Title: Improvements in and relating to protective devices for electric alternating current distribution systems
IPC: H02H7/22
Filed: 1920-07-06
Abstract: 169,818. Carney, H. A., Bowden, J. H., Thompson, H. F. J., and Johnson & Phillips, Ltd. July 6, 1920. Protective arrangements.-Relates to a leakageprotective system for multicore cables as described in Specification 4585/15 in which two conducting shields, one 4 insulated from and separating the individual cores and the other 5 insulated from and surrounding all the cores, are kept at potentials different from earth by connecting them to a transformer 19 through relays 14, 15 which operate the main circuit-breakers 6, 7 on fault, in conjunction with a relay 9 at the remote end connected across the sheaths. According to the invention, the action of the relay at the remote end is improved by the use of a transformer having a three-limbed core, the primary 21 being arranged preferably on the middle limb and the divided opposing parts 18, 23 of the secondary on the other limbs. When a fault develops, one part of the secondary is earthed and its flux diverted more or less through the secondary winding of the other limb, the voltage of which tends to rise rather than to fall, and so ensures sufficient current flowing through the remote relay to ensure its operation.

Abstract: 782,713. Cathode ray tubes. GENERAL ELECTRIC CO. June 30, 1955 [June 30, 1955], No. 18965/55. Class 39(1). An electron gun is mounted in the tube neck by three or more springs some of which are locked with cement and at least one of which is free of cement, the springs abutting the neck of the tube at circumferentially spaced points. The invention can be applied to one gun monochrome or colour receivers, or to a three gun colour receiver as particularly described. The tube cone 2 has an annular flange 4 which is utilized for securing the tube envelope to base plate 10 of mandrel 9, the envelope being placed over the mandrel 9 by inserting four bolts 5 into holes in 10 until nuts 6 abut against 10 and securing the assembly by nuts 19. A plug is then placed on top of mandrel port 11 and the envelope adjusted by lock nuts 7, 8 to centre aligning ports 13 in the neck, after which the plug which has a lining of dissimilar material from that of port 11, is easily removed. Next three or more leaf spring devices, each made up of two or more overlapping leaf springs 22, 23 are assembled and spot welded to ports 24. Ceramic cement which may be of sodium silicate with a silica filler is now inserted into the spaces between the springs 22, 23 of two of the three leaf spring devices 21, the other leaf spring device 22, 23 having no cement (if there are more than three leaf spring devices one or more may be left free of cement). Then the three guns 16-18 are placed on ports 13 by inserting the unitary assembly of three guns 16-18 and leaf spring devices 22-23 into the tube neck ; this causes springs 22, 23 to slide over one another until they are at the correct angle to abut the tube neck. The assembly is then left for the cement to harden ; the resulting assembly having two rigid spacers (in each of which 22, 23 are locked together by cement) and one resilient spacer 22, 23 with no cement.

The swollen collagen fibrous material applied to the textile screen may be covered by another textile screen before salting out. The web may be applied from both sides. The textile screen may be a thin fabric that is a woven or knitted fabric or tulle, or a non-woven fabric which can be stitched, impregnated or reinforced, and may be made from polyamide or polypropylene fibres alone or in admixture with viscose rayon fibres. The web may be made from polyacrylonitrile, polypropylene, polyamide, polyester, viscose rayon, cotton, wool, flax or mixtures thereof. In order to facilitate penetration, while the swollen collagen fibres material penetrates through the textile fibres, the backing is exposed to pressure effects of sieves with mesh aperture value of 9-400 per square centimetre, e.g. while the backing passes through a set of rollers provided on their surfaces with the sieves. After tanning the backing may be washed, dried, and impregnated with a polyurethane or latex or an artificial grain applied by direct sticking of a ready made grain side sheet. The swollen collagen fibrous material may be obtained from leather splits or machine glue stock.

Abstract: 1423197 Zero compensation for two path photometers LABTRONIC AG GES FUR KLINISCHE LABORTECHNIK 24 April 1973 [25 April 1972] 19411/73 Heading G1A A photometer for measuring the absorption of a sample by comparison with a reference beam is provided with a zero compensation circuit including an electronic switching arrangement controlling the respective gains of amplifiers in the sample and reference channels to equalize their outputs when a 'blank' sample is used, the arrangement being such that a coarse adjustment followed by a fine adjustment is performed. As shown, Fig. 1, the signals from a sample channel photo-cell 31 and a reference channel photo-cell 34 are passed through respective amplifiers 32, 35 to outputs 45 and 46 to which a ratio circuit is connected to evaluate the absorption of the sample. The gains of amplifiers 32 and 35 are adjustable by means of FETs positioned in feedback paths, the resistance of each FET, and hence the gain of the associated amplifier, being determined by a logic circuit 33 under control of a binary counter (not shown). Fine control of the gain of the reference channel is provided through a D:A converter 39 under control of a binary counter 38. The outputs at terminals 45 and 46 are monitored by a comparator 37. To effect zero setting a blank sample is inserted and key 36 closed. Logic circuit 33 then increases the gain of both channels in coarse steps until the output voltages are suitable for subsequent circuits and the output of the reference channel is slightly below that of the sample channel. The coarse adjustment is then stopped and the fine adjustment is started, a clock 41 feeding counter 38 to increase the reference channel output until it is identical to the sample channel output. The fine adjustment is then stopped and lamp 40 is illuminated to indicate that the zero setting operation is complete. The coarse and fine adjustment counts are stored to maintain the gains of the two channels constant during subsequent measurements.
