Title: Improvements in or relating to electric temperature regulators having signalling devices
IPC: H01H35/26
Filed: 1946-10-18
Abstract: 618,092. Thermal switches. APPELBERG, C., (trading as BIRKA REGULATOR, C. APPELBERG). Oct. 18, 1946, No. 31036. Convention date, Oct. 20, 1945. [Class 38 (v)] A temperature regulator for electric heating apparatus has additional contacts controlled by the thermal element for indicating excessive departures from the mean temperature to which the regulator is set. A bellows 20 acts on a spring-controlled plate 2 pivoted on a spring-controlled plate 2 pivoted on a spindle 1 by means of lugs 11 and carrying contacts cooperating with contact-carrying arms 3 ... 5 also mounted by means of lugs on the spindle 1 and controlling, respectively, the circuit to regulating apparatus 18 and signal relays (not shown). The arms 3, 4, are above, and the arm 5 is bent round so as to lie below, the plate 2. For operating-temperature adjustment, a screw 24 co-operates with a U-shaped lever 30 pivoted on the spindle 1 and controlled by a spring 33. In order to maintain a constant temperature difference for the signal contactarms 4, 5, a spring 34 and stud 35 press the arm 3 against lever 30, and a screw 39 engaging the lever 30 bears on the top of arm 5 against the action of a spring which pushes the arm upwards. Normal control of the temperature is effected by the contacts on the plate 2 and arm 3, but, in the event of an excessive rise or fall in temperature, the plate 2 rises to engage the arm 4, or falls to engage the arm 5, to give a signal. Figs. 10, 11 show a further arrangement for simultaneous adjustment of the arms, the arm 5 being superposed over arm 4 and pivoted at 40 to a bracket 41 fixed to the plate 2, which is urged by a spring 23 against the thermal element. The plate 2 carries a screw 43 passing freely through the arm 4 and having a nut 44 on which the arm 5 bears by means of a spring 42. A screw 49 on the arm 4 is urged by the spring 42 against the adjustment lever which is pivoted at 45 and biassed by a spring 33 against the screw 24, a spring 34 urging the lever 3 downwards so that a stud 48 thereon bears on the adjustment lever. In a simpler form, the lever 30 is dispensed with and separate screws provided for adjusting arms 3 ... 5 independently of one another, Figs. 1-4 (not shown).

Title: Automatic ignition installation for gas stoves
IPC: F24C3/10
Filed: 1928-10-26
Abstract: 299,470. Jeanneret, B. H. Oct. 28, 1927, [Convention date]. Lighting burners by electric and frictional devices.-Gas stove burners are lit by sparkproducing means normally positioned at a distance from the burner, and actuated by means comprising a pawl mounted on a rotating part of the gas valve and co-operating with a slidably mounted rod. Fig. 2 shows an electric ignition device, comprising electrodes 4, 5 carried by arms 6, 7 of insulating material pivoted on shafts 8, 9 mounted on a sleeve 20 secured to the gas pipe. The arms are provided with gears in order that they may move simultaneously. The electrode 4 is in electrical connection with the shaft 8 through a conductor 13 and spring-pressed plunger 14, and the electrode 5 is similarly connected to the shaft 9, the two shafts being connected to a source of supply at, for example, 125 to 200 volts. The electrodes are normally covered by sliding insulating sleeves 17, pressed forwardly by springs. On opening the gas valve a pawl 1 carried by it moves a rod 22, which, engaging the arm 7, causes the arms to move to bring the electrodes into contact, the sleeves 17 being pressed back. Further movement of the tap causes the pawl 1 to disengage the rod 22, and the arms 6, 7 fly apart under the action of a spring 19, causing a spark at the electrodes'. The pawl 1 is then maintained by the rod 22 in the inoperative position shown in dotted lines, so that the valve may be further adjusted without affecting the ignition mechanism. Fig. 5 shows a frictional ignition means, in which a rod 30, operated from the gas valve in the manner previously described in connection with the rod 22, moves a pivoted arm 24 carrying the friction igniter 25, 26. On the forward movement, the wheel 25 is not turned, the teeth slipping over the teeth of a pivoted sector 31. On the rapid return movement of the arm 24, caused by a spring 28 when the pawl 1 disengages the rod 30, the teeth on the wheel and the sector engage, causing the friction wheel to rotate and produce the spark.

Patent GB-762728-A (GB)
Title: Platinum-alumina catalyst containing added aluminum chloride
IPC: B01J27/13
Filed: 1954-10-29
Abstract: Alumina-supported platinum catalysts are prepared by contacting alumina with an aqueous solution containing both aluminium chloride and an inorganic platinum-containing compound, and drying and reducing the product.  The final catalyst preferably contains by weight 0.01-2 per cent of platinum and 0.1-15 per cent of aluminium chloride.  Alumina derived from precipitated alumina trihydrate or monohydrate, or from aluminium chloride or acetate, may be used; it may be given a preliminary drying at 250 DEG -650 DEG F. for 2-24 hours.  Minor amounts of silica. boria, or P2O5 may be present. Suitable platinum-containing compounds are chloroplatinic acid, platinum disulphide, ammonium chloroplatinate, and dinitrito-diammino-platinum.  In examples, dried alumina is mixed to a paste with an aqueous solution of chloroplatinic acid and aluminium chloride.  An alternative method of preparation is to add ammonia to mixed solutions of aluminium chloride and chloroplatinic acid in an amount insufficient to convert all the aluminium chloride to alumina. Reduction is effected by hydrogenation, calcination, or treatment with hydrazine or its salts.  The catalyst is especially suitable for the hydroforming of naphthas, but is also useful for hydrogenation, hydrocracking, cracking and oxidation reactions.
