Title: Internal combustion engine operating condition control systems
IPC: F02M25/07
Filed: 1976-09-07
Abstract: 1527935 Regulating IC engines NISSAN MOTOR CO Ltd 7 Sept 1976 [11 Sept 1975]  36977/76 Heading FIB An I.C. engine comprises a combustion chamber including main section 4, auxiliary section 5 which communicates with main section 4 through orifice 6, carburetter 2 having throttle valve 39, an induction passage 3 connecting the carburetter to main section 4 only, spark plug 11 in auxiliary section 5, exhaust passage 13 leading to reactor 8 having secondary air injection means 15 and exhaust gas recirculation means 26, 27, 28. Means 38 or 40 control movement of the throttle valve toward a closed position during engine deceleration in order to prevent a sudden increase in the vacuum in induction passage 3. The rate of movement of the throttle is controlled by a dashpot 40, or alternatively the throttle valve is linked to diaphragm motor 38 which is subject to the induction passage vacuum and tends to open the throttle valve as the vacuum increases. Additional air is also admitted to induction passage 3 when the vacuum exceeds a predetermined value, through passage 42 controlled by valve 41 actuated by vacuum motor 43. The volume of reactor 8 is one to four times the total engine displacement volume. Passage 13 and reactor 8 have a heat conserving liner 16. Exhaust pipe 25a has a liner 25 which defines an annular space through which the secondary air flows and in which it is heated. Secondary air is supplied by engine driven pump 19 and a normally closed valve 20 is opened by the biasing spring of vacuum motor 21 when the induction passage vacuum is low. Valve 24 operates to vent line 23 to atmosphere when the reactor temperature is too high and is energized through temperature sensor 22. Exhaust gas recirculation is controlled by valve 27, actuated by vacuum motor 28, at 5-30% of the flow-rate of the intake air. Exhaust pipe 7 between silencers 29 and 30 has a heat shield 31. Combustion air which has been heated by passage through chamber 54 is drawn into air filter 1, the proportion of heated to unheated air being controlled by valve 34 which is actuated by vacuum motor 36. Increase in induction passage vacuum causes increase in the proportion of heated air. An air temperature sensor prevents the vacuum acting on motor 36 when the intake air is above a predetermined temperature. Ignition advance apparatus 45 acts on distributer 46 to reduce the ignition timing advance as the induction passage vacuum increases. Full ignition advance is provided at high engine speed by engine speed sensor 51 which causes solenoid 50 to be energized and thus opens air vent passage 48 and breaks the vacuum on motor 45. Device 37 shuts off the fuel supply when the engine is switched off. Switch 52 is closed by temperature sensor 53 when the engine is cold, to fully advance the ignition.

Title: Improvements in or relating to metal coated materials
IPC: C23C24/06
Filed: 1928-12-14
Abstract: 326,792. Cutler, L. W., Klein, C. A., and Associated Lead Manufacturers, Ltd. Dec. 14, 1928. Bronzing and the like.-Surfaces are metallized by applying a film of an adhesive, reducing it to a slightly tenacious condition, depositing metal powder thereon, rubbing the powder to distribute it over the film and attach it firmly thereto, and then subjecting the surface to pressure to flatten out the metal particles and produce a continuous film of metal. A porous backing, e.g. paper, may be impregnated with a waterproof adhesive and then coated with metal, the material being thus waterproofed throughout as well as metalcoated. The adhesive may be bitumen, preferably a mixture of a hard high-melting-point bitumen with a soft, low-melting-point bitumen in solution in a volatile solvent, e.g. naphtha, carbon tetrachloride, or white spirit. A resin, e.g. a hard oil-soluble phenol formaldehyde resin, is preferably added to the solution. In the manufacture of lead-coated paper, a web of paper from a reel 1 is fed continuously through an impregnating bath 2 of adhesive to a drying chamber 5 where a temperature not exceeding 60‹ C. is maintained to evaporate the solvent from the adhesive, and is then reeled at 6. It is then passed to a metal-coating chamber 11 in which it is fed continuously through the space between two oppositely travelling endless belts 7, 8, the linear speed of which is greater than the speed of the paper so that a rubbing action is exerted. Containers 14, 10 deliver lead powder on to the upper surface of the paper web and the upper surface of the lower belt respectively, the powder being carried to the interfaces of the belts and the web and rubbed into the adhesive which is rendered slightly tenacious by maintaining a temperature of 60‹ C. to 70‹ C. in the chamber 11. The coated paper then passes to the burnishing rolls 16 which flatten out the metal particles and form a continuous metal film. Buffing wheels 17 and felted rollers 18, 19 dipping in baths of lacquer may be provided to polish the film and coat it with lacquer, the surface being finally dried in the drying chamber 20. Instead of burnishing rolls 16 the surface may be rolled with steel shot and a second metal coating may be applied to the first by electro or chemical deposition. Specifications 20542/04 and 305,515 are referred to.

