Abstract: The lamp is of compact construction and has high illumination efficiency and good colour properties. It is suitable for general purpose lighting tasks, has a colour temperature in the range 3000 to 4000 K and can be designed for a wide power range and in particular also for very low powers. A discharge in caesium or rubidium is used, the plasma of which is heated with high-power pulses of high repetition frequency and low pulse-duty factor until the recombination continuum distributed over the visible spectral range is being emitted with high intensity and this intensity exceeds that of the line spectrum radiation in the spectral ranges that are ineffective for illumination purposes. <IMAGE>

Abstract: There are disclosed normally tacky, pressure-sensitive adhesive compositions comprising one or more normally tacky polymers having a Tg of about 0 C. or less and containing pendant functional groups attached to the backbone and having the formula:
     in which R 1  is a divalent organic radical at least 3 atoms in length, and X is organoacyl or cyano, the polymers preferably also being normally tacky when cured. Such polymers have markedly improved cohesive strength (shear holding value) with little or no detriment to adhesive tack or adhesion (peel resistance), and these improvements are realized without the necessity of incorporating cross-linking monomers such as N-methylolamides or other cross-linking agents. Pressure-sensitive adhesive, water-based emulsions containing such polymers and pressure-sensitive adhesive articles comprising a substrate having at least a portion of one surface thereof coated with the adhesive compositions are also disclosed. In a preferred embodiment, the adhesive compositions further include a polyacid component for further improving cohesive strength, particularly at acidic pH.

Abstract: The oscillation frequency of a voltage controlled oscillator (4) is controlled by setting a division ratio of a variable ratio divider (2) provided in a feedback path of a phase locked loop. When the frequency is switched by changing the division ration a steering voltage (Vda) is applied to the voltage controlled oscillator. This steering voltage can compensate non-linearity so as to reduce the frequency errors and phase errors after switching to thereby enable high speed frequency switching.

Abstract: A completely continuous process for reacting a substrate solution on an immobilised biocatalyst is described. For this purpose, the substrate solution is reacted on the catalyst with enzyme activity in a tubular reactor, the catalyst migrating along the tubular reactor, through which the substrate solution flows, in such a way that an activity profile which is essentially constant with time is maintained along this tubular reactor. This process makes it possible to maintain a substantially constant space velocity of the substrate solution and a uniform product flow with essentially constant degree of conversion.
