Abstract: 813,553. Hydraulic actuation of switches. GLOSTER AIRCRAFT CO. Ltd. Sept. 3,1957 [Sept. 3, 1956], No. 26877/56. Class 38 (5). A switch which is operated only when the difference between two hydraulic pressures is unequal to the difference between two other hydraulic pressures comprises a body 1 having two pistons 4, 4a. The piston 4 is acted on by hydraulic pressures fed via ports 2, 3 such that it pushes against a rod 4<SP>1</SP> which in turn engages a member 5 abutting a corresponding member 5a opposedly urged by piston 4a. Telescopic members 6, 6a, held apart by a spring 8, carry contacts 7, 7a wired to connector pins 9, 9a. Should the differential pressure on piston 4 exceed that on piston 4a, for example, the piston 4a is pushed to the left and a flange on member 5 bears against member 6 to compress spring 8 and bring contacts 7, 7a into engagement.

Patent GB-750083-A (GB)
Title: Improvements relating to the refining of petroleum hydrocarbons
IPC: C10G19/04
Filed: 1952-10-28
Abstract: Gasoline obtained by the catalytic cracking of petroleum distillates boiling above 300 DEG C. is refined by separating the cracked gasoline into a light gasoline, and a heavy gasoline containing the thiophenols and alkyl phenols; sweetening the heavy gasoline with caustic alkali solution in the absence of air; treating the alkali extract with free oxygen to oxidize thiophenols; sweetening the light gasoline with this oxidized alkali extract in the absence of air; and treating the alkali with free oxygen to oxidize mercaptans.  The disulphides formed in oxidizing the thiophenols and mercaptans are separated from the alkali solutions and the alkali solutiouns treated with a hydrocarbon solvent such as kerosine or isopentane to remove remaining disulphides; no catalyst is necessary in these oxidation reactions.  The process may be operated continuously. An example is given of the treatment of a light gasoline boiling up to 150 DEG C. and a heavy gasoline boiling between 150 and 220 DEG C.; these gasolines are produced by cracking a mass distillate of boiling range 300-550 DEG C. over a silica-alumina catalyst.  The sweetened light and heavy gasolines may be combined and an antioxidant, e.g. paraphenylene-diamine, and a metal deactivator may be added thereto.

Class 51 (2) [Also in Group II] In a continuously operated heat treatment furnace 10 having a roller-hearth 14 and heated by electric resistances 15 which may also be provided in the floor and/or roof and are controlled by one or more thermocouples, a stabilized hot gaseous atmosphere containing CO 2 , CO, H 2 O and H 2  in which the H 2 O/H 2  ratio is scaling to steel, is produced by burning an air/gas mixture externally of the furnace, controlling the CO,/CO ratio by the temperature of combustion and the air/gas ratio, and neutralizing the scaling property of the H 2 O by adding the vapour of a lithium compound to the said atmosphere. Two gas generators 18 having outlet ducts 25 into the furnace, mingle their combustion gases with lithiated gases from adjacent outlets 52 connected to lithium vapour generators 19, and the partially opened furnace doors 11 and 12 provide atmosphere vents and continuous access for the work, e.g. steel bars. Each gas generator 18, Fig. 2, comprises a cylindrical shell with a porous refractory lining 21 defining a combustion chamber 22, short flame burners 23 in tangentially disposed burner blocks adjacent the top of the chamber, and an air-cooled induction tube 42 supplying raw hydrocarbons into the duct 25 near a spiral insert 44 when it is necessary to decrease the CO 2 /CO ratio to produce a carburizing atmosphere. Each lithium vapour generator comprises a tangential burner 51 at one end, a cylindrical combustion chamber 49 discharging gases through an opening 53 into an alloy tube 52 and over a boat 56 filled with a fused cake of lithium compounds, preferably a mixture of lithium carburate 60 per cent and lithium chloride 40 per cent. Additional raw gas supplying tubes 42<SP>1</SP> may feed directly into the furnace if a highly carburizing atmosphere is required. Air and gas supplied through pipes 36 and 37 respectively are supplied to the atmosphere generators 18 through regulators 38 in the gas line and venturi mixing tubes 39, to the lithium vapour generators 19 through venturi tubes 63 and thermostatically controlled valves 61, and to the induction tubes 42, 42<SP>1</SP> through valves as at 43.

Title: Improvements in or relating to the manufacture of thermostats

Abstract: 408,014. Thermostats. ROYER, G. G., 7, Impasse de St.-Ouen, Paris. Oct. 5, 1932, No. 27687. Convention date, Oct. 5, 1931. [Class 64 (ii).] In the manufacture of a thermostat employing an expansible fluid in a rigid container, or in a flexible bellows, which is sealed by a closing pin, the container is filled to the upper opening of the hole for the closing pin at a temperature close to that at which the thermostat is intended to act, the difference in temperature depending on the volume of the closing pin. A container 2 is provided with an actuating piston 3, and with a stopper 8 for the pin 11. After the expansible substance is introduced, it may be heated to the required temperature to expel excess and the pin then inserted, or the temperature may be lowered to the required degree from a higher point while adding some of the fluid by means of a container above the thermostat. In either case, the piston 3 commences to move only at the required temperature, when the thermostat is subsequently in use. The use of an adjusting screw is thereby obviated. The head 13 may be forced by the spring 6 against the plug 8. In an alternative method, the thermostat may first be evacuated and the fluid then introduced under atmospheric or higher pressure while cooling to a temperature slightly below that required, the subsequent operations being as described above ; air bubbles are thereby eliminated. A bellows thermostat may be filled in a similar manner. The expansible substance may be a molten solid.
