Title: Apparatus and method for draining a swimming pool cover
Inventor: HODAK FRANK J
IPC: E04H4/10
Filed: 1989-02-02
Granted: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE       A method and apparatus for draining a swimming pool cover includes upper and lower flanged members having a central drain passage for sealably fitting around a hole formed in the pool cover. A drain tube upwardly extends from the upper flange and communicates with the passage thereof. An elbow fitting or the like communicates at one end with the passage in the lower flange and at another end with a flexible conduit. The conduit extends from the elbow fitting for connection to a conventional return water port fitting located at the pool sidewall. As water accumulates on the cover to a predetermined depth, the excess water drains into the drain tube and travels through the flexible conduit to exit the pool at the sidewall port fitting. A perforated drain closure member is also preferably employed around the drain tube to prevent debris blockage and to provide for adjustably regulating the height and weight of water stored on the cover for hold-down purposes.

Title: Tracking device for optical memory card
Inventor: HORIE KIYOSHI
IPC: G11B7/09
Filed: 1989-04-07
Granted: 1993-07-20
Abstract: ABSTRACT     A tracking device for an optical memory card according to the present invention includes an inclination information sampling unit for calculating changes per unit time of the low-frequency component of a tracking error signal, a detection unit for outputting a detection signal for the duration of deviation occurring during tracking that exceeds a predetermined standard range, a cumulative addition unit for cumulatively adding the output of the inclination information sampling unit to the low-frequency component of the tracking error signal that is generated when the detection signal is generated at each unit time during the generation of detection signal, and a switch-over unit for outputting as an optical system tracking control signal the tracking error signal during the normal operation and the output of the cumulative addition unit during the outputting of the detection signal.          Accordingly, skew information on an optical memory card is obtained in advance during the writing/reading of the card, and a signal approximating to a normal tracking error signal is schematically generated utilizing the skew information thus obtained for a short period of time during which a normal tracking error signal is lost or is about to be lost due to dust or a scratch existing on the card.  In consequence, normal tracking state can be maintained without interrupting the writing or reading of the optical memory card, and the schematic tracking state can be returned to the original normal state after this period has passed.

Abstract: ABSTRACT OF THE DISCLOSURE A driving rotary shaft is rotatably carried on a compressor body of a variable displacement compressor. On axial   one side of a sleeve slidably carried  on  the driving rotary shaft, there is disposed a first spring of a displacement setting device for biasing the sleeve in one    axial direction  and     holding       a stopper, with which the sleeve is engageable, at a stop position on the driving rotary shaft. On the axial   other side of the sleeve, there is disposed a second spring of the displacement setting device for biasing the sleeve in the other axial direction, the second spring being weaker than the first spring. At the starting of the compressor, the first spring holds the stopper at the stop position against a repulsive force of the second spring to hold the sleeve engaged with the stopper at a fixed position. This makes it possible to set the strengths  of individual members and the capacity of a clutch to be smaller than those in the prior art, leading to reductions in size, weight and cost of the entire compressor.

Title: Connecting device for optical fibers
Inventor: MEIS MICHAEL A
IPC: G02B6/42
Filed: 1989-05-26
Granted: 1993-08-31
Abstract: Abstract of the Disclosure A known optical fiber connector include  an elongated mount which is encompassed by a housing that releasably pinches a free end of an optical fiber against a groove in the surface of the mount, thus connecting that free end either coaxially to a free end of another optical fiber or to an opto-electronic element.  That connection is made more secure by a block on which the mount can be precisely lodged.  The block is formed with a channel extending substantially parallel to the mount and a slide that is slidable in the channel between advanced and retracted positions.  When advanced, a protrusion on the slide causes the housing to be deformed, thus enabling a free end of an optical fiber to be positioned in the groove of the mount.  When the slide is retracted, the housing returns to its undeformed state and pinches the optical fiber against the groove.  Upon movement of the slide to its retracted position, the protrusion causes a post to grip an intermediate portion of the optical fiber, thus securing the fiber against accidental movement.  By forming the block with a series of channels and slides, a number of pairs of optical fibers can be interconnected coaxially.

Abstract: The load-weighing apparatus faultlessly detects even smallest load variations in the lower load range. For this purpose wire strain gauges are mounted at structural parts or components of the elevator car and these structural parts or components are subjected to bending under the load to be weighed. The wire strain gauges are interconnected to form a bridge circuit. An amplifier circuit is connected at the output side of the bridge circuit and has a higher gain in the lower load range. When an input voltage corresponding to a predetermined load occurs at the amplifier circuit, the gain of the amplifier circuit is switched to a lower value. It is thus possible to detect loads throughout a greater range of loads.

Abstract: A method and apparatus for electrostatically flocking a thread-like or yarn-like material. This material rectilinearly and continuously or intermittently is moved through an electrical field which is generated between electrodes having non-planar yet symmetrical potential surfaces. This electrical field preferably is generated between curved potential surfaces of the electrodes. The flock is shot into the adhesive coating of a given thread not only radially but also at an angle. The thread does not have to be turned. As a result, a dense and improved flocking is achieved all around the yarn or thread in a simple and economical manner.

Abstract: Running sole structuring for a ski, especially for a cross-country ski. The object of the invention is to provide a new profiling which combines optimum gliding and climbing characteristics. Therefore, it is the object of the invention, to provide a suitable shaping of the profiling which fully considers the special requirements under different snow conditions as well as the special loadings of the ski during the push-off and gliding phases, as well as the process of sticking and gliding friction and the transitional phases associated therewith directly. This object is solved according to the invention by the provision of exclusively straight, vertical and parallel arranged profile edges with respect to the direction of the run which are also two-dimensional in the plane of contact with the snow and are statistically arranged and, wherein the adjacent pairs of climbing edge rows lying behind each other lie on a gliding arc. It is preferred when the mean edge length ( &upbar& bn) in the push-off region (A) is the smallest and increases continuously and/or discontinuously toward one ski tip, respectively ski end, and wherein in the end region of the longitudinal extent of the profiling the maximum value for the mean edge length ( &upbar& bn) is attained.
