Title: Electric gas density measuring device
IPC: G01N9/00
Filed: 1949-05-11
Abstract: 664,786. Electric indicating systems. BENDIX AVIATION CORPORATION. May 11, 1949. [July 2, 1948] No. 12614/49. Class 40 (i). [Also in Group XXXVI] A gas density sensitive altimeter cell (Fig. 1) comprises a bulb 11, vented to the atmosphere at 13 and sealed to a 7-pin base 12 whose pins 14 and 15 internally support two vertical standards 17 carrying a plurality of equally spaced ceramic discs 18, enclosed by a tubular shield 19 which is centred within the bulb by larger ceramic discs 22. Each disc 18 has four equally spaced radial slots 20 in alignment with those of adjacent discs, and a fine nickel filament 21 is threaded through alternate slots of successive discs and connected through the base pins 14, 15 in a Wheatstone bridge (Fig. 2) comprising fixed arms 26, 27 and a variable arm 28. The filament 21 is heated by the current through the bridge and reaches temperature equilibrium with the surrounding air. The variable arm 28 is adjusted at sea level so that the unbalance meter reads zero. The lower air density at increased altitudes causes the filament temperature to increase, and the degree of bridge unbalance then indicated by the meter is a measure of the altitude. The sectional shielding of the filament reduces convection currents and errors due to extraneous forces applied to the cell. Two, three or four arms of the bridge may comprise similar cells. The device is applicable to measure the density of gas in a line.

Title: Process for producing a lithographic printing plate
Inventor: BOTTHOF CHARLES LAURY
IPC: B41C1/10
Filed: 1953-05-06
Abstract: 727,102. Planographic printing surfaces. STANDARD RATE & DATA SERVICE, Inc. May 6, 1953, No. 12628/53. Class 100 (2). A process of producing a lithographic printing plate comprises the steps of forming a laminated plate of a lamina of metallic foil and a lamina of deformable backing material, graining the exposed surface of the foil lamina, impressing an inked relief surface into the grained surface to create an inked image area at a distance inwardly of the grained surface beyond the printing plane of the surface by the indentation of the foil lamina, and thereafter forcing the foil lamina at the image area outwardly to dispose the image area at a printing plane at the exposed surface of the foil lamina. The metallic lamina may consist of aluminium foil from one to four thousandths of an inch thick, and the backing may consist of strong paper or card stock. The graining may be accomplished by sand-blasting and the inlaid relief surface is impressed by means of an inked forme or by typing through an inker ribbon. The ink on the plate is allowed to set and the plate is then treated with a weak acid and gum arabic to make the non-image area more waterreceptive and ink repellant. The depressed image areas are then raised to a proper printing plane by swaging or by passing the plate between pressure rollers.

Title: Improvements in and relating to electric light buoys and the like
IPC: F21V19/04
Filed: 1945-05-19
Abstract: 592,111. Replacing defective lamps. LONDEX, Ltd., and BESSON, A. P. May 19, 1945, No. 12674. [Class 75 (iv)] An electric light buoy has means for automatically changing lamps in which the lamp holders 1 are assembled one on top of each other with their longitudinal axes parallel in magazine-like arrangement. The holders 1 may have contacts 7 to be engaged by spring contacts 8, and the holders may be mounted on a platform 2 engaged by screw-threaded spindles 3 adapted to be rotated through gearing by a motor 6 to raise the platform. A flasher relay 14 comprising relay contacts 15, 16 and a coil 17 energized for a predetermined period by a capacitor 18 may be included in the electric circuit. During the bright periods when the contacts 15, 16 are closed, current is supplied to the lamp, which may be a filament or discharge lamp, through terminal 11, contacts 16, the lamp, the energizing coil of a relay 13 and terminal 12, the motor 6 not operating since the contacts 13 are held open. During the dark periods when the contacts 15, 16 are open, the current passes through a coil 19 of high impedance, this current being insufficient to light the lamp, but sufficient to hold the contacts 13 open to prevent operation of the motor 6. When a lamp fails, the relay 13 is de-energized, and the motor circuit is closed so that the platform 2 is raised until a fresh lamp is brought into place, when the operation proceeds as before. Variable resistances 20, 21 may be included in the flasher relay circuit to adjust the flasher period, and a switch 22 may be provided to stop the motor from operating when the last lamp holder 1 has been ejected. The platform 2 may be permanently secured to the buoy while the lamp holders may be provided with straight, curved or circular guides secured to stationary points which serve as electric terminals. A visible or audible signal may be actuated when the last lamp holder reaches its lighting position, and a container 10 may be provided to collect the ejected lamp holders.

