Title: Improvements in and relating to combustion engines
IPC: F02G3/02
Filed: 1928-03-02
Abstract: 313,024. Hooker, W. S. March 2, 1928. No Patent granted (Sealing fee not paid). Combustion product engines. - In a multicylinder engine, air is supplied by a blower built into the flywheel, to a passage 14 in each cylinder in permanent connection with the corresponding crank case; at the end of the power stroke a terminal exhaust port 33 is opened and the cylinder scavenged. The air trapped in the cylinder after closure of the air-admission and exhaust ports is compressed and delivered past a non-return valve 17 to a combustion chamber 22 common to all the cylinders. Fuel burns continuously in this chamber, which may be water-jacketted or lagged internally or externally. The combustion products are supplied to the cylinders through a manifold, admission to the cylinder being controlled by valves 27, and a non-return valve 23 is placed at the outlet of the combustion chamber. The liquid fuel is supplied past a handadjustable control valve, the central part 41 of which serves to stop the supply of fuel and the lower part has a drainage passage 43. The fuel in the supply tank may be put under pressure by a connection from the air supply to the combustion chamber. At starting, petrol may be supplied to a recess 46 in the admission pipe to the chamber 22; a sparking plug is also provided therein. If desired, water may be injected into the chamber and, to assist in the scavenging at the end of the out-stroke, a small hole may be made in each valve 17 to allow the return of part of the gases in the pipe to the combustion chamber. In a modification, the cylinders have a common head on which are mounted the delivery valves 17, the combustion chamber, the products-supply manifold, and rotary admission valves to the cylinders.

Title: Circuit arrangement for use with vehicle safety harness
IPC: B60R22/48
Filed: 1971-03-12
Abstract: 1380575 Controlling vehicles JOSEPH LUCAS (INDUSTRIES) Ltd 3 March 1972 [12 March 1971] 6798/71 Heading B7H A starting device for the engine of an I.C. engine of a vehicle is arranged so as to be inoperable unless the driver of the vehicle is occupying the driver's seat and has the safety harness in place. An electrical conductor 15 is associated with the seat 16 and another electrical conductor 20 is carried by the part 18a of a safety harness or seat belt 18, the conductors 15, 16 forming the two plates of a capacitor of which the occupant of the seat 16 forms the dielectric when seated therein. The parts 18a, 18b of the seat belt also carry the two cooperating members of a switch 19 which is closed when the two halves of the seat belt are interengaged. The positive terminal 10 of the battery of the vehicle is connected to an inverter 12 which produces an A.C. output at a frequency of 5 kHz. The inverter 12 is connected to the plate 15 of the capacitor such that when the seat is occupied by the driver of the vehicle a current flows through the capacitor which, if the seat belt 18 is in place with the switch 19 closed, causes a second switch to conduct to energize a relay 29 and so energize a starter solenoid 31 for the vehicle engine. The second switch is a thyristor, the gate circuit of which comprises a transistor. The passenger seat of the vehicle is similarly arranged but the capacitor includes a third conductor situated in the seat and so arranged that if a passenger occupies the seat without the seat belt in place the relay 29 is inoperative irrespective of an occupancy of the driving seat. If desired, the passenger seat may comprise a weight operated switch. The system may include indicator warning lights and/or a buzzer and, if desired, an earthed metal mesh 75 may be incorporated into each seat so that if the seat belt portions are interengaged and laid on the seats behind the driver or passenger the capacitors are effectively earthed.
Patent GB-691641-A (GB)
Title: Improvements in or relating to the production of poly-carboxylic acids
IPC: C07C51/27
Filed: 1951-03-22
Abstract: Polycarboxylic acids (principally mellitic acid) are manufactured by the oxidation of natural or artificial materials rich in carbon, by passing nitric acid into a suspension of the carbonaceous material in sulphuric acid and heating the mixture to 130-230 DEG  C.  The nitric acid may be in liquid or vapour form, and in the latter case is advantageously mixed with a carrier gas, preferably an oxygen-containing gas such as air.  The polycarboxylic acids may be isolated by filtering the hot reaction mixture to remove inorganic by-products, and crystallizing the acids by cooling the filtrate.  In examples: (1) nitric acid (sp. gr. 1.4) is led into a suspension of coke breeze in 96 per cent sulphuric acid at 195-205 DEG  C.; (2) the oxidation in (1) is effected at 170 DEG  C.; (3) flotation fusain is oxidized as in (2); (4) coke from mineral oil products is oxidized as in (1) except that the concentration of the sulphuric acid is 90 per cent and the temperature 215 DEG  C.; (5) pitch coke is oxidized as in (4).ALSO:Acid aluminium sulphate is obtained as a by-product in the manufacture of polycarboxylic acids by the oxidation of natural or artificial materials rich in carbon by passing nitric acid into a suspension of the carbonaceous material in sulphuric acid and heating the mixture to 130-230 DEG C.  After separating the inorganic residue from the hot solution of the polycarboxylic acids by filtration, the acid aluminium sulphate, together with traces of other sulphates, may be extracted with water, and any residual silicic acid removed by filtration.  In an example, coke breeze is employed as starting material.

