Filed: 1929-03-12
Abstract: 307,755. Soc. Belge du Caoutchouc Mousse. March 12, 1928, [Convention date], Void [Published under Sect. 91 of the Acts]. Spring surfaces; mattresses. - cushions and like resilient bodies are formed of super posed plates or layers of cellular material having spaces therein to permit ready deformation. The plates are preferably of grid-like formation and the bars of the grids may be of rectangular or other section, being preferably " waisted " as shown in Fig. 12. There are preferably two series of layers or plates alternating one with the other and of the same or different shapes; or either or both layers may consist of independent bars or blocks and the arrangement may be such that the bars in alternate layers of one series are in staggered relation to the bars in the other layers. The material used for the plates or bars is preferably cellular rubber and the parts of the structure may be secured by adhesives or by tying.

Title: Process for the manufacture of highly porous silica-lime stones
IPC: C04B28/26
Filed: 1936-03-17
Abstract: In the method of producing porous silica-lime stones by mixing kieselguhr, slaked lime and between 50 and 90 per cent water and hardening the mixture with steam under pressure, segregation is prevented during the shaping and hardening by providing that 1-5 per cent of the silica is present in solution.  The soluble silica may be added as such, e.g. in the form of water glass, and/or it may be produced in situ, e.g. by additing caustic alkali. Thickening agents, e.g. dextrine or glue, may also be added in amount up to 4 per cent of the total dry content.  Fillers, e.g. pumice, gravel, cork fragments and animal, mineral, or vegetable fibres such as pigs' hair, wood pulp, wood shavings, straw, reed tube, or asbestos, may also be added.

Title: Improvements in or relating to milling machines for grooving or fluting twist drillsand the like
IPC: B23C3/32
Filed: 1919-04-01
Abstract: 144,418. Birmingham Small Arms Co., and Pardoe, E. O. April 1, 1919. Milling helical surfaces.-In a machine for milling the grooves in twist drills or the like, the work spindle 2, is rotated by gearing 4, 17, from a shaft 16 carrying a cam 18 to feed the work spindle longitudinally, at a constant or varying speed. The cam 18 preferably has two replaceable steps 19 and is geared to the spindle 2 so that the latter makes one or more complete revolutions plus half a revolution during each forward movement, so that the drill is indexed for cutting the second groove at the end of the first return stroke. The spindle 2 is rotatably mounted in the sliding collar 13 carrying the cam roller 15, and is returned by a spring 11 in an extension 12 which may act as a dash-pot. One cam piece 19 has a recess so that at the end of the second return motion of the spindle 2, the collar 14 moves back far enough to engage a trip lever 42 and release a clutch 43 thus stopping the feed mechanism. The cutter spindle is carried by an angularly adjustable bracket 21 mounted on a vertical slide 31<a> operated by a cam 32 to vary the depth of the groove, and raise the cutter during the return stroke of the drill. The slide 31<a> is adjusted by a screw 37, and a spring 35 holds the roller 33 against the cam 32. The cutter 23 works in a slot in a support 40 for the drill.

Title: System for Measuring Cross Power Spectra or Cross Correlation Function
IPC: G06G7/19
Filed: 1967-02-21
Abstract: 1,179,711. Evaluating correlation functions. USTAV PRO VYZKUM MOTOROVYCH VOZIDEL. Feb.21, 1967 [Feb.22, 1966], No.8143/67. Heading G1U. A system for developing co-efficients for use in evaluating the cross power spectrum or cross correlation function of two functions x(t), y(t), incorporates two phase shifting networks 2, 5 to which the two functions are applied as inputs, the phase shifters operating to establish a phase difference of either m# or (2n + 1)#/2 between the two functions, which are then combined in an adder 7. The outputs from the adder are passed to a band pass filter set 9 whose output is applied to an r.m.s. detector 11. It may be shown that the cross power spectrum Sxy(jwo) may be calculated from the two r. m. s. values M 1 , M 2  derived from the arrangement for the inphase and quadrature settings of the phase shifters respectively in accordance with the equation: Where A, B are the transmission constants of the system and Wo is the mean angular frequency in the transmission band, #f of the filter set. Alternatively by determining M 1  and M 2  in the different frequency bands within the range covered by the filter set, the cross correlation function may be determined from the expression: where M 1 (W oi ) and M 2  (W oi ) are the in phase and quadrature outputs in frequency band i, N is the number of filters and W hi , W di  are the upper and lower limit frequencies of the band i.

Title: Improvements in process for the treatment of silicates with acids in order to obtaintheir soluble salts
IPC: C01F7/20
Filed: 1933-03-20
Abstract: In a process of decomposing silicates, chiefly those containing the alkali metals sodium, potassium and lithium, by acid vapours such as of hydrochloric or nitric acids, the silicate and an aqueous solution of the acid are placed in the higher and lower parts respectively of a closed container; the liquid is heated to produce a vapour which condenses over the silicate, the condensate with the dissolved substances falling into the solution.  The silicate may be admixed with substances capable of facilitating the reaction, e.g. kaolinised leucite.  In an example, ground or granulated leucite is placed in a perforated container which is introduced into the top of a vertical tubular pressure-resisting autoclave which may be lined with grit sandstone.  Slightly less than the theoretical quantity of nitric acid is used.  Electric resistance, steam or direct fire heating is employed.  The top of the autoclave may be slightly cooled, and the silicate may be periodically sprayed with liquid acid.  The temperature should be maintained above 100 DEG  C. to obviate the production of gelatinous silica, and preferably between the decomposition temperatures of iron and aluminium nitrates, viz. 125--140 DEG  C.  Any iron in the solution is precipitated under pressure by, say, potassium ferrocyanide, and removed, preferably by passage through the exhausted leucite.  This is replaced by a fresh batch, and the hot solution in the autoclave evaporated to the desired extent by releasing the pressure, any residual acid vapours being removed by the fresh leucite.  The potassium and aluminium nitrates are separated in known manner.  Specification 401,567 is referred to.

Abstract: 792,192. Adding powdered material to molten metals. LEDLOY, Ltd. Sept. 5, 1955 [June 3, 1954], No. 8399/54. Class 82(1) [Also in Group XXX] Solid materials such as lead, lead alloys or lead compounds, are added in subdivided form to a stream of molten metal by propelling the material from a storage container along a feeding duct which is connected to one part of the container and has a discharge opening in proximity to the liquid stream, the propulsion taking place under pressure of a gas supplied to the container at a position spaced from the end of the duct connected thereto. The duct has a discharge passage with a bore less than, the bore of the duct at the point of connection with the container, the bore of the discharge passage being sufficiently small, having regard to the size of the particles to be discharged, to retain the material against gravitational discharge when the gas pressure is cut off. In the apparatus shown in Fig. 1 material is supplied as required from hopper 22 to container 10, valve 23 is then closed and gas pressure is applied from the duct 13 forcing the material into and through duct 18. The discharge end of the duct has a tapering portion 21 and a constricted orifice 20. For use with lead shot of particle diameter 0.01-0.05 inch the tube 18 may have a bore of 1 inch and the constriction 20 a bore of 3/16 to 1/4 inch. The constricted portion may extend from the outlet over more than half of the length of the duct. Fig. 2 shows such a modification in which the feed duct 27 has a restricted diameter, e.g. “ inch, in relation to the bore 25 adjacent the point of connection of the duct with the container. The duct is conneted to the container through an orifice 20 a bore of 3/16 to 104 inchfl The constricfications a valve 14 is inserted between the container and the duct to prevent discharge of material when the apparatus is not in use.
