Title: Improvements in magnetically-operated friction clutches
IPC: F16D27/08
Filed: 1919-10-04
Abstract: 151,478. Walker, M., and Shanks, C. F. Oct. 4,1919. Clutches, friction.-Relates to means for adjusting the relative position of the various elements of magnetically-operated friction clutches, of the type in which the electro-magnet consists of a rotary annular magnet carrying an armature and energized by an annular coil, and in which the friction clutch comprises a friction member mounted between and co-acting with annular friction surfaces on the magnet and armature respectively. The adjustments comprise (1) means for moving the magnet and armature as a whole, relatively to the shaft mounting on which it is carried, to vary the gap between the friction surfaces, and (2) means for centralizing the friction. member in this gap and returning it to the standard position on disengagement of the clutch. In the illustrated construction, the annular magnet A, the coil B, and the armature C are carried by bolts H on a spider D secured to one shaft E. By adjusting the nuts H', the magnet and armature can be moved as a whole relatively to the spider, to vary the gap between the friction surfaces C<1>, D<1>. Studs on the same radial lines as the bolts H, lock the parts in the adjusted position by forcing the magnet against the shoulder formed by the enlarged ends H<2> of the bolts. The armature slides on the parts H<2> to clamp the friction member F between the surfaces C', D<1>, and is restored by springs O. The friction member F is mounted slidably on the other shaft G and is threaded for rigid engagement with a ring of screwed rods L. By rotating any rod the corresponding portion of the periphery of the disk F can be moved axially, and thus centralized in the gap between the friction surfaces and locked in the adjusted position by a nut L<2>. When the magnet is energized, the disk F and rods L are moved axially against the action of restoring springs N. Fixed stops L<3> on the rods ensure that the disk returns to the standard position after displacement.

[Also in Division H2] Slider 22, which is connected to a bread slice carriage, is latched in the toasting position, by engagement of pins 29 and 37 in teeth 32 and 41, respectively. Pin 29 rotates L-shaped lever 30, 33 about pivot 34, simultaneously to move pin 37, on arm 33, to tooth 41 and to open normally closed shorting contacts 3, 7 of heater 13 for bimetal 11. At the same time, rod 24 is urged, by spring 26 acting on washer 27, to close normally open contacts 2, 6 of the main heater circuit. As heater 13 bends bi-metal 11 towards lever 38, adjustable cam 18 contacts member 42 and turns lever 38 about pivot 39 to release pin 37 from tooth 41. Pin 37 falls on to pin 17 and thereby allows sufficient movement of lever 30, 33 to enable shorting contacts 3, 7 to close. The consequent cooling of bi-metal 11 withdraws pin 17 from engagement with pin 37, so that lever 30, 33 is moved by spring 26 to disengage pin 29 and allow the slider to return to its ariginal position. Contacts 2, 6 are simultaneously opened. The toasting period is adjustable by turning cam 18. Immediate manual release of slider 22, during the toasting period, is effected by raising knob 31.

Abstract: 759,141. Automatic temperature control systems. BENDIX AVIATION CORPORATION. Oct. 7, 1952 [Oct. 9, 1951], No. 25145/52. Class 38 (4). In Fig. 1, variations of the temperature of a gas turbine 10 from a desired value are detected by a thermocouple 32, the voltage from which is compared with a direct voltage reference and applied to an electronic servo-amplifier 30 controlling a two-phase motor 20 operating a fuel valve 18 to restore engine temperature to the desired value. To accelerate the engine from a low speed, a direct voltage from a potentiometer 36, serving as the voltage reference, is applied to amplifier 30 as shown. Engine speed increases up to a value at which surge and/or stall would commence. At this speed the voltage from a potentiometer 50 associated with an enginedriven tachometer generator 48 renders a triode valve 56 conductive to change over relay contacts 42 from the position shown to substitute the direct voltage from a potentiometer 40 as the reference for amplifier 30. Acceleration then proceeds at a lower tailpipe temperature without surge or stall up to a speed at which the danger is passed. At this speed the voltage from a potentiometer 52 associated with tachometer generator 48 renders a triode valve 70 conductive to change over relay contacts 62 from the position shown to restore contacts 42 to the position shown and hence restore the original voltage reference from potentiometer 36 to amplifier 30. Acceleration then proceeds at the higher tailpipe temperature until the desired speed is reached. The speeds at which engine temperature is changed and the value of the lower engine temperature are made dependent on inlet air temperature by a bellows 86 which adjusts potentiometers 50, 52 and 40 in accordance with ambient temperature.
