Title: Process of preparing artificial silk from viscose according to the so-called centrifuge system
IPC: D01D7/02
Filed: 1929-10-16
Abstract: Apparatus for making filaments and films.-In the production of artificial silk from viscose by the centrifugal spinning process, the guide funnel is kept filled or substantially filled with liquid. Vibration of the thread between the godet and funnel is thereby prevented and a uniform product is obtained; further the liquid assists the draw-off and enables thicker cheeses to be made, even with a long trajectory.  The guide funnel is provided with a small lateral pipe connected by a rubber or other flexible tube to a liquid container whereby a constant head of liquid is maintained in the funnel.  The liquid may be such as to prevent shrinkage of the thread in the bowl of the centrifuge; or it may be a fixing liquid. Depressions or cavities in the bottom of the bowl lead to outlets for the liquid which is returned to the funnel.  Using a spinning bath containing 10 per cent sulphuric acid, 17 per cent magnesium sulphate and 9 per cent sodium sulphate, the liquid which is thrown off by the centrifuge and which is introduced into the funnel contains 3-4 per cent sulphuric acid, 12-13 per cent magnesium sulphate and 10-11 per cent sodium sulphate.  When using a coagulating bath only, e.g. a solution of 10 per cent ammonium chloride, 1/4 -1 per cent sulphuric acid and 10 per cent sodium sulphate, the liquid thrown off by the centrifuge has approximately the composition 7-8 per cent ammonium chloride and 11-12 per cent sodium sulphate together with a little ammonia; to this liquid is added sulphuric acid to obtain a liquid of composition 5 per cent sulphuric acid, 5 per cent ammonium chloride and 8 per cent sodium sulphate which liquid is introduced into the funnel and converts the coagulated thread into cellulose hydrate.

Title: Improvements in or relating to the production of -ß-substituted carboxylic acid anilides and their derivatives
Inventor: HOFSTETTER EMIL
IPC: C07D295/15
Filed: 1954-11-01
Abstract: Carboxylic acid anilides of the general formula <FORM:0781193/IV (a)/1> in which R is an unsubstituted or substituted phenyl group, R1 is a hydrocarbon residue, e.g. an alkyl group, and R2 is a monoalkylamino residue or (except when R is a substituted phenyl group) an N-piperidyl group, are made by reducing the corresponding a :b -unsaturated compound with aluminium amalgam.  The reaction is preferably carried out in an organic solvent, suitably in an alcoholic solvent such as methanol, and at room temperature.  The b -substituted carboxylic acid anilides may optionally have one or more substituents such as alkyl, alkoxy, nitro, amino or halogen substituents, in the benzene nucleus.  The monoalkylamino derivatives obtained by the above process may be alkylated to form the corresponding dialkylamine compounds.  In examples: (1) b -ethylamino crotonic acid anilide is reduced with aluminium amalgam to b -monoethylaminobutyric acid anilide which is treated with ethyl bromide to give the corresponding diethylamino compound, and (2) b -piperidino-crotonic acid anilide is reduced as in (1) to b -piperidino butyric acid anilide.  Specifications 726,864, 754,924 and 755,203 are referred to.

[Also in Division F2] In a door operating device the linkage interconnecting a rotatable door driving pin 3 and a door driving or controlling means 1, 11 having a linear stroke comprises a lever arm 13 secured to the pin and pivoted to a link 6 which is in turn pivoted to a further lever 5 at a pivot 4 on the further lever serving as the point of articulation between the further lever and the means, the further lever being rotatable about a fixed pivot 7 on operation of the means and the arrangement being such that at one end of the stroke of the means the pivots 4 and 7 and the pivot 14 between the lever arm 13 and the link 6 are at least approximately in alignment. Preferably the means comprises an hydraulically operated piston and cylinder adapted to open the door, a spring 2 being provided to close the door. Alternatively, the device may be used in an ordinary door closer. The end position of the piston stroke, and consequently the nearness of the lever 5 and link 6 to dead centre, can be adjusted by means of a stop ring 16 screwed on to the cylinder 11 to abut a stop pin 15 on the piston rod. The same effect can be achieved by adjusting the position of the pivot 12 on which the cylinder 11 is mounted, or by adjusting the pivot 7 transversely to the lever 5. The pivot 7 is eccentrically mounted on a baseplate (not shown) so that it can also be adjusted in the direction of the length of the lever 5 to alter the angular position of the door pin 3 and thereby adjust the closed position of the door. The device may be rotatably mounted in an assembly box or frame.

Title: Braking mechanism for motor vehicles with trailers
IPC: B60T13/58
Filed: 1952-12-19
Abstract: 706,310. Tractor-trailer braking systems. SUDWERKE MOTOREN-UND KRAFTWAGENFABRIKEN GES. Dec. 19, 1952 [Dec. 21, 1951], No. 32237/52. Class 103(1) [Also in Group XXVII] In a braking mechanism for a motor vehicle with a trailer, the motor vehicle having a subsidiary brake which is operable independently of its friction brakes, the actuating device of the subsidiary brake is so coupled to the trailer brakes that the trailer is automatically braked when the subsidiary brake of the motor vehicle is applied. The normal braking system of the tractor-trailer system comprises a main compressed air reservoir 2 which is connected by pipe 3 to a pedal or hand lever operated main braking valve 4 from which pipes 5 and 6 lead to the front and rear brake cylinders of the tractor vehicle. Connected to the main braking valve 4 is a conventional trailer compressed air braking system; a pipe 7 being connected to the control valve 11 of the trailer via a shut-off cock 8, a coupling 9 and a hose 10. The control valve 11 is connected by a pipe 12 with a trailer compressed air reservoir 13 and by pipes 14 with the brake cylinders 15 of the trailer wheels. The tractor vehicle is provided with a subsidiary braking system by which the manually or electromotively operated actuating device 16 rotates the cam shaft of the engine 1 (a two-stroke engine with continuous current scavenging) of the tractor vehicle in such a way as to cause the engine to operate as a compressor. The actuating device is connected by linkwork 18, 19, 20 to a fine regulating valve 21 provided in the conduit 22 which connects the main reservoir 2 with the control valve 11 of the trailer brakes via a pressure limiting valve 26 and by-passes the main braking valve 4 of the tractor vehicle. Thus the tractor vehicle is subsidiarily braked during long descents, by the engine which acts as a compressor, the trailer being braked in the normal way but controlled by the subsidiary braking system of the tractor vehicle and not by the main braking valve. The invention may also be applied to rail vehicles with trailers, for example, motor rail cars.
