Abstract: 649,220. Liquid level pressure gauges. DOBBIE McINNES, Ltd., and MORE, J. Oct. 21, 1948, No. 27428. [Class 106 (ii)] [Also in Group XXIX] A liquid depth or ship's draught or displacement gauge of the manometer kind described in Specification 627,864, is arranged to measure, e.g. the liquid depth in a tank 14 which may be either open or closed to atmosphere, in the latter case, the space above the liquid may be at a pressure other than atmospheric. The control valve of the gauge, comprising two interconnected diaphragms adapted to seat alternately, interconnects in one position passages 7 from a compressed air source, 6 from the sight-tube of the manometer, 5 from the bottom of the tank and 4 from the manometer reservoir, and in another position disconnects passages 6, 7 from passages 4, 5 and connects passage 6 to a passage 8 communicating with the space 8B above the liquid if the tank is closed, or with atmosphere at 8A if the tank is open. Passages 4, 5 are always interconnected. It is stated that where the manometer is placed in a compartment subject to a pressure greater than atmospheric, the passage 8 is used to connect the sight-tube to a space at atmospheric pressure.

Title: Fuel quality testing device
IPC: G01N33/28
Filed: 1960-08-08
Abstract: 909,198. Detecting water in fuel. BENDIX CORPORATION. Aug. 8, 1960 [Aug. 10, 1959], No. 27440/60. Class 97 (3). [Also in Group I] A water-sensitive element 24 for a fluid quality testing device comprises a first series of layers 32 of material, e.g. treated paper, cellulose, fibre, which is impervious to fluid and remains substantially inert upon contact with water, and a second series of layers 34 of watersensitive material, e.g. paper, cotton, which swells upon contact with water, alternate layers of each series being interleaved and having interstices therebetween (see Fig. 1A, not shown), which become substantially, or completely, blocked upon the swelling of the water-sensitive material. The element 24 may be formed of a ribbon of each material which is coiled, or be composed of washers of each material. A retainer Belleville spring 28 permits limited extension of the element in the presence of water, but only with reduction in the pore size. In a modification (Figs. 3, 4, not shown) with elements in parallel, a coil spring similarly permits extension of each element, but without reduction in the size of the interstices until the coils of the spring contact each other. In a further modification (Fig. 7, not shown), a demulsifier is in series with the combined watersensitive elements, and a pressure gauge, connected between the inlet and outlet of the device, indicates the presence of water, due to the rise in differential pressure upon swelling of the water-sensitive material.

IPC: B01D1/02
Filed: 1921-10-18
Abstract: 184,760. Caspar, C. H. Aug. 17, 1921, [Convention date]. Distilling plant; film evaporators.-In concentrating or distilling liquids such as fermented products, fruit juices, sugar solutions, &c., and in separating salt &c. from solutions, a gaseous medium is maintained in continuous circulation over the liquid and through a condenser. The liquid is supplied through an inlet 25 to the lower of the drums 1, 2, through which a gas such as air, carbon dioxide, &c. is circulated by fans 30, 30<1>. The lower drum 1 contains a rotary shaft 6 carrying connected coiled tubes 10 through which water or other liquid is drawn by a pump 13, and is passed through a cooler 15 through fixed coiled tubes in the upper drum 2, through a heater 20, and is returned by a pipe 22 to the coils 10 in the lower drum. The circulating gas from the coolest part of the condenser is thus brought into contact with the liquid in the coolest part of the evaporator. Atmospheric or higher pressures may be maintained in the apparatus. The upper drum may be divided by partitions 35 so as to collect different condensates. The directions of the gas and liquids may be reversed, the apparatus 18 being then used as a heater and apparatus 20 as a cooler. The volatile vapours given off by wines &c. may be used as a gaseous medium.

Filed: 1928-09-28
Abstract: 297,847. Marconi's Wireless Telegraph Co., Ltd., of Roberts, W. van B.). Sept. 29, 1927, [Convention date]. Vacuum tubes.-A valve with a filament heated by alternating current has means additional to the filament for producing within the valve a magnetic field compensating for variations in the anode current due to variations of potential on the filament. For this purpose a coil 15 'in series with the filament 13 may be mounted within or outside of the envelope, the adjustment' of the magnetic field due to the winding being effected by varying the distance of the winding-from the grid 12, anode 11 and filament, or by varying the number of turns. The filament has a low voltage drop across its ends and a high current carrying capacity so that it produces a substantial magnetic field assisting that due to the coil. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a valve in which' the coil is omitted and the resistance and dimensions of the filament are chosen to produce the desired compensation. For example, a V-shaped filament consisting of a rectangular core two inches long, and coated with oxide, may have a resistance of 1.5 ohms., and may operate at voltageswell below 1.5 volts. This subject-matter does not appear in the Specification as accepted.

As shown Figs. 1 and 2, a pair of rigid rods 11, 12 of NiFe alloy with Cu cores 16, 17 to improve their thermal conductivity are arranged a required distance apart and mounted by pinching a softened glass tube 41 round them to form a base 13 which also embeds terminal conductors 23A, 24A, 35A, 35B, 36A, 36B. A wire comprising a core of constantan coated with Cu or Ag is wound round the upper ends of the rods 11, 12, which are insulated by thin layers of glass (not shown), and the turns are secured by deposits 20, 21 of adhesive material. Selected portions of the coating of each turn are removed by etching to form a plurality of thermocouples and nichrome heating elements 35, 36 are secured by means of insulating adhesive to the lines of junctions on opposite sides of the coil to form a differential RMS converter. The coating is left on the wire where it passes round rod 12 but since the junctions 27, 28 are at the same temperature this does not contribute to the output of the device. The two sets of junctions may be thermally isolated by a plate 31 fitted into slots 32, 33 in the rods 11, 12 and the outer ends of the rods are connected to an external heat sink. A glass case 40 may be placed over the assembly and secured to the base and may be evacuated. The rods may be of different shapes, e.g. triangular or rectangular and three or more rods may be used. The heating elements may be omitted and the device arranged and utilized to detect incident radiation.

Abstract: 1,045,665. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. July 5, 1965 [July 7, 1964], No. 28376/65. Heading G6C. A fuel element comprising an outer can provided with longitudinal sets of parallel cooling fins is supported inside an annular metal jacket by a set of metal centring plates fixed to the jacket, e.g. by welding or bolting, and located along generating lines of its inner surface, each plate having at its lower end a flange engaging in a slot formed in a cylindrical end-piece on which the lower end of the element rests, the plates entering longitudinal grooves formed between the sets of fins on the fuel element can. Preferably, the fins are in herring-bone formation, the sectors of which are separated by longitudinal grooves. The jacket and supporting end-piece thus form a singleunit assembly constituting a " basket " in which the fuel element is axially engaged. The fixing of each centring plate to the jacket may be carried out solely in the upper part of the jacket or at points suitably distributed over the entire height of the plate. Each centring plate may comprise at its lower part an extension, enabling two successive jackets to be relatively centred when the jackets are superimposed end-to-end within a reactor duet.