Abstract: 395,652. Cooking and cooling canned goods. FOOD MACHINERY (M. & P.), Ltd., Park, Manchester.-(Food Machinery Corporation ; 337, West Julian Street, San Jose, California, U.S.A.) March 7, 1933, No. 6880. [Class 49.] In cooking and cooling apparatus for canned goods in which star wheels are used for transferring the cans from the cooker to the cooler and in some cases for delivering the cans into the cooker and from the cooler, detector means is provided adapted to be successively projected into and withdrawn from the pockets in the star wheel at a point between the delivery and reception points thereof so that a jammed can will prevent the detector fully entering its pocket. The detector is operatively connected with means for bringing the star wheel and associated moving parts to rest when it encounters an obstructed pocket. As shown, a toothed ejector wheel m ejects the cans from the rotary carrier a in the cooker A into the pockets h of the star wheel f which conveys them to the rotary carrier a of the cooler B. The detector consists of a rotary star wheel n the teeth of which mesh with the pockets h in wheel f. If there is a can jammed in a pocket, the tooth of the wheel n cannot enter and the wheel n, which is mounted on a spindle o carried by arms p, is displaced upwards. The arms are secured together with a cam r on a spindle q, and on displacement of the wheel n the cam r is rotated and engages with a lever s which projects through the casing t surrounding wheel n. The lever s controls a valve u which controls the supply of compressed air to a pipe v leading to a pneumatic cylinder w in which is a piston for actuating a lever x which operates a clutch z between the belt pulley y from which the apparatus is driven and the shaft 5 and speed reduction gearing which rotate the star wheel f and the conveyor means in the cooker and cooler. When wheel f encounters a jammed can, the clutch z is disengaged and a clutch 7 which acts as a brake to bring the shaft 5 and connected parts to rest is engaged. The lever x can also be operated by hand by a lever 8, for restarting or stopping, which is permitted by a vent orifice in cylinder w releasing the air pressure therein. A whistle 10 sounds when compressed air is passed to cylinder w to stop the machine. To prevent loss of pressure when the cooker and cooler are under pressure, the wheel f has spring-loaded split side pieces which bear thereon and the pockets h have spring-loaded plates which bear against the inner wall of the casing i surrounding wheel f.

Filed: 1967-02-14
Abstract: 1,202,713. Electromagnetic switches. JOSEPH LUCAS (INDUSTRIES) Ltd. 9 Feb., 1968 [14 Feb., 1967], No. 7004/67. Heading H1N. A switch for use with the starter motor of an internal-combustion engine has three fixed contacts, the first and second of which are engaged before the first and third are bridged by a resiliently urged contact bridge on an axially movable control rod. Energization of a solenoid not shown, moves two armatures 32, 33 toward a polepiece 13 which forms part of a contact casing 11. The contact bridge 21, which is spring urged against an angled face 18a of an insulator 18 on the rod 15 is first brought into engagement with fixed contacts 24, 25 and then pivots about these contacts until it also engages contact 26. Contacts 24, 25 are in the "low torque" circuit. of the starter motor and contacts 24, 26 in the "high torque" circuit of the motor. A pin 15a on the rod 15 extends in a slot 14a in a sleeve 14 and the backing spring 22 for the contact bridge 21 acts between washers 22a, 23 (the latter being insulating) against the bridge 21 and sleeve 14. The part 33 is coupled to a pinion (not shown) which when the part is moved on solenoid energization engages a toothed wheel to couple the starter motor to the engine. If tooth to tooth engagement occurs the rod 15 is not moved by the part 33 but the part 32 engages the end of the sleeve 14 to close only contacts 24, 25 so that the engine is driven at "low torque" until the teeth engage and part 33 moves to drive the rod 15 and complete the contact movement.
