Abstract: 1,028,954. Semi-conductor pulse circuits. DANFOSS A/S Jan. 21, 1965 [Jan. 21, 1964], No. 2736/65. Heading H3T. [Also in Division G4] An analogue voltage U A  is applied to a solidstate threshold device 4 which is in turn connected to an integrating capacitor 5 and a differentiating capacitor 7. When the difference between U A  and U C  exceeds the threshold voltage, device 4 switches to a low resistance state, the direction of conduction through device 4 depending on the polarity of the difference between U A  and U C . As U A  rises by one increment, device 4 conducts and capacitor 5 is charged until the current through device 4 drops to a predetermined low level. A positive pulse is derived from capacitor 7 and passes through diode 9 for each positive increment of U A . A negative pulse is derived from capacitor 7 and passes through diode 12 for each negative increment of U A .

Title: Improved process for the vulcanization of rubber and the like
IPC: C08L7/00
Filed: 1923-01-30
Abstract: 200,788. Naugatuck Chemical Co., (Assignees of Cadwell, S. M.). July 13, 1922, [Convention date]. Vulcanizing-compositions.-India-rubber &c. in solid form or in solution is vulcanized with or without heat by mixing it with sulphur, zinc oxide, or certain other metallic compounds, carbon disulphide with or without addition of a substance, such as carbon tetrachloride, which reduces its inflammability, and a primary or secondary amine, which must be an aliphatic amine, e.g. benzylamine, if the inflammabilityreducing ingredient is absent. The zinc oxide may be replaced by compounds of zinc, mercury, lead, cadmium, copper, arsenic, or manganese. For reducing inflammability any inert liquid or gas, such as carbon dioxide, nitrogen, or products of combustion may be used. Carbon oxysulphide may be used instead of carbon disulphide. Suitable amines are methylamine, dimethylamine, diethylamine, benzylamine, dibenzylamine, piperidine, aniline, para-toluidine, triethyltrimethylenetriamine, and tribenzyltrimethylenetriamine. The carbon disulphide may either be added with the other ingredients during milling, or it may be applied subsequently by painting the articles with it or subjecting them to its vapour. In the case of cements the carbon disulphide and the amine may be added to separate portions of the composition which are mixed when required for use. The Specification contains several examples, of which the following are typical. (1) A sheet or article composed of 100 parts of rubber, 10 parts of zinc oxide, 3 parts of sulphur, and 2 parts of dibenzylamine is heated in a closed vulcanizer to 180-200‹ F. in an atmosphere of carbon tetrachloride vapour. A mixture of 1 volume of carbon disulphide and 2 volumes of carbon tetrachloride is introduced, and the temperature maintained for 2-3 hours. (2) 100 parts of rubber, 10 parts of zinc oxide, 3 parts of sulphur, 800 parts of benzol, 5 parts of benzylamine, and 5 parts of carbon disulphide are combined to form a cement which will vulcanize in 48 hours at ordinary temperature. Specification 200,789 is referred to.

Title: Heat treatment installation for bars or tubes juxtaposed in a layer
IPC: C21D1/63
Filed: 1963-01-28
Abstract: <PICT:1027646/C6-C7/1> Rods or tubes grouped into layers are heattreated in an apparatus characterized by a quenching tank having at its forward end a weir over which coolant overflows, the work entering the tank through the overflowing stream.  The latter is collected in a reception tank from where it is recirculated to the hardening tank; the coolant circulated may be duplicated so that alternative liquids may be employed.  The rate of cooling of the work may be controlled by adjusting the depth of coolant in the hardening tank or the size of the overflow orifice.  As shown in Fig. 7, bars 74 are caused by rolls 10 to traverse the coolant stream overflowing into reception tank 18 from hardening tank 3a through the orifice in wall 17, the orifice by means of hydraulically operated obturator 66. The hardening station is described and illustrated as one stage of a complete heating-hardening-tempering-cooling line.

Title: Method of making a pressure filled lamp
IPC: F21K5/08
Filed: 1955-02-07
Abstract: 785,689. Capping electric lamps. SYLVANIA ELECTRIC PRODUCTS, Inc. Feb. 7, 1955 [Feb. 10, 1954], No. 3615/55. Class 39(2) [Also in Group XXI] A metal cap 14 supporting the electrode assembly of an electric lamp, is sealed to the open end of a glass envelope which contains gas under pressure, e.g. up to about 2 atmospheres, by placing the cap in position on the open end of the envelope and introducing the assembly into a chamber wherein the atmosphere can be controlled and in which the envelope and its contents are surrounded by a metal hood in order to shield them from high-frequency oscillations applied to the metal cap to heat-seal it to the glass envelope. In the example a photographic flash lamp having a glass envelope 10 and a metal base cap 14 supporting leading-in wires or electrodes is filled with metal foil 29, and oxygen under pressure, and the envelope is sealed directly to the cap. The cap 14 may be of metal which can be sealed directly to glass, e.g. chrome steel alloys or the cap may be coated inside with glass frit. A depression 16 in the cap is also coated with glass frit and, after a lead 26 has been welded to the cap and a contact button 18 with attached lead 24 has been placed in the depression 16, the cap assembly is placed in a furnace. The temperature of the furnace is raised to form a glass enamel layer over the inner surface of the cap, while a glass seal between the button and the cap and around the wire extends through the cap. A filament 30 is then welded to the leads and coated with an ignition paste 28, which may have a zirconium powder base. Shredded foil is placed in the envelope 10, the cap assembly is mounted on a metal rod 40 and the reduced end 12 of the envelope is placed in the cap, a hood 42 being placed over the exposed glass. Attached to the hood is a spring 44 which bears against a bell jar 50 placed over the hood and clamped to an annular seat 54 by a screw-threaded member 56. A resilient ring 52 is interposed between the jar 50 and the seat 54. Thus the lamp assembly is held in a sealed chamber communicating through holes 62 in the rod 40 with a tube 64 leading to a cross-piece 71. After evacuating the chamber by means of a vacuum pump connected to one arm 72 of the cross-piece, oxygen under pressure is delivered to the chamber through arm 74. A third arm 76 of the cross-piece is connected to a gauge. When the required oxygen pressure e.g. 1.6 atmospheres, has been reached, a radio-frequency coil 70 surrounding the bell-jar is energized. The glass-enamel lining the cap is thus softened and after cooling is sealed to the envelope. The rod 40 is made of good heat-conducting material so that during the sealing process heat is rapidly carried away from the contact 18 to prevent cracking of the seal between the contact and the cap. The hood 42 also acts as a heat shield for the glass envelope. The outer surface of the envelope may be lacquer coated.
