Abstract: In a method of separating bacteria from a bacteria containing liquid sample by means of a dish-like centrifuge container (21) having an upper opening (25) defined by a radially inwardly extending rim portion (24), the following sequential steps are carried out. The centrifuge container is rotated at a high rotational speed. A volume of a high density component of a density higher than the density of the bacteria is introduced into the centrifuge container, whereupon a volume of a low density component having a density lower than the density of the bacteria is introduced into the container so that a two component gradient separation layer (60) comprising a high density layer (61) and a low density layer (62) is formed within the centrifuge container (21). The liquid sample is introduced through a supply tube (32) into the center of the centrifuge container, and owing to the centrifugal force generated by the rotation of the centrifuge container, the liquid is thrown outwardly from the center of the centrifuge container. The bacteria are forced into the low density component layer (62) and deposited in the interface (63) between the two layers (61) and (62), while the liquid sample is discharged (66) from the upper opening of the centrifuge container through a notch (26). A flushing agent is introduced into the centrifuge container and discharged from the upper opening thereof together with any material adhering at the peripheral surface of the gradient separation layer (60). The centrifuge container (21) is decelerated to a low rotational speed, whereafter a suction pipette (40) is activated and moved from a first position having its tip remote from the inner surface of the peripheral wall of the centrifuge container (21) to a second position having its tip arranged adjacent to said inner surface, while a volume of a transfer liquid is introduced into the centrifuge container so that liquid substance included in the centrifuge container is sucked off therefrom through the pipette tube (41) of the suction pipette (40).

Abstract: The Charge Coupled Device ("CCD"), which is an integrated circuit array sensor in "chip" form, of a pushbroom spectrographic imager is operated to achieve fast dumping of unwanted rows of charges. The chip is provided with antiblooming structure in the image area and the first row of the storage area. The rows of charges are divided into groups of several rows. The groups of interest (i.e. the active groups) and those that are not wanted (i.e. the discard groups) are so designated. The rows in each group are summed in the antiblooming structure of the storage area. The active summed rows are sequentially transferred by the chip's transport register to an output amplifier, wherein the individual charges are read out and digitized to yield signal values for collection.

Abstract: According to the invention, there is provided a door hinge comprising a spring that plays the role of both a torsion spring and a compression spring, wherein its resilient force is used for axially pressing a movable cam against a matching fixed cam it comprises and thereby facilitating the opening and closing motion of the door with which it is used by giving said cams such specific configurations that the spring accelerates the opening motion of the door from a given angular position of the door and locks the door at a particular open position and at a closed position.  Since a door using such a hinge that comprises a spring whose resilient force constantly biases the door to open can be either opened to any de-sired angle or closed and sustained there under a locked condition when the rotary shaft of the hinge is firmly connected to the door, it can be used for a flap door or another vertically rotatable door such as a toilet lid to sustain the door to an open position under a locked condi-tion even if the resilient force of the spring is nulli-fied at that position and the door is liable to be pushed back by an obstacle such as a wire located behind the toilet assembly comprising the lid.  Therefore, the door is protected against any turning effort and other forces which are unintentionally applied to the door.

Title: Phase locked loop including non-integer multiple frequency reference signal
Inventor: MOLLOY NICHOLAS J
IPC: H03L7/06
Filed: 1991-02-12
Granted: 1997-01-07
Abstract: A digital phase locked loop is employed to realize an output clock signal from a reference signal having a frequency which is not an integer multiple of the output clock signal frequency. This is realized by employing a programmable divider for dividing the reference signal which is dynamically controlled by a controllably variable base divisor. The base divisor control is responsive to the reference signal and to a phase error signal. The base divisor is generated to obtain a desired fractional division of the reference signal frequency and in a manner tominimize the amplitude of any resulting "high" frequency jitter in the output clock signal from the loop.
