Abstract: This invention relates to an improved process for preparing reduced density roast coffee beans. The improved process comprises predrying green coffee beans to a moisture content of from about 0.5% to about 10% by weight, fast roasting the beans, and cooling the roasted beans. The resulting roasted beans have a Hunter L-color of from about 14 to about 25, a Hunter ΔL-value is less than about 1.2 and a whole roast tamped bulk density of from about 0.28 to about 0.38 g/cc. The resulting roast coffee beans are more uniformly roasted than traditional reduced density coffee beans.

Abstract: The invention relates to an optical amplifier, in particular for optical fiber telecommunications lines, comprising an erbium-doped laser-emission active optical fiber and a luminous pumping laser source operating at a predetermined wavelength, in which the ac­tive optical fiber comprises ytterbium as the further dopant, which exhibits an absorption of light at the emission wavelength of a pumping laser emitter. for example a commercially available three-level diode-pumped laser of the Nd:YAG type, operating be­tween 900 and 950 nm, which is different from the wavelength at which erbium alone can be pumped, and which is adapted to transfer the energy thus absorbed to the erbium contained in the fiber. thereby causing a population inversion thereof adapted to generate a stimulated light emission in the presence of an optical trans­mission signal. The use of ytterbium in the active fiber enables the achievement of a sufficiently wide spectrum of absorption, such that the use of a laser of high power and low cost for the active fiber pumping within the amplifier is made possible.

Abstract: A rongeur (10) with special features applied to the footplate area to separate the intersection of stress fields to allow the rongeur (10) to be reduced in size and mass without materially reducing the strength of the rongeur (10). A transverse groove (40) is used at the intersection of the anvil surface (28) of the base plate and the shank base plane (32). Also the base of the footplate recess is offset from the shank base plane (32) and the inside wall of the recess meets the recess base in a gentle curve. These features can be used individually or together to separate the intersection of stress fields in the footplate area and thus allow the size of the footplate to be reduced without materially reducing the strength of the rongeur (10).

Abstract: An optical equalization receiver for countering the effects of delay distortion is realized by utilizing dynamically controllable Fabry-Perot etalon structures. By dynamically adjusting the frequency response of an etalon that is in a feedback loop configuration, the associated delay characteristic of the etalon may be used to counter the effects of delay distortion, thereby allowing higher transmission rates and transmission distances to be achieved. In one exemplary embodiment, an optical receiver comprising a reflective Fabry-Perot etalon and a piezoelectric transducer is used in a feedback loop configuration wherein a feedback control circuit monitors an output signal from the etalon for generating a control signal representing the amount of delay needed to compensate for distortion in an optical signal incident on the etalon. Specifically, the control signal causes a change in the optical path length of the etalon that results in a shift in its frequency response for producing a delay substantially equal and opposite to the associated delay distortion.

Abstract: An apparatus which measures the usage of toner in a developer unit. A donor roll (74) receives toner material from a mixer (44). The mixer fluidizes the toner with the pressure from newly discharged toner moving the fluidized toner from one end of the developer unit to tile other end thereof. An electrical bias is applied between the donor roll and mixer. The current biasing the mixer is detected and a signal transmitted in response thereto corresponding to the usage of toner in the developer unit. This signal controls the discharge of toner into the developer unit.

Abstract: The low-voltage power circuit breaker which has ON, OFF and TRIP positions is able to separate the contact pieces (1, 2) very quickly after tripping in response to an excess current. The excess current trip device in this case acts directly on a transmission lever (10) which on the one hand unlatches a switching-off latch (8) and on the other hand releases the support from two pivoting discs (14) which are spring-loaded in the switching-off direction. Thereafter, two mutually separated mechanical systems are accelerated. The first system, consisting only of the transmission lever (10), of the switching-off latch (8), of a switching-off lever (5) with an energy-storing switching-off spring (6) and of the moving contact piece (2) carries out the contact separation very quickly. The second system, which is now separated from the first system and contains all the other parts of the mechanical drive, is moved by the pivoting discs (14) which are spring-loaded in the switching-off direction. When the power circuit breaker is switched on and off by hand, the two systems are coupled to one another. Switching on by hand takes place independently of the operator's speed of operation, by releasing a switching-on latch (34) of the spring-loaded moving contact piece (2). <IMAGE>

Abstract: A method which comprises using a specified dye taken up by erythrocytic nucleated cells so that their nuclei are stained and can be readily differentiated from other cells by measurement with a flow cytometer is disclosed. 
     The method for differentiating erythroblasts from other cells relies basically upon flow cytometry by two-step staining that uses a first fluid that is an acidic hypotensive fluorescent dye solution and a second fluid that is a solution that changes the osmorality and pH of the first fluid. The first fluid further contains a fluorescent dye that diffuses into erythroblasts to specifically stain their nuclei, and a group of erythroblasts is separated from other cell groups on the two-dimensional plot constructed with the flow cytometer, whereby the results of erythroblast differentiation are computed.

Abstract: A keyer with variable shaping combines the benefits of a luminance keyer with those of a linear keyer using a single set of gain and clip controls. A key signal is input to a first amplifier (10) having a high gain that is variable over an upper portion of a gain control signal's range. The output of the first amplifier is compared (20) with a clip control signal and input to a second amplifier (30) having a low gain that is variable over a lower portion of the gain control signal's range. The second amplifier includes a feedback circuit (39) that provides minimum gain and shaping when the feedback signal is maximum, and provides maximum gain and shaping when the feedback signal is minimum. 
     Therefore the overall gain of the variable gain amplifier varies so that the low gain end of the range includes gains required for linear keying with no visible shaping, and the high gain end of the range includes gains required for luminance keying together with the required shaping. Between the low and high gain ends the shaping is gradually added.

Abstract: An apparatus (48) which advances a sheet (25) hrough a transfer zone (64) and into registration with information developed on a moving member (20). The sheet (25) is advanced to a position wherein a leading portion thereof is immediately ahead of the transfer zone (64) relative to the forward direction of movement of the moving member (20) and a trailing portion thereof is within the transfer zone (64). The trailing portion of the sheet (25) is advanced through the transfer zone (64) at a first velocity and the leading edge of the sheet (25) is advanced in a region immediately ahead of the transfer zone (64) at a second velocity, which is less than the first velocity, so as to create a buckle (27) in the leading portion of the sheet (25) positioned immediately ahead of the transfer zone (64) relative to the forward direction of movement of the moving member (20). The buckle (27) functions to eliminate relative velocity between the photoconductive belt (26) and any portion of sheet (25) within the transfer zone (64) so as to substantially eliminate slip between the sheet (25) and the photoconductive belt (20).
