Filed: 1973-06-26
Abstract: 1391756 Measuring torque electrically SIMMONDS PRECISION PRODUCTS Inc 26 June 1973 [26 June 1972] 30307/73 Heading G1N Apparatus for measuring the torque transmitted by a shaft comprises a first toothed wheel 26 Fig. 4, fixed via a sleeve 25 to one end of the shaft 27 and a second toothed wheel 28 fixed directly to the shaft 27, each wheel coupling magnetically through normally stationary toothed wheels 30, 31 respectively with a permanent magnet and a pick-up coil (not shown) to produce two pulse trains whose phase difference is pro-  portional to twist and therefore torque. When the speed of the shaft is low and the pulse train voltage induced in the pick-up coils is below a predetermined threshold value, a motor 33 is energized to rotate the secondary toothed wheels 30, 31 at the same speed, to produce the two phase-displaced pulse trains. In one embodiment Fig. 6, the first and second toothed wheels 54, 57 are inter-digitated to produce a compound pulse train through a single pick-up toothed wheel 11. An additional toothed wheel may be fixed to the sleeve 25, and its pick-up voltage compared with that derived from wheels 26, 30 to obtain a reference pulse train compensated for shaft misalignment. The secondary toothed wheels 30, 31, 11 may alternatively be worm gear.

Patent GB-777044-A (GB)
Title: Process for the production of esters from olefins
IPC: C07C51/14
Filed: 1953-11-03
Abstract: Esters are produced by reacting an olefine having a boiling point above 320 DEG  C., or a hydrocarbon mixture containing one or more of such olefines, at 100-200 DEG  C. and 100-300 atmospheres in the presence of an oxo synthesis catalyst, e.g. a cobalt catalyst, with a gas containing carbon monoxide and hydrogen in which the CO : H2 ratio is greater than 2.  The preferred feedstocks are obtained by hydrogenation of carbon monoxide in the presence of a fixed bed or suspension of a precipitated iron catalyst containing 30-50 per cent of its iron content as metallic iron, which yields more than 20-40 per cent of normally solid hydrocarbons.  The oxonation process yields mainly esters, but acids and alcohols are also obtained.  The acids may be removed by a caustic wash or they may be esterified with alcohols, preferably with the alcohols obtained in the process.  In examples: (1) water gas is contacted with a catalyst comprising Fe, Cu, K2O and SiO2 (for preparation of catalyst see Group III) at 10 atmospheres, the load of 100 volumes of gas/v/hr. with a recycle ratio of 2.5 : 1 at 213 DEG  C. giving a product of saturated and unsaturated hydrocarbons boiling above 320 DEG  C.; this product is treated in an autoclave in the presence of a cobalt catalyst with mixture of carbon monoxide and hydrogen (CO : H2 ratio greater than 2) at 125 DEG  C. and 100 atmospheres giving an ester-containing product; (2) hydrocarbons are synthesized from water gas using a reduced catalyst comprising iron, copper, alkali and barium oxide at 211 DEG  C. and 15 atmospheres with a load of 150 v/v/hr., and the resulting product is oxonated as in (1); (3) a mixture of carbon monoxide and hydrogen with a CO : H ratio of 1 : 1.7 is contacted with a Fe, Cu, K2O and SiO2 catalyst at 225 DEG  C., 30 atmospheres and a gas load of 500 v/v/hr. giving saturated and unsaturated hydrocarbons; this product is oxonated as in (1) and the ester product is dissolved in a boiling C8 hydrocarbon fraction with addition of p-toluene sulphonic acid to increase the ester content.

Title: Arrangement for the broad band compensation of characteristic errors occurring in two-terminal and four-terminal comparators in the vhf and uhf ranges
Inventor: BUHN UWE
IPC: H01P5/02
Filed: 1966-07-07
Abstract: 1,132,269. Impedance measurement. FUNKWERK DRESDEN, VEB. July 7, 1966, No.30635/66. Heading G1U. [Also in Division H1] In two and four terminal rotating loop comparators of the type where three coaxial lines meet at a point and have their other ends terminated by a standard reactance, a standard resistance and an unknown complex impedance respectively, while voltages are induced in the lines by coupling loops and slots in the lines, the degrees of coupling being adjusted to give a null at the point where the lines meet, a systematic error arises due to the finite distance between the input coupling points and the junction point. This is compensated for, according to the invention, by altering the characteristic impedance Z L  of each line to a value Z LO  for the distance 1 1  between the coupling and junction points 2, 5 and for a distance 1 2  in the direction between the coupline point and the terminating impedance Y x . The relationship between the various parometers, which also include the remaining distance 1 3  to the terminating impedance Y X  from the coupling point and the wavelength of the energizing signal #, for each branch are given in the Specification. The characteristic line impedance changes may be produced by altering the diameter of the inner or outer coaxial conductors, or introducing a dielectric into the lines.

Title: Improvements in or relating to the treatment of milk and milk preparations
IPC: A23C9/152
Filed: 1934-10-31
Abstract: The digestibility of milk or milk preparations is improved by adding thereto an alkali-metal or ammonium metaphosphate having the property of reducing the concentration of calcium ions in the milk or milk preparation or liquids containing them whilst retaining the calcium in a water-soluble form, an effective amount of the metaphosphate being maintained in the milk &c. without material conversion to orthophosphate.  Preferably sodium hexametaphosphate is used.  The metaphosphate may be added in amount sufficient to combine substantially wholly with the calcium ions present to form a soluble but slightly ionized complex. Where it is desired to increase the calcium content of the milk, &c. a soluble calcium-alkali metal metaphosphate may be added, e.g. such as is produced by adding a calcium salt to a sodium metaphosphate solution, or there may be added directly calcium salt and an amount of sodium metaphosphate calculated to take care of the additional calcium.  The process may be applied to raw or pasteurized milk, to evaporated or powdered or other concentrated milk or to milk preparations, such as infants' food, for use by persons having delicate digestive systems.
