IPC: B24B3/34
Filed: 1943-03-24
Abstract: 565,284. Grinding cutting-tools &c. KNOWLSON, R. F. March 24, 1943, No. 4787. [Class 60] A grinding-machine for profiling hard tipped cutting-tools, lapping diamonds to desired shape, &c., comprises a non-rotatable lap 5 of soft material, for example, copper, lead, aluminium, bronze, or a plastic material having applied thereto or distributed therethrough an abrading material, for example, diamond dust, carborundum or boron carbide, the lap 5 being mounted on a reciprocating platen 2 slidable on a machine base 1. On the base 1 is a framework 8 carrying a vertically movable slide 9a supporting a slide 9 movable laterally by a hand wheel 10 and carrying a swivelling slide 11 movable as limited by a slot and locked by nuts 13, 14. A swivelling work-carrier 15 for lapping various cutting rakes, which can be rotated through 90 degrees, is mounted on the slide 11 and locked by cams 16 ; the carrier has undercut parts 18 to receive a member 19 on a removable slide 20, to which the work, for example, a machine tool 21, is clamped by screws 22 fitting in holes 23. An adjustable weight 24 on a beam 25 serves to vary the pressure on the work. The lap is moved at each reciprocation of the platen 2 to pass beneath a form roller or plate 27, which imparts to the lap the desired profile ; the roller is mounted eccentrically in a sleeve 28 adjustable angularly by worm gearing 29 actuated by a cam on the platen through a rocker arm and push rod 30 &c., the roller thereby being fed downwards a predetermined amount per stroke of the platen. When a form plate is used, it is pressed down on the lap, against the action of a spring by a cam.

Abstract: 608,113. Agricultural 1 implements. ROADS, H. C. Feb. 15, 1946, No. 4813. [Class 6(i)] [Also in Group XXXII] Relates to draught-pole devices by which a tractor pulls along a plurality of harrows arranged side by side. According to the invention, a harrow pole comprises a relatively long main frame member 1 with a short frame member 2 arranged transversely to it, the long member being provided at its ends with detachable ground wheels 8 which may be transferred to the ends of the short member to reduce the width of the device in transport. In the form shown, the short member, of tubular construction, is provided with a detachable draught link 5 secured in one of its ends 4 by a pin passing through aligned holes in the link and tube. The ground wheels 8 are mounted on short stub axles which are retained in the ends of the main-frame in a like manner. Draught chains 17 connect the harrows 18 with the harrow pole. For transport, the wheels are transferred to the ends of the short member 2 and the draught link is then moved to one of the positions previously occupied by the wheels. Retractable sprags (see Group XXXII) support the device during this change-over.

Abstract: 819,964. Liquid fuel burners. BLOOM ENGINEERING CO. Inc. Feb. 17, 1956 [April 26, 1955], No. 4991/56. Class 75(1) [Also in Group XII] In a burner construction for furnaces with a chamber having an admission means for combustion air and gaseous fuel and a discharge end for the combustion air wherein the chamber is closed by a perforated baffle fastened adjacent the burner discharge end and penetrated by a central fuel feed passage supplied by a fuel admission tube the passage terminates close to the forward face of the baffle and is surrounded at its terminal part by air openings which penetrate the baffle with their axis extending in the direction of the fuel admission tube, the baffle has a flush surface on the discharge side thereof and the openings have length sufficient to direct the combustion air, are radially spaced outwardly of the fuel admission tube towards the baffle periphery and are separated peripherally from each other.

Title: Otto cycle fuel-injection internal combustion engine
IPC: F02D41/32
Filed: 1972-02-03
Abstract: 1371842 I C engine fuel injection FORD MOTOR CO Ltd 3 Feb 1972 5055/72 Heading F1B Fuel is injected directly into the cylinder of an Otto cycle engine during the induction stroke of the piston 11 in accordance with the mass of air entering the cylinder during each cycle. An outwardly opening electromagnetic injector 19, receiving fuel under low pressure, e.g. 100 p.s.i., is energized by a logic circuit, Fig. 2 having inputs 20 to 26. The air velocity and pressure sensors are mounted in the inlet passage 15 and the temperature and humidity sensors may be mounted to be common to a plurality of cylinders. The output signal of air mass flow from the generator 28 is converted to a frequency in the converter 29 and fed to the counting register 30 so that the register accumulates a count representing the mass of air which has entered the cylinder. The fuel velocity and temperature sensors are mounted in the injector 19 or the fuel supply line and the output signal of fuel mass flow from the generator 38 is converted to a frequency in the converter 39 and fed to the register 30 to reduce the count therein. The up count fed into register input 31 is in a predetermined ratio to the down count fed into input 40 for the same mass flow of air and fuel, 1 : 20 for a 20 : 1 fuel air ratio. Gate circuits 32 to 34 connect a respective stage of the register 30 to the pulse generator, to provide low, intermediate and high or infinite mark/space ratios to the amplifier 36 and injector solenoid 37 dependant upon the count in the register. The amplitude of the pulses is sufficiently high to fully open the injector but the frequency is too high for the injector valve to follow so that the rate of fuel injection is dependent upon mark/space ratio, the valve being more fully open the higher the ratio. The gates 32 to 34 are opened and closed by a bistable circuit 41 which is opened when an electromagnetic device coupled to the engine flywheel produces a signal and closed when the air mass flow falls below a predetermined level and after a time delay sufficient to ensure that the cylinder inlet valve is closed. The register 30 may be set to zero by a monostable circuit 45 when the injection is terminated or the count may be retained for the next cycle so that effectively at high engine speeds the fuel injection during a cycle corresponds to the air-flow in the preceding cycle. For a four cylinder engine two logic circuits each time shared between two cylinders may be provided, only air velocity and pressure and fuel velocity sensors being provided for each cylinder. The intake air may be drawn through a water carburetter providing 100% relative humidity. The injector 19 is cooled by the water jacket 9. The air and fuel flow velocities may be measured by flow meters as described in Specification 1127568 or hot wire or hot film anemometers.

Patent GB-581354-A (GB)
Title: Improvements in or relating to the production of artificial filaments
IPC: D01D5/06
Filed: 1945-03-02
Abstract: <PICT:0581354/IV/1> Artificial filaments are produced by extruding a solution of a filament-forming material in a volatile solvent into a chamber containing a mist of a liquid, in which the volatile solvent is soluble and the filament-forming material is insoluble, and they are then passed through a bath containing the mist-forming liquid in which any residual solvent is removed.  Examples of filament-forming materials suitable are cellulose derivatives such as cellulose acetate, propionate, butyrate, acetate-butyrate or cellulose acetate-propionate, or ethyl or benzyl cellulose.  The volatile solvent generally employed is acetone.  An alternative solvent is methylene dichloride.  When a solution of cellulose acetate in acetone is used, the preferred mist-forming liquid is water.  Liquids which may be used instead of water are methyl alcohol and hexane. Preferably, the solution of filament-forming material is heated prior to extrusion.  The spinning solution and the non-solvent liquid and mist may be heated.  In the apparatus shown in Fig. 1, the filament-forming solution passing through the candle-filter 7 is heated by jacket 10, through which steam, hot water or oil is passed, prior to extrusion from the spinneret 8. The filaments 9 pass vertically through the chamber 3, in which the mist is formed, on to a driving roller 15 which rotates in the bath 16.  The filaments pass around the roller 15 a number of times before passing the guide roller 17 from which they are returned to the roller 15 and then passed to a suitable collecting device 19.  In alternative forms of the apparatus the roller 15 is omitted and the filaments pass from the extrusion chamber directly into the bath of non-solvent.
