Title: Improvements in or relating to pneumatic braking installations for rail vehicles
IPC: B60T15/56
Filed: 1961-04-10
Abstract: 983,866. Compressed air brakes. KNORRBREMSE G.m.b.H. April 10, 1961 [April 9, 1960], No. 12858/61. Heading F2F. In a compressed-air braking installation for rail vehicles of the kind in which a reservoir 7 on each vehicle is maintained charged by a filling line 27 whenever the pressure therein is sufficient but can also be charged from a main line 1 via a relay valve 3 of known type during release of the brakes should the pressure in line 27 fall below the pressure in line 1, the relay valve controlling the supply of air to, and its release via an orifice 13 from, a brake cylinder 5, in accordance with the pressure in line 1, a further relay valve 17 is provided which controls a second orifice 19 whereby whenever the pressure in line 27 is less than the normal pressure in line 1 the orifice 19 is shut off to give a slow release, whereas when the pressure in line 27 is normal, the orifice 19 is connected in parallel with the orifice 13 to give a quick release. By this means it is ensured that reservoir 7 is always recharged when the brake is fully released. The normal pressure of the filling line 27 is arranged to be higher than the normal pressure in line 1, a pressure-reducing valve 39, incorporating a check valve, being interposed in the line connecting line 27 to the reservoir to prevent overcharging. The relay valve 17 comprises a piston 29, acted on in a direction by atmospheric pressure and a spring 23 to close a valve member 35 for shutting off the orifice 19, and in the other direction by the pressure of line 27 acting in chamber 25.

Title: Improvements in fabric printing machines
IPC: B41F17/00
Filed: 1926-05-25
Abstract: 269,746. Calico Printers' Association, Ltd., and Haworth, J. May 25, 1926. Tripping-arrangements. - In a fabric-printing machine wherein a tappet shaft e controls the operation of the printing-rollers the drive of the shaft e from a continuously driven wheel a is effected by the engagement of axially movable bolts i in the wheel a with radially movable bolts f on a sleeve d keyed to the tappet shaft e, the bolts i, f being provided with independent operating means. To rotate the shaft e intermittently the bolts f are extended by moving a collar h which moves the bolts by means of bell cranks g. These bolts are then caused to be engaged intermittently by a pair of bolts i, which are moved to the left against the action of springs j by means of a pair of projections p on a disc n, which is reciprocated axially by a striker actuated by a cam driven by a chain t and controlled by a clutch. When the cam permits, a spring &c. l moves the disc n into the position shown in Fig. 1, and lugs m on a disc k rotating with wheel a engage lugs q on the disc n causing the lugs p to protrude a pair of bolts i and the tappet shaft e to be thereby driven. If intermittent rotation of shalt e is not desired, the disc n is held permanently in its left hand position, and the drive of shaft e is controlled solely by radial movement of the bolts f.

Title: Isomerization of 1:4-dicyano-2-butene to 1:4-dicyano-1-butene
Filed: 1948-05-21
Abstract: 1 : 4-Dicyano-1-butene is obtained by treating 1 : 4-dicyano-2-butene by itself or in a solvent having a dielectric constant at 18 DEG  C. above 10 with a hydrogenating metal at an elevated temperature.  The hydrogenating metal is defined as a metal below calcium in the electromotive series and which acts as a hydrogenation catalyst, e.g. manganese, zinc, chromium, iron, cadmium, cobalt, nickel, tin, lead, copper and silver.  The solvent is preferably a neutral hydroxylated solvent, e.g. water or a lowmolecular weight alcohol of up to four carbon atoms. Other specified solvents in addition to those used in the examples are butyronitrile, dicyanoethane, isobutanol, acetamide, ethylene glycol, acetone, cyclohexanone, benzaldehyde and m-chloraniline. A liquid having a limited solvent power may also be used as solvent, e.g. mixtures of water with ethanol or acetonitrile and preferred solvents are those having a neutral to basic reaction. The reaction is preferably operated at above 50 DEG  C. and more preferably at between 60 DEG  and 150 DEG  C.  The reaction may also be carried out in a closed vessel above the boiling-point of the solvent but is preferably effected at atmospheric pressure.  If desired, the 1 :4-dicyano-2-butene may be fed continuously over a fixed bed of the hydrogenating metal such as copper, nickel or cobalt.  When no solvent is used the reaction necessitates the use of a high temperature such as 140 DEG  C.  In examples: (1) a solution of 1 : 4-dicyano-2-butene in absolute ethanol is refluxed with copper powder yielding a mixture of the trans and cis isomers of 1 : 4-dicyano-1-butene, which may be separated by fractional distillation; (2) the reaction is effected in water at 100 DEG  C., copper powder being used; (3) acetonitrile and copper powder are used at the boiling-point of the acetonitrile; (4) and (5) the isomerization is effected in absolute methanol and ethanol respectively at reflux temperature using an alloy-skeleton cobalt (prepared by treating an alloy of cobalt and aluminium with caustic soda as in U.S.A.  Specification 2,257,800; (6) reaction is effected in pyridine at 105-110 DEG  C., using zinc dust; (7) nitrobenzene and copper powder are used at 120-140 DEG  C.; (8) 1 : 4-dicyano-2-butene without added solvent is stirred with copper powder at 140 DEG  C., the reaction product being then filtered and distilled to yield 1 : 4-dicyano-1-butene.
