Filed: 1957-07-02
Abstract: 840,222. Chucks. JACOBS MANUFACTURING CO. July 2, 1957 [Sept. 11, 1956], No. 20847/57. Class 83 (3). A bevel-closing collet-chuck comprises a chuck body 11 having a conical recess 18 in which the collet 19 is moved axially by the flange 28 on a sleeve 27, has a cam member 35 operated by cams 55 for moving the sleeve 27. The sleeve 27, splined at 31 to the body 11, is connected by screw-threads to the member 35, the conical cam surface 46 of which is pressed against the bevelled ends 54 of twelve equally-spaced pins 55 by spring-loaded plungers 48 bearing on the inner end of the member 35. In the open position of the collet, the outer ends 62 of the pins 55 are engaged in a groove 63 in a ring 64, also formed with an outer groove 77 to receive diametrically-opposite rollers 76 (Fig. 2, not shown), carried by a hand-operated yoke lever 66 encircling the ring and pivoted at 67 to a fixed structure 69, e.g. a lathe, to the headstock or spindle nose of which the body 11 is secured as by bolts 14. The ring 64 is moved to the left by the lever 66 to close the collet, the steeply-inclined edge 61, Fig. 4, of the groove 63 camming the pins 55 radially inwardly and moving the member 35 and sleeve 27 to the left. A further inner cam surface 65 on the ring, at a self-locking inclination less than the angle-offriction, e.g. 2¢ degrees, increases the displacement of the pins, the heads 62 of which are bevelled to match the surface 65. Rotation of the member 35 by its key-notches 78 effects initial adjustment of the collet, one of the three circumferentially-spaced plungers 48 entering one of ten spaced pockets 50 in the member 35 to lock the member after adjustment. Lubricant is introduced into the interior of the chuck through a passage 58 (Fig. 3, not shown), in a part 39 of the body 11, which carries the pins 55 and is fixed by screws 42 to the rest of the body. Lubricant may also be fed through the hollow axles supporting the rollers 76. The collet comprises radial jaw-plates 23 bonded together, as by rubber 24.

Title: Improvements relating to dynamoelectric machines
IPC: H02K23/66
Filed: 1955-07-19
Abstract: 794,743. Automatic control systems and coils for dynamo-electric machines. GENERAL ELECTRIC CO. July 19, 1955 [July 20, 1954], No. 20911/55. Classes 35 and 38 (4). In a system for stabilizing the output of a dynamo-electric machine by regulating the field, hunting due to the inductance of the field windings is reduced by modifying the corrective action of the field regulator in accordance with signals from a search winding responsive to flux variations in the core of the machine. In application to a motor-alternator set 12, 13, Fig. 2, wherein the output frequency of alternator 13 is maintained constant with variations in input to the D.C. motor by conventional means comprising a frequency-responsive circuit 17, 18 whose rectified output energizes a winding 22 of a solenoid controlling a carbon pile 27 in series with the shunt field 5 of the D.C. motor 12, a search winding 9 wound on a part of the motor core energizes a second solenoid winding 26 in response to flux variations in the core. Since this second winding opposes the first, the tendency to over-correction, resulting from the slow response to corrective action due to the inductance of winding 5, is substantially compensated. The system may also operate in reverse sense, with the output of D.C. generator 12 stabilized with variations in the input frequency of its A.C. driving motor 13. An amplidyne generator may replace the carbonpile regulator for energizing the field. The search winding 9, Fig. 1, comprises a many-turn shock-resistant coil of fine wire mounted within an insulating collar 6 disposed round a salient pole 2 of the core 1 of the machine between the core structure and an excitation winding 5.

