Abstract: 1,151,716. Clutches; reverse gearing. SPETSIALNOE KONSTRUKTORSKOE BJURO DIZELESTROENIJA-" SKBD ". 13 Oct., 1966, No. 45787/66. Headings F2C and F2D. A clutch unit for incorporation in marine reverse reduction gearing comprises a positive clutch 4, 22 synchronized by a double cone friction clutch 21, the final engagement of the positive clutch being prevented by balking mechanism 34 until the speed difference between the clutch input and output members falls to a predetermined value. The clutch is operated by a pneumatic actuator 39, 40 in a gear-wheel 16 meshing a pinion 17 on the drive shaft 18. The output shaft 19 drives a toothed wheel 30 associated with balk member 34 through pinions 25, 26, 28, 29. Admission of compressed air to the actuator moves rod 39 to the left, this movement being transmitted by a collar 38 and toggle linkages 37 to a pressure disc 3 which, acting through springs 8, engages the cone clutch 21 to rotate shaft 19 and positive clutch element 22. At the same time a second disc 11 carrying the engaging members 9, 10 for the second positive clutch element 2 also moves to the left but insufficiently to effect clutch engagement due to balk members 34 abutting the clutch end casing, until at synchronism the wheel 30 rotates the members 34 about pins 31 clear of openings 12 in disc 11, which is then permitted to continue its movement to the left to engage clutch elements 4, 22. As applied to a reverse gear forward and reverse clutch units are arranged on parallel shafts, Fig. 2 (not shown), and air is supplied through a valve 60 to the actuators 40<SP>1</SP>, 4011 of the respective units through piston valves 49<SP>1</SP>, 49<SP>11</SP>, control valves 48<SP>1</SP>, 48<SP>11</SP> and interlock valves 47<SP>1</SP>, 47<SP>11</SP>, operating so that air can only be supplied to one of the actuators when the other has effected disengagement of its associated clutch. The air supply is also fed via a shuttle valve 50 to servos 51 operating the control lever 52 of the engine governor 53 to ensure automatic maintenance of engine speed during clutch engagement. The lever 52 is also operable by a control handle 54 through a servo 55 and cam linkage 56, 57.

As shown, five pushbuttons PB1-PB5 are connected to a D.C. voltage 4 V and to corresponding ways of a corresponding number of 5-way single-pole switches 3A, 3B and also via OR-gate 4 and delay 7 to the count input of a binary counter 6 which on each count produces an output signal in turn on each of outputs C 0 -C 3 . A reset push-button 5 is connected to reset counter 6, and to reset bi-stable circuits 2A, 2B via OR- gate 12. Enabling inputs of first gate 1A are connected from the first switch 3A and to output C 0  of counter 6. Similarly, inputs of second gate 1B are connected to second switch 3B and to output C 1  of counter 6, but has a further enabling input from the output of the first bi-stable circuit 2A. The output of bistable 2B may operate a door-locking solenoid (not shown), &c. Switches 3A, 3B are set to define the password. If push-buttons PB1-PB5 are now operated in the correct order, gate 1A is enabled by voltages from switch 3A and count zero line C0, changing the state of bi-stable 2A, the output of which, together with voltages from switch 3B and count one line C 1 , enable setting of bistable 2B to unlock the door &c. Push-button switches PB1-PB5 are also connected to an AND-gate 8 to trigger alarm 9 if all five bush-buttons are pressed simultaneously. A further counter 10 has a count input connected to the last output C 3  of counter 6 and a reset input triggered by final bi-stable 2B and, for example, a count three output triggering alarm 11, thereby allowing, in this case, three incorrect attempts before alarm 11 is raised. Push-buttons PB1-PB5 and switches 3A, 3B may be replaced by a telecommunications receiver, the output of which is fed in sequence to the inputs of the gate circuits only when a correct sequence of digital signals is received by an aerial.

Abstract: 1,236,051. Seat belt length adjustment mechanism. O. L.. LINDBLAD. 27 Sept., 1968 [4 Oct., 1967], No. 46049/68. Heading A3V. An apparatus for the adjustment of the length of a vehicle safety belt 2 comprises transport means for initiating pay-out or withdrawal of the belt depending on the pull exerted on the belt and for jamming the pay-out of the belt when there is a sudden excessive pull. The belt 2 passes over a deflecting roller 4 which is pivotably mounted in a lever 8 pivotable about an axis 9. When the belt is pulled out, the lever 8 pivots against the spring 14 to position 8<SP>1</SP> (shown dotted) closing switch 17 and thus letting the drive motor 12 let out the belt. When the pull is relaxed the lever moves to position 8<SP>11</SP>, closing switch 16 so that the motor winds in the belt. When the belt is suddenly pulled, the roller 4 moves up to the position shown in Fig. 4, thus jamming the pay-out of the belt since portions 21, 22 are travelling in opposite directions and are in contact where the belt is trained round the stationary member 6 at an angle of greater than 90 degrees. The motor circuit has a mercury switch 18 which only closes the electric circuit when the level of the mercury is at least approximately horizontal thereby disconnecting the circuit when considerable acceleration or deceleration forces act on the vehicle or when it has turned over. Instead of an electric motor a hydraulic or pneumatically operated motor may be used. Rollers 5 and 7 are provided with roughened coverings 23, 24 to improve the contact with the belt.

Title: Magneto hydrodynamic generator
IPC: H02K44/10
Filed: 1975-11-12
Abstract: The generator has two electrodes (12a, 12b) which are arranged at a distance from one another along the generator channel (18). In the case of each electrode (12a, 12b), an arc is struck between an emitter (42) and a collector (38) which surrounds the emitter, forming an annular gap (52a, 52b). In the case of this arrangement, the magnetic field (B) causes the arc to rotate in the annular gaps (52a, 52b). The load (20, 58) is connected between the emitter of the one electrode and the collector of the other electrode. This arrangement increases the energy level of the gas (16) in the channel (18) and hence improves the efficiency of the generator. <IMAGE>
