The pressure roller 5 is made up of separate rollers 6 mounted on a shaft 10 carried by the carrier 4 which may be raised or lowered by a handwheel 25 in order to vary the pressure on the material or adjust for various thicknesses thereof; the carrier is pivoted by means of a chain drive 14 and piston-and-cylinder device 15. The carrier may be moved manually by a handle 16. In the modification shown in Fig. 5, the pair of rollers 6 are replaced by a tapered roller 5a; a pair of cylindrical rollers (6b), Fig. 8 (not shown), may be mounted, one on each side of the tapered roller, each roller being resiliently mounted in order that a gradual pressure is applied to the material during cutting. In the construction shown in Fig. 10, the table is formed from a sheet of flexible material, e.g. of steel, held at its ends in frame members (17c), Fig. 11 (not shown). A tapered roller 5c is mounted in a carrier 18c which is supported at its outer end during a stamping operation by means of a gear 22c running on a toothed rack (23c), Fig. 11 (not shown). The cutting-out pressure is resisted by a pivoted arm 4c which is normally stationary during cutting; the arm may be swung out-of-the-way by means of a handle 16c to facilitate the placing of the material and cutters on the table; the tapered roller 5c may be replaced by a cylindrical roller (5d), Fig. 12 (not shown), made up of separate disc-like rollers (6d). In the construction shown in Fig. 14, the pivoted arm 4e is provided with a tapered roller instead of the flat back-up surface 9c shown in Fig. 10. The rollers may be a synthetic plastics material, e.g. unplasticized P.V.C. (For Figures see next page.)

Title: Improvements in or relating to nickel electroplating baths
IPC: C25D3/12
Filed: 1968-05-15
Abstract: 1,236,811. Electro-deposition of satin nickel. HENKEL & CIE G.m.b.H. May 15, 1968 [May 16, 1967 and Aug. 26, 1967], No.22969/68. Heading C7B. Satin nickel is electro-plated on to an article as cathode from an aqueous acid nickel bath containing also a lustring agent and from 5 to 100 mg/l of a polyether where X represents oxygen, sulphur or an NH group, R 1  and R 4  represent hydrogen, a hydroxyl group or an organic radical, R 2  and R 3  represent an ethylene or propylene residue, and m,n, and p are whole numbers, which polyether at a temperature of from 40 to 75‹C. is able to form a finely dispersed emulsion, and effecting electroplating while the bath is maintained in that temperature range. As described the baths are Watts bath to which have been added aromatic sulphooxygen primary brighteners such as benzene-and naphthalene sulphonic acids, diaryldisulphimides, aryl sulphonamides, N-acetyl-o-toluene sulphonamide and saccharin. The polyether compounds include those classes specified in Specification 602, 591 but preferably are polyethylene oxide of M.W. 30,000; an ethylene oxide-propylene oxide mixed polymer of M.W. 10,000; ethylene oxidepropylene oxide mixed polymers reacted with other compounds containing functional groups; or polymers formed from propylene oxide and other compounds with reactive functional groups such as polyols. The stability of the emulsions employed are enhanced by the addition of low molecular weight surfactants such sulphates or sulphonates containing short chain alkyl groups, e.g. isohexyl sulphate, isopropylbenzene sulphonate, sodium hexyl sulphate. The plating current density may be from 0À5 to 10 amps/sq dm, and deposits may be provided directly on iron, brass, copper, nickel or plastic which has been made conductive.

Title: Improvements in and connected with carburetters for internal combustion engines
IPC: F02M7/11
Filed: 1924-09-29
Abstract: 246,539. Drayton, T. J. B. Sept. 29, 1924. Spray carburettors.-The pressure in the float chamber is varied in such a manner as to ensure the correct proportion by weight of air and fuel at all engine speeds and loads. The top of the float chamber has a vent to the atmosphere and to the air intake, and is in communication with the induction passage at a point near the throttle valve and also with the choke tube through a passage concentric with the nozzle. The float chamber a is sealed and supplies the nozzle d through a calibrated nozzle h, Fig. 3, duct k, well g, and duct d<1>. A supply tube l for a slowrunning nozzle f depends to the level of the well g. A tube m concentric with the nozzle d puts the top of the float chamber in communication with the choke tube through passages o, o', Fig. 2. The space around the slow-running jet is also in communication with the top of the float chamber through a duct p. A sleeve r surrounds a tubular extension 2 of a valve s which is rotatable by a handle u and is held on its seating by a spring t. The valve s, Fig. 4, has a diametral passage v and right-angled passages 1, z and 1<a>, y, the diametral passage forming the float chamber vent. When passages v, ware in register, air can flow past a valve x to the slow-running nozzle by way of ducts w, w<1>, y, 1<a>, Fig. 4, and 2a, r, Fig. 2. the mixture passing by way of ducts 1, z, 3 and 4 to the port 5, Fig. 1, at the edge of the throttle valve. A port 7 on the engine side of the throttle valve 6, Fig. 1, is in communication with the top of the float chamber through passages 8, 9, w<2>, Figs. 1 and 3. The port 7 may be dispensed with and the port 5 need not be closed by the throttle valve. During slow-running the strong suction exerted through the ports 5, 7 is nullified by air entering the float chamber through the tube m. At high speeds the vent v is incapable of admitting sufficient air to satisfy the suction through tube m and ports 5, 7, with the result that a lowering of pressure occurs in the float chamber. With an increase of load the suction at these points decreases and the pressure in the float chamber rises. Calibrated or adjustable orifices may be fitted at 5, 7, v, and m. Once these orifice areas are known a master jet h may be found which gives the correct fuel flow. If this jet be too large the tube m may be increased in size and vice versa. The valve s may be turned to close the vent v and stop the supply of fuel. The vent to the float chamber may be controlled in accordance with atmospheric conditions. Where the carburettor is fed with air under pressure, such air may be supplied to the vent v.

