Abstract: The invention relates to a gearing for winding-up and unwinding a roller shutter consisting of several slats, which is mounted in a roller shutter box (3) or on two lateral shells (2) via a roller shutter cylinder (4), and the roller shutter box or the shells being mountable on the masonry or the like. The gearing comprises an inlet opening in a gear wheel for the insertion of an input rod to be operated manually or with a motor and an outlet opening in a gear wheel for the insertion of an output rod, which leads to the roller shutter cylinder or a roller shutter gearing preceding said cylinder. When starting from a known gearing of this type, to allow still further adaptation by the fitter to various soffits and installation conditions of the windows or doors at the construction site, i.e. in situ, corresponding to the particular conditions there, at least three intermeshing gear wheels are provided which each have an inlet or outlet opening (7, 8, 9) for the insertion of the input rod (10) or the output rod (6), the gearing (1) has a flange (11) for its releasable attachment to the roller shutter box or the lateral shell (2) and said flange is mounted at a point on the gearing situated outside the centre of the gearing (as seen in its longitudinal direction). <IMAGE>

Abstract: A point-of-sale credit card verifier (1) for checking the validity of cards, such as credit cards, comprises means for non-destructively storing information (3) on invalid credit cards for comparison with information which is read from a card presented for use. The information on invalid credit cards is transmitted by signals embedded in a VHF stereo radio broadcast from a broadcast station which is received by a VHF receiver/demodulator (10). A credit card sensor (4) and control maintains the verifier switched off unless a credit card is to be read. The verifier is switched on when information is about to be broadcast from a broadcast station. The verifier operates quickly and independently of telecommunications networks.

Abstract: A circuit is disclosed in which the effect of ambient noise on the voice control in a hands-free subset is greatly reduced. Frequency components of the ambient noise which lie outside the voice-frequency range are determined on a selective basis and are used, together with the voice levels of the two transmission paths of the subset, to control the send path. The control signal selectively derived from the ambient noise counteracts the control by the voice level of the send path. In the simplest case, it is derived via a filter (12, 18) designed to pass the desired frequency range, an amplifier (13, 19), and a sign-reversing rectifier stage (14, 20) whose output is combined in an adder (11) with the control signal derived from the voice level.

Abstract: Disclosed is the solidification and chemical fixation of liquid wastes using biogenetic primarily amorphous silica to the waste in the presence of a strong alkali in the waste which converts the biogenetic silica into a soluble silicate, and in the presence of a polyvalent metal ion in the waste which reacts with the soluble silicate to provide a cementitious product of the waste. In the event there is insufficient strong alkali present in the waste to convert the biogenetic amorphous silica to a soluble silicate, and insufficient polyvalent metal ion in the waste to harden and form a cementitious product, amounts of these components as necessary can be added along with the biogenetic silica to the waste. The resulting cementitious and chemically fixed waste can be left in place, for example to provide a land farm, or can be removed and broken up and used as a cover for land fills, various land applications, and farms, as well as other applications.

Abstract: The expanding cone (1d) of an expanding dowel, consisting of an anchor bolt (1) and an expanding sleeve (2), has a cone angle (alpha) which is larger than the cone angle (beta) of the hole (2d) (which enlarges towards the front end (2a)) of the expanding sleeve (2). The expanding sleeve (2) is provided with a circumferential annular bead (2e) in the expanding region. The wall thickness of the expanding sleeve (2) reduces in the expanding region in the circumferential direction to the longitudinal slots (2c). As a result of these measures, it is achieved that the expanding sleeve (2) is expanded very sharply at the start of the expansion process and the annular bead (2e) is pressed into the wall of the hole. The positively locking connection, produced in this way, of the expanding sleeve (2) to the supporting material permits the use of the expanding dowel even in tension zones of a building where there is a risk of cracking.

Upon actuation of a servomotor, a valve is opened so that the pressure at the corresponding end of the spool decreases causing a shift of the spool in that direction. The servomotors are triggered by brief electrical digital signals.
