Title: Process and apparatus for degassing ferrous metals during casting
IPC: B22D18/06
Filed: 1954-12-14
Abstract: 763,872. Degassing ferrous metals. FORD MOTOR CO., Ltd. Dec. 14, 1954 [Dec. 28 1953], No. 36116/54. Class 72 [Also in Group XXII] A process for degassing ferrous metals comprises forming a body of molten metal, flowing the metal through a restricted throat into an evacuated chamber where it is shattered into droplets, collecting the droplets at the bottom of the chamber as a molten mass and discharging the molten mass through a barometric column, which leads directly to a continuous casting mould. As shown, molten metal is fed into a hopper 15 from which it flows through a nozzle 17, forming a restricted throat, into an evacuated chamber 18 where occluded gases and gaseous reaction products are removed from the spray of metal formed. The body of molten metal formed in the bottom of the chamber is removed through a barometric leg 21 to a continuous mould 25. The junction between the leg and the mould may be formed by a metallic bellows 26, the interior of which may contain an atmosphere of an inert gas, e.g. helium or argon. A stopper 22 may be used to prevent metal falling into the mould when starting up. The hopper 15 and the barometric leg 21 may include heating elements 14 which may be resistance heaters or induction heating coils. In a modification Fig. 2 (not shown) the end of the barometric leg may be bellmouthed and directly attached to the mould vertically or horizontally (Fig. 3. not shown).

Abstract: 1106797 Making super-conductors SIEMENS SHUCKERTWERKE AG 27 Aug 1965 [28 Aug 1964] 37065/65 Headings H1A A5 and A4D Material comprising a super-conductor, twocomponent, intermetallic compound region is produced by disposing the lower melting point metal between two leaves of the higher melting point, sealing the edges of the leaves and heattreating to cause diffusion and formation of the intermetallic compound. In one embodiment a 10Á tin tape 1 is placed between wider 30Á niobium tapes 2 and 3 and the edges of the niobium are then welded by electrodes 6 and 7. Subsequent heat-treatment for 1 hour at 1000-1200C diffuses the tin into the niobium and forms Nb 3 Sn. Welding may be effected by resistance welding (using if desired, intermediate Ti or Zr layers), ultrasonic welding or electron beam welding and water cooled rollers may be employed to prevent heating of the tin. One niobium tape may be made wider than the other and bent over to enclose the tin, and the lower melting point metal may be a coating on the niobium or other metal. The metals may consist of Nb, V or Ta with lower melting point metals Al, Ga, In or Sn; reference is made to V a Si as a super-conductor and also to prior art processes in which Nb3 Sn is deposited on a support by reduction of gaseous chlorides of Nb and Sn.

Abstract: 1,077,659. Pulse radar. RAYTHEON CO. Sept. 1, 1965 [Oct. 13, 1964], No. 37389/65. Heading H4D. In a pulse radar receiver, each pulse in the echo pulse train is stretched, in order that the bandwidth of a delay line, used in a coherent memory filter performing a spectrolanalysis of the stretched echo train, may be reduced. An echo pulse train 44, Fig. 2a, may comprise four consecutive echoes each of width #, with the four echoes occupying nearly all of the pulse interval To. The pulse train is passed via an AND gate (10), Fig. 1 (not shown), to a delay line (12) having a delay equal to To. The output of the delay line is fed back to the gate input, such that a signal 44, Fig. 2b of repeated pulse trains appears at the gate input. Gate (10) is opened by a pulse 46, Fig. 2e from a timing pulse generator (30) fed with radar synchronizing pulses. The signal 44 is fed to a gate (28) which is opened by pulses 48, Fig. 2f having a width # and spacing To + #. Gate (28) thus passes successive pulses of the train from successive trains, Fig. 2c. Each passed pulse activates a ringing circuit (38) to produce an expanded version, Fig. 2d, of the train 44, Fig. 2a. The ringing circuit operates for a period just less than To and is quenched by pulses from generator (30). The output of the ringing circuit is fed to the coherent memory filter. The invention is said to give greater range resolution capabilities.

Title: Nonrecursive interpolating digital filter
IPC: H03H17/00
Filed: 1975-09-12
Abstract: 1506009 Non-recursive digital filter PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 Sept 1975 [16 Sept 1974] 37642/75 Heading H3U A non-recursive interpolating digital filter generates output code words at a frequency f u  which are related to a sequence of input code words occurring at an input sampling frequency f, the ratio between f u  and f i  being a factor M/L where M and L are integers and M is greater than L and comprises a store 8 for successive input code words, a multiplier 10 to form products between the stored input words and weight factors, which may be stored in a ROM 9, and an adder 11 connected to the multiplier and which supplies (at frequency f u ) output code words given by the mathematical sum of the products formed by the multiplier within the output sampling period 1/f u , and where the store 8 is preceded by a buffer device 12 which receives the input code words and stores them for a variable time according to a control 7 and supplies them to the store 8 at intervals which are an integral multiple of the output sampling period 1/f u  apart. Preferably the control generates a periodic train of buffer read-out pulses with a period equal to M output sampling periods, each period of the train containing L buffer read-out pulses which are spaced from the start of the period by time intervals equal to such numbers of output sampling periods that these numbers when multiplied by L are greater than or equal to consecutive multiples of M. As shown oscillator 13 generates equally spaced pulses at a frequency (N/L) (f i ) which both control the shifts of the shift register store 8 and are applied to a divider 14 which divides them by N/M providing various outputs b, c, d of the same frequency (M/L)f i  but different phasing (Fig. 2, not shown). One of these outputs is applied to a second divider which divides by M to generate outputs e, f, g, h, i of the same frequency f i /L but of different phasing. The outputs 7 of the two dividers are connected to access the ROM 9 and to reset the accumulator 11 at the end of each cycle. The gates 15, 16, 17 and 20 provide an output j at a frequency f which is supplied to the input sampler 27 to generate the input code words at this frequency. A phase shifted output k at f i  is supplied by gate 23 to permit words stored in the buffer to pass gate 3. Two non regular pulse trains l, m are generated to control gates 4 and 5 which permit access to the store 8 and also vary its storage time by taking feed back either from the output or input of the last stage 83.
