Filed: 1947-06-16
Abstract: 637,458. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. June 16, 1947, No. 15815. Convention date, June 15, 1946. [Class 38 (v)] The temperature of a thermostatically - controlled electric iron is adjustable by an arm 99 extending through a slot 100 in the handle 25 and co-operating with a plate 104 projecting beyond the slot, the plate having marks on its periphery corresponding to the materials to be ironed, together with an "off" mark. The thermostatic bimetal bar 46, consisting of two reversed sections, is secured to the underside of the bight of a U-shape base-plate 43 by rivets 49, 50, the rivet 49 also securing a heat-conducting aluminium block 47. The base-plate 43 is fixed to the sole-plate 10 at the bight by screws 43a, the arrangement permitting the thermostat being calibrated before it is mounted in the iron. Rearwardly extending legs of the base-plate 43 have upright walls 44 connected at the rear enc by a transverse section 54 which carries spring contact arms 53, 55 having contacts 51, 52 respec tively. The relatively strong arm 53 is biassed upwardly against an insulating adjustable stop 56a and the weaker arm 53 is biassed downwardly against an insulating actuator 57 mounted on the bimetal strip 46 and is protected against heating by a shunting strip 59. The stop 56a is mounted in a screw 60 in the end of a lever 61 pivoted on the walls 44 by a spindle 63, the forward end of lever 61 engaging a cam 87. The cam 87 is rotatable on an extension 83 of the base-plate 43 and has a U-shape spring 90 provided on the lower limb with an aperture which is snapped over an extrusion 92 on the extension 83 and holds the cam 87 against the upper side of the extension, the cam 87 being rotatable by a keyed shaft 93 operated by the arm 99. When the arm 99 is against the " off " mark, an abrupt rise 105a on the cam 87 pivots the lever 61 so that the stop 56a moves the arm 53 downwards to separate the contacts 51, 52 and the arm 55 comes to rest against the actuator 57. In other positions of the arm 99, the inclined cam 87 permits the contacts 51, 52 to engage, with varying amounts of separation between arm 55 and the actuator 57, until the contact 52 is moved away by the latter. Terminals 65, 66 on the arms 53, 55 are connected in series with a sheathed wire heating element 13, 14 cast in a ridge 18 in the soleplate 10. A neon lamp 111 mounted on the terminal 66 is viewed through a window in the handle 25 and is in shunt with the contacts 51, 52 so as to be illuminated when the iron has attained its desired temperature. Specification 637,457, [Group VIII], is referred to.

Title: Apparatus for the analysis of gases
IPC: G01N7/02
Filed: 1962-04-27
Abstract: 982,038. Gas analysis. K. LADENDORF, E. LADENDORF, W. LADENDORF, E. LADENDORF, P. LADENDORF, and K. F. LADENDORF, [trading as BRAN & LUBBE]. April 27, 1962 [June 10, 1961], No. 16078/62. Heading G1B. In an apparatus for the analysis of a gaseous mixture by treating it with a liquid which reacts with one or more components of the gaseous mixture with an accompanying colour-change of the liquid, a stream of the gaseous mixture at constant pressure is mixed with a predetermined volume of the liquid at predetermined intervals of time. The gaseous mixture enters the apparatus via pipe 10, which is connected with a dip tube 12 immersed in oil contained in bottle 11, the level of the oil in bottle 11 being regulated within fine limits by the extension or contraction of the oilfilled bellows 14 using a hand wheel 15 connected to the bellows via a worm drive 16. The gaseous mixture passes into coil 20 via three way valve 17, and capillary tube 18, the pressure drop across the capillary tube being measured by pressure gauge 19. Valve 30 is rotated either continuously or intermittently by a motor 34. The liquid reagent is supplied to valve 30 from storage vessel 27 via pipe 25, colour test cell 23 and pipe 26. As valve 30 rotates, the bore 33 is alternately filled with liquid reagent and then emptied via pipe 36 into coil 20 by the pressure of the gaseous mixture from line 35. The mixture of gas and liquid flows out of coil 20 into test cell 22 where the two phases separate, both the gas and the liquid reagent overflowing from the cell via line 21. The colour of the liquid reagent in cell 22 is compared with that of the liquid flowing through cell 23, using the photo-electric cells 44 and 45. The pressure above the liquid in vessel 27 is automatically adjusted by connecting the top of the vessel to gas inlet-pipe 10 by pipe 40 and a column 41 for removing the reactive component(s) of the gas. The outer surface of the dip tube 12 is formed with sawtooth corrugations to break up the large gas bubbles from tube 12 ascending through the oil in bottle 11. The valve 30 may be made of polytetrafluorethylene. An embodiment is described wherein the rotary valve member is formed with a recess to act as a liquid reagent measuring chamber in place of the bore 33.
