Title: Self-damped laminar structures
IPC: F16F9/30
Filed: 1960-05-10
Abstract: 888,259. Vibration damping. BARRY CONTROLS Inc. May 10, 1960 [May 22, 1959], No. 16441/60. Class 108(3). [Also in Group XXII] A self-damped thin panel member comprises a pair of parallel laminates 48, 49, Fig. 11, secured together by the molecular adhesion of a damping medium 51 such as a silicon oil having a viscosity of at least 500,000 centistokes, one of the laminates 49 being substantially thinner than the other laminate 48 but having a: thickness at least sufficient to have plate-like load supporting characteristics when flexing so that maxium shear damping effects in the viscous medium are obtained. In examples the panels 48 may be of a thickness between <SP>1</SP>/ 32  and <SP>1</SP>/ 8  inch, the thinner laminate 49 being not less than ten thousandths of an inch and not greater than <SP>2</SP>/ 3  of the thickness of the laminate 48. The thickness of the damping medium is not greater than 25 thousandths of an inch and may be maintained by spacers such as projections 50 on the laminate 49. The thinner laminate may have a high modulus of elasticity and the use of a thin steel or beryllium laminate with a thicker laminate of aluminium is referred to. The laminates may be used for building up chassis assemblies on which delicate equipment may be mounted without intermediate isolation or damping provisions. The panels may also be attached to one or both sides of a metal honeycomb structure (Fig. 12, not shown) where higher structural strengths are required.

Title: Improvements in or relating to traffic signalling systems
IPC: B61L5/18
Filed: 1929-05-29
Abstract: 312,669. Telefonaktiebolaget L. M. Ericsson. May 30, 1928, [Convention date]. Road signals.-An electrically-controlled signalling system for the control of railroad and other traffic is arranged so that disconnection of all signalling devices included in the sign takes place as soon as any of the signalling devices fails to operate so that a deceptive signal can never be given. Lamps A, B, C are, as a rule, switched on indirectly by levers E<1>, F<1>, G<1>, through the auxiliary relay h which includes three normally closed series connected relay contacts a<1>, b<1>, c<1> on the corresponding relays a, b, c. The auxiliary relay circuit is also controlled by two contact arms F<2>, G<2> which are adapted to be shifted at the same time as the corresponding levers F<1>, G<1>. The circuit of the stop signalling lamp D is normally closed over a contact a<2> on the relay a. When the lever E<1> is shifted, the lamp A is switched on and the relay a is energized, thus disconnecting the lamp D at the contact a. If there is any interruption in the circuit of the lamp A the relay a is currentless and the lamp D remains in circuit. To switch on lamps A and B the lever F' is shifted thus shifting the lever F<2>, which on passing an intermediate position closes a circuit through the auxiliary relay h. The condition for closing the circuit of the auxiliary relay is that all the relays a, b, care currentless, for if any of them are alive the corresponding contact in the circuit of the auxiliary relay is broken. When the relay h is energized the contact h<2> is closed and the lamps A and B are supplied with current, the energizing of the relays a and b closing the contacts a<2>, b<2> and breaking the contacts a<1>, b<1>. By the making of the contact a<2> the lamp D is put out and by the breaking of the contacts a, b, the auxiliary relay h becomes currentless and the contact h<2> broken. If there is an interruption in the circuit of the lamp A, movement of the lever F<1> causes the disconnection of the circuits of the lamps A and B, and the lamp D remains in circuit. A similar operation takes place if there is an interruption in the circuit of the lamp B, either alone or in addition to an interruption in the circuit of the lamp A, so that a deceptive signal cannot be displayed. Movement of the lever G<1> lights the lamps A, B, C and, as in the preceding cases, if there are any interruptions in the circuits of the lamps A, B, C all the circuits are disconnected on the operation of the lever G<1> and the stop signal D remains in circuit. The circuit described above can be modified so that the control of the relays a, b, and c is effected indirectly instead of directly by the auxiliary relay h. A modification is described in which the relays a, b and c are replaced by one relay common to all lamp circuits, the different levers E<1>, F<1>, G<1> being connected to different points of the relay winding. A further modification is described for use with alternating current.

