Abstract: An ion-selective electrode for measuring carbonate concentration comprising a conductive metal layer (2), a halide of said conductive metal layer (3), a carbonate ion-selective layer (4) containing ion carrier, and a buffer layer (5) containing a hydrophilic polymer binder and a buffer laminated in this order on an electrically insulating support (1), and a pair of the above electrodes. 
     It is characterized by not having the electrolyte layer containing hydrophilic polymer binder, having the possibility of degradation of the electrolyte layer by the absorption of moisture being extremely little, and having a good stability in the course of time. In the electrode of the invention, the ion-selective layer comprised of hydrophobic organic material is directly laminated on the metal halide layer, the adhesive strength between the metal halide layer and the ion-selective layer is sufficient, the strength of the ion-selective layer is sufficiently great, and which is stable. The electrode of the invention has a sufficient buffering ability, and it requires neither operation of preliminary measurement of the pH value of aqueous liquid sample nor fixation of the pH value by adding a pH buffer to sample. Moreover, the adverse affect   (measuring error) by the interfering substance such as salicylate, p-aminosalicylate or gentisate is eliminated or remarkably reduced.

Abstract: A bit oriented communications network includes a plurality of nodes (10, 11) interconnected by a broadcast communications medium (20). Each node (10, 11) samples inputs (17) connected to it and broadcasts the values of those inputs. All of the nodes then monitor the broadcasts and map selected bits to outputs (18) connected locally through an output mapping process. Connections are established between inputs (17) and outputs (18) by the output mapping process, which in a first described embodiment functions by maintaining a map address, which specifies a selected node and a selected input value within that selected node. The output mapping is then performed by monitoring the broadcasts until the broadcast from the selected node is heard, and then extracting the selected input value from that broadcast and routing that input value to an output bit. A "connection" is thereby established between the output and the selected input, and such connections may be changed simply by changing the output mapping selections. 
     Both the input and output bits may be either physical devices (14, 15, 16) or, as described in a second embodiment, may be exchanged with an external system (31, 33, 34, 35, 36, 37, 38) through a shared memory (30). 
     A Dynamic Time Division Multiple Access (DTDMA) time slot allocation scheme is used to synchronize transmissions from each node (10, 11) in a round robin fashion. Each node is allocated one time slot for transmission and maintains a current time slot value in a gap timer. The gap timers of all nodes are synchronized by monitoring a source address field in the round robin broadcasts.

Abstract: A magnetic data storage system for use with a double sided disk in which a prerecorded pattern of opaque optical lines is used to define the tracks in which magnetic data is to be stored. A separate optical system including an illumination source and a photosensitive detector is provided on a read/write assembly for each side of the disk. Each detector is designed also to serve as a reference grating. The illumination source is designed to image the prerecorded pattern of optical lines on the reference grating as an indication of the alignment of the read/write head of the assembly and a desired data track and any misalignment of the head and track generates a servo signal. The detector uses four separate photocells interleaved in a prescribed fashion to form a quadrature detector that is adjustable to compensate for various non-uniformities. One form of illumination source uses a surface-emitting light emitting diode and optics for forming a multiple beam source.

Abstract: A strip-like concrete reinforcement spacer (1) with a bearing strip (2) and two supporting strips (3, 4) integrally moulded thereto to form a U-shaped cross-section is described. At least one longitudinal rib (14 and 15), which is approximately 2-4 mm high and is provided with transverse grooves (17 and 18) at regular spacings, is integrally moulded on the bearing strip, on its side opposite the supporting strips. When placed in the transverse grooves in the longitudinal rib or ribs, the steel reinforcing elements (9, 10) are very well stabilised against lateral slipping. Since the transverse grooves are arranged at regular spacings, the desired uniform spacing of the steel reinforcing elements from one another results automatically. The complex measuring of the spacings and the complex aligning of the steel reinforcing elements on the building site are no longer necessary. Moreover, the low height of the longitudinal rib(s) of only 2-4 mm and consequently the correspondingly low depth of the transverse grooves ensure that spacings other than those predetermined by the sequence of the transverse grooves can also be chosen. <IMAGE>
