Title: Stable, gelling, acidic hydrous silicates
IPC: C01B33/46
Filed: 1944-11-15
Abstract: Stable acidic hydrous silicates capable of forming gels and films are prepared by contacting an aqueous dispersion of naturally occurring silicates capable of forming gels and films with an organic cation exchanger in its acid form and separating the exchanger from the dispersion.  Examples of such silicates are bentonite, montmorillonite, stolpenite, erinite, steargillite, deweylite, beidellite, saponite, metabentonite, hectorite, magnesium silicate wax, halloysite, allophane, collyrite, schrotterite, lucianite, sepiolite and spadaite, generally containing kaolin, calcium and magnesium carbonates, feldspar, silica &c.  Coarse materials may be separated from the dispersion by washing, screening, settling or centrifuging prior to the addition of the cation exchanger.  Gases may be removed by boiling, if desired under reduced pressure. Dispersions containing from 0.1 to 5 per cent., and in some cases, up to 12 per cent., by weight of natural silicate may be employed. Suitable cation exchangers are the hydrogen form of sulphonated carbonaceous exchangers (sulphonated coal, lignite, peat &c.) or of sulphonated or sulphited insoluble phenolaldehyde resins for example, those made from phenol, diphenylol sulphone, catechol, phenols as found, e.g., in quebracho, and an aldehyde, particularly formaldehyde having sulphonic groups in the ring or on methylene groups.  Examples under various trade names are specified.  The exchangers where necessary are converted to the acid form by washing with hydrochloric, sulphuric, formic &c. acid.  Addition of increasing quantities of exchanger depresses the pH value to a lower value of about 2.  Various examples are given.  The products are suitable as catalysts for petroleum refining or cracking, and the acid get may be coagulated by uranyl, thorium auric, ferric or manganous nitrates, zirconyl chloride, ammonium complexes containing tungsten &c.  The gels are also of use in the preparation of ointments &c. (see Group VI), in moulding sands, for finishing leather, for clarifying fruit juices, wines, honey, vinegar &c., and treated with basic organic materials or heavy metal ions they develop water resistance and good dielectic properties.  Specification 16598/44 (as open to inspection under Sect. 91) is referred to.ALSO:Acidic hydrous silicates prepared from naturally occurring silicates capable of forming gels and films (see Group III) are useful for purifying or clarifying fruit juices, wines, honey, vinegar &c.ALSO:An acidic hydrous silicate prepared from naturally occurring silicates capable of forming gels and films (see Group III) is of use as an ointment base, and may be compounded with for example, permanganates, or with chloroamides for skin decontamination against vesicants, or with sulphonamides, including sulphanilamides, tannic acid, biotin &c. for treating burns.  The gels containing permanganates may be used for detoxifying certain oxidizable war gases.  The acid silicates are also useful for purifying or clarifying fruit juices, wines, honey, vinegar &c.

Title: Conveyor System
Inventor: PHILLIPS PETER JON
IPC: B65G23/00
Filed: 1967-05-17
Abstract: 1,161,542. Drives for belt conveyers. HEWITT-ROBINS INTERNATIONAL S.A. 17 May, 1967, No. 22866/67. Heading B8A. [Also in Division H2] The torque/speed characteristics of head and tail drives, including electric motors, for a conveyer belt are so selected that the drives apply differential torques to the belt, which torques act in opposition or in the same direction, depending whether the action of gravity on the load on the conveyer is or is not acting to increase the speed of the conveyer, so as substantially to compensate for unequal tension forces introduced by the weight and distribution of the load on the conveyer. In one example, a head motor 21 is provided with a control 34 and an eddy current coupling 22 between the motor and the belt drive is adjustable. A motor 29 with a control 30 drives the tail end of the conveyer and brakes 25, 31 are provided. With a 100 H.P. 3% slip characteristic tail drive motor, a 50 H.P. 8% slip head drive motor and a load A as shown in Fig. 1, an average estimated belt tension of 6000 pounds and a horse-power of-50 is required. The latter results from 25 H.P. drive applied by the head motor and a resistance of-75 H.P. applied by the tail motor and is shown graphically in Fig. 4. The effect is to resist the tendency of the descending load A to cause loss of belt tension. With an increased descending load, Fig. 2 (not shown), the belt speed rises but is stabilized and the tension maintained due to an increase in the resistance to -109 H.P. by the tail motor. With the load entirely on an uphill slope, Fig. 3 (not shown), a total positive application of 84 H.P. is necessary at a reduced speed (see Fig. 4). A counterweight 2 provides adjustment for changed belt lengths due to stretch or contraction. In a further construction, Fig. 5, a master counterweight system 52 is supplemented by a slave system 54 which during starting, provides tension at the tail 53. The differential drive may be obtained by using different gear ratios for the two drives in Fig. 1. Alternatively different pulley diameters and connections having different slippage characteristics can change the ratios between the drives.

