Abstract: 942,251. Exciting dynamo-electric machines; alternators. MAWDSLEY'S Ltd. Nov. 30, 1959 [Nov. 10, 1958], No. 36096/58. Heading H2A. The A.C. voltage at slip rings 1, 2 of an alternator driven by a variable speed engine is kept constant over a range of speeds by the opposing effect of field windings 4, 5, fed from battery 10 and commutator 3 of a D.C. armature winding. At slow speeds winding 4 is separately excited from battery 9, no current flowing through winding 5 as relay contacts 20, 23 are open. When the commutator voltage reaches a predetermined value, it energizes relay coil 22 to close contacts 20, 23 and current from commutator 3 flows through winding 5 to flatten the A.C. volts curve and also through winding 4 to reduce the current from battery 9. In a modification the relay may be replaced by a rectifier such that until a predetermined speed is reached the battery alone supplies the field winding. In another embodiment the commutator and -armature winding may be replaced by a transformer and rectifier energized by the A.C. output of the slip rings.

Abstract: 537,000. Variable pitch propellers. REISSNER, H., and ARGUS-MOTOREN GES. Dec. 12, 1938, No. 36185. [Class 114] In a variable pitch screw propeller, means, dependent on the torque exerted on the propeller by the engine controls through a constant speed governor, are provided for controlling the application of forces, which are developed during flight, to a mechanism for changing the pitch of the propeller blades. The governor may also be controlled automatically according to the air density. In the form shown in Fig. 1, the blade root 3 may be rotated about its longitudinal axis by means of gearing 4, 6 and an adjustable shaft 5 carrying a double-sided friction coupling 7 which is engageable with either one of a pair of bevel' wheels 8, 9, when the shaft is moved axially under the control of the weight 14 and spring 15 of a constant speed centrifugal governor. The bevel wheels 8, 9 are driven by a common bevel wheel 10 on the shaft 11 of a boss 12 with air brake blades 13 which rotate independently of the propeller shaft. The governor spring is supported by a threaded member 16 adjustable in a fixed nut 17 and provided with spur-wheel teeth 18 which engage a crowntoothed arcuate rack 19 secured to a flange 20 which is fastened by a thread 21 to the propeller boss 2 and which is screwed to the shaft flange 1. The flange 20 and the boss 2 are also provided with flanges 22, 23 respectively, and rubber washers 24 are secured between the flanges under compression by means of screws 25. The boss 2 rotates relatively to the flanges 1, 20 in proportion to the propeller torque and correspondingly controls the speed governor. For controlling the governor according to barometric pressure, the nut 17 may be connected to a corrugated vacuum tube 27. Fig. 2 shows a similar arrangement embodying an auxiliary blade 38 which is rotatable in a housing part 35, and is given the same pitch as the main and 'lever arms 41, 42. The part 35 is threaded on the body 32 of the centrifugal governor 31 ... 34 and the torque between the two parts 32 and 35 determines the setting of the governor. The centrifugal, governor may be replacd by a similarly acting hydraulic or electric governor.

Title: Improvements relating to pneumatic vehicle-suspension systems and dampers therefor
IPC: B60G15/12
Filed: 1959-10-27
Abstract: 874,003. Controlling shock absorbers. GRANET, C., ROLAND, G. E. R., and CRANE, R. R. Oct. 27, 1959 [Nov. 6, 1958; Oct. 14, 1959], No. 36381/59. Class 108(3). A variable hydraulic damper for use on vehicles having pneumatic suspension has means controlled by the suspension gas pressure for varying the damper resistance. Fig. 1 shows a suspension system with pneumatic bellows 3, 4 and levelling valve 7, incorporating a lever type damper 14 having a pipe connection 20 between the damper and the bellows gas pressure line 9. The damper, shown in Fig. 2, comprises a body 22 with a cylindrical lower portion 24 in which moves a sleeve 28 with a pair of piston heads 30, 32 actuated by a lever 34 attached to shaft 15 which is in turn actuated by the suspension movements. When sleeve 28 is moved to the left fluid from chamber 56 passes through passages 62, 66 past spring loaded variable restrictor valve 78 into the damper body and fluid flows from the damper body through one-way valve 42 into chamber 58. A similar action occurs when the sleeve is moved to the right, fluid flowing through passages 64, 68 past valve 80 from chamber 58 and past non-return valve 40 into chamber 56. The restriction of valves 78, 80 is controlled by cam plate 102 which varies the pressure of valve springs 82, 84 through plungers 86, 88. The cam plate is controlled from rod 120 through mating pin 106 and slot 142 on collar 140 attached to the rod 120. The position of rod 120 is determined by the opposing forces of spring 132, and the suspension gas pressure acting on piston head 112. A bellows type seal 114 is used to prevent the suspension gas from entering the damper body. In operation when the vehicle is loaded 'the suspension pressure is increased moving rod 120 to the left rotating the cam plate 102 against plungers 86, 88 to increase the spring pressure on valves 78, 80 and hence the damping effect. Abutment of piston head 112 on casing 108 limits the reduction of damping effect. By-pass passages 144, 146 may be provided to allow undamped small oscillations. Extended screw plugs 154 may be used to render these passages inoperative.

Shearing.-A face of the bending bar 28 has slots co-operating with guide ribs 43 on a guide block 41, the face terminating in a slotted shearing edge 54 which bends the blank as it shears it over the curved corner (55), Fig. 4 (not shown), of an insert 44 over which the strip is fed through .the block 41. After the shearing operation, the bars 28, 29 come to rest against the adjustable crimping die 14. Wire placed in the die is trimmed by a pivoted blade 53 biased by a spring 51 and operated by contact with the slide 26, Fig. 7 (not shown). Strip feeding.-This is done in steps by rotatable segments 18, Fig. 1, made resilient by slots 19 and driven from the one-revolution clutch. Carriers 12 for the segments 18 are adjustable to provide larger feed steps than necessary so that the strip buckles slightly after striking a stop 45, Fig. 2. Dies.-The end of the punch may be flat or concave with embossing ribs (58), Fig. 7 (not shown). Turntables.-If the wires are fed to the die by an indexable turntable (not shown), the die is retracted during indexing steps.  Crimping.-If longitudinally-ribbed strip is used, producing ribs transverse of the wires, these may cut through insulation on the wires and obviate the need for stripping the insulation