Title: Improvements in world wide navigational system
Inventor: GRAY JOHN WIGHTMAN
IPC: G01S13/60
Filed: 1955-12-29
Abstract: 814,744. Radio-direction finding. GENERAL PRECISION LABORATORY Inc. Dec. 29, 1955, No. 37346/55. Drawings to Specification. Class 40 (7). [Also in Group XX] In an aircraft great circle, radio-echo navigation system in which a craft may home on a selected point without terrestial or celestial fixes, other than the initial one, to allow for the inaccuracies introduced by the convergence of meridians at the Poles of the Earth, the computing co-ordinate system is automatically rotated by one right-angle to form a transverse co-ordinate system, when the craft is at a specified distance from the Poles. The integrators which compute the instantaneous craft position operate in terms of the transverse co-ordinate system and can owing to the coordinate change, operate normally so as to continuously integrate the orthogonal components of the ground speed vector. The craft ground speed and drift angle are determined by a Doppler radar system of the pulse type, having three directive arrays to provide forward and laterally directed beams inclined towards the Earth. The ground track angle is determined by a heading reference unit which combines the heading angle with the drift angle. The instantaneous latitude and longitude, which are computed by combining the outputs of the Doppler system and the reference unit, are applied to a second computer which derives the great circle course and the distance to destination. The output of the magnetic compass of the heading reference unit is stabilized against high-frequency oscillations by a feed-back loop and when, at the North Pole, it fails to function, it is replaced by a directional gyroscope. In addition, a correction for magnetic variation with position is added. The gyroscope is normally monitored from the magnetic compass by means of a second feed-back loop which is supplied with information from the longitude and latitude computer which corrects the gyroscope for both the Earth's rotation and the relative movement of the craft and Earth.

Title: Apparatus in a computing device for controlling program instructions
IPC: G06F9/42
Filed: 1961-10-19
Abstract: 979, 716. Digital computers. MONROE CALCULATING MACHINE CO. Oct. 19, 1961 [Nov. 7,1960], No. 37493/61. Heading G4A. In a computer, program sequencing is controlled by a circulatory loop comprising a "control" register 10 capable of registering one 4- character instruction and an "instruction" register 12 capable of registering two 4-character instructions. Normal sequencing. At least one of the three instructions in the loop must be of a type called a "jump" instruction (J, Fig. 3) effective when in the control register 10 to cause the transfer of an instruction word comprising two instructions from the computer storage 16 to the instruction register 12. This jump instruction J, Fig. 3,causes transfer of an instruction word comprising instructions A and B to the instruction register 12. During its circulation from the control register 10 to the instruction register 12, the jump instruction J is incremented by unity in an adder 15 (see Fig. 4) so that when instructions A and B have been executed in turn in the control register 10 the next instruction work in sequence in the computer storage is entered into the instruction register 12. Branch instructions. The normal sequencing is interrupted if one of the A or B instructions is a "jump mark" instruction. When an instruction of this type is inthe control register it is effective to address a memory location determined by the instruction and exchange its contents with the contents of the instruction register 12. Thus program branching to achieve entry into a subroutine is effected. Exit from the subroutine is by an instruction addressing the register in store containing the former instruction register contents which are replaced in the instruction register to resume sequencing of the main program. Hardware. The register 12 and store 16 can be on a magnetic drum and the control register 10 may be of the flip-flop type.
