Title: Improvements in and relating to steam boilers in power installations
IPC: F22B33/14
Filed: 1929-04-15
Abstract: 309,832. British Thomson-Houston Co., Ltd., (Assignees of Smith, A. R.). April 14, 1928, [Convention date]. Compound boilers; heating by indirect contact of steam.-the exhaust from a turbine or other engine 35 driven by steam from a high-pressure boiler 4 is condensed in a heat-exchanger 29 serving as a low pressure boiler, the condensate being returned to the high pressure boiler by a pump 39. The heat-exchanger comprises steam generating tubes 22 connected to upper and lower drums 20, 24. The upper drum is connected by steam and water pipes 30, 31 to the steam drum 11 of a low pressure boiler 10 arranged above the high pressure boiler. The raw water from which the low pressure steam is generated is fed into the drum 11 through a pipe 34. The low pressure steam is used for heating purposes. High pressure steam may be led through a, pipe 41 directly into the heat-exchanger when the demand for low pressure steam is above the normal, or when the turbine is not in use.

Abstract: 925,804. Printing-surfaces. W. RITZERFELD, and G. RITZERFELD. March 30, 1961 [April 6, 1960; April 21, 1960; May 25, 1960], No. 11720/61. Class 100 (2). [Also in Group XX] In a method of preparing a hectographic master sheet, a negative of an original is produced photographically in hardened gelatin in image-free areas of the master sheet, the unhardened gelatin at the image areas is rendered sticky by applying an aqueous solution of a compound thereto, and the master sheet is brought into pressure contact with a hectographic transfer sheet, hectographic material being transferred to the master sheet at the sticky image areas. A sheet 48 provided with a coating of light-sensitive silver halide emulsion is placed in contact with an original and laid on a transparent hood 7 beneath a blind 9 and exposed to a lamp 8. The exposed sheet 48 is passed through a developer container 5 and into contact with a roller 29 applying an aqueous solution 23 of a leuco base of triphenylmethane dye. The coated sheet is then passed between rollers 31, 32, the latter being heated, in contact with a transfer sheet 12 having a coating comprising an oxidizing agent, an acid and a precipitant, also a tanning substance such as tannin, bichromate or alum. The sheet 12 has a fold 47 to receive the sheet 48, which may be of transparent waterproof paper.

Title: Improvements in or relating to the vacuum distillation of lubricating oils
IPC: C10G7/00
Filed: 1933-04-21
Abstract: Pure lubricating oils are obtained from <PICT:0407551/III/1> <PICT:0407551/III/2> <PICT:0407551/III/3> <PICT:0407551/III/4> crude oils without acid or filtration treatment by a flash fractional distillation at a pressure below 50 mms. of mercury to obtain relatively impure distillates which are redistilled separately at lower pressure either progressively or by batch distillation, the vapours obtained being fractionated and condensed under vacuum and out of contact with residual vapours and gases.  The flash distillation unit, Fig. 1, comprises a series of fractionating towers 10, 11, 12 to the first of which the oil is delivered through a series of heat exchangers 60, 59, 97, 98 and a pipe 18 while the residual oil from the towers 10, 11 is heated in pipe coils 44, 45, and 82, 83, before admission to the succeeding tower.  The towers are similarly constructed and contain each a curved entrainment plate 241, Fig. 3, from which the vapours are deflected tangentially and with a whirling motion through screens 242, 243 while the upper parts of the towers are provided with alternate central and side plates 25, 26 connected by curved vanes.  Each tower is provided with reflux condensers 28, 29; 60, 61; 87, 88; the tower 11 having an additional condenser 59.  Trays 57, 58 &c. are provided from which the impure distillates are led off to seal tanks 32, 36, 64, 71, 79, 841, and 90.  These distillates are then redistilled in a still 110, Fig. 2, through which and heating coils 113<a> the fractions are continuously circulated by a pump 116.  The still is surmounted by a fractionating tower 111 provided with reflux condensers 123, 124 and stepped fractionating plates 112, Fig. 5, and a vacuum of about 3 mms. of mercury is maintained by a battery of ejectors 126.  The pure lubricating fraction is collected on a plate 137 and led off through a seal tank 139 to storage.  The fraction to be redistilled is admitted to the still from the redistillate tank 118 and the apparatus can be used continuously by discontinuing the firing of the furnace 113 when a residue of about 6 per cent remains in the still and circulating this residue at a reduced rate by a stand-by pump 147 through the heating coils only.  The residue is then removed from the still 110 and replaced by a fresh distillate from the tank 118 which is then used to flush out before it the residue still circulating in the coils 113.