Title: Fertilizers
Inventor: DEE THOMAS PRIDE
IPC: C05B11/08
Filed: 1955-08-10
Abstract: A monocalcium phosphate-based fertilizer material is prepared by reacting phosphate rock in the presence of water and/or acid with an alkali metal or ammonium hydrogen sulphate, added as such or formed in situ by reaction between an alkali metal or ammonium chloride and sulphuric acid, the amount of hydrogen sulphate formed or added constituting at least 4.8 mols. per mol. of P2O5 in the rock.  If desired, potassium chloride may be reacted with sulphuric acid to form the hydrogen sulphate and the reaction mixture, if desired after removal of HCl, is added to the phosphate to be treated.  If water is employed it may constitute between 25 and 200 per cent by weight of the rock; the acids for example sulphuric, nitric or phosphoric acids when used, are preferably concentrated and their presence enables the amount of hydrogen sulphate to be reduced.  The reaction may be effected at room or elevated temperature and the final product may be ammoniated and granulated.ALSO:A process for the production of fertilizer material comprises reacting together phosphate rock and an alkali metal or ammonium hydrogen sulphate in the presence of water and/or acid, at least 4,8 mols. of the hydrogen sulphate being used per mol. of P2O5 in the rock.  Preferably potassium hydrogen sulphate is used and a suitable material may be produced by reacting potassium chloride with sulphuric acid and removing the hydrogen chloride formed.  The phosphate rock which may be finely divided is preferably calciferous rock, e.g. Merocco or Gafsa rock.  The process, which results in a product which has a high phosphate availability, converts all or part of the P2O5 present in the rock into monocalcium phosphate. The product may be ammoniated.

Abstract: 643,787. Sound recording circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 20, 1947, No. 23046. [Class 40 (iv)] In order to maintain a high signal to noise ratio in a sound record, the higher frequencies of the signals to be recorded are amplified relative to the lower frequencies when the power level is low and the relation amplification is decreased as the power increases. In the drawing, curves 1, 2, 3 show the proposed rotation between gain and frequency for normal, low and high power levels. The minimum gain 'occuring at 3000 c.p.s. on the high power curve is designed to reduce the effect of bad tracking. The record may be a disc record or, according to the Provisional Specification, a magnetic record.

Abstract: 706,139. Variable-speed gearing. WEINRICH, H. Oct. 4,1951 [Oct. 7, 1950], No. 23117/51. Class 80 (2)  In automatically-variable fluid-mechanical gearing, the input member of an epicyclic train is rigid with the driving shaft 1, the output member is rigid with the driven 'shaft 12, the intermediate member is rigid with the impeller 8 of a fluid clutch, and the turbine member 10 is so geared to shaft 12 that the impeller 8 and turbine 10 rotate in opposite directions, the turbine blades being located at the inner periphery of the fluid space. As shown in Fig. 5, the sun 6 is rigid with shaft 1, the carrier 2 with shaft 12, and the annulus 5 with impeller 8, while turbine 10 is geared through planets 14, carried by shaft 12, with fixed annulus 16. Alternatively, however, the annulus 5 may be rigid with shaft 1 and the sun 6 rigid with impeller 8, or carrier 2 may be rigid with shaft 1, annulus 5 with shaft 12, and sun 6 with impeller 8, in which case turbine 10 is geared to annulus 5, through reversing idlers and the shafts 1, 12 are both at the same side of the gear. In Fig. 6, provision is made for reversal of shaft 12, the carrier 18 of planets 14 and the annulus 16 being freely rotatable and adapted to be moved axially in opposite directions through levers 39, 41 under the control of a double cam 37. In the forward - running position shown, annulus 16 is at the left, where it is coupled by teeth 36 to the fixed casing 9, and carrier 18 is at the right, where it is coupled by teeth 33 to a flange 35 of shaft 12. For reverse drive, annulus 16 is moved to the right, so that it is coupled by teeth 40 to flange 25, and carrier 18 to the left, so that it is coupled by teeth 45 to casing 9. An oil pump, driven by shaft 1, may supply oil through bores in the shafts to the bearings and gears and to the clutch. Radial vanes may be formed at 26, Fig. 5, on the hub of the impeller 8 to force oil outwards and prevent cavitation. In Fig. 5, however, air is used as the clutch fluid instead of oil, and this air is continuously renewed, so as to promote cooling, the air escaping through ports 27 at regions of high pressure and entering through ports 32 at regions of low pressure.
