Abstract: Abstract The invention relates to a laying nest for at least one chicken or other type of egg-laying poultry, the laying nest being provided with a floor which has a slight slope towards a collecting device for the eggs laid by the poultry, over which floor a sweeper member can swing for removal of poultry from the floor, which sweeper member is attached for pivoting to a shaft extending above the floor in a horizontal plane.      The invention has for its object to give a laying nest a form such that turning out can be performed automatically and virtually without checks being necessary,  for instance with automatically controlled hydraulic, pneumatic or electr-ical means.      In order to realize this object the invention proposes a laying nest of the type described which has the feature that the sweeper member is coupled via spring means to operating means which possess two stable,  extreme positions, in which first position the sweeper member is forced by  the spring means to an inactive rest position,   and in which second posi-tion the sweeper member is forced by the spring means to a second inactive rest position via a swinging movement such that any poultry that may be present on the floor is subje-cted to a turning out  force from the sweeper member as  a result of the tensioning  in the spring means caused by  the operating means.

Title: Cover for water container of oral rinsing device
Inventor: HORNTRICH GUENTER
IPC: B65D49/02
Filed: 1987-12-31
Granted: 1992-03-03
Abstract: COVER FOR WATER CONTAINER OF ORAL RINSING DEVICE     Abstract of the Disclosure A stationary hinged covering device for a removably arranged container of an oral rinsing device comprises an upright support with a horizontally disposed stationary carrier secured to the support.  A container cover has a front portion and a slightly heavier rear portion with a hinge pivotally connecting the container cover to the stationary carrier at a point between the front and rear portions of the cover.  The cover has a rear-wardly and downwardly extending flap at the rear portion thereof arranged to engage the rim of a container when postioned under the cover.  When the container is removed the front portion of the cover swings in an upward direction about the hinge while the rear portion  swings in a downward direction.  When the container is positioned directly under the cover the cover is horizontally disposed.                    Background of the Invention The present invention relates to a novel covering device for the water container of an oral rinsing device having improved use properties.         The reservoir for the liquid of an oral rinsing device is generally arranged in either a fixed or movable condition.          The fixed arrangement has a serious disadvantage in that the entire oral rinsing device must be taken to a water source for the purpose of refiling the container.  As a result, movably arranged liquid containers are generally preferred.  These liquid containers are in most cases equipped with a removable cover to prevent contamination of the water provided for oral rinsing.

Title: Non-contact determination of the position of a rectilinear feature of an article
Inventor: MORRISON BRUCE R
IPC: G01B11/00
Filed: 1988-04-19
Granted: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE      A high resolution CCD video camera (6) is positioned and aligned with respect to an illuminated article (7) so that a straight edge of the article, or a straight line junction between a bright zone and a dark zone of its surface, crosses the field of view of the camera in a direction substantially parallel  to the rows of the camera's orthogonal array of rows and columns of light responsive elements,to divide that field of view into bright and dark zones.   A frame store and digitiser (9) converts the individual signals generated by the elements into digital grey values.  The grey values derived from the elements of each row are summed by a computer (10) to produce a linear array of summation values positionally related to the respective columns, and the computer then determines the position of the edge or junction to a sub-column spacing accuracy by determining the mean value of two of the summation values selected respectively from a row receiving energy from the bright zone and one receiving energy from the dark zone and establishing a position in the array for the mean value, and thus for the feature, by interpolating the mean value between the two summation values immediately above and below it in magnitude.

Abstract: ABSTRACT OF THE DISCLOSURE     The touch panel system of the present invention comprises two light emitters  at the upper opposite corners of the cathode screen.  The light emitters each emit a light beam which is deflected in an annularly sweeping pattern across the face of the screen.          When the beams are interrupted, the time in the sweep of the beam is sensed and this timing is used to calculate the location of the obstruction which interrupted the beam.
