Patent GB-385092-A (GB)
Title: Improvements in or relating to sheet feeding mechanism
IPC: B65H3/10
Filed: 1931-12-03
Abstract: 385,092. Feeding sheets. KIDD, D. B. and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Dec. 3, 1931, No. 33511. [Class 100 (i).] Sheet - separators; pile supports.-In sheetfeeding apparatus the magazine 11 is attached to a slide 12 which is reciprocated in guides 13 by means of a rack 14 engaged by an oscillating pinion driven by a sector gear 16 which is oscillated by a cam on the main shaft 19 of the apparatus. The sheets are withdrawn from the magazine by the action of two suction rollers 20 formed with suction apertures which extend over about a quarter of the periphery of each roller. The separation of the sheets is assisted by the sagging of the bottom sheets in the centre due to their being not supported at the central portions. The front edge of the pile is supported by a ledge 22, and the plane in which the bottom sheet reciprocates is tangential to the rollers 20. The separation of each sheet commences when the pile is at its extreme position to the left, and as the pile moves to the right to the position shown in Fig. 2 more suction orifices come into operation, and the whole of the front portion of the sheet is gripped before the rearmost portion of the sheet is pulled from the pile. The sheets are withdrawn from the rollers 20 by strippers 29 engaging in grooves 27 on the rollers, and guides 28 then control the sheet. The air pressure in the roller apertures is controlled by a pump 24 and pipe 25. Fixed shields 26 provided inside the drum are attached to conical supports 126 and extend around the greater part of the periphery of the drum to close the suction holes during the greater portion of their angular movement.
Patent GB-417116-A (GB)
Title: Improved method and apparatus for indicating the density and colour of smoke from furnaces
IPC: G01N21/29
Filed: 1934-02-15
Abstract: 417,116. Smoke-indicators for furnaces. PETERSEN, K., Buddinge Vaerk, Buddinge, Denmark. Feb. 15, 1934, No. 33511/32. [Class 51 (i).] In smoke-indicating apparatus for furnaces, the smoke is led from the furnace flue system to the indicator 2 at increased speed, this speed being reduced, during passage through the indicator itself, to a value less than that of the speed'of the gases through the furnace flues. As shown in Fig. 1, the smoke is drawn through the pipe 1 by an air injector 13 supplied by a fan 10, the reduction in speed in the indicator 2 being effected by making the latter of considerably greater cross-sectional area than the pipe 1. The indicator comprises a glass cylinder 3 fitted between the base 7 and top 4, the latter being vertically adjustable with respect to the cylinder 3. To guide and steady the smoke stream 8 and to prevent blackening of the glass 3, compressed air is supplied from the fan 10 to inlets 6, the air passing upwardly through a gauze 5 surrounding the smoke inlet chamber 2. Fig. 2 shows a modification in which the indicator is disposed in a byepass 17, 18 in the main smoke passage 16, there being provided, in this case, a second fan 19 to maintain the circulation through pipe 1, passage 16, and return pipe 20. The indicator is maintained at a sufficiently high working temperature by the provision of electric heating elements, a thermostat being fitted to cut out one or more of the elements when the working temperature has been reached and simultaneously to start up the fan motor 9. Several constructions of indicator which may be used instead of the direct observation device 3 are described. In one construction, Fig. 3, a rod 22 is movably mounted in the smoke conduit 21 so that its end 23 may be passed through an aperture 24 into contact with a moving faintly-coloured band 25 upon which there is thus made a mark indicating the soot content of the smoke. In another form, the smoke conduit is formed with two oppositely disposed apertures in front of which are respectively mounted a source of light and a travelling light-sensitive film. Fig. 4 shows a construction which may be used both for recording and for direct observation, the smoke being delivered by nozzles 26 along both faces of a rotary porcelain or like disc 27 which is enclosed at its upper part by sight glasses. The soot deposited on the disc serves to record the character of the smoke and is removed during rotation by brushes 31 disposed in a water tank 30. Further constructions are described in which soot is separated from the smoke current and deposited for observation on a moving band or a water stream. Fig. 7 shows an indicator of this form, the soot being separated in a rotary drum 38 by a water jet 41 and baffles 42 and passing off with the water to a gutter 43 in which it is examined either directly or by means of a mirror 37.

Title: Improvements in the manufacture and production of insulating materials
IPC: C08J9/30
Filed: 1934-11-22
Abstract: Solutions of urea-aldehyde condensation products are converted into foam by mechanical treatment while adding foam-forming substances as such or as a pre-made foam, and this foam is hardened to form a heat-insulating material.  Acid foam forming substances are preferred, such as alkylated naphthalene sulphonic acids, or chloral hydrate which splits off acid on heating; neutral substances such as reaction products of alkylene oxides with high molecular weight alcohols, such as polyethylene glycol ethers of octodecyl or octodecenyl alcohols, or the sodium salt of p  N-methyl oleyl taurine may be rendered acid; or the foam may be hardened by treatment with gaseous acids, as sulphur dioxide. According to an example: 4ccm. of butylated naphthalene sulphonic acid and 40 ccm. of water are stirred into a foam.  800 ccm. of a 32 per cent solution of a urea-formaldehyde (1 : 2) condensation product is stirred in, and the foam is moulded, preferably in a mould with perforated walls, and allowed to set.  Evaporation of water should proceed slowly to maintain the foam structure.  The number and size of cells may be controlled by varying the strength of condensation product solution, by varying the duration and speed of stirring, and the amount of foaming agent.  Pigments such as iron oxide red, yellow, or black, chromium oxide green, chrome yellow, umber, carbon black, or dyestuffs as crystal violet, or Sirius red b b , may be added, or the surface only may be coloured.

