Filed: 1946-02-14
Abstract: 611,924. Gas-producers; coking processes. STANDARD OIL DEVELOPMENT CO., and ARNOLD, C. Feb. 14, 1946, No. 4684. Addition to 586,391. [Class 55(i)] In the process of the parent Specification some of the heat required in one or more of the gasification zones or all the heat required in one or more but not all of them, is generated by partial combustion of the material therein with oxidizing gas, and the fluidized solid stream is fed into each zone beneath the level of the fluidized bed. Finely ground coal &c. from a crusher 1 is dispersed in a gas such as superheated steam, nitrogen, or combustion gases and passed into a carbonization chamber 5 whence the stream of solids is withdrawn through a pipe 7 and caused by the introduction of an oxidizing gas such as air or oxygen through an inlet 10 to flow into a gasification chamber 9 into which steam, superheated by contact in a chamber 24 with material discharged from chamber 9, is passed. Another stream of discharged material is supplied to chamber 5 through a pipe 11, and part of that passing through chamber 24 may also be returned through a pipe 26 to preheat the initial charge, the rest being discharged through an outlet 27 to prevent accumulation of non-carbonaceous material in the system. Distillates from chamber 5 pass through a cooler 13 and water gas &c. from chamber 9 after separation of dust imparts heat to a steam boiler 16. Oxidizing gas may be added to chamber 5 to generate combustion heat in the chamber, the amounts of hot solids returned through pipes 11, 26 being reduced correspondingly. Sand or other inert material, and also alumina, lime, magnesia or coal of higher ash melting point, to raise the ash melting point, may be added to the coal. Specifications 578,711 and 582,055 also are referred to.

Title: Environmental measuring instrumentation
Inventor: STACEY DAVID STEARNS
IPC: G01F23/60
Filed: 1963-02-06
Abstract: 1,026,625. Electric selective signalling. BALL BROS. RESEARCH CORPORATION. Feb. 6, 1963, No. 4780/63. Heading G4H. A measuring device consists of means for converting the quantity to be measured with a rotational or translational movement of a coded scale, scanning brush adapted to traverse the scale to produce a succession of signals and means for measuring or recording the signals. The device may measure pressure at the bottom of a drill shaft, a helical Bourdon tube 3, Fig. 2, being arranged to rotate the disc C, carrying a monophilic binary scale pattern of non-conductive areas. The body of the disc is conductive and earthed. To obtain a reading voltage is applied to line 4 by closing switch 14. Line 4 connects to a motor 19 and the scanning brush 20, the brush being slidably mounted on a carriage 46 and moved by a cam driven by the motor. In the next position, towards which the brush is urged by a spring it stands on a separate contact 21 connected to earth by a resistor 25. The initial current is determined by the motor 19 and the value of resistors 25 and 27. As the brush moves over the disc the current is determined by whether the brush is contacting an non-conductive portion or is earthed through the disc. One condition produces a lower and the other a higher current than the initial current, the different conditions being indicated on a meter. The carriage is displaced by a cam 39 driven by motor 19. The shape of the cam causes a slow movement in one direction and a fast fly-back, the resulting rapid oscillation of the signal on line 7 indicating that the reading is finished. The external pressure may act on the Bourdon tube through a diaphragm and the brush 20 may be carried on a pivoted arm so as to move on a circular path. The coded disc is modified to accommodate this scan path. In a modification for measuring temperature the disc is rotated by a bimetallic member. In measuring liquid level a float is connected to displace a rectangular code plate, the coded areas of which are scanned by a brush moving normal to the direction of displacement.

