Abstract: ABSTRACT             The invention relates to the containment of a block of rodenticide bait in a manner that precludes the contact of said bait by unintended target species such as children, pets and wildlife.  This device is used to provide a compact method of presenting baits to target species such as house mice, in a manner that is both safe and effective, and in such a manner that will not allow probing at the toxic substance with flexible objects such as wires, straws and other similar structures that might be bent into an easily fabricating configuration by children.  The use of a sophisticated series of internal baffle structures that protect the bait from contact by objects inserted from the outside while allowing a rodent to easily traverse the bait station and consume the bait contained therein, make this device one of the most practical methods of presenting poisoned substances in areas that might become accessible to children, pets and wildlife.

Granted: 1994-07-26
Abstract: ABSTRACT     A sensor for an inclination measuring device is disclosed which comprises a capsule   part-filled with a conductive liquid.  First to fourth electrodes A-D are disposed within the capsule in contact with the liquid.          An electrical signal is applied between electrodes C, D and one then the other of electrodes A, B, to derive a signal indicative of the degree of immersion of the electrode A, and then the electrode B within the liquid.  The ratio of these signals is related to the angle of inclination of the capsule about the reference axis O and relative to a first reference angle defined at the gap between the electrodes A. B.   The capsule 1 is also constructed to compensate for thermal effects, by forming the sides of the capsule so that they are responsive to pressure change within the capsule caused by thermal expansion of the contents of the capsule to expand the volume of the capsule, to keep the level of liquid therein constant.

Abstract: Disclosed is a control circuit for use in missiles having a nose portion rotatably mounted in bearings on the forward end of a cylindrical main body portion of the missile for rotation about the longitudinal axis of the missile and is provided with aileron and elevator control surfaces.  By remote control the nose portion can be brought to a preselected roll attitude.  The control circuit ensures that the nose portion takes the shorter path to arrive at a required roll attitude.          The control circuit comprises a difference unit to which first and second input signals are in operation applied to produce a signal representative of the difference between the two input signals.  A logic circuit receives a signal from the difference unit to produce in response to signals applied thereto exceeding a predetermined value in respect to a datum an output of a constant value equal to twice the predetermined value and on the other side of the datum.  An adding unit receives the signal from the logic circuit and the signal from the difference unit to produce an output signal representative of the algebraic sum of the two signals applied to the adding unit.  A switching arrangement switches to a first condition in response to signals from the adding unit having values to one side of the datum and to a second condition in response to signals from the adding unit having values to the other side of the datum.

Abstract: A frame start word derived by superframe formation is found by testing for the presence of a correct binary value combination each bit position in a time window having the length of as many bits as framing bits are spaced apart, with the inclusion of so many overframes that a decision can be reached on the possibility of a relationsip to the frame start word. If this is to be excluded the corresponding bit position is flagged and thereafter no longer taken into consideration. Otherwise, the next binary value of the corresponding bit position is inferred from the binary value present. The procedure is continued, always including the same number of overframes until only one unflagged bit position remains.
