Patent GB-2136613-A (GB)
Title: Data recorder with non-volatile solid state memory
Inventor: JERRIM JOHN W
IPC: G06Q30/00
Filed: 1984-01-18
Abstract: An electricity billing recorder has a controller for processing pulses from an electric meter. The resulting data is temporarily stored in random access memory as data words representative of energy consumed in predetermined time ("demand") intervals. The accumulated measurement ("event") data and time data are transferred to a non-volatile, solid state memory module after relatively long collection periods comprising a number of demand intervals. The solid state memory is energized only during data transfers. The entire memory module is replaceable for processing at a central location. During replacement the controller writes a special Removal Record in predetermined locations on the memory module being removed, and prepares a special Insertion Record for the new module. The cumulative counts recorded on these special records in addition to the normal records establish reliable data continuity. After any collection period in which a power outage has occurred, the controller transfers the current data to a secondary portion of RAM. Subsequent demand intervals, until power is restored and including any memory thermal recovery periods, are assigned chronological index numbers and event data is stored only for those demand intervals in which power consumption actually occurs. After return to normal operation, the data in secondary RAM is transferred to the solid state memory and the compact format data in primary RAM is re-constructed into normal storage format with all intervals during which no event data was stored being zero filled. As this data is transferred to secondary RAM for storage in the solid state memory, the remaining data in primary RAM is re-located to provide as much space as possible for data storage should another power outage occur before conversion of all the compact format data. <IMAGE>
Patent GB-2155008-A (GB)
Title: One solvent process for preparation of esters of 3,5-dibromo-4-hydroxybenzonitrile
Inventor: SHEADS RICHARD ERIC
IPC: C07C255/49
Filed: 1984-02-29
Abstract: Esters of 3,5-dibromo-4-hydroxybenzonitrile can be prepared in high yields from 4-cyanophenol in a single halogenated alkane solvent. In this manner, the 3,5-dibromo-4-hydroxybenzonitrile intermediate need not be isolated, and therefore the bromination and esterification reactions can be performed in one reactor. Preferably, the bromination is accomplished with bromine chloride in the presence of 1,1,2-trichloroethane followed by esterification with an acid chloride in the same solvent.

The frame members comprise a polyphenylene sulfide resin; polyether sulfone resin; or mixture thereof; and a filler. The frame members are preferably injected molded at a melt temperature of about 600 DEG F (316 DEG C), and a mold temperature of about 290 DEG F (143 DEG C) using pressure of about 10,000 psi (703 kg/cm<2>) and a mold cycle time of about 35 seconds. Following molding the resin is cured at about 425 DEG F (218 DEG C) for about 3 hours. Design features may be molded into the frame during processing by utilizing a sophisticated mold that incorporates the desired features or these features may be machined into a plain frame that has been molded. The molded frames are simpler in design and manufacture and weigh less than multilayer laminates. In addition, the materials utilized are stable in alkali environments and contribute less contaminates to a cell resulting in greater cell durability. <IMAGE>

Abstract: A resonant sensor 1 is optically powered and read along a single optical fibre 18. A band stop filter 20 at the frequency of the power signal from a source 12 prevents it from reaching the reading system. The resonance causes modulation of light reflected from the vibrating element 10 and this modulation gives a measure of the parameter being measured, eg a force F. A pulse timing circuit 10 adjusts the modulation frequency of the source 12 to be equal to the resonant frequency of the element 1B and the sensed parameter is displayed at a device 21. <IMAGE>
