Patent GB-147588-A (GB)
Title: Improvements in and relating to automatic weighing apparatus for loose substances including liquids
IPC: G01G13/00
Filed: 1920-07-08
Abstract: 147,588. Bruhn, G. A. July 12, 1917, [Convention date]. Automatic-feed weighers.-In an automatic weighing-apparatus particularly for use in the production of superphosphate from crude phosphate and sulphuric acid, the control of the filling and emptying devices for the weighing receptacles is effected by means of a cam-shaft which is temporarily coupled to a continuously-revolving worm shaft by the movement of the weighing-receptacles. The weighing-receptacles l, m for sulphuric acid and phosphate respectively are mounted on weigh-beams n, o and the operations of the feed ard discharge valves are controlled by the cam-shaft e. A continuously rotating shaft a drives a stirrer shaft c in the phosphate feed hopper and also a shaft d by means of a countershaft b and chain gearing. The acid enters the receptacle l by a pipe 25, and as the receptacle sinks, a bent lever 42 connected thereto gradually reduces the feed by operating a valve 31. At the balancing point a catch 46 is liberated from a lever 44 carried down with the receptacle, and a weighted lever 45 falls, knocks back a catch 35 and thus allows a bar 40 to fall and close the valves 31, 32. At the same time, the lever 45 withdraws a slide 48 from the path of a lever 8 which tends under the influence of a spring to couple a loose worm 6 to the rotating shaft d and consequently to drive the cam-shaft e. This coupling-up is prevented, however, until a similar slide 62 is withdrawn by the cutting off of the phosphate feed to the receptacle m, this cut-off mechanism being similar to that described in connexion with the acid receptacle l except that the feed-reducing mechanism is dispensed with. The lever 8 now couples up its clutch and the camshaft e rotates. Cams 16, 17 open the discharge orifices of both receptacles, and the material passes into the stirring vessel f, a series of light blows being delivered against the receptacle m to assist its discharge. Cranks g open hinged flaps i alternately to discharge the mixed material. The cams on the shaft c restore the various parts to their original positions and another cycle of operations is commenced. After the initial movement of the cam-shaft e, a second clutch on the shaft b is allowed by the cams 12, 13 to engage the worm b and this clutch continues the rotation of the cam-shaft after the uncoupling of the first clutch until after one revolution the cams 12, 13 throw the second clutch out of action. A counter indicates the revolutions of the shaft e and consequently the number of weighings.

Title: Improvements in or relating to weighing machines
IPC: G01G23/26
Filed: 1945-07-31
Abstract: 605,879. Weighing apparatus. DOUGLASS, M. J., and DOUGLASS, K. H. July 31, 1945, No. 19569. [Class 143] A weighing-machine comprises a spring having weight bearing means connected thereto, an indicating pointer or drum two operating means alternatively engageable to translate deflections of the spring to the pointer or drum and to move the latter in the same sense relative to a zero or index on deflection of the spring in opposite directions, and means for engaging at will either of said operating means. A clutch may be provided in the operating means having a release device whereby the pointer or drum may be set to the zero or index. The pinion 4 which transmits motion to a pointer 6 or drum on the spindle 8 can be engaged by either of two racks 10, 12 pivoted to the plate 14 provided on the lower coupling 16 of the main springs. The racks are coupled by spindle 18 and spring 20, and brought into operation by means of a click-over switch 24 which swivels between stops 25, 27 and is held by a spring 32 on arm 28 carried by swivelling boss 26 and passing through a similar boss 30. The switch is operated by arm 34. A sleeve 36 carries the pointer 6, which has clamping jaws fitting a groove therein, and a heart-shaped cam 38. A flange 46 keyed to the spindle 8 is faced with cork or other material to give a driving fit with the pointer, which may also be faced. A spring-pressed collar 54 can be retracted by pressure on a lever 59 freeing the sleeve and pointer for rotation. A plunger 60 is constructed to release the clutch and rotate the cam 38 to bring the pointer back to zero. The plunger spindle is in two parts connected by a sleeve 68 which slides on the lower part 74, a pin and slot 76, 78 limiting the motion. Depressing the plunger first causes the bottom of the spindle to impinge on the cam 38, the sleeve then contacting the clutch lever 59 to release the clutch and allow rotation of the cam. When rack 12 is engaged, downward movement of the load gives a reading in the ordinary way. With rack 10 engaged, a similar reading is produced by upward movement of the load. Thus the weight of any load removed is registered. The plunger 60 is operated to set the pointer at zero after a container has been placed on the apparatus to give a direct reading after a load has been applied or is operated after applying a load when a direct reading is given of any load subsequently removed.

