Title: Improvements in electric switch fuses
IPC: H01H21/16
Filed: 1922-10-24
Abstract: 207,956. Railing, A. H., Garrard, C. C., and Searle, A. F. Oct. 24, 1922. Switches, quickbreak.-An enclosed electric switch - fuse has the fuses C carried at the front of a sliding insulating plate or carrier K which is mounted' on guide pins J and carries on its rear face contacts B adapted to co-operate with fixed contacts A. On rotation of a two-armed operating lever P secured to the spindle E, an arm E<1> secured thereon engages a shoulder F' of a cam piece F, loosely mounted on the spindle and by rotating the cam piece enables a roller N at its free end to press against a metal plate O fixed to the carrier which is thereby moved inwards against compression springs M to produce engagement of the fixed and moving contacts A, B. In the closed position (Fig. 1) the roller N is at or near the dead-centre position, the switch being held closed until the handle P is rotated in the opposite direction to engage the other shoulder F', thereby rotating the cam piece F and allowing the reaction of the spring M to produce a quick opening movement.

Title: Improvements in or relating to protective spark gaps
Inventor: TRAIN DAVID
IPC: H01T2/02
Filed: 1964-07-14
Abstract: 1,080,623. Protective spark gap arrangements. ENGLISH ELECTRIC CO. Ltd. July 12, 1965 [July 14, 1964], No. 28923/64. Heading H2H. A protective spark gap arrangement for a D.C. power line comprises a trigatron 11 having carbon main electrodes 15, 16 respectively connected to the line 13 and earth 14, which electrodes carry insulated trigger electrodes 19, 20 respectively connected to tappings 25, 26 on resistors 23, 24 in series with a spark gap 22 between the line and earth. In operation a predetermined surge voltage breaks down the gap 22 thereby causing each trigger electrode 19, 20 to spark over to its corresponding main electrode 15, 16 and so break down the gap 21 between these two electrodes to discharge the line voltage. The gap 22 is mounted in a sealed porcelain housing with or without the resistors 23, 24 one or other of which may be omitted in which case the trigger electrodes may be connected to tappings on the single resistor. One or other of the trigger electrodes may be omitted and the gap 22 may comprise multiple gaps in series. The sparking end of the trigger electrode may lie flush with the surface of the main electrode or be withdrawn within the body thereof. Each trigger electrode comprises a tungsten rod and the method of mounting this rod in the main electrode, Fig. 2 (not shown) comprises securing its lower end by a collet chuck 32 screwed into an insulating bushing 30 mounted in the electrode 16, and surrounding its upper (sparking) end by a ceramic sleeve 33. The electrodes 19, 20 are coaxial with the line joining the centres of the main electrodes 15, 16 which may be of any shape and disposition producing a uniform electric field in the gap 21, through which air may be blown to keep the electrodes free from dust.

Patent GB-1356102-A (GB)
Title: System for detecting malfunctioning of a digital transmission  channel
IPC: H04L1/00
Filed: 1970-06-16
Abstract: 1356102 Digital transmission; error detection POST-OFFICE 4 June 1971 [16 June 1970] 29032/70 Heading H4P A determined multi digit check signal not derived from information digits is dispersed among digits transmitted through a channel and extracted at a receiver for comparison against an image of the original. The information digits are divided into groups of known length and digits of the check signal inserted between each group. In a particular embodiment information digits are compressed in time with check signals inserted before transmission which are extracted on reception and the information signals expanded to the original form. In one embodiment information signals received on line 11 are diverted alternately in groups of nine into shift registers SR1, SR2. The check pattern is formed by a generator PT which is preferably of pseudo random type driven at one tenth the signal rate. Information signals plus check bits are read from registers SR2, SR1 alternately at 10/9 times signal rate for transmission through the channel. At the receiver Fig. 3 (not shown) shift registers (RR1, RR2) are also used alternately with the check bits diverted through gate (RG2) to a register (RPR) coupled to a comparator also receiving signals from a pattern generator (RPT). On detection of an error a signal is passed to a counting element (EC) which also includes an error rate device thus discriminating between an intermittent error and a more continuous one due to loss of alignment in the structure of the incoming bit stream. If the intermittent error rate is high enough but not high enough to be due to loss of alignment a switching means, not shown, may effect change to another channel or other action as may be determined. In an alternative arrangement Figs. 5 and 6 (not shown) an incoming bit stream is passed into a single shift register with a rapid dumping facility into a second shift register from which bits are transmitted. At the receiver a variable delay register (RDR) can provide increase or decrease of one bit every few groups in order to obtain synchronism.  The check pattern can alternatively be generated by performing a single logical operation on digits stored in two stages of a shift register to produce a third digit which is entered into an earlier stage: a converse operation on reception is performed.

Abstract: 168,800. Sullivan, P. Oct. 14, 1920. Winch-actuated lever load-handling machines and appliances.-Comprises means for loading vehicles. A load-carrying grid or solid platform 9 is pivoted centrally to links 4 having groundengaging ends 6. Links 2 are pivoted at one end on the vehicle axle and at the other end to the levers 4. A movement of the vehicle in the direction of the arrow causes the links 4 to rotate about the ends 6 as fulcrums. and thus move the platform upwards and inwards towards the vehicle. A winch 18 carrying a chain 13 passing over a guide roller 16 to the forward end of the platform may be used to assist and complete the movement by drawing the platform well over the vehicle body. A second rope or chain 22 may pass from the winch to the rear end of the platform or may pass to a load-enclosing means such as a net. The winch may be operated by hand or connected by chain gearing to the vehicle axle. In the latter case a clutch is fitted for rendering the drum inoperative at will. The rear end 27 of the platform is pointed so that it can be forced under a load when the vehicle is backed.

Filed: 1929-09-28
Abstract: 334,408. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 28, 1929. Fireproofing; proofing-compositions. - Combustible substances are fireproofed by impregnation or coating with solutions or suspensions of combustion retarding agents such as ammonium phosphate or sulphate, silicates, or zinc salts, and urea-formaldehyde condensation products. The latter substances adhere to the material and prevent crystallization. Other agents preventing crystallization such as glue or starch, may be added. In one example, wood is immersed in an aqueous 30 per cent solution of a condensation product obtained by condensing urea with aqueous formaldehyde in the presence of an acid agent, to which solution 20 per cent of its weight of diammonium phosphate has been added. The wood is left in the solution for two hours under a vacuum and for four hours at a pressure above atmospheric. After removing the surplus solution, the timber is dried. In a second example, textile fabric is dipped into an aqueous solution containing from 10 to 20 per cent of diammonium phosphate and from 1 to 2 per cent by weight of water soluble condensation product of urea and formaldehyde, with the optional addition of from 1 to 2 per cent of starch or glue. The fabric is then centrifuged and dried. In a third example, 20 parts by weight of dimethylolurea and 60 parts by weight of diammonium phosphate are dissolved in 100 parts of water, and the mixture is warmed to about 50‹ C., if desired, about 1 part of aqueous 10 per cent sulphuric acid being added. Timber is then immersed in the solution for about ¥ of an hour, preferably under vacuum. The vacuum is then released, and the timber removed and dried.
