Title: Fuel supply system for compression ignition engines
IPC: F02M37/36
Filed: 1973-07-19
Abstract: 1431393 Preventing air locks in fuel systems FORD MOTOR CO Ltd 19 July 1973 34444/73 Heading F1B In a compression ignition engine in which a pump 5 pumps fuel from a tank 1 to a filter 7 having a restricted by-pass connection 19 from its dirty side to a reservoir 11 and a connection 21 from its clean side to an injection pump 9, the fuel filter is arranged so that any fuel pumped from the dirty fuel side to the clean fuel side flows downwardly to the injection pump whilst fuel bypassing the filter element is pumped to a level higher than the injection pump, the injection pump 9 has a bleed 25 to an auxiliary tank 23 the reservoir 11 and auxiliary tank 23 having outlets higher than the inlets from the filter and the injection pump, the arrangement being such that air in the fuel connections tends to be pumped into the reservoir. In operation pump 5 supplies injection pump 9 through filter 7 so that air that may be present tends to pass through pipe 19 to reservoir 11. The bleed from injection pump 9 consists of filtered fuel and fuel in the auxiliary tank 23 feed a starting device 37. Any excess fuel in the auxiliary tank flows over wall 29, Fig. 2 through a filter 31. When the engine is stopped the head of fuel in the reservoir and auxiliary tank causes a slight pressure in the injection pump 9 which prevents air entering the system. The fuel filter 7 is mounted on the engine so that any fuel by-passed to the reservoir and discharged into the fuel tank heats the fuel in the latter.

Title: Improvements relating to the treatment of metal surfaces
IPC: C23C22/83
Filed: 1966-08-01
Abstract: A chemical conversion coating is formed on a metal surface, e.g. of steel, brass, bronze, Fe, Zn, Al, Cu, Mg, Ti or alloys thereof, particularly galvanized steel sheet or strip, and the coated surface is given a chromate rinse with a solution containing by weight at least 0.001% of trivalent Cr in the form of a chromium chromate complex, at least 0.005% Zn and at least 0.002% F.  The rinse solution may be formed by reducing chromic acid solution with sufficient reducing material, e.g. a mono-, di- or polyhydroxy alcohol, an aldehyde, phenol, or a carboxylic acid, Li, Al, Zn, Li borohydride or tetrachloride, ZnH2 or "Raney" (Registered Trade Mark) Ni, to reduce 1 to 60% of the hexavalent Cr to trivalent Cr, and then adding Zn and F ions to the resultant solution, e.g. as ZnO, ZnCo3, Zn (OH)2 or metallic Zn, and HF, NaF or NH4F, preferably ZnF2, and diluting to the desired concentration; preferably the pH of the solution is 2.5-4.5.  The conversion coating may be of phosphate (e.g. of Zn, Fe, alkali metal or ammonium), oxide, sulphide, oxalate, chromate or arsenate.  For example, a complex oxide coating on a zinc or galvanized surface is formed by treatment with a chromate-free alkaline solution (pH more than 11) containing a metal, other than a Group 1 metal, that cannot exist in the alkaline solution as a free ion but is complexed with an organic complexing agent, as described in Specification 1,042,108; e.g. a solution containing NaOH, Na hexahydroxyheptoate as sequesterant, ferric nitrate and cobalt nitrate. Other conversion coating solutions are specified containing: (a) CrO3, HF, Al, K4Fe(CN)6; (b) Zn, PO4, Ca, NO3, ferric ion.  The coated and rinsed surface may be subsequently protected by applying thereto an acrylic, epoxide or alkyd finish, preferably after a deionized water rinse.

Title: Improvements in television systems
IPC: H04N5/06
Filed: 1934-12-05
Abstract: 451,578. Television. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Dec. 5, 1934, No. 34895. Convention date, Dec. 6, 1933. Addition to 445,428. [Classes 40 (iii) and 40 (v)] The parent Specification discloses a method of producing synchronizing signals of greater amplitude than the image signals and indicates. a receiver in which separation is performed by a valve biassed to pass only the synchronizing signals. According to the present invention, the separating valve is a gas-filled hot cathode valve and is preferably a diode. The rectified received signals are applied over condenser 5 to the cathode-ray tube and over condenser 7 to a gas-filled diode 9 biassed to pass current only when a synchronizing impulse arrives. Transformers 11, 12 separate line and frame impulses and control relaxation oscillation generators. The line frequency transformer is associated with a phase retardation network 20, 23 to compensate for retardation produced by the transformer. Automatic volume control potentials for high-frequency amplifiers may be taken off at 19 from a condenser resistance combination 13, 14, traversed by the synchronizing impulses which are transmitted at constant amplitude. Specifications 441,761 and 447,401 are referred to. According to the Specification as open to inspection under Sect. 91, the automatic volume control potentials may be amplified; a network 17, 18, Fig. 2 (Cancelled), allows only the synchronizing signals to pass to the grid of valve 15 and automatic volume control potentials are taken off from resistance 16. Phase retardation produced by transformer 11 may be prevented by making the natural period of oscillation of its secondary longer than the impulse duration. This subjectmatter does not appear in the Specification as accepted.
