Title: Improvements relating to anodising beryllium
Inventor: COTTON JOSEPH BERNARD
IPC: C25D11/34
Filed: 1967-03-22
Abstract: 1,222,653. Anodizing beryllium. IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd. March 13, 1968 [March 22, 1967 (2)], No. 13491/67. Heading C7B. Beryllium is provided with a coating protecting it from corrosion by anodizing in an aqueous bath containing at least 10g/1 of a sodium borate or phosphate. The anodizing bath may be a saturated solution but preferably contains 100g/1 of the sodium borate or phosphate which may be borax, or crystalline sodium metaborate or monosodium orthophosphate. The anodizing voltage may be raised up to about 100 volts while maintaining a current density of 50mA/sq. cm. and the voltage is then maintained at this maximum value while the current decays, a typical total anodizing time being 20 minutes and producing an oxide coating of 1500 A thickness. Prior to anodizing, the beryllium may be cleaned by immersion in an aqueous solution of sodium metasilicate, sodium carbonate and a wetting agent at 60 to 80‹ C. or by cathodic cleaning in aqueous KOH at a temperature of up to 48‹ C., and then rinsed in demineralized water. Reference has been directed by the Comptroller to Specification 1,078,165.

Patent GB-686914-A (GB)
Title: Two-stroke cycle engine
Inventor: ROSEN CARL GEORGE ARTHUR
IPC: F02B25/00
Filed: 1950-05-31
Abstract: 686,914. Cylinder construction; fuel injection; valves and valve gear. CATERPILLAR TRACTOR CO. May 31, 1950, No. 13570/50. Classes 7 (ii), 7 (iii) and 7 (vi). In a two-stroke engine having a cylinder with intake and exhaust ports in the wall thereof controlled by a sliding valve sleeve which remains stationary over part of the engine cycle, auxiliary valve means delay the admission of intake air until the cylinder working pressure is less than that of the said air. As shown applied to an in-line multi-cylinder two-stroke diesel engine having in each cylinder 11, Fig. 1, inlet ports 34<SP>1</SP>, 43<SP>1</SP>, and exhaust ports 37', Figs. 6 and 7, controlled by a sleeve valve 56 axially reciprocable between the cylinder and a junkhead 15 formed with a deflector 26 to promote loop scavenging, air is supplied by a blower (not shown) to a chamber 33 communicating with the ports 34' in each cylinder via passages 34 and with the ports 43' in each cylinder via rotary valves 48 on a single valve shaft 46 carrying also cams operating fuel injector pumps (not shown) supplying injectors 28 delivering to precombustion chambers 30. The junkheads are secured to a head member 16 common to all the cylinders, which are provided with liners 12 secured by bolted-on end rings 13. The ports 43<SP>1</SP> extend further down the cylinders than the ports 37<SP>1</SP>, 34<SP>1</SP>, but are closed off from the chamber 33 by the valves 48, when the valves 56 are moving upward, until the ports 34' begin to open, thus eliminating blow-back into the chamber 33. When the valves 56 are moving downwardly, the valves 48 are open and supercharging is effected through the ports 43' after the ports 37' close. Due to the progressive closing of the ports by the valves 56, the effect of the deflector 26 on the scavenging air stream gradually diminishes so that the initial loop scavenging changes to a final direct flow between the respective ports. The valves 48 are driven from the engine crankshaft through spur gearing 47, bevel gears further transmitting the drive to gears 76 which mesh respective upper and lower toothed sleeves 71, 68 on one end cylinder, these sleeves entraining corresponding sleeves on the adjacent cylinder and so on throughout the cylinder line. The facing ends of the sleeves 71, 68 of each cylinder are formed as complementary cam surfaces 66, 67, Fig. 3, positively actuating the corresponding valve 56 through paired rollers 62, 63 mounted thereon and each engaging the other and a respective cam surface. Further rollers 78 co-act with hardened faces 82 of axial channel members 80 to prevent rotation of the valve 56. A dwell 83 on the cam surfaces 66, 67 extends the period when only the exhaust ports 37<SP>1</SP> are open, and an extended flat portion 77 of the surfaces is provided to retain the valve 56 in its lowermost position during the high-pressure part of the engine cycle, the valve being thin enough for the gas pressure to seal it against the ports over this part of the cycle.

Abstract: 603,165. Centrifugal fans. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and VOYSEY, R. B. May 31, 1945, No. 13743. [Class 110 (i)] An impeller is constructed having substantially radially extending vanes each rigidly connected along one edge to a mass comprising hub and disc and adapted to transmit into said disc without substantial change in magnitude or relative change in phase, vibration exciting impulses externally applied to the vanes, whereby-at any given instant the effect on the disc of-any one group of external regularly applied and equal vibration-exciting impulses acting for example on the tips of the vanes is wholly or partly counterbalanced by the combined effect of the other impulses on said disc. One method of carrying this into effect is described and consists in making the root thickness of each vane 2 at its outlet edge 6 at least 75 per cent of the root thickness of the typical vane section, which section lies in a normal plane through the blade tip Y, said plane making an angle with a transverse plane of substantially 55 degrees. By a suitable choice of the number of impeller and diffuser vanes the vector resultant of the impulses transmitted from the impeller blades to the disc can be made to approximate to zero. A method of determining the resonant frequency of impeller vanes is also described.

