Abstract: 1,155,112. Vibrio fetus vaccines. COLORADO STATE UNIVERSITY RESEARCH FOUNDATION. 18 Oct., 1966 [20 Aug., 1966], No. 37403/66. Heading A5B. A vaccine for parenteral administration to female cattle to prevent infections bovine vibriosis comprises Vibrio fetus the virulency of which has been enhanced by serial passage in susceptible animals; i.e. animals which can be infected with V. fetus but which show sufficient natural defence to eliminate the weaker organisms and thus enhance the virulence of the culture. The Vibrio fetus organisms used may be of bovine or ovine origin and the preferred susceptible animals are heifers. Serial passage is effected by depositing a natural strain of the organism in the uterine cavity by intracervical introduction, and then isolating organisms from the cervical mucus of the thus infected animal. The initial strain may be obtained from a near full-term aborted fetus. The passaged organism is preferably then propagated on artificial medium under an aerobic conditions, but may be used as a vaccine directly. The artificially propagated organisms may be used as a live vaccine, or suitably killed and, if required, mixed with a vaccine adjuvant. The organisms may be killed with formalin or phenol, or by heating or repeatedly freezing and thawing. Suitable vaccine adjuvants are sodium alginate or a mineral oil-lanolin mixture, an aqueous suspension of the dead organisms being emulsified with the adjuvant to form the vaccine. The vaccine is preferably administered by subcutaneous injection.

Title: Improvements in or relating to the cementation of metals and metal alloys with beryllium
IPC: C23C10/30
Filed: 1938-12-23
Abstract: 523,071. Coating metals. DEUTSCHE GOLDUND SILBER - SCHEIDEANSTALT VORM. ROESSLER. Dec. 23; 1938, No. 37480. Convention date, Jan. 3. [Class 82 (ii)] [Also in Group XXXVI] In a process for the cementation of metals such as iron and steel or of metal alloys, a thin layer of beryllium is applied, without the addition of a protective substance such as varnish, to the metal surface which may have been roughened up, and is caused to diffuse practically completely into the metal &c. by heating at a temperature between 800‹C. and 1,100‹C. preferably in vacuo or in an atmosphere of inert gas or in fused salt baths. The thin coating of beryllium may be produced electrolytically, by powdering on or pressing into a roughened surface or by applying a thin coating of beryllium compounds and a reducing agent and heating, by vapourizing volatile organic compounds of beryllium, e.g., beryllium dimethyl or diphenyl on to the surface to be treated and then causing them to liberate metallic beryllium. The reducing agents used with the beryllium compound may be metals which form alloys with beryllium, said metal such as sodium, magnesium, aluminium or calcium being coated electrolytically on the surface and the beryllium compound with, if desired, alkali chloride added. Alternatively the surface may be coated with the reducing agent and then treated with beryllium compounds in vapour form. the beryllium set free being then caused to diffuse into the surface by increase of temperature. Other metals such as cobalt, nickel, copper and silver may be introduced with the beryllium into the surface by applying electrolytically a coating of these metals, then a reducing agent, such as magnesium and calcium and finally a coating of a beryllium compound. Other reducing agents such as carbon, carbides or hydrides of the alkaline or alkaline earth metals may be used or other cementation agents, such as carbon and silicon used with the beryllium and caused to diffuse into the metal surface. In a modification after the first layer of beryllium has been diffused into the surface of the metal, the latter may be coated with a further layer and heated as described and this process may be repeated. Also a metallic object such'as a plate may be coated with beryllium or its compounds, covered by an object of the same shape the two objects pressed together and then heated.

Title: Method of manufacturing aluminum coated steel strip
IPC: B22F7/04
Filed: 1971-08-12
Abstract: 1368332 Making composite strip; rolling NIPPON KOKAN KK 12 Aug 1971 37851/71 Headings B3A and B3M [Also in Division C7] An aluminium coated steel strip is made by applying an aluminium slurry to both faces of a steel strip, rolling the strip to compact the aluminium powder carried in the slurry, and heat treating the strip at 450-700‹ C. for 1 to 5 seconds. The heat treatment can be carried out using a combination high-frequency induction furnace and a radiation tube furnace, or using a bath of molten metal (e.g. lead). Lengths of strip from coils 1, Fig. 1, are welded end to end to form a continuous strip which is then degreased, washed, pickled, washed and scrubbed at 9. The strip is dried at 10 and coated with slurry at 12, the slurry comprising aluminium powder and water together with a stabilizing agent and a corrosion inhibitor. After passing through a rapid drying furnace, 13, the strip is rolled at 14 and heat-treated at 15 and 16. A water quenching tank 17, drier 18, chromate coating tank 19, drier 20, and shear 24 follow the heat treatment apparatus, the strip finally being coiled at 25. In an example, slurry containing aluminium powder of 15n average particle size, was coated on steel strip by a reverse roll coater. The strip was rolled so as to give a 5% reduction, was heated for 3 seconds at 600‹ C. in a lead bath, and was oil quenched. A high-frequency induction furnace is shown in Fig. 4, the furnace having individually controllable inductance coils 43a, and 43c, a hot air entry 42, and exhausts 46a, 46b and 46c. Windows 47a, 47b and 47c enable the condition of the strip 40 within the furnace to be monitored. Internally cooled rolls 51 and 52, Fig. 6, are provided in the rolling mill, each roll having an apertured pipe 55 extending axially through a central bore. Cooling water is fed through the tube from an inlet 64, and after passing back along the bore, passes through an outlet 65.

A contact-free switching circuit 2, for controlling operation of a D.C. traction-motor fieldcontactor 3 in response to the terminal voltage V 1  and current I 1  delivered by a diesel-electric or gas-turbine driven generator 15 on a locomotive, is switchable between two states to energize and de-energize the contactor 3, respectively, and the controlling input signal for circuit 2 is from a circuit 1 operatively controlled by the outputs of magnetic amplifiers 9, 10, which electrically isolate the circuit 1 from the generator 15 and have their outputs dependent upon functions of generator current I 1  and terminal voltage V 1 , respectively. Switching circuit 2 comprises a transistorized asymmetrical flip-flop circuit having variable resistors 16, 7, in an input bias circuit and in a feedback circuit connected between the transistors 5, 6, respectively. The input signal to circuit 2 applied between the base and emitter of transistor 6 is obtained, by way of a C.R. T-filter circuit 8, from across resistors 13, 14, in circuit 1, the currents flowing through resistors 13, 14, being in direct proportion to the traction motor current I 1  and terminal voltage V 1  of generator 15. The signal voltage between terminals a and b thus varies in proportion to the difference in outputs of the magnetic amplifiers 9, 10, applied across rectifier bridge circuits 11, 12, to terminals a, b. As the locomotive speed increases, I 1  decreases and V 1  increases, the input signal to circuit 2 increases to the threshold at which it switches between its two states causing transistor 5 to conduct and energize contactor coil 3 to weaken the motor field. The process is reversed when the locomotive slows. Semiconductor diode 17 prevents overvoltages across transistor 5 when the latter is non-conductive. A diode 18 in the emitter circuit of transistor 5 improves reliability of current blocking circuit 2 when transistor 5 is non-conductive.