Abstract: 621,954. Gas turbine plant. MASCHINENFABRIK OERLIKON. Dec. 3, 1945, No. 32670. Convention date, Oct. 10. [Class 110(iii)] A thermal power plant consisting of a steam boiler plant and a gas turbine plant the working medium of which is produced by the combustion of fuel in a combustion chamber has the gas turbine plant so designed that the amount of exhaust gas is greater than the amount of air required for combustion in the steam boiler plant when in normal operation and a part of the exhaust gas of the turbine plant serves as combustion air for the grate of the steam boiler and another part of the exhaust gas serves to preheat the feed water of the steam boiler plant. The air for combustion in the furnace of a steam boiler plant is supplied by the exhaust gases from a combustion gas turbine 9. The air supplied by the compressor 8 is pre-heated in the exchanger 11 heated by the exhaust gases from the turbine 9 before passing to the combustion chamber 10 the gases from which drive the turbine 9. The steam from the boiler may be used in a condensing turbine 62 or in a back pressure turbine 61 and a heat consumer 7. The excess exhaust gases from the turbine 9 are used to preheat the feed water for the boiler in a heat exchanger 42. The stack gases from the boiler may also be used to preheat the feed water. The gases leaving the heat exchanger 42 may be used in an' external heat consumer 71. The heat exchanger 11 may be omitted. Specifications 375,597 and 459,365 are referred to.

Title: Improvements relating to the production of aryl alkyl sulphones
IPC: C07C317/14
Filed: 1962-09-03
Abstract: Pure aryl alkyl sulphones are made by subjecting substantially equimolar amounts of aluminium chloride and alkane sulphonyl chloride and an excess of an aromatic hydrocarbon or halogenated aromatic hydrocarbons to a Friedel-Crafts, reaction at a temperature substantially in the range 70-80 DEG  C., for 7 to 12 hours, recovering the excess of the aromatic reactant and separating the aryl alkyl sulphone. The excess aromatic reactant may be recovered by distillation under reduced pressure and the sulphone isolated by cooling the reaction mixture, pouring the mixture on to ice and hydrochloric acid, extracting the sulphone with ether and distilling the solution, preferably at a pressure at or below 0.1 mm. mercury. Examples describe the preparation of p-fluorophenyl ethyl sulphone, p-fluorophenyl methyl sulphone and p-chlorophenyl ethyl sulphone.

Title: Noise discriminating circuitry and method for electronic particle study apparatus
IPC: G01N15/12
Filed: 1972-07-19
Abstract: 1394182 Particle analyzers COULTIER ELECTRONICS Ltd 19 July 1972 [22 July 1971] 33824/72 Heading G1N [Also in Division H3] A particle analyzing apparatus includes a noise discriminator circuit which discriminates against signal rise time so that noise signals which have faster rise times than the data pulses are excluded. The output from the particle analyzer is applied to the reset input R of a 4 - chip binary counter of the discriminator and to a low threshold circuit the outputs of the discriminator and threshold being connected to respective inputs of a gate connected to a pulse height analyzer, Fig. 1 (not shown). During the time t 0  - t 1 , Fig. 3 which shows data pulses 30, 32 and noise pulses 34-42 the counter 50 is reset by the trailing edge of the pulse so that from t 1  to t 2  clock pulses are fed to the counter 50 since no blocking signal is applied to invertor 54 from the 4Á sec. output of the counter and gate 52 is enabled. Since the period t 1  to t 2  is less than 4Á sec. which is the set rise time threshold the clock does not advance the counter up to the 4Á sec. output and no output is obtained therefrom. From t 2 -t 3 the counter is again cleared by the reset signal and from t 3 -t 4  clock pulses again feed into the counter. Since this rise time duration is greater than 4Á sec. there is an output at the 4Á sec. terminal which via invertor 54 inhibits NAND gate 52 and also is fed to the gate connected to 46. However since the pulse 36 is of smaller amplitude than the threshold 14 of the low threshold circuit the gate is not enabled and no pulse is applied to the pulse height analyzer. The counter is again reset from t 4  to t 5 . When the pulse 30 arrives not only is the rise time sufficiently long for an output at 46 but its amplitude is great enough to exceed the threshold level 14 and the gate is enabled to pass the pulse to the pulse analyzer. Similarly noise pulses 38-42 have insufficiently long rise times to produce an output at 46 whereas data pulse 32 does and has an amplitude greater than 14.
