Filed: 1971-08-04
Abstract: 1366295 Change speed control; cams WILSON MILLER & CO Ltd 4 Aug 1971 [5 May 1970] 8484/74 Divided out of 1360596 Headings F2D and F2K A toggle switch 21, producing an electric signal for kickdown in an automatic, auxiliary or overdrive transmission, controlled, e.g. by the electronic control of the main Specification, is actuated by a cam 27, which is turned clockwise by the opening movement of the throttle pedal to pass through the following stages. From zero to a predetermined small opening, a cam follower 26 rides over a first cam region during which the switch arm 23 remains in the open position D. Further movement over a second cam region 29 moves the switch arm through position C to E, the switch remaining open. Finally over a third cam region 30, the switch arm is moved through position B to the closed position A, producing kickdown, which persists throughout further throttle opening movement. During the return closing throttle movement, on reaching the cam region 29 the switch arm is permitted to return through position B to E, the switch remaining closed. On reaching the first region 28 at closed, or part throttle, the switch arm is permitted to pass through position C to D in which the switch opens and overdrive is cancelled. In Fig. 2 the lengths of the cam tracks can be adjusted by turning slotted segments 33, 34 under retaining screws 35.

Title: Method of making a metallic simifinished product
IPC: B22D11/00
Filed: 1974-02-25
Abstract: 1426314 Making metallic semi-finished products; welding by pressure; continuous casting OLSSON INTERNATIONAL Inc 25 Feb 1974 [5 March 1973] 8526/74 Headings B3A B3R and B3F A method of making a metallic semi-finished product comprises, continuously solidifying a layer of molten metal on the surface of a rotating chilled roll, an endless belt or a succession of mould elements which has its lower portion immersed in molten metal 8 in a vessel 2, the layer being of a thickness less than that of the semi-finished product, stripping the layer from the roll &c. and either deforming the layer so that portions of the layer are immediately adjacent one another and pressing the portions together or pressing a plurality of simultaneously formed layers 10, 12, 15 together, the pressing operation fuse-welding the portions or the layers 10, 12, 15 together at a solidus temperature at which the metal has insufficient plastic strength for normal hot rolling but where liquid metal is not visible. On one or more rollers a number of narrow strands may be formed sideby-side to be fused together subsequently. As shown, the molten metal is discharged from a ladle 3 and maintained at a constant level in the vessel. A plurality of rollers 5 are partially immersed in the molten metal and strippers 11, 14, 18 remove the solidified layers of metal off of each one. Release material is applied to each roll surface by means 21 and as the molten metal rises through a false bottom 23 in the vessel 2 baffles 24 keep slag or other surface impurities away from the rolls 5. The layers 10, 13 are fuse-welded by a roller 13 and the combined layers are welded to the layer 15 by a roller 16. The strip so formed passes through a guide 19, which is an extension of a hood 9, and when it is at the required rolling temperature it is passed through reducing rolls 25. Inert or non-oxidizing gas is supplied to the hood and the guide 19 restricts escape of the gas. A single strip only may be formed and it is folded over longitudinally until the required thickness is obtained, Figs, 3-6 (not shown), or it may be rolled longitudinally and welded into a coil to form a tube or rod, Fig. 7 (not shown). Two rolls, each dipping into molten metal may produce separate layers to be pressurewelded in the pals. In a further embodiment a single corrugated roller (30) is used. Fig. 2 (not shown), and the corrugated layer (32) is compressed into bar form (35) between rolls (34). The fuse-welding of the layers, which are preferably 5-12 mm. thick in the case of a killed steel, prior to reduction rolling ensures that the majority of the metal is from the chill zone whereby its composition conforms closely to that of the molten metal and its mechanical proportion are superior to those of metal which has solidified slower.

Title: Improvements in and relating to fuel injection pumps for internal combustion engines
IPC: F02D1/00
Filed: 1934-03-20
Abstract: 418,565. Fuel - injection pumps. HANSEN, P., 3, Svejgaardsvej, Hellerup, Copenhagen. March 20, 1934, No. 8677. [Class 102 (i).] In a means for regulating the output of several fuel injection pumps, a rod 5 is actuated by the governor and has mounted upon it bell-cranks 3, each of which has a forked end connected to the regulating member 2 of a pump. The end 3<1> of each bell-crank is arranged between a spring 7 and a set screw 6 which is adjustable to set the output of an individual pump. When the rod 5 is moved to reduce the output, should any regulating member 2 be jammed, then the bell-crank overcomes the resistance of the spring 7 so that the bell-crank is released from the regulating member 2 and the output of the remaining pumps may be reduced.

Abstract: 914,485. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. March 2, 1961 [March 15, 1960], No. 9184/60. Class 39 (4). [Also in Group XXVIII] Apparatus for determining the location of perforation defects in the sheaths of nuclear fuel elements comprises a first member defining an annular draw-off groove and a second member defining a helical draw-off groove concentric with the annular groove so that as a fuel element containing a sheath defect, through which can escape a pressurized detector gas, is advanced through the members at least two indications of the detector gas are obtained, one when the defect passes the annular groove and the other when it passes the helical groove. In the apparatus shown in the drawing a nuclear fuel element 1 is first placed in a pressure vessel 3 where it is subjected to nitrous oxide at a pressure of about 250 p.s.i. for several hours. The element is then passed at a steady speed (e.g. 4 inches per minute) through the test apparatus comprising a member 5 provided with an annular groove 12 communicating with a nitrous oxide gas detector, and a helical member 6 provided with a helical groove and with tappings 8 connected to a gas detector. Thus the time of occurrence of gas detected in groove 12 gives the axial location of a perforation in the wall of the fuel element, and the time gas is detected in member 6 gives the angular location. Other gases such as argon or helium may be used in place of nitrous oxide.

Abstract: 741,322. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 29, 1954 [April 2, 1953], No. 9207/53. Drawings to Specification. Class 40 (3). The " surround " of a screen on which a moving picture is displayed (e.g. television or cinematographic pictures) is formed from one or more electroluminescent panels, the excitation voltage for which is modulated according to the average picture brightness. The panels comprise a coating of phosphor (e.g. zinc sulphide) spread over a transparent conducting surface mounted on a sheet of glass and backed by a metallic (e.g. vaporized aluminium) coating between which and the transparent conducting surface the excitation voltage is applied, the "surround" being formed by a frame constructed from these panels. The excitation voltage may be derived either from a separate oscillator or from the line time-base circuit or the (separate) E.H.T. oscillator of a television receiver and is modulated in amplitude by video signals preferably supplied via a smoothing circuit (to prevent flicker). Television receivers having A.G.C. circuits with suitable time constants provide such smoothed signals. Alternatively the modulating video signals may be employed without smoothing by employing a long-delay phosphor. Specifications 460,508, [Group XX], 531,295 and 534,973 are referred to.
