Title: Improvements in or relating to pressure reaction vessels
IPC: C10G1/06
Filed: 1954-04-14
Abstract: <PICT:0760511/III/1> <PICT:0760511/III/2> A pressure reaction vessel is provided with an agitator comprising an electric motor 25 within a housing 32 and a rotatable shaft 20 provided with blades 19, the motor being positioned entirely within the pressure vessel and being immersed in a body of cooling fluid 28 within the housing, and the housing being discontinuous at the top so that the pressure on the cooling fluid is equalized with that in the pressure vessel.  The cooling fluid, e.g. oil, is introduced through pipe 30 into an enclosure 29, flows via bearings 31 into housing 32, and leaves at 33.  The housing 32 rotates with the shaft 20.  Openings 38 lead from the housing 32 into a jacket 35 which is in communication with the reaction section 17 of the pressure vessel.  A liquid seal 40 is provided at the bottom of the jacket 35 to prevent gaseous reactants coming into contact with the cooling fluid; the pressure in the jacket 35 may be maintained slightly above that in the reaction section of the vessel by supplying gas through pipe 44.  A splash shield 39 is arranged on the shaft 20.  Reactants enter the reaction vessel at 18 and circulate through a central tube 21, product leaving through pipe 22 and outlet 23.  The reaction section of the vessel is provided with insulation 15 and corrosion resistant lining 16. Reference is made to the reaction of a mixture of coal and oil with hydrogen in the presence of a catalyst at a temperature above 400 DEG C. and a pressure above 3,000 lbs. per sq. in. to form a product containing aromatic and volatile hydrocarbons, nitrogen derivatives of aromatic hydrocarbons, and nitrogenous heterocyclic compounds.

Filed: 1930-04-09
Abstract: 346,569. Cutting glass. SOC. INDUSTRIELLE D'ARTICLES DE BIMBELOTERIE, 4, Passage Rene, Paris.- (Assignees of Soc. Cadmail; 4, Passage Rene, Paris.) April 9, 1930, No. 11341. Convention date, April 9, 1929. [Class 56.] A machine for cutting-out shapes from sheet glass comprises a member which can be rotated about a vertical axis and moved radially by a fixed cam or templet, a diamond or wheel cutter supported by the member, and an arm which engages a second fixed cam and keeps the cutter facing in the direction of the cut. The device comprises a frame 1, Fig. 1, in which a vertical shaft 2 is journalled, a counterweighted lever 4 for keeping the shaft raised when out of use, and a handle 3 for rotating the shaft and for forcing it downwards when a cut is to be made. A slotted arm 12 is secured to and projects radially from the lower end of the shaft 2, and a member 9 slides in the slot in the arm and is forced inwards by a spring so that it is always in contact with a fixed cam or templet 10. The diamond 6 is held in a tube 7 which is free to turn within an arm 8 secured to the member 9. The tube 7 has a U-shaped arm 17, Fig. 2, and a roller 18 on this arm is kept in contact with a second fixed cam 11, by a spring. In use, a glass sheet is placed on the base 5 of the machine and the handle 3 is pressed downwards and rotated. The cutter is moved by the member 9 and scores on the glass an outline determined by the cam 10. The cam 11 turns the tube 7 on its axis and its contour is so chosen that the cutter always faces in the direction of the cut. If desired, the cams 10, 11 may be replaced by grooved plates thus dispensing with the springs required to keep the parts 9, 18 in contact with the cams.
Patent GB-349232-A (GB)
IPC: D01H13/30
Filed: 1930-04-10
Abstract: <PICT:0349232/IV/1> Artificial silk threads are unwound from bobbins or reels and passed from delivery rollers through a treatment bath, from which they are taken up and wound upon a spool rotated by means of a friction winding drum, the peripheral speed of which causes stretching of the threads.  Stretching of the threads may also take place in two stages, the first being effected by drawing rollers having a greater peripheral speed than the delivery rollers, and further stretching being applied by the peripheral speed of the friction drum and winding spool.  In some cases the stretching of the threads may be just sufficient to ensure levelling up of the whole length of thread to eliminate variations of natural elongation.  The treatment bath may be for any desired purpose such as moistening and softening the thread for subsequent stretching, or sizing.  As shown, artificial threads 2 are unwound from bobbins 1, passed from delivery rollers 4, 5 through a bath 8, removed from the bath, passed to swinging thread-guides 10 and thence to the nip of winding drums 12 which rotate, by friction, spools 13 on to which the threads are wound.  The peripheral speed of the drums 12 is greater than that of rollers 4, 5 and the threads are thus stretched.  In a modification, the threads are passed, immediately after leaving the bath, between a pair of drawing rollers to effect a first stretching of the threads which are still further stretched by the winding drums 12. The drums may be coated with soft rubber on a layer of vulcanite, the soft rubber exercising an efficient pull on the threads.  The spools may be cross-wound if desired.  The rollers 6, 7 in the bath 8 may be peripherally grooved, each groove receiving a thread.  A number of rows of wound spools may be mounted in the creel of a doubling frame and creping or other twisting may be effected.  The process is also applicable to already twisted or creped threads.
