Abstract: 1528941 Controlling winches THOMPSON BROS (ENGS) Ltd 24 May 1976 [19 Sept 1975] 38594/75 Heading B8B [Also in Division F2] A winch includes a drum driven from the output shaft 11 of an internal combustion engine through a drive train including a reduction gear-box 25, an electromagnetic brake and an electromagnetic clutch, an electrical emergency stop switch being provided to free the clutch, apply the brake and stop the engine by cutting off the fuel supply. The clutch comprises a clutch disc 12 keyed to the shaft 11  and having friction pads 13 for engagement with a friction disc 18 which is spring biased towards and mounted for axial movement on, a rotatable coupling disc 16. The friction disc 18 is formed from magnetic material and upon energization of an electromagnetic coil 14 in a stationary housing 15, the disc 18 engages the pads 13 against spring bias for clutch engagement. The coupling disc 16 is flexibly coupled to another coupling disc 21 keyed to an input shaft 24 to the gear-box 25. The shaft 24 has a brake disc 26 splined thereto for rotation between brake friction pads 27, 28 carried by a station housing 29 and a movable member 30. The member 30 is slidably mounted on bolts 31 supporting a brake housing 32 carrying an electromagnetic coil 33 which is energizable to draw the brake member 30 away from the brake disc 26 against spring bias. The brake member 30 may be manually released by a lever 35. The electrical control circuit for the winch drive is arranged such that fuel is supplied and. the internal combustion engine is started upon depression of a starter button. The winch drum can then be started or stopped by appropriate depression of start or stop buttons which cause energization or de-energization of the coils 14 and 33 to either engage the clutch and release the brake, or engage the brake and release the clutch. An emergency stop button is provided which when depressed de-energizes the coils 14, 33 and cuts off the engine fuel. An alarm is sounded if the engine stops whilst the fuel supply is still open.

IPC: G01F23/64
Filed: 1958-12-05
Abstract: 866,841. Magnetic switches. TEDDING- TON AIRCRAFT CONTROLS Ltd. Dec. 4, 1959 [Dec. 5, 1958], No. 39313/58. Class 38 (5). [Also in Group XVIII]  In a float - operated switch having a contactcarrying permanent magnet repelled by a second permanent magnet on the float, a magnetic keeper between the magnets causes snap-action movement of the contact carrying magnet. The hollow float 4 is slidable in a perforated tube 3 secured to a body 1 threaded at 2 for securement in a tank. Flexible spiders 9 secured at their periphery by insulating rings 10 clamped to the body 1, carry a cylindrical magnet 8 which is coaxial with and opposed to the magnet 7 carried by the float. A contact ring 14 insulated from and carried by the magnet 8 cooperates with fixed contacts 15, 16, 17 on segments 18, 19 clamped to but insulated from the body 1. A sealed cover 20 encloses the contact chamber which is separated from the tube 3 by a wall 12 of the body 1 and by a thin saturable magnetic keeper 13. The magnet 8 is normally attracted to the keeper 13 and as the magnet 7 moves nearer to the keeper so that the gap between the keeper and magnet 7 becomes less than the gap between the keeper and the magnet 8 (dependent on the thickness of the wall 12), the magnet 8 is rapidly repelled upwards to close the contacts. When the magnet 7 is moved downwards the attraction between the magnet 8 and the keeper ensures rapid contact opening. A ballast chamber 6 on the float 4 may be weighted to set the operating level.

Abstract: 1324211 Power-assisted steering mechanism FORD MOTOR CO Ltd 23 Aug 1971 [29 Oct 1970] 39380/71 Heading B7H Power-assisted steering mechanism comprises a steering shaft 10, a worm shaft 30 co-operating through recirculating balls 80 with a piston 72 forming opposed chambers 86, 90 in a fluid pressure cylinder 70, a valve body 18 connected to the worm shaft 30 and surrounding the steering shaft 10, and a pair of ball valves 126, 126<SP>1</SP> which are actuated by an arm 142 on the steering shaft 10 and co-operate with valve seats 122, 122<SP>1</SP> in the body 15 to control distribution of pressure fluid from an inlet passage 44 to the respective chambers 86. 90. A C- spring 136 encircling the valve body 18 acts on the ball valves 126, 126<SP>1</SP> through stems 134, 134<SP>1</SP> to urge the valves against the arm 142 so that the arm is maintained in a central position and turning of the steering shaft 10 with respect to the body 18 is opposed by a yielding resilient force. Each valve seat 122, 122<SP>1</SP> is formed in a valve member 120, 120<SP>1</SP> which is slidably mounted in a valve retainer 130 and provided with a sealing ring 128 loaded by a spring 132. The diameter of the sealing rings 132 is greater that that of the valve seats 122, 122<SP>1</SP> so that the pressure of fluid flowing from the inlet passage 44 into the valve members 120, 120<SP>1</SP> through inlet ports 138, 138<SP>1</SP> urges the valve members against stops 124 positioned to permit fluid circulation through the valves when the arm 142 is in the central position.

A high power microwave travelling wave amplifier, comprises a plurality of individual magnetrons 13 located side by side and reciprocally coupled, the anodes 2 of the magnetrons being supported by a first plate 1, the cathodes 7 being supported by a second plate 6 the arrangement being such that the anode circuits of the structures on the one hand and the cathodes and the structures on the other each form a bi-dimensional network with polygonal meshes for the delayed propagation of energy to be amplified therethrough, a potential difference being applied between the anode and cathode structures, and a magnetic field is applied in the axial direction of the individual magnetrons. The cathodes may be thermionic but are preferably of the cold emission type, and the plates are preferably of a trapezoidal form with high frequency excitation being applied through an input waveguide 16, the amplified energy being abstracted through an output waveguide 18. The ratio of the lengths of the long and short sides of the trapezoidal plates is preferably equal to the power gain of the amplifier, and an amplified wave front is obtained when the wavelength of the energy being amplified is equal to an integral number of the spacing between adjacent cathodes. A specific example is given with typical dimensions for operation in the 10 cm. band, the arrangement consisting of 25,000 anode rod, and giving an average continuous power of 1 Mw. and a peak power of 50 Mw. with an efficiency the same as magnetrons and amplitrons and the bandwidth the same as a normal travelling wave tube. The anodes 2 and the plate 1 may be cooled with water, Fig. 12 (not shown), and if the output window is not parallel to the wave front lossy material may be provided on some of the anodes to absorb reflected energy.

The springs of each pair are spaced in the longitudinal direction of the vehicle. The invention is characterized in that tilting movements of the bearing boxes in the longitudinal direction of the vehicle experience little resistance since the sleeves 15 are then in torsion to which their resistance is low, but tilting movements of the bearing boxes in the transverse direction of the vehicle are strongly resisted since the sleeves are then under compression and offer considerable resistance. The springs of each pair will thus remain evenly loaded and stressed. Each spring may be replaced by multiple telescopic springs.
