Filed: 1931-01-21
Abstract: A modification of the process described in the parent Specification characterized in that cellulose, materials containing cellulose or other carbohydrates, or the transformation products, derivatives, or "albuminous products" thereof are caused to react with gaseous alkylene oxide under reduced pressure or partial pressure obtained by dilution with an indifferent gas. The reaction may be carried out in the presence of a basic agent such as an alkali or a tertiary amine. Suitable initial materials mentioned are wood, straw, starch, glucosamine, and chitine.  The vapour of alkylene oxide may be caused to circulate through the reaction vessel and may be suitably heated or cooled to regulate the temperature of the reaction.  The following examples are given: (1) Comminuted sheets of regenerated cellulose are treated with ethylene oxide vapours under reduced pressure.  (2) A current of nitrogen is passed continuously over alkali starch and gaseous propylene oxide is gradually introduced.  (3) Waste regenerated viscose is subjected to a vacuum and gaseous ethylene oxide is introduced in stages.  (4) Straw is treated with caustic soda and after ripening, ethylene oxide is caused to circulate over it under reduced pressure.  (5) Sawdust is made plastic with zinc chloride solution, washed with caustic lye and with a solution of calcium hydroxide.  It is then caused to react with ethylene oxide under reduced pressure.  (6) Cotton linters are impregnated with dimethylaniline in ether and treated with ethylene oxide under reduced pressure.  (7) Sulphite cellulose is treated with trimethylamine dissolved in benzene, and after distilling excess benzene is placed in an autoclave through which a current of nitrogen is caused to circulate.  Gaseous ethylene oxide is slowly added to this gas current.

Title: Improvements in and relating to type-wheel typewriters
IPC: B41J1/32
Filed: 1933-01-24
Abstract: 393,224. Typewriters. UNGER, A. A., 19, Eichenstuckstrasse, Dresden, Germany. Jan. 24, 1933, No. 2245. [Class 100 (iv).] Index type-wheel machines.-In machines comprising a swinging type-wheel gearing with a sector connected to a setting-member which is movable over an index-plate and is depressed to swing the type-wheel for impression, the index-plate can rock about an axis parallel to the platen, and the setting-member connections consist of linkage so arranged that the setting-member is movable in directions tranverse to and parallel to the platen, but only the latter movement is effective to turn the type-wheel. In the machine shown in Figs. 1 and 2, a type-wheel 16 is secured to a sleeve 13 mounted on a shaft 12 which is secured to a frame 9 arranged to rock on trunnions 10, 11 on the base 2. A pinion 14 on the sleeve engages a sector 29 which can rock on a pivot 31 secured to a post 30 on the base. An indexplate 40 having indexed recesses 41 is secured to a plate 39 which can rock on trunnions 37, 38 on the base and is connected by links 45, 46 to the frame 9.

Filed: 1928-01-24
Abstract: 305,798. Gear Grinding Co., Ltd., Orcutt, A. H., and Starry, J. W. Jan. 24, 1928. Balancing. -- In a gear-grinding or other machine tool having a reciprocating slide b carrying a grinding wheel c or other tool and mounted on a vertical guide a, a weight d is connected to the slide so as to hold it with uniform pressure in all positions against its guide. A rope or chain i passes over a pulley f on the weight and over a pair of spaced pulleys e, the ends being each connected to one arm of a bell crank g pivoted on the slide. The other arms of the bell cranks are connected by fixed radius rods h to a stationary part. Thus the weight not only counter-balances the weight of the slide but also serves, through the constraint of the radius rods, to hold the slide against its guide. According to the Provisional Specification a single end of a rope may be connected to a single bell-crank on the guide or the rope may be directly connected. in an oblique position to the. slide. In a further modification two independent weights may be used, one for counterbalancing the slide and the other for holding it against the guide.

Title: Improvements in or relating to a regulating valve for braking arrangements in power driven vehicles having explosion motors
IPC: B60T15/10
Filed: 1927-01-26
Abstract: 277,542. Badertscher, O. J. Nov. 19, 1926, [Convention date]. Fluid-pressure.-A regulating-valve, Fig. 1, on a motor vehicle which serves for alternately supplying atmospheric air and the underpressure of the suction pipe to the brake cylinder actuating the brake has a differential piston 7/8 arranged in the bore 2 of the casing 1 to which an atmospheric conduit 3, a suction conduit 4 and a brake cylinder conduit 6 communicate, the differential piston being influenced by a spring 10 interposed between the piston 7 and an actuating-organ 16 adapted to displace the piston and controlling the braking action in such a manner that the underpressure in the brake cylinder is automatically kept constant with any adjustment of the valve. A spring 12 is interposed between the piston 8 and a perforated cup 13 for returning the differential piston into its position of rest; the spring 10 is stronger than the spring 12 and has an initial compression which approximately corresponds to the resistauce which the spring 12 generates at the beginning of the compression. The lever 16 is actuated through a throttle control hand-lever G, Fig. 7, and the movement of the lever G through the range g regulates the supply of gas to the engine from a maximum to the cut-off which occurs at the commencement of the range n. As the lever turns through the range n the arm 16 presses on the cup 11 and displaces the differential piston into a position in which the admission of atmospheric air from the conduit 3 is cut off by the piston 7; as the suction port is not yet opened no braking action takes place. If the gas lever is now turned into the part b of the range B, the arm 16 further displaces the piston 7/8' and compresses the spring 12 to open the suction conduit 4 to the conduit 6 to operate the brakes. The unbalanced pressure on the piston 8 now moves the piston to close the conduit 4 to the brake cylinder until leakage losses in the cylinder reduces the underpressure and thereby the braking action. The spring 10 then moves the piston to the right to re-open the suction port and maintain the braking pressure. For emergency braking the lever is turned directly into the position N, whereby the suction port is fully opened. The lever 16 may also be actuated through the accelerator pedal so that for a given adjustment of the gas lever to limit the maximum braking effect the control of the gas supply and of the braking is effected by means of the accelerator. The regulating-valve may also be acted upon by another actuating- organ instead of being actuated by the hand gaslever or the accelerator. Specification 267,889 is referred to.