Abstract: 372,536. Printing-machines. BAILEY, J. T. P. and THRISSELL ENGINEERING CO., Ltd., Thrissel Street, Bristol. April 21, 1931, No. 11773. [Classes 100 (i) and 100 (ii).] Tripping-arrangements.-An automatic device for stopping a printing or like machine in the event of the breakage of the web 1 comprises feelers 4 mounted on a spring- controlled shaft 2 and normally held in the position shown by the web..The feelers are connected by an arm 7 and a flat spring 8 to a trip block 9 which on breakage of the web is interposed between a rotating cam 19 and a vertical rod 18 connected to a spring latch 15. Normally the block 9 is held clear of the cam, but a spring 5 moves the block 9 into engagement with the cam when the web breaks. The catch 15 normally holds a spring-controlled rod 12 connected to the striking-gear of the press in its operative position, but when the catch 15 is released, the rod 12, Fig. 2, by means of a slotted link 12a operates a lever 11 on a shaft 10 which operates the usual belt fork or friction clutch. The shaft 10 can be operated by a hand-lever 10a to start the machine. To enable the machine to be run without paper for setting-up purposes, the feeler shaft 2 can be supported by levers 20 which put the feeler mechanism out of action temporarily.

Title: Improvements in or relating to underlays for carpets
Inventor: GRIMSHAW NORMAN
IPC: D06N7/00
Filed: 1962-03-28
Abstract: A resilient carpet underlay comprises a core of canvas or like woven material, or knitted, matted or otherwise fabricated material, having a layer of porous material (made from granules of organic material held together by a foamed rubber latex or a foamed resinous adhesive) on each side thereof.  The core may comprise a single layer of material.  The underlay is produced by foaming a mixture of a surface active agent (that is, a soap), a foam stabilizer, and a quantity of granular organic material, e.g. ground-up tyre scrap, adding to the foamed mixture a quantity of rubber latex adhesive having a flat curing characteristic or an adjustable accelerator system, coating one side of a core material with a layer of the aqueous adhesive mixture so formed and heat curing or part curing the mixture, coating the other side of the core material with a layer of the aqueous adhesive mixture and either completing the curing of the first layer together with the curing of the second layer or curing the second layer without causing overcuring of the first layer.  The aqueous mixture may be formed by mixing together a soap, casein and water, and the mixture foamed together with a granular organic material, the foaming being carried out to produce a foam having a volume approximately four times the volume of the unfoamed mixture.  The aqueous mixture may consist of 0,6 parts of soap, 0,2 parts of casein, 1,2 parts of water and 11,5 parts of granular organic material, the parts being by weight.  The casein may be a 12,5% solution in water.  The rubber latex adhesive composition may have an ammonia content of up to 0,1 parts by weight.  The ratio by weight of the foamable aqueous solution to the rubber latex adhesive may be 3:1.  The core, when coated on one side with a foamed mixture (which may have a flat curing characteristic), may be subjected to heat partially or completely to cure the coating, the core then being subjected to coating on the reverse side, and to further heat to cure the coatings without overcuring the previously partially or completely cured coating.  The core, when coated on one side with a foamed mixture having a low accelerator, may be heat treated partially to cure the coating, the core then being subjected to coating on the reverse side with a foamed mixture to which additional accelerator has been added and to further heat finally to cure the first applied coating and simultaneously completely to cure the second coating.  The coating and curing may be carried out continuously or noncontinuously.