Title: Internal combustion engine
IPC: F02D41/34
Filed: 1972-02-03
Abstract: 1371843 Fuel injection systems FORD MOTOR CO Ltd 3 Feb 1972 5056/72 Heading G1N In an I.C. engine operating on the Otto cycle, a logic circuit provides electrical signals representative of the mass of air flowing through the intake manifold to a cylinder of the engine to control the mass of fuel injected at a location downstream of air mass sensing means to thereby a constant ratio of air mass to fuel mass. As shown in Fig.2, sensors 20-23 of air intake velocity, pressure, temperature and humidity are connected to a function generator 28 which provides an electrical signal representing the air mass flow. This signal is applied to a voltage to frequency converter 29 whose output steps up a register 30. Fuel velocity and temperature sensors 25, 26 are connected to a generator 38 which provides a signal representing fuel mass flow to a voltage to frequency converter 39 whose output steps-down register 30. The ratio of the frequencies of converters 29, 39 is approximately 20:1, i.e. the air fuel ratio, for the same fuel and air mass flows. A crank-shaft trigger 24 is provided to initiate injection in each cycle. In operation, when the intake valve to a cylinder opens during the induction stroke, the generator 28 produces a signal which causes the register to step up via converter 29. After a duration, the trigger 24 operates a bi-stable circuit 41 via a monostable circuit 42. The circuit 41 operates one of gates 32-34 depending on the count stored in register 30. Each gate causes a generator 35 to provide different mark/space ratio pulses to operate the injector valve solenoid 37, the different pulses being such that they merely affect the amplitude of opening of the valve. As soon as fuel is being supplied to the cylinder, the mass flow signal from generator 38 causes the register 30 to step down. As the count decreases, different gates are operated to thereby provide decreasing levels of fuel injection, see Fig.5. When the air mass flow signal decreases to a pre-set level, a detector 43 is trig-  gered to stop injection via a time delay circuit 44. The register is reset by a monostable circuit 45. A separate circuit shown in Fig.2 may be provided for each cylinder or alternatively, parts of the circuit may be time shared by more than one cylinder. At high engine speeds it may be necessary to control fuel injection in one cycle in dependence upon the mass flow of air in the previous cycle. The circuit of Fig.2 can be modified for this by omitting the resetting circuit 45 so that any count remaining in register 30 after one cycle is added into the next cycle.

IPC: B60R21/34
Filed: 1920-02-19
Abstract: 163,772. Hancock, H. H. Feb. 19, 1920. Wheel-guards and obstruction-removers.-Relates to life-guards for motor and like vehicles of the type comprising a pair of pivoted arms a, Fig. 2, which are normally open, but are adapted, when an obstacle is encountered, to swing inwards to grip the same. The pivoted arms are connected to a draw-rod h, Figs. 2 and 9, the rear end of which is normally just clear of a pulley y rotated by gearing from the front wheels of the vehicle, but is adapted to be pressed backwards and gripped between the pulley and a roller 24<1> when an obstacle is encountered, the rearward movement imparted to the draw-rod causing the arms a to pivot about their point of connection b. At the end of its rearward movement, the rod h, Fig. 17, presses back a spring buffer 25 and is allowed a small drop which disengages it from the pulley y. During their pivotal movement the arms a are guided by means of a pair of controlling arms q, Fig. 2, connected together at q<1> and having a pin-and-slot connection with the plates t<2> on the arms a. The arms a are normally supported in holders h mounted on resilient extensions m, but are readily released from the holders. The rear ends of the extensions m have a pin engagement with arcuate slots in plates o supported from a fixed fan casing p, and the point of meeting q<1> of the arms q also has a pin and arcuate slot connection with a fixed plate r, the arrangement thus allowing the guard, controlling arms, and holders to move laterally according to the steering movements. For this purpose, a vertical bar v<1>, Fig. 11, connected to the arms q is also connected to the steering arms 7, Fig. 9. During the steering movements provision is also made for keeping in gear the wheels which drive the pulley y. A curved bar z connected at its centre to the draw-rod h and at its ends to the holders k serves to distribute the pressure, whichever pivoted arm a is struck. The draw-rod h is held in its rear position when operated by means of a spring-pressed detent on the vertical bar w, Fig. 11, engaging ratchet teeth x on the draw-rod. When the detent w is disengaged, the buffer 25 presses the draw-rod into re-engagement with the pulley y and the guard can be re-set by backing the vehicle. In order to retain the person or obstacle struck between the arms a, a fan 48, Fig. 25, in a casing p is caused to rotate and create a suction effect when the guard is operated. A projection 29 on the curved bar z causes a wheel on a rotary shaft 31<1> to engage the pulley y, and through gearing 33, 46 the shaft 31<1> rotates two fan blades 48 in opposite directions. In addition, sets of spring arms 53, Fig. 32, operated by cables 50 stretched across the arms a may be projected in front of the person caught so as to prevent him from falling forward. by converging gripping jaws. Reference has been directed by the Comptroller to Specifications 11592/87, 10056/07, 23599/08, 29399/12, and 29996/13.
