Abstract: ABSTRACT OF THE DISCLOSURE    An optical recording card is produced using a transfer type optical recording medium. The transfer type optical recording medium comprises a base film, a peeling layer, an optical recording layer and a light pearmeable adhesive layer which are successively superimposed one above another to constitute a layered structure.  A protective layer is adhered to the transfer type optical recording medium with the aid of an adhesive layer and the base film is then peeled off together with the peeling layer.  Next, the protective layer to which the optical recording layer is adhered is adhesively attached to a card base in such a manner that the optical recording layer is interposed therebetween whereby an optical recording card is completely produced.  The transfer type recording medium can be preserved in such a state that it is wound about a reel.  Accordingly, the transfer type recording medium is adhered to the protective layer when the optical recording card is produced, and thereafter it is adhered to the card base.          Thus, the optical recording card can be produced at a high productive efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE            A fish line release consisting of a pair of elon-gated jaw members interconnected at one end and having free ends movable between open and closed positions biased toward the closed position by a spring.  Resilient fish line enga-ging pads affixed to the free ends releasably retain a fishing line and alignment projections formed on the jaw members as-sure alignment of the fishing line with the pads when "loading" the release and also restrain the jaw member free ends from relative lateral displacement.  The pads are attached to the jaw members by adhesive which is received within recesses which aid in interlocking and bonding the adhesive to the jaw members, and the jaw members include stops which prevent overstressing the spring when squeezing the jaw members to the open position.

Title: Power converter with reduced switching loss

Granted: 1991-09-03
Abstract: POWER CONVERTER WITH REDUCED SWITCHING LOSS                 Abstract of the Disclosure A DC to DC power converter having reduced switching loss for operation at high frequencies.  As disclosed, a buck, or forward, converter includes a first FET as the switching device in series with an inductor and a second FET as the flywheel device.  At the common node to which the two FET's and the inductor are connected, there is sufficient capacitance that the FET's may be turned off without appreciable voltage change across the FET's. The value of the inductor is chosen, with respect to the input and output voltages and frequencies of operation involved, to insure that the inductor current polarity reverses each cycle, raising the node voltage to the level of the input voltage, substantially eliminating turn-on losses of the first FET. Control circuitry is provided for regulation of the power converter to control the peak-to-peak current in the inductor and to insure that at least a selected minimum value of the inductor current is present for each cycle of operation of the converter.  An over-voltage protection circuit for the output of the converter is also provided.

Title: Control and means for vibration attenuating damper
Inventor: MILLER LANE R
IPC: F16F9/20
Filed: 1987-09-28
Granted: 1991-04-09
Abstract: Abstract Of The Disclosure A damper of the semi-active type is controlled such that the damping forces generated by the damper, in response to relative movement between spaced members inter-connected by it, are caused to be of minimal (ideally zero) magnitude when the product of the relative displacement between the members and the relative velocity between the members is greater than zero.  The foregoing control policy may be implemented by purely mechanical elements, or by electronic elements of relatively simple and inexpensive types.

Abstract: CHEMICAL TREATMENT FOR ALGAE CONTROL IN OPEN WATER SYSTEMS       Abstract of the Invention Algae growth in an open water system such as a water cooling tower is controlled by reducing the amount of light available for the algae to photosyn-thesize.  The light available for photosynthesis is reduced by incorporating a dye into the water in the water cooling system.  Thus the dye absorbs the light necessary for photosynthesis and in turn prevents algae growth.  Preferably fluorescein at a concen-tration of 0.2 to 800 parts per million is incorpo-rated into the water in the water cooling system.  Other dyes can be selected depending on the particular algae.

Abstract: ABSTRACT         COPPER CHROMITE HYDROGENATION CATALYST           A copper chromite hydrogenation catalyst of enhanced activity is obtained by an ante-pre-reduction treatment in which a copper chromite catalyst precursor is soaked in a reducing atmosphere at temperatures below a pre-reduction temperature (typically about 140 °C) at which appreciable pre-reduction of the catalyst can be detected.  This catalyst is characterised by particles of reduced copper substantially all of which have an average particle size of less than about 300 x 10-10 m (300.ANG.), which have an average particle size of less than about 100 x 10-10 m (100.ANG.), and which are substantially uniform-ly distributed on a chromium-containing support.  Typi-cally such catalysts exhibit a copper surface area of about 18.5 m2/g as determined by N2O decomposition at 20°C, compared to a corresponding copper surface area of 4.5 m2/g for a catalyst which has been produced by conven-tional pre-reduction of the same catalyst precursor.

Abstract: Abstract of the disclosure A method of taking pictures of a quick-moving object by means of a video apparatus, whereby the quick-moving object, e.g. a paper web, is exposed to a short light impulse and a light impulse reflected from the object is used to produce an image on an image sensor of semiconductor type in the camera. The light impulse brings dot detectors of the image sensor into a detec-tion state corresponding to the light intensity of each dot, where they remain after the end of the light impulse, whereby the image remains in the storage of the image sensor and can in a normal way be read and recorded on a video tape in the video tape recorder.

Title: Plastic module rigidizing system
Inventor: DAHOWSKI DONALD E
IPC: E04H4/14
Filed: 1988-11-02
Granted: 1991-06-25
Abstract: ABSTRACT A system to impart controlled rigidity to the flexure of a molded plastic structural module is provided. In the system a means for effectively bonding two plastic members and which maintains the integrity of the bond under severely ambient conditions resulting from differences in coefficients of expansion, moisture, flexing and the like, is disclosed.  Delamination of the bond, particularly under the flexing condition is minimized by an intermittent bonding surface such as by bonding at the peaks or top points solely  of a serrated surface.  The system is particularly useful in the provision of a rigidizing member for treads of a plastic stair module for swimming pools.   In use as a support for prefabricated plastic swimming pool stair modules, the preformed stair module is equipped with a suitable structural shaped metal rigidizing element that has been encapsulated in a plastic composition. The rigidizing element is then bond to the underside of the tread areas of a plastic stair module which has a discontinuous or serrated surface. This preformed stair module is then fitted at the construction site with support posts that are secured to the rigidizing structural element under the stair tread areas and the stair module is lowered in place and leveled.  The bottom of the post is then secured in concrete to provide a footing.