Title: Improvements in and relating to methods of sealing metal to glass
IPC: H01J5/40
Filed: 1937-06-15
Abstract: 502,551. Sealing metal to glass by heat. BRITISH THOMSON-HOUSTON CO., Ltd. June 15, 1937, No. 16624. Void. Convention date, June 16, 1936. [Class 36] [Also in Group II] A method of uniting a metal member and a glass member having different coefficients of expansion comprises sealing the metal member directly to the glass member, heating the structure so formed to the annealing point of the glass, and then cooling the member having the higher coefficient of expansion more rapidly than the other member. If the coefficient of expansion of the metal is not too much higher than that of the glass, the cooling may be effected by merely allowing the sealed objects to cool in the open air at ordinary temperatures; alternatively, a portion of the metal may be immersed in a liquid. The example shows a base assembly for electric lamps and the like, of the kind described in Specification 4,71,301 comprising a comparatively thick dish-shaped body 10, preferably of a borosilicate glass, into which prongs 15 are sealed by means of cup-shaped thimbles or flares 16 attached thereto. The flares 16 may be made of an alloy such as that known as "Fernico " and may be formed with tapering edges. Sealing is effected by flames of reducing gas, such as hydrogen, accompanied by pressure , upon the upper ends of the prongs, after which the assembly may be placed in a furnace such as that shown for the subsequent re-heating and cooling. This furnace comprises a container 22 with a refractory lining 23 and containing an electric heating-coil 24. A well 25 attached to the bottom of the container has inlet and outlet pipes 27, 28 respectively for a cooling-liquid, preferably water. Heating is effected with the sealed assembly arranged at right-angles to the position shown, so that the bottoms of the prongs 15 rest on the bottom 26 of the furnace, the temperature attained being about 600 to 650‹ C. The assembly is then turned and the prongs 15 inserted through the tubes 29 into the circulating water 31. The metal is thus cooled rapidly, while the glass 10 is preferably cooled down slowly through the strain point. Specification 368,934, [Group XI], also is referred to.

Title: A method of preparing a combined nickel oxide-tungsten oxide catalyst
Inventor: MCKINLEY JOSEPH BURNS
IPC: B01J23/84
Filed: 1954-06-10
Abstract: A combined nickel oxide-tungsten oxide supported catalyst is prepared by forming an aqueous solution of ammonium meta-tungstate having a pH of between 2 and 5, mixing therewith a solution of a nickel salt while maintaining the pH in the same range, impregnating a porous carrier with the mixed solution, and drying and calcining.  The solution of ammonium meta-tungstate may be formed (a) by reacting a slurry of tungstic acid with about 97 per cent of the theoretical amount of ammonium hydroxide, heating for 2 hours on a steam bath, allowing to stand for 2-24 hours, and then filtering; or (b) by adding excess ammonia to a slurry of tungstic acid, roasting the precipitated ammonium para-tungstate, and dissolving the product in water.  The nickel salt used may be the nitrate, chloride, or acetate; if the solution is too acid, ammonia may be added. Impregnation may be carried out by evacuating the carrier and soaking in the mixed solution. Suitable carriers are activated alumina, silica gel, synthetic silica-alumina cracking catalysts, or acid-activated natural clays.  When using a finely-divided catalyst intended for fluidized operation, it is advantageous to impregnate before elutriation.  For hydrocracking hydrocarbons, the relative amounts of the tungsten and nickel solutions may be adjusted to give a final catalyst having an atomic ratio of Ni:W of 0.10:1 to 1.0:1.0. The oxide in the final catalyst may combine to form nickel tungstate.

Title: Improvements in and relating to methods of and apparatus for forming silica and for coating lamp bulbs
IPC: H01J9/20
Filed: 1949-06-28
Abstract: <PICT:0680217/III/1> Fine particles of silica for coating electric lamp bulbs are formed by burning finely divided particles of silicon in the flame of a stream of combustible fluid carrying in suspension the silicon particles and collecting the resultant silica on an adjacent surface.  The electric lamp bulbs are coated by carrying into the interior of the bulb a stream of combustible fluid carrying in suspension finely divided silicon particles, burning the fluid stream inside the bulb so depositing a layer of silicon on the inner surface of the bulb, applying heat to the exterior of the bulb and blowing a current of air into the bulb to dry the coating.  Referring to the drawing, container 13 is filled with finely divided silicon and a flow of combustible gas (e.g. natural gas) started through conduit 12 carrying the silicon through conduit 15 and through burner tube 11 surrounded by tube 7 through which comes an oxygenous gas (e.g. oxygen) from tube 10 to issue around the stream of combustible gas and silicon and to be ignited there so as to burn the silicon in the atmosphere of the gas and excess oxygen.  The bulb is then dried. Instead of the combustible gas a combustible fluid, e.g. liquid alcohol, may be used.
