Title: System for measuring the rotational speed of an internal combustion  engine and the cam and ignition angle thereof
IPC: F02D41/34
Filed: 1971-12-17
Abstract: 1374440 Measuring ignition timing of I C engines SAAB-SCANIA AB 17 Dec 1971 [23 Dec 1970] 58720/71 Heading G1N [Also in Division G4] The engine speed, ignition angle and cam angle of an internal combustion engine are measured digitally by applying pulses to associated counters 30, Fig. 1, under the control of transducers sensing conditions in the engine. The engine speed is measured by counting a predetermined number of pulses for each rotation of a drive wheel 3 connected to the crank-shaft. This is effected by setting a bi-stable 45 whenever a recess 4 corresponding to the top dead centre position of the piston is sensed by a magnetic transducer 5 to allow pulses to pass from oscillator 27 via gate 24 to a counter 30 until a predetermined number of oscillator pulses have been passed when the output of a counter 38 also receiving the pulses resets the bi-stable. At the end of a predetermined time interval a memory 31 is strobed to read in the count which is decoded and displayed on Nixie tubes, the counter 30 being subsequently reset. The cam angle, which represents the time when cut-out contacts 19, 20 are closed so that a high voltage current can be induced in the ignition coil 21 of the engine, is measured by enabling a gate 26 whilst the contacts are closed to supply pulses from oscillator 29 to the counter 30 which is similarly read out for decoding and display at the end of the time interval. The ignition angle which is the angle between the top dead centre position of the piston and the angle at which the contacts 19, 20 are closed is measured by setting a bi-stable 39 when the contacts close to pass pulses from an oscillator 28 via gate 25 to a third counter 30, the bi-stable being reset by the output of transducer 5 sensing the recess 4. The counter 30 is similarly read out and displayed. This measures advanced ignition. A sensing circuit may be included between the bistable 39 and gate 25 so that if retarded ignition is sensed the gate is enabled by the top dead centre position pulse and closed by the ignition pulse, a lamp being additionally lit. The frequency of the pulses from the oscillator 28 is divided by an amount dependent on the engine speed In a modification Fig. 3 (not shown), pulses are fed via gate 25 to the counter 30 between the ignition pulse and the top dead centre position pulse but the transfer is effected to the memory at a time determined by the transducer sensing the top dead centre position. Simultaneously pulses from the oscillator 28 after division by 360 are counted in a further counter which is read out after the same time interval to a memory. The ignition angle is then obtained by dividing the contents of the memory and decoding and displaying the quotients so found. Modification: The ignition pulse may be inductively sensed and the top dead centre position optically sensed by reading a reflective mark.

Abstract: 1,201,583. Swivelling winches. NORTH AMERICAN ROCKWELL CORP. 20 Dec., 1968 [9 May, 1968], No. 60786/68. Heading B8B. [Also in Division F2] A cable handling winch for towing an underwater sonar detector, comprises a cable storage reel 14 mounted on a towing vehicle 40 via a pedestal 12 and an assembly permitting the reel to be angularly movable about two axes A,A<SP>1</SP> and C,C<SP>1</SP> to facilitate alignment of reel with the tow. The said assembly comprises a base 26 motor driven for rotation about the vertical axis A,A<SP>1</SP> and a yoke 41 motor driven for rotation about the horizontal axis C,C<SP>1</SP>, the reel also being axially movable relative to the yoke 41 by means of a motor. A retrieval arm assembly 16 is mounted for motor-driven rotation about the reel axis and comprises at its free end a motor-driven screw arrangement for guiding the cable in regular layers on to the reel, a dual cable drive roller system, Fig. 6 (not shown), and a pair of receiver shells for storage of the sonar detector, the two arms of the assembly 16 being formed by shockabsorbing rams. The dual cable drive roller system comprises two pairs of opposed spring- loaded motor-driven rollers, each pair being spaced longitudinally of the cable which passes between opposed rollers for hauling in and paying out operations. Between the two pairs of rollers is arranged a cable gripping unit which locks the cable for high-speed towing. An idler pulley downstream of the drive roller system is provided with pockets to secure joints in the articulated tow cable, whereas the drive rollers are depressed against their spring loading to facilitate the passage of a joint therebetween. In operation the reel drive and the roller drive system are automatically controlled by load sensors, the roller drive system providing the main hauling force while the reel merely stores the cable, the spring force in the drive rollers is set to cause cable slip at a pre-set load which causes the shock-absorbing arms of the assembly 16 to expand. Rotation about the axis C,C<SP>1</SP> is automatically controlled by a roll sensor and rotation about the axis A,A<SP>1</SP> is automatically controlled by a tracking sensor. The rotation of the assembly 16 is dependent on the cable tow load and the angle at which the cable leaves the assembly, and movement of the reel along its axis for installation and clearance purposes is effected direct from a control panel.

