Filed: 1972-06-26
Abstract: 1395635 Measuring capacitance WIGGINS TEAPE RESEARCH & DEVELOPMENT Ltd 25 June 1973 [26 June 1972] 29782/72 Heading G1U The capacitance of a capacitor 6, Fig.1, under test is measured by the following steps:- (a) first, a switch 2 is closed to charge the capacitor 6 to a reference potential V, (b) second, the switch 2 is opened and a switch 3 is closed so that the charge on the capacitor 6 flows into an integrator 4, and (c) third, the output voltage from the integrator, which voltage varies directly with the capacitance of the capacitor 6, is sampled, held, and displayed 5. A suitable control circuit Fig.4 (not shown) is described in which during the charging phase the charged state of the capacitor 6 is detected by monitoring the voltage across a resistor (14) in series with the switch 2, and during the discharge phase the discharged state of the capacitor 6 is detected by monitoring the voltage across a resistor (16) in series with the switch 3. The arrangement is said to be particularly useful when testing paper carrying a dielectric layer for electrostatic printing.

Abstract: 966,846. Coiling. TREFILERIES LEON BEKAERT. July 26, 1963, No. 29795/63. Headings B3E and B3V. A method of increasing the elastic elongation of a cable consists in first forming the cable into a helix by winding the cable round a core wire and then separating the cable from the core wire in such a manner that the cable retains its helical form. A cable composed of a number of strands twisted together is wound on a smooth wire core and is thus given a helical form. A spool 1 of such material is mounted in a twister a rotated about an axis x in a direction to tend to unwind cable 3 from the wire core 2. The cable 3 and core 2 are fed over a guide 4 up to a conical deflector 7 through which the core passes the cable 3 being deflected on to a spool 8 of a twister b rotating about an axis y in a direction opposite to that of the twister a. The core wire 2 is wound on a spool 9 of a twister c rotated at a speed slightly greater than that of the twister b, the spool 9 also being rotated slightly faster than the spool 8.

Title: Improved preparation of alkali cellulosates and cellulose ethers
IPC: C08B15/00
Filed: 1938-10-21
Abstract: 508,766. Cellulose derivatives. TENNANT, W. J. (Dow Chemical Co.) Oct. 21, 1938, No. 30547.. [Class 2 (ii)] Alkali cellulosate is obtained by causing anhydrous cellulose to react with an alkalimetal amide in a medium of liquid ammonia at a temperature below 25‹ C. and under the vapour pressure of liquid ammonia at the temperature employed, the reaction. being carried out in the absence of water. The product may be caused to react with an etheri. fying agent, e.g. an alkyl halide or sulphate so as to form a cellulose ether. Vacuum-dried anhydrous cellulose is suspended in liquid ammonia and treated with sodium amide, preferably in sufficient excess to axert a swelling action on the cellulose. According to the proportion of sodium amide present, mono-, di-, or tri-alkali cellulosate may be obtained. The temperature of treatment may be as low as -90‹ C., but is preferably in the region of - 20‹ C. An amide of sodium, potassium, or lithium, may be employed. It may be freshly prepared for the reaction by adding the alkali metal to liquid ammonia, preferably in presence of an iron or nickel salt as catalyst.: During " the subsequent etherification of the alkali cellulosate, there may be present an organic solvent, e.g. benzene, toluene or xylene. The reaction may be carried out at room tempereture or below and at a pressure equal to that of the vapour pressure of the reaction mixture. The cellulose ether obtained may be isolated by pouring the mixture into water, or by extracting it from the mixture by means of a solvent. In an example, metallic sodium, and ferric nitrate are added to liquid ammonia in a closed vessel and the mixture is stirred until the blue colour disappears. Finely divided anhydrous cellulose is added to the solution and the mixture is stirred for several hours, while ammonia is allowed to distil off slowly until .at the end of the reaction only enough liquid remains to wet the mass. The mixture is then cooled below - 33‹ C. and ethyl bromide and toluene are added. The mixture is allowed to stand for several hours, the temperature rising gradually to + 25‹ C. The mixture is then poured into hot water. The ethyl cellulose is separated from the water suspension by extraction with a solvent. Methyl, propyl, butyl, benzyl, or other simple or mixed ethers may be obtained in a similar manner. Alkyl chlorides, bromides, iodides, or sulphates may be used as etherifying agents.

Title: Improvements in electrical impedance bridges

Filed: 1960-09-05
Abstract: 1,004,313. Bridge circuits; detecting conductive and magnetic bodies. MEC-TEST Ltd, H. R. SHAYLOR, and P. D. WHITAKER. Sept. 5, 1961 [Sept. 5, 1960], No. 30578/60. Headings G1N and G1U. An impedance bridge has a first pair of resistive ratio arms having substantially the same resistances and a second pair of ratio arms containing sets of wound coils one set constituting a search coil and one a balance coil. The bridge is energized between the junction of the components of one pair of ratio arms and the junction between the components of the other pair, and a detector is connected across the junctions between the two pairs of ratio arms to indicate any out of balance of the bridge due to the presence of a metallic object in the field of the search coil. A coil connected in one of the second pair of ratio arms is physically associated with a coil in the other of the second pair of ratio arms, whereby changes of temperature which effect the search coil are compensated for because temperature changes cause equal resistance changes in both arms of the second pair of ratio arms. Each arm of the second pair of arms may include two equally matched windings 10 and 11, Fig. 1, connected in series opposition to form a non inductive portion and two windings 12 and 13 connected in series aiding to form an inductive portion, the arrangement being such that the windings 10 and 11 of the non-inductive portion of the first arm R3 are mounted on the same former as . the windings 12 and 13 forming the inductive portion of the second arm L4, and vice versa. The windings on one former constitute a search coil for the detection of metallic objects in medical work while the windings on the other former constitute a balance coil. Any change in resistance of the inductive portion of the search coil caused by temperature change will be compensated by the change of resistance also produced in the non- inductive portion of the opposite arm of the bridge. In further embodiments of the invention the search and balance coils may be wound on the same former but separated from one another to avoid mutual coupling, and the bridge may contain a capacitance as well as inductance in the search coil arm, (Fig. 2 not shown). Specification 575443, which describes a similar type of bridge used for detecting large masses of metal, is referred to.
