Title: Method of vacuum degasifying molten steel by circulation
IPC: C21C7/10
Filed: 1959-09-28
Abstract: 930,373. Degassing steel. YAWATA IRON & STEEL CO. Ltd. Sept. 28, 1959 [Oct. 3, 1958], No. 32936/59. Class 72. A method of vacuum degassing steel comprises raising the molten steel from a ladle into a vacuum vessel in which it is subjected to a rotary magnetic field to rotate the metal, the steel being raised through a central pipe dipping into the ladle and being returned to the ladle through a pipe at the side of the vessel. As shown, a vacuum vessel 6 has a central pipe 3 through which steel from a ladle 1 is raised into the vessel and a pipe 4 at the side of the vessel through which the degassed steel is returned to the ladle. A coil 8 surrounding the vessel sets up a rotary magnetic field which produces a rotary movement of the steel in the vessel and at the same time induces sufficient heat in the metal to prevent cooling thereof.

Title: Electrical circuit breaker and contacts therefor
IPC: H01H33/70
Filed: 1974-07-25
Abstract: 1445217 Gas-blast circuit breaker contacts SIEMENS AG 25 July 1974 [2 Aug 1973] 33010/74 Heading H1N A fixed, hollow contact for a gas-blast circuit breaker comprises a ring or tube 3 of conductive material, e.g. cold-hardened copper or a copper alloy, supporting a circular nozzle 7 of a material, such as graphite, having a conductivity less than that of the ring or tube but which increases when the material is subjected to pressure, the external diameter D1 being greater than that of the ring or tube D2 where the transition from one to the other takes place along the outer surface. The increase in diameter should be at least 0À2 mm., preferably 0À4 to 0À8 mm. Thus a moving contact, such as a tulip contact, engaging the outer surface, will exert increased contact pressure on the nozzle at the moment of transition and so lessen the likelihood of arcing at that junction due to a voltage jump during a contact separating operation. A circuit breaker may comprise a pair of such contacts co-operating with a moving bridging contact in a gas-blast breaker in a break chamber of porcelain filled with SF 6 .

Abstract: 1333035 Tris-(trimethylsiloxy)-phenylsilane BAYER AG 14 July 1972 [16 July 1971] 33098/72 Heading C3S Tris-(trimethylsiloxy)phenylsilane is prepared by hydrolysis of a mixture of trimethylmonochlorosilane and monophenyltrichlorosilane in a molar ratio of 3À3 : 1 to 4 : 1 by the gradual addition of water in excess and in the presence of 0À2 to 12À0 mols. of hexamethyldisiloxane per mol. of monophenyltrichlorosilane. The hexamethyldisiloxane may be previously stirred with 1 to 20% weight of an acid equilibration catalyst such as sulphuric acid or merely stirred with such catalyst at an elevated temperature below its boiling point. Alternatively the hexamethyldisiloxane may be produced in situ, e.g. by adding sulphuric acid to the reaction mixture to convert a suitable excess of the trimethylmonochlorosilane reactant. Preferably sulphuric acid is warmed to 50‹ C. with hexamethyldisiloxane for 30 minutes, phenyltrichorosilane is gradually added, followed by addition of trimethylchlorosilane at 30‹ C. and lastly stirring in of water at room temperature over a prolonged period of time.
Patent GB-445099-A (GB)
Title: Improvements in or relating to automatic or semi-automatic telephone systems
IPC: H04Q3/00
Filed: 1935-11-29
Abstract: 445,099. Automatic exchange systems. STANDARD TELEPHONES & GABLES, Ltd., 63, Aldwych, London.-(Assignees of McKim, J. B.) Nov. 29, 1935, No. 33179. Convention date, March 20. [Class 40 (iv)] An outgoing repeater includes a register switch 200 which receives the incoming impulse trains in an additive manner and a follow-up switch 250 which advances as the outgoing impulses are sent and determines the number of impulses in each train. Each time the register switch comes to rest at the end of a train a condenser is charged and thereby marks a stopping position for the follow-up switch. The outgoing impulses are generated by a condenser-timed relay 125. As shown, line relay 107 closes a series circuit for 114, 115, and these relays connect up 116. Relay 103, which is normally energized in series with 106, is short-circuited and 106 operates, connecting up 118, 124. Incoming impulses are repeated to magnet 207 of the register 200, and 114 falls back at the beginning of each train. Condensers are connected to the terminals of wipers 201, 202 over which they are successively discharged and to the succeeding terminals of wipers 203, 204. At the end of each train, the reoperation of 114 completes a charging circuit for the condenser connected to the terminal on which wiper 203 or 204 is standing. The condensers thus charged mark terminals of wipers 253, 254 of the follow-up switch 250. Relay 106 falls back at the first step of the register 200 and disconnects 118 which completes the forward loop and closes a circuit for relay 125. This relay is differentially wound and is controlled by a condenser 131 in such a way it operates and releases 20 times per second. Relay 133 pulls up at the first operation of 125 due to the removal of a short-circuit, and as the succeeding relapse, 124 is short-circuited. At the next operation of 125, the holding circuit of 133 is opened and 124 re-operates. Thus, relay 124 breaks the forward loop 10 times per second. Each operation and release of 133 sends an impulse to magnet 257 of the follow-up switch 250. When a marked terminal is reached, the charged condenser is connected over wiper 253 or 254 to the grid of a discharge tube 120, which thereby ionizes and operates relay 117. The circuit of 133 is thereby opened, and 106 energizes, disconnecting 125 and connecting up 118, 124, the latter maintaining the forward loop. Relay 118 opens the anode circuit of the tube 120, so that 117 falls back, initiating the slow release of 106, 118, after which the circuit of 125 is again closed to send the next train of impulses. After the last train has been sent, switches 200, 250 stand in corresponding positions and 106 remains held over wipers 205, 255 or 206, 256. Upon reply, relay 127 operates 'and connects up reversing relay 108. During release, relay 103 is brought into circuit and 106 falls back. If release takes place prematurely, with 115, 103 both back, magnet 257 operates in a self-interrupting circuit to advance the switch 250 to the position occupied by the register 200.

