Patent GB-1072377-A (GB)
Title: Method and apparatus for bundling compressible sheets such as cardboard
IPC: B65B27/08
Filed: 1965-04-02
Abstract: 1,072,377. Wrapping-machines. SUNDS VERKSTADER A.B. April 2, 1965 [April 21, 1964], No. 14089/65. Heading B8C. A stack 71, Fig. 1, of compressible sheets, e.g. cardboard blanks, is bundled by pushing it into a paper tape 18 held normal to its direction of motion, so that the tape is wrapped round three sides of the stack, which is compressed during this operation. The tape is then separated from a roll 17 and its two ends glued together at the trailing end of the stack. In the embodiment the tape 18, drawn from a roll 17, after passing an idler roll 26 engages an edge folder 27 which folds the edges of the tape inwardly to provide reinforcement. The tape is creased along these fold lines in passing between the rollers 64 and 65 and is then fed between jaws (61, 62), Fig. 4 (not shown), of a releasable gripping device. At the inlet end of the conveyer 31 the bundle is straightened on all four sides by a series of rods (44) and 46, Fig. 2 (not shown), on the two sides, a gate mechanism 54 at the forward end and pusher bars 56 and 57 at the trailing end. It then advances into the wrapping station where its motion against the tape 18 causes the tape to be wrapped round the three sides of the stack. In this position the bundle 71 is compressed by means of a compression unit 72, manually adjustable by a wheel 73 to allow for different sizes of bundles. A laterally movable knife blade (82), Fig. 3 (not shown), carried on carriage (81) cuts the tape after the carriage 81 has moved down into the position of Fig. 3 (not shown). At the same time the jaws (61) and (62) release the other end of the tape upon which adhesive is then applied by a roller (84) in contact with an adhesive fountain (89). This roller then moves upwards and presses the end portion of the tape against the trailing end of the bundle 71. The other end of the tape is then lapped over the adhesived end, a roller (91) applying pressure to the seam. With the reciprocating carriage (81) in this position the jaws (61) and (62) are opened and a further supply of tape 18 is fed into them to provide for the next cycle of operation. With the closing of the jaws upon the tape, the wrapped bundle is sent to a second station still under compression where it stays until a second bundle is wrapped and sealed in the same manner. A cycle start button (122), Fig. 5 (not shown), is actuated by placing a bundle of material on the inlet of the conveyer. The conveyer is actuated as the gate mechanism 54 is retracted between the conveyer belts. The feeding of the tape end to the jaws (61, 62) energizes an electric eye (155) which stops the feeding of the paper strip into the jaws and moves the reciprocating carriage 81 upwards. The machine is then ready for another cycle of operation.

Abstract: 982,136. Amplitude modulation systems. MARCONI CO. Ltd. March 15, 1963 [April 12, 1962], No. 14173/62. Drawings to Specification. Heading H3R. Carrier is applied to one port of a four-port 3db directional coupler forming a quadrature phase equal amplitude phase splitter, with two other ports at opposite ends shunted by energy absorbing and matching impedances including resistance, capacitance, inductance and diodes so biased that normally there is no power output at a fourth port, but modulation applied to the diodes by varying their impedance produces mismatches and reflection of energy so that energy is proportionately supplied to the output port, while being of opposite phases and producing no reaction at the input port, so that this remains matched to the carrier source. The coupler system is suitable for wideband television video modulation. As only low stray capacitance may shunt the diodes the modulation power required is small. Chokes and/or quarter wavelength stubs may isolate the carrier from the modulation source. The diode bias may be zero or other value. The coupler may be connected to tappings on the inductor of the matching impedances, and the inductor or shunt capacitor may be adjustable for tuning the circuits.

Abstract: 143,507. Soc. Industrielle des TÚlÚ- phones. May 22, 1919, [Convention date]. Loading circuits to improve transmission.-A loading-coil for phantom telephone circuit is so arranged that the magnetic fields due to the two separate circuits and the combined circuit are mutually at right-angles. The core consists of laminated disks q with axial holes through which passes a bundle of iron wires r. Slots s, t, u, v are displaced 90 degrees from one another. One turn of the winding connected in one lead a is shown, and consists of two vertical parts in diametrically opposite slots s, u and two horizontal semicircular parts, one at the top and one at tha bottom of the core, forming between them a complete horizontal turn. Four such windings are arranged on the core displaced from one another by 90 degrees. Two diametrically opposite windings are connected in the two leads of one circuit so that the vertical magnetic effects of the currents in the horizontal planes cancel one another. The result is that of a vertical coif producing an horizontal field. The other two windings are similarly connected to the leads of the other circuit, producing an horizontal field at right-angles to the first. The currents in the combined circuit oppose one another in the vertical groovee, producing a vertical magnetic field. The magnetic circuit of this field is closed by bending over the iron wires r.

