Abstract: A lenticular light-transmissive viewing screen, such as a projection television screen, has grooves (18) in between the lenticules wherein light absorbing particles (28) are deposited. The particles are affixed to the screen and to each other by selectively heating them by generally applying microwave radiation (30) to the screen, for which the particles have a higher absortion coefficient than the screen material. The particles are selectively deposited in the grooves by electrically charging the lenticule peaks and depositing particles charged with the same polarity to effect repulasion by magnetically attacting the particles to the tips of a particle carrier sheet (40) which positionally correspond with the grooves in the screen and subsequent releasing of the particles in the grooves or by applying a slurry (64) comprising a mixture of a volatile liquid and the light-absorbing particles.

Abstract: In regulating a burning gas quantity of a gas combustion apparatus, a gas flow controller is used. The gas flow controller is constructed such that a closing member (36) within a cock (35) is rotated by using a motor (50). The closing member has a plurality of holes (38, 61) formed in the axial direction of the member and a plurality of grooves (39, 62) each corre­sponding to the hole and formed in the circumferential direction of the member. The cock is used for changing, opening and closing a plurality of orifice passageways (40, 63). The motor is driven in accordance with a signal from a position determining unit (53) which discriminates the position of the cock. The gas flow controller can advantageously ensure a high precision of gas flow, a high reduction ratio, and a low power consumption.

Abstract: At least two contact pairs, a gear wheel and a leaf spring are provided in a pulse generator, the end of the leaf spring engaging in a latching manner in a tooth gap of the gear wheel, in the quiescent position. After each rotation angle, corresponding to one tooth pitch, after deflection by a tooth, the end of the leaf spring springs into the next tooth gap in a latching manner and, depending on the direction of rotation of the gear wheel, one of the contact pairs can be switched per tooth pitch in each case once. To avoid missing pulses, or additional pulses as a result of contact bouncing, one of the contact pairs (33, 35; 33, 36; 34, 37; 34, 38) is arranged on each side of the leaf spring (12). Movable transverse slides (17, 18) are assigned to the leaf spring (12) such that, when the gear wheel (7) rotates in the one direction of rotation, the first transverse slide (17) can move, and the first contact pair (34, 37 and/or 37, 38) can be operated, and the second transverse slide (18) remains in its quiescent position, and such that, on rotation of the gear wheel (7) in the other direction of rotation, the second transverse slide (18) can move, and the second contact pair (33, 36 and/or 33, 35) can be operated, and the first transverse slide (17) remains in its quiescent position. In addition, such a pulse generator is of compact construction and can be produced economically.

Abstract: In order to obtain cell cultures in relatively large quantity, it is necessary to detach the cultures in each case from the microcarriers and transfer them to unoccupied microcarriers. To date this has been carried out intermittently by adding trypsin, which causes detachment of the cells, to a container with colonised microcarriers. A high percentage of the cells detaches rather rapidly and thus remains a long time in the trypsin solution, which has an adverse effect on these cells. 
<??>In the process, the trypsin solution is passed in a continuous flow process through the container and thus through the microcarriers. Detached cells are therefore immediately flushed out of the container, and the trypsin solution is inactivated and/or separated out after leaving the container. 
<??>The process can be used for growing cell cultures on microcarriers.

Abstract: A microwave plasma CVD apparatus comprising a hermetically sealed vacuum vessel (27), an evacuating means for evacuating the vacuum vessel, and microwave introducing means (21) for introducing a microwave through a microwave transmission circuit into the vacuum vessel to produce a plasma within the vacuum vessel. The microwave transmission circuit includes a cavity resonator (22) integrally provided with two matching circuits. The microwave plasma CVD apparatus solves all the problems in the conventional microwave plasma CVD apparatus, operates at a high rate of operation, improves working efficiency, reduces the manufacturing cost of a-Si devices, and reduces variance in performance between devices employing films deposited by the microwave plasma CVD apparatus. Since the microwave plasma CVD apparatus does not employ any large electromagnet, a film can be formed on a surface having a large area simply by selec­tively deciding a microwave propagation mode. Since the distance between the cavity resonator and the coupling hole can be varied, the microwave input impedance can always be matched regardless of the sectional area of ionization, so that microwave power is used effectively and the gases are used at a very high efficiency.

Abstract: Method for mutual data communication between a communication exchange and a staff presence detection installation. The aim is that a mutual exchange of data and information items occurs between the systems, as a result of which mutual influencing is possible and staff-related information items are transmitted to the terminal. In addition, it should be possible to store additional information items on the presence or absence of the associated staff, allocated to the connection elements, in a main memory of the communication exchange. As a result, additional information items should be available during the setting-up of connections and at switching stations. When a terminal of the staff presence detection installations is operated, a data transmission occurs to the communication exchange so that certain features can be changed. In addition, subscriber-individual information items which have been produced in the communication exchange are transmitted to the staff presence detection installation so that they can be output at a terminal connected there when an input occurs there. In an incoming/outgoing message at a terminal of the staff presence detection installation, an identification signal is transmitted to the communication exchange which is stored in a main memory in the area which is associated with the connection element allocated to the relevant person. In this way a determination and indication of the presence or absence of associated persons is effected in addition to the determination and indication of the idle/busy state of connection elements which is usual in communication exchanges. The interaction of communication exchange and staff presence detection installation provides the possibility of optimally adapting features of the communication exchange in dependence on the presence or absence of persons. Person-related information items can then selectively reach the correct address when the relevant person operates a terminal of the staff presence detection installation. Since the communication exchange additionally has the information on whether subscribers are present or absent, the operating convenience can be considerably increased in that a calling subscriber or an operator can be informed on whether a subscriber can be reached or not. <IMAGE>
