Patent GB-1603878-A (GB)
Title: Device for heating-up fluids
IPC: C02F1/14
Filed: 1978-05-03
Abstract: The device has a chamber (2) in which there is or are arranged for the fluid a skeleton-like material (1) or suspended, spatially distributed, fine particles. Furthermore, an artificial radiation source (4, 5) whose radiation heats the skeleton-like material is arranged inside or outside the chamber. Due to this arrangement, transport of heat by conduction to the surfaces around which flow takes place is no longer required and an additional heat transfer resistance is eliminated. Due to the large surface of the spatial structure or the suspended particles, convective heat transfer to the fluid takes place at small temperature differences. The device can be integrated into a recuperative heat exchanger. In order to achieve chemical reactions, the spatial structure which absorbs the radiation can have a surface refined by heat treatment and/or a catalytic effect. <IMAGE>

Filed: 1929-06-10
Abstract: 313,405. British Celanese, Ltd., (Assignees of Scheidegger, J., and Dreyfus, C.). June 9, 1928, [Convention date]. Halogenphenyl and homologous phosphates.- Brompbenyl and homologous phosphates may be prepared by direct bromination, nuclear substition occurring at a low reaction temperature and sidechain (if a side chain is present) at a high reaction temperature. Thus, by brominating tricresyl phosphate at ordinary temperature a product may be obtained having one bromine atom in each nucleus, but if four atoms of bromine are introduced at 150‹ C., one of 'the cresyl radicals is substituted in the nucleus, another in the side chain, and the third in both the nucleus and the side chain. Tetrabromination at 180‹ C. gives a product having each side chain substituted and one monosubstituted nucleus. Brom- and other halogen-phenyl &c. phosphates may also be prepared directly from the corresponding halogenphenol and phosphorus oxychloride or oxybromide.

Title: Anode tube for ionic valves for high voltage static current converters
IPC: H01J17/04
Filed: 1943-11-01
Abstract: 586,574. Metalvapour converters. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Nov. 1, 1943, No. 18007. Convention date, Nov. 5, 1942. [Class 39 (i)] An anode tube 2 for an ionic valve contains control electrodes 5 serving to distribute the voltage drop during the blocking periods and these electrodes occupy at least 70 per cent. of the space between the lower surface of the anode and the face of the electrode 5 nearest the cathode. The distance between bodies of different potentials is thus rendered too small for substantial ionisation' by impact and the setting up of undesirable discharges. The diameter of the container tube 2 is also rendered large in comparison with the cross sectional area of the current path thus improving cooling. Instead of a separate tube 2 the anode space may be closed by glazing insulating rings between the control electrodes. The electrode connections may be lead through holes in tube 2 into contact with caps 15 glazed to the tube. Alternatively, if tube 2 is. made of porcelain this is sufficiently conducting at the temperature of operation for the control electrodes to be connected to layers on the inside of the tube and a voltage source to be connected to corresponding layers on the exterior. Specification 586,588 is referred to.

Title: Justifying typewriters
IPC: B41J19/64
Filed: 1952-07-22
Abstract: 717,947. Typewriters. LEGLlSE, P. July 22, 1952 [Aug. 3, 1951], No. 18469/52. Class 100(4). In end-of-line justifying typewriters similar to those described in Specification 715,115, wherein the advance of the carriage displaces, e.g., a justifying lever L having thereon an adjustable device engaging and advancing the platen carriage a different extent, the adjustable device coacts with scales corresponding to different possible lengths of a normal terminal segment. The justification mechanism of the typewriter becomes operative at the commencement of the selected terminal segment so that the required letters to be typed in the terminal segment are expanded or contracted accordingly. At the commencement of the terminal segment a stop k on the machine frame engage the justifying lever L mounted on a carriage rack Cr and pivots it about the point O as the carriage rack Cr moves to the left under pull of the usual spring band W. The movement of the platen carriage Ch itself being equal thereto, greater, or less, according to whether a sliding stop A, pivoted on the lever L is, respectively coincident with, below, or above (as shown in Fig. 4) the point O. As occurs in the usual escapement mechanisms, letter-spacing takes place after printing so that the last spacing has no effect on the justification. This is taken account of in the embodiments shown, e.g. in one of these justification is effected in terminal segments of 28 or 55 normal letterspaces, chosen so that the expansion or contraction in the latter is exactly half that of the former. This facilitates the positioning of the sliding stop A into two series of notches +4, 0, - 4, and +IV, O, - IV, formed in a scale R, Fig. 8, and which correspond to the numbers of characters more than or less than those required for terminal segments of 28 or 55 letter-spaces. The scale R is detachably secured alongside the slot F accommodating the stop A. The notches of each series may. be formed of distinctive shapes and the marking formed in different colours. Scales accommodating other terminal lengths may be interchanged. As shown in Fig. 9, notches appertaining to 28-letter terminal segment are accessible but if this scale is reversed as shown in Fig. 10 a cut-out e exposes notches for a 55-letter terminal segment designated by markings on the, now facing, rear side of the top scale. In a further modification accommodating four different length terminal segments the notches are formed on the four sides of a square rod which can be clipped into required position. The sliding stop A may also be positioned by a pivoted spring lever, Fig. 12 (not shown), engaging in either of two series of holes formed in the slide frame. To reduce the space, required for the typewriter when the justifier mechanism is not in use the lever L may be made to fold or telescope; the stop k may be detachable from the typewriter frame.

Title: Improvements in cartridge feed mechanism for machine guns or other automatic firearms
IPC: F41A9/16
Filed: 1937-07-02
Abstract: 497,978. Machine guns. GEBAUER, F., and DANUVIA IPARI ES KERESKEDELMI R. T. July 2, 1937, No. 18493. [Class 92 (ii)] A cartridge-extractor for a machine gun is actuated through a motion-reducing lever system by a movable part of the breech-block mechanism. The breech-block 6, Fig. 1, may be linked at 7 to a lever 8 which is pivoted at 18 in the casing of the gun, the cartridgeextractor 10 being coupled to the lever 8 at 9 so that the speed of the extractor is less than that of the breech-block. The extractor has a claw 11 engaging over the rim of the cartridge 1, and pins 28 which enter guides in a carrier 13 pivoted in the gun at 12, the carrier being adapted to receive the cartridge on rearward movement of the breech-block. A pawl 15 pivoted at 14 in the carrier 13 is influenced by a spring 17 so that when the cartridge is freed from the belt or magazine 3, and has entered the carrier, the latter is swung downwardly about its pivot 12, until a lug 38 on the carrier engages a fixed abutment 37, this downward movement of the carrier being positively controlled by a cam 43 on a slide 23 which engages a surface 39 on the carrier. At the commencement of the forward movement of the breech-block, which is effected through the lever 8 by the spring 25, a lug 30 on the extractor slides the cartridge forward so as to enter its nose in the chamber 5 of the barrel, and at a given point in this movement the cartridge moves clear of restraint by the carrier 13 and, under the influence of the pawl 15, Fig. 3, takes up a position in front of the breech-block 6 which thereupon thrusts the cartridge into the chamber. As this action proceeds, a lug 26 on the slide 23 engages a cam surface 27 on the carrier and elevates the latter so that the extractor is correctly positioned to advance into gripping engagement with the fresh cartridge which has been aligned therewith. The feed of the cartridge belt or magazine is effected by a slider 36 driven by a bell crank 34, Fig. 4, coupled by a link 33 to the slide 23, the latter being reciprocated by the lever 8, through the link 22.
