Title: Transferring device for objects in which a reduced pressure is  applied continuously
IPC: B22C9/03
Filed: 1974-08-09
Abstract: 1450873 Foundry moulding SINTOKOGIO Ltd 9 Aug 1974 35163/74 Heading B3G A system in which a line of objects, e.g. moulding flasks 3, in which a reduced pressure is continuously applied, is intermittently advanced on a roll conveyer 1, comprises a closed stationary chamber 4 connected to a vacuum source 7 and carrying piston and cylinder assemblies 8, 9, each of which assemblies operates a pair of normally closed valves 15 to which vacuum lines 22 are connected from the chamber. Each valve becomes aligned with a normally closed valve 2 in the wall of an object after each step of movement of the line; during the pause in the movement, the assemblies 8, 9 are operated to bring valves 2 and 15 into abutment and to open them thereby subjecting the objects to vacuum. Movement of the valve assemblies 15 is guided by a bar 14 which engages a recess 13, Fig. 2. Similar valves 2a, 15a are positioned in and adjacent, respectively, the opposite walls of the objects and are operated by similar means, except that such means are carried by a closed vacuum chamber 30 carried on rollers 32 and reciprocable parallel with the line. Having opened the valves 2, 15, the opposite valves 2a, 15a are opened whereby communication is also effected with the chamber 30. Valves 2, 15 are then closed and the line of objects is moved one step carrying with it the chamber 30 which is still in vacuum communication with the objects. On stopping the line, valves 2, 15 are aligned and opened whereupon the valves 2a, 15a are disconnected and closed and the chamber 30 returned to its original position by a piston and cylinder 33, 34, ready for the next movement step. Instead of applying vacuum directly to vacuum sealed flasks 3, the vacuum may be applied directly to a line of boxes 40, Fig. 7, from which flexible connections 22 are made to moulding flasks 53, 53a. The flasks may be used for a process in which sand is compressed therein by the application of vacuum, which causes atmospheric pressure to be applied to a flexible film covering the sand supply opening; a thin synthetic resin film covering the surfaces of a pattern in the flask is drawn towards the sand by the vacuum.

Title: Re-use of waste gases in the working process of piston internal combustion engines
IPC: F01N5/00
Filed: 1960-10-17
Abstract: 969,207. Regulating multi-fuel I.C. engines. MASCHINENFABRIK AUGSBURGNURNBERG A.G. Oct. 17, 1960 [Oct. 17, 1959], No. 35528/60. Drawings to Specification. Heading FIB. The proportion of combustion gas retained in the working cylinder of a multi-fuel engine is regulated by means of a working gas control device and in dependence on the exhaust gas composition or soot content, the amount of fuel supplied per cycle or unit of time, or operation variables that are typical of or control the heat condition of the engine such as the exhaust gas, engine coolant or engine lubricant temperature or the temperature of suitable engine components, so that widely different fuels can be burnt with little obnoxious exhaust emission and without undue fuel consumption under all operating conditions, combustion noise and maximum combustion pressure being kept low. Regulation is effected so that as engine temperature decreases the proportion of retained gas increases. The working gas control device may be a valve in the exhaust pipe, or an overhead cylinder exhaust valve the stroke and/or timing of which is controlled by mounting its rocker on an eccentric bearing or by using slidably or rotatably adjustable cams or camshafts, or cam levers of variable transmission ratio. Alternatively, the device may be a rotary cylinder exhaust valve having a rotatable regulating sleeve, or cylinder inlet valve suitably controlled as to stroke or timing. In supercharged engines, the exhaust closing and/or inlet opening time may be altered, so adjusting the scavenging overlap. The device may be a valve proportioning intake air flow between an indirect heat exchanger, where it is warmed by exhaust gas or engine coolant, and a by-pass therefor. Manual override of regulation to increase the proportion of retained gas and minimize obnoxious exhaust emission may be provided. The invention is applicable to Otto and Diesel two-stroke and four-stroke engines. Specification 901,711 is referred to.
