Title: Driving arrangement for rotary superchargers for internal combustion engines and particularly for aircraft engines
IPC: F02B33/00
Filed: 1930-01-16
Abstract: 349,438. Change-speed gearing. FARMAN, H. and FARMAN, M., (trading as FARMAN, H. ET M.), 149, Rue de Silly, Billancourt, Seine, France. Jan. 16, 1930, No. 1587. Convention date, Jan. 25, 1929. [Class 80 (ii).] A charging fan for an internal-combustion engine is driven through a change-speed gear with three or more speed ratios. A shaft 3, Fig. 1, connected to the engine crank shaft, carries a wheel 4 with a set of teeth 6, and driving a second toothed wheel 5 through a friction clutch to limit torque transmitted. The lowest speed ratio is obtained when the fan shaft 30 is driven from the teeth 5 through the toothed wheel 55, ratchet clutch 42, 43 toothed wheel 47 and a ring 29 on the fan shaft. Medium speed is obtained by driving from the teeth 6 through wheel 112, ratchet clutch 111, 110, friction clutch 15 .. 20 and toothed ring 28 with toothed ring 29. The friction clutch comprises a driving plate 17, two drive plates 15, 19 and interposed discs 20. The clutch is closed by the centrifugal action of the weights 21 on the levers 23, which bear on pegs 24 carried by the plate 19; it is held open by a hand-actuated ring 25 bearing against tails 26 or the levers 23. The high speed drive is effected from two trains of gearing each starting from the teeth 6, Fig. 3, and comprising a friction clutch 95. 96, 97, and a toothed ring 108 in gear with the ring 29 and on the fan shaft. These friction clutches are of the same kind as described with reference to the medium speed, and distribute the load when driving between the two trains of toothed gear. The two trains are arranged on opposite sides of the main shaft 3, the levers 53, Fig. 2, for actuating the clutch-release rings 105 being moved together from a lever and spindle 61 through a differential gear 56, 57, 58 ; alternatively the two are moved together through a simple linkage gear. The medium gear clutch-release ring 25 is actuated from the spindle 61<1> through a lever 53a. The ratchet clutches provided in the medium and low speed trains allow the driven wheels of these trains to rotate with the toothed ring 29 when the high speed train is in use. The spindles 61, 61<1> are turned by separate levers 65, Fig. 6, each with a cam end 64 which moves an arm 62 on the spindle through a roller; the roller is held against the cam by the spring of the clutch. Specification 288,173, [Class 80 (ii), Gearing, Variable-speed &c.], is referred to.
Patent GB-353390-A (GB)
Title: Improvements in or relating to ammonia manufacture
IPC: C01F11/06
Filed: 1930-01-17
Abstract: A mixture of barium oxide and dibarium silicate, made by heating barium carbonate with carbon and dibarium silicate at a temperature of 800 DEG  C. or over, is heated, after addition of carbon, to about 900-1600 DEG  C. in nitrogen, and in the absence of air and carbon dioxide, to form barium cyanide.  The product after cooling to about 250-500 DEG  C. is treated with steam at ordinary or increased pressure to give ammonia and barium carbonate, which after addition of carbon can be re-used.  The dibarium silicate may be wholly or partly replaced by other substances such as alumina, or ferric or chromium oxides, which render the mass porous and infusible and which may or may not be capable of forming infusible barium salts.  Silica, introduced as an impurity with the carbon, may be removed periodically by known methods, e.g. by solution in alkaline carbonate or by treatment with carbon dioxide and extraction of the gelatinous silica so formed with caustic alkali.

Title: Improvements in friction clutches
IPC: F16D13/08
Filed: 1923-01-19
Abstract: 213,707. Hemmer Ges., L. P. Jan. 19, 1923. Additioit to 166,901. Clutches, friction.-The epicyclic controlling- gear described in the parent Specification is modi- - fied to enable the torque to be measured and to adapt the clutch for coupling an auxiliary motor to a shaft driven by a main motor. The freelyrevoluble discs e carrying the planet pinions g, meshing with the brake ring k and sun wheel h, carry also a similar set g<1>, meshing with a ring k<1> and loose sun-wheel h<1> and disposed alternately with the pinions g, as shown in Fig. 2. The sunwheel h is fixed on the drum i, which is keyed to the driven shaft l and is surrounded by the clutch coil b, driven at one end by the pulley a and secured at its other end by a pin d to the sunwheel h<1>. The ring k<1> carries a spring-balance arm p connected to a recording-drum q. Application of brake blocks o sets up a drag on the coil b, a torque on the wheel h, and a reaction on the ring k<1>. When the speeds of the wheels h, h<1> are equal, slip between the parts k, o ceases. The torque transmissible by the clutch is limited by the pressure of the blocks o and is recorded on the drum q. By interposing a one-way clutch between the members h, i, an auxiliary motor driving the pulley a can be coupled to the alreadyrotating shaft l only when the brake blocks o are applied and the speed of the pulley tends to exceed that of the shaft.

