IPC: D01D5/247
Filed: 1935-02-13
Abstract: A filter filling for cigarettes, cigars, and tobacco pipes and having longitudinally extending passageways or cavities therein is formed by extruding through an orifice a solution of cellulose derivative in a suitable solvent (preferably together with fibrous material such as finely divided cotton or wood pulp) and also passing through said orifice streams of coagulating fluid from a plurality of jets and then coagulating the cellulose derivative. Viscose may be used for the filter filling and coagulation effected in an aqueous solution of sulphuric acid and sodium sulphate, the rod being allowed if desired to remain in the coagulating bath for some time for completion of the coagulation to be effected, or a solution of cellulose acetate and/or formate in acetone may be employed with water or other suitable coagulant. Inert fillers such as calcium carbonate and kieselguhr, or plasticizers such as tricresyl phosphate or triacetin may be added to the compositions.  The extrusion device is preferably of such aperture that the coagulated rod needs only to be cut to the desired lengths.ALSO:A filter filling for cigarettes, cigars, and tobacco pipes and having longitudinal passageways or cavities therein is formed by extruding through an orifice a solution of cellulose derivative in a suitable solvent (preferably together with fibrous material such as finely divided cotton or wood pulp) and also passing through said orifice streams of coagulating fluid from a plurality of jets and then coagulating the cellulose derivative.

Title: Digital relay systems
IPC: H04B17/00
Filed: 1976-02-06
Abstract: A delay arrangement (39), an error detector (40) and a control logic circuit (43) are provided to switch one of the operating channels (16-20) over to the reserve channel (28) or vice versa. With the aid of the aforementioned devices, a synchronous relationship is established between the phase of the data signals which pass through the reserve channel (28) and the phase of the data signals which pass through the operating channel which is to be replaced. Furthermore, a changeover switch (34, 35, 36, 37, 38) is in each case assigned to each operating channel (16-20). The control inputs of the changeover switches are connected to outputs (44-48) of the control logic circuit (43) for switching the relevant operating channel over to the reserve channel (28). The changeover is enabled when the error detector (40) identifies precise synchronisation between the aforementioned data signals. In this way, data transmission is not impaired during channel changeover; no data can be lost. <IMAGE>

Title: Improved reflux condensers
IPC: B01D1/08
Filed: 1956-02-21
Abstract: A reflux condenser, which may be used for the separation of ethylene from coke oven gas by fractional condensation, comprises a cylindrical casing 8, a bundle of vertical tubes 9 with connections for passing cooling fluid through the tubes, and rectifying trays 6a, 6b extending across the casing, the tubes passing through holes in the trays and the arrangement being such that the rising gas passes through the annular gaps between the tubes and the edges of the holes, and bubbles through the liquid on the trays.  The gas flowing upwards around the tubes is partially condensed; and the resulting <PICT:0801493/III/1> liquid streams down on the tubes and accumulates on the trays. The liquid is hindered by the pressure of the gas from flowing down through the annular gaps.  The liquid flows inwards on trays 6a, then weirs over into central tube 10 and is delivered on to trays 6b.  On trays 6b the liquid flows outwards, then flows down in the gap between the casing and a cylindrical jacket 11, and is delivered on to trays 6a.  Round baffles 7a and annular baffles 7b are mounted between the trays.  By using an appropriate number of trays, there can be collected, in the upper part of the condenser, a liquid which is in equilibrium with the incoming gas; while the gas stripped of its heavy components is obtained at the upper part of the condenser.

