Pneumatic and like springs.-Relates to shockabsorbers for vehicles in which a main piston 3 adapted to reciprocate within a casing or cylinder 2 and cushioned by a helical spring 20 therein is provided with an inner chamber 28 forming an auxiliary cylinder in which an auxiliary or pump piston 34 secured, as by a hollow rod 17, to the upper end of the cylinder 2 is adapted to compress fluid drawn into it from the cylinder 2 past a non- return valve 51. According to the invention, the auxiliary piston 34 is provided with an extension adapted to enter an oil well 46 at the bottom of the chamber 28, free communication being allowed between the lower side of the pump piston and the piston rod 17 for normal displacements, but such communication being restricted by the entrance of the piston extension into the well when excessive movement takes place. The piston 34 divides the chamber 28 into two chambers 29, 30 of which the upper one 29 is closed by a member 33. The upper face of the member 33 forms an annular chamber for holding lubricant, which drips into the chamber 29 past the ball valve 51 and thence past a ball valve 56 in the piston 34 into the chamber 30 where it collects in the well 46. The rod 17 has an axial bore 34<a> communicating with transvense ports 35 at its upper end and with a check valve 38 at its lower end. When excessive movement of the main piston 3 causes the rod 17 to enter the well 46, oil is pumped therefrom through the bore 34<a> to the upper part of the cylinder 2, the chamber 30, at the same time, being closed to form an air-cushion which checks the movement of the piston 3. The cylinder 2 is pivoted to the vehicle chassis at 10 and adjustably connected thereto by a rod 11, the main piston 3 being connected to one end of the vehicle spring 49.

Title: Means for surveying bore-holes and strata revealed thereby
IPC: E21B47/022
Filed: 1936-06-03
Abstract: 467,130. Borehole surveying. HUM. PHREYS, F. June 3, 1936, No. 15492. Convention date, Sept. 12, 1935. [Class 97 (ii)] Relates to instruments for indicating the inclination and orientation of the bottom of a borehole and for making a directionally indicative mark on a piece of bore core in situ in the borehole. As shown, a casing 16, carried between compression springs 14, 15, in an outer casing 2, supports on pivots 23, 25 a clinometer cage 7 and in gimbals 32 a compass card 31. The clinometer cage has a biassing weight 26, which swings it into the vertical plane containing the borehole axis, and carries on a pivot 28 a pendulum 27 at the lower end of which is a pointer 29 swinging over a transparent curved scale 30 arranged over the compass card 31. A magnetic needle 33 is pivoted over the compass card which is prevented from rotation relatively to the outer casing 2 by a pin and groove connection 17, 18 between the casings 16, 2. A directionally indicative mark is made on a flat surface ground on the bottom of the borehole by a diamond 10 on a finger 11 pivoted at 12 to the bottom of the casing 2 and urged downwards by a spring 13 so that the diamond is moved radially on the bottom face of the borehole by the weight of the instrument. The indications of the pendulum 27 and magnet 33 are photographically recorded on a sensitive sheet 34 by a lamp 21 the circuit for which is closed by a time switch 19. In a modification the clinometer cage and pendulum are replaced by a bob hanging by a thread so that when the instrument is vertical it lies over the centre of the compass card and when inclined moves over concentric graduations on the compass card. The device shown in Fig. VII enables the core, after it has been extracted, to be placed in a position corresponding to that which it occupied in situ. The core 39 is clamped in a holder 40 which is rotated on the horizontal pivot attaching it to the vertical standard 43 in accordance with the inclination of the bore-hole. The standard 43 is carried at one end of an arm 44, which is rotated on the pivot attaching it to the centre of a horizontal circular scale 45 in accordance with. the orientation of the borehole. A glass plate 59 marked with a line 60 and carried by a plate 58 facilitates the orientation of the core about its own axis in accordance with the position of the mark 41 and enables the dip and strike of strata in the core to be determined. The plate 58 carries a protractor 62 from the centre of which hangs a pendulum 61 and is connected by links 57, 56 to a spindle 53 rotatably mounted on the top of the standard 43.

