Abstract: 832,397. Paper-insulated cables. BRITISH INSULATED CALLENDER'S CABLES Ltd. July 4, 1958 [July 5, 1957], No. 21375/57. Class 36. In the manufacture of a paper-insulatert cable, the paper is first dried, by heating it and then cooling it to room temperature in an atmosphere of low relative humidity such that the moisture content of the dried paper is less than the equilibrium value at that humidity, and is then maintained in an atmosphere of low relative humidity while being cut into tapes and wound into pads and until and during the lapping of the tapes on the conductor, the relative humidity of the atmosphere during cutting and winding being at-least as low as that to which the paper is exposed until and during lapping. For example, the paper is dried by heating to 125‹ C. until its moisture content is less than 2 %, and then cooling in an atmosphere of 5% relative humidity or less. The paper is cut and wound into pads in an atmosphere of 5% relative humidity or less and the pads stored and lapped on to the conductor in a similar atmosphere. The cutting and winding of the tapes and the lapping of the tapes on to the conductor are effected in enclosures containing the appropriate atmosphere and the enclosures are contained in chambers having atmospheres of higher relative humidities (say 15%) than the enclosure atmospheres. The enclosures and the chambers are arranged so that there is an atmospheric flow from the enclosures to the chambers but not in the reverse direction.

Abstract: 893,990. Sight testing apparatus. GAMBS, P F. M. June 23, 1959 [Dec. 26, 1958], No 21514/59. Class 97(1). An ophthalmometer of the kind having two sighting marks which are projected on to the cornea of an eye under examination so as to form by reflection at the cornea images for observation through an eyepiece and having a beam splitting and beam combining system for duplicating the image of each sighting mark, is characterized in that the imagedoubling system includes two plane-parallel transparent plates at least one of which is rotatable relatively to the other for bringing the images into coincidence, and in that an afocal optical system is disposed in the light path between the cornea and the image-doubling system. As shown in Fig. 2, light from lamps is projected through sighting marks 18 and 19 on to the cornea 21 of an eye under test, and is reflected thereby through an afocal system 10, 20 on to a beam splitting and beam combining arrangement of prisms whereby two images of each sighting mark are formed for viewing in an eyepiece 9. Coincidence adjustment of these images is effected by rotation relatively to one another of plane-parallel transparent plates 6 and 11, such relative rotation being effected by movement of a rod 40, Fig. 3, having a cam section which engages a lever pivotally carrying one of the plates 11 and linked at 29, 28 to the other plate 6. Rod 40 is movable by rack and pinion, and has cam sections 35, 36 co-operating respectively with scales 37 of dioptres and 38 of radii of curvature. For operating with an aplanatic tonometer, reference marks are provided between cam sections 35, 36 to cooperate with a fixed scale.

Title: Improvements in and relating to the production of dietetic foods
IPC: A21D2/18
Filed: 1930-07-16
Abstract: In the preparation of foods, e.g. bread, farinaceous pastes, biscuits, &c., to render them suitable for persons suffering from diabetes &c., part or all of the water normally used is replaced by juice extracted from tubers, rhizomes, bulbs, roots, stalks or leaves of plants containing inulin and other valuable substances, e.g. inosite, after digestion thereof under heat.  Examples of the plants which may be used are given.  The roots &c. of Helyanthus Tuberosus, for example, may be cooked at 100 DEG  C. and the juice then extracted by pressure.  Besides inulin, inosite, and other alimentary substances, the juice is said to contain the active principles which prevent the formation of starch and its derivatives in the plants, and it may be filtered and preserved by refrigeration or by sterilizing and then keeping in closed receptacles until required for use.

Title: Transistorized d.c. amplifier
Inventor: FOSTER BASIL BERNARD
IPC: H03F1/56
Filed: 1965-05-21
Abstract: 1,049,369. Transistor amplifier circuits. STANDARD TELEPHONES & CABLES Ltd. May 21, 1965, No. 21601/65. Heading H3T. [Also in Division G1] In an amplifier for D.C. signals an A.C. signal e is applied via resistor 5 and capacitor 6 together with the D.C. input V to a transistor 3 and the A.C. signal is amplified and passed to a further amplifier 8, the output of which is rectified and supplied to the load in the emitter circuit of the transistor 3 so as to bias the transistor towards cut-off as the amplitude of the rectified signal increases. When a positive input is applied to 1 the output from rectifier 9 charges capacitor 10 so as to bias the transistor 3 to cut-off. As the D.C. input signal decreases the capacitor discharges through emitter resistor 4 and the current through, or the voltage across, this resistor 4 may be measured so as to determine the magnitude of the input V. Transistor 3 may be an NPN or PNP type or may be a composite transistor, e.g. Darlington circuit. The circuit produces a high input impedance and the output across resistor 4 may be further amplified. The A.C. signal may be in the form of a sine or pulse waveform. The amplifier 8 may be connected in series with the collector circuit of transistor 3, as shown, or alternatively may be connected in shunt.

Title: Liquid chromatography

Filed: 1971-04-27
Abstract: 1338257 Maintenance of axial equilibrium in liquid/solid chromatography UNILEVER Ltd and PYE UNICAM Ltd 27 April 1971 [5 May 1970] 21675/70 Heading B1X In a liquid/solid chromatographic separation a mobile phase comprising a non-polar carrier liquid, e.g. n-heptane, with a polar moderator, e.g. isopropyl alcohol is passed through a column 20, packed with, e.g. silicic acid. The temperature of the column is adjustable so that the partition coefficient of the moderator between the packing and liquid carrier can be changed. The composition of the mobile phase being fed to the column is likewise simultaneously changed to maintain axial equilibrium throughout the column. In one form this is achieved by passing the mobile phase through a packed pre column, e.g. 21, of greater capacity which is subject to the same temperature control. Alternatively the composition of the effluent mobile phase can be monitored so as to automatically control the mobile phase composition by admixture of the carrier and moderator. The admixture may alternatively be controlled at a pre-programmed rate in accordance with the temperature changes.

Abstract: 817,742. Aerials. MINISTER OF SUPPLY. Oct. 8, 1957 [July 13, 1956], No. 21694/56. Class 40 (7). The invention relates to an aircraft aerial system in which two spaced aerials are alternately connected to a receiving system and comprises a mounting for the two aerials which includes the switching means. The mounting is formed on a plate 1 having a flange 2 which can be riveted to the overlying edges of an aperture in the aircraft skin. The plate has two depressions 6 and 7 forming sub mountings for the aerial elements 8 and 9 which are spaced apart a distance between an eighth and a quarter of the working wavelength. The elements 8 and 9 may be fins arranged and mounted as described in Specification 712,265. A feed channel 12 extends from the feed point 13 between the elements 8 and 9 to the mid-point of transverse channel 14A, 14B which contains the respective aerial feed connections 17 and 18. The latter terminate at contacts 20 and 19 opposing one another across the channel 12 close to its end and are joined by the conductor 16 of a quarter wavelength transmission line formed in channel 15. The main feeder conductor 21 is led along the channel 12 and is capable of being flexed to make connection with either of the contacts 19, 20. Switching, which may be at the rate of 20 operations per second, is controlled by a solenoid 24 on the inner side of the mounting which moves the conductor 21 by means of linkage 25 and link 27. The channels are closed by a plate 28 apertured to allow the aerial elements to extend therethrough.

The cover is held open horizontally by stays 16 and serves as a shelf for tools &c. whilst replacing fuses with spares which may be clipped to it. A spring ball catch may retain the cover in the closed position.
