Title: Improvements in or relating to cathode ray tube arrangements
IPC: H01J29/62
Filed: 1953-05-11
Abstract: 739,196. Cathode-ray tubes. TELEFUNKEN GES., [formerly TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE]. May 11, 1953 [May 9, 1952], No. 13012/53. Class 39 (1). In a cathode-ray tube comprising a cylindrical neck portion and a flared portion containing the fluorescent screen, and provided with an electromagnetic deflecting system and an electrostatic focusing system, the arrangement is such that the deflecting field penetrates into the focusing field to the following extent. The diverging portion of the electrostatic focusing system at the exit end of the system commences at such a distance a from the point at which the neck portion of the tube of internal diameter D is connected to the flared portion as to satisfy the inequality D/2 tan 6 < a <( D/tan 0, where #, the maximum angle of deflection, is greater than 30 degrees. Defocusing of the electron beam is thereby diminished, and the overall length of the tube is reduced. The electrostatic focusing system consists of an accelerating electrode 3 having a diaphragm 4 provided with a beam limiting aperture, a focusing electrode 5 and an anode 6 electrically connected to the accelerating electrode 3. In order to prevent any currents which may be set up on the electrodes from effecting a damping action on the deflecting field, the electrodes are preferably made of partially conducting material.

Title: Improvements relating to the production of chromic oxide
Inventor: CORBRIDGE DEREK EDGAR CHARLES
IPC: C01G37/02
Filed: 1963-04-02
Abstract: <PICT:1038773/C1/1> In a process for the production of Cr2O3, an aqueous solution of a thermally decomposable chromium compound is dispersed in a stream of hot combustion gas.  The heat required for the thermal decomposition is generated by combustion of liquid or gaseous fuel in the gas stream.  Alternatively, the gas stream may be incompletely burnt to obtain reducing conditions and further oxygen or air may be introduced after the Cr2O3 has been formed. Further combustion material may also be introduced into and burnt in the gas stream after formation of Cr2O3.  A minor proportion of a colour modifying compound may be included in the make solution of chromium compound.  The Cr2O3 formed may be recovered by scrubbing with H2O. Using the apparatus of Fig. 1, a 60% aqueous solution of chromic acid in vessel 1 and paraffin in vessel 2 were mixed in vessel 7, to obtain 80% by weight of chromic acid solution and 20% paraffin.  The mixture was injected into the spray head 10 at 0.2 litres per min. and 40 p.s.i., air being introduced via line 12.  The spray passes through the burner 16 where thermal decomposition occurs.  Reducing conditions were obtained by restricting the air supply by valve 13 so that the paraffin was not fully burnt.  The flame temperature was about 900 DEG  C.  The combustion was completed by air drawn in post burners 19 and 20.  The Cr2O3 which collected in vessel 23 was scrubbed with water introduced by spray nozzles 26 and withdrawn as an aqueous slurry at 27.  It was fine enough to use as a pigment without grinding.

Title: Improvements in or relating to lubricating grease compositions
IPC: C10M169/00
Filed: 1953-05-11
Abstract: A lubricating grease composition having structural stability at high temperatures is prepared by dispersing a calcium soap of a fatty acid containing more than 8 carbon atoms per molecule in a lubricating oil, dispersing in the mixture a barium strontium or magnesium soap of a substantially saturated fatty acid containing more than 8 carbon atoms per molecule so that the mol ratio of the calcium soap to the second soap is from 8:1 to 1:8, heating the resulting mixture to a temperature above about 350 DEG F, and cooling the resulting composition.  Suitable lubricating oils are mineral oils, esters (e.g. polymerized glycol esters, esters of dibasic acids with long chain alcohols, and complex esters made from dibasic acids, glycols and monohydric alcohols), glycol ethers, polymerized olefins, alkylated aromatics, polymerized silicones, formals and mercaptols. The soaps may be derived from such fatty acids as hydrogenated fish oil fatty acids, tallow fatty acids, fatty acids derived from the oxo process, hydroxy fatty acids, stearicacid and oleic acid.  In the examples, hydrogenated menhaden oil fatty acids are mixed with mineral oil and a slurry of calcium hydroxide in mineral oil then added.  The mixture is heated to 210 DEG F until formation of calcium soap by reaction between the calcium hydroxide and part of the fatty acids is complete.  Barium or strontium hydroxide octahydrate is then added and the temperature raised to 240-250 DEG F.  When dehydration is complete, further mineral oil is added, the composition is heated to 420 DEG F and then cooled.  For comparison purposes, the preparation of similar greases is described wherein the final temperature reached is only 300 DEG F and in some cases the barium or strontium hydroxide is replaced by magnesium hydroxide or omitted. The greases of the invention may be acid or alkaline and may be subjected to the action of the Morehouse mill.

