Title: Improvements in or relating to watery dispersions of paraffin and other waxes, bitumen, oils and fats, and their use for sizing and waterproofing paper, textile fabric and similar fibrous material
IPC: C09K23/00
Filed: 1938-04-05
Abstract: 509,174. Starch; sizes. HALWARD, A., and MURANYI, P. April 5, 1938, No. 10427. [Class 121] [Also in Groups III and VIII] Aqueous dispersions of unsaponifiable substances, e.g. paraffin wax, other natural and artificial waxes, bitumens and oils, are obtained with the aid of modified starch alone as an emulsifying agent, with glue, casein or the like as protective colloids. The starch used as an emulsifying agent is highly degraded, by means of an agent other than alkali, but not beyond the limit at which the blue iodine reaction still appears, and a small quantity of alkali, between 0.1 and 0.2 per cent of the total weight of emulsion, is added to the dispersion after the starch has been degraded. A suitable degrading agent consists of an aryl-sulphochloramide, e.g. the sodium salt of toluene-p-sulphochloramide. According to an example, the starch may be first degraded in a heated kettle, after which paraffin wax may be added, or the starch and wax may be added together. Caustic soda solution is then added, and finally the protective colloid in the form of alkali caseinate solution. The cooled mass may be added to paper pulp in the beater, the wax being subsequently precipitated by means of alum &c. The products may be used for sizing and waterproofing paper, textile fabrics and similar fibrous material.

Abstract: 1380738 Pressurized dispensing containers L'OREAL 6 March 1972 [8 April 1971]  10430/72 Heading F1R A dispenser valve is so designed that it may be used to dispense the contents of a single compartment container or be adapted to dispense from multiple compartment containers. The basic valve, shown in Fig.1, comprises a sleeve of elastic material 8 held at one end in a recess 4 and secured at the other end to a tube 7 open to a discharge duct 10 at one end and closed at the other, a lateral orifice being provided adjacent the one end of the sleeve. Pressure on button 9 distorts the sleeve 8 to expose the orifice to the interior of a container on which the valve is fitted. To adapt the valve, as shown in Fig.5, for discharging from multiple containers, cups 52a, b, c, each having secured therein a sleeve 54 and having an inlet 53, are secured together and to the boss 44. The tube 47 passes through each of the sleeves and is provided with a corresponding number of orifices 55. As shown the spacing of the lower ends of the sleeves and the orifices is such that simultaneous discharge from all the compartments takes place on operation of the valve. The spacing between the orifices and the lower ends of the sleeves may be selected Figs.7-10 (not shown) so that compartments discharge according to the depression of the tube; the button in this case can be rotatable and have abutments which co-operate with abutments on the cup 42 to limit the movement of the tube to a given position. The frictional fit of the sleeve 8 in the recess 4 may be selected so that the sleeve functions as a relief valve. The sleeve may be inserted in the recess after filling the container under pressure.

Abstract: 329,458. Round, A., and Hewitt, J. H. April 9, 1929. Table games.- In a mimic bomb dropping game which may be adapted for use with coin-freed apparatus, an aeroplane movable horizontally is caused by a player to drop projectiles into holes in a continuously moving band whose motion is substantially transverse to that of the aeroplane. The aeroplane 3 mounted on a tubular arm 4 pivoted at 5 is moved horizontally by the operation of a lever 6 outside the casing 10. Balls falling from the tube 4, either pass through one of the holes 2 in the moving band 1 into a trough 30, after which their passage operates an electrical or mechanical coin freeing device, or fall on the band which conducts them to a funnel 18 and tube 19. To release a ball for play, the pivoted lever 7 is pushed downwards causing the bent lever 24, pivoted at 25, to rise. The sprung pawl 26 presses up the column of balls 20 in the arm 4 forcing one or more past the sprung pawl 28 when they are projected on to the band 1, the pawl 29 retaining the column of balls on release of the lever 7. When coin freed apparatus is used, the insertion of a coin may cause an electric or spring motor to operate the moving target for a definite period, at the same time allowing the arm 7 to be rocked a certain number of times. A ball falling in the trough may during its return to the tube 19 release the coin or a prize.

Abstract: 569,924. Fluid-pressure servomotor-control systems. GEIGER, G. M. July 7, 1943, No. 11034. Convention date, March 26. [Class 135] [Also in Group XXXIII] Means for controlling the movement of a device, e.g. the tiller of a steering unit, includes a reciprocable cylinder 56 adapted to be operative selectively hydraulically or mechanically and locked automatically hydraulically against inadvertent movement whether actuated hydraulically or mechanically. The cylinder 56 connected to rudders 67, 68 is movable on a fixed piston and carries a valve box 34 in which a distributing valve 43 is movable by a cable 49 from the steering wheel. Pumps 10, 11, operable through one-way clutches from propeller shafts 18, 19, whereby they are inactive during astern movement of the ship, supply pressure liquid through check valves 16, 17 to the valve box. A further check valve 38 is arranged in a connection between the inlet and exhaust ports of the valve. Movement of the steering wheel operates the valve 34 to supply pressure liquid to either end of the cylinder 56, thereby moving the rudders. The valve box moving with the cylinder reestablishes the valve in its central position and locks the cylinder against further movement. In the event of failure of pressure supply, or when moving astern, an abutment 48 or 54 on the end of the valve engages the valve box after movement of the valve by the steering wheel and the cylinder is moved mechanically in the required direction. The valve can then be re-centred to lock the device, but if this is not done, inadvertent movement in one direction is prevented by the check-valve 38, and a slight movement in the opposite direction recentres the valve and effects the hydraulic lock.
