Abstract: The telephone subscriber filter has a blocking filter (5; 5') which keeps the charge pulses which arrive via the exchange line with frequencies in the vicinity of the upper voice band limit, preferably around 4 kHz, away from the telephone device and which comprises a reactance filter in the form of a chain circuit with the structure of an impedance-balanced filter; it is, however, designed on the telephone device (2) side for a complex termination comprising an 800-1000  OMEGA  ohmic resistor (R2) and a 30-50 nF capacitor (C2) connected in parallel with it and on the exchange side for a real termination with a 1000-1200  OMEGA  ohmic resistor (R1). A frequency converter (9) is connected downstream of the charge pulse receiving circuit (6') which converts the charge pulse frequencies into a frequency of 12 or 16 kHz which is suitable for conventional high-frequency metering and whose output on the blocking filter (5') side facing the telephone device (2) is coupled with the speech wires. <IMAGE>

Abstract: The free end portion of the boom of a crane carries a separable pivot bearing defining a horizontal pivot axis for a second bearing which reciprocably guides an upright column for one or more galleries. When the cable which is used to lift or hold the column breaks and the column begins to rapidly descend, such movement of the column activates a composite brake mounted on a frame surrounding the column at a level above the second bearing. The brake holds the column against downward movement with reference to the frame whereby the frame tends to descend toward the second bearing against the opposition of several shock absorbers which reduce the likelihood of damage to and/or excessive swaying of the boom and/or injury to the occupant or occupants of the gallery. The speed of downward movement of the column is monitored by a detector which activates the brake as soon as the speed exceeds a preselected value.

Abstract: Air bars 12 extending lengthwise parallel to one another are mounted on the front of a plenum chamber 10 with their front walls 28 lying substantially on an arc around which a moving web W is guided. Each air bar 12 has a pair of elongate Coanda nozzle outlets 29, extending along the opposite longitudinal edges of its front wall 28, through which pressurised air from the plenum chamber 10 emerges as streams that converge across the front wall 28 and which support the web W without contact between the web W and the front wall 28. Plates 44 extend between the pairs of adjacent air bars and these plates 44 have their front surfaces on an arc concentric with the arc of the front walls 28 but of smaller radius. An air dam 117 at each end of each plate 44 restricts the flow of air from beneath the web W in the lengthwise direction of the plate 44. Further air dams 45, adjacent each edge of the web W, prevent excessive spillout of pressurised air from beneath the web W. <IMAGE>

Abstract: A heat transfer medium, e.g. engine coolant, flows through the heating element 3, 4 of a heating and/or air conditioning system in a motor vehicle. A temperature responsive controlled timing valve 10 controls the flow in response to temperature sensors 12, 13, 14 and set point adjusters 15, 16. A throttle not operatively connected to the valve 10 is varied with the set- point adjusters 15, 16 in such a manner that, starting from a position II in which the set point temperature is easily reached, the throttle cross-section is continuously enlarged until the fully open position of the heating is reached. This makes it possible, particularly if the desired temperature is reached, and without reducing control accuracy, for the proportion of time during which the valve 10 is open to be still high even if there is only a slight flow of heat transfer medium because of the restriction of the throttle. Detrimental pressure surges and cold blowing are thus avoided. <IMAGE>

Abstract: A plant for growing fish comprises a number of adjacent pools (23) to which water is supplied at one end and which, at the other end, have a water outlet in the form of a narrow gap close to the bottom. Since the depth of the water in the pools (23) is relatively small, the fish are forced to move close to the bottom and, by their fin movements, keep the waste collected on the bottom in motion and cause it to move with the flowing water to the outlet opening into a space (20), the bottom of which is situated at a lower level than the bottom of the pools (23). The space has an overflow edge on a level with the water surface in the pools, thus causing the waste coming through the outlet to sink down to the bottom of the space from where it is conducted to a purification plant (38, 39), while clean water flows upwards over the overflow edge to an outlet duct (40) from where it is discharged into a lake or water course and/or recycled to the pool inlet.

Abstract: Copolymers of acrylic or methacrylic materials of known type and reacted with novel, silicone-substituted acrylic and methacrylic compounds so as to produce an oxygen-permeable plastic material which is uniquely suitable for manufacturing novel corneal contact lenses. The silicone materials include high molecular weight polysiloxanylalkylesters of acrylic and methacrylic acids, made from acrylic or methacrylic ester silanes containing one or more highly substituted siloxanyl groups. One such siloxane substituent, pentamethyldisiloxane, is prepared by a novel method. Certain of the substituted silanes are prepared using a novel compound, tris(trimethylsiloxy) acetoxysilane. The polymers made from the combination of novel and known monomers are highly permeable to oxygen and can be used to make lenses, including bifocal lenses, which are thick enough to be rugged, hard enough to provide dimensional stability, and optimum optical correction, and sufficiently permeable to oxygen to provide extended duration wearing capabilities. A number of novel monomers are disclosed. The polymers may be made from known monomers and individual novel monomers, or from the known monomers or mixtures thereof and mixtures of the novel monomers. The finished polymers may also include conventional additives such as wetting agents and cross-linking agents.