Title: Apparatus for sealing the passage through a duct
Inventor: COCKERILL JOHN ROBERT
IPC: F16L55/10
Filed: 1965-05-10
Abstract: 1,110,063. Stopping pipes. IMPERIAL CHEMICAL INDUSTRIES Ltd. 3 May, 1966 [10 May, 1965], No. 19624/65. Heading F2P. Adjacent sections 11 and 21 of a duct having external end flanges 9 and 10 are adapted to be blanked off by a sealing gate 1, said gate being interposed between the duct flanges and rectilinearly movable between two positions in which a hole in the gate and a solid plate part of the gate are respectively brought into axial alignment with the duct, said hole and solid plate part having at least the same cross-section as that of the duct. Hydraulic jacks are detachably secured to and between the sections of the duct to effect relative axial movement therebetween. The duct may be rectangular in cross-section and may have a cross-sectional area ranging between 16 and 400 sq. ft. As illustrated in Fig. 1, the gate is formed from a channel frame having cross-members 2 and 3, the solid plate part 4 of the gate being reinforced with stiffeners 5. Normally the gate is positioned by bolts 12 between the flanges of the duct sections with the hole therein in alignment with the duct passage to allow flow therethrough. When it is desired to blank off said passage, the bolts 12 are released and four double-acting jacks 15 (only one being shown) are actuated to force the flanges apart. The gate is then moved, preferably by remote control means such as a pulley system, so that the solid plate part 4 blanks off the duct. The jacks are then oppositely actuated to clamp the gate between the flanges and the bolts replaced. Then the jacks may, if desired, be removed. The gate may be slidably guided by rollers in a cage arranged around the duct. The duct is preferably formed by several sections, one including an expansion joint such as a metal bellows or cloth or fibre-glass packed joint to facilitate axial movement of the flanges 9 and 10.

One type of element is shown in Fig. 23 and consists of a base 40 made of roofing felt or other composite material covered with metal such as copper 42. Slots 41 give the appearance of three separate shingles when the element is partly covered by the elements of the next course. The metal covering 42 is extended in the form of tongues 44, which show through the slots in the adjacent elements. Fig. 29 shows in section a different type of element, which consists of a non-metallic base 45 and a metal shell 46, the rear edge of which may taper until it lies flush with the base, or, as shown in Fig. 29, it may be formed with a flange 53 and an extension 54, which is covered with a plate 55. The space between the shell 46 and base 45 is filled with an adhesive plastic material 61, such as asphalt. Such shells 46 are placed in a conveyer, shown in Fig. 20, having pairs of sections 87, 83, the sections 87 having concavities of the shape of shells. The conveyer passes several stations at which various operations are performed on the shells. At the, first station, the shells are filled with plastic material 90, and at the next the bases 91 are placed in position. These may be cut to shape and size beforehand, or they may be cut from a roll of the base material placed near the conveyer. The bases are then covered with talc and turned over on to the flat sections 88 of the conveyer. The cover plates 55 are then placed in position, a further quantity of talc applied, and the bases coloured, the completed elements being finally subjected to a burnishing operation.

Title: Improvements relating to high frequency heat treating apparatus
IPC: H05B6/48
Filed: 1945-07-31
Abstract: 623,000. Dielectric heating. EVERY, C. E. (Mittelmann, E.). July 31, 1945, No. 19639. [Class 39(iii)] [Also in Group XXXV] A dielectric heater, especially for thermoplastic pieces 24, comprises a H.F. generator with a frequency determining parallel resonant circuit having a capacitive branch and an inductive branch, the heater unit 28 for the pieces being included in the capacitive branch; and the circuit has such constants that the capacitive impedance of the heater unit is a relatively small fraction only of the total capacitive impedance of the capacitive branch in which it is included. Thus changes in the dielectric being heated do not substantially affect the frequency of the circuit. A switch 50 is closed against a spring by a lug on a handle on a hinged cover 26 carrying a plate electrode 28 of the heater so that current is supplied only when the cover is lowered on the pieces 24 which are placed on a non-conductive shell 22 above two plate electrodes 16, 18. The plate electrodes 16, 18, 28 of the heater comprise a pair of series connected condensers, and the plate 28 is earthed. Plates 16, 18 are connected respectively to adjustable condensers 66, 68, which are connected to plates of oscillator tubes 78, 80 and to opposite ends of a tank coil 82, the mid-point of which is earthed. The positive terminal of the power supply rectifier unit 118 is also earthed through an ammeter 8. The electrode 28 and the mid-point of the coil 82 are thus at the same substantially zero direct current potential. A power absorption meter 10 is coupled to the circuit through a potentiometer 14 connected to the measuring thermocouple through condensers 132 connected to tappings 134 of the tank coil 82. The wattmeter 10 may have a time scale indicating time required for the heating as well as the power scale. Specification 578,556 [Group XXXV], is referred to.

The dyes may be prepared by known methods according to the following schemes : when R 1  is -alkylene-X when R 2  and/or R 3  is -alkylene-X or When -X is acylamido, an N-aminoalkylnitrophenylenediamine is acylated on the free aliphatic amino group, or alternatively an N-aminoalkyldinitro - aniline may be acylated followed by reduction of one of the nitro groups. When -X is -NHCONH 2  the said aminoalkyl derivatives may be reacted with potassium cyanate in a solvent or fused with urea, when -X is -NHCSNH 2  they may be reacted with CS 2  and NaOH to form the dithio-carbonate which is converted to isothio-cyanate with ethyl chloroformate and this is reacted with dry NH3. When -X is a sulphamoyl group 2,4-dinitrochlorobenzene is reacted with an aminoalkane sulphonic acid, e.g. taurine, which product is converted with PCl 5  to the N-chlorosulphonylalkyl-2,4-dinitroaniline which by reaction with NH 3  or amine forms the desired dye. An alternative method of making the dyes is to react a nitrophenylene diamine with a compound having a double bond activated by X e.g. acrylonitrile, methyl vinyl ketone or methyl vinyl sulphone. Examples of the preparation of a number of dyes are given.
