Title: Sound-absorbing structures
IPC: G10K11/172
Filed: 1975-06-23
Abstract: 1490923 Sand insulation SHORT BROS & HARLAND Ltd 21 June 1976 [23 June 1975] 26606/75 Heading F2X [Also in Divisions B5 and F1] A sand absorbing structure comprises a porous facing sheet 20 and a non-porous backing sheet 21 with a core structure 22 connecting the facing and backing sheets and forming with the facing and backing sheets a plurality of side-byside resonating chambers, and intermediate porous members 25 each dividing an associated one of the chambers into two cells 23, 24, the intermediate porous members being so constructed and arranged that adjacent intermediate members or adjacent groups of intermediate members have differing porosities to cause adjacent associated chambers or groups of chambers to absorb sounds of differing ranges of frequencies. The porosity of the intermediate members may be constant in one direction parallel to the facing sheet but vary in a second direction parallel to the facing sheet but normal to the one direction. Facing and backing sheets 20 and 21 may be of metallic material. Intermediate porous member 25 may be a perforate sheet, the porosity being varied by variation of the size of the perforations and/or by variation of the number of perforations per unit area of the sheet. A porous sheet of woven or non- woven organic or inorganic fibres may overlie and be bonded or welded to facing sheet 20 or intermediate sheet 25. The facing and intermediate sheets may also be sheets of woven or non-woven organic or inorganic fibres with the fibres providing variable porosity. The porosity of facing sheet 20 whether of metal or fibres may be varied to accommodate variations in ambient conditions. The sound absorbing structure may be used to line at least one of the ducts of a gas turbine engine and may be of annular configuration. In alternative arrangements the backing sheet is conical and is inclined to the facing sheet and intermediate sheet so that the intermediate sheet divides the chamber in different proportions.

Abstract: 315,146. Herrmann, A. Sept. 17, 1928. Splints; supports for fractured limbs. - A first aid bandage for use in the case of arm and leg fractures consists of two equal layers of cloth a, sewn together at the edges, and containing a pocket e into which is slipped a bar f. The bar is so constructed that it can be extended to double its length, and it is retained in this position by means of a hook and an eyelet; the eyelet, fits into the buttonhole k in the pocket e and prevents the bar from slipping out. One layer of the cloth contains an aperture c through which further bars l, m of different lengths are inserted as required. The bandage and the bars are kept in position on the fractured limb by fixed straps n, o and loose straps q, Figs. 6 and 7 show two uses of the bandage. A wrapper for the bandage consists of a layer of waterproof material provided with binding straps and loops so that it may be used as an underlay, or, when provided with bars, as an additional bandage.
Patent GB-1469976-A (GB)
Title: Method for producing an electrical power contact
IPC: H01H11/04
Filed: 1974-06-15
Abstract: The process for preparing an electrical contact material for use in medium-size power switches comprises mixing silver powder with cadmium oxide powder or cadmium powder, whereupon the mixed powders are compacted at approximately 800 kp/cm<2>, and the compact is heated in a reducing atmosphere to obtain a porous alloy of cadmium in silver, without melting the compacted components. The reduced compact is then heated in an oxidising atmosphere in order to reoxidise or oxidise the cadmium in its interior without a melting process. Alternatively, other metals, for example copper instead of silver, can be used in this process. It is also possible to admix an oxide of a third metal, for example lithium or another alkali metal in powdered form. A fourth metal can be added to achieve other desired properties of the material. The contacts are stamped, or are punched from the composite material and treated by further metallurgical techniques such as sintering or rolling, in order to prepare the final contact material.

Abstract: 833,243. Testing presses. VYZKUMNY USTAV TVARECICH STROJU A TECHNOLOGIE TVARENI. S e pt. 3,1956 [Sept. 16, 1955], No. 26868/56. Class 87(2). [Also in Group XXIX]  A method of testing a press comprises operating the press ram against a load which is varied during the stroke so as to simulate the conditions obtaining during actual working operation. This is repeated for say 8 hours to complete the test. The press ram 3 is opposed by a piston in a cylinder 1. An auxiliary throttle valve 9 which controls the opening of a main throttle valve 5 in an exhaust line 4 from the cylinder is loaded to produce at any instant the desired resistance to the ram by means of a template 21 which is ,moved in dependence upon the position of the ram and which controls through a suitable linkage a spring which loads the throttle valve 9. A throttle valve 20 is interposed between the cylinder and the valve 9, and when valve 9 is unloaded, the valve 5 opens and liquid passes to the reservoir through the line 4, valve 5 and a line 13 and a valve 15. When the valve 9 is loaded, the increase in pressure between valves .20 and 9 loads the valve 5 which partially closes, and the cylinder is exhausted through the valves 5, 9. In a modification the valve 9 is loaded electromagnetically, the template 21 varying an electric resistance in a solenoid circuit. Valve 15 controls the rate of return of liquid to the cylinder 1 during upward movement of the piston, the liquid flowing to the cylinder through a non-return valve 14.

Title: Improvements in or relating to the manufacture of organic fluoro-halogen compounds
Inventor: MURAY JAN
IPC: C07C17/04
Filed: 1959-08-07
Abstract: Partially halogenated paraffins are prepared by bringing gaseous chlorine trifluoride into contact with a liquid partially halogented mono-olefine; the CIF3 acts as F2 + ClF, and these groups are added across the double bond in separate molecules of olefine.  The preferred molecular proportion of ClF3 is hence approximately one half of the olefine.  The ClF3 may be diluted with an inert gas such as nitrogen, at least in the early stages of the reaction.  The temperature is preferably raised during the reaction.  Examples react sym-dichloroethylene and trichloroethylene with ClF3 to obtain CHClF.CHCl2 and CHClF.CHClF, and CHClF.CCl2F and CHCl2CCl2F respectively.

After removing the oxide from the surface of the rolled strip it is annealed for one hour at 700 DEG C. in a vacuum.  The method is also applicable to similar and equivalent metals such as zirconium, hafnium, tantalum and columbium.

In a record controlled printing mechanism in which type-bars 1 (or racks which rotate type-wheels) are displaced in accordance with an additive combination code, the type selection occurs by the operation of one or more electromagnets 4A, 4B, 4C, 4D, whose operation releases corresponding latches 28 and sets operating pawls 31 so that when a box frame 38, 39 is moved down by a cam mechanism 43-48, setting bars 5, 6, 7 are operated to give an appropriate movement to the type-bars 1 through the links 21. Each electromagnet releases four latches 28 corresponding to four columns of characters, but on each cyclic movement only one latch is able to move since they are held by lugs 29 on four sequence bars 36 which are longitudinally displaced one at a time by cam mechanisms 73-77. There are a further four electromagnets and latch mechanisms so that eight columns of characters may be printed. If, as a consequence of the received combination code bar 7 is pulled down, a link 23 using a pivot 16 on bar 6 as a fulcrum lowers a bar 18 one third of a unit, but bar 1 is raised one unit due to the 1:3 ratio of the link 21. Bar 6 when lowered effects two thirds of a unit of movement to bar 18 and type-bar is given a movement of two units. Bar 5 may be moved either up or down and effects a four unit movement of the typebars 1 in either direction according to whether magnet 4C or 4D has been energized. Contacts 96-99 are provided to check in a comparing device that the typebars have been correctly operated. Hammer-impression arrangements. A cam 88, Fig. 6, driven by a chain and sprocket from the shaft 48 rocks, counterclockwise a plate 90 against the pull of a spring 91.