Title: Means for Harnessing Wind Energy
Inventor: STENNER HERBERT ALFRED
IPC: F03D5/04
Filed: 1967-05-08
Abstract: 1,168,314. Wind-motors. H.A. STENNER. May 1, 1968 [May 8, 1967], No.21232/67. Heading F1T. [Also in Division G3] A wind-motor comprises trolleys pivotably linked together to form a continuous band adapted to be driven around a closed-circuit track by the impingement of air currents on sails mounted on rotatable masts on the trolleys, the movement driving transmission means adapted to drive an electric generator. The endless band comprises trolleys 2, Fig.1, joined together by pivotable links 5 and running on a monorail track or, as shown, a double track 1. A chain 4 attached to the trolleys and driven around the inner periphery of the track by their movement is used to drive an electric generator 6, e.g. via a sprocket wheel 7 and a belt drive 8. Each trolley is driven by a sail 3 which is pivotable about a vertical axis by means of a hydraulic servomotor comprising a piston 31, Fig. 5, positioned by a valve 25 operated by a rotatable tube 22. As the trolley 2 moves around the track 1, a cam 17 which rotates once for each time the trolley makes a complete circuit of the track acts through a follower 20 to rock the tube 22 about its axis of rotation whereby the servomotor adjusts the angular position of the sail so that it is always appropriate to the position of the trolley on the track. Where the direction of the wind is substantially at right angles to the direction of travel of the trolleys, the sails may be adjusted so that the action of the wind on those trolleys that are travelling in one direction reinforces that on those that are travelling in the opposite direction. Alternatively, where the wind acts essentially in one direction of travel, the sails may be feathered when the trolleys are travelling in the opposite direction. To allow for variations in wind direction, a number of cams 17, each appropriate to a particular wind direction, are provided. A corresponding number of followers 20 are provided, and the follower appropriate to a particular wind direction is brought into engagement with its cam by means of a solenoid 21. For this purpose, a selector switch 9 operated by a weather vane is mounted on a high mast and connected to trigger mechanisms 10 each of which may comprise a number of lights mounted one above the above on a mast alongside the track. At any particular wind direction, the selector switch 9 lights up a corresponding one of the lights in each trigger mechanism 10. The light activates a corresponding one of a number of photo-cells mounted one above the other on each trolley, thereby causing energization of the corresponding solenoid 21. The wheel 19 may be replaced by a star wheel which is turned through a fraction of a revolution each time it encounters one of a number of strikers 36 mounted on posts around the track. As shown, strikers may be located at, any, five positions around each curved part of the track so that the driving of the cam shaft is confined to those parts of the track where there is a change of direction.

Abstract: 1473750 Motor vehicle engine mountings; suspensions AUTOMOBILES PEUGEOT and REGIE NATIONALE DES USINES RENAULT 20 May 1975 [27 May 1974] 21370/75 Headings B7H and B7D  In a motor vehicle having front and/or rear suspension units 7 connected to the vehicle body through rubber elements 13 and an engine 1 supported by rubber mountings 22, excessive movement of the engine 1 on its mountings 22 due to suspension shocks is prevented by arranging that each engine mounting 22 acts on the body through a variable volume chamber 18 connected by a pipe 17 to a second chamber 15 having a movable lower wall formed by the rubber element 13 of the adjacent suspension unit 7, the chambers 15, 18 and the pipes 17 being filled with an incompressible fluid. Each engine mounting 22 is secured to a plate 21 carried by a rod 20 fixed to a resilient member 19 forming the upper wall of the chamber 18. Each rubber element 13 is bonded to a flange 14 which is mounted on the body and to a sleeve 12 secured on the piston-rod 8 of the shock absorber 7 by a nut 11. A flange 12a on the sleeve 12 co-operates with the rubber element 13 to limit downward movement of the piston-rod 8, and a bead 13a on the element 13 co-operates with a spring seat 10 provided on the rod 8 for a coil spring 6 to limit upward movement. By suitably dimensioning the variable volume chambers 15, 18 and inclining the axes of the engine mountings vertical and angular accelerations produced by road shocks can be made equal for the body and the engine. In a modification the coil springs 6 act directly on the body in parallel with the rubber elements 13 and springs act between the engine and the body in parallel with the mountings 22 so that the variable volume chambers 15, 18 do not carry static loads. In Fig. 5 (not shown) the variable volume chambers supporting the engine mountings are interconnected by a pipe incorporating an adjustable flow restriction. Rubber bags may be located in the variable volume chambers to contain the incompressible fluid. In Fig. 8 (not shown) the invention is applied to a vehicle having leading arm front suspensions with horizontally disposed shock absorbers.