Filed: 1973-04-02
Abstract: 1432237 Automatic gain control ENTREPRISE DE RECHERCHES ET D'ACTIVITES PETROLIERES (ELF) 2 April 1973 [20 April 1972] 15747/73 Heading H4R The gain of an incrementally variable amplifier is automatically controlled to maintain a predetermined half-wave of a recurring analogue signal between preset limits. The system is is used in borehole sounding in which it is desirable to maintain a particular half-wave of one of three detected waveform patterns between predetermined limits for optimum recording without saturation. The amplified input 1 is fed to a threshold circuit 3 containing comparators (7, 8, Fig. 2<SP>1</SP>, not shown) and flip-flops (9, 10) to detect whether the input lies between the predetermined limits and to supply input signals to logic circuit 4 comprising AND gates (11, 12) respectively feeding advance A and decrease D controls to a register 5 each of whose stages controls a relay to adjust the gain of the amplifier 1. The stage outputs are also fed back to the AND gates 11, 12 in logic 4 to prevent them attempting to increment the register beyond its limits. The circuits 3 and 4 are enabled by the outputs of comparator 40 which compares two preset numbers or number series with the output of a binary counter 37, and receiving an advance-by-one command from monostable 36 whenever the amplified signal 1 is detected in 35 on attaining values either side of zero. The circuits 35-37 thereby effectively count half-cycles of the input signal. The binary counter 37 and threshold circuit 3 are both enabled by a sync. signal S (not detailed) via delay 38 and monostable 39, and the counter is reset by the comparator 40 output when maximum count is reached.

A speed governor comprises a rotating tubular member 12 enclosing a sleeve 13 which houses a spool valve 17 formed integral with a piston 30. A further sleeve 14, 15 has an orifice 40 the flow through which is controlled by a screw 48 carried in a member 42 supported by a leaf spring 43. Member 42 is counter balanced by a similar member 47 supported by a leaf spring 46. In use, pressurized fluid passes to orifice 40 via port 39 in sleeve 13, annular space 36, throttle 34 defined by spool valve 17 and sleeve 13 and passage 37, 38. If the speed increases above the set value, movement of member 42 lowers the pressure in chamber 38 and the spool valve moves to the left until the throttle 34 restores the pressure balance across piston 30. Such movement of the spool valve connects the left-hand side of motor M to a supply line 24 and the right hand side to exhaust via port 22. The motor M then performs the required control to reduce the speed of the engine driving member 12 which, as shown, is a ram air turbine the speed of which is controlled by varying the pitch of blades B.

Title: Hydraulic clutches
IPC: F16D31/08
Filed: 1943-09-27
Abstract: 573,669. Hydraulic clutches. THOMAS, A. N. Sept. 27, 1943, No. 15822. [Class 69 (ii)] A hydraulic clutch comprises driving and driven shafts 28, 32 operatively connected to a pump, and a valve 70 which controls circulation of fluids of different densities, e.g. oil and air, either individually or in mixture through the pump. The latter comprises sun and planet gears 46, 47 carried respectively by the driven and driving shafts and housed in a casing 23 partially filled with liquid. An axially slidable control valve 70 co-operates with pump inlet and exhaust passages 67, 68 and has a central chamber bounded by walls 70c, 70D which extend into close proximity with the shaft. Thus, when the drive shaft rotates and the liquid forms a circumferential ring, air only has access to the chamber. In the position of the valve shown, air only is admitted to the pump inlet passages 67, and shaft 32 remains stationary. Movement of the valve to the left progressively closes the inlet passages to the air port Z and opens them to oil ports 70G. At the same time the exhaust ports are gradually closed. Finally, exhaust and inlet ports are closed and shaft 32 rotates at the same speed as the driving shaft. Relief valves 74 are arranged on the exhaust conduits and further relief valves 84 open under centrifugal force at predetermined speeds to relieve excess air pressure in the casing.
