IPC: D06B3/10
Abstract: 131,940. Mond, A. Sept. 30, 1918. Coating-appliances, hand. - An appliance for doping aeroplane fabrics comprises a closed dopecontainer provided with a valve-controlled outlet for the fluid, a distributing roller mounted beneath the container adjacent to the outlet, and a plurality of rotary spreading brushes for evening the coating driven by the roller. The arrangement may be such that the dope falls on the distributing roller and is thence transferred to the fabric, or the dope may be fed by a spout on to the fabric direct, and the rotary brushes may be driven from a jockey roller mounted in advance of the brushes. An appliance constructed according to the latter arrangement is shown in Fig. 1. Dope is delivered from the container a by a spout x on to the fabric F and is evenly spread by the rotary 'brushes s<1>, s<2>, s<3>, which are driven in opposite directions successively, as shown, by belting t<1>, t<2>, t' and gearing y<1>, y<2>, z<1>, z<2> from the jockey roller w, to which acetone or other solvent is fed from an auxiliary container a<1> so as to prepare the fabric for the easy penetration of the dope. The container may be fitted with a partition v and air pressure may be applied at the valve r to adapt the device for use in an inclined or vertical position. In a modification shown in Fig. 3, the distributing roller e is mounted between, and projects beyond, the rotary brushes s, s<1>, and the container is rocked after each backward or forward stroke to bring each brush alternately into operative position. The roller and brushes may be mounted on a frame f removably attached to the container. Means may be provided, as shown in Fig. 4, for allowing a number of such doping appliances to be operated at the same time. The handles c are connected by easily detachable means such as bolts and fly-nuts to a cross-bar 1, which is reciprocated by a bar 2 and provided with guiding means, such as vertical extensible rods with wheels running on rails on the ground or overhead. All the rollers may be driven from a single revolving shaft extending along the cross-bar and provided with sprocket wheels, pulleys, or chain drive, the shaft being revolved by hand-operated gear.

Patent GB-804486-A (GB)
Title: Dentifrice compositions containing stannous tin compounds
IPC: A61Q11/00
Filed: 1957-04-25
Abstract: A dentifrice containing a stannous compound capable of supplying at least 10 but not more than 1000 parts per million of stannous ions when in association with water, and being present in said dentrifce in an amount sufficient to provide an amount of undissociated said stannous compound which will not immediately dissociate completely to form stannous ions when associated with water, and which will preferably maintain the above concentration of stannous ions as the dentifrice ages.  Such compounds are the slightly water-soluble stannous compounds of which the condensed phosphates, e.g. pyrrophosphate and metaphosphate are preferred, although stannous tartrate, maleate or citrate may be used.  The presence of such compounds and in such concentration as above is said to provide a maintained pH level of 3.5 to 6.0 which results in better flavour retention, taste and film formation than before, and particularly when incorporated in fluoride containing dentifrices enhances the anti-dental caries properties of such compositions.  Many fluorine containing compounds may be incorporated in the compositions according to the invention including: SnF2, NaF, SnF4, KF, InF3, PdF3, FeF2, LiF, Na2SiF6, CaZrF6, Na2ZrF6, K2ZrF6, KSnF3, NaBF4, SnClF, Sn2ClF3 and fluorotitanates.  Other sources of stannous ions that may be included in the compositions are SnSO4, SnCl2 and stannous gluconate.  Conventional dentifrice adjuvants which may be included are abrasives, e.g. calcium orthophosphate and alumina, insoluble condensed phosphates, e.g. calcium pyro- and metaphosphates and sodium metaphosphate, and the slightly soluble stannous compounds essential to the compositions may replace, at least in part, the above abrasives: sudsing agents, e.g. the water-soluble alkyl and alkyl ether sulphates and sulphonates in which the alkyl group has 8 to 18 carbon atoms, water-soluble salts of sulphonated monoglycerides of fatty acids having 10 to 18 carbon atoms, water-soluble sulphated fatty alcohols having 10 to 18 carbon atoms, salts of fatty acid amides of taurine, e.g. sodium-N-methyl-N-palmitoyl taurine, salts of fatty acid esters of isethionic acid, or substantially saturated aliphatic acyl amides of saturated aliphatic monoaminocarboxylic acids containing 2 to 6 carbon atoms and in which the acyl group contains 12 to 16 carbon atoms, e.g. sodium-N-lauroyl sarcoside: thickeners, e.g. water-soluble salts of cellulose ethers, gum karaya, arabic or tragacanth, colloidal magnesium aluminium silicate and silica: humectants, e.g. glycerin and sorbitol; flavours, e.g. oils of wintergreen, peppermint, spearmint sassafras and anise; saccharin, dextrose, lerulose and sodium cyelamate.
