Title: Improvements in self-discharging receptacles
IPC: B61D9/02
Filed: 1923-01-19
Abstract: 194,668. Krupp Akt.-Ges., F. March 7, 1922, [Convention date]. Addition to 164,703. Hopper wagons. - In a self-discharging receptacle of the type described in the parent Specification the gear comprising the toggle links E, F, Fig. 1, for locking the side flaps or doors B in the closed and open positions is adapted to be released either by manual operation of the link E or by means of a driving element in the form of a pinion H actuated by compressed air, the pinion H being rotatable on the shaft K carrying the arms C. C<1> and having two stops h<1>, h<2> which co-operate respectively with a projection f<1> on the link F and with a projection e<4> on the link E for the purpose of breaking the toggle in the closed and open positions of the flaps B. The link F is pivoted on the arm C and is provided with a slot f<3> in which a pin e<2> on the link E slides, and, in the normal or loading position, Fig. 2, the toggle is maintained by a spring G with a stop e<3> on the link E bearing against the link F. In effecting a discharge of the load by means of compressed air admitted to a cylinder M, a rack N rotates the pinion H and the stop h<1> on engaging the projection f<1> breaks the toggle, after which the weight of the load causes the further rotation of the arms C, C<1> in advance of the movement of the pinion H pn the shaft K. At the completion of the discharge movements of the pinion H and arms C, C', Fig. 4, a stop h<3> on the pinion overtakes a stop c<2> on the arm C and prevents the flaps B returning to the normal position under their own weight, while the stop h2 will have passed beyond or to the left of the projection e<4>. In the return movement of the flaps from the position of Fig. 4, the stop h<2> and projection e<4> break the toggle, after which the weight of the flaps returns the arms C, C<1> and, by virtue of the engagement of the stops h<3>, c<2>, also the pinion H and rack N to their initial positions. In the manual operation of the flaps B the toggle is broken in either position by a pull-rod connected to the link E, the pinion H with its stops h<1>, h<2>, h<3> remains stationary, and the stop, c<2> rotates with the arms C, C<1 >away from the stop h<3>. After reaching their extreme discharge position, the flaps B return under their own weight to a position, Fig. 7, determined by the length of the slot f<3> so as to establish a toggle E, F, as shown, with the spring G acting as the holding agent. Unlocking from this position to allow the flaps B to close is effected by operating the pull-rod connected to the link E.

Title: Urea synthesis process
IPC: C01C1/12
Filed: 1967-01-12
Abstract: 1,134,849. Synthesis of urea. CHEMICAL CONSTRUCTION CORP. 12 Jan., 1967 [20 Jan., 1966], No. 1791/67. Heading C2C. A urea synthesis process comprises recovering ammonia and carbon dioxide from the product stream by reducing the pressure adiabatically and removing an initial off-gas, heating the product stream to generate a first off-gas, absorbing at least some of the first off-gas in an aqueous medium, lowering the pressure of the residual product stream and passing the product stream in heat exchange with the absorption product of the first off-gas to heat the product stream and generate a second offgas. The process is suitably operated continuously and the initial off-gas may be combined with the mixture of first off-gas and absorbing medium (suitably an ammonium carbonate solution) discharged from the heat-exchange for recycle to urea synthesis. The pressure of the product stream after removal of the first off-gas may be reduced adiabatically, a partial off-gas separated prior to heating to form the second off-gas and said partial off-gas combined with the second off-gas. An apparatus suitable for carrying out the reaction continuously is described.

Inventor: PATERSON JOHN VINCENT
IPC: B27H5/02
Filed: 1956-01-20
Abstract: 797,026. Laminates. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Jan. 11, 1957 [Jan. 20, 1956], No. 1974/56. Class 140. [Also in Groups XXIII and XXVIII] Curved balsa wood members, particularly for forming a heat-insulating lining of a tank (see Group XXVIII), comprise two layers 1, 2 rigidly bonded to each other with the grain running in mutually perpendicular directions and then bent so that the axis of curvature is parallel to the grain of the layer 2 on the inner side of the curved member. A synthetic resin or rubber-based adhesive may be used for bonding the two layers provided it does not allow slip on bending. The two layers are made up of several strips 1a, 2a and the strips should preferably run the whole length of the layer but joins may be permitted in the layer 2 destined to be the inner layer, provided they do not occur opposite a join in the outer layer 1. The two layers need not be of the same thickness. For making thicker curved members, several flat two-layer members are assembled with liquid adhesive, preferably a resorcinol resin, between their surfaces and with the grain running in mutually perpendicular directions in adjacent layers throughout the assembly. The assembly is then bent with the grain of the innermost layer parallel to the axis of curvature, the members being allowed to slip over each other, and the adhesive is cured by high-frequency heating. An aluminium layer may be glued to one face of the member by a rubber-based adhesive.

