IPC: F02M59/46
Filed: 1951-11-08
Abstract: 706,648. Fuel-injection pumps. BRYCE FUEL INJECTION, Ltd. Oct. 31, 1952 [Nov. 8, 1951], No. 26189/51. Class 102 (1). A fuel injection pump delivery valve 2 hasdashpot mechanism to afford both a delayed opening of the valve to ensure rapid opening of the injector nozzle needle and a delayed closing to prevent dribble. The valve 2 slides over a cylindrical portion 1a of the valve seat member 1 and is urged into the closed position by a spring 3 housed in a connector 4 connected to the fuel delivery line. The valve member 2 has an axial fuel passage 1b leading from the pump chamber B and radial ducts Ic leading to a groove or port 1d in the wall of portion 1a. A restricted orifice 1e connects the passage 1b with the interior space V of the valve 2 and during the delivery stroke of the pump delays the opening of the valve until the pressure in space V is sufficient to lift the valve and open the port 1d. During closing of the valve, after the ports Id have been closed the fuel trapped in the space V escaping slowly through the orifice 1e acts as a dashpot to retard closing. In a modification the upper end of the passage 1b. is closed by a spring-loaded plate valve having a restricted groove in its underface. In another modification (Fig. 3) the valve 2 is a conical valve with a cylindrical skirt the space V below which acts as the damping chamber. Fuel passages 1b in the valve seat 1 communicate with a groove 1a that, due to a reduced portion 2a of the skirt, communicates with the fuel delivery line when the valve is open. A restricted orifice 1e may be provided between the pump chamber B and the space V or the valve skirt may have a central fuel passage 1b communicating with the groove 1d by a restricted radial.passage 1f. In yet another modification the valve skirt is fluted and carries a small pintle located with clearance in a hole in the valve seat member, the clearance acting as the restricted orifice.

IPC: C08K5/5399
Filed: 1960-07-28
Abstract: The light-fastness of polychlorobutadiene or copolymers thereof is improved by adding to the polychlorobutadiene or copolymer a compound of the general formula R-SO2-N=P(-X-R1)3 wherein X represents an oxygen or sulphur atom, and R and R1 (which may be the same or different) each represent a substituted or unsubstituted alkyl, cycloalkyl, aryl, aralkyl or alkaryl radical and wherein R can also represent a monosubstituted or a disubstituted amine radical. The radicals R and R1 may contain as substituents hydroxy, halogen, nitro, amino, ether or thioether radicals.  Radical R is preferably one of the following:  <FORM:0916118/IV(a)/1> The alkyl radicals are preferably lower alkyl radicals containing up to 6 carbon atoms. Radical R1 is preferably one of the following: <FORM:0916118/IV(a)/2> The alkyl radicals may contain from 12 to 20 carbon atoms.  The following compounds are specified: <FORM:0916118/IV(a)/3> 0,01 to 5%, based on the weight of the polymer or copolymer, of the compound may be added either on a roller prior to vulcanizing or in an internal kneader, or to a dispersion or emulsion of the polymer latex.  It is stated that the addition of the compounds not only cancels out the discolouring influence of amines or phenols employed in the polmerization of the polymer or copolymer, but results also in a light-stabilizing action.  Examples are directed to the light stability of polychlorobutadiene test mixtures containing CH3-SO2-N=P(-S-C12H25-norm)3 or one of the following compounds:  <FORM:0916118/IV(a)/4>

Title: Method and apparatus for freeing castings from sand lined molds
IPC: B22D13/10
Filed: 1926-10-25
Abstract: 269,072. Croad, A. K., (Sand Spun Patents Corporation). Oct. 25, 1926. Drilling-machines; drills.-A method of freeing castings from sand moulds is described with reference to centrifugally cast pipes. The moulds are rolled from the casting-machine along rails and on to rails 17 shaped to receive the moulds and supported in notches in a frame 20. Other rails on the opposite side of the frame serve for the discharge of the emptied moulds. A carriage 13 notched at 22 to engage the rails 17 is tilted by a rope 36 passing over the pulley shown and operated by a hydraulic cylinder 33 to raise the moulds to the position shown in full lines in Fig. 1, in which they are in alignment with a corresponding number of annular drills 5 each driven by a motor 6 through speed reducing gearing 7. Flanges 52 on the flasks engage a bar 51 on the carriage to resist the thrust of the drills, which are fed by ropes 42 connected to a common carriage 3 running by wheels 4 on guide rails. The ropes are connected to one or more hydraulic cylinders 44. The apparatus may be constructed as a single spindle machine. The drills 5 are guided at 25 to pass between the castings and the flasks and are constituted by toothed rings 9, Fig. 4, welded to tubular shanks 5 perforated at 8 for the escape of sand. The broken-up sand passes by gravity to and is collected in a hopper 27 from which it may pass to retempering plant. In a modification the drills are fed by a counterweight and are returned hydraulically. The freed castings are drawn out on to a further pair of rails (not shown) on which they pass to a cooling bed &c. When the pipes have a socket end a cross pin in the drill shank engages the spigot end of the pipe just before the cutter reaches the socket and causes the castings to move forward with the drills, thus protecting both the cutters and the sockets from injury. In a further modification, for use when the shrinkage of the casting is considerable, the drill has a cutting end 73 slotted at 74 and mounted on a head 71 screwed into a shank 70 of reduced diameter. The head is grooved at 75 to facilitate escape of sand. An abutment 77 mounted on the plug by means of the retaining bolt and ball bearings shown engages the end of the casting soon after the teeth of the cutter have become operative.