Title: Improvements in sanitary napkins
IPC: A61F13/15
Filed: 1956-01-18
Abstract: 820,734. Catamenial appliances. JOHNSON, R. W., MORTIMER, R. J., and ASHTON, W. H. Jan. 18, 1956 [Jan. 18, 1955], No. 1763/56. Class 81 (2). A sanitary napkin is moulded to a curved shape to conform to the shape of the body, so that no creasing occurs in use, and it is stabilized to retain its shape. The absorbent insert 10, Fig. 3, is preferably flat and wide at the front, Fig. 4, fairly thick at the mid-point, Fig. 5, and of reduced width and thickness at the rear, Fig. 6, the whole pad being of tapering width from front to rear and curved longitudinally to follow the body line. The form of the pad may be made by compressing a rectangular block of absorbent material into a mould, to which heat is applied so that thermoplastic fibres incorporated in the pad maintain the form of the pad after it has been removed from the mould. Instead of using a proportion of thermoplastic fibres in the pad a thermoplastic resin may be sprayed on to the fibres during the formation of the pads, or, in a further modification, a laminated pad may be made from alternate layers of cotton and thermoplastic fibres.

Patent GB-641284-A (GB)
Title: Production of polymeric materials
IPC: B29C48/08
Filed: 1948-01-21
Abstract: <PICT:0641284/IV (a)/1> Articles, particularly sheets, of polymeric materials having at least one smooth surface are produced by causing a liquid or paste containing one or more compounds having the group CH2=C<to flow so that it forms a smooth upper surface under gravity and subjecting it to the polymerizing action of heat, light and/or a catalyst when beneath an adjacent surface heated to a temperature sufficient to prevent condensation of any compound volatilized from the liquid or paste.  The adjacent surface is preferably heated to a temperature from the boiling point to 20 DEG  C. above the boiling point of the highest boiling volatile constituent in the liquid or paste, and the space between the liquid or paste and the adjacent heated surface is preferably substantially free from oxygen The compounds having the group CH2=C< are preferably in the liquid state at normal atmospheric temperature and pressure, preferred compounds being methyl methacrylate, styrene, vinyl acetate, diglycol dimethacrylate, allyl methacrylate, diallyl oxalate and the compounds described in Specifications 581,251, 588,660, 595,881, 596,467, 599,837, 606,716 and 606,717. Plasticizers such as tricresyl phosphate or dibutyl phthalate, fillers, reinforcing materials such as fabrics, dyes and pigments may be incorporated.  The process may be carried out by causing the liquid or paste to flow onto a moving surface which carries it through a polymerization zone, which moving surface may be made of metal and supported on a liquid or may be the upper surface of a liquid which will not mix with the liquid or paste, and which may be spread on the upper surface of a metal plate or band.  In a preferred process a continuous flexible metal band 1 is supported and driven by drums 2, 3 which also drive gaskets 4 to provide side-walls for the trough in which polymerization takes place.  A hollow chamber formed by trough 6 and a cover therefor has slots 9, 10 one at each end through which pass the metal band 1 and the gaskets 4, the metal band being supported on brine delivered to trough 6 through pipe 11 and flowing out through slot 10 and p dropping into a funnel 12.  The cover over trough 6 is heated by means of an electrical heater 14 so that its inner surface is raised to a temperature about 10 DEG  C. above the boiling point of the highest boiling volatile constituent of the liquid or paste, e.g. to a temperature of 110 DEG  C. when polymerizing methyl methacrylate. Liquid or paste to be cast passes from storage tank 15 through slot 9 at such a rate that a substantially constant level thereof is maintained on the band 1.  Heat activation may be effected by inserting infra-red lamps inside the hollow chamber above the liquid or paste being cast and in the case of photo-polymerization suitable sources of radiation may be installed inside or outside this chamber. The rate of polymerization and the rate of movement of the band 1 are adjusted so that polymerization is complete before slot 10 is reached.  Specifications 491,739, 622,374 and 626,155 also are referred to.
