Title: Fuel injection system for internal combustion engines
IPC: F02M41/14
Filed: 1956-12-10
Abstract: 837,886. Starting fuel injection engines; rotary valves. ROOSA, V. D. Dec. 10, 1956 [Dec. 21, 1955], No. 37643/56. Classes 7(3) and 7(6) [Also in Group XXVIII] In a fuel injection system comprising a fuel injection pump and rotary distributer unit 10, Fig. 1, feeding a number of injectors 65, an auxiliary'pump 71 is provided for supplying fuel through the distributer at starting when the supply from the injection pump is inadequate. The unit 10 is supplied from a tank 60 through a filter 62 and incorporates a low pressure gear pump 17, 18, Fig. 4, supplying fuel through passages 21...24 to a passage 25 registering with inlet ports 32 in the distributer rotor 15. The ports 32 are connected to a passage 30 constituting the inlet and outlet passage of the injection pump which comprises a pair of opposed plungers 34 carried by an enlarged portion 16 of the rotor 15 and actuated by a circular cam 37 so that they move apart on their intake stroke when a port 32 registers with inlet 25. The plungers 34 are forced inwards on their delivery stroke when an outlet passage 40 registers with a series of outlet ports leading to the injectors. At starting the pump 71, which may be operated manually or electrically, is operated to deliver fuel to an auxiliary inlet 53 connected through a recess 51 to a passage 50 arranged so that it registers with a port 32 when the outlet passage 40 is in register with an injector delivery line, whereby the fuel from pump 71 is delivered directly to an injector. A non- return valve 54 prevents any return flow through inlet 53 when the injection pump becomes effective. The pump 71 may be arranged to deliver fuel from the tank 60, or from a collecting tank 75 situated in the leak-off pipe 68 from the injectors, or special starting fuel from an auxiliary tank 77.

Title: Split-rate meter construction
IPC: G07F17/24
Filed: 1972-08-14
Abstract: 1387310 Parking meters QONAAR CORP 14 Aug 1972 37741/72 Heading G4V In a parking meter wherein purchased time is obtained by engagement of a pawl 42 with winding means attached to a timing mechanism,  the winding means comprises a first rotatable member 100 tied to means 102 for operating the timing mechanism, a second rotatable member 110 associated with and rotatable relative to the first member 100, teeth defined by each of said members for engagement by said pawl, and a driving portion on said second member for engaging said first member but normally held spaced therefrom. The pawl engages the teeth of either the first or second members depending on the amount of previously purchased time and the denomination of coin inserted. The embodiment described accepts dimes and nickels and is arranged such that the first hour of time may be purchased for one dime or two nickels whilst the second hour costs two dimes or four nickels. Inserted coins are received in a carrier 30 rotatable by a handle 14 and during movement of the carrier the coins are cammed by segments 84 (nickels) and 88 (dimes) such that pawl 42, rotatable with the carrier, is moved into engagement with a tooth on one of the members. If, with zero purchased time, a dime is inserted, pawl 42 engages edge 126 of member 100 and continued rotation of the carrier is effective to move member 100 through 90 degrees thus establishing one hour of purchased time. Similarly if two nickels are inserted in succession the pawl will engage tooth 125 and then edge 126 also establishing one hour, the leading edges of segments 84, 88 being spaced 45 degrees apart. Member 110 is carried round with member 100 by means of spring 118 so that on the insertion of a further nickel pawl 42 engages tooth 122 of member 110 and since the lost motion between driving edge 124 of member 110 and member 100 is 22À5 degrees only 15 further minutes of time will be established. Further nickels will likewise engage teeth 121, 120 and 119. However, if a further dime is inserted with one hour of time established the pawl 42 would engage tooth 120 to provide 45 minutes of purchased time and to prevent this a blocking arm 128 is provided. This arm is moved to its blocking (dotted lines in Fig. 2) position when member 100 has been rotated through 75 degrees and ensures that pawl 42 engages tooth 121 of member 110 and that only 30 further minutes are purchased. A third dime will cause pawl 42 to engage tooth 119 and also provide a further 30 minutes. If a nickel is inserted before a dime, the dime will cause pawl 42 to engage tooth 122 of member 110 and move this member through 90 degrees, but because of the 22À5 degrees lost motion between members 110 and 100 only 45 further minutes of time will be purchased, i.e. a total of 1 hr. 15 minutes.

Filed: 1975-09-18
Abstract: 1519858 Liquid cooling of IC engine valves KLOCKNER-HUMBOLDT-DEUTZ AG 18 Sept 1975 [11 Oct 1974] 38350/75 Heading F1B A valve 1 in a valve housing 2 of an I.C. engine cylinder head 3 is cooled by liquid passing from a supply pipe 5 to a discharge pipe 7 by way of branch pipes 9, 11 and a changeover valve 10, which can be moved from a first position allowing coolant to flow via a cooling space in the valve housing 2, Fig. 1, to a second position cutting off such flow and connecting the valve housing cooling space to a drain pipe 15, Fig. 2 (not shown). The valve 10 is moved between its two positions by a mechanism 12, the arrangement being such that a valve cover 13 can only be seated on the cylinder head 3 when the valve 10 is in its first position and the valve 1 and housing 2 can only be removed from the cylinder head 3 when the valve 10 is in its second position, thus minimizing loss of coolant. When the valve 10 is moved to its second position, a bleed valve 16 opens to admit air which may be supplied by an air line to ensure that the water drains quickly from the space in the valve housing 2. In Figs. 3 and 4 (not shown), a rotary valve 17 is provided instead of valve 10 and in its position to supply coolant to the valve housing 2 (Fig. 3) an operating lever 19 allows the valve cover 13 to be mounted on the cylinder head 2; whereas in its position to drain the coolant spaces of the valve housing (Fig. 4) the lever 19 does not permit mounting of the valve cover 13. A cam 20 on valve spindle 21 actuates a bolt 22 so that the valve housing 2 and valve 1 can only be removed when the lever 19 and valve 17 are in the position to prevent coolant from flowing to the valve housing.