Title: Improvements in or relating to methods of and means for wrapping objects having the shape of a solid of revolution
IPC: B65B11/04
Filed: 1937-05-07
Abstract: 475,775. Wrapping-machines. LAUENSTEIN & CO., GES. May 7, 1937, Nos. 13063 and 13064. Convention dates, Aug. 29, 1936 and April 22, 1937. [Class 94 (i)] Articles having the shape of a solid of revolution, for example, Easter eggs, small bottles and the like, are roughly wrapped in metal foil which is subsequently smoothed down upon the article. In order to effect the preliminary wrapping, the articles 3 are placed in shaped recesses 2 in a plate 1 and are raised by a plunger 5 to the position shown in broken lines in Fig. 3. The plunger 5 is shaped to support the article, in this case egg-shaped, over its lower surface, and to project at the ends so as to carry up a wrapper 7 placed on a die 6, to the upper position between grippers 8, 9, and to dispose it semicylindrically about the upper surface of the article and the ends of the die, with downwardly hanging ends. The plunger 5 falls and plates 10, 11 apply the ends to the underside of the article, the wrapper now having an approximately cylindrical formation. A member 12, Fig. 4, having end folders 13 rises and folds the lower part of the ends of the cylinder against the ends of the article, and a similar folder 14 descends upon the top, causing the article 3 and wrapper 7 to appear as shown in Fig. 6. Side folders 15, 16 complete the application of the wrapper, and the packet is now ready for the smoothing operation. The grippers 8, 9 release the packet on to a die 17, Fig. 7, which raises it through an aperture 18 in a plate 19. The plate 19 is stationary and is placed beneath a continuously rotating plate 21, having a sponge-rubber or like insert 24. The plate 19 is formed with a trough 23 conforming to the shape of the article, but having slight longitudinal protuberances so that the article is mainly supported at a, b, Fig. 10, during its rolling movement. The protuberances, however, are not sufficiently marked to prevent the smoothing action of the adjacent surfaces. The positions a, b are such as to maintain the proper position of the axis of the article, the peripheral speeds being in the same proportion as the distances from the axis 22. To this end, the distances p, q are proportional to the distances from the axis, and the positions a, b are determined by a radius r, projected from the point of intersection of the axis 22 and the plane M, so as to intersect the trough 23 at two points. In the form shown in Fig. 11, in which a bottle-shaped packet is being smoothed, the radius r intersects the surface of the trough at three points c, d, e. In a modification, a disc carrying radially disposed guides is interposed between the discs 19, 21 and is rotated at a speed less than that of the disc 21. The guides may carry rollers having an outline conforming to that of the article. When the trough 23 is straight, the distances of the protuberances from the plane M are equal.

Abstract: 473,702. Rug-making tools. COOKE, B. W. May 9, 1936, No. 13149. [Class 112] A needle for making rugs by tufting has a loop cutter comprising stationary and movable blades operated by a lever on the needle handle. The device consists of two slider handles A, B, the handle A carrying the needle N which penetrates the backing to carry wool or the like through, and the handle B carries a loop retainer C which holds the loop of wool while the needle is being retracted in readiness for the formation of the next loop. To produce a pile effect, the loops are cut by a scissors device S<1>, S<3> mounted on the retainer C, the blade S<3> being fixed and the blade S<1> being operated to cut the loop by the lever L<2> and link S<4>. The retainer C may itself form the fixed blade. The scissors may be operated automatically by replacing the lever L<2> by an inclined block T, Fig. 6, engaged by a spring tongue V when the handles A and B are slid on each other.
