Title: Extractor for removing the contents from envelopes
IPC: B43M7/00
Filed: 1975-07-03
Abstract: 1506409 Removing contents from envelopes DOCUTRONIX Inc 3 July 1975 [13 Aug 1974] 28026/75 Heading B8C [Also in Division B4] An extractor for removing the contents from an envelope which is opened along one side, comprises transport means 28 which advances an envelope along a path to severing means 30 which engages each envelope and cuts it along a line spaced inwardly from each of two opposed edges to leave the envelope panels connected along only one edge. Separating means 34 engages and releasably holds one of the panels moving it away from the other and from the contents. The severing means 30 preferably cuts through only the lowermost panel and as described comprises a pair of cutter units each including a rotating cutter wheel and associated anvil wheel which together define a nip therebetween, the spacing of the wheels being variable by means which includes a biasing member for biasing the wheels together. Means are also preferably provided for directing the contents away from the severed envelope. As described, the means comprises a fixed deflecting plate 38 which is tangentially arranged to a separating drum which constitutes the separating means. Preferably, conveying means receives each severed envelope from the separating means 34, the conveying means defining first and second paths which terminate at different locations there being provided a coveyer gate 42 which is movable from a first one to a second position manually or by a signal initiated by sensing means 44, so as to cooperate with the conveyer means to divert an envelope along the first or second path respectively. The sensing means 44 senses the thickness of the envelope and, as described, comprises a plurality of spaced photo-electric devices which generate a signal in response to a simultaneous response from the devices. As described a first drive means drives the envelope transport means 28, the severing means 30 and the separating means 34, second drive means driving the conveyer means. A clutch operably connected to the first drive means and operable in response to operation of the gate moving means disables the first drive means to stop the separating means at a predetermined position.

Title: Improvements in or relating to the production of bulked continuous filament yarn
IPC: D01D5/06
Filed: 1959-08-19
Abstract: 902,642. Fnishing yarns. DU PONT DE NEMOURS & CO., E.I. Aug. 19, 1959 [Aug. 26, 1958], No. 28355/59. Class 120 (3). A bulky yarn comprises continuous filaments looped and entangled at intervals throughout the filament length to form bulky sections varying in random fashion in the yarn, the minimum variation in length being at least five-fold and the minimum variation in bulkiness being at least two-fold. Bulky yarn is produced by feeding a multifilament yarn or filament bundle of zero twist in a rapidlymoving co-current stream of liquid into a chamber in which a turbulent swirling motion is imparted to the liquid, and withdrawing the resulting bulky yarn from the chamber. The yarn may be formed by wet spinning, e.g. regenerated cellulose, acetate or polyacrylonitrile filaments, and feeding in a stream of coagulating liquid into the chamber. The filaments may be blended with synthetic polymer, e.g. polyamide, polyacrylonitrile, polyester, polyurethane, polyvinyl chloride or vinyl chloride copolymers, during passage through the liquid. In the operation of the apparatus shown, freshly formed filaments 4 from a spinneret 1 are fed into a coagulating and regenerating liquid 2 and filaments and liquid are forced through a conduit 5 by the pressure head of the liquid in spin box 3 and into a chamber 6. Turbulent swirling motion is obtained by jetting a second stream of coagulating liquid through conduit 14 into chamber 6 at an angle of about 90 degrees to conduit 5. The velocity of this stream passing through orifice 8 is such as to impart a swirling motion sufficient to deflect the filaments in a circular path, Fig. 3, around the chamber to an outlet 9 and into a tube 11 from which they pass through a bath 21 around guides 16, 17, 17a, 18, prior to winding under low tension. Specification 732,929 is referred to.

Abstract: 392,565. Excavators. EVANS, W. E., 27, Chancery Lane, London.-(Demag Akt.- Ges. ; Duisburg, Germany.) Oct. 14, 1931, No. 28594. [Class 68 (i).] In a scoop-arm or grab excavator with a two-speed drive for the hoisting means, the drive is transmitted through change-over clutch mechanism such that no interruption of the drive occurs during the changing of the speed. The traction drive may be effected by the same means. As shown, a Diesel engine 1 drives a shaft 3, which through clutch 4 or 5 controlled by a lever 15, drives fixed gear wheel 6 or loose gear wheel 7. One or other of the clutches 4, 5 is always engaged. The gear wheel 6 is fixed to a ratchet wheel 8a and drives the hoisting drum 11 at high speed through shaft 12, gearing 9 and a clutch 10 with hydraulic or like control means 18 controlled by a handle 17 on the lever 15. With the clutch 4 free and the clutch 5 engaged, the gear 7 is driven and drives the ratchet wheel through a ring 8b carrying pawls, the drum 11 then being driven at low speed. Reversing bevel gearing 13 driven from the shaft 12 operates traction mechanism and reversing bevel gearing 14 driven from the shaft 3 operates the turntable.

Title: Improvements in silencing devices for gaseous currents
IPC: F01N1/06
Filed: 1932-10-17
Abstract: 401,485. Silencing gaseous currents. PAVILLON, A. F., Mamie Cottage, Avenue Duval Lecamus, St-Cloud-les-Coteaux, Seineet-Oise, France. Oct. 17, 1932, No. 28954. Convention date, Oct. 22, 1931. [Class 7 (ii).] The stream of exhaust or induced gas to be silenced passes through a pipe 4, Fig. 1, into a damping chamber 1, the length of which is many, e.g. ten, times its diameter, the outer end 2 of the chamber being closed. A discharge pipe 6 is provided at the inner end of the chamber. The stream of gas, in order to reach the outlet, has to change its direction of flow abruptly, and, as a consequence, the pulsations are separated from the stream and travel forward into the chamber 1 wherein they are damped by friction and reflexion. To assist in the frictional damping, the chamber may be filled with such materials as steel turnings, shavings, wool or rags. Further, its walls may have projections, as shown in Figs. 7 and 10, and a core with projections may be inserted, as shown at 22, Figs. 17 and 18. Other forms of projections are described and shown, and the chamber may be surrounded by a casing, the space between the two being filled with vibration-deadening material, Fig. 13 (not shown). The damping chamber may comprise a number of sections placed end to end, each section having one of the different forms of internal projection described, Fig. 19 (not shown). In Fig. 3, two damping chambers 1, 1a, with closed ends 2, 2a, are employed, the inlet pipe being shown at 4 and the outlet at 6. In a modification the pipes 4, 6 are within the chambers 1, 1a. In Fig. 5 a triple arrangement is shown, the damping chambers 1, 1a, 1b communicating with chambers in which the change of direction occurs. In all forms, the inlet and outlet may be interchanged. Applications of the silencing device to motor-cars, steam locomotives and aeroplanes are described with reference to Figs. 20, 21, 22, and 23 (not shown). In the case of an aeroplane, the damping chambers may be formed in the fuselage side chambers or the wing boom, and, in the case of motor cycles, the frame tubes may form such chambers.
