Abstract: This invention relates to photoinitiator systems for use in addition, i.e., free radically-initiated, polymerization. 
     Photopolymerizable compositions usually contain a photoinitiator system, a polymerizable monomer, and optimally adjuvants. Often pigments are added to color or opacify the composition. The addition of pigments usually inhibits the initiation of polymerization because of competitive light absorption or light scattering, which decreases the amount of light available for absorption by the photoinitiator system. It would be desirable to be able to use pigments in combination with or as part of a photoinitiator system in a photopolymerizable composition. 
     This invention provides photopolymerizable compositions comprising:
     (1)at least one vinyl monomer capable of undergoing free radical polymerization,   (2)a visible light or ultraviolet light responsive photoinitiator system comprising:   a) a diarylidonium salt,   b) a pigment, insoluble in the photopolymerizable composition, said pigment also serving as a sensitizer,   c) one or more electron donating compounds,and, optionally,   (3) adjuvants.   
     The three component photoinitiator system of this invention can increase, by several orders of magnitude, the rate of ultraviolet light or visible light photocuring of vinyl monomers.

Abstract: The refuse vehicle comprises a refuse-collecting container which is situated on a chassis behind the driver's cab and is provided with a refuse-filling system incorporating a refuse-compressing device, in order to press the refuse in a direction of action through a container opening into the refuse-collecting container. The direction of action of the refuse-compressing device runs obliquely from the front/bottom upwards/rearwards towards the ceiling of the refuse-collecting container and a projection, which causes a reduction in the cross-section of the container opening, is provided on the floor of the refuse-collecting container in the region of said opening. As a result of the chosen direction of action, the refuse can be compressed in the region of the overall cross-section of the refuse-collecting container and against the ceiling at an early stage, resulting in optimum utilisation of the overall volume of the refuse-collecting container. The projection on the floor of the refuse-collecting container furthermore prevents undesired discharge of the refuse through the container opening. <IMAGE>

Abstract: A processor (10) operable to calculate division and square root functions comprises a multiplier (48) having a multiplier array (116), a pipeline register (50), a correction generator (122), and a converter/rounder (52). The products generated by the multiplier array (116) are fed back to the multiplier (48) to avoid delays associated with the remainder of the multiplier circuitry. The correction generator (122) which performs a subtraction of the product output from the multiplier array (116) from a constant, is disposed between the multiplier array (116) and the converter/rounder (52). Hence, the subtraction necessary to compute the next estimate may be performed in parallel with other multiplications, further reducing the time necessary to perform the calculation. Compare circuitry (120) is operable to compare the final approximation with an operand to quickly determine the direction of rounding.

Abstract: Upon the adjustment of a control setting of a test instrument, the current data (taken before the change is effected) is manipulated by recalculating the trace data in light of any adjustment that is entered by a user. This represents an estimate of the effect of the adjustment in the control setting, and this estimate is redrawn on a display device. This modified image is preferably displayed before the real new image is ready to be displayed. This provides immediate feedback to the user so that adjustments can be effected without slowing the measurement process. Various embodiments provide panning or repositioning the trace left and right while changing the x-axis center frequency; stretching or compressing the trace (spanning) while changing the frequency span; or using a combination for adjustments to only the start or stop frequency. In one embodiment, the estimate can be displayed only after the user has committed to having a new measurement performed. Alternatively, in another embodiment, estimates can be displayed continuously while the user is making adjustments and before the user has committed to performing a new measurement. Having a test instrument display to the user an estimate of a future measurement while adjusting the control settings of the instrument in order to aid knob and button settings facilitates making adjustments visually during measurements which take longer than a fraction of a second. By having an immediate response on the display device, the user is not required to make blind changes.

Abstract: A colored ceramic glaze is prepared from a raw glaze containing glass frit, clay and one or more cera­mic pigments added as an aqueous dispersion. The raw glaze is ball-milled after which it is blended with the aqueous dispersion. The dispersion contains up to 70% of a ceramic pigment, such as zirconium-vanadium yellow, preferably with 1% to 3% of a suspending agent, up to about 1.5% of a thickener, an effective amount, but no more than 1% of a dispersant, and a biocide as needed. The suspending agent preferably is attapulgite clay or a water-swellable smectite clay. The thickener is prefer­ably a xanthan gum and the dispersant is typically an ammonium salt of a medium molecular weight polymethacryl­ic acid. A stronger, more intense color is achieved by adding the ceramic pigment as a dispersion as opposed to ball-milling it with the glass frit as has been the traditional approach.

Abstract: A fluidizing centrifugal pump (10) for medium to high consistency fiber suspension includes a housing (14) having an inlet channel (16) and an outlet (18) and an impeller (12) operatively rotatable about the pump axis (34). The impeller (12) has a working vane (36) and at least a blade (40) extending substantially axially from the working vane (36) and disposed in the inlet channel (16) for fluidizing suspension which is received in the pump inlet (16). A feeding (44) vane, preferably in the form of a spiral thread, is disposed in the inlet channel (16), radially-outwardly from the fluidizing blade (40) and extending along at least a portion of the axial extension of the blade (40). The feeding vane (44), which may be operatively rotatable with the impeller (12) or stationarily fixed to the pump housing (14), provides axially-directed feeding of suspension through the inlet channel (16) toward the working vanes (36), concurrent with fluidizing of suspension in the channel (16) by the impeller blade (40), thereby effectively preventing reverse flow of suspension in the inlet channel (16) and correspondingly increasing the operating efficiency of the centrifugal pump (10).

Abstract: An optical head in which reflected laser light is split into two optical paths by a polarized light beam splitter (23) while astigmatisms are produced in the laser light by at least one astigmatism generating element (22), and the two split beams are led so as to be incident upon two quadrant photodetectors, respectively. A focus error signal is obtained as an electrical signal by subtracting the sum of the quantities of light received by one of the diagonal pairs of regions among the quadrant regions of the two photodetectors (24, 25) from the sum of the quantities of light received by the other diagonal pair. This arrangement enables cancelling of influence of double refraction in a magneto-optic disk or the like, thereby making the optical head free of the problem of such influence.
