[Class 7 (iii)] Exhaust gases are used to inject heavy fuel into a partial combustion vaporizer. The gases are admitted through a nozzle 2 and induce heavy fuel from a float chamber 7. The vaporizer is heated initially by mixture from a spray carburetter, an air valve 19 being open and the charge being ignited by a sparking plug 16. The chamber 26 contains a cone 9 with air inlet passages 15, 10, grids 11 and balls 27, 28 of copper, iron, nickel, platinum, palladium or silver, which serves as a catalyst. The chambers 23, 26 are lined with refractory earth 21, 8, and an air space surrounds the chamber 26. The generated gas passes through an expansion chamber 14 into a cooling chamber 32 which contains rods 30 attached to a cover 29, the rods scraping the chamber when the cover is removed. The gas is drawn through the space between a cone 34 and a suctionactuated valve 37 into a chamber 50 where it is mixed with air drawn through a Venturi 40 from a passage 35 containing a valve 36. Further air may be admitted around the chamber 50 through a passage containing a suctionactuated valve 38. In the construction shown in Fig. 2, the fuel pipe 17 discharges directly into the nozzle 2 and the chamber 26 has a lining of copper and is surrounded by a jacket 54a to which exhaust gas is admitted tangentially through a pipe 55a. The jacket is surrounded by an annular space 57 containing heat insulating material. To indicate when the temperature of the chamber 26 is sufficiently high for the valve 19 to be closed contacts 60, 61 close a circuit to illuminate a lamp or move a pointer over a dial. After leaving the cooling chamber 32 the gas is admitted through nozzles 69 into a Venturi tube 67 where it is mixed with air which enters through a suctionactuated valve 75. The Venturi tube is provided with a handle 77 to facilitate its removal. The Specification as open to inspection under Sect. 91 states that air supplied by a rotary blower may induce the fuel. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to logical circuits
Inventor: NEWELL ALLEN FREDERICK
IPC: G06F7/38
Filed: 1957-02-08
Abstract: 824,791. Circuits employing bi-stable magnetic elements. MULLARD Ltd. Dec. 31, 1957 [Feb. 8, 1957], No. 4414/57. Class 40 (9). [Also in Group XIX] In a gating circuit as described in Specification 822,508 and comprising cores F1, F2 with rectangular hysteresis characteristics, the inhibiting action of transistor T2 on the pulse output circuit comprising transistor T1 is arranged to be effective only when two of the three input pulses A, B, C are applied simultaneously to input windings 11, 21. In the case of a single input pulse, the bias in winding 22 prevents reversal of the magnetic state of core F2 so that only core F1 changes over and produces an output pulse in a load O. The magnetic state of F2 is reversed, however, when more than one pulse A, B, C is applied simultaneously, but the resultant output of T2 in winding 13 is sufficient to prevent reversal of core F1 only when that core is energized by two of the pulses. The circuit shown functions as a binary adder, and includes a further core F3 which is biased so as to reverse its magnetic state and cause a transistor T3 to conduct only when two or three of the pulses A, B, C are applied simultaneously, the cores F1 and F3 providing the sum and carry outputs respectively.

Title: Improved process of manufacturing soluble phosphates
IPC: C05B11/14
Filed: 1921-11-10
Abstract: Mineral or precipitated calcium phosphate or bone ash suspended in a solution of ammonium sulphate is treated with sulphur dioxide.  The products are calcium sulphate and ammonium phosphate, together with ammonium sulphite in the case in which tri-calcium phosphate is treated.  The formation of sulphite can be avoided if one of the three molecules of sulphate required for the reaction is replaced by one of sulphuric acid.  No sulphite is formed when the initial material is precipitated calcium hydrogen phosphate, and in this case the sulphur dioxide can be recovered by heating the filtered reaction liquid.  Other acids readily volatile from hot solutions, such as acetic or formic acid, or carbon dioxide, or hydrogen sulphide may replace sulphur dioxide.  Reference has been directed by the Comptroller to Specification 26097/12.ALSO:Mineral or precipitated calcium phosphate or bone ash is mixed with a solution of sodium, potassium, or ammonium sulphate and the product treated with sulphur dioxide.

Title: Improvements in and relating to the extraction of protein from seeds
IPC: A23J1/14
Filed: 1946-02-19
Abstract: Seeds from which proteins are to be extracted are impregnated with dilute sulphuric, hydrochloric or phosphoric acid and heated to a temperature below the carbonisation temperature so as to concentrate the acid on the seeds; the latter are then washed until they are free from acid, whereafter the protein is extracted with an aqueous alkaline solution.  Clear stable protein solutions useful for spinning are obtained.  Oil-free seeds are preferably used, suitable seeds being castor-bean or other bean meal, nut meal and pea meal. The acid should preferably have an initial pH value not greater than 2, and the concentration of the acid may be effected at 40-70 DEG  C. A metallic bisulphate, e.g. sodium bisulphate, may be used instead of sulphuric acid, and instead of hydrochloric acid there may be used salts which yield it when heated with water, e.g. magnesium chloride. The extraction of protein from the acid-treated and washed seeds may be effected with a dilute alkaline solution in known manner, e.g. as described in Specification 575,402, and the solution may be used directly or treated to precipitate the protein, e.g. with dilute sulphuric acid or gaseous sulphur dioxide.  Examples of the process are given.  Specifications 534,728, 534,851 and U.S.A.  Specification 2,260,640 also are referred to.
