Title: Improvements in and relating to internal combustion engines and the formation and supply of working charges thereto
IPC: F02B3/00
Filed: 1941-09-11
Abstract: 551,859. Two-stroke and four-stroke engines ; materials for actuating. FEHLING, H. R. Sept. 11, 1941, No. 11667. [Class 7 (ii)] Liquid or gaseous fuel and a combustionsupporting agent consisting of oxygen or oxygen-enriched air from a liquid source are admitted to the engine cylinders in proportions so adjusted that substantially incomplete combustion takes place. The engine may work on a constant-volume or constant-pressure cycle. The exhaust products, consisting mainly of carbon monoxide and hydrogen, may be employed for the operation of a secondary engine or for steam generation or other chemical or industrial purposes, in conjunction with gaseous or liquid air or oxygen, or a residual charge remaining in the cylinder may be compressed to assist ignition when the fuel and combustion agent are injected. In an engine working on a constant-pressure cycle, Figs. 3 and 4, the engine cylinder A is provided with a sleeve valve B controlling the exhaust port E and reciprocated in such a manner that a point thereon moves in an elliptical path. Liquid or vaporized fuel is admitted through ducts D<SP>2</SP>, D<SP>5</SP>, D<SP>4</SP> and oxygen through a duct D<SP>1</SP> to an injection device D comprising an injection valve D <SP>3</SP> actuated through a lever D<SP>8</SP> and an atomizer plate D<SP>6</SP>. The cycle comprises alternate power and exhaust strokes, the residual exhaust being compressed in the latter part of the exhaust stroke. In a constant-volume form, Fig. 5, in which the oxygen is admitted through a pipe F<SP>1</SP> and fuel through a pipe F<SP>2</SP>, fuel ducts F<SP>4</SP> in the valve seat are controlled by a valve F<SP>3</SP> actuated through a tappet F<SP>6</SP> and ignition is effected by a spark plug. The oxygen or oxygen-enriched air in liquid form is supplied by a pump H, Fig. 6, from an insulated reservoir G to a gasifier J comprising a coil J<SP>1</SP> in a heating jacket J<SP>2</SP>, and thence at T<SP>5</SP> to the engine. In both forms, the charge supplied to the engine is controlled by the thermodynamic state of the combustion-supporting agent or by timing the operation of the inlet valve or nozzle. The exhaust gases may be used as fuel in a secondary engine working on a similar cycle, or to act upon a trunk piston or in a supplementary cylinder in the main engine. The secondary engine may work on a four-stroke cycle, the products from the primary engine being admitted during the first stroke and oxygen or oxygenenriched air being injected towards the end of the following compression stroke. Some air may also be admitted with the products during the induction stroke. Instead of exhaust products, the secondary engine may employ water gas, town gas, coke oven gas, or natural or oil gas in conjunction with oxygen or oxygenenriched air from the liquid source.

Title: Anti-creep brake system
IPC: B60T8/00
Filed: 1971-04-29
Abstract: 1335924 Anticreep brake system FORD MOTOR CO Ltd 29 April 1971 [22 June 1970] 12031/71 Heading F2F An anticreep brake system for a motor vehicle has a solenoid operated valve located between a master cylinder and front wheel cylinders to trap pressure in the wheel cylinders and is controlled by a speed sensor developing a signal proportional to rear wheel speed and a throttle pedal position signal developed when the engine throttle is open to provide a lower speed trip at which the brake system is actuated as the vehicle decelerates to rest and an upper trip speed point at which the system is released during acceleration of the front wheels. The speed is detected by means of a toothed wheel 10 and inductance coil 12 connected to an amplifier transistor 22, through resistor 25. When the base of transistor 22 receives a positive signal the collector circuit comprising source 28 and resistor 30 conducts causing a square wave signal to pass to transistor 32 which acts as switch for the speed detector. When transistor 32 is non-conducting an 8- volt source 42 charges capacitors 36, 54 of the speed detecting circuit. When the input signal to the base of transistor 32 is low, capacitors 36, 54 have sufficient time to develop charge causing the speed detecting circuit to be triggered and the speed at which this occurs is a lower trip point. When the brakes are applied switch 76 in the brake light circuit closes connecting the base of a transistor 62 to a 12 volt source 78 through a connector 80 and controlled by resistors 82, 84. The 12 volt supply is applied to a capacitor 86 to maintain bias on the base of transistor 62 once the brakes are applied making it impossible for the speed detector to be actuated when the speed falls below the lower trip point. If the driver depresses the engine throttle switch 92 closes connecting the base of transistor 58 to the 12 volt supply causing current to flow through the collector. The 12 volt supply passes through a line 94 to reverse bias transistor 130, Fig. 26 (not shown) which is thereby turned off together with a transistor (100). This turns off a transistor 134 and deactivates relay coil (136) controlling the solenoid valve. The voltage at a point 90 and the base of transistor 62 is reduced. Transistor 62 stops conducting as transistor 58 is turned on and point 56 becomes grounded dissipated charge that may have accumulated in capacitors 36, 54. Point 56 may also be grounded through a door ajar switch 96 closed when door is open. Hence capacitor 56 cannot charge and the system is not actuated when the door is ajar.

