Abstract: ABSTRACT OF THE DISCLOSURE    Rapid setting magnesium phosphate (Mg glass) cementitious materials consisting of magnesium phosphate cement paste, polyborax and water-saturated aggregate exhibiting rapid setting and high early strength characteristics.  The magnesium glass cement is prepared from a cation-leachable powder and a bivalent metallic ion-accepting liquid such as an aqueous solution of diammonium phosphate and ammonium polyphosphate.  The cation-leachable powder includes a mixture of two different magnesium oxide powders processed and sized differently which when mixed with the bivalent metallic ion-accepting liquid provides the magnesium glass cement consisting primarily of magnesium ortho phosphate tetrahydrate, with magnesium hydroxide and magnesium ammonium phosphate hexahydrate also present.  The polyborax serves as a set-retarder.  The resulting magnesium mono- and polyphosphate cements are particularly suitable for use as a cementing matrix in rapid repair systems for deteriorated concrete structures as well as construction materials and surface coatings for fireproof structures.

Abstract: ABSTRACT         In the desulfurizing method for removing sulfurous ingredients from combustion exhaust gases by contacting the combustion exhaust gases with a desulfurizing agent as heating medium in the form of fluidized bed of a fluidized bed combustion furnace, successful desulfurizing results can be obtained by using as the desulfurizing agent a hardened material whose particle size is 0.7 to 2 mm, prepared by mixing 10 to 70% by weight of cement with limestone or dolomite and hardening by adding water.  The improved method shows high desulfurizing efficiency and stability.

Abstract: FORMING CABLE CORE UNITS          Abstract of the Disclosure Making a cable core unit in which pairs of twisted conductors are formed upon individual twisting machines, the twisted conductor pairs then fed 'in-line' to a core forming device by passing the pairs through a tension reducing means which reduces tension in each pair while allowing the lengths of the pairs to be different from pair-to-pair as they move into the core forming device.  Built-in tensions and twisted core units are thus avoided.  Also provided is a tension equalizing device which averages out the tensions between conductor pairs.

Abstract: ABSTRACT OF THE DISCLOSURE    A linear detector  (31) for use in a coarse positioning servo system of  an  optical  disk  storage  system.   The  linear  detector produces  an  error  signal  (67)  having  an  amplitude  linearly proportional  to the distance that  a  center  of mass  of  incident radiant  energy  (63)  falls  on  a  collection  surface  (62)  of  the detector as measured relative to a fixed reference point on said collection surface.  Two reference signals (65, 66) are derived from circuitry associated with the collection surface.  A first reference signal (65) has an amplitude proportional to the intensity of the focused light energy and the location that said light energy falls on the collection surface relative to a first reference point.  A second reference signal  (66) has an amplitude proportional to the intensity of the focused light energy and the location that said light energy falls on the collection surface relative to a second reference point.  The sum and difference of the amplitudes of the first and second reference signals are derived to produce sum and difference signals (Y, X), respectively.  The difference signal is divided by the sum signal (X/Y) to produce the desired error signal, which  error  signal  has  an  amplitude  that  is  substantially independent of the intensity of the focused light energy.  Signal processing circuitry (84, 86, 88; and 85, 87, 89) may be used to demodulate the reference signals so that the desired error signal is derived  only  from that  portion  of  the  incident  radiant  energy reflected from a coarse servo track of the optical disk,  and not from radiant energy reflected from other areas of the disk.

Abstract: ABSTRACT OF THE DISCLOSURE             An enthalpy measuring arrangement for measuring the heat content of a substance which may in the liquid phase, vapor phase or a mixed phase of liquid and vapor, comprises a first enthalpy calculating module for calculating the enthalpy of the substance when in a two-phase condition utilizing a plurality of discrete function blocks.  The specific volumes of the overall mixture is calculated using a density transmitter which measures the density of the substance.  Tables are utilized to obtain the specific volumes of the gas and vapor part of the substance on the basis of  a  measured temperature for the substance.  These values are in turn used to obtain a quality value which is multiplied by a value representing the difference between the enthalpys of the vapor and liquid components of the substance to obtain the overall enthalpy of the mixture. Another module with a plurality of function blocks generates the enthalpy of the substance when it is superheated or entirely in the vapor phase.  A selector module is connected to the mixed and vapor phase calculating modules to determine which of the modules should be utilized and to calculate the overall enthalpy of the substance regardless of its phase.

Abstract: FLEXIBLE CORRUGATED RUBBER TUBING    WITH INTERNAL REINFORCEMENT     ABSTRACT OF THE DISCLOSURE          A method for making flexible, corrugated rubber tubing with internal reinforcement.  An extruded sleeve of uncured rubber is slid axially onto an elongated internal forming member, after which an external forming means is placed around the assembled sleeve and used to form corrugations.  The resulting product is heat-treated to set the corrugations and thus to form a flexible cor-rugated tube length.  A helix formed of flexible, resili-ent wire rod is pulled through the corrugated tubing in an axial direction and simultaneously rotated in a direc-tion to thread the helical rod into the internal hellcal groove in the sorrugated product.  At the same time, the helix is axially extended to reduce its helix diameter. When the helix has been completely extended through the corrugated tubing, it is released so that it expands radially into tight conformance with the internal helical groove.

Abstract: ELECTRONIC DEMAND REGISTER            ABSTRACT OF THE DISCLOSURE         An electronic demand register includes a processor for calculating a demand in a demand subinterval.  At the end of each demand subinterval, the calculated demand is summed with the demand in the preceding N-1 subintervals to derive an interval demand over N contiguous subintervals.  The interval demand is compared to a previously recorded maximum demand and, if the interval demand exceeds the maximum demand, its value is substituted for the maximum demand for use in subsequent comparisons.  The processor employs volatile memory.  A non-volatile memory is provided for storing the billing data and programmed constants in the event of an impending power outage.  A power monitor detects the possibility of an impending power outage and, operating on stored energy, both enables and powers the transfer of data to the non-volatile memory.  When power is resumed, the power monitor enables resetting the processor and retransferring the data from the non-volatile to the volatile memory for resumption of demand metering.  A grace period is provided after the resumption of power before beginning demand metering to permit the energy user's starting loads to pass before demand metering begins.  Provision is made for treating the beginning and ending of a test operating mode similar to a power outage.  In addition, the demand register responds to its removal from, and its replacement in, the electric meter in a manner similar to its response to a power outage.  In this manner, when the demand register is removed from the electric meter, the billing and other data is safely stored in the non-volatile memory from ABSTRACT OF THE DISCLOSURE                    (Cont'd) which it can be copied to a replacement demand register.  When the original or replacement demand register is replaced in the electric meter, the demand register treats the replacement in the same manner that it treats the resumption of power following a power outage.

The antifreeze composition is a consolute antifreeze composition having a cloud point of at least about 40°C, whereby when the temperature of the antifreeze is raised to at least the cloud point of 40°C, the oil in the consolute antifreeze composition becomes insoluble.  The insoluble oil separates from the antifreeze composition and coats the metal surfaces of the internal combustion engine, thereby imparting a corrosion inhibition property to said antifreeze composition with respect to said metal surface.
