Filed: 1974-10-26
Abstract: 1518098 Rotary positive-displacement fluid-machines WANKEL GmbH 27 Oct 1975 [26 Oct 1974] 46426/74 Heading F1F A motive-power assembly comprises a 3:4 type Wankel I.C. engine 1, which may have two rotors, a compressor 3 supplying partially compressed air to the engine and driven by a gas turbine 2, and a combustion chamber 4 for the turbine containing a fuel nozzle 4a and receiving exhaust gases from the engine and also air from the compressor through a by-pass duct 5. The air supply to the engine may be shut-off by a valve 6 so that the engine can be stopped while the turbine and compressor continue to operate. The turbine may be started by a motor at A. The compressor may be furnished with an aftercooler 7. A restriction in the duct 5 may be adjustable. The turbine and compressor may be multi-stage. In the engine the air enters through a port 11 and after further compression receives fuel from a nozzle 13, ignition being effected by either a spark-plug (not shown) or by the heat of compression. Partially expanded combustion products are transferred from the respective chamber to the leading adjacent one through a port 16 while the latter is being traversed by the intermediate apex of the piston 8 so that expansion occurs in two stages. Additional fuel may be injected through a nozzle 19. Exhaust gases are discharged through a port 18.

Filed: 1970-10-08
Abstract: 1285494 Suspension levelling systems FICHTEL & SACHS AG 8 Oct 1970 [25 Oct 1969] 48019/70 Heading B7D In a vehicle suspension system having air springs 2a, 2b associated with suspension struts 1a, 1b connected through a conduit system to an air compressor 4 and a height reducing valve 7 controlled by a level-regulating switch 9, the spare wheel 12 of the vehicle is utilized as an air storage chamber for supplying the compressor 4. The pressure in the spare wheel 12 is maintained at a pressure higher than is needed for carrying the vehicle, and should the pressure therein fall below a predetermined value a change-over valve 11 connects the compressor inlet to atmosphere. When the suspension level is too low a motor 5 which drives the compressor 4 is energized by the switch 9 through a relay 8, and when the level is too high the switch 9 energizes the valve 6 so that air from the springs 2a, 2b flows back to the spare wheel 12 which is at a lower pressure. A relief valve 7 prevents excessive pressures in the system. Air is supplied to and withdrawn from the springs 2a, 2b through a distributor 3 which prevents pressure equalization between the springs under unequal loading. In a modification, a solenoid in the change-over valve is energized when the suspension height is being lowered so that air from the springs flows back into the spare wheel even if the pressure therein is below the predetermined value.

Title: Improvements in or relating to evaporation process and apparatus
Inventor: CALLARD ANTHONY GILBERT
IPC: B01D1/00
Filed: 1963-12-10
Abstract: In a submerged combustion evaporator, which is suitable for the concentration aqueous liquors containing metal chlorides and hydrochloric acid, the outer surface of the dip tube is made of titanium and the inner surface is made of titanium or non-metallic refractory material.  The dip tube leads the hot combustion gas from the combustion zone to below the surface of the liquor to be evaporated.  The dip tube is preferably surrounded by a tube which promotes circulation of the liquor in contact with the outer surface of the dip tube whereby the temperature of the dip tube is maintained below the temperature at which failure of the tube would occur.  The circulation tube may be made of titanium or of some other metal covered with a synthetic resin coating.  When hydrochloric acid is present in the liquor it is desirable that at least 0.1% by weight of a heavy metal (e.g. FeCl3) is also present as a corrosion inhibitor. The apparatus is particularly suitable for the concentration of liquor from the hydrochloric activation of montmorillonite clay.

Title: Method of forming members comprising moulded parts surrounded by metal sheathing
IPC: C08L61/10
Filed: 1976-11-25
Abstract: In this process for producing and subsequently increasing the heat resistance of a phenolic resin moulding with a metal covering which surrounds the phenolic resin moulding, the production takes place by an injection moulding process, the metal covering being inserted into the mould before the injection moulding, whilst the increase in the heat resistance is carried out by a heat treatment. The aim of the invention is to produce a composite body comprising metal covering and phenolic resin moulding which is produced by injection moulding, is homogeneous and is free of cracks. To this end a metal covering with a porous structure is used in order that the volatile substances which escape from the phenolic resin moulding during the production and subsequent heat treatment can pass through the metal covering.

Title: Four-stroke internal combustion engines
IPC: F02B1/04
Filed: 1972-11-01
Abstract: 1409811 Supercharging I C engines G S POUIT 1 Nov 1972 [5 Nov 1971] 50330/72 Addition to 1354099 Heading F1B The parent Specification 1354099 claims a method of supercharging multi-cylinder I.C. engines wherein the depression which exists at the exhaust port of one of the cylinders, following the initial discharge of exhaust gas, is made to act at the intake port of a second cylinder out of phase with respect to the first by a half-cycle period and the present invention modifies this method by providing a heat storing element located in the exhaust space at a location where the exhaust gases are still at a temperature close to the temperature at which the gases flow out of the cylinder. The flattwin four-stroke engine shown in Fig. 1 has an inlet pipe 8 leading to the intake space 7 of each cylinder. A reverse flow restrictor 13 is positioned in the pipe 8 upstream of the mouth of a communicating passage 12 which leads to the exhaust port 10 of the other cylinder. A reverse flow restrictor 11 is positioned downstream of the outlet of the passage 12. An air inlet 18 in the passage 12 has variable area inlet ports 17 and is connected to the main throttle control of the engine through a one-way linkage which is effective to close the air inlet ports 17 against a spring which tends to open the ports. A dashpot controls the rate at which the spring opens the ports as the main throttle control of the engine is moved towards the open position. A spring-loaded non-return valve 37 is situated in the outlet of the passage 12 and complements the action of the reverse-flow restrictor at low engine speeds. Once the engine has reached a predetermined speed the valve 37 opens and then remains open, due to its inertia, throughout the four strokes of the cycle. In operation, the rarefaction which exists in the exhaust port 10 immediately after the initial discharge of gases from the cylinder 2, is communicated by the passage 12 to the intake pipe 8 and acts to supercharge the engine. A small quantity of fuel/air mixture enters the pipe 12, mixes with additional air which enters through the ports 17 and is directed into the space around the reverse flow restrictor 11, where it causes combustion of the carbon monoxide and unburned hydrocarbons in the exhaust gas, and also reduces the amount of nitrogen oxides in the gas. To promote this combustion, by increasing its temperature, the restrictor 11 is insulated from its support 29 by heat insulating washers 27, 28 and a sleeve 26. Combustion may also be assisted by coating areas 30 of the restrictor with catalytic material, or making these areas of catalytic material. Figs.4 and 5 (riot shown) illustrate the application of the invention to a two-rotor Wankel engine.
