Title: Improvements in centrifugal servo-motors especially for braking systems
IPC: B60T13/06
Filed: 1951-11-13
Abstract: 686,969. Brake servomotors. PIGANEAU, G. P. Nov. 13, 1951 [March 5, 1951], No. 26555/51. Class 103 (i). A centrifugally-operated servomotor, particularly suitable for operating vehicle brakes, of the type comprising two axially-spaced plates 14 and 16 of which the plate 14 is fixed axially and rotatable by a pulley 6 from a running part of the vehicle, and the plate 16 is movable axially by the action of blocks 19 moved radially by centrifugal action in guides or ribs 17 on the inner side of plates 14 and 16, is characterized in that an adjustment stop such as the screw 34, is provided whereby the axial movement of plate 16 to operate hydraulic cylinders and pistons 30, 31 connected for instance to wheel brakes, is limited. By this means the power exerted by the servomotor device for a fixed driving speed may be varied to suit operational requirements, i.e. according to whether the vehicle is lightly or heavily loaded. As shown in Fig. 1, the plate 16 acting through a thrust bearing on a support disc 23 has a spindle 26 upon which the adjustment screw 34 acts, the spindle 26 being guided in the casing 28. Fig. 3 shows an arrangement whereby the adjustment screw 34 may be adjusted remotely by a hand wheel 43 geared to a pointer 47 that gives an indication on a graduated scale. The device is driven in known manner, as shown in Fig. 2, by tilting about a spindle 3 by a pedal 10 into engagement with a driving pulley 8. The driven pulley may be in two halves 6 expanded against springs 7 to provide a variable speed ratio according to the depth of engagement by driving pulley 8.

An extension of the toggle lever 9 engages the operating pin 11 and prevents downward collapse. The linkwork is, however, collapsed upward by an arm 23 forming part of a tripping lever 20 pivoted at 19. An adjustable spring 24 acts on the lever 20 in opposition to the pull exerted by the electromagnet 22.
Patent GB-227924-A (GB)
Title: Improvements in or relating to the recovery of organic acidic substances from matter of vegetable origin
IPC: C07C51/487
Filed: 1923-10-25
Abstract: Soluble organic acids and salts occurring in mattter of vegetable origin are recovered by adding a precipitating agent, such as an alkaline-earth hydrate or carbonate, to the solution obtained by treating the vegetable matter with water, the precipitated alkaline-earth salt being then recovered from the liquid by a surface-tension separating process, such as a flotation process or a process in which the desired material adheres to a selecting surface. An example is given describing the recovery of tartaric acid from the fruit of Tamarindus indica. The fruit is pulped, the fibrous matter and seeds removed, and the pulp, having been treated, for example, with milk of lime, passed through a sieve on to a catchment surface, such as a travelling belt of cr<\>zepe rubber, to which the calcium tartrate tends to adhere.  Copper tartrate may alternatively be obtained by treating the neutralized pulp with a suitable salt of copper.  Wine lees may be similarly treated for the recovery of tartaric acid, and calcium citrate may be similarly recovered from limes or citrons, the latter application being carried out at a temperature of about 100 DEG  C.  The process may be applied also to vegetable matter containing insoluble organic salts in addition to soluble organic acids or salts, the insoluble salt and the precipitated salt being recovered together.  For example, plants of the genus Opuntia, which contain both calcium oxalate and oxalic acid, may be treated for the recovery of the total oxalate content. In an example describing this application, the plants are pulped, preferably with the addition of water, and the liquid matter separated.  The insoluble residue is made into a pulp with water and passed through a sieve to separate coarse fibres and the like.  The liquid portion of the original pulp is treated with calcium hydrate and the precipitated oxalate, having been removed by decantation or filtration, is added to the pulp prepared from the insoluble residue. The pulp is then treated with tannin and passed to a froth-flotation machine with the addition of a small amount of oil, such as sesame oil, the calcium oxalate being recovered from the froth. Specification 231,211 is referred to.ALSO:Soluble organic acids and salts occurring in matter of vegetable origin are recovered by adding a precipitating agent to the solution obtained by treating the vegetable matter with water, the precipitated salt being then recovered from the liquid by a surface-tension separating process, such as a flotation process or a process in which the desired material adheres to a selecting surface.

