Abstract: The present invention provides a photodetection apparatus having such an arrangement that when signals from the light receiving means in the photodetection device are sampled at a frequency substantially equal to the lowest frequency at which the source of pulse rays is lighted on, one of the noise signal I nc  due to the pulsed illumination as from the fluorescent lamp and the normal output signal I nc  from the laser beam necessarily presents for each of the sampling periods. In the preferred forms, output signal values sampled in the number of cycles corresponding to at least three times the sampling period are compared with each other. If it is judged that one output signal is larger than the other two output signals which are substantially equal to each other, it is determined that the one output signal is a normal output signal I sc  from the laser beam. The one output signal is then taken for the subsequent signal processing step. In the other case, all the output signals are determined to be noise signals from disturbance rays as from the fluorescent lamp, including AC components and will not be taken for the subsequent signal processing step. In such a manner, any adverse affection due to the pulsed AC rays can be eliminated.

Abstract: Objects of thermoplastic polymer foam such as, e.g., sheeting of polyolefins such as polyethylene, are treated at elevated temperatures effective to rapidly purge the foam of a substantial portion of the residual blowing agent. Significant economies are achieved by reducing the amounts of residual blowing agents (such as flammable, toxic or environmentally hazardous gases) to levels presenting no fire hazard or other safety hazards in times substantially less than required in conventional aging under ambient conditions. The processes can be carried out in ovens or other heating zones which form continuations of the basic production line, with the extracted blowing agents recycled or disposed of by combustion.

Abstract: A multi-function apparatus has its subassemblies configured to perform a number of functions by an internal processor, stored programs, and user selected inputs. A display (12) is included for showing screen configurations, each of which indicates a sub-instrument or application of the apparatus. Each screen configuration includes a plurality of control point fields which are selected from a limited set of types of control point fields common to all screen configurations. Each type of control point field, when selected by the user, enables the performance of a predetermined operation incident to the function. A user operable rotary input device (14) enables selection of any displayed control point field. All functions performable by the multi-function apparatus are operated through user interaction with and selection of one or more control point fields, the commonality of the control point fields providing increased ease of user operation of the apparatus. A preferred embodiment of the invention includes a multi-instrument test system particularly adapted to the testing and measuring of signals from and to radio frequency apparatus.

Abstract: The crimping tool for pressing wire end ferrules (13) has two jaws (1, 2), which are supported in a swivel bearing and can be swivelled about the swivel bearing, in particular via a drive (9) having two hand levers (11, 13). A spring jaw (8) is provided on each jaw (1, 2). The drive (9) engages at one end of the jaws (1, 2). Connected to the other ends of the jaws (1, 2) in each case is a pressure jaw (20, 21) which has a single pressing position (17) intended to cover a cross-sectional area in a universal manner. At least one of the jaws (1, 2) has two areas (7, 8) which act on the pressure jaws (20, 21) and of which one area (7) is constructed to be largely rigid, and the other area (8) is configured in a resiliently yielding fashion as a spring jaw. At least one of the pressure jaws (20, 21) is guided on one of the areas (7, 8) of the jaw in the direction of motion of the pressure jaws. A first stop (26) and mating stop (27) is provided between the pressure jaw (20, 21) and the resilient area (8) on the jaw (1, 2), and a second stop (28) and mating stop (29) are provided between the pressure jaw and the rigid area (8) of the jaw (1, 2). The distance between the two stops (26, 28) is dimensioned with respect to the distance between the two mating stops (27, 29) in such a way that, when crimping, in the essential cross-sectional area the first stop (26) and mating stop (27) are firstly in active abutment, and the second stop (28) and mating stop (29) do not come into active abutment until the area of the maximum cross-section.

Abstract: A cogeneration system is disclosed using a Stirling cycle engine (10) in which the waste heat from the engine and a generator (32) driven by the engine is used for space heating or producing hot water and the generator (32) used to produce electricity. A Stirling engine has numerous advantages over a reciprocating internal combustion engine in cogeneration systems in that the Stirling engine has a longer life, less maintenance cost, less noise and vibration and fewer emissions. With cogeneration, the added energy and and fuel required over and above that required to produce a comparable amount of heat allowed to produce the same amount of heat with a conventional furnace or boiler is often less than the amount of electric energy produced from the system thereby resulting in a efficiency greater than 100% in the production of electricity.

Abstract: Methods for scheduling sheets in an imaging system having an endless duplex paper path loop are disclosed. Preferably, the duplex loop includes a single sheet inverter without a buffer tray so as to eliminate the problems associated therewith. The basic method involves consecutively inserting copy sheets to be imaged into the duplex loop without placing any skipped pitches therebetween regardless of set or job boundaries. Duplex side ones from subsequent sets or jobs are used to fill any gaps which exist in the duplex side one sheet stream of earlier sets or jobs. Additional refinements include using simplex sheets to fill potential skipped pitches in a duplex side one sheet stream by converting simplex sheets located immediately subsequent to the duplex sheets into duplex sheets having a blank back side and scheduling the side one imaging of the now-converted duplex sheets into the potential skipped pitches. Potential skipped pitches can also be filled by shifting an appropriate number of simplex sheets at a simplex-to-duplex transition into any potential skipped pitches in an immediately subsequent duplex side one sheet stream. Further refinements include using duplex or simplex sheets to fill gaps which exist in a duplex side two sheet stream due to skip requests which occurred during the side one scheduling, inserting or imaging.