Title: Actuator system
IPC: F15B18/00
Filed: 1971-12-30
Abstract: 1345589 Hydraulic control circuits SUNDSTRAND CORP 30 Dec 1971 [11 Jan 1971] 60871/71 Heading F1P A drive shaft 20, 22 is driven by a pair of hydraulic motors 39, 40 each of which has a separate hydraulic supply provided with a valve 52 for controlling the supply of fluid to the associated motor and a valve 60 for controlling fluid communication between the motor inlet and outlet, the arrangement being such that when the supply valve 52 is actuated the valve 60 prevents fluid connection between the motor inlet and outlet unless the fluid pressure in the circuit fails, if this occurs the inlet and outlet are connected so that the motor freewheels whilst the shaft is driven by the other motor on its own. Both the valves 52 are operated together by a rod 175 rotated by a lever 44 which is moved in an appropriate direction to extend or withdraw aircraft flaps which are controlled by the shafts 20, 22. A mechanical feedback from shaft 20 returns the operating mechanism when the limit of rotation of the shaft 20 is reached. Switches 198, 199 indicate these limits. The shaft has a brake 160, 162 which is applied by Belville springs 165 and released by hydraulic pressure from either one or both of the circuits acting on cups 166, 172 which compress the springs. In operation both on electrical signal and a mechanical signal are required to operate the circuit. Actuation of a solenoid valve 50 under manual control supplies fluid to actuate valve 60, a shut-off valve 62, brake valve 64 and the servo-assist in the selector valve 52. Manual operation of the valve 52 permits flow to the motor 40 and determines the direction of flow. The valve 52 is closed by the feedback mechanism and the valve 50 is closed by one of the limit switches 198, 199. In the event of failure of the supply pressure in either system the other can operate the drive shaft whilst the inoperative motor free-wheels.

Abstract: 698,886. Calendars. THORBURN, H. C. June 1, 1951 (Aug. 15, 1950], No. 20224/50. Class 106 (iv). A perpetual calendar comprises a slide bearing date figures, Fig. 1, which is set to display the calendar for any desired month through an aperture in the front of a frame in which the slide moves, the day names being printed on the frame adjacent the aperture. To determine the setting, a "century number" is first calculated by finding the remainder left upon dividing the number of hundreds in the century by 4 (e.g. the century number for 1953 is 3, the remainder upon dividing 19 by 4). A second smaller slide is also provided in the frame and carries upon its back the century numbers which show through an aperture in the back of the frame and on its front a cross which is seen through an aperture in the front of the frame adjacent the date-figure slide. On the back of the slide is a fixed table of year numbers, Fig. 2. The century number (e.g. 3) in the small slide is set against the column containing the year number (e.g. 53). The date-figure slide, Fig. 1, is then moved so that the name of the required month (the month names being printed as shown on the said slide) is over the cross on the front of the small slide, the desired monthly calendar (e.g. Jan. or Oct., 1953) then showing in the front aperture of the frame. Provision is made for leap years.
