Title: Improvements in or relating to continuous crystallization
IPC: B01D9/00
Filed: 1947-04-28
Abstract: <PICT:0629417/III/1> <PICT:0629417/III/2> Continuous fractional crystallization is carried on by feeding the solution into the middle one, or if desired, more than one of a series of containers 12, 18, 20 ... 28, Fig. 2, in each of which a cooled wall, preferably the surface of a drum 36 cooled by refrigerant fed to the inside, is brought into contact with the solution, scraping the crystalline deposit on each drum off into a heated hopper 64, flowing the melted crystals from each hopper into the adjoining container and so to the container 24 at one end of the apparatus, and flowing the mother liquors countercurrent to the melted crystals to container 28 at the other end.  The crystals from the last drum may be melted and so flow out of the apparatus into receiver 86, from which a portion may be fed back as reflux to the last container, or be removed from the unheated hopper by a conveyer belt-feeding into a receiver 104.  In an alternative apparatus, Fig. 6, the containers are rotating drums 112, the external walls of which are cooled by refrigerant passing through compartments 114.  The mother liquors pass from drum to drum through pipes 118, while the crystals deposited on the inner surfaces 119 are scraped off by scrapers 120 into heated hoppers 122 and thence through pipes 126 into adjoining containers in countercurrent to the flow of mother liquors.  The solution may be of a major component, e.g. benzene or naphthalene, with a small percentage of impurities, or of a eutectic or non-eutectic mixture.  Where the initial material is of high viscosity it may be thinned with a solvent such as methanol, ethanol or cyclohexane, and the solvent may be introduced into each container.

Abstract: 1369517 Television synchronizing circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 13 March 1972 [16 March 1971] 11612/72 Heading H3A A line time base synchronizing circuit comprises an arrangement, e.g. a phase discriminator, for comparing the frequency and phase of the received line synchronizing pulses with a reference signal derived from the line fly-back pulses 1 via a symmetrical limiter 3-8 provided for preventing shifts in the reference signal resulting from changes in an E.H.T. voltage derived from the circuit. The line fly-back pulses vary in amplitude and base-width depending on the E.H.T. load, but since all their waveforms pass through two points on a particular voltage level (Fig. 1, not shown) in the synchronized state of the circuit, a symmetrical limiter 3-8 is used to provide a pulse having a constant amplitude and a constant width about that voltage level which may be applied to a Miller integrator 9 for obtaining a reference sawtooth signal. The amplitude of the limited pulse may be varied by an adjustable resistor 3.

Filed: 1958-04-14
Abstract: 864,936. R.F. couplings. PYE Ltd. April 8, 1959 [April 14, 1958], No. 11782/58. Class 40(7) [Also in Groups XXXV and XXXVI] A high frequency transformer assembly capable of working over a wide band has the input and output connections of the transformer in the form of plate-like conducting surfaces. These are substantially non-inductive and are arranged so as to provide at least two capacities. It is explained with the aid of equivalent circuit diagrams (Figs. 1, 2 and 3; all not shown) how the satisfactory working bandwidth of a radio frequency transformer is reduced by the self inductance of the input and output connections, may be increased by using connections of low self inductance, and may also be increased by adding to the input and output capacities sufficiently to make the load appear resistive. In an embodiment of the invention intended to match a single incoming co-axial line to three outgoing lines a channel section metal plate 1 is provided with the input socket P1 on one of its flanges and the three output sockets S1, S2, S3, on the other. The transformer 6 is an auto-transformer and is enclosed in an iron dust pot mounted on a sheet of insulating material 5 bridging a suitable central aperture in the channel. The common point of the transformer windings and the outer sleeves of the co-axial connectors are connected to the channel 1. The inner conductor of P1 is connected to the primary winding via plate 2 mounted in the channel on insulators 4. The size of the plate 2 and its spacing from the channel are arranged to give the desired increase in input capacity. The secondary winding is connected to the inner conductors of the output sockets through a similar plate 3 making up the required output capacity and providing a substantially non-inductive connection. The channel member 1 may form part of a box enclosing the assembly. The construction may be modified so that the plates 2 and 3 are on opposite sides of the plate 1.

Abstract: 108,733. Ricardo, H. R. Aug. 22, 1916. Cycles aud systems of working; cylinders, construction. of.-Engines which inject a jet of liquid fuel into a charge of compressed air are provided with a small chamber E which is separated from the main combustion chamber B by a narrow passage F and into which is drawn during the first part of the suction stroke before the air valve C opens a charge of combustible mixture which is afterwards compressed and ignited by a sparking-plug K also situated in the chamber. The admission valve H has two faces and its casing G is constructed so as to be screwed forward until the valve bears upon a seating F' and cuts off communication between the chambers E and B. When used for starting, the combustible part of the charge is drawn exclusively through the valve H, and when the engine is hot the valve is closed against the seating F<1> and heavy oil is injected through the nozzle at B<1>. The apparatus may be used during normal running, the charge in the chamber E being ignited just before the end of the compression stroke and its expansion causing a turbulence of the air in the chamber B which aids the diffusion in it of the liquid fuel which is injected directly afterwards through the nozzle at B<1>.

Abstract: 350,651. Dressing fish. BISSET, J. D., Esplanade Sawmills, North Esplanade West, Aberdeen. April 16, 1930, No. 12004. [Class 28 (ii).] In a fish-skinning machine of the kind in which the fish is moved by a carrier, e.g. a rotary drum, into contact with the skinning knife, the carrier has sharp hooks, teeth or pins in a depression in its surface, so that the tail is impaled when it is inserted in the depression. A roller immediately behind the knife draws the skin from under the knife. As shown, the fish is rested, tail towards the drum 4, on a support 19, 20 which is reciprocated by a lever 21 actuated by a cam on the shaft 3 through the levers 24, 25. The part 19 is slidable relatively to the part 20 to which it is connected by a spring 27, so that when the support is moved towards the drum, the part 19 is first arrested by the drum whilst the movement of the part 20 continues, so that the tail is projected into the depression 10 into which the pins 11 are projected. The pins 11 are carried by a lever 12, 14 pivoted on a bracket 13 and are actuated by a cam 16 and a coil spring attached to the .arm 14. When the tail is positioned within the depression, it is forced on to the pins 11 by a presser 28 actuated by a cam on the shaft 3 through levers 30, 31. The knife 33 is a rigid blade adjustably mounted parallel to the drum axis, and is reciprocated by a crank and connecting-rod driven from the worm shaft 6. The drawing roller 38 is driven positively by a sprocket 39 and chain 40, the peripheral speed being greater than that of the drum. A pivoted scraper 43 is pressed resiliently against the drum by a rod 44 and a spring 47 which presses against the lever 21, and removes the skins from the drum.