Abstract: 696,643. Electric indicating systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION June 5, 1951 [June 5, 1950], No. 14012/50. Class 40 (i) [Also in Group XXXVII] Apparatus for remotely indicating the reading of a measuring instrument having an angularly movable indicating member comprises a transmitter having a rotating contact arm which periodically (e.g.) once per revolution) contacts the indicating member to complete an electric circuit comprising a condenser (normally charged through a series resistance from a positive source) whereby the condenser is momentarily discharged through a stylus carried by an arm at the receiver, which may be rotated in synchronism with the transmitter contact arm, to mark a constant speed recording paper tape. Alternatively plural rotary datum or measurement transmitters may control the discharge of separate condenser circuits through corresponding fixed parallel styli to mark a constant speed paper tape as above. In Fig. 2, arm 3 having flexible contact 5 is rotated by synchronous motor 1 energized from an A.C. source to momentarily contact pointer 7 of instrument 2 measuring e.g. mechanical strain or displacement. The momentary circuit completion discharges condenser 20 through backing plate 19, the moving sensitized paper 18, and one arm of the tripartite stylus rotor 15 which is rotated through 3 : 1 gearing by synchronous motor 8, the resultant successive traces recording successive angular deflections of pointer 7. A datum transmitter may record a reference trace. Plural transmitters 23, 24 (Fig 3) having synchronous feeler arms contacting their measuring pointers may discharge multiple condensers 29, 30 through corresponding' fixed parallel styli 25, 26 to mark a recording paper tape 27 traversed at constant speed by a conductive roller 28 in the discharge circuit. e.g. in a ship during launching. The Provisional Specification describes a system Fig. 1 (not shown) wherein a stroboscopic lamp at the receiver is triggered when the transmitter arm contacts the instrument pointer to momentarily illuminate a pointer rotating over a dial in synchronism with the transmitter arm, and thus indicate the reading of the instrument at any instant.

Filed: 1935-05-15
Abstract: 453,717. Heating vehicles. ARMSTRONG, WHITWORTH, & CO. (ENGINEERS), Ltd., SiR W. G., BECKETT, C. M., and ORTON, A., Scotswood Works, Newcastle-on- Tyne. May 15, 1935, No. 14210. [Class 64 (ii)] An internal-combustion engine 1, driving a vehicle, is connected to the usual cooling radiator 2 through a pipe 7 and thermostatic valve 17, which prevents circulation until the temperature in a tank 5 connected to the radiator outlet 8 reaches a predetermined value. A further thermostatic valve 18 prevents circulation from the engine jacket outlet pipe 4 until the temperature reaches a predetermined value. The water is supplied to heating radiators 9 through tank 5 and overflow pipe 10, the return pipe 11 delivering the water above water level in the tank 5. In order to maintain the level in the tank 5 in the event of leakage, a make-up tank 12 is connected by pipe 13 to the overflow pipe 10 from tank 5. The level in the tank 12 cannot be higher than in tank 5, but may be lower without affecting the level in tank 12. A pump 14 may be provided in the cooling system, and a pump 15 in the heating system. A baffle 16 ensures the return of the cooled liquid to the bottom of tank 5. In use, the valve 18 remains closed until the medium in the engine jackets rises to a, predetermined temperature, and then allows the medium to pass to tank 5, and thence through overflow pipe 10 to the heaters 9. The cooled medium returns through pipe 11 to the tank 5 and when the temperature in the latter reaches a predetermined point, the valve 17 opens and allows the medium to pass through the engine cooling radiator 2. In a modification, Fig. 2 (not shown), the tank 5 is closed, and steam from its upper part passes to the radiator 2 where it is condensed, and the condensate returns direct to the bottom of the tank 5.

Patent GB-751418-A (GB)
Title: Production of hexamethylene tetramine
IPC: C07D487/18
Filed: 1954-05-14
Abstract: Hexamethylene tetramine is produced by reacting gaseous formaldehyde with gaseous ammonia while introducing cold water or a cold inert gas into the reaction zone to maintain the temperature within the range of 100-140 DEG  C.  A vapour mixture, containing formaldehyde, obtained by oxidation of methanol or methane, may be used as starting material.  The water is preferably passed into the reaction zone through jets, if desired with the aid of an auxiliary gas.  The amount of water is preferably adjusted to maintain the temperature of the gaseous mixture below the desublimation point of hexamethylene tetramine (135 DEG  C.) and above the dew point of water.  The exit gases may be partially condensed to obtain an aqueous solution containing a minor quantity of hexamethylene tetramine and excess ammonia. This solution may be added to the water introduced into the reaction zone.  The desublimed hexamethylene tetramine collects at the bottom of the reactor and may be removed by a screw conveyer or swing arm.  The walls of the reactor may be maintained at a temperature below the dew point of the water vapour contained in the reaction gases so that they are kept moist whereby any hexamethylene tetramine contacting the walls will be dissolved and may be recovered by collecting the solution.  A detailed example is given.