Abstract: 437,342. Valve circuits for wireless reception. STANDARD TELEPHONES & CABLES, Ltd., Connaught House, Aldwych, London.-(Assignees of Ports, E. G. ; 12, Irving Avenue, Livingston, New Jersey, U.S.A.) Jan. 20, 1934, No. 2049. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 21, 1934]. [Class 40 (v)] In a radio receiver the received signal is rectified and the resulting D.C. voltage used to control the gain of amplifiers preceding and following the point from which the energy to be rectified is derived. In one example, a superheterodyne receiver comprises a first detector 6, Fig. 1, intermediate frequency amplifiers 14, 15 and second detector 16, an auxiliary intermediate frequency amplifier 18 being connected between valves 14 and 15 and feeding a rectifier 19. The D.C. output from the rectifier 19 is developed in a resistance 20 connected in the grid circuit of valve 6 whose gain is thereby controlled and a lead 24 tapped on to the resistance 20 is connected in the grid circuit of valve 15 to control the gain of the latter. In a modification, two auxiliary amplifiers and rectifiers are fed from a point between two first intermediate frequency amplifiers in a triple-detector receiver and control respectively the gain of the first and second detectors, Fig. 2 (not shown). In a third embodiment, the second detector 135, Fig. 3, of a superheterodyne receiver is a diode having a load resistance 156, 157, the D.C. potential across which controls the gain of radio frequency amplifier 130, first detector 131, and intermediate frequency amplifiers 132, 133, 134 through a resistance 164, lead 165 and filters 166 ... 170 respectively. The gain of the low frequency amplifier 136 is also controlled by including the resistance 156 in its grid circuit the potential across which is fed to the grid through a filter 172, 162. Manual volume control is effected by varying the bias on valves 130 and 132 by connecting their cathodes to a variable tapping 171 on a potential divider 143 ... 145 connected across the H.T. source 139.

Title: Improvements in or relating to recording and reproducing colour television
IPC: H04N11/00
Filed: 1954-01-25
Abstract: 748,201. Television. TECHNICOLOR MOTION PICTURE CORPORATION. Jan. 25, 1954 [March 31, 1953], No. 2165/54. Class 40 (3). In an arrangement for generating colour television signals by scanning a record (e.g. kinemotographic film) having a plurality of colour aspects and the picture elements of each aspect arranged in a predetermined pattern (e.g. the pattern of like colour dots or lines in a three colour R.G.B., dot or line picture) the scanning beam transmitted through the record is split into a like plurality of beams, each of which is directed on to a separate photo-electric cell through an individual apertured mark, the apertures in which correspond to the different pattern arrangement of the picture elements of each colour aspect. The record is made by photographing on a continuously or intermittently moving monochrome film the picture produced by a picture tube to which colour television signals are supplied, having a screen S (Fig. 6), comprised of a plurality of fluorescent elements, eb; eg; er; arranged in a pattern in which the elements representing one colour aspect are spaced from those representing another colour aspect the elements fluorescing in different colours or in the same colour. The masks Mb; Mg; Mr (Fig. 6), are likewise produced by photographing the tube screen which for this purpose is scanned by an unmodulated electron beam blue, green and red, colour filters being interposed in the optical'path during the production of the respective marks (which comprise positive prints of the negatives produced by photographing the screen) when the screen elements fluoresce in different colours or, alternatively, the scanning beam may be arranged to excite only those elements which correspond to the mask being made. Instead of a dot pattern the screen S may have fluorescent elements arranged in parallel horizontal or vertical stripes, the marks being made to have a corresponding pattern. The film so produced is then scanned by a "flying-spot" scanner the light transmitted through the film being split into three beams, each of which is directed through a respective one of the marks on to a photo-electric cell individual to the colour aspect determined by the mark and the red, green and blue colour aspect signals transmitted in known manner (Fig. 2, not shown). An advantage of the invention is that colour television pixtures may be recorded for retransmission without intermediate processes involving lengthy colour film development techniques.

Abstract: 548,797. Synthetic resin articles ; moulding plastic substances. CELLOMOLD, Ltd., and DAVIES, D. N. Feb. 19, 1941, No. 2251. [Class 2 (iii)] [Also in Group V] Articles, e.g. artificial limbs, helmets, dolls &c. are produced by applying to a former an acid hardenable resin, a hardener for the resin and a textile, paper or other highly flexible sheet material readily shaped to the former without the use of high pressure, the combined material being stiff enough to retain its shape whilst hardening of the resin occurs, whereafter the former is removed. In a modification, a former of skeleton wood or metal structure is employed and is retained as part of the finished article, e.g. an aircraft wing or fuselage. Hardening of the resin may be expedited by heating to 20-100‹C. Specified flexible materials are calico, flannel, cotton duck, hessian, muslin and paper; wood plies are excluded. The material may be in the form of a strip, e.g. a roller bandage or shaped pieces cut from sheet may be applied to the former. The resin may be admixed with the hardener and applied to the sheet material before, during or after application to the former, e.g. by-brushing, spraying or dipping. Thick sections may be formed of inner and outer layers of sheet material filled by a mixture of resin and scraps of sheet material or other fillers. Light pressure, e.g. less than 50 lb. per sq. inch, may be applied. Acid hardenable resins specified are phenol-formaldehyde and amino resins ; a suitable resin is produced by refluxing equal weights of phenol and 40 per cent. formaldehyde in the presence of an alkaline catalyst, e.g. sodium hydroxide. The acid hardener is admixed with the resin just prior to use ; hydrochloric, sulphuric, oxalic and benzene sulphonic acids are specified, the amount being about 7¢ per cent. of the resin.