Filed: 1968-02-02
Abstract: 1,189,765. Typewriters. ING. C. OLIVETTI & C. S.p.A. 2 Feb., 1968 [6 Feb., 1967], No. 5525/68. Heading B6F. Single pawl escapment; back-spacing.-A back-spacing mechanism for half-spaces comprises a toothed rack 8 on the typewriter carriage normally engaged by a single escapement dog 9 and which is momentarily disengaged to permit letter-spacing, and a backspacing pawl 41 which is firstly pivotal to engage the rack and is then moved to the right, Fig. 1, to effect back-spacing; the pawl 41 having a lug 52 so that when, and only when, it is in the rightward position it can be released simultaneously with the disengagement of the escapement dog 9. The escapement dog 9 is actuated from a part revolution cam 21 clutched to a continuously rotating drive shaft 22 causing a follower lever 25 to pivot a lever 27 which firstly pivots a lever 32 having a lug 36 at the other end that engages a shoulder 37 to release the dog 9. Then the lever 27 engages a projection 30 of a hook 18 causing the release of a lever 11 upon upon which the dog 11 is mounted at 10. As the lever 11 rotates up to a stop 38 it causes the dog 9 to move to the right so it engages the next tooth of the rack 8. The rack 8 being urged to the left in a letter-space direction, effects a whole letter-space. The type-carriage is back-spaced by half a letter-space by the operation of a key 71 and a part revolution clutch 60 operates a follower lever 56, bell-crank 47 and a connecting rod 45. This causes a lever 43 to pivot on pin 44 whereby the pawl 41 firstly engages the rack and then moves it a half letter-space in the backward direction. If the key is released the carriage returns to the original position, but if the key 71 is held depressed and a type key operated, the rocking of the lever 27 turns a shaft 28 which has a lever 53 which engages the lug 52 on the pawl 41 which is thereby released.

Abstract: 1,166,383. Production of aminonitriles. W. R. GRACE & CO. 6 Feb., 1967 [6 May, 1966], No. 5530/67. Heading C2C. Aminonitriles are obtained by reacting an amine having at least one replaceable hydrogen atom, formaldehyde, and hydrogen cyanide in the presence of an aqueous slurry of an acidic ion exchange resin. The hydrogen cyanide and formaldehyde reactants are preferably present in excess of the stoichiometric amount required and the reaction may be effected at 0-150‹ C. Hexamethylene tetramine may be employed as a source of ammonia (which may be the amine reactant) and formaldehyde. The ion exchange resin employed is preferably of the cationic synthetic organic resin type [e.g weakly acidic carboxylic (such as polymethacrylic) and strongly acid sulphonated polystyrene types] but other naturally occurring and man-made inorganic cation exchange materials may be used, several being specified. The amount of acidic ion exchange resin present may vary from about 0.1 to about 4 equivalents of acid substituents per equivalent of amine present. The aminonitriles obtained may be hydrolysed by conventional means (e.g. with sodium hydroxide) to yield the corresponding acid derivatives. Specific examples describe the preparation of nitrilotriacetonitrile and ethylenediamine tetraacetonitrile and the hydrolysis of the latter to ethylenediamine tetraacetic acid.

[Class 80 (ii).] In a motor vehicle having a tubular frame, the gear lever is pivotally mounted on one side of the frame, is curved around the frame and acts on selector bars arranged on the opposite side thereof. A bearing bracket b is secured to the frame tube a, and at its lower end b<1> carries a bolt d provided with a sleeve e ; the end c<1> of the gear lever c fits within the sleeve e and has a bore f which is larger than the bolt f ; the lever can thus be moved in all directions. The selector bars g, h, i are slidably mounted in the bracket b above the frame a. Notches g<1>, h<1>, il in the bars constitute the gate and are engaged by a ball c<2> on the lever ; simultaneous displacement of two selector bars is prevented by balls m<1>, m<2>. The notches h<1>, il are staggered so that the bar h must be moved before the bar i can be displaced ; by means of the latter bar an alternate clutch arrangement as described in Specification 390,638 can be actuated, which enables a noiseless change-over to be effected from the direct to the high speed and vice versa. A spring-loaded member k prevents inadvertent engagement of the fourth speed. A brake lever n is pivoted to the bracket b. A twoarmed gear lever may be used, in which case the lever is pivoted above the tube and the selector bars are arranged below the tube.
