Inventor: SIGNORELLO JAMES W
IPC: E04G17/14
Filed: 1991-03-20
Abstract: ANCHORING APPARATUS FOR A BRACE MEMBER FOR SUPPORTING A WALL AND METHOD FOR USE OF THE SAME                     ABSTRACT           This invention includes an anchoring apparatus for anchoring one or more elongated diagonal  brace members used to temporarily support a vertical  wall relative to the ground during construction and a method for  using  the  anchoring  apparatus.    The  anchoring apparatus  comprises  a  base  member   including substantially flat base plate having upper and lower surfaces, with the lower surface cooperating with the ground at a location spaced from the wall, and further including a means for securing the flat plate to the ground to prevent sliding.   The anchoring apparatus further includes a swivel pocket pivotally attached to the  base  member  and  sized  to  slidably  receive construction lumber readily available on a building site.

Filed: 1991-04-09
Abstract: METHOD AND APPARATUS FOR SECURING A MANBASKET                 TO A FORKLIFT Abstract of the Disclosure A method and apparatus are disclosed for securing a manbasket to the tines of a lifting fork of a forklift. A preferred embodiment comprises a tine clamp mounted to a tine socket on the manbasket.  The clamp automatically applies a self-adjusting gripping force to the underside of the tine whenever the fork has elevated the manbasket and automatically releases the tine when the manbasket is resting upright on a reference surface.  The tine clamp comprises a lever pivotably mounted at mid-length to the tine socket, at least one gripping cam rotatably mounted to one end of the lever, and a cam release member pivotably mounted to the opposite end of the lever.  The lever is biased to keep the gripping edge surface of the cam in contact with the underside of the tine whenever the tine is in the socket and the manbasket is elevated.  The cam has an outwardly spiraled profile to enable it to apply a gripping force to the tine that increases as the tine is urged more strongly out of the socket.  The cam-release member contacts the reference surface when the manbasket is resting upright thereon, which causes the lever to pivot against the bias and draw the cam away from contact with the underside of tine, allowing the tine to be withdrawn from the socket.

Title: Animal watering device
Inventor: LISCHKA KENNETH A
IPC: A01K7/04
Filed: 1991-06-18
Abstract: "ANIMAL WATERING DEVICE"          ABSTRACT OF THE DISCLOSURE         A   watering   device   for   animals   includes   a cylindrical container with an open top and a surrounding lip around  the  open  top.   A closure member for the open top includes  a  disc  which  is  flat  with  a  surrounding skirt extending along the sides of the container.   The skirt has holes to allow the escape of air trapped under the closure member.   The closure member carries a downwardly extending guide member on the under surface which carries a float and which is guided for movement in a vertical direction.   The float is located under the water surface so that depression of  the  closure  member and the  float do not significantly alter the water depth.  The float keeps the closure member up against the lip thus fully closing the container.  The animal depresses the closure to a level under the water surface to access the water for drinking.  If the water level falls, the downward pressure for the animal to access the water engages a valve to refill the container.  The natural tendency of the animal  is  to maintain the water level at a required level below the top.   This arrangement reduces the tendency of the animal to spoil or spill the water.

Title: Mirrorback coating
IPC: G02B1/10
Filed: 1991-01-04
Abstract: 2050923 9110563 PCTABS00006 A lead-free composition capable of being applied as a film and hardening to form a protective layer on the back of a mirror comprises a fluid organic resin and a corrosion inhibitor selected from the group consisting of dicyandiamide, metal or acid salts of dicyandiamide, hydrogen cyanamide, and 2-cyanoacetamide. The organic resin may be any thermoplastic or thermosetting resin suitable for coating the reflective and other metallic layers of the mirror. Exemplary resins include alkyd resins, acrylic resins, modified alkyd resins, polyesters, urethane oils, vinyl halide polymers or copolymers, oleoresinous varnishes, nitrocellulose compositions, phenol-formaldehyde resin varnishes, and epoxy resins.  Preferably, the resin is an alkyd or modified alkyd resin. The aforementioned corrosion inhibitor may be present in an amount from about 0.1 to 20 weight percent, preferably 0.5 to 10 weight percent, of the organic resin coating system. The resin system should be essentially free of lead and lead salts. To inhibit the corrosion of metallic film layers on mirrors, a mirror having a glass substrate layer and a metallic film layer thereover should be obtained, after which the fluid organic resin coating system containing the aforementioned corrosion inhibitor is applied over the metallic film layer. The organic resin coating system is then hardened to produce the protective coating layer over the metallic layer.  Other articles having metallic surfaces may also be protected by the resin system containing the novel corrosion inhibitor of the present invention.

Title: Electronic duplication prevention of keyless entry signal featuring energy conserving method of transmission
Inventor: KRAMER DENNIS A
IPC: B60R25/24
Filed: 1991-09-20
Abstract: ABSTRACT   A remote keyless entry device providing vehicle access which utilizes a friend/foe screening technique comprising an initial sequence of two pulses which precede a transmitted code. The first pulse is transmitted on a 50 kHz carrier frequency while the second is transmitted on a 38 kHz carrier frequency. Once the vehicle receives the pulses, a match is acknowledged permitting the subsequently following transmitted vehicle code to be received and compared to the code stored in the receiver memory. The specific vehicle code in the preferred embodiment consists of five integers. These integers are transmitted by the transmitter in serial fashion. Each integer is represented as a time interval between a start and a stop pulse. Each time interval is equal to a fixed increment of time multiplied by the respective integer value. The stop pulse of the first integer is the start pulse of the second and the stop pulse of the second is the start pulse of the third, etc. Once the vehicle receiver receives the sequence of integers, the receiver microprocessor compares the integers received with integers stored therein.          If a suitable match is accomplished a logic signal is generated and communicated to the central locking unit. A central locking unit which controls individual door access mechanisms then positions the respective mechanisms according to the instruction received therefrom.                             - i -

Abstract: A neural network for adjusting a setpoint in process control replaces a human operator. The neural network operates in three modes: training, operation, and retraining. In operation, the neu-ral network is trained using training input data along with input data. The input data is from the sensor(s) monitoring the process.      The input data is used by the neural network to develop output data. The training input data are the setpoint adjustments made by a human operator. The output data is compared with the train-ing input data to produce error data, which is used to adjust the. weights of the neural network so as to train it. After training has been completed, the neural network enters the operation mode. In this mode, the present invention uses the input data to predict out-put data used to adjust the setpoint supplied to the regulatory con-troller. Thus, the operator is effectively replaced. The present in-vention in the retraining mode utilizes new training input data to retrain the neural network by adjusting the weight(s).
