Title: Pump for injecting fuel
IPC: F02M59/04
Filed: 1948-01-21
Abstract: 648,459. Fuel-injection pumps. BISCHOF, B. Jan. 21, 1948, No. 1852. Convention date, Jan. 22, 1947. [Class 102(i)] [Also in Group XXIX] In a fuel-injection pump, a number of cylinders are arranged around the driving shaft 1 and the pistons 9 are reciprocated by a cam 3. Each piston 9 has an edge 18 that first closes the fuel inlet 12 and after the piston has moved further upwards, an outlet-port 13 is uncovered by an edge 19 connected to the pumping chamber 60. Each cylinder is fitted with a secondary piston 21 loaded by a spring 22 and entering chamber 24 filled with liquid and having a port 29 the opening of which is controlled by valve surfaces on the piston 30 and a control member 53. Injection takes place when escape from the port 29 is prevented so that the piston 21 is locked. The member 30 has a recess 38 bounded by sealing edges and a port 40 passes through the member 30 into the recess 38. The edge 36 first closes the port 29 and it remains closed, until an edge 57 on the control member 53 uncovers the port 40. There are as many edges 57 as there are pump cylinders and each edge 36, 57 is inclined so that the beginning and end of injection can be varied. The member 30 can be moved axially by a speed governor (see Group XXIX).

Title: Dual fluid supply changeover control
IPC: F02C9/40
Filed: 1969-01-13
Abstract: 1,213,443. Automatic speed control. UNITED AIRCRAFT CORP. Jan.13, 1969 [March 8, 1968], No.1862/69. Heading G3R. [Also in Divisions F1 and F2] In a dual-fuel gas turbine, during transfer from one source to the other the valves controlling flow from the sources to respective combustion chamber manifolds are respectively closed and opened over the same period and ideally at the same speed to ensure smooth transfer. As shown, valves 14, 24 are respectively open and closed, and flow from source 10 through valve 14 is modulated according to signals from control 96 which senses engine speed and temperature parameters and supplies signals through summer 50 to motor 30. Totransfer to source 20, relay 62 is energized to reposition its moving contacts 64, 74, 92. Motor 30 will normally be stationary at this time so that the signal from potentiometer 34 will differentiate to zero at 54 so that summer 66 will only receive a signal from potentiometer 70 which is amplified at 68 and via 78 determines the rate of closure of valve 14 by motor 30. The feedback through 34, 54 ensures controlled movement of motor 30. The signal from 34 is also differentiated at 48 and applies a constant voltage input to summer 50 the output of which is applied via 88 to motor 32 which provides a feedback to summer 50 via potentiometer 36 and differentiator 46 such that the speed of opening of valve 24 matches the speed of closure of valve 14 except for such variations as may be dictated by signals to summer 50 from control 96. Either source may be gas or liquid. Valve 24 may be of the butterfly type.