Abstract: 1,130,118. Bread flavour. BEATRICE FOODS CO. 21 July, 1967 [25 July, 1966], No. 33558/67. Heading A2B. [Also in Division C6] A synthetic bread flavour is prepared by growing a yeast of the genus Saccharomyces on a whey medium. The bread flavour may be prepared by growing the yeast Saccharomyces cerevisiae, preferably a mixture of the yeast with non-toxic bacteria of the coccus family (specifically, enterococcus of seriological group D, Streptococci of group N or Lactobacilli), on cottage cheese whey for 14 to 18 hours at 85-86F., concentrating the broth under vacuum and then spray drying the concentrate. Alternatively, the concentrate may be cooled to 110F., seeded with α-lactose, further cooled to 70 F. and then spray dried at 80F. The whey culture medium should have between 6% and 40% total solids and include diammonium phosphate in proportions ranging from 0.01 and 0.2 mol/litre. The bread flavour may be included in specified breads e.g. by addition of the simulated flavour to bread doughs in proportions ranging between 0.5% and 15% by weight of the flour, in rice stuffing and in dips made from cheese or sour cream. Certain of the examples are directed to the incorporation of the bread flavour into batter, muffin mixture and bread dough prior to baking or other cooking. When chemically leavened doughs are employed, bread flavour may be supplied entirely by the simulated bread flavour.

Title: Improvements in and relating to methods of bonding carbon and a metal
Inventor: ROBINSON JOHN SYDNEY
IPC: B23K35/32

Abstract: A metal body is joined to a carbon body by forming a metal carbide layer over the surface area of one of said bodies during a preliminary heat-treatment and joining the two bodies by a further heat-treatment to form a carbide bond between the second body and the carbide layer.  A conventional jointing method such as spot welding is used.  The carbide layer may be formed from a metallic layer on the carbon, preferably by using a mixed metallic powder of tungsten with nickel, iron or cobalt.  To avoid excessive combination of carbon and the metal surface, an intermediate coating of the metal by a metal less absorbent of carbon may be used e.g. steel may be coated with nickel or copper.  The powder may be used as it is or applied in a small quantity of bonding medium.
