolant air leaving the other heat exchanger 14. The flow of air through the by-passes 25, 27 is controlled by valves 28, 29 moved by a torque actuator actuated by means responsive to the temperature of the air in the enclosure 10. There may be a lost-motion connection between the two valves, so that, for example, the valve 28 opens and closes before the valve 29. A check valve 24 prevents reversal of flow of coolant air through the heat exchanger 14. In another form, the heat exchanger 15 and by-passes 25, 27 are omitted, and coolant air passes directly to the fan 19 from the inlet passage 18. The outlet passage for coolant from the heat exchanger 14 contains a venturi between the heat exchanger and the injector. The venturi is stated to restrict excessive flow of coolant air. In a modification it is replaced by a valve which may be actuated automatically or manually. Specifications 604,301 and 654,678 are referred to.

Title: Improvements relating to the extrusion of fused filament-forming compositions
IPC: D01D1/04
Filed: 1943-11-24
Abstract: In the melt-spinning process for the manufacture of artificial filaments, films, foils and like materials from fused filament forming compositions, e.g. synthetic linear superpolyamides, polyvinyl compounds, and cellulose <PICT:0573326/IV/1> esters or ethers, wherein solid composition is fed into a vessel containing a heating liquid, heat being applied locally to the vessel, the composition is deflected in its passage through the heating liquid to the point of extrusion, towards the walls of the vessel or locality at which heat is applied, thereby effecting an improved and more uniform degree of melting.  The deflection is effected by a baffle in the form of a conical grid or sieve when the heating liquid has a specific gravity lower than that of the composition, or by a continuous plate, domed or conical, when the heating liquid, e.g. molten metal, has a specific gravity higher than that of the composition.  Flat grids or sieves may also be employed in conjunction with the conical baffles, and a plurality of baffles, deflecting the material alternately towards the walls and centre of the vessel may also be employed.  The method is applicable to continuous and batch spinning operations.  The fusion vessel may be heated externally by a fluid jacket or by electrical windings, and temperature regulating means may be employed.  Fig. 1 relates to a type of melt-spinning apparatus described in Specification 565,489, wherein the heating liquid 4 has a lower specific gravity than that of the composition.  Solid material is fed automatically by feeding means of the type described in Specification 573,327, through passage 32 to the melt vessel 2, and passes through heating liquid 4, whereby it is melted and forms a pool 3 at the base of the vessel.  Pump 6 withdraws the molten material and forces it through filter 8 and extrusion jet 9, means being provided, to displace the material from the pump, filter and jet, for cleaning purposes, by valve 13 and auxiliary valve 16, the device also serving to prime the pump with heating liquid.  The vessel is surrounded by jacket 24 containing a heating liquid 25.  A level-indicating device 28 of the type described in Specification 573,325 enables composition to be fed continuously to the vessel.  Conical wire mesh grid 21 terminating in cylinders 22 and 23 constitutes a baffle by which solid composition is deflected to the walls of vessel 2.  A melt-spinning apparatus of the type described in Specification 565,981, wherein a heating liquid of higher specific gravity than that of the composition is employed, is also described in which the solid material is fed upwardly through the heating liquid and deflected by continuous conical baffles first to the centre and then to the walls of the vessel, any small pieces passing the baffles being finally retained by a flat sieve until molten.
