Abstract: A monitor and malfunction detector for the thread feed of a textile machine. The monitor combines electronic information and mathematical analysis of the movement of the thread, including speed, tension and fiber and consistency, thereby permitting the determination of: 1) presence of knots and inconsistencies in the thread 2) the operating status of the textile equipment and thread feed; 3) the prediction of problems based upon the change of operating characteristics including speed, tension, draw and duty cycle patterns; 4) the control of the textile machine being monitored; 5) the diagnosis of mechanical faults; 6) production accounting; and 7) needle burr detection. The monitor also employs a unique signal comparison incorporating differential circuitry, pattern recognition, and averaging functions to achieve these goals efficiently and reliably as well as means to reduce or eliminate the effect of undesirable electromagnetic transients on the operation of the textile machine.
Abstract: An electronically controlled locking apparatus uses a latch, a latch locking clip and a solenoid to lock a circuit pack face plate to an equipment chassis based on activity in the circuit pack. The latch is pivoted so that one end engages the chassis while the other end is locked by the latch locking clip. The solenoid and plunger are deployed so that the plunger can selectively prevent the latch locking clip from disengaging the latch, thereby preventing the latch from being opened. Circuitry for indicating activity on the circuit pack controls the solenoid and plunger, thereby preventing the removal of an active circuit pack. Additional override circuitry permits an operator to override the solenoid should the circuit pack need to be removed in emergencies.

Abstract: A reciprocating laboratory shaker (10) includes a platform (12) driven by a motor (62) which is constrained to move in a reciprocating fashion by a pair of flexible bands (30, 32) located on opposite sides of the platform (12). A frame (24), which preferably supports the drive motor (62), includes a pair of upright supports (28) which are attached to a pair of wide, but thin, flexible plastic bands (30, 32) at least at two locations. Each of the two flexible bands (30, 32) includes a pair of rollers (34, 36, 38, 40) attached to the inside surface (50) of the bands (30, 32). The laboratory platform (12) is attached to the remaining outside face (52) of the bands and is driven by the drive motor (62) having an appropriate crank mechanism (54). The two flexible bands (30, 32) constrain the motion of the platform (12) to substantially a single direction, x, while preventing it from moving in either the y or z directions.
Abstract: A method of locating a concealed conductor is performed by generating a magnetic field with a direction in which the field is a maximum. The magnetic field is rotated until that direction is directed towards the conductor. In this way, a signal is induced in the conductor which has a maximum value when that direction is directed towards the conductor. The induced signal is detected in the conductor, using a detector arranged to determine the direction of the conductor relative to the detector. The detector detects when the induced signal has the maximum value.

Abstract: An electromagnetic drive is described that exhibits two electromagnets (2, 3) situated opposite one another and an armature (10) between them that can be moved back and forth. The armature (10) is held in an intermediate position by elastic forces and brought into a terminal position by the power of the electromagnets (2, 3). The armature (10) is mounted using a torsion spring (6) and at least one drive together with its bearings forms a single structural unit.
Abstract: A magazine and compact feed mechanism for firearms includes an end cap on the magazine to keep cartridges from falling out and a stop mechanism for preventing a rotating cartridge transfer disk from traveling beyond 90°. The magazine is placed in a horizontal position so that it is parallel to the barrel and includes an end cap that is shaped to prevent cartridges from inadvertently falling out of the magazine. A spring-loaded cover may also be added to the magazine for further protection. Cartridges from the magazine are delivered to a rotatable transfer disk by an injector arm driven by the recoil of the slide mechanism. A rotatable cartridge transfer disk is also driven by the recoil of the slide mechanism and functions to receive the cartridge from the horizontal magazine and rotate it 90° so as to present it properly to the breech mechanism so that it can be presented to the barrel.
