Title: Improvements in carded fibrous materials
IPC: D04H1/64
Filed: 1948-03-15
Abstract: 644,648. Agglutinated fibrous materials. BRITISH RUBBER PRODUCERS' RESEARCH ASSOCIATION, and BLOW, C. M. March 15, 1948, No. 7748. [Class 140] Carded fibrous materials of animal fibre such as wool, or vegetable fibres such as cotton or jute, or waste natural or artificial material such as rayon, are improved as regards tensile strength, permanent resilience, and stable disposition of the fibres against migration by treating the carded fibre in thin web or sliver form, preferably as it leaves the carding engine, with a spray or mist of dilute stabilized rubber latex or the like, in such a manner as to deposit discrete droplets on the web, the amount of liquid or the number of droplets being insufficient to produce a continuous film of liquid over the surface of the fibrous material, and evaporating the moisture content from the droplets leaving minute rubber particles effecting bonds between adjoining fibres at their points of intersection, but not forming a continuous film of rubber over the surface of the material. The latex may be natural rubber latex, or an aqueous dispersion of natural or synthetic rubber-like material, vulcanized or vulcanizable, and including stabilizers permitting it to be used in dilute form, with preferably less than 10 per cent solids content. A cationic stabilizer such as an alkyl ammonium halide, which renders the charge on the rubber particles positive, or an anionic stabilizer such as an alkyl sodium sulphate or sulphonate or a non-ionic type such as a fatty alcohol ethylene oxide condensate may be used. Drying may be effected by passing the treated web over steam or hot water pipes or electrically heated elements, or by infra-red radiation from above. The latex may be pigmented to increase heat absorption. Successive webs may be superposed to form a multiple layer, either before or after drying. Specification 497,793, [Group V], is referred to.

Filed: 1917-05-31
Abstract: 117,827. Sperry Gyroscope Co., and Minorsky, N. May 31, 1917. Speed indicators, gyroscopic. - An improved method of and apparatus for steering ships comprises the employment of a gyroscope so mounted as to precess in response to yawing movements of the ship, the gyroscope casing being free to swing against a constantly acting force about a horizontal axis arranged at right-angles to a vertical plane containing the centre line of the ship, movement of the casing being communicated to a pointer. The casing A is mounted so that the gyroscope axis a is parallel to the centre line of the ship, and adjustable springs a<2> are provided to resist the turning movement of the casing about its axis a<1>. The angle through which the casing moves against the springs is proportional to the angular velocity of thq ship due to deviation from the course, and in the example shown this is indicated by a pointer B moving over a scale B<1> and operated by a step-by-step motor B<2> controlled by a switch C rotated by a motor C<1>. Driven by the motor C' is an eccentrically mounted pinion C<x> engaging a toothed quadrant C<2> loose on one of the pivots a<1> of the casing, the pinion being so mounted as to give a more open scale near the zero point. Rigidly attached to the casing is an arc C<3> having conducting segments c, c<1>, separated by a strip of insulating material c<2>, in contact with which is a roller c<3> on an arm c<4> carried by the segment C<2>. The circuit of the motor is so arranged that it is driven in opposite directions when the roller is in contact with the segments c, c<1> respectively.

Title: Improvements in or relating to step-by-step controlling mechanisms
IPC: G05G7/02
Filed: 1942-06-09
Abstract: 557,941. Controllers. WYCLIFFE FOUNDRY CO., Ltd., and BARRETT, G. June 9. 1942. No. 7879. [Class 38 (iii)] [Also in Group XXIV] Consists in a step-by-step controlling mec'hanism applicable, for example, to the changing from one set of gear wheels to another or to moving an arm from one electrical contact to another. As applied to the moving of a pinion 1 to a series of predetermined positions along a shaft 2, a slider 3, 4 engages the pinion and is mounted on a shaft 5 parallel with the shaft 2, Slidably mounted in guides 6, 6a is a selector bar 7 having a series of holes 8a ... 8g corresponding in number and pitch with the positions to which the slider is to be moved. The bar 7 has a pin 15 engaging a slot in a disc 14 integral with a spring-loaded plunger 11 provided with an actuating handle 10. A pin 9 on the slider is adapted to enter one or other of the holes in the bar 7 when the latter is thrust towards the slider, e.g. by pressing on the handle 10 or a knob 21. The bar is held parallel to the shaft 5 and disconnected from the slider when pressure is relieved by spring-loaded plungers 17, 17a. The movement of handle 10 is limited by an extension 22, thereon engaging stops 25, 25a, Fig. 3, in a gate 23, which has spaced gaps 24, 24a, and a lip 26. When the extension 22 is below the lip the bar 7 engages the pin 9 and when above the lip the bar and pin are disengaged. The actuation is therefore a downward movement of extension 22 through one of the gaps 24, 24a. Then a rotary movement of handle 10 to move the slider and finally an upward movement of extension 22 through the other gap to free the slider from the bar. The movement of the slider may be rectilinear or angular and the spacing of the holes equal or unequal. Specification 529,506, [Group XXIV], is referred to.
Patent GB-1098060-A (GB)
Title: Improvements in or relating to fuel supply devices for internal combustion engines
IPC: F02D9/00
Filed: 1966-02-23
Abstract: 1,098,060. Spray carburetters. SOCIETE INDUSTRIELLE DE BREVETS ET D'ETUDES S.I.B.E. Feb. 23, 1966 [Feb. 24, 1965; March 18, 1965], No.7961/66. Heading F1B. The fuel supply is cut-off, or reduced, at overrunning by means 71, Fig. 10, responsive at 70 to intake manifold suction and at 74 to a pressure or suction which varies with engine speed. In Fig. 10 the diaphragm 71 controls a valve 8 in the idling fuel passage 4. An air pressure responsive to engine speed is produced in chamber 74 by an engine driven pump 26. During over-running conditions the high suction at 73 downstream of the throttle valve 2, acting in chamber 70, combined with the air pressure in chamber 74, overcomes spring 69 and valve 8 closes passage 4. When the speed drops to idling the reduced pressure in chamber 74 permits spring 69 to re-open passage 4. In Fig. 1 the pump pressure acts through pipe 25 on a second diaphragm 19 actuating a valve 20 which is normally open to admit atmospheric pressure to the suction space 14 and prevent closing of valve 8. At over-running the pump pressure closes valve 20 and diaphragm 11 closes valve 8. Alternatively Fig. 4 (not shown) the pump 26 may produce a suction in pipe 25 instead of a pressure and in Fig. 5 (not shown) a suction actuated valve (39) renders the diaphragm pump inoperative during normal running. In a constant suction type carburetter, Fig. 8, the diaphragm 11, controlled by suction through pipe 15 and pump pressure through pipe 25, actuate a valve 67 in a suction passage 60 leading to the suction chamber 53 controlling the air piston 46. During normal running and idling the valve 67 is closed and the piston 46 is controlled by the suction in space 48 transmitted through orifice 49. At over-running, valve 67 opens and the high suction at orifice 59 modifies the suction in chamber 53 to lift the piston 46, reducing the suction at the fuel orifice 56 and thereby reducing or cutting off the fuel. In Fig. 15 the fuel cut-off valve 8 is actuated by a solenoid 86 controlled by a diaphragm 71a subjected through pipe 75 to the pump pressure, the inlet or delivery valve of the pump being controlled by a diaphragm responsive to manifold suction in pipe 72.