Patent GB-133450-A (GB)
IPC: G03B9/08
Abstract: 133,450. Williamson, C. M. Oct. 10, 1918. Aeronautical apparatus; cameras for roll-films and with connected action between shutter and changing mechanism.-In cameras designed more particularly for use on aircraft and of the type in which a train of gearing operating the filmchanging and shutter mechanism in driven either by means of a separate power unit, an air-screw, or manually, a cam-groove on the face of a gearwheel in the train of gearing controls the film and shutter-setting mechanism and coacts with an arm controlling the shutter to operate the shutter or permit the release of the shutter when the parts have been set for a fresh exposure. The cam-wheel also controls two capping flaps and operates to open these at the moment of exposure. In the apparatus for releasing the shutter by hand, the cam-groove 6, Fig. 1, on the face of the gear-wheel 5 has an inwardly-extending portion 6<a> and engages a pin 7 on the shutter-controlling arm 8, which can be actuated from outside the camera when the pin 7 is in the portion 6<a> of the groove. The wheel 5 has a mutilated gear 16 and is on a shaft 18 with two other gear-wheels 19, 22, Fig. 3, likewise mutilated and which set the shutter 133 and wind the film spool 24 respectively. The wheels 19, 22 are out of gear with the respective gear-wheels 20, 23 when the parts are in position for exposure, and the shutter is held set by a trip arm 13, Figs. 1 and 4, engaging a ratchet-wheel 14 on the shutter shaft. In this position, the mutilation 16 of the wheels 5 disconnects this wheel from the driving-gear, comprising the wheel 4, worm-wheel 3, and the worm 1 on a shaft 2, which may be coupled with an air-screw or other source of power. The wheels 3, 4 may be coupled by a ratchet connexion, so that the wheel 5 may be independently driven by hand. After actuating the arm 8 to make an exposure, the return movement of the arm under the influence of the spring 17 moves the wheel 5 forward through the pin 7 and re-couples up the gearing. The pawl 52 co-acting with pins 53 prevent backward movement of the wheel 5. When the wheel 5 with its cam 6 is in position for exposure, two flaps 30, 31, Fig. 6, are opened to expose the film area for exposure, and the film gate 25 is closed. The flaps are mounted on arms 39 and are raised by crank-pins 28, 29 on the wheels 5, 22 respectively, which depress spring- controlled arms 26. 27. These arms actuate the flaps through pins 33 and link-work 35, 37, 38, and also pull down the gate 25, which is normally held away from the film by springs 32, 41. The arm 27 actuating the overlapping flap 30 is shaped at its end 40 so that the other flap 31 may fall first after an exposure, thereby preventing the edges of the flaps from fouling each other. In apparatus for continuous running, the shape of the cam-groove on the wheel 5 is modified as shown at 44, Fig. 8, and the gearing of the wheel 5 is not mutilated.

Abstract: 967,844. Zone-melting. SIEMENS-SCHUCKERTWERKE A.G. April 6, 1962 [April 11, 1961], No. 13463/62. Heading B1S. [Also in Division H5] In the formation of a single crystal rod by zone-melting or crystal-pulling, the crosssection of the melt being crystallized is deformed to correspond to the natural crosssectional shape of the crystal. In the case of silicon or germanium, the cross-section is an equilateral triangle when the axis of symmetry is the (111)-axis, a square when the axis of symmetry is the (100)-axis, and a rhomb when the axis of symmetry is the (110)-axis. In the case of zinc or cadmium, the cross-section is a hexagon when the axis of symmetry is the (0001)-axis. In the case of potassium chloride or tungsten, the cross-section is a triangle or rectangle. Deformation may be by the use of heated argon or helium (Fig. 1), an electrostatic field (Fig. 3), or an electromagnetic field (Fig. 4). The electrostatic field may be formed by the application of a potential difference of 10 kV. in a vacuum or protective gas atmosphere. The electromagnetic field may be formed by feeding a current of 10 kc./s. into an induction coil fed with a heating current of 4 mc/s., the coil having the shape shown in Figs. 5 or 6. The coil may be of silver-plated copper tubing internally cooled by liquid or gas. Different methods of deformation may be combined. Deformation may be effected in the last passage only of a molten zone. Specifications 888,148 and 889,160 are referred to.
