Abstract: A method and apparatus for reducing power consumption by a display device includes monitoring time intervals between successive updates by video update circuitry and time intervals between successive uses by one or more user-interface devices, such as a mouse or keyboard. A first time-elapsed signal is generated if a predetermined time interval is exceeded between successive uses by the user-interface devices. A reset input to a first timer is connected to the user-interface devices to restart the timing with each use. A second time-elapsed signal is generated if the interval between successive video updates exceeds a second predetermined time period. Video updating resets the timer used to monitor the video update circuitry, but once the second time-elapsed signal has been initiated, a video update will not disable the signal. Rather, the second time-elapsed signal is latched until the use of a user-interface device.

Abstract: A thermal control system for variable speed microprocessor with a piecewise estimate of temperature change. The estimate is modeled after actual temperature change measurements of a microprocessor operating at low and high speeds and is recorded in a digital format in storage registers, one set of registers for each operating frequency. A counter counts sample microprocessor clock signals for a time over which the microprocessor speed is operating at a specific speed and provides a basic count signal. This basic count signal is incremented or decremented by comparison with stored values of the piecewise estimate of temperature change. As the basic signal increases or decreases, new slopes are provided to the counter for adjusting the basic count, upwards or downwards, depending on whether the system speed is high, intermediate or low. The adjusted counter output is also fed to comparators, which monitor a desired upper and lower temperature limit.

Abstract: A mechanism for producing the bead on a rubber article made by a dipping process first loosens the rubber film on the form using a pair of looseners in the form of roller brushes which contact the lower portion of each form as the forms are moving along on the form carriage. As the forms move along on the form carriage, the looseners move in the same direction as the form carriage but at a different speed, so that the roller brushes roll around the entire circumference of the lower portion of each form to thoroughly loosen the edge of the rubber film from the form. Following the loosening operation, the beads are formed by a separate bead roller mechanism which provides a bead of predetermined dimensions by rolling up the edge of the film a predetermined amount. The bead rolling operation is accomplished by a pair of roller brushes which are mounted diagonally with respect to the direction of travel of the form carriage.

Abstract: An apparatus for continuously transporting and dipping patterns in a process wherein patterns of a desired shape are dipped in and coated with a liquid that subsequently forms a thin membrane thereon. The apparatus includes an endless roller chain assembly that carries a number of pattern carrier assemblies through a linear dipping span. Each pattern carrier assembly includes a vertical track attached to the roller chain assembly and a carrier arm slidably connected to the track for vertical movement therein between a raised position and a lowered position. A pattern support bar is connected to the carrier arm and extends perpendicular to the dipping span of the roller chain assembly. Two or more parallel rows of patterns are suspended from the pattern support bar with their maximum width dimension extending perpendicular to the bar and with the patterns of each row being closely spaced to the patterns of the adjacent row so that at least two rows are transported simultaneously by the same carrier arm.

Abstract: The flexible ball joint is provided with a continuous ring mounted inside a casing and supported by an inner spherical surface of one of the segments of the casing and by a cylindrical portion of an end piece element. The respective contacting sides of the ring are concentric with the juxtaposed spherical and cylindrical surfaces, so that the ring is able to be slidably guided by those surfaces in response to an absorbing shock without losing the contact with the surfaces.

Abstract: A system for performing operations on the edge of an irregularly shaped workpiece, such as seaming the edge of a piece of glass (G) is accomplished by moving the glass (G) along a conveyor (11, 12). The edge of the glass (G) is detected by a camera (13) which makes images of the glass (G). Electronic circuitry (20) receives the image information from camera (13) and determines the location of the edge of glass (G) at a plurality of locations and stores information which is indicative of the entire profile of the glass (G). Additional circuitry (32) receives signals proportional to the location of the seaming heads (16, 18) and compares these signals with the data stored in circuitry (20). When the glass (G) has moved downstream to the position to be seamed, the seaming heads (16, 18) are then moved to the position of the detected profile of glass (G) to perform the seaming operation.

Abstract: A torque limiter having a locking stud which radially slides in a drive part enters an associated slot in the inner periphery of a driven part coaxial with the drive part under the action of a radial-thrust blade spring. When an excessive torque is present between the drive and driven parts, the stud tends to leave its housing to disengage the drive and driven parts and thereby it laterally and outwardly clears intermediate rollers in order to decrease the distance between the spring and the stud and so that the force applied by the spring shall not increase during such unlocking.Thus the unlocking is immediate and the oscillatory zone of the prior-art limiters is virtually eliminated.

Abstract: A container housing liquid medication is provided together with a syringe and a coupling member for use in orally administering the medication to a patient. The coupling member is fastened to the container and includes a head member projecting upwardly to receive an inner tip of the syringe barrel. The liquid medication is dispensed from the container into a barrel of the syringe through a bore of the head member when a plunger is moved within the syringe barrel. After a predetermined amount of medication is received by the syringe barrel, the syringe barrel is removed from the head member and the predetermined amount of medication is administered orally to the patient. A cap member attached to the coupling member by means of a strap closes off the bore so that no medication escapes from the container when the syringe is disconnected from the head member.

Abstract: A multiple spindle dividing head in which each spindle is driven in synchronism from a common drive shaft adapted to be driven from a single source of power which may be pneumatic, hydraulic or electrical, the spindles being moved automatically from an open to a closed work-piece engaging position by pneumatic or hydraulically actuated means which maintain the spindles in the closed position as they are rotated and yet permit the spindles to be readily opened in any rotative position to release the work-pieces engaged thereby.
