Title: Methods and means for reproducing optical images at a distance
IPC: H04N3/12
Filed: 1929-02-27
Abstract: 306,962. Postal Telegraph-Cable Co., (Assignees of Phinney, E. D.). Feb. 29, 1928, [Convention date]. Television.-In a television receiver means are provided for storing the impulses received successively, and for using the stored impulses simultaneously to reproduce the image as a whole, for example by energizing the multiple electrodes of a large discharge lamp. The lamp 10, Fig. 2, has strip electrodes 11, 12, &c., all joined together and to the common terminals of two banks of condensers C<1> and C<2>, and individual electrodes 13, 14, 15, &c. connected to the centre contacts of a multiple two-way switch SW<1>, the other two contacts of which are connected to individual condensers in banks C<1> and C<2> respectively, and to the contacts of two halves of a multiple rotary switch R. Switches SC<1> and SC<2> can short-circuit simultaneously all the condensers in banks C<1> and C<2> respectively. The signal impulses after amplification are applied between the wiping contact 36 of the rotary switch R and the lead common to all the condensers and lamp strips. The discharge of the condensers into the lamp is limited by electrical means 17 in the common lead. The shaft 35 rotates at half the speed of a scanning disc of known construction at the transmitter and by means of cams 34, 39 and 43 actuates switches SW<1>, SC<1> and SC<2> at the appropriate instant. The operation of the receiver is as follows. Assuming that the brush 36 is in the full-line position, Fig. 2, as soon as it advances to the dotted line position the cam 43 momentarily short-circuits all the condensers in the bank C<2>, the switch SC<2> being released a fraction of a second later. The condensers of bank C<2> are then charged successively by the signal impulses by way of the rotating brush 36, and the whole series of impulses due to one scanning of the picture is stored on the condenser bank C<2>, the brush 36 having now rotated through 180‹. Cam 39 now short-circuits bank C<1> momentarily and cam 34 discharges bank C<2> into the appropriate electrodes of the lamp. While this discharge is proceeding bank C<1> is being charged by the signal impulses ready for discharge when the rotary switch has completed one complete revolution. In this way while one picture is being shown by the lamp 10, another is being stored to be released simultaneously when the former. is beginning to die away. In other modifications of the same system, the condensers may be replaced by mechanical storage devices, the discharge tube 10 may be replaced by a plurality of small tubes, or other visual reproducing means, while the provision of switches SC<1> and SC<2>, and electric controlling elements 17 is optional.

Patent GB-471313-A (GB)
Title: Improvements in and relating to the manufacture of fancy yarns
IPC: D01D5/14
Filed: 1937-03-04
Abstract: <PICT:0471313/IV/1> Threads showing fancy effects due to differential shrinking of component yarns or threads are obtained by doubling finished textile yarns or threads of any origin with artificial silk filaments freshly produced from cuprammonium-cellulose solutions by a stretch spinning process, as they are leaving or shortly after they have left the spinning funnel and while they are still in the alkaline state before being acidified.  The doubled yarn is then acidified, further twisted if desired, washed, and subjected to finishing treatments.  Finished yarns or threads of cotton, linen, jute, wool, silk, artificial silk including viscose, cuprammonium, and cellulose acetate yarns, or other artificial yarns such as cellulose wool yarns may be doubled with the freshly produced artificial filaments.  As shown, filaments 2 spun from cuprammonium cellulose solution leave the lower end of the funnel 3, pass through vessel 5 and are there associated with a finished textile thread 4. The combined thread 9 passes round roller 10 and wooden roller 11 where it is treated with dilute sulphuric acid and freed from copper. It is then led into a spinning pot 12 where it is twisted and wound. The speeds of rollers 10, 11 may be adjusted as desired, but preferably roller 11 is driven at a slower feeding speed than roller 10 in order to facilitate shrinkage of the artificial silk filaments with consequent formation of loops in the yarn of different kind. Instead of a centrifuge, rollers, spools or reels may be used for winding up the doubled yarn.

Title: Improvements in and relating to the manufacture of xanthopterin and related compounds
IPC: C07D475/04
Filed: 1944-04-06
Abstract: Xanthopterin is produced by heating to about 110 DEG  C., preferably in a closed vessel under slight vacuum, 2.4.5-triamino-6-hydroxypyrimidine with dibromoacetic acid or with monochloracetic acid, and effecting ring-closure of the resultant halogenated products by warming with an aqueous alkali. Dihydroxanthopterin is the end-product when monochloroacetic acid is employed, and this is subsequently oxidized catalytically to xanthopterin.  To effect ring-closure, aqueous sodium bicarbonate is preferred, but aqueous alkalis such as sodium carbonate, sodium acetate or disodium phosphate may be employed, resulting in lower yields.  In examples (1) 5-dibromoacetamino-2.4-diamino-6-hydroxypyrimidine monohydrate is heated with aqueous sodium bicarbonate at 50 DEG  C. for 39 hours, and xanthopterin is precipitated on acidification with acetic acid (2) 5 - chloroacetamino - 2.4 - diamino - 6 - hydroxypyrimidine and sodium bicarbonate are together dissolved in boiling water and the solution is heated on a boiling water-bath, prior to acidification with N-acetic acid to precipitate dihydroxanthopterin which is converted into xanthopterin by shaking its solution in 3N-sodium hydroxide with oxygen in the presence of platinum black.  5 - Dibromoacetamino - 2.4 - diamino - 6 - hydroxypyrimidine is prepared by heating 2.4.5-triamino-6-hydroxypyrimidine with dibromoacetic acid in a closed vessel under slight vacuum.  5 - Chloroacetamino - 2.4 - diamino - 6 - hydroxy - pyrimidine is prepared by heating in a closed vessel under slight vacuum a triturated mixture of 2.4.5 - triamino - 6 - hydroxypyrimidine and monochloroacetic acid.

Title: Improvements in hydraulic control apparatus more especially for the control of electric circuit-breakers
IPC: F15B11/08
Filed: 1957-03-01
Abstract: 823,444. Hydraulic actuation of switches. GRATZMULLER, J. L. March 1, 1957 [March 2, 1956], No. 6929/57. Class 38 (5). [Also in Group XXIX] In an hydraulic control system for a circuitbreaker having a holding circuit as described in Specification 780,763, the holding circuit is connected to the pressure source by a duct and a non-return valve allowing liquid to escape to the pressure source thus relieving any excess pressure developed in the holding circuit. Fig. 2 shows an hydraulic system with the various ducts formed in, and the pilot valves 18, 24 and the exhaust reservoir 5 mounted on, the head 35 of the hydraulic accumulator 1 forming the source of hydraulic pressure. When the pilot valve 18 is opened, pressure liquid passes from the accumulator 1 via ducts 17, 19, 19a, to depress the auxiliary jack 15 which opens the selector valve 12 and so allows pressure liquid from the accumulator 1 to pass to the main circuit - breaker - operating jack (not shown) through the duct 8. Upon release of the pilot valve 18 pressure is maintained above the auxiliary jack by the holding circuit 20, 21, 22, 19a. Excess pressure is relieved from the holding circuit via the duct 27 and the non-return valve 28. The circuit-breaker is opened by opening the valve 24 thus venting the holding circuit to the exhaust reservoir 5 and allowing the valve 12 to close. Pressure liquid in the main circuitbreaker-operating jack passes to the exhaust reservoir through ports 4. The system also in cludes a quick evacuating device 31 as described in Specification 755,096 and a self-evacuating device as described in Specification 801,346, [Group XXIX]. Reference has been directed by the Comptroller to Specification 780,763.
