Title: Rotary-piston internal combustion engine
IPC: F02B75/02
Filed: 1971-04-02
Abstract: 1367901 Rotary positive displacement machines G J KNEE 29 March 1972 [2 April 1971] 8566/71 Heading F1F An internal combustion engine comprises a rotor 1 eccentrically mounted on a drive shaft 5 in a casing 2 having a substantially circular inner profile. Inlet and outlet ports 12, 13 controlled by valves 14 are positioned so as to be adjacent apex seals 20 when the rotor is in a position where the two chambers 9, 10 have minimum and maximum volumes respectively. Starting from a position in which the seals 20 cover ports 12, 13 the rotor 1 rotates clockwise drawing in gas through the port 12 into chamber 9 for 180 degrees of rotor rotation as chamber 10 exhausts the products of combustion through the port 13 which closes at the end of the first 180 degrees rotor rotation. The second 180 degrees rotor rotation produces induction of gas through port 12 into chamber 10 and compression of gas in chamber 9. The port 12 is then closed. The third 180 degrees rotor rotation is effected by combustion of gases in chamber 9 while chamber 10 is compressed. The port 13 opens so that the last 180 degrees rotor rotation results in combustion in chamber 10 accompanied by exhaust of products of combustion through port 13 from chamber 9. Alternative embodiments are also described where, instead of the inlet and outlet being in the cylindrical wall, the inlet of fluid takes places through ducts in the drive shaft and cavities in the rotor Fig. 5 (not shown) on the inlet and outlet are provided in the side walls of the casing Fig. 6 (not shown).
Patent GB-829105-A (GB)
Title: A combined process for distilling and cracking hydrocarbon oils
IPC: B01J10/00
Filed: 1956-03-19
Abstract: <PICT:0829105/III/1> In a process for the thermal cracking of mineral oils wherein the oil is mixed with superheated steam having a temperature of 800 DEG  to 1500 DEG  C. in a cyclone chamber, the hot mixture of cracked gases and vapours, together with steam, leaving the cyclone chamber is cooled by utilizing it to distil hydrocarbon oil by direct contact, and/or to superheat steam by indirect heat exchange.  The vapours and gases discharged from the distillation zone are subjected to fractionation whereby benzine, diesel oil and gas oil fractions are obtained.  The process may also be used for the production of gaseous olefins.  The higher boiling fractions of the product may be used as feed for the cracking stage.  The distillation may be carried out in a cyclone chamber, the oil being distributed as a thin layer on the inner surface.  The mixture of gases, vapours and steam leaves the cracking chamber at about 500-900 DEG  C.; and the quantity of oil which is added for distillation is so chosen that the temperature in the distilling-chamber is such, e.g. between 200 DEG and 600 DEG  C., that the distillation-residue (fuel oil or bitumen) can be discharged from the apparatus as a freely-flowing liquid.  The superheated steam for the cracking stage may be obtained in part by the reaction of hydrogen and oxygen; and secondary steam, derived from the process, is added to control the temperature of the steam which enters the cracking chamber.  Hydrogen and oxygen, supplied through conduits 11 and 12, respectively, are burned in the apex of cyclone burner 1; and secondary superheated steam is introduced, through conduit 13, tangentially into the end of the burner. Superheated steam at the desired temperature is conducted to the apex of cracking cyclone 2; and the hydrocarbon oil-to-be-cracked is introduced through conduit 14.  Hydrocarbon oil is sprayed through conduit 15 into the mixture of gases, vapour and steam leaving cyclone 2; and the mixture enters the first of a series of chambers 3, 4, 5 and 6.  These chambers each have a jacket; and steam, supplied through valve 37, is passed through the jackets in the order 6, 5, 4, 3.  By these means a temperature of about 600 DEG  C. is maintained in chamber 3; but the temperature falls progressively through the series of chambers, reaching about 250 DEG  C. at the outlet of chamber 6.  Fractions such as benzine, diesel oil and lubricating oil are collected in receivers 8, 9, 10.  The heat of condensation of the steam separated from the gases, discharged from outlet 22, can be utilized to operate an absorption refrigerator plant for producing the low-temperature necessary for the gas-separation.  The superheated steam leaving the jacket of chamber 3 is introduced through conduit 13 into burner 1.  One of the last chambers may, if desired, be operated as an evaporator for water. Specification 825,841 is referred to.

Patent GB-609689-A (GB)
Title: A process of manufacturing ferrous bodies containing silicon
IPC: C22C33/02
Filed: 1946-03-20
Abstract: Shaped ferrous bodies more particularly for electrical purposes, are made by intimately admixing ferrous powder with up to 6 per cent silicon powder, compacting the mixture and sintering the compact, at a temperature within the austenitic range of the ferrous component, until silicon is diffused into the ferrous component.  This diffusion is effected by either removing from the compact traces of oxygen intially contained therein by the addition of solid deoxidizers such as powdery aluminium, titanium, magnesium, molybdenum and carbon preferably in the form of graphite, or by the use of pure electrolytic iron powder and reduced silicon powder, care being taken to prevent oxidation during handling.  The sintering in both methods is carried out in a protective atmosphere, such as dessicated hydrogen, lithium, or the like.  In a preferred process according to the former method, a compact of commercial iron powder, up to 3 per cent silicon and the required quantity of solid deoxidizer to bind the oxygen, for example 0.7 per cent graphite, shaped under a pressure of 30-40 tons per sq. in. is sintered at about 1100 DEG C. for 1-2 1/2 hrs. in a protective atmosphere.  In a modification carbon or graphite is used as a deoxider in an amount considerably exceeding that required for combining with the oxygen, and excess left after diffusion of the silicon is either removed by a second sintering step in a decarburizing atmosphere such as hydrogen, carbon monoxide or a mixture of both, or retained in the body.  In this latter event a similar two-step sintering process may be used and the second sintering step carried out in a protective atmosphere. Silicon in excess of that required to be diffused into the iron may also be used as a deoxidizer.  Then if a compact shaped from a mix containing about 4 per cent silicon powder is sintered in a protective atmosphere at about 1000 DEG C. to 1200 DEG C., up to 3 per cent silicon is diffused into the iron.  In a further modified process deoxidation may be effected by sintering a compact containing up to 6 per cent silicon in a deoxidizing atmosphere such as dessicated hydrogen for from 6 to 18 hrs. at about 1000 DEG C. to 1200 DEG C.  Powder ferro-silicon may be substituted for the silicon powder and a portion of the iron powder, in any of the foregoing processes.
