Filed: 1920-09-07
Abstract: 171,813. Rogers, F. H., (Walker Motor Car Specialties Co.). Sept. 7, 1920. Guarding against unauthorized use.-The steering-wheel of a motor-vehicle may be locked to its steering-tube by projecting a bolt 20 contained in a lock casing 13, secured to the tube, into engagement with a collar on the steering-wheel hub. The lock casing is provided with a cover 35, adapted to conceal the means securing the casing in position, and to be removed only when the steering-wheel is unlocked. As shown in Fig. 4, the collar comprises semicircular parts 4, 5, drawn together by screws 8, the shanks 9 of which are afterwards removed. One or both of the parts have internal serrations 6, and the part 5 has apertures 11 in which the locking-bolt may enter. As shown in Fig. 5. the locking-bolt 20 is held in its locking position bv a lip 29 on a spring-pressed latch 27 pivoted at 28, and may be released therefrom by turning a plate 33 which turns the latch 27 and displaces the lip 29 from the notch 31; a spring 24 then retracts the bolt. The plate 33 is turned 'bv a key 47, Fig. 2, entered in a. barrel lock 34. To remove the cover, the plate 33 is turned in the opposite direction until a lip 37 on the plate contacts with a member 43 on a spring-pressed latch pivoted at 44 on the cover, thereby withdrawing the lip 42 from engagement with a lip 43<1> on the casing and freeing the cover. When the bolt 20 is in locking position, a shoulder 25 thereon limits rotation of the plate 33 and prevents contact with the member 43. The cover is replaced by placing the slot 39 over the flange 40 and pressing the other end until the lip 42 springs over the lip 43<1>. The lock casing comprises two parts 13, 14 provided with gripping-pins 15 and drawn together over the steering-tube by screws 17, the ends of which are enclosed by the cover.

Abstract: 230,750. Franchetti, A. April 10, 1924, [Convention date]. Filters.-In a fuel injector for an internal combustion engine, the fuel on its way to the spraying point is filtered by passing it through a narrow annular passage between a central valve guide b and the casing a. Two parallel screw threads, or groups of screw threads, are cut upon the outside of the guide b, the upper ends of one groove or set of grooves thus formed being connected to a fuel supply pipe e, whereas the lower ends of the other groove or set of grooves are in communication with the space surrounding the spraying valve. The fuel can only pass from one groove or set of grooves to the other by issuing through the narrow annular space surrounding the guide b, this space being sufficiently small to act as a filter.

Title: Magnetic tape transport having variable torque constant drive motor
IPC: G11B15/58
Filed: 1975-06-18
Abstract: 1506637 Magnetic tape transports AMPEX CORP 18 June 1975 [1 July 1974] 25982/75 Heading G5R [Also in Division H2] A magnetic tape transport has tape reels (12), (14), Fig. 1 (not shown), driven by respective electric motors 132, 134, an electric motor driving a capstan (20) at a first speed during intermittent transducing operations and at a speed greater than the first speed during fast rewind, tape buffer loops 110 and a magnetic head (22), at least one of the capstan and reel drive motors including a wound field to produce an adjustable component magnetic field flux and an adjustable motor torque constant (i.e. torque/armature current) in the respective motor, and a motor control circuit variably energizing said wound field so that said respective motor has a first torque constant for tape transport during transducing operations and a second torque constant substantially less than the first for fast rewind operations. The capstan remains in contact with the tape during rewind and the capstan and reel motors are reversible. All three motors may be of adjustable torque constant type, the adjustment being made by varying the current flow in the field winding of a conventional motor, for example. Alternatively, each motor may comprise a wound or permanent magnet field member (82), (90), Figs. 5, 6 (not shown), giving a constant magnetic field component and a wound second field member (84), (92) supplied with current at selectively either of two magnitudes, or in either of two directions, the two field members being associated with the same (86) or with respective armatures (74), (76). Use of permanent magnets facilitates dynamic braking. The motor control may include circuits (150) or (220), Figs. 9, 11 (not shown), which in response to a REWIND control signal produce a gradual transition between the two values of torque constant by gradually changing the current in the second field member from one to the opposite direction. A time delay circuit or reel speed sensing means may be used to ensure that the transition does not start until the tape speed is somewhat higher than the normal transducing speed, whereby in a change from STOP to REWIND, for example, the high torque constant is used to accelerate from stop to said somewhat higher speed. The reel motors 132, 134 are energized via reel drive circuits 136, 138 each including a tachogenerator 144 providing a feedback signal to a pre-amp 140. A servo logic circuit 125 controls buffer chamber vacuum supply 128, reel motor drive circuits 136, 138 and the motor field winding control 130. Tape loop point sensors 116, 117, 118, 120, 121, 122 and linear photosensors 112, 114 in each buffer chamber 110 supply inputs to logic 125. Servo logic 125 is coupled to motion logic 124 (detailed in Fig. 12 not shown) which is connected through an interface 126 to data processing equipment and other sources of external commands.
