Title: Method of regenerating particulate active carbon catalysts
IPC: B01J38/00
Filed: 1961-07-13
Abstract: The particles of an impregnated carbon catalyst which have had their outer shell eroded are regenerated by subjecting the particles to movement relatively to one another by the action of a stream of an activating gas and/or vapour followed by reimpregnation.  Activating gases or vapours are those containing free or combined oxygen, e.g. CO2, air, and steam.  The regeneration may be effected in a fluidized bed and may form an integral part of a reaction system wherein used catalyst is continuously removed, reactivated and refed to the reactor.

Title: Improvements in or relating to electric signalling systems
IPC: G08C19/16
Filed: 1939-09-11
Abstract: 534,694. Photo-electric signal transmitters. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Sept. 11, 1939, No. 25582. Convention date, Sept. 21, 1938. [Class 40 (iii)] [Also in Group XXXVIII] Cathode-ray tubes at the transmitter and receiver are caused to sweep out paths in synchronism by the application to the deflecting system of a synchronizing voltage, signalling being effected by obstructing a photo-electric pick-up cell at a variable point in the path, the impulse from the cell being transmitted to the receiving tube to cause illumination of the spot at the corresponding point in its path. The obstruction at the transmitter may be an instrument pointer, or a member indicating a message character. The received indications may be used for operating a relay or for gun-laying by followthe-pointer methods, or receiver indications from a director and a gun may be compared to derive a voltage for driving the gun into correspondence. In Fig. 1 (not shown), the spots describe circular paths by application to the deflecting system of synchronizing voltages in quadrature. By superimposing a higher frequency on the synchronizing frequency, the spot at the transmitter oscillates between two different radii and the "spot " at the receiver becomes a radial line. The paths of the spots may be elliptical, spiral or linear depending on the nature of the synchronizing voltage. The receiver may illuminate a scale or letters, figures &c. The pulses from the cell may cause a pulse of high frequency to be superimposed on the synchronizing voltage, or the synchronizing and signal voltages may be transmitted as modulations of the same or different carriers. A cathode-ray tube may send a number of different indications by scanning several pointers in succession during a single sweep of the beam. A modification of this arrangement is shown in Fig. 8 in which transformers TT and TR at the transmitter and receiver apply different synchronizing voltages in succession to the tubes so that the beams sweep out paths of correspondingly different radii, those at the transmitter being obstructed by different indicators. The transformers have tapped primaries supplied in succession by generator M over a commutator CR. In this and other arrangements, phase shifters C may be used to compensate for phase displacements occurring during transmission.

Filed: 1949-10-11
Abstract: 673,004. Paper &c. bags. FISCH, R. A. Oct. 11, 1949 [Jan. 27,1949], No. 26132/49. Class 94(ii). [Also in Group V]. A deformable closure member for a bag comprises a flat strip of flexible thermoplastic material having one or more linear members of deformable wire or metal stripcompletely embedded therein, the thermoplastic material being extended over the ends of the metal, member or members so that no parts of the latter are exposed. In an example a flexible strip is made by extruding thermoplastic material around three parallel wires which are fed longi-' tudinally through a die 20 of the form shown in Fig. 2 (see Group V), the orifice 30 of the die being of rectangular shape with a narrow extension 31 at one edge, the latter serving to form a flexible tab or tongue which is used to attach the strip along one side of the mouth of a bag of paper or plastic material. As shown in Fig. 3 the width of the tab 16 is made equal to that of a bag by cutting at 17 and 18, and the thermoplastic material at the laterally projecting portions of the strip 13 is extended around and beyond the ends of the wires 10, 12 by pressing the ends 14, 15 of the strip between a pair of heated dies of the appropriate shape. The tab 16 is adapted to be heat sealed to one side of the mouth of a bag made of similar thermo-plastic material, e.g. polyethylene film. Such a bag may serve as a liquid container, and closed by rolling the strip 9 several times over the mouth of the bag and bending the ends inwardly. In a modification, Fig. 7 (not shown), the tab 16 is omitted and the closure strip contains two parallel embedded wires spaced to allow a line of staples to be inserted to attach the strip to a paper bag. Fig. 10 shows a closure strip 9<SP>11</SP>, similar to that of Fig. 3 without the tab 16, and attached to a gusseted bag 50 which is provided with a rectangular rear flap or extension folded around the closure strip. The bag 50 may be made of thermoplastic material, which is unitable with the thermoplastic material of the closure strip, or it may be made of fibrous material such as paper or cloth. In an alternative method of making the deformable closure member, a V-shaped thermoplastic strip is extruded and the wire or wires subsequently embedded between the limbs of the V. Examples of natural thermoplastics that may be employed comprise natural rubber and guttapercha. Synthetic thermoplastics include: (1) The vinyl resins such as the polymers and interpolymers of vinyl chloride, vinyl acetate, etc.; (2) synthetic rubbers such as the copolymers of butadiene or isoprene with styrene, etc., (3) the acrylates such as polymethyl methacrylate, polyethyl methacrylate, etc., (4) polyethylene, (5) polyvinylidene chloride, (6) polyamides, particularly the flexible type such as those prepared from dicarboxylic acids and N, N<SP>1</SP>- diakyl diamines. Cellulose derivatives, which are enumerated in the Specification, may also be employed.
