Title: Improvements in and relating to rheostats and potentiometers
IPC: H01C10/32
Filed: 1938-02-07
Abstract: 510,796. Variable resistances. INTERNATIONAL RESISTANCE CO. Feb. 7, 1938, No. 3839. Convention date, Feb. 19, 1937. [Class 37] In a variable resistance wherein a strip of insulation carrying the resistance material, e.g., a coating, is mounted on a dielectric base, a heat-conducting plate is disposed between the base and the strip to facilitate cooling. The dielectric cylindrical base 10, preferably a phenolic condensation product, has an upstanding peripheral ridge 11 within which a metal, e.g., a copper plate 35 and the insulation strip 34, are nested and secured by rivets 48, 49, 56, 57. A resistance coating 54, e.g., carbonaceous material suspended in a binder such as varnish is applied to the strip 34, as shown in Fig. 1, leaving an insulated portion 55 for the rivets 56, 57, and to enhance heat transmission to the plate 35 a heat-conducting medium may be applied between the strip 34 and plate 35, or these may be bonded together. The end portions of the insulation strip 34 adjacent the ends of resistance 54 have conductive coatings 46, 47, connected by the rivets 48, 49, to terminals 50, 51. A spring contact 58 is secured to a raised portion 19 of the dielectric base 10 between flanges 20, 21 thereon, by a rivet 59 extending through base 10 and headed over on the central terminal 60. The free end of contact 58 bears at 61, Fig. 3, on a contact plate 62 on an insulating arm 32 carried by the adjusting spindle 31 and is electrically connected to the brush 33 which wipes over the resistance 54. The plate 35 has ears 40, 41, 42, 43 extending radially through slots in the ridge 11 of base 10, and bent down the sides of and under the base 10 where they hold a cover plate 44 in position. The usual threaded bush 27 is secured in a central aperture in base 10 and an inwardly extending lug 39 of the plate 35 is bent down into this aperture to contact with the bush. A cupshaped metal casing 63 is pressed over the base 10 and has ears 64, 65, 66, 67 extending over the ears 40, ... 43 of plate 35 so that the plate 35, plate 44, bush 27 and casing 63 are in metallic contact and readily dissipate heat generated in the resistance. A split ring 70 engaging a groove in the spindle 31, Fig. 4, and bearing against the bush 30 prevents axial movement of the spindle.

Title: Process for the treatment of hard waters
IPC: C02F5/02
Filed: 1933-02-10
Abstract: To obtain a purified feedwater free from soluble compounds, hard water is treated with phosphoric acid, either alone or together with barium compounds soluble in phosphoric acid, and subsequently with hydroxide of ammonium, hydroxide of calcium or magnesium also being used when there is much sulphate in the water.  For water containing both carbonate and sulphate, a quantity of barium salt equivalent to the sulphate is added to the phosphoric acid to precipitate the sulphate.  Excess of phosphoric acid is removed by means of limewater or magnesium hydroxide and the soluble phosphates formed are converted into insoluble phosphates on addition of ammonium hydroxide until an alkaline reaction is shown.  For water containing carbonate without sulphate, the equivalent quantity of phosphoric acid is added and then ammonia only.  The sludge obtained may be used for the recovery of phosphoric acid or as a fertilizer.

Abstract: 513,467. Alloys; heat-treatment. RENAULT, L. Feb. 12, 1938, No. 4463. Convention date, April 28, 1937. [Classes 72 and 82 (i)] Cylinders and cooling-jackets forged from a steel containing 0.85-1.25 per cent. of carbon and 1.5-2.4 per cent. of manganese (which may be partly-replaced by nickel or chromium in the proportion of two parts of nickel or chromium to one of manganese) are heated to obtain a homogeneous structure and softening of the metal, machined, heated to just above the Ac3 point to bring the metal into the austenitic state, quenched in a hardening bath at such a temperature that no transformation from the austenitic state takes place in the bath and finally cooled to effect the martensitic transformation. The above-referred to homogenizing treatment may consist of a heating for half-an-hour at 920‹C. followed by air-cooling and a reheating for half-an-hour at 790‹C. followed by slow cooling at 4‹C. per minute down to 550‹C. During machining a slight excess of material is left in the bore to permit rectification and final polishing after hardening : after machining the cylinder &c. is protected from decarburization by the use of an inert, reducing or carburizing atmosphere or by heating in a salt or lead bath or by coating with copper, aluminium or the substance known under the Registered Trade Mark " Bakelite." The hardening may consist of heating to 700‹C., then to 740-820‹C. and plunging in a bath of molten salt, e.g., the eutectic of sodium andpotassium nitrates at 300-400‹C. tongs to prevent distortion being used. The piece is then cooled in still air and tempered at 250‹C. for an hour. The cylinder is then cadmium-plated. The steel may also contain 0.1 or 0.15 per cent. of vanadium and up to 0.5 per cent. of molybdenum which may be wholly or partly replaced by three times the quantity of chromium or tungsten. According to the Specification as open to inspection under Sect. 91, the vanadium content may be wholly or partly replaced by titanium or aluminium.

Title: Improved steam traps
Inventor: GRAY BENJAMIN PHOENIX
IPC: F16T1/10
Filed: 1961-02-07
Abstract: 922,211. Valves. IMPERIAL CHEMICAL INDUSTRIES Ltd. Dec. 22, 1961, No. 4536/61. Class 135. [Also in Group XIII] A valve comprises a piston 13, valve stem 15, a conical valve end 16 e.g. of stainless steel, and a bellows 14 attached to the piston 13 at one end and a plug 11 at the other. When valve 16 is open, steam condensate from a spaceheating system (see Group XIII) flows through a condensate chamber 1 and causes a liquid (e.g mineral oil) to expand in element 9. The expanding liquid forces the valve to move towards its seating 5. The valve will remain in a constant position when the temperature of the expansible liquid is constant. The position of valve seating 5 with respect to the valve end 16 is adjustable by means of a threaded portion 28 of the condensate chamber 1 and lock-nut 30. The expansible liquid is also controlled by the external atmospheric temperature of the space being heated which affects the volume of liquid in an external vessel 21. The relative volumes of vessel 21 and the element 9 are such, that the heat input to the space being heated is varied by movement of the valve in response to changes in the external atmospheric temperature in order to maintain the space temperature constant. If the external atmospheric temperature continues to increase after the valve end 16 is fully closed, the pressure of the liquid exceeds the pressure required to compress spring 34, and the element 9, tubular connector 20 and vessel 21 move back from the valve end 16 thereby avoiding possible damage to the bellows 14.