Title: Improvements relating to Calculators.
Inventor: GLASER WILLIAM HENRY
IPC: G06G1/04
Filed: 1916-10-10
Abstract: 109,330. Glaser, W. H. Oct. 10, 1916. Slide-rules having the graduations in certain parts of the scale so close as to introduce difficulty in reading are provided with means functioning as verniers whereby accurate reading is facilitated. The device is described as applicable to the solution of triangles for use in gunnery, and is provided with distance and log-sine scales. In the form shown in Figs. 1 to 3, the apparatus comprises a card bearing circular logarithmic scales a, b the first of which is graduated in sines from 1‹ 40<1> upwards, and the second in distances up to 8000 yards, the lower part of the distance scale being offset at e. The part of the scale a lying between 70‹ and 90‹ being too small for accurate reading, an enlarged scale c, Fig. 1, is formed, according to one method, by adding to each graduation a constant amount and providing a sector L, Fig. 2, bearing a scale h evenly divided with these markings, and a reading-mark f situated so that, when the mark f coincides with 70‹ on the normal log-sine scale a, the 70‹ on the vernier scale h coincides with 70‹ on the extended log-sine scale c. A second scale d, co-operating with a sector R bearing a second scale k and a reading- mark g, is provided. The reading-mark f extends inwardly far enough to read against the extension e of the distance scale, and the mark g reads only against the normal scales a, b. The sectors R, L are made of celluloid and pivoted at the centre of the scales a, b on members m, n, Fig. 3, clamped together by a screw o, the sector R being carried on a boss q which is smaller than a boss p carrying the sector L. A pin s passes through the parts m, n, R, and spring-washers t are provided so that the sector L is capable of adjustment independently of the sector R, but so that both move together when the sector R is turned. To avoid errors due to parallax, the scales are placed on the lower sides of the sectors, and the sine scales are graduated in angles and their complements. More particularly, the device is applied to the solution of triangles based on the formula x/Sin X = y/Sin Y = z/Sin Z The inner part of the disk bearing the distance scale may be made to revolve, and only one sector may be provided. In a modification, the scales may be marked on steel tapes and wound on drums placed side by side, means for locking the scales together when necessary being provided. The invention may be applied to scales other than those described, and a constant amount may be deducted from the scales instead of being added thereto.

Abstract: 1354076 Aromatic hydrocarbons METALLGESELLSCHAFT AG 28 March 1972 [3 April 1971] 14556/72 Heading C5E A mixture of aromatic and non-aromatic hydrocarbons is distilled to separate a fraction enriched in the aromatic compound (or mixture of isomers thereof ) which is present in the largest amount in the mixture, and from which this pure compound is recovered by solvent extraction or extractive distillation, and an overhead or bottoms material or a mixture of both overhead and bottoms materials is catalytically hydrodealkylated to produce a material from which benzene is recovered by distillation. Coke-oven benzene boiling between 70 and 150‹ C. and purified by hydrorefining is distilled to provide a benzene-rich overhead, which is subjected to extractive distillation to produce pure benzene, and a bottoms fraction, comprising toluene, xylenes and a small amount of benzene, which is passed to a dealkylation stage and the dealkylate product is distilled to produce pure benzene. A stream of pyrolytic gasoline is distilled to remove volatile non-aromatics and the residue is separated in a second column to provide an overhead rich in benzene which is hydrogenated prior to purification by extractive distillation and a bottoms which is hydrodealkylated to produce benzene which is recovered by distillation. A hydroformate is distilled at F1 to remove a volatile non-aromatic stream 2, a side stream 1 containing benzene and toluene, and a bottoms stream 3, which is distilled at F2 to provide a xylene fraction 4 which is purified by extractive distillation. The bottoms 5 are combined with the benzenetoluene stream 1 and hydrodealkylated to produce a benzene-containing stream which is then distilled to provide a stream 10 of pure benzene. The hydrodealkylation can be carried out at 500-800‹ C. and 30 to 80 atmospheres using a catalyst such as nickel, nickel oxide, or cobalt oxide + molybdenum oxide on alumina.
