Title: Improvements in or relating to locking mechanisms for fluid operated reciprocating motors
IPC: B60S1/12
Filed: 1959-05-26
Abstract: 905,678. Operating windscreen wipers. CURTISS-WRIGHT CORPORATION. May 26, 1959 [May 28, 1958], No. 17961/59. Class 138 (1). [Also in Group XXIX]  A motor M for operating a windshield wiper comprises alternately pressurized chambers C, C<SP>1</SP> for reciprocating a piston P or similar element to impart rotary oscillations to an output member 15, and means P2 actuated by fluidpressure in one of the chambers C<SP>1</SP> for operating a one-way friction brake 28 to move the brake to released position during movements of the member in one direction. Two motors may be provided each operating a wiper blade and connected to an automatic reversing valve and a manual control valve, the reversing valve having fluid-pressure-operated over-centre spring-loaded mechanism for directing the fluid to alternate ends of the cylinders. The piston P of the motor has two heads 8, 9 between which is a rack 11 engaging a pinion 12 on the shaft 15. The shaft is coupled to a stub shaft 17 which slidably receives the piston P2 connected to a collar 34 having slots 35 co-operating with stationary pins 36. The collar is attached to one end of a spring 28 which surrounds a drum 25 on the shaft 17 and a drum 26 on the casing of the motor to which the other end of the spring is attached. In operation, when the chamber C<SP>1</SP> is connected to the source of fluid pressure to move the piston P in one direction, the pressure is also connected to a chamber C2 to move the piston P2 to the right and axially and angularly move the collar 34 so that the spring is unwound slightly to expand sufficiently to permit the drum 25 and shaft 15 to rotate in one direction. If, at the end of the stroke of the piston P, the manual control valve is operated to reduce the pressure supplied to the motor, the valve mechanism is not actuated to reverse the supply to the motor which may then move the wiper blade to a parking position outside the normal operating area. The piston P2 moves to the left upon the reduction in pressure in chambers C<SP>1</SP> and C2 to permit the spring 28 to grip the drum 25 and hold the shaft 15 stationary. If the control valve is not operated at the end of the stroke of the piston P, the valve mechanism connects the chamber C to the supply and chambers C<SP>1</SP> and C2 to a drain. The piston P2 and collar 34 move to the left and the spring 28 contracts, but the rotation of the shaft is in a direction tending to unwind the spring and is therefore not restricted. In an alternative embodiment, the pins 36 are mounted on the collar 34 and engage slots in a stationary sleeve secured to the casing, and the collar and piston P2 are returned by a spring. Specifications 820,704 and 905,677 are referred to.

Title: Improved method of and device for regulating internal combustion engines of the liquid-fuel injection type
IPC: F02D9/00
Filed: 1935-06-22
Abstract: 445,401. Regulating. SCHIMANEK, E., Muegyetem, Budapest. June 22, 1935, No. 17988. Convention date, July 13, 1934. [Class 7 (vi)] A greater degree of flexibility is obtained with engines working with injection of liquid fuel, particularly for vehicles, by varying the maximum quantity of fuel which can be injected in accordance with the varying amounts of air induced at different speeds. This may be continued with a reduction in the amount of air induced when the engine is working at smaller powers with reduced amount of fuel. Fig. 2 shows one form of apparatus in which a centrifugal governor L adjusts a wedge O which acts as a stop to limit the maximum position of a hand or pedal actuated fuel-control lever J. Reduction of fuel and air at smaller powers may be obtained by connecting the air throttle D by an arm A and link B to the fulcrum K of the lever J. In a modification, the wedge 0 is adjusted by the vacuum in the induction pipe, instead of by the centrifugal governor. Fig. 4 shows another form in which the governor 1 adjusts a curved controlling-slide 5 to adjust the fuel-pump control 16, and also acts on the air throttle 11 through a spring link 13 acting in conjunction with a stop 8, which co-operates at its lower end with a lever 7 connected by a link 6 with the slide 5. At starting, the parts are in the position I, with the throttle 11 closed and the pump control 16 adjusted to supply a slightly greater quantity of fuel than is required for idle running. As the engine attains speed, the parts move to the position II with the throttle fully open, as shown in heavy lines. During further increase in speed, the parts move to the maximum speed position III, the throttle being held stationary by the stop 8 and lever 7, while the fuel is adjusted to suit the speed. Any further increase towards the position IV produces a further adjustment of the fuel and a closing of the air throttle.

Abstract: 1,253,383. Increasing adhesion. BRITISH RAILWAYS BOARD. 10 April, 1969 [17 April, 1968], No. 18135/68. Heading B7J. A method of cleaning a rail for a vehicle by means of a plasma torch carried upon the vehicle, wherein electrical power supplied to the torch is varied to increase automatically as the speed of the vehicle varies, makes use of apparatus wherein the plasma torch 2 is in combination with speed-responsive means 1 for providing a signal dependent upon the speed at which the vehicle passes over the rail and regulating means 6 responsive to this signal for automatically varying the power to the torch 2 as the speed varies. As particularly described, the power is varied so that it is approximately proportional to the square root of the speed and to achieve this a function converting means 5 is interposed between the speed responsive means 1 and the regulating means 6. As shown, the speed responsive means is a tachometric generator 1 whose output is substantially proportional to the speed of the vehicle, the function converting means is a function generator 5 whose output is substantially proportional to the square root of the speed and the regulating means is a transductor 6.

IPC: G11B11/11
Filed: 1970-04-16
Abstract: 1,256,215. Magnetic storage devices and Josephson oscillators. MESSERSCHMITTBOLKOW-BLOHM G.m.b.H. 16 April, 1970 [28 April, 1969], No. 18190/70. Heading H3B. A magnetic storage device comprises a layer of magnetic particles 14 supported by superconducting bodies 11, 13 separated by a thin insulating layer 12. The device is accessed by an electron beam, and the A.C. Josephson effect is used to demodulate the beam during readout. Manufacture-In a first method, superconducting layer 13 is placed in a magnetic field adjacent a heated iron or nickel wire. Wire particles 14 are vapour deposited on to areas of the superconductor 13 which exhibit normal conductivity, these areas being the centres of an array of so called "Aprikosov vortices". In a second method the areas of normal conductivity are formed by an incident beam of electrons rather than these centres. The particles form circular rings 15 around each area, Fig. 2 (not shown), each ring constituting a memory position. Writing-To write into a memory position, a strong beam of electrons is directed to a point or points within or adjacent the ring constituting that position. Depending on where the beam is incident, the ring may assume one of five configurations aligned with the magnetic field of the beam, Fig. 3 (not shown), and may therefore store up to five bits. Reading-The insulating layer 12 between the superconductors 11 and 13 forms a Josephson junction through which electrons may tunnel. When a current of less than a critical value is passed through this junction microwaves are generated, their frequency being a function of local magnetic fields. During reading a low energy beam of electrons is passed through the ring, and the magnetization of the ring causes velocity modulation of the beam. This modulation alters the magnetic field associated with the beam, and hence the microwaves produced in the junction have a frequency characteristic of the configuration of the ring. The microwaves are detected by apparatus 20 situated at the side of the junction.