IPC: H02M1/14
Filed: 1928-12-31
Abstract: 307,393. Dieux, J. March 6, 1928, [Convention date]. Thermionic amplifiers.-In a mains supply unit F feeding both high and low tension to a wireless amplifier A, and comprising a buffing battery B shunted across the low-tension leads BT to reduce hum, provision is made for controlling both the supply unit and buffing battery from a single switch such as I. As shown in Fig. 3, a relay winding EA is inserted in the positive lead of the low-tension output BT from the supply unit F. So long as the main supply switch I is closed, and current is flowing through the winding EA, the contact P is closed and the buffing or smoothing battery B is in circuit. As soon as the switch I is opened the contact arm P falls away and the battery B is open-circuited and cannot deliver current to the set. The arrangement also allows remote control of the amplifier. The relay may be inserted in the main supply circuit, and the control switch I placed between the battery B and the amplifier A. The unit may also be arranged to energize an electric motor for an associated gramophone. In the Specification as open to inspection under Sect. 91 (3) (a) an arrangement is also described for reducing hum by shunting the gridfilament circuit of one of the amplifier valves by a variable resistance. This subject-matter does not appear in the Specification as accepted.

Patent GB-1107895-A (GB)
Title: Improvements in or relating to elastomeric fibers
IPC: C08G65/24
Filed: 1965-09-13
Abstract: Elastomeric fibres are formed from a vulcanized copolymer of an epihalohydrin with an ethylenically unsaturated epoxide, the copolymer before vulcanization being a linear polyether that is solid and substantially amorphous, containing in the unstretched state less than 25% crystallinity when measured by X-ray diffraction, and has a reduced specific viscosity of at least 0.5 when measured as a 0.1% solution in a -chloronaphthalene at 100 DEG  C. and which contains at least 20% by weight of epihalohydrin units and at least 0.5% of unsaturated epoxide units.  There may also be present in the copolymer other saturated epoxide units. The copolymers may be prepared by contacting the monomers with an organo-aluminium catalyst.  Any epihalohydrin may be used and specified unsaturated epoxides are unsaturated glycidyl ethers, monoepoxides of dienes or polyenes, and unsaturated glydiyl esters, many of which are listed. The elastomeric fibre is produced by compounding the copolymer with a suitable vulcanization system, spinning a fibre from the composition and then curing the fibre.  The copolymer may be vulcanized by any conventional curing method, e.g. sulphur plus an accelerator such as thiazole, thiuram, sulphenamide and dithio carbamate.  Other curatives such as diamines, ethylene thiourea, urea and ammonium salts may also be present together with a reinforcing filler, preferably silica.  Antioxidants, dyes and pigments may also be present.  The compounded copolymer may be wet spun into water from a solution in solvents such as acetone, dioxane, dimethyl formamide, dimethyl sulphoxide, benzene, toluene, xylene, methylene chloride or ethylene dichloride, and the fibre cured by heating at temperatures of 70 DEG  C. to 200 DEG  C.  The examples describe the preparation of copolymers and elastomeric fibres therefrom, of epichlorhydrin, ethylene oxide and allyl glycidyl ether; epichlorhydrin and allyl glycidyl ether; epichlorhydrin and butadiene monoxide; and epichlorhydrin, ethylene oxide and the glycidyl ester of tall oil fatty acids (60% linoleic acid, 31% oleic acid and 9% of saturated C16-C20 fatty acids.)

Title: Improvements relating to control arrangements on grinding machines
IPC: B24B49/04
Filed: 1963-10-04
Abstract: 1,022,677. Grinding. DAIMLER-BENZ A.G. Oct. 4, 1963 [Oct. 6, 1962], No. 39245/63. Heading B3D. An arrangement on a surface grinding machine for controlling the feed of the grinding tool on the attainment of a required grinding dimension comprises a vibratory resilient feeler which is arranged to make contact with the tool when this dimension is attained, which feeler projects from the work carrier towards the grinding tool perpendicularly to the plane of grinding. A surface grinder has a grinding head 4 movable vertically on a guide of the bed and comprising a grinding disc or a number of abrasive segments 3. A rotatable work-table 2 is movable horizontally on the bed from a loading/unloading position to an operative position with respect to the grinding head. Workpieces 7 are held on the table 2 by electromagnetic means 6 energized through carbon brushes 12, 12 contacting rails 11, 11 on the table. A feeler T is mounted on the table 2 with adjustment for height. When the feeler contacts the grinding tool, a control pulse is generated, e.g. piezo-electrically, inductively or capacitatively, and is fed through a pre-amplifier V, capacitative or inductive couplings 17, 17<SP>1</SP>, electric filter Si and amplifier N to a control relay R. At a predetermined workpiece thickness, the downward feed of the grinding head is stopped. Simultaneously, or after a time interval, the grinding head is moved upwardly, rotation of the grinding tool is stopped, and the worktable is moved to the loading/unloading position. More than one feeler may be used, set at different levels, e.g. a first feeler effective to slow down the feed and a second feeler effective to stop the feed. A feeler which has emitted its control pulse may be lowered to an inoperative position, being returned to operative position at the beginning of the next cycle. Alternatively, a single feeler may be selectively moved to several control positions. Reference has been directed by the Comptroller to Specification 850,023.