Heading B1D. A filter press for separating suspensions comprises several plano-concave filter plates 3 arranged vertically side by side between pressure plates 1, 2 with a band of filter cloth 4 passing in zig-zag fashion between adjacent plates and around their respective rollers 5, 6 and 7 so that the cloth is doubled upon itself within each chamber 8 formed by adjacent plates. A suspension is passed into the chambers 8 whilst pressure fluid is forced between each plate flat surface B and a connected elastic watertight diaphragm 9 to compress the solids into a cake whilst the liquid escapes via the filter cloth and the front perforated face A of the plates (which may also be fluted). To remove the cake after drying the plate 2 is withdrawn to its Fig. 5 position whereupon each plate e.g. 3a is likewise moved so that filter cloth length a takes up the prior position of portion b, such movement causing the downward expulsion of the cake. The "other" fresh side of a is now ready for the subsequent separation. Filter cloth regenerat- or 18 is incorporated. The size of the filter cake can be varied by the pressure fluid supplied between the diaphragms 9 and the plates.

Title: A control mechanism for spring forming machines
IPC: B21F3/04
Filed: 1956-07-26
Abstract: 797,481. Coiling springs. HACK, K. July 26, 1956, No. 23084/56. Class 83 (4). A spring-forming machine for the manufacture of coiled wire springs with straight arms at the ends disposed at an angle to each other and having a winding tool which is moved so that a length of wire fed thereagainst is coiled thereby is characterized in that a rotating compound cam disc, which moves the tool forward to start the coiling and back to stop the coiling, comprises two coaxially arranged cam discs with different rates of rotation, of which the more rapidly rotating cam disc carries the forward and return cams for advancing and retracting the winding tool and the slower rotating cam disc carries a cam for holding the tool in its advanced position for a selected number of windings of the spring. Spring wire stock 1 is fed by rollers 2 through a guide 3 as far as a leading arm or end 1a of the spring requires. A coiling tool 4 shortly before this length is reached, moves down to engage the wire 1 which coils thereagainst in its continued feed until the desired number of coil turns have been formed. The tool 4 then rapidly retracts and the coiled spring moves forward until a trailing arm or end 1b of the spring has the desired length, whereupon the wire feed is automatically interrupted and a parting knife 5 cuts off the finished spring over an anvil 7 which has been moved into position. Movement of the tool 4 is controlled through adjustable linkages 27, 25, 22 and 21 and camfollower roller 19 by rotating cams. A slowrotating cam comprising two circumferentially adjustable cam elements 30a, 30b is fixed to a rotating shaft 7 and serves to hold the coiling tool 4 in its forward coiling position. A fast rotating cam on a hub 13 (not shown), rotated through gearing at an integral number times the speed of the slow cam, comprises two circumferentially adjustable segments 15, 17 which cause the forward and retraction movements of the tool 4 when the follower roller 19 is off the slow cam elements 30a, 30b. One spring is made for each rotation of the shaft 7.

Filed: 1935-08-20
Abstract: 461,961. Automatic firearms. JACKSON, L. MELLERSH-. (Mauser-Werke Akt.-Ges.) Aug. 20, 1935, No. 23400. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 21, 1936.] [Class 119] Relates to automatic pistols or like firearms having a cock 37, a spring sear 59 therefor, a trigger 14, and a connecting rod 22 extending from the trigger to co-operate with the cock and sear. According to the invention, the connecting rod has a lifting cam 55 adapted to co-operate with an intermediate member such as a vertical slide 50, Fig. 1, the upper end of which bears under the breech-block 40, so that the firing mechanism cannot operate unless the breech is closed, when a recess 52 in the breech-block allows the slide 50 to rise, thereby permitting the action of the connecting rod as follows. During the first part of the pull of the trigger, a lateral projection 57 at the rear end of the connecting rod is in engagement with a lug 58 on the cock, and the cock is thereby cocked and engaged by the sear 69 ; and during the further pull of the trigger, the cam 55 comes against the bottom of the slide 50, causing the connecting rod to be depressed and its projection 57 to fall below the lug 58, whereupon a shoulder 68 on the connecting rod bears on a lug 60 on the sear and the sear releases the cocked cock. When the breech is not closed, the cock cannot be cocked because the recess 52 in the breech-block is not in line with the slide 50 and this depresses the connecting rod 22 and disengages it from the lugs of the cock and sear. In addition, a twoarmed lever 81, 82, Fig. 6, may be pivoted at 79 and provided near its pivot with a wedgeshaped projection 83 against which the magazine 85 bears when fully inserted to render the lever inoperative. If the magazine is not fully home, a spring 80 rocks the lever to bring a hook 87 thereon into engagement with a lug 88 on the connecting rod 22 to prevent its operation, and at the same time the rear end 91 of the lever engages a shoulder 94 in a recess 95 in the breech block 40 and retains this in the open position. The wedgeshaped projection 83 also acts as a cartridge ejector. The Specification as open to inspection under Sect. 91 comprises also the subjectmatter of Specifications 453,020, 455,395, and 457,943, and in addition describes a modified construction of the device for putting the firing-mechanism out of action when the magazine is removed. This subject-matter does not appear in the Specification as accepted.