Filed: 1941-09-20
Abstract: 552,160. Treating textiles with liquids. BRITISH CELANESE, Ltd. Sept. 20, 1941, No. 12193. Convention date, Jan. 9. [Class 15 (ii)] [Also in Group VIII] A compact braid is obtained by braiding non-thermoplastic yarns about a core yarn of thermoplastic material and bonding the covering yarns with the core. The non-thermoplastic yarns may be made from cotton, linen, silk or regenerated cellulose. The regenerated cellulose may have been stretched and completely saponified. The core may be made of an organic ester of cellulose, e.g. cellulose acetate, or a mixed ester, e.g. cellulose acetate-propionate, or a cellulose ether, e.g. ethyl cellulose. Alternatively the core may be made of a synthetic linear condensation product, e.g. the polyamide products derived from diamines and dicarboxylic acids. Before braiding, a plasticizer may be applied to the core yarn either by dipping, spraying or by passing the yarn over a roller immersed in the plasticizer, e.g. dimethyl phthalate. Such a plasticizer may be a solvent for the yarn at higher temperature, but may have no solvent action at ordinary temperatures. The core yarn, with or without the plasticizer, with the non-thermoplastic yarns braided about it may be passed through a bath containing a liquid capable of a softening or solvent action upon the core. The liquid may be acetone, aqueous acetone, or mixtures of acetone and methyl or ethyl alcohol.

Class 79(5) Steering mechanism for a mechanically propelled road vehicle having independently sprung steerable road wheels includes an element 10, 5, Fig. 1 whose longitudinal axis is perpendicular to its pivotal axis about which it makes a restricted angular displacement during steering and which is continuously urged to the straight-ahead position by a spring 17 and/or 17a. As shown in Fig. 1 the steering gear for independently suspended wheels 7c comprises a gear box 3 actuated from a column 2 from a hand wheel 1, the rocker shaft 4 of the gear box carrying a drop arm 5 connected to one steering arm 7a by a link 6 and an extension 10 of the arm 5 being conected to the other steering arm 7a by a track rod 12, a lever 14 pivoted at 15, and a link 16. The joints between the link members of the gear are universal joints. The extension 10 of the arm 5 is connected by a tension spring 17 to a bracket 18 on the chassis frame 8, the spring being tensioned as the gear is moved from its straight-ahead position. Alternatively or additionally a spring 17a may be arranged between a bracket 18a on the frame 8 and the end 13 of the lever 14. In a modification., Fig. 3 (not shown), the bracket 18 is replaced by a short rod arranged transversely of the vehicle, the spring 17 being connected to a member slidable on the rod, the arrangement being such that the loading is not so great in the full lock positions compared with the embodiment shown in Fig. 1. In another modification, Fig. 4 (not shown), the bracket carries a slot whose radius of curvature is the end of the extension 10 in the straight-ahead position, the spring being attached to a pin and roller device slidable in the slot, and the arrangement being such that the spring loading is less in the full lock positions than that with the embodiments in Figs. 1 and 3. In a further modification, Fig. 5, the extension 10 is cranked relative to the arm 5 and spring 17 interconnects the extension 10 and the steering column 2. In further modifications one end of the spring 17 is anchored directly to the drop arm 5 instead of to the extension 10.

Filed: 1918-07-30
Abstract: 130,453. Tibbals, W. H., and Endfire Extinguisher Co. July 30, 1918. Piston apparatus for discharging receptacles.- Relates to fire-extinguishers of the type comprising a container for fluid, having a discharge valve, and an axially movable piston operated by means of a screw, a hand-operated member being provided for operating the piston and opening and closing the valve in advance of the movement of the piston. A crank 40, having a handle 51 hinged to it, actuates the screw 12 through bevel gearing 30. The handle is provided with a locking pawl 56 for retaining it in the operative position, and lugs 55 which in the inoperative position engage a lug 54 in the casing and thus prevent rotation of the crank. The crank 40 carries a hollow hub 41, journalled on the exterior of a screwed collar 37 and provided with a short internal thread 42 engaging the threads of the collar 37, so that on rotation the hub 41 slides outwards into the position shown in dotted lines. A groove 46 engages the head 47 of the valve, 43 and' thus opens the port 8<1> leading to the nozzle 8. When the thread 42 reaches the lock-nut 39, further rotation of the crank 40 causes the screw 12 to be rotated through the bevel gearing 30, thus actuating the piston. A sliding pawl 44 normally engages ratchet teeth 45 on the inside of the crank, but may be held out of engagement therewith by means of a handle, as shown. This pawl prevents the piston from being moved in the opposite direction except when desired. The piston comprises a body 10 threaded to receive the screw 12 and provided with externally screwed extensions 13, 16. The upper extension 13 is engaged by a collar 15 which forces a cup-shaped expander 24 against the cup leather 23. The upper part of the collar 15 is screwed to receive a cup 17 which forces a washer 19 against a packing 18. The lower extension 14 is engaged by a cup 16 which forces a gland 16<1> against the packing 21. The piston is also provided with a depending screwed ring 25, upon which screws a ring 26 compressing the packing 27. The bottom of the receptacle contains a valve 5 normally opened by the spring 4' but capable of being closed by the piston abutting against the cap 5<1>, a spring 5" being interposed between the cap and the valve stem. A spring buffer 60 is provided, against which the piston abuts when in the lowermost position.
