Abstract: The apparatus employs a steel ball which is mounted in upstanding manner on a pin and a frame on which a golf club is pivotally mounted to freely pivot. The golf club is pivoted from a fixed position to impact the head of a golf club against the steel ball and an oscilloscope is used to record the acceleration and movement of the steel ball from its fixed point in response to the impact of the head and also calculates a velocity history of the steel ball. The time at which the calculated velocity is at a maximum is determined. Several impacts are made to obtain an average characteristics time (tz) and the representative spring constant (Kc) of the clubhead is calculated using the equation: Kc=0.2971×tz−2.15570.

Abstract: In a lap winding apparatus for producing a batt lap, the batt is wound onto a tube which is rotatable about a fixed axis and is driven by a revolving endless belt. The belt is arranged in a loop, formed between two deflecting rolls and is tensioned by a tensioning device. The tube which is rotatable about a fixed axis, as well as the two deflecting rolls are dimensioned, and positioned relative to each other, in such a manner that the loop at the beginning of the lap winding process embraces the tube over an initial minimum wrapping angle equal to, or larger than, 120° and preferentially equal to, or larger than, 180°. For generating a tensioning force depending on the lap diameter, the tensioning device is associated with a control device.

Abstract: A wafer edge grinding or polishing machine is provided with a pair of chucks for engaging a wafer therebetween, a fixed reference surface and a sensor which is movable with a movable chuck. Measurements are made by the sensor relative to the fixed reference plane when the movable chuck is in engagement with the opposite chuck without a wafer therebetween in order to obtain a standard measurement value. With a wafer between the chucks, the sensor obtains an actual measurement value relative to the fixed reference surface. A calculator determines the difference between the standard and actual measurements values and displays the difference as the thickness of the wafer. Multiple sensors may be used to obtain multiples readings which are averaged by the calculator to obtain a thickness measurement.

Abstract: The implantable device for long term monitoring of congestive heart failure employs a signal generator, such as within a pacemaker, to generate an electrical signal which is monitored to obtain a single or dual frequency measurement that can independently measure systemic venous and pulmonary (lung) impedance. The device is able to detect changes in resistance to a flow of current in the systemic venous system and changes in impedance to a flow of current through a lung to thereby indicate separate detection of systemic venous and pulmonary congestion.

Abstract: An actuator for opening and closing a globe valve. The globe valve has a stem through which positioning of the globe valve is achieved. The globe valve is normally biased to open position. The actuator comprises an electric motor which drives a worm and pinion arrangement. The pinion drives an output gear which gear is movable between a base and a raised position within a frame and held in the base position by a compression spring with a similar compression rating to that of the required valve shutoff. The output gear drives a worm stem bearing against the stem of the globe valve to move it against its bias in one direction to close the globe valve. The output gear and worm stem are arranged so that, when the globe valve is fully closed, the worm stem is at its extreme position in that one direction and the output gear then begins to move within its frame from its base to its raised position.

Abstract: The force plate data acquisition system measures, processes and analyzes the vertical reaction forces and various weight shifts between the ground and a golfer's feet during a swing. Plates are supported on cantilever beams through ball bearings. The beams are attached to a rigid frame and instrumented with strain gauges configured in a Wheatstone half bridge arrangement. An eight-channel strain gauge data acquisition board in a central processing unit records strain information. Data collection can be independent or controlled by a motion analysis system to provide synchronous foot force and video information. A set of BASIC programs collect strain readings from the foot plates, process the data, relate beam deflections to applied load and plots reaction force and weight shift information to the computer screen. Graphs produced are total vertical reaction force, foot-to-foot weight shift, heel-to-toe weight shift, outside-to-instep weight shift and the speeds of each.

Abstract: The pool cover is made of multi-layer light weight construction having a translucent top layer to permit sunlight to pass through an opaque bottom layer for absorbing sunlight passing through the transparent layer. In addition, a plurality of pockets are formed in the opaque layer having air encapsulated therein. When in use, the opaque layer becomes heated by sunlight thereby transferring heat by contact to the body of the water in the pool while also blocking light from the body of water to inhibit algae growth. The heated trapped air also serves to conduct heat to the body of water while also acting as a thermal insulation barrier during non-daylight hours. The pool cover may also be turned upside down in use. In other embodiment, all layers may be opaque.

Abstract: An electromagnetic actuator for driving a movable plate equipped with an optical element such as a mirror on the basis of the operation principle of a galvanometer. The structure of the movable plate is simplified, and a driving coil and a wiring are formed by aluminium vapor deposition to improve durability. When an impact brings the movable plate outside the allowable rocking range of the movable plate, a stopper prevents excessive displacement of the movable plate to thereby prevent destruction of a torsion bar that supports the movable plate. Moreover, electrical connection in the torsion bar is eliminated to prolong the service life, and a production process is simplified to reduce a production cost.
