Abstract: 879,670. Casting processes. INCA STEEL CO. Ltd. Sept. 23. 1959 [Oct. 2, 1958], No. 31531/58. Class 83 (1). A casting with an equiaxed crystal structure free from major segregation is made in a mould which is itself formed of, or the walls of which are wholly lined with a combustible composition which, on firing generates by its exothermic reaction sufficient heat to prevent, or substantially prevent, initial chilling of the melt and to delay cooling, the base of the mould being formed of or lined with the combustible composition or a heat-insulating material, and a combustible composition or heat-insulating material being applied to the surface of the melt. The exothermic composition may include aluminium powder &c. with one or more oxidizing agents such as alkali metal, nitrates, iron oxide, manganese oxide. and include a fluoride of alkali metal, sodium aluminium or potassium aluminium, silico- and boro-fluorides, together with a filler such as sand or grog and a binder such as sulphite lye, gum arabic and clay. Carbonaceous compositions based e.g. on charcoal or coke, and sand impregnated with oil may also be used. The exothermic lining may be backed by a refractory lining having vents communicating with vents in the mould and may be preformed. The facing surface of the exothermic material may be covered with a thin metal-impervious lining of e.g. mica, graphite, silica flour, cement in a carrier such as a resin solution, hardboard, cardboard, paper, glass, fibreglass.

Title: Improvements in the manufacture and production of vat dyestuffs of the dibenzanthrone series
IPC: C09B3/26
Filed: 1926-12-13
Abstract: 262,819. I. G. Farbenindustrie Akt.- Ges. Dec. 14, 1925, [Convention date]. Dibenzanthrone dyes are obtained by treating Bz1 : Bz1<1>-dibenzanthronyls 'with alkaline reducing agents. According to an example, Bz1 : Bz1<1>-dibenzanthronyl is boiled with caustic soda solution and sodium formaldehyde sulphoxylate and, after addition of more caustic soda and hydrosulphite, the vat is filtered and the dyestuff precipitated by an oxidizing agent such as sodium hypochlorite. Bz1 :Bz1<1>-Dibenzanthronyls can be obtained by treating Bz1-halogen-benzanthrones with metal powders, or by boiling Bz1-diazobenzanthrones in presence of cuprous chloride, or by oxidizing benzanthrones in acid solution. The Specification as open to inspection under Sect. 91 (3) (a) describes also the production of dibenzanthrones by treating Bz1 : Bz1<1>-dibenzanthronyls with alkaline condensing agents, and the production of dyestuffs from Bz1 Bz1<1>-dibenzanthronyl, Bz2 : Bz2<1>-dimethyl-Bz1 : Bz1<1>- dibenzanthronyl (obtained by acid oxidation of Bz2-methylbenzanthrone), and 6: 6<1>-dichlor-Bz1 : Bz1<1>-dibenzanthronyl (obtained by acid oxidation of 6-chlorbenzanthrone). This subjectmatter does not appear in the Specification as accepted.

Class 38(3) The equipment described in the parent Specification is modified so that the control of the motor IM is maintained when the controller MC is returned to the " off " position, contactors P'F, PR, being included for this purpose. When the controller MC is positioned for forward operation, for example, the contactor PF is energized to close contacts PF1, PF2. Contacts 51a are closed as soon as the brakes are released or the motor starts, the contactor PF being kept energized upon the return of the controller MC to its " off " position to call for a reduction of speed to zero, so that forward contactor F and dynamic braking contactor D remain -operative.

Abstract: 859,855. Sawtooth generating circuits. RANK CINTEL Ltd. Oct. 13, 1958 [Oct. 14, 1957; Aug. 21, 1958], Nos. 31984/57 and 26895/58. Class 40(6). A sawtooth current generator comprises deflection coils coupled to the anode circuit of a valve through a transformer, the grid of the valve being connected to positive potential through a resistor, a first feedback path being provided from the anode to the grid through a capacitance resistance circuit having a time constant similar to that of the coils and a second feedback circuit being provided from the secondary winding of the transformer to a point on the grid resistor to provide feedback proportional to the voltage drop in the resistive component of the impedence of the coils. Fig. 1 shows the blocking oscillator 3 which comprises an additional transformer winding 9 connected through a capacitor 10 to neutralize interelectrode capacitances of the valve. It also comprises a rectifier 12 coupled across winding section 8 to damp ringing which occurs in that section and to provide a current through winding 8 which offsets the effect of current drawn by the valve through the transformer. Negative pulses produced at the grid of the valve cause valve 13 to be cut off to produce the flyback in the deflection coils 16. Thereafter a substantially linear current is induced in the coils due to the positive voltage applied through resistors 20 and 21 to the grid and due to the feedback provided through a network 25, 26 having a time constant similar to that of the deflection coils. The linearity is further increased by additional feedback from potentiometer 31 throught the blocking capacitor 32, the feedback being proportional to the voltage drop in the resistive component of the coils. The feedback maintains the current in resistor 20 constant and resistor 33 and capacitor 24 are proportioned to remove the pulse component from the potential applied to the junction of resistors 20 and 21. Blocking capacitor 32 is also used in conjunction with a resistor 34 to integrate the voltage at the anode so as to provide a voltage at the grid which corrects for the geometry of the face of the cathode tube. Capacitor 18 by-passes unwanted high frequency current. The time constant of the primary of the transformer is preferably about half the scan duration. In Fig. 2 the feedback from the anode is derived from across a capacitor 25 of a network 26, 25 having a time constant similar to that of the deflection coils and the further feedback derived from capacitor 32 is supplied directly to the tap on the resistor 20, 21 the feedback voltage being of sawtooth form and being converted to parabolic form by the square law distortion in the valve. Capacitor 35 in addition to acting as a blocking capacitor introduces the sawtooth component into the grid voltage to compensate for transformer primary resistance. Potentiometer 28 permits adjustment of the amplitude of the output wave.
