Title: Improvements in and relating to thermostatic control devices for furnaces
IPC: G05D23/02
Filed: 1926-09-04
Abstract: 275,431. Marks, E. C. R., (Williams Oil- O-Matic Heating Corporation). Sept. 4, 1926. Thermal switches : contacts. - A control device for a furnace comprises two concentric tubes 7, 9, projecting into the stack leading from the furnace, the differential expansion of the tubes controlling contacts in the circuit of a motor which actuates dampers or operates a liquid fuel burner. The natural draught of the furnaces causes a current of air to pass through the tube 7 from outside which increases the normal rate of contraction of both tubes when the furnace goes out. The tubes 7, 9 may be of iron and brass respectively and when heated, the relative expansion of the tube 9 raises a post 11 fixed to it which raises in turn a lever 20 pivoted at 21. The lever 20 carries a lava block 32 in frictional sliding engagement with a member 31 secured to a post 29 carrying the movable contact 19, and the members 32, 31, 29, 19 accordingly all move upwards, the contact 19 leaving the fixed contact 17, till the member 31 engages an adjustable fixed stop 25 after which the block 32 will slide over the member 31 and the latter together with the contact 19 will remain stationary. Immediately cooling sets in contact 19 will re-engage contact 17 and further cooling will only cause the block 32 to slide back again over the member 31.

Abstract: 680,873. Gasifying finely divided carbonaceous materials ; oil-gas generation. COMPAGNIE PAN-EUROPEENNE D'INSTALLATIONS ET D'EQUIPEMENT INDUSTRIELS. Sept. 6, 1950 [June 3, 1950], No. 21992/50. Classes 55 (i) and 55 (ii). Synthesis gases are obtained by gasifying finely divided oil, or coal &c. with steam and oxygen or air with or without oxygen, the gas generated being reheated with steam and a portion returned to the producer. Oil is injected through an outlet 1 into a producer 2 and gasifying agent through nozzles 3. Gases generated pass through a regenerator 7 and washer 10 in which steam is produced to a heated regenerator 5 and at 1200‹-1500‹C. return to the producer, part being discharged through a conduit 13 and regenerator 14 for use and the remainder issuing through a perforated partition 4 into the gasification zone. Supplementary oil, preferably of lighter character, may be injected through nozzles 19 ; a brick lining 20 at the outlet retains ungasified oil. At intervals the heat stored in regenerators 7, 14 is utilized by introducing air through conduits 21, 23 to burn off deposited carbon and heat up regenerator 5 to which heating oil or gas is admitted through an inlet 25 for combustion. The plant shown is duplicated to provide for gas making alternately in each of the two groups ; air for the gasifying agent may be supplied through conduit C from the air stream passing through the other group. In a modified producer, regenerators 7, 14, comprise lower and upper jackets round the gasification chamber. When ash-producing fuel is employed regenerator 7 is dispensed with, the sensible heat of the gas being used for boiler heating or coal drying &c. In a modification hydrocarbons such as methane may be transformed into a gas comprising substantially carbon monoxide and hydrogen.

BISBEE, and STOCKTON MADISON CORPORATION, [trading as CARANDO MACHINE WORKS]. June 7, 1962 [Nov. 24, 1961], No. 22107/62. Heading B3R. A machine for forming a cylinder from a bent metal sheet by welding the longitudinal overlapped edges thereof comprises means to hold the sheet edges in lapped relationship and to feed them to a pair of electrode wheels which engage opposite sides of the lap and press it together, and is characterized in that the electrode wheels are positively driven and mounted in such a way that they tend to draw the edges over one another as they are flattened Four pairs of pinch wheels 6, 7 are arranged above and below each edge of the sheet 5 and are inclined as seen in Fig. 3, to urge the two edges of the sheet into grooves in a Z-bar 2 which guides the sheet edges in lapped relationship to the pair of electrode wheels 20, 21 which are similarly inclined. There is thus no tendency for the lap to be forced apart during welding. The wheel inclinations are approximately 1¢ degrees. Welding pressure is derived from a pneumatic cylinder 25 and both electrode wheels are driven through shafts 31 and suitable gearing to friction wheels 27, 33, urged against the electrode wheel by pneumatic cylinders 32. This pressure is sufficient to substantially reduce the thickness of the lap. The lower four pinch wheels are urged upwardly through rods 16 by pneumatic cylinders 17. The pinch wheel peripheries are curved to conform to the inner and outer surfaces of the cylinder being formed.