Title: Electron beam correction apparatus for a color picture tube
IPC: H01J29/70
Filed: 1969-03-11
Abstract: 1,254,064. Colour television tubes. SONY CORP. 11 March, 1969 [11 March, 1968 (2)], No. 12690/69. Heading H1D. A plural beam, single guncolour cathode-ray tube, of the type having a central and two side electron beams which lie in a common plane passing through the tube axis and in which the side electron beams converge with the central beam at a beam selection means in front of the screen, has provided, as part of the beam convergence system, magnetic field generating means arranged on opposite sides of the central beam; at a location where the side beams are spaced from the central beam, which are operative to produce oppositely directed magnetic fields which are generally perpendicular tothe common beam plane. The arrangement is such that it produces lesser flux density in the region of the central beam than in the region of at least one of the side beams to correct for misconvergence of the beams due to misalignment of, for example, the beam gun electrodes. The magnetic fields may be generated by permanent .magnets 22R, 22B, Fig. 3, which are held in plastics sleeves 34R, 34B that are adjustably housed in plastics casing 31. Alternatively, electromagnets 22<SP>1</SP>R, 22<SP>1</SP>B, Fig. 6, may be used, which, ifeach is energized from separate supplies 25R, 25B, may be permanently secured to a fixed non- magnetic holder, Fig. 7 (not shown), thus obviating the need for mechanical adjustment. The permanent magnets or electromagnets may, as shown, be convex towards each other to reduce any unwanted magnetic fields between the oppositely-polarized corresponding ends of the magnets. Alternatively, Fig. 9 (not shown), the magnets may be concave towards each other, following the profile of the tube neck and the unwanted fields reduced by providing weak. auxiliary permanent- or electromagnets between the adjacent oppositely-polarized ends of the main magnets. A dynamic convergence correction current, derived from the horizontal and vertical sweeps, maybe superimposed on the current through each electromagnet 22<SP>1</SP>R, 22<SP>1</SP>B. As shown in Fig. 1, the three beams are derived from the single cathode of a single electrongun which. incorporates a main lens system L at the centre of which is a beam convergence point. The resultant divergent beams then pass through a beam convergencedeflecting means F, a deflection yoke 20 and a beam selection grill Gp before reaching the screen. Preferably, the magnetic field generating means 22R, 22B are disposed between the convergence deflecting means and the deflection yoke.

Abstract: A lubricating grease, having anti-corrosive properties and good water-resistance, comprises a lubricating oil thickened to a grease consistency by means of an inorganic gelling agent, and a minor proportion of a halogen-containing aliphatic epoxy-compound.  The lubricating oil may be a mineral oil or a synthetic oil or a blend of these two.  Synthetic oils mentioned are polymerized olefins, aliphatic esters of dicarboxylic esters (e.g. di-(2-ethylhexyl) sebacate), organic phosphates (e.g. tricresyl or trioctyl phosphate), polyoxyalkylene compounds (e.g. propylene oxide polymers, copolymers of propylene and ethylene oxides, trimethylene glycol polymers and esters and ethers of such polymers), and halogenated hydrocarbons (e.g. fluorocarbons and chlorinated diphenyl).  Fatty oils or fatty acids, such as oleic acid, may be blended with the lubricating oil. Suitable gelling agents are colloidal inorganic oxides, hydroxides, sulphides, sulphates, silicates and carbonates, such as silica, alumina, magnesia, calcium oxide, copper sulphide, calcium sulphate and mixtures thereof, particularly mixtures of silica with magnesia, as well as synthetic zeolites and natural clays, such as hectorite and bentonite.  The inorganic gelling agent may be employed in aerogel form.  A list of suitable mono-epoxy-mono-halo-alkanes is given.  The lubricating grease may contain additional ingredients such as other anti-corrosion agents (e.g. aliphatic polycarboxylic acids containing one or more alkyl or alkenyl groups with at least 3 carbon atoms, and the corresponding thio acids as well as the amides, anhydrides and esters of these acids), anti-oxidants (e.g. 2, 6-di-tert-butyl-4-methyl phenol or phenyl- -naphthylamine), extreme pressure agents (e.g. sulphur, lead naphthenate and sulphurized and/or chlorinated fats or fatty oils), and tackiness agents (e.g. rubber or polyisobutylene).  In the examples, lubricating greases consist of mineral lubricating oil, colloidal silica (prepared by burning in air hydrogen saturated with silicon tetrachloride), and epichlorohydrin, with or without a succinic acid substituted by a C18 alkenyl group.

Title: Improvements in and relating to a method of bonding sheets of dissimilar metals
IPC: B23K20/04
Filed: 1929-04-26
Abstract: 331,028. Palm, J. V. O. April 26, 1929. Plates; bearings; compound forms.-Sheets of dissimilar metals for forming bearings &c. are united by forming teeth on one surface of the backing strip of hard metal, compressing the tips of the teeth to produce overhanging edges and rolling a superposed strip of softer metal into the gaps between the teeth. A strip 4 of cold rolled steel is first toothed on one surface by knurling, indenting, &c. by rolls 1, 3 and is then passed between a second pair of rolls to form the recesses with overhanging edges 9. These operations also harden and temper the strip. A strip of babbit metal 10, which may be hardened by rolling, is then placed - on the indented surface of the steel strip and rolled so as to force the metal thereof into the recesses. The strip is then cut into blanks, which may be bent as shown in Fig. 8 to form bearings. The stel strip may be approximately 1-16th inch thick and the babbit strip 0.03 inch thick rolled down to a thickness of about 0.015 inch at the unrecessed portions and 0.025 inch through the portions extending into the recesses.

Title: Compressed air drive for electric switches
IPC: H01H33/32
Filed: 1930-04-28
Abstract: 352,593. Actuation of switches. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, and POST, 0. T., 15, Amselgrund, Hermsdorf, both in Berlin. April 28 1930, No. 13022. [Class 38 (v).] Pneumatic actuation.-A switch spindle 14 is rotated by means of an arm 13 and a piston 10. The admission of air to the piston 10 is controlled by valve gear so that a short period of depression of the operating-rod suffices for a complete operation of the switch. When the operating rod 3 is depressed, a valve 4 is opened admitting air from the chamber 7 so as to force downwards a piston 5 carrying a valve 15. This admits air from the chamber 7 to the working piston 10 to operate the switch. The piston 5 returns due to the action of the air pressure on the valve 15, but is retarded as the air can only escape through an adjustable needle valve 20. When the piston 5 is in the upper position a piston 9 uncovers a port 22 thus connecting the upper side of the piston 10 with the atmosphere. This allows of a ready return movement of the piston 10 due to a similar valve gear not shown, supplying air to the underside of the piston. The operating rod 3 may be manually or electromagnetically actuated.
