Title: Improvements in or relating to potassium nitrate and compositions containing it
Inventor: AMES JACK
IPC: C01D9/20
Filed: 1953-06-12
Abstract: Alkali metal salts of disulphonic acids of dinaphthylmethane are prepared by heating under reflux a mixture of naphthalene sulphonic acid and formaldehyde in the presence of sulphuric acid and water and neutralizing the resulting liquor with an alkali metal hydroxide solution.  Dependent upon the naphthalene sulphonic acid employed, salts of a  : a 1-disulphonic acid of dinaphthylmethane or b  : b 1 or a  : b -disulphonic acid of dinaphthylmethane may be obtained. The salts are employed as crystal modifiers for potassium nitrate (see Group III). Specification 656,048, [Group III], is referred to.ALSO:Potassium nitrate having a reduced caking tendency consists of crystals thereof bearing a surface deposit of a salt soluble in a saturated aqueous potassium nitrate solution at 20 DEG C. of at least one compound definable as the condensation product of 1 mol of formaldehyde and 2 mols of a naphthalene monosulphonic acid, i.e. a salt, preferably sodium, of disulphonic acids of dinaphthyl methane. The sodium or other soluble salts of a :a 1, b :b 1 or a :b disulphonic acids or dinaphthyl methane may be employed, depending on the naphthalene sulphonic acid which is condensed with the formaldehyde, and the amounts employed should be at least 0.025 per cent and preferably 0.05 to 0.1 per cent of the dry weight of the nitrate.  The surface deposition may be effected by dissolving a soluble salt of the dinaphthyl methane disulphonic acid in the aqueous solution from which the potassium nitrate is to be crystallized or the salt may be dissolved in water and sprayed or otherwise distributed over previously formed potassium nitrate crystals, after which the water is evaporated whilst agitating. Examples relate to the incorporation of 0.1 per cent of the sodium salt of b :b 1 and a :b  disulphodinaphthylmethane in an aqueous nitrate solution from which the nitrate is crystallized with agitation, and to the use of 0.5 per cent of the sodium salt of b :b 1 and a :a 1 disulphodinaphthylmethane applied as a 10 per cent aqueous solution spray to potassium nitrate crystals.  The effect of the addition of the above salts is comparable with that of the dyestuffs of sulphonated aromatic character disclosed in Specification 656,048, which is referred to, in that the strength of the bridges of recrystallized material which form between adjacent particles of potassium nitrate is reduced.

Abstract: 1,261,755. Adjusting vehicle suspension height. BOGE G.m.b.H. 28 March, 1969 [28 March, 1968], No. 16433/69. Heading B7D. [Also in Division G3] Fluid in a vehicle suspension system is regulated by switching devices controlled by the charge on a single capacitor 31, the charge being determined by the operation of a threeposition switch 15 actuated by the relative positions of two members (axle 3 and chassis 1)À As shown, the switch has two contacts 19, 20 connected to supply and earth respectively, with a dead-band between formed by an insulated section, but in Fig. 2 (not shown) the dead-band portion also has a contact connected to an intermediate voltage. An arm 23 of the switch is connected to the capacitor through a resistor 28 and the arrangement is such that normal -movement of the suspension causes alternate charge and discharge of the capacitor, which thus attains an intermediate voltage (like that definitely provided by the dead-band section of Fig. 2). If the. axle to chassis distance is outside limits the voltage on the capacitor either drops below a lower limit, to thereby trip a transistor Schmitt trigger switching circuit 34 to start a fluid pump motor 14, or it rises above an upper limit to thereby trip a similar trigger 44 to open a fluid-release valve. This may be a separate solenoid valve 13 or alternatively the pump can be of reciprocating type which can, by segmented slip rings on the motor coupling, be arranged to stop with its piston uncovering a fluid-release port. With this pump, when the switch is in the dead-band region, the piston is stopped at top dead-centre, blocking the port (Figs. 3, 4, not shown). In Fig. 5 (not shown), the three-segment switch is used and different resistors are placed in series with the capacitor for each segment.

Title: Presses for working materials under predetermined temperature conditions
Inventor: TROZMULLER FRIEDRICH JOSEF
IPC: B30B15/28
Filed: 1947-06-25
Abstract: 648,966. Moulding presses. SEMPERIT GUMMIWERKE AKT.-GES. June 25, 1947, No. 16773. Convention date, Dec. 5, 1941. [Class 87 (ii)] [Also in Groups XVI and XXIX] A safety-device for a press with electricallyheated press-plates, for preventing the actuation of the press outside a permissible working range of temperature, comprises a temperaturesensitive member provided in a heated pressplate, a relay switch controlled by the temperature-sensitive member, and means operated by the relay switch for preventing actuation of the press when the temperature of the plate is below the permissible temperature range. The relay switch may act to break the circuit of an electric motor which (directly or through a hydraulic pump) actuates the press, or may lock or clamp a movable part of a press to prevent operation thereof. The drawing shows the invention applied to a manually-actuated eccentric press having an electrically-heated press-plate 1, the temperature of which is controlled by a thermostat 2, 8. The temperaturesensitive member mounted on the plate is a bimetallic member comprising a bar 14 disposed in a sheath 15 and controlling a switch-lever 16 working between contacts 17, 18. The contacts are connected to a relay 20 which opens and closes the circuit of a solenoid 22, the core 23 of which is pivotally connected to a threearmed lever 24, one arm 25 of which has a detent 26 which can engage a ratchet-wheel 27 mounted on the eccentric shaft of the press. When the temperature of the plate 1 is below the permissible temperature range, the switch lever 16 rests on contact 17 and closes the switch 21 of relay 20, thus energizing solenoid 22 to hold the ratchet-wheel locked in the full-line position shown. When the temperature of plate 1 rises to a point within the range, bar 14 lengthens relative to its sheath 15 and removes lever 16 from contact 17, thus de-energizing relay 20 and solenoid 22 and allowing a spring 28 to pull lever 24 to the broken-line position, thus unlocking the ratchet-wheel, whereupon the press can be operated. When the temperature of plate 1 rises to a point above the range (which may happen if thermostat 2, 8 fails), bar 14 lengthens to connect lever 16 to contact 18, thus locking the ratchet-wheel as before. The plate may be provided with two temperature-sensitive members, each being connected to its own relay, one relay stopping the press when the plate is too cold and the other when it is too hot. The solenoid 22 may operate an acoustic or optical signal. If the device is provided on a motor-operated press, the relay 20 may act on the motor circuit. In a modification (not illustrated) a mercury-switch thermometer may act on a relay to lock or release the press.
