Title: Improvements in or relating to electric furnaces for the electro-thermal production of metallic magnesium
IPC: F27D11/02
Filed: 1942-07-30
Abstract: 558,972. Magnesium production in electric furnaces. SOC., ANON-POUR L'INDUSTRIE DE L'ALUMINIUM. July 30, 1942, No. 10686. Convention date, July 23, 1941. [Class 39 (iii)] In an electric furnace for the reduction of magnesium oxide or burnt dolomite with calcium carbide, ferro-silicon, silicon, aluminium, silicon carbide or calcium silicide which yield non-gaseous products, the heating resistance comprises a graphite tube 1 mounted between graphite cylinders 2, 4, the latter of which is connected by a cap 5 to a metal protecting tube 6. The spaces 8, 9 are exhausted of air to protect the resistance 1, and the cylinder 4 is mounted upon a flexible metallic conductor 3 connected to a supply terminal 18. The other terminal 18<SP>1</SP> is connected through the casing and tube 6 to the upper end of the resistance. The charge 12 is contained in a double walled iron tube 13 surrounded by heat insulation 16, and is under vacuum. Magnesium vapour is condensed in the hood 15. After the reaction, nitrogen or carbon monoxide is introduced, tube 13 is removed. and replaced by a fresh charge. A heating winding may be added between insulation 16 and tube 13. In a modification, Fig. 2 (not shown), the tube 13 is surrounded by an outer tube which separates it from the insulation space and the latter is open to space 8. An additional heating resistance may surround the above outer tube. A uniform heat distribution along the tube 1 may be obtained by tapering the tube at both ends. Specifications 412,417, [Group II], 450,064, 510,196, [Group II], and 526,669 are referred to.

Patent GB-288580-A (GB)
Title: Improvements in or relating to adding, sorting, statistical and like machines
Filed: 1928-04-11
Abstract: 288,580. Zeiss Ikon Akt.-Ges., and Goldberg, E., April 12, 1927, [Convention date]. Statistical apparatus.- In statistical apparatus the perforated cards or strips are read by rays of light in conjunction with selenium cells, bolometers, or thermopiles. The apparatus is illustrated for detecting a certain class of data from among various statistics. The statistics are photographed positively upon a film strip 1, Fig. 2, and a negative 2, Fig. 3, is made for the class of data to be detected. The negative 2 is made to register optically with the successive portions of the strip 1 and only when the letters of the negative correspond exactly with the letters of the positive is the light precluded entirely from passing through the combined positive and negative. This is used to operate a counter or recording device. Thus in the illustration only the first and sixth sections of the strip will be detected. Light passes from a source 7, Fig. 1, through a condenser 8, the strip 1 and a half-silvered mirror 3. The first part of the statistics, i.e. the lettering, passes on to the negative 2, condenser 9, and radiation-responsive element 6. When the stations correspond with the negative lettering the device 6 operates a relay 10 and magnet 11 to open a photographic shutter 5 so that the data from that section of the strip 1 are reflected by the mirror 3 on to the photographic plate 4. The latter is moved a step at each operation of the magnet 11 so that this plate will show finally the entire statistics corresponding with the classification of the negative 2. Instead of perforating the card the data may be printed thereon, the light passing through the unprinted portions; or printing may be in two colours, light passing therethrough to different degrees.

Title: Improvements in or relating to grabs
IPC: B66C3/08
Filed: 1938-04-09
Abstract: 508,896. Grab-buckets. PAGE, M. W. FLOOD-, and WESTWOOD & CO., Ltd., J. April 9, 1938, No. 10909. [Class 78 (iv)] To engage single - chain grabs with the usual suspension ring, disengage them therefrom and lower the empty grab with the jaws open, the supporting hook 6 is pivoted at 7 at one side of a member 19, the other side of which is pivoted at 4. During hoisting, the weight of the hook causes the member 19 to swing clockwise until stopped by the hook striking the pivot pin 3. In this position, the lifting chain passes freely through a central hole 11 in the member 19, and a stop on the chain passes to the upper side of this member during the closing of the jaws. When the-hook engages the Ting 16 and takes the weight of the grab, it rotates the member 19 counter-clockwise until the latter abuts against the pivot 3. In this position the off-set passage 12 is in line with the normal run of the chain. The stop on the chain cannot pass through this passage and is diverted to one side of it by cam members 13 when paying out the chain to open the jaws. When the stop passes below the member 19, gravity restores the chain to the vertical position so that when it is hauled in again, the stop is obstructed by the tapered recess at the lower end of the passage 12 and lifts the member 19 bodily until the hook is raised from the member 16 and falls outwards by gravity to the disengaged position. Lowering with the chain still in engagement with the member 19 then lowers the grab with the jaws open. When the chain is slackened after the grab rests on the heap of material, the hook is free to cause the member 19 to swing clockwise again ready for another cycle of operations.

Abstract: 809,120. Transmitting distant signals. STERN, W. L. March 18, 19.57, No. 11143/54. Class 40 (3). A substation or other remote station is provided with a television link with a main station by which the condition of the apparatus at the substation is indicated on a cathode-ray tube at the farther station, and control signals, derived from the optical signals on the tube, are again converted to optical signals fed back to the substation through a second television link where they are sensed by photo-cells as optical signals on the end of a second cathoderay tube and used to control the condition being indicated. The initial television signals may be derived from a liquid level gauge, instrument pointer, or a light source whose intensity varies with the signal supplied to it. To avoid operation of the system by light from extraneous sources, the light supplying the optical signals at both stations may be flickering at a frequency to which the means for deriving the control signal responds.