Patent GB-745145-A (GB)
Title: Improvements in or relating to lubricating grease compositions
IPC: B65B43/26
Filed: 1953-01-23
Abstract: Lubricating grease compositions are prepared by admixing with a lubricating oil a complex soap as defined below, heating the mixture to dissolve the soap, cooling the heated mixture until the soap crystallizes and a grease structure is formed, and then thickening the cooled mixture by the application of a rate of shear in excess of 10,000 reciprocal seconds without concurrent mixing.  After the cooling step and before the thickening step, additional lubricating oil may be added to the cooled mixture, but this additional lubricating oil must have a viscosity index less than 75 unless the rate of cooling has been greater than that corresponding to atmospheric cooling.  The complex soap is defined as a soap of rapeseed oil or a mixture of soaps containing more than 8 carbon atoms in the molcule and monocarboxylate salts (e.g. acetates, furoates and acrylates) containing less than 8 carbon atoms in the molecule.  The lubricating oil may be mineral oil but, where additional lubricating oil is added as mentioned above, this additional oil may be a synthetic lubricating oil Synthetic oils mentioned are polymerized silicone oils, long-chain formals, organic carbonates, polymerized olefins, esters and copolymers of aliphatic and aromatic compounds.  Ester lubricating oils mentioned are esters of mono- or poly-basic acids, esters of glycols, of polymerized glycols or of glycol ethers, complex esters such as monohydric alcoholdibasic acid-glycol esters or monohydric alcohol-dibasic acid-glycol-monobasic acid esters, or blends of esters.  The complex soap may be formed in situ in the lubricating oil.  The high rates of shear may be produced in a Gaulin homogenizer, a rolling mill, a Morehouse mill or a pressure viscosimeter.  In the examples, lubricating greases are prepared according to the process of the invention from mineral lubricating oil and sodium soap of rapeseed oil, with or without phenyl alpha-naphthylamine. N, N1-disalicylidene-1, 2-diaminopropane and sodium mahogany sulphonate, and in some cases additional synthetic lubricating oil is incorporated; the synthetic lubricating oils employed are (a) a blend of di-2-ethylhexyl sebacate and a complex ester obtained by reacting 2 mols of the 2-ethylhexyl half ester of adipic acid with 1 mol of a polyethylene glycol, (b) a phenyl silicone fluid, and (c) a formal of C8 oxo alcohol.  In further examples, lubricating greases are prepared according to the process of the invention from (i) mineral lubricating oil, lithium hydroxide, hydrogenated fish oil fatty acids, acetic acid and phenyl alpha-naphthylamine and (ii) mineral lubricating oil, sodium hydroxide, hydrogenated fish oil fatty acids, furfural (which reacts with the sodium hydroxide according to the Cavvizarro reaction to form sodium furoate), and phenyl alpha-naphthylamine.  Some of the greases of the examples contain free alkali.

Title: Improvements in and relating to thermionic valve transmitting sets for wireless telegraphy and telephony
IPC: H03H7/38
Filed: 1922-01-24
Abstract: 194,864. Preston, L. G., and Shearing, G. Jan. 24, 1922. Thermionic oscillation generators and modulating systems.- Relates to the grid coupling- coils of transmitting-valves, particularly in highpowered sets. When the grid coil of an oscillation-genera.tor is coupled to the aerial, or when the grid coil of a power valve is coupled to a separate exciting-valve, as shown in Fig. 2, either sparking trouble or else@an irregularity in output is liable to occur when, in order to shorten the wave length, a portion b, c of the coil is cut out. These effects arise according as the redundant portion is left on open-circuit or is short-circuited. In order to avoid this difficulty, the grid coil, whether of disc form, Fig. 1, or cylindrical, Fig. 4, is split up into several sections 1 - - 4, arranged in equal numbers on each side of the exciting coil c, thereby reducing the mutual coupling between the pcrtions 1 - - 4, and the sparking potentials to earth of the corresponding tapping-points a - - f. An inductance 5 may be inserted to reduce the current flowing in the short-circuited portion, and signalling may be effected by varying the value of this inductance by means of a key. As shown in Fig. 1, the adjacent coils are cf different diameters in order further to reduce the danger of sparking on to the connecting leads.

Title: Improved regeneration and activation of supported platinum catalysts as used in hydrocarbon conversion processes
IPC: B01J23/96
Filed: 1961-01-20
Abstract: In a hydrocarbon conversion process in which a hydrocarbon is converted by contact with a bed of Pt-Al2O3-Cl2 catalyst, the spent catalyst is periodically regenerated by being freed of carbonaceous deposits by burning, activated with a hydrogen-containing gas and oxides are removed from the catalyst by contact with the hydrogen-containing gas the catalyst thereafter being dried with a drying gas until the water vapour partial pressure in the drying gas after contact with the regenerated catalyst is less than 1,2 mm. Hg. absolute, before the dried catalyst is contacted with hydrocarbon feedstock.  Preferably the catalyst is burnt until its carbon content is less than 0,1%.  Removal of carbon by burning results in agglomeration of Pt to crystals greater than 70  in size.  Activation of the catalyst with chlorine however causes redispersion of platinum.  Chlorine activation is effected until free chlorine is detected in gases emerging from the catalyst bed. An excess of chlorine is preferably left in contact with the catalyst bed, the latter thereafter being subjected to reduction, e.g. by contact with gradually increasing amounts of hydrogen at 800 DEG -1050 DEG F. After reduction the catalyst may be dried at 800 DEG -1050 DEG F. for 4 hours.  An example is given.