Title: Improvements in or relating to precooked cereal food and method of making the same
Inventor: CARMAN CHARLES R
IPC: A23L1/18
Filed: 1952-10-30
Abstract: In manufacturing a cold-set, vacuum-puffed cereal, e.g. rice, oats, wheat, farina, or hominy, which has enlarged cells, rapidly absorbs water and is free from scorching, air and other non-condensible gases are removed, e.g. by evacuation and/or purging with steam, from the cereal and replaced by an atmosphere consisting substantially of steam, the pressure of which is maintained and/or increased over a period long enough to cook the cereal and effect substantially complete gelatinization of the starch therein.  The pressure is then instantaneously reduced by shooting the cereal into a continuously evacuated zone wherein the absolute pressure is below two inches of mercury, and preferably, does not exceed this value during puffing. The volume of the cold-set puffed cereal thus obtained may be from 1 2/3 to 3 1/2 times its original volume and its moisture content may range from 10 to 15 per cent.  Rice may first be tempered with water until it contains, uniformly, 18 to 26 per cent of moisture. Rice is preferably cooked at gauge pressures between 35 and 65 pounds per square inch and puffed at an absolute pressure between 0.1 and 0.2 inches of mercury.  Puffing may bring the temperature of the rice below 101 DEG  F., preferably below 40 DEG  F.  The puffed rice has a translucent milky-white appearance, a rough outer surface which is not  case-hardened, and numerous small cavities uniformly distributed throughout its interior.  It retains at least one-third of the thiamine present in the original rice. After being immersed in water at 200 DEG  F. for about 4 minutes, the puffed rice, during the next 10 minutes, absorbs water at the rate of 22 per cent of its original dry weight per minute.  Oats may be cooked at pressures between 10 lb. per square inch absolute and 100 lb. per square inch gauge and are preferably subjected to steam pressures between 55 and 75 lb. per square inch gauge immediately before puffing.  Glycerine and sodium bicarbonate may be added to oats about to be cooked.  The puffed oats may be rolled.  Whole wheat, farina, and hominy may be cooked at pressures between 25 and 75 lb. per square inch.  The specific gravity of the cold-set vacuum-puffed rice and oats may be approximately 28.5 to 60 per cent, the specific gravity of the cold-set vacuum-puffed whole wheat and farina may be approximately 40 to 60 per cent and the specific gravity of the cold-set vacuum-puffed hominy may be approximately 40 to 75 per cent of that of the original cereal.  Removal of non-condensible gases, cooling and puffing may be effected in a puffing gun having a treating chamber, provided with evacuating and steaming devices and a purge line, and connected by a triggered door with a much larger expansion chamber.  Specification 675,292 is referred to. p

Filed: 1960-08-08
Abstract: 904,131. Boring earth &c. SCHLUMBERGER WELL SURVEYING CORPORATION. Aug. 8, 1960 [Aug. 12, 1959], No. 27474/60. Class 85. Apparatus for sampling fluid from a formation 13 comprises a body 16, 17, 18, a seal 21 on the body surrounding the initially closed end of a conduit 65, 66, 70, 72 connected to a sample-receiving chamber 73, a device 23 on the body hydraulically operated to press the seal against the formation, a perforator 59 for opening the conduit to fluid from the formation, pressure-measuring means 68 in the part 66 of the conduit, and a valve 67 to close the conduit between the parts 70, 72. When the apparatus is positioned with the seals 21, 22 opposite the formation a valve 51 is opened to permit bore fluid 15 to flow through aperture 52 to pressure means 30 which supplies amplified pressure to cylinder 33 so that the device 23 engages to formation and presses the seals against the formation. Shaped changes 59, 60 are detonated, and formation fluid flows through conduit parts 65, 66 to the valve 67. When the pressure has built up sufficiently the valve 67 is opened and the fluid flows to the chamber 73. If bore fluid enters the conduit the increased pressure closes a valve 71 to prevent contamination of the fluid sample. After the sample has been obtained a valve 36 is opened so that a valve 38 closes the chamber 73. A valve 40 is opened to allow bore fluid to enter a conduit 110 to equalize the pressures in the hydraulic system so that the springs 112, 113 retract the device 23. The valves 36, 40, 51, 67 are electrically actuated from the surface; The transducers 42, 62 are connected to dials 44, 69 and a recorder 45 to give indications of the pressures in the pipe 32 and of the formation fluid. The bore may be cased.

Title: Random fibre webs and method of making same
IPC: D04H1/06
Filed: 1970-06-08
Abstract: 1310691 Laminated fibre webs CURLATOR CORP 8 June 1970 [14 July 1969] 27523/70 Heading B5N [Also in Division D1] The non-woven webs described may be stitched to woven fabrics to form a laminate. A bulky, porous, resilient air-laid web comprises randomly orientated fibres of at least two types, one type being shrinkable, after treatment with heat, water (including steam) or sodium hydroxide solution (in the case of natural cellulosic fibres), so that the shrinkable fibres loop and curl, thereby locking together adjacent fibres. Some fibres extend substantially from the upper surface to the lower surface. The web may be needled before the fibres are shrunk. The shrinkable staple fibres, which preferably comprise 30-40% of the total, may be natural cellulose, plasticized cellulose acetate, rayon, cellulose triacetate acrylonitrile, polyvinyl alcohol, polyvinyl chloride/polyvinyl acetate copolymer, polyethylene terephthalate, polyamide, polytetrafluoroethylene or copolymers thereof, or bicomponent triacetate/nylon 6 or acrylonitrile/acrylonitrile. Continuous filaments of two types of polyvinyl chloride, the inner component being more shrinkable, may also be used. The other staple fibre may comprise less shrinkable grades of the above mentioned fibres, wool, vegetable, metal, glass or water soluble alginate polysaccharide fibres. The web may be reinforced by continuous filaments of acrylonitrile or polyester, which may be in the form of a net, or a woven scrim. Layered webs may be air-laid using the apparatus of 1,238,923. A mixture of metal, wool and shrinkable acrylic fibres from the outer randomizing chambers, and a mixture of shrinkable and non-shrinkable acrylic fibres from the centre chamber fall towards the gap between two rotating porous drums, a vacuum being applied to the inside of the drums. The web so formed is needled and then heat shrunk. In another embodiment continuous filaments are fed to the centre of the forming web at a faster rate than the web is produced. The air current carrying the filaments and staple fibres towards the rotating drums is given a perpendicular component, producing waves in the filaments in the width and thickness directions. A non-smooth surface may result from the shrinkage, or from passage of the web through a calender where one roll is heated and embossed, and has a different surface speed to the other roll. The webs may be spray-bonded.
