Abstract: The present invention relates to a system for channel-specific releasing and blocking of telephone channels in "outgoing" signaling converters and in "incoming" signaling converters of a pulse code modulation (PCM) system. Alarm signals which influence the signaling converters are generated in monitoring devices. The first alarm signal serves for accommodating the signal transmission and occurs immediately given faults in the system and occurs delayed given disturbances in the system. The second alarm signal effects a blockage of the telephone channels with respect to new seizure and is immediately triggered given disturbances in the system and given faults in the system. Given this method of alarm, a channel-specific and time-differentiated release and blocking of telephone channels occurs independently of the presence of a central processing device in a signaling converter equipment.

Abstract: An electronic control system for a machine tool employs a monitoring system for monitoring the absolute position of a reversibly (and linearly or rotationally) movable moving member in the machine tool. The monitoring system includes a clock, a digital feedback position counter having a predetermined count range, an exciter, a feedback device responsive to movement of the movable member, a digital position storage device, a zero crossing detector, and a zero position counter. The feedback position counter, which operates at a clock frequency, controls the exciter which provides a pulsed exciter signal to the feedback device. The feedback position counter also provides a position count Nc to the position storage device and to the zero position counter. The feedback device provides, through a zero crossing detector, a pulsed feedback signal to the position storage device (and to the zero position counter) and the phase shift between the exciter signal and feedback signal is linearly related to the displacement of the moving member. The position storage device provides a continuously updated position number Np which is also linearly related to member displacement, i.e., the position of the member. The zero position counter typically comprised of a synchronous 4-bit bi-directional binary counter provides a zero position count Nz to the representative of the net number of times the position number Np passes through zero between consecutive samples. A computer, coupled to the position storage device and to the zero position counter, processes the position number Np and the zero position number to unambiguously determine the speed of the moving member.

Abstract: A mechanism is provided for saving substantial time when a service processor needs to communicate with one of a plurality of satellite devices, but does not know the identity of the specific device. The service processor, through an intermediate adapter, issues a command which addresses the class of devices. The adapter redirects the command to the specific device, and concatenates the response from that device along with the device's identity and forwards this to the service processor. Further communication between the service processor and the specific device can then take place directly.

Abstract: A method of reducing the calcium concentration of aqueous solutions which comprises contacting the solution, preferably at an elevated temperature, with magnesium carbonate which preferably has been freshly prepared. The amount of the magnesium carbonate is such as to effect substantial precipitation of the calcium as a calcium containing carbonate. The carbonate can either be left with the solution to stabilize it against pH shifts, for example in the extraction and processing of beet sugar, or can be separated from the solution, as where the presence of the calcium containing solid is objectionable, such as in boiler feed water treatment. The method is also useful in reducing calcium concentrations in sea salt solutions during recovery of table salt, in preventing scaling in boiler water and in the production of products where process conditions are sensitive to calcium levels.

Abstract: A packer element, for use in a pack-off device in well bores that may be at a relatively low initial temperature and be subsequently heated to much higher temperatures, comprises a plurality of high temperature packing segments (68, 70, 72) and one or more low temperature packing segments (69, 71) each disposed between two high temperature segments. High temperature packing material of asbestos fibers impregnated with Inconel wire is preferably employed In packer rings (68, 70) of frusto-conical shape which face on a center packer ring (72) of triangular cross-section formed of the same material. Low melting point thermoplastic wafers of frusto-conical shape are interspersed at least between adjacent frusto-conical packer rings. These thermoplastic wafers soften at a relatively low well bore temperature and help to initiate a seal when squeezed between the high temperature rings as the packer is set. As the well bore temperature increases, the low melting point thermoplastic liquefies and is squeezed out from between the high temperature packer segments, which then take over the sealing function.

Abstract: A system is provided for measuring the shape of sheet stock within a rolling mill (12, 14). The system includes a shape sensing roll (18) including a plurality of roll segments (52). Each segment includes a magnetic bearing (46, 48, 50, 52, 54, 56), the stators (46) thereof being mounted to a stationary shaft (34). The bearing rotors are mounted in a steel ring which contacts the strip to be measured. Each roll segment is suspended by a magnetic bearing which is free to react to the loading placed thereon, independent of adjacent segments. Since the magnetic bearing system automatically regulates the power supplied to the electromagnets of the respective bearings to maintain their concentric positions, changes to the power inputs are a direct indication of the magnitude of the loading thereon.
