IPC: B41J33/14
Filed: 1973-05-03
Abstract: 1375687 Ink ribbon mechanism; cartridges SCM CORP 3 May 1973 [3 May 1972] 21111/73 Heading B6F An ink ribbon cartridge 10 has a base (30, Fig. 2) and a cover 32 and an arm 16 laterally extending from the cartridge housing for guiding the ribbon from the housing to a print point and back to the housing. The arm 16 is pivoted at an oblique angle to the base on an open fulcrum (60, Fig. 3) and is spring biased to a rest position by a spring (62). The base (30) includes a circular storage compartment (34, Fig. 2) having a hollow concentric hub 40 therein for storing the ribbon supply roll 36 freely rotatable around the hub. A take-up spool 42 rests on top of the hub 40 and has an integral shaft 44 with a gear 48 at its end which passes through the hollow hub 40 to engage a drive gear 50 in the typewriter. A friction hollow 100 on the cartridge co-operates with a drive roller 104 in the machine to pull the ribbon from the supply through the arm 16 and feed it back into the cartridge housing. The take-up spool 42 is driven via a spring belt 138 and pulleys, which permits slippage when required. A pair of geared rollers 60 and 90 are provided for regulating the ribbon tension. Roller 90 is rotated by the ribbon entering the take up spool. This roller 90 drives roller 80 via meshing gears 96 and 86. If the ribbon is taut it will frictionally engage roller 80 to be driven thereby thus decreasing tension. A slack ribbon merely allows the roller 80 to rotate without being driven thereby. The take-up spool 42 has a flexible finger 43 formed in its upper flange which co-operates with a circular detent train 47 on the inner surface of the cover to prevent unwinding. The arm 16 is the subject matter of Specification 1,375,356.

Title: A process for the polymerisation of monomers having a terminal vinyl group, in aqueous media
IPC: C08F4/06
Filed: 1961-06-12
Abstract: Vinyl monomers are polymerized in aqueous medium in the absence of free radical catalysts and using as catalyst one or more water-stable metal compounds of metals of Group VIII.  Specified monomers are butadiene, isoprene, chloroprene, styrene, vinyl chloride, acrylonitrile, acrylates, vinyl ethers, acrolein and methacrolein. Catalysts disclosed are halides of Pd, Rh, Ir, Ru, Fe; metal-olefin complexes such as rhodium cyclo-octadiene chloride, bis(cyclopentadienyl) rhodium, cobalt or nickel, palladium butadiene chloride, chlorocyclopentadienyl palladium chloride and cyclopentadiene palladium chloride; bis(mesitylene) ruthenium halides, complexes of ruthenium halides with trialkyl or triaryl phosphorus; iron butadiene carbonyl, iron nitroso halides, iron cyclopentadienyl carbonyl halides, cobalt silico fluoride, nickel oxide, cyanide and complexes thereof, hydronickel carbonyl, bis(acrylonitrile) nickel and ammonium palladium chloride.  The catalyst may be formed in situ.  Preferably the aqueous medium is free of oxygen, is purified by use of an ion-exchange resin, contains an emulsifying agent and/or alcohol, and is at constant pH. Variation of the temperature may be used to control the orientation of the products, which may range from solids (e.g. rubbery) to oils. In examples the products may be coagulated with MeOH or H2SO4 and NaCl, to give particles or crumbs which can be used in the production of tyres, belts, tubes, impregnating and coating compositions, and surfacing compositions for roads and walkways.  Specifications 734,848 and 755,183 are referred to.

Title: Improvements in free-wheeling devices for cycles, motor cars, or the like applicablealso to clutches
IPC: F16D41/28
Filed: 1919-08-29
Abstract: 154,973. Feuerheerd, E. Aug. 29, 1919. Clutches, friction.-In one-way friction clutches, of the type in which an annular wedge-shaped member is forced into an annular wedge-shaped recess, one bounding wall of which is formed by the eccentric periphery of a loose ring, the wedgeshaped member acts as the driving-member, while the driven member is an outer hollow cylindrical member co-operating with the loose ring to form the wedge-shaped recess. In the application to free-wheel mechanism for cycles, the annular wedge 9 is connected rigidly to the driving- sprocket 1, while the recess is formed between the flange 2 of the driven wheel and the periphery of a loose ring 5 which is shaped like a snail cam and retarded by a spring 11 mounted on the driven member. Rotation of the driving-sprocket moves the wedge in the direction of the arrow to engage the clutch, while the member 5 is retarded by the spring. On the driver ceasing, the driven member 2 overruns the wedge by reason of its momentum and so removes the spring from the step of the cam. The member 5 then follows the rotation of the member 2 and releases the clutch. ln some instances the spring 11 may be omitted and the inertia of the member 5 relied on to secure the engaging and disengaging movements.

Abstract: 1,076,510. Fluid-pressure servomotor systems, fluid regulation. ROLLS-ROYCE Ltd. May 13, 1966, No. 21483/66. Headings G3H and G3P. [Also in Division F1] . gas gas turbine engine is provided with means for shutting off fuel flow when surging conditions arise in the engine compressor. As shown, an engine 10 has a low pressure compressor 12 and high pressure compressor 13, some of the air from the compressor 12 being by-passed via duct 14 and mixed with the exhaust gases from the turbines (not shown). A fluid switch 21 has its power nozzle 20 supplied from compressor 13 via line 15 and filter 16, and the control nozzles 28, 31 are supplied from compressor 12 via line 26 and filter 27, a capacitor 29 and restrictor 30 being provided upstream of nozzle 31. During normal operation, the jet from nozzle 28 is more powerful than that from nozzle 31 and the power jet is deflected into exhaust line 22. If surge-promoting conditions arise, i. e. the output pressure from compressor 12 falls rapidly, the jet from nozzle 31 deflects the power jet into line 23, whereupon positive feedback via line 32 and nozzle 34 maintains this deflection of the power jet. The pressure rise in line 23 moves piston 25 leftwards against spring 66 and the piston unseats a disc 62 via grooved tappet 64. Fuel from a chamber housing a piston valve 39 leaks to an exhaust port 50 causing a pressure difference across the ends of valve 39 which moves rightwards against spring 56 to abut a collar 53 and cut off the main communication between fuel inlet 40 and outlet 41. A restricted passage 47 in valve 39 maintains pilot fuel flow. A valve 35 actuated by the pilots throttle lever is closed when the pilot selects reduced fuel flow and in the closed position valve 35 closes feedback line 32, separates chamber 24 from line 23 and vents chamber 24. The power jet is thus deflected back to line 22 and the fuel valve 39 opens.
